[0023] The preferred embodiments of the present invention are further described in detail with reference to the accompanying drawings.

[0024] like Figure 1-6 The described automatic assembly equipment for chain retaining spring connected chain plates includes a frame 1 and a workbench 2 on the frame 1. A ring-connected chain transfer mechanism 3 is provided under the workbench 2. The ring-connected chain transfer mechanism 3 includes a chain push plate 31, a push plate seat 32 and a driver. The driver is fixed under the workbench 2. The driver adopts a fifth cylinder 33. A moving groove 34 is also provided in the workbench 2. The positioning seat 4 is located on one side of the moving groove 34. The fifth cylinder 33 is connected to the push plate seat 32. The upper side of the push plate seat 32 is connected to the chain push plate 31 located above the workbench 2. The push plate seat 32 is driven by the fifth cylinder 33 to move in the moving groove 34, thereby driving the chain push plate 31 to send the chain to be ring-connected to the front of the positioning seat 4 for positioning. In addition, the head of the positioning seat 4 is provided with at least two positioning grooves 36 adapted to the surface of the chain roller, which are used to position the chain to prevent it from shaking. The head of the chain push plate 31 is provided with two arc grooves 35 adapted to the rollers on the surface of the chain, which is easy to install and more accurate in feeding. The workbench 2 is provided with a positioning seat 4, a spring-clip mechanism 5, a connecting chain plate mechanism 6, a cover mechanism 7 and a spring-clip mechanism 8. The spring-clip mechanism 5 and the connecting chain plate mechanism 6 are installed on the upper side of the positioning seat 4. The connecting chain plate mechanism 6 sends the connecting chain plate to the top of the chain, and the spring-clip mechanism 5 sends the spring to the top of the connecting chain plate. The cover mechanism 7 is located directly above the spring and the connecting chain plate. The spring and the connecting chain plate are pressed into the pin plate through the cover mechanism 7, and the spring-clip mechanism 8 pushes the spring to complete the assembly.

[0025] The spring feeding mechanism 5 includes a spring barrel 51, a spring storage seat 52, a spring feeding plate 53, a connecting rod 54, a fourth cylinder 55 and a third fixed seat 56. The fourth cylinder 55 is connected to one side of the connecting rod 54. The spring feeding plate 53 is embedded on the connecting rod 54. The spring barrel 51 is correspondingly installed on the upper side of the spring storage seat 52. The spring feeding plate 53 and the spring storage seat 52 are movably matched. The fourth cylinder 55 drives the connecting rod 54 and the spring feeding plate 53 to move. The spring feeding plate 53 sends the spring in the spring storage seat 52 to a fixed position and then returns. The spring in the spring barrel 51 drops one grid. After the spring feeding plate 53 pushes the spring to move, the upper part of the spring feeding plate 53 abuts against the spring in the spring barrel 51. After the spring is pushed back to the original position, the spring loses resistance and can drop one grid, thereby performing an automatic feeding cycle.

[0026] The first slide grooves 57 for the movement of the spring feeding plate 53 are arranged on both sides of the inner part of the spring storage seat 52, the clamping grooves 58 matching the surface of the spring sheet are arranged on both sides of the middle of the spring storage seat, and the side of one side of the spring storage seat 52 is provided with a second slide groove 59 that is movably matched with the connecting rod 54. The shape of the clamping groove 58 matches the shape of the spring sheet cylinder 51, which is convenient for the spring to fall in, and the design of the first slide groove 57 is convenient for the movement of the spring feeding plate 53 and the movement of the spring.

The third cylinder 65 is connected to the connecting chain plate feeding plate 63 through the trapezoidal connecting block 64. The connecting chain plate storage seat 61 is installed on the positioning seat 4. The connecting chain plate barrel 62 is correspondingly installed on the upper side of the connecting chain plate storage seat 61. The connecting chain plate storage seat 61 has third slide grooves 66 for the connecting chain plate feeding plate 63 to move on both sides. The third cylinder 65 drives the connecting chain plate feeding plate 63 to move, so that the connecting chain plate in the connecting chain plate storage seat 61 is sent to a fixed position and then returns, and the connecting chain plate in the connecting chain plate barrel 62 drops one grid, which is convenient for feeding the connecting chain plate.

[0028] The cover plate mechanism 7 includes a pressing pin 71, a guide seat 72, a pressing block 73, a second cylinder 74 and a second fixed seat 75. The second fixed seat 75 is installed on the spring push mechanism 8. The second cylinder 74 and the guide seat 72 are installed on the second fixed seat 75. A pressing block 73 is installed at the end of the second cylinder 74. A pressing pin 71 is installed at the end of the pressing block 73. A spring is provided inside the pressing pin 71. The pressing pin 71 can be retracted after encountering resistance. The pressing block 73 moves inside the guide seat 72. The second cylinder 74 pushes the pressing block 73 out. The pressing block 73 moves downward along the inside of the guide seat 72 to press the retaining ring and the connecting chain plate into the inside of the connecting pin plate, which is convenient for ring connection and realizes automation.

[0029] The clamp spring pushing mechanism 8 is composed of a clamp spring pushing block 81, a first fixing seat 82, and a first cylinder 83. The first fixing seat 82 is installed on the side of the workbench 2, the first cylinder 83 is installed on the first fixing seat 82, and the clamp spring pushing block 81 is installed on the end of the first cylinder 83. The clamp spring pushing block 81 is pushed out by the rod of the first cylinder 83 to hit the clamp spring to complete the assembly. The piston rod on the first cylinder 83 passes through the second fixing seat 75, and then the head of the piston rod is fixed to the clamp spring pushing block 81, thereby pushing the clamp spring for assembly.

[0030] A PLC controller is provided on one side of the workbench 2, and the PLC controller is electrically connected to the first cylinder 83, the second cylinder 74, the third cylinder 65, the fourth cylinder 55 and the fifth cylinder 33 respectively. The sequence of each cylinder is controlled by the setting of the PLC controller. Since the principle of cylinder control by the PLC controller is relatively conventional, it will not be described in detail.

[0031] In actual operation, firstly, the chain to be connected is put through the connecting pin and placed in the chain push plate 31. The PLC controller controls the fifth cylinder 33 to drive the chain push plate 31 to send the chain to be connected into the chain positioning seat 4. After the chain to be connected is in place, the PLC controller controls the third cylinder 65 to drive the connecting chain plate feeding plate 63 to push the connecting chain plate in the connecting chain plate storage seat 61 to the specified position. After it is in place, the PLC controller controls the fourth cylinder 55 to drive the retaining spring feeding plate 53 to push the retaining spring storage seat 5 2 is pushed out to the designated position, that is, above the connecting chain plate; after it is in place, the PLC controller controls the second cylinder 74 to push the pressure pin 71 below the pressure block 73 downward, pressing the clamping ring and the connecting chain plate into the connecting pin plate, and after it is retracted, the PLC controller controls the first cylinder 83 to quickly extend and drive the clamping ring push block 81 to directly drive the clamping ring into the pin groove of the connecting pin plate. After completion, the first cylinder 83, the third cylinder 65, the fourth cylinder 55, and the fifth cylinder 33 return to their original positions, completing an action cycle. The present invention realizes the mechanization and automation of the assembly of the chain clamp connecting the chain plate, saves labor, and improves efficiency.
