Description

Technical Field

[0001] This utility model relates to the field of sandblasting fixture technology, and in particular to a sandblasting force-relieving and deformation-preventing tooling for weak products. Background Technology

[0002] Sandblasting is a surface treatment process that uses compressed air or centrifugal force to propel abrasive materials (such as steel grit, glass beads, ceramic particles, etc.) at high speed onto the surface of a workpiece for purposes such as rust removal, deburring, cleaning, or increasing roughness. Its effects include improving coating adhesion, enhancing surface appearance, and strengthening metal parts. Process parameters (pressure, angle, abrasive type) directly affect the treatment results and it is suitable for various materials such as metals, plastics, and glass.

[0003] In traditional sandblasting operations, operators place the product to be treated directly on the worktable and perform sandblasting using fixed pressure parameters. After sandblasting, the product enters the inspection station for dimensional measurement; if it meets the requirements, it proceeds to the next process. For thin-walled parts or precision components, this process uses standard support methods, conventional metal abrasives, and follows general operating instructions to complete the entire sandblasting process.

[0004] Conventional sandblasting methods can easily cause plastic deformation of products, especially in structurally weak areas where significant dimensional deviations can occur. To meet the drawing requirements, a shaping process must be added for manual correction, which not only prolongs the production cycle but also increases manufacturing costs and the risk of secondary damage. Deformation has become a key bottleneck affecting production efficiency and product quality. To address this issue, a sandblasting stress-relieving and deformation-preventing tooling for weak products is proposed. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a sandblasting stress relief and deformation prevention tooling for weak products, which aims to improve the problem in the prior art that products are prone to plastic deformation, especially the obvious dimensional deviation in structurally weak parts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A sandblasting stress-relieving and deformation-preventing fixture for weak products includes a base plate. A lower tension spring fixing plate is installed on the top of the base plate. Multiple tension spring bodies are fixedly connected to the top of the lower tension spring fixing plate. An upper tension spring fixing plate is fixedly connected to the other end of each tension spring body. A main support bracket is fixedly connected to the top of the upper tension spring fixing plate. A fixing buckle is installed on the inner wall of the main support bracket. A side positioning block is installed on the inner wall of the main support bracket. A hand screw is threaded to the top of the main support bracket. A buckle reinforcing plate is rotatably connected to the bottom of the hand screw. A movable buckle is fixedly connected to the bottom of the buckle reinforcing plate. A product is installed on the side of the fixed buckle and the movable buckle. Restriction components are fixedly connected to both sides of the top of the buckle reinforcing plate.

[0008] As a further description of the above technical solution:

[0009] A reinforcing rib is fixedly connected to one side of the main support bracket, and one side of the side positioning block is in contact with one side of the product.

[0010] As a further description of the above technical solution:

[0011] Both sides of the top of the buckle reinforcing plate are fixedly connected with plug screws, the outside of which is slidably connected to the inner wall of the main support bracket, and a return spring is sleeved on the outside of the plug screws.

[0012] As a further description of the above technical solution:

[0013] One end of the return spring is fixedly connected to one side of the main support bracket, and the other end of the return spring is fixedly connected to one side of the screw.

[0014] This utility model has the following beneficial effects:

