Description

Technical Field

[0001] This utility model relates to the field of sandblasting and polishing technology, and to an automatic sandblasting and polishing equipment for the surface treatment of lifting lugs. Background Technology

[0002] Sandblasting and polishing originated in the early stages of industrialization, initially developed to meet the needs of metal surface treatment. With industrial development, the requirements for workpiece surface quality have become increasingly stringent, leading to continuous improvement and refinement of the sandblasting and polishing process. It utilizes the impact of high-speed abrasive streams to clean and roughen the substrate surface. By using compressed air or liquid to accelerate and propel abrasive particles onto the workpiece surface, the surface roughness is reduced, resulting in a bright and smooth surface.

[0003] According to the public announcement (CN221936452U), an auxiliary polishing device for sandblasting fixtures is disclosed. This technology discloses a technical solution that includes "a sandblasting machine, a viewing window, an auxiliary frame, a slide rail, and a sliding table. The viewing window is located on the front side of the sandblasting machine, the auxiliary frame is located on the right side of the sandblasting machine, the slide rail is fixedly connected to the top of the auxiliary frame, and the sliding table is slidably connected to the top of the slide rail." This solution utilizes the sandblasting machine, viewing window, auxiliary frame, slide rail, sliding table, processing table, cavity, drive structure, and clamping structure. The drive structure moves the clamping structure, thereby clamping the workpiece. This solves the problem that if the workpiece moves during polishing, the surface of the workpiece will not be sandblasted, affecting the polishing effect and causing the surface polishing degree of the workpiece to fail to meet the specified requirements.

[0004] However, when the workpiece is sandblasted, the sand sprayed out by the clamping mechanism is blocked by the bottom and cannot flow down, thus causing it to accumulate. This affects the subsequent polishing work. Furthermore, when polishing the other side, it is necessary to manually remove, flip and fix it, which will also prolong the polishing process.

[0005] To address the aforementioned issues, this application proposes an automatic sandblasting and polishing equipment for the surface treatment of lifting lugs. Utility Model Content

[0006] This utility model addresses the technical problems existing in the prior art by providing an automatic sandblasting and polishing equipment for the surface treatment of lifting lugs.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An automatic sandblasting and polishing equipment for lifting lug surface treatment includes a sandblasting machine. The sandblasting machine has a clamping mechanism and a rotating mechanism inside. The clamping mechanism includes an electric telescopic rod mounted on the inner wall of the sandblasting machine. A clamping plate is mounted at the telescopic end of the electric telescopic rod. A flexible clamping mechanism is mounted on the side of the clamping plate. A transmission rod is rotatably connected to the side end of the clamping plate. A rotating plate is rotatably connected to the inner wall of the sandblasting machine. The side end of the rotating plate is rotatably connected to the transmission rod. The rotating mechanism includes a motor mounted on the inner wall of the sandblasting machine. A rotating rod is fixedly connected to the output end of the motor. A constraint groove is formed on the surface of the rotating rod. A drive pulley is rotatably connected to the surface of the clamping plate. A constraint block is mounted on the inner wall of the drive pulley. The surface of the constraint block is slidably connected to the rotating rod through the constraint groove. A transmission belt is drively connected to the surface of the drive pulley. A driven pulley is mounted on the side of the flexible clamping mechanism. The transmission belt is drively connected to the driven pulley.

[0008] The side end of the clamping plate is slidably connected to a guide rod, and the two ends of the guide rod are fixedly connected to the sandblasting machine. This design makes the clamping plate more stable when it moves, thanks to the guidance of the guide rod.

[0009] The bottom of the inner wall of the sandblasting machine is equipped with a recovery box, and the inner wall of the recovery box is equipped with a mesh screen. The sandblasting is recovered by the recovery box, and the mesh screen is used to prevent the lifting lugs from falling off.

[0010] The sandblasting machine has an observation window at the top of its side wall and a control panel on its side wall. The sandblasting and polishing process can be observed through the observation window, and the entire device can be operated using the control panel.

[0011] The sandblasting machine has a sliding table on its side, and a platform is slidably connected to the top of the sliding table. The surface of the platform has a reference groove. By setting up the platform, the lifting lugs can be placed on the platform, and the platform can be aligned using the reference groove and slid into the sandblasting machine for sandblasting and polishing.

