AI Technical Summary
Existing technologies make it difficult to ensure that two drilling operations are on the same straight line when drilling silicon carbide rollers, resulting in high scrap rates and low efficiency.
The clamping assembly with a symmetrical structure clamps the silicon carbide roller. By flipping the clamping assembly, the positions of the two punching operations are ensured to be on the same straight line. Precise positioning is achieved by utilizing the symmetry of the clamping assembly and the limiting function of the positioning block.
This improved the machining accuracy and efficiency of drilling silicon carbide rollers and reduced the scrap rate.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of silicon carbide block detection technology, specifically relating to a silicon carbide roller drilling tool. Background Technology
[0002] When drilling silicon carbide rollers, especially irregularly shaped ones such as waist-shaped or elliptical ones, high positioning accuracy is required. Due to the high hardness of silicon carbide rollers, drilling tools cannot completely penetrate them, so it is necessary to drill a hole on each side of the roller. This requires ensuring that the positioning of the silicon carbide roller remains unchanged after flipping, so that the axes of the two drillings are on the same straight line.
[0003] In the existing technology, when punching holes in silicon carbide rollers, it is difficult to ensure that the two punches are on the same straight line, which can easily lead to misalignment of the holes, resulting in a high scrap rate and low processing efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a drilling fixture for silicon carbide rollers, which solves the problem in the prior art that it is difficult to ensure that two holes are drilled on the same straight line when drilling silicon carbide rollers.
[0005] Therefore, this utility model provides a silicon carbide roller drilling fixture, including a base plate and a clamping assembly. The clamping assembly is used to clamp the silicon carbide roller. The clamping assembly has a symmetrical structure and the top or bottom surface of the clamping assembly is detachably connected to the base plate.
[0006] Preferably, the clamping assembly includes a first clamping plate and a second clamping plate, which are fixedly connected.
[0007] Preferably, the first clamping plate and the second clamping plate have the same shape, and the first clamping plate and the second clamping plate are arranged symmetrically.
[0008] Preferably, the first clamping plate and the second clamping plate are fixedly connected by bolts.
[0009] Preferably, the first clamping plate is provided with a first V-groove, and the second clamping plate is provided with a second V-groove, with the first V-groove being arranged opposite to each other.
[0010] Preferably, the first V-groove and the second V-groove have the same shape.
[0011] Preferably, multiple first V-grooves are arranged in parallel.
[0012] Preferably, the first clamping plate or the second clamping plate is connected to the base plate by bolts.
[0013] Preferably, multiple clamping assemblies are provided along the horizontal direction.
[0014] Preferably, a positioning block is fixedly installed on the base plate, the positioning block is on one side of the clamping assembly, and the positioning block is used to limit the axial movement of the silicon carbide roller.
[0015] Beneficial effects:
[0016] This utility model provides a silicon carbide roller drilling fixture. The silicon carbide roller is clamped by a clamping assembly with a symmetrical structure. After drilling a hole on one side of the silicon carbide roller, the clamping assembly is flipped over and the hole is drilled again. Since the clamping assembly is symmetrical, the height of the clamping assembly is the same after flipping, which facilitates the positioning of the hole and ensures that the two drilling positions are on the same straight line.

[0020] The following detailed description of preferred embodiments of the present invention, along with the included examples, will make the content of the present invention more readily understood. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. In case of any conflict, the definitions in this specification shall prevail.
[0021] Example 1:
[0022] Provided such as Figure 1 The illustrated silicon carbide roller drilling fixture includes a base plate 1 and a clamping assembly 2. The clamping assembly 2 is used to clamp the silicon carbide roller 4. The clamping assembly 2 has a symmetrical structure, and its top or bottom surface is detachably connected to the base plate 1. The base plate 1 is used to fix the fixture on the drilling machine. A coordinate system is established with the base plate 1 to keep the drilling position of the drill bit of the drilling machine relative to the base plate 1 constant, thus ensuring positioning accuracy.
[0023] The clamping assembly 2 includes a first clamping plate 21 and a second clamping plate 22, which are fixedly connected. The first clamping plate 21 and the second clamping plate 22 have the same shape and are symmetrically arranged. The first clamping plate 21 and the second clamping plate 22 are fixedly connected by bolts.
[0024] The first clamping plate 21 is provided with a first V-groove 23, and the second clamping plate 22 is provided with a second V-groove 24. The first V-grooves 23 are arranged opposite to each other. The first V-grooves 23 and the second V-grooves 24 have the same shape. Multiple first V-grooves 23 are arranged in parallel. The first V-grooves and the second V-grooves clamp and limit the silicon carbide roller 4. Multiple first V-grooves and second V-grooves can process multiple silicon carbide rollers 4 at the same time, improving processing efficiency.
[0025] The first clamping plate 21 or the second clamping plate 22 is connected to the base plate 1 by bolts. The bolts allow for quick loading and unloading of the first clamping plate 21 or the second clamping plate 22.
[0026] Multiple clamping assemblies 2 are arranged horizontally. The multiple clamping assemblies 2 limit the movement of the silicon carbide roller 4.
[0027] A positioning block 3 is fixedly installed on the base plate 1. The positioning block 3 is located on one side of the clamping assembly 2 and is used to limit the axial movement of the silicon carbide roller 4. The positioning block 3 positions the silicon carbide roller 4 axially, thereby improving the positioning accuracy of the silicon carbide roller 4.
[0028] Working principle: The base plate 1 is fixed on the drilling machine. The silicon carbide roller 4 is clamped and limited by the first clamping plate 21 and the second clamping plate 22. Then, the first clamping plate 21 is fixed on the base plate 1, and the axial direction of the silicon carbide roller 4 is limited by the positioning block 3. The drilling machine drills holes in the silicon carbide roller 4. Then, the clamping assembly 2 and the silicon carbide roller 4 are disassembled as a whole. After flipping, the second clamping plate 22 is fixed on the base plate 1. Similarly, the silicon carbide roller 4 is limited by the positioning block 3, and the drilling machine drills holes in the silicon carbide roller 4. Since the first clamping plate 21 and the second clamping plate 22 are the same height and multiple V-grooves are evenly distributed in parallel, the height and horizontal position of the silicon carbide roller 4 are the same after flipping. With the help of the positioning block 3, the axial position is the same, thus ensuring that the drilling positions are the same in both cases and ensuring processing accuracy.
[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
