Polisher with dustproof structure for construction engineering

Abstract

This utility model relates to the field of grinding machine technology and discloses a grinding machine with a dustproof structure for construction engineering. It includes a base with a clamp on its surface and a cylinder fixedly connected to the base. In this dustproof grinding machine, the slider passes through a groove, which limits the slider's position. When the slider rod slides within the arc-shaped groove, it forces the push rod to move the slider within the groove. Simultaneously, the push rod pushes the grinding block to contact the surface of the reinforcing bar or pipe. At this point, the reset rod is released, and a spring pushes the insert rod into the locking hole, preventing the rotating plate from rotating further. Then, the motor is started, and the motor's output shaft drives the rotating rod to rotate, causing the gear and its meshing linkage gear to rotate the linkage plate, allowing the grinding block to grind the surface of the reinforcing bar or pipe. The circumferentially arranged grinding blocks can position and grind reinforcing bars or pipes of different diameters.

Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, specifically a grinding machine with a dustproof structure for construction engineering. Background Technology

[0002] A sander is a common tool used for grinding, polishing, and finishing various materials. Sanders come in many types, categorized by power source (electric sanders, pneumatic sanders, etc.) and by application and material being processed (wall sanders, wood sanders, metal sanders, stone sanders, etc.). Electric sanders typically consist of a motor, transmission, grinding head, and handle. Users can choose different shapes and grits of grinding heads to achieve various sanding effects. Pneumatic sanders are driven by compressed air, offering higher speeds and power, suitable for applications requiring high sanding efficiency. Sanders are widely used in construction and decoration, metal processing, wood processing, and automotive repair. When using a sander, safety precautions must be taken. Wear appropriate protective equipment, such as goggles, a mask, and earplugs, to prevent injury from dust and debris. Follow operating procedures carefully to avoid equipment damage or personal injury due to improper operation.

[0003] However, during construction, there are slight discrepancies between the actual dimensions and the produced materials, such as steel bars and pipes. The steel bars and pipes need to be ground before installation. However, the steel bars and pipes on the construction site are of different sizes, and the existing grinding machines cannot grind steel bars and pipes of different sizes, which is not convenient. Furthermore, when workers use handheld grinding machines to grind steel bars and pipes, not only are dimensional deviations easy to occur, but also a lot of dust is produced, which affects the health of the workers. Utility Model Content

[0004] The purpose of this invention is to provide a grinding machine with a dustproof structure for construction engineering, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding machine with a dustproof structure for construction engineering, comprising a base, a clamp provided on the surface of the base, a cylinder fixedly connected to the surface of the base, and a control unit provided on the inner side of the base, the control unit comprising:

[0006] A dustproof box, which penetrates the base and is slidably connected, has a connecting plate fixedly connected to the side of the dustproof box, the surface of the connecting plate fixedly connected to the output shaft of the cylinder, a gearbox fixedly connected to the top surface of the dustproof box, a motor fixedly connected to the surface of the dustproof box, a rotating rod rotatably connected to the inner wall of the gearbox, the rotating rod fixedly connected to the output shaft of the motor, and a gear penetrating and fixedly connected to the rotating rod.

[0007] A linkage plate is rotatably connected to the inner wall of the dustproof box. When the motor is started, the output shaft of the motor drives the rotating rod to rotate, thereby causing the gear and the meshing linkage teeth to drive the linkage plate to rotate, so that the grinding block grinds the surface of the steel bar or pipe. The side of the linkage plate has a groove, and the inner side of the groove is fixedly connected to the linkage teeth, which mesh with the gear. The inner side of the linkage plate has a locking hole. The inner wall of the dustproof box is rotatably connected to a rotating plate. The reset rod will drive the insertion rod to retract, so that the insertion rod is no longer inserted into the locking hole. Then, the reset rod is moved to drive the rotating plate to rotate. The surface of the rotating plate has an arc-shaped groove.

[0008] Preferably, the inner side of the rotating plate is slidably connected with an insert rod. In use, the steel bar or metal pipe to be ground is placed into the clamp, and the steel bar or pipe is inserted into the dustproof box. The bolts in the clamp are then tightened to fix the pipe firmly. At this time, the reset rod is pushed down to slide along the reset groove, and the reset rod will drive the insert rod to retract. A spring is fixedly connected between the insert rod and the inner wall of the rotating plate.

