Description
Technical Field
[0001] The utility model relates to the technical field of hydraulic cylinder barrel cleaning, in particular to a hydraulic cylinder barrel cleaning device. Background Art
[0002] The cylinder is a key component in the hydraulic cylinder, and its cleanliness directly affects the normal operation and performance of the hydraulic cylinder. During the production process of the cylinder, dust and other impurities in the processing workshop will more or less adhere to the inner wall of the cylinder. If they are not cleaned in time, the impurities will be blocked in the cylinder. In the subsequent use process, the granular impurities will mix with the hydraulic oil to produce agglomerated foreign matter, which will affect the smooth flow of the oil circuit and scratch the inner wall of the cylinder and the piston, affecting the service life of the parts. Therefore, before installing the cylinder head and guide sleeve at both ends of the cylinder, the inner wall of the cylinder needs to be cleaned.
[0003] The earliest cleaning method was mainly manual cleaning. The operator held a rod-shaped object, and a cleaning block was fixed at the end of the rod-shaped object. A rag was fixed on the cleaning block. During operation, the cylinder was fixed, and then the rod-shaped object was pulled back and forth, and the inner wall of the cylinder was wiped with the rag. This method has been gradually replaced by an automatic cleaning device due to its cumbersome operation and high manpower consumption. The automatic cleaning device is equipped with a driving mechanism for driving the rod-shaped object to move back and forth to replace manual operation, which greatly reduces the labor force. In the actual production process, in order to adapt to the cleaning work of cylinders with different diameters, it is necessary to manually replace cleaning blocks of different outer diameters. At present, the cleaning block and the rod-shaped object are either directly threadedly connected to the rod-shaped object, or the cleaning block is first sleeved on the rod-shaped object and then pressed and locked by a locking nut. Both of the above methods require frequent rotation operations, which is not conducive to the rapid disassembly and assembly of the cleaning block, thereby affecting the replacement efficiency of the cleaning block. In addition, it is difficult to ensure the cleaning effect of the cleaning block on the inner wall of the cylinder with a simple linear reciprocating movement. In summary, the inventors need to improve the cleaning device of the cylinder barrel so as to improve the cleaning effect and facilitate the replacement of the cleaning block. Utility Model Content

DETAILED DESCRIPTION
[0022] Now the utility model is described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the utility model in a schematic manner, so it only shows the components related to the utility model.
[0023] See also Figure 1-Figure 4 The utility model provides a hydraulic cylinder barrel cleaning device for cleaning the inner wall of a cylinder barrel 100. The hydraulic cylinder barrel cleaning device comprises a cleaning platform 10, a slider 20, a fixture 30, a cleaning rod 40, a linear drive mechanism 50, a rotary drive mechanism 60 and a cleaning head 70. The fixture 30 for clamping the cylinder barrel 100 is fixedly installed on the cleaning platform 10. The linear drive mechanism 50 is used to drive the slider 20 to move relative to the cleaning platform 10. The cleaning rod 40 is rotatably arranged on the slider 20 under the action of the rotary drive mechanism 60. The cleaning head 70 is detachably fixed on the end of the cleaning rod 40. When working, the cylinder 100 to be cleaned is fixedly clamped on the fixture 30 to keep the cylinder 100 and the cleaning rod 40 in a coaxial state. Then, under the action of the linear drive mechanism 50, the slider 20 is driven to drive the cleaning rod 40 to move in a straight line, so that the cleaning head 70 extends into the interior of the cylinder 100. At the same time, the rotary drive mechanism 60 drives the cleaning rod 40 to rotate together with the cleaning head 70. Under the movement and rotation of the cleaning head 70, the inner wall of the cylinder 100 can be wiped clean.
[0024] The cleaning head 70 includes a support block 71 and a cleaning cloth 72. The support block 71 is detachably fixedly mounted on one end of the cleaning rod 40. The cleaning cloth 72 is fixedly arranged on the outside of the support block 71. The outer contour of the support block 71 is a circular structure, so that the cleaning cloth 72 is presented in a circular structure. When working, the cleaning cloth 72 is compressed and deformed to fit tightly against the inner wall of the cylinder 100, and cleans the inner wall of the cylinder 100 as the support block 71 moves. During processing, the outer diameter of the support block 71 is slightly smaller than the inner diameter of the cylinder 100, so that the support block 71 can be inserted into the cylinder 100. In specific use, a plurality of support blocks 71 with cleaning cloths 72 and different outer diameters can be prepared, so that the corresponding cleaning head 70 can be selected according to the inner diameter of the cylinder 100 to meet the cleaning needs of different cylinders 100.
