Description

Technical Field

[0001] This application relates to the technical field of grinding equipment, and specifically to a fine grinding equipment for processing oil cylinder accessories. Background Technique

[0002] An oil cylinder generally refers to a hydraulic cylinder. A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and makes linear reciprocating motion (or swinging motion). It has a simple structure and reliable operation. When used to achieve reciprocating motion, it can eliminate the deceleration device, and there is no transmission gap, and the motion is stable. Therefore, it is widely used in the hydraulic systems of various machines.

[0003] During the processing of the oil cylinder, the inner surface of the oil cylinder shell needs to be polished to increase the smoothness of the surface sliding and ensure the normal operation of the equipment. The existing grinding equipment mainly grinds the inner surface of the oil cylinder shell by moving the grinding sleeve back and forth. After the grinding sleeve is used for a period of time, some areas of the grinding sleeve are easily worn, resulting in insufficiently fine grinding of the oil cylinder shell by the grinding sleeve, which easily affects the grinding effect of the oil cylinder shell.

[0004] Therefore, there is an urgent need for a fine grinding equipment for processing oil cylinder accessories to solve the problem of insufficiently fine grinding of the grinding equipment. Utility Model Content

[0005] In view of the deficiencies of the prior art, this application provides a fine grinding equipment for processing oil cylinder accessories, which has the advantage of rotating and comprehensively grinding the oil cylinder shell, and solves the problem of insufficiently fine grinding of the grinding equipment.

[0006] To achieve the above object, this application provides the following technical solution: A fine grinding equipment for processing oil cylinder accessories, including a base, a support frame, a fixing plate and a fixing frame. Three groups of the support frames are welded to the top of the base, two groups of the fixing plates are welded to both ends of the top of the base, both ends of the fixing frame are welded to the top of the base, and a grinding mechanism and a clamping mechanism are arranged on the top of the base;

[0007] The grinding mechanism includes a driving motor 1, a connecting rod 1, a connecting sleeve and a grinding sleeve. The driving motor 1 is arranged outside one group of fixing plates. One end of the connecting rod 1 is fixedly connected to the output end of the driving motor 1. The other end of the connecting rod 1 is slidably connected to one end of the connecting sleeve. The grinding sleeve is fixedly connected to the other end of the connecting sleeve by screws. Two groups of electric cylinders are arranged outside one group of fixing plates. The output end of the electric cylinder is fixedly connected to a connecting rod 2. The end of the connecting rod 2 away from the electric cylinder is welded with a connecting piece. The connecting piece is rotatably connected to the outer surface of the connecting sleeve through a bearing.

[0008] The grinding sleeve grinds the oil cylinder fittings by combining movement and rotation, enabling the grinding sleeve to precisely grind the inner surface of the oil cylinder housing comprehensively, so that there are no missed areas during the grinding of the oil cylinder housing, thereby improving the fineness of the grinding of the oil cylinder housing.

[0009] Preferably, a support plate is slidably connected to the outer surface of the first connecting rod, and the support plate is welded to the top of the base.

[0010] Preferably, the clamping mechanism includes a second driving motor, a threaded sleeve, a second threaded rod, clamping pieces and gaskets. Three groups of the second driving motors are arranged on the top of the fixing frame. One end of the threaded sleeve is fixedly connected to the output end of the second driving motor.

[0015] 1. For the precision grinding equipment for processing oil cylinder fittings, by adjusting the elongation length of the connecting sleeve, the connecting sleeve drives the grinding sleeve to insert into the oil cylinder housing to grind the oil cylinder housing. At the same time, when the connecting sleeve drives the grinding sleeve to rotate, it can grind the oil cylinder housing in a rotary manner, enabling the grinding sleeve to precisely grind the inner surface of the oil cylinder housing comprehensively, so that there are no missed areas during the grinding of the oil cylinder housing, thereby improving the fineness of the grinding of the oil cylinder housing.

[0016] 2. For the precision grinding equipment for processing oil cylinder fittings, the oil cylinder housing can be placed inside the support frame. By adjusting the height of the clamping piece, when the clamping piece moves downward, it presses the oil cylinder housing tightly.

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

[0023] Please refer to Figures 1-4 , a fine grinding equipment for processing oil cylinder fittings, including a base 1, a support frame 2, a fixed plate 3 and a fixed frame 4. Three groups of support frames 2 are welded to the top of the base 1. The oil cylinder fittings can be placed on the support frame 2, and the support frame 2 supports the oil cylinder fittings. Two groups of fixed plates 3 are welded to both ends of the top of the base 1, and both ends of the fixed frame 4 are welded to the top of the base 1. A grinding mechanism and a clamping mechanism are arranged on the top of the base 1. The grinding mechanism grinds the oil cylinder fittings through a combination of movement and rotation, making the grinding of the oil cylinder fittings more precise.

