Description

Technical Field

[0001] This utility model relates to the technical field of rail transit welding, and in particular to a fixture for welding and flipping rail transit vehicle bodies. Background Technology

[0002] In the actual production process, the remaining parts are welded onto the rail transit vehicle body parts by a welding device. The welding device includes a workbench with clamps for fixing the vehicle body parts. The vehicle body parts are moved to the workbench by a forklift or hoisting and then fixed to the workbench by the clamps.

[0003] In subsequent use, it was found that the fixtures in the existing technology are fixed on the worktable. When welding parts on the other side of the vehicle body parts, it is necessary to re-fix the vehicle body parts or for the operator to carry tools to the other side of the vehicle body parts for welding, which affects the welding efficiency of the vehicle body parts. Utility Model Content

[0004] To improve the welding efficiency of vehicle body components, this application provides a fixture for welding and flipping rail transit vehicle bodies.

[0005] This application provides a welding and flipping fixture for rail transit vehicle bodies, which adopts the following technical solution: A fixture for welding and flipping rail transit vehicle bodies includes a worktable with two control seats symmetrically arranged on both sides of the center line of the worktable. The control seats are slidably mounted on the worktable, and a clamping assembly for clamping vehicle body components is rotatably mounted on the control seats. A control block for providing support to the clamping assembly is also provided on the control seats. The clamping assembly includes a clamping block rotatably mounted on a control block. The control block is provided with a rotating component for driving the clamping block to rotate. The clamping block is provided with a fixed clamping block and a movable clamping block that cooperate with each other. The movable clamping block is slidably mounted on the clamping block. The clamping block is provided with a control component for controlling the sliding of the movable clamping block.

[0006] By adopting the above technical solution, after the car body component is fixed by the clamping assembly located on the control seat, the clamping block can be rotated by the rotating component, which in turn drives the car body component to rotate. The rotation angle of the car body component can be controlled according to the actual welding needs, reducing the movement of the operator and improving the welding efficiency of rail transit car body components to a certain extent.

[0007] Preferably, the clamping block has a sliding groove for sliding the movable clamping block, the control component includes a clamping screw rotatably disposed on the clamping block, the clamping screw is located in the sliding groove, one end of the clamping screw passes through the clamping block, the movable clamping block has a clamping threaded hole that cooperates with the clamping screw, and the clamping block has a clamping member for controlling the rotation of the clamping screw.

[0008] By adopting the above technical solution, when the clamping screw is rotated by the clamping component, the moving clamping block can slide down under the action of the thread transmission to cooperate with the fixed clamping block to clamp the vehicle body component. The amount of sliding of the moving clamping block can be controlled, and the thread has self-locking properties, which ensures the reliability of the cooperation between the moving clamping block and the fixed clamping block to fix the vehicle body component.

[0009] Preferably, the control block is slidably disposed on the control seat, the control seat has a control groove for sliding the control block, a control screw is rotatably connected to the control seat, the control block has a through control thread hole that is threaded to the control screw, the control screw is located in the control groove, one end of the control screw passes through the control seat, and the control seat has a control component for controlling the rotation of the control screw.

[0010] By adopting the above technical solution, when the control screw rotates under the action of the control component, the control block can have displacement relative to the worktable under the action of the threaded transmission, thereby adjusting the distance between the car body component and the worktable, so that the car body component is not easy to contact the worktable during the process of the clamping assembly driving the car body component to rotate.

[0011] Preferably, the control base is provided with a positioning slider, and the control block is provided with a positioning groove that cooperates with the positioning slider.

[0012] By adopting the above technical solution, the stability of the control block sliding is improved through the cooperation of the positioning slider and the positioning groove.

[0013] Preferably, both the moving clamp and the fixed clamp are provided with friction-enhancing pads, and the friction-enhancing pads are elastic.

[0014] By adopting the above technical solution and setting the friction-enhancing pad, the friction between the moving clamp block, the fixed clamp block, and the vehicle body parts is effectively increased, thereby improving the reliability of fixing the vehicle body parts by the clamping assembly. Furthermore, the elastic setting of the friction-enhancing pad allows the clamping assembly to adapt to vehicle body parts with different side shapes, thus increasing the applicability of the welding device to a certain extent.

[0015] Preferably, both the moving clamp block and the fixed clamp block are provided with guide slopes.

[0016] By adopting the above technical solution, the guide ramp provides guidance for the process of the vehicle body component sliding between the moving clamping block and the fixed clamping block, thereby reducing the collision between the vehicle body component and the clamping assembly.

[0017] In summary, this application includes at least one of the following beneficial technical effects: 1. After the car body component is fixed by the clamping assembly located on the control seat, the clamping block can be rotated by the rotating component, which in turn can drive the car body component to rotate. The rotation angle of the car body component can be controlled according to the actual welding needs, reducing the movement of the operator and improving the welding efficiency of rail transit car body components to a certain extent. 2. By setting the friction-enhancing pad, the friction between the moving clamp block, the fixed clamp block, and the vehicle body parts is effectively increased, which improves the reliability of fixing the vehicle body parts by the clamping assembly. Furthermore, the elastic setting of the friction-enhancing pad allows the clamping assembly to adapt to vehicle body parts with different side shapes, which to a certain extent increases the applicability of the welding device.

