[0002] The transmission mechanism needs to be welded during production and manufacturing, and a positioning device is needed to position the transmission mechanism components during welding, so as to facilitate welding. However, the existing transmission mechanism welding positioning device has the following problems: it can often only position one group of transmission mechanism components at the same time, which results in that after welding is completed, it is necessary to wait for the transmission mechanism components to cool down before the transmission mechanism components can be removed from the positioning device, and then the next group of transmission mechanism components can be placed on the positioning device before welding can continue, which results in low welding efficiency, and the existing transmission mechanism welding positioning device has poor functionality. For example, the existing transmission mechanism welding positioning device cannot be automatically stored when not in use, and is often large in size, which requires a large space for storage when not in use, and also causes trouble for its transportation. In addition, the existing transmission mechanism welding positioning device is difficult to treat the exhaust gas generated by welding, and the direct emission of exhaust gas will pollute the surrounding environment.

[0049] Since there are four V-shaped positioning clamps 9 and four positioning cylinders 7, four groups of transmission mechanism components can be positioned during welding, thereby greatly improving the welding effect.

[0050] In this embodiment, refer to Figure 3 The driving mechanism 2 includes a motor 201, which is fixedly mounted on the front end surface of the support vertical plate 1. The rear end of the output shaft of the motor 201 passes through the front end of the support vertical plate 1 and extends to the inside of the support vertical plate 1. The motor 201 is mechanically linked with a first mounting shaft 204 and a second mounting shaft 205, and the first mounting shaft 204 and the second mounting shaft 205 are symmetrically arranged on the left and right sides of the output shaft of the motor 201.

[0051] The first mounting shaft 204 and the second mounting shaft 205 respectively pass through the two first receiving grooves 11, and the first mounting shaft 204 and the second mounting shaft 205 are both rotatably connected to the inner wall of the supporting vertical plate 1, and the two processing tables 4 are fixedly mounted on the first mounting shaft 204 and the second mounting shaft 205 near one end thereof.

[0052] A main gear 202 is fixedly mounted on the rear end of the output shaft of the motor 201 . A slave gear 203 is meshed on the right end of the main gear 202 . The slave gear 203 is fixedly mounted on the front end of the first mounting shaft 204 .

[0053] A first transmission wheel is fixedly mounted on the front end of the output shaft of the motor 201 , and a second transmission wheel is fixedly mounted on the front end of the second mounting shaft 205 . The first transmission wheel is connected to the second transmission wheel via a transmission belt 206 .

[0054] After use, first flip the supporting side leg 5 to store the supporting side leg 5 in the second storage groove 13, and then rotate the limiting baffle 12 to limit the supporting side leg 5 stored in the second storage groove 13;

[0055] Then start the motor 201. The motor 201 can drive the first installation shaft 204 to rotate through the main gear 202 and the slave gear 203. The motor 201 can also drive the second installation shaft 205 to rotate through the first transmission wheel, the second transmission wheel and the transmission belt 206. The rotating first installation shaft 204 and the second installation shaft 205 can drive the two processing tables 4 to rotate into the two first storage grooves 11, thereby storing the processing tables 4, thereby reducing the storage volume of the present invention and facilitating the transportation of the present invention.

[0056] Reference Figure 1-2 as well as Figure 4 A top plate mechanism 10 is fixedly installed on the upper end of the support vertical plate 1, and the top plate mechanism 10 and the support vertical plate 1 are detachably connected, so that when the mechanism is not in use, the top plate mechanism 10 can be removed from above the support vertical plate 1 to facilitate transportation and storage.

[0057] The top plate mechanism 10 includes a top plate shell 1001, a vertically arranged partition 1006 is fixedly installed inside the top plate shell 1001 and located directly above the support vertically, two exhaust fans 1002 are symmetrically fixedly installed inside the top plate shell 1001, the air inlet end of the exhaust fan 1002 passes through the lower end of the top plate shell 1001, and extends to the bottom of the top plate shell 1001, and is fixedly connected with an air inlet cover 1005, and the two air inlet covers 1005 are symmetrically arranged on the left and right sides of the support vertically;

[0058] An air outlet is provided at one end of the exhaust fan 1002 away from the partition 1006, and an activated carbon filter 1003 is provided at the end of the air outlet away from the partition 1006. The activated carbon filter 1003 and the air outlet are both located inside the top plate shell 1001, and multiple air outlet pipes 1004 are fixedly connected at both ends of the top plate shell 1001.

