Support legs are installed at the four corners of the bottom of the operation platform by screws, and the ends of the support legs are designed as enlarged foundations. A column is installed at the rear of the operation platform by screws, and the column is designed in an L shape and extends towards the front end of the operation platform. A hydraulic cylinder is installed below the horizontal plate of the column by screws, and the piston rod of the hydraulic cylinder is connected to the pressing plate, and the bottom of the pressing plate contacts the transmission. A turntable is installed at the vertical plate of the column by a bearing, and the output end of the transmission is connected to the turntable. A chute is opened on one side of the operation platform, a lead screw is installed in the chute, the slider is installed in the chute, and the lead screw is threadedly connected to the slider. The lead screw is connected to the motor, and the motor is located at one end of the operation platform.

[0006] Preferably, the top of the slider is higher than the top of the operation platform. A notch is opened on the higher part of the slider, a clamping plate is installed in the notch, the clamping plate is distributed at a right angle to the slider, and a plurality of mounting grooves are opened on the clamping plate, and a limiter is installed in the mounting groove, and the limiter contacts the transmission.

[0007] Preferably, the limiter includes a fixing plate, a buffer spring, a cylinder, and a front baffle. The fixing plate is connected to the mounting groove, and a plurality of buffer springs are installed on the fixing plate by screws. The end of the buffer spring is connected to the cylinder, and the cylinder passes through the front baffle and extends along. The front baffle is connected to the fixing plate through a connecting rod.

[0008] Preferably, the cylinder can contact the gearbox, and multiple limiters can be installed on the clamping plate.

[0009] Compared with the prior art, the utility model has the following advantages: The utility model is reasonably designed; the turntable is connected to the output end of the gearbox so that the gearbox can rotate as required, and the temperature is measured during and after the rotation process; the pressing plate, the turntable, and the stopper can fix three points of the gearbox, thereby improving the stability of the gearbox; the stopper can change its displacement under the action of the slider and the clamping plate to adapt to gearboxes of different sizes; when the shape of the gearbox is irregular, the cylinder at the stopper contacts the gearbox, and the cylinders at different positions contact the gearbox. Due to the irregular shape of the gearbox, the protruding part of the gearbox will compress the buffer spring by a large displacement, and the buffer spring at the concave position is compressed less. The buffer spring and the cylinder can be used to fix the special-shaped gearbox. BRIEF DESCRIPTION OF THE DRAWINGS
