[0016] The following is a detailed description of the embodiments of the present utility model in conjunction with the accompanying drawings.

[0017] See also Figures 1 to 4The utility model provides a forklift gearbox clamp, which includes a base plate 1, a processing hole 6 is opened in the middle of the upper end of the base plate 1, the base plate can be turned over by the machining center, and the tool of the machining center can pass through the machining hole to process the lower end surface of the gearbox, and a support pad 2 and an angle positioning block 4 for positioning the corners of the gearbox are arranged on the rear side of the upper end of the base plate 1, and an upper clamping assembly 8 and a positioning pad 3 for supporting and positioning the front of the gearbox are arranged on the front side of the upper end of the base plate 1. The positioning pad 3 is composed of a lower support column coaxially connected to an upper positioning shaft, and a chamfer is arranged on the top of the positioning shaft. The support column can support the gearbox like the two support pads on the rear side, and the positioning shaft positions the front of the gearbox. The upper end of the base plate 1 is provided with side positioning blocks 5 and a lower clamping assembly 7 located on the left and right sides of the machining hole 6, and the upper clamping assembly 8 and the lower clamping assembly 7 can respectively clamp the upper and lower plates of the gearbox. Install the base plate on the workbench of the machining center, place the gear box on the support pad and the positioning pad, move the gear box to the left so that it is against the side positioning block, the corner positioning block and the positioning pad, so as to position the gear box, and then use the upper clamping assembly and the lower clamping assembly to clamp the upper and lower plates of the gear box respectively, the base plate can be turned over, and the tool of the machining center can pass through the machining hole to process the lower end face of the gear box, so that the machining center can process the upper and lower end faces of the gear box.
