[0024] like Figures 1 to 9 As shown, the present invention is a deburring device for automobile pistons, comprising: a body 1, a piston 3, and a grinding unit 2; the body 1 is also provided with a conveying device for conveying the piston 3 and a controller.

[0025] The grinding unit 2 includes: a coolant tank 21, a liquid return tank 22, a side grinding piece 211 for side grinding the piston 3, and the side grinding piece 211 is slidably installed on the coolant tank 21. The coolant tank 21 is provided with a slide groove for the side grinding piece 211 to slide on the side facing the liquid return tank 22. After the coolant is injected into the coolant tank 21, the side grinding piece 211 is gradually pushed to move as the coolant increases. The specific structure can refer to the syringe injector structure (the difference is that the syringe injector uses a push rod to push the medicine to be discharged, while the present device uses the entry of coolant to drive the side grinding piece 211 to move), and a fixed frame 212 fixedly connected to the liquid storage tank 213.

[0026] The liquid storage box 213 includes: a lifting member 2131, a liquid inlet 2133 fixedly installed on the lifting member 2131, a reset member 2134 fixedly installed in the lifting member 2131, a sliding plate 2135 fixedly installed on the reset member 2134, a connecting rod 2136 fixedly installed on the sliding plate 2135, and an end surface grinding member 2137 fixedly connected to the connecting rod 2136; a liquid outlet connected to the liquid storage box 213 is provided on the surface of the end surface grinding member 2137, and a nozzle can be installed in the liquid outlet to prevent iron filings from entering the liquid storage box 213 during the grinding process and causing pollution. The liquid outlet end of the nozzle shall not be higher than the contact surface between the end surface grinding member 2137 and the piston 3. The nozzle is a controllable nozzle. Through the controller switch, the surface of the connecting rod 2136 is provided with a liquid outlet that is the same as the end surface grinding member 2137, and the nozzle is installed on the liquid outlet; a pressure valve is installed at the liquid inlet 2133.

[0027] The grinding unit 2 also includes: a lifting rod 214, a guide groove 2141 provided on the lifting rod 214, and a fixing piece 2142 fixedly installed on the lifting rod 214; a telescopic cylinder is fixedly connected to the surface of the lifting rod 214; the lifting rod 214 is composed of two parts, one part has a guide groove 2141 on its surface, and the other part is connected to the telescopic cylinder, and the two parts are rotatably connected, that is, when the telescopic cylinder drives the lifting rod 214 to rise and fall, the lifting rod 214 rotates under the action of the guide groove 2141 and the guide block 2232, and no interference occurs; the fixing piece 2142 is an electric telescopic rod, which fixes the piston 3 by abutting against the circular hole of the piston 3; a guide block 2232 is fixedly installed on the recovery box 223.

[0028] When in use, coolant is continuously injected into the coolant tank 21, and the side grinding piece 211 is pushed to move toward the piston 3 and finally contact with the piston 3. At this time, the injection into the coolant tank 21 is stopped and the telescopic cylinder is started. The telescopic cylinder drives the lifting rod 214 to move up and down, and under the action of the guide groove 2141 and the guide block 2232 (the guide block 2232 cooperates with the guide groove 2141, and the guide groove 2141 is spirally opened on the lifting rod 214), the lifting rod 214 performs a rotational motion while performing a linear motion, so that the side grinding piece 211 can fully grind the side surface of the piston 3, and because the coolant drives the side grinding piece 211 to move, during use, the heat generated by the friction between the side grinding piece 211 and the piston 3 will be cooled by the coolant on the other side of the side grinding piece 211 through heat exchange, and because the side grinding piece 211 is supported by the coolant, the support force of the side grinding piece 211 is uniform, and there will be no excessive grinding during grinding, thereby ensuring the grinding effect of the piston 3.

[0029] Here, in order to ensure the cooling effect on the piston 3, the coolant is continuously input into the coolant tank 21 so that the additional coolant is transported to the inside of the fixed frame 212, a spring 2121 is fixedly installed on the fixed frame 212, a sealing plate 2122 is fixedly connected to the spring 2121, a push rod 2123 is fixedly installed on the sealing plate 2122, and a sealing ring groove polishing piece 2124 is fixedly connected to the push rod 2123; the coolant tank 21 is connected to the fixed frame 212, and a pressure valve is provided at the connection point; the liquid storage tank 213 is connected to the fixed frame 212 through a pipeline.

[0030] That is to say, after the coolant enters the fixed frame 212, it will push the sealing plate 2122 to move. When the sealing plate 2122 moves to the other side of the pipeline, the fixed frame 212 is connected to the liquid storage tank 213, and the coolant inside the fixed frame 212 is transported to the liquid storage tank 213 through the pipeline. The coolant inside the liquid storage cavity 221 can be sprayed for cooling by controlling the nozzle switch.

