Description

Technical Field

[0001] This invention relates to the field of engine cover edge processing, specifically to an engine cover edge trimming device. Background Technology

[0002] The engine cover edge trimming device is a trimming device used to smooth the edges of the engine cover. After clamping the engine cover with a clamping fixture, the engine cover edge trimming device uses a grinding wheel to grind and trim the edges of the engine cover, thereby completing the trimming process.

[0003] In the existing technology, after the engine cover is processed and formed, burrs will appear on the edge of the engine cover, which needs to be polished and repaired. When polishing the edge of the round engine cover, the engine cover is clamped and moved to the grinding wheel through automation. The rotation of the grinding wheel is used to polish and repair the edge of the engine cover. When the engine cover is finely repaired, whether the surface is polished too deeply or too shallowly, it will affect the quality of the engine cover.

[0004] While using a grinder to polish the edges of the engine cover achieves automation and solves the problem of uneven edges caused by manual angle control and low precision, it only involves fine polishing a local area of ​​the engine cover before switching positions. It cannot achieve uniform polishing of the entire engine cover. Due to external factors or prolonged use of the grinder, the polishing quality may differ from the initial polishing, thus affecting the flatness of the engine cover edges.

[0005] Based on the above-mentioned shortcomings, it is necessary to propose improvement measures to address these problems. The present invention provides an engine cover edge trimming device. Summary of the Invention

[0006] The purpose of this invention is to provide an engine cover edge trimming device, which achieves multi-angle grinding and trimming of the engine cover edge through rotational adaptive method.

[0007] An engine cover edge trimming device includes an engine cover, a feed inlet, a vent, and a housing. It also includes a trimming assembly and a clamping assembly. The housing has a vent at its top, allowing external air to enter and remove heat generated during engine cover grinding. Simultaneously, it blows off debris generated during grinding, preventing debris from affecting subsequent trimming. The engine cover is placed inside the housing. A feed inlet is installed on the front of the housing. During grinding and trimming, the engine cover is placed into the device through the feed inlet. The trimming assembly is installed inside the housing and adapts to different engine cover sizes by changing its internal position. The trimming assembly trims the engine cover... The engine cover edge is ground and trimmed at multiple angles. The trimming component can simultaneously grind engine covers of different sizes. After coarse grinding, the trimming component performs fine grinding on the engine cover edge, removing burrs and making the edge smooth. A clamping component is installed near the trimming component. The clamping component stabilizes the trimming component by converting curved motion into linear motion. The drive rod in the clamping component moves from a curved motion to a linear motion, causing the drive rod to move the pressure block downward, thereby clamping the engine cover and improving the grinding effect. The clamping component clamps the engine cover as it rises, and at the same time, shakes off the debris generated during the grinding and trimming of the engine cover edge to prevent it from affecting the grinding and trimming of the next engine cover.

[0008] The clamping assembly includes a motor, a collecting plate, a movable cylinder, an unfolding rod, a clamping plate, and a sleeve. A motor is fixedly installed at the bottom of the outer casing. Shock-absorbing pads are installed on the motor and the bottom of the outer casing to prevent vibration of the outer casing from causing the telescopic cylinder to extend. Simultaneously, it prevents the engine cover, placed on the positioning clamping plate, from falling due to vibration during its ascent. The motor output shaft has external threads, and the inner wall of the sleeve has internal threads for a stabilizing pressure block. Driven by the motor, the drive rod presses down on the pressure block to stabilize the sleeve. The motor rotation causes the sleeve to rise, thus unfolding the collecting assembly to collect waste materials generated during grinding and finishing. Simultaneously, the rotation of the sleeve causes the engine cover to rotate, contacting the grinding wheel for grinding and finishing. The motor output shaft is threadedly connected to a sleeve for unfolding the collecting plate. The motor rotation causes the sleeve to rise, unfolding the collecting plate to collect waste materials generated during the grinding of the engine cover. A clamping plate is fixedly installed at the top of the sleeve. An engine cover is placed on a plate. Driven by a motor, the engine cover is fixed and positioned by abutment blocks and clamps to prevent misalignment during grinding, which would affect the grinding effect. A movable cylinder is threadedly connected to the sleeve, and a fixed rod is rotatably connected to the movable cylinder. The fixed rod is rotatably connected to an unfolding rod that stabilizes the engine cover. As the movable cylinder rises, it drives the collecting plate to unfold. Simultaneously, the unfolding plate moves as it rises, causing the movable rod to move and stabilize the engine cover, preventing it from shaking during grinding and falling off the clamps, which would also affect the grinding effect. The unfolding rod is rotatably connected to the collecting plate. Driven by the sleeve, the unfolding rod rises, causing the collecting plate to unfold and collect the waste generated during grinding and finishing of the engine cover. The collecting plate has concave collection grooves to facilitate the collection of waste after grinding the engine cover.

