Abstract
Description
Technical Field
[0001] This utility model belongs to the field of hydraulic valve sleeve processing technology, and specifically relates to a polishing device for hydraulic valve sleeve processing. Background Technology
[0002] Hydraulic valve sleeves are one of the key components in hydraulic systems. They are mainly used to guide and position the hydraulic valve core and ensure that the hydraulic oil can flow along the designed path. Therefore, the machining accuracy of hydraulic valve sleeves directly affects the performance and reliability of the entire hydraulic system. Polishing is an important step in the machining process of hydraulic valve sleeves to ensure that their internal surfaces achieve high precision and smoothness.
[0003] Existing polishing equipment for hydraulic valve sleeve processing can achieve very high surface finish and dimensional accuracy by placing the workpiece in a designated position on the hydraulic valve sleeve and then using internal and external cylindrical grinders and surface grinders. However, in actual use, the number of hydraulic valve sleeves processed is usually large, which means that fixing the hydraulic valve sleeve requires a certain amount of time and effort from the processing personnel, thus placing a certain processing burden on them. Utility Model Content
[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a polishing device for processing hydraulic valve sleeves. This device can quickly and stably perform automatic internal support clamping and fixing of the inner wall of the hydraulic valve sleeve when it is being fixed, thereby reducing the processing burden on the operator.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a polishing device for processing hydraulic valve sleeves, including a worktable, a turntable is provided on the upper surface of the worktable, a turntable is rotatably provided on the upper side of the turntable, a plurality of mounting plates are provided on the turntable, and each mounting plate is provided with a clamping column by a driving mechanism, the driving mechanism being used to drive the movement of the clamping column; a second motor is provided in the middle of the bottom of the turntable, and the output shaft of the second motor is fixed to the turntable by a coupling.
[0006] As a further improvement of this utility model, the driving mechanism includes a clamping seat disposed on each mounting plate. The clamping seat is slidably provided with symmetrically distributed sliders, and each slider is provided with a clamping plate. Each clamping plate is detachably mounted with symmetrically distributed clamping posts. The clamping seat is rotatably provided with a bidirectional lead screw, and the sliders are threadedly connected to the bidirectional lead screw. Each clamping seat is provided with a motor, and the output shaft of the motor is fixed to the bidirectional lead screw by a coupling.
[0007] As a further improvement of this utility model, the upper surface of the workbench is provided with symmetrically distributed supports, each support is provided with a linear slide, each linear slide is provided with a polishing box, and each polishing box can be detachably installed with a polishing head.
[0008] As a further improvement of this utility model, symmetrically distributed door panels are rotatably provided on both the left and right sides of the front side of the workbench.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0010] Firstly, the motor drives the bidirectional lead screw connected to it to rotate, causing the clamping plate to move the clamping column in the opposite direction, so that the clamping column is close to the inner wall of the hydraulic valve sleeve and is quickly and stably clamped and fixed.
[0011] Secondly, the threaded relationship between the two-way lead screw and the slider drives the two sliders on the clamping seat to move in opposite directions, which in turn drives the adjacent clamping plate to move in opposite directions, thereby quickly and stably driving the clamping column to move and achieving the internal support and fixation of the hydraulic valve sleeve.
[0012] Third, the linear slide table drives the polishing head on the lower side of the polishing box to move horizontally and vertically. Then, the polishing box drives the polishing head to rotate, causing the rotating polishing head to move horizontally and vertically, thereby polishing the hydraulic valve sleeve.
[0013] Fourth, the output shaft of motor two drives the turntable connected to it to rotate, which in turn causes the turntable to rotate the hydraulic valve sleeve, thereby adjusting the position of the hydraulic valve sleeve to be polished, and thus enabling fast and efficient polishing of the hydraulic valve sleeve.

Detailed Implementation
[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.
[0021] like Figure 1 , 2 As shown, the system includes a worktable 101, a turntable 201 on the upper surface of the worktable 101, a turntable rotatably mounted on the upper side of the turntable 201, a plurality of mounting plates 202 on the turntable, and a clamping column 206 on each mounting plate 202 via a drive mechanism for driving the movement of the clamping column 206; symmetrically distributed supports 104 on the upper surface of the worktable 101, a linear slide 105 on each support 104, a polishing box 106 on each linear slide 105, and a polishing head 107 detachably mounted on each polishing box 106.
[0022] like Figure 2 , 3 As shown, the drive mechanism includes a clamping seat 203 disposed on each mounting plate 202. Symmetrically distributed sliders 204 are slidably disposed inside each clamping seat 203. Each slider 204 is equipped with a clamping plate 205. Symmetrically distributed clamping posts 206 are detachably mounted on each clamping plate 205. A bidirectional lead screw 207 is rotatably disposed inside each clamping seat 203, and the sliders 204 are threadedly connected to the bidirectional lead screw 207. Each clamping seat 203 is equipped with a motor 208, and the output shaft of the motor 208 is fixed to the bidirectional lead screw 207 via a coupling.
[0023] like Figure 2 , 3 As shown, a second motor 209 is installed in the middle of the bottom of the turntable 201. The output shaft of the second motor 209 is fixed to the turntable by a coupling.
[0024] like Figure 1 , 4 As shown, symmetrically distributed door panels 103 are mounted on both the left and right sides of the front side of the workbench 101.
[0025] In use, the hydraulic valve sleeve is placed on the clamping seat 203. Then, the motor 208 drives the bidirectional lead screw 207 connected to it to rotate. The thread relationship between the bidirectional lead screw 207 and the slider 204 causes the two sliders 204 on the clamping seat 203 to move in opposite directions. This causes the adjacent clamping plate 205 to move in opposite directions, which in turn causes the clamping plate 205 to move the clamping column 206 in opposite directions. This allows the clamping column 206 to approach the inner wall of the hydraulic valve sleeve and quickly and stably clamp and fix it.
[0026] Then, the linear slide 105 drives the polishing head 107 on the lower side of the polishing box 106 to move horizontally and vertically. Then, the polishing box 106 drives the polishing head 107 to rotate, so that the rotating polishing head 107 moves horizontally and vertically, thereby polishing the hydraulic valve sleeve.
[0027] Then, the output shaft of motor 209 drives the turntable connected to it to rotate, which in turn causes the hydraulic valve sleeve to rotate, adjusting the position of the hydraulic valve sleeve to be ground, thereby enabling fast and efficient grinding of the hydraulic valve sleeve.
[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
