Description

Inner fin cutting upper cutter machining jig

Technical Field

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

Background

As shown in figures 3 and 4, the inner fin cutting upper knife is made of hard alloy, has the external shape of 244mm and has the end cutting edge with the inclination of 17.1 degrees. Because the longitudinal grinding is adopted in the processing process, the longitudinal effective distance of the existing machine is only about 160mm, the clamping and knife-connecting processing can only be selected twice, the hard alloy material is basically nonmagnetic, the fixing is difficult during the processing angle, the clamping is difficult, and the processing can not be completed smoothly.

Disclosure of Invention

Based on the problems, the invention aims to provide the inner fin cutting upper knife machining jig which is used for reliably clamping the shape of the cutting upper knife so as to facilitate machining, particularly forming of a cutting edge angle and ensure machining precision and part quality.

In order to achieve the above purpose, the invention adopts the following technical scheme:

the utility model provides an interior wing cuts off upper cutter processing tool, its includes locating piece and compact heap, has seted up the standing groove on the locating piece, and the part of waiting to process is placed in the standing groove, and makes the inclined plane of part waiting to take shape the blade level, and the compact heap is located one side of locating piece, is provided with the bellying on the compact heap, and the bellying gland is on the part to form reliable clamping with the locating piece cooperation to the part, so that abrasive machining.

In particular, the lengths of the positioning block and the compacting block are 0.5-0.8 of the length of the part.

Specifically, after one clamping is finished, the part, the positioning block and the compacting block are rotated for 180 degrees to be clamped again, and the other half of the part is finished.

Particularly, the positioning block and the compacting block are made of magnetic materials and are placed on a magnetic workbench.

In particular, the part to be processed extends out of the gap between the positioning block and the compression block, and the inclined plane of the cutting edge to be formed of the part is higher than the upper surface of the protruding part.

In summary, the inner fin cutting upper cutter processing jig has the beneficial effects that aiming at parts with specific shapes and materials and target forming shapes thereof, the parts are accurately positioned and reliably fixed, forming surface angles convenient to process are formed, two cutter receiving processing operations are facilitated, the process requirements are met, and the processing efficiency is improved.

Detailed Description

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

In the description of the present invention, unless explicitly stated and limited otherwise, the terms "connected," "connected," and "fixed" are to be interpreted broadly, as for example, they may be fixedly connected, or may be detachably connected, or may be electrically connected, or may be directly connected, or may be indirectly connected through an intermediary, or may be in communication with one another in two elements or in an interaction relationship between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.

In the description of the present invention, unless explicitly stated and limited otherwise, a first feature "above" or "below" a second feature may include the first feature and the second feature being in direct contact, or may include the first feature and the second feature not being in direct contact but being in contact by another feature therebetween. Moreover, a first feature being "above," "over" and "on" a second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the first feature is higher in level than the second feature. The first feature being "under", "below" and "beneath" the second feature includes the first feature being directly under and obliquely below the second feature, or simply means that the first feature is less level than the second feature.

The technical scheme of the invention is further described below by the specific embodiments with reference to the accompanying drawings.

Referring to fig. 1 and 2, the present preferred embodiment provides an inner fin cutting upper cutter processing fixture, which includes a positioning block 1 and a pressing block 2, wherein the positioning block 1 and the pressing block 2 are preferably made of magnetic materials, so as to be conveniently placed and fixed on a magnetic workbench 7.

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

Specifically, according to the angle adjustment to be formed of the part 5, the bottom of the groove of the placing groove 3 is inclined by 17.1 degrees so as to level the inclined plane of the cutting edge 6, the part to be processed on the part 5 extends out of the gap between the positioning block 1 and the compression block 2, and the inclined plane of the cutting edge 6 to be formed of the part 5 is higher than the upper surface of the protruding part 4.

The compressing block 2 is positioned on one side of the positioning block 1, the compressing block 2 is provided with a protruding part 4, and the protruding part 4 is pressed on the part 5, so that the part 5 is reliably clamped by being matched with the positioning block 1, and the grinding is facilitated.

Because the length of the part 5 is longer and exceeds the longitudinal processing stroke of the equipment, the lengths of the positioning block 1 and the compression block 2 are preferably 0.5-0.8 of the length of the part 5, and after one-time clamping is finished, the part 5, the positioning block 1 and the compression block 2 are rotated 180 degrees to be clamped again, so that the processing of the other half length is finished, and the design requirement of two-time cutter receiving processing of the strip cutting edge 6 is met.

In conclusion, the inner fin cutting upper cutter machining jig aims at parts with specific shapes and materials and target forming shapes thereof, achieves accurate positioning and reliable fixing of the parts, forms a forming surface angle convenient to machine, facilitates two-time cutter receiving machining operation, meets process requirements, and improves machining efficiency.

The above embodiments merely illustrate the basic principles and features of the present invention, and the present invention is not limited to the above examples, but can be variously changed and modified without departing from the spirit and scope of the present invention, which is within the scope of the present invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
