Description

Technical Field

[0001] The utility model relates to the technical field of positioning jigs, in particular to a combined graphite jig. Background Art

[0002] Graphite jigs have excellent thermal stability, good corrosion resistance, and wear resistance, and are easy to process. They are widely used in the electronics and semiconductor industries, aerospace, automotive and shipbuilding, medical equipment, and other fields. Currently, most graphite jigs are custom-made, with high design and manufacturing costs. Graphite jigs are also relatively easy to break and scratch, and require careful handling and avoidance of collisions during use and storage. This leads to high usage and maintenance costs, making the cost of using graphite jigs high. On the other hand, with the accelerating pace of product version upgrades, the frequency of use of specialized jigs has further decreased, and the cost of the jigs added to the products has also increased. Utility Model Content

[0003] In response to the problems existing in the above-mentioned prior art, the utility model provides a combined graphite fixture that can position different versions of a product or products with similar structures, reduce the design and manufacturing costs of the fixture, shorten the production cycle of the fixture, and improve the utilization rate of the fixture, thereby achieving the purpose of reducing production sharing costs.

[0004] In order to solve the above technical problems, a technical solution adopted by the present invention is as follows:

[0005] A combined graphite jig comprises a jig body, the jig body being provided with a positioning structure adapted to the contour of a product; the jig body being further detachably provided with one or more adsorption positioning blocks, each of which is embedded in the jig body, the contour of its upper end being adapted to the product, each of which is provided with a first air channel, the jig body being provided with a second air channel connected to each of the first air channels, and the second air channel being connected to an air pump via a pipeline.

[0006] As a further elaboration of the above technical solution:

[0007] In the above technical solution, the fixture body is provided with a plurality of positioning slots that are adapted one by one with the adsorption positioning blocks, and each of the positioning slots is provided with one or more first ventilation slots and second ventilation slots connected thereto, and one end of each of the first ventilation slots extends to the upper end of the fixture body, and each of the second ventilation slots and / or positioning protrusions.

[0008] In the above technical solution, each of the first air channels includes several air grooves and through holes, several of the air grooves are arranged at the upper end of the adsorption positioning block and are interconnected, and each of the through holes is arranged on an air groove and extends to the bottom end of the adsorption positioning block.

[0009] Compared with the existing technology, the beneficial effect of the present invention is that by setting the graphite jig as a structure composed of a detachable jig body and an adsorption positioning block, only the adsorption positioning block needs to be replaced to meet the positioning needs of different versions of products or products with similar structures, thereby reducing the design and manufacturing costs of the jig, shortening the production cycle of the jig, and improving the utilization rate of the jig, thereby achieving the purpose of reducing the production sharing cost.

[0015] For ease of understanding, Figure 1 A structural schematic diagram of two versions of the product applicable to this embodiment is shown. It can be seen that the difference between the two versions lies only in the shape of one positioning surface. If a fixture is customized for each version of the product, the fixture manufacturing cycle will be long, the cost will be high, and the utilization rate of each fixture will be low.

[0016] like Figure 2As shown, a combined graphite jig includes a jig body 10, on which is provided a positioning structure 11 adapted to the contour of the product; the jig body 10 is also detachably fixed with one or more adsorption positioning blocks 20, each of which is embedded in the jig body 10, and the contour of its upper end is adapted to the product, each of which is provided with a first air channel 21, and the jig body 10 is provided with a second air channel 12 connected to each first air channel 21, and the second air channel 12 is connected to the air pump through a pipeline.

[0017] During use, the adsorption positioning blocks 20 are snapped into the jig body 10 one by one. After assembly is in place, the product is aligned with the positioning structure 11 and placed on the jig body 10. The air pump is then started to pump air. The gas between the product and the jig body 10 and the adsorption positioning blocks 20 is extracted through the first air channel 21 and the second air channel 12, thereby firmly adsorbing and fixing the product on the jig body 10 and the adsorption positioning blocks 20. When the structure of the product changes, only the corresponding adsorption positioning blocks 20 need to be replaced.

[0018] In some embodiments of the present invention, a plurality of positioning slots 13 are provided on the jig body 10, which are matched one by one with the adsorption positioning blocks 20. Each positioning slot 13 is provided with one or more first vent slots 14 and second vent slots 15 connected thereto on the side thereof. One end of each first vent slot 14 extends to the upper end of the jig body 10, and an open end of each second vent slot 15 is provided at the bottom of a positioning slot 13, and the other open end passes through the jig body 10 and extends to its bottom or side wall.

[0019] It can be understood that in order to avoid the difficulty in removing the adsorption positioning block 20 due to the formation of vacuum between the adsorption positioning block 20 and the fixture body 10, the first vent slot 14 and the second vent slot 15 can connect the cavity where each adsorption positioning block 20 is located, that is, the positioning slot 13, with the outside world to facilitate disassembly and assembly operations; at the same time, the first vent slot 14 extending to the upper end of the fixture body 10 also reserves operating space for the clamping fixture for clamping the adsorption positioning block 20.

[0020] In some embodiments of the present invention, a plurality of adsorption positioning blocks 20 are further provided with positioning holes 22a and / or positioning protrusions 22b adapted to the product.

[0021] In the above embodiment, each first air channel 21 includes a plurality of air grooves 1 and through holes 2, and the plurality of air grooves 1 are arranged at the upper end of the adsorption positioning block 20 and are interconnected, and each through hole 2 is arranged on an air groove 1 and extends to the bottom end of the adsorption positioning block 20.

[0022] The utility model provides a graphite jig with a structure composed of a detachable jig body 10 and an adsorption positioning block 20. Only the adsorption positioning block 20 needs to be replaced to meet the positioning needs of different versions of products or products with similar structures. This reduces the design and manufacturing costs of the jig, shortens the production cycle of the jig, and improves the utilization rate of the jig, thereby achieving the purpose of reducing the production sharing cost.

[0023] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
