Description

Technical Field

[0001] This utility model relates to the field of polishing machine technology, specifically a polishing machine with a feeding structure. Background Technology

[0002] Polishing machines use high-speed friction between polishing wheels and other components and the surface of an object to remove tiny bumps, burrs, and defects, resulting in a highly smooth surface. For example, metal products may have tool marks on their surface after processing; polishing can significantly improve the smoothness of the surface.

[0003] A round tube polishing machine is a type of polishing machine that uses the centerless grinding principle. It has two grinding wheels: a polishing wheel, which is driven by a motor to rotate at high speed, and polishing is achieved through the friction between the polishing wheel and the surface of the round tube, as well as the chemical action of the polishing agent. The other wheel is a guide wheel, which drives the workpiece to rotate and controls its feed motion. However, existing round tube polishing machines lack automatic feeding mechanisms, requiring manual feeding by operators, resulting in low work efficiency and a risk of safety accidents. Therefore, a polishing machine with a feeding structure has been proposed. Utility Model Content

[0022] 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.

[0023] This utility model provides a technical solution: such as Figures 1 to 7 As shown in this embodiment, a polishing machine with a feeding structure includes a polishing machine body 1. A fixed frame 2 is provided at the feeding end of the polishing machine body 1. A material box 3 is fixedly installed at the upper end of the fixed frame 2. A discharge chute 20 is provided on one side of the material box 3. A U-shaped plate 4 is provided below the discharge chute 20. The U-shaped plate 4 moves relative to the fixed frame 2 through a lifting mechanism. The upper surfaces of both ends of the U-shaped plate 4 are inclined downwards in the direction away from the material box 3. An intercepting plate 9 is fixedly connected to the upper surfaces of both ends of the U-shaped plate 4 on the side away from the material box 3. Guide plates 8 are provided on both sides of the U-shaped plate 4. The bottoms of the two guide plates 8 are fixedly connected to the fixed frame 2 through upright plates 7. A conveying mechanism is provided at the ends of the two guide plates 8.

[0024] The conveying mechanism consists of a first fixed base 10, a mounting plate 11, an active double-rail guide wheel 14, a first conveying rope 15, a second conveying rope 16, a second fixed base 17, and a driven double-rail guide wheel 18. The first fixed base 10 and the second fixed base 17 are respectively fixedly installed on the upper sides of the fixed frame 2. The mounting plate 11 is fixedly installed on the side wall of the first fixed base 10. The active double-rail guide wheel 14 is rotatably installed on one side wall of the mounting plate 11. A drive mechanism acting on the active double-rail guide wheel 14 is provided on the other side wall of the mounting plate 11. The driven double-rail guide wheel 18 is rotatably installed on the side wall of the second fixed base 17. The first conveying rope 15 and the second conveying rope 16 are wound around the outer surfaces of the active double-rail guide wheel 14 and the driven double-rail guide wheel 18.

[0025] The gap between the first conveyor rope 15 and the second conveyor rope 16 can center the cylindrical material. The drive mechanism can drive the driven double-rail guide wheel 18 to rotate, thereby driving the first conveyor rope 15 and the second conveyor rope 16, and then driving the material on the first conveyor rope 15 and the second conveyor rope 16 to be conveyed towards the polishing machine body 1.

[0026] The drive mechanism consists of a motor 12 and a reducer 13. Both the motor 12 and the reducer 13 are fixedly mounted on the side wall of the mounting plate 11. The output shaft of the motor 12 is fixedly connected to the input shaft of the reducer 13, and the output shaft of the reducer 13 is fixedly connected to the shaft end of the active double-rail guide wheel 14.

[0027] A guide groove 19 is provided between the conveying mechanism and the polishing machine body 1. One end of the guide groove 19 is aligned with the conveying track of the conveying mechanism, and the other end of the guide groove 19 is aligned with the processing track of the polishing machine body 1. The guide groove 19 is fixedly connected to the side wall of the polishing machine body 1.

[0028] The guide groove 19 ensures that the material is conveyed toward the processing track of the polishing machine body 1.

[0029] Among them, a baffle 21 is provided on the side of the second conveyor rope 16 away from the guide plate 8, and the baffle 21 is fixedly installed on the upper end of the fixed frame 2.

