Description
Technical Field

Background
In the production process of the 3D round product, after master batch slicing and hot bending forming, a semi-finished product is usually required to be processed through a CNC engraving and milling machine so as to remove redundant materials and obtain a product with concentricity and flange surface flatness meeting requirements.
FIG. 1 is a schematic view of a CNC positioning fixture used in the prior art for machining. As shown in fig. 1, the 3D round product to be processed is placed on the positioning fixture at the bottom of the engraving and milling machine, and because the fixture design has no accurate positioning reference, the positioning needs to be performed by leaning on the convex shape of the product to be positioned through the external L-shaped explorator. Because of the adopted appearance positioning structure, the center of the concave cavity of the product cannot be found, and the concentricity of the product processed by the positioning method is poor and cannot be ensured.
FIG. 2 is a schematic diagram of another method of machining using CNC locating fixtures as used in the prior art. As shown in fig. 2, in order to further improve the positioning accuracy of the product, the method uses a 5-axis CNC device to position a 3D-shaped concave cavity by a probe to process an appearance and a flange positioning reference, and then turns over to process a convex surface by adopting the appearance and the flange positioning reference on another CNC machine, so as to meet the requirement of the product size. The method can process the concentricity of the product to a certain level compared with the method shown in fig. 1 by adopting the probe to position the center of the concave cavity and processing the appearance and the flange standard for convex surface positioning, but is used for using secondary positioning, and comprises the positioning tolerance of probe contact and the positioning tolerance of the L-shaped explorator in the secondary positioning, so that the positioning tolerance is larger. Meanwhile, the 5-axis CNC probe mode is long in time consumption, the number of required equipment is high, the cost is high, and the future mass production is hindered.

