Description

Technical Field

[0001] This utility model relates to the field of polishing device technology, and in particular to a surface polishing device for a connecting rod structure. Background Technology

[0002] Connecting rod surface polishing equipment is specifically designed to improve the surface finish and precision of connecting rods. In the field of mechanical manufacturing, connecting rods, as key transmission components, directly affect the operational stability, wear resistance, and service life of mechanical systems due to their surface quality. After machining, connecting rods often have defects such as tool marks, burrs, and oxide layers. These defects not only increase frictional resistance during operation but can also cause stress concentration, reducing component strength. Therefore, the use of connecting rod surface polishing equipment is essential. In automotive engine manufacturing, aerospace precision machining, and large-scale engineering machinery assembly, the requirements for connecting rod surface quality are extremely high. Connecting rod polishing equipment can achieve ideal roughness and precision standards through fine processing, ensuring the efficient and stable operation of mechanical systems.

[0003] Existing surface polishing devices for linkage structures mostly adopt a structure of fixed grinding disc and fixed linkage with conveyor belt, and polishing is achieved by the linkage reciprocating on the grinding disc by the conveyor belt.

[0004] However, this structure has some drawbacks. The way the conveyor belt fixes the connecting rods is difficult to adapt to connecting rods of different shapes and sizes, resulting in poor versatility. Manual alignment is required during loading and unloading, which limits production efficiency. Therefore, a surface polishing device for the connecting rod structure is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a connecting rod structure surface polishing device, which aims to improve the problems of poor versatility and low production efficiency caused by the difficulty of adapting existing equipment to connecting rods of different shapes and sizes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a surface polishing device for a linkage structure, comprising a concave steel plate, on the upper surface of the concave steel plate a steel frame symmetrically arranged on both sides, a telescopic component for connecting a first steel plate is provided inside the steel frame, a fixing member is fixedly connected to the lower surface of the steel plate, a rotating wheel is rotatably connected inside the fixing member, a polishing belt is provided on the outer wall of the rotating wheel, and symmetrical slide rails are provided on both sides of the inner wall of the concave steel plate, a panel is slidably connected to the inner wall of the slide rail, and a second steel plate for connecting a clamping component is fixedly connected to the lower surface of the panel.

[0007] The clamping assembly includes a second slider, a third slide rail, and a clamping plate. The third slide rail is located below the panel. The inner wall of the second slider is slidably connected to the outer wall of the third slide rail. One side of the lower surface of the clamping plate is fixedly connected to one side of the outer wall of the second slider. The second slide rail is fixedly connected to one side of the outer wall of the third slide rail, and one end of the second slide rail is fixedly connected to one side of the outer wall of the second steel plate.

[0008] Furthermore, a crossbeam is fixedly connected inside the concave steel plate, and a positioning component is fixedly connected to the upper surface of the crossbeam for positioning the reciprocating assembly.

[0009] Furthermore, the reciprocating assembly includes a second motor, the output end of which is fixedly connected to a turntable, one end of which is rotatably connected to a first connecting rod, one end of which is rotatably connected to a driven rod, one end of which is fixedly connected to one side of the outer wall of the second steel plate, and the outer wall of the driven rod is slidably connected inside the positioning component.

[0010] Furthermore, a motor is fixedly connected to one side of the outer wall of one of the fixing members, and the output end of the motor passes through the fixing member and is fixedly connected to one end of the rotating wheel.

[0011] Furthermore, the telescopic component includes a steel pipe and a spring, with a steel shaft slidably connected inside the steel pipe, and one end of the spring fixedly connected to the upper surface of the steel pipe.

[0012] Furthermore, the upper surface of the steel pipe is fixedly connected to the inside of the steel frame, and the lower surface of the steel shaft is fixedly connected to the upper surface of the steel plate.

[0013] Furthermore, one end of the second slider is provided with a transmission component for connecting the first slider, one side of the inner wall of the first slider is slidably connected to the outer wall of the second slide rail, and a bolt connecting rod is provided inside the first slider, with a hydraulic rod fixedly connected to one end of the bolt connecting rod.

[0014] Furthermore, the transmission assembly includes a rotating shaft, one end of which is fixedly connected to the inside of a slider, and the other end of which is rotatably connected to a connecting rod, one end of which is rotatably connected to the rotating shaft, and one end of which is fixedly connected to the inside of the slider.

[0015] This utility model has the following beneficial effects:

[0016] In this invention, a hydraulic rod pushes and pulls a bolt connecting rod, causing a slider one connected to the bolt connecting rod to slide on a slide rail two. This allows the two connecting rods connected to slider one to change the direction of movement of slider two via a rotating shaft, causing slider two to slide on a slide rail three. This, in turn, causes a clamping plate connected to one side of the outer wall of slider two to slide. Through this series of actions, the distance between the two clamping plates changes. Further adjustment to a suitable distance based on the dimensions of the connecting rods allows the connecting rods to be fixed, thus improving the practicality of the device.