[0031] It should be noted here that when the sealing plate 2122 moves, the sealing ring groove polishing piece 2124 is driven to move through the push rod 2123. When the coolant enters the liquid storage box 213 through the pipeline, the position of the sealing ring groove polishing piece will not interfere with the movement of the piston 3. When the sealing plate 2122 moves, it will drive the spring 2121 to stretch and deform. When the coolant inside the fixed frame 212 is reduced, it can drive the sealing plate 2122 and the sealing ring groove polishing piece 2124 to reset.

[0032] A rotating shaft 2132 is fixedly installed on the lifting member 2131, and one end of the rotating shaft 2132 is fixedly connected to a motor. When it is necessary to grind the end face and the sealing ring groove of the piston 3, the coolant is continuously controlled to enter so that the coolant continues to enter the liquid storage box 213. When the pressure gradually increases, it will enter the lifting member 2131 through the liquid inlet 2133 and push the sliding plate 2135 to move. The sliding plate 2135 drives the end face grinding member 2137 to move downward toward the end face of the piston 3 through the connecting rod 2136. When the end face grinding member 2137 moves to the maximum stroke or contacts the end face of the piston 3 and cannot move, the coolant cannot enter the storage box through the pipeline. Inside the liquid tank 213, the piston 3 plate and the sealing ring groove polishing piece 2124 continue to be pushed toward the piston 3. When the end face polishing piece 2137 and the sealing ring groove polishing piece 2124 are in contact with the piston 3, the input of coolant is stopped. At this time, the motor is started to drive the rotating shaft 2132 to rotate. The rotating shaft 2132 drives the end face polishing piece 2137 and the fixed frame 212 to rotate through the lifting piece 2131, so that the end face polishing piece 2137 and the sealing ring groove polishing piece 2124 work synchronously to polish the end face and the sealing ring groove of the piston 3 respectively. Micro switches are installed on the coolant tank 21 and the fixed frame 212 to detect whether the fixed frame 212 is reset after rotation.

[0033] It should also be added that when the end face polishing piece 2137 and the sealing ring groove polishing piece 2124 move, the spring 2121 and the reset piece 2134 are deformed. When the coolant is reduced, the end face polishing piece 2137 and the sealing ring groove polishing piece 2124 can be driven to reset respectively, which is convenient for the next use.

[0034] It should be noted that when the end face polishing piece 2137 and the sealing ring groove polishing piece 2124 polish the piston 3, since one side of the end face polishing piece 2137 is coolant, the heat generated between the piston 3 and the end face polishing piece 2137 can be directly exchanged during use. When the cooling effect can meet the use requirements, there is no need to spray the coolant, thereby avoiding the cost of recycling the coolant. The sealing ring groove polishing piece 2124 cannot be cooled by heat exchange with the coolant. This is because the sealing ring groove polishing piece 2124 needs to match the size of the sealing ring groove on the piston 3. This results in the sealing ring groove polishing piece 2124 being smaller in size, having a small contact area with the coolant, and having poor heat exchange efficiency. When the above technical solution cannot achieve the ideal cooling effect, the nozzle on the end face polishing piece 2137 and the nozzle on the connecting rod 2136 can spray liquid to cool the piston 3 to ensure the cooling effect.

[0035] That is to say, the present application can store coolant, on the one hand, by using coolant to exchange heat and cool down the polished parts, thereby reducing the loss during use; on the other hand, it can drive the end face polishing part 2137, the sealing ring groove polishing part 2124 and the side polishing part 211 to approach the piston 3, and comprehensively polish the piston 3, which has a good use effect. In addition, when driving the polishing parts to approach the piston 3, the side polishing part 211 moves and separates from the end face polishing part 2137 and the sealing ring groove polishing part 2124. When in use, the side of the piston 3 can be polished first, and then the end face and the sealing ring groove of the piston 3 can be polished after the polishing is completed, so as to avoid simultaneous polishing of the piston 3, which will cause the entire piston 3 to overheat and affect the performance of the piston 3.

[0036] In addition, when installing the piston 3, the piston 3 is sleeved on the outside of the lifting rod 214, and then the piston 3 is pressed down so that the lower end of the piston 3 contacts the positioning plate 1 2224 and the positioning plate 2 22241. At this time, the position of the fixing part 2142 corresponds to the position of the circular hole on the piston 3. The fixing part 2142 can be controlled to extend to complete the fixing of the piston 3.

[0037] Even though the coolant is exchanged with the coolant and the coolant is sprayed out for cooling to ensure that the piston 3 does not have a high temperature that affects its performance during grinding, when the side grinding part 211 is grinding the piston 3, the surface roughness of the grinding part 211 changes after long-term use, which affects the grinding effect of the piston 3. In addition, the temperature of the side grinding part 211 will increase after long-term use, the service life of the grinding part will also be reduced, the daily use loss will increase, and the cost will increase.

