Description

Technical Field

[0001] This utility model relates to the field of cutting tool manufacturing technology, and in particular to a fixture for manufacturing specific PCD cutting inserts. Background Technology

[0002] PCD cutting tool batch processing fixtures are specialized tooling equipment used in the mass production of polycrystalline diamond (PCD) cutting tools to achieve workpiece positioning, clamping, and auxiliary processing. Their core function is to improve batch production efficiency and reduce human error while ensuring the machining accuracy of PCD cutting tools (such as dimensions, angles, and surface quality).

[0003] Current cutting tool fixtures typically consist of a tool holder or tool shank and a mounting slot for mounting the cutting tool. In mass production, frequent machine stops are required to replace the cutting tool or the entire tool holder, resulting in low machine tool utilization. Furthermore, after each cutting tool replacement or tool holder reinstallation, tool recalibration is necessary to ensure accurate tool tip position. This process is prone to human error and risks of repeated positioning, which may lead to dimensional deviations between batches. If the entire tool holder (not just the cutting tool) is replaced, the overhang length of the tool may change slightly, affecting tool rigidity and machining stability, and consequently, accuracy. Utility Model Content

[0004] To solve the above-mentioned technical problems and achieve the above-mentioned technical effects, this utility model is implemented through the following technical solution: The technical solution of this utility model is: a specific PCD cutting tool manufacturing fixture, including a clamping plate and a connecting seat integrally formed from front to back. A limiting cavity is opened at the front end of the clamping plate, and a limiting block is set at the center of the limiting cavity. An installation groove is opened at the front end of the clamping plate and outside the limiting cavity. Multiple installation grooves are arranged around the limiting block at intervals. A pressure plate movable groove is opened on one side of the center of each installation groove. A connecting hole is opened at the end of the pressure plate movable groove away from the installation groove. A connecting block is fixedly installed inside the installation groove. An installation hole communicating with the connecting hole is opened through the back of the clamping plate.

[0005] Furthermore, the diameter of the mounting hole is smaller than the diameter of the connecting hole.

[0006] Furthermore, multiple connecting blocks are spaced apart along the length of the mounting groove, and the multiple connecting blocks are arranged in a straight line from front to back in the middle of the mounting groove.

[0007] Furthermore, the connecting hole is circular, and the depth of the connecting hole is the same as the depth of the mounting groove.

[0008] Furthermore, each of the mounting slots is detachably provided with a blade, one end of which extends into the inner cavity of the limiting cavity, the other end of which extends into the outside of the clamping plate, and the blade is provided with a blade head on the outside of the clamping plate.

[0009] Furthermore, the back of the blade is provided with a connecting groove that is compatible with the connecting block.

[0010] Furthermore, the connecting seat and the limiting block are on the same horizontal axis.

[0011] Furthermore, the length of the connecting seat is greater than the thickness of the clamping plate.

[0012] The beneficial technical effects of this utility model are: (1) A specific PCD cutting insert manufacturing fixture, by setting multiple mounting slots, allows the clamping plate to clamp multiple cutting inserts simultaneously. Compared with a fixture that installs a single cutting insert, this fixture can improve production capacity through multi-station synchronous processing. At the same time, by changing the limit blocks of the corresponding size, it can be adapted to limit the cutting inserts of different lengths, thereby improving the clamping accuracy. In mass production, there is no need to frequently stop the machine to change the cutting inserts or the entire tool holder, which increases the utilization rate of the machine tool and reduces the number of times the tool is re-set. This significantly reduces problems such as dimensional deviations and cutting edge defects in the cutting insert processing process.

[0013] (2) A specific PCD cutting tool manufacturing fixture, which can install hook-shaped pressure plates of different specifications by setting a connecting hole on one side next to the mounting slot. When the fixture is fixing cutting tools of different sizes, the matching hook-shaped pressure plate can be installed inside the mounting hole. Then the other end of the hook-shaped pressure plate fixes the cutting tool in the mounting slot, so that the fixture can clamp cutting tools of different lengths, thereby improving the versatility of the fixture.

