Description

Technical Field

[0001] The invention relates to the technical field of drive shaft processing, and in particular to a drive shaft production and processing device. Background Art

[0002] The drive shaft is a type of working device of the loader. It is a device that can promote the smoothness of the loader so that the drive wheel can rotate at different angular speeds. During the production process, the drive shaft needs to be polished to remove rough particles, scratches, oxide layers and other defects on the surface of the drive shaft to achieve the required surface finish and precision and improve the overall performance of the drive shaft.

[0003] A Chinese patent with application number CN202011002348.6 discloses a drive shaft fixed processing tool for machining mechanical parts, including a base; two clamp structures are installed on the base. Because the rectangular block is welded on the fixed clamp seat; the rectangular groove is opened on the movable clamp seat; the rectangular block and the rectangular groove match, and the rectangular block and the rectangular groove are plugged and connected, and the rectangular block and the rectangular groove together constitute the receiving structure when the drive shaft is placed; it solves the problem that when clamping the drive shaft, the clamping seat must first be adjusted to a diameter larger than the drive shaft; the auxiliary bearing of the drive shaft cannot be achieved, and the drive shaft is easily bumped and worn when the drive shaft is placed; the reciprocating grinding of the coding part of the drive shaft and the automatic feeding of the grinding structure cannot be achieved through structural improvements.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0048] like Figures 1 to 17 As shown, a drive shaft production and processing device of the present invention includes: a machine table 1; a fixing mechanism 2 for fixing the drive shaft; a grinding mechanism 3 for grinding the fixed drive shaft; a pretreatment mechanism 4 for pretreatment of the drive shaft before grinding; and an adjustment mechanism 5 for driving the grinding mechanism 3 and the pretreatment mechanism 4 to adjust their positions.

[0049] The fixing mechanism 2 includes: an end clamping assembly 21, an outer clamping assembly 22, and a rotating assembly 23 for driving the driving shaft to rotate.

[0050] The end clamping assembly 21 includes: an installation box 211; a fixed rod 212 fixedly installed in the installation box 211, and the cross section of the fixed rod 212 is square; a movable tube 213 is sleeved and installed on the fixed rod 212, and a limited opening is provided on the installation box 211, and the movable tube 213 is slidably installed in the inner cavity of the limited opening; a clamping plate 214 fixedly connected to the movable tube 213; a reset spring 215 fixedly installed between the fixed rod 212 and the movable tube 213; a driving unit 216 for driving the clamping plate 214 to move; the driving unit 216 includes: a bidirectional screw 2161 rotatably installed in the machine 1; a bidirectional screw 2161 driving the bidirectional screw A power source 2162 is rotated by 2161, and the power source 2162 is fixedly installed in the machine 1, and the output end of the power source 2162 is connected to the bidirectional screw 2161; the bidirectional screw 2161 is threadedly connected with a movable plate 2163, and a sliding opening is opened on the machine 1, and the movable plate 2163 is slidably connected to the sliding opening; a limit rod 2164 is used to limit the movable plate 2163, and the limit rod 2164 is two and symmetrically arranged. The movable plate 2163 is slidably installed on the limit rod 2164, and both ends of the limit rod 2164 are fixedly installed in the machine 1; the installation box 211 is rotatably installed on the movable plate 2163.

[0051] When the drive shaft needs to be fixed, the drive shaft is placed between the two clamping plates 214. At this time, the power source 2162 is started to drive the bidirectional screw 2161 to rotate, thereby driving the two movable plates 2163 to approach each other. The two movable plates 2163 drive the adjacent installation boxes 211 to approach each other, and then drive the two clamping plates 214 to approach each other and abut against the two ends of the drive shaft.

