Description

Technical Field

[0001] The invention belongs to the technical field of grinding equipment, in particular to a deburring device for fine grinding of an engine cylinder cover. Background Art

[0002] After the engine cylinder head is processed and formed, there will still be many burrs on its surface. At this time, a grinder is needed. The high-speed rotation of the brush plate on the grinding machine is used to grind and trim the burrs of the engine cylinder head, thereby removing the burrs and achieving the purpose of quickly grinding and processing the engine cylinder head, thereby achieving the purpose of fine processing of the engine cylinder head.

[0003] A Chinese patent application, CN114043373A, discloses an engine cylinder head polishing device. The key technical solution is as follows: the invention achieves a 180-degree rotation of the flip plate through the meshing rotation of the driving gear 1 and the driven gear 1, facilitating the polishing of the upper and lower surfaces of the cylinder head without the need for re-clamping and positioning, thereby improving polishing efficiency.

[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when the grinder is grinding the engine cylinder head, many burrs will be generated during the grinding process, and traditional grinders are difficult to promptly and effectively deal with the burrs generated during grinding, resulting in the continuous accumulation of burrs, thereby affecting the grinding process of the engine cylinder head by the grinder.

[0005] Therefore, the present invention provides a deburring device for fine machining and grinding of an engine cylinder head. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is: the deburring equipment for fine processing and grinding of engine cylinder heads described in the present invention comprises a grinder and a guide rail, the guide rail is fixedly installed inside the grinder, the surface of the guide rail is slidably connected to the grinding main body, the workbench is fixedly installed inside the grinder, the top of the workbench is fixedly installed with the engine cylinder head body; the top of the grinder is fixedly installed with an air pump, the bottom of the air pump is fixedly installed with an air pipe, the interior of the grinder is fixedly connected with a rectangular plate, the air pipe passes through the rectangular plate, and the interior of the air pipe is fixedly installed with a filter screen; when the grinder is grinding the engine cylinder head, many burrs will be generated during grinding, and the traditional grinding It is difficult for the machine to promptly and effectively process the burrs generated during grinding, resulting in the continuous accumulation of burrs during grinding, thereby affecting the grinding process of the engine cylinder head by the grinder. When the present invention is working, when the grinding host is grinding the engine cylinder head body inside the grinder, the air pump is started at the same time to allow the air pump to generate gas and blow it out through the air pipe. At this time, the rectangular plate plays a role of supporting the air pipe. At the same time, the filter screen in the air pipe plays a role of breaking up the gas so that the gas can diffuse, thereby allowing the gas to blow to the surface of the engine cylinder head body, blowing away the burrs on the surface of the engine cylinder head body, so that the burrs will not be concentrated in one place, thereby preventing the burrs from accumulating and affecting the grinding process of the engine cylinder head body by the grinding host.

[0008] Preferably, a sealing ball is slidably connected to one end of the trachea away from the air pump, the center of the sealing ball is outside the trachea, and a plurality of connecting ropes are fixedly connected to the inner wall of the trachea, the other end of the connecting rope is fixedly connected to the sealing ball, and a through groove is provided on one side of the sealing ball; when working, when the gas flows in the trachea, it will push open the sealing ball in the trachea, so that the sealing ball moves away from the trachea through the connecting rope, thereby allowing the gas to flow. At the same time, the round sealing ball plays a role in guiding the gas, so that the gas can be blown to the surroundings, and part of the gas can be directly blown out through the through groove of the sealing ball, thereby achieving a full range of blowing and cleaning. When blowing is not needed, the elastic potential energy of the connecting rope will carry the sealing ball to its original position, thereby closing the port of the trachea, thereby blocking and reducing the entry of dust into the trachea, and preventing dust and impurities from clogging the trachea.

[0009] Preferably, one end of the through slot is rotatably connected to a plurality of cover plates through a torsion spring, and fan blades are fixedly installed inside the through slot; during operation, the gas will first contact the cover plate when blowing the sealing ball, so that the cover plate increases the resistance and facilitates the gas to push the sealing ball. When the gas blows the sealing ball, the cover plate will be pushed open due to the continuous increase in air pressure, so that the gas enters the through slot and blows the fan blades, causing the fan blades to start rotating, thereby dispersing the gas in the through slot and blowing it out in all directions, achieving further diffusion, thereby blowing gas out in all directions to the engine cylinder head body, blowing away the burrs on the engine cylinder head body caused by grinding, and making it more convenient for the grinding host to grind the engine cylinder head body.