Fig. 3 is a flowchart of a processing method for a 3D round product according to the present invention. As shown in fig. 3, the processing method for a 3D circular product provided by the embodiment of the invention includes the following steps:
step S1, cutting, turning and hot bending forming are carried out on a raw material master slice to obtain a product to be processed with a specified size;
Specifically, in this embodiment, first, a desired portion is cut out from a raw material master, and when the material is cut out, accurate measurement is required to ensure that the cut portion conforms to the design size, so as to avoid wasting or disqualification in the subsequent process. Then, the cut material is turned to a prescribed circular size. In the process, a lathe or a numerical control lathe is used for precision machining, so that the circular shape and the circular size are ensured to meet the standard requirements. Then, the material is heated to be soft, bending forming can be carried out according to design requirements, and in the hot bending process, the factors such as temperature, bending angle and bending radius need to be precisely controlled so as to ensure that the product has no cracks, deformation or uneven places. Therefore, a product to be processed with the shape and the size meeting the design requirements is formed, but the concentricity and the flange flatness of the product also need to be further processed and adjusted.
S2, classifying the to-be-processed products by using inner cavity profiling classification clamps with different sizes, and selecting an inner cavity profiling positioning clamp matched with the inner cavity of the to-be-processed products;
specifically, in this embodiment, different sizes of inner cavity profiling positioning fixtures are designed to achieve processing and adjustment of concentricity and flange flatness of the product, so before processing, the product to be processed needs to be classified by a matched inner cavity profiling classification fixture, and an inner cavity profiling positioning fixture matched with the inner cavity profiling positioning fixture is selected.
Further, as shown in fig. 4, the cavity profiling classifying fixture provided by the invention comprises a classifying base 110, a classifying cavity positioning part 120 and a classifying cavity profiling part 130 which are concentrically arranged. The classifying cavity positioning portion 120 is formed on the upper surface of the classifying base 110, the classifying concave surface profiling portion 130 is formed on the upper surface of the classifying cavity positioning portion 120, the lower surface of the classifying cavity positioning portion 120 is on the same plane with the flange surface of the product to be processed, the outer side wall of the classifying cavity positioning portion 120 is matched with the side wall of the inner cavity of the product to be processed, the upper surface of the classifying concave surface profiling portion 130 is matched with the concave surface of the inner cavity of the product to be processed, after the product to be processed is mounted into the inner cavity profiling classifying clamp, the side wall of the inner cavity of the product to be processed is tightly attached to the outer side wall of the classifying cavity positioning portion 120, and the concave surface of the inner cavity of the product to be processed is tightly attached to the upper surface of the classifying concave surface profiling portion 130. Thus, the identification of the size of the inner cavity of the product is realized on the premise of not directly using the measuring equipment and the CNC probe.
Further, in this embodiment, the inner cavity profiling classifying fixture further includes a classifying vacuum hole 140 penetrating through the lower surface of the classifying base and the upper surface of the classifying cavity positioning portion and concentric with the classifying base, and the classifying concave profiling portion further includes a classifying cavity 150 penetrating through the upper surface and the lower surface of the classifying concave profiling portion and concentric with the classifying concave profiling portion, and the diameter of the classifying cavity is larger than that of the classifying vacuum hole.
In this embodiment, the base is the support portion of the entire clamp, which provides stable support, ensuring that the clamp does not shift during operation. The sorting base is concentric, i.e. all other parts (such as the positioning and profiling parts) are designed and arranged centered on the base. The classifying cavity locating part 120 is located on the upper surface of the classifying base and is in butt joint with the flange surface of the product to be processed, so that the locating precision of the product in the clamp is ensured, and the outer side wall of the classifying cavity locating part is closely matched with the inner cavity side wall of the product to be processed, so that the product can be effectively ensured not to deviate or shake in the processing process. The classifying concave profiling part 130 ensures that the inner cavity of the product is accurately positioned by closely contacting with the concave surface of the inner cavity of the product to be processed. Meanwhile, in order to facilitate fixing and positioning of the product, the fixture is designed with a vacuum adsorption function. The classifying vacuum holes penetrate through the classifying base, and products to be processed can be adsorbed through vacuum, so that the products are ensured to be stable and motionless in the clamp. The classifying cavity is concentric with the concave profiling part, can provide suction force, helps to fix products and prevents errors caused by unstable clamps.
Further, in this embodiment, the product to be processed after the heat bending is classified using the lumen profiling classification jig, and diameters of base side walls of different lumen profiling classification jigs are different, for example, are different by 0.02mm. The concave surface of the product is placed on the clamp downwards in the middle, two fingers are used for simultaneously contacting the two ends of the product, one of the two fingers is used for pressing downwards, and the adsorption is realized through the vacuum holes. For products which cannot be pressed in, the inner cavity profiling classification clamp is larger in size and needs to be replaced with the inner cavity profiling classification clamp smaller in size, for products which are loose, the inner cavity profiling classification clamp is smaller in size and needs to be replaced with the inner cavity profiling classification clamp larger in size, and for products which are not loose, the inner cavity profiling classification clamp is proper in size. Therefore, the problem that different products cannot be matched with the standard clamp due to the size difference is solved through flexible adjustment of the clamp size. The device enables products with different inner cavity sizes to be processed by selecting the proper clamp without depending on precise measuring equipment, thereby saving time and improving production efficiency. The use of such clamps can greatly improve the automation level and accuracy of the production line, especially in mass production. Thus, step S2 comprises:
s21, centering the concave surface of the product to be processed downwards on an inner cavity profiling classifying clamp;
step S22, pressing down the product to be processed, if the product to be processed deflects, the processed product cannot be placed into the inner cavity profiling classifying clamp, then proceeding to step S23, if the product to be processed loosens in the inner cavity profiling classifying clamp after being placed into the inner cavity profiling classifying clamp, proceeding to step S24, if the product to be processed does not loosen in the inner cavity profiling classifying clamp after being placed into the inner cavity profiling classifying clamp, proceeding to step S25;
step S23, replacing the inner cavity profiling classifying clamp, wherein the size of the inner cavity profiling classifying clamp after replacement is smaller than that of the inner cavity profiling classifying clamp before replacement, and returning to the step S21;
Step S24, replacing the inner cavity profiling classifying clamp, wherein the size of the replaced inner cavity profiling classifying clamp is larger than that of the inner cavity profiling classifying clamp before replacement, and returning to the step S21;
and S25, selecting an inner cavity profiling positioning clamp matched with the inner cavity of the product to be processed according to the determined size of the inner cavity profiling classification clamp.
In the embodiment, the proper positioning clamp is selected for the product to be processed through the inner cavity profiling classifying clamp, so that the product can be accurately positioned in the processing process, and particularly, the concentricity and the flange flatness of the product are ensured. Through the inner cavity profiling classification clamp, the proper clamp size can be rapidly judged and matched according to the inner cavity characteristics of a product under the condition that measuring equipment or CNC probes are not directly used, and an accurate positioning basis is provided for subsequent processing.
S3, placing the product to be processed on the selected inner cavity profiling positioning clamp, and processing the flange surface and the convex profile of the product to be processed through 3-axis CNC equipment;
specifically, in this embodiment, the product to be processed is classified by the matched inner cavity profiling classification clamp, and then the matched inner cavity profiling positioning clamp is selected. And processing the product to be processed by using the inner cavity profiling positioning clamp and the 3-axis CNC equipment.
Further, in an embodiment of the present invention, as shown in fig. 5 to 7, the inner cavity profiling positioning fixture includes a positioning base 210, a positioning cavity positioning portion 220 and a positioning concave profiling portion 230 that are concentrically disposed, the positioning cavity positioning portion 220 is formed on an upper surface of the positioning base 210, the positioning concave profiling portion 230 is formed on an upper surface of the positioning cavity positioning portion 220, an outer sidewall of the positioning cavity positioning portion is matched with a sidewall of an inner cavity of the product to be processed, and an upper surface of the positioning concave profiling portion is matched with a concave surface of the inner cavity of the product to be processed. Through the outer side wall of location cavity location portion and the inner chamber lateral wall closely match of waiting to process the product, location concave surface profile modeling portion through with waiting to process the concave surface in the product inner chamber in close contact with, can ensure effectively that the product can not take place the skew or rock in the course of working, ensure that the inner chamber of product and anchor clamps are concentric, and then guaranteed the concentricity of product. The diameter of the lower surface of the positioning cavity positioning part 220 is greater than the diameter of the upper surface of the positioning base 210, and the lower surface of the positioning cavity positioning part is located above the plane where the flange surface of the product to be processed is located, so that the product is mounted on the inner cavity profiling positioning fixture, the upper surface of the positioning cavity profiling part is in contact with the concave surface of the inner cavity of the product to be processed, the outer side wall of the positioning cavity positioning part is in contact with the side wall of the inner cavity of the product to be processed, and meanwhile, a hollowed-out space is formed between the flange surface of the product and the lower surface of the positioning cavity positioning part, so that CNC equipment is convenient for processing the flange surface of the product to be processed. Meanwhile, as the inner cavity profiling positioning clamp realizes the inner cavity positioning of a product to be processed, the inner cavity profiling positioning clamp can be realized only by using 3-axis CNC equipment when the convex profile is processed.
In this embodiment, the positioning base is used as a base for supporting the entire jig and the product to be processed, and the upper surface thereof is a mounting surface for positioning the concave positioning portion. The outer side wall of the positioning concave cavity positioning part is tightly matched with the inner cavity side wall of the product to be processed. Through the structure, the clamp can ensure that the inner cavity of the product is concentric with the clamp, and the offset is prevented in the processing process. The positioning concave surface profiling part is in concave contact with the inner cavity of the product to be processed, so that further stability is provided, and shaking is avoided in the processing process. Through the design that the lower surface of the positioning part of the positioning concave cavity is higher than the flange surface of the product to be processed, when the flange surface is processed, the tight fit between the clamp and the product can be kept, meanwhile, the clamp and the processing surface are prevented from interfering, and the smooth processing of the flange surface is ensured.

