Description

Technical Field

[0001] The utility model relates to the technical field of wire harness positioning equipment, in particular to a positioning equipment for tension testing of a vehicle door wire harness. Background Art

[0002] Door wiring harnesses usually require tension testing during the manufacturing process. During the tension testing of the wiring harnesses, it is generally necessary to clamp and fix the wiring harnesses in advance, and then perform tension testing on the positioned wiring harnesses through the corresponding detection device.

[0003] Existing harness positioning equipment generally directly presses both sides of the harness by using a clamp block in cooperation with a driving mechanism that drives the clamp block, thereby completing the positioning of a designated harness.

[0004] However, when the wire harness is positioned by the existing positioning equipment in the above manner, due to the large variety of wire harness sizes, when the wire harnesses with large diameter differences are clamped and fixed, the center positions of the wire harnesses with different diameters will be offset. Therefore, in the subsequent tensile test, the direction of the tensile force cannot be consistent with the wire harness body, resulting in large errors in the test results. Utility Model Content

[0005] The purpose of the utility model is to provide a positioning device for a tension test of a vehicle door wiring harness, which can adjust the actual fixed position of the wiring harness according to the different diameters of the wiring harness through the provided components, so that the fixed position of the wiring harness can be consistent with the tension direction of the tension test mechanism, thereby reducing the error of the test result.

[0006] To achieve the above-mentioned purpose, the utility model provides a positioning device for testing the tension of a door harness, comprising a support base and a working component;

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0020] The first embodiment of the present application is:

[0021] See also Figures 1 to 3 ,in Figure 1 This is a schematic diagram of the overall structure of the positioning equipment for the tension test of the door harness.

[0022] The utility model provides a positioning device for a tension test of a door harness: comprising a supporting base 101 and a working component, wherein the working component comprises a connecting frame 102, a lifting frame 103, a driving plate 104, a clamping block 105, a compression spring 106, a driving component, a clamping component and an auxiliary component, wherein the driving component comprises a lifting screw 107, a lifting motor 108 and a driving component, wherein the clamping component comprises a fixing bracket 109, a pressing cylinder 110 and a clamping plate 111, and wherein the driving component comprises a bidirectional screw rod 112 and a driving motor 113. The above-mentioned scheme solves the problem that the actual fixed position of the harness can be adjusted accordingly according to different diameters of the harness by means of the provided components, so that the fixed position of the harness can be kept consistent with the tension direction of the tension test mechanism, thereby reducing the error of the test result.

[0023] In this embodiment, the support base 101 is directly placed on a corresponding operating platform or the ground to facilitate the installation of subsequent mechanisms and to support the entire structure after installation.

The lifting frame 103 is movably installed on the connecting frame 102, and two driving plates 104 are slidably installed on the upper surface of the lifting frame 103, and the clamping block 105 is slidably installed on each of the driving plates 104, and the compression spring 106 is arranged in the guide groove connecting the clamping block 105 and the driving plate 104, so that when the user fixes the wiring harness, he can first clamp the two sides of the wiring harness by moving the driving plates 104 on both sides, and then press down and fix the clamped wiring harness through the clamping member. When pressing down, the clamping block 105 will move downward due to the continuous downward pressure of the clamping member, thereby compressing the compression spring 106. When the test is completed, the clamping member no longer compresses the wiring harness, and the clamping block 105 can be reset under the action of the compression spring 106.

[0025] Secondly, the lifting screw 107 is threadedly connected to the lifting frame 103 and is rotatably installed on one side of the connecting frame 102; the output shaft of the lifting motor 108 is connected to the lifting screw 107, and the lifting motor 108 is fixedly installed on one side of the connecting frame 102; the driving component is connected to the driving plate 104, the lifting screw 107 is adapted to the threaded hole provided on the lifting frame 103, and the lifting screw 107 is fixed to the output shaft of the lifting motor 108. When the lifting motor 108 drives the lifting screw 107 to rotate, the lifting frame 103 can be driven by the rotation of the lifting screw 107, thereby adjusting the supporting height of the lifting frame 103.

[0026] At the same time, the fixed bracket 109 is fixedly connected to the lifting frame 103 and is located on one side of the lifting frame 103; the downward pressing cylinder 110 is connected to the fixed bracket 109 and is located on one side of the fixed bracket 109; the clamping plate 111 is connected to the output end of the downward pressing cylinder 110 and is located on one side of the downward pressing cylinder 110, the fixed bracket 109 is fixedly arranged on the top of the lifting frame 103, the downward pressing cylinder 110 is installed on the fixed bracket 109, and the clamping plate 111 is fixed to the output end of the downward pressing cylinder 110, so that when it is necessary to clamp and fix the wiring harness on the surface of the lifting frame 103, the user can directly drive the clamping plate 111 to move downward through the downward pressing cylinder 110, and the wiring harness is clamped and fixed by the continuous downward movement of the clamping plate 111.

[0027] In addition, the bidirectional screw rod 112 is threadedly connected to the driving plate 104 and is rotatably installed on one side of the lifting frame 103; the output shaft of the driving motor 113 is connected to the bidirectional screw rod 112, and the driving motor 113 is fixedly installed on one side of the lifting frame 103, and the bidirectional screw rod 112 is arranged in a sliding groove of the lifting frame 103 for slidingly installing the driving plate 104, and the threads on both sides of the bidirectional screw rod 112 are arranged in opposite directions, and the two driving plates 104 slidably installed on the lifting frame 103 are symmetrically arranged on both sides of the bidirectional screw rod 112. At the same time, the driving plate 104 is also provided with a threaded hole matching the bidirectional screw rod 112, and the bidirectional screw rod 112 is fixed to the output shaft of the driving motor 113. When the driving motor 113 drives the bidirectional screw rod 112 to rotate, the driving plates 104 on both sides of the lifting frame 103 can be expanded or moved together towards both sides under the action of the bidirectional screw rod 112, thereby completing the clamping of both sides of the wiring harness placed on the surface of the lifting frame 103.

[0028] When the positioning device for testing the tension of the wiring harness of a vehicle door of the present embodiment is used, the driving motor 113 cooperates with the bidirectional screw rod 112 to drive the driving plates 104 on both sides of the lifting frame 103, and then the clamping blocks 105 provided above the driving plates 104 are used to clamp and limit the two sides of the wiring harness, and then the pressing plate 111 is driven downward by the pressing cylinder 110, and the wiring harness placed on the lifting frame 103 is pressed and fixed by the continuous downward movement of the pressing plate 111. In the process of the pressing plate 111 moving downward, the clamping block 105 will be pressed due to the pressure. The tightening plate 111 is pressed down to partially shrink, so that the positioning of the wire harness after clamping is more stable. If the diameter of the wire harness is significantly different from the diameter of the wire harness detected before, the user can directly drive the lifting frame 103 through the lifting motor 108 and the lifting screw 107 according to the actual detection situation, so as to adjust the matching height of the wire harness after clamping, so that the actual fixed position of the wire harness can be adjusted accordingly according to the different diameter sizes of the wire harness through the provided components, so that the fixed position of the wire harness can be consistent with the tension direction of the tension test mechanism, thereby reducing the error of the test result.

[0032] When using a positioning device for testing the tension of a door harness, the infrared emitting device 202 installed on the mounting bracket 201 can be used to more accurately assist in positioning the clamped harness.
