[0040] As shown in Figures 1 to 6 In an embodiment, a door frame welding workbench 1 includes a table frame 10, a material placing disc 20 and a supporting assembly 30. The material placing disc 20 is rotatably arranged on the table frame 10. The supporting assembly 30 includes a tooth block 31, a sliding tooth seat 32 and a clamping block 33, a clamping driving element 34 and a releasing driving element 35. The clamping driving element 34 is arranged on the material placing disc 20. The sliding tooth seat 32 is slidably arranged on the material placing disc 20, and the sliding tooth seat 32 is connected with the clamping driving element 34, so that the clamping driving element 34 drives the sliding tooth seat 32 and the material placing disc 20 to clamp the door frame together. The tooth block 31 is arranged on the material placing disc 20. The clamping block 33 is slidably arranged on the sliding tooth seat 32, and the clamping block 33 is connected with the tooth block 31. The releasing driving element 35 is arranged on the material placing disc 20, and the releasing driving element 35 is used to push the clamping block 33 away from the tooth block 31, so that the sliding tooth seat 32 releases the door frame.

[0041] It should be noted that the table frame 10 is provided with a circular groove, and the material placing disc 20 is provided with a circular table, which is embedded in the circular groove, so that the material placing disc 20 can rotate relative to the table frame 10. Further, a through hole is formed in the inner bottom wall of the circular groove, and a through hole is formed in the circular table, and the diameter of the through hole is consistent with the diameter of the through hole and is aligned with each other. One end of the release driving piece 35 is slidingly arranged in the circular table, and the other end of the release driving piece 35 is slidingly arranged in the table frame 10 through the through hole and the through hole. Further, the material placing disc 20 is a square structure, for example, the material placing disc 20 is a rectangular structure, and the four edges of the material placing disc 20 are provided with the protruding stoppers 21. Further, the material placing disc 20 is provided with a tooth groove 22, and the tooth block 31 is located in the tooth groove 22, and the thickness of the tooth block 31 is consistent with the depth of the tooth groove 22, so that after the tooth block 31 is located in the tooth groove 22, the tooth block 31 and the material placing disc 20 are in the same horizontal plane. Further, the material placing disc 20 is provided with a plurality of sliding rails, and each sliding rail is located on the two sides of the tooth groove 22, and the sliding tooth seat 32 is provided with a guide block matched with the sliding rail, so that the sliding tooth seat 32 can slide back and forth above the tooth block 31. Further, the clamping block 33 is slidingly arranged on the sliding tooth seat 32, and the sliding direction of the clamping block 33 is perpendicular to the sliding direction of the sliding tooth seat 32, for example, the sliding tooth seat 32 slides horizontally relative to the material placing disc 20, and the clamping block 33 slides vertically relative to the sliding tooth seat 32, so that when the sliding tooth seat 32 slides above the tooth block 31, the clamping block 33 can slide downward to be clamped into the tooth block 31. Further, the tooth block 31 is provided with a plurality of inclined teeth, and each inclined tooth is equidistantly distributed, and each inclined tooth faces the edge direction of the material placing disc 20, and the clamping block 33 is also provided with an inclined surface portion 331 matched with any one inclined tooth, so that the inclined surface portion 331 is matched with the inclined tooth. Since each inclined tooth faces the edge of the material placing disc 20, when the sliding tooth seat 32 drives the clamping block 33 to slide from the material placing disc 20 to the edge of the material placing disc 20, the clamping block 33 can slide from one end of the tooth block 31 to the other end of the tooth block 31, and since the inclined tooth is inclined, the clamping block 33 cannot slide back to the previous inclined tooth after sliding through one inclined tooth, so that the sliding tooth seat 32 can adjustably keep the push-to-open door frame close to the stopper 21 on the edge of the material placing disc 20, so that the sliding tooth seat 32 and the stopper 21 jointly clamp the door frame. Further, the end of the clamping block 33 away from the inclined surface portion 331 is provided with a guide rod, the end of the guide rod away from the inclined surface portion 331 is arranged in the sliding tooth seat 32, and a return spring is sleeved on the guide rod, and the return spring pushes the sliding tooth seat 32 and the clamping block 33 respectively, so that the inclined surface portion 331 is continuously matched with the inclined tooth.

[0053] As shown in Figures 1 to 5 , in an embodiment, the four corners of the material placing disc 20 are of an open structure, so that when the door frame is placed on the material placing disc 20, the four corners of the frame composed of the door frame are exposed outside, so as to facilitate the welding of the corner positions by the production personnel.

[0054] As shown in Figures 2 to 5 , Figure 11 , in an embodiment, the release driving member 35 further includes a ring block 354, the ring block is a circular ring structure, the ring groove is formed on the end of the sleeve 352 away from the top frame 351, the ring block 354 is sleeved in the ring groove, the ring block 354 is rotationally connected with the foot rod 353, so that the ring block 354 can rotate relative to the sleeve 352, and the foot rod 353 can drive the ring block 354 to push the sleeve 352 to move upward, so that the sleeve 352 can rotate and push the top frame 351 at the same time. In this way, the production personnel can rotate the material placing disc 20 and also loosen the door frame.

[0055] As shown in Figures 2 to 5 , Figure 12As shown, in one embodiment, the clamping drive member 34 further includes a circular cover 344. A cover groove is defined on the end of the rod 3431 away from the conversion block 3432, and the cover 344 is sleeved within the cover groove. Furthermore, the diameter of the cover 344 is consistent with the diameter of the rod 3431, enabling the rod 3431 to drive the cover 344 into sliding engagement with the sleeve 352. The end of the cover 344 away from the rod 3431 is rotatably connected to the pedal 342, enabling the cover 344 to rotate relative to the rod 3431 and the pedal 342 to drive the cover 344 to push the rod 3431 upward. The upward movement of the rod 3431 causes the push seat 341 to push the sliding gear seat 32 into adjustable engagement with the tooth block 31, thereby enabling the push block 322 and the stop bar 21 to jointly clamp the door frame while adjusting the tension. In this way, the production staff can rotate the material tray 20 and clamp the door frame at the same time.

[0056] like Figures 1 to 6 As shown, in one embodiment, an arc surface is provided on the side surface opposite to the stop bar and the top block 322. The two arc surfaces can quickly guide the door frame onto the loading tray 20, so that the stop bar and the top block 322 can quickly clamp the door frame together to improve the loading and unloading time during the door frame welding process.

[0057] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
