Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic rod grinding, in particular to a grinding device with a water cooling structure. Background Technique

[0002] The hydraulic rod is also called the piston rod. Generally, a hydraulic rod refers to a mechanical device used to transmit or support force. It uses the principle of liquid pressure transmission to achieve its function. During the production and manufacturing process of the hydraulic rod, in order to improve the smoothness of the shell and the rod of the hydraulic rod, it is necessary to polish and grind the shell and the rod to a certain extent, and a grinding device is required for polishing and grinding.

[0003] Chinese Patent CN217832967U discloses a grinding device for hydraulic rod production, including a grinding drive motor, a grinding disc body connected to the bottom output end of the grinding drive motor, a hydraulic rod main body to be ground and polished directly below the grinding disc body, and a motor support for supporting the grinding drive motor. Clamping mechanisms are arranged on the outer periphery at both ends of the hydraulic rod main body, and a rotation drive mechanism for driving the hydraulic rod main body and the clamping mechanisms to rotate simultaneously is arranged on the side of the clamping mechanisms away from the hydraulic rod main body. Compared with the comparative document, the structure for clamping the hydraulic rod main body in the utility model is designed to be rotatable. The two ends of the hydraulic rod main body are firmly clamped into the center of the supporting inner ring by the annularly distributed locking screws. At the same time, the entire supporting inner ring can rotate under the drive of the servo motor. In this way, during the grinding process, the hydraulic rod main body can rotate according to the grinding requirements.

[0004] In the above patent, during the grinding process of the hydraulic rod, some debris will adhere to the grinding disc body, resulting in low grinding efficiency. At the same time, too high temperature during the grinding process will reduce the service life of the grinding disc body. Content of the Utility Model

A partition plate fixedly connected to the bottom surface of the guide plate is vertically fixedly connected to the center of the bottom plate of the box body. The outer wall of the partition plate is fixedly connected to the inner wall of the box body. An overflow groove is horizontally opened at the upper end of the partition plate.

[0009] Furthermore, a first lead screw is horizontally arranged at the front end inside the box body. The two ends of the first lead screw are respectively rotationally connected to the partition plate and the right plate of the box body. The right end of the first lead screw is fixedly connected to the output end of the second motor. The second motor is fixedly connected to the right wall of the box body. A guide rod parallel to the first lead screw is arranged at the rear end inside the box body. The two ends of the guide rod are respectively fixedly connected to the right wall of the partition plate and the left wall of the box body.

[0010] Furthermore, a connecting rod slidably connected to the guide rod is sleeved on the outer wall of the first lead screw.

[0013] Compared with the prior art, the beneficial effects achieved by the present utility model are:

[0014] 1. In this utility model, the hydraulic rod is placed and installed by opening the movable door, then the movable door is closed. The grinding device is started for grinding, and at the same time, the water pump is started. The water pump extracts liquid through the water suction pipe, enters from the water suction end of the water pump, and is discharged from the water discharge end of the water pump into the drain pipe. The liquid passes through the telescopic hose from the drain pipe into the connecting pipe, and then is sprayed out through the spray head for cleaning. At the same time, the first motor is started, and the output end of the first motor drives the second lead screw to rotate in the box body. The second lead screw makes the driving block reciprocate on the second lead screw. The driving block drives the connecting block to slide in the strip-shaped groove. The connecting block drives the connecting pipe to move through the through groove. The connecting pipe drives one end of the telescopic hose to be pulled, and at the same time, the connecting pipe drives the spray head to move to clean the debris on the grinding disc body. At the same time, the connecting block moves and drives the cross plate through the L-shaped rod, and the motor bracket drives the grinding device and the spray head to reciprocate together. The sprayed liquid falls on the guide plate after passing through the filter plate and slides down from its lower end into the box body, and is located on the left side of the partition plate. After precipitation, the liquid enters the right side of the partition plate through the overflow tank for reuse. By setting the spraying device to clean the debris on the grinding disc body, the attachment of debris on the grinding disc body is reduced, thereby improving the grinding efficiency. At the same time, during the grinding process, the liquid will also cool the grinding position, avoiding the overheating of the grinding disc body and improving the service life of the grinding disc body.

[0015] 2. In this utility model, when the liquid on the right side of the partition plate is less, liquid is added through the liquid adding pipe. At the same time, the second motor is started to make the first lead screw rotate. The first lead screw drives the connecting rod to slide on the guide rod. The connecting rod drives the movable plate to move to the right, so that the liquid accumulates to the right, making the liquid height convenient for the water pump to extract through the water suction pipe. This avoids the problem that the water pump cannot extract enough liquid for a while during the liquid adding process, and also avoids the problems of poor cleaning effect of debris and reduced cooling effect caused by less liquid sprayed by the spray head or inability to spray liquid.
