Description

Technical Field

[0001] This utility model relates to the field of grinding brush technology, and in particular to a grinding brush guiding device. Background Technology

[0002] A polishing brush is a tool used for surface treatment and processing. They are usually made of metal wire, synthetic fiber or other wear-resistant materials. The working principle of a polishing brush is to use the abrasive grains or particles on the brush surface to grind and polish the workpiece surface by rotating or vibrating, thereby improving the surface quality and precision.

[0003] In the existing technology, the grinding brush is not equipped with a guiding mechanism, which means that the grinding brush can only grind the surface of the object that needs to be ground. However, some objects also need to have their edges ground. The existing grinding brush cannot adjust the angle to effectively grind the edges of the object. Utility Model Content

[0004] To address the technical problem that existing grinding brushes cannot adjust their angle to grind the edges of objects, this utility model proposes a grinding brush guide device.

[0005] This utility model discloses a grinding brush guiding device, comprising a base plate, support rods fixedly installed at the four corners of the upper part of the base plate, a top plate fixedly installed on the upper part of each of the support rods, a rotating shaft rotatably connected to the middle of the top plate via ball bearings, the rotating shaft penetrating and extending to the lower part of the top plate, a mounting plate fixedly installed at the lower end of the rotating shaft extending from the lower part of the top plate, a motor fixedly installed on the upper part of the top plate, the output end of the motor fixedly connected to the upper part of the rotating shaft via a coupling, a grinding brush guiding mechanism provided at the lower part of the mounting plate, and a clamping mechanism provided at the upper part of the base plate.

[0006] Preferably, the clamping mechanism includes a straight slide groove, which is formed on the upper surface of the base plate, and multiple straight slide grooves are arranged in a circular array with the center of the base plate as the center. A slide rod is fixedly connected to the inner opposite surface of the straight slide groove, and a slider is slidably inserted into the arc surface of the slide rod. The outer surface of the slider is also slidably inserted into the inner wall of the straight slide groove. A clamping block is fixedly installed on the upper part of the slider. A limit spring is fixedly connected to one inner wall of the straight slide groove, and one end of the limit spring is fixedly connected to one end of the slider. The limit spring is wound around the arc surface of the slide rod.

[0007] The above technical solution involves setting up a clamping block, moving the clamping block to move the slider backward along the slide rod and compress the limiting spring, placing the object to be polished flat in the middle of the base plate, releasing the clamping block, and the limiting spring resetting to return the slider to its initial position, thus clamping and fixing the object to be polished.

[0008] Preferably, the grinding brush guiding mechanism includes a screw, and support plates are fixedly installed on both sides of the lower part of the mounting plate. The two ends of the screw are rotatably connected to the opposite surfaces of the two support plates via ball bearings. Limiting rods are also fixedly connected between the opposite surfaces of the two support plates. A sliding block is threadedly connected to the threaded surface of the screw. The surface of the sliding block is slidably inserted into the arc surface of the two limiting rods. A motor is fixedly installed on one side of one support plate. The output end of the motor is fixedly connected to one end of the screw via a coupling. A circular groove is formed on the lower surface of the top plate. An arc-shaped slider is slidably inserted into the inner wall of the circular groove. The lower part of the arc-shaped slider is fixedly connected to the upper part of the mounting plate.

[0009] Through the above technical solution, a second motor is set up, and the second motor drives the screw to rotate, so that the sliding block moves back and forth along the screw under the limit of the first limiting rod. A circular sliding block and an arc-shaped slider are set up to support and fix the first mounting plate, so that the first mounting plate can be stably subjected to force.

[0010] Preferably, a fixing plate is fixedly installed at the lower part of the sliding block, a fixing rod is fixedly installed at the lower part of the sliding block, a limiting rod two is fixedly connected to the middle part of the fixing plate, one end of the limiting rod two is fixedly connected to one side of the fixing rod, a fixing block is slidably inserted into the arc surface of the limiting rod two, an electric telescopic rod is fixedly installed at the lower part of the fixing block, a pin one is rotatably connected to the lower part of the fixing rod through a ball bearing, the pin one passes through and extends out of both sides of the fixing rod, support plates two are fixedly connected to the arc surfaces of the two ends of the pin one extending out of both sides of the fixing rod, the telescopic end of the electric telescopic rod is rotatably connected to the pin two through a ball bearing, the pin two passes through and extends out of both sides of the telescopic end of the electric telescopic rod, support plates three are fixedly connected to the arc surfaces of the two ends of the pin two extending out of both sides of the telescopic end of the electric telescopic rod, and mounting plates two are fixedly connected to the lower parts of both support plates two and both support plates three.

[0011] Through the above technical solution, a fixed rod and a fixed block are set. The fixed block slides on the second limiting rod, so that the electric telescopic rod at the bottom of the fixed block can slide left and right with the fixed block, changing the distance between the second electric telescopic rod and the fixed rod. The telescopic end of the electric telescopic rod is rotatably connected to the third support plate through the second pin. The lower part of the fixed rod is rotatably connected to the second support plate through the first pin. When the electric telescopic rod is started and the telescopic end moves down, the first pin of the second mounting plate can rotate downward with the center, so that the second mounting plate is tilted. The tilt of the second mounting plate causes the electric telescopic rod to slide inward along the limiting rod.