[0052] When the two clamping plates 214 are respectively in contact with the ends of the driving shaft, the clamping plates 214 no longer move, and thus the movable tube 213 no longer moves. At this time, the mounting boxes 211 continue to approach each other and drive the fixing rod 212 to move, thereby compressing the return spring 215. At this time, the elastic force of the return spring 215 can generate a thrust on the movable tube 213 and drive the clamping plates 214 to clamp and fix the driving shaft, thereby clamping and fixing the end of the driving shaft.

[0053] It should be added here that the power source 2162 is preferably: a motor.

[0054] The outer clamping assembly 22 includes: a fixed cylinder 221 fixedly installed in the installation box 211; a rotating plate 222 rotatably installed on the fixed cylinder 221; a circular opening provided on the rotating plate 222, and the movable tube 213 passes through the inner cavity of the circular opening; a rolling member 228 rotatably installed in the circular opening; a guide groove 223 provided on the movable tube 213, and the guide groove 223 is spirally arranged; a guide groove 224 provided on the rotating plate 222; a limiting groove 227 provided on the installation box 211; a guide rod 225 passing through and installed in the guide groove 224 and the limiting groove 227; a clamping plate 226 fixedly connected to the guide rod 225, and the clamping plate 226 is V-shaped; a sliding rod fixedly installed in the limiting groove 227, and the guide rod 225 is slidably installed on the sliding rod. Through the setting of the sliding rod, on the one hand, the guide rod 225 can be limited, and on the other hand, the guide rod 225 can be prevented from escaping from the limiting groove 227.

[0055] When the clamping plate 214 no longer moves, and thus the movable tube 213 no longer moves, the installation boxes 211 continue to approach each other and drive the fixed cylinder 221 to move, the fixed cylinder 221 drives the rotating plate 222 to move, and the rotating plate 222 drives the rolling element 228 to roll in the inner cavity of the guide groove 223. Since the guide groove 223 is spiral, when the rolling element 228 moves along the path of the guide groove 223, it can drive the rotating plate 222 to rotate. Under the guidance of the guide groove 224, the rotating plate 222 drives the guide rod 225 to move along the path of the limiting groove 227, thereby driving the adjacent clamping plates 226 to approach each other, thereby clamping and fixing the outer side of the drive shaft.

[0056] By setting the end clamping assembly 21 and the outer clamping assembly 22, the end and the outer side of the drive shaft can be automatically fixed synchronously, thereby realizing multi-directional fixation of the drive shaft, improving the stability of the fixation, and avoiding displacement of the drive shaft during grinding, which affects the grinding quality.

[0057] When the grinding is completed, the power source 1 2162 is started to rotate in the reverse direction, thereby driving the clamping plate 1 214 and the clamping plate 2 226 to release the fixed state of the drive shaft, so that the drive shaft can be taken out and replaced with the drive shaft to be ground.

[0058] The rotating assembly 23 includes: a rotating rod 232 rotatably mounted on the movable plate 2163; a power source 236 for driving the rotating rod 232 to rotate, and the power source 236 is fixedly mounted on the movable plate 2163; a sleeve 231 mounted on the outer edge of the rotating rod 232; a linkage gear 234 respectively fixedly mounted on the rotating rod 232 and the sleeve 231; a linkage gear ring 235 fixedly mounted on the installation box 211, and the linkage gear 234 and the linkage gear ring 235 are arranged to mesh with each other; a slide groove opened in the sleeve 231; a limit bar 233 fixedly mounted on the rotating rod 232; and the limit bar 233 is slidably mounted in the slide groove.

[0059] When the drive shaft is fixed, start the power source 236 to drive the rotating rod 232 to rotate, the rotating rod 232 drives the limit bar 233 to rotate, the limit bar 233 drives the sleeve 231 to rotate, so that the two interlocking gears 234 can be driven to rotate synchronously, the interlocking gear 234 drives the interlocking gear ring 235 to rotate, so that the installation box 211 can be driven to rotate, and then the drive shaft can be driven to rotate, so that after the grinding of one side of the drive shaft is completed, there is no need to re-fix the drive shaft, and the grinding side of the drive shaft can be adjusted, so that the circumferential comprehensive grinding of the drive shaft can be achieved, thereby improving the grinding efficiency.

