Description

Technical Field

[0001] The present application relates to the field of auxiliary processing technology, and in particular to a common processing tool for disc-shaped parts. Background Art

[0002] Disc-shaped parts, as the name suggests, are roughly circular or disc-shaped, with a small axial dimension, a large radial diameter, and a rotational axis as the axis of symmetry. Therefore, disc-shaped parts are widely used in the machinery industry, construction and engineering, and mold and die industries.

[0003] Currently, disc-shaped parts often require fixture clamping and positioning before machining threaded holes and countersunk holes. However, existing fixtures lack sufficient clamping force, which can cause disc-shaped parts to move during machining due to cutting forces or vibrations, leading to machining failures. Utility Model Content

[0004] In order to improve the problem of insufficient clamping force of existing tooling, which leads to processing failure, the present application provides a common processing tooling for disc-shaped parts.

[0005] This application provides a common processing tool for disc-shaped parts, which adopts the following technical solutions:

[0006] A common processing tool for disc-shaped parts, comprising a base plate, positioning blocks spaced apart on the base plate, a pressing assembly disposed in the middle of the base plate, and locking units spaced apart on the base plate;

[0007] A positioning slot is provided on the top of the positioning block;

[0008] The clamping assembly includes a first clamping plate located above the positioning block, a locking bolt threadedly connected to the bottom plate, the rod of the locking bolt passing through the first clamping plate, and the first clamping plate is used to clamp the workpiece to be processed;

[0009] The locking unit includes a second pressure plate located between adjacent locking blocks and a compression bolt threadedly connected to the base plate. The rod of the compression bolt is passed through the second pressure plate. The second pressure plate is located above the positioning block and is used to press the parts to be processed.

[0010] Preferably, the bottom plate has a rectangular structure, and there are multiple second pressing plates, which are distributed at intervals along the circumference of the bottom plate.

[0011] Preferably, the positioning slot has a stepped structure.

[0012] Preferably, both ends of the second pressing plate are located directly above adjacent positioning blocks.

[0013] Preferably, there are multiple positioning blocks, and they are distributed in a matrix.

[0014] Preferably, the bottom plate is provided with a first guide rod passing through the first pressure plate, and the first pressure plate is connected to the first guide rod by sliding up and down; the bottom plate is provided with a second guide rod passing through the second pressure plate, and the second pressure plate is connected to the second guide rod by sliding up and down.

[0015] Preferably, the base plate is provided with a handle.

[0016] In summary, the beneficial effects of this application are:

[0017] 1. Before processing, the disc-shaped part to be processed is placed in the positioning slot, and then pressed by the first and second pressing plates. At this time, the disc-shaped part is pressed by the first pressing plate and the two second pressing plates at the same time, forming three pressing points on the part, which maintains stability during the processing and reduces movement or deformation caused by vibration or external force. At the same time, the three-point pressing can more evenly distribute the pressing force, avoid deformation caused by local stress concentration, make the tooling clamping of this application reliable, and reduce the processing defect rate;

[0022] The following is in conjunction with the instructions Figure 1 This application is described in further detail.

[0023] The present invention discloses a common tooling system for processing disc-shaped parts, comprising a base plate 1, four positioning blocks 2 spaced apart from the base plate 1, a clamping assembly 3 located in the middle of the base plate 1, and locking units 4 spaced apart from the base plate 1. Prior to processing, the clamping assembly 3 and locking units 4 are used to apply three-point clamping to the disc-shaped part for stable clamping.

[0024] Specifically, the base plate 1 is generally a cube, with handles 11 mounted on its two broad sides. Four positioning blocks 2 are arranged in a matrix on the top of the base plate 1. Positioning slots 21 are defined at the top of these blocks for inserting and positioning disc-shaped components. These slots 21 are stepped, providing multi-layered positioning for secure clamping.

[0025] The clamping assembly 3 comprises a first pressure plate 31 positioned above the positioning block 2 and a locking bolt 32 threadedly connected to the base plate 1. The rod of the locking bolt 32 passes through the first pressure plate 31, which is used to clamp the disc-shaped part to be machined. The first pressure plate 31 is also generally cubic in structure, with arcuate surfaces on all four sides and four openings spaced apart at intervals through its top.

[0026] Furthermore, two first guide rods 33 penetrating the first pressing plate 31 are vertically fixed to the top of the bottom plate 1 , and the first pressing plate 31 is connected to the first guide rods 33 in an up-and-down sliding manner.

[0027] In the embodiment of the present application, four locking units 4 are used, and the four locking units 4 are respectively located at the top of the base plate 1 and close to the side wall of the base plate 1. The locking unit 4 includes a second pressure plate 41 located between adjacent locking blocks, and a compression bolt 42 threadedly connected to the base plate 1, and the rod of the compression bolt 42 is passed through the second pressure plate 41. The second pressure plate 41 is located above the positioning block 2, and the two ends of the second pressure plate 41 are respectively located directly above the adjacent positioning block 2; the second pressure plate 41 is used to press the disc-shaped part to be processed. There are four second pressure plates 41 in total, and they are spaced apart along the circumference of the base plate 1.

[0028] Furthermore, two second guide rods 43 penetrating the second pressing plate 41 are vertically fixed to the top of the bottom plate 1 , and the second pressing plate 41 is connected to the second guide rods 43 in an up-and-down sliding manner.

[0029] The implementation principle of a common processing tool for disc-shaped parts in the embodiment of the present application is as follows:

[0030] Before machining, the disc-shaped part to be machined is placed in the positioning slot 21. The locking bolt 32 is used to drive the first pressure plate 31 downward to press the disc-shaped part. At the same time, the pressing bolt 42 is rotated, causing the second pressure plate 41 to move downward to press the top of the disc-shaped part. At this time, the disc-shaped part is simultaneously pressed by the first pressure plate 31 and the two second pressure plates 41, forming three pressing points on the disc-shaped part. The three-point pressing can more evenly distribute the pressing force, avoid deformation caused by local stress concentration, and maintain stability during machining, reducing movement or deformation caused by vibration or external forces. This ensures reliable clamping and reduces the rate of processing defects, thereby improving the problem of insufficient clamping force in existing tooling, which leads to processing failures.

[0031] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