[0009] The finishing assembly includes a fixed cylinder, a telescopic cylinder, a grinding wheel, a connecting rod, a fixed rod, a pawl, and a ratchet. Four fixed cylinders are evenly arranged on the inner wall of the outer casing. Each fixed cylinder is slidably connected to a telescopic cylinder, allowing the grinding assembly to adapt to the shape of the engine cover during grinding. The telescopic cylinder has semi-circular grooves on both sides for adaptive grinding, allowing the connecting rod to expand and contract during grinding, thus adapting to the shape of the engine cover. A ratchet is mounted on the upper side of the grinding wheel, rotating coaxially with it and connected by a coupling to ensure synchronous movement. The ratchet controls the rotation of the grinding wheel. A pawl is mounted on the upper side of the grinding wheel; when the motor rotates forward, the ratchet and pawl fix the grinding wheel, preventing rotation during grinding and performing rough grinding of the engine cover. When the motor reverses, the engine cover rotates under the action of the ratchet and pawl, causing the telescopic cylinder to self-adaptively grind. At the same time, the grinding wheel starts to rotate, thus achieving the finishing of the engine cover edge. The grinding wheel is equipped with a pawl on its upper side, which controls the rotation of the ratchet. When the motor rotates forward, the pawl engages the ratchet, causing the engine cover to be coarsely ground. When the motor reverses, the pawl moves, causing the grinding wheel to move, so that the engine cover rotates while the grinding wheel also rotates, performing fine grinding on the engine cover. The electric telescopic rod is installed inside the telescopic cylinder. The electric telescopic rod pushes the telescopic cylinder to move, causing the grinding wheels on both sides to extend and retract towards the middle position, grinding the edges of the engine cover. The upper side of the telescopic cylinder is equipped with a clamping block that clamps and positions the engine cover. Driven by the drive rod, the clamping block moves, causing the clamping block and the clamping plate to clamp the engine cover together, while positioning the engine cover to prevent misalignment during grinding, which would result in poor grinding effect.

[0010] Preferably, an arc-shaped rod is installed on the upper side of the collecting plate. When the motor rotates forward, the arc-shaped rod guides the waste debris generated during the grinding of the engine cover, preventing the waste debris from scattering into the interior of the outer casing and causing damage. A groove is provided on the lower side of the collecting plate. When the engine cover rotates backward, the waste debris generated during grinding falls into the groove of the collecting plate. The collecting plate is at an angle of 120°–150° to the unfolding rod, thus preventing collisions between the collecting plate and the unfolding rod during their expansion and contraction, which would affect the adaptive grinding of the engine cover. This ensures that the unfolding of the collecting plate is smooth and controllable, improving the collection efficiency of waste debris generated during engine cover grinding and finishing. Simultaneously, it allows the collecting assembly to unfold quickly, cooperating with the clamping assembly to clamp the engine cover, further improving the grinding efficiency of the engine cover. When the collecting plate unfolds, it will not collide with the unfolding rod of the grinding component, thus affecting the grinding effect. It also slows down the speed at which the unfolding component retracts when the motor reverses, preventing waste from scattering into the outer casing. If the angle between the collecting plate and the unfolding rod is less than 120°, the collecting plate will collide with the extension and retraction of the unfolding rod of the grinding component during the engine cover's as it rises, preventing the collecting plate from fully extending. This also affects the grinding speed of the grinding component, reducing the grinding and finishing effect on the edges of the engine cover. If the angle between the collecting plate and the unfolding rod is greater than 150°, the collecting plate will interfere with the motor's shaft, causing the engine cover to wobble. This is not conducive to the positioning of the engine cover, causing it to fall off the first baffle. Furthermore, during grinding of the engine cover, the displacement of the engine cover's position means that the edges of the engine cover cannot be completely ground.

