Description

Technical Field

[0001] This application relates to the technical field of cylinder welding tooling, for example, a hydraulic cylinder barrel hinge shaft welding tooling is involved. Background Art

[0002] The cylinder barrel is the main component of a hydraulic cylinder. Connecting hinge shafts are welded on both sides of the outer circle of the cylinder barrel of the balance cylinder. The hinge shafts mainly play a role in connecting and fixing the cylinder, bear a large lateral force, and require a high degree of coaxiality.

[0003] At present, the cylinder barrel hinge shaft welding process is to align the semi-finished hinge shaft after finding the correct position with an angle gauge. During welding, one hinge shaft is used as a reference for positioning. The manual angle gauge has a large positioning tolerance range and is not easy to operate. It is not only difficult to ensure the welding quality, but also has low efficiency, and at the same time, the labor intensity is high. Especially during mass production, welding is even more difficult. Utility Model Content

The core shaft seat is arranged at the center position inside the base. Y-shaped blocks are provided on both sides of the core shaft seat. The core shaft seat is of a cylindrical structure. The bottom end of the cylinder barrel is inserted into the core shaft seat for butt-joint with the cylinder barrel. The hinge shafts for butt-joint with the cylinder barrel are supported on both sides of the cylinder barrel by the Y-shaped blocks. The core shaft seat is a flexibly assembled component and can be adapted by replacing different specifications according to different cylinder barrel styles. The side plates are respectively penetrated by clamping screws in a threaded manner. The two groups of clamping screws correspond to the Y-shaped blocks on both sides of the core shaft seat. The end of the clamping screw can press against the end of the hinge shaft. By tightening the clamping screw, it can be ensured that the corresponding hinge shaft is fixed at the side wall position of the cylinder barrel. Then, an automatic welding can be carried out by a welding robot, and thus the overall welding operation can be completed. The bottom of the Y-shaped block is movably connected to the bottom side inside the base, and its position can be adjusted to facilitate the adjustment of the erection position of the hinge shaft, further ensuring the stability of the fixation of the hinge shaft, and then ensuring the quality of the cylinder barrel welded with the hinge shaft. Fixing the hinge shaft by the clamping screw can reduce the labor intensity of workers, and can fix the hinge shafts on both sides simultaneously, facilitating one-time welding and improving work efficiency.

[0008] Furthermore, a T-shaped slider is provided at the bottom of the Y-shaped block, and T-shaped grooves are respectively formed at the bottom side inside the base corresponding to the T-shaped sliders.

[0009] Furthermore, a buffer plate is provided at one end of the clamping screw close to the hinge shaft. The buffer plate is made of soft material, which can effectively prevent the clamping screw from damaging the end of the hinge shaft. Drive blocks are fixed to the other ends of the clamping screws, and adjustment rockers are inserted into the drive blocks. The operator can rotate and adjust the clamping screws through the adjustment rockers.

[0010] Furthermore, a threaded sleeve is fixedly provided at the bottom of the mandrel seat. The threaded sleeve is threadedly sleeved with an adjustment screw. The top end of the adjustment screw passes through the base and is fixedly connected to the bottom end of the mandrel seat. By rotating the adjustment screw, the height of the mandrel seat can be adjusted, and then the position of the hinge shaft welded to the cylinder barrel can be conveniently adjusted, increasing the practicability.

[0011] Furthermore, a disc wheel is provided at the bottom end of the adjustment screw, and a crank is fixed to one side of the disc wheel, which is convenient for the operator to adjust the adjustment screw.

[0012] Furthermore, the base is of an overall square structure, and angle plates are fixedly provided at the four corner positions inside. The stability of the side plates is increased through the angle plates, and the service life is increased.

[0013] Furthermore, support screw barrels are respectively provided at the corner positions at the bottom of the base. Lifting screws are threadedly sleeved in the support screw barrels. The top ends of the lifting screws are fixedly connected to the bottom side of the base. The bottom ends of the support screw barrels are respectively rotatably connected to floor plates. The floor plates are used to contact the ground. The support of the base is realized through the cooperation of the floor plates, the support screw barrels and the lifting screws, and the positional relationship with the lifting screws can be adjusted by rotating the support screw barrels, and then the overall height of the base can be adjusted, further increasing the practicability.

[0014] A hydraulic cylinder barrel hinge shaft welding tooling provided by an embodiment of the present disclosure can achieve the following technical effects:

[0015] The end of the clamping screw in the present utility model can press against the end of the hinge shaft. By tightening the clamping screw, it can ensure that the corresponding hinge shaft is fixed at the side wall position of the cylinder barrel. Then, an automatic welding is carried out by a welding robot. The position can be adjusted through the Y-shaped block, which is convenient for adjusting the erection position of the hinge shaft, further ensuring the stability of the fixation of the hinge shaft, and thus ensuring the quality of the welding of the hinge shaft on the cylinder barrel. Fixing the hinge shaft by the clamping screw can reduce the labor intensity of workers, and can fix the hinge shafts on both sides simultaneously, facilitating one-time welding and improving work efficiency.
