DETAILED DESCRIPTION

[0026] The present application will be further described in detail below in conjunction with specific embodiments and by referring to the drawings. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope of the present application and its applications.

[0027] With reference to the following drawings, non-limiting and non-exclusive embodiments will be described, in which the same reference numerals indicate the same parts, unless otherwise specified.

[0028] As Figures 1-3 shown in one kind of steel wire rope chuck punch riveting automatic error-proof device, proximity switch 6, positioning block 8, support 25, bending rod, shaft moving piece 29, the upper part of positioning block 8 is equipped with assembly hole, shaft moving piece 29 is slidably installed in the assembly hole.The left side of the upper part of positioning block 8 is also equipped with the support 25 corresponding to the position of the assembly hole, the left side of the support 25 is equipped with a limit plate 252, a certain length of containing space 251 is formed between the limit plate 252 and the positioning block 8, and the containing space 251 is communicated with the assembly hole.The bending part 20 of the bending rod is rotatably installed on the upper part of the support 25 by the pin shaft 21, the shorter end of which extends into the containing space 251 between the limit plate 252 and the positioning block 8 and abuts against the left end of the shaft moving piece 29, and the longer end extends away from the support 25 and extends below the proximity switch 6.Specifically, the bending rod includes a touch rod 19 and a top contact rod 30, the junction of the touch rod 19 and the top contact rod 30 forms the bending part 20, the bending part 20 is rotatably installed on the support 25 by the pin shaft 21, forming a lever mechanism with the pin shaft 21 as the fulcrum, the touch rod 19 as the long arm and the top contact rod 30 as the short arm.The other end of the touch rod 19 extends below the proximity switch 6, and the other end of the top contact rod 30 extends into the containing space 251.In this way, when the shaft moving piece 29 pushes the top contact rod 30 to move left, the bending rod rotates clockwise around the pin shaft 21 under the action of the lever, so that the touch rod 19 is raised upward and contacts the proximity switch 6, thereby triggering the relay to work and controlling the punch riveter to perform a punch riveting operation.In general, the main technical concept of the scheme is to drive the bending rod to rotate by moving the shaft moving piece 29, so that the touch rod 19 is raised and contacts the proximity switch, thereby activating the punch riveter to perform a punch riveting operation.Preferrably, the shaft moving piece 29 includes a mandrel 24.

[0029] The working principle of the error-proof device is as follows: the length of the contact rod 19 is much greater than the length of the top rod 30, and in normal state, the contact rod 19 sinks under the weight, and the bent rod rotates counterclockwise around the pin shaft 21, so that the left end surface of the top rod 30 and the shaft moving part 29 abuts. The receiving space 251 formed by the limiting plate 252 and the positioning block 8 limits the angle of rotation of the bent rod around the pin shaft 21, and at the same time, the distance between the proximity switch 6 and the contact rod 19 is adjusted, so that when the shaft moving part 29 pushes the top rod 30 to the left, and the shaft moving part 29 moves 1mm to the left, the contact rod 19 is raised upward and just contacts the proximity switch 6, thereby triggering the relay to work, controlling the punch riveter to perform a punch riveting operation, and the steel wire rope 16 and the chuck 15 on the punch riveter are pressed and riveted, and the steel wire rope 16 is exposed from the chuck by 1mm. In this way, it can be ensured that the shaft moving part 29 can only activate the relay to work when it moves a sufficient distance, thereby activating the control of the punch riveter to perform a punch riveting operation, and ensuring the exposure size of the steel wire rope 16. If the shaft moving part 29 does not move in place, the height of the contact rod 19 is not enough to contact the proximity switch 6, and the relay does not work, thereby achieving the error-proof effect.

