Description

Technical Field

[0001] The utility model relates to the technical field of connection completed by deformation, in particular to an auxiliary positioning device for a wire harness crimping machine. Background Art

[0002] A wiring harness refers to a contact terminal made of copper material that is crimped with wires and cables, and then an insulator or a metal shell is added to the outside to form a component for connecting circuits. A Chinese utility model patent, authorization announcement number "CN214044291U", discloses an auxiliary positioning device for a wire harness crimping machine, including a crimping tool and a positioning device, the positioning device includes a photoelectric switch, a signal receiving block and a limit bracket; the limit bracket is provided with a through mounting hole, and each mounting hole of the limit bracket is respectively installed with two photoelectric switches, and a first connecting rod and a second connecting rod are fixedly installed on both sides of the crimping tool, and a signal receiving block is respectively fixed on the first connecting rod and the second connecting rod, and the crimping tool is lifted and lowered to drive the signal receiving block to lift and lower, so as to block or reflect the light emitted by the photoelectric switch.

[0003] The above technical solution transmits signals through four photoelectric switches (two tool pressing signals, two tool retracting signals) to indicate the movement of the tool. This can effectively avoid normal crimping work when problems occur in one or two signals, thereby reducing the equipment failure rate. However, the above technical solution still has certain defects. When the driving mechanism drives the crimping tool to move toward the crimping blade to crimp the wire harness, the crimping is rigid crimping. The wire harness is deformed under the direct force of the crimping tool, causing the terminal and the wire to be clamped together. The internal structure of the terminal is prone to cracks, which affects the quality of the wire harness after crimping. For this reason, the utility model proposes a new solution.

[0030] See also Figure 1-4 The utility model provides a technical solution: an auxiliary positioning device for a wire harness crimping machine, comprising a wire harness crimping machine 1, a bracket 2 is fixedly connected to the upper surface of the wire harness crimping machine 1, a fixed seat 17 is fixedly connected to the upper surface of the wire harness crimping machine 1, an electric push rod 3 is fixedly connected inside the bracket 2, two sliding rods 4 are slidably connected inside the bracket 2, and a buffer component is arranged inside the fixed seat 17.

[0031] The buffer assembly includes a sleeve 12, which is fixedly connected to the inside of a fixed seat 17, to which a damper 13 is fixedly connected, to which a limiting plate 14 is slidably connected, and to which an end of the damper 13 close to the limiting plate 14 is fixedly connected, to which an end of the limiting plate 14 away from the damper 13 is fixedly connected, and to which a movable rod 15 is fixedly connected, the movable rod 15 is slidably connected to the sleeve 12, and to which an end of the movable rod 15 away from the sleeve 12 is fixedly connected to a fixed plate connecting plate 16.

[0032] There are two buffer assemblies, both of which are fixedly connected to the inside of the fixed seat 17. The inside of the fixed seat 17 is slidably connected with a tool holder fixing plate 9. The upper ends of the two fixed plate connecting plates 16 are fixedly connected to the tool holder fixing plate 9. Two limiting brackets 10 are fixedly connected to the upper surface of the tool holder fixing plate 9. The upper surface of the tool holder fixing plate 9 is fixedly connected to a crimping tool holder 11.

[0033] The output end of the electric push rod 3 is fixedly connected to a movable plate 5, and the two sliding rods 4 are fixedly connected to the movable plate 5.

[0034] When using the device, first insert the wire into the terminal and place it on the crimping tool seat 11, start the electric push rod 3 to drive the movable plate 5 to descend, and the movable plate drives the two sliding bars 4 to slide inside the bracket 2, so that the electric push rod 3 drives the movable plate 5 to descend stably, the movable plate 5 drives the two connecting rods 6 to descend, the connecting rod 6 drives the tool fixing plate 7 to descend, and the tool fixing plate 7 drives the crimping tool 8 to descend, so that the crimping tool 8 and the crimping tool seat 11 are close to each other to crimp the wire harness, and the tool fixing plate 7 and the inclined surface of the limiting bracket 10 are in contact, so that the crimping machine is convenient to position, and the two inclined surfaces of the crimping tool are squeezed against the corresponding inclined surfaces of the limiting bracket 10, so that the crimping tool seat 11 and the crimping tool 8 can be stably crimped, so that the crimping tool seat 11 and the crimping tool 8 are always kept in the middle.

[0035] When the thrust of the electric push rod 3 is too large, cracks may be generated inside the wiring harness, affecting the quality of the wiring harness after crimping.

The limit bracket 10 drives the tool seat fixing plate 9 to slide inside the fixing seat 17, and the tool seat fixing plate 9 squeezes the fixing plate connecting plate 16.

[0036] Furthermore, compared with the existing auxiliary positioning device, the limit bracket 10 and the tool holder fixing plate are squeezed by the tool fixing plate 7, and the squeezing force is transmitted to the damper 13 through the fixing plate connecting plate 16, and then the damper 13 performs buffering to protect the wiring harness. The wiring harness is deformed when directly subjected to the crimping tool force, so that the terminal and the wire are clamped together to avoid cracks in the internal structure of the terminal, thereby improving the quality of the wiring harness after crimping, improving the protection performance of the device, improving the crimping effect of the device, and improving the practicability of the device.

[0037] By cooperating with the inclined surface at the lower end of the tool fixing plate 7 and the inclined surface at the upper end of the limiting bracket 10, the crimping tool 8 and the crimping tool seat 11 are always kept in the middle position, which is convenient for auxiliary positioning of the wire harness, convenient for crimping the wire harness, and improves the accuracy of the crimping of the device and the crimping quality of the device.

[0038] Working principle: When using the device, first insert the wire into the terminal and place it on the crimping tool seat 11, start the electric push rod 3 to drive the movable plate 5 to descend, and the movable plate drives the two sliding bars 4 to slide inside the bracket 2, so that the electric push rod 3 drives the movable plate 5 to descend stably, and the movable plate 5 drives the two connecting rods 6 to descend, and the connecting rod 6 drives the tool fixing plate 7 to descend, and the tool fixing plate 7 drives the crimping tool 8 to descend, so that the crimping tool 8 and the crimping tool seat 11 are close to each other to crimp the wire harness, and the tool fixing plate 7 and the inclined surface of the limiting bracket 10 are in contact, so that the crimping machine is convenient to position, and the two inclined surfaces of the crimping tool squeeze the corresponding inclined surfaces of the limiting bracket 10, so that the crimping tool seat 11 and the crimping tool 8 can be stably crimped, so that the crimping tool seat 11 and the crimping tool 8 are always kept in the middle.

[0039] When the thrust of the electric push rod 3 is too large, cracks may be generated inside the wiring harness, affecting the quality of the wiring harness after crimping.

Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
