Description

Technical Field

[0001] This application relates to the field of metal polishing technology, and more particularly to a metal polishing apparatus. Background Technology

[0002] After manufacturing, metal products often have defects such as burrs, scratches, oxide layers, and machining marks on their surfaces. These defects not only affect the product's aesthetic appearance but can also reduce its corrosion resistance, fatigue strength, fit accuracy, and the adhesion of subsequent coatings or electroplating. Polishing, as a key process in metal surface treatment, aims to remove these surface defects and obtain a smooth, flat, bright surface, or even a surface with specific textures, to meet the needs of different applications.

[0003] However, existing metal polishing devices have the following drawbacks: for example, the stability of the polishing belt in existing devices mainly depends on the support of the raised part in the middle of the roller. The polishing process is relatively stable when the workpiece is fed in the direction of the polishing belt. However, in actual use, the polishing length of some workpieces on the side is relatively long, and the workpiece needs to be slid laterally along the polishing belt. This can easily cause the polishing belt to detach, creating a safety hazard. Summary of the Invention

[0004] The purpose of this application is to provide a metal polishing apparatus that can polish the side of a workpiece in two ways: feeding the workpiece directly in the direction of the polishing belt and sliding the workpiece laterally.

[0005] To achieve the above objectives, this application provides a metal polishing apparatus, which includes: a belt polishing assembly and a multi-functional operating table fixedly installed with the belt polishing assembly.

[0006] The multi-functional operating table includes a carriage, one end of which is fixedly installed to a belt polishing assembly. The other end of the carriage, directly in front of the polishing belt of the belt polishing assembly, is fixedly connected to a sliding plate. A frame is slidably mounted on the sliding plate along the direction opposite to the polishing belt of the belt polishing assembly, and a spring is installed between the frame and the carriage. A limiting block is fixedly connected to the side of the frame facing the polishing belt of the belt polishing assembly. A locking assembly is provided between the frame and the sliding plate. A roller is rotatably mounted on the top of the frame, with the axis of the roller perpendicular to the polishing direction of the belt polishing assembly. The belt and frame are used to support the workpiece. The operator can push the workpiece directly in the direction of the polishing belt of the belt polishing assembly. The frame and the workpiece move together toward the polishing belt of the belt polishing assembly to complete the polishing. Another way to use it is to move the frame close to the polishing belt of the belt polishing assembly. The limiting blocks are located on both sides of the polishing belt of the belt polishing assembly, and the frame and the slide plate are fixed by the locking components. The workpiece is on the top of the frame and slides laterally under the guidance of the roller. The limiting blocks restrict the polishing belt of the belt polishing assembly so that the polishing belt of the belt polishing assembly will not fall off during the operation.

[0007] In a further preferred embodiment, a guide rod is fixedly connected to the side of the trailer, and a guide plate is fixedly connected to the inner side of the frame. The guide plate and the guide rod are slidably engaged, thereby stabilizing the sliding between the frame and the trailer.

[0008] As a preferred embodiment, the locking assembly includes a locking plate fixedly connected to the guide plate, and a locking screw is provided between the locking plate and the carriage. The locking screw has a simple structure, is easy to adjust, and can realize the fixing and unlocking of the frame and the carriage.

[0009] As another preferred embodiment, the belt polishing assembly includes a support base, a main frame plate, a motor, a main roller, a transverse frame, working rollers, a tensioning wheel assembly, and a polishing belt.

[0010] A main frame plate is fixedly installed on the top of the support base. A motor is fixedly installed on one side of the main frame plate, and the output end of the motor passes through the main frame plate. A main roller is fixedly installed on the output end of the motor and on the other side of the main frame plate. A horizontal frame is fixedly installed with the main frame plate. A first side frame and a second side frame, which are symmetrically distributed, are fixedly connected to the end of the horizontal frame away from the main frame plate. Working rollers are rotatably installed on the first side frame and the second side frame. A tension wheel assembly is installed on one side of the main frame plate. A polishing belt is installed on the outside of the main roller, the two working rollers, and the tension wheel assembly. The motor drives the main roller, which in turn drives the polishing belt installed on the outside of the main roller, the two working rollers, and the tension wheel assembly. The rotating polishing belt performs polishing operations on the workpiece.

[0011] Further preferably, the tensioning wheel assembly includes a swing frame, a tensioning roller, and an elastic support.

