[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1, please refer to Figures 1-6 The present invention provides a technical solution: a testing device for the development of wiring harnesses for marine generator control boxes, comprising a base 1, a motor 101 fixedly connected to the outer wall of the base 1, a cover plate 102 connected to the outer wall of the base 1 via a hinge, and a support plate 103 fixedly connected to the inner wall of the base 1, and further comprising:

[0031] Clamping mechanism 2 is disposed on the surface of support plate 103. Clamping mechanism 2 includes support plate 201. The outer wall of support plate 201 is hinged to hinge plate 202 via hinge block. Support block 1 204 is hinged to the outer wall of hinge plate 202. Clamping sleeve 203 is fixedly connected to the outer wall of support block 1 204. Support block 205 is fixedly connected to the outer wall of support plate 103. Limit block 1 211 is fixedly connected to the outer wall of clamping sleeve 203. The outer wall of limit block 1 211 is slidably connected to the wall of sliding groove 1 212 opened on the outer wall of positioning plate 206. Support block 3 207 is fixedly connected to the outer wall of positioning plate 206. Anti-detachment mechanism 3 is provided on the outer wall of clamping sleeve 203. Clamping sleeve 203 is used for... When the testing device for the wire harness of the ship's generator control box is put into use, the positioning plate 206 is clamped, causing the positioning plate 206 to compress the spring 210 and drive the support rod 209 to slide on the inner wall of the guide groove 214. The clamping sleeve 203 is supported by the support block 204 and the hinge plate 202, causing the limiting block 211 to slide to both sides on the inner wall of the sliding groove 212, so that the clamping sleeve 203 opens. The wire harness is then passed through the positioning plate 206 and the support plate 201, and the wire is fixed to the outer wall of the testing block 104. The positioning plate 206 is then released, causing the spring 210 to press the positioning plate 206, causing the positioning plate 206 to drive the support rod 209 to slide on the inner wall of the guide groove 214. The clamping sleeve 203 is hinged to the hinge plate 202 via the support block 204, causing the clamping sleeve 203 to slide the limiting block 211 on the inner wall of the sliding groove 212 and move towards the wire harness, so that the inner wall of the clamping sleeve 203 contacts the outer wall of the wire harness. At the same time, the distance between the support plate 201 and the positioning plate 206 increases, so that the anti-detachment mechanism 3 is guided by the guide groove 213 to clamp the wire harness to prevent it from detaching. After the clamping mechanism 2 clamps the wire harness, the cylinder 107 is activated to drive the gripper 106 to clamp and fix the wire harness. The detection block 104 is activated to perform an electrical test on the wire harness, and the heating block 108 is activated to heat the wire harness. The motor 101 is activated, and the output end of the motor 101 rotates to drive the support plate. The second 201 slides along the inner wall of the first support plate 103 toward the motor 101. The friction generated by the inner wall of the clamping sleeve 203 on the wire harness causes the second support plate 201 to move toward the motor 101. The clamping sleeve 203 is supported by the hinge plate 202 and the anti-detachment mechanism 3. During the pulling process, the wire harness drives the clamping claw 106 to transmit the pulling force to the second detection block 105 to detect the pulling force. At the same time, the resistance change of the wire harness generated during the increase of pulling force and temperature is detected and judged by the first detection block 104. After the detection is completed, the clamping sleeve 203 and the anti-detachment mechanism 3 are released from the clamping of the multiple wire harnesses by pressing the positioning plate 206. The wire harness that has been tested is removed and waits for the next test.

