Description

A die processing jig

technical field

The utility model relates to a jig, in particular to a jig for processing a die.

Background technique

Dies and punches are the core components in the cold stamping die industry. At present, in the air-conditioning fin mold, the number of dies and punches is very large, and the number of dies and punches in each pair of molds averages more than a thousand sets, of which the number of ordinary dies and punches accounts for 70%. , as shown in Figure 1, is a schematic diagram of the structure of the common die of the air-conditioning fin mold, and its inner hole is a through hole. Use a μ meter to make a meter to ensure the concentricity and straightness of the part, and finally use a special grinding head for the inner hole to process the inner hole. However, this processing method requires a lot of waste in clamping and metering operations for each ordinary die. The time, and the scrap rate is high, therefore, urgently need to be solved.

Utility model content

The purpose of this utility model is to address the above problems, to provide a die processing fixture, to solve the problem that the existing die adopts a three-jaw chuck to clamp the outer diameter, use a μ meter to make a meter to ensure the concentricity and straightness of the parts, and then For processing, the operation is cumbersome, the operation time is long, the efficiency is low, and the scrap rate is high.

The purpose of this utility model is to realize through the following technical solutions:

A die processing jig, comprising a jig body, the jig body is provided with a positioning hole in the axial direction to form a tight sliding fit with the die, the positioning hole is axially concentric with the jig body, and the jig body A locking hole is opened in the radial direction of the body, and the locking hole communicates with the positioning hole, and a locking piece for locking the die is arranged in the locking hole.

As a preferred solution of the present invention, the locking hole is a threaded hole, and the locking member is a screw.

As a preferred solution of the present utility model, the positioning holes include a first positioning hole located at one end of the jig body and a second positioning hole located at the other end of the jig body, and the diameter of the first positioning hole is larger than that of the second positioning hole. The aperture of the hole.

As a preferred solution of the present utility model, the inside of the jig body is provided with a relief hole communicating with the first positioning hole and the second positioning hole, and the diameter of the relief hole is larger than that of the first positioning hole , and the diameter of the relief hole is larger than the diameter of the second positioning hole.

The beneficial effect of the utility model is that the jig body of the die processing jig is axially concentric with the positioning hole, and only the straightness and concentricity of the jig body can be ensured during processing, so that the die can be fixed. Inner hole processing, compared with the traditional method of processing a die and punching a u table, has the characteristics of convenient operation, high efficiency and high yield.

detailed description

The technical scheme of the utility model will be further described below in conjunction with the accompanying drawings and through specific embodiments. It can be understood that the embodiments described here are only used to explain the utility model, rather than limit the utility model.

Please refer to Fig. 2 and Fig. 3, Fig. 2 is a schematic structural diagram of a die processing jig of the present invention; Fig. 3 is a schematic diagram of a use state of a die processing jig of the present invention.

In this embodiment, a jig for processing a die includes a jig body 7, the jig body 7 is provided with positioning holes 1 and 2 that form a tight-slip fit with the die 6 in the axial direction, and the positioning holes 1 and 2 include a first positioning hole 1 located at the left end of the jig body 7 and a second positioning hole 2 located at the right end of the jig body 7, the aperture of the first positioning hole 1 is larger than the aperture of the second positioning hole 2, and the The positioning holes 1, 2 are axially concentric with the jig body 7, and the inside of the jig body 7 is provided with a relief hole 3 communicating with the first positioning hole 1 and the second positioning hole 2, and the diameter of the relief hole 3 is Greater than the aperture of the first positioning hole 1, and the aperture of the relief hole 3 is greater than the aperture of the second positioning hole 2, the radial direction of the jig body 7 is provided with a locking hole 4, and the locking hole 4 is a threaded hole, and The locking hole 4 communicates with the positioning holes 1 and 2, and a screw 5 for locking the die 6 is arranged in the locking hole 4 .

In actual use, considering that the outer diameter tolerance of the die 6 will be controlled within 0.01mm, which is 9.998±0.005mm, therefore, with 0.005mm as the boundary, the die 6 is divided into two sizes, and the size is slightly smaller. The second positioning hole 2 at the right end of the jig body 7 is clamped, and the first positioning hole 1 at the left end of the jig body 7 is used for clamping the slightly larger size.

When in use, first fix the jig body 7 on the three-jaw chuck of the grinding machine, use a μ gauge to check the straightness and concentricity of the jig body 7, and then install the die 6 into the corresponding positioning holes 1 and 2 In the middle, tighten the screw 5, the inner hole of the die 6 can be processed with a special inner hole grinding head. After the processing is completed, loosen the screw 5 to take out the die 6, put it into the next die 6, and tighten the screw 5. At this time The machine can be directly processed without a watch, and the operation is convenient and efficient, which greatly improves the processing quality and efficiency of the batch die 6 .

The above embodiments only set forth the basic principles and characteristics of the present utility model, and the present utility model is not limited by the above-mentioned embodiments. Under the premise of not departing from the spirit and scope of the present utility model, the present utility model also has various changes and changes. These Variations and changes are within the scope of the claimed invention. The scope of protection required by the utility model is defined by the appended claims and their equivalents.
