Description

Technical Field

[0001] The invention relates to the technical field of welding fixture devices, in particular to a gear box welding device. Background Art

[0002] The gearbox is an important mechanical transmission component, widely used in various industrial equipment and vehicles. Its main body uses a series of carefully designed gear pairs (including cylindrical gears, bevel gears, worm gears, etc.) to achieve functions such as transmitting power, changing torque and rotation speed (i.e. decelerating or increasing speed).

[0003] At present, there are many methods for making gearboxes in the prior art. Generally, small gearboxes are cast, while medium and large gearboxes need to be made using welding technology. Among them, in the process of manufacturing or repairing gearboxes, when welding devices are used to connect or repair their parts, the gearbox is generally placed in the middle of the bracket of the welding equipment and fixed by a clamping device that can be fixed in the center. However, there are still some shortcomings in its actual use. For example, although there are fixture designs for gearbox welding on the market, such fixtures often use basic flat clamps to fix the two sides of the gearbox. Once they encounter gearboxes of various sizes and shapes (cylindrical, square and other external structures), their limitations are obvious. Due to the weak adaptability of the fixture, the adjustment mechanism is not flexible enough, and the weight distribution of the gearbox itself affects the fixing effect, which is unsatisfactory and the stability is greatly reduced. This series of factors have a chain reaction, which ultimately hinders the accuracy and efficiency of production and becomes a bottleneck for improving product quality and production capacity. Therefore, a gearbox welding device is proposed to solve the above problems. Summary of the invention

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the present invention provides a gear box welding device, which has the following beneficial effects:

[0020] 1. The present invention uses structures such as clamping components to control the extension or contraction of the electric push rod 1 according to the actual size specifications of the gear box before the welding process of the gear box, and the front clamping plate and the rear clamping plate fixed at both ends of the electric push rod 1 slide upward or downward relative to each other, so that the heights of the two are adapted to the gear box. Then, after the staff places the gear box in the middle of the two symmetrically arranged clamping mechanisms, the displacement mechanism is controlled to make the two sets of clamping mechanisms approach each other until the surface of the front clamping plate fits the outer surface of the gear box, and the outer walls of the gear box on both sides are clamped. Finally, the electric push rod 2 can be controlled to extend, and the U-shaped blocks connected at both ends can be pushed to move in the direction away from the electric push rod 2, pulling The rotatably connected connecting rod deflects with the U-shaped block sleeved in the middle as the center of the circle, and the connecting rod drives the movable clamping claw connected to the U-shaped block arranged away from the two ends of the electric push rod to rotate along the bottom end of the rear clamping plate or the top end of the front clamping plate, so that the two movable clamping claws arranged horizontally with the rear clamping plate are adjusted to fit the upper and lower surfaces of the gear box, so as to flexibly adjust the actual length of the clamping mechanism according to actual processing requirements to meet the clamping requirements of gear boxes of various specifications, and use the adjusting tool to support the upper and lower outer walls of the gear box with the movable clamping claw to improve the stability of the clamping and fixing of the gear box, with high adjustment flexibility and good supporting effect, so as to ensure the stability and accuracy of subsequent processing;

[0021] 2. The present invention uses structures such as a rotating assembly and a flipping mechanism. During the welding operation, for the clamped gear box, the worker can control the motor 4 to start, and the main gear connected to the output end of the motor 4 rotates. The slave gear meshing with the main gear rotates, driving the fixed column sleeved in the middle to rotate along the top inner wall of the movable rod, driving the connected rear clamping plate and other structures to rotate, so that the gear box clamped by the clamping mechanism is rotated, and the end of the clamping mechanism symmetrically arranged on the other side is pulled to rotate, so as to realize the flipping operation of the gear box. In addition, the motor 2 can be controlled to start, and the slave gear meshing with the motor 2 can be controlled to start. The worm connected to the output end rotates along the inner surface of the fixed plate, driving the external meshing worm wheel to rotate. The connecting column fixedly installed on the top of the worm wheel rotates along the inner wall of the chassis and the processing table. At the same time, the supporting plate connected to the top rotates inside the top of the processing table, driving the clamping assembly set on the top of the supporting plate and the gear box clamped by the clamping assembly to adjust the angle. The above structure can be used to adjust the angle and turn over the gear box to achieve welding or ring welding processing at different positions of the gear box, further improving the flexibility of the gear box welding process and improving the practicality of the equipment.

[0022] 3. The present invention uses structures such as a welding gun adjustment component. In the actual processing process, the position of the welding gun body can be adjusted by the welding gun adjustment component. The control motor is started, and the gear connected to the output end of the motor rotates in the middle of the U-shaped slider and moves along the surface of the meshing sawtooth strip plate, pulling the U-shaped slider to slide along the outer surface of the sawtooth strip plate. The frame plate fixed on the top of the U-shaped slider moves laterally together with the U-shaped slider to adjust the lateral direction of the welding gun body. By controlling the extension or contraction of the hydraulic cylinder, the connected movable plate is pushed to slide up and down along the inside of the frame plate to weld. The height direction of the gun body is adjusted by controlling the extension or contraction of the hydraulic cylinder 2 to push the connected socket block to slide along the outer surface of the limit frame, driving the welding gun body socketed in the middle to move longitudinally to adjust the longitudinal direction of the welding gun body. The welding gun adjustment assembly is adjusted to facilitate the linear position movement of the socketed welding gun body in the horizontal and vertical directions, and the height of the welding gun body can be adjusted according to the size of different gear boxes, so that the welding gun body can be welded horizontally along the gear box, thereby improving the welding efficiency of the equipment.
