The central axis of the push rod coincides with the central axis of the through hole, and the diameter of the push rod matches the diameter of the pin.

[0006] As a further improvement of this utility model, the front and rear widths of the guide groove and the hopper are matched with the length of the pin shaft, and the bottom of the hopper is inclined and cooperates with the guide seat.

[0007] As a further improvement of this utility model, an upper limit plate is provided above the guide groove.

[0008] As a further improvement of this utility model, after the box cover is positioned, the front-to-back distance between the pin in the guide groove and the pin positioning plate is less than the length of the pin.

[0009] As a further improvement of this utility model, the bottom of the hopper and the guide seat are fixed by a bracket.

[0010] As a further improvement of this utility model, the pressing mechanism includes a pressing block, the upper part of which is connected to a pressing cylinder, and the pressing cylinder is fixedly connected to the worktable through an L-shaped fixing frame.

[0020] like Figure 1As shown, the present invention discloses a pin assembly device for a box cover and a locking fastener, comprising a workbench 1, a positioning seat 2 fixed in the middle of the workbench 1 for placing the box cover 4, symmetrically arranged limiting blocks 3 on the positioning seat 2 to limit the front and rear positions of the box cover 4, and symmetrically arranged positioning blocks 5 on the left and right sides of the positioning seat 2 to limit the left and right positions of the box cover 4, with positioning grooves 51 machined on the upper part of the positioning blocks 5 for placing the locking plate 6, the end of the locking plate 6 facing the box cover 4 extending into the groove 42 of the pin positioning plate 41 at the edge of the box cover 4, and the positioning hole Ⅰ 61 on the locking plate 6 and the pin The positioning holes 43 on the shaft positioning plate 41 are aligned with the center. A pressing mechanism 7 is provided above the positioning block 5. The pressing mechanism 7 includes a pressing block 71. A pressing cylinder 72 is connected to the upper part of the pressing block 71. The pressing cylinder 72 is fixedly connected to the worktable 1 through an L-shaped fixing bracket 73. A feeding mechanism 9 is provided behind the positioning block 5 for conveying the pin shaft 8. A push rod 10 is provided behind the feeding mechanism 9. The center of the push rod 10 is aligned with the center of the positioning hole 43. The rear end of the push rod 10 is connected to a pushing cylinder 102. The pushing cylinder 102 is fixedly installed at the rear of the worktable 1 through a support base 101.

[0021] The feeding mechanism 9 includes a square hopper 91. An obliquely arranged guide seat 92 is installed on the opposite side of the hopper 91. The bottom of the hopper 91 and the guide seat 92 are fixed by a bracket 94. A guide groove 921 is machined on the upper part of the guide seat 92 and communicates with the lower part of the inner cavity of the hopper 91. The depth of the guide groove 921 matches the diameter of the pin 8. The front and rear widths of the guide groove 921 and the hopper 91 match the length of the pin 8. The bottom of the hopper 91 is obliquely arranged and cooperates with the guide seat 92. An upper limit plate 93 is provided above the guide groove 921. Through holes 922 are machined on the front and rear sides of the end of the guide groove 921 away from the hopper 91, which match the diameter of the pin 8. The central axis of the push rod 10 coincides with the central axis of the through hole 922. The diameter of the push rod 10 matches the diameter of the pin 8. After the box cover 4 is positioned, the front and rear distance between the pin 8 in the guide groove 921 and the pin positioning plate 41 is less than the length of the pin 8.

[0022] The device automatically feeds the pins through a feeding mechanism, and pushes the pins axially through the locking plate and the pin positioning plate with the help of a push rod. It has a simple structure, accurate positioning, and high assembly efficiency.

[0023] In practical use, for ease of understanding of this utility model, it will be described in conjunction with the accompanying drawings;

[0024] During operation, the box lid is placed on the positioning seat, the limiting block abuts against the front and rear outer walls of the box lid, and the positioning block abuts against the left and right side walls of the box lid. A locking plate is placed in the positioning groove on the upper part of the positioning block. The end of the locking plate with positioning hole I extends into the groove of the pin positioning plate at the edge of the box lid. The positioning hole I on the locking plate corresponds to the center of the positioning hole on the pin positioning plate. Then, the pressing cylinder drives the pressing block to move downwards, pressing the locking plate and the box lid tightly together. At the feeding mechanism, the pins in the hopper slide sequentially into the guide groove of the guide seat, located... The center of the pin at the end of the guide groove corresponds to the through hole on the side wall of the guide groove and the center of the push rod. After the box cover and the locking plate are positioned, the push cylinder drives the push rod to move forward. The push rod pushes the pin to move axially until the pin extends into the positioning hole on the pin positioning plate and the positioning hole I on the locking plate. After assembly, the push rod moves backward to reset. The pin in the guide groove automatically slides down the obliquely set guide groove to the through hole position to cooperate with the next pin assembly. After the pin assembly between the box cover and the locking plate is completed, the pressure block moves up to reset, and the box cover can be directly removed.
