[0002] In the process of mechanical processing, product inspection, assembly and welding, a large number of process equipment, referred to as tooling, are used to install the processing object so that it occupies the correct position to ensure the quality of parts and products and improve productivity.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: most of the existing common tooling is specially designed for the assembly welding process of a certain welding assembly, and is a non-standard device. It is often necessary for each manufacturer to design and manufacture it according to the structural characteristics, production conditions and actual needs of the product, which is not conducive to improving the practicality of the device. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a rear frame welding tool.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions: a rear frame welding tool, including a base plate, two mutually symmetrical first clamping devices are symmetrically arranged on the upper surface of the base plate, a second clamping device is arranged on the upper surface of the base plate, a slide groove is opened on the upper surface of the base plate, two sliders are slidably arranged in the slide groove, the two sliders are respectively connected to the two first clamping devices, a threaded rod is rotatably arranged on the side wall of the base plate, the threaded rod is rotatably connected to the inner wall of the rotating groove, the threads at both ends of the threaded rod are opposite, and the threaded rod is threadedly connected to the two sliders.

[0006] By adopting the above technical solution, when the staff needs to weld the rear frame, the staff needs to fix the rear frame through the first clamping device and the second clamping device. Subsequently, the staff welds the fixed rear frame through a robot arm or manually. During this process, when the staff needs to weld rear frames of different models, the staff needs to rotate the threaded rod, so that the two sliders slide in a direction away from or close to each other under the action of the threaded rod, so that the first clamping device moves in a direction away from or close to each other under the action of the slider, and the angle of the first clamping device changes, so that rear frames of different models can be fixed, thereby improving the practicality of the device.

[0007] Furthermore, a rotation groove is provided on the upper surface of the sliding block, a rotation rod is rotatably arranged in the rotation groove, a rubber layer is sleeved on the outer wall of the rotation rod, and the rotation rod and the first clamping device are fixed to each other.

[0008] By adopting the above technical solution, when the angle of the rear frame is different, the staff needs to rotate the rotating rod, so that the first clamping device rotates under the action of the rotating rod, so that the angle of the first clamping device changes, and then the rear frames of different models can be fixed. In this process, the rubber layer increases the maximum static friction force between the rotating rod and the rotating groove, thereby reducing the probability of the rotating rod rotating due to external force, thereby improving the stability of the device.

[0009] Furthermore, the first clamping device includes a fixed plate fixedly arranged on the upper surface of the slider, two arc-shaped plates symmetrically arranged on the upper surface of the fixed plate, two clamping springs respectively fixedly arranged on the side walls of the two arc-shaped plates close to each other, and two first clamping plates respectively fixedly arranged on one end of the two clamping springs away from the arc-shaped plates, and the upper surface of the rotating rod and the bottom surface of the fixed plate are fixed to each other.

[0010] By adopting the above technical solution, when the staff needs to fix the rear frame through the first clamping device, the staff needs to install one end of the rear frame between the two first clamping plates. During this process, the first clamping plate presses against the rear frame under the action of the clamping spring, thereby fixing the rear frame with the first clamping plate.

[0011] Furthermore, the second clamping device includes a mounting plate fixedly arranged on the upper surface of the base plate, the upper surface of the mounting plate is symmetrically provided with rotation grooves, and the second clamping device also includes two rotating rods respectively rotatably arranged in the two rotation grooves and two second clamping plates respectively fixedly arranged on the upper surfaces of the two rotating rods.

[0012] By adopting the above technical solution, when the staff needs to fix the rear frame by the second clamping device, the staff needs to rotate the second clamping plate to rotate the rotating rod. Then, the staff installs the other end of the rear frame between the two second clamping plates to fix the rear frame by the second clamping plates.

[0013] Furthermore, reset grooves are provided on the two inner walls of the rotating groove, torsion springs are fixedly provided on the inner walls of the two reset grooves, and the other ends of the two torsion springs are respectively fixedly provided on the side walls of the rotating rod.

