Abstract
Description
Technical Field
[0001] This utility model belongs to the field of spraying technology, and specifically relates to a spraying fixture. Background Technology
[0002] For parts painting processes, the parts generally need to be fixed in a painting fixture to facilitate painting. In existing technologies, the surfaces of the parts that come into contact with the painting fixture after painting will have many burrs, requiring an additional deburring process to remove them. Utility Model Content
[0003] The purpose of this invention is to provide a spraying fixture that solves the problem in related technologies where many burrs appear on the surface of parts that come into contact with the spraying fixture after spraying.
[0004] Therefore, this utility model provides a spraying fixture, including: a base and an insert block, the insert block being disposed on the top of the base, the base being provided with a groove, and the insert block being fitted into the part to be sprayed.
[0005] Preferably, the embedded block and the base are integrally formed.
[0006] Preferably, the base and the insert are made of silicone.
[0007] Preferably, the groove surrounds the inlay.
[0008] Preferably, the shape of the embedded block is one of the following: circle, ellipse, triangle, rectangle, and polygon.
[0009] Preferably, after the insert is fitted into the part to be coated, there is a gap between the base and the part to be coated.
[0010] Preferably, the width of the gap is in the range of 0.5-2mm.
[0011] Preferably, the groove is located below the part to be coated.
[0012] Preferably, the ratio of the width of the groove to the diameter of the base is in the range of 1:10 to 1:20.
[0013] Preferably, the ratio of the depth to the width of the trench is in the range of 1:1 to 1:3.
[0014] Beneficial effects:
[0015] 1. This utility model provides a spraying fixture, which fixes the part to be sprayed by fitting an inner block into the part to be sprayed. A gap is left between the part to be sprayed and the base. The groove allows air to return in the gap during spraying, thereby spraying to form a smooth part surface without the need for deburring. Attached Figure Description
[0016] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.
[0017] Figure 1 This is a schematic diagram of the structure of an embodiment 1 of the spraying fixture provided by this utility model.
[0018] Figure 2 This is a schematic diagram of the spraying state of Embodiment 1 of a spraying fixture provided by this utility model.
[0019] In the diagram, 1-base, 2-embedded block, 3-groove, 4-part to be painted. Detailed Implementation
[0020] The following detailed description of preferred embodiments of the present invention, along with the included examples, will make the content of the present invention more readily understood. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. In case of any conflict, the definitions in this specification shall prevail.
[0021] Example 1:
[0022] Provided such as Figure 1-2 The spraying fixture shown includes: a base 1 and an insert block 2, the insert block 2 being disposed on the top of the base 1, the base 1 having a groove 3, and the insert block 2 fitting into the part 4 to be sprayed. The insert block 2 and the base 1 are integrally formed. The base 1 and the insert block 2 are made of silicone. The groove 3 surrounds the insert block 2.
[0023] Existing spraying fixtures are generally made of aluminum alloy, which can easily damage the parts to be sprayed 4 during the spraying process. The base 1, made of silicone material and molded in one piece, is soft and will not damage the parts to be sprayed 4 during contact.
[0024] The shape of the embedded block 2 can be one of the following: circular, elliptical, triangular, rectangular, or polygonal. The shape of the embedded block 2 can be specifically set according to the shape of the part 4 to be painted. In this embodiment, the part 4 to be painted is annular, and the shape of the embedded block 2 is circular, which is one feasible approach.
[0025] After the insert 2 is fitted into the part 4 to be painted, there is a gap between the base 1 and the part 4. The width of the gap ranges from 0.5 to 2 mm. The groove 3 is located below the part 4. The ratio of the width of the groove 3 to the diameter of the base 1 ranges from 1:10 to 1:20. The ratio of the depth of the groove 3 to its width ranges from 1:1 to 1:3. The gap between the part 4 and the base 1 allows air to return within the gap during painting through the groove 3, resulting in a smooth surface on the part without the need for deburring.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
