[0023] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings. The terms used in the implementation part of the present application are only used to explain the specific embodiments of the present application, rather than aiming to limit the present application.

[0024] Refer to Figures 1 to 7 , the embodiment of the present application provides an installation and positioning device for a wiring harness bracket 7 of an electric box cover 8, including a positioning tooling and a glue dispenser 6 for applying glue to two feet of the wiring harness bracket 7.

[0025] The positioning tooling includes a bottom plate 1, a plurality of limit frames 2 fixedly installed on the bottom plate 1, and a plurality of positioning units. A limit groove is provided in the middle of the limit frame 2 for accommodating the limit unit.

[0026] The positioning unit includes a positioning block 3. A placing plane 31 for flatly placing on the battery box cover is provided on the upper part of the positioning block 3; a bracket positioning groove 32 for accommodating and positioning the wiring harness bracket 7 is provided on the positioning block 3. The bracket positioning groove 32 opens to the side of the placing plane 31. A magnetic attraction part 4 for attracting the wiring harness bracket 7 is fixedly arranged in the bracket positioning groove 32. The wiring harness bracket 7 is made of a ferromagnetic material that can be attracted by the magnetic attraction part 4. Two or more positioning pins 5 for respectively forming a pin hole fit with the hole positions 81 of the electric box cover 8 are also fixedly arranged on the placing plane 31.

[0027] Among them, the bracket positioning groove 32 can ensure the accuracy of the position between the wiring harness bracket 7 and the positioning block 3, and the magnetic attraction part 4 can attract the wiring harness bracket 7. In this way, when the positioning block 3 is buckled onto the electric box cover 8, the wiring harness bracket 7 can be prevented from falling off, and positioning is carried out with reference to the hole positions 81 of the electric box cover 8 through the positioning pins 5, improving the installation position accuracy of the wiring harness bracket 7.

[0028] In some embodiments, a protruding portion 33 protruding upward is integrally connected to the positioning block 3, and an arc-shaped side surface 331 that cooperates with and touches the arc chamfer position of the electric box cover 8 is formed on the side of the protruding portion 33. The protruding portion 33 is a structure for error correction and can prevent the positioning pin 5 from cooperating with other hole positions 81.

[0029] In some embodiments, a pin slot 34 for installing the positioning pin 5 is provided on the positioning block 3, and the pin slot 34 and the positioning block 3 are locked by screws.

[0030] In some embodiments, a magnetic attraction slot for installing the magnetic attraction member 4 is provided in the middle of the bottom of the bracket positioning slot 32, and the magnetic attraction member 4 and the positioning block 3 are also fastened by screws. The screw connection has a simple structure and is convenient for disassembly and assembly. The magnetic attraction member 4 and the positioning block 3 can also be bonded by glue.

[0031] In some embodiments, a first seat body 36 and two second seat bodies 37 respectively arranged on the left and right sides of the first seat body 36 are integrally connected to the positioning block 3. The upper surface of the second seat body 37 is the placement plane 31. The bracket positioning slot 32 is formed on the upper surface of the first seat body 36. The upper surface of the first seat body 36 is lower than the placement plane 31, so that the two feet of the wire harness bracket 7 are flush with the placement plane 31. A concave space 38 for separating the two is formed between the first seat body 36 and the second seat body 37. The concave space 38 is mainly used to avoid the positions of the two feet of the wire harness bracket 7.

[0032] The working process and usage method of the above-described embodiment of the installation and positioning tooling for the wire harness bracket 7 of the electric box cover 8 are briefly described as follows:

[0033] Place each positioning unit in the positioning frame to ensure the accuracy of the positioning unit's position, so that the dispensing machine 6 can accurately apply glue to the wire harness bracket 7. Place the wire harness bracket 7 into the bracket positioning slot 32 of the positioning block 3 and be attracted by the magnetic attraction member 4. Start the dispensing machine 6 to apply glue to the two feet of the wire harness bracket 7. Move the positioning block 3 onto the electric box cover 8, invert the positioning block 3, and perform positioning through the two positioning pins 5 and the two hole positions 81 of the electric box cover 8. The protruding portion 33 touches the chamfer position of the electric box cover 8 to ensure that the wire harness bracket 7 can be bonded at the corresponding position. It is best to pull out the positioning block 3 and then put the positioning block 3 back into the limit frame 2.
