[0013] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0014] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0015] See also Figures 1 to 3 , provided in one embodiment of the utility model, is a rear suspension bracket assembly welding robot fixture, comprising a housing 101, and further comprising:

[0016] A leveling component 2, used to control the bracket to be on the same horizontal line;

[0017] The leveling assembly 2 includes a screw 201, a slide A202 and a cross bar 203. The screws 201 are rotatably connected in the two shells 101 respectively, and the slides A202 are threadedly connected on the two screws 201 respectively. The slide A202 is slidably connected to the shell 101 through a slide groove in the shell 101, and a cross bar 203 is fixedly connected between the two slides A202.

[0018] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, they are not limited to the specific screw rod 201 described in the above embodiments. For example, the screw rod 201 can be replaced with a reciprocating screw rod. The purpose of this arrangement is that when the slide A202 and the slide B204 threaded thereon move to one end, the screw rod 201 can be controlled to continue to rotate, thereby quickly changing the movement direction of the slide A202 and the slide B204.

[0019] Specifically, a slide cylinder B204 is threadedly connected to the screw rod 201 , and the slide cylinder B204 is slidably connected to the housing 101 through a slide groove in the housing 101 .

[0020] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, they are not limited to the specific slide A202 and slide B204 described in the above embodiments. For example, damping rubber strips are provided at the connection between the slide A202 and the slide B204 and the shell 101. The purpose of this setting is to facilitate smooth sliding in this way and effectively prevent abnormal noise during sliding.

[0021] Specifically, a plurality of push rods 206 are hinged on the slide cylinder B204 , and the other ends of the plurality of push rods 206 are hinged on the support rods 205 , respectively.

[0022] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, they are not limited to the specific top rod 206 described in the above embodiments. For example, the top rod 206 should be made of a one-piece processed material. The purpose of this setting is to prevent the top rod 206 from breaking under stress, thereby preventing it from being able to provide normal supporting force.

[0023] Specifically, one end of the plurality of support rods 205 is hinged to the housing 101 , and the other end of the support rods 205 is hinged to a base 207 , and spikes are provided at the bottom of the base 207 .

[0024] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, they are not limited to the specific base 207 described in the above embodiments. For example, a pulley may be provided at the bottom of the base 207. The purpose of this arrangement is to facilitate the movement of the device as a whole in this way.

[0025] Specifically, a gear 208 is fixedly connected to the screw rod 201 , and the gear 208 is meshedly connected with an output gear of a motor 209 . The motor 209 is fixedly connected in the housing 101 .

[0026] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, they are not limited to the specific motor 209 described in the above embodiments. For example, the motor 209 should be a motor with multiple adjustable speeds. The purpose of this setting is to facilitate adjusting the speed of the screw 201 by adjusting the speed of the output gear of the motor 209.

[0027] Specifically, a main shaft 301 is rotatably connected in the transverse groove of the transverse rod 203 , and a shaft disc 305 is fixedly connected to one end of the main shaft 301 .

[0028] For the above examples, those skilled in the art should be aware that when implementing the above technical solution, they are not limited to the specific shaft disc 305 described in the above embodiment. For example, the shaft disc 305 is rotatably connected to a grip rod at an eccentric portion. The purpose of this arrangement is to facilitate the circular motion of the worm gear, thereby causing the shaft disc 305 to start rotating.

[0029] Specifically, a plurality of left-handed screw rods 302 and right-handed screw rods 303 are fixedly connected to the main shaft 301 , and a clamping plate 304 is threadedly connected to the left-handed screw rods 302 and the right-handed screw rods 303 , respectively. The clamping plate 304 is slidably connected to the cross bar 203 through a sliding groove on the cross bar 203 .

[0030] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, they are not limited to the specific splint 304 described in the above embodiments. For example, a soft anti-slip film may be provided on the inner side of the splint 304. The purpose of this provision is to increase the surface friction through the natural film, thereby preventing the splint 304 from sliding when clamping the bracket.

[0031] In the embodiment of the utility model, the relevant technicians start the motor 209, so that the motor 209 drives the gear 208 meshing with its output gear to start rotating, so that the gear 208 drives the screw rod 201 fixedly connected to it to start rotating, so that the screw rod 201 drives the slide cylinder A202 threaded thereon to start linear motion along the slide groove at the connection between it and the shell 101, so that the slide cylinder A202 drives the cross bar 203 fixed thereon to start synchronous linear motion, so that the cross bar 203 starts to approach the automobile chassis beam body, and at the same time, when the screw rod 201 starts to rotate, the screw rod 201 drives the slide cylinder B204 threaded thereon to start synchronous linear motion, so that the slide cylinder B204 starts to push the top rod 206 hinged thereto, so that the top rod 206 starts to push the support rod 205 hinged thereto to make it move with the hinged connection with the shell 101 as the fulcrum. The support rod 205 performs circular motion, thereby causing the support rod 205 to drive the base 207 hinged thereto to move synchronously. At this time, the relevant technical personnel prevent the device from being placed above the chassis beam, thereby contacting the bottom plate through the base 207 to support the device. When the bracket is installed on the cross bar 203, the device tilts, resulting in the bracket being unable to be welded to the same horizontal line. Subsequently, the relevant technical personnel place the bracket between the two clamping plates 304 and manually rotate the shaft disc 305 at the same time, so that the shaft disc 305 drives the main shaft 301 fixedly connected thereto to rotate synchronously, and the main shaft 301 drives the left-handed screw rod 302 and the right-handed screw rod 303 fixed thereon to start rotating synchronously, so that the two clamping plates 304 threadedly connected on the left-handed screw rod 302 and the right-handed screw rod 303 start to move toward each other, thereby starting to clamp the bracket with the cooperation of the two clamping plates 304, and welding and fixing can be started after the fixation is completed.