[0016] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0017] See appendix Figure 1-4 As shown, a specific PCD insert manufacturing fixture includes a clamping plate 1 and a connecting seat 2 integrally formed from front to back. The length of the connecting seat 2 is greater than the thickness of the clamping plate 1, and the connecting seat 2 and the limiting block 7 are on the same horizontal axis.

[0018] A limiting cavity 6 is provided at the front end of the clamping plate 1, and a limiting block 7 is provided at the center of the limiting cavity 6. The limiting block 7 can limit one end of the cutting tool 3 to ensure that the overhang length of the cutting tool 3 is uniform, and avoid the problem that the overhang length of the cutting tool will change slightly due to the replacement of the cutting tool clamp, which will affect the accuracy of the subsequent cutting tool.

[0019] A mounting groove 4 is provided at the front end of the clamping plate 1 and outside the limiting cavity 6. Multiple mounting grooves 4 are arranged around the limiting block 7 at intervals. A pressure plate movable groove 42 is provided on one side of the center of each mounting groove 4. A connecting hole 41 is provided at the end of the pressure plate movable groove 42 away from the mounting groove 4. A connecting block 43 is fixedly installed inside the mounting groove 4. A blade 3 is detachably installed inside each mounting groove 4. One end of the blade 3 extends into the inner cavity of the limiting cavity 6, and the other end of the blade 3 extends into the outside of the clamping plate 1. A blade head 31 is provided on the outside of the clamping plate 1. A connecting groove that matches the connecting block 43 is provided on the back of the blade 3. Multiple connecting blocks 43 are arranged at intervals along the length of the mounting groove 4. Multiple connecting blocks 43 are arranged in a straight line from front to back in the middle of the mounting groove 4. By setting multiple connecting blocks 43, after the blade 3 is installed inside the mounting groove 4, the connecting blocks 43 can assist in fixing the blade 3 and prevent the blade 3 from moving horizontally inside the inner cavity of the mounting groove 4.

[0020] By setting multiple mounting slots 4, the clamping plate 1 can simultaneously hold multiple cutting inserts 3. Compared with a fixture that installs a single cutting insert, the number of mounting slots 4 in this fixture can be customized from 4 to 20 according to requirements, realizing multi-station synchronous processing and increasing the production capacity by 3 to 5 times. In addition to increasing the production capacity, by replacing the corresponding size limit block 7, it can be adapted to limit the cutting tools of different lengths, improving the clamping accuracy. Compared with a single clamping limit, unified limit can save more than 70% of the time. In mass production, there is no need to frequently stop the machine to change cutting inserts or the entire tool holder, which increases the utilization rate of the machine tool and reduces the number of times the tool is re-set. This greatly reduces problems such as dimensional deviation and cutting edge defects during the cutting insert 3 processing.

[0021] The back of the clamping plate 1 has a through mounting hole 5 that communicates with the connecting hole 41. The diameter of the mounting hole 5 is smaller than the diameter of the connecting hole 41. The connecting hole 41 is circular, and its depth is the same as the depth of the mounting groove 4. The circular shape of the connecting hole 41 allows the mounting seat of the hook-shaped pressure plate to be locked inside the connecting hole 41, and the mounting part of the hook-shaped pressure plate can be inserted into the inner cavity of the mounting hole 5 for fixation. This allows the clamping part of the hook-shaped pressure plate to press and fix the cutting insert 3. The hook-shaped pressure plate is also detachable. When fixing cutting inserts 3 of different sizes, the appropriate hook-shaped pressure plate can be installed inside the mounting hole 5, and then the other end of the hook-shaped pressure plate fixes the cutting insert 3 in the mounting groove 4. This allows the clamp to clamp cutting inserts 3 of different lengths, improving the versatility of the clamp.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
