[0035] The following will describe in detail some embodiments of this application with reference to the drawings. Without conflict, those skilled in the art can combine and combine the different embodiments or examples represented in this application and the features of different embodiments or examples.
[0036] The embodiments of this application disclose a positioning fixture. Referring to Figure 2 , the positioning fixture includes a base 1, a support block 2, and a receiving plate 3. The base 1 serves as a support carrier and is fixedly installed on the workbench; the support block 2 is movably arranged on the base 1, and the receiving plate 3 is installed on the support block 2. Wherein, a V-shaped groove 4 is formed on the receiving plate 3, and the V-shaped groove 4 is used for placing parts.
[0037] Combined with Figure 3 , when drilling a part is required, first, the staff places the part in the V-shaped groove 4 so that the outer surface of the part can be tangent to the receiving plate 3, thereby restricting the part from rotating along its own circumferential direction. Then, the staff presses the part by hand, and then controls the drilling machine to drill on the surface of the part. During the drilling process, the part is subjected to the static friction force of the receiving plate 3, and the position of the part is not easily shifted, realizing a reduction in the possibility of the part falling during the processing and improving the processing efficiency and accuracy.
[0038] Among them, a cushion block 5 is also fixedly connected to the bottom of the support block 2. The cushion block 5 is made of a non-slip material and is in close contact with the base 1. The non-slip material has a large coefficient of friction, which can increase the static friction between the cushion block 5 and the base 1, reduce the possibility of the support block 2 moving, and improve the accuracy of the position of the part during drilling.
[0039] Specifically, an anti-slip layer (not shown in the figure) is also provided on the receiving plate 3. The anti-slip layer is located in the V-shaped groove 4 and is made of a polymer material such as rubber or polyvinyl chloride. The anti-slip layer can increase the static friction between the part and the receiving plate 3, and further reduce the possibility of the part rotating during drilling. Refer to Figure 4 , one end of the receiving plate 3 is also fixedly connected with a positioning post 6. The positioning post 6 is horizontally arranged and is located in the V-shaped groove 4. The positioning post 6 is used for one end of the part to be inserted, so as to realize the pre-positioning of the part and improve the stability of the part during drilling.
[0040] In some embodiments, the receiving plate 3 is detachably connected to the support block 2. A plug 7 is fixedly connected to the bottom of the receiving plate 3, and a slot 8 corresponding to the position of the plug 7 is provided on the support block 2. The plug 7 is inserted into the slot 8. When positioning parts of different sizes, the receiving plate 3 with a corresponding size of V-shaped groove 4 can be replaced for positioning, improving the practicability. In addition, a plug pin 9 is also detachably connected to the support block 2. The plug pin 9 is inserted into both the plug 7 and the support block 2 at the same time, restricting the plug 7 from disengaging from the slot 8, improving the connection stability between the receiving plate 3 and the support block 2, and not interfering with the disassembly of the receiving plate 3 at the same time.
[0041] According to some embodiments of the present application, optionally, please refer to Figure 4 . A fixing block 10 is also fixedly connected to the base 1. The support block 2 and the fixing block 10 are connected by a hinge plate 11. One end of the hinge plate 11 is rotatably connected to the support block 2, and the rotation axis of the hinge plate 11 is in the vertical direction, so that the hinge plate 11 can rotate in the horizontal plane. The other end of the hinge plate 11 is locked to the fixing block 10 through a fastener 12. The fastener 12 is a fastening bolt, and the fastening bolt passes through the hinge plate 11 and is screwed onto the fixing block 10.
[0042] The staff can reasonably adjust the position of the support block 2 according to actual needs, thereby changing the relative position between the receiving plate 3 and the drilling machine. After adjustment, the staff appropriately rotates the hinge plate 11 to place the hinge plate 11 on the fixing block 10, and then locks the hinge plate 11 to the fixing block 10 with a fastening bolt to restrict the movement of the support block 2. At the same time, the fastening bolt will also exert a downward pressure on the support block 2, further reducing the possibility of the position of the receiving plate 3 shifting.
[0043] In addition, a universal joint flexible pipe 13 is also connected to the base 1. The universal joint flexible pipe 13 is close to the receiving plate 3 and is connected to an external air pump. The universal joint flexible pipe 13 is used to blow off the waste materials in the V-shaped groove 4. During the drilling process, debris will be generated, and the debris will remain in the V-shaped groove 4, resulting in the surface of the part being easily adhered with debris, which affects the product quality. By adding the universal joint flexible pipe 13, the staff can use the universal joint flexible pipe 13 to blow off the waste materials in the V-shaped groove 4, improving the cleanliness of the surface of the receiving plate 3.
[0044] The implementation principle of a positioning fixture according to an embodiment of the present application is as follows: When drilling a part is required, first, the staff places the part in the V-shaped groove 4 so that the outer surface of the part can be tangent to the receiving plate 3, thereby restricting the part from rotating along its own circumferential direction. Then, the staff clips one end of the part on the positioning post 6 and presses the part by hand, and then controls the drilling machine to drill on the surface of the part. During the drilling process, the part is under the action of the static friction force of the receiving plate 3, and the position of the part is not easily shifted, realizing the reduction of the possibility of the part falling during the processing and improving the processing efficiency and accuracy.
[0045] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
