Description

Technical Field

[0001] This utility model relates to the field of panel grinding equipment, specifically a panel grinding device. Background Technology

[0002] When grinding the panels, motors equipped with grinding wheel blades are often used. The sides of the grinding wheel blades can grind the composite panels, and the wheel ends can cut the composite panels. The panels are operated by holding the handle of the motor. However, existing grinding equipment cannot effectively control the grinding thickness.

[0003] According to the patent document CN219275082U, a refrigerated truck body panel grinding and cutting integrated device is disclosed. It includes a cutting machine, which comprises a motor and a wheel mounted on the working end of the motor. A handrail is provided on the side of the motor, and a mounting plate is provided at the bottom of the motor. A base plate is provided at the bottom of the mounting plate, and a clamping assembly for holding the motor is provided on the base plate. In use, the clamping assembly positions the motor, and a positioning tube positions the guide component. The guide component can contact the workpiece or the edge of the processing table. Furthermore, the device provides a handle that cooperates with the handrail, effectively improving the controllability of the wheel during the cutting and grinding process, which is beneficial to improving the processing quality of the workpiece. However, while the clamping assembly achieves positioning and grinding, it cannot maintain constant contact between the grinding mechanism and the plate material during the grinding process, which is inconvenient in use. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a panel grinding device to solve the problems mentioned in the background technology. The utility model has a novel structure. In use, the limiting roller is installed at the bottom of the panel. The tension generated by the support mechanism makes the grinding seat move downward and contact the panel for grinding. In addition, the width between the limiting roller and the grinding seat is fixed by fixing bolts, which can fix and clamp the panel for grinding.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a panel grinding device, comprising a base, on which a support tube and a positioning tube are fixed respectively. A threaded seat is fixed to the top of the support tube, and a threaded column is rotatably installed inside the threaded seat. A fixed seat is fixed to the top of the base, and a drive motor is fixedly installed on one side of the fixed seat. A protective cover is fixed to the other side of the fixed seat, and a grinding seat is rotatably installed inside the protective cover. The grinding seat is mounted on the drive motor via an output shaft, and a connecting plate is fixed to the protective cover.

[0006] Furthermore, a movable plate is movably installed on the side of the connecting plate and the protective cover, a fixing bolt is rotatably installed on the movable plate, a limit roller is rotatably installed at one end of the movable plate, and a plate is movably installed between the limit roller and the grinding seat.

[0007] Furthermore, a handle is fixed to the top of the base, and a fixed frame is movably installed at the bottom of the base, with a movable column and a positioning column fixedly installed on the fixed frame respectively.

[0008] Furthermore, the positioning column is movably installed inside the positioning tube, a limiting plate is fixed on the movable column, a reset mechanism is fixed on the limiting plate, and the movable column is movably installed inside the support tube.

[0009] Furthermore, a limiting ring is fixed on the inner wall of the support tube, the limiting ring is movable and cooperates with the limiting disk, and a support disk is fixed at one end of the reset mechanism, the support disk is movable and contacts the threaded column.

[0010] Furthermore, a groove is provided between the connecting plate and the protective cover, and a slider is movably installed inside the groove, with one end of the slider fixed to the movable plate.

[0011] Furthermore, a limiting groove is formed on the inner wall of the slide, and a support mechanism is fixed inside the limiting groove. A limiting block is fixed at one end of the support mechanism, and the limiting block is fixed on both sides of the slider. A fixing hole is formed on the slider, and a threaded hole is formed on the inner wall of the slide.

[0012] Furthermore, a support roller is rotatably mounted inside the fixed frame, and a track is movably mounted on the support roller.

[0013] The beneficial effects of this utility model are:

[0014] In this invention, the limiting roller is installed at the bottom of the plate during use. The tension generated by the support mechanism keeps the grinding seat moving downward and contacting the plate for grinding. In addition, the width between the limiting roller and the grinding seat is fixed by fixing bolts, which can fix and clamp the plate for grinding.

[0015] In this invention, the threaded column compresses and contracts the reset mechanism during use. After the reset mechanism contracts, the distance the movable column moves is reduced. By adjusting the distance, the height of the grinding seat is adjusted after the base presses against the fixed frame. Thus, the grinding thickness is adjusted by the cooperation of the threaded seat and the movable column.

