The pressure block 43 is used to abut the upper end surface of the gearbox 10 housing.

[0037] Reference Figure 2 、 Figure 3The tooling base 2 is provided with a drive assembly 5 that rotates the output shaft of the gearbox 10. The drive assembly 5 includes a driven gear 51 housed within the drive cavity 24 and coaxially fixedly sleeved on the output shaft of the gearbox 10, a rotary motor 52 disposed on the tooling base 2, and a driving gear 53 housed within the drive cavity 24 and coaxially fixedly sleeved on the output shaft of the rotary motor 52.

[0039] The implementation principle of an automatic lubrication device for a gearbox 10 in an embodiment of the present application is as follows: after the driven gear 51 is installed on the output shaft of the gearbox 10, the output shaft of the gearbox 10 is inserted into the placement hole 25, so that the positioning column 26 is inserted into the positioning hole 102, effectively limiting the horizontal sliding freedom of the gearbox 10, and then rotating the pressure block 43 so that the lower end surface of one end of the pressure block 43 abuts against the upper end surface of the gearbox 10 housing, and locking the fixing bolt 42 so that the lower end surface of the nut of the fixing bolt 42 abuts against the upper end surface of the pressure block 43, so that the pressure block 43 presses the gearbox 10 housing.
