[0031] The effect achieved by the whole embodiment 1 is that when the device is honing the steering gear of the automobile, the power module 4 of the grinding head is turned on to drive the honing head 201 to start the honing work, at this time the second water pump 234 is also turned on synchronously, the cooling liquid is transmitted to the water spraying head 223 through the water inlet pipe 228 and the stretching water pipe 224, and is sprayed to the inside of the honing steering gear shell by the water spraying head 223. In order to make the cooling liquid uniformly and at high flow rate to cool and clean the key position of the honing head 201 and the steering gear shell, and quickly remove the waste particles generated during processing, the motor ring integrated frame needs to be turned on, the gear 203 drives the gear ring 204 to rotate, the gear ring 204 drives the connecting ring 205 to rotate, and the connecting ring 205 drives the reciprocating threaded sleeve 207; at the same time, the booster ring 210 meshing with the reciprocating threaded sleeve 207 repeatedly moves linearly in the axial direction, and the sliding of the sliding groove 215 and the sliding bar 212 keeps the axial movement period of the threaded sleeve stable. When the booster ring 210 moves upward, the cooling liquid flowing into the sealing cylinder 214 from the liquid inlet hole 206 is pushed upward, and the bottom of the cooling liquid is limited. The water guide hole 221 and the water guide 222 on the inside top of the sealing cylinder 214 flow to the space at the bottom of the sealing cylinder 214. At the initial stage of the upward movement of the sealing cylinder 214, due to the greater weight of the cooling liquid at the top of the liquid inlet hole 206, the cooling liquid is not easily pushed out of the liquid inlet hole 206 by the upwardly moving sealing cylinder 214, but directly flows to the water guide hole 221 at the bottom of the sealing cylinder 214 through the water guide hole 221 and the water guide 222 on the inside top of the sealing cylinder 214. Then flow to the bottom of the sealing cylinder 214, when the cooling liquid at the bottom of the sealing cylinder 214 reaches a certain amount, the water guide hole 221 at the bottom is immersed in the deeper position of the cooling liquid, the gravitational potential energy of the top cooling liquid on the bottom decreases, and the speed of the cooling liquid entering the sealing cylinder 214 slows down. At this time, the sealing ring 208 at the top of the booster ring 210 contacts the bottom of the connecting ring 205, and gradually seals the liquid inlet hole 206 on the connecting ring 205 under the pushing of the booster ring 210 and the pressure spring 209. The cooling liquid cannot enter or exit from the liquid inlet hole 206. The booster ring 210 continues to move upward until the sealing ring 208 retracts into the ring groove 211. During this process, the cooling liquid at the top of the sealing cylinder 214 is squeezed to the bottom by the booster ring 210. The communication groove 213 on the booster ring 210 corresponds to the top water guide hole 221 to avoid blocking the water guide hole 221 and keep it unobstructed. The one-way door 216 inside the water guide hole 221 at the bottom of the sealing cylinder 214 can prevent the cooling liquid from flowing back.
[0032] Embodiment 2, according to Figure 2 Figure 6 As shown, the sliding bar 212 is in sliding connection with the sliding groove 215, the top of the honing head 201 is provided with a rotating groove 217, the bottom of the booster ring 210 is located on the inner side of the rotating groove 217, the top outer side of the booster ring 210 is provided with a communication groove 213, the outer side of the honing head 201 is provided with a communication hole 218, the inner side of the honing head 201 is provided with a pressure distribution bin 220, the inner side of the pressure distribution bin 220 is provided with a liquid injection hole 219, the other end of the liquid injection hole 219 penetrates the honing head 201, the communication hole 218, the pressure distribution bin 220 and the liquid injection hole 219 are all in communication with each other, the liquid injection hole 219 is in position correspondence with the diamond friction sheet on the honing head 201, the bottom of the honing head 201 is provided with a butt joint pipe 231, a plurality of drain holes 232 are provided on the outer side of the butt joint pipe 231, a rubber sleeve 230 is arranged on the outer side of the butt joint pipe 231, the size of the rubber sleeve 230 can be changed according to the size of the honing head 201 used, the diameter of the rubber sleeve 230 is equal to the maximum diameter of the honing head 201, the rubber sleeve 230 is a slope funnel shape with a large top and a small bottom, the bottom inner side of the butt joint pipe 231 is in sliding connection with a drain pipe 233, the other end of the drain pipe 233 is communicated with a second water pump 234, the other end of the second water pump 234 is communicated with a filter box 235, the bottom of the filter box 235 is communicated with a cooling bin 236, the other side of the top of the cooling bin 236 is communicated with a first water pump 229, the output end of the first water pump 229 is communicated with a water inlet pipe 228, the other end of the water inlet pipe 228 is communicated with a stretching water pipe 224, a water spraying head 223 is arranged at the other end of the stretching water pipe 224, the water spraying head 223 is sleeved on the outer side of the honing head 201, the water spraying head 223 is located on the top of the gear ring 204, a moving sleeve frame 225 is arranged on the outer side of the water spraying head 223, a slide rod 226 is in sliding connection with the inner side of the moving sleeve frame 225, a telescopic spring 227 is sleeved on the outer side of the slide rod 226, the telescopic spring 227 is located on the top of the moving sleeve frame 225, and the slide rod 226 is arranged on the inner side of the equipment main machine 1.