[0032] The outer wall of the support plate 201 has a guide groove 214, and the outer wall of the clamping sleeve 203 has a guide groove 213. A limiting groove 208 is formed in the wall of the sliding groove 212. A support rod 209 is fixedly connected to the outer wall of the positioning plate 206, and a spring 210 is fixedly connected to the outer wall of the positioning plate 206. The other end of the spring 210 is slidably connected to the inner wall of the support plate 201. The support rod 209 is used to limit the positioning plate 206, so that the positioning plate 206 supports the positioning plate 206 during the sliding process of the spring 210 within the guide groove 214, preventing the positioning plate 206 from tilting and guiding the clamping sleeve 203, thus preventing the wire harness from being clamped at an angle. 06. Supported by spring 210, the distance between the clamping sleeve 203 and the support plate 201 is increased, allowing the clamping sleeve 203 to be supported by the hinge plate 202. This causes the limiting block 211 to slide on the inner wall of the sliding groove 212, making the inner wall of the clamping sleeve 203 contact the outer wall of the wire harness and clamp the wire harness. At the same time, when the support plate 201 pulls the wire harness through the clamping sleeve 203 to perform a tensile test, the friction generated between the inner wall of the clamping sleeve 203 and the outer wall of the wire harness causes the clamping sleeve 203 to slide on the inner wall of the support plate 201. The clamping sleeve 203 is supported by the hinge plate 202, increasing the clamping force of the clamping sleeve 203 on the wire harness, thus matching the clamping force of the clamping sleeve 203 on the wire harness with the tensile force.

[0033] A detection block 104 is fixedly connected to the inner wall of the base 1. A detection block 105 is fixedly connected to the surface of the support plate 103. A gripper 106 is slidably connected to the top of the detection block 105. The outer wall of the gripper 106 is fixedly connected to the output end of the cylinder 107. A heating block 108 is fixedly connected to the surface of the support plate 103. The gripper 106 is used to clamp the wire harness. After the clamping mechanism 2 clamps the wire harness, the cylinder 107 is started to drive the gripper 106 to clamp and fix the wire harness. The detection block 104 is started to perform an electrical test on the wire harness, and the heating block 108 is started to heat the wire harness. The motor 1 is started. 01. The output end of motor 101 rotates, causing support plate 201 to slide on the inner wall of support plate 103 towards motor 101. The friction generated by the inner wall of clamping sleeve 203 on the wire harness causes support plate 201 to move towards motor 101. The clamping sleeve 203 is supported by hinge plate 202 and anti-disengagement mechanism 3. During the pulling process, the wire harness drives the clamping claw 106 to transmit the pulling force to detection block 2 105 to detect the pulling force. At the same time, detection block 104 detects and judges the resistance change of the wire harness during the increase of pulling force and temperature.

[0034] The inner wall of support plate 201 is connected to the output end of motor 101 via threads. There are two sets of hinge plates 202, clamping sleeves 203, and support blocks 204. These two sets of hinge plates 202, clamping sleeves 203, and support blocks 204 are symmetrically arranged on both sides of support plate 201 with the center line as the axis of symmetry. The bottom of the outer wall of support plate 201 is slidably connected to the inner wall of support plate 103. The outer wall of limiting block 211 is slidably connected to the wall of limiting groove 208 via a slider. The outer wall of clamping sleeve 203... The wall is slidably connected to the inner wall of the support plate 201. The hinge plate 202 is used to support the clamping sleeve 203. The clamping sleeve 203 is hinged to the hinge plate 202 through the support block 204, so that the clamping sleeve 203 drives the limiting block 211 to slide on the inner wall of the sliding groove 212 and move towards the wire harness, so that the inner wall of the clamping sleeve 203 contacts the outer wall of the wire harness. At the same time, the distance between the support plate 201 and the positioning plate 206 increases, so that the anti-detachment mechanism 3 is guided by the guide groove 213 to clamp the wire harness to prevent detachment.

[0035] There are two sets of support rods 209 and springs 210. The two sets of support rods 209 and springs 210 are symmetrically arranged on the outer wall of the positioning plate 206 with the center line of the positioning plate 206 as the axis of symmetry. The outer wall of the support rods 209 is slidably connected to the wall of the guide groove 214. The guide groove 214 is used to guide the support rods 209 so that the positioning plate 206 supports the positioning plate 206 during the process of the springs 210 sliding in the inner wall of the guide groove 214, and prevents the positioning plate 206 from tilting and guiding the clamping sleeve 203, which would cause the wire harness to tilt and be clamped.

