Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder component processing technology, and in particular, to a hydraulic cylinder barrel cleaning device. Background Technology

[0002] The cylinder barrel is the main body of a hydraulic cylinder, and its primary function is to withstand hydraulic pressure and form a sealed working volume. The cylinder barrel is typically made of a metal material with sufficient strength and rigidity to withstand high-pressure working environments. The machining quality of the cylinder barrel directly affects the reliability and service life of the hydraulic cylinder. After the initial machining of the cylinder barrel, to prevent dust and other impurities inside the cylinder barrel from adversely affecting the cleanliness of the hydraulic oil, it is usually necessary to clean the inner wall of the cylinder barrel.

Spray nozzles are evenly fixedly mounted on the outer side of the cleaning pipe, strip brushes are symmetrically fixedly mounted on the outer side of the cleaning pipe, and an arc-shaped brush is fixedly mounted on the bottom of the cleaning pipe. During operation, the drive mechanism drives the cleaning pipe to rotate, thereby driving the strip brushes and arc-shaped brushes to clean the inner wall of the cylinder barrel. However, in actual work, the above-mentioned cleaning device can only be used for cleaning cylinder barrels with the same inner diameter, resulting in significant limitations and low versatility, greatly reducing the user experience.

[0020] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] Please see 1- Figure 4This utility model provides a hydraulic cylinder barrel cleaning device, including a base 1, a support plate 2, a fixing component 3, a lifting component 4, and a cleaning component 5. The support plate 2 is vertically fixed on the base 1. The fixing component 3 is installed on the base 1 to fix the cylinder barrel 100 to be cleaned. The lifting component 4 is installed on the support plate 2 to drive the cleaning component 5 to move longitudinally within the cylinder barrel 100. The cleaning component 5 includes a drive motor 51, a rotating column 52, and a cleaning structure 53. The rotating column 53 is fixedly connected to the output shaft of the drive motor 51. The cleaning structure 53 includes two parallel connecting rods 531 and a cleaning rod 532 hinged to the ends of the two connecting rods 531. The two connecting rods 531 are arranged vertically along the longitudinal direction. The end of the connecting rod 531 away from the cleaning rod 532 is hinged to the rotating column 52. The cleaning rod 532 is parallel to the rotating column 52. A cleaning cloth 533 is provided on the cleaning rod 532.

[0022] When using the hydraulic cylinder cleaning device of this utility model, the cylinder 100 to be cleaned is placed on the base 1 and fixed by the fixing component 3. At this time, the cylinder 100 is directly below the cleaning structure 53. Then, the lifting assembly 4 is activated, driving the cleaning assembly 5 to move downwards and sending the cleaning structure 53 into the cylinder 100. At this time, the drive motor 51 is activated, driving the rotating column 52 and the cleaning structure 53 to rotate at high speed. At this time, in the parallel four-bar linkage structure composed of two connecting rods 531, the cleaning rod 532 and the rotating column 52, the cleaning rod 532 will expand outwards under the action of centrifugal force, so that the cleaning cloth 533 is tightly pressed against the inner wall of the cylinder 100. Under the action of the drive motor 51, the cleaning cloth 533 can rotate along the circumference of the cylinder 100, thereby cleaning the inner wall of the cylinder 100. At the same time, under the action of the lifting assembly 4, the cleaning cloth 533 can move along the axial direction of the cylinder 100, thereby thoroughly cleaning all parts along the axial direction on the inner wall of the cylinder 100.

[0023] Compared to traditional cylinder cleaning devices, the cleaning structure 53 in this invention can expand and deform outward under centrifugal force, thereby allowing the cleaning cloth 533 to adhere to the inner wall of the cylinder 100. The cleaning cloth 533 can adaptively adhere to the cylinder 100 according to its inner diameter and perform cleaning. The same cleaning device can achieve cleaning of cylinders 100 with different inner diameters, making it widely applicable and greatly improving the user experience.

[0024] In a preferred embodiment, the rotating column 52 has a cylindrical structure, and a limiting edge 521 extends radially outward from the bottom of the rotating column 52. The limiting edge 521 can abut against the connecting rod 531 located below. When the cleaning structure 53 has not yet extended into the cylinder 100, under the action of gravity, the connecting rod 531 rests against the limiting edge 521, and the limiting edge 521 supports the connecting rod 531, effectively preventing the connecting rod 531 from tilting downward. Thus, when the cleaning structure 53 extends into the cylinder 100, the connecting rod 531 tilts upward. At this time, part of the gravity component of the cleaning rod 532 and the cleaning cloth 533 will act on the inner wall of the cylinder 100, thereby promoting the tight abutment between the cleaning cloth 533 and the inner wall of the cylinder 100 and improving the cleaning effect on the inner wall of the cylinder 100.

