Description

Shock absorber welding table Technical Field The invention relates to the field of welding equipment, in particular to a welding table of a shock absorber. Background Shock absorbers are a common component of a variety of vehicles used to cushion between the frame and the axle to attenuate the impact on the frame during travel of the vehicle, thereby protecting the frame and enhancing the ride experience. The working principle of the shock absorber is that the relative motion generated by vibration between the vehicle frame and the vehicle axle drives the piston of the shock absorber to move up and down, so that hydraulic oil in the oil storage cylinder of the shock absorber is driven to circulate repeatedly in the two oil cavities, and vibration energy is converted into heat energy of the hydraulic oil. Therefore, the oil storage cylinder is a core structure of the shock absorber, and when the shock absorber is installed, the piston end and the oil storage cylinder end are hinged with the frame or the axle, so that the end part of the oil storage cylinder is often welded with a hanging ring. The oil storage cylinder is a hollow cylindrical object with one end open, and the hanging ring is an annular object, so that two groups of wedge-shaped clamps which are vertically arranged are usually used in the prior art to position the oil storage cylinder and the hanging ring respectively before welding operation, and the oil storage cylinder and the hanging ring are axially adjusted to ensure alignment of the oil storage cylinder and the hanging ring before welding. Although the process of positioning the oil storage cylinder and the hanging ring by using the wedge-shaped clamp is simple, when small-scale factory is used for small-batch production, the specifications of the shock absorber are different, and when the specifications of the oil storage cylinder and the hanging ring are changed, the specifications of the wedge-shaped clamp are changed, so that the types of the wedge-shaped clamp are various, the cost of the welding table is increased, each replacement of the wedge-shaped clamp is adjusted experimentally, the replacement efficiency is difficult to ensure, and the working efficiency of the welding table is affected. For this purpose, a vibration damper welding station is proposed. Disclosure of Invention The invention aims to provide a welding table for a shock absorber, which solves the problem that a positioning clamp on the welding table is replaced along with the specification change of the shock absorber, and the purpose of adapting to the shock absorbers with different specifications through the self adjustment of the welding table is realized by respectively positioning a oil storage cylinder and a hanging ring and adjusting the positioning height of the hanging ring according to the outer diameter of the oil storage cylinder so as to align the oil storage cylinder with the hanging ring, thereby avoiding the replacement of the positioning clamp. In order to achieve the above purpose, the present invention provides the following technical solutions: The shock absorber welding table consists of a rotary positioning module of a positioning hanging ring and a movable positioning module of a positioning oil storage cylinder, and comprises a frame and a lifting plate, wherein the lifting plate is connected to the frame in a sliding manner, the rotary positioning module comprises a fixed plate, a movable plate and a clamping plate, the fixed plate is arranged on the lifting plate, the movable plate is hinged to the lifting plate, the two movable plates are respectively arranged on the left side and the right side of the fixed plate, the movable positioning module comprises a supporting plate and guide plates, the supporting plate is arranged on the frame, the front and rear central surfaces of the supporting plate are overlapped with the front and rear central surfaces of the fixed plate, the guide plates are connected on the frame in a sliding manner, and the two guide plates are respectively positioned on the front side and the rear side of the supporting plate; The hanging rings and the oil storage cylinders are respectively arranged on the upper sides of the movable plates and the guide plates, the two movable plates are relatively opened to enable the hanging rings to fall to the fixed plates, the hanging rings falling to the fixed plates are clamped by two clamping plates which move in a similar manner, the two guide plates move far away from each other to enable the oil storage cylinders to fall to the supporting plates, and the lifting plates are adjusted up and down to enable the center shafts of the hanging rings and the center shafts of the oil storage cylinders to be coplanar. Preferably, the rotation positioning module further comprises a first screw rod, a first motor, a sliding block, racks and gears, wherein the first screw rod is rotationally connected to the lifting plate, the first m
