[0019] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0021] Embodiment 1, as Figure 1-Figure 4As shown, the utility model provides a clutch pedal assembly welding fixing device, including an operating table 1, a fixing adjustment mechanism 3 is arranged on the top of the operating table 1, a cooling mechanism 4 is arranged on the outer surface of the operating table 1, the fixing adjustment mechanism 3 includes a first motor 301, the output end of the first motor 301 slides through the outer surface of the operating table 1 and extends to one side, the output end of the first motor 301 is fixedly connected with a first threaded screw 302, the outer surface of the first threaded screw 302 is threadedly connected with a first movable block 303, a first sliding groove 304 is opened near the center of the top of the operating table 1, a moving plate 305 is fixedly connected to the top of the moving plate 305, a second sliding groove 306 is opened near the center of the top of the moving plate 305, and a second motor 3 is arranged on the outer surface of the moving plate 305. 07, the output end of the second motor 307 slides through the outer surface of the movable plate 305 and extends to one side, the output end of the second motor 307 is fixedly connected with a second threaded screw 308, the outer surface of the second threaded screw 308 is threadedly connected with a second movable block 309, the top of the second movable block 309 is fixedly connected with a U-shaped frame 310, the top of the U-shaped frame 310 is slidably connected with a clamping plate 311, one side of the clamping plate 311 is rotatably connected with a third threaded screw 312 near the center, one end of the third threaded screw 312 threads through the outer surface of the U-shaped frame 310 and extends to one side, one end of the third threaded screw 312 is provided with a nut 313, the outer surfaces of the U-shaped frame 310 and the clamping plate 311 on the opposite sides are provided with a silicone pad 314, the top of the U-shaped frame 310 is in contact with the bottom of the clamping plate 311.

[0022] The effect achieved by the entire embodiment 1 is that when using the present device, the clutch pedal assembly to be welded is first placed on the U-shaped frame 310. At this time, the nut 313 is manually rotated, so that the third threaded screw 312 can be driven to rotate when it rotates. When the third threaded screw 312 rotates, it can drive the clamping plate 311 to move left and right, so that the pedal assembly can be adjusted and clamped. When other positions of the welding pedal need to be adjusted, the first motor 301 is started, and the output end of the motor drives the first threaded screw 302 to rotate. When the first threaded screw 302 rotates, its spiral thread pushes the first movable block 303 to move along the axial direction, and under the action of the first sliding groove 304, the movable block 303 is moved along the axial direction. The movable plate 305 can move forward and backward, and the second motor 307 is started to drive the second threaded screw 308 to rotate with its output end. When the second threaded screw 308 rotates, its spiral thread will push the second movable block 309 to move in the axial direction, and under the action of the second sliding groove 306, the U-shaped frame 310 can move left and right. Under the action of the fixed adjustment mechanism 3, the welding position can be flexibly adjusted, which effectively avoids the limitation of the welding gun only welding at a single position, thereby avoiding the trouble of frequently adjusting the welding gun position when changing the welding position. The design mechanism is simple, which not only improves the applicability, but also improves the work efficiency. The silicone pad 314 is mainly used to prevent the pedal from falling off during the clamping process.

[0023] Embodiment 2, as Figure 1-Figure 4 As shown, the cooling mechanism 4 includes a ventilation duct 401, a refrigerator 402 is arranged on the outer surface of the ventilation duct 401, one end of the ventilation duct 401 is fixedly connected to an air pump 404, a fixed plate 403 is fixedly installed at the bottom of the air pump 404, a plurality of vents 405 are arranged at the inner top of the fixed plate 403, the air pump 404 is connected to the vents 405, a plurality of support columns 2 are arranged at the bottom of the operating table 1 near the four corners, the top of the first movable block 303 is fixedly connected to the bottom of the movable plate 305, the top of the second movable block 309 is fixedly connected to the bottom of the U-shaped frame 310, the refrigerator 402 is fixedly installed on the outer surface of the fixed plate 403, and the outer surface of the operating table 1 is fixedly connected to the inner surface wall of the fixed plate 403.

[0024] The effect achieved by the entire embodiment 2 is that when the pedal generates high temperature after welding is completed, the air pump 404 on the fixed plate 403 is used to drive the suction force to suck air into the interior of the ventilation duct 401, and under the action of the refrigerator 402, the air temperature inside the ventilation duct 401 is reduced, and finally the cold air is discharged through the vent 405 to cool the welded pedal, ensuring that the thermal stress generated during the welding process is released, effectively avoiding deformation and internal stress problems caused by high temperature, and the support column 2 is mainly used to support the operating table 1.

[0025] Working principle: When using the present device, first place the clutch pedal assembly to be welded on the U-shaped frame 310. At this time, manually turn the nut 313 to drive the third threaded screw 312 to rotate. When the third threaded screw 312 rotates, it drives the clamping plate 311 to move left and right, so that the pedal assembly can be adjusted and clamped. When other positions of the welding pedal need to be adjusted, start the first motor 301 to drive the first threaded screw 302 to rotate. When the first threaded screw 302 rotates, its spiral thread will push the first movable block 303 to move in the axial direction, and under the action of the first sliding groove 304, the movable plate 305 can move forward and backward, and start the second motor 307 to drive the second threaded screw 308 to rotate. When the second threaded screw 308 rotates, its spiral thread will push the second movable block 309 to move in the axial direction. The U-shaped frame 310 can move left and right under the action of the second sliding groove 306. Under the action of the fixed adjustment mechanism 3, the welding position can be flexibly adjusted, which effectively avoids the limitation of the welding gun only welding at a single position, thereby avoiding the trouble of frequently adjusting the welding gun position when changing the welding position. The design mechanism is simple, which not only improves the applicability but also improves the work efficiency. When the pedal generates high temperature after the welding is completed, the air pump 404 on the fixed plate 403 is used to drive the suction to suck air into the interior of the ventilation duct 401, and under the action of the refrigerator 402, the air temperature inside the ventilation duct 401 is reduced, and finally the cold air is discharged through the vent 405 to cool the pedal after the welding is completed, ensuring that the thermal stress generated during the welding process is released, effectively avoiding the deformation and internal stress problems caused by high temperature.

[0026] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
