Description

An inner fin cutting and upper knife processing jig

technical field

The invention relates to the technical field of tooling and jigs, in particular to an inner fin cutting and upper-knife processing jig.

Background technique

As shown in Figure 3 and Figure 4, an inner fin cutting upper knife is made of cemented carbide with a shape of 244mm in length and a 17.1° slope at the end. Since longitudinal grinding is used in the machining process, and the longitudinal effective distance of the existing machine is only about 160mm, only two clamping and tooling can be selected, and the cemented carbide material is basically non-magnetic, so it is difficult to fix the machining angle. It is more difficult to clamp, and the processing cannot be completed smoothly.

SUMMARY OF THE INVENTION

Based on the above problems, the purpose of the present invention is to provide an inner fin cutting upper knife processing jig, which can be reliably clamped according to the shape of the above cutting upper knife, so as to facilitate processing, especially the shaping of the edge angle, to ensure the machining accuracy and parts. quality.

For achieving the above object, the present invention adopts the following technical solutions:

An inner fin cutting and upper knife processing jig, which includes a positioning block and a pressing block. The positioning block is provided with a placement groove, and the part to be processed is placed in the placement groove, and the inclined surface of the part to be formed is horizontal. The block is located on one side of the positioning block, and the pressing block is provided with a convex part, which is pressed on the part, so as to cooperate with the positioning block to form a reliable clamping of the part for grinding processing.

In particular, the length of the positioning block and the pressing block is 0.5-0.8 of the length of the part.

In particular, after completing the machining of half the length of the part in one clamping, the part, the positioning block and the pressing block are rotated 180 degrees to be re-clamped to complete the machining of the other half of the length.

In particular, the positioning block and the pressing block are made of magnetic materials and are placed on the magnetic workbench.

In particular, the part to be processed on the part protrudes into the gap between the positioning block and the pressing block, and the inclined surface of the part to be formed edge is higher than the upper surface of the raised part.

To sum up, the beneficial effects of the present invention are that the inner fin cutting and upper knife processing jig realizes accurate positioning and reliable fixing of parts for parts of specific shapes and materials and their target molding shapes, and forms a molding surface angle that is easy to process. , and it is beneficial to the two processing operations of the tool, which can meet the process requirements and improve the processing efficiency.

Detailed ways

Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to explain the present invention and should not be construed as limiting the present invention.

In the description of the present invention, unless otherwise expressly specified and limited, the terms "connected", "connected" and "fixed" should be understood in a broad sense, for example, it may be a fixed connection, a detachable connection, a mechanical The connection can also be an electrical connection, it can be a direct connection, or an indirect connection through an intermediate medium, and it can be an internal connection between two elements or an interaction relationship between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

In the description of the present invention, unless otherwise expressly specified and limited, a first feature "on" or "under" a second feature may include direct contact between the first feature and the second feature, or may include the first feature and the second feature is not in direct contact but through another feature between them. Also, the first feature being "above", "over" and "above" the second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is level higher than the second feature. The first feature is "below", "below" and "below" the second feature includes the first feature is directly below and diagonally below the second feature, or simply means that the first feature has a lower level than the second feature.

The technical solutions of the present invention will be further described below with reference to the accompanying drawings and through specific embodiments.

Please refer to FIG. 1 and FIG. 2 , this preferred embodiment provides an inner fin cutting and upper knife processing jig, which includes a positioning block 1 and a pressing block 2. The positioning block 1 and the pressing block 2 here are preferably Magnetic material, so that it can be easily placed and fixed on the magnetic workbench 7.

The positioning block 1 is provided with a placement groove 3, the part 5 to be processed is placed in the placement groove 3, and the inclined surface of the part 5 to be formed cutting edge 6 is horizontal.

Specifically, according to the angle adjustment of the part 5 to be formed, the groove bottom of the placement groove 3 is set at an inclination of 17.1°, so as to level the slope of the cutting edge 6, and the to-be-processed part on the part 5 extends out of the positioning block 1 and the pressing block 2 In the gap, and the inclined surface of the cutting edge 6 of the part 5 to be formed is higher than the upper surface of the raised part 4 .
