[0002] During the processing of automobile parts, in order to ensure the positioning quality of parts on the jig, a press clamp or a cylinder is usually used to press the parts. For example, Chinese Patent 202021427062.8 discloses a jig for pressing mechanisms of automobile headlight parts, including a jig body, a No. 1 transmission rod is provided on the upper part of one side of the jig body, a rotating mechanism is provided on one side of the No. 1 transmission rod, a vertical through hole is provided on the lower part of one side of the jig body, a pressing mechanism is provided in the vertical through hole, a return mechanism is provided on the other side of the jig body, an adjustment mechanism is provided on the upper end of the jig body, and a contact switch is provided through the middle of the jig body. Compared with the traditional pressing mechanism, it has a simpler structure and a smaller volume, and can be applied to more pressing scenarios. A contact switch is provided during the pressing process to detect whether each pressing operation is implemented, thereby avoiding the occurrence of leakage and non-pressing. In addition, after the pressing action is completed, the pressing mechanism automatically returns to its position, without the need for manual return, reducing manpower.

[0003] In existing vehicle parts positioning jigs, although the use of positioning parts such as press clamps can make the parts firmly positioned, it will interfere with the placement of the parts, making it inconvenient to position and release the parts, affecting the efficiency of part disassembly and replacement.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] See also Figure 1-2 The utility model provides a technical solution: a positioning device that is easy to disassemble, comprising:

[0029] A positioning substrate 1 is provided with a first positioning groove 11, and a part 9 is placed in the first positioning groove 11. A retaining edge 111 is provided outside the first positioning groove 11. A vent hole 112 is provided on the bottom surface of the first positioning groove 11. The vent hole 112 is connected to a negative pressure generating device through an air pipe. A second positioning groove 12 is also provided on one side of the first positioning groove 11.

[0030] The support block 2 is fixedly mounted on the positioning substrate 1 , and the component 9 is placed on the support block 2 . The width of the support block 2 is smaller than the width of the component 9 .

[0031] A plurality of notches 1111 are provided on the side wall of the enclosure edge 111 , which further facilitates robot or manual grasping of the parts 9 for unloading.

[0032] The support block 2 is also provided with a first positioning block 21 , which penetrates the part 9 to fully position the part 9 and prevent it from being separated from the support block 2 .

[0033] The first positioning block 21 is a rubber block. The first positioning block 21 is inserted and positioned with the component 9 by means of interference fit, thereby improving the positioning effect.

[0034] A second positioning block 113 is further disposed on the bottom surface of the first positioning groove 11 . The second positioning block 113 penetrates the part 9 to further position the part 9 to prevent position deviation when the part 9 is placed on the positioning substrate 1 .

[0035] The edge of the positioning substrate 1 is provided with a countersunk hole 114. The countersunk hole 114 is used to arrange bolts to fix the positioning substrate 1. The countersunk bolts are convenient for installing and removing the positioning substrate 1, and do not interfere with the positioning of the part 9.

[0036] Working principle: When the positioning device positions part 9, after part 9 is placed in the first positioning groove 11 of the contour design on the positioning substrate 1, the bending part of part 9 is positioned by the second positioning groove 12, and at the same time, the bending section at one end of part 9 is supported by the support block 2, and the other end is supported by the enclosure edge 111, so as to achieve the initial positioning of part 9. After that, the negative pressure generated by the negative pressure generating device makes part 9 adsorbed and positioned on the positioning substrate 1, so as to achieve full positioning of part 9 and facilitate processing. After the subsequent processing is completed, the negative pressure adsorption is released, and part 9 can be taken out upwards. The width of the support block 2 is smaller than that of the part 9, so that part 9 is easy to take and place, and part 9 does not need to be pressed down by positioning parts such as pressure clamps and cylinder pressure blocks to avoid interference and collision damage during positioning, which is convenient for disassembly and replacement, and improves the efficiency of part processing.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