[0033] The effect achieved by the whole embodiment 2 is that the coolant in the sealing cylinder 214 is always in communication with the communication hole 218 throughout the process, continuously flowing downward from the spray hole 219, ensuring that the bottom of the diverter is continuously moistened. Based on the reciprocating rod principle, the booster ring 210 rises to the highest point and then descends. Since the spray hole 219 is smaller than the water guide hole 221, most of the remaining coolant in the space of the sealing cylinder 214 at the bottom of the booster ring 210 is quickly pressed out by the descending booster ring 210 through pressure, increasing the flow speed of the coolant and causing the spray hole 219 to form a spray phenomenon. The high-speed sprayed coolant performs close-range spray cleaning on the corresponding honing head 201 area, impacting the waste adhering to the inner surface of the diverter, enhancing the ability to remove residual waste. The coolant with waste flows downward and is limited by the rubber sleeve 230, flowing from the internal funnel-shaped structure to the drain hole 232, entering the drain pipe 233 through the connecting pipe 231, and then being filtered by the filter box 235 and cooled by the cooling box. The coolant is then reused by the first water pump 229. Throughout the process, the moving sleeve 225 on the outside of the water spray head 223 is limited and blocked by the diverter to avoid interfering with the honing work. The moving sleeve 225, the extension spring 227, and the slide rod 226 adapt to the extension state of the honing head 201 to ensure the input angle and amount of coolant.
[0034] Embodiment 3, according to Figure 4 Figure 8 As shown in the figure, the detection mechanism 3 includes a hollow cylinder 301, which is installed inside the equipment host 1. The output end top of the hollow cylinder 301 is provided with a support disc 302. The top of the support disc 302 is provided with a plurality of first air cylinders 303.

[0035] The effect achieved by the whole embodiment 3 is that: because the internal channel of the deflector is longer, the lengthened honing head 201 and the connecting rod clamping it are easy to cause the honing head 201 at the bottom end to deviate from the center when rotating, affecting the honing work. Therefore, the butt joint pipe 231 is arranged at the bottom of the honing head 201, the sliding rod 307 is slidingly installed in the pipe, the pressure sensor 308 is arranged at the bottom of the sliding rod 307, when honing, the hollow air cylinder 301 is opened to drive the supporting disc 302 and the butt joint pipe 231 to move upwards until the top of the butt joint pipe 231 is in contact with the bottom of the honing head 201, at this time, the first air cylinder 303 is opened to drive the lifting disc 304 to move upwards, the lifting disc 304 pushes the sliding rod 307 to slide upwards until the plurality of sliding rods 307 are in close contact with the hole channel arranged at the bottom of the honing head 201 and are limited, at the same time, the pressure sensor 308 at the bottom of the sliding rod 307 is synchronously moved upwards, the top of the pressure sensor 308 contacts the bottom of the sealing sleeve disc and is limited, the values of the five pressure sensors 308 in different directions start to change, whether the honing head 201 is in a horizontal state can be verified through the value changes, then, the butt joint pipe 231 works together with the honing head 201 and always keeps close contact, through detecting the value changes of the five pressure sensors 308 during the rotation of the honing head 201 and the whole honing process, the rotating state of the honing head 201 can be monitored in real time, and the deflector is avoided from being affected by bad processing.