[0012] Preferably, a rotating shaft is rotatably connected to the middle of the mounting plate two via a ball bearing. The rotating shaft two passes through and extends out of the lower part of the mounting plate two. A motor three is fixedly installed on the upper part of the mounting plate two. The output end of the motor three is fixedly connected to the upper end of the rotating shaft two via a coupling. A grinding brush body is threadedly connected to one end of the rotating shaft two extending out of the lower part of the mounting plate two.

[0013] Through the above technical solution, motor three is set up. Starting motor three can drive shaft two to rotate, which in turn drives the grinding brush body to rotate, so that the grinding brush body can grind the object that needs to be ground.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. By setting up motor one, starting motor one can drive rotating shaft one to rotate, causing mounting plate one below the rotating shaft one to rotate around the first center of the rotating shaft. This allows the grinding brush guide mechanism below the mounting plate to perform all-round grinding on the object to be ground. The clamping mechanism is set up to clamp and fix the object to be ground, which solves the technical problem that the existing grinding brush cannot adjust the angle to grind the edge of the object.

[0016] 2. By setting a fixed rod and a fixed block, the fixed block slides on the limiting rod two, allowing the electric telescopic rod at the bottom of the fixed block to slide left and right with the fixed block, changing the distance between the electric telescopic rod two and the fixed rod. The telescopic end of the electric telescopic rod is rotatably connected to the support plate three through the pin two, and the lower part of the fixed rod is rotatably connected to the support plate two through the pin one. When the electric telescopic rod is activated and the telescopic end moves down, the pin one of the mounting plate two can rotate downward with the center, making the mounting plate two tilted. The tilt of the mounting plate two causes the electric telescopic rod to slide inward along the limiting rod, and the tilt of the mounting plate two also causes the grinding brush body to tilt at a certain angle, so that the grinding brush body can grind the edges of the object to be ground.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A grinding brush guiding device includes a base plate 1, with support rods 2 fixedly installed at the four corners of the upper part of the base plate 1. A top plate 3 is fixedly installed on the upper part of each of the support rods 2. A rotating shaft 4 is rotatably connected to the middle of the top plate 3 via a ball bearing. The rotating shaft 4 passes through and extends to the lower part of the top plate 3. A mounting plate 6 is fixedly installed at the lower end of the rotating shaft 4 extending from the lower part of the top plate 3. A motor 5 is fixedly installed on the upper part of the top plate 3. The output end of the motor 5 is fixedly connected to the upper part of the rotating shaft 4 via a coupling. A grinding brush guiding mechanism is provided at the lower part of the mounting plate 6, and a clamping mechanism is provided at the upper part of the base plate 1.

[0024] To clamp and fix the object to be polished, a clamping mechanism is provided. The clamping mechanism includes a straight slide groove 7, which is formed on the upper surface of the base plate 1. Multiple straight slide grooves 7 are arranged in a circular array with the center of the base plate 1 as the center. Slide rods 8 are fixedly connected to the inner opposite surfaces of the straight slide grooves 7. A slider 9 is slidably inserted into the arc surface of the slide rod 8. The outer surface of the slider 9 is also slidably inserted into the inner wall of the straight slide groove 7. A clamping block 10 is fixedly installed on the upper part of the slider 9. A limit spring 11 is fixedly connected to one inner wall of the straight slide groove 7. One end of the limit spring 11 is fixedly connected to one end of the slider 9. The limit spring 11 is wound around the arc surface of the slide rod 8.

[0025] By setting the clamping block 10, the slider 9 moves backward along the slide bar 8 and compresses the limiting spring 11. The object to be polished is placed flat in the middle of the base plate 1. The clamping block 10 is released, and the limiting spring 11 returns to the initial position, so that the clamping block 10 clamps and fixes the object to be polished.

[0026] To perform all-around polishing of the object, a grinding brush guiding mechanism is provided. The grinding brush guiding mechanism includes a screw 12. Support plates 13 are fixedly installed on both sides of the lower part of the mounting plate 16. The two ends of the screw 12 are rotatably connected to the opposite surfaces of the two support plates 13 through ball bearings. Limiting rods 14 are also fixedly connected between the opposite surfaces of the two support plates 13. A sliding block 15 is threadedly connected to the threaded surface of the screw 12. The surface of the sliding block 15 is also slidably inserted into the arc surface of the two limiting rods 14. A motor 16 is fixedly installed on one side of one support plate 13. The output end of the motor 16 is fixedly connected to one end of the screw 12 through a coupling. A circular groove 17 is opened on the lower surface of the top plate 3. An arc-shaped slider 18 is slidably inserted into the inner wall of the circular groove 17. The lower part of the arc-shaped slider 18 is fixedly connected to the upper part of the mounting plate 16.

