[0002] In the manufacturing process of hydraulic cylinder parts, the precision grinding process is a key step. Its purpose is to improve the surface quality and dimensional accuracy of the cylinder parts. Traditional precision grinding equipment mainly relies on robotic arms and grinding wheels to grind the cylinder parts. However, this method often has the problems of low efficiency and limited processing accuracy. Especially when dealing with some complex-shaped cylinder parts, traditional processing methods are difficult to meet production needs and may also lead to an increase in processing costs.

[0003] Existing precision grinding devices for hydraulic cylinder parts, especially for piston rods, are prone to localized missed grinding and uneven grinding. Furthermore, during the grinding process, different precision abrasives need to be changed according to the grinding progress, resulting in low grinding efficiency and difficulty in quickly changing the abrasives. Therefore, a precision grinding device for processing hydraulic cylinder parts is proposed. Summary of the Invention

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Example

[0023] Please see Figures 1-4 This utility model provides a technical solution: a precision grinding device for processing hydraulic cylinder parts, which consists of a main body 10 and a shielding mechanism 20.

[0024] In this embodiment, specifically: the main body 10 includes a base 11 and a fixing frame 15. The fixing frame 15 is fixedly connected to the top of the base 11. A rotating sleeve 32 is rotatably installed inside the fixing frame 15. A slot 33 is opened inside the rotating sleeve 32. A locking sleeve 34 is engaged inside the rotating sleeve 32 through the slot 33. An abrasive 35 is fixedly connected inside the locking sleeve 34. A limiting plate 16 is engaged on one side of the rotating sleeve 32. A fixing bolt 31 is threadedly connected to one side of the limiting plate 16 at equal intervals. One end of the fixing bolt 31 is threadedly connected to the rotating sleeve 32. In order to drive the rotating sleeve 32 to rotate, a motor 17 is installed on one side of the base 11. A transmission wheel 18 is installed on the output shaft of the motor 17. A transmission belt 19 is fitted on the outer side of the transmission wheel 18 and the rotating sleeve 32. The transmission wheel 18 is connected to the rotating sleeve 32 through the transmission belt 19.

[0025] In this embodiment, specifically: in order to facilitate clamping and fixing of the accessories, electric guide rails 12 are symmetrically installed on the top of the base 11. A clamping plate 13 is fixedly connected to the movable end of the electric guide rail 12. A limit ring 38 is fixedly connected to the side of the clamping plate 13 near the fixing frame 15. A rubber pad 39 is fixedly connected inside the limit ring 38. A screw 37 is fixedly connected to the side of the clamping plate 13 with the limit ring 38. A threaded sleeve 36 is threadedly connected to the side of the screw 37. An anti-slip sleeve 14 is fixedly connected to the outside of the threaded sleeve 36.

[0026] In this embodiment, specifically: the shielding mechanism 20 includes a shielding cover 21, which is fixedly connected to the top of the base 11. The shielding cover 21 shields the fine grinding area to prevent debris from flying. A cover plate 23 is installed on the top of the shielding cover 21, and a transparent plate 22 is fixedly connected to one side of the shielding cover 21 so that the grinding status can be easily observed through the transparent plate 22.

[0027] Working principle: Select a locking sleeve 34 with an inner diameter corresponding to the size of the accessory, and prepare multiple locking sleeves 34. The abrasive 35 inside each locking sleeve 34 has a different precision. Install the locking sleeve 34 into the rotating sleeve 32, so that the locking sleeve 34 engages with the locking groove 33. Secure the limiting plate 16 to one side of the rotating sleeve 32. Fix the limiting plate 16 and the rotating sleeve 32 with the fixing bolt 31 to complete the installation of the locking sleeve 34 and the abrasive 35. One end of the accessory passes through the locking sleeve 34. Select an anti-slip sleeve 14 that matches the inner diameter of the accessory, and connect the anti-slip sleeve 14 to the threaded sleeve 36. The screw 37 is connected, and the electric guide rail 12 drives the two clamping plates 13 to move towards the accessory, so that the anti-slip sleeve 14 is inserted into the accessory, and one end of the accessory contacts the rubber pad 39. The anti-slip sleeve 14, together with the limiting ring 38, fixes the accessory. The two clamping plates 13 continuously squeeze and clamp the accessory, and drive the accessory to move laterally through the electric guide rail 12. The motor 17 is started to drive the rotating sleeve 32 to rotate, so that the abrasive 35 performs fine grinding on the outside of the accessory. The electric guide rail 12 drives the accessory to move for comprehensive grinding. After completing the grinding of a certain precision, the abrasive 35 of different precision is replaced and the grinding is repeated.
