Technical Field

[0001] The invention relates to the technical field of polishing devices, in particular to a polishing device for processing the inner wall of a hydraulic element. Background Art

[0002] Hydraulic components, particularly hydraulic cylinders and hydraulic oil cylinders, play a vital role in industry. They convert hydraulic energy into mechanical energy, achieving linear reciprocating or oscillating motion. The smoothness of the cylinder barrel's inner wall directly impacts the smoothness of the piston rod's movement. Therefore, inner wall polishing is a key process for improving hydraulic cylinder performance.

[0003] Traditional hydraulic cylinder inner wall polishing methods can suffer from issues such as a single structure, limited applicability, and uneven polishing. These issues limit production efficiency and product quality. With technological advancements, a variety of hydraulic cylinder inner wall polishing devices have emerged on the market, aiming to address these issues and improve polishing flexibility and efficiency.

One end of the hydraulic element is inserted into the filtering unit.

[0007] The base serves as the installation basis, the pushing unit is responsible for driving the sliding of the grinding unit, and the clamping unit is responsible for fixing the hydraulic component. After the hydraulic component is fixed, the grinding unit grinds the inner wall of the hydraulic component from the other end of the hydraulic component. The grinding unit can grind the hydraulic components at both ends at the same time, which improves the grinding efficiency and reduces the equipment cost. The filtering unit sucks in the grinding debris in the hydraulic component for filtering and storage, protecting the workshop environment and the health of the operator.

[0008] Furthermore, the pushing unit includes a slide, a connecting plate and a three-phase asynchronous motor, the slide and the base are slidingly connected, the slide and the three-phase asynchronous motor are transmission-connected, the three-phase asynchronous motor and the rear end face of the base are fixedly connected, a slide groove is provided on the slide, the connecting plate is located at both ends of the slide, the connecting plate and the slide are slidingly connected through the slide groove, and a grinding unit is provided on the connecting plate.

[0009] The three-phase asynchronous motor provides power for the slide to slide on the base. The connecting plate slides on the slide to adjust the distance between the internal components of the grinding unit. It can also control the distance between the grinding unit and the hydraulic components, laying the foundation for the grinding unit to grind the hydraulic components on both sides of the base at the same time.

[0010] Furthermore, the skateboard is provided with fixing grooves at both ends parallel to the slide groove, and limiting nuts are provided in the fixing grooves at both ends of the skateboard. The limiting nuts can move in the fixing grooves, and the limiting nuts are threadedly connected to the limiting studs. One end of the limiting studs clamps the connecting plate outside the fixing groove.

[0011] The limiting nut and the limiting stud can be tightened when the connecting plate moves to a specified position to fix the connecting plate, thereby achieving the effect of controlling the distance between the grinding unit and the hydraulic element.

[0012] Furthermore, the grinding unit includes a grinding motor, a spindle box, a grinding spindle and a grinding head. The grinding motor is placed at one end of the connecting plate, the grinding motor and one end of the spindle box are fixedly connected, the spindle box and the connecting plate are fixedly connected, one end of the grinding spindle passes through the spindle box, the grinding spindle passes through one end of the spindle box and is transmission-connected to the grinding motor, and the other end of the grinding spindle is fixedly connected to the grinding head.

[0013] The grinding motor provides power for the grinding spindle to rotate. The spindle box is used to fix the position of the grinding spindle. The spindle box is connected to the connecting plate, and the distance between the grinding head and the hydraulic component can be adjusted. The grinding head is connected to the grinding spindle to grind the inner wall of the hydraulic component.

[0015] When clamping the hydraulic component, first connect one end of the hydraulic component to the filter unit, then turn the handwheel to drive the slider to move. The combined slider clamps and positions the hydraulic component. The four sliders clamp both ends of the hydraulic component, which is more stable and makes the axis of the hydraulic component consistent with the axis of the grinding head and grinding spindle, ensuring normal grinding.