[0010] Preferably, a water tank is fixedly installed at the bottom of the rectangular plate, a connecting pipe is fixedly installed at the bottom of the water tank, the other end of the connecting pipe is communicated with the air pipe, a slide groove is provided inside the air pipe, a circular slider is slidably connected inside the slide groove, a sealing plate is slidably connected inside the connecting pipe, an elastic rope is fixedly connected between the sealing plate and the connecting pipe, the slider and the sealing plate are both made of magnet material, a spring is fixedly installed inside the slide groove, and the other end of the spring is fixedly connected to the slider; when working, when the gas flows in the air pipe, it pushes the slider in the slide groove to move, so that the slider moves with the spring The slider starts to slide toward the connecting pipe. At this time, the slider is directly below the connecting pipe. Since both the slider and the sealing plate are made of magnets, the slider will push the sealing plate away from the air pipe, so that the side wall of the sealing plate no longer fits the inner wall of the connecting pipe. At this time, the water pre-installed in the water tank will flow into the air pipe through the connecting pipe, and then be ejected with the gas in the air pipe. After entering the air pipe, the water will be broken up and guided by the filter, fan blades and sealing balls, thereby playing a role in reducing dust and dust pollution. The debris and dust generated during grinding will not fly around at will, reducing the inhalation of workers, thus greatly protecting the workers. When there is no gas flowing in the air pipe, the spring will reset the slider. After the slider is reset, the sealing plate is reset by the elastic rope, thereby re-blocking the connecting pipe, thereby reducing the loss of water.

[0011] Preferably, the opening of the connecting pipe near the water tank is larger, and the opening of the connecting pipe near the air pipe is smaller. The cross-sectional sidewall of the sealing plate is inclined, and the sidewall of the sealing plate is fixedly covered with a rubber ring. When in operation, by making the shape of the connecting pipe match the shape of the sealing plate, the sealing plate can block the connecting pipe when not in use, reducing water leakage. At the same time, the rubber ring plays an auxiliary sealing role, and the ring can also increase friction and position, so that the sealing plate can be fixed more firmly. When the sealing plate is pushed open by the slider due to the same-sex repulsion, water can easily flow out due to the large space at the top of the connecting pipe.

[0012] Preferably, the slider has multiple through-holes extending through one side thereof, and rollers are rotatably connected to the top and bottom of the slider. During operation, the rollers can reduce friction when the slider slides, thereby facilitating sliding. Gas can also be discharged through the through-holes in the slider, so that when a water source is not required, gas can flow without pushing the slider, allowing the air pipe to only be used for blowing.

[0013] Preferably, a hollow elastic ball is fixedly mounted inside the through groove, the elastic ball being made of a waterproof and breathable material, having multiple support rods fixedly mounted inside the elastic ball, and having a heating wire fixedly mounted inside the elastic ball. During operation, after the engine cylinder head body is polished and there is no water in the air pipe, the heating wire in the elastic ball starts to work and emits heat, which then flows out through the waterproof and breathable material and is continuously blown out by the gas. Due to the support rods in the elastic ball, the elastic ball does not deform, and the blown gas is hot air, thereby drying the water stains on the surface of the engine cylinder head body, thereby facilitating the next use of the engine cylinder head body.

[0014] Preferably, the side wall of the grinder is provided with a rectangular groove which passes through the grinder and is inclined, a base with an inclined cross-section is fixedly installed inside the grinder, a rotating rod is rotatably connected to the inside of the grinder through a torsion spring, and a swing ball is fixedly installed on the other end of the rotating rod; when working, the dust and impurities on the engine cylinder head body will fall onto the inclined base after being blown away, and will be guided into the rectangular groove by the base, and when the gas continues to be blown out, it will blow the rotating rod on the inner wall of the grinder, causing the rotating rod to swing into the rectangular groove with the swing ball, and clean the dust and debris in the rectangular groove, thereby achieving the effect of unblocking the rectangular groove.

