Description

Technical Field

[0001] This utility model belongs to the field of hydraulic cylinder cleaning, specifically referring to a high-efficiency cleaning device for hydraulic cylinders. Background Technology

[0002] As the actuator in a hydraulic system, the cleanliness of the inner wall of the cylinder barrel directly affects the working performance and service life of the hydraulic cylinder. During the production and maintenance of hydraulic cylinders, it is necessary to thoroughly clean the inner wall of the cylinder barrel to remove residual iron filings, oil stains, dust, and other impurities.

[0003] Currently, existing hydraulic cylinder cleaning devices have many shortcomings: First, they have poor clamping adaptability. Traditional clamping structures are mostly of fixed size, which is difficult to adapt to hydraulic cylinders of different diameters and lengths. During clamping, loosening or over-tightening is likely to occur, causing the cylinder to shift during the cleaning process and affecting the cleaning accuracy. Second, the cleaning is not comprehensive. Most cleaning devices use a fixed-direction rinsing method with a single rinsing angle, which can easily leave cleaning dead corners on the inner wall of the cylinder, especially the transition area between the two ends and the middle of the cylinder, where impurities are difficult to remove completely. Utility Model Content

[0004] The present invention mainly addresses the aforementioned technical problems.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: The high-efficiency cleaning device for hydraulic cylinders proposed by this utility model includes a base, on both sides of the upper part of the base having sliding grooves, and a mounting frame fixed in the middle of the upper part of the base. It also includes a mobile device, a clamping assembly, and a driving device.

[0006] The mobile device is located on the upper part of the base. The mobile device includes two symmetrical sliders. The sliders are slidably disposed in the slide groove, and a connecting rod is fixed between the two sets of sliders.

[0007] The clamping assembly is mounted on the mobile device and is movably connected to the upper part of the base. The clamping assembly includes two sets of symmetrical movable frames, and the connecting rod slides vertically through the two sets of movable frames.

[0008] The drive device is located in the mounting bracket on the upper part of the base, and the drive device includes a gear, which is rotatably located in the mounting bracket.

[0009] Furthermore, the mobile device also includes a first electric telescopic rod, which is disposed inside the slide groove, with its fixed end fixedly connected to the inner side of the slide groove and its movable end fixedly connected to a slider on one side.

[0010] Furthermore, the clamping assembly also includes a motor and a double-ended screw. The motor is fixed to the outside of one end of the slider, and the double-ended screw is rotatably disposed between the two sides of the slider, with one end passing through the slider and the motor shaft.

[0011] Furthermore, the threaded structures at both ends of the double-ended screw are symmetrically arranged, and both threads penetrate the movable frame perpendicularly. The adjacent surfaces of the movable frame on both sides are provided with clamping grooves, which are designed as trapezoidal groove structures.

[0012] Furthermore, a bracket is fixed to the upper part of the connecting rod, and the bracket is located between the two movable frames.

[0013] Furthermore, the driving device also includes a second electric telescopic rod and a rack. The fixed end of the second electric telescopic rod is fixed to the upper part of the base, and the movable end is fixedly connected to one end of the rack. The rack is slidably disposed inside the mounting frame. The rack and the lower part of the gear are meshed and connected. A limiting strip is fixed to the outside of the rack, and a limiting groove is opened on the inner side of the mounting frame. The limiting strip and the limiting groove are slidably fitted together.

[0014] Furthermore, one end of the gear is rotatably connected to a liquid supply pipe, and the connection adopts a bearing structure with an internal sealing strip.

[0015] Furthermore, a flushing pipe is fixedly provided on the side of the gear near the clamping assembly. The flushing pipe passes through the gear and is connected to the liquid supply pipe. Several flushing ports are evenly opened on the side of the flushing pipe.

[0016] The beneficial effects of this utility model by adopting the above structure are as follows:

[0017] 1. The high-efficiency cleaning device for hydraulic cylinders proposed in this solution uses a motor to drive a double-headed screw to rotate. The symmetrical thread structure at both ends of the double-headed screw drives two sets of moving frames to move closer or further away synchronously. Combined with the trapezoidal groove clamping slot, it can stably clamp hydraulic cylinders of different diameters, and the clamping is firm and not easy to shift.

[0018] 2. The high-efficiency cleaning device for hydraulic cylinders proposed in this solution has a second electric telescopic rod that drives the rack to move. The rack meshes with the gear, causing the gear to rotate, which in turn causes the flushing pipe to rotate with the gear. During the rotation, the flushing port on the side of the flushing pipe flushes the inner wall of the hydraulic cylinder in all directions, effectively eliminating cleaning dead corners.

[0019] 3. The high-efficiency cleaning device for hydraulic cylinders proposed in this solution uses a mobile device to drive a slider along a slide groove via a first electric telescopic rod, thereby achieving the overall transfer of the clamping assembly and the hydraulic cylinder. This allows the cylinder to be precisely moved to the flushing pipe position, and the clamping and cleaning processes are automatically connected without manual intervention, thus improving cleaning efficiency.

[0028] like Figure 1-2As shown, the clamping assembly 3 is mounted on the mobile device 2 and is movably connected to the upper part of the base 1. The clamping assembly 3 includes two sets of symmetrical movable frames 304. The connecting rod 203 slides vertically through the two sets of movable frames 304. The clamping assembly 3 also includes a motor 301 and a double-ended screw 302. The motor 301 is fixed to the outside of one end of the slider 202. The double-ended screw 302 is rotatably mounted between the two sides of the slider 202, and one end passes through the slider 202 and is shaft-connected to the motor 301. The threaded structures at both ends of the double-ended screw 302 are symmetrically arranged, and both threads pass vertically through the movable frames 304. The adjacent surfaces of the two sides of the movable frames 304 are provided with clamping grooves 305. The clamping grooves 305 are designed as trapezoidal groove structures. A bracket 303 is fixed on the upper part of the connecting rod 203. The bracket 303 is located between the two sides of the movable frames 304 to prevent the hydraulic cylinder from falling onto the upper part of the double-ended screw 302.

[0029] like Figure 1-2 As shown, the drive device 4 is located in the mounting bracket 102 on the upper part of the base 1.