[0060] It is to be added here that the power source 236 is preferably: a motor; the rolling element 228 is preferably: a bull's eye ball.

[0061] In the present invention, through the setting of the fixing mechanism 2, on the one hand, the end and the outer side of the driving shaft are automatically fixed synchronously, thereby realizing multi-directional fixation of the driving shaft, improving the stability of the fixation, and avoiding displacement of the driving shaft during grinding, which affects the grinding quality; on the other hand, it can drive the fixed driving shaft to rotate, realizing comprehensive circumferential grinding of the driving shaft, and improving the grinding efficiency.

[0062] The adjustment mechanism 5 includes: a fixed box 51; a support column 55 rotatably mounted on the fixed box 51; a mounting plate 56 fixedly mounted on the end of the support column 55; a driven gear 54 fixedly sleeved on the support column 55; a driving gear 53 meshingly connected to the driven gear 54; and a power source 52 that drives the driving gear 53 to rotate, and the power source 52 is fixedly mounted in the fixed box 51.

[0063] In the present invention, two groups of fixing mechanisms 2 are provided, which are symmetrically arranged on both sides of the fixing box 51. Since the grinding mechanism 3 and the pretreatment mechanism 4 are both installed on the adjustment mechanism 5, when the two groups of fixing mechanisms 2 fix the driving shafts, the pretreatment mechanism 4 is started to pretreatment the adjacent driving shafts. After the pretreatment is completed, the adjustment mechanism 5 is started to exchange the position of the pretreatment mechanism 4 and the grinding mechanism 3, so that the grinding mechanism 3 is moved to the top of the pretreated driving shaft. At this time, the grinding mechanism 3 can be started to grind the pretreated driving shaft, and the pretreatment mechanism 4 can pretreatment the other driving shaft.

[0064] After the grinding mechanism 3 finishes grinding the driving shaft, the driving shaft is replaced, and the adjustment mechanism 5 is started to exchange the positions of the grinding mechanism 3 and the pretreatment mechanism 4, so as to proceed to the next step of processing.

[0065] Specifically, starting power source three 52 drives driving gear 53 to rotate, driving gear 53 drives driven gear 54 to rotate, driven gear 54 drives support column 55 to rotate, thereby driving mounting plate 56 to rotate, and further driving pretreatment mechanism 4 and polishing mechanism 3 to exchange positions.

[0066] By alternately exchanging the pretreatment mechanism 4 and the grinding mechanism 3, the drive shaft can be pretreated and ground continuously, thereby improving the work efficiency.

[0067] It is to be added here that the power source three 52 is preferably: a motor.

[0068] The grinding mechanism 3 includes: a grinder 32, which is composed of a motor and a grinding disc, and the grinding disc and the motor are detachably connected; a moving component 31 that drives the grinder 32 to move, and the moving component 31 is fixedly installed on the mounting plate 56; and a cooling component 33 that cools the drive shaft during grinding.

[0069] The moving assembly 1 31 is composed of a cylinder that drives the grinder 32 to move vertically and a linear moving module that drives the cylinder to move horizontally.

[0070] When grinding the drive shaft, first start the linear motion module to move the grinder 32 to one end of the drive shaft, and start the cylinder to drive the grinder 32 to move downward so that the grinding disc of the grinder 32 contacts the surface of the drive shaft. At this time, start the grinder 32 for grinding.

[0071] When the grinder 32 is started, the linear moving module is started to drive the grinder 32 to move back and forth. At the same time, the rotating component 23 is started to drive the driving shaft to rotate, thereby achieving comprehensive grinding of the driving shaft.

[0072] When grinding, first use a coarse grinding disc to perform coarse grinding on the drive shaft; then replace the fine grinding disc to perform fine grinding on the drive shaft.

