Fig. 1 is a perspective view of a plug attaching and detaching device according to the present invention.

Detailed Description

As shown in fig. 1, the plug dismounting device includes a frame 1 and a screwing component. The frame 1 is a frame structure, and an oil collecting tank 11 is arranged in the middle of the frame. Two groups of screwing parts are arranged at the top of the frame 1. The working areas of the two groups of screwing parts face opposite directions, and two working positions are formed on two sides of the frame 1.

The screwing component comprises a bottom plate 2, an electric screwing component 3, a translation mechanism, a limiting seat 4, a switch unit 5 and a vibration suppression component 10. The base plate 2 is a flat metal plate, and the base plate 2 is used for supporting. The translation mechanism comprises a carrier plate 6 and a linear cylinder 7. Carry thing board 6 and pass through the guide rail and install on bottom plate 2, this guide rail includes linear slide rail and guide pin bushing, and linear slide rail fixed mounting is on bottom plate 2, and the guide pin bushing is installed in carrying thing board 6 below, carries thing board 6 and passes through linear slide rail embedding guide pin bushing and bottom plate 2 swing joint, so carry thing board 6 alright with be the linear motion on the horizontal direction on bottom plate 2. The cylinder body of the linear cylinder 7 is fixed on the bottom plate 2, the piston rod of the linear cylinder 7 is fixed on the object carrying plate 6, and the object carrying plate 6 can be driven to do horizontal linear reciprocating motion after the piston rod of the linear cylinder 7 moves in a telescopic mode. When in use, the linear air cylinder 7 is communicated with the air supply pipeline, and the air supply control of the linear air cylinder 7 can be implemented by a foot switch arranged on the air supply pipeline. The electric screw unit 3 may adopt a technical means described in chinese patent publication No. CN211361283U, published on 28.8.2020, entitled nut runner and nut runner mechanism. Electronic subassembly 3 fixed mounting that revolves is equipped with sleeve 8 on the electronic subassembly 3 that revolves, sleeve 8 is last to be equipped with the blind hole that corresponds to the end cap, and the orientation of blind hole is on a parallel with the horizontal direction. The vibration suppressing member is a rectangular parallelepiped and is fixedly attached to the bottom plate 2, and a through hole is provided at an upper end portion of the vibration suppressing member, and the sleeve 8 penetrates through the through hole. The stop block 4 is fixed to the base plate 2 with the sleeve 8 facing upwards, i.e. with the sleeve 8 facing the stop block 4, the sleeve 8 facing parallel to the horizontal, which allows the vibration suppressing member 10 to be located between the stop block 4 and the electric screw assembly 3. The limiting seat 4 is provided with a U-shaped groove 9, and the width of the groove 9 is the same as that of a nut on the high-pressure oil pipe. Spacing seat 4 is located and carries thing board 6 on bottom plate 2 translational motion's direction, carries thing board 6 to drive and revolves electronic subassembly 3 of twisting and be the translational motion back, and sleeve 8 can be close to or keep away from spacing seat 4. The switch unit 5 is used for sensing that a nut of the high-pressure oil pipe is embedded into the groove 9 of the limiting seat 4, and is essentially a proximity switch, and a photoelectric switch is taken as an example in the embodiment. The switch unit 5 is installed at one side of the stopper base 4. The switching unit 5 is connected to the electric screwing assembly 3, both of which are connected in series on the same power supply line, so that the electric screwing assembly 3 operates according to a signal given by the switching unit 5.

The two groups of screwing components are arranged on the top of the frame 1 in an opposite orientation mode, so that the sleeve 8 in one group of screwing components on the frame 1 faces opposite to the sleeve 8 in the other group of screwing components; and the two sets of screwing elements work differently, which results from the fact that the two sleeves 8, on the basis of the aforementioned position, turn the same in the sleeve 8 in one of the sets of screwing elements as in the sleeve 8 in the other set of screwing elements. In this way, the rotation direction of one of the sleeves 8 is used for screwing the plug, and the rotation direction of the other sleeve 8 is used for screwing the plug.

In the initial state, the linear air cylinder 7 on the screwing component is in a contraction state, and the sleeve 8 is far away from the limiting seat 4. When in use, the plug is firstly arranged in the blind hole of the sleeve 8, and the sleeve 8 is provided with the plug; then, the high-pressure oil pipe is arranged on the limiting seat 4, a nut carried by the high-pressure oil pipe is arranged at one end of the high-pressure oil pipe, and the nut is embedded in a groove 9 of the limiting seat 4; and then, starting the linear cylinder 7, pushing the sleeve 8 in a non-rotating state to the position of the nut until the plug and the nut are contacted with each other, then, starting the electric screwing component 3 according to the state that the high-pressure oil pipe triggers the switch unit 5, if the switch unit 5 is not started, the electric screwing component 3 cannot be started, otherwise, the electric screwing component is started, and the sleeve rotates to drive the plug to rotate and screw the plug into the nut. After screwing up, the sleeve pipe does not rotate, and the linear cylinder 7 drives the electric screwing component 3 to do the motion of keeping away from the limiting seat 4 until the initial state is recovered. And finishing the assembling operation of the plug.

When the plug is required to be unscrewed and detached, the nut is embedded into the groove 9 of the limiting seat 4, and the sleeve 8 moves towards the position of the limiting seat 4 until the plug is embedded into the blind hole of the sleeve 8. Under normal conditions, the electric screwing component 3 is started according to the fact that the high-pressure oil pipe triggers the switch unit 5, if the switch unit 5 is not started, the electric screwing component 3 cannot be started, and the sleeve 8 rotates in a direction opposite to the rotation direction when the plug is screwed down, so that the plug is screwed down from the nut. The plug is embedded in the sleeve 8, and when the linear cylinder 7 drives the electric screwing component 3 to move away from the limiting seat 4, the plug is completely separated from the nut, so that the multi-figure disassembling operation is completed.

The assembly operation can be performed by one set of screw elements and the disassembly operation by the other set of screw elements. The station for assembling operation is positioned on one side of the frame 1, and the station for disassembling operation is positioned on the other side of the frame 1, so that the assembling operation and the disassembling operation can be simultaneously carried out; the two stations are separated to meet the requirements of production line production, so that the arrangement of related equipment is convenient, and production raw materials can conveniently enter and exit the production line. The oil collecting groove 11 is positioned below the two groups of screwing parts, and high-pressure oil dropping from the high-pressure oil pipe after the plug is detached can be blocked by the oil collecting groove 11 and collected together. The sleeves 8 of the two screwing parts are rotated in the same direction, so that the function of improving the operation safety degree is achieved, and in an emergency that the plug is abnormally separated from the sleeve 8, the plug which is abnormally separated can be driven to move towards the direction far away from an operator by utilizing the rotation direction of the sleeve 8, so that the operator can be protected from being damaged.