[0011] A movable rod is rotatably connected to the upper side of the collecting plate. Driven by a motor, the movable rod moves, causing the collecting plate to unfold and collect the debris generated during the grinding of the engine cover. This prevents the debris from damaging the grinding device. A left-right swinging connecting rod is rotatably connected to the left side of the movable rod. When the movable rod rises, it applies an upward force to the connecting rod, while the support frame applies a downward force to the connecting rod. This causes the connecting rod to swing left and right, stabilizing the pressure block and causing the pressure block to move down to clamp the engine cover. A support frame is rotatably connected to the upper side of the connecting rod, and a drive rod is rotatably connected to the right side of the connecting rod to push the pressure block to clamp the engine cover. The connecting rod applies a downward force to the drive rod, causing the drive rod to move down and lower the pressure block, thus clamping the engine cover and preventing misalignment during grinding. This design also accommodates engine covers of different sizes for clamping and fixing.

[0012] The telescopic cylinder is rotatably connected to an adaptive grinding connecting rod at its top center. During the initial grinding of the engine cover, the connecting rod remains stationary. Under the push of the electric telescopic rod, the telescopic cylinder moves to grind and trim engine covers of different sizes, thereby improving the adaptability of the trimming component. The connecting rods form a diamond structure with each other. The movement of the rear telescopic cylinder, connected by the connecting rod, causes the other three telescopic cylinders to move to grind and trim the engine cover. At the same time, it can grind and trim the edges of the engine cover from multiple angles to prevent poor edge grinding.

[0013] The bottom of the grinding wheels on both the front and rear sides is angled to accommodate engine covers of different sizes. The angled bottom of the grinding wheels is used to fix the engine cover of different sizes. At the same time, the angled bottom of the grinding wheels performs preliminary grinding on the edges of the engine cover. The angled bottom of the grinding wheels also enhances the finishing effect on the engine cover. The angled bottom of the grinding wheels applies axial force to move the engine cover smoothly. When the engine cover is raised, the angled bottom of the grinding wheels protects the engine cover and prevents it from vibrating during the rise, which could cause the engine cover to fall off.

[0014] The grinding wheel has grooves in its inner ring for grinding the upper and lower edges of the engine cover. Since the thickness of the engine cover and the grinding wheel are not identical, the edges of the engine cover may not be ground properly. When the engine cover rotates, the grooves in the inner ring of the grinding wheel grind the edges of the engine cover, preventing the surface of the engine cover from being ground but the edges remaining unground. The grooves and the pressure block have evenly spaced convection holes for heat dissipation, thus improving the lifespan of the grinding wheel and reducing the need for frequent wheel replacements, which would reduce work efficiency. Simultaneously, the convection holes in the grooves and the pressure block enhance gas flow, improving the grinding effect on the engine cover under atmospheric pressure.

[0015] The beneficial effects of this invention are:

[0016] 1. The present invention provides an engine cover edge trimming device, which realizes multi-angle grinding and trimming of the engine cover edge through rotational adaptive method. The trimming component performs multi-angle grinding on the engine cover edge, and the clamping component stabilizes the trimming component by converting curved motion into linear motion, thereby improving the grinding accuracy and efficiency.

[0017] 2. The present invention provides an engine cover edge trimming device, which uses trimming components to grind the engine cover edge at multiple angles, and clamping components to collect the waste generated during the engine cover grinding and trimming, thereby improving the grinding quality.