[0025] See also Figure 4The two ends of the support block 71 are connected, and the support block 71 is sleeved on the outside of the cleaning rod 40. The support block 71 includes a support body 711 and a step portion 712 protruding from the center of the support body 711. The support body 711 is a circular structure, and the step portion 712 is arranged along the axial direction of the support body 711. The cleaning cloth 72 is fixedly arranged on the outer surface of the support body 711. A limiting edge 41 is arranged on the outer wall of the cleaning rod 40. When the support body 711 is sleeved on the cleaning rod 40 along the length direction of the cleaning rod 40 until the side of the support body 711 away from the step portion 712 abuts against the limiting edge 41, the installation position of the cleaning head 70 along the length direction of the cleaning rod 40 is determined.
[0026] The step portion 712 is slidably provided with a locking pin 73, and the outer wall of the cleaning rod 40 is provided with a locking hole 42. An elastic member 74 is telescopically provided between the locking pin 73 and the step portion 712 along the sliding direction of the locking pin 73, and one end of the locking pin 73 is inserted into the locking hole 42 under the elastic force of the elastic member 74. When the cleaning head 70 is installed, the support block 71 is sleeved on the cleaning rod 40 by the end of the cleaning rod 40. When the support body 711 is in contact with the limiting edge 41, the locking pin 73 is aligned with the locking hole 42, and one end of the locking pin 73 can be inserted into the locking hole 42 under the elastic force of the elastic member 74. At this time, the support block 71 is locked on the cleaning rod 40, and the support block 71 can move and rotate synchronously with the cleaning rod 40.
[0027] In this embodiment, the cross-section of the portion of the cleaning rod 40 for installing the cleaning head 70 is rectangular, and the center of the support block 71 is a rectangular hole. The two cooperate with each other so that after the support block 71 is mounted on the cleaning rod 40, the support block 71 will not rotate relative to the cleaning rod 40. At the same time, it is also convenient for the locking pin 73 to align with the locking hole 42 when the support block 71 is installed in place. In other embodiments not shown, the cleaning rod 40 can also be a cylindrical structure. In this case, the center hole of the support block 71 is also a circular structure. In order to avoid the locking pin 73 and the locking hole 42 from being misaligned when the support body 711 abuts against the limiting edge 41, the contact surfaces of the cleaning rod 40 and the support block 71 can be provided with mutually matching sliding grooves and protrusion structures to achieve directional installation of the support block 71. For example, a protrusion is convexly provided on the wall of the center hole of the support block 71, and a sliding groove is axially provided on the outer wall of the cleaning rod 40. The support block 71 can be mounted on the cleaning rod 40 only after the protrusion is aligned with the sliding groove, thereby ensuring that the locking pin 73 is aligned with the locking hole 42 after the support block 71 is installed in place.
[0028] As a preferred embodiment, a receiving groove 713 is provided on the outer wall of the step portion 712, a through hole 714 penetrating the central hole of the support block 71 is provided on the bottom wall of the receiving groove 713, a plug 715 for sealing the opening of the receiving groove 713 is installed on the step portion 712, the locking pin 73 can slidably pass through the plug 715, and the elastic member 74 is accommodated in the receiving groove 713 and is telescopically arranged between the plug 715 and the bottom wall of the receiving groove 713.
[0029] Furthermore, the locking pin 73 is a cylindrical pin, and a radially protruding abutting edge 731 is provided on the outer wall of the locking pin 73, and one end of the elastic member 74 abuts against the abutting edge 731, and the other end of the elastic member 74 abuts against the plug 715. When the support body 711 is moved into position on the cleaning rod 40, the locking pin 73 is inserted into the locking hole 42 under the elastic force of the elastic member 74; and when the locking pin 73 is pulled outward to overcome the elastic force of the elastic member 74, the locking pin 73 can be disengaged from the locking hole 42, so as to facilitate the removal of the support block 71 from the cleaning rod 40. In addition, the elastic member 74 is a spring, and in other embodiments, the elastic member 74 can also be a rigid and elastic element such as a stainless steel shrapnel or a copper shrapnel.
[0030] As a preferred embodiment, the portion of the outer surface of the step portion 712 where the receiving groove 713 is provided is arranged as a plane, and the plane of the step portion 712 facilitates the arrangement of the receiving groove 713.

For example, a driving gear is provided on the output shaft of the rotary drive motor 61, and a driven gear meshing with the driving gear is provided on the cleaning rod 40. The specific structure of the rotary drive mechanism 60 is not limited.
