Abstract
Description
Technical Field
[0001] This utility model relates to the field of machining technology, specifically to a clamping device for machining. Background Technology
[0002] Clamping devices in machining are used to fix and position workpieces. They ensure that the workpieces maintain a stable and precise position during machining, prevent movement or vibration under cutting forces, and ensure the accuracy of machining dimensions and shapes to meet design requirements. In the process of using a clamping device for machining, the parts to be machined are usually placed on the upper end of the placement table, and then the pneumatic clamps are used to fix the parts. Finally, the parts are machined. Existing machining clamping devices can fix parts using pneumatic clamps, but pneumatic clamps are cumbersome to install and maintain, generate a lot of noise during operation, and require a stable supply of compressed air. If the air source is unstable or the pressure is insufficient, it may affect the performance of the clamp and reduce the stability of the parts. Therefore, we propose a machining clamping device. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a clamping device for machining that can replace the traditional method of fixing parts by pneumatic clamps, further improving the stability of parts. It does not require a stable supply of compressed air, is more convenient to install and maintain, and has relatively low noise, which can effectively solve the problems in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for machining, comprising a fixed base and a clamping mechanism; Clamping mechanism: It includes a hexagonal sliding column, a rack plate, a vertical rod, and a clamping plate. The hexagonal sliding column is respectively set on the upper side inside the fixed base. A baffle is set at the end of the hexagonal sliding column near the center of the fixed base. The rack plate is slidably connected to the outside of the hexagonal sliding column. The vertical rod is slidably connected in the sliding groove set at the upper end of the fixed base. The lower end of the vertical rod is fixedly connected to the upper end of the vertically adjacent rack plate. The upper end of the vertical rod is set with a clamping plate. It can replace the traditional method of fixing parts by pneumatic clamps, further improving the stability of the parts. It does not require a stable supply of compressed air, and the installation and maintenance are more convenient while the noise is relatively low.
[0005] Furthermore, it also includes a control switch, which is located outside the fixed base. The input terminal of the control switch is electrically connected to an external power supply and can regulate the electrical components inside the equipment.
[0006] Furthermore, the clamping mechanism also includes a mounting rod and a drive gear. The mounting rod is rotatably connected to the left and right sides of the top wall of the fixed base, and drive gears are provided on the upper and lower sides of the outer arc surface of the mounting rod. The upper drive gear is meshed with the adjacent rack plate in the lateral direction, which can adjust the position of the clamping plate.
[0007] Furthermore, the clamping mechanism also includes rubber pads, which are all located in the middle of the inner arc surface of the clamping plate, thus preventing the clamping plate from damaging the parts.
[0008] Furthermore, a mounting cylinder is rotatably connected to the middle of the bottom wall of the fixed base. A gear is provided on the upper side of the outer arc surface of the mounting cylinder, and the lower drive gears are all meshed with the gear, which can drive the lower drive gear to rotate through the gear.
[0009] Furthermore, an output rod is rotatably connected to the lower side of the right wall of the fixed base. A worm is provided in the middle of the outer arc surface of the output rod, and a worm wheel is provided on the lower side of the outer arc surface of the mounting cylinder. The worm and the worm wheel are meshed and connected, and the mounting cylinder can be driven to rotate through the worm wheel.
[0010] Furthermore, a motor is provided on the lower side of the left wall of the fixed base. The right end of the motor output shaft is fixedly connected to the left end of the output rod. The input end of the motor is electrically connected to the output end of the control switch, and can drive the worm gear to rotate through the worm.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This clamping device for machining has the following advantages: By using the rack and pinion plate in conjunction with the drive gear, the position of the clamping plate can be adjusted, and the clamping plate is used to clamp and fix the parts, thus replacing the traditional method of fixing parts with pneumatic clamps. This further improves the stability of the parts, eliminates the need for a stable supply of compressed air, makes installation and maintenance more convenient, and reduces noise.

The lower ends of the uprights 33 are fixedly connected to the upper ends of the vertically adjacent rack plates 32. The upper ends of the uprights 33 are each provided with clamping plates 34. The clamping mechanism 3 also includes mounting rods 36 and drive gears 37. The mounting rods 36 are rotatably connected to the left and right sides of the top wall of the fixed base 1. On the side, drive gears 37 are provided on both the upper and lower sides of the outer arc surface of the mounting rod 36. The upper drive gear 37 is respectively engaged with the adjacent rack plate 32 in the lateral direction. The clamping mechanism 3 also includes rubber pads 35, which are all located in the middle of the inner arc surface of the clamping plate 34. Through the cooperation between the rack plate 32 and the drive gear 37, the position of the clamping plate 34 can be adjusted. Finally, the clamping plate 34 is used to clamp and fix the parts, thereby replacing the traditional method of fixing parts with pneumatic clamps. This further improves the stability of the parts, eliminates the need for a stable supply of compressed air, and makes installation and maintenance more convenient while also reducing noise.
[0016] It also includes a control switch 2, which is located outside the fixed base 1. The input terminal of the control switch 2 is electrically connected to an external power supply and can regulate the electrical components inside the equipment.

[0020] The working principle of the clamping device for machining provided by this utility model is as follows: During the use of the clamping device for machining, the parts to be machined are first placed in the middle of the upper end of the fixed base 1. Then, the motor 9 starts to run through the control switch 2. The output shaft of the motor 9 drives the worm 7 to rotate through the output rod 6. During the rotation of the worm 7, the worm 7 drives the worm wheel 8 to rotate through the meshing connection. The worm wheel 8 drives the gear 5 to rotate through the mounting cylinder 4. During the rotation of the gear 5, the gear 5 drives the lower drive gear 37 to rotate through the meshing connection.