[0018] 3. The present invention provides an engine cover edge trimming device. This device uses a rotating unfolding method to adapt to different specifications of engine covers by changing the internal position of the trimming components. By changing the movement mode, it can perform coarse and fine grinding on the engine cover, thereby improving the versatility of the device for grinding. Attached Figure Description

[0030] Example: An engine cover 2 edge trimming device includes an engine cover 2, a vent 11, and a housing 1. It also includes a trimming assembly 5 and a clamping assembly. The housing 1 has a vent 11 at its top. External air enters the housing 1 through the vent 11, removing heat generated during engine cover 2 grinding and blowing off debris generated during grinding, preventing debris from affecting subsequent trimming. The engine cover 2 is placed inside the housing 1. A feed inlet 12 is installed on the front of the housing 1. During grinding and trimming, the engine cover 2 is placed into the device through the feed inlet 12. The trimming assembly 5 is installed inside the housing 1. The trimming assembly 5 adapts to different engine cover 2 sizes by changing its internal position. The trimming assembly 5... The engine cover 2 edge is ground and trimmed at multiple angles. The trimming component 5 can grind engine covers 2 of different sizes at the same time. After coarse grinding, the trimming component 5 performs fine grinding on the edge of the engine cover 2, which removes the burrs on the edge of the engine cover 2 and makes the edge of the engine cover 2 smooth. A clamping component is installed near the trimming component 5. The clamping component uses the method of converting curved motion into linear motion to stabilize the trimming component 5. The drive rod 42 in the clamping component moves from curved motion to linear motion, which drives the drive rod 42 to move the pressure block 54 downward, thereby clamping the engine cover 2 and improving the grinding effect. The clamping component clamps the engine cover 2 during the process of the engine cover 2 rising. At the same time, the clamping component shakes off the waste from the grinding and trimming of the edge of the engine cover 2 to prevent it from affecting the grinding and trimming of the next engine cover 2.

[0031] The clamping assembly includes a motor 31, a collecting plate 32, a moving cylinder 33, an unfolding rod 34, a clamping plate 35, and a sleeve 36. The motor 31 is fixedly mounted on the bottom of the outer casing 1. Shock-absorbing pads are installed on the motor 31 and the bottom of the outer casing 1 to prevent vibration of the outer casing 1 from causing the telescopic cylinder 52 to extend. Simultaneously, it prevents the engine cover 2, placed on the positioning clamping plate 35, from falling due to vibration during its ascent. The output shaft of the motor 31 has external threads, and the inner wall of the sleeve 36 has internal threads for a stabilizing pressing block 54. Driven by the motor 31, the sleeve 36 drives the rod 4... 2. Pressing down stabilizes the pressure block 54. The motor 31 rotates, causing the sleeve 36 to rise, thereby unfolding the collection component to collect the waste debris generated during grinding and finishing. Simultaneously, the rotation of the sleeve 36 causes the engine cover 2 to rotate, contacting the grinding wheel 53 for grinding and finishing. The output shaft of the motor 31 is threadedly connected to the sleeve 36 for unfolding the collection plate 32. The rotation of the motor 31 causes the sleeve 36 to rise, unfolding the collection plate 32 and collecting the waste debris generated during the grinding of the engine cover 2. A clamping plate 35 is fixedly installed on the top of the sleeve 36. An engine cover 2 is placed on a clamping plate 35. Driven by a motor 31, the engine cover 2 is fixed and positioned by a pressing block 54 and a clamping plate 35 to prevent misalignment during grinding, which would affect the grinding effect. A sleeve 36 is threadedly connected to a movable cylinder 33, which is rotatably connected to a fixed rod 37. The fixed rod 37 is rotatably connected to an unfolding rod 34 that stabilizes the engine cover 2. As the movable cylinder 33 rises, it causes the collecting plate 32 to unfold. Simultaneously, the unfolding plate's rise causes the movable rod 44 to move. The movement of the moving rod 44 stabilizes the engine cover 2, preventing it from shaking during polishing and potentially detaching from the clamping plate 35, thus affecting the polishing effect. The unfolding rod 34 is rotatably connected to the collecting plate 32. Driven by the sleeve 36, the unfolding rod 34 rises, causing the collecting plate 32 to unfold and collect the waste generated during polishing of the engine cover 2. The collecting plate 32 has a concave collecting groove 321 to facilitate the collection of waste after polishing the engine cover 2.

[0032] In the prior art, when grinding and finishing the engine cover 2, after grinding the edges of the engine cover 2, a grinding rod is used manually to grind and finish the edges of the engine cover 2. The grinding is done on one side only, and the grinding angle of the engine cover 2 cannot be controlled during the grinding process, resulting in uneven edges when the engine cover 2 is ground. In this invention, the engine cover 2 is rotated while the grinding wheel 53 does not rotate for rough grinding. After the engine cover 2 is rough ground, the edges of the engine cover 2 are finished. At the same time, the edges of the engine cover 2 can be ground simultaneously during the grinding and finishing process.