[0073] While grinding, the cooling assembly 33 is started to cool the drive shaft and the grinding disc; the cooling assembly 33 includes: a cooling box 331 fixedly mounted on the moving assembly 31, and the grinder 32 is mounted on the cooling box 331 through a fixing frame; a fixing plate 332 fixedly mounted on the cooling box 331; a limiting frame 333 fixedly mounted on the fixing plate 332; a capsule 334 fixedly mounted in the limiting frame 333, and the capsule 334 is connected to the cooling box 331. The liquid spray head 335 is connected to the capsule 334 through a liquid inlet pipe, and a first one-way valve is installed on the liquid inlet pipe; the liquid spray head 335 is connected to the capsule 334, and the liquid spray head 335 and the capsule 334 are connected through a liquid outlet pipe, and a second one-way valve is installed on the liquid outlet pipe; a linkage unit 336 that drives the capsule 334 to compress and recover; an adjustment unit 337 that adjusts the spraying range of the liquid spray head 335; the linkage unit 336 includes: a cylinder 3361 rotatably installed in the limit frame 333; a cylinder 3361 slidably installed on the cylinder The ring 3362 on the cylinder 3361 has a slider fixedly mounted on the ring 3362. A movable groove is provided in the limit frame 333. The slider is slidably mounted in the movable groove. The ring 3362 can be limited by the cooperation between the slider and the movable groove so that the ring 3362 can keep moving in a straight line. The guide groove 2 3363 is provided on the cylinder 3361. The guide groove 2 3363 has two U-shaped grooves in opposite directions and connected to each other. The guide groove 2 3363 is rotatably mounted on the ring 33 The second rolling member 3364 in 62 is rollingly installed in the second guide groove 3363; the slide plate 3366 fixedly connected to the capsule 334 is slidably installed in the limit frame 333; the connecting rod 3365 is fixedly installed between the slide plate 3366 and the ring 3362, and the two ends of the connecting rod 3365 are respectively connected to the slide plate 3366 and the ring 3362; the cylinder 3361 and the grinder 32 are connected by a belt drive.

[0074] Specifically, when the grinder 32 is started, the cylinder 3361 is driven to rotate by the belt, so that the rolling element rolls along the path of the guide groove 3363, thereby driving the ring 3362 to move. Under the limiting action of the movable groove and the slider, the ring 3362 makes a linear reciprocating movement along the axial direction of the cylinder 3361, thereby driving the connecting rod 3365 to make a linear reciprocating movement. The connecting rod 3365 drives the slide plate 3366 to make a linear reciprocating movement, thereby driving the capsule 334 to compress and recover.

[0075] When the capsule 334 is compressed, the first one-way valve is closed and the second one-way valve is opened. At this time, the coolant in the capsule 334 is transported to the spray head 335 through the liquid outlet pipe, and is sprayed on the surface of the drive shaft and the grinding disc through the spray head 335, so that the drive shaft can be cooled during grinding, thereby quickly reducing the heat generated during the grinding process, preventing the grinding disc and the drive shaft from being deformed or damaged due to high temperature, thereby ensuring the grinding accuracy and the quality of the drive shaft; and the coolant can wash away the grinding chips and dust generated during the grinding process, keep the grinding disc clean and the surface of the drive shaft tidy, thereby reducing scratches and unevenness caused by the accumulation of grinding chips.

[0076] When the bladder 334 is restored, the first one-way valve is opened and the second one-way valve is closed. At this time, the coolant in the cooling box 331 is sucked into the bladder 334 through the liquid inlet pipe, ready for subsequent use.

[0077] During the grinding process, the capsule 334 is compressed and restored back and forth, thereby continuously spraying the coolant on the surface of the drive shaft and the grinding disc, thereby achieving continuous cooling of the drive shaft and the grinding disc.