[0036] The outer wall of cylinder 107 is fixedly connected to the inner wall of base 1. There are two sets of cylinder 107 and gripper 106. The two sets of cylinder 107 and gripper 106 are symmetrically arranged on the inner wall of base 1 with the center line of support plate 103 as the axis of symmetry. Detection block 104 is used to test the resistance of wire harness, detection block 205 is used to test the tensile force of wire harness, and heating block 108 is used to simulate high temperature environment to test wire harness performance. During the pulling process, the wire harness drives the gripper 106 to transmit the tensile force to detection block 205 to detect the tensile force. At the same time, the resistance change of the wire harness generated during the increase of tensile force and temperature is detected and judged by detection block 104.

[0037] Example 2, based on Example 1, please refer to... Figure 7-Figure 8The present invention provides a technical solution: the anti-detachment mechanism 3 includes a swing block 307, the outer wall of the swing block 307 is hinged to the outer wall of the support block 207 via a rotating shaft, the bottom of the swing block 307 is hinged to a support plate 301 via a rotating shaft, the outer wall of the support plate 301 is fixedly connected to a support rod 302, the outer wall of the support rod 302 is slidably connected to a limit block 303, the outer wall of the limit block 303 is fixedly connected to a spring 304, the other end of the spring 304 is fixedly connected to the outer wall of the support plate 301, the outer wall of the support rod 302 is slidably connected to the sliding groove 306 opened on the outer wall of the clamping block 305 via a slider, the outer wall of the clamping block 305 is fixedly connected to an anti-sliding block 308, the clamping block 305 is used to clamp the wire harness, the spring 1 squeezes the positioning plate, and the clamping sleeve 203 clamps the wire harness during the process, the positioning plate 206 and the support plate 201 As the spacing increases, the swing block 307 is hinged to the support block 205 and the support block 307, causing the swing block 307 to swing and compensate for the displacement of the positioning plate 206. At the same time, the support plate 301 compresses the spring 204 and slides on the inner wall of the limit block 203. The support plate 301 drives the clamping block 305 to slide on the inner wall of the guide groove 1 213 through the support rod 202, clamping the wire harness. During the process of the clamping block 305 squeezing the anti-slip block 308, friction is generated. During the pulling process, the clamping block 305 slides on the outer wall of the support rod 202 through the friction with the outer wall of the wire harness, supporting the clamping sleeve 203. The clamping sleeve 203 is supported by the hinge plate 202, increasing the clamping force on the wire harness and preventing the clamping sleeve 203 and clamping block 305 from slipping on the outer wall of the wire harness during the tensile test.

[0038] The outer wall of clamping block 305 is slidably connected to the wall of guide groove 213. There are two sets of anti-detachment mechanisms 3, symmetrically arranged on both sides of positioning plate 206 with the center line of positioning plate 206 as the axis of symmetry. There are four sets of swing blocks 307. The two sets of swing blocks 307 located at the bottom of support block 205 are symmetrically arranged on both sides of support plate 201 with the center line of support plate 201 as the axis of symmetry, and are connected to the bottom of support block 205 via a hinge through a rotating shaft. The two sets of swing blocks 307 located at the bottom of support block 307 are symmetrically arranged on both sides of positioning plate 206 with the center line of positioning plate 206 as the axis of symmetry. Symmetrically arranged on both sides of the positioning plate 206, the support plate 301 is used to support the clamping block 305 through the support rod 202. During the process of the clamping block 305 squeezing the anti-sliding block 308, friction is generated, so that when the wire harness is pulled, the clamping block 305 slides on the outer wall of the support rod 202 through the friction with the outer wall of the wire harness, supporting the clamping sleeve 203. The clamping sleeve 203 is supported by the hinge plate 202, which increases the clamping force on the wire harness and prevents the clamping sleeve 203 and the clamping block 305 from slipping on the outer wall of the wire harness during the tensile test.
