Description

Technical Field

[0001] This application relates to the technical field of piston rod grinding, and specifically relates to a supporting device for grinding an oil cylinder piston rod. Background Art

[0002] An oil cylinder is a device that uses liquid to transmit force and power, and is composed of an oil cylinder body and a piston or a plunger. The volume inside the oil cylinder is isolated and expanded by inserting a piston or a plunger. Its general working principle is that the oil liquid pushes each other in the internal cavity of the oil cylinder, thereby transmitting the torque to the moving part of the hydraulic cylinder and driving the movement of the mechanical device. During the processing and manufacturing process of the piston rod of the oil cylinder, a grinding device is required to grind its surface to control its surface roughness. When the piston rod is processed, a supporting device is needed to support it so that the piston rod can be stably ground. A reasonable roughness can reduce the friction and sealing performance during the telescopic process of the piston rod and increase the service life of the piston rod.

[0003] When the existing piston rod supporting device supports the piston rod, the piston rod is prone to move inside the supporting device, resulting in inaccurate grinding of the piston rod. Moreover, the supporting device is inconvenient to adjust the angle of the piston rod, resulting in inconvenient comprehensive grinding of the piston rod, thereby affecting the grinding effect of the piston rod.

[0004] Therefore, there is an urgent need for a supporting device for grinding an oil cylinder piston rod to solve the problem that the supporting device is inconvenient to stably clamp the piston rod. Summary of the Utility Model

[0005] In view of the deficiencies of the prior art, this application provides a supporting device for grinding an oil cylinder piston rod, which has the advantage of stably and comprehensively grinding the piston rod, and solves the problem that the supporting device is inconvenient to stably clamp the piston rod.

[0006] To achieve the above object, this application provides the following technical solution: A supporting device for grinding an oil cylinder piston rod includes a support frame and a connecting plate. Both ends of the connecting plate are welded to the inner sides of two groups of support frames. A clamping mechanism and an adjusting mechanism are arranged on the top of the support frame;

[0007] The clamping mechanism includes an electric cylinder 1, a connecting frame, a clamping block 1 and a clamping block 2. The electric cylinder 1 is arranged at the middle position on the top of the support frame. The rod body at the top of the connecting frame is fixedly connected to the output end of the electric cylinder 1. Both sides of the clamping block 1 are fixedly connected to the outer surface of the connecting frame by screws. Both sides of the clamping block 2 are slidably connected to the outer surface of the connecting frame. Arc-shaped notches are provided on the inner sides of the clamping block 1 and the clamping block 2.

[0008] By adjusting the height of the first clamping block, the first clamping block moves downward to press the piston rod of the oil cylinder against the top of the second clamping block, preventing the piston rod of the oil cylinder from moving. The driving motor drives the pressure plate to rotate through the rod, and when the pressure plate rotates, it drives the piston rod of the oil cylinder to rotate, thereby changing the angle of the piston rod of the oil cylinder, enabling the piston rod of the oil cylinder to be polished comprehensively and stably.

[0009] Preferably, a support column is welded at the middle position of the bottom of the second clamping block, a base is welded at the bottom of the support column, and the bottom of the base is fixedly connected to the top of the support frame by screws.

[0010] Preferably, connecting sleeves are fixedly connected to both sides of the bottom of the second clamping block by screws, and the connecting frame passes through the second clamping block and is slidably connected to the inner side of the connecting sleeve.

[0011] Preferably, the adjusting mechanism includes a support sleeve, a fixing frame, a driving motor and a pressure plate. Two groups of support sleeves are welded to the outside of the support frame, the fixing frame is slidably connected to the outside of the support sleeve, the driving motor is installed on the outside of the fixing frame, and the driving motor is fixedly connected to the pressure plate through a rod body fixedly connected to the output end.

[0012] Preferably, a fixing plate is welded to the outside of the support frame, an electric cylinder two is installed on the outside of the fixing plate, a connecting rod is fixedly connected to the output end of the electric cylinder two, and the end of the connecting rod far from the electric cylinder two is fixedly connected to the inner side of the fixing frame.

[0013] Preferably, the center of the pressure plate is aligned with that of the second clamping block.

[0014] In summary, the present application includes at least one of the following beneficial effects:

[0015] 1. For the support device for polishing the piston rod of the oil cylinder, when the two ends of the piston rod of the oil cylinder are placed inside the two second clamping blocks, by adjusting the height of the first clamping block, the first clamping block moves downward to press the piston rod of the oil cylinder against the top of the second clamping block, preventing the piston rod of the oil cylinder from moving, so that the piston rod of the oil cylinder can be polished stably.