[0012] The flexible clamping mechanism includes a clamping platform rotatably connected to the side wall of the clamping plate. The clamping platform has a liquid storage tank and a sliding groove inside. Several pistons are slidably connected to the clamping platform through the sliding groove. A top column is provided on the side of the piston. An anti-slip pad is provided on the side end of the top column. The liquid storage tank and the sliding groove are filled with hydraulic oil. By designing the mechanism, the top column on the clamping platform can extend and retract according to the shape of the contact surface of the lifting lug after contacting it, thereby more stably fixing the lifting lug and preventing it from falling off during sandblasting and flipping.

[0013] The beneficial effects of this utility model are as follows: the clamping plates are driven to move inward toward the lifting lug by the electric telescopic rod, and the two clamping plates move inward simultaneously and synchronously through the transmission rod and turntable until the lifting lug is fixed by the two flexible clamping mechanisms. At this time, the sandblasting can flow directly down without accumulating and affecting subsequent polishing. When the lifting lug needs to be flipped, the motor, rotating rod, constraint groove, constraint block, driving pulley and driven pulley rotate, thereby driving the flexible clamping mechanism to rotate, and thus flipping the lifting lug, eliminating the manual flipping operation and speeding up the polishing speed.

[0028] Reference Figures 1-4An automatic sandblasting and polishing equipment for surface treatment of lifting lugs includes a sandblasting machine 1. The sandblasting machine 1 has a clamping mechanism 2 and a rotating mechanism 3 internally. The clamping mechanism 2 includes an electric telescopic rod 201 mounted on the inner wall of the sandblasting machine 1. Two clamping plates 202 are mounted on the telescopic end of the electric telescopic rod 201; one is connected to the telescopic end of the electric telescopic rod 201, and the other is opposite it. Two flexible clamping mechanisms 4 are mounted on the side of the clamping plate 202. A transmission rod 203 is rotatably connected to the side end of the clamping plate 202. Two transmission rods 203 are provided. A rotating plate 204 is rotatably connected to the inner wall of the sandblasting machine 1. The side end of the rotating plate 204 is rotatably connected to the transmission rod 203. The two clamping plates 202 are linked through the transmission rod 203 and the rotating plate 204 to fix the lifting lugs. The rotating mechanism 3 includes a motor 301 installed on the inner wall of the sandblasting machine 1. A rotating rod 302 is fixedly connected to the output end of the motor 301. A constraint groove 303 is opened on the surface of the rotating rod 302. A drive pulley 304 is rotatably connected to the surface of the clamping plate 202. A constraint block 30 is provided on the inner wall of the drive pulley 304. 5. The surface of the constraint block 305 is slidably connected to the rotating rod 302 through the constraint groove 303. The constraint block 305 and the constraint groove 303 are compatible. The surface of the driving pulley 304 is connected to the transmission belt 306. The side of the flexible clamping mechanism 4 is provided with a driven pulley 307. The driven pulley 307 drives the flexible clamping mechanism 4 to rotate. The transmission belt 306 is connected to the driven pulley 307. The electric telescopic rod 201 drives the clamping plate 202 to move inward toward the lifting lug. While the clamping plate 202 moves, the transmission rod 203 is adjusted to drive the clamping plate 202 to rotate. The rotating plate 204 rotates, and the other transmission rod 203 moves accordingly, so that the two clamping plates 202 move inward simultaneously until the lifting lug is fixed by the two flexible clamping mechanisms 4. When the lifting lug needs to be flipped, the motor 301 is started. The motor 301 drives the rotating rod 302 to rotate, so that the motor 301 drives the driving pulley 304 to rotate through the constraint groove 303 and the constraint block 305. The driving pulley 304 drives the driven pulley 307 to rotate through the transmission belt 306, thereby driving the flexible clamping mechanism 4 to rotate, and thus flipping the lifting lug.

[0029] Reference Figure 2 The side end of the clamping plate 202 is slidably connected to a guide rod 5. The inner circumference of the clamping plate 202 and the outer circumference of the guide rod 5 are matched. The two ends of the guide rod 5 are fixedly connected to the sandblasting machine 1, so that the clamping plate 202 slides on the guide rod 5 when it moves, and is more stable by the guidance of the guide rod 5.