[0012] One end of the swing frame is rotatably mounted to the main frame plate, and the other end of the swing frame is rotatably mounted with a tensioning roller. One end of the elastic support is hinged to the swing frame, and the other end of the elastic support is hinged to the main frame plate. The swing frame, the elastic support, and the main frame plate are arranged in a triangle. The tensioning roller assembly is used to keep the polishing belt in a taut state to prevent the polishing belt from loosening or falling off.

[0013] Further optimization involves the design of an inner support frame, which is fixedly installed on the side of the transverse frame. The inner support frame is located inside the polishing belt and is used to support the inner side of the polishing belt. In the working position of the polishing belt, it can effectively limit the polishing belt from being squeezed by the workpiece.

[0014] In a further preferred embodiment, the inner support frame includes an L-shaped frame, the first side plate of the L-shaped frame is fixedly installed with the transverse frame, and the second side plate of the L-shaped frame is fixedly installed with a wear-resistant plate. The wear-resistant plate can protect the polishing belt and reduce the wear between the polishing belt and the wear-resistant plate.

[0015] Further preferably, two limiting blocks are provided, with the two limiting blocks located on both sides of the polishing belt, to limit the lateral offset of the polishing belt.

[0016] Compared with the prior art, the beneficial effects of this application are as follows:

[0017] (1) In this application, a multi-functional operating table is designed to assist the workpiece in moving towards the belt polishing assembly or sliding the workpiece laterally, making the polishing process simpler for the operator. Specifically, the operator can push the workpiece directly towards the polishing belt of the belt polishing assembly, and the frame and the workpiece together move towards the polishing belt of the belt polishing assembly to complete the polishing. Another way to use it is to move the frame close to the polishing belt of the belt polishing assembly, with the limiting blocks located on both sides of the polishing belt of the belt polishing assembly, and use the locking assembly to fix the frame and the slide plate. The workpiece is on the top of the frame and slides laterally under the guidance of the roller. The limiting blocks restrict the polishing belt of the belt polishing assembly so that the polishing belt of the belt polishing assembly will not fall off during the operation.

[0027] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0028] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0029] like Figure 1-6 The metal polishing apparatus shown includes a belt polishing assembly and a multi-functional operating table fixedly installed with the belt polishing assembly. The multi-functional operating table is used to assist the workpiece in moving towards the belt polishing assembly or sliding the workpiece laterally, making the polishing process simpler for the operator.

[0030] Specifically: The multi-functional operating table includes a bracket 12. One end of the bracket 12 is fixedly installed to the belt polishing assembly. The other end of the bracket 12, located directly in front of the polishing belt 11 of the belt polishing assembly, is fixedly connected to a sliding plate 14. A frame 15 is slidably installed on the sliding plate 14 along the direction directly opposite to the polishing belt 11 of the belt polishing assembly. The frame 15 has a shell structure with its bottom end close to the opening. The frame 15 is fastened to the sliding plate 14, and a spring 18 is installed between the frame 15 and the bracket 12. The elastic force of the spring 18 causes the frame 15 to slide away from the polishing belt 11 of the belt polishing assembly. A limiting block 22 is fixedly connected to the side of the frame 15 facing the polishing belt 11 of the belt polishing assembly. The limiting block 22 restricts the left and right movement of the polishing belt 11 of the belt polishing assembly when the frame 15 approaches the polishing belt 11. A locking component is provided between the frame 15 and the sliding plate 14 to fix the frame 15 and the sliding plate 14 together. In this case, spring 18 cannot function. Roller 21 is rotatably mounted on the top of frame 15. The axis of roller 21 is perpendicular to the polishing belt 11 of the belt polishing assembly. Along the rolling direction of roller 21, the workpiece can slide smoothly. Along the direction perpendicular to the rolling direction of roller 21, the workpiece needs to move together with frame 15. Frame 15 is used to support the workpiece. The operator can push the workpiece directly in the direction of polishing belt 11 of belt polishing assembly. Frame 15 and workpiece together move towards polishing belt 11 of belt polishing assembly to complete polishing. Another way to use it is to move frame 15 close to polishing belt 11 of belt polishing assembly. Limiting blocks 22 are located on both sides of polishing belt 11 of belt polishing assembly, and locking components are used to fix frame 15 and slide plate 14. The workpiece is on top of frame 15 and slides laterally under the guidance of roller 21. Limiting blocks 22 limit polishing belt 11 of belt polishing assembly so that polishing belt 11 of belt polishing assembly does not fall off during operation.

