Description

Technical Field

[0001] The invention relates to a hydraulic oil cylinder outer surface polishing mechanism, in particular to a hydraulic oil cylinder outer surface polishing mechanism, belonging to the technical field of polishing machines. Background Art

[0002] Polishing machines are also called grinders, which are often used for mechanical grinding, polishing and waxing. The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It has a simple structure and reliable operation. When it is used to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth, so it is widely used in the hydraulic systems of various machines. The hydraulic cylinder consists of a cylinder barrel, a cylinder head, a piston and a piston telescopic rod. During the production and installation of the hydraulic cylinder, there may be burrs on the inner surface of the hydraulic cylinder. If it is not cleaned and polished in time, it will cause wear on the piston and the piston telescopic rod, which will cause the hydraulic cylinder to fail to work normally, so the outer surface of the hydraulic cylinder needs to be polished by a polisher.

[0003] When grinding the outer surface of the hydraulic cylinder, tools and materials need to be prepared in the early stage: including sandpaper, grinding wheel, emery cloth, sandpaper tape, lubricating oil, grinder, etc., which can remove defects and oxide layers on the outer surface of the hydraulic cylinder or repair scratches to improve sealing performance and extend service life.

[0004] Grinding wheel is a common mold with large usage and wide application fields. When used, it is controlled by driving equipment to rotate at high speed to grind, groove or cut the workpiece. Common grinding wheels have simple structures and do not have other functions. For example, general grinding wheels are formed by bonding a large number of granular raw materials with rubber solvents. When in use, excessive force may cause the structure of the grinding wheel to be unstable, break, etc., resulting in inability to continue to use. In addition, the grinding wheel will generate a lot of heat due to friction when working. Excessive temperature will affect the stable operation of the grinding wheel and cause the grinding wheel to crack prematurely. Generally, coolant is used for flushing to reduce the temperature, but not all equipment that drives the grinding wheel has matching coolant equipment, which is inconvenient to use. In addition, common equipment only dissipates heat on the surface and not on the inside.

[0005] Therefore, it is urgent to improve the polishing mechanism to solve the above-mentioned problems. Summary of the invention

[0039] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0040] like Figure 1 and Figure 2As shown, a hydraulic cylinder outer surface polishing mechanism provided in this embodiment includes a polishing mechanism body 1, the polishing mechanism body 1 includes a machine base 101, a polishing machine housing 102 and a four-jaw chuck 105 fixedly mounted on the upper surface of the machine base 101, a grinding wheel 103 arranged inside the polishing machine housing 102, and a clamping member slidably arranged on the upper surface of the polishing mechanism body 1 and used in conjunction with the four-jaw chuck 105 to fix the hydraulic cylinder; the clamping member includes a mounting frame 106, a driving motor 108 fixedly mounted on one side of the mounting frame 106, and a chuck 107 fixedly mounted on the output shaft of the driving motor 108 and located on the other side of the mounting frame 106, a transverse electric slide 104 is installed on the lower surface of the mounting frame 106, and a longitudinal electric slider 109 connected to the lower surface of the transverse electric slide 104 is slidably arranged on the machine base 101.

[0041] In order to dissipate heat from the grinding wheel 103 and improve the processing efficiency of the grinding wheel 103, in this embodiment, Figure 2-Figure 9 As shown, a heat dissipation structure 2 for heat dissipation is provided in the grinding wheel 103, and the heat dissipation structure 2 includes a heat-conducting ring 201, a reinforcing ring 202, a heat-conducting rod 203 fixedly connected between the heat-conducting ring 201 and the reinforcing ring 202, and a heat sink 204 fixedly installed on the outside of the heat-conducting rod 203. A vent 205 is provided on the grinding wheel 103 to cooperate with the heat sink 204 for heat dissipation;

