Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic cylinder processing, and in particular to a honing mechanism for hydraulic cylinder processing. Background Technology

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. It has a simple structure and reliable operation. When used to achieve reciprocating motion, a speed reduction device can be eliminated, and there is no transmission backlash, resulting in smooth movement.

[0003] Existing hydraulic cylinder honing mechanisms, such as the one disclosed in utility model patent application number 202420327491.X, mainly include a base, with legs below the base, a vertical rod on one side of the upper part of the base, a top plate above the vertical rod, a hydraulic mechanism above the top plate, a hydraulic rod on one side of the lower part of the top plate, and a honing motor on one side of the hydraulic rod. In use, rotating the locking screw moves the second clamping plate to initially clamp and fix the hydraulic cylinder. Then, starting the cylinder drives the telescopic rod to further clamp and fix the hydraulic cylinder from both sides. Starting the hydraulic mechanism drives the hydraulic rod to push the mounting plate downwards. The movement of the mounting plate causes the honing head to move synchronously into the hydraulic cylinder. At this point, since the cover plate is above the honing head, it contacts the upper surface of the base. Starting the honing motor drives the honing head to rotate via the shaft, and in conjunction with the hydraulic rod, the hydraulic cylinder is honed.

[0004] However, most existing honing mechanisms require manual feeding and position adjustment, resulting in low work efficiency and difficulty in large-scale processing. Furthermore, when the honing mechanism is processing continuously, the temperature rises continuously, which can easily affect its service life. Most existing honing mechanisms lack corresponding cooling mechanisms. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a hydraulic cylinder honing mechanism that can not only drive the hydraulic cylinder to load and unload materials, improve positioning accuracy, and save workers the trouble of frequent adjustments, but also cool and lubricate during honing, thus extending the service life of the device.

[0006] This utility model discloses a honing mechanism for hydraulic cylinder processing, comprising a conveying mechanism; it also includes two sets of clamping mechanisms, a driving mechanism, a fixing mechanism, a honing mechanism, and a cooling mechanism. The two sets of clamping mechanisms are mounted on the conveying mechanism and drive the hydraulic cylinder to move. The driving mechanism is mounted on the clamping mechanisms and drives the two sets of clamping mechanisms. The fixing mechanism is mounted on the conveying mechanism and positions the hydraulic cylinder. The honing mechanism is mounted on the conveying mechanism and hones the hydraulic cylinder. The cooling mechanism is mounted on the honing mechanism and cools the honing mechanism. The conveying mechanism drives the hydraulic cylinder to feed material. The two sets of clamping mechanisms cooperate to clamp the hydraulic cylinder. The driving mechanism is activated to drive the two sets of clamping mechanisms to move the hydraulic cylinder directly below the honing mechanism. The fixing mechanism fixes the bottom end of the hydraulic cylinder. The honing mechanism is activated to descend and hones the hydraulic cylinder. Simultaneously, the cooling mechanism sprays coolant into the hydraulic cylinder for lubrication and cooling. The coolant is collected in the fixing mechanism.

[0007] Preferably, the conveying mechanism includes a worktable, a feeding conveyor belt, and a discharging conveyor belt. The bottom end of the worktable is connected to the ground, and a positioning hole is opened on the worktable. The feeding conveyor belt is installed on the worktable, and the discharging conveyor belt is installed on the worktable. The feeding conveyor belt drives the hydraulic cylinder to convey forward. Two sets of clamping mechanisms cooperate to drive the hydraulic cylinder to move to the positioning hole. After honing is completed, the two sets of clamping mechanisms cooperate to drive the hydraulic cylinder to move to the discharging conveyor belt, and the discharging conveyor belt drives the hydraulic cylinder to discharge the material.

The drive mechanism drives the first synchronous pulley to rotate, the first synchronous pulley drives the lead screw to rotate, and the lead screw drives the slider to move between the two sets of baffles. When the hydraulic cylinder moves above the positioning hole, it stops to facilitate the honing mechanism to hone the hydraulic cylinder. After honing is completed, the drive mechanism is restarted to drive the first synchronous pulley to rotate, so that the hydraulic cylinder moves above the unloading conveyor belt. Then, the two sets of first cylinders drive the clamping plate to retract, placing the hydraulic cylinder on the unloading conveyor belt.

[0009] Preferably, the drive mechanism includes a servo motor, a reducer, a transmission shaft, two sets of second synchronous pulleys, and two sets of synchronous belts.

The positioning cylinder is stably raised and lowered by setting two sets of positioning strips. The coolant during honing is transported to the collection box for collection through the drain pipe. When the collection box is full, the handle is used to pull the collection box out for cleaning.
