Description

Technical Field

[0001] This utility model relates to the field of sandblasting equipment for irregularly shaped products, and in particular to a sandblasting fixture that can be automatically flipped. Background Technology

[0002] Sandblasting is a surface treatment process for workpieces. Powered by compressed air, it propels abrasive materials (copper ore sand, quartz sand, corundum, iron sand, sea sand) at high speed onto the surface of the workpiece, altering its appearance or shape. Due to the impact and cutting action of the abrasive on the workpiece surface, it achieves a certain degree of cleanliness and varying roughness, improving its mechanical properties. This enhances the workpiece's fatigue resistance, increases adhesion between the workpiece and coatings, extends coating durability, and also facilitates coating leveling and decoration.

[0003] Existing designs, such as Chinese Patent 202421478642.8, can only achieve sandblasting on one side. For an irregularly shaped part, it is not suitable for double-sided sandblasting. Moreover, the irregularly shaped surface needs to be sandblasted, and the area is relatively large. Therefore, existing designs generally use face-to-face sandblasting to achieve stable positioning. Utility Model Content

[0004] The main purpose of this invention is to propose an automatically flipping sandblasting fixture, which aims to achieve double-sided sandblasting of non-standard products and improve processing efficiency.

[0005] To achieve the above objectives, this utility model proposes an automatically flipping sandblasting fixture, comprising an upper plate and a lower plate.

[0006] The upper plate and the lower plate form a through-hole positioning groove, the positioning groove is distributed in an array, and the positioning groove is used to place the product.

[0007] The front wall of the positioning groove is a first vertical wall. The upper plate and the lower plate each have arc-shaped stops extending outward from both sides of the first vertical wall. The rear ends of the two arc-shaped stops are provided with side stops, which are arranged opposite to the first vertical wall.

[0008] The first vertical wall, the arc-shaped baffle, and the side baffle form a sandblasting channel.

[0009] In the actual design, the first vertical wall abuts against the end face of the product, and the product is positioned using the arc-shaped stop and side stop of the contour structure.

[0010] The reason why existing products cannot achieve double-sided sandblasting is that a profile block needs to be installed on the first vertical wall to extend into the groove of the product for restraint, thus creating a limitation.

[0011] The additional curved and side baffles can shield non-blasted surfaces, effectively improving blasting efficiency.

[0012] The existing sandblasting process involves placing the product in a fixture, sandblasting the first side, removing the product, and sandblasting the second side. This process is generally completed within a single fixture, which is therefore inefficient. Attached Figure Description

[0026] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0027] It should be noted that if any directional indication (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.) is involved in the embodiments of this utility model, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0028] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.

[0029] like Figures 1 to 5 As shown, an automatically flipping sandblasting fixture includes an upper plate 11 and a lower plate 12.

[0030] The upper plate 11 and the lower plate 12 form a through-hole positioning groove 10, the positioning groove 10 is distributed in an array, and the positioning groove 10 is used to place the product 100;

[0031] The front wall of the positioning groove 10 is a first vertical wall 21. The upper plate 11 and the lower plate 12 extend outward from both sides of the first vertical wall 21 with arc-shaped stops 31. The rear ends of the two arc-shaped stops 31 are provided with side stops 32, which are arranged opposite to the first vertical wall 21.

[0032] The first vertical wall 21, the arc-shaped baffle 31 and the side baffle 32 form a sandblasting channel 3.

[0033] In the actual design, the first vertical wall 21 abuts against the end face of the product 100, and the product 100 is positioned by the arc-shaped stop 31 and the side stop 32 of the contour structure.

[0034] The reason why the existing product 100 cannot achieve double-sided sandblasting is that a profile block needs to be installed on the first vertical wall 21 to extend into the groove of the product 100 for limitation, thus creating a limitation.

[0035] The additional arc-shaped baffle 31 and side baffle 32 can shield the non-blasted surface, effectively improving the blasting efficiency.

[0036] The existing sandblasting process involves placing the product 100 in a fixture, sandblasting the first side, disassembling, and sandblasting the second side. This is generally completed within a single fixture, which is therefore inefficient.

[0037] Specifically, the upper plate 11 and the lower plate 12 are attached to each other in a detachable manner.

[0038] In this embodiment of the utility model, the detachable method is magnetic attraction, snap-on, or quick-release screw, preferably magnetic attraction, which facilitates quick assembly and disassembly.

[0039] Specifically, the arc-shaped stop 31 is gradually lowered from the outside to the inside to form a contour limit, thereby conforming to the arc-shaped appearance of the product 100.

[0040] In this embodiment of the invention, the wall surface opposite to the first vertical wall 21 is the second vertical wall 22.

[0041] The positioning groove 10 is configured to gradually narrow from the first vertical wall 21 toward the second vertical wall 22.

[0042] Specifically, a mating line 4 is provided between the upper plate 11 and the upper plate 11, and the positioning groove 10 is symmetrically arranged with respect to the mating line 4.

[0043] In this embodiment of the utility model, a through hole 5 is provided at the connecting end between the arc-shaped stop 31 and the side stop 32 on one side, and the through hole 5 is used for the position of the product 100 that needs to be sandblasted.

[0044] Specifically, there are two through holes 5.

[0045] In this embodiment of the invention, the upper positions of the arc-shaped baffle 31 and the side baffle 32 together with the upper plate 11 or the lower plate 12 form a clearance groove 6. The clearance groove 6 facilitates direct sandblasting and avoids the problem of sandblasting resistance caused by large thickness, which could lead to incomplete processing of the mating surface to be sandblasted.

[0046] Specifically, the width of one side of the arc-shaped stop 31 is smaller than the width of the other side of the arc-shaped stop 31.

[0047] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
