[0002] As a mechanical connecting piece, a plug is widely used in various fields and products. The plug can tightly connect two or more objects together and fix their positions. During the process of tightening a fixed plug, it is usually necessary to press the plug into the product with a certain pressure and maintain this pressure state. To achieve this goal, the method of using equipment to assist manual pressing is often adopted. In this operation, one person is responsible for pressing, while another person is responsible for the tightening operation;

[0003] In the press-fitting and tightening process of the plug, manual operation is cumbersome, and since the two sides of the plug are provided with side ears for easy manual tightening, there is no corresponding structure in the prior art that can achieve the press-fitting and tightening of the plug.

[0004] To solve the above problems, a press-fitting and tightening device is proposed in this application. Content of the Utility Model

[0005] Based on the technical problems existing in the background art, the utility model proposes a press-fitting and tightening device.

[0006] A press-fitting and tightening device proposed by the utility model includes a mounting frame;

[0007] A motor and a cylinder for driving the motor to move up and down are mounted on the mounting frame;

[0008] The output end of the motor is connected with a press-fitting cylinder. A press-fitting chamber is opened in the press-fitting cylinder. Fixed blocks are mounted on both sides of the press-fitting cylinder. A plurality of assembly chambers are opened in each of the two fixed blocks. Rod-shaped elastic members are mounted in the plurality of assembly chambers, and the ends of the rod-shaped elastic members extend into the press-fitting chamber;

[0009] A water pressure member communicated with the plurality of rod-shaped elastic members is mounted on the fixed block;

[0010] Pulling members are arranged on the sides of the two fixed blocks away from each other. The two pulling members are respectively connected with the plurality of rod-shaped elastic members in the two fixed blocks.

[0011] Preferably, the rod-shaped elastic member includes a fixed cylinder. The plurality of fixed cylinders are respectively mounted in the plurality of assembly chambers in the two fixed blocks. An elastic part is mounted in the fixed cylinder, and the end of the elastic part slides through one end of the fixed cylinder and the outer periphery of the press-fitting cylinder and extends into the press-fitting chamber.

[0012] Preferably, the elastic part includes a first piston which is slidably arranged in a fixed cylinder. A pressure rod is installed at the end of the first piston, and the end of the pressure rod away from the first piston slidably passes through one end of the fixed cylinder and the outer periphery of the pressing cylinder and extends into the pressing chamber. A first spring sleeved on the pressure rod is arranged inside the fixed cylinder, and two ends of the first spring are respectively connected with the first piston and the inner wall of one end of the fixed cylinder.

[0013] Preferably, the water pressure part includes a water pressure cylinder which is installed on a fixed block. An elastic top piece is installed inside the water pressure cylinder. A shunt pipe communicated with the inside of the water pressure cylinder is connected to the bottom end of the water pressure cylinder. A plurality of water guide pipes are communicated with the shunt pipe, and the ends of the plurality of water guide pipes away from the shunt pipe are respectively communicated with the inside of a plurality of fixed cylinders.

A plurality of pull rods are installed on the side of the two hand-pulling plates close to each other. The plurality of pull rods respectively slidably pass through the other ends of the plurality of fixed cylinders and are connected with the plurality of first pistons.

[0016] The above technical solution of the present utility model has the following beneficial technical effects:

[0017] By arranging the rod-shaped elastic part and the water pressure part, the hand-pulling parts on both sides of the pressing chamber can respectively apply a pulling force to the plurality of rod-shaped elastic parts in the two fixed blocks, so that the rod-shaped elastic parts in the two fixed blocks move away from each other. Then, the plug is placed into the pressing chamber opened in the pressing cylinder. Subsequently, the pulling force applied to the hand-pulling part is withdrawn. Under the elastic action of the rod-shaped elastic part, it can return to its original position and abut against the outer periphery of the plug. Since the rod-shaped elastic parts are densely arranged, the plug can be self-adaptively clamped, and under the water pressure action of the water pressure part, the clamping force on the plug can be increased. Then, the cylinder can be used to drive the motor to move towards the product, so that the plug in the pressing cylinder is inserted into the product. Then, the motor can be used to drive the pressing cylinder to rotate to screw the plug tightly. Through the design of the rod-shaped elastic part and the water pressure part, the structure can adapt to plugs with special-shaped structures, which is convenient for pressing and screwing the plug tightly into the product, and is convenient to use.

An elastic part 72 is installed inside the fixing cylinder 71, and the end of the elastic part 72 slides through one end of the fixing cylinder 71 and the outer periphery of the pressing cylinder 4 and extends into the pressing chamber 5. The elastic part 72 includes a first piston 721. The first piston 721 is slidably arranged inside the fixing cylinder 71. A pressing rod 722 is installed at the end of the first piston 721, and the end of the pressing rod 722 away from the first piston 721 slides through one end of the fixing cylinder 71 and the outer periphery of the pressing cylinder 4 and extends into the pressing chamber 5. A first spring 723 is sleeved on the pressing rod 722 and is located inside the fixing cylinder 71. The two ends of the first spring 723 are respectively connected to the first piston 721 and the inner wall of one end of the fixing cylinder 71.

[0027] In this embodiment, a water pressure member 8 communicating with the plurality of rod-shaped elastic members 7 is installed on the fixing block 6. The water pressure member 8 includes a water pressure cylinder 81. The water pressure cylinder 81 is installed on the fixing block 6. An elastic top member 82 is installed inside the water pressure cylinder 81. The bottom end of the water pressure cylinder 81 is connected to a shunt pipe 83 communicating with its interior. A plurality of water guide pipes 84 are communicated with the shunt pipe 83. The ends of the plurality of water guide pipes 84 away from the shunt pipe 83 are respectively communicated with the interiors of the plurality of fixing cylinders 71. Liquid water is provided inside both the fixing cylinder 71 and the water pressure cylinder 81. The elastic top member 82 includes a second piston 821. The second piston 821 is slidably arranged inside the water pressure cylinder 81 and abuts against the liquid water. A movable rod 822 is installed on the second piston 821, and the top end of the movable rod 822 slides through the top end of the water pressure cylinder 81. A second spring 823 is sleeved on the movable rod 822 and is located inside the water pressure cylinder 81. The two ends of the second spring 823 are respectively connected to the second piston 821 and the top end inside the water pressure cylinder 81.

[0028] In this embodiment, pulling members 9 are provided on the sides of the two fixing blocks 6 away from each other.
