Description

Technical Field

[0001] This utility model relates to the field of sandblasting treatment technology for parts surface, and in particular to a general-purpose sandblasting tool for parts. Background Technology

[0002] In existing material handling and processing, pallet-type tooling is often used to place, transport, and transfer bulk materials, granular products, or sheet-like workpieces. Traditional pallets mostly use a single-layer structure, providing only basic support. During use, workpieces are primarily placed manually, and simple positioning is achieved through the limited areas on the pallet surface. However, when handling products with powder residue or prone to dust accumulation, problems such as low efficiency, poor sand flow, poor positioning accuracy, and excessive pallet weight often arise.

[0003] Most material pallets typically use a single-layer flat structure, which lacks effective sand leakage channels. Powder or fine particles often accumulate on the pallet surface, making it difficult to keep the bottom surface of the workpiece clean and stable during processing due to sand blockage. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a universal sandblasting fixture for parts, which aims to improve the problem in the prior art that it is difficult to keep the bottom surface of the workpiece clean and stable due to sand accumulation and blockage.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A general-purpose sandblasting fixture for parts includes a first base plate, a pin post inside the first base plate, multiple sets of sand leakage and anti-cavity grooves inside the first base plate, multiple sets of large-diameter weight reduction holes and small-diameter weight reduction holes inside the first base plate, an exhaust hole inside the first base plate, and a limit frame outside the pin post, the limit frame being attached to the upper surface of the first base plate.

[0007] By adopting the above technical solution, sand flows out from the through channel through the first and second sand leakage channels, thereby avoiding the effect of sand accumulation.

[0008] Preferably, the limiting frame has multiple sets of material grooves inside, multiple sets of small-diameter weight reduction holes and large-diameter weight reduction holes inside, and multiple sets of exhaust holes inside.

[0009] Preferably, the exterior of the second small-diameter weight-reducing hole corresponds one-to-one with the exterior of the first small-diameter weight-reducing hole, the exterior of the second large-diameter weight-reducing hole corresponds one-to-one with the exterior of the first large-diameter weight-reducing hole, and the exterior of the second exhaust hole corresponds one-to-one with the exterior of the first exhaust hole.

[0010] Preferably, the pin post is provided with a second base plate on its exterior, and the interior of the second base plate is provided with multiple sets of sand leakage and anti-cavity grooves. The exterior of the second base plate is attached to the upper surface of the limiting frame.

[0011] Preferably, the interior of the second base plate has multiple sets of small-diameter weight-reduction holes and multiple sets of large-diameter weight-reduction holes, and the exterior of the second base plate has multiple sets of exhaust holes.

[0012] Preferably, the exterior of the small-diameter weight-reducing hole three corresponds one-to-one with the exterior of the small-diameter weight-reducing hole two, the exterior of the large-diameter weight-reducing hole three corresponds one-to-one with the exterior of the large-diameter weight-reducing hole two, and the exterior of the exhaust hole three corresponds one-to-one with the exterior of the exhaust hole two.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the sand leakage and void-avoidance groove one and sand leakage and void-avoidance groove two inside the first base plate and the second base plate make it easy for the fixture to flow out from the through groove during the sandblasting process, thereby avoiding the effect of sand accumulation, and thus improving the problem in the prior art that it is difficult to keep the bottom surface of the workpiece clean and stable due to sand accumulation and blockage.

[0015] 2. In this utility model, the first base plate, the limiting frame, and the second base plate are fixed by the pin column, which facilitates the fitting of the frame and the base plate, thereby effectively preventing displacement or misalignment between the two and ensuring the stability of the tooling.

[0022] 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 some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Example 1

[0024] Reference Figures 1-3 An embodiment of this utility model is provided: a general-purpose parts sandblasting fixture, including a first base plate 1, a pin post 2 is provided inside the first base plate 1, multiple sets of sand leakage and anti-cavity grooves 4 are opened inside the first base plate 1, multiple sets of large-diameter weight reduction holes 5 and small-diameter weight reduction holes 6 are opened inside the first base plate 1, an exhaust hole 14 is opened inside the first base plate 1, and a limit frame 3 is provided outside the pin post 2, with the outside of the limit frame 3 attached to the upper surface of the first base plate 1.

