DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0019] See also Figures 1 to 5 A rotating platform includes a base 100, a support platform 110 is arranged on the base 100, a rotatable workbench 120 is arranged on the support platform 110, and two workstations are arranged on the workbench 120. A motor for driving the workbench 120 to rotate is arranged in the base 100, a first limiter is arranged on the side of the workbench 120 facing the base 100, a telescopic rod 200 that can be extended and retracted is arranged on the base 100, a second limiter is arranged on one end of the telescopic rod 200 facing the workbench 120, a pedal 210 is arranged on the other end of the telescopic rod 200, a control switch 140 for controlling the start and stop of the motor is arranged at the bottom of the pedal 210, the telescopic rod 200 moves downward to squeeze the control switch 140 so that the motor drives the workbench 120 to rotate, and when the telescopic rod 200 is reset, the first limiter and the second limiter contact each other to limit the rotation of the workbench 120. Two first limiters are arranged, and the two first limiters are respectively placed on two symmetrical sides. The pedal 210 is stepped on to move the telescopic rod 200 downward and the control switch 140 is pressed. Each time the control switch 140 is pressed, the motor drives the workbench 120 to rotate 180°, so that the two workstations of the workbench 120 are exchanged, and the workstation at the welding joint can perform welding, while the other workstation can take and place parts. At the same time, when the telescopic rod 200 moves downward, the first limiter and the second limiter are mutually offset, so that the workbench 120 can rotate smoothly. When the pedal 210 is released, the telescopic rod 200 moves upward, and the first limit piece is in a position where it can be locked with the second limit piece. At this time, the second limit piece has passed the position of the first limit piece and can continue to rotate. When the other side rotates to the position of the first limit piece, the second limit piece on the other side is locked with the first limit piece, thereby limiting the movement of the workbench 120. As a result, the workbench 120 automatically rotates 180° every time the pedal 210 is stepped on. The locking of the first limit piece and the second limit piece can ensure the accuracy of the workstation positioning on the workbench 120.

[0020] Specifically, the first position-limiting member includes a support plate 121 extending from the workbench 120 toward the base 100, a moving block 310 is provided on the support plate 121, a first mounting groove 311 is provided on the moving block 310, a first magnet 300 is embedded in the first mounting groove 311, a guide groove 122 is provided on the support plate 121, and a guide block 312 embedded in the guide groove 122 is provided on the moving block 310. The moving block 310 enables the first magnet 300 to move in a vertical direction relative to the support plate 121. The second position-limiting member includes a second magnet 400 that can attract the first magnet 300, a telescopic groove 220 is provided at one end of the telescopic rod 200 facing the workbench 120, a mounting plate 410 that can move along the telescopic groove 220 is provided in the telescopic groove 220, a second mounting groove 411 is provided on the mounting plate 410, the second magnet 400 is embedded in the second mounting groove 411, and a first spring 221 that abuts against the mounting plate 410 is provided in the telescopic groove 220. When the workbench 120 rotates to lock the first stopper with the second stopper, the first magnet 300 and the second magnet 400 contact and attract each other, and the first spring 221 can buffer the impact of the first magnet 300 and the second magnet 400 when they contact. Since the workbench 120 needs to be lowered as a whole during welding, the moving block 310 that can move in the vertical direction can keep the first magnet 300 and the second magnet 400 in an adsorption state when the workbench 120 is lowered as a whole.

[0021] The base 100 is provided with a support tube 130, and the part of the telescopic rod 200 placed in the support tube 130 is provided with a baffle 201. The support tube 130 is provided with a second spring 131 which is sleeved on the telescopic rod 200 and abuts against the baffle 201. Under normal conditions, the baffle 201 abuts against the top of the telescopic tube under the push of the second spring 131, and at this time, the first limiter is in a position where it can be mutually locked with the second limiter. When the pedal 210 is stepped on, the telescopic rod 200 moves downward, and the second spring 131 is compressed, and at this time, the first limiter and the second limiter are mutually misaligned.

[0022] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