[0016] Furthermore, the filter unit includes an exhaust fan, a shell, a filter, a filter box, a connecting pipe and an exhaust pipe. The shell is arranged at both ends of the base, one end of the connecting pipe is fixedly connected to the inner wall surface of the shell facing one end of the clamping unit, the axis of the connecting pipe is consistent with the axis of the clamped hydraulic element, one end of the hydraulic element is inserted into the shell, and the other end of the connecting pipe is inserted into the filter box.

[0017] When the polishing device is running, the exhaust fan runs, forming an air duct from hydraulic element to connecting pipe, filter box, exhaust pipe, and exhaust fan outlet. The airflow in the air duct sucks the debris generated when the inner wall of the hydraulic element is polished into the filter box through the connecting pipe, and then filters it through the filter net to store the debris in the filter box.

[0018] Furthermore, the two connecting plates are provided with ends of the grinding motors staggered with each other.

[0019] The ends of the two connecting plates provided with the polishing motors are staggered with each other, which can save materials, shorten the length of the polishing device and reduce the floor space.

[0021] The transparent plastic side panel on the same side allows the operator to visually observe the accumulation of debris in the filter box, so that they can clean it according to the situation and ensure the normal operation of the equipment.

[0022] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: before grinding, the present invention first connects one end of the hydraulic component to the connecting pipe, then rotates the hand wheel to drive the movement of the slider to clamp and fix the hydraulic component, and adjusts the positions of the two connecting plates on the slide, thereby controlling the distance between the grinding head and the hydraulic component, ensuring that the grinding head can grind the hydraulic components at both ends at the same time, and then starts the polishing device to grind the inner wall of the hydraulic component. The debris generated by grinding is sucked into the filter box by the exhaust fan, and then filtered through the filter screen. The debris is stored in the filter box and regularly cleaned by observing through the transparent plastic side panel. This polishing device improves grinding efficiency, reduces equipment costs, and protects the workshop environment and the health of the operator. BRIEF DESCRIPTION OF THE DRAWINGS

The clamping unit 4 is located between the filtering unit 5 and the grinding unit 3. The hydraulic element 6 is clamped by the clamping unit 4. One end of the hydraulic element 6 is inserted into the filtering unit 5.

[0034] The base 1 serves as the installation basis, the pushing unit 2 is responsible for driving the sliding of the grinding unit 3, and the clamping unit 4 is responsible for fixing the hydraulic element 6. After the hydraulic element 6 is fixed, the grinding unit 3 grinds the inner wall of the hydraulic element 6 from the other end of the hydraulic element 6. The grinding unit 3 can grind the hydraulic elements 6 at both ends at the same time, which improves the grinding efficiency and reduces the equipment cost. The filtering unit 5 sucks in the grinding debris in the hydraulic element 6 for filtering and storage, thereby protecting the environment of the workshop and the health of the operator.

[0035] like Figure 5 As shown, the pushing unit 2 includes a slide 21, a connecting plate 22 and a three-phase asynchronous motor 23. The slide 21 is slidably connected to the base 1, and the slide 21 is transmission-connected to the three-phase asynchronous motor 23. The three-phase asynchronous motor 23 is fixedly connected to the rear end face of the base 1.

The connecting plate 22 and the slide 21 are slidably connected through the slide groove, and the grinding unit 3 is provided on the connecting plate 22.

[0036] The three-phase asynchronous motor 23 provides power for the slide plate 21 to slide on the base 1. The connecting plate 22 slides on the slide plate 21, which can adjust the distance between the internal components of the grinding unit 3. It can also control the distance between the grinding unit 3 and the hydraulic element 6, laying the foundation for the grinding unit 3 to grind the hydraulic elements 6 on both sides of the base 1 at the same time.

[0037] like Figure 5 As shown, the slide plate 21 is also provided with fixed grooves at both ends parallel to the slide groove, and limiting nuts 211 are provided in the fixing grooves at both ends of the slide plate 21.

