Description

Technical Field

[0001] This utility model relates to the field of machining auxiliary tooling technology, and to a tooling for machining riveting holes in a semi-circular block. Background Technology

[0002] Flexible components are frequently used in modern industry. The design of these components varies depending on the application scenario. For example... Figure 1 The elastic component shown includes two symmetrically arranged semi-circular arc blocks 1 and a spring piece 2 for connecting the two semi-circular arc blocks 1. Blind holes are opened on the irregular arc side of the semi-circular arc block 1. Specifically, the spring piece 2 is attached to the semi-circular arc block 3 using a rivet 3. The technical difficulty of the above-mentioned elastic component lies in the processing of the riveting holes on the semi-circular arc blocks. Currently, the riveting hole processing process is as follows: centering → drilling. This process is inconvenient in operation. Centering and drilling on an irregular arc requires high skill from the operator, resulting in low product yield and low processing efficiency.

[0003] Therefore, developing a tooling for machining riveting holes in semi-circular blocks that is efficient and easy to operate is of great practical significance. Utility Model Content

[0004] Due to the aforementioned defects in the existing technology, this utility model provides a semi-circular block riveting hole processing fixture with high processing efficiency and convenient operation, in order to solve the problems of high operator requirements, low product yield and low processing efficiency in semi-circular block riveting hole processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A tooling for machining riveting holes in a semi-circular block, including a tooling base plate;

[0007] A clamping cylinder is fixed on the tooling base plate, and a top block is fixed on the drive rod of the clamping cylinder. A fixture for arranging a semi-circular block is also placed on the tooling base plate, and the fixture is located on the side of the top block away from the clamping cylinder. A fixture fixing plate that is fixed to the tooling base plate is provided on the side of the fixture away from the top block.

[0008] The fixture has a semi-circular block arrangement groove in the middle for accommodating and limiting the semi-circular block, and a riveting hole alignment hole on the outer wall of the fixture that matches the riveting hole of the semi-circular block.

[0009] This utility model discloses a fixture for machining the riveting holes of a semi-circular block. The fixture has a reasonable structural design. The semi-circular block is placed inside a clamp, which is then placed in front of a top block. A clamping cylinder is used to tighten the clamp, and with the cooperation of the clamp fixing plate, the clamp, i.e., the semi-circular block, can be fixed. The riveting holes of the semi-circular block inside the fixture can be quickly positioned using the riveting hole alignment holes on the clamp that match the riveting holes on the semi-circular block. A drill bit passes through the riveting hole alignment holes to machine the riveting holes of the semi-circular block. This fixture has great application potential.

[0010] As a preferred technical solution:

[0011] As described above, a tooling for machining riveting holes for semi-circular arc blocks includes a semi-circular arc block arrangement groove that accommodates two oppositely arranged semi-circular arc blocks and limits their movement.

[0012] The above-described fixture for machining riveting holes in a semi-circular block has a flat outer wall for the fixture with riveting hole alignment holes.

[0013] The fixture has rivet holes and alignment holes on its four outer walls, and the four outer walls form a square structure.

[0014] As described above, the fixture for machining riveting holes of semi-circular blocks has multiple riveting hole alignment holes arranged in a row on one outer wall of the fixture. This means that the fixture can simultaneously fix multiple semi-circular blocks (two semi-circular blocks arranged opposite each other form a group, and multiple groups of semi-circular blocks can be fixed), reducing the clamping frequency of the semi-circular blocks and improving the machining efficiency.

[0015] As described above, in a semi-circular block riveting hole machining fixture, the clamping cylinder is fixed to the fixture base plate by a cylinder fixing block.

[0016] As described above, in a semi-circular block riveting hole machining fixture, the fixture fixing plate is perpendicular to the fixture base plate and parallel to the top block.

[0017] As described above, a tooling for machining riveting holes in a semi-circular block includes a clamping cylinder comprising a cylinder body and a cylinder push rod.

[0018] The cylinder push rod is coaxially connected to the drive shaft of the cylinder body, and the push block is fixed on the cylinder push rod.

[0019] As described above, in a semi-circular block riveting hole machining fixture, the cylinder push rod and the push block are fixedly connected by threads, which facilitates the replacement of the push block.

[0020] The above technical solution is only one feasible technical solution of this utility model. The protection scope of this utility model is not limited to this. Those skilled in the art can reasonably adjust the specific design according to actual needs.

