[0013] Compared with the prior art, the utility model has the following beneficial effects: the anti-dislocation chain production welding machine not only improves the grinding effect after welding, but also simultaneously ensures the stability of welding;

[0014] (1) Through the guiding effect of the guide plate, the chains are welded one by one. At the same time, during the welding process, the laser welding head moves up and down, and the front and back reciprocating mechanism is used to use the limiting guide groove, guide rod and limiting guide hole to synchronously realize the reciprocating translation of the T-shaped grinding plate.

[0024] See also Figure 1-5 The utility model provides an embodiment: a dislocation-proof chain production welding machine, comprising a base 1, guide plates 2 are installed on both sides of the top of the base 1, and a U-shaped support 6 is installed on the top of the base 1 outside the guide plate 2, an electric telescopic rod 5 is installed on the top of the U-shaped support 6, and a lifting plate 4 is installed on the bottom of the electric telescopic rod 5;

[0025] The lifting plate 4 forms an up-and-down sliding structure with the U-shaped support 6 through the action of the guide block and the guide groove. The lifting plate 4 is located directly above the clamping mechanism 3. The clamping mechanism 3 is provided with two groups, and each group is provided with two, and each group is symmetrically distributed about the central axis of the base 1;

[0026] Specifically, Figure 1 , Figure 3 and Figure 4 As shown, the guide block and the guide groove are used to make the up and down movement direction of the lifting plate 4 more stable and limit its movement distance to avoid the laser welding head 11 being too close to the chain, causing excessive welding;

[0027] A laser welding head 11 is installed at the bottom end of the lifting plate 4, and clamping mechanisms 3 are evenly arranged at the top ends of the base 1 on both sides of the laser welding head 11;

[0028] The clamping mechanism 3 includes a support plate 301 installed at the top of the base 1 outside the guide plate 2, and a clamping plate 302 is installed on the side of the support plate 301 close to the guide plate 2, and a pressure plate 303 is installed on the top of the clamping plate 302;

[0029] The top of the clamping plate 302 is hinged to one side of the supporting plate 301, and the angle between the clamping plate 302 and the pressure plate 303 is greater than 90° and less than 180°;

[0030] Specifically, Figure 1 , Figure 3 and Figure 5As shown, when in use, the clamping plate 302 and the pressure plate 303 cooperate with each other, so that when the lifting plate 4 descends, the pressure plate 303 is squeezed to drive the clamping plate 302 to flip downward, so as to press and fix the chain below, thereby ensuring the stability of the chain during welding, and the clamping effect is linked with the welding process, and the effect is stable;

[0031] A U-shaped slide rail 10 is installed on the top of the base 1, and a T-shaped polishing plate 7 is sleeved on the outside of the U-shaped slide rail 10;

[0032] The T-shaped grinding plate 7 forms a forward and backward sliding structure with the base 1 through the action of the U-shaped slide rail 10, and the cross section of the guide hole 8 is perpendicular to the cross section of the limiting guide hole 905;

[0033] Meanwhile, the T-shaped grinding plate 7 is located above the guide plate 2, a guide hole 8 is opened inside the T-shaped grinding plate 7, and a front-rear reciprocating mechanism 9 is arranged inside the guide hole 8;

[0034] The front-to-back reciprocating mechanism 9 includes a guide rod 901 that passes through the guide hole 8, and a limit plate 903 is installed on the top of the base 1 at one end of the guide rod 901, and a limit guide groove 902 is provided on the side of the limit plate 903 close to the T-shaped grinding plate 7, and one end of the guide rod 901 extends to the inside of the limit guide groove 902, and a U-shaped guide frame 904 is installed on one side of the lifting plate 4 at the other end of the guide rod 901, and a limit guide hole 905 is provided inside the U-shaped guide frame 904, and the other end of the guide rod 901 passes through the limit guide hole 905 and extends to the inside of the lifting plate 4;

[0035] One end of the guide rod 901 forms a front-to-rear sliding structure with the lifting plate 4 through the action of the slider and the slide groove, the cross section of the limiting guide groove 902 is inclined, and the other end of the guide rod 901 forms an inclined sliding structure with the limiting plate 903 through the action of the movable block and the limiting guide groove 902;

[0036] Specifically, Figure 1 , Figure 2 and Figure 4 As shown, when in use, under the action of the slider slot, U-shaped guide frame 904, limit guide slot 902, etc., the movement of the guide rod 901 is guided, so that the guide rod 901 moves downward at an angle during the descending process of the lifting plate 4, and then finally realizes the horizontal reciprocating action of the T-shaped grinding plate 7, so that the T-shaped grinding plate 7 can stably grind the chain welding point.

[0037] Working principle: When the utility model is in use, first place the chain between the two guide plates 2 on the base 1, and push the chain to the right. When the chain is located directly below the laser welding head 11, start the electric telescopic rod 5 to extend, so that the lifting plate 4 drives the laser welding head 11 to descend. During the falling process of the lifting plate 4, it contacts and pushes one end of the pressure plate 303, so that the pressure plates 303 on both sides move inward and downward, and then the clamping plate 302 moves outward and downward, that is, the bottom end of the clamping plate 302 produces an oblique downward pressure on the chain below, and the multiple clamping plates 302 act to fix the chain, thereby ensuring the stability of the chain when the laser welding head 11 is welding;

[0038] Secondly, as the chains are welded one by one, the welded chains approach the bottom of the T-shaped grinding plate 7. During this process, the laser welding head 11 repeatedly moves up and down for welding. During the downward movement of the lifting plate 4, it synchronously drives the guide rod 901 to move. Since the two ends of the guide rod 901 are respectively limited and guided by the lateral limit guide hole 905 and the inclined limit guide groove 902, the guide rod 901 moves downward at an angle as the lifting plate 4 descends, and cooperates with the guide hole 8 to drive the T-shaped grinding plate 7 to move forward. As the lifting plate 4 rises, the T-shaped grinding plate 7 moves backward, that is, the T-shaped grinding plate 7 moves back and forth with the up and down welding process of the laser welding head 11, thereby rubbing the welding points on the chain passing below to achieve a smoothing effect, thereby ensuring the aesthetics of the chain welding points.