[0009] Preferably, the surface of the linkage plate is provided with a sliding groove, and a slider is slidably connected through the inner side of the sliding groove. When the reset rod is moved, the reset rod drives the rotating plate to rotate. The arc-shaped groove on the surface of the rotating plate will abut against the slider, causing the slider to slide within the arc-shaped groove. However, because the slider passes through the sliding groove, the sliding groove limits the slider.

[0010] Preferably, the surface of the rotating plate is provided with a reset groove, and the surface of the insertion rod is fixedly connected with a reset rod. When the reset rod is released, the spring will push the insertion rod into the locking hole, so that the rotating plate can no longer rotate. The reset rod passes through the reset groove and is slidably connected.

[0011] Preferably, a support rod is fixedly connected to the inner side of the slide groove, and the support rod passes through the slider and is slidably connected.

[0012] Preferably, a second spring is fixedly connected between the slider and the groove, a push rod is fixedly connected to the surface of the slider, and a grinding block is fixedly connected to the top surface of the push rod. Because the slider passes through the groove, the groove limits the slider, so that when the slide rod slides in the arc groove, the push rod forces the slider to slide in the groove. A slide rod is fixedly connected to the side of the push rod, and the slide rod passes through the arc groove.

[0013] Compared with the prior art, this utility model provides a grinding machine with a dustproof structure for construction engineering, which has the following beneficial effects:

[0014] 1. The dustproof grinding machine used in this construction project has a slider that passes through a groove, which limits the slider. When the slider rod slides within the arc-shaped groove, it forces the push rod to move the slider within the groove. At the same time, the push rod pushes the grinding block to fit against the surface of the steel bar or pipe. When the reset rod is released, the spring pushes the insert rod into the locking hole, preventing the rotating plate from rotating. Then, the motor is started, and the motor's output shaft drives the rotating rod to rotate, which in turn drives the gear and its meshing linkage gear to rotate the linkage plate, allowing the grinding block to grind the surface of the steel bar or pipe. The circumferentially arranged grinding blocks can be used to position and grind steel bars or pipes of different diameters.

[0015] 2. The construction project uses a grinding machine with a dustproof structure. The grinding area is located inside the dustproof box, which prevents excessive dust from flying and affecting the health of the workers. Furthermore, the cylinder can automatically move the dustproof box back and forth to grind, eliminating the need for manual operation of the grinding machine, making the grinding work more convenient.

[0022] like Figures 1-5As shown, this utility model provides a technical solution: a grinding machine with a dustproof structure for construction engineering, including a base 1, a clamp 3 provided on the surface of the base 1, a cylinder 4 fixedly connected to the surface of the base 1, and a control unit 2 provided on the inner side of the base 1. The control unit 2 includes: a dustproof box 21, a connecting plate 22, a gearbox 23, a motor 24, a rotating rod 25, a linkage plate 26, a groove 27, a linkage tooth 28, a locking hole 29, a rotating plate 210, an arc groove 211, a plug rod 212, a first spring 213, a reset rod 214, a reset groove 215, a sliding groove 216, a slider 217, a support rod 218, a push rod 219, a grinding block 220, a sliding rod 221, a second spring 222, and a gear 223.