[0027] Motor 2 16 is set up. When motor 2 16 is started, it drives screw 12 to rotate, so that sliding block 15 moves back and forth along screw 12 under the limit of limit rod 14. Circular sliding block and arc-shaped slider 18 are set up to support and fix mounting plate 6, so that mounting plate 6 can be stably subjected to force.

[0028] To enable the grinding guide mechanism to grind the edges of the object, a fixing plate 19 is fixedly installed at the lower part of the sliding block 15, and a fixing rod 20 is fixedly installed at the lower part of the sliding block 15. A limiting rod 21 is fixedly connected to the middle of the fixing plate 19. One end of the limiting rod 21 is fixedly connected to one side of the fixing rod 20. A fixing block 22 is slidably inserted into the arc surface of the limiting rod 21. An electric telescopic rod 23 is fixedly installed at the lower part of the fixing block 22. A pin 24 is rotatably connected to the lower part of the fixing rod 20 via a ball bearing. 4. A pin 24 extends through and out of both sides of the fixed rod 20. Support plates 25 are fixedly connected to the two ends of the fixed rod 20. The telescopic end of the electric telescopic rod 23 is rotatably connected to the pin 26 via ball bearings. The pin 26 extends through and out of both sides of the telescopic end of the electric telescopic rod 23. Support plates 37 are fixedly connected to the two ends of the telescopic end of the electric telescopic rod 23. Mounting plates 28 are fixedly connected to the lower parts of the two support plates 25 and the two support plates 37.

[0029] By setting a fixed rod 20 and a fixed block 22, the fixed block 22 slides on the limiting rod 21, so that the electric telescopic rod 23 at the bottom of the fixed block 22 can slide left and right with the fixed block 22, changing the distance between the electric telescopic rod 23 and the fixed rod 20. The telescopic end of the electric telescopic rod 23 is rotatably connected to the support plate 27 through the pin 26. The lower part of the fixed rod 20 is rotatably connected to the support plate 25 through the pin 14. When the electric telescopic rod 23 is activated and the telescopic end moves down, the pin 14 of the mounting plate 28 can rotate downward with the center of the circle, so that the mounting plate 28 is tilted. The tilt of the mounting plate 28 causes the electric telescopic rod 23 to slide inward along the limiting rod.

[0030] To enable the grinding brush to grind the object to be ground, a rotating shaft 29 is rotatably connected to the middle of the mounting plate 28 via a ball bearing. The rotating shaft 29 passes through and extends out of the lower part of the mounting plate 28. A motor 30 is fixedly mounted on the upper part of the mounting plate 28. The output end of the motor 30 is fixedly connected to the upper end of the rotating shaft 29 via a coupling. The end of the rotating shaft 29 extending out of the lower part of the mounting plate 28 is threadedly connected to the grinding brush body 31. By setting up the motor 30, starting the motor 30 can drive the rotating shaft 29 to rotate, which in turn drives the grinding brush body 31 to rotate, so that the grinding brush body 31 grinds the object to be ground.

[0031] Working principle: First, move the clamping block 10 to move the slider 9 backward along the slide rod 8 and compress the limiting spring 11. Place the object to be polished flat in the middle of the base plate 1. Release the clamping block 10, and the limiting spring 11 will reset, allowing the slider 9 to return to its initial position, thus clamping and fixing the object to be polished. Start the motor 30 to drive the rotating shaft 29 to rotate, which in turn drives the grinding brush body 31 to rotate, enabling the grinding brush body 31 to polish the clamped object. Motor 16 is started, causing screw 12 to rotate. This allows sliding block 15 to slide along screw 12 under the limiting action of the limiting rod, enabling the grinding brush body 31 to grind different areas of the clamped object. Motor 5 is started, driving shaft 4 to rotate, causing mounting plate 6 to move in a circular motion around shaft 4. A circular groove 17 and an arc-shaped slider 18 provide support for mounting plate 6, preventing it from being subjected to force on only one side. The interaction between motor 5 and motor 16... The combination of these mechanisms allows the grinding brush body 31 to perform all-around grinding on the clamped object. When grinding the edge of the object is required, firstly, motor 16 is started, causing screw 12 to rotate and slide sliding block 15 to a suitable position, positioning the grinding brush body 31 above the edge of the clamped object. When the electric telescopic rod 23 is started and the telescopic end moves downward, the mounting plate 28 rotates downward around pin 24, causing the mounting plate 28 to be tilted. The tilt of the mounting plate 28 causes the electric telescopic rod 23 to slide inward along the limit rod, maintaining the tilt angle of the mounting plate 28. The tilt of the mounting plate 28 also causes the grinding brush body 31 to tilt at a certain angle, allowing the grinding brush body 31 to grind the edge of the object to be ground. Motor 30 is started, causing the grinding brush body 31 to begin grinding the edge of the clamped object. Motor 5 is started, causing the grinding brush body 31 to rotate around pivot 4, completely grinding the edge of the clamped object.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