[0015] Preferably, a push block is slidably connected to the inside of the rectangular groove, and a plurality of arc-shaped plug blocks are fixedly installed on the top and bottom of the push block, and the push block and the swing ball are both made of magnets; when working, when the swing ball rotates, it will attract the push block in the rectangular groove due to its opposite sex, and then drive the push block and the plug block to slide in the rectangular groove, thereby achieving the function of stirring and self-cleaning the rectangular groove, thereby preventing the rectangular groove from being blocked and difficult to discharge sewage in time.

[0016] Preferably, a support rod is fixedly installed at the bottom of the rectangular plate, and the other end of the support rod is fixedly installed to the air pipe; when working, the support rod is installed at the bottom of the rectangular plate to support the air pipe. When supporting the air pipe, the support rod also plays an auxiliary role in supporting the weight of the water tank and the connecting pipe, thereby greatly improving its stability in use. When the grinder vibrates during operation, the air pipe can still maintain relatively stable operation and reduce the occurrence of shaking.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The present invention provides a deburring device for fine machining and grinding of engine cylinder heads. When a grinding host machine is grinding the engine cylinder head body inside the grinder, an air pump is started at the same time to allow the air pump to generate gas and blow it out through an air pipe. At this time, a rectangular plate plays a role in supporting the air pipe. At the same time, a filter screen in the air pipe plays a role in breaking up the gas so that the gas can diffuse, thereby allowing the gas to blow onto the surface of the engine cylinder head body, blowing away the burrs on the surface of the engine cylinder head body, so that the burrs will not be concentrated in one place, thereby preventing the burrs from accumulating and affecting the grinding work of the grinding host machine on the engine cylinder head body.

[0019] 2. The present invention provides a deburring device for fine machining and grinding of engine cylinder heads. When gas flows in the trachea, it pushes the slider in the chute to move, causing the slider to slide toward the connecting pipe with the spring. At this time, the slider is directly below the connecting pipe. Since the slider and the sealing plate are both made of magnets, the slider pushes the sealing plate away from the trachea and slides it, so that the side wall of the sealing plate no longer fits the inner wall of the connecting pipe. At this time, the water pre-installed in the water tank will flow into the trachea through the connecting pipe, and then be ejected with the gas in the trachea. After entering the trachea, the water will be dispersed and guided by the filter screen, fan blades and sealing balls, thereby playing a role in reducing dust and dust pollution. The debris and dust generated during grinding will not fly around at will, reducing the inhalation of workers, thereby greatly protecting the workers. When there is no gas flowing in the trachea, the spring will reset the slider. After the slider is reset, the sealing plate is reset by the elastic rope, thereby re-blocking the connecting pipe, thereby reducing water loss. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1:

[0032] See also Figures 1-6As shown, a deburring device for fine machining and grinding of an engine cylinder head according to an embodiment of the present invention comprises a grinder 1 and a guide rail 2, wherein the guide rail 2 is fixedly installed inside the grinder 1, and a grinding host 3 is slidably connected to the surface of the guide rail 2, a workbench 4 is fixedly installed inside the grinder 1, and an engine cylinder head body 5 is fixedly installed on the top of the workbench 4; an air pump 7 is fixedly installed on the top of the grinder 1, and an air pipe 8 is fixedly installed on the bottom of the air pump 7, a rectangular plate 6 is fixedly connected to the inside of the grinder 1, and the air pipe 8 passes through the rectangular plate 6, and a filter screen 9 is fixedly installed inside the air pipe 8; when the grinder 1 is grinding the engine cylinder head, many burrs will be generated during grinding, and the traditional grinder 1 is difficult to remove them. The burrs generated during grinding are promptly and effectively processed, resulting in the continuous accumulation of burrs during grinding, thereby affecting the grinding process of the engine cylinder head by the grinder 1. When the present invention is working, when the grinding host 3 is grinding the engine cylinder head body 5 inside the grinder 1, the air pump 7 is started at the same time, allowing the air pump 7 to generate gas and blow it out through the air pipe 8. At this time, the rectangular plate 6 plays the role of supporting the air pipe 8. At the same time, the filter screen 9 in the air pipe 8 plays the role of breaking up the gas so that the gas can diffuse, thereby allowing the gas to blow to the surface of the engine cylinder head body 5, blowing away the burrs on the surface of the engine cylinder head body 5, so that the burrs will not be concentrated in one place, thereby preventing the burrs from accumulating and affecting the grinding work of the grinding host 3 on the engine cylinder head body 5.

