Description

Processing machines used for multi-faceted processing of the same product

The present invention relates to a processing machine, particularly a processing machine used for processing multiple surfaces of the same product.

In the machining industry, it is sometimes necessary to rotate the same product, such as bearings, gears, etc., to perform multi-sided processing on the product.

Therefore, Chinese Patent No. CN208880226U provides a clamping tool for automobile bearing processing, including a tooling platform, a groove is opened on the top of the tooling platform, a motor mounting box is welded to the bottom of the tooling platform below the groove, a motor is installed inside the motor mounting box, and the end of the rotating shaft passes through the bottom of the groove and is fixed with a disc. The disc has a mounting slot inside. The upper end of the cavity is rotatably connected to the first gear via a cylindrical rod. A left-threaded rod is mounted in the inner ring of the bearing. The second gear is mounted on the surface of the left-threaded rod located inside the cavity. The end of the left-threaded rod is welded to the right-threaded rod, which is also mounted in the inner ring of the bearing. A clamping block is fixed to the top of each connecting rod.

The aforementioned patent facilitates the clamping and securing of bearing inner rings of varying sizes. The clamping process is relatively simple, and it also facilitates the processing of the bearing outer ring, making it more flexible to use.

However, the motor in the aforementioned patent directly drives the disc to rotate. When a larger bearing is machined and a larger disc is used, the motor may not have sufficient torque.

Therefore, the inventors propose a processing machine for processing multiple surfaces of a product, which is used to process a product. The processing machine for processing multiple surfaces of a product comprises: a lower plate; an upper plate pivotally connected to the lower plate; a tool holder adjacent to the upper plate and the lower plate, the tool holder being combined with a tool unit; a first gear coupled to the upper plate; a second gear adjacent to the upper plate, the second gear meshing with the first gear, and The diameter of the first gear is larger than the diameter of the second gear; and an actuator unit is connected to the second gear, which drives the second gear to rotate. By coupling the product to the upper plate or the first gear, the actuator unit drives the first gear and the upper plate to rotate via the second gear. The product rotates on the upper plate or the first gear relative to the tool unit, and the tool unit processes multiple sides of the product.

Furthermore, there is a track extending along a lengthwise direction, and the lower plate is movably coupled to the track. A screw extends along the lengthwise direction and is adjacent to the lower plate. A threaded plate is coupled to the lower plate and is threadedly connected to the screw. By pivoting the screw, the threaded plate moves relative to the screw, and the threaded plate in turn drives the lower plate to move along the lengthwise direction on the track relative to the tool holder.

Furthermore, an oil circuit is provided between the upper plate and the lower plate. The oil circuit has an inlet and an outlet extending outside the upper plate and the lower plate. The oil circuit forms an oil film between the upper plate and the lower plate, and the oil film contacts the upper plate and the lower plate.

Furthermore, a scoop is formed on a side of the upper plate facing the lower plate, and/or a side of the lower plate facing the upper plate, and the oil film adheres to the scoop.

Furthermore, a plurality of grooves are formed on a side of the upper plate away from the lower plate. Each groove has an opening and a stopper connected thereto, and the width of the opening is smaller than the width of the stopper.

Furthermore, there is a positioning member and a pressure plate. The positioning member has an extension portion and a positioning portion connected thereto, and the width of the extension portion is smaller than the width of the positioning portion. When the product is coupled to the upper plate, the positioning portion is engaged with the stop portion adjacent to the product, causing the extension portion to extend from the opening. The pressure plate then engages with the end of the extension portion distal from the positioning portion, corresponding to the product being coupled thereto. The pressure plate thereby presses the product against the upper plate.

A plurality of teeth are arranged around a circumference of the upper plate to form the first gear.

The gear ratio between the first gear and the second gear is between 40:1 and 70:1.

Based on the above technical features, the following effects can be achieved optimally:

1. By using a smaller second gear to drive the larger first gear, the burden on the actuator is reduced and multi-sided processing of the product is achieved.

2. Through the cooperation of the screw and threaded plate, the lower plate can be moved relative to the tool holder, making it easy to adjust according to product size and processing requirements.

3. Lubrication through an oil film reduces friction loss between the upper and lower plates.

4. Grooves can be used with positioning components, pressure plates, and even other processing equipment, allowing for convenient selection based on needs.

