[0029] The specific implementation of the encoder debugging fixture of the utility model is described in detail below in conjunction with the accompanying drawings.

[0030] See attached Figure 1-3The encoder debugging fixture is used to debug and detect the encoder. A platform seat 1 is arranged on the top, a skirt 3 is arranged below the upper platform 2 of the platform seat 1, and a channel 4 is arranged in the middle position of the upper platform 2. The channel 4 is used to cooperate with the installation of the working shaft 5.

A top sheet 7 is arranged above the lifting block 6, and a lifting port 8 is arranged on the upper platform 2. The lifting port 8 is located at the opening of the upper platform 2 near the channel 4. When the lifting block 6 rises, the top sheet 7 extends from the lifting port 8. There are three lifting sheets and three lifting ports 8, which are arranged in an arc shape on a concentric circle. The position of the top sheet 7 matches the position of the head of the working shaft 5.

[0032] The driving sleeve block 9 is sleeved on the outside of the lifting block 6. The driving sleeve block 9 includes a spiral groove 10 arranged on the outside. A clamping column 11 is fixedly arranged on the lifting block 6. The clamping column 11 is matched in the spiral groove 10. There are three spiral grooves 10 and three clamping columns 11. The three spiral grooves 10 are evenly distributed on the outside of the driving sleeve block 9. The three clamping columns 11 are fixed on the lifting block 6 and respectively matched with the three spiral grooves 10. A small bearing is arranged on the clamping column 11, which is matched in the spiral groove 10 through the small bearing.

[0033] A rotating handle 12 is provided at the lower end of the driving sleeve block 9. The rotating handle 12 can be provided at a plurality of positions of the driving sleeve block 9, and the position can be changed so as to change the torsion point of the acting force.

[0034] A bearing seat 13 is arranged below the hole 4, and the bearing seat 13 is threadedly connected to the lower end of the hole 4. A working shaft 5 is installed in the hole 4, the upper end of the working shaft 5 is located on the upper platform 2, and the lower end is installed in the bearing seat 13 through a bearing.