[0033] The end of the trachea 8 away from the air pump 7 is slidably connected to a blocking ball 10, the center of the blocking ball 10 is outside the trachea 8, and the inner wall of the trachea 8 is fixedly connected to a plurality of connecting ropes 11, the other end of the connecting rope 11 is fixedly connected to the blocking ball 10, and one side of the blocking ball 10 is provided with a through groove 12 running through the trachea 8; when working, when the gas flows in the trachea 8, it will push open the blocking ball 10 in the trachea 8, so that the blocking ball 10 moves away from the trachea 8 through the connecting rope 11, thereby allowing the gas to flow. At the same time, the circular blocking ball 10 plays a role in guiding the gas, so that the gas can be blown to the surroundings, and part of the gas can be directly blown out through the through groove 12 of the blocking ball 10, thereby achieving a full range of blowing and cleaning. When blowing is not needed, the elastic potential energy of the connecting rope 11 will carry the blocking ball 10 to reset, thereby closing the port of the trachea 8, thereby blocking and reducing the entry of dust into the trachea 8, and preventing dust and impurities from clogging the trachea 8.

[0034] One end of the through slot 12 is rotatably connected to a plurality of cover plates 14 through a torsion spring, and a fan blade 13 is fixedly installed inside the through slot 12; during operation, when the gas is blown to the blocking ball 10, it will first contact the cover plate 14, so that the cover plate 14 increases the resistance and facilitates the gas to push the blocking ball 10. After the gas blows the blocking ball 10, the cover plate 14 will be pushed open due to the continuous increase in air pressure, so that the gas enters the through slot 12 and blows the fan blades 13, causing the fan blades 13 to start rotating, thereby dispersing the gas in the through slot 12 and blowing it out in all directions, achieving further diffusion, thereby blowing gas out in all directions to the engine cylinder head body 5, blowing away the burrs on the engine cylinder head body 5 caused by grinding, and making it more convenient for the grinding host 3 to grind the engine cylinder head body 5.

[0035] A water tank 15 is fixedly installed at the bottom of the rectangular plate 6, and a connecting pipe 16 is fixedly installed at the bottom of the water tank 15. The other end of the connecting pipe 16 is communicated with the air pipe 8. A chute 17 is provided inside the air pipe 8. A circular slider 18 is slidably connected to the inside of the chute 17. A sealing plate 19 is slidably connected to the inside of the connecting pipe 16. An elastic rope 20 is fixedly connected between the sealing plate 19 and the connecting pipe 16. Both the slider 18 and the sealing plate 19 are made of magnets. A spring 27 is fixedly installed inside the chute 17, and the other end of the spring 27 is fixedly connected to the slider 18. During operation, when the gas flows in the air pipe 8, it pushes the slider 18 in the chute 17 to move, so that the slider 18 moves The spring 27 slides toward the connecting pipe 16. At this time, the slider 18 is directly below the connecting pipe 16. Since the slider 18 and the sealing plate 19 are both made of magnets, the slider 18 pushes the sealing plate 19 away from the air pipe 8, so that the side wall of the sealing plate 19 no longer fits the inner wall of the connecting pipe 16. At this time, the water pre-installed in the water tank 15 will flow into the air pipe 8 through the connecting pipe 16, and then the gas in the air pipe 8 will be ejected. After entering the air pipe 8, the water will be dispersed and guided by the filter 9, the fan blades 13 and the blocking balls 10, thereby playing a role in reducing dust and dust pollution. The debris and dust generated during grinding will not fly freely, reducing the inhalation of workers, thereby greatly protecting the workers. When there is no gas flowing in the air pipe 8, the spring 27 brings the slider 18 back to its original position. After the slider 18 is reset, the sealing plate 19 is reset by the elastic rope 20, thereby re-blocking the connecting pipe 16, thereby reducing the loss of water.

[0036] The opening of the connecting pipe 16 near the water tank 15 is large, and the opening of the connecting pipe 16 near the air pipe 8 is small. The cross-sectional side wall of the sealing plate 19 is inclined, and the side wall of the sealing plate 19 is fixed with a rubber ring 21. When working, by making the shape of the connecting pipe 16 match the shape of the sealing plate 19, the sealing plate 19 can block the connecting pipe 16 when not in use, reducing its water leakage. At the same time, the rubber ring 21 plays an auxiliary sealing role, and the ring 21 can also play a role in increasing friction and positioning, so that the sealing plate 19 can be fixed more firmly. When the sealing plate 19 is pushed open by the slider 18 due to the same repulsion, the water can easily flow out due to the large space at the top of the connecting pipe 16.

