A bidirectional screw 105 is rotatably arranged between the left and right ends of the fixing groove 102. Support bearings 113 are respectively provided on the left and right ends of the fixing groove 102. The two sides of the bidirectional screw 105 are respectively fixedly connected to the inner ring of the support bearing 113.

[0026] A drive motor 106 for rotating the bidirectional screw 105 is provided on the fixed groove 102. The output shaft of the drive motor 106 passes through the side wall of the fixed groove 102 and is fixedly connected to the bidirectional screw 105. Fixed blocks 107 that are screwed to the bidirectional screw 105 are slidably provided on both sides of the fixed groove 102. A telescopic push rod 108 is vertically provided on the top of the fixed block 107. An auxiliary fixing ring 109 is provided on the output shaft of the telescopic push rod 108. An auxiliary pressure module is provided on the auxiliary fixing ring 109.

[0027] The worker can first insert the workpiece into the main fixing ring 104 and the auxiliary fixing rings 109 on both sides, so that the middle part of the workpiece corresponds to the main fixing ring 104. Then the main pressing module can press the middle part of the workpiece onto the main fixing ring 104.

[0028] Next, the output axis of the telescopic push rod 108 can be shortened downwards by a certain length, causing the bottom of the auxiliary fixing ring 109 to disengage from the auxiliary support of the workpiece. Then, the drive motor 106 is started, driving the bidirectional screw 105 to rotate, driving the fixing blocks 107 on both sides to slide relative to the fixing groove 102 and move away from each other until the positions of the fixing blocks 107 and the auxiliary fixing ring 109 correspond to the positions of the two sides of the workpiece. Then, the output axis of the telescopic push rod 108 can be extended upwards by a certain length, causing the bottom of the auxiliary fixing ring 109 to provide auxiliary support for the workpiece again. Then, the workpiece can be fixed to the auxiliary fixing ring 109 by the auxiliary clamping module. In this way, while flexibly fixing workpieces of various sizes, wear at the connection between the auxiliary fixing ring 109 and the workpiece can be avoided. After that, the workpiece can be welded.

[0033] After the horizontal position of the auxiliary fixing ring 109 is adjusted and the bottom of the auxiliary fixing ring 109 supports and fixes the workpiece on both sides again, the auxiliary pressing screw rod 301 can be driven to vertically screw downward relative to the auxiliary fixing ring 109, and under the cooperation of the vertical sliding operation of the auxiliary guide insertion rods 304 relative to the auxiliary guide insertion holes 303 and the auxiliary fixing ring 109, the auxiliary pressing plate 302 is driven to move downward until it presses against the top of the workpiece on both sides, and the auxiliary pressing plate 302 is prevented from being abraded on the workpiece by rotating and pressing on the workpiece.

[0034] Subsequently, only the upward screwing adjustment of the auxiliary pressing screw rod 301 is needed, so that the auxiliary fixing plate can be driven to reset upward and release the pressing and fixing of the workpiece on both sides.

[0035] According to another embodiment of the present application, as shown in FIGS. 5, the upper end of the main pressing screw rod 201 is also provided with a first handle 205. Figure 1 , 2 With the help of the second handle 305, the worker can conveniently manually adjust the screwing of the main pressing screw rod 201, so that the pressing and fixing of the workpiece in the middle part by the main pressing plate 202 can be more conveniently realized or released.
