Technical Field

[0001] The utility model relates to the technical field of hydraulic oil cylinder polishing, in particular to a hydraulic oil cylinder polishing machine for hydraulic equipment production. Background Art

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy, producing linear reciprocating (or oscillating) motion. It features a simple structure and reliable operation. Reciprocating motion eliminates the need for a reduction gear, eliminates transmission backlash, and provides smooth motion. Therefore, it is widely used in the hydraulic systems of various machines. Hydraulic cylinders consist of a cylinder barrel, cylinder head, piston, and telescopic rod. During the production and installation process, burrs may form on the inner surface of the cylinder. Failure to clean and polish the cylinder promptly can cause wear on the piston and telescopic rod, leading to improper operation of the cylinder.

[0003] The existing hydraulic cylinder polishing machine can only polish the inner surface of a hydraulic cylinder of one size. When polishing the inner surface of a hydraulic cylinder of other sizes, the fixing equipment and polishing head of the hydraulic cylinder need to be replaced. The replacement of the fixing equipment and polishing head is very time-consuming and labor-intensive, which greatly reduces the polishing efficiency of the inner surface of the hydraulic cylinder.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-6 , an embodiment provided by the utility model:

[0024] A hydraulic cylinder polishing machine for hydraulic equipment production: includes a polishing table 1, a guide rail 2 is fixedly connected to the surface of the polishing table 1, a slider 21 is slidably connected to the surface of the guide rail 2, a moving seat 22 is fixedly connected to the surface of the slider 21, a first motor 23 is fixedly connected to the surface of the polishing table 1, a screw rod 24 is fixedly connected to the output shaft of the first motor 23, a square nut 25 is threadedly connected to the surface of the screw rod 24, a second motor 26 is fixedly connected to the surface of the moving seat 22, a rotating rod 27 is fixedly connected to the output shaft of the second motor 26, a chuck 3 is fixedly connected to the surface of the rotating rod 27, a limiting block 31 is fixedly connected to the surface of the chuck 3, a polishing head 32 is snap-connected to the surfaces of the chuck 3 and the limiting block 31, a first limiting bolt 33 is threadedly connected to the surface of the chuck 3, a switching turntable 4 is rotatably connected to the surface of the switching turntable 4, and a switch is opened on the surface of the switching turntable 4. A limiting circular groove 41 is provided, and a support rod 42 is fixedly connected to the surface of the switching turntable 4, and a fixed base 43 is fixedly connected to the surface of the support rod 42. A closed seat 44 is provided on the surface of the fixed base 43, and a fixing nut 45 is fixedly connected to the surface of the polishing table 1. A second limiting bolt 46 is threadedly connected to the surface of the fixing nut 45. The fixed base 43 and the closed seat 44 are fixing devices of the hydraulic cylinder. The polishing machine can quickly replace the fixed base 43, the closed seat 44 and the polishing head 32, which is convenient for polishing hydraulic cylinders of different sizes. By optimizing the method of replacing the fixed base 43, the closed seat 44 and the polishing head 32, the staff saves time and effort in operation, and greatly improves the use efficiency of the polishing machine. At the same time, the replacement of the polishing head 32 is a detachable replacement, which is convenient for maintenance of the polishing head 32 and improves the maintenance efficiency of the polishing head 32.

[0025] Furthermore, the slider 21 slides on the polishing table 1 through the guide rail 2, and the movable seat 22 slides on the surface of the polishing table 1 through the slider 21. During the sliding process, the movable seat 22 will drive the rotating rod 27 and the polishing head 32 to move synchronously through the second motor 26, so that the polishing head 32 continuously performs push-type polishing on the inner surface of the hydraulic cylinder.

[0026] Furthermore, the screw rod 24 rotates on the polishing table 1 through the output shaft of the first motor 23, and the screw rod 24 drives the square nut 25 to slide on the surface of the polishing table 1 through rotation. The square nut 25 drives the moving seat 22 to slide on the polishing table 1, thereby realizing the automatic movement of the moving seat 22. The moving seat 22 can move evenly on the surface of the polishing table 1, thereby ensuring the polishing effect of the polishing head 32 on the inner surface of the hydraulic cylinder.