Taking into account the above technical features, the main functions of the present invention as a processing machine for processing multiple surfaces of the same product will be clearly demonstrated in the following embodiments.

Please refer to Figures 1 to 3, which illustrate an embodiment of the present invention applied to a processing machine for processing multiple surfaces of a single product, including:

A track 10 extends along a longitudinal direction D and is disposed on a base A. A portion of the track 10 is shown in FIG7 .

A lower plate 20 is movably coupled to the rail 10.

An upper plate 30 is pivotally connected to the lower plate 20. Preferably, a side of the upper plate 30 facing the lower plate 20 and/or a side of the lower plate 20 facing the upper plate 30 has a shovel pattern.

A tool holder 40 is adjacent to the upper plate 30 and the lower plate 20. The tool holder 40 is combined with a tool unit (not shown).

A first gear 50 is coupled to the upper plate 30.

A second gear 60 is adjacent to the upper plate 30 and engages with the first gear 50. The diameter of the first gear 50 is larger than the diameter of the second gear 60. Depending on the weight of the product B in Figure 5, the gear ratio between the first gear 50 and the second gear 60 can be between 40:1 and 70:1.

In a preferred embodiment of the present invention, a plurality of gears are provided around a circumference of the upper plate 30 to form the first gear 50.

An actuator unit 70 is connected to the second gear 60 and drives the second gear 60 to rotate. Preferably, the actuator unit 70 is a servo motor to achieve stepless operation.

A screw 80 extends along the length direction D and is adjacent to the lower plate 20.

A threaded plate 90 is coupled to the lower plate 20 and screwed to the screw rod 80.

An oil passage 100 is disposed between the upper plate 30 and the lower plate 20. The oil passage 100 has an inlet 1001 and an outlet 1002 extending outside the upper plate 30 and the lower plate 20. The oil passage 100 forms an oil film between the upper plate 30 and the lower plate 20. The oil film adheres to the shovel and contacts the upper plate 30 and the lower plate 20, thereby reducing frictional loss between the upper plate 30 and the lower plate 20.

Preferably, a storage barrel 1003 is connected to the inlet 1001 and the outlet 1002, and can be appropriately equipped with extraction equipment to extract oil from the storage barrel 1003 and pump it between the upper plate 30 and the lower plate 20.

Refer to Figures 3 and 4. By pivoting the screw 80 by hand or with a tool such as a wrench, the threaded plate 90 moves relative to the screw 80. The threaded plate 90, in turn, moves the lower plate 20 along the track 10 along the longitudinal direction D relative to the tool holder 40 and the base A. (See Figure 7 for the track 10.) This facilitates adjustment based on the dimensions and processing requirements of the product B shown in Figure 5.

Referring to Figures 4 to 6, the upper plate 30 has a plurality of grooves 301 on the side away from the lower plate 20. Each groove 301 has an opening 3011 and a stopper 3012 connected thereto, and the width of the opening 3011 is smaller than the width of the stopper 3012.

There is a positioning member 110 and a pressure plate 120. The positioning member 110 has an extension portion 1101 and a positioning portion 1102 connected thereto, and the width of the extension portion 1101 is smaller than the width of the positioning portion 1102.

When product B is attached to the upper plate 30, the positioning portions 1102 of the two positioning members 110 are engaged with the stop portions 3012 located on either side of the upper plate 30, adjacent to product B. This allows the extension portion 1101 to extend from the opening 3011. The pressure plate 120 is then tightened with a plurality of screws 130, corresponding to the end of the extension portion 1101 facing away from the positioning portion 1102, thereby pressing product B against the upper plate 30.

In actual implementation, other processing equipment, fixtures, etc. may be selected and combined with the groove 301 as needed to position the product B.

Please refer to Figures 1 and 7. After product B is attached to the upper plate 30, the actuator 70 drives the first gear 50 and the upper plate 30 via the second gear 60 to rotate. Product B then rotates relative to the tool unit on the upper plate 30, and the tool unit then processes multiple surfaces of product B.

Because the smaller second gear 60 drives the larger first gear 50 to rotate, the burden on the actuator 70 is reduced, and multi-faceted processing of product B is also possible.

The description of the above embodiments should provide a comprehensive understanding of the operation, use, and efficacy of the present invention. However, the above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Simply equivalent variations and modifications made within the scope of the patent application and the description of the invention are also covered by the present invention.
