Description

Technical Field

[0001] This invention relates to the field of polishing equipment technology, and more particularly to a hardware surface polishing device. Background Technology

[0002] Hardware processing, as a precision manufacturing process, relies on various high-precision mechanical equipment, such as lathes, milling machines, drilling machines, and polishing machines, to meticulously process raw materials. This process strictly adheres to the customer's drawings or sample requirements, transforming raw materials into parts with specific functions and shapes through a series of complex steps. These parts are diverse, covering all aspects of daily life, such as common screws, motor shafts, model car parts, and fishing tackle accessories. Hardware processing also plays a vital role in the electronics industry, for example, in speaker casings and power bank casings.

[0003] Existing hardware surface polishing devices generally achieve polishing by controlling the position of the workpiece or polishing structure to bring the workpiece into contact with the polishing structure. For example, Chinese Patent Publication No. CN214054821 U discloses "a hardware surface polishing device", which adjusts the position between the hardware and the polishing ball by extending and retracting the first electric cylinder. The structure is simple and easy to use. The stepper motor drives the threaded rod to rotate, thereby driving the moving block to move. The moving block drives the sliding frame to move, thereby changing the position of the hardware. The position of the polishing ball is adjusted by the second electric cylinder, which can make the polishing position angle more precise.

[0004] However, in actual use, the time required to install the workpiece to be processed and to remove the processed product affects the processing efficiency of the device, and the accumulation of debris generated during processing can affect the operation of the equipment and affect the processing accuracy. Summary of the Invention

[0011] Furthermore, a mounting bracket is fixedly installed on the processing table, a first cylinder is fixedly installed on the mounting bracket, and a cleaning brush is fixedly installed on the output shaft of the first cylinder, with the bristles of the cleaning brush contacting the loading tray.

[0012] Furthermore, a material leakage trough is provided on the processing table, and a material guide pipe is fixedly installed on the processing table. The material leakage trough is located on the moving path of the cleaning brush.

[0013] Furthermore, a brush is fixedly installed on the tray, and a retaining ring that cooperates with the brush is fixedly installed on the processing table. The retaining ring has an opening corresponding to the material leakage groove.

[0014] Furthermore, a bracket is fixedly installed on the processing table, and a second cylinder is fixedly installed on the bracket. The output shaft of the second cylinder is fixedly connected to the motor.

[0015] Furthermore, a mounting plate is fixedly mounted on the processing table, and a mounting post is threadedly connected to the mounting plate. A ball bearing is rotatably mounted on the upper end of the mounting post, and the upper end of the ball bearing contacts the mounting plate.

[0016] Furthermore, a conveying structure is fixedly installed on the processing table.

[0018] The present invention provides a surface polishing device for hardware parts, which has the following advantages:

[0019] In this invention, by setting a loading tray and setting multiple processing positions on the loading tray, the workpieces in the processing positions can be processed sequentially. Furthermore, during the processing and polishing, the processed workpieces can be taken out and the product to be processed can be placed instead, without affecting the polishing of the workpieces by the device, thus improving processing efficiency.

[0020] Secondly, in this invention, the unloading mechanism lifts the finished workpiece upwards to facilitate its removal, and the first cylinder drives the cleaning brush to clean the tray and workpiece, sweeping away the processing debris and discharging it along the discharge chute.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Reference Figure 1-5 A hardware surface polishing device includes a processing table 1 and a polishing mechanism 2. A loading tray 3 is provided on the processing table 1, and multiple processing positions 4 are provided on the loading tray 3. A motor 5 for driving the loading tray 3 is provided on the processing table 1, and a unloading mechanism 6 is provided between the loading tray 3 and the processing table 1.

[0029] The unloading mechanism 6 includes a through hole 61 opened in the processing position 4, a top column 62 is slidably arranged in the through hole 61, and a top block 63 that cooperates with the top column 62 is fixedly arranged on the processing table 1. A slope is opened on one side of the top block 63.

[0030] In this invention, by setting multiple processing positions 4 on the loading tray 3, the workpieces in the processing positions 4 can be processed sequentially. While processing and polishing, the processed workpieces can be taken out and the product to be processed can be placed. This will not affect the polishing of the workpieces by the device, thus improving the processing efficiency. The unloading mechanism 6 lifts the processed workpieces upwards, making it convenient to take out the processed workpieces.

