[0032] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0033] like Figure 1-5 As shown, a stud 9 welding positioning fixture with anti-splash function includes a frame 1; it also includes: a clamping mechanism 3, the number of which is two, and the two clamping mechanisms 3 are respectively arranged on the front side and the left side of the frame 1; a shielding positioning mechanism 7, the shielding positioning mechanism 7 is provided with a plurality of shielding sleeves 702 distributed at equal intervals along the transverse direction; and a longitudinal adjustment mechanism 4, the longitudinal adjustment mechanism 4 is connected to a lifting mechanism 5, the lifting mechanism 5 being detachably connected to the shielding positioning mechanism 7 through a connecting mechanism 6.

[0034] like Figure 1-2 As shown, the clamping mechanism 3 includes a pressure plate 304; the pressure plate 304 is located inside the frame 1, a first guide post 305 is fixedly connected to the surface of the pressure plate 304, and a first threaded rod 302 is rotatably connected to the pressure plate 304. A nut seat 301 is threadedly connected to the first threaded rod 302, and a guide sleeve 306 is sleeved on the first guide post 305. The guide sleeve 306 and the nut seat 301 are both fixedly installed on the outer wall of the frame 1. A rotating disk 303 is fixedly installed at the end of the first threaded rod 302, and several anti-slip patterns are evenly arranged around the rotating disk 303.

[0035] When welding the stud 9, the plate 8 is placed inside the frame 1, so that the plate 8 is in contact with the inner wall of the right side and the inner wall of the rear side of the frame 1. Then, the rotating disks 303 of the two clamping mechanisms 3 are rotated in the forward direction in sequence, so that the first threaded rod 302 rotates. The first threaded rod 302 and the nut seat 301 are screwed together. With the guidance of the guide sleeve 306 and the first guide post 305, the pressure plate 304 presses the plate 8, providing positioning for the plate 8.

[0036] After the stud 9 is welded, the rotating disc 303 of the two clamping mechanisms 3 is turned in the opposite direction to separate the pressure plate 304 from the plate body 8 and release the positioning of the plate body 8.

[0037] like Figure 4-5 As shown, the shielding positioning mechanism 7 includes a strip frame 701; the shielding sleeve 702 is fixedly installed on the strip frame 701; a positioning groove 7011 is provided on one side wall of the strip frame 701. The connecting mechanism 6 includes a sleeve 601 fixedly installed on the top frame 502; a plug 602 is fixedly installed on the side wall of the sleeve 601, and a plug 603 is inserted into the plug 602. One end of the strip frame 701 with the positioning groove 7011 is inserted into the sleeve 601, and the plug 603 is inserted into the positioning groove 7011. A stop post 604 and a spring 605 are provided in one end of the sleeve 601; both the stop post 604 and the spring 605 are fixedly connected to the top frame 502, and both the stop post 604 and the spring 605 abut against the end of the strip frame 701.

[0038] Before welding, prepare multiple sets of shielding and positioning mechanisms 7. The arrangement of shielding sleeves 702 in the multiple sets of shielding and positioning mechanisms 7 is different. According to the welding requirements, select the required shielding and positioning mechanism 7 and replace the required shielding and positioning mechanism 7 on the connecting mechanism 6.

[0039] The specific replacement procedure is as follows: Pull the insert 603 to remove it from the positioning groove 7011. After removal, the compression force of the spring 605 pushes the strip frame 701 to move a certain distance. Then, pull the strip frame 701 to remove it from the sleeve 601. Next, install the required blocking positioning mechanism 7 by inserting the end of its strip frame 701 into the sleeve 601. During insertion, compress the spring 605 until the end of the strip frame 701 abuts against the stop post 604, and the positioning groove 7011 aligns with the insert 603. Push the insert 603 to insert it into the positioning groove 7011, completing the installation.

[0040] In the installed state, the spring force of the spring 605 provides abutment and clamping to the strip frame 701, and the insertion post 603 is inserted into the positioning groove 7011 for positioning.

[0041] like Figure 3 As shown, the longitudinal adjustment mechanism 4 includes a frame 401; a guide rail 402 is fixedly installed inside the frame 401, a second threaded rod 404 is rotatably installed inside the frame 401, a movable seat 405 is slidably installed on the guide rail 402, and a screw hole is opened on the movable seat 405, the screw hole is threadedly connected to the second threaded rod 404, a motor 403 is fixedly installed at one end of the frame 401, and the output shaft end of the motor 403 is fixedly connected to the end of the second threaded rod 404.

[0042] A support frame 2 is fixedly installed at the bottom of the frame 1, and the support frame 2 is fixedly connected to the frame 401.

[0043] like Figure 3 As shown, the lifting mechanism 5 includes an electric push rod 501; the electric push rod 501 is fixedly connected to the movable seat 405, and a top frame 502 is fixedly connected to the top end of the output shaft of the electric push rod 501. A side frame 503 is fixedly installed on the outer shell of the electric push rod 501, and a guide hole is provided on the side frame 503. A second guide post 504 is connected to the guide hole with clearance fit, and the top end of the second guide post 504 is fixedly connected to the top frame 502.

[0044] After replacing the required shielding positioning mechanism 7, the electric push rod 501 is used to adjust the height so that the shielding sleeve 702 fits against the top surface of the plate 8. Then, the longitudinal position of the shielding positioning mechanism 7 is adjusted by the longitudinal adjustment mechanism 4 until it is adjusted to the required position.

[0045] The longitudinal adjustment is as follows: the motor 403 drives the second threaded rod 404 to rotate, and the second threaded rod 404 is screwed into the threaded hole. With the guide rail 402 providing guidance for the movable seat 405, the movable seat 405 drives the lifting mechanism 5 and the blocking and positioning mechanism 7 to move longitudinally together.

[0046] After longitudinal adjustment, the welding torch carrying the stud 9 is inserted into all the shielding sleeves 702 in sequence to weld the stud 9. After welding is completed, as shown... Figure 1 As shown, the lifting mechanism 5 drives the blocking and positioning mechanism 7 to move upward, move it above the stud 9 to achieve separation, and then release the clamping of the plate 8 so that the plate 8 can be removed.

[0047] It should be noted that the shielding sleeve 702 is horn-shaped, with the top port used for the insertion of the welding torch end for positioning. Welding is performed in the positioned state. At the same time, after the welding torch end is inserted, the shielding sleeve 702 provides shielding for the welding position to prevent spatter.

The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