[0033] The finishing assembly 5 includes a fixed cylinder 51, a telescopic cylinder 52, a grinding wheel 53, a connecting rod 6, a fixing rod 37, a pawl 56, and a ratchet 55. The fixed cylinders 51 are evenly arranged on the inner wall of the outer casing 1, with four cylinders 51 evenly distributed on the inner wall. The fixed cylinders 51 are slidably connected to the telescopic cylinders 52, allowing the grinding assembly to adapt to the properties of the engine cover 2 during grinding by extending and retracting the telescopic cylinders 52. The telescopic cylinders 52 have semi-circular grooves on both sides to achieve adaptive grinding, allowing the engine cover 2 to grind during grinding. The connecting rod 6 extends and retracts, thus adapting to the shape of the engine cover 2 for grinding. A ratchet 55 is mounted on the upper side of the grinding wheel 53, and the ratchet 55 rotates coaxially with the grinding wheel 53. They are connected by a coupling, allowing the ratchet 55 and grinding wheel 53 to move synchronously. The rotation of the grinding wheel 53 is controlled by the ratchet 55. A pawl 56 is mounted on the upper side of the grinding wheel 53. When the motor 31 rotates forward, the ratchet 55 and pawl 56 fix the grinding wheel 53, preventing it from rotating during grinding of the engine cover 2. This allows for rough grinding of the engine cover 2. When motor 31 reverses, under the action of ratchet 55 and pawl 56, the engine cover 2 rotates, driving the telescopic cylinder 52 to perform adaptive grinding. At the same time, the grinding wheel 53 starts to rotate, thereby achieving the finishing of the edge of the engine cover 2. Pawl 56 is installed on the upper side of the grinding wheel 53, and pawl 56 controls the rotation of ratchet 55. When motor 31 rotates forward, pawl 56 engages ratchet 55, causing the engine cover 2 to perform coarse grinding. When motor 31 reverses, pawl 56 moves, causing grinding wheel 53 to move, so that the engine cover 2 rotates while grinding wheel 53 also rotates, performing fine grinding on the engine cover 2. The electric telescopic rod 57 is installed inside the telescopic cylinder 52. The electric telescopic rod 57 pushes the telescopic cylinder 52 to move, thereby causing the grinding wheels 53 on the front and rear sides to extend and retract towards the middle position to grind the edges of the engine cover 2. A pressure block 54 is installed on the upper side of the telescopic cylinder 52 to clamp and position the engine cover 2. The pressure block 54 moves under the drive of the drive rod 42, thereby causing the pressure block 54 and the clamping plate 35 to clamp the engine cover 2 together, and at the same time to position the engine cover 2 to prevent the engine cover 2 from being misaligned during grinding, which would result in poor grinding effect of the engine cover 2.

[0034] An arc-shaped rod is installed on the upper side of the collecting plate 32. When the motor 31 rotates forward, the arc-shaped rod guides the waste generated during the grinding of the engine cover 2, preventing the waste from falling into the interior of the outer shell 1 and causing damage. A groove is provided on the lower side of the collecting plate 32. When the engine cover 2 rotates backward, the waste generated during grinding falls into the groove of the collecting plate 32. The collecting plate 32 is at an angle of 120°–150° to the unfolding rod 34, thus preventing collisions between the collecting plate 32 and the unfolding rod 34 during their unfolding and retraction, which would affect the adaptive grinding of the engine cover 2. This ensures that the unfolding of the collecting plate 32 is smooth and controllable, improving the collection efficiency of waste generated during the grinding and finishing of the engine cover 2. Simultaneously, it allows the collecting assembly to unfold quickly, cooperating with the clamping assembly to clamp the engine cover 2, further improving the grinding efficiency of the engine cover 2. When unfolded, it will not collide with the unfolding rod 34 of the grinding component, thus affecting the grinding effect. It slows down the speed at which the unfolding component retracts when the motor 31 reverses, so that waste chips will not fall into the outer shell 1. The angle between the collecting plate 32 and the unfolding rod 34 is less than 120°. During the process of the engine cover 2 rising, the collecting plate 32 collides with the extension and retraction of the unfolding rod 34 of the grinding component, thus preventing the collecting plate 32 from extending. At the same time, the grinding speed of the grinding component is affected, thus reducing the grinding and finishing effect on the edge of the engine cover 2. The angle between the collecting plate 32 and the unfolding rod 34 is greater than 150°. The collecting plate 32 interferes with the rotating shaft of the motor 31, thus causing the engine cover 2 to shake. This is not conducive to the positioning of the engine cover 2, causing the engine cover 2 to fall off the first baffle. At the same time, when grinding the engine cover 2, the displacement of the engine cover 2 position means that the edge of the engine cover 2 cannot be completely ground.

