Description

Technical Field

[0001] The utility model relates to the technical field of bench vises, in particular to a bench vise used for processing diamond composite sheets. Background Art

[0002] Diamond composite sheets are made of diamond powder and cemented carbide substrates sintered under ultra-high pressure and high temperature conditions. They have the high hardness, high wear resistance and thermal conductivity of diamond, as well as the strength and impact toughness of cemented carbide. They are ideal materials for manufacturing cutting tools, drilling bits and other wear-resistant tools. A vise is a tool for clamping and fixing workpieces for processing. It is widely used. Diamond composite sheets generally need to be clamped and fixed by a vise during processing.

[0003] The existing device mainly clamps the workpiece by adjusting the jaws and fixing the jaws. The existing technology is similar to a bench vise. The structure with patent number CN219805944U includes two jaws, a fixed jaw and a movable jaw. A set of storage guard plate device is installed in each of the fixed jaw and the movable jaw. The storage guard plate device includes a fixed plate fixedly connected to the lower side walls of the two jaws, and an articulated frame is hinged on the fixed plate through a damping shaft. The guard plate is connected to the end of the articulated frame through the shaft rotation. A torsion spring is passed through the shaft, and one end of the torsion spring abuts on the articulated frame and the other end abuts on the guard plate. The guard plate is a wooden board or a polymer board. The bench vise can attach the two guard plates to the two jaws by rotating the articulated frame and the guard plate. When clamping the workpiece, due to the low hardness of the guard plate, no clamp marks will be generated on the workpiece, but the device still has areas that can be optimized.

[0004] The existing devices mainly clamp the side wall of the workpiece through the jaws, which makes it difficult for some devices to position and place diamond composite sheets of different diameters on the central axis of the jaws, resulting in that some jaws are difficult to accurately fit in the middle of the side of the diamond composite sheet. At the same time, some devices mainly fix the jaws on the inner wall of the clamp arm, making it difficult for some devices to drive the jaws and the diamond composite sheet to rotate within a limited position, resulting in that some devices are not convenient for cutting and other processing operations on the outer wall of the diamond composite sheet, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, a bench vise for processing diamond composite sheets is proposed. Utility Model Content

At the same time, some devices mainly fix the jaws on the inner side wall of the clamping arm, making it difficult for some devices to drive the jaws and the diamond composite sheet to rotate in a limited manner, resulting in inconvenience for some devices to perform machining operations such as cutting the outer wall of the diamond composite sheet.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 , an embodiment provided by the present invention:

[0023] A bench vice for processing diamond composite sheets, including a base 11. The left side of the top of the base 11 is slidably connected with an adjusting clamping arm 12. The right side of the top of the base 11 is fixedly connected with a fixed clamping arm 13. The upper right side of the fixed clamping arm 13 is fixedly connected with a transmission box 14. The middle of the top of the base 11 is slidably connected with a sliding frame 15. The top of the sliding frame 15 is fixedly connected with an adjusting box 16;

[0024] Inside the adjustment box 16, there is a positioning mechanism 2. The positioning mechanism 2 includes an adjustment worm 21. Both ends of the adjustment worm 21 are movably connected to the inner wall of the adjustment box 16. In the middle of the outer wall of the adjustment worm 21, there is a fixed connection of a second bevel gear 22. On both sides of the outer wall of the adjustment worm 21, there are engaged adjustment worm wheels 26. Inside the wall of the adjustment worm wheel 26, there is a fixed connection of a symmetric screw 27. Through this design, it is realized that the second bevel gear 22 drives the adjustment worm 21 to rotate with limited position, making the adjustment worm 21 drive the adjustment worm wheel 26 to rotate synchronously by meshing. Above the second bevel gear 22, there is an engaged first bevel gear 23. In the middle of the top of the first bevel gear 23, there is a fixed connection of a movable shaft 24. The top end of the movable shaft 24 passes through the adjustment box 16 and is fixedly connected with a first torsion cap 25. Through this design, it is realized that the first torsion cap 25 drives the movable shaft 24 and the first bevel gear 23 to rotate with limited position, making the first bevel gear 23 drive the second bevel gear 22 and the adjustment worm 21 to rotate with limited position by meshing. The top end of the symmetric screw 27 is movably connected to the top of the inner wall of the adjustment box 16. The bottom end of the symmetric screw 27 passes through the top plate of the sliding frame 15 and is movably connected to the bottom of the inner wall of the sliding frame 15. On both sides of the outer wall of the symmetric screw 27, there are movably connected adjustment nuts 28. Between the outer walls of the adjustment nuts 28, there is a fixed connection of a positioning clamp plate 29. Through this design, it is realized that the symmetric screw 27 drives the adjustment nuts 28 and the positioning clamp plate 29 to slide symmetrically, making the positioning clamp plate 29 position and place the circular diamond composite sheet on the central axis of the jaws.

[0025] Inside the transmission box 14, there is a rotating mechanism 3. The rotating mechanism 3 includes a transmission worm 31. The rear end of the transmission worm 31 is movably connected to the lower part of the inner wall of the transmission box 14. The front end of the transmission worm 31 passes through the transmission box 14 and is fixedly connected with a second torsion cap 32. Above the outer wall of the transmission worm 31, there is an engaged transmission worm wheel 33. Inside the wall of the transmission worm wheel 33, there is a fixed connection of a rotating shaft 34. Through this design, it is realized that the second torsion cap 32 drives the transmission worm 31 to rotate with limited position, and the transmission worm 31 drives the transmission worm wheel 33 and the rotating shaft 34 to rotate with limited position by meshing. The right end of the rotating shaft 34 is movably connected to the right side of the inner wall of the transmission box 14.

Through this design, it is realized that the rotating shaft 34 drives the fixed jaw 35, the diamond composite sheet and the sliding jaw 37 to rotate with limited position. At the same time, through the setting of the extension arm 36, the sliding frame 15 and the positioning mechanism 2 can be placed on the outer ring of the extension arm 36, effectively avoiding the positioning mechanism 2 from affecting the processing operation of the diamond composite sheet.

[0026] Working principle: When it is necessary to position and place the diamond composite sheet, first rotate the first torsion cap 25. The first torsion cap 25 drives the limited rotation of the movable shaft 24. The movable shaft 24 drives the synchronous rotation of the first bevel gear 23. The first bevel gear 23 meshes with and drives the rotation of the second bevel gear 22. The second bevel gear 22 drives the limited rotation of the adjusting worm 21. The adjusting worm 21 meshes with and drives the synchronous rotation of the adjusting worm gear 26. The adjusting worm gear 26 drives the limited rotation of the symmetric screw rod 27. The symmetric screw rod 27 drives the symmetric sliding of the adjusting nut sleeve 28. The adjusting nut sleeve 28 drives the synchronous sliding of the positioning clamping plate 29, so that the positioning clamping plate 29 positions and places the circular diamond composite sheet on the central axis of the jaw, realizing the positioning and placement operation of the diamond composite sheet.

[0027] When it is necessary to rotate the diamond composite sheet, first rotate the second torsion cap 32. The second torsion cap 32 drives the limited rotation of the transmission worm 31. The transmission worm 31 meshes with and drives the rotation of the transmission worm gear 33. The transmission worm gear 33 drives the limited rotation of the rotating shaft 34.