[0078] When grinding the drive shaft, it is necessary to perform rough grinding first and then fine grinding. The goal of the rough grinding stage is to quickly remove larger unevenness on the drive shaft surface and contaminants attached to the drive shaft surface. Therefore, a higher grinding speed is usually selected for rough grinding to speed up the process and improve efficiency; a higher grinding speed helps to cover a larger grinding area in a short time, thereby shortening the overall grinding time; however, in the fine grinding stage, the goal is to further improve the smoothness and accuracy of the drive shaft surface and remove minor defects left in the rough grinding stage; in order to achieve a finer surface treatment, the grinding speed is usually reduced during fine grinding; a slower grinding speed helps to better control the grinding depth and uniformity to ensure that the desired surface quality is achieved.

[0079] It can be seen from the above that when fine grinding and rough grinding are performed on the drive shaft, the rotation speed requirements of the grinder 32 are different.

[0080] Since rough grinding requires a higher rotation speed and greater grinding force, relatively more heat is generated during the grinding process, so a relatively large amount of spray liquid is required; the rotation speed and grinding force of fine grinding will be reduced, and the friction heat generated is relatively small, so a relatively small amount of spray liquid is required.

[0081] When the drive shaft is roughly ground, the grinder 32 drives the rough grinding disc to rotate at a relatively fast speed, thereby driving the rotation speed of the cylinder 3361 to be fast, so that the frequency of compression and recovery of the capsule 334 is fast, thereby making the spraying amount of the coolant large.

[0082] When fine grinding the drive shaft, the grinder 32 drives the fine grinding disc to rotate at a relatively slow speed, thereby driving the rotation speed of the cylinder 3361 to be slow, making the compression and recovery frequency of the capsule 334 slow, thereby making the spraying amount of the coolant small.

[0083] It should be added here that fine grinding does not require as much coolant spraying as rough grinding, because excessive coolant spraying may affect the friction of the fine grinding disc, reduce the grinding efficiency, and may even leave water marks on the material surface or cause other adverse effects.

[0084] In the present invention, by setting the cooling component 33, the rotation speed of the grinder 32 can be adjusted according to the rough grinding section and the fine grinding section, thereby adjusting the spraying amount of the coolant, thereby realizing automatic adjustment of the coolant flow rate in different grinding stages to meet the requirements of the coolant flow rate in different grinding stages.

[0085] The adjustment unit 337 includes: a transmission gear 3371 rotatably mounted on the fixed plate 332; a transmission rack 3372 meshingly connected to the transmission gear 3371; a mounting frame 3373 coaxially connected to the transmission gear 3371; an arc plate 3474 fixedly mounted on the mounting plate 56; a guide groove three 3475 provided on the arc plate 3474, the guide groove three 3475 being S-shaped; the transmission rack 3372 is fixedly connected to the slide plate 3366; the liquid spray head 335 is hingedly mounted on the mounting frame 3373, and the liquid spray head 335 is slidably mounted in the guide groove three 3475.

[0086] When the slide plate 3366 makes a linear reciprocating movement, it can drive the transmission rack 3372 to make a linear reciprocating movement, thereby driving the transmission gear 3371 to rotate forward and reverse, thereby driving the mounting frame 3373 to swing along the circumference of the transmission gear 3371, and the mounting frame 3373 drives the spray head 335 to swing along the circumference of the transmission gear 3371, thereby expanding the spraying range of the spray head 335, so that the spray head 335 can spray the coolant on the drive shaft and the grinding disc to cool the drive shaft and the grinding disc.

[0087] Since the spray head 335 is slidably installed in the guide groove three 3475, the guide groove three 3475 is S-shaped. When the spray head 335 moves along the path of the guide groove three 3475, the spray head 335 swings at the hinge with the mounting frame 3373, which further expands the spraying range of the spray head 335 and improves the cooling effect.

