Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a clamping device for turning and drilling tools. Background Technology

[0002] In the field of machining, turning and drilling are among the most commonly used machining processes. CNC lathes are one of the most commonly used pieces of equipment. By clamping the cutting tool on a tool holder, the lathe drives the workpiece to rotate. While the workpiece rotates and the tool feeds, the cutting edge of the cutting tool contacts the workpiece surface, generating cutting force to remove excess metal material from the workpiece, so that the workpiece gradually reaches the required shape and size. Therefore, the performance of the tool holder will affect the quality of workpiece machining.

[0003] Most lathe tool holders are quick-change tool holders, which use the pressure generated by tightening bolts to press the tool firmly onto the tool holder, thereby fixing the tool. Under prolonged pressure, the bolts can easily damage the tool shank. At the same time, because the tool holder is an open design, the tool can easily pop out when the bolts loosen, which can not only damage the tool but also create a safety hazard. Utility Model Content

[0004] The purpose of this utility model is to provide a turning and drilling tool clamping device that facilitates the application of pressure from all directions of the tool, thereby improving the clamping effect of the tool. At the same time, it can wrap the tool shank to restrict the position of the tool, prevent the tool from popping out due to loose bolts, and reduce safety hazards.

[0005] To achieve the above objectives, a turning and drilling tool clamping device is provided, comprising: a base plate, a support block fixedly connected to the upper surface of the base plate, a top plate fixedly connected to the upper surface of the support block, bolts threadedly connected to both sides of the base plate, a lower pressure plate rotatably connected to the bottom of the bolts, clearance grooves provided at the bottom of both sides of the support block, a first guide groove and a second guide groove provided on the upper surface of the base plate, a first guide block slidably connected to the inner surface of the first guide groove, a clamping seat fixedly connected to the upper surface of the first guide block, a sliding groove provided on the upper surface of the clamping seat, a guide rod fixedly connected to the inner surface of the sliding groove, a slider slidably connected to the outer surface of the guide rod, a clamping plate fixedly connected to the upper surface of the slider, and a clamping spring sleeved on the outer surface of the guide rod;

The clamping seat 10 is adapted to the second guide block 26, which is fixedly connected to the lower surface of the clamping seat 10. The outer surface of the second guide block 26 is slidably connected to the second guide groove 8, which facilitates the movement of the clamping seat 10 and improves the stability of the movement of the clamping seat 10. The upper surface of the clamping seat 10 is provided with a slide groove 11, and the inner surface of the slide groove 11 is fixedly connected to a guide rod 12, which guides the movement of the slider 13 and restricts the position of the clamping spring 15 to prevent the clamping spring 15 from deforming and affecting the clamping effect. The outer surface of the guide rod 12 is slidably connected to the slider 13, and the outer surface of the slider 13 is slidably connected to the slide groove 11. The upper surface of the slider 13 is fixedly connected to a clamping plate 14, and the outer surface of the guide rod 12 is sleeved with a clamping spring 15. One end of the clamping spring 15 is fixedly connected to the slider 13, and the end of the clamping spring 15 away from the slider 13 is fixedly connected to the slide groove 11.

[0029] A rack 16 is fixedly connected to the lower surface of the first guide block 9. A gear 17 is meshed with the lower surface of the rack 16. A drive shaft 18 is fixedly connected to the inner surface of the gear 17. A protective box 19 is fixedly connected to the side wall of the base plate 1. The outer surface of the drive shaft 18 is rotatably connected to the protective box 19. A check spring 20 is fixedly connected to the inner side wall of the protective box 19 to ensure that the first check disc 21 and the second check disc 23 are always in contact. The end of the check spring 20 away from the protective box 19 is fixedly connected to the first check disc 21. The inner surface of the first check disc 21 is slidably connected to the drive shaft 18. A lever 22 is fixedly connected to the outer surface of the drive shaft 18. The outer surface of the lever 22 is slidably connected to the protective box 19, which facilitates the movement of the first anti-reverse disc 21 and its separation from the second anti-reverse disc 23 by the lever 22, thereby removing the restriction on the reverse rotation of the drive shaft 18. The second anti-reverse disc 23 is fixedly connected to the outer surface of the drive shaft 18. Anti-reverse teeth 24 are provided on the side surfaces of the second anti-reverse disc 23 and the first anti-reverse disc 21. The anti-reverse teeth 24 on the second anti-reverse disc 23 and the first anti-reverse disc 21 are opposite in direction, which facilitates their interlocking. The anti-reverse teeth 24 interlock with each other. The outer surface of the second anti-reverse disc 23 is slidably connected to the protective box 19.

[0030] Working principle: The tool is placed between the clamping seat 10 and the clamping plate 14. The spring force of the clamping spring 15 drives the slider 13 to move, so that the clamping plate 14 pre-clamps the tool. The drive shaft 18 is rotated to drive the gear 17 to rotate. Through the meshing connection between the gear 17 and the rack 16, the first guide block 9 moves inward along the first guide groove 7. During the movement, the clamping seat 10 will enter the clearance groove 6, so that the clamping plate 14 contacts the side wall of the support block 2. The drive shaft 18 continues to rotate, so that the clamping seat 10 continues to move into the clearance groove 6. The tool is fixed by the combined action of the pressure of the support block 2 on the clamping plate 14 and the clamping seat 10. During the rotation of the drive shaft 18, the anti-reverse spring 20 acts as a stop spring. The second check plate 23 is kept in contact with the first check plate 21. The action between the check teeth 24 prevents the drive shaft 18 from reversing, thus ensuring the stability of the tool clamping. Rotating the bolt 4 drives the lower pressure plate 5 to move downward to restrict the upper surface of the tool, thereby restricting the tool in all directions and improving the stability of the tool clamping. When the tool needs to be replaced, the toggle block 22 moves the first check plate 21 to separate the first check plate 21 from the second check plate 23, thereby removing the fixation of the drive shaft 18. Rotating the drive shaft 18 in the opposite direction causes the clamping seat 10 to move outward. During the movement, the clamping spring 15 can drive the clamping plate 14 to always clamp the tool, preventing the tool from falling.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
