DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0022] Embodiment. A semi-automatic assembly device for a plunger ring, such as Figure 1 As shown, it includes a base plate 6, on which two feeding mechanisms are placed. The feeding mechanism includes a vibration plate loader 1, in which a large number of plunger rings 29 are placed. A slideway 2 is provided at the output end of the vibration plate loader 1. The width of the slide groove on the slideway 2 matches the diameter of the plunger ring 29, and a straight vibrator 7 fixed to the base plate 6 is provided at the bottom of the slideway 2.

[0023] A push plate assembly 3 is provided at the output end of the slideway 2 , a press-fitting base assembly 4 is provided on the feeding side of the push plate assembly 3 , a press-fitting cylinder 5 is provided above the press-fitting base assembly 4 , and the press-fitting cylinder 5 is connected to a bottom plate 6 .

[0024] The press-fit base assembly 4 includes a press-fit plate 8 located at one side of the discharge end of the slideway 2. The press-fit plates 8 in the two press-fit base assemblies 4 are connected to form an integral structure. Figure 2 As shown, the press-fitting plate 8 is connected to the base plate 6, and a mounting hole is provided on the press-fitting plate 8, and a press-fitting block 9 is provided in the mounting hole. A blind hole 10 is provided on the top of the press-fitting block 9, and a positioning ring 11 is provided in the blind hole 10 (the positioning ring 11 is composed of left and right side rings, and the inner hole size of the positioning ring is variable. For detailed structure, see the assembly device of application number 202311477719.X), an annular groove 12 is provided on the top of the positioning ring 11, and the inner diameter of the annular groove 12 matches the outer diameter of the plunger ring 29, and a conical surface 15 is provided on the outer side wall of the lower end of the guide body 13, and a cylindrical guide body 13 is provided on the upper side of the positioning ring 11, and the diameter of the cylindrical part of the guide body 13 matches the inner diameter of the positioning ring 11, and a groove 14 is provided on the upper end of the guide body 13, and the diameter of the groove 14 matches the diameter of the plunger body 30, and the depths of the grooves 14 on the two guide bodies 13 are different.

[0025] In order to limit the positioning ring 11 to remain unchanged in the height direction, arc grooves in the horizontal direction may be provided on the outer sides of the left and right side rings of the positioning ring 11 , and steel balls elastically connected to the press-fitting block 9 are provided in the arc grooves.

[0026] A spring cavity 16 is provided in the press-fitting block 9, a compression spring 17 is provided in the spring cavity 16, an ejector pin 18 is provided at the upper end of the compression spring 17, and the upper end of the ejector pin 18 is a conical surface. A tapered hole 31 is provided on the lower end surface of the guide body 13, and the upper end of the ejector pin 18 extends into the blind hole 10 and elastically abuts against the tapered hole 31.

[0027] The press-fitting base assembly 4 also includes an air claw 19, the grabbing end of the air claw 19 is located above the press-fitting block 9, and a lifting cylinder 32 connected to the air claw 19 is provided on the press-fitting plate 8. Preferably, a guide mechanism is also provided between the press-fitting plate 8 and the air claw 19 to prevent the air claw 19 from rotating.

[0028] like Figure 3 As shown, the push plate assembly 3 includes a pushing cylinder 20 connected to the press plate 8, and a push plate 21 is provided at the output end of the pushing cylinder 20. The push plate 21 fits the press plate 8, and the pushing direction of the push plate 21 points to the press block 9 and is perpendicular to the slide 2. The push plate 21 forms a notch on one side of the slide 2.

[0029] like Figure 4 As shown, a limit block assembly 22 is provided between the push plate assembly 3 and the slideway 2. The limit block assembly 22 includes a height limit plate 23 located above the press plate 8. The height limit plate 23 is arranged horizontally. A fixed plate 24 and a movable plate 25 are respectively provided at both ends of the height limit plate 23. The fixed plate 24 and the movable plate 25 are both fitted with the press plate 8. A channel is formed between the fixed plate 24 and the movable plate 25. A moving block 26 passing through the height limit plate 23 is provided on the movable plate 25. The moving block 26 is connected to the height limit plate 23 by a bolt 27. When the bolt 27 rotates, the moving block 26 drives the movable plate 25 to move. An inclined surface 28 is provided on the side of the fixed plate 24 facing the movable plate 25 and the side of the movable plate 25 facing the fixed plate 24.

[0030] Instructions for use: Take one of the feeding mechanisms as an example: the plunger ring 29 in the vibrating plate loader 1 enters the slideway 2 and continues to move forward under the action of the straight vibrator 7.

[0031] When the plunger ring 29 moves to the limit block assembly 22, the height limiting plate 23 ensures that only one plunger ring 29 can pass through in the height direction. Figure 5 As shown, the shape of the plunger ring 29 is large at one end and small at the other end. By adjusting the distance between the fixed plate 24 and the movable plate 25, it is ensured that only one plunger ring 29 can pass through in the horizontal direction, and the inclined surface 28 is used to only allow the plunger ring 29 with the large end facing upward to pass. If it is found that the plunger ring 29 cannot pass, the plunger ring 29 can be flipped 180°.

[0032] When the plunger ring 29 moves to the push plate assembly 3 , the plunger ring 29 enters into the notch of the push plate 21 , and the push cylinder 20 pushes the push plate 21 to push the plunger ring 29 into the annular groove 12 of the positioning ring 11 .

[0033] The worker takes a plunger body 30 and puts the plunger body 30 into the groove 14 at the upper end of the guide body 13; the lifting cylinder 32 contracts, and the air claw 19 drives the guide body 13 to descend in height, so that the lower end of the guide body 13 is inserted into the positioning ring 11; then the air claw 19 is released; the pressing cylinder 5 is used to press the plunger body 30 downward, and the guide body 13 is out of the clamping range of the air claw 19, and the plunger ring 29 is relatively raised along the outer wall of the guide body 13. When the upper end surface of the guide body 13 is at the same height as the bottom surface of the annular groove 12, the plunger ring 29 enters the installation groove on the upper side of the plunger body 30; then the pressing cylinder 5 contracts and resets, and at the same time the ejector pin 18 pushes the guide body 13 upward, so that the guide body 13 re-enters the clamping range of the air claw 19; then the air claw 19 clamps the guide body 13; then the lifting cylinder 32 extends to return the guide body 13 to its original height, and the worker can take away the plunger body 30 with a plunger ring 29 installed. Repeat the above-mentioned steps to assemble another plunger ring 29 into the mounting groove on the lower side of the plunger body 30 .

[0034] As a further optimization, a controller can be provided for each feeding mechanism, and a control button can be connected to the controller. All pneumatic components in the feeding mechanism are connected to the controller through corresponding solenoid valves. When the control button is pressed, the push plate assembly 3 and the press-fit base assembly 4 automatically perform an action process according to the above steps. In the field of automation equipment, the above control method is a conventional means, so it will not be described in more detail.