[0088] In the present invention, through the setting of the grinding mechanism 3, on the one hand, the coolant can be transported while grinding; on the other hand, the rotation speed of the grinder 32 can be adjusted according to the rough grinding section and the fine grinding section, thereby adjusting the spraying amount of the coolant, thereby realizing automatic adjustment of the coolant flow rate in different grinding stages to meet the demand for coolant flow rate in different grinding stages; and the spraying range of the spray head 335 can be adjusted to improve the cooling effect.

[0089] It should be added here that the cooling box 331 is also provided with a stirring plate (not shown) coaxially connected to the cylinder 3361, and a semiconductor refrigeration plate (not shown) for cooling the coolant in the cooling box 331. The coolant can be cooled by the semiconductor refrigeration plate, and the stirring plate can be driven to rotate by the cylinder 3361 to stir the coolant, so that the coolant in the cooling box 331 is cooled evenly, thereby ensuring the cooling effect when grinding the drive shaft.

[0090] Since dust and oil stains are easily attached to the surface of the drive shaft during the production process, the pretreatment mechanism 4 can remove the oil stains and dust, which is convenient for subsequent comprehensive polishing of the drive shaft surface and improves the polishing effect.

[0091] The pretreatment mechanism 4 includes: an adsorption smear body 43, the adsorption smear body 43 includes: a roller, a sponge layer fixedly mounted on the outside of the roller; a moving component 41 that drives the adsorption smear body 43 to move, and the moving component 41 is fixedly installed on the mounting plate 56; a liquid storage tank 42 fixedly installed on the moving component 41; a conveying component 44 that conveys the liquid in the liquid storage tank 42 to the adsorption smear body 43; and a cleaning component 45 that assists in cleaning the drive shaft.

[0092] The second moving assembly 41 is composed of a cylinder that drives the liquid storage tank 42 to move vertically and a linear moving module that drives the cylinder to move horizontally.

[0093] A partition is fixedly installed on the inner wall of the liquid storage tank 42, thereby dividing the liquid storage tank 42 into two independent storage spaces, one storage space for storing detergent, and the other storage space for storing clean water. By independently storing the detergent and the clean water, the storage time can be increased. Compared with storing the detergent and the clean water after mixing, the problem of reduced decontamination ability due to long-term storage of the mixed liquid is avoided. At the same time, when using, a certain amount of detergent and clean water are respectively absorbed and mixed, which avoids the problem of excessive mixed liquid and waste.

[0094] When pre-treating the drive shaft, first start the linear motion module to move the adsorption smear body 43 to one end of the drive shaft, and start the cylinder to drive the adsorption smear body 43 to move downward, so that the adsorption smear body 43 abuts against the surface of the drive shaft.

[0095] The conveying assembly 44 includes: a fixed tube 441 fixedly mounted on the liquid storage tank 42; a mobile tube 442 slidably mounted in the fixed tube 441, the adsorption smearing body 43 is rotatably mounted in the mobile tube 442, and a fourth one-way valve is installed on the mobile tube 442; a linkage spring 445 that drives the mobile tube 442 to reset, one end of the linkage spring 445 is fixedly connected to the mobile tube 442, and the other end of the linkage spring 445 is fixedly connected to the liquid storage tank 42; a piston 444 slidably mounted in the mobile tube 442; a connecting rod 443 fixedly mounted between the piston 444 and the liquid storage tank 42; a liquid guide tube 446 connecting the mobile tube 442 and the liquid storage tank 42, two liquid guide tubes 446 are provided, which absorb detergent and clean water respectively, and a third one-way valve is installed on both liquid guide tubes 446; a mixing unit 447 for mixing and stirring the detergent and clean water during the liquid inlet and outlet process.

