Description

Technical Field

[0001] This utility model relates to the technical field of wire harness crimping, and in particular to a waterproof connector crimping device for sensor wire harnesses. Background Technology

[0002] For some sensors used in humid environments, the wiring harnesses on these sensors need to be crimped with waterproof connectors during processing. In the prior art, utility model patent application number 202421048992.0 discloses an automotive wiring harness terminal crimping device, which mainly consists of a cylinder and a crimping fixture. During use, the stripped wire end of the wiring harness is inserted into the connector, and then pressure is applied to the connector through a pressing mechanism, causing the connector to make tight contact with the wire core on the wiring harness under pressure. However, this device has the following problems: for some waterproof connectors, after crimping, in order to improve the sealing effect between the connector and the wiring harness, it is necessary to install waterproof heat shrink tubing at the connection point. The aforementioned crimping device only has the crimping function and cannot assist workers in installing heat shrink tubing on the connector, resulting in high limitations and inconvenience in its use. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a sensor wire harness waterproof connector crimping device that can not only crimp connectors and wire harnesses, but also assist workers in installing heat shrink tubing on connectors. It is easy to use, has low limitations, and is highly practical.

[0004] This utility model discloses a waterproof connector crimping device for sensor wire harnesses, comprising a bracket, a lower mold, and an upper mold. The lower mold is mounted on the bracket, and the upper mold is located above the lower mold. Both the upper and lower molds are provided with crimping grooves. It also includes a lifting mechanism, a heating mechanism, and a clamping mechanism. The upper mold is mounted on the lifting mechanism, which is used for lifting and lowering the upper mold. The heating mechanism is located on the bracket and has a heating function. The clamping mechanism is mounted on the bracket and has a clamping and fixing function. When it is necessary to crimp a waterproof connector to the end of the wire harness, the connector is first placed in the crimping groove of the lower mold, and then... Insert the end of the wire harness into the connector. Then, the upper mold is lowered by the lifting mechanism, causing the connector to deform under the pressure of the lower and upper molds, making the connector and the end of the wire harness tightly connected. After that, the worker puts the heat shrink tubing on the outside of the connection between the connector and the wire harness. Then, the connector is clamped by the clamping mechanism, and at the same time, the heat shrink tubing on the connector is heated by the heating mechanism, causing the heat shrink tubing to deform and shrink, so that the heat shrink tubing is attached to the connection between the connector and the wire harness. It can not only crimp the connector and the wire harness, but also help the worker install the heat shrink tubing on the connector. It is convenient to use, has few limitations, and is highly practical.

[0005] Preferably, the lifting mechanism includes a support frame, a hydraulic cylinder, a lifting rod, a sliding rod, and a lifting plate. The support frame is fixedly installed on the upper end of the bracket, the hydraulic cylinder is fixedly installed on the upper end of the support frame, and the lifting rod and sliding rod are both slidably installed on the support frame. The power output end of the hydraulic cylinder is connected to the lifting rod, and the lifting plate is fixedly installed on the lower end of the lifting rod and the sliding rod. The upper mold is fixedly installed on the lower end of the lifting plate. When it is necessary to lift the upper mold, the hydraulic cylinder is opened, and the hydraulic cylinder drives the lifting plate to lift the upper mold through the lifting rod, which facilitates the adjustment of the height of the upper mold.

[0006] Preferably, the clamping mechanism includes a pneumatic finger cylinder and a rotating mechanism. The pneumatic finger cylinder is mounted on the rotating mechanism, which is used to rotate the pneumatic finger cylinder. The pneumatic finger cylinder is provided with two clamping plates. When it is necessary to install heat shrink tubing at the connection between the wire harness and the connector, the heat shrink tubing is first placed on the connection between the wire harness and the connector. Then, the connector is clamped and fixed by the two clamping plates on the pneumatic finger cylinder. Finally, the heat shrink tubing is heated by the heating mechanism.

[0007] Preferably, the rotating mechanism includes a support plate and an indexing plate. The support plate is mounted on a bracket, and the indexing plate is fixedly mounted on the support plate. A pneumatic finger cylinder is fixedly mounted on the rotating end of the indexing plate. When heating the heat shrink tubing at the connection between the wire harness and the connector, the indexing plate is opened, and the indexing plate drives the pneumatic finger cylinder and the clamping plate to rotate, thereby causing the wire harness and the heat shrink tubing to rotate, so that all positions in the circumferential direction of the heat shrink tubing can be heated.

[0008] Preferably, the heating mechanism includes a mounting plate and a moving mechanism. The mounting plate is provided with multiple electric heating lamps, and the mounting plate is mounted on the moving mechanism, which is used to move the mounting plate. When the heat shrink tubing on the mating head is heated, the multiple electric heating lamps on the mounting plate are turned on to heat the heat shrink tubing and cause it to shrink.

[0009] Preferably, the moving mechanism includes a base plate, a servo cylinder, and a push rod. The servo cylinder is fixedly mounted on the bracket via the base plate. The power output end of the servo cylinder is provided with a push rod, which is slidably mounted on the support frame. The mounting plate is fixedly mounted on the right end of the push rod. When heating the heat shrink tubing on the wire harness, the servo cylinder is activated. The servo cylinder moves the mounting plate to the right via the push rod, bringing the heating lamp on the mounting plate closer to the heat shrink tubing, so that the distance between the heating lamp and the heat shrink tubing is a suitable distance for heating.