[0021] Compared with the prior art, the above-mentioned utility model has the following advantages or beneficial effects:

The semi-circular block is placed in the fixture, the fixture is placed in front of the top block, and the fixture is tightened by the clamping cylinder. With the cooperation of the fixture fixing plate, the fixture, i.e. the semi-circular block, can be fixed. The riveting hole of the semi-circular block in the fixture can be quickly positioned by the riveting hole alignment hole on the fixture that matches the riveting hole of the semi-circular block. The drill bit can be processed by passing through the riveting hole alignment hole. Compared with the traditional method, the operation difficulty is low and the processing efficiency is high.

[0023] (2) The tooling for processing the riveting holes of the semi-circular arc block of this utility model can fix multiple semi-circular arc blocks (two semi-circular arc blocks arranged opposite each other are a group, and multiple groups of semi-circular arc blocks can be fixed at the same time), reducing the clamping frequency of the semi-circular arc blocks, improving processing efficiency, and has great application prospects.

Detailed Implementation

[0033] The structure of this utility model will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the utility model.

[0034] Example 1

[0035] A tooling for machining riveting holes in a semi-circular block, such as Figures 4-7 As shown, it includes tooling base plate 4;

[0036] The clamping cylinder 5 is fixed to the tooling base plate 4 by the cylinder fixing block 9. The clamping cylinder 5 includes a cylinder body 51 and a cylinder push rod 52. The cylinder push rod 52 is coaxially connected to the drive shaft of the cylinder body 51, and the top block 6 is fixed to the cylinder push rod 52 by threads. The tooling base plate 4 also has a clamp 8 for arranging the semi-circular block 1, and the clamp 8 is located on the side of the top block 6 away from the clamping cylinder 5. The clamp 8 is provided with a clamp fixing plate 7 fixed to the tooling base plate 4 on the side away from the top block 6. The clamp fixing plate 7 is perpendicular to the tooling base plate 4 and parallel to the top block 6.

[0037] The fixture 8 has a semi-circular block arrangement groove in the middle for accommodating two oppositely arranged semi-circular blocks 1 and for limiting the two oppositely arranged semi-circular blocks 1. The outer wall of the fixture 8 has a riveting hole alignment hole 81 that matches the riveting hole of the semi-circular block. The outer wall of the fixture with the riveting hole alignment hole 81 is flat. The four outer walls of the fixture 8 have riveting hole alignment holes 81 and the four outer walls form a square structure. One outer wall of the fixture has multiple riveting hole alignment holes 81 arranged in a row.

[0038] Specifically, the fixture can simultaneously load 10 (5 sets) semi-circular blocks.

[0039] The operation for machining the riveting holes of the semi-circular block using the aforementioned tooling is as follows:

[0040] Stack 10 semi-circular blocks in pairs and place them into the semi-circular block arrangement slot of the fixture. Place the fixture next to the fixture fixing plate, turn on the cylinder switch, and make the top block press against the semi-circular blocks to fix them in the semi-circular block arrangement slot. The drilling machine can then process the riveting holes on one side by passing through the riveting hole alignment hole.

[0041] Release the cylinder, rotate the fixture so that the unprocessed surface of the fixture is on the top surface, then turn on the cylinder switch so that the top block presses against the semi-circular block and fixes it in the semi-circular block arrangement slot. The drill press passes through the riveting hole and aligns the hole to process the riveting hole on one side. Repeat the above operation until the riveting holes of 10 (5 sets) semi-circular blocks are processed. Five elastic components can be assembled and riveted, which improves efficiency and reduces the difficulty of processing operation. Ordinary workers (with low requirements for processing skills) can complete the operation.

[0042] In summary, this application provides a fixture for machining riveting holes in a semi-circular arc block. The fixture has a reasonable structural design. The semi-circular arc block is placed inside a jig, which is then positioned in front of the top block. A clamping cylinder tightens the jig, and with the cooperation of the jig fixing plate, the jig, i.e., the semi-circular arc block, is fixed. The riveting holes of the semi-circular arc block inside the jig are quickly positioned using the riveting hole alignment holes on the jig that match the riveting holes on the semi-circular arc block. A drill bit passes through the riveting hole alignment holes to machine the riveting holes of the semi-circular arc block. Compared to traditional methods, this method is easier to operate and has higher processing efficiency. The fixture can simultaneously fix multiple semi-circular arc blocks (two oppositely arranged semi-circular arc blocks form a group, and multiple groups of semi-circular arc blocks can be fixed), reducing the frequency of clamping the semi-circular arc blocks and improving processing efficiency, making it highly promising for application.
