DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0016] Embodiment, by Figures 1 to 12The present invention includes an assembly base 1; a T-shaped angle valve, consisting of a horizontal pipe and a vertical pipe, is provided on the top of the assembly base 1; the vertical pipe is perpendicular to the top of the assembly base 1; the horizontal pipe is parallel to the top of the assembly base 1; a torque reversing assembly is provided on the assembly base 1 for actively controlling the rotation direction of the T-shaped angle valve; the torque reversing assembly includes a rotating annular groove 2, disposed on the top of the assembly base 1; a rotating base 3 is fitted into the rotating annular groove 2, and the two are rotatably engaged; a locking anti-rotation device is provided on the rotating base 3 for use during the tightening operation of the accessory and the T-shaped angle valve. To prevent the T-type angle valve from shifting or rotating; T-type pipe 6, installed on the top of the assembly base 1; two T-type pipes 6 are located on both sides of the U-shaped base 4 and are symmetrically arranged with the guide screw 5 as the axis of symmetry; limited resistance energy absorption unit is installed on the T-type pipe 6 to reduce the impact force on the T-type angle valve during assembly; auxiliary cavity 9 is set inside the assembly base 1; drive motor 10 is installed inside the auxiliary cavity 9; the output end of drive motor 10 passes through the top of the assembly base 1 and is connected to the rotating base 3; drive gear ring 11 is connected to the top of the assembly base 1; When assembling a T-type angle valve, the locking anti-rotation device is used to fix the T-type angle valve to the top of the assembly base 1. When tightening the fittings onto the valve body, i.e., the horizontal or vertical pipe, according to mechanical principles, the tightening force on the fittings will generate a reverse torque on the valve body. At this time, by starting the drive motor 10, its output end drives the rotating base 3 to rotate, limiting its rotation within the rotating annular groove 2. The locking anti-rotation device is set on the rotating base 3, which can also drive the T-type angle valve to rotate, used to adjust its direction. When the T-type angle valve is subjected to a tightening force in one direction, the above operation causes the T-type angle valve to rotate in the opposite direction, which actively counteracts the above force. The torque generated by the T-type angle valve is actively counteracted to balance the torque, preventing the T-type angle valve from shifting or rotating under this torque and thus damaging the preset assembly reference. This further avoids affecting the relative positional accuracy of the T-type angle valve components, such as the coaxiality and installation angle of the accessories (valve core, valve stem) and valve body. At the same time, it can also actively drive the T-type angle valve to rotate, which is used to control its angle and orientation during assembly. It actively matches the installation angle and position of the accessories, avoiding mismatches that affect the assembly of the angle valve. This reduces the limitations of the equipment when assembling angle valves and improves the assembly effect of the equipment.

at the same time, the rubber arc pad 20 on the first lock block 19 contacts the side wall of the vertical pipe, which is used to increase the friction between the vertical pipe and the first lock block 19, avoiding the dislocation caused by the sliding of the T-shaped corner valve during assembly, which affects the assembly effect and accuracy, so that the assembly effect of the equipment on the T-shaped corner valve is improved; at the same time, the continuous rotation of the guide screw 5 drives the guide blocks 12 to continue to move, so that the guide plates 15 on them are limited to move at the locking cylinder 16, so that the locking spring 18 is in a buffer state, which is used to ensure and strengthen the contact strength of the first lock block 19 and the vertical pipe, avoiding the dislocation of the vertical pipe caused by non-human factors when it is fixed, which affects the assembly effect of the corner valve; after the guide plate 15 moves a certain distance, the signal contact 40 on the opposite side of the guide plate 15 and the first lock block 19 comes into contact, indicating that the two first lock blocks 19 have fixed and clamped the vertical pipe, avoiding the insufficient clamping of the vertical pipe or the insufficient strength affecting the assembly effect of the equipment on the vertical pipe, that is, the T-shaped corner valve; at this time, the horizontal pipe on the T-shaped corner valve is parallel to the top of the assembly base 1, and the contact of the two signal contacts 40 also sends a signal to the controller, which sends a start signal to the electric extender 22, so that the second lock block 23 on the output end moves close to the side wall of the horizontal pipe and contacts, which is used to further clamp the horizontal pipe, that is, to fix the horizontal pipe on the basis of clamping the vertical pipe, which is used to fix and limit the T-shaped corner valve in multiple directions, avoiding the torsion caused by tightening the accessory on the T-shaped corner valve, which causes it to deviate or rotate; so that the valve body can be effectively fixed, avoiding the reverse torsion of the tightening force of the accessory on the valve body, that is, the vertical pipe, causing it to deviate or rotate, so that the preset assembly reference of the T-shaped corner valve during assembly cannot be destroyed, thereby affecting the relative position accuracy of the components of the corner valve, such as the coaxiality of the accessory (valve core, valve stem) and the valve body, the installation angle, etc.; finally, it avoids the corner valve from not being able to be used normally after assembly, or the sealing performance is significantly reduced, thereby further reducing the limitations of the equipment in assembling the corner valve, while the assembly accuracy of the corner valve is also improved.

When the locking and rotation stopping device clamps the angle valve, the two guide blocks 12 are in a relative moving state, the two guide columns 14 on the two guide blocks 12 are respectively limited to move in the two ends of the T-shaped pipe 6, so that the gas in the T-shaped pipe 6 is extruded into the U-shaped pipe 7 and acts on the end of the U-shaped pipe 7 towards the T-shaped angle valve, so that the gas in the end acts on the resistance sliding column 8, the resistance sliding column 8 is slidingly connected at the end of the U-shaped pipe 7 towards the T-shaped angle valve, the resistance spring 26 is in a buffering state, so as to drive the resistance arc plate 25 on the resistance sliding column 8 to move close to the vertical pipe, and the two T-shaped pipes 6 are located on both sides of the U-shaped base 4 and are symmetrically arranged with the guide screw 5 as the symmetric axis, so that the two resistance arc plates 25 on both sides of the vertical pipe move relatively and gradually close to the vertical pipe, so that the resistance arc plate 25 drives the resistance screw plate 30 to move close to the side wall of the vertical pipe under the action of the resistance square cylinder 28 and the resistance square column 29, and contacts the threads at the bottom of the vertical pipe, so as to lock the vertical pipe at this position. If the T-shaped angle valve, that is, the vertical pipe, moves up and down due to non-human factors, the threads at the bottom of the vertical pipe cannot move due to the contact with the threads on the resistance screw plate 30, so as to limit the vertical pipe at the current height position and cannot move up and down, avoiding the phenomenon that the valve body moves or dislocates due to ineffective fixation, thereby improving the assembly precision of the device for the angle valve and further reducing the limitation of the device when assembling the angle valve. At the same time, the buffering performance brought by the auxiliary spring 31 reduces the impact force suffered by the T-shaped angle valve during assembly, improves the stability of the angle valve during assembly, and improves the assembly precision of the device for the angle valve, further improving the use effect of the device.