[0022] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0023] This application discloses a fixture for welding and flipping rail transit vehicle bodies, referring to... Figure 1 and Figure 2The system includes a workbench 1, on which two control seats 2 are provided. The two control seats 2 are symmetrically arranged on both sides of the center line of the workbench 1. The control seats 2 are provided with clamping components 3 for clamping vehicle body parts. The control seats 2 are provided with control blocks 21 for providing support for the clamping components 3. The clamping components 3 include clamping blocks 31 rotatably disposed on the control blocks 21. The clamping blocks 31 are provided with fixed clamping blocks 33 and movable clamping blocks 32 that cooperate with each other to clamp the vehicle body parts. The movable clamping blocks 32 are slidably disposed on the clamping blocks 31. After the movable clamping blocks 32 slide toward the fixed clamping blocks 33, they can cooperate with the fixed clamping blocks 33 to clamp the vehicle body parts. The control block 21 is equipped with a rotating component for driving the clamping block 31 to rotate. In this embodiment, the rotating component is a rotary motor 34, which is fixed on the control block 21. The output shaft of the rotary motor 34 is coaxially fixed with the clamping block 31. By driving the clamping block 31 to rotate through the rotary motor 34, the vehicle body component can be rotated. The angle of rotation of the vehicle body component can be controlled according to the actual welding needs, reducing the movement of the operator and improving the welding efficiency of the rail transit vehicle body component to a certain extent.

[0024] Reference Figure 1 and Figure 2 The clamping block 31 is provided with a control component for controlling the sliding of the movable clamping block 32. The clamping block 31 has a sliding groove 311 for the movable clamping block 32 to slide. The control component includes a clamping screw 35 rotatably mounted on the clamping block 31. The clamping screw 35 is located in the sliding groove 311, and one end of the clamping screw 35 passes through the clamping block 31. The movable clamping block 32 has a clamping threaded hole that mates with the clamping screw 35. The clamping block 31 is provided with a clamping member for controlling the rotation of the clamping screw 35. When the clamping screw 35 is rotated by the clamping component, the moving clamping block 32 can slide under the action of the threaded transmission. The clamping component can be a control button or a clamping motor 351. If the clamping component is a control button, the clamping screw 35 needs to be slid by manual control. Although it is cumbersome, it allows manual control of the force of the moving clamping block 32 and the fixed clamping block 33 in clamping the column body component, and the body component is not easily damaged. However, in this embodiment, the clamping component is a clamping motor 351, which effectively improves the automation level of the welding device.

[0025] Reference Figure 1 and Figure 3The control seat 2 is slidably mounted on the workbench 1. When the vehicle body parts are moved between the two control seats 2 by means of hoisting or forklift, the clamping assembly 3 located on the control seat 2 can clamp the vehicle body parts by means of the sliding of the control seat 2. The workbench 1 is provided with an adjustment groove 11 for the sliding of the control seat 2. An adjustment screw 12 is rotatably connected to the workbench 1. One end of the adjustment screw 12 passes through the workbench 1 and is located in the adjustment groove 11. The control seat 2 is provided with an adjustment thread hole that is threadedly engaged with the adjustment screw 12. When the threads of the adjustment screws 12 that are threadedly engaged with the two control seats 2 are rotated in opposite directions, the control seats 2 can slide towards or away from each other under the action of the thread transmission when the adjustment screw 12 rotates. An adjustment motor 13 for driving the adjustment screw 12 to rotate is fixed on the workbench 1. The output shaft of the adjustment motor 13 is coaxially fixed with the adjustment screw 12.

[0026] Reference Figure 1 Both the moving clamping block 32 and the fixed clamping block 33 are provided with friction-enhancing pads 36. The friction-enhancing pads 36 are elastic. In this embodiment, the friction-enhancing pads 36 are made of rubber. By setting the friction-enhancing pads 36, the friction between the moving clamping block 32 and the fixed clamping block 33 and the vehicle body parts is effectively increased, which improves the reliability of fixing the vehicle body parts by the clamping assembly 3. The elastic setting of the friction-enhancing pads 36 allows the clamping assembly 3 to adapt to vehicle body parts with different side shapes, which increases the applicability of the welding device to a certain extent.

[0027] Reference Figure 1 Both the movable clamping block 32 and the fixed clamping block 33 are provided with guide slopes 37. The guide slopes 37 are provided to guide the process of the vehicle body component sliding between the movable clamping block 32 and the fixed clamping block 33, thereby reducing the collision between the vehicle body component and the clamping assembly 3.

[0028] Reference Figure 1 and Figure 2 The control block 21 is slidably mounted on the control base 2. The control base 2 has a control groove 211 for sliding the control block 21. A control screw 22 is rotatably connected to the control base 2. A control threaded hole for threaded engagement with the control screw 22 is provided through the control block 21. The control screw 22 is located in the control groove 211, and one end of the control screw 22 passes through the control base 2. The control base 2 has a control component for controlling the rotation of the control screw 22. When the control component rotates under the action of the control screw 22, the control block 21 can have displacement relative to the worktable 1 under the action of threaded transmission, thereby adjusting the distance between the vehicle body component and the worktable 1, so that the vehicle body component is less likely to contact the worktable 1 during the rotation of the clamping assembly 3. In this embodiment, the control component is a control motor 23, which is fixed on the control base 2. The output shaft of the control motor 23 is coaxially fixed with the control screw 22.

[0029] Reference Figure 1 and Figure 3 The control base 2 is provided with a positioning slider 24, and the control block 21 is provided with a positioning groove that cooperates with the positioning slider 24. The positioning slider 24 can be set in a dovetail shape. The cooperation between the positioning slider 24 and the positioning groove improves the stability of the sliding of the control block 21.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