[0030] Reference Figure 1The bottom of the inner wall of the sandblasting machine 1 is equipped with a recovery box 6, and the inner wall of the recovery box 6 is equipped with a mesh 7. The aperture of the mesh 7 is larger than that of the sandblasting and smaller than that of the lifting lug. The top of the side wall of the sandblasting machine 1 is equipped with an observation window 8, and the side wall of the sandblasting machine 1 is equipped with a control panel 9. The sandblasting is recovered by the recovery box 6 and the lifting lug is prevented from falling off by the mesh 7. The sandblasting and polishing situation can be observed through the observation window 8, and the entire device can be controlled through the control panel 9.

[0031] Reference Figure 1 A slide table 10 is provided on the side of the sandblasting machine 1. A platform 11 is slidably connected to the top of the slide table 10. A reference groove 12 is provided on the surface of the platform 11. The length of the reference groove 12 is equal to the length of the flexible clamping mechanism 4. The lifting lug can be aligned with the flexible clamping mechanism 4 through the reference groove 12. The lifting lug can be placed on the platform 11 by setting the platform 11. The platform 11 is aligned by the reference groove 12 and slid into the sandblasting machine 1 to fix it for sandblasting and polishing.

[0032] Reference Figure 3 - Figure 5 The flexible clamping mechanism 4 includes a clamping platform 401 rotatably connected to the side wall of the clamping plate 202. The clamping platform 401 has a liquid storage tank 402 and a sliding groove 403 inside. Several pistons 404 are slidably connected to the clamping platform 401 via the sliding groove 403. The outer periphery of each piston 404 is adapted to the inner periphery of the sliding groove 403. A top post 405 is provided on the side of each piston 404, and an anti-slip pad 406 is provided at the side end of each top post 405. The pistons 404, top posts 405, and anti-slip pads 406 correspond one-to-one. The anti-slip pads 406 enhance the friction between the top posts 405 and the lifting lugs. The friction makes it more stable. The inside of the reservoir 402 and the slide 403 is filled with hydraulic oil 407. By setting it up so that when the top column 405 on the clamping platform 401 contacts the lifting lug, when part of the top column reservoir 402 is squeezed and stops moving, the clamping platform 401 continues to move inward. The squeezed top column 405 drives the piston 404 to make the hydraulic oil 407 flow, which can push the unsqueezed top column 405 to move towards the lifting lug until the lifting lug is fixed. Thus, it can be effectively clamped even when the contact surface of the lifting lug is irregular, preventing the lifting lug from falling off during sandblasting and flipping.

[0033] Working principle:

[0034] The automatic sandblasting and polishing equipment for surface treatment of lifting lugs first places the lifting lugs above the platform 11. Since the length of the reference groove 12 is the same as that of the flexible clamping mechanism 4, the points to be fixed can be aligned with the reference groove 12. After the platform 11 is placed, it is slid into the sandblasting machine 1 along the direction of the slide table 10. Then, the electric telescopic rod 201 is activated, which drives the clamping plate 202 to move inward toward the lifting lug. At the same time, the clamping plate 202 moves, and the transmission rod 203, which is rotatably connected to it, drives the rotating plate 204 to center on the point rotatably connected to the sandblasting machine 1. When the rotating plate 204 is rotated, the transmission rod 203 connected to the other end of the rotating plate 204 moves accordingly, so that the two clamping plates 202 move inward simultaneously along the rotating rod 302 until the lifting lug is fixed by the two flexible clamping mechanisms 4. When the lifting lug needs to be flipped, the motor 301 is started. The motor 301 drives the rotating rod 302 to rotate, so that the motor 301 drives the driving pulley 304 to rotate through the constraint groove 303 and the constraint block 305. The driving pulley 304 drives the driven pulley 307 to rotate through the transmission belt 306, thereby driving the flexible clamping mechanism 4 to rotate, and thus flipping the lifting lug.

[0035] In this automatic sandblasting and polishing equipment for surface treatment of lifting lugs, when some of the top columns 405 on the clamping platform 401 come into contact with the lifting lug, some of the top pin reservoirs 402 are squeezed and stop moving. The clamping platform 401 continues to move inward. The squeezed top columns 405 drive the piston 404 to make the hydraulic oil 407 flow, which can push the unsqueezed top columns 405 to move towards the lifting lug until the lifting lug is fixed. Thus, it can effectively clamp even when the contact surface of the lifting lug is curved or has an irregular shape, preventing the lifting lug from falling off during sandblasting and flipping.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
