Description

Technical Field

[0001] The utility model belongs to the technical field of wire harness test benches, and in particular relates to a new energy kart belt rolling installation test bench. Background Art

[0002] The new energy wiring harness kart rolling test bench is mainly used to test and verify whether the number of karts and the installation position on the wiring harness of new energy vehicles are correct. In new energy vehicles, the wiring harness is a key component that connects various electrical components. The automotive wiring harness is usually equipped with several kart rolling strips. The kart part is used to snap on the mounting parts of the vehicle, and the rolling strip part at the other end is used to connect and fix the wiring harness so that the wiring harness can be stably installed on the vehicle. The number and size of karts at different positions on the wiring harness must strictly correspond to the vehicle installation point. The number and signal of kart rolling strips are directly related to the reliability of the wiring harness installation. Therefore, strict testing and verification of new energy wiring harnesses and connectors is very necessary.

[0003] A general inspection table and an inspection base are provided. Drawings of the corresponding positions of the wiring harness structure and the inspection base are pasted on the inspection table. Several inspection bases are arranged at different positions on the inspection table according to the drawings. The inspection slots on the inspection base at each corresponding position correspond one-to-one to the wiring harness kart rolling bands on the wiring harness under the standard state. The inspection bases at different positions on the inspection table are used to inspect whether the kart rolling bands on the wiring harness are installed correctly. However, the existing general wiring harness tie tables can only inspect the number and position of kart rolling bands, but do not have the function of simultaneously inspecting the quality of kart rolling bands. Using other test tables to inspect the tie bands again will reduce efficiency. In addition, kart rolling bands are generally made of plastic or rubber. Therefore, there are errors in the production process, which may result in the inability to be installed in the body mounting hole due to excessive size when installed on the body, or looseness after installation due to small size. When such defects are detected, they must be returned for repair, which reduces production progress and efficiency.

[0004] Based on this, it is necessary to design a kart rolling strip installation test bench that can simultaneously perform overall inspection on the quantity and quality of the kart rolling strip. Utility Model Content

[0005] In order to solve the problem in the prior art that the testing platform cannot adjust the position of the testing base according to different situations, resulting in the need to set up multiple testing platforms to meet the usage, the utility model provides a new energy kart belt rolling installation test platform.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0009] Furthermore, the detection mechanism also includes a pulling-out assembly, which includes a plurality of elastic rods and a plurality of rollers. The bottom of the elastic rod is arranged on the short plate section, and the roller is rotatably connected to the top of the elastic rod. The pulling-out assembly swings in the abutting direction of the kart, and the roller is used to assist in pulling out the kart.

[0010] Furthermore, a surface of the detection plate close to the outer side of the detection channel is a curved surface.

[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0023] like Figure 1-6As shown, a new energy kart rolling belt installation test bench of the utility model comprises a test bench body 1 and a plurality of detection bases 2, a plurality of elliptical grooves 9 are provided on the test bench body 1, a slider is provided at the bottom of the detection base 2 for detachably connecting to the elliptical groove 9, the detection base 2 comprises a shell and a detection mechanism, the detection mechanism comprises a push-in component, a detection channel 3 is provided on the side of the shell, the push-in component is arranged in the detection channel 3, the push-in component comprises an outer frame, a plurality of sliding grooves are provided on the inner side of the outer frame, a detection plate 5, a spring 4 and a distance sensor are arranged in each of the plurality of sliding grooves, the detection plate 5 is slidably arranged in the sliding groove, one end of the spring 4 is connected to the bottom of the sliding groove, and the other end is connected to the bottom of the detection plate 5, one end of the distance sensor is connected to the bottom of the sliding groove, and the other end is connected to the bottom of the detection plate 5, a plurality of detection plates 5 slide open and close to form detection holes, and a plurality of distance sensors are used to obtain detection hole size data;

[0024] Since the kart 8 part on the kart rolling strip is an umbrella-shaped structure, the existing equipment only detects one side of the kart 8 when detecting the number and model size of the kart rolling strip on the wire harness, that is, the detection equipment is a semi-arc groove, and one side of the kart 8 is placed in the semi-arc groove for detection during detection. However, this detection method will cause a problem, that is, the kart rolling strip may be of different sizes, and there may be production errors on both sides of the kart 8 part of the same kart rolling strip. After the error occurs, if the size of the kart 8 is smaller than the standard size, it is easy to become loose after being installed on the car. If the size of the kart 8 is larger than the standard size, it is easy to be unable to be installed on the car. Therefore, only one side of the kart 8 is detected, which may produce unqualified wire harnesses, resulting in rework when installed on the car, resulting in reduced production efficiency.