[0031] Furthermore, in this embodiment, the unloading mechanism 6 also includes a guide rail 64 disposed on the processing table 1, the top block 63 has an arc-shaped structure, and the lower end of the top column 62 is fixedly provided with an arc-shaped block 65 that cooperates with the top block 63. The guide rail 64 restricts the movement trajectory of the arc-shaped block 65 so that the top column 62 can contact the top block 63 when the loading plate 3 rotates.

[0032] In this embodiment, a spring 66 is provided between the arc-shaped block 65 and the loading tray 3, and a support plate 67 that cooperates with the processing position 4 is fixedly provided at the upper end of the top column 62. The top column 62 is reset by the spring 66, which facilitates the installation of the workpiece to be processed.

[0033] Furthermore, in this embodiment, a mounting frame 7 is fixedly installed on the processing table 1, a first cylinder 71 is fixedly installed on the mounting frame 7, and a cleaning brush 72 is fixedly installed on the output shaft of the first cylinder 71. The bristles of the cleaning brush 72 are in contact with the tray 3. The cleaning brush 72 is moved by controlling the first cylinder 71 to clean the tray 3.

[0034] In this embodiment, a material discharge trough 73 is provided on the processing table 1, and a material guide pipe 74 is fixedly provided on the processing table 1. The material discharge trough 73 is located on the moving path of the cleaning brush 72. The material discharge trough 73 discharges the debris swept off by the cleaning brush 72, preventing the debris from accumulating and affecting the operation of the equipment.

[0035] It should be noted that in this embodiment, a brush 31 is fixedly installed on the tray 3, and a retaining ring 32 that cooperates with the brush 31 is fixedly installed on the processing table 1. The retaining ring 32 has an opening corresponding to the material discharge trough 73. By setting the retaining ring 32, debris is prevented from falling on the processing table 1 and the position of the debris is restricted. At the same time, the brush 31 rotates to sweep the debris scattered in the retaining ring 32 into the material discharge trough 73 for discharge.

[0036] Furthermore, in this embodiment, a bracket 8 is fixedly installed on the processing table 1, and a second cylinder 81 is fixedly installed on the bracket 8. The output shaft of the second cylinder 81 is fixedly connected to the motor 5. By controlling the position of the motor 5 and the worktable 3 through the second cylinder 81, the motor 5 and the worktable 3 can be moved upward to clean and remove the debris located below the worktable 3. In some embodiments, a guide rail is provided between the motor 5 and the processing table 1 to help fix the motor 5.

[0037] In this embodiment, a mounting plate 11 is fixedly installed on the processing table 1. A mounting post 12 is threadedly connected to the mounting plate 11. A ball bearing 13 is rotatably installed on the upper end of the mounting post 12. The upper end of the ball bearing 13 contacts the mounting plate 11. The ball bearing 13 and the mounting post 12 support the loading plate 3 to prevent the motor 5 from tilting due to excessive force.

[0038] In detail, in some embodiments, a conveying structure 9 is fixedly installed on the processing table 1. The conveying structure 9 includes a base 91, and a rotating structure 92 is provided on the base 91. The rotating structure 92 can be a rotary cylinder or other rotating structure. A third cylinder 93 is provided on the rotating structure 92. A pneumatic gripper 94 is provided at the output end of the third cylinder 93. The position of the pneumatic gripper 94 is controlled by the third cylinder 93 to remove the processed workpiece, or to install the workpiece to be processed into the processing position 4.

[0039] In some embodiments, an isolation cover 33 is fixedly provided at the bottom of the tray 3, and bristles are provided at the lower end of the isolation cover 33. The bristles are in contact with the processing table 1. The isolation cover 33 is provided to prevent debris from entering the guide rail 64 and accumulating, thus affecting the operation of the equipment.

[0040] Working method: During operation, the motor 5 drives the carrier plate 3 to rotate, and the workpieces in multiple processing positions 4 are sequentially transported to the bottom of the grinding mechanism 2 for grinding and polishing. As the carrier plate 3 rotates, the arc block 65 abuts against the inclined surface of the top block 63. The arc block 65 and the top column 62 move upward, lifting the processed workpiece upward. The processed workpiece is then taken out through the conveying structure 9, and the workpiece to be processed can be placed into the processing position 4 through the conveying structure 9.

[0041] The first cylinder 71 controls the movement of the cleaning brush 72 to clean the tray 3. At the same time, the brush 31 rotates to sweep the debris scattered in the retaining ring 32 into the discharge trough 73. The second cylinder 81 controls the position of the motor 5 and the tray 3, which can be moved upward to facilitate the worker to clean and remove the debris located below the tray 3.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