[0010] Preferably, a limit block is provided at the upper end of the sliding rod; this feature prevents the sliding rod from sliding beyond its travel range on the support frame.

[0011] Compared with the prior art, the advantages of this utility model are: it can not only crimp connectors and wire harnesses, but also assist workers in installing heat shrink tubing on connectors. It is convenient to use, has low limitations, and is highly practical. Attached Figure Description

Detailed Implementation

[0014] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0015] Example 1 like Figures 1 to 5The sensor harness waterproof connector crimping device of this utility model includes a bracket 1, a lower mold 2, an upper mold 3, a lifting mechanism, a heating mechanism, and a clamping mechanism. The lower mold 2 is mounted on the bracket 1, and the upper mold 3 is located above the lower mold 2. Both the upper mold 3 and the lower mold 2 are provided with crimping grooves. The upper mold 3 is mounted on the lifting mechanism, which is used to lift and lower the upper mold 3. The heating mechanism is located on the bracket 1 and has a heating function. The clamping mechanism is mounted on the bracket 1 and has a clamping and fixing function. When it is necessary to crimp a waterproof connector to the end of the harness, the connector is first placed in the crimping groove of the lower mold 2. The process involves inserting the end of the wire harness into the connector, then lowering the upper mold 3 via a lifting mechanism. This causes the connector to deform under the pressure of the lower mold 2 and the upper mold 3, tightly connecting the connector to the end of the wire harness. The operator then places the heat shrink tubing over the connection between the connector and the wire harness. A clamping mechanism holds the connector, while a heating mechanism heats the heat shrink tubing on the connector, causing it to deform and shrink, thus adhering to the connection between the connector and the wire harness. This method not only crimps connectors and wire harnesses but also assists operators in installing heat shrink tubing onto connectors. It is convenient to use, has few limitations, and is highly practical.

[0016] like Figure 1 and Figure 3 The lifting mechanism includes a support frame 4, a hydraulic cylinder 5, a lifting rod 6, a sliding rod 7, and a lifting plate 8. The support frame 4 is fixedly installed on the upper end of the bracket 1. The hydraulic cylinder 5 is fixedly installed on the upper end of the support frame 4. The lifting rod 6 and the sliding rod 7 are both slidably installed on the support frame 4. The power output end of the hydraulic cylinder 5 is connected to the lifting rod 6. The lifting plate 8 is fixedly installed on the lower end of the lifting rod 6 and the sliding rod 7. The upper mold 3 is fixedly installed on the lower end of the lifting plate 8. When it is necessary to lift the upper mold 3, the hydraulic cylinder 5 is opened. The hydraulic cylinder 5 drives the lifting plate 8 to lift the upper mold 3 through the lifting rod 6. This facilitates the adjustment of the height of the upper mold 3.

[0017] like Figure 1 and Figure 4 The clamping mechanism includes a pneumatic finger cylinder 9 and a rotating mechanism. The pneumatic finger cylinder 9 is mounted on the rotating mechanism, which is used to rotate the pneumatic finger cylinder 9. Two clamping plates 10 are provided on the pneumatic finger cylinder 9. When it is necessary to install heat shrink tubing at the connection between the wire harness and the connector, the heat shrink tubing is first placed on the connection between the wire harness and the connector. Then, the connector is clamped and fixed by the two clamping plates 10 on the pneumatic finger cylinder 9. Finally, the heat shrink tubing is heated by the heating mechanism.

[0018] like Figure 4The rotating mechanism includes a support plate 11 and an indexing plate 12. The support plate 11 is mounted on the bracket 1, and the indexing plate 12 is fixedly mounted on the support plate 11. The pneumatic finger cylinder 9 is fixedly mounted on the rotating end of the indexing plate 12. When heating the heat shrink tubing at the connection between the wire harness and the connector, the indexing plate 12 is opened, and the indexing plate 12 drives the pneumatic finger cylinder 9 and the clamping plate 10 to rotate, thereby causing the wire harness and the heat shrink tubing to rotate, so that each position in the circumferential direction of the heat shrink tubing can be heated.

[0019] like Figure 1 and Figure 4 The heating mechanism includes a mounting plate 13 and a moving mechanism. The mounting plate 13 is equipped with multiple electric heating lamps. The mounting plate 13 is mounted on the moving mechanism, which is used to move the mounting plate 13. When the heat shrink tubing on the mating head is heated, the multiple electric heating lamps on the mounting plate 13 are turned on to heat the heat shrink tubing, causing it to shrink.

[0020] The moving mechanism includes a base plate 14, a servo cylinder 15, and a push rod 16. The servo cylinder 15 is fixedly mounted on the bracket 1 via the base plate 14. The power output end of the servo cylinder 15 is provided with a push rod 16. The push rod 16 is slidably mounted on the support frame 4. The mounting plate 13 is fixedly mounted on the right end of the push rod 16. When heating the heat shrink tubing on the wire harness, the servo cylinder 15 is turned on. The servo cylinder 15 moves the mounting plate 13 to the right via the push rod 16, bringing the heating lamp on the mounting plate 13 closer to the heat shrink tubing, so that the distance between the heating lamp and the heat shrink tubing is a suitable distance for heating.

[0021] Example 2 Based on Embodiment 1, a limit block 17 is provided at the upper end of the sliding rod 7; through the above setting, the sliding rod 7 is prevented from sliding beyond its travel on the support frame 4.

[0022] It should be added that: all electrical equipment in this case is connected to an external controller, which coordinates and controls the operation of each piece of electrical equipment.