The traditional machining method generally needs to use 5-axis CNC equipment to combine with a probe to locate and machine a product, but the design scheme can only use 3-axis CNC equipment to machine through the reasonable structure of the inner cavity profiling locating clamp, so that the equipment investment cost is reduced.
Further, in an embodiment of the present invention, the inner cavity profiling positioning fixture further includes a positioning vacuum hole 240 formed through a lower surface of the positioning base and an upper surface of the positioning cavity positioning portion and concentric with the positioning base, and the positioning concave profiling portion further includes a positioning cavity 250 formed through an upper surface and a lower surface of the positioning concave profiling portion and concentric with the positioning concave profiling portion, and a diameter of the positioning cavity is larger than a diameter of the positioning vacuum hole. The vacuum hole is located between the lower surface of the positioning base and the upper surface of the positioning concave cavity positioning part, and the product to be processed can be better fixed on the clamp in a vacuum adsorption mode. The vacuum holes provide an additional holding force during processing, making the product more tightly in contact with the fixture, thereby reducing vibration and deflection during processing. The positioning concave surface profiling part is provided with a positioning cavity concentric with the positioning concave surface profiling part, and the stability of the clamp can be further improved through the cavity design, so that the inner cavity profiling positioning clamp can more effectively position the inner cavity of a product. The diameter of the positioning cavity is larger than that of the vacuum hole, and the design not only increases the adsorption force, but also contributes to improving the overall positioning effect.

Compared with the traditional positioning mode requiring 5-axis CNC equipment and probes, the invention only needs to use 3-axis CNC equipment, thereby greatly reducing equipment investment and lowering cost.

Whether the inner cavity of the product is concentric with the center of the convex surface directly influences the overall shape and the function of the product, and particularly in the assembly process, if the concentricity is not good, mismatch or use faults can be caused. The flatness of the flange face is critical to ensure that the product is securely mounted to other components. The width of the flange surface is directly related to the contact surface and the matching precision of the parts in assembly.
And S5, conveying the product to be processed, of which the concentricity, the flange surface flatness and the flange surface width reach the standards, to a enterprise polishing procedure.