[0042] like Figure 4 and Figure 5 As shown, a fan 208 for enhancing the heat dissipation function is arranged in the vent 205, and a fan mounting frame 2081 connected to the inner wall of the vent 205 is installed on the outside of the fan 208. A shielding plate 206 for shielding is slidably arranged on the inner side of the vent 205, and a wind deflector 209 for guiding is detachably installed on the upper surface of the shielding plate 206. The grinding wheel 103 generates heat during processing. At this time, the internal heat-conducting ring 201 has a large contact area with the material of the grinding wheel 103, which absorbs the heat generated by the grinding wheel 103 and transfers it to the heat-conducting rod 203. In this process, the high-speed rotating grinding wheel 103 drives the shielding plate 209 to rotate. The baffle 206 moves, so that the shielding plate 206 moves to contact the vent 205 with the external air, and guides the gas to become an airflow flowing toward the vent 205, so that more gas flows through the vent 205. When the gas passes through the vent 205, it will contact the exposed heat-conducting rod 203 and the heat sink 204 to exchange heat. The gas after complete heat exchange flows out of the vent 205, so that the temperature of the heat-conducting rod 203 in the vent 205 drops. At this time, the heat-conducting rod 203 will transfer the heat from other positions to the vent 205, and then the heat will be taken away by the air, thereby completing the heat dissipation, so that the grinding wheel 103 maintains a suitable working temperature, and the working ability of the grinding wheel 103 is guaranteed.

[0043] The vent 205 is arc-shaped, and a slide groove 2051 is provided inside the vent 205. The shielding plate 206 is slidably installed in the slide groove 2051. A water level observation window 2073 is installed outside the water storage box 2071 for observing the liquid level in the water storage box 2071. A drainage hole is provided inside the grinding wheel 103 for discharging coolant.

[0044] In addition, a mounting hole 2061 is opened inside the baffle plate 206, and a screw 2091 threadedly connected to the mounting hole 2061 is welded on the lower surface of the wind direction plate 209. The wind direction plate 209 is realized and the angle is adjusted by the threaded cooperation between the screw 2091 and the mounting hole 2061, thereby cooperating with the rotation of the grinding wheel 103 to drive the opening and closing of the baffle plate 206.

[0045] It should be noted that there are two vents 205, and the two slide grooves 2051 are connected. A circular guide rod 2052 is fixedly installed inside the two slide grooves 2051. A through hole 2054 is opened inside the baffle plate 206, and the annular guide rod 2052 passes through the inside of the baffle plate 206 through the through hole 2054, ensuring that the baffle plate 206 can move stably.

[0046] In order to make the shielding plate 206 move stably, in this embodiment, as shown in FIG. Figure 7 and Figure 8 As shown, the outer surface of the annular guide rod 2052 is clamped with a clamping ring 2055, and a return spring 2053 is installed around the outer surface of the annular guide rod 2052 on the side opposite to the baffle plate 206 for restoring the baffle plate 206, thereby closing the vent 205 when the grinding wheel 103 stops working.

[0047] At the same time, the return spring 2053 is squeezed by moving the clamping ring 2055 so that it can be fully deformed, thereby ensuring the movement of the shielding plate 206.

[0048] It should be noted that a fixing ring is installed at the center of the grinding wheel 103, and the reinforcing ring 202 is fixedly installed on the outer surface of the fixing ring. When working, the grinding wheel 103 rotates under the drive of the equipment and contacts the workpiece. At this time, the reinforcing ring 202 and the heat-conducting ring 201 are located inside the grinding wheel 103 under the fixation of the central fixing ring and are fixedly connected to the grinding wheel 103. The structural strength is provided by the cooperation of the reinforcing ring 202 and the heat-conducting ring 201.

[0049] like Fig.10As shown, the heat dissipation structure 2 also includes a cooling member 207, which includes a water storage box 2071, a water pipe 2072 fixedly connected to the lower surface of the water storage box 2071, a mounting plate 2074 installed on the outer surface of the heat-conducting ring 201, an abutment plate 2076 arranged above the mounting plate 2074, a connecting pipe 2075 fixedly installed on the inner side of the abutment plate 2076 and connected to the water pipe 2072 and the heat-conducting ring 201 respectively, and an elastic guide component 2077 installed on the upper surface of the mounting plate 2074 and connected to the abutment plate 2076.