[0038] The return liquid tank 22 is fixedly mounted with a capsule 2221, a squeeze block 2222 is mounted on the capsule 2221, a hinge rod 2223 is fixedly mounted on the squeeze block 2222, a positioning plate 2224 is rotatably connected to the hinge rod 2223, and an elastic rod 2225 is fixedly connected to the positioning plate 2224; a liquid storage cavity 221 and a cavity 222 are provided on the return liquid tank 22; the capsule 2221 is mounted on the cavity 222; a sliding movement is performed on the cooling liquid tank 21 It is connected to a second positioning plate 22241, to which an inclined plate 22243 is rotatably connected, and a second capsule 22244 is fixedly installed on the second positioning plate 22241; the second capsule 22244 abuts against the inclined plate 22243; the first capsule 2221 and the second capsule 22244 are connected by a pipeline, and an elastic rod 2225 is fixedly connected to the second positioning plate 22241; both the liquid outlet pipe 2227 and the liquid inlet pipe 2226 are provided with a one-way valve.

[0039] When the piston 3 is side-grinded, the piston 3 moves up and down under the action of the lifting rod 214. When moving downward, the piston 3 squeezes the positioning plate 1 2224 and the positioning plate 2 22241, so that the positioning plate 1 2224 and the positioning plate 2 22241 move downward and squeeze the elastic rod 2225 to contract. At this time, the positioning plate 1 2224 drives the squeezing block 2222 to squeeze the capsule 1 2221 through the hinge rod 2223, so that the coolant in the capsule 1 2221 is discharged through the liquid outlet pipe 2227. Since the water outlet end of the liquid outlet pipe 2227 is fixedly connected with the flow rate detection device, when the capsule 1 2221 pumps the coolant, the flow rate of the water outlet end of the liquid outlet pipe 2227 is detected. The current discharge situation of the coolant can be judged. If the coolant is discharged more, it indicates that the temperature of the piston 3 and the side grinding piece 211 during grinding is high. At this time, the water outlet end of the liquid outlet pipe 2227 is closed, so that the capsule 1 2221 cannot be compressed. When the piston 3 is pressed down, the capsule 2 22244 will be squeezed through the inclined plate 22243 to compress the capsule 2 22244. Since the capsule 1 2221 is connected with the liquid storage chamber 221 through the liquid outlet pipe 2227, when the capsule 1 2221 cannot be compressed, the liquid in the capsule 2 22244 cannot be compressed, so that the piston 3 is guided by the inclined surface to push the side grinding piece 211 away from the piston 3 when moving downward, and the grinding of the piston 3 is stopped.

[0040] It should be noted here that, during the contraction process, the bladder 2221 pumps the used coolant in the recovery tank 223 into the return liquid tank 22. A refrigeration unit for secondary cooling of the coolant is provided inside the return liquid tank 22 to facilitate the recovery and reuse of the used coolant. A side grinding part 211 is fixedly connected to one side of the return liquid tank 22 to ensure the cooling effect during use through heat exchange with the coolant.

[0041] In addition, since the capsule 1 2221 is connected to the recovery box 223 through the liquid inlet pipe 2226, the recovery box 223 is fixedly installed on the elastic rod 2225, and the positioning plate 1 2224 and the positioning plate 2 22241 are in contact with the side grinding piece 211, the iron filings generated when the piston 3 is being ground will fall onto the positioning plate 1 2224 and the positioning plate 2 22241 for collection. When the coolant is sprayed out through the nozzle, the coolant drives the iron filings on the positioning plate 1 2224 and the positioning plate 2 22241 to enter through the through hole 22242. The waste water mixed with iron filings and coolant is initially filtered through the filter plate 2231, and the liquid inlet pipe 2226 extracts the filtered upper coolant, which greatly reduces the possibility of pure iron filings in the coolant and improves the recovery effect of the coolant; the elastic rod 2225 is a telescopic rod of the spring 2121, and the filter plate 2231 can be selected as an activated carbon plate or other filter materials with good filtering effect on the coolant.

[0042] On the one hand, the bladder 2221 can extract the coolant in the recovery box 223 and perform auxiliary treatment on the used coolant. On the other hand, when the bladder 2221 is pumping the coolant, if the amount of coolant pumped at this time is large, the speed at which the bladder 2221 discharges the coolant through the liquid outlet pipe 2227 when it contracts will be fast. In other words, by detecting the flow rate at the water outlet end of the liquid outlet pipe 2227, the current coolant discharge situation can be determined. If the coolant is discharged more, it indicates that the temperature of the piston 3 and the side grinding piece 211 is high during grinding. At this time, the water outlet end of the liquid outlet pipe 2227 is closed. , so that the capsule 1 2221 and the capsule 2 22244 cannot be compressed, and the piston 3 can push the side grinding piece 211 away when moving downward to avoid excessive grinding. Among them, the positioning plate 1 2224 and the positioning plate 2 22241 can, on the one hand, support the piston 3 during installation, and on the other hand, can clean the surface of the side grinding piece 211 during use. Moreover, the up and down movement of the piston 3 can drive the capsule 1 2221 to expand and contract through the positioning plate 1 2224 and the positioning plate 2 22241, so that the capsule 1 2221 can assist in the treatment of the coolant, and the use effect is good.
