It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, the meanings of "several" and "multiple" are two or more, unless otherwise clearly and specifically defined.

[0024] As Figure 1-2 shown, a combined positioning jig includes a support assembly 10 and an adjustment assembly 20, where:

[0025] The support assembly 10 includes a base plate 1, more than one spacer plate 2 and more than one positioning plate 3. Each spacer plate 2 is detachably fixed to the upper end of a base plate 1 or another spacer plate 2, and each is provided with a first cavity 201 for avoiding the product 30 and penetrating the spacer plate 2. Each positioning plate 3 is detachably fixed to the upper end of a spacer plate 2 and is provided with a second cavity 301 adapted to the contour of the product 30 and penetrating the positioning plate 3. The outer contour projection of each second cavity 301 falls inside the outer contour projection of the first cavity 201 on the spacer plate 2 provided at its lower end;

[0026] The adjustment assembly 20 can be fitted in the first cavity 201 and / or the second cavity 302, and includes more than one adjustment plate 4. At least one end of several adjustment plates 4 is adapted to the first cavity 201 and / or the second cavity 301 and / or the upper end of the base plate 1.

[0027] In use, a spacer plate 2 is placed on the base plate 1 in a matching manner. If the longitudinal dimension of the product 30 is large, another spacer plate 2 can be stacked on the upper end of the spacer plate 2, and adjustment plates 4 can be filled in the first cavity 201 to adjust the total longitudinal depth formed by multiple first cavities 201. Then, a locking member is used to connect and fix the multiple spacer plates 2 to the base plate 1. Then, the product 30 is placed in the first cavity 201 so that its bottom touches the upper end of the base 1 and / or the adjustment plate 4 and / or the side wall of the first cavity 201. Finally, the positioning plate 3 is fixedly matched to the upper end of the spacer plate 2, and the product 30 is placed. The side wall of the relatively smaller second cavity 301 on the positioning plate 3 that matches the contour of the product 30 positions the product 30. Adjustment plates 4 can also be installed on the inner side wall of the second cavity 301 to fill the gap between the product 30 and the positioning plate 3, ensuring the abutment of the product 30 against the upper end of the base plate 1 and / or the second cavity 301 and / or the first cavity 201 and / or the adjustment plate 4, restricting its displacement in the vertical and horizontal planes, and achieving its positioning.

[0028] The utility model can adjust the longitudinal depth and transverse dimension of the cavity within a certain range by providing a detachably connected base plate 1, several spacer plates 2 and a cover plate 3, and providing several adjustment plates 4 that can be fitted in the cavities formed therebetween, so as to meet the use requirements of accommodating and positioning the same type of products with substantially the same contour but different versions. The overall structure of the jig is simple, the assembly is convenient, it can meet the production requirements of reducing costs during the product upgrade and replacement of production enterprises, improve the utilization rate of the jig, reduce costs and reduce material waste.

[0029] Specifically, as Figure 2 、 3As shown, a plurality of first positioning members 101 and second positioning members 102 are provided on the bottom plate 1 , and each of the first positioning members 101 passes through the bottom plate 1 .

[0030] Specifically, Figure 2 , 4 As shown, each pad 2 is provided with a plurality of third positioning members 202 and a fourth positioning member 203 , and the plurality of third positioning members 202 can be matched one by one with the plurality of second positioning members 102 , and each third positioning member 202 passes through each pad 2 .

[0031] Specifically, Figure 2 , 5 As shown, a plurality of fifth positioning members 302 are disposed on each positioning plate 3 , and the plurality of fifth positioning members 302 can be matched one by one with the plurality of fourth positioning members 203 , and each fifth positioning member 302 runs through each positioning plate 3 .

[0032] During assembly, the matching fifth positioning member 302 and the fourth positioning member 203 can fix the positioning plate 3 on the pad 2, the matching third positioning member 202 and the second positioning member 102 can fix the pad 2 on the base plate 1, and the first positioning member 101 can fix the base plate 1 on the support member, thereby achieving the fixation of the fixture.

[0033] Specifically, Figure 6 As shown, each adjustment plate 4 is a soft adjustment plate, or at least the end surface thereof in contact with the product 30 is covered with a soft anti-collision layer 401 .

[0034] It can be understood that the soft end surface of the adjustment plate 4 can prevent the corners of the product 30 from being damaged when it is loaded into the second cavity 301 and the first cavity 201. At the same time, when the product 30 is subjected to external forces during processing and production, such as asymmetric pressure caused by tightening screws, thrust generated by small accessories on the pressed product, etc., it can absorb and reduce the force between the product 30 and the fixture to protect the product 30.

[0035] Specifically, the bottom plate 1 is an aluminum plate, each pad 2 is a plug steel plate, and each positioning plate 3 is a polyurethane plate.

[0036] It can be understood that the plug steel is an engineering plastic with good dimensional stability, wear resistance, strength and self-lubrication. As a pad 2, it can better protect the product, while polyurethane has good plasticity and is not easy to deform, so it is easy to process the second cavity 301 that matches the special-shaped contour of the product, and the processing cost is low. At the same time, both the plug steel and polyurethane have excellent weather resistance and low water absorption, stable size, the fixture is not easy to deform, and the maintenance cost is low.

[0037] The above does not impose any limitation on the technical scope of the present utility model. Any modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