[0050] Specifically, the elastic guide assembly 2077 is composed of a telescopic spring 20771 and a guide rod 20772, and the telescopic spring 20771 and the guide rod 20772 are fixedly mounted on the upper surface of the mounting plate 2074, the other end of the telescopic spring 20771 is connected and fixed to the lower surface of the abutment plate 2076, and the guide rod 20772 penetrates the interior of the abutment plate 2076. By moving the abutment plate 2076 downward, the telescopic spring 20771 is deformed, and then the bottom end of the water guide pipe 2072 is connected to the connecting pipe 2075 to achieve the connection between the water storage box 2071 and the heat conduction ring 201, so that the coolant in the water storage box 2071 can be introduced into the heat conduction ring 201, and the heat dissipation of the grinding wheel 103 is further enhanced by cooperating with the heat sink 204, the vent 205 and the fan 208, so that the grinding wheel 103 can achieve multiple heat dissipation methods, so that the heat dissipation work can be performed according to different needs.

[0051] In order to improve the polishing environment of the outer surface of the hydraulic cylinder, in this embodiment, Figure 1 and Figure 2 As shown, a dust suction mechanism 3 is provided on the machine base 101 and the grinding wheel 103 , and the dust suction mechanism 3 includes a dust suction box 301 highly mounted on the upper surface of the machine base 101 , a multi-way pipe 302 fixedly connected to the outside of the dust suction box 301 , and a suction nozzle 304 fixedly connected to the other end of the multi-way pipe 302 .

[0052] Among them, the upper surface of the grinding wheel 103 is installed with a pipe rack 303 by bolts, and the suction nozzle 304 is fixedly installed on the pipe rack 303. Through the coordinated use of the dust box 301, the suction nozzle 304 and the multi-way pipe 302, the waste chips generated by the grinding wheel 103 during grinding can be collected.

[0053] It should be noted that a fan is installed on the side of the dust box 301 away from the multi-channel pipe 302, so that the dust box 301 can form a negative pressure. At the same time, a rotating plate is elastically installed in the dust box 301, and the wind speed is indirectly adjusted by changing the resistance of the dust collection channel. When the power of the fan is greater, the negative pressure in the dust box 301 increases, so that the rotation amplitude of the rotating plate is greater, thereby making the dust collection channel in the dust box 301 larger. At the same time, the power of the fan is smaller, so that the rotation amplitude of the rotating plate is smaller, and then the faster the grinding speed, the faster the negative pressure suction, and the slower the grinding speed, the slower the negative pressure suction.

[0054] like Figure 1-Figure 10 As shown, the principle of the hydraulic cylinder outer surface polishing mechanism provided in this embodiment is as follows:

[0055] When in use, the grinding wheel 103 generates heat. At this time, the internal heat-conducting ring 201 has a large contact area with the material of the grinding wheel 103, and absorbs the heat generated by the grinding wheel 103 and transfers it to the heat-conducting rod 203. In this process, the high-speed rotating grinding wheel 103 will drive the shielding plate 206 to move through the wind direction plate 209, so that the shielding plate 206 moves to contact the vent 205 with the external air, and guide the air to become an airflow flowing to the vent 205, so that more gas flows through the vent 205. When the gas passes through the vent 205, it will contact the exposed heat-conducting rod 203 and the heat sink 204 to exchange heat. The gas after complete heat exchange flows out of the vent 205, so that the temperature of the heat-conducting rod 203 in the vent 205 drops. At this time, the heat-conducting rod 203 will transfer the heat from other positions to the vent 205, and then the heat is taken away by the air, thereby completing the heat dissipation, so that the grinding wheel 103 maintains a suitable working temperature, and the working capacity of the grinding wheel 103 is guaranteed;

[0056] In addition, the bottom end of the water pipe 2072 is connected to the connecting pipe 2075 to realize the connection between the water storage box 2071 and the heat conductive ring 201, so that the coolant in the water storage box 2071 can be introduced into the heat conductive ring 201, and the heat sink 204, the vent 205 and the fan 208 are cooperated to further enhance the heat dissipation of the grinding wheel 103, so that the grinding wheel 103 can achieve a variety of heat dissipation methods, so that heat dissipation can be performed according to different needs.

[0057] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0058] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.