[0015] In this invention, the synergistic effect of the elastic clamping mechanism and the buffer system achieves dynamic stress dispersion during the sandblasting process, effectively reducing the impact force on the product. Combined with the automatic reset structure and precise positioning design, it ensures clamping stability and avoids subsequent shaping processes, significantly shortening the operation time. The overall structure adopts a reinforced design to improve the durability of the tooling, fully meeting the continuous operation requirements of automated production lines, and improving production efficiency while ensuring product quality.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1 to 2 This utility model provides an embodiment of a sandblasting stress-relieving and deformation-preventing fixture for weak products, comprising a base plate 1, which serves as the basic support structure for the entire fixture, ensuring stability during sandblasting. A tension spring lower fixing plate 2 is installed on the top of the base plate 1, which is used to fix the lower end of the tension spring body 3, providing support for the stress-relieving structure. Multiple tension spring bodies 3 are fixedly connected to the top of the tension spring lower fixing plate 2. The tension spring bodies 3 can elastically deform during sandblasting impact, absorbing the impact force and preventing the product 14 from deforming due to excessive force. An upper tension spring fixing plate 4 is fixedly connected to the other end of the tension spring body 3, which connects the upper end of the tension spring body 3 to the main support bracket 5, forming a complete stress-relieving structure. The main support bracket 5 is fixedly connected to the top of the upper tension spring fixing plate 4, which serves as the core frame of the fixture, providing installation positions for other functional components. A fixing buckle 7 is installed on the inner wall of the main support bracket 5, which is used to fix the lower end of the product 14, ensuring that the product 14 will not fall off during sandblasting.

[0022] The inner wall of the main support bracket 5 is equipped with a side positioning block 8, which laterally limits the product 14 to prevent it from shifting during sandblasting. The top of the main support bracket 5 is threaded with a hand screw 13, which allows the operator to quickly adjust the position of the movable buckle 9 to quickly fix the product 14. The bottom of the hand screw 13 is rotatably connected to a buckle reinforcement plate 10, which enhances the strength of the movable buckle 9 and ensures that it will not be damaged by force during sandblasting. The bottom of the buckle reinforcement plate 10 is fixedly connected to the movable buckle 9, which cooperates with the fixed buckle 7 to flexibly adjust the clamping distance to accommodate products 14 of different sizes. The product 14 is installed on the side of the fixed buckle 7 and the movable buckle 9, and the product 14 is clamped between the fixed buckle 7 and the movable buckle 9 to ensure its stability during sandblasting.

[0023] Both sides of the top of the snap-fit ​​reinforcing plate 10 are fixedly connected with limiting components. These limiting components restrict the movement range of the movable snap-fit ​​9, preventing excessive displacement that could cause the product 14 to loosen. A strength reinforcing rib 6 is fixedly connected to one side of the main support bracket 5. The strength reinforcing rib 6 enhances the rigidity of the main support bracket 5, preventing deformation during sandblasting. One side of the side positioning block 8 contacts one side of the product 14, ensuring that the product 14 maintains the correct position during sandblasting. Both sides of the top of the snap-fit ​​reinforcing plate 10 are fixedly connected with plug screws 12. The screw 12 and the return spring 11 work together to enable the movable buckle 9 to automatically reset after sandblasting. The screw 12 is externally slidably connected to the inner wall of the main support bracket 5 to ensure that the movable buckle 9 can move in a predetermined direction. The screw 12 is externally fitted with the return spring 11, which provides a reset force to the movable buckle 9 to ensure that it returns to its initial position after sandblasting. One end of the return spring 11 is fixedly connected to one side of the main support bracket 5, and the other end is fixedly connected to one side of the screw 12, forming a complete reset mechanism.

[0024] Working principle: Place product 14 on fixed buckle 7, and gently tighten hand screw 13 to move movable buckle 9 downward, which cooperates with fixed buckle 7 to clamp product 14. Due to the use of elastic clamping, product 14 can remain stable without being damaged by excessive clamping. When the sandblasting machine is working, high-speed sand particles impact the surface of product 14. The impact force generated will be transmitted to the tension spring body 3 through the main support bracket 5. The tension spring body 3 elastically deforms and absorbs the impact energy, causing the tooling to make slight avoidance, thereby reducing the direct impact force on product 14 and preventing deformation.

[0025] After sandblasting, the tension spring body 3 returns to its original position, driving the main support bracket 5 back to its original position. At the same time, the return spring 11 pushes the plug screw 12, causing the movable buckle 9 to automatically reset, making it easy to quickly remove the product 14. The side positioning block 8 ensures that the product 14 is in an accurate position, while the strength reinforcing rib 6 enhances the overall rigidity, making the tooling suitable for automated sandblasting production line operations, improving production efficiency and reducing manual processing costs.

[0026] 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.