[0023] A dustproof box 21 penetrates the base 1 and is slidably connected. A connecting plate 22 is fixedly connected to the side of the dustproof box 21. The surface of the connecting plate 22 is fixedly connected to the output shaft of the cylinder 4. A gearbox 23 is fixedly connected to the top surface of the dustproof box 21. A motor 24 is fixedly connected to the surface of the dustproof box 21. A rotating rod 25 is rotatably connected to the inner wall of the gearbox 23. The rotating rod 25 is fixedly connected to the output shaft of the motor 24. A gear 223 is passed through and fixedly connected to the rotating rod 25. A linkage plate 26 is rotatably connected to the inner wall of the dustproof box 21. When the motor 24 is started, the output shaft of the motor 24 drives the rotating rod 25 to rotate, thereby causing the gear 223 and the cylinder 4 to rotate. The meshing linkage gear 28 drives the linkage plate 26 to rotate, so that the grinding block 220 grinds the surface of the steel bar or pipe. The side of the linkage plate 26 has a groove 27, and the inner side of the groove 27 is fixedly connected to the linkage gear 28. The linkage gear 28 meshes with the gear 223. The inner side of the linkage plate 26 has a locking hole 29. The inner wall of the dust box 21 is rotatably connected to the rotating plate 210. The reset rod 214 will drive the insertion rod 212 to retract, so that the insertion rod 212 is no longer inserted into the locking hole 29. Then, the reset rod 214 is moved to drive the rotating plate 210 to rotate. The surface of the rotating plate 210 has an arc groove 211. The inner side of the rotating plate 210 is slidably connected to the insertion rod 212. When in use, the steel bar or metal pipe to be ground is placed into the clamp 3, and the steel bar or pipe is inserted into the dust box 21. The bolts in the clamp 3 are then tightened to fix the pipe firmly. At this time, the reset rod 214 is pushed down to slide along the reset groove 215. The reset rod 214 will also cause the insertion rod 212 to retract. A spring 213 is fixedly connected between the insertion rod 212 and the inner wall of the rotating plate 210. The surface of the linkage plate 26 has a groove 216, and a slider 217 is slidably connected through the inner side of the groove 216. Moving the reset rod 214 causes the rotating plate 210 to rotate. The arc-shaped groove 211 on the surface of the rotating plate 210 abuts against the slider 221, causing the slider 221 to slide within the arc-shaped groove 211. However, because the slider 217 passes through the groove 216, the groove 216 limits the slider 217. The surface of the rotating plate 210 has a reset groove 215, and the surface of the insertion rod 212 is fixedly connected to the reset rod 214. Releasing the reset rod 214 causes the spring 213 to push the insertion rod 212 into the locking hole 29, preventing the rotating plate 210 from rotating further. The reset rod 214 passes through the reset groove 215 and is slidably connected. A support rod 218 is fixedly connected to the inner side of the groove 216, and the support rod 218 passes through the slider 217 and is slidably connected.A spring 222 is fixedly connected between slider 217 and groove 216. A push rod 219 is fixedly connected to the surface of slider 217. A grinding block 220 is fixedly connected to the top surface of push rod 219. Since slider 217 passes through groove 216, groove 216 limits slider 217. When slide rod 221 slides in arc groove 211, push rod 219 is forced to drive slider 217 to slide in groove 216. At the same time, push rod 219 pushes grinding block 220 to fit against the surface of steel bar or pipe. Slide rod 221 is fixedly connected to the side of push rod 219. Slide rod 221 passes through arc groove 211.

[0024] Based on the above implementation method, during use, the steel bar or metal pipe to be ground is placed into the clamp 3, and the steel bar or pipe is inserted into the dustproof box 21. The bolts in the clamp 3 are then tightened to secure the pipe firmly. At this time, the reset rod 214 is pushed down, causing it to slide along the reset groove 215. The reset rod 214 will also cause the insertion rod 212 to retract, preventing the insertion rod 212 from being inserted into the locking hole 29. Pushing the reset rod 214 again causes it to rotate the rotating plate 210. The arc-shaped groove 211 on the surface of the rotating plate 210 will abut against the sliding rod 221, causing the sliding rod 221 to slide within the arc-shaped groove 211. However, because the slider 217 passes through the sliding groove 216, the sliding groove 216 limits the slider 217, causing the sliding rod 221 to slide within the arc-shaped groove 211. When sliding within the groove 216, the push rod 219 forces the slider 217 to slide within the groove 216. Simultaneously, the push rod 219 pushes the grinding block 220 to contact the surface of the steel bar or pipe. At this point, the reset rod 214 is released, and the spring 213 pushes the insert rod 212 into the locking hole 29, preventing the rotating plate 210 from rotating. Then, the motor 24 is started, and the output shaft of the motor 24 drives the rotating rod 25 to rotate, thereby causing the gear 223 and the meshing linkage gear 28 to drive the linkage plate 26 to rotate, so that the grinding block 220 grinds the surface of the steel bar or pipe. The circumferentially arranged grinding block 220 can position and grind steel bars or pipes of different diameters. At the same time, the grinding area is located within the dustproof box 21 to prevent excessive dust from flying and affecting the health of the staff.

[0025] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
