Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, and in particular to a surface shot blasting cleaning device. Background Technology

[0002] In the automotive wheel manufacturing industry, surface shot blasting equipment is used to remove oxide scale, oil stains, and minor rust from wheel surfaces, as well as some tiny bumps and burrs.

[0003] The existing Chinese utility model patent with authorization announcement number CN216681777U and patent name "A special clamp for shot blasting machine" discloses a clamp for shot blasting machine, including a base, a fixed column, a turntable, a clamping device and a rotating device. The fixed column is located inside the base, the turntable is rotatably mounted on the base, the clamping device is located inside the base and the turntable, and the rotating device is located inside the base and connected to the turntable.

[0004] However, the aforementioned shot blasting machine fixture has the following defects:

[0005] 1. In the aforementioned patent, when the shot from the shot blasting machine is projected onto the wheel, the clamp prevents the shot from impacting the contact surface between the clamp and the wheel, thus preventing the area from being effectively cleaned. Inadequate cleaning can lead to residual impurities in the area, such as molding sand from the casting process and forging scale. These impurities may cause corrosion problems, affect the structural integrity of the wheel, and create safety hazards during driving.

[0006] 2. In the above patent, the wheel is placed flat on the turntable and held in place by the clamp. The shot blasting machine can only directly act on the side of the wheel facing upwards. Since the other side of the wheel is blocked by the turntable, the shot is difficult to reach. This results in the wheel being cleaned only on one side, which is cumbersome and inefficient. Utility Model Content

[0007] The purpose of this invention is to provide a surface shot blasting cleaning device that has the effect of comprehensive cleaning and high efficiency.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a surface shot blasting cleaning device, comprising a housing, characterized in that: a shot blasting area is provided at the top of the housing, a door is provided on one side of the housing, two sets of alternating clamping or releasing clamping mechanisms are provided in the housing, each set of clamping mechanisms includes two clamps, the two clamps in each set of clamping mechanisms are arranged opposite to each other, at least one clamp in each set of clamping mechanisms is connected to the housing through a flipping mechanism, the clamp includes a clamping plate and a cylinder, the clamping plate is connected to the telescopic shaft of the cylinder, and the cylinder is rotatably connected to the side wall of the housing through a turntable.

[0009] By adopting the above technical solution, the two sets of clamping mechanisms alternately clamp or release the wheel, and the shot thrown from the shot blasting area cleans the surface of the wheel. It can first clean the surface of the wheel that is not clamped by one set of clamping mechanisms, and then clean the surface that is not cleaned by the shot, thus cleaning the contact surface between the clamp and the wheel.

[0010] In addition, the flipping mechanism flips the wheel up and down, which can clean both the top and bottom surfaces of the wheel, ensuring that all surfaces of the wheel are shot-blasted and that the surface roughness, cleanliness and other indicators of the cleaned wheel meet the requirements, making the wheel safer to use.

[0011] The telescopic shaft of cylinder one extends or retracts, driving the clamping plate to hold or release the wheel. The structure is simple and the operation is convenient.

[0012] A further feature of this invention is that the flipping mechanism includes a flipping motor fixed outside the housing and a geared disc coaxial with and fixed on the turntable. A drive gear is fixed on the output shaft of the flipping motor, and the drive gear meshes with the geared disc.

[0013] By adopting the above technical solution, the drive gear on the output shaft of the flip motor drives the meshing gear disk to rotate. The gear disk is coaxial with the turntable and fixedly connected. The turntable is fixedly connected to the clamp. The gear disk drives the clamp to rotate, causing the wheel held by the clamp to flip up and down, thereby achieving the effect of cleaning the upper and lower surfaces of the wheel.

[0014] A further feature of this invention is that the clamping surface of the clamping plate is arc-shaped.

[0015] By adopting the above technical solution, the clamping surface of the clamping plate is arc-shaped, which can better fit the circumferential surface of the wheel and make the clamping more stable.

[0016] A further feature of this invention is that a soft pad is provided on the clamping surface of the clamping plate.

[0017] By adopting the above technical solution, the wheel surface is usually made of metal. During the shot blasting process, if the clamping plate comes into direct contact with the wheel, it may scratch or wear the wheel surface. The soft pad can play a buffering role and prevent the wheel surface from being scratched by the hard surface of the clamping plate.

[0018] A further feature of this invention is that a lifting worktable is provided at the bottom of the box body, the lifting worktable is located at the clamping center of the two clamping mechanisms, and the lifting worktable is connected to the bottom of the box body through a second cylinder.

[0019] By adopting the above technical solution, the lifting worktable can provide a stable support platform for the wheels and provide sufficient space for the wheels to rotate up and down.

[0020] The beneficial effects of this utility model are:

[0021] 1. Two sets of clamping mechanisms alternately clamp or release the wheel. The shot blasting area throws shot at the wheel to clean the wheel surface. It can first clean the surface of the wheel that is not clamped by one set of clamping mechanisms, and then clean the surface that is not cleaned by shot, thus cleaning the contact surface between the clamp and the wheel.

