Description

Technical Field

[0001] This utility model relates to the field of piston rod manufacturing technology, specifically to a polishing device for manufacturing and processing piston rods of rotary locking cylinders. Background Technology

[0002] The piston rod is a component with frequent movement and high technical requirements, commonly used in the motion actuators of hydraulic and pneumatic cylinders. Therefore, the assembly precision requirements for piston rods are extremely stringent. Polishing the piston rod reduces its surface roughness, effectively making the piston rod surface smooth and flat, thus reducing dimensional errors.

[0003] In the prior art, patent document CN217071932U discloses a piston rod polishing device, including a base plate, a sliding frame, and a support frame. The support frame and the sliding frame are respectively disposed on the left and right sides of the upper end of the base plate. A square frame is slidably connected to the middle of the sliding frame, and a slider is slidably connected inside the square frame. A turntable causes multiple gears and multiple polishing rollers to revolve around the main rotating shaft simultaneously. Multiple gears mesh with the inner side of the gear ring for transmission. Multiple polishing rollers can rotate on their own axis as the gears rotate, and simultaneously revolve around the main rotating shaft as the turntable rotates. A round tube can install polishing wax onto the surface of the polishing rollers. The piston rod and polishing wax are fully contacted by the gaps between the multiple polishing rollers, allowing the polishing rollers and polishing wax to polish the surface of the piston rod. This solves the problem that existing polishing devices are not conducive to full contact between the piston rod and polishing rollers during the polishing process, have a large blind zone, and thus do not polish the surface of the piston rod sufficiently.

[0004] To address the issue of existing polishing devices having significant blind spots and difficulty in ensuring sufficient contact between the piston rod and polishing rollers during the polishing process, current technology employs a motor-driven chuck to rotate the piston rod. This relies on the gaps between multiple polishing rollers to ensure full contact between the piston rod and the polishing wax, allowing the polishing rollers to polish the piston rod surface with the wax. However, this method still presents the problem of inconvenience in continuously polishing the piston rod during use, thus reducing the practicality of the polishing device. Utility Model Content

The polishing unit 4 includes a polishing assembly disposed on the outer surface of the processing table 1 and an adjusting assembly disposed on the outer surface of the polishing assembly. The drive assembly includes a mounting frame 31, the outer surface of which is fixedly connected to the outer surface of the processing table 1. A drive motor 35 is detachably connected to the outer surface of the mounting frame 31. A drive rod 36 rotatably connected to the drive end of the drive motor 35 is fixedly connected to the drive end of the drive motor 35. A drive wheel 37 is fixedly connected. The limiting assembly includes a hydraulic cylinder 33. The outer surface of the hydraulic cylinder 33 is detachably connected to the outer surface of the processing table 1.

The upper surface of the placement plate 34 is detachably connected to a feeding wheel 38. When using the piston rod of the rotary locking cylinder to produce a polishing device, the distance between the feeding wheel 38 and the drive wheel 37 is first adjusted according to the size of the piston rod. During adjustment, the PLC controller 2 can be used to control the start of the hydraulic cylinder 33 to drive the placement plate 34 to move under the limit of the limiting slide rod 32, thereby adjusting the distance between the drive wheel 37 and the feeding wheel 38.

Example

[0023] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the polishing assembly includes a support frame 41, the outer surface of the support frame 41 is fixedly connected to the upper surface of the processing table 1, a hydraulic cylinder 42 is detachably connected to the upper surface of the support frame 41, a lifting plate 44 is detachably connected to the telescopic end of the hydraulic cylinder 42, a limiting slide rod 43 is slidably connected to the inner wall of the lifting plate 44 and detachably connected to the outer surface of the support frame 41, a drive motor 45 is detachably connected to the outer surface of the limiting slide rod 43, a polishing wheel 47 is detachably connected to the drive end of the drive motor 45, and the adjustment assembly includes a limiting guide rail 46, the outer surface of the limiting guide rail 46 is connected to the support frame 41.

The inner wall of the limiting block 48 is detachably connected to the fixing bolt 49, which is movably engaged with the outer surface of the limiting guide rail 46. When the outer surface of the piston rod needs to be polished, the position of the limiting block 48 is first adjusted by rotating the fixing bolt 49 in conjunction with the limiting guide rail 46. After the adjustment is completed, the hydraulic cylinder 42 can be started by using the PLC controller 2 to drive the lifting plate 44 to rise and fall under the limit of the limiting slide bar 43, thereby adjusting the height of the polishing wheel 47 so that the polishing wheel 47 fits against the outer surface of the piston rod.

[0024] The working principle of the polishing device used in the production and processing of the piston rod of the rotary locking cylinder will be explained in detail below.

[0025] like Figure 1-5 As shown, when using a polishing device for manufacturing piston rods with a rotary locking cylinder, the distance between the feeding wheel 38 and the drive wheel 37 is first adjusted according to the size of the piston rod. During adjustment, the PLC controller 2 can control the starting hydraulic cylinder 33 to move the placement plate 34 under the limit of the limiting slide bar 32, thereby adjusting the distance between the drive wheel 37 and the feeding wheel 38. After adjustment, the drive motor 35 can be started in conjunction with the drive rod 36 to drive the drive wheel 37 to rotate, which in turn assists the feeding wheel 38 in pushing the piston rod to move horizontally. When polishing the outer surface of the piston rod, the position of the limiting block 48 can be adjusted by rotating the fixing bolt 49 in conjunction with the limiting guide rail 46. After adjustment, the PLC controller 2 can control the starting hydraulic cylinder 42 to move the lifting plate 44 up and down under the limit of the limiting slide bar 43, thereby adjusting the height of the polishing wheel 47 so that the polishing wheel 47 fits against the outer surface of the piston rod. The drive motor 45 is used to drive the polishing wheel 47 to rotate to assist in polishing the outer surface of the piston rod.