[0016] This type of panel grinding device has a fixed frame that supports the track through a support roller. The track helps to increase the contact area with the moving point, and the base can always maintain stable movement when grinding uneven panels. Attached Figure Description

Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figures 1 to 6This utility model provides a technical solution: a panel grinding device, including a base 1, on which a support tube 2 and a positioning tube 5 are fixed respectively. A threaded seat 3 is fixed to the top of the support tube 2, and a threaded column 4 is rotatably installed inside the threaded seat 3. A fixed seat 7 is fixed to the top of the base 1. A drive motor 8 is fixedly installed on one side of the fixed seat 7, and a protective cover 9 is fixed to the other side of the fixed seat 7. A grinding seat 10 is rotatably installed inside the protective cover 9. The grinding seat 10 is mounted on the drive motor 8 through an output shaft. A connecting plate 11 is fixed to the protective cover 9. A movable plate 12 is movably installed on the side of the connecting plate 11 and the protective cover 9. A fixing bolt 13 is rotatably installed on the movable plate 12. A limiting roller 14 is rotatably installed at one end of the movable plate 12. A plate 29 is movably installed between the limiting roller 14 and the grinding seat 10. After the fixing bolt 13 is fixedly installed inside the threaded hole 18 at the corresponding height, the position of the limiting roller 14 is limited and fixed, thereby increasing the stability of the grinding seat 10 during grinding.

[0026] In this embodiment, a handle 6 is fixed to the top of the base 1, and a fixed frame 26 is movably installed at the bottom of the base 1. A movable column 21 and a positioning column 25 are fixedly installed on the fixed frame 26. The positioning column 25 is movably installed inside the positioning tube 5. A limit plate 22 is fixed on the movable column 21, and a reset mechanism 24 is fixed on the limit plate 22. The movable column 21 is movably installed inside the support tube 2, and a limit ring 30 is fixed on the inner wall of the support tube 2. The limit ring 30 movably cooperates with the limit plate 22. A support plate 23 is fixed to one end of the reset mechanism 24, and the support plate 23 movably contacts the threaded column 4. The reset mechanism 24 is a reset spring. When the handle 6 pushes the base 1 downward, the movable column 21 squeezes the reset mechanism 24 to provide a suitable height for the descent of the base 1. After the squeezing force is released, the reset mechanism 24 can push the base 1 upward so that the grinding seat 10 is quickly separated from the grinding point.

[0027] In this embodiment, a sliding groove 15 is formed between the connecting plate 11 and the protective cover 9. A slider 19 is movably installed inside the sliding groove 15. One end of the slider 19 is fixed to the movable plate 12. A limiting groove 16 is formed on the inner wall of the sliding groove 15. A support mechanism 17 is fixed inside the limiting groove 16. A limiting block is fixed at one end of the support mechanism 17. The limiting block is fixed on both sides of the slider 19. A fixing hole 20 is formed on the slider 19. A threaded hole 18 is formed on the inner wall of the sliding groove 15. A support roller 27 is rotatably installed inside the fixing frame 26. A track 28 is movably installed on the support roller 27. The support mechanism 17 is a support spring. The support spring drives the slider 19 and the movable plate 12 to move upward. After the movable plate 12 moves upward, the limiting roller 14 contacts the plate 29 to provide a limiting support point for the grinding seat 10.

[0028] When using this device, the limiting roller 14 first moves the movable plate 12 downwards. After the movable plate 12 moves downwards, the limiting roller 14 slides and is installed at the bottom of the plate 29. The grinding seat 10 moves to the top of the plate 29. When it is necessary to stably clamp the grinding point during grinding, the fixing bolt 13 is fixed inside the threaded hole 18 at a suitable height. After the fixing bolt 13 is installed, the movable plate 12 cannot move. During the subsequent up and down movement of the base 1, the grinding seat 10 and the limiting roller 14 always maintain clamping on the plate 29 to avoid the danger caused by the separation of the grinding seat 10 from the plate 29. When it is necessary to adjust the grinding seat 10 by moving it up and down, the fixing bolt 13 is removed from the inside of the threaded hole 18. Under the action of external force, the grinding seat 10 adjusts according to the plate 29. The shape of 9 moves up and down repeatedly for grinding. When it is necessary to control the grinding thickness, the threaded column 4 is rotated and moved downward. The threaded column 4 pushes the support plate 23 downward. After the support plate 23 moves downward, it squeezes the reset mechanism 24. When the reset mechanism 24 is compressed to half its length, it stops moving. Later, the handle 6 pushes the base 1 down. When the base 1 is down, the reset mechanism 24, which is not fully retracted by the movable column 21, squeezes again. The distance of the second squeeze is the distance that the base 1 is lowered. By pressing, the grinding seat 10 performs quantitative grinding on the grinding point. When the grinding is finished, the pressing force of the base 1 is released. Under the push of the reset mechanism 24, the grinding seat 10 and the base 1 move upward and quickly separate from the grinding point, effectively saving the force to move the base 1 upward.