[0025] Specifically, the first base plate 1 is used to connect the limiting frame 3, and the first base plate 1 is provided with 12 small-diameter weight-reducing holes corresponding to the slot positions in the limiting frame 3. The sand leakage and air-avoiding groove 4 allows sand to flow through the grooves during the sandblasting process, avoiding sand accumulation. The pin column 2 is used to install the limiting frame 3. The limiting frame 3 is used to reasonably separate the products so that they will not move and interfere during movement. The large-diameter weight-reducing hole 5 is used to reduce the overall weight of the first base plate 1, and the small-diameter weight-reducing hole 6 is used to reduce the overall weight of the first base plate 1. The vent hole 14 is used for ventilation to prevent air stagnation during bonding, thereby avoiding the effect of sand accumulation. This improves the problem in the prior art where it is difficult to keep the bottom surface of the workpiece clean and stable due to sand accumulation and blockage.

[0026] Reference Figure 3 and Figure 4 The limiting frame 3 has multiple sets of material troughs 7 inside, multiple sets of small diameter weight reduction holes 8 and large diameter weight reduction holes 9 inside, and multiple sets of exhaust holes 15 inside. The exterior of the small diameter weight reduction hole 8 corresponds one-to-one with the exterior of the small diameter weight reduction hole 6, the exterior of the large diameter weight reduction hole 9 corresponds one-to-one with the exterior of the large diameter weight reduction hole 5, and the exterior of the exhaust hole 15 corresponds one-to-one with the exterior of the exhaust hole 14.

[0027] Specifically, the material trough 7 is used to facilitate the flow of sand through the fixture during the sandblasting process, avoiding sand accumulation; the small-diameter weight reduction hole 8 and the large-diameter weight reduction hole 9 are used to reduce the overall weight of the limit frame 3; and the exhaust hole 15 is used for ventilation to prevent air stagnation during bonding.

[0028] Reference Figure 1 and Figure 2 The pin post 2 is provided with a second base plate 10 on its exterior. The interior of the second base plate 10 is provided with multiple sets of sand leakage and anti-cavity grooves 11. The exterior of the second base plate 10 is attached to the upper surface of the limiting frame 3. The interior of the second base plate 10 is provided with multiple sets of small-diameter weight reduction holes 12 and large-diameter weight reduction holes 13. The exterior of the second base plate 10 is provided with multiple sets of vent holes 16. The exterior of the small-diameter weight reduction hole 12 corresponds one-to-one with the exterior of the small-diameter weight reduction hole 8. The exterior of the large-diameter weight reduction hole 13 corresponds one-to-one with the exterior of the large-diameter weight reduction hole 9. The exterior of the vent hole 16 corresponds one-to-one with the exterior of the vent hole 15.

[0029] Specifically, the second base plate 10 is used to connect the pin column 2. The isolation can prevent the products in the material tray from moving between each other and causing product stacking. The sand leakage and air-avoiding groove 11 is used to leak sand and avoid sand accumulation. The small diameter weight reduction hole 12 and the large diameter weight reduction hole 13 are used to reduce the overall weight of the second base plate 10. The exhaust hole 16 is used for ventilation and air permeability to prevent air stagnation during bonding.

[0030] Working principle: First, prepare the products to be sandblasted. After assembling the first base plate 1 and the limiting frame 3 with pins 2 for positioning, add an appropriate number of limiting frames 3 according to the height of the products. Place the products one by one into the material trough 7 of the fixture. Remove the pins 2, and then place the sandblasting fixture with the products on the conveyor belt at the feed end of the automatic sandblasting machine, allowing it to be sandblasted evenly on the automatic sandblasting machine. After the fixture full of products comes out from the discharge end of the automatic sandblasting machine, insert the pins 2 along the positioning holes, and use the limiting frames 3 to snap them together by flipping them 180° with both hands, so that the products fall into the material trough 7 of the limiting frames 3. Repeat the previous steps to remove the sandblasted products and place them in place to check the sandblasting effect. This fixture not only avoids sand accumulation and keeps the bottom surface of the workpiece clean and stable, but also achieves the effect of quickly positioning the first base plate 1, the limiting frame 3, and the second base plate 10, making it easy to fit together.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