[0016] 2. For the support device for polishing the piston rod of the oil cylinder, when the piston rod of the oil cylinder is placed inside the second clamping block, by adjusting the position of the fixing frame, when the fixing frame drives the pressure plate to move inward, the two pressure plates can press the two ends of the piston rod of the oil cylinder. At the same time, after the driving motor is started, the driving motor drives the pressure plate to rotate through the rod, and when the pressure plate rotates, it drives the piston rod of the oil cylinder to rotate, thereby changing the angle of the piston rod of the oil cylinder, enabling the piston rod of the oil cylinder to be polished comprehensively.

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0023] Please refer to Figures 1-4 , a support device for grinding the piston rod of an oil cylinder, comprising a support frame 1 and a connecting plate 2. Both ends of the connecting plate 2 are welded to the inner sides of two groups of support frames 1. Circular grooves can be inserted with bolts on the front and back sides of the support frame 1 to fix the support frame 1 through the bolts. A clamping mechanism and an adjustment mechanism are arranged on the top of the support frame 1. When grinding the piston rod of the oil cylinder, it can be placed on the clamping mechanism, and the clamping mechanism fixes the piston rod of the oil cylinder.

[0024] Specifically, the clamping mechanism includes a first electric cylinder 111, a connecting frame 112, a first clamping block 113 and a second clamping block 114. The first electric cylinder 111 is arranged at the middle position on the top of the support frame 1. The rod body at the top of the connecting frame 112 is fixedly connected to the output end of the first electric cylinder 111. The two sides of the first clamping block 113 are fixedly connected to the outer surface of the connecting frame 112 through screws. The two sides of the second clamping block 114 are slidably connected to the outer surface of the connecting frame 112. Arc-shaped notches are formed on the inner sides of the first clamping block 113 and the second clamping block 114. A support column 115 is welded at the middle position of the bottom of the second clamping block 114. The bottom of the support column 115 is welded to the base 116. The bottom of the base 116 is fixedly connected to the top of the support frame 1 through screws. Connecting sleeves 117 are fixedly connected to both sides of the bottom of the second clamping block 114 through screws. The connecting frame 112 passes through the second clamping block 114 and is slidably connected to the inner side of the connecting sleeve 117.

[0025] Through the above technical solution, when the two ends of the piston rod of the oil cylinder are placed inside the two groups of clamping blocks II 114, the electric cylinder I 111 is started. The electric cylinder I 111 drives the connecting frame 112 to move up and down. When the connecting frame 112 moves downward, it drives the clamping block I 113 to press the piston rod of the oil cylinder against the top of the clamping block II 114, preventing the piston rod of the oil cylinder from moving. When the connecting frame 112 moves, it slides inside the connecting sleeve 117. The notch opened inside the clamping block II 114 can improve the pressing degree of the clamping block II 114 on the piston rod, making the piston rod more stable; the support column 115 and the base 116 can stably support the clamping block II 114.

[0026] Specifically, the adjusting mechanism includes a support sleeve 211, a fixed frame 212, a driving motor 213 and a pressing disc 214. The two groups of support sleeves 211 are welded to the outside of the support frame 1. The fixed frame 212 is slidably connected to the outside of the support sleeve 211. The driving motor 213 is installed on the outside of the fixed frame 212. The driving motor 213 is fixedly connected to the pressing disc 214 through a rod body fixedly connected to the output end. A fixing plate 215 is welded to the outside of the support frame 1. The pressing disc 214 is aligned with the center of the clamping block II 114. An electric cylinder II 216 is installed on the outside of the fixing plate 215. The output end of the electric cylinder II 216 is fixedly connected to a connecting rod 217. The end of the connecting rod 217 away from the electric cylinder II 216 is fixedly connected to the inside of the fixed frame 212.

[0027] Through the above technical solution, when the piston rod of the oil cylinder inside the clamping block II 114 is polished, the electric cylinder II 216 is started. The electric cylinder II 216 drives the fixed frame 212 to move through the connecting rod 217. The fixed frame 212 slides inside the support sleeve 211. When the fixed frame 212 moves closer to the position of the support frame 1, the fixed frame 212 drives the pressing disc 214 to press against both ends of the piston rod of the oil cylinder through the driving motor 213. At the same time, after the driving motor 213 is started, the driving motor 213 drives the pressing disc 214 to rotate through the rod. When the pressing disc 214 rotates, it drives the piston rod of the oil cylinder to rotate, thereby changing the angle of the piston rod of the oil cylinder, so that the piston rod of the oil cylinder can be polished comprehensively.

[0028] During use, by adjusting the height of the clamping block I 113, the clamping block I 113 moves downward to press the piston rod of the oil cylinder against the top of the clamping block II 114, preventing the piston rod of the oil cylinder from moving. The driving motor 213 drives the pressing disc 214 to rotate through the rod. When the pressing disc 214 rotates, it drives the piston rod of the oil cylinder to rotate, thereby changing the angle of the piston rod of the oil cylinder, so that the piston rod of the oil cylinder can be polished comprehensively and stably.

[0029] Although the embodiments of the present application have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
