Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of fixtures, in particular to a finishing fixture for a gear intermediate shaft. Background Art
[0002] The gear intermediate shaft, usually referred to as the intermediate shaft, is a shaft that connects two independent gear systems and acts as a bridge for transmitting power. In gear transmission, the intermediate shaft connects different gears to achieve smooth power transmission and speed and torque conversion. The intermediate shaft is usually made into an integral structure with the gears to improve the stability and efficiency of the transmission.
[0003] Because the positions and numbers of the shafts and gears on different intermediate shafts are usually different, it is not easy to clamp and fix the intermediate shaft when finishing the gears on the intermediate shaft. If only the two ends of the intermediate shaft are clamped and fixed, the clamping stability is poor, which can easily affect the finishing quality. If a special processing fixture is set up for each different intermediate shaft, the investment cost will increase. Therefore, a processing fixture is needed that can cope with the different positions and numbers of the shafts and gears of different intermediate shafts to ensure the stability of clamping during finishing of the intermediate shaft. Utility Model Content

[0006] The base is provided with a plurality of mounting holes for fixing;
[0007] A clamping group is slidably connected to the base and is provided in plurality;
[0008] The support member is installed on the base and is used to support the clamping group before clamping.

[0033] The beneficial effects of the utility model are:
[0034] 1. By setting up multiple clamping groups and slidingly connecting the clamping groups to the base, different gear intermediate shafts can be stably clamped when clamping is difficult due to the different positions and numbers of the shafts and gears, thereby maintaining the accuracy of fine processing and ensuring product quality.

[0045] A clamping group is slidably connected to the base 1 and is provided in plurality;
[0046] The support member 3 is installed on the base 1 and is used to support the clamping group before clamping.
[0047] It can be seen from this embodiment that by setting up multiple clamping groups and slidingly connecting the clamping groups to the base 1, different gear intermediate shafts can be stably clamped when clamping is difficult due to the different positions and numbers of the shafts and gears, thereby maintaining the accuracy of fine processing and ensuring product quality. In addition, the setting of the support member 3 facilitates the pre-support of the gear intermediate shaft, facilitates subsequent clamping, and improves convenience.

[0053] The threaded rod 44 is horizontally arranged through the mounting seat 41 and is connected to the clamping block 42 with a bearing, and a knob 45 is provided at the end away from the clamping block 42;
[0054] A first threaded sleeve 46 is mounted on the mounting seat 41 and engages with the threaded rod 44 , and an abutment portion 460 is provided at one end of the first threaded sleeve 46 close to the clamping block 42 ;
[0055] The abutment portion 460 is formed by extending one end of the second threaded sleeve 46 radially away from the axis.
[0056] Meanwhile, the sliding connection between the bottom plate 40 and the base 1 may be achieved by using a slider and a slide rail. Specifically, the slide rail is installed on the base 1 , and the slider is connected to the bottom plate 40 .
[0057] As can be seen in this embodiment, multiple clamping groups each use two clamping members 4 arranged opposite to each other. By adjusting the two clamping members 4 in the clamping group to the same and appropriate position, the threaded rod 44 is rotated to drive the clamping blocks 42 of the two clamping members 4 to clamp the middle of the gear, thereby improving the convenience of clamping and ensuring stability and precision of finishing.
