Technical Field
[0001] This utility model relates to the technical field of cemented carbide tool machining, and in particular to a cemented carbide tool head turning fixing device. Background Technology
[0002] Cemented carbide is an alloy material made from hard compounds of refractory metals and a binder metal through powder metallurgy. It is widely used as a cutting tool material, such as turning tools, end mills, planing tools, drills, and boring tools, for cutting cast iron, non-ferrous metals, plastics, synthetic fibers, graphite, glass, stone, and ordinary steel. It can also be used to cut difficult-to-machine materials such as heat-resistant steel, stainless steel, high-manganese steel, and tool steel. Cemented carbide tools require grinding during machining, and appropriate clamping devices are needed for holding and securing them in place. Existing technology publication number CN214444787U discloses a clamping and fixing device for machining cemented carbide tools, including an operating table, a clamping cylinder, a connecting block, a rotating plate, and a fixing plate. The clamping cylinder is rotatably connected to the center of the upper end face of the operating table. A circular groove adapted to the clamping cylinder is formed on the upper end face of the operating table. A first fastening groove and a second fastening groove are symmetrically formed at one end of the clamping cylinder, dividing one end of the clamping cylinder into an upper clamping plate and a lower clamping plate. A connecting block is constructed at the top of the upper clamping plate, and a threaded post is internally threaded into the connecting block. One end of the threaded post penetrates the clamping cylinder and extends into it. A fastening block is installed at the end of the extended portion of the threaded post. The other end of the clamping cylinder extends out of the side of the operating table. However, this device cannot achieve efficient and rapid replacement of the clamping head, making it inconvenient for the user to change the clamping head according to the shape of the clamped tool.

[0004] This utility model discloses a carbide cutting tool head fixing device for turning, comprising a base, a mounting plate, an insert component, a locking component, and a clamping component. The bottom of the mounting plate is mounted on the top of the base via the insert component. A locking component is installed between the mounting plate and the base, and a locking component is also installed on the top of the mounting plate. The mounting plate is mounted on the base via the insert component and fixed by the locking component.

[0005] Preferably, the insertion component includes an insertion post, two limiting blocks, and two long screws. The top of the base has an insertion slot, and the insertion slot has a limiting groove. The bottom of the mounting plate has an insertion post, and the limiting blocks are symmetrically installed on the outer wall of the insertion post. The bottom of the base and the limiting blocks have corresponding screw holes. The insertion post at the bottom of the mounting plate is inserted into the insertion slot, the mounting plate is rotated to allow the limiting blocks to enter the limiting grooves, and the long screws are rotated to enter the screw holes, connecting the limiting blocks and the base. The user can change the clamping head with different clamping surface shapes according to the shape of the clamped tool, improving practicality.

This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.
[0019] like Figures 1 to 5As shown, the base 1 has an insertion slot at its top, and a limit slot is provided in the insertion slot. A post 3 is installed at the bottom of the mounting plate 2, and limit blocks 4 are symmetrically installed on the outer wall of the post 3. Screw holes are correspondingly provided on the bottom of the base 1 and on the limit blocks 4. Fixing blocks 14 are installed on the left and right sides of the top of the base 1, and connecting blocks 15 are installed on the left and right sides of the mounting plate 2. Bolts 16 are screwed onto the fixing blocks 14, and threaded holes are provided on the connecting blocks 15. Clamping slots are provided at the left and right ends of the top of the mounting plate 2, and threaded rods 8 are rotatably installed in the clamping slots. A drive slot is provided in the middle of the top of the mounting plate 2, and a drive bevel gear 9 is installed at one end of the threaded rod 8 through the drive slot. A rotating rod 6 is rotatably installed on the mounting plate 2. A bevel gear 7 is installed at the front end of the mounting plate 2 and the rear end of the rotating rod 6. The bevel gear 7 meshes with the drive bevel gear 9. An adjusting nut is provided at the front end of the rotating rod 6. The clamping slider 10 is slidably installed in the clamping groove and screwed onto the outer wall of the threaded rod 8. A clamping plate 11 is installed on the top of the clamping slider 10. The clamping plate 11 is slidably located on the top of the mounting plate 2. The top of the mounting plate 2 has symmetrical limit guide grooves on the left and right sides about the clamping groove. Limit guide blocks 12 are symmetrically installed at the bottom of the clamping plate 11. The limit guide blocks 12 are slidably installed in the limit guide grooves. A threaded hole is provided in the middle of the clamping plate 11. The tightening screw 13 can be screwed into the threaded hole. An anti-slip pressure pad is provided on the inner wall of the clamping plate 11.
[0020] Insert the bottom insert 3 of the mounting plate 2 into the insertion slot, rotate the mounting plate 2 to allow the limiting block 4 to enter the limiting slot, and rotate the long screw 5 into the screw hole to connect the limiting block 4 and the base 1. The user can change the clamping head with different clamping surface shapes according to the shape of the clamped tool to improve practicality. After the mounting plate 2 is rotated and installed, the fixing block 14 contacts the connecting block 15. Rotate the bolt 16 into the threaded hole to lock and fix the fixing block 14 and the connecting block 15 to ensure stability. The rotating rod 6 is driven to rotate by adjusting the nut. The rotating rod 6 passes through the cone Gear 7 and drive bevel gear 9 drive threaded rod 8 to rotate, causing clamping slider 10 to slide in clamping groove, and clamping plate 11 to move above mounting plate 2, slowly squeezing the tool tightly. The movement of clamping plate 11 drives limiting guide block 12 to slide in limiting guide groove, guiding and limiting it, improving the stability during clamping and fixing. According to the usage requirements, tightening screw 13 is screwed into threaded hole, and the tool is clamped by tightening screw 13, improving practicality. Anti-slip pressure pad can ensure the friction between clamping plate 11 and tool, ensuring stability after clamping.
[0021] like Figures 1 to 5As shown, this utility model discloses an alloy tool head turning fixing device. During operation, the user can change the clamping head with different clamping surface shapes according to the shape of the tool being clamped. The bottom insert 3 of the mounting plate 2 is inserted into the insertion slot. Rotating the mounting plate 2 causes the limiting block 4 to enter the limiting slot. Rotating the long screw 5 into the screw hole connects the limiting block 4 and the base 1. After the mounting plate 2 is rotated and installed, the fixing block 14 contacts the connecting block 15. Rotating the bolt 16 into the threaded hole locks the fixing block 14 and the connecting block 15 in place. The adjusting nut drives the rotating rod 6 to rotate, which in turn drives the threaded rod 8 to rotate via the bevel gear 7 and the drive bevel gear 9. This causes the clamping slider 10 to slide in the clamping groove, allowing the clamping plate 11 to move above the mounting plate 2 and slowly compress the tool. The anti-slip pressure pad ensures the friction between the clamping plate 11 and the tool. The movement of the clamping plate 11 causes the limiting guide block 12 to slide in the limiting guide groove, which guides and limits its movement. According to the usage requirements, the tightening screw 13 is screwed into the threaded hole, and the tool is clamped by the tightening screw 13.
[0022] The above description is only a preferred embodiment of 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.