[0040] The grinding motor 31 provides power for the rotation of the grinding spindle 33. The spindle box 32 is used to fix the position of the grinding spindle 33. The spindle box 32 is connected to the connecting plate 22. The distance between the grinding head 34 and the hydraulic element 6 can be adjusted. The grinding head 34 is connected to the grinding spindle 33 to grind the inner wall of the hydraulic element 6.

[0041] like Figure 1 and Figure 2 As shown, the clamping unit 4 includes a handwheel 41, a slider 42 and a clamping platform 43, the clamping platform 43 is fixedly connected to the base 1, the clamping platform 43 is arranged between the slide plate 21 and the filter unit 5, and a slide groove is provided on the clamping platform 43. The four sliders 42 and the clamping platform 43 are slidably connected through the slide groove. Two sliders 42 are provided at each end of the clamping platform 43, and the two sliders 42 at the same end of the clamping platform 43 are composed of a circular notch that can clamp the hydraulic element 6. The axis of the center of the circular notch composed of the sliders 42 is consistent with the axis of the grinding head 34 and the grinding spindle 33. The four sliders 42 are all connected to the handwheel 41 in a transmission manner.

[0042] When clamping the hydraulic element 6, first connect one end of the hydraulic element 6 to the filter unit 5, then rotate the handwheel 41 to drive the slider 42 to move, and the combined slider 42 clamps and positions the hydraulic element 6. The four sliders 42 clamp the two ends of the hydraulic element 6 more firmly, so that the axis of the hydraulic element 6 is consistent with the axis of the grinding head 34 and the grinding spindle 33, ensuring normal grinding.

[0043] like Figure 1 、 Figure 3 As shown, the filter unit 5 includes an exhaust fan 51, a shell 52, a filter screen 53, a filter box 54, a connecting pipe 55 and an exhaust pipe 56. The shell 52 is arranged at both ends of the base 1, and one end of the connecting pipe 55 is fixedly connected to the inner wall surface of the shell 52 facing one end of the clamping unit 4. The axis of the connecting pipe 55 is consistent with the axis of the clamped hydraulic element 6. One end of the hydraulic element 6 is inserted into the shell 52, and the other end of the connecting pipe 55 is inserted into the filter box 54. The exhaust fan 51 is arranged on the upper end surface of the shell 52, and one end of the exhaust pipe 56 passes through the upper end surface of the shell 52 and is connected to the air inlet of the exhaust fan 51.

[0044] When the polishing device is running, the exhaust fan 51 runs, forming an air duct from the hydraulic element 6 to the connecting pipe 55 to the filter box 54, the exhaust pipe 56 to the outlet end of the exhaust fan 51. The airflow in the air duct draws the debris generated when the inner wall of the hydraulic element 6 is polished into the filter box 54 through the connecting pipe 55, and then is filtered through the filter net 53 to store the debris in the filter box 54.

[0045] like Figure 1 As shown, the ends of the two connecting plates 22 provided with the grinding motors 31 are staggered with each other.

[0046] The ends of the two connecting plates 22 where the polishing motors 31 are provided are staggered with each other, which can save materials, shorten the length of the polishing device, and reduce the floor space.

[0047] like Figure 4 As shown, the side panels on the same front side of the housing 52 and the filter box 54 are made of transparent plastic panels.

[0049] The working principle of the present invention is as follows: before the polishing device is used for grinding, one end of the hydraulic element 6 is first connected to the connecting pipe 55, and then the hand wheel 41 is rotated to drive the movement of the slider 42 to clamp and fix the hydraulic element 6, and the positions of the two connecting plates 22 on the slide 21 are adjusted to control the distance between the grinding head 34 and the hydraulic element 6, so as to ensure that the grinding head 34 can grind the hydraulic elements 6 at both ends at the same time, and then the polishing device is started to grind the inner wall of the hydraulic element 6. The debris generated by grinding is sucked into the filter box 54 by the exhaust fan 51, and then filtered through the filter screen 53, and the debris is stored in the filter box 54, and is regularly cleaned by observing through the transparent plastic side panel. The present polishing device improves the grinding efficiency, reduces the equipment cost, and protects the environment of the workshop and the health of the operator.