[0025] The rotating column 52 is coaxially arranged with the cylinder 100 to be cleaned. In this embodiment, there are two cleaning structures 53, which are symmetrically arranged on opposite sides of the rotating column 52. During operation, the two cleaning structures 53 clean the inner wall of the cylinder 100 at the same time, which greatly improves the cleaning effect.

[0026] Furthermore, a groove 522 is provided axially on the side wall of the rotating column 52, and a pin 523 is installed in the groove 522. The end of the connecting rod 531 is rotatably sleeved on the outside of the pin 523.

[0027] In this embodiment, the cleaning cloth 533 is fixedly mounted on the side of the cleaning rod 532 away from the rotating column 53, and a counterweight 534 is fixedly installed on the side of the cleaning rod 532 away from the cleaning cloth 533. By setting the counterweight 534, the weight of the cleaning structure 53 is increased, thereby increasing the centrifugal force experienced by the cleaning structure 53 when it rotates, further improving the cleaning effect on the inner wall of the cylinder 100.

[0028] In this embodiment, the fixing component 3 includes two opposing abutment blocks 31, which are symmetrically arranged about the rotating column 52. The two abutment blocks 31 can be spaced apart or close together. The cylinder 100 is sleeved on the outside of the two abutment blocks 31, and the two abutment blocks 31 abut against the opposite sides of the inner wall of the cylinder 100, thereby pressing the cylinder 100 tightly onto the base 1. Preferably, the surfaces of the two abutment blocks 31 that are spaced apart are arc-shaped surfaces. These arc-shaped surfaces are used to abut against the inner wall of the cylinder 100. In use, the arc-shaped surfaces abut against the inner wall of the cylinder 100, which can prevent the abutment blocks 31 from excessively wearing the cylinder 100, thereby ensuring the machining quality of the cylinder 100.

[0029] The fixing assembly 3 also includes a lead screw 32 and a lead screw motor 33. Specifically, a groove 11 is provided on the upper surface of the base 1, and the abutment 31 is slidably engaged with the groove 11, so that the abutment 31 can only slide along the groove 11 and cannot rotate relative to the base 1. The lead screw 32 is rotatably mounted on the base 1 and extends into the groove 11. The lead screw motor 33 is mounted on the side wall of the base 1, and the lead screw 32 is fixedly connected to the output shaft of the lead screw motor 33. The lead screw 32 is a bidirectional lead screw, that is, the lead screw 32 has threaded sections with opposite thread directions, and is threadedly connected to the two abutment blocks 31 respectively. Thus, when the lead screw motor 33 rotates, it drives the lead screw 32 to rotate, which can further drive the two abutment blocks 31 to move synchronously to clamp or release the cylinder 100.

[0030] In other embodiments, the fixing component 3 can also be configured as a clamp structure, which is fixedly sleeved on the outside of the cleaning cylinder 100. In this case, the components on the fixing component 3 do not contact the inner wall of the cylinder 100, thereby facilitating the cleaning of the entire inner wall of the cylinder 100. Furthermore, after the cylinder 100 is fixed by the clamp structure, it is in a suspended state, thereby facilitating the cleaning cloth 533 to reach the bottom of the inner wall of the cylinder 100.

[0031] In this embodiment, the lifting assembly 4 includes a lifting motor 41, a screw 42, and a slider 43. The slider 43 is slidably mounted on the support plate 2 along the longitudinal direction. The slider 43 can only slide relative to the support plate 2 and cannot rotate relative to it. The screw 42 passes through the slider 43 and is threadedly connected to it. The lifting motor 42 is fixedly connected to the support plate 2, and the screw 42 is fixedly connected to the output shaft of the lifting motor 41. The drive motor 51 is fixedly connected to the slider 43. Thus, when the lifting motor 41 is started, it can drive the screw 42 to rotate, thereby driving the slider 43 and the lifting motor 41 to move longitudinally. In other embodiments, the lifting assembly 4 can also be a cylinder. In this case, the cleaning assembly 5 is directly driven by the cylinder to move longitudinally. For example, the cylinder can be fixedly mounted on the support plate 2, and the drive motor of the cleaning assembly 5 can be mounted on the extended end of the cylinder. The method of driving the cleaning assembly 5 to move longitudinally is not limited here.

[0032] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
