[0026] See also Figure 1-4The utility model provides a new type of frame production welding positioning tooling technical solution: it includes a base plate 1 and brackets 101 fixedly installed on both sides of the outer top surface of the base plate 1, a cross connecting plate 102 is fixedly connected between the two brackets 101, the outer top surface of the cross connecting plate 102 is provided with screw holes 103 arranged at equal intervals, the outer top surface of the cross connecting plate 102 is symmetrically provided with positioning seats 104 at the front and rear ends, and the outer top surface of the cross connecting plate 102 is symmetrically provided with positioning plates 105 at the left and right ends. The two positioning plates 105 correspond to each other. A positioning seat 2 106 is symmetrically installed on the bottom of the inner side wall, and a square plate 107 is fixedly connected to the inner top surface of the two brackets 101. A positioning component 2 for limiting the welded frame body is provided between the two square plates 107. The positioning component 2 includes a bidirectional screw rod 201 rotatably installed between the two square plates 107. The outer circumferential surface of the bidirectional screw rod 201 is threadedly sleeved with a slider 1 202 at both ends. The front and rear sides of the two sliders 1 202 are fixedly connected with a straight plate 203. The four straight plates 203 The outer top surface of each of the four straight plates 203 is provided with a block 204, and the outer top surface of the block 204 is provided with a limit piece 3. The two ends of the bidirectional screw rod 201 extend to the left and right outer walls of the two square plates 107 respectively, and a rotating handle 205 is fixedly installed on the outer circumferential surface of the left end of the bidirectional screw rod 201. A groove 4 is provided on the outer top surface of each of the four straight plates 203. Threaded rods 401 are rotatably installed on the inner side walls of both sides of the four grooves 4. Slide blocks 402 are threadedly sleeved on the outer circumferential surface of the four threaded rods 401, and the four slide blocks 402 are screwed together. Block 2 402 is fixedly connected to the four blocks 204. At the same time, the opposite ends of the threaded rod 401 extend to the front and rear outer walls of the straight plate 203 and are fixedly connected to the knob 403. The straight blocks 5 are fixedly installed on the outer side walls corresponding to the two groups of positioning seats 104. The outer top surfaces of the two straight blocks 5 are fixedly connected to the cross connecting plate 102 by bolt 1. The abutment seats 501 are fixedly installed on the opposite outer side walls of the two positioning plates 105. The inner bottom surfaces of the two abutment seats 501 are fixedly connected to the cross connecting plate 102 by bolt 2. The first and second bolts are tightened in sequence according to the size of the frame body to fix the positioning seat 104 and the positioning seat 2 106 on the positioning plate 105 on the cross connecting plate 102, and then the straight crossbeam and the U-shaped frame of the frame body are placed on the positioning seat 104 and the positioning seat 2 106 in sequence. Thereafter, the rotating handle 205 is turned to drive the bidirectional screw rod 201 to rotate and thereby the slider 1 202 drives the straight plate 203 to move away from or close to each other. Then, the knob 403 is turned to drive the threaded rod 401 to rotate and drive the block 204 to move toward the direction of the machine body in turn, thereby allowing the limit member 3 to press and abut the frame body, which can realize fast and accurate positioning of the frame body, effectively improving the welding efficiency and positioning accuracy, avoiding welding deformation, and ensuring the processing quality of the product.

[0027] The limiting member 3 comprises a cylinder 301 rotatably mounted on the outer top surfaces of the four blocks 204. A small circular plate 303 is fixedly connected to the inner bottom surface of the cylinder 301 via a return spring 302. A sliding rod 304 is fixedly connected to the center of the outer top surface of the small circular plate 303. One end of the sliding rod 304 extends to the outer top surface of the cylinder 301 and is fixedly connected to a pressing plate 305. Pulling the pressing plate 305 causes the sliding rod 304 to move upward along the inner side of the cylinder 301. When the pressing plate 305 is above the frame body, it is released. Under the elastic expansion and contraction action of the return spring 302, the pressing plate 305 abuts against the frame body, preventing the frame body from shaking during welding, which would affect the welding quality.

[0028] The working principle of the present invention is as follows: first, according to the size of the frame body, the two positioning seats 104 and the positioning plate 105 are placed on the cross connecting plate 102 in sequence, and the bolts 1 and 2 are tightened to fix them to each other, and then the straight beams and U-shaped frames of the frame body are placed on the positioning seat 104 and the positioning seat 2 106 in sequence.

[0029] At the same time, the rotating handle 205 is rotated to drive the bidirectional screw rod 201 to rotate, so that the slider 1 202 drives the straight plate 203 to move away from or closer to each other.

[0030] At the same time, the knob 403 is turned to drive the threaded rod 401 to move with the block 204 toward the main body of the machine. When it is close to the main body of the frame, the compacting plate 305 is pulled to make the sliding rod 304 move upward along the inner side of the cylinder 301. Then, the cylinder 301 is rotated to make the compacting plate 305 above the main body of the frame, and the compacting plate 305 is released to abut against the main body of the frame under the elastic expansion and contraction action of the return spring 302, thereby realizing fast and accurate positioning of the main body of the frame, effectively improving the welding efficiency and positioning accuracy, avoiding welding deformation, and ensuring the processing quality of the product.

[0031] Finally, welding can be performed on the connection between the two U-shaped frames and the straight beams of the frame body.

[0032] The above is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this application shall be implemented in accordance with conventional means in the art unless otherwise specified or limited.