[0030] The baffle 21 can intercept the material rolling down from the guide plate 8, ensuring that the material stops between the first conveyor rope 15 and the second conveyor rope 16. At the same time, the guide plate 8 and the baffle 21 can respectively intercept the sides of the first conveyor rope 15 and the second conveyor rope 16, preventing the first conveyor rope 15 and the second conveyor rope 16 from spreading to the sides.

[0031] The lifting mechanism consists of a cylinder 5 and a fixing plate 6. The fixing plate 6 is located above the middle of the U-shaped plate 4 and is fixedly connected to the side wall of the fixing frame 2. The cylinder 5 is fixedly installed at the upper end of the fixing plate 6. The telescopic rod of the cylinder 5 slides through the fixing plate 6 and is fixedly connected to the middle of the upper end of the U-shaped plate 4.

[0032] In use, the height of the U-shaped plate 4 can be controlled by controlling the extension and retraction length of the cylinder 5 telescopic rod.

[0033] The bottom of the material box 3 is inclined downward toward the discharge chute 20.

[0034] This configuration ensures that the cylindrical material in the material box 3 rolls toward the discharge chute 20.

[0035] This utility model provides a polishing machine with a feeding structure, the specific working principle of which is as follows:

[0036] The polishing machine body 1 is model ZJ-180, which is a round tube polishing machine that uses the centerless grinding principle, a current technology. The attached diagram does not show it in detail; its working principle is briefly described below:

[0037] It has two grinding wheels: a polishing wheel, driven by a motor to rotate at high speed, which polishes the workpiece using friction between the wheel and the surface of the round tube, as well as the chemical action of the polishing agent. The other wheel is a guide wheel, which rotates the workpiece and controls its feed motion. During operation, the workpiece is placed between the polishing wheel and the guide wheel, supported by a support plate, eliminating the need for conventional clamping or centering devices. The polishing wheel rotates at a high linear velocity to polish the outer diameter of the workpiece. The guide wheel rotates at a lower speed, using friction with the workpiece to rotate it. Simultaneously, the guide wheel's axis is tilted at a small angle to the polishing wheel's axis, allowing the workpiece to feed axially while rotating, thus achieving continuous grinding.

[0038] How this application works:

[0039] Cylindrical material is placed into material box 3. The bottom of material box 3 is tilted downwards towards the discharge chute 20 to ensure that the cylindrical material inside material box 3 rolls towards the discharge chute 20. When feeding is needed, the extension rod of cylinder 5 is retracted, causing U-shaped plate 4 to move upwards. U-shaped plate 4 is located below discharge chute 20. When U-shaped plate 4 moves upwards, it lifts the bar material located at discharge chute 20 and moves the bar material upwards. When the height of the bar material is higher than material box 3, it rolls downwards along the inclined surfaces on both sides of U-shaped plate 4 and is intercepted by interceptor plate 9. At this time, the extension cylinder... The length of the telescopic rod drives the U-shaped plate 4 to move downwards. Under the action of gravity, the bar will move downwards until both ends of the bar contact the guide plate 8. When the U-shaped plate 4 moves downwards and separates from the bar, the bar will roll along the direction of the guide plate 8 to between the first conveyor rope 15 and the second conveyor rope 16. Under the action of the motor 12 and the reducer 13, the driven double-rail guide wheel 18 can be driven to rotate, thereby driving the first conveyor rope 15 and the second conveyor rope 16, and then driving the bar on the first conveyor rope 15 and the second conveyor rope 16 to be conveyed towards the polishing machine body 1, thereby completing the automatic feeding of the bar.

[0040] The extension and retraction frequency of cylinder 5 depends on the processing time of one bar stock. It is sufficient to ensure that the extension and retraction of cylinder 5 can move in time after one bar stock is processed. The timed extension and retraction of cylinder 5 can be controlled by time relay, PLC, etc., which will not be described in detail here.

[0041] It should be noted that, from a top-down view, the width of the overlapping part of the U-shaped plate 4 and the discharge chute 20 needs to be equal to the diameter of the bar stock. This setting ensures that the U-shaped plate 4 can only carry one bar stock at a time.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