[0031] In this embodiment, a guide rod 16 is fixedly connected to the side of the trailer 12, and a guide plate 17 is fixedly connected to the inner side of the frame 15. The guide plate 17 is slidably engaged with the guide rod 16. The guide plate 17 can be fixedly connected to the frame 15 through a cylindrical hollow part, which can stabilize the sliding between the frame 15 and the trailer 12.

[0032] The locking assembly includes a locking plate 19 fixedly connected to the guide plate 17. A locking screw 20 is provided between the locking plate 19 and the slide portion 14. The locking screw 20 has a simple structure and is easy to adjust, enabling the fixing and unlocking of the frame 15 and the slide 12. Specifically, the locking screw 20 is threadedly connected to the slide portion 14, and the locking plate 19 has a sliding hole. When the locking screw 20 is not tightened, both the locking plate 19 and the guide plate 17 can slide relative to the slide portion 14; when the locking screw 20 is tightened, the locking plate 19 and the slide portion 14 are fixed together.

[0033] In this embodiment, the belt polishing assembly includes a support base 1, a main frame plate 2, a motor 23, a main roller 3, a horizontal frame 7, a working roller 10, a tensioning wheel assembly, and a polishing belt 11. The main frame plate 2 is fixedly installed on the top of the support base 1. A motor 23 is fixedly installed on one side of the main frame plate 2. The output end of the motor 23 passes through the main frame plate 2. A main roller 3 is fixedly installed on the other side of the main frame plate 2 at the output end of the motor 23. The motor 23 is used to drive the main roller 3 to rotate. A horizontal frame 7 is fixedly installed with the main frame plate 2. A first side frame 8 and a second side frame 9, which are symmetrically distributed, are fixedly connected to the end of the horizontal frame 7 away from the main frame plate 2. Working rollers 10 are rotatably installed on the first side frame 8 and the second side frame 9. The area between the two working rollers 10 is the polishing work area. A tension wheel assembly is installed on one side of the main frame plate 2. A polishing belt 11 is installed on the outside of the main roller 3, the two working rollers 10, and the tension wheel assembly. The outside of the polishing belt 11 is the polishing surface. The motor 23 drives the main roller 3, and in turn drives the polishing belt 11 installed on the outside of the main roller 3, the two working rollers 10, and the tension wheel assembly. The rotating polishing belt 11 realizes the polishing operation of the workpiece.

[0034] In this embodiment, the tensioning wheel assembly includes a swing frame 6, a tensioning roller 5, and an elastic support 4. One end of the swing frame 6 is rotatably mounted to the main frame plate 2, and the other end of the swing frame 6 is rotatably mounted with the tensioning roller 5. One end of the elastic support 4 is hinged to the swing frame 6, and the other end of the elastic support 4 is hinged to the main frame plate 2. The swing frame 6, the elastic support 4, and the main frame plate 2 are arranged in a triangular pattern. The tensioning wheel assembly is used to keep the polishing belt 11 in a taut state and prevent the polishing belt 11 from loosening or falling off.

[0035] The elastic support 4 drives the swing frame 6 to rotate upward, that is, the tension roller 5 at the top of the swing frame 6 has a tendency to move elastically outward. The tension roller 5 presses against the inner side of the polishing belt 11, so that the polishing belt 11 is in a tensioned state.

[0036] In this embodiment, an inner support frame 13 is also designed. The inner support frame 13 is fixedly installed on the side of the horizontal frame 7. The inner support frame 13 is located inside the polishing belt 11. The inner support frame 13 is used to support the inner side of the polishing belt 11. In the working position of the polishing belt 11, it can effectively limit the polishing belt 11 from being squeezed by the workpiece.

[0037] Specifically: the inner support frame 13 includes an L-shaped frame 1301. The first side plate of the L-shaped frame 1301 is fixedly installed with the transverse frame 7. A wear-resistant plate 1302 is fixedly installed on the second side plate of the L-shaped frame 1301. The wear-resistant plate 1302 can protect the polishing belt 11 and reduce the wear between the polishing belt 11 and the wear-resistant plate 1302. In addition, two limiting blocks 22 are provided, which are located on both sides of the polishing belt 11 to limit the lateral displacement of the polishing belt 11.