[0037] The slider 18 has multiple through-holes 22 extending through it on one side. Rollers 23 are rotatably connected to the top and bottom of the slider 18. During operation, the rollers 23 reduce friction as the slider 18 slides, facilitating sliding. Gas can also be discharged through the through-holes 22 on the slider 18. When water is not needed, gas can flow without pushing the slider 18, allowing the air pipe 8 to function solely for blowing.

[0038] A hollow elastic ball 24 is fixedly mounted inside the through groove 12. The elastic ball 24 is made of a waterproof and breathable material. A plurality of support rods 25 are fixedly mounted inside the elastic ball 24. A heating wire 26 is fixedly mounted inside the elastic ball 24. During operation, after the engine cylinder head body 5 has been polished and there is no longer any water in the air pipe 8, the heating wire 26 inside the elastic ball 24 begins to operate and emits heat. This heat then flows through the waterproof and breathable material and is continuously blown out by the gas. Due to the support rods 25 inside the elastic ball 24, the elastic ball 24 does not deform, and the blown gas becomes hot air, thereby drying the water stains on the surface of the engine cylinder head body 5, thereby facilitating the next use of the engine cylinder head body 5.

[0039] The side wall of the grinder 1 is provided with a rectangular groove 29 that passes through the grinder 1 and is inclined. A base 28 with an inclined cross-section is fixedly installed inside the grinder 1. A rotating rod 30 is rotatably connected to the inside of the grinder 1 through a torsion spring, and a swing ball 31 is fixedly installed on the other end of the rotating rod 30. During operation, dust and impurities on the engine cylinder head body 5 are blown off and fall onto the inclined base 28, and are guided into the rectangular groove 29 by the base 28. When the gas is continuously blown out, the rotating rod 30 on the inner wall of the grinder 1 is blown, causing the rotating rod 30 to swing into the rectangular groove 29 with the swing ball 31, and clean the dust and debris in the rectangular groove 29, thereby achieving the effect of unblocking the rectangular groove 29.

[0040] A push block 32 is slidably connected to the interior of the rectangular groove 29, and a plurality of arc-shaped insert blocks 33 are fixedly installed on the top and bottom of the push block 32. The push block 32 and the swing ball 31 are both made of magnets. When working, when the swing ball 31 rotates, it will attract the push block 32 in the rectangular groove 29 due to its opposite polarity, thereby driving the push block 32 and the insert block 33 to slide in the rectangular groove 29, thereby achieving the function of stirring and self-cleaning the rectangular groove 29, thereby preventing the rectangular groove 29 from being blocked and making it difficult to discharge sewage in time.

[0041] Example 2:

[0042] like Figure 7 As shown in Comparative Example 1, another embodiment of the present invention is:

[0043] A support rod 34 is fixedly installed at the bottom of the rectangular plate 6, and the other end of the support rod 34 is fixedly installed to the air pipe 8. During operation, by installing the support rod 34 at the bottom of the rectangular plate 6, the support rod 34 supports the air pipe 8. When supporting the air pipe 8, the support rod 34 also helps to support the weight of the water tank 15 and the connecting pipe 16, thereby greatly improving its stability in use. When the grinder 1 vibrates during operation, the air pipe 8 can still maintain relatively stable operation and reduce the occurrence of shaking.