[0027] Furthermore, the second motor 26 drives the rotating rod 27 to rotate on the surface of the movable seat 22 through the output shaft. The rotating rod 27 drives the chuck 3 and the limit block 31 to rotate synchronously. The chuck 3 and the limit block 31 can drive the polishing head 32 to rotate, thereby performing the polishing task on the inner surface of the hydraulic cylinder.

[0028] Furthermore, multiple groups of limit blocks 31 are provided, and a groove is provided on the surface of the polishing head 32. The groove of the polishing head 32 has the same shape as the chuck 3 and the limit block 31. The limit block 31 drives the polishing head 32 to rotate synchronously through the groove of the polishing head 32. A circular hole is provided on the groove of the polishing head 32, and a threaded groove is provided on the surface of the chuck 3. The first limit bolt 33 passes through the circular hole of the polishing head 32 and is threadedly connected to the threaded groove of the chuck 3. The tightening direction of the first limit bolt 33 on the chuck 3 is the same as the rotation direction of the polishing head 32, which reduces the probability of the first limit bolt 33 loosening on the polishing head 32.

[0029] Furthermore, four groups of support rods 42, fixed bases 43 and closed seats 44 are provided, and the support rods 42, fixed bases 43 and closed seats 44 are rotated on the surface of the polishing table 1 by switching the turntable 4. Four groups of limiting circular grooves 41 are provided, and correspond to each group of support rods 42, fixed bases 43 and closed seats 44 respectively. Different fixed bases 43 and closed seats 44 can fix hydraulic cylinders of different sizes linearly. The fixed bases 43 and closed seats 44 need to be used in conjunction with bolts and nuts. The hydraulic cylinder fixed by the fixed base 43 and closed seat 44 can be polished on its inner surface by the polishing head 32.

[0030] Furthermore, the second limiting bolt 46 is inserted into the limiting circular groove 41 through the fixing nut 45. The second limiting bolt 46 limits the rotation of the switching turntable 4 on the surface of the polishing table 1 through the limiting circular groove 41, thereby limiting the position of the support rod 42, the fixed base 43 and the closing seat 44, and then limiting the position of the hydraulic cylinder, making it convenient to polish the hydraulic cylinder.

[0031] Working principle: Rotate the switching turntable 4 on the surface of the polishing table 1 to change the relative positions of the multiple groups of support rods 42, the fixed base 43 and the closing seat 44. The second limiting bolt 46 is inserted into the limiting circular groove 41 on one side of the switching turntable 4 through the fixing nut 45, thereby limiting the continued rotation of the switching turntable 4, ensuring the position of the fixed base 43 and the closing seat 44 after switching. Rotate the first limiting bolt 33 on the surface of the chuck 3 so that the first limiting bolt 33 falls off the threaded hole of the chuck 3, and then pull the first limiting bolt 33 out of the circular hole of the polishing head 32 At this time, the polishing head 32 can be pulled out from the chuck 3 and the limit block 31. After replacing the polishing head 32 of other specifications on the chuck 3 and the limit block 31, the polishing head 32 is fixed to the chuck 3 and the limit block 31 through the first limit bolt 33. At this time, the replacement of the fixed base 43, the closing seat 44 and the polishing head 32 is completed, which is convenient for polishing the inner surface of the hydraulic cylinder of different specifications. By optimizing the method of replacing the fixed base 43, the closing seat 44 and the polishing head 32, the staff saves time and effort in operation, and greatly improves the efficiency of the polishing machine.

[0032] The polishing head 32 is detachable and replaceable at the end of the rotating rod 27. After the polishing head 32 is damaged, the polishing head 32 can be disassembled for maintenance, which reduces the downtime of the polishing machine, facilitates the maintenance of the polishing head 32, and improves the maintenance efficiency of the polishing head 32.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
