Description

Technical Field

[0001] This utility model relates to the field of machining and surface treatment technology, and in particular to a polishing device with a liftable worktable. Background Technology

[0002] In modern manufacturing, the smoothness, flatness, and appearance quality of workpiece surfaces are important indicators for measuring product quality. Polishing, as a key surface treatment process, is widely used in hardware, mold making, automotive, electronics, medical device and other fields to remove burrs, oxide layers, scratches, improve surface roughness, or achieve a mirror finish.

[0003] Traditional polishing equipment often uses a fixed worktable with a non-adjustable height. For workpieces of different thicknesses or shapes, operators need to frequently change fixtures or add shims to elevate the workpiece in order to align the surface to be processed with the polishing head. This operation is cumbersome and inefficient.

[0004] Therefore, a polishing device with a height-adjustable worktable needs to be designed to solve the above problems. Utility Model Content

[0005] To overcome the drawback of non-adjustable height, this utility model provides a polishing device with a height-adjustable worktable.

[0006] The technical solution of this utility model is: a polishing device with a liftable worktable, including a base plate, a movable frame, a screw, a movable block, a torsion member, a worktable, a fixed frame, a motor, and a polishing wheel. The movable frame is fixedly connected to the top left side of the base plate. The screw is rotatably connected inside the movable frame. The movable block is slidably connected to the inside of the movable frame, and the movable block is threadedly connected to the screw. The top of the screw passes through the movable frame and is fixedly connected to the torsion member. The worktable is fixedly connected to the right side of the movable block. The fixed frame is fixedly connected to the top of the base plate. The motor is fixedly connected to the upper part of the inner side of the fixed frame. The polishing wheel is fixedly connected to the output shaft at the bottom of the motor.

[0007] As a preferred technical solution of this utility model, it also includes a protective cover, with the upper part of the fixing frame fixedly connected to the protective cover, and the upper parts of the motor and polishing wheel located inside the protective cover.

[0008] As a preferred technical solution of this utility model, it also includes guide rods and linear bearings. Guide rods are fixedly connected to the front and rear sides of the top of the base plate, and linear bearings are fixedly connected to the front and rear sides of the worktable. Both guide rods pass through the corresponding linear bearings.

[0009] As a preferred technical solution of this utility model, it also includes a limiting block, and the top of the two guide rods are fixedly connected to the limiting block, the height of the top of the limiting block is less than the height of the bottom of the polishing wheel.

[0010] As a preferred technical solution of this utility model, it also includes a protective plate, which is fixedly connected to the top left side of the workbench and is located on the right side of the screw.

[0011] As a preferred technical solution of this utility model, it also includes a limiting plate, a positioning block and a push rod. The limiting plate is fixedly connected to both the front and rear sides of the top of the worktable, and the positioning block is fixedly connected to the right side of the top of the worktable. The push rod is slidably connected to the positioning block.

[0012] The beneficial effects of this utility model are as follows: 1. By setting up a moving frame, screw, moving block and torsion component, this utility model realizes continuous and precise adjustment of the worktable height. Operators can manually rotate the torsion component according to the thickness of different workpieces and processing requirements to quickly adjust the worktable to the best polishing position without changing the fixture or raising the workpiece. Furthermore, the protective plate blocks polishing debris from entering the screw drive area, protecting the core components from contamination and wear.

[0013] 2. This utility model forms a dual-point parallel guide system by setting two guide rods on the base plate and installing corresponding linear bearings on both sides of the worktable. This effectively constrains the movement trajectory of the worktable, ensuring that it remains stable and vertical during lifting and lowering. It avoids the shaking or swaying that may be caused by single-point support, improves the adjustment accuracy and the stability of the polishing operation. Furthermore, by setting a limit block at the top of the guide rod, the upward stroke of the worktable is physically limited to prevent it from rising excessively and damaging the equipment or colliding with the polishing wheel.