[0044] Working principle: When the grinding host 3 is grinding the engine cylinder head body 5 inside the grinder 1, the air pump 7 is started at the same time, allowing the air pump 7 to generate gas and blow it out through the air pipe 8. At this time, the rectangular plate 6 plays the role of supporting the air pipe 8. At the same time, the filter screen 9 in the air pipe 8 plays the role of breaking up the gas so that the gas can diffuse, so that the gas can be blown to the surface of the engine cylinder head body 5, and the burrs on the surface of the engine cylinder head body 5 are blown away, so that the burrs will not be concentrated in one place, thereby preventing the burrs from accumulating and affecting the grinding work of the grinding host 3 on the engine cylinder head body 5. When the gas flows in the air pipe 8, it will push open the sealing ball 10 in the air pipe 8, so that the sealing ball 10 moves away from the air pipe 8 through the connecting rope 11, thereby allowing the gas to flow. At the same time, the circular sealing ball 10 plays the role of guiding the gas, so that the gas can be blown around, and part of the gas can be directly blown out through the through groove 12 of the sealing ball 10, thereby achieving a full range of blowing and cleaning. When blowing is not needed, the elastic potential energy of the connecting rope 11 will bring the sealing ball 10 back to its original position, thereby closing the port of the trachea 8, and then playing a role in blocking and reducing dust from entering the trachea 8, and preventing dust and impurities from clogging the trachea 8. When the gas blows the sealing ball 10, it will first contact the cover plate 14, allowing the cover plate 14 to increase the resistance and facilitate the gas to push the sealing ball 10. After the gas blows the sealing ball 10, the cover plate 14 will be pushed open due to the continuous increase in air pressure, allowing the gas to enter the through groove 12 and blow the fan blades 13, causing the fan blades 13 to start rotating, thereby dispersing the gas in the through groove 12 and blowing it out in all directions, achieving further diffusion, thereby blowing gas out in all directions to the engine cylinder head body 5, blowing away the burrs on the engine cylinder head body 5 caused by grinding, and making it more convenient for the grinding host 3 to grind the engine cylinder head body 5.

[0045] When the gas flows in the trachea 8, it will push the slider 18 in the slide groove 17 to move, so that the slider 18 slides in the direction of the connecting pipe 16 together with the spring 27. At this time, the slider 18 is directly below the connecting pipe 16. Since the slider 18 and the sealing plate 19 are both made of magnets, the slider 18 will push the sealing plate 19 to slide away from the trachea 8, so that the side wall of the sealing plate 19 no longer fits the inner wall of the connecting pipe 16. At this time, the water pre-installed in the water tank 15 will flow into the trachea 8 through the connecting pipe 16, and then be ejected with the gas in the trachea 8. After entering the trachea 8, the water will be broken up and guided by the filter screen 9, fan blades 13 and sealing balls 10, thereby playing a role in dust reduction and reducing dust pollution, so that the debris and dust generated during grinding will not fly around at will, reducing the inhalation of the staff, thereby greatly protecting the staff. When there's no air flowing through the trachea 8, spring 27 pulls slider 18 back into position. After slider 18 returns to its original position, sealing plate 19 is pulled back into position by elastic cord 20, resealing connecting tube 16 and reducing water loss. By matching the shape of connecting tube 16 with the shape of sealing plate 19, sealing plate 19 can block connecting tube 16 when not in use, reducing water leakage. A rubber ring 21 also acts as an auxiliary seal, increasing friction and positioning, making sealing plate 19 more securely fixed. When sealing plate 19 is again pushed open by slider 18 due to the repulsive forces of the same polarity, water can easily flow out due to the large space at the top of connecting tube 16. Rollers 23 are installed on slider 18 to reduce friction as it slides, facilitating its sliding. Gas can also be discharged through through-holes 22 on slider 18. When water is not needed, gas can flow without pushing slider 18, allowing trachea 8 to function solely as a blower. After the grinding process of the engine cylinder head body 5 is completed and there is no water source in the air pipe 8, the heating wire 26 in the elastic ball 24 starts to work and emits heat. At this time, the heat will flow out through the waterproof and breathable material and be continuously blown out by the gas. Due to the support rod 25 in the elastic ball 24, the elastic ball 24 will not be deformed, and the blown gas will be hot air, thereby drying the water stains on the surface of the engine cylinder head body 5, making it easier to use the engine cylinder head body 5 in the next step.

[0046] The dust and impurities on the engine cylinder head body 5 will fall onto the inclined base 28 after being blown away, and will be guided into the rectangular groove 29 by the base 28. When the gas continues to be blown out, it will blow the rotating rod 30 on the inner wall of the grinder 1, causing the rotating rod 30 to swing into the rectangular groove 29 with the swing ball 31, and clean the dust and debris in the rectangular groove 29, thereby achieving the effect of unblocking the rectangular groove 29. When the swing ball 31 rotates, it will attract the push block 32 in the rectangular groove 29, and then drive the push block 32 and the insert block 33 to slide in the rectangular groove 29, thereby achieving the effect of stirring and self-cleaning the rectangular groove 29, thereby preventing the rectangular groove 29 from being blocked and difficult to discharge sewage in time.