[0014] By adopting the above technical solution, when the staff installs the other end of the rear frame between the two second clamping plates, the rotating rod rotates under the action of the torsion spring, and then the second clamping plate rotates under the action of the rotating rod, so that the second clamping plate presses against the other end of the rear frame, thereby reducing the probability of shaking of the rear frame.

[0015] Furthermore, anti-slip pads are fixedly provided on the side walls of the first clamping plate and the second clamping plate.

[0016] By adopting the above technical solution, the anti-skid pad increases the upper limit of the maximum static friction between the first clamping plate and the second clamping plate and the rear frame, thereby reducing the probability of shaking of the rear frame during welding, and further improving the stability of the device.

[0017] Furthermore, a rocker arm is fixedly arranged on the side wall of the threaded rod.

[0018] By adopting the above technical solution, the rocker arm reduces the difficulty for the staff to rotate the threaded rod, thereby reducing the working difficulty of the staff.

[0019] Furthermore, rubber pads are fixedly arranged at the four corners of the bottom surface of the base plate.

[0020] By adopting the above technical solution, when the staff places the bottom plate on the carrier, the rubber pad reduces the probability of the bottom plate sliding, thereby improving the stability of the device.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. In this application, when the staff needs to weld the rear frame, the staff needs to fix the rear frame through the first clamping device and the second clamping device. Afterwards, the staff welds the fixed rear frame through a robot arm or manually. During this process, when the staff needs to weld rear frames of different models, the staff needs to rotate the threaded rod, so that the two sliders slide away from or towards each other under the action of the threaded rod, so that the first clamping device moves away from or towards each other under the action of the slider, and the angle of the first clamping device changes, so that rear frames of different models can be fixed, thereby improving the practicality of the device;

[0023] 2. In the present application, when the angles of the rear frame are different, the staff needs to rotate the rotating rod, thereby causing the first clamping device to rotate under the action of the rotating rod, so that the angle of the first clamping device changes, and the rear frames of different models can be fixed. In this process, the rubber layer increases the upper limit of the maximum static friction between the rotating rod and the rotating groove, thereby reducing the probability of the rotating rod rotating due to external force, thereby improving the stability of the device;

[0024] 3. In the present application, when the staff needs to fix the rear frame by the first clamping device, the staff needs to install one end of the rear frame between the two first clamping plates. During this process, the first clamping plate presses against the rear frame under the action of the clamping spring, thereby fixing the rear frame by the first clamping plate.

The threads at both ends of the threaded rod 12 are opposite, and the threaded rod 12 is threadedly connected to the two sliders 11.

[0033] When the staff needs to weld the rear frame, the staff needs to fix the rear frame through the first clamping device 4 and the second clamping device 5. Then, the staff welds the fixed rear frame through the robot arm or manually. In this process, when the staff needs to weld rear frames of different models, the staff needs to rotate the threaded rod 12, so that the two sliders 11 slide in the direction of moving away from or approaching each other under the action of the threaded rod 12, so that the first clamping device 4 moves in the direction of moving away from or approaching each other under the action of the slider 11, so that the angle of the first clamping device 4 changes, so that rear frames of different models can be fixed, thereby improving the practicality of the device.

[0034] The upper surface of the slider 11 is provided with a rotation groove 21, and the rotation rod 3 is a round rod structure with a vertical axis, and the rotation rod 3 is rotatably arranged in the rotation groove 21. The rubber layer 31 is sleeved on the outer wall of the rotation rod 3, and the rotation rod 3 and the first clamping device 4 are fixed to each other.

[0035] When the angles of the rear frame are different, the staff needs to rotate the rotating rod 3, so that the first clamping device 4 rotates under the action of the rotating rod 3, so that the angle of the first clamping device 4 changes, and then the rear frames of different models can be fixed. In this process, the rubber layer 31 increases the maximum static friction force between the rotating rod 3 and the rotating groove 21, thereby reducing the probability of the rotating rod 3 rotating due to external force, thereby improving the stability of the device.

[0036] The first clamping device 4 is provided with two and symmetrically arranged on the upper surface of the base plate 1, and the first clamping device 4 includes a fixed plate 41, an arc plate 42, a clamping spring 43 and a first clamping plate 44.