[0024] Specifically, the grinding mechanism includes a first driving motor 111, a first connecting rod 112, a connecting sleeve 113 and a grinding sleeve 114. The first driving motor 111 is arranged outside one group of fixed plates 3. One end of the first connecting rod 112 is fixedly connected to the output end of the first driving motor 111. The other end of the first connecting rod 112 is slidably connected to one end of the connecting sleeve 113. The grinding sleeve 114 is fixedly connected to the other end of the connecting sleeve 113 by screws. Two groups of electric cylinders 115 are arranged outside one group of fixed plates 3. The output end of the electric cylinder 115 is fixedly connected to a second connecting rod 116. The end of the second connecting rod 116 away from the electric cylinder 115 is welded with a connecting piece 117. The connecting piece 117 is rotatably connected to the outer surface of the connecting sleeve 113 through a bearing. The outer surface of the first connecting rod 112 is slidably connected to a support plate 118, and the support plate 118 is welded to the top of the base 1.

[0025] Through the above technical solution, when the oil cylinder housing is placed on the top of the support frame 2, the electric cylinder 115 is started. The electric cylinder 115 drives the connecting piece 117 to move through the second connecting rod 116. When the connecting piece 117 moves, it drives the grinding sleeve 114 to insert into the oil cylinder housing through the connecting sleeve 113 to grind the oil cylinder housing. At the same time, the first driving motor 111 is started. The first driving motor 111 drives the first connecting rod 112 to rotate. When the first connecting rod 112 rotates, it drives the grinding sleeve 114 to finely grind the inside of the oil cylinder housing through the connecting sleeve 113. The oil cylinder housing is ground by combining movement and rotation, making the grinding of the oil cylinder housing more delicate; the support plate 118 supports the first connecting rod 112, making the movement of the first connecting rod 112 more stable.

[0026] Specifically, the clamping mechanism includes a second driving motor 311, a threaded sleeve 312, a second threaded rod 313, a clamping piece 314 and a gasket 315. Three groups of second driving motors 311 are arranged on the top of the fixing frame 4. One end of the threaded sleeve 312 is fixedly connected to the output end of the second driving motor 311. The other end of the threaded sleeve 312 is threadedly connected to one end of the second threaded rod 313. The other end of the second threaded rod 313 is welded to the top of the clamping piece 314. Several groups of gaskets 315 are adhesively bonded to the inner side of the clamping piece 314. Guide rods 317 are welded to both sides of the top of the clamping piece 314. The clamping piece 314 is of a semi-circular ring structure. The top of the guide rod 317 is slidably connected to a support sleeve 316. The top of the support sleeve 316 is welded to the bottom of the fixing frame 4.

[0027] Through the above technical solution, when the oil cylinder housing is placed on the top of the support frame 2, the second driving motor 311 is started. The second driving motor 311 drives the threaded sleeve 312 to rotate. When the threaded sleeve 312 rotates, it drives the second threaded rod 313 to move up and down. When the second threaded rod 313 moves, it drives the clamping piece 314 to move up and down. When the clamping piece 314 moves down, it presses the oil cylinder housing tightly. The gasket 315 is located between the oil cylinder housing and the clamping piece 314, increasing the friction between the oil cylinder housing and the clamping piece 314, making the clamping piece 314 clamp the oil cylinder housing more stably and making the grinding of the oil cylinder housing more accurate; when the clamping piece 314 moves, it drives the guide rod 317 to slide up and down inside the support sleeve 316. The guide rod 317 supports the clamping piece 314 to prevent the clamping piece 314 from shaking.

[0028] Specifically, a first threaded rod 211 is threadedly connected inside the other group of fixing plates 3. Both ends of the first threaded rod 211 are fixedly connected to a turntable 212 and a baffle 213 respectively through screws.

[0029] Through the above technical solution, when the oil cylinder housing is placed on the top of the support frame 2, the staff can rotate the turntable 212. The turntable 212 drives the first threaded rod 211 to rotate. When the first threaded rod 211 rotates, it drives the baffle 213 to move, so that the baffle 213 can support oil cylinder housings of different lengths, making the fine grinding equipment more convenient to use.

[0030] During use, the grinding sleeve 114 grinds the oil cylinder fittings by combining movement and rotation, enabling the grinding sleeve 114 to precisely grind the entire inner surface of the oil cylinder housing, preventing areas from being overlooked during the grinding of the oil cylinder housing, thereby improving the fineness of the grinding of the oil cylinder housing.

[0031] Although the embodiments of the present application have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