[0096] When the adsorption smear body 43 abuts against the surface of the driving shaft, the adsorption smear body 43 no longer moves, and the moving tube 442 no longer moves. When the cylinder continues to drive the liquid storage tank 42 to move downward, the liquid storage tank 42 drives the fixed tube 441, the connecting rod 443, and the piston 444 to move downward. The mixed liquid in the inner cavity of the moving tube 442 can be squeezed by the piston 444. At this time, the third one-way valve is closed and the fourth one-way valve is opened, so that the mixed liquid flows into the adsorption smear body 43 through the moving tube 442. At this time, the linear moving module is started to drive the adsorption smear body 43 to move back and forth, so that the mixed liquid can be smeared on the surface of the driving shaft to remove oil and dust. At the same time, the driving shaft can be driven to rotate by starting the rotating component 23, so that the mixed liquid is fully smeared on the surface of the driving shaft, thereby improving the efficiency of pretreatment.

[0097] As the liquid storage tank 42 moves downward, the linkage spring 445 can be compressed. When the coating is completed, the adsorption coating body 43 is separated from the surface of the drive shaft. The elastic force of the linkage spring 445 can drive the movable tube 442 to reset. As the movable tube 442 is displaced relative to the piston 444, a negative pressure is formed in the inner cavity of the movable tube 442. At this time, the third one-way valve is opened and the fourth one-way valve is closed. At this time, clean water and cleaning agent enter the inner cavity of the movable tube 442 through the liquid guide tube 446 respectively to form a mixed liquid, which is ready for subsequent use.

[0098] By setting the conveying component 44, the automatic liquid discharge can be realized during the process of applying the mixed liquid to the driving shaft, and the automatic liquid intake can be realized after the application is completed, without manual intervention, thereby improving the automation performance of the device.

[0099] The mixing unit 447 includes: a connecting rack 4471 fixedly mounted on the fixed tube 441; a connecting gear 4472 meshingly connected to the connecting rack 4471, and the connecting gear 4472 is rotatably mounted on the mobile tube 442; an active bevel gear 4473 coaxially connected to the connecting gear 4472, and a driven bevel gear 4474 meshingly connected to the active bevel gear 4473, a mounting bar is fixedly mounted in the mobile tube 442, and the driven bevel gear 4474 is rotatably mounted on the mounting bar; a stirring blade 4475 coaxially connected to the driven bevel gear 4474; an inner cylinder 4476 and a dispersion plate 4477 fixedly mounted in the mobile tube 442, a fourth one-way valve is mounted between the inner cylinder 4476 and the dispersion plate 4477, and a plurality of through holes are provided on the dispersion plate 4477; and a guide groove is provided in the inner cylinder 4476.

[0100] When the cleaning agent and clean water are absorbed, the movable tube 442 moves downward and drives the connecting rack 4471 to move downward, the connecting rack 4471 drives the connecting gear 4472 to rotate, thereby driving the active bevel gear 4473 to rotate, the active bevel gear 4473 drives the driven bevel gear 4474 to rotate, and the driven bevel gear 4474 drives the stirring blade 4475 to rotate, thereby performing the initial stirring and mixing of the cleaning agent and the clean water, so that the cleaning agent and the clean water are evenly mixed.

[0101] When the mixed liquid is discharged, the moving tube 442 moves upward and drives the connecting rack 4471 to move upward, the connecting rack 4471 drives the connecting gear 4472 to rotate, thereby driving the active bevel gear 4473 to rotate, the active bevel gear 4473 drives the driven bevel gear 4474 to rotate, and the driven bevel gear 4474 drives the stirring blade 4475 to rotate, thereby stirring and mixing the detergent and clean water again, further improving the uniformity of the mixing.

[0102] In addition, an inner cylinder 4476 is fixedly installed in the inner cavity of the movable tube 442. The inner cavity of the inner cylinder 4476 is funnel-shaped, and a guide groove is provided on the inner wall of the inner cylinder 4476. When the liquid is discharged, the mixed liquid flows to the discharge port of the inner cylinder 4476 through the guide groove. Since the discharge port is small, the mixed liquid is mixed again in the process of passing through the discharge port, thereby further improving the uniformity of the mixing.