[0022] 2. The flipping mechanism flips the wheel up and down, which can clean both the top and bottom surfaces of the wheel, ensuring that all surfaces of the wheel are shot-blasted and that the surface roughness, cleanliness and other indicators of the cleaned wheel meet the requirements, making the wheel safer to use.

[0023] 3. The clamping surface of the fixture is arc-shaped, which can better fit the circumferential surface of the wheel and make the clamping more stable.

[0024] 4. The lifting platform can provide a stable support platform for the wheels and also provide enough space for the wheels to rotate up and down.

[0025] 5. Wheel surfaces are usually made of metal. During shot blasting, if the clamping plate comes into direct contact with the wheel, it may scratch or wear the wheel surface. The soft pad can act as a buffer to prevent the wheel surface from being scratched by the hard surface of the clamping plate. Attached Figure Description

[0030] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] like Figure 1 , 2 As shown, a surface shot blasting cleaning device includes a housing 1, with a shot blasting area 3 at the top inside the housing 1. A door 2 is provided on one side of the housing 1. Two sets of alternating clamping or releasing mechanisms are provided inside the housing 1. Each clamping mechanism includes two clamps, which are arranged opposite to each other. At least one clamp in each clamping mechanism is connected to the housing 1 via a flipping mechanism. Each clamp includes a clamping plate 6 and a cylinder 4. The clamping plate 6 is connected to the telescopic shaft of the cylinder 4. The cylinder 4 is connected to the side of the housing 1 via a turntable 5. The wall rotates and connects. In one set of clamping mechanisms, the telescopic shaft of cylinder 4 extends, driving the clamping plate 6 to clamp and fix the wheel. The shot blasting area 3 throws shot at the wheel, and the shot cleans the surface of the wheel that is not clamped. After cleaning for a period of time, the telescopic shaft of cylinder 4 in this set of clamping mechanisms retracts, driving the clamping plate 6 to release the wheel. Another set of clamping mechanisms clamps and fixes the wheel, continuing to clean the surface that was not cleaned by the shot. It can clean the contact surface between the clamp and the wheel. In addition, the flipping mechanism makes the wheel flip up and down, which can clean the upper and lower surfaces of the wheel.

[0032] The flipping mechanism includes a flipping motor 8 fixed outside the housing 1 and a geared disc 9 coaxial with and fixed on the turntable 5. A drive gear 7 is fixed on the output shaft of the flipping motor 8. The drive gear 7 meshes with the geared disc 9. When the drive gear 7 on the output shaft of the flipping motor 8 rotates, it drives the geared disc 9 to rotate. The geared disc 9 drives the clamp on the turntable 5 to rotate, thereby driving the fixedly clamped wheel to flip up and down.

[0033] The clamping surface of the clamping plate 6 is arc-shaped, which allows the arc-shaped clamping plate 6 to better fit the circumferential surface of the wheel and stably clamp the wheel.

[0034] The clamping surface of the clamping plate 6 is provided with a soft pad. During the clamping process, the soft pad can prevent the clamping plate 6 from scratching or abrading the wheel surface.

[0035] The bottom of the box body 1 is provided with a lifting worktable 11. The lifting worktable 11 is located at the clamping center of the two clamping mechanisms. The lifting worktable 11 is connected to the bottom of the box body 1 through cylinder 2 10. When cylinder 2 10 drives the lifting worktable 11 to rise, the support wheel is fixedly clamped by the clamping plate 6. When cylinder 2 10 drives the lifting worktable 9 to fall to the bottom of the box body 1, the wheel has enough space to rotate up and down.

[0036] The working process of this surface shot blasting cleaning equipment is as follows:

[0037] S1. Open the box door 2, control the lifting worktable 11 to rise, place the wheel to be processed on the lifting worktable 11, so that the workpiece is in the clamping area.

[0038] S2. Close the box door 2 and control a set of clamping mechanisms to clamp the wheel so that the lifting worktable 11 is lowered to the bottom of the box body 1. Then start the drive gear 7 on the flip motor 8 in the clamping mechanism to rotate, which drives the gear plate 9 that meshes with it to rotate. The gear plate 9 drives the clamp on the turntable 5 to rotate. The clamp drives the wheel to rotate up and down, realizing the up and down flip of the wheel. At this time, the shot blasting area 3 throws shot at the wheel, and the surface of the wheel that is not clamped is cleaned by the shot.

[0039] S3. After the surface of the wheel not being clamped is cleaned, turn off the flipping motor 8, and the wheel stops rotating. Control the extension shaft of cylinder 4 in another clamping mechanism to extend and clamp the opposite arc surfaces on the other two sides of the wheel. Then, retract the extension shaft of cylinder 4 in the first clamping mechanism to release the surface of the wheel not being cleaned by the shot. Then, start the flipping motor 8 in the other clamping mechanism to drive the wheel to rotate up and down. The surface not being cleaned by the shot flips up and down, so that the surface of the wheel not being cleaned by the shot is cleaned.

[0040] S4. After cleaning is complete, the box door 2 can be opened to remove the processed wheel and place the next wheel to be processed, and the above process can be repeated.