[0014] 3. This utility model provides operators with a safe tool for applying force through positioning blocks and push rods, avoiding hands from getting too close to dangerous areas. The protective cover prevents operators from accidentally touching the workpiece, and the limiting plate can prevent the workpiece from slipping during processing. Attached Figure Description

Detailed Implementation

[0020] Example: A polishing device with a height-adjustable worktable, such as... Figures 1-4 As shown, the assembly includes a base plate 1, a movable frame 2, a screw 3, a movable block 4, a torsion member 5, a worktable 6, a fixed frame 7, a motor 8, and a polishing wheel 9. The movable frame 2 is fixedly connected to the top left side of the base plate 1 by bolts. The screw 3 is rotatably connected inside the movable frame 2. The movable block 4 is slidably connected to the inside of the movable frame 2, and the movable block 4 is threadedly connected to the screw 3. The top of the screw 3 passes through the movable frame 2 and is fixedly connected to the torsion member 5. The worktable 6 is fixedly connected to the right side of the movable block 4. The fixed frame 7 is welded to the top of the base plate 1. The motor 8 is fixedly connected to the upper part of the inner side of the fixed frame 7 by bolts. The polishing wheel 9 is fixedly connected to the output shaft at the bottom of the motor 8.

[0021] like Figure 4 As shown, it also includes a protective cover 10, with the upper part of the fixing frame 7 fixedly connected to the protective cover 10, and the upper parts of the motor 8 and the polishing wheel 9 located inside the protective cover 10.

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, it also includes guide rods 11 and linear bearings 12. Guide rods 11 are fixedly connected to the front and rear sides of the top of the base plate 1, and linear bearings 12 are fixedly connected to the front and rear sides of the worktable 6. Both guide rods 11 pass through the corresponding linear bearings 12.

[0023] like Figure 3 and Figure 4 As shown, it also includes a limiting block 13. The top of both guide rods 11 are fixedly connected to the limiting block 13, and the top height of the limiting block 13 is less than the bottom height of the polishing wheel 9.

[0024] like Figure 1 and Figure 4 As shown, it also includes a protective plate 14. The protective plate 14 is fixedly connected to the top left side of the workbench 6 by bolts. The protective plate 14 is located to the right of the screw 3.

[0025] like Figure 1 and Figure 4 As shown, it also includes a limit plate 15, a positioning block 16 and a push rod 17. The limit plate 15 is fixedly connected to the front and rear sides of the top of the worktable 6 by bolts. The positioning block 16 is fixedly connected to the right side of the top of the worktable 6 by bolts. The push rod 17 is slidably connected to the positioning block 16.

[0026] When this device is used to polish a workpiece, the workpiece to be polished is first placed on the worktable 6. The height of the worktable 6 is adjusted according to the thickness of the workpiece and the required polishing position. The operator manually rotates the torsion member 5 located at the top of the moving frame 2. The torsion member 5 drives the screw 3 to rotate inside the moving frame 2. Since the moving block 4 is connected to the screw 3 by a thread and the moving block 4 is restricted to sliding up and down inside the moving frame 2, the rotational motion of the screw 3 is converted into the linear lifting motion of the moving block 4. The worktable 6 fixedly connected to the right side of the moving block 4 rises or falls synchronously.

[0027] To ensure that the worktable 6 moves smoothly without deflection or shaking during lifting, two parallel guide rods 11 are fixed on the front and rear sides of the top of the base plate 1. Linear bearings 12 are installed on the front and rear sides of the worktable 6 respectively. The two guide rods 11 pass through the corresponding linear bearings 12, and the linear bearings 12 slide along the guide rods 11 to provide precise linear guidance for the worktable 6 and ensure that it always moves vertically.

[0028] The limit block 13 prevents the worktable 6 from rising excessively. The limit block 13 at the top of the two guide rods 11 is lower than the bottom of the polishing wheel 9, ensuring that the worktable 6 will not collide with the polishing wheel 9 below at any height.

[0029] When the workbench 6 is raised to a suitable height, the limiting plates 15 on the front and rear sides of the top of the workbench 6 can limit the workpiece to prevent it from falling. The motor 8 in the fixed frame 7 is started. The output shaft at the bottom of the motor 8 drives the polishing wheel 9 to rotate at high speed. By pushing the push rod 17 to slide in the positioning block, the workpiece is pushed towards the rotating polishing wheel 9, so that its surface can be ground or polished. The protective cover 10 on the upper part of the fixed frame 7 effectively seals the high-speed rotating motor 8 and the upper part of the polishing wheel 9 to prevent the operator from accidentally touching the polishing wheel 9.

[0030] The protective plate 14 on the top left of the worktable 6 is located on the right side of the screw 3. It can prevent the debris generated during the processing from entering the screw 3 area and protect the precision transmission components. After polishing is completed, turn off the motor 8 and wait for the polishing wheel 9 to stop rotating completely before taking out the workpiece. If other workpieces need to be processed, the torsion member 5 can be rotated again to adjust the worktable 6 to a new height and repeat the above operation process.
