[0002] After searching, application number 202020071001.6 discloses a positioning device for processing a vehicle crossbeam, including a processing table, a support plate is fixedly connected to the left side of the processing table, a forward and reverse motor is fixedly connected to the upper surface of the support plate, and a cavity is opened on the front of the processing table, and a first bearing and a second bearing are fixedly embedded on the inner side walls of the cavity, respectively, and the output end of the forward and reverse motor extends to the interior of the first bearing and is fixedly connected to the inner ring of the first bearing.

[0003] In the comparative document, a positioning device for processing a trolley beam is used. During use, the support block is driven by a forward and reverse motor to move the trolley beam to clamp and initially fix it. The fixing bolt then drives the fixing pad to fix the top of the trolley beam, thereby achieving a double fixation of the trolley beam. However, during such use, the staff is required to manually operate the handle to rotate the fixing plate so that the fixing bolt is located above the trolley beam, and then use a wrench to rotate the fixing bolt to drive the fixing pad to move downward and contact the top of the trolley beam for fixation. The operation is relatively cumbersome, which reduces the efficiency of the equipment in processing the trolley beam. For this reason, we propose a fixing device for processing a trolley beam.

[0026] When the utility model is implemented, the control driving motor 14 drives the bidirectional threaded rod 13 to rotate, forcing the two nut sliders 12 threadedly connected to the outer wall of the bidirectional threaded rod 13 to move closer to each other, thereby driving the two clamping blocks 16 on the two supporting frames 15 to clamp and fix the trolley crossbeam, and at the same time, the position of the trolley crossbeam can be centered, thereby improving the practicality of the device.
