technical field

The invention relates to the technical field of tooling and jigs, in particular to a jig for inner wing cutting and upper knife processing.

Background technique

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

Contents of the invention

Based on the above problems, the object of the present invention is to provide a processing fixture for cutting the upper knife of the inner wing, which can be reliably clamped for the shape of the upper knife for cutting, so as to facilitate processing, especially the forming of the cutting edge angle, to ensure the machining accuracy and the quality of the parts. quality.

For reaching above-mentioned purpose, the present invention adopts following technical scheme:

A jig for inner wing cutting and upper knife processing, which includes a positioning block and a pressing block. The positioning block is provided with a placement groove, and the parts to be processed are placed in the placement groove, and the slope of the cutting edge of the part to be formed is horizontal and pressed. The block is located on one side of the positioning block, and the pressing block is provided with a raised part, and the raised part is covered 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 parts.

In particular, after half the length of the part is processed in one clamping, the part, positioning block, and pressing block are rotated 180 degrees to re-clamp to complete the processing of the other half of the length.

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

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

To sum up, the beneficial effect of the present invention is that the inner wing cutting upper knife processing jig realizes accurate positioning and reliable fixing of parts for parts with specific shapes and materials and their target molding shapes, and forms a molding surface angle that is convenient for processing , and it is beneficial to two cutting operations, which meets the process requirements and improves the processing efficiency.

Detailed ways

Embodiments of the present invention will be described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The embodiments described below by referring to the figures 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 clearly stipulated and limited, the terms "connected", "connected" and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or a mechanical connection. A connection can also be an electrical connection, a direct connection, or an indirect connection through an intermediary, or an internal connection between two elements or an interaction relationship between two elements. Those of ordinary skill in the art can understand the specific meanings of the above terms in the present invention according to specific situations.

In the description of the present invention, unless otherwise clearly specified and limited, a first feature being "on" or "under" a second feature may include direct contact between the first feature and the second feature, or include the first feature Not in direct contact with the second feature but through another feature therebetween. Moreover, "above", "above" and "above" the first feature on the second feature include that the first feature is directly above and obliquely above the second feature, or simply means that the first feature is horizontally higher than the second feature. "Below", "beneath" and "under" the first feature to the second feature include that the first feature is directly below and obliquely 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 in conjunction with the accompanying drawings and through specific implementation methods.

Please refer to Fig. 1 and shown in Fig. 2, this preferred embodiment provides a kind of inner wing cut-off upper knife processing fixture, and it comprises positioning block 1 and pressing block 2, and positioning block 1, pressing block 2 here are preferably The magnetic material is fixed on the magnetic workbench 7 for convenient placement.

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

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

The pressing block 2 is located on one side of the positioning block 1, and the pressing block 2 is provided with a raised part 4, and the raised part 4 is pressed on the part 5, so as to cooperate with the positioning block 1 to form a reliable clamping of the part 5, so that Grinding.

Since the length of the part 5 is longer than the longitudinal processing stroke of the equipment, the length of the positioning block 1 and the pressing block 2 is preferably 0.5 to 0.8 of the length of the part 5. 1. The positioning block 1 and the pressing block 2 are rotated 180 degrees and re-clamped to complete the processing of the other half length, which meets the design requirements of the two-time cutting process of the long cutting edge 6 .

To sum up, the above-mentioned inner wing cutting upper knife processing jig realizes accurate positioning and reliable fixing of parts for parts with specific shapes and materials and their target molding shapes, and forms a molding surface angle that is convenient for processing, and is conducive to two times of cutting The processing operation meets the process requirements and improves the processing efficiency.
