Description

Technical Field

[0001] This utility model relates to the field of surface treatment technology, specifically to a rapid sandblasting masking fixture. Background Technology

[0002] In the surface treatment process of precision parts, sandblasting is a key process to improve the adhesion, aesthetics and functionality of the workpiece surface. For parts with complex irregular structures, especially those with grooves, hollows or abrupt curves, it is necessary to accurately mask the non-sandblasted areas to avoid abrasive or coating erosion of non-target areas. Therefore, a rapid sandblasting masking fixture is needed to solve the above-mentioned problems. Utility Model Content

[0003] The purpose of this utility model is to solve any of the problems in the above-mentioned technologies, thereby proposing a rapid sandblasting masking fixture, including a rotary clamping working system and a rapid sandblasting masking system. The rotary clamping working system has a rotary worktable at its bottom, and three fixed slide rails with equal spacing are provided on the rotary worktable. The fixed slide rails are fixedly connected to the rotary worktable. Fixed sliders are provided inside the three fixed slide rails. The fixed sliders are slidably connected to the fixed slide rails. A product placement fixture is placed above the fixed sliders. The product placement fixture is fixedly connected to the fixed sliders by two nuts.

[0004] Furthermore, the rapid sandblasting masking system includes masking tape, a circular part, a contour masking fixture, and masking tape on the outer side of the circular part. The masking tape is positioned above three product placement fixtures and is movably connected to the product placement fixtures. A circular part is positioned above the masking tape and is movably connected to the masking tape. A contour masking fixture is positioned on the circular part and is movably connected to the circular part. A masking tape on the outer side of the circular part is positioned on the outer side of the circular part and is movably connected to the circular part.

[0005] Furthermore, the circular part includes an inner sandblasted surface, an outer masking surface, and a groove area. The inner side of the circular part is configured as the inner sandblasted surface, and the outer side is configured as the outer masking surface. An outer masking tape is provided on the outer side of the outer masking surface. The outer masking surface and the outer masking tape are fixedly connected. A groove area in the shape of a circular array is provided above the circular part. The groove area is slidably connected to a contour masking fixture.

[0006] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0007] 1. This utility model, through the precise fit between the contour-following masking fixture and the groove area of ​​the part, can automatically fit the complex groove contour, completely eliminating the wrinkles and gaps caused by traditional tape masking, effectively preventing sandblasting media from penetrating into non-target areas, and significantly improving product yield.

[0008] 2. This utility model adopts a modular masking system design, which combines the precise coverage of the groove by the contour jig with the rapid masking of the flat area by the tape. This not only simplifies the operation process, but also, through the adjustment mechanism of the slider and the replaceability of the jig, can flexibly adapt to the processing needs of irregular parts with different sizes and groove layouts, effectively reducing the production line switching cost.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of the present invention.

[0018] The following describes a rapid sandblasting masking fixture according to an embodiment of the present invention, with reference to the accompanying drawings. Figures 1 to 5 As shown, a rapid sandblasting masking fixture includes a rotary clamping working system 1 and a rapid sandblasting masking system 2. The rotary clamping working system 1 has a rotary worktable 101 at its bottom. The rotary worktable 101 has three fixed slide rails 102 with equal spacing. The fixed slide rails 102 are fixedly connected to the rotary worktable 101. The three fixed slide rails 102 have fixed sliders 103 inside them. The fixed sliders 103 are slidably connected to the fixed slide rails 102. A product placement fixture 105 is placed above the fixed sliders 103. The product placement fixture 105 is fixedly connected to the fixed sliders 103 by two nuts 104.

[0019] Preferably, the rapid sandblasting masking system 2 includes masking tape 201, a circular part 202, a contour masking fixture 203, and masking tape 204 on the outer side of the circular part. The masking tape 201 is disposed above three product placement fixtures 105 and is movably connected to the product placement fixtures 105. The circular part 202 is disposed above the masking tape 201 and is movably connected to the masking tape 201. The contour masking fixture 203 is disposed on the circular part 202 and is movably connected to the circular part 202. The outer side of the circular part 202 is provided with masking tape 204 and is movably connected to the circular part 202.

[0020] In a specific embodiment: the operator places the circular part 202 to be processed on the product placement fixture 105 and fixes it so that the outer shielding surface 2002 of the part contacts the shielding tape 201. Then, the operator slides the fixed slider 103 along the fixed slide rail 102 and adjusts it until the center of the part is aligned with the axis of the rotary table 101. Then, the operator locks it with the nut 104. Next, the contour shielding fixture 203 is embedded into the groove area 2003 of the circular part. The sliding connection structure between the two automatically fits the groove contour. Finally, the outer shielding tape 204 of the circular part is pasted on the outer shielding surface 2002 of the part. After the rotary table 101 is started, the three stations are switched in a cycle: the first station loads the part, the second station performs sandblasting, and the third station disassembles the processed part to achieve continuous batch operation.

[0021] Preferably, the circular part 202 includes an inner sandblasted surface 2001, an outer shielding surface 2002, and a groove area 2003. The inner side of the circular part 202 is configured as the inner sandblasted surface 2001, and the outer side of the circular part 202 is configured as the outer shielding surface 2002. An outer shielding tape 204 is provided on the outer side of the outer shielding surface 2002. The outer shielding surface 2002 and the outer shielding tape 204 are fixedly connected. A groove area 2003 in a circular array is provided above the circular part 202. The groove area 2003 is slidably connected to the contour shielding fixture 203.

[0022] In a specific embodiment: For irregularly shaped parts with circular array groove areas 2003, the operator first replaces the matching contour masking fixture 203, fixes the part to the product placement fixture 105, and then pushes the contour masking fixture 203 to slide along the groove area 2003 of the circular part, so that its curved surface completely fills the groove. The gap between the groove area 2003 and the contour masking fixture 203 is extremely small, requiring no additional sealing. Subsequently, masking tape 204 is pasted on the outer masking surface 2002 of the circular part. During sandblasting, the abrasive only acts on the inner sandblasting surface 2001 of the circular part, and the inner wall of the groove is protected by the contour masking fixture 203. After processing, the rotary table 101 moves to the next station, and new parts are clamped simultaneously. When changing to different contour masking fixtures 203, the production line changeover time is significantly shortened.

[0023] Working Principle: The working principle of this utility model is to achieve multi-station cyclic operation through the rotary clamping system 1, while using the rapid sandblasting masking system 2 to accurately mask irregularly shaped grooves. The operator first places the circular part 202 on the product placement fixture 105, slides the fixed slider 103 along the fixed slide rail 102 to adjust the position, and locks it in place with two nuts 104. Then, the contour masking fixture 203 is embedded into the groove area 2003 of the circular part. The sliding connection structure makes the curved surface of the fixture 203 tightly fill the groove, and then the circular part is covered with a masking fixture. Side shielding surface 2002 is covered with shielding tape 204 covering the outer side of the circular part. After startup, the rotating worktable 101 drives the three stations to rotate periodically. The first station performs part loading and shielding operations, the second station performs sandblasting on the exposed inner sandblasting surface 2001 of the circular part, and the third station disassembles the processed part. During the sandblasting process, the contour shielding fixture 203 prevents abrasive from entering the groove area 2003, and the tape 204 protects the outer shielding surface 2002. The rotating clamping system realizes the parallel operation of the three processes, which greatly improves the efficiency of continuous operation.
