[0002] In the furniture and bathroom industry, towel racks, bath towel racks and other hardware bring convenience to people's daily lives. Generally, towel racks, bath towel racks and other hardware are made of square or round tubes. Before splicing, multiple surface treatment processes are required, including polishing, acid and alkali cleaning, phosphating, and painting.

[0003] Grinding hardware is a crucial step in the manufacturing and processing process, directly affecting the quality, performance, and service life of the product. Grinding removes surface defects such as burrs, scratches, and oxide layers, making the hardware smoother and more aesthetically pleasing. Grinding is commonly done using equipment such as grinding wheels and polishing machines. However, existing grinding methods are not uniform enough for grinding round tubes with arc shapes, have low grinding efficiency, and cannot accurately control the grinding force. Utility Model Content

[0004] The technical problem this invention aims to solve is that grinding the outer arc-shaped outer wall of a round tube with a grinding disc is inefficient and results in poor uniformity, while also making it difficult to accurately control the grinding force.

[0005] To solve the above technical problems, the present invention provides the following technical solution: The present invention proposes a surface polishing device for processing small hardware parts, including a base, a support frame on the base and a slider slidably mounted on the support frame, a driving component for driving the slider on the support frame, an L-shaped bracket on the slider and a polishing component on the L-shaped bracket.

[0006] The grinding assembly includes an electric telescopic rod located at the top of an L-shaped bracket, and an upper seat located at the movable end of the electric telescopic rod. A mounting frame is slidably mounted inside the upper seat. Two sets of rotating rollers are rotatably mounted inside the mounting frame, and grinding belts are mounted on the rotating rollers. A drive motor is located on the side wall of the mounting frame, and the power output shaft of the drive motor is connected to one set of rotating rollers. A buffer spring is located at the bottom of the upper seat, and the lower end of the buffer spring is connected to the top of the mounting frame. A pressure sensor is also located between the upper seat and the mounting frame.

[0007] Preferred technical solution 1: The driving component includes a screw that is rotatably disposed on the opposite side wall inside the support frame, and an adjusting motor disposed on the side wall of the support frame.

The support frame is provided with a guide groove and a slider is slidably disposed in the guide groove and its bottom is threadedly connected to the screw.

[0008] Preferred technical solution 2: The base is also symmetrically provided with two sets of support components. The support components include a slide plate that is slidably provided on the base and a support block provided on the slide plate. The support block is provided with a U-shaped groove and two sets of support rollers are rotatably provided in the U-shaped groove. The base is also provided with multiple sets of positioning holes at equal intervals along the sliding direction of the slide plate. The slide plate is also provided with a positioning screw for threaded connection with the positioning holes.

[0009] Preferred technical solution 3: The base is provided with a positioning component in the middle. The positioning component includes a support rod vertically disposed on the base and a limiting block disposed on the top of the support rod. An electromagnet is disposed inside the limiting block.

[0010] Preferred technical solution four: The L-shaped bracket is equipped with a controller, and the electric telescopic rod, electromagnet, pressure sensor, adjusting motor and drive motor are all electrically connected to the controller.

[0011] Preferred technical solution five: The surface of the support roller is covered with an anti-slip rubber sleeve.

[0012] The surface polishing device for processing small hardware parts proposed in this utility model has the following beneficial effects achieved by adopting the above structure:

[0013] (1) The drive assembly precisely adjusts the slider stroke through the screw and the regulating motor.

[0023] Example 1

[0024] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: A surface polishing device for processing small hardware parts includes a base 1, a support frame 2 on the base 1 and a slider 3 slidably mounted on the support frame, a drive assembly for driving the slider 3 on the support frame 2, an L-shaped bracket 4 on the slider 3 and a polishing assembly 5 on the L-shaped bracket 4; the polishing assembly 5 includes an electric telescopic rod 6 on the top of the L-shaped bracket 4 and an upper seat 7 on the movable end of the electric telescopic rod 6, a mounting frame 8 slidably mounted inside the upper seat 7, two sets of rotating rollers 9 rotatably mounted inside the mounting frame 8 and a polishing belt 10 mounted on the rotating rollers 9, a drive motor 11 on the side wall of the mounting frame 8 and the power output shaft of the drive motor 11 connected to a set of rotating rollers 9, a buffer spring 12 at the bottom of the upper seat 7 and the lower end of the buffer spring 12 connected to the top of the mounting frame 8, and a pressure sensor 13 between the upper seat 7 and the mounting frame 8.

[0025] like Figure 1As shown, the drive assembly includes a screw 14 rotatably disposed on the opposite side wall inside the support frame 2, and an adjustment motor 15 disposed on the side wall of the support frame 2. The power output shaft of the adjustment motor 15 is connected to the screw 14. The support frame 2 is provided with a guide groove 16 and the slider 3 is slidably disposed in the guide groove 16 and its bottom is threadedly connected to the screw 14.

[0026] Example 2

[0027] Based on Example 1, such as Figure 3 As shown, two sets of support components 17 are symmetrically arranged on the base 1. The support components 17 include a slide plate 18 that is slidably arranged on the base 1 and a support block 19 arranged on the slide plate 18. A U-shaped groove 20 is opened on the support block 19, and two sets of support rollers 21 are rotatably arranged in the U-shaped groove 20. Multiple sets of positioning holes 22 are also equidistantly arranged on the base 1 along the sliding direction of the slide plate 18. The slide plate 18 is also provided with a positioning screw 23 for threaded connection with the positioning hole 22. The surface of the support roller 21 is covered with an anti-slip rubber sleeve.

[0028] like Figure 4 As shown, a positioning component is provided in the middle of the base 1. The positioning component includes a support rod 24 vertically mounted on the base 1 and a limiting block 25 located at the top of the support rod 24. An electromagnet 26 is provided inside the limiting block 25. The limiting block 25 cooperates with two sets of support blocks 19 to support the round tube and fixes the round tube by means of the electromagnet 26 to prevent rotation during grinding.

[0029] The L-shaped bracket 4 is equipped with a controller 27, and the electric telescopic rod 6, electromagnet 26, pressure sensor 13, regulating motor 15 and drive motor 11 are all electrically connected to the controller 27.

[0030] In practical use, adjust the distance between the two sets of support components 17 according to the length of the round tube to be processed, fix the slide plate 18 by the positioning screw 23, place the round tube, and place the round tube horizontally in the U-shaped groove 20 of the support rollers 21 on both sides to ensure that both ends of the round tube are in contact with the support rollers 21. Turn on the electromagnet 26 to generate magnetic attraction to assist in fixing the round tube. Preset the pressure of the electric telescopic rod 6 to 80N, adjust the speed of the drive motor 11 according to the grinding roughness requirements, set the horizontal movement speed of the slider 3, start the grinding belt 10 under no-load condition, and observe whether the reading of the pressure sensor 13 is 0N.

[0031] During the specific grinding process, the motor 15 drives the screw 14 to move the slider 3 to the starting end of the round tube. The electric telescopic rod 6 is then activated to press down until the pressure sensor 13 displays the set pressure value. The pressure sensor 13 monitors pressure fluctuations in real time and automatically compensates for height deviations through the buffer spring 12. After grinding on one side is completed, the electromagnet 26 is turned off to adjust the grinding surface. The round tube can be rotated at a certain angle by the grinding belt 10. Then, the electromagnet 26 is activated to fix the round tube and continue grinding. The operation is simple, convenient and efficient.