[0025] Therefore, by arranging a push-in assembly in the detection channel 3 of the detection base 2, a spring 4 is arranged under the detection plate 5 of the push-in assembly, so that the detection plate 5 moves in the sliding groove along the elastic force direction of the spring 4, and a plurality of detection plates 5 are simultaneously directed toward the center of the detection channel 3, so that a detection hole is formed in the middle of the plurality of detection plates 5, so that the card 8 of the card rolling strip is inserted into the detection channel 3 from the detection hole. Since the card 8 is an umbrella-shaped structure, the top of the card 8 will gradually push open the surrounding detection plates 5 when inserted into the detection hole, so that the detection plate 5 is subjected to the component force of the pressure of the card 8 in the extension direction of the detection channel 3, so that the detection plate After receiving the squeezing force of the cardin 8, the detection plate 5 retracts along the direction of the sliding groove where it is located. Since the bottom of the detection plate 5 is provided with a spring 4, the detection plate 5 is always in contact with the side of the cardin 8 during the retraction process. The bottom of the detection plate 5 is provided with a distance sensor, which detects the moving distance of the detection plate 5. At the same time, the distance sensors in different directions perform detection at the same time. Several distance sensors are electrically connected to each other. Therefore, after the cardin 8 is inserted into the detection hole, the several distance sensors can detect the sizes of different positions on the circumference of the cardin 8 to avoid installation problems caused by size errors.

[0026] At the same time, the slider at the bottom of the detection base 2 is slidably arranged in the elliptical groove 9, and the position can be adjusted according to the actual produced wiring harness. When adjusted to the required position, the detection base 2 can be fixed by screws.

[0027] Since it is necessary to place the cardin 8 on the pressing surfaces of several detection plates 5 when detecting the size of the cardin 8, and it is difficult to control the depth of the cardin 8 inserted into the detection hole during detection, or the detection data may have a large error after the cardin 8 is skewed, in order to avoid this problem, in one embodiment, the detection plate 5 includes a long plate section and a short plate section, the long plate section is close to the outside of the detection channel 3, and the short plate section is close to the inside of the detection channel 3, and the short plate section is used for detection positioning of the cardin 8;

[0028] By dividing the detection plate 5 into two sections, and the two sections of the detection plate 5 have different sizes, during the insertion process of the cardin 8, the top of the cardin 8 continues to be inserted into the detection channel 3 after passing through the long board section until it reaches the short board section. At this time, the side of the cardin 8 abuts against the pressure surface of the short board section, and the bottom of the umbrella-shaped head of the cardin 8 abuts against the inner side surface of the long board section, forming a relatively stable state, which is convenient for the detection mechanism to detect the size of the umbrella-shaped head part of the cardin 8.

[0029] Due to the structure of the push-in assembly in the above-mentioned embodiment, after the cardin 8 is inserted into the detection hole for detection, since the bottom of the umbrella-shaped head of the cardin 8 abuts against the inner side of the long board section, it is difficult to pull out after the detection is completed. Forced pulling out may cause damage to the push-in assembly or the cardin 8. In order to avoid this problem, in one embodiment, the detection mechanism also includes a pull-out assembly, which includes a plurality of elastic rods 7 and a plurality of rollers 6. The bottom of the elastic rod 7 is arranged on the short board section, and the roller 6 is rotatably connected to the top of the elastic rod 7. The pull-out assembly swings in the abutting direction of the cardin 8, and the roller 6 is used to assist the pull-out of the cardin 8.

[0030] By changing the original parallel abutment between the bottom plane of the umbrella-shaped head of the kart 8 and the plane of the long board section to the abutment between the bottom plane of the umbrella-shaped head of the kart 8 and the rim surface of the roller 6, and since the roller 6 will produce relative rotation, after the bottom plane of the umbrella-shaped head abuts against the roller 6, since the kart 8 is generally made of rubber or soft plastic, the thinner part of the umbrella-shaped head will be deformed after being squeezed, so that the diameter of the umbrella-shaped head part will be reduced after deformation, and at the same time, it will slide out to the detection hole under the rolling action of the roller 6, avoiding damage to the kart 8 after being forcibly pulled out.

[0031] In one embodiment, one side of the detection plate 5 close to the outer side of the detection channel 3 is an arc surface. Through the arc surface mechanism outside the detection plate 5 and the inclination angle of the umbrella-shaped head part of the cardin 8, when the cardin 8 is squeezed into the detection hole, there is a force on the detection plate 5 along the sliding direction of the detection plate 5, so that the detection plate 5 slides after being squeezed, which facilitates the insertion detection of the cardin 8.

[0032] In one embodiment, one side of the detection plate 5 close to the inner side of the detection channel 3 is flat, and the inside of the detection plate 5 is flat. This is mainly because when the wiring harness is detected, multiple cardins 8 on the wiring harness need to be detected, and the wiring harness is easily pulled in this process. If the cardins 8 are not well limited, it is easy for one cardin 8 to be inserted into the detection hole while other cardins 8 inserted forward fall off. Therefore, by making the inner side of the detection plate 5 flat, the cardins 8 can be limited.

[0033] In one embodiment, a display component is further included, the display component includes a display light and a control module, the control module is electrically connected to the display light and a plurality of distance sensors respectively, and the display light displays different colors according to the size data acquired by the control module;

[0034] In order to know the test result after the test base 2 completes the test of the kart 8, the test data of the distance sensor is obtained through the control module, and the display light is displayed according to the output instruction of the control module. Different test results correspond to different colors of test lights. The staff judges whether the kart 8 is qualified according to the color of the test light.

[0035] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