After adsorption and purification by the activated carbon filter 1003, it is discharged through the air outlet pipe 1004. The above design can improve the environmental protection effect.

[0060] Reference Figure 1-2 as well as Figure 4 A base mechanism 3 is fixedly mounted on the lower end surface of the supporting vertical plate 1.

[0061] The base mechanism 3 includes a base 301, and four universal wheels 304 are fixedly installed in a rectangular array at the lower end of the base 301;

[0062] Four supporting cylinders 302 are fixedly installed in a rectangular array inside the base 301 . The lower ends of the output ends of the supporting cylinders 302 pass through the base 301 , and the lower ends of the output ends of the four supporting cylinders 302 are fixedly installed in a rectangular array on the upper end surface of the positioning plate 303 .

[0063] The positioning plate 303 is located between the four universal wheels 304 , and the lower end of the positioning plate 303 is provided with anti-slip grooves.

[0064] The universal wheel 304 can be used to facilitate the movement of the present invention. After moving to the destination, the supporting cylinder 302 can be started. The support cylinder 302 can drive the positioning plate 303 to move downward. The downward positioning plate 303 can provide stable support for the present invention. At this time, the universal wheel 304 is separated from the ground, thereby enabling the present invention to be stably placed.

[0065] like Figure 6-10 As shown, in another embodiment provided by the present invention, a limiting mechanism 401 is provided between the supporting side leg 5 and the processing table 4, and the limiting mechanism 401 includes a limiting rod 402, a push rod 403 and a blocking rod 404;

[0066] A connecting tube 405 is provided in the second receiving groove. The connecting tube 405 is a hollow structure with openings at both ends. The limiting rod 402 passes through the connecting tube 405 and the limiting rod 402 can slide along the axial direction of the connecting tube 405. The design of the connecting tube 405 limits the displacement of the limiting rod 402, so that it can only move in a straight line direction; a push rod 403 is provided at the end of the supporting side leg 5, and a blocking rod 404 is provided at the bottom of the limiting rod 402, and the blocking rod 404 is close to the push rod 403; a limiting hole 406 is provided on the first receiving groove, and the limiting hole 406 faces the limiting rod 402. The end of the limiting rod 402 is connected to the end of the second receiving groove by a return spring 407, and the return spring 407 has a pulling force on the limiting rod 402 to make the limiting rod 402 away from the limiting hole 406;

[0067] A spring sheet 408 is also provided at the end of the second receiving groove, and the spring sheet 408 has a first end 409 located in the second receiving groove and a second end 410 extending to the outside, and the first end 409 is located above the push rod 403; the spring sheet 408 is a rigid sheet structure, which is installed on the processing table 4 through a torsion spring or a similar installation structure, so that it can be flipped and adjusted, and the whole body has elasticity, so that the first end 409 can be pushed upward by the push rod 403. When the upward thrust of the push rod 403 is lost, the first end 409 can be restored to a horizontal position under the elastic force, and the end of the first end 409 is limited to the side of the push rod 403, which plays a limiting role on the push rod 403, so that the supporting side leg 5 cannot continue to flip.

[0068] When the supporting side leg 5 is flipped out of the second receiving slot, the push rod 403 can push the first end 409 and push the blocking rod 404. When the supporting side leg 5 is flipped to a vertical state, the first end 409 can be attached to the side of the push rod 403, and the end of the limiting rod 402 can be inserted into the limiting hole 406.

[0069] Pressing the second end 410 can cause the first end 409 to flip upward and separate the first end 409 from the push rod 403, so that the supporting side leg 5 can flip into the second receiving groove. Then the push rod 403 is separated from the blocking rod 404, so that the limiting rod 402 is disengaged from the limiting hole 406 under the pulling force of the return spring 407, thereby releasing the limitation of the processing table 4 and allowing the processing table 4 to be stored in the first receiving groove.

[0070] Through the design of the limiting mechanism 401, when the supporting side leg 5 is flipped to the vertical state, the position of the supporting side leg 5 and the processing table 4 can be limited by the limiting mechanism 401, so that they are limited to a stable state, which is more stable during processing. In addition, due to the limitation of the limiting mechanism 401, when the supporting side leg 5 is in a vertical state, the processing table 4 cannot be flipped upward into the first receiving groove, and the supporting side leg 5 is also limited so that it cannot be flipped upward into the second receiving groove, thereby ensuring the stability of the components. When the limiting effect of the limiting mechanism 401 is cancelled, the components can be quickly retracted to their original positions.
