Description

Technical Field

[0001] The utility model relates to the technical field of screw locking machines, in particular to a screw locking machine for oil pipe joints. Background Technique

[0002] Bicycles, motorcycles, and electric bicycles all rely on the use of brake cables. The maintenance of brake cables requires the use of maintenance oil, and the use of maintenance oil needs to be transported through oil pipes. The oil pipe joint is an important component for connecting oil pipes. Its function is to connect, seal, and support oil pipes in the oil pipe system to ensure the normal operation of the entire system. Oil pipe joints are usually used in pipeline systems in industries such as petroleum, natural gas, and chemical engineering, and are subjected to working conditions such as high pressure, high temperature, and corrosion. Oil pipe joints are usually made of high-strength and corrosion-resistant materials such as carbon steel, alloy steel, and stainless steel. With the progress of technology, new high-performance materials such as titanium alloys and nickel-based alloys are also widely used in oil pipe joints under some special working conditions to improve their corrosion resistance, wear resistance, and high-temperature resistance. A joint screw is provided on the oil pipe joint, and the screw needs to be locked on the oil pipe joint during use.

[0003] At present, the locking of the oil pipe joint screw is generally carried out by manually locking the screw at the oil pipe joint. Manual operation is very time-consuming and laborious, with high costs and very low efficiency. Moreover, it is very easy to have the situation that the screw cannot be tightened during manual operation, resulting in oil leakage during use. For this reason, we propose a screw locking machine for oil pipe joints. Content of the Utility Model

The top of the columns 4 is fixedly installed with a hydraulic cylinder 6, and the end of the piston rod of the hydraulic cylinder 6 is fixedly connected to the lifting slider 7.

[0019] It should be noted that through the setting of the hydraulic cylinder 6, the lifting and moving of the lifting slider 7 on the slide rail 5 can be controlled.

[0020] The surface of the lifting slider 7 is provided with a tightening mechanism 25. A mounting seat 13 is fixedly installed directly below the tightening mechanism 25 on the top of the frame 1.

[0021] It should be noted that when the present utility model is used, the position of the fixing seat 24 on the mounting seat 13 is adjusted as needed to make the oil pipe joint in the mounting groove on the fixing seat 24 correspond to the position of the clamping groove 10 on the gearbox 9. During adjustment, by rotating the first knob 17, the first screw rod 16 rotates. Through the threaded connection between the first screw rod 16 and the sliding block thereon, the fixing seat 24 is moved along the Y-axis direction. By rotating the second knob 22, the second screw rod 20 rotates. Through the threaded connection between the second screw rod 20 and the sliding seat thereon, the fixing seat 24 is moved in the X-axis direction, so that the fixed oil pipe joint corresponds to the position of the screw fixed on the clamping cylinder 11. The oil pipe joint to be connected with the screw is fixedly installed in the mounting groove on the fixing seat 24. Then, the hydraulic cylinder 6 is controlled to work through the control system set by the device, and the height position of the tightening mechanism 25 on the lifting slider 7 is adjusted. The joint screw to be connected is fixed on the clamping port of the clamping cylinder 11. Then, the hydraulic cylinder 6 works to control the height of the tightening mechanism 25 to drop, so that the joint screw is correspondingly connected with the oil pipe joint in the mounting groove on the fixing seat 24. After the correspondence is completed, the clamping cylinder 11 is loosened. Then, the driving motor 8 is controlled to work, so that the gear set 12 rotates, thereby controlling the tightening of the screw on the oil pipe joint and realizing the tightening of the oil pipe joint screw.

[0022] The tightening mechanism 25 includes a driving motor 8, a gearbox 9, a clamping groove 10, a clamping cylinder 11 and a gear set 12. The surface of the lifting slider 7 is fixedly connected with a gearbox 9, and a gear set 12 is arranged inside the gearbox 9. At one end of the lifting slider 7 on the top of the gearbox 9, a driving motor 8 is fixedly installed, and the end of the output shaft of the driving motor 8 extends into the gearbox 9 and is connected with the gear set 12. The end of the central shaft of the gear set 12 passes through the gearbox 9 and is fixedly connected with a tightening head. A clamping groove 10 is opened at the end of the gearbox 9, and the tightening head at the bottom of the gearbox 9 is arranged inside the clamping groove 10 in a matching manner.

[0023] It should be noted that the control system set by the device controls the driving motor 8 to work. Through the gear set 12 inside the gearbox 9, the tightening head rotates. When the joint screw of the tightening head rotates and is connected at the oil pipe joint, the joint screw can be quickly locked on the oil pipe joint, improving the locking efficiency and quality, and also saving the labor operation cost.

[0024] The mounting seat 13 includes a base 14, a fixing plate 15, a first screw rod 16, a first knob 17, a support plate 18, a mounting plate 19, a second screw rod 20, a placing plate 21, a second knob 22, an adjusting seat 23 and a fixing seat 24. The top of the frame 1 is fixedly connected with the base 14, and the top of the base 14 is symmetrically and fixedly connected with the fixing plates 15. A first screw rod 16 is rotatably connected between the two fixing plates 15. The end of the first screw rod 16 passes through the fixing plate 15 and is fixedly connected with the first knob 17. A sliding block is threadedly connected to the outer side of the first screw rod 16, and the top of the sliding block is fixedly connected with the support plate 18.

[0025] It should be noted that by rotating the first knob 17, the first screw rod 16 rotates. Through the threaded connection between the first screw rod 16 and the sliding block thereon, the fixing seat 24 is moved along the Y-axis direction.

[0026] The top of the support plate 18 is symmetrically and fixedly connected with the mounting plates 19. A second screw rod 20 is rotatably connected between the two mounting plates 19. The second screw rod 20 is perpendicular to the first screw rod 16.