[0017] In this invention, the height of the rod as it passes over the polishing belt compresses the polishing belt, causing the polishing belt and the rotating wheel to push the fixing parts and the steel plate upwards. This achieves the tightening of the spring and the sliding of the steel shaft. When the height of the rod changes, the elastic force of the spring further ensures that the polishing belt always stays in contact with the rod, thus achieving uniform polishing and improving the practicality of the device.

The inner walls of the concave steel plate 1 are provided with left and right symmetrical slide rails 11. A panel 12 is slidably connected to the inner wall of the slide rails 11. A steel plate 13 is fixedly connected to the lower surface of the panel 12 for connecting the clamping assembly.

[0027] The clamping assembly includes a second slider 18, a third slide rail 19, and a clamping plate 20. The inner wall of the second slider 18 is slidably connected to the outer wall of the third slide rail 19. The upper surface of the third slide rail 19 is located below the panel 12. One side of the outer wall of the clamping plate 20 is fixedly connected to one side of the outer wall of the second slider 18. One side of the outer wall of the third slide rail 19 is fixedly connected to a second slide rail 17. One end of the second slide rail 17 is fixedly connected to one side of the outer wall of the second steel plate 13.

[0028] Reference Figure 2 The telescopic assembly includes a steel pipe 3 and a spring 5. A steel shaft 4 is slidably connected inside the steel pipe 3. One end of the spring 5 is fixedly connected to the upper surface of the steel pipe 3. The upper surface of the steel pipe 3 is fixedly connected to the inside of the steel frame 2. The lower surface of the steel shaft 4 is fixedly connected to the upper surface of the steel plate 6. The steel pipe 3 is used to connect the steel frame 2 and other components in the telescopic assembly, and receives changes in the steel shaft 4. The spring 5 will contract when compressed. The spring 5 and the steel shaft 4 work together to change the height of the main polishing structure.

[0029] Reference Figure 4One end of slider 18 is provided with a transmission assembly for connecting slider 16. The inner wall of slider 16 is slidably connected to the outer wall of slide rail 17. A bolt connecting rod 15 is provided inside slider 16, and one end of the bolt connecting rod 15 is fixedly connected to a hydraulic rod 14. The hydraulic rod 14 provides power to the clamping device. The transmission assembly includes a rotating shaft 27, one end of which is fixedly connected to slider 16, and the other end of which is rotatably connected to a connecting rod 28. The rotating shaft 27 connects slider 16 and connecting rod 28, enabling the connecting rod to move. Rod 28 can rotate freely without other constraints. One end of rod 28 is rotatably connected to shaft 29. One end of shaft 29 is fixedly connected to slider 18. Shaft 29 is used to connect rod 28 and slider 18, allowing rod 28 to rotate freely without other constraints. Rod 28 is used to connect slider 16 and slider 18 and change the direction of the force transmitted by hydraulic rod 14. Through the above connection and power transmission, the distance between the two clamping plates 20 can be changed, thereby fixing the rod for subsequent polishing.

[0030] Reference Figure 5 The reciprocating assembly includes a second motor 23, which provides power and speed. A turntable 24 is fixedly connected to the output end of the second motor 23.

The turntable 24 and the connecting rod 25 can transmit kinetic energy to the driven rod 26 and change the motion trajectory of the driven rod 26.

[0031] Working principle: When the device is needed to polish the connecting rod structure, first turn on the power to start the motor 10. The motor 10 starts to run, driving the rotating wheel 8 and the polishing belt 9 to rotate. When the rod passes the polishing belt 9, the spring 5 will contract to make the polishing belt 9 come into close contact with the rod. The abrasive particles on the surface of the polishing belt 9 come into contact with the surface of the connecting rod. Since the hardness of the abrasive particles is greater than the hardness of the connecting rod material, under the action of pressure and relative motion, the abrasive particles will cut the tiny protrusions on the surface of the connecting rod, gradually grinding them flat, and at the same time removing burrs, oxide scale and other impurities from the surface, thereby achieving the polishing effect.

[0032] Secondly, the connecting rod structure to be polished is fixed using a clamping device. The connecting rod is first placed on the panel 12. The hydraulic rod 14 drives the bolt connecting rod 15, which in turn drives the slider 16 to slide on the slide rail 17. The slider 16 then drives the connecting rod 28 to pull or push the slider 28 to slide on the slide rail 19. The slider 28 then pushes or pulls the clamping plate 20 through its sliding motion. Through a series of power transmissions, the distance between the two clamping plates 20 is changed, thereby fixing the connecting rod to be polished. The motor 23 then drives the turntable 24, the connecting rod 1 25, and the driven rod 26. The driven rod 26 drives the panel 12 and the clamping device to reciprocate, causing the fixed connecting rod to pass through the rotating polishing belt 9, thus achieving the polishing work.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
