Technical Field

[0001] The utility model relates to the technical field of automatic quick-draw pipe joints, in particular to an automatic quick-draw hydraulic oil pipe joint device. Background Art

[0002] With the rapid development of the automobile industry, competition in the auto parts market is becoming increasingly fierce. Low-cost, high-quality, fast and automatic processing has undoubtedly become a sharp weapon to enhance market competitiveness.

[0003] After the automobile steering gear assembly is assembled on the production line, it needs to be hydraulically tested on the test bench to prevent abnormal situations such as steering gear oil leakage, steering jamming, sinking, etc. When connecting the hydraulic pipeline to the oil inlet and outlet of the steering gear, an imported special quick pipe joint is used. The structure of this pipe joint is a spring lock type. When the steering gear is hydraulically tested, it needs to be manually connected. After the test, the lock needs to be manually released and pulled out. This process has high labor intensity and low efficiency, and is not suitable for large-scale operations. In view of the above problems, an automatic quick-pull hydraulic oil pipe joint device is proposed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide an automatic quick-pull hydraulic oil pipe joint device. The device is simple and practical. After the hydraulic test of the steering gear is completed, the lock can be automatically released to pull out the hydraulic oil pipe joint, thereby improving work efficiency, reducing the labor intensity of employees' manual operations, reducing manufacturing costs, and improving work efficiency. It can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic quick-pull hydraulic oil pipe joint device, including a support sleeve and a clamp, a vertical plate is arranged on the outer surface of the support sleeve, a cylinder is fixed on the vertical plate, a screw is arranged at the opening of the clamp, the upper part of the opening of the clamp is arranged at an inner bending structure, positioning holes are formed between the inner bending structures, a connecting rod is arranged at the telescopic end of the cylinder, the connecting rod passes through the positioning hole, and a locking nut is arranged at the end of the connecting rod, the clamp is tightly clamped on the pipe joint, and the pipe joint is inserted into the support sleeve.

[0006] Furthermore, the outer shape of the support sleeve is set to be a hexagonal shape, the inner hole of the support sleeve is set to be a hexagonal shape, and the size of the inner hole of the support sleeve is larger than the outer size of the pipe joint.

[0007] Furthermore, the pipe joint has a front groove and a rear groove, and the clamp is arranged at the front groove.

[0008] Furthermore, a second screw is provided on the outer surface of the support sleeve, and the second screw passes through the support sleeve into the rear groove.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The device is simple and practical, easy to repair and replace, and has a low manufacturing cost. After the hydraulic test of the steering gear is completed, the lock can be automatically released to pull out the hydraulic oil pipe joint, thereby improving work efficiency. The power of the cylinder is used instead of manually releasing the spring lock of the hydraulic pipe joint, thereby reducing the labor intensity of employees' manual operations and improving work efficiency.
