Description

Technical Field

[0001] The utility model relates to the technical field of solid shaft processing, and particularly relates to a clamping device for processing a hardware solid shaft. Background Technique

[0002] Solid shafts are commonly used as rotating shafts, that is, they bear both bending moment and torque during operation. They are the most common shafts in machinery, such as the shafts in various speed reducers, etc. The solid shaft will be processed to a certain extent on the shaft according to the actual use situation, for example: pin keyholes, pin key grooves, etc., and generally multiple positions on the shaft surface need to be processed during processing. Since the solid shaft is generally relatively long, it needs to be fixed during processing. After processing one position, the solid shaft needs to be rotated by a certain angle and then processed. Currently, when processing a solid shaft, generally the solid shaft is placed in a groove and then processed. After processing, the processing position of the solid shaft is adjusted by manual flipping. However, since the solid shaft is solid and relatively heavy, it is time-consuming and laborious during the flipping process, with low efficiency, and it is easy to have a position offset when placed in the groove, resulting in a significant decrease in processing accuracy.

[0003] After retrieval, Chinese Patent Publication (Announcement) No. CN212240132U discloses a clamping device for processing a solid shaft. Through the arrangement of the mounting sleeve and the through hole, this patent can perform multi-point support on the solid shaft of the long shaft type. One end of the solid shaft is fixed to prevent the position offset of the solid shaft during processing and increase the processing accuracy; and when the processing position of the solid shaft needs to be changed, the position of the solid shaft is changed by driving the mounting sleeve with a motor, and precise position adjustment can be performed through the shaft disk. However, when performing multi-point support on the solid shaft, it will block some areas of the solid shaft, which also causes inconvenience in processing. Moreover, the above patent is not convenient to clamp according to the length of the solid shaft as needed, and the size of the through hole on its fixed seat is fixed, which is not convenient to clamp solid shafts of different thicknesses. Therefore, it is very necessary to design a clamping device for processing a hardware solid shaft. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a clamping device for processing a hardware solid shaft, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0009] In order to enable the first screw rod to rotate, as a clamping device for processing a solid metal shaft of the present utility model, a first motor is installed on one side of the bottom base. The output end of the first motor penetrates through one side of the bottom base and is fixedly connected with the first screw rod.

[0010] In order to enable the second screw rod to rotate, as a clamping device for processing a solid metal shaft of the present utility model, a second motor is installed on the upper surface of the bottom base. The output end of the second motor is fixedly connected with a second screw rod.

[0024] In this embodiment, a first screw rod 10 is rotatably connected to the inner wall of the chute 5. The first screw rod 10 is threadedly connected to the fixing frame 8.

[0025] During specific use, when the first screw rod 10 rotates, it can perform a threaded movement with the fixing frame 8, thereby driving the fixing frame 8 to slide in the chute 5. When the second upper clamping seat 7 moves up and down, it can drive the sliding movement of the movable frame 9 and the fixing frame 8.

The threaded movement of the connecting frame 11 and the second screw rod 16 can drive the up and down movement of the connecting frame 11. At this time, the connecting frame 11 can drive the sliding rod 13 to move up and down through the sleeve rod 12 and drive another connecting frame 11 to move by the sliding rod 13. When the second upper clamping seat 7 moves up and down, it can drive the sliding movement of the movable frame 9 and the fixed frame 8. At this time, the first upper clamping seat 4 and the second upper clamping seat 7 can clamp the solid shaft, and the solid shaft can rotate through the roller so that the rotation of the solid shaft can process different positions of the solid shaft. By clamping both ends of the solid shaft, the processing obstruction during the processing of the solid shaft can also be reduced, facilitating the processing of the solid shaft and facilitating the clamping and processing of solid shafts with different thicknesses. When the first motor 14 operates, it can drive the rotation of the first screw rod 10 and make it perform a threaded movement with the fixed frame 8 to drive the movement of the fixed frame 8, and drive the position movement of the second upper clamping seat 7 through the second lower clamping seat 6 and the movable frame 9.