[0103] The mixed liquid flows through the inner cylinder 4476 to the dispersion plate 4477. Since a number of through holes are opened on the dispersion plate 4477, the mixed liquid is dispersed and evenly sprayed on the surface of the adsorption smearing body 43. The mixed liquid can be absorbed by the sponge layer. Through the relative rotation of the sponge layer and the drive shaft, the mixed liquid can be evenly smeared on the surface of the drive shaft. Compared with direct spraying on the surface of the drive shaft, the coating will be more comprehensive and uniform, and the splashing of the mixed liquid and the waste caused by it can be avoided, so that the mixed liquid can better contact with the surface of the drive shaft, so as to better decompose oil and dust and improve the cleaning effect.

[0104] In the present invention, by setting the mixing unit 447, the cleaning liquid and clean water can be stirred and mixed multiple times during the process of entering and exiting, which greatly improves the uniformity of the mixed liquid and makes the overall composition of the mixed liquid consistent, thereby ensuring the cleaning effect of the mixed liquid.

[0105] The cleaning assembly 45 includes: a mounting shell 451 fixedly mounted on the moving tube 442; a cleaning brush 454 rotatably mounted on the mounting shell 451; a transmission bevel gear 453 coaxially connected to the cleaning brush 454; a linkage bevel gear 452 meshingly connected to the transmission bevel gear 453, the linkage bevel gear 452 being coaxially connected to the adsorption smear body 43; and a blowing piece 455 for cleaning the cleaning brush 454.

[0106] When the adsorption smear body 43 rolls on the surface of the drive shaft, it can drive the linked bevel gear 452 to rotate, and the linked bevel gear 452 drives the transmission bevel gear 453 to rotate, thereby driving the cleaning brush 454 to rotate. When the cleaning brush 454 rotates, it can brush off the dust on the surface of the drive shaft, so that the mixed liquid directly contacts the surface of the drive shaft, which plays an auxiliary cleaning role and improves the cleaning effect of the oil and dust on the surface of the drive shaft.

[0107] The blowing member 455 includes: a cam 4551 coaxially connected to the cleaning brush 454; a pushing plate 4552 slidably installed in the mounting shell 451, a slide bar fixedly installed on the pushing plate 4552, an directional groove is provided in the mounting shell 451, the slide bar is slidably installed in the directional groove, and the moving direction of the pushing plate 4552 can be limited by the mutual cooperation between the directional groove and the slide bar; an air bag 4553 fixedly installed between the pushing plate 4552 and the mounting shell 451; a connecting spring 4555 that drives the air bag 4553 to reset, one end of the connecting spring 4555 is fixedly connected to the pushing plate 4552, and the other end is fixedly connected to the mounting shell 451; and a jet head 4554 connected to the air bag 4553.

[0108] When the transmission bevel gear 453 rotates, the cam 4551 can be driven to rotate synchronously. When the cam 4551 rotates and abuts against the push plate 4552, the push plate 4552 can be driven to squeeze the airbag 4553 and drive the connecting spring 4555 to be compressed. At this time, the air in the airbag 4553 is squeezed, and the air is ejected through the nozzle 4554 and sprayed on the cleaning brush 454, thereby cleaning the dust attached to the surface of the cleaning brush 454, and the air can be blown onto the drive shaft to blow off the dust on the surface of the drive shaft, further improving the cleaning effect of the drive shaft.

[0109] When the cam 4551 rotates and separates from the push plate 4552, the airbag 4553 can be driven to recover through the elastic force of the connecting spring 4555. At this time, the external air is sucked into the airbag 4553 through the nozzle 4554 to prepare for subsequent use.

[0110] In the present invention, the rotation of the cam 4551 can drive the airbag 4553 to reciprocate in compression and recovery, thereby continuously blowing air to the cleaning brush 454 and the drive shaft, thereby achieving further cleaning of the drive shaft.