[0030] Further, the shaft moving part 29 further comprises a guide pipe 23 and a fastening screw 22, the guide pipe 23 is installed in the assembly hole and is fixed by the fastening screw 22 to prevent the guide pipe 23 from loosening or moving. The core rod 24 is slidingly assembled in the guide pipe 23, and the left end surface of the core rod 24 is flush with the left end surface of the guide pipe 23. As a preferred embodiment, the length of the core rod 24 is equal to the length of the guide pipe 23. When the guide pipe 23 is installed, the left end surface of the guide pipe 23 can be flush with the left side of the positioning block 8, or can extend into the receiving space 251, and the distance between the limiting plate 252 and the guide pipe 23 is adjusted, thereby adjusting the angle of rotation of the top rod 30 in the receiving space 251. Further, the core rod 24 is a stepped column structure with large and small ends, and correspondingly, the guide pipe 23 is provided with a stepped cavity matching the structure of the core rod 24, and the large end of the core rod 24 is close to the bracket 25 to prevent the core rod 24 from coming out of the guide pipe 23. The guide pipe 23 serves as a guide for the core rod 24 and also serves as a positioning for the chuck 15, and when punch riveting, the left end surface of the chuck 15 abuts against the right end surface of the guide pipe 23 to position the chuck 15.

[0031] The preferred embodiment of the above technical solution can adjust the swing range of the top rod 30 through the mobile guide pipe 23, but if the guide pipe 23 is positioned and then adjusted again, the positioning of the chuck 15 and the exposed length of the steel wire rope 16 will be affected. Therefore, a threaded hole is formed in the limiting plate 252 to connect the adjusting bolt 26, the front end of the adjusting bolt 26 has a certain distance from the top rod 30, and the distance can be changed by rotating the adjusting bolt 26, thereby compensating for the inconvenience of adjusting after the guide pipe 23 is positioned. The purpose of limiting the swing range of the top rod 30 is to prevent the touch rod 19 from hitting the proximity switch 6 when the touch rod 19 is in contact with the proximity switch 6.

[0032] In the above technical solution, it can be known that the error-proof device uses the principle of the effort lever mechanism, uses the small movement of the top rod 30 to drive the large movement of the touch rod 19, and can also prevent the touch rod 19 from accidentally touching the proximity switch 6. However, there is a problem that the touch rod 19 is too long, which not only increases the installation distance of the proximity switch 6, but also is easy to bend and deform. The embodiment further optimizes the spring 31 sleeved outside the adjusting bolt 26, and the spring 31 is arranged between the limiting plate 252 and the top rod 30 and has a spring force acting on the top rod 30. By arranging the spring 31, the length of the touch rod 19 can be reduced, and the spring 31 can also unload the touch rod 19 after descending, reduce the swing range and time of the touch rod 19, and make the touch rod 19 more stable.

[0033] Regarding the bracket 25, the bracket 25 is a U-shaped block structure, the upper part of the two side walls is provided with a mounting hole 253 penetrating through both sides for assembling the pin shaft, one port is connected with the positioning block 8, and the opposite port is provided with the limiting plate 252. The bent rod is assembled to the bracket 25 through the pin shaft 21, and the top rod 30 of the bent rod extends to the accommodating space 251. Preferably, the right part of the bracket 25 extends out a connecting part 28, the connecting part 28 is provided with an axial screw hole, and the left part of the guide pipe 23 is provided with an external thread connected with the screw hole. In this way, the bracket 25 and the guide pipe 23 are screw-connected, and then the guide pipe 23 is assembled into the positioning block 8 to be clamped, thereby improving the assembly of the error-proof device.

[0034] In the above technical solution, in order to facilitate disassembly and maintenance, the bent rod further comprises a rotating block, the rotating block is a bending part 20 of the bent rod, the touch rod 19 and the top rod 30 are respectively screw-connected and fixed to the rotating block, and the bent rod has an L-shaped structure or a V-shaped structure.

[0036] The utility model provides a steel wire rope clamp head punch riveter's use method, including the following steps: operator passes the steel wire rope 16 in the hole of clamp head 15, then places clamp head 15 in the half hexagonal groove of lower die 9, and the left end surface of clamp head 15 is abutted to the right end surface of guide pipe 23, pushes the steel wire rope 16 to the side of error-proofing device 7, makes the left end of steel wire rope 16 abut against the right end surface of core rod 24, and pushes core rod 24 to the left and abuts against lever 30, in turn drives the rotation of bending lever, and touch lever 19 is raised and contacts proximity switch 6, in turn triggers the work of relay, controls punch riveter to carry out once punch riveting operation, and the riveting of steel wire rope 16 and clamp head 15 is completed.
