Description

Technical Field

[0001] This invention relates to a loading and clamping assembly for a PCBN tool grinding machine and its usage method. Background Technology

[0002] PCBN cutting tools are man-made cubic boron nitride cutting tools. They can maintain high hardness even at high temperatures and are mainly used for machining iron parts. Their hardness is second only to diamond and far exceeds that of other materials. Therefore, it and diamond are collectively referred to as superhard materials.

[0003] Precision grinding is an essential step in the production of PCBN cutting tools. To ensure accuracy, one person usually operates one grinding machine. The machine needs to be loaded with materials, and the computer controls the grinding process. After grinding is completed, the material needs to be unloaded and reloaded.

[0004] However, this operating method has some problems: it wastes a lot of time on unloading and loading, making it unsuitable for mass production of cutting tools. Furthermore, workers are prone to human error due to fatigue when mechanically installing, grinding, and disassembling the cutting tools. Therefore, there is an urgent need for an automatic feeding, clamping, and unloading device. Summary of the Invention

A spring rod 12 is provided on the surface of the notch 10, and a pressing block 11 is provided on the spring rod 12. The pushing block 17 engages with the baffles 9 to engage the PCBN tool, and the pressing block 11 passes through the notch 10 to press and engage the PCBN tool. Under the action of the spring rod 12, the pressing block 11 can reset when the external force is lost.

[0033] Specifically, the compression end of the bearing chamber 1 is provided with a first electric push rod 13, and the power output end of the first electric push rod 13 is provided with a contact block 14 that can compress the compression block 11; the first electric push rod 13 drives the contact block 14 to compress the compression block 11.

[0034] Specifically, the output chamber 18 is provided with an output port 19 that can be connected to an external transmission device; the material is unloaded by connecting to the outside world through the output port 19.

[0038] A method for using a PCBN tool grinding machine loading and clamping assembly includes the following steps:

[0039] Step A, Installation: Insert the PCBN tool to be ground into the placement chamber 8 located on one side of the push chamber 15. Determine the installation position of the mounting rod 3 by the area to be ground of the tool. Install the entire device at the installation point by the mounting rod 3. Connect the output port 19 to the external transportation device through the guide slope.

[0040] Step B, loading: Take the fourth electric actuator 22 out of the storage bin 23, place the PCBN tool in it, align the area to be polished with the polishing area of ​​the grinder, and after filling, insert the fourth electric actuator 22 back into the storage bin 23.

[0041] Step C, Conveying and Clamping: During grinding, the fourth electric push rod 22 pushes the PCBN tool into the push chamber 15, and the second electric push rod 16 is activated. The second electric push rod 16 pushes the PCBN tool into the placement chamber 8 through the push block 17 and is limited by the two baffles 9. The first electric push rod 13 is activated, which drives the contact block 14 to squeeze the extrusion block 11, forcing it to clamp the PCBN tool.

[0042] Step D, Grinding and Unloading: The grinding machine performs fine grinding on the clamped PCBN tool. After grinding, the first electric push rod 13 is started in reverse. The first electric push rod 13 drives the contact block 14 to disengage from the surface of the extrusion block 11. Under the action of the spring rod 12, the extrusion block 11 is disengaged from the surface of the PCBN tool, and the restriction on it is removed. The second electric push rod 16 is retracted. During the retraction of the second electric push rod 16, the servo motor 5 is started. The servo motor 5 drives the gear 6 on its surface to rotate. Under the meshing action of the gear 6 and the tooth block 7, the rotating chamber 2 is rotated, and the placement chamber 8 containing the PCBN tool is rotated to the output chamber 18. Under the action of gravity, the PCBN tool falls to the output port 19. The third electric push rod 20 is started to push it out.

[0043] Step E: Repeat the above operations to complete the feeding, grinding, and unloading.

[0044] The PCBN tool grinding machine loading clamping assembly and its usage method of the present invention have the following advantages:

[0045] 1. When in use, the automatic feeding is achieved through the cooperation of the fourth electric push rod 22 and the second electric push rod 16. This eliminates the need for operators to frequently change raw materials. They only need to periodically fill the storage bin 23 with PCBN tools to be ground, which greatly increases the overall production efficiency and greatly reduces the problems caused by human error in manual mechanical operation, thereby reducing the overall grinding quality.

[0046] 2. When in use, the entire assembly is transported to the output chamber by rotating the rotating chamber 2 and using the gravity of the PCBN tool itself. It is then pushed out by the third electric push rod 20. The entire assembly can be unloaded without manual assistance, which greatly increases the overall production efficiency. The entire assembly can be widely used for PCBN tool grinding, loading, clamping and unloading.
