Description

Technical Field

[0001] This utility model relates to the field of polishing machine tool technology, and specifically to a polishing pressure regulating device for polishing machine tools. Background Technology

[0002] Polishing machines are mainly assembled from polishing mechanisms and workpiece holders. The polishing mechanism and workpiece holder are used in a one-to-one combination. Moreover, they can be roughly divided into two types according to their usage. One type is where the workpiece holder clamps the workpiece and keeps it stationary, while the polishing mechanism moves back and forth along the workpiece surface to polish it. The other type is where the workpiece holder clamps the workpiece and drives it to rotate, while the polishing mechanism remains relatively fixed in position, and the polishing wheel on the polishing mechanism rotates continuously to polish and grind the workpiece. However, existing polishing machine tools usually require adjustment of the position of the polishing device during use. Although existing adjustment devices can adjust the height of the polishing device during use, they cannot control the pressure of the polishing device during use, thus reducing the practicality of the adjustment device.

[0027] Example 1

[0028] like Figure 1-5As shown, this utility model provides a polishing pressure regulating device for a polishing machine tool, including a lifting unit 1 and a pressure regulating unit 2 disposed on the outer surface of the lifting unit 1 for adjustment. The lifting unit 1 includes a mounting assembly and a lifting component disposed on the outer surface of the mounting assembly. The pressure regulating unit 2 includes a control assembly disposed on the outer surface of the lifting unit 1 and an adjusting component disposed on the outer surface of the control assembly. The mounting assembly includes a mounting base 11, a support frame 12 fixedly connected to the upper surface of the mounting base 11, a limit buckle 13 fixedly connected to the outer surface of the support frame 12, and a positioning block provided on the front side of the support frame 12. The lifting component includes a drive motor 14, the bottom of which is detachably connected to the upper surface of the support frame 12. The drive end of the drive motor 14 is fixedly connected to a lead screw 15 that is rotatably connected to the upper surface of the mounting base 11. The outer surface of the lead screw 15 is threadedly connected to a lifting frame 17. The inner wall of the lifting frame 17 is slidably connected to a limit slide rod 16. The upper and lower ends of the limit slide rod 16 are detachably connected to the outer surfaces of the mounting base 11 and the support frame 12, respectively. When using the polishing pressure adjustment device for the polishing machine tool, first move the limit buckle 13 so that the lifting frame 17 can rise and fall freely. Then start the drive motor 14 to drive the lifting frame 17 to rise and fall in conjunction with the lead screw 15 and the limit slide rod 16. After it rises and falls to a suitable height, the limit buckle 13 is used to assist in limiting the position of the lifting frame 17, thus completing the height adjustment of the pressure adjustment unit 2.

[0029] Example 2

[0030] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the control component includes an oil tank 23, the bottom surface of which is fixedly connected to the upper surface of the support frame 12, the output end of which is detachably connected to a hydraulic pump 24 detachably connected to the top of the support frame 12, the output end of which is detachably connected to an overflow valve 25 detachably connected to the upper surface of the support frame 12, and the adjustment component includes a mounting frame 22, the outer surface of which is fixedly connected to the outer surface of the lifting frame 17, a hydraulic cylinder 21 detachably connected to one side of the mounting frame 22, a movable frame detachably connected to the telescopic end of the hydraulic cylinder 21, a limiting guide rail 27 slidably connected to the outer surface of the movable frame and fixedly connected to the outer surface of the mounting frame 22, and a hydraulic cylinder 26 and a telescopic rod 28 detachably connected to the top of the movable frame, the telescopic ends of which are both... The mounting plate 210 is detachably connected, and a pressure sensor 29 is detachably connected to the outer surface of the moving frame on the upper surface of the mounting plate 210. The connection ends of hydraulic cylinder 26 and hydraulic cylinder 21 are connected to the output end of the relief valve 25. When it is necessary to adjust the pressure of the polishing device, the horizontal position of the polishing device must first be adjusted. During adjustment, the hydraulic pump 24 can be started by starting the PLC controller to work with the oil tank 23 and the relief valve 25 to adjust the change of hydraulic oil inside hydraulic cylinder 21, so that the extension end of hydraulic cylinder 21 drives the moving frame to move. After adjusting to the appropriate position, the change of hydraulic oil inside hydraulic cylinder 26 is controlled by the PLC controller, so that the extension end of hydraulic cylinder 26 drives the mounting plate 210 to rise and fall under the limit of the extension rod 28. During the rising and falling process, the pressure sensor 29 is used to monitor the pressure change, so as to facilitate the adjustment of the pressure.

[0031] The working principle of the polishing pressure regulating device for this polishing machine tool will be explained in detail below.

[0032] like Figure 1-5As shown, this application first uses a PLC as the core control component. When using the polishing pressure regulating device for the polishing machine tool, firstly, the limit buckle 13 is moved so that the lifting frame 17 can rise and fall freely. Then, the drive motor 14 is started, which works with the lead screw 15 and the limit slide bar 16 to drive the lifting frame 17 to rise and fall. After it rises and falls to a suitable height, the limit buckle 13 is used to assist in limiting the position of the lifting frame 17, thus completing the height adjustment of the pressure regulating unit 2. When it is necessary to adjust the pressure of the polishing device, it is necessary to first adjust the position of the polishing device in the horizontal direction. During the adjustment, the PLC controller can be started to control the hydraulic pump 24 to work with the oil tank 23 and the overflow valve 25 to adjust the change of hydraulic oil inside the hydraulic cylinder 21, so that the extension end of the hydraulic cylinder 21 drives the moving frame to move. After adjusting to a suitable position, the PLC controller is used to control the change of hydraulic oil inside the hydraulic cylinder 26, so that the extension end of the hydraulic cylinder 26 drives the mounting plate 210 to rise and fall under the limit of the extension rod 28. During the rising and falling process, the pressure sensor 29 is used to monitor the pressure change, thereby facilitating the adjustment of the pressure.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