[0036] The working principle of the whole device is: when the device is honing the steering gear of the car, the power module 4 of the grinding head is started to drive the honing head 201 to start honing work, at this time the second water pump 234 is started to transmit the cooling liquid to the water jet head 223 through the water inlet pipe 228 and the stretching water pipe 224, and the cooling liquid is sprayed into the inside of the honing head 201 and the steering gear shell, in order to make the cooling liquid uniform and have high flow rate to cool and clean the key position contacted by the honing head 201 and the steering gear shell, so that the waste particles generated during processing are quickly removed, at this time the motor ring integrated frame is started to drive the gear ring 204 to rotate through the gear 203, the gear ring 204 drives the connecting ring 205 to rotate, the connecting ring 205 drives the reciprocating threaded sleeve 207 at the same time, and the booster ring 210 engaged with the reciprocating threaded sleeve 207 repeatedly moves linearly on the reciprocating threaded sleeve 207, at this time the sliding between the sliding groove 215 and the sliding bar 212 makes the axial movement period of the threaded sleeve stable, when the booster ring 210 moves upward, the cooling liquid flowing into the sealing cylinder 214 from the liquid inlet hole 206 is pushed upward, at this time the bottom of the cooling liquid is limited, so that the cooling liquid flows into the space at the bottom of the sealing cylinder 214 through the water guide hole 221 and the water guide 222 on the inside top of the sealing cylinder 214, at the initial stage of the upward movement of the sealing cylinder 214, because the weight of the cooling liquid at the top of the liquid inlet hole 206 is large, the cooling liquid is not easy to be pushed out of the liquid inlet hole 206 by the sealing cylinder 214 moving upward, but directly flows into the water guide hole 221 at the bottom of the sealing cylinder 214 through the water guide hole 221 and the water guide 222 on the inside top of the sealing cylinder 214, and then flows to the bottom of the sealing cylinder 214, when the cooling liquid at the bottom of the sealing cylinder 214 reaches a certain amount, the water guide hole 221 at the bottom of the sealing cylinder 214 is immersed in a position where the cooling liquid is relatively deep at this time, the gravitational potential energy of the cooling liquid at the top on the bottom is small, the speed of the cooling liquid into the sealing cylinder 214 slows down, and at this time the sealing ring 208 at the top of the booster ring 210 contacts the bottom of the connecting ring 205, and gradually pushes the sealing ring 208 to seal the liquid inlet hole 206 opened on the connecting ring 205 through the booster ring 210 and the pressure spring 209, so that the cooling liquid cannot enter and exit from the liquid inlet hole 206, at this time the booster ring 210 continues to move upward until the sealing ring 208 retracts into the ring groove 211, in this process, the cooling liquid at the top of the sealing cylinder 214 is pressed into the bottom of the sealing cylinder 214 by the booster ring 210 in the form of extrusion, the communication groove 213 opened on the booster ring 210 corresponds to the water guide hole 221 at the top to avoid blocking the water guide hole 221, so as to keep the water guide hole 221 unblocked, and because the one-way door 216 is arranged inside the water guide hole 221 at the bottom of the sealing cylinder 214, the cooling liquid is prevented from flowing back, in the whole process, the cooling liquid in the sealing cylinder 214 is always in communication with the communication hole 218, and the cooling liquid continuously flows downward from the liquid jet hole 219, so as to ensure that the bottom of the steering gear remains wet,When the booster ring 210 rises to the highest point, it will then descend, because the water jet hole 219 of the flow water is smaller than the water guide hole 221, at this time, the cooling liquid in the space of the sealing cylinder 214 at the bottom of the booster ring 210 remains most of the time, the descending booster ring 210 will quickly press the remaining cooling liquid out through pressure, increasing the speed of the cooling liquid flow in the process, so that the water jet hole 219 forms a jet phenomenon, through the high-speed sprayed cooling liquid, the corresponding honing head 201 area is close-range contact type jet cleaning, the waste adhering to the inner surface of the steering vane is impacted, the cleaning ability of the residual waste is improved, at this time, the cooling liquid with waste flows downward through the rubber sleeve 230, flows from the inside of the funnel-shaped rubber sleeve 230 to the drain hole 232, and finally flows to the drain pipe 233 through the interface pipe 231, then is filtered through the filter box 235, cooled by the cooling box, and then is put into circulation again through the first water pump 229 for recycling, in the whole process, the moving sleeve frame 225 outside the water jet head 223 is blocked outside by the steering vane, avoiding interference with the honing work, the moving sleeve frame 225, the telescopic spring 227 and the slide rod 226 adapt to the honing head 201 in the telescopic state, and guarantee the input angle and input amount of the cooling liquid.
[0037] Because the internal channel of the steering vane is long, the lengthened honing head 201 and the connecting rod clamping the honing head 201 are prone to cause the honing head 201 at the bottom end to deviate from the center during rotation, which affects the honing work, therefore, the interface pipe 231 is arranged at the bottom of the honing head 201, the sliding rod 307 slides in the interface pipe 231, the pressure sensor 308 is arranged at the bottom of the sliding rod 307, the hollow air cylinder 301 is opened during honing work, the hollow air cylinder 301 drives the supporting disc 302 and the interface pipe 231 to move upward, until the top of the interface pipe 231 contacts and adheres to the bottom of the honing head 201, at this time, the first air cylinder 303 is opened to drive the lifting disc 304 to move upward, the lifting disc 304 drives the sliding rod 307 to slide upward, until the plurality of sliding rods 307 are tightly combined with and limited by the holes in the bottom of the honing head 201, at the same time, the pressure sensor 308 at the bottom of the sliding rod 307 moves upward synchronously, its top contacts the bottom of the sealing sleeve disc and is limited thereby, the values of the five pressure sensors 308 in different directions begin to change, thereby the change of the values of the five pressure sensors 308 can verify whether the honing head 201 is in a horizontal state, then the interface pipe 231 works with the honing head 201, and always maintains a tightly combined state with the honing head 201, through this way, the change of the values of the five pressure sensors 308 during the rotation and the whole honing work of the honing head 201 is detected randomly, so as to avoid the adverse processing effect on the steering vane.