[0035] The clamping plate 35 is made of materials including but not limited to aluminum alloy. The aluminum alloy clamping plate 35 has good friction performance. The positioning clamping plate 35 and the clamping plate 35 clamp the engine cover 2. The engine cover 2 will not slip when it is rotated and polished. At the same time, the aluminum alloy clamping plate 35 has high rigidity, so the clamping plate 35 is not easy to deform during the clamping process of the engine cover 2, thereby avoiding deformation of the clamping plate 35 during the polishing process of the engine cover 2, and thus preventing the engine cover 2 from falling off.

[0036] A movable rod 44 is rotatably connected to the upper side of the collecting plate 32. Driven by the motor 31, the movable rod 44 moves, thereby causing the collecting plate 32 to unfold and collect the waste generated during the grinding of the engine cover 2, preventing the waste generated during the grinding of the engine cover 2 from damaging the grinding device. A left-right swinging connecting rod 43 is rotatably connected to the left side of the movable rod 44. When the movable rod 44 rises, it gives the connecting rod 43 an upward force, while the support frame 45 gives the connecting rod 43 a downward force, thereby causing the connecting rod 43 to swing left and right against the pressing block 54. The mechanism stabilizes the engine cover 2 and causes the pressure block 54 to move downwards to clamp it. A support frame 45 is rotatably connected to the upper side of the connecting rod 43, and a drive rod 42 is rotatably connected to the right side of the connecting rod 43 to push the pressure block 54 to clamp the engine cover 2. The connecting rod 43 applies a downward force to the drive rod 42, which in turn moves the drive rod 42 downwards, causing the pressure block 54 to move downwards and clamp the engine cover 2. This prevents the engine cover 2 from shifting during grinding and can also accommodate engine covers 2 of different sizes for clamping and fixing.

[0037] The top center of the telescopic cylinder 52 is rotatably connected to an adaptive grinding connecting rod 6. When the engine cover 2 is initially ground, the connecting rod 6 remains stationary. Under the push of the electric telescopic rod 57, the telescopic cylinder 52 moves to grind and trim engine covers 2 of different specifications, thereby improving the adaptability of the trimming component 5. The connecting rods 6 form a diamond structure with each other. The movement of the telescopic cylinder 52 on the rear side, connected by the connecting rod 6, causes the other three telescopic cylinders 52 to move to grind and trim the engine cover 2. At the same time, it can grind and trim the edges of the engine cover 2 from multiple angles to prevent poor grinding of the edges of the engine cover 2.

[0038] The bottom of the front and rear grinding wheels 53 is designed to accommodate the angles of different sized engine covers 2. The angles at the bottom of the grinding wheels 53 are used to fix the engine covers 2 of different sizes. At the same time, the angles at the bottom of the grinding wheels 53 perform preliminary grinding on the edges of the engine covers 2. The angles at the bottom of the grinding wheels 53 also enhance the finishing effect on the engine covers 2. The angles at the bottom of the grinding wheels 53 apply axial force to move the engine covers 2 smoothly. When the engine covers 2 are raised, the angles at the bottom of the grinding wheels 53 protect the engine covers 2 and prevent the engine covers 2 from vibrating during the rise, which could cause the engine covers 2 to fall off.

[0039] The grinding wheel 53 has a groove 531 in the middle ring for grinding the upper and lower edges of the engine cover 2. The engine cover 2 and the grinding wheel 53 have different thicknesses, which may cause the edges of the engine cover 2 to be un-grinded. When the engine cover 2 rotates, the groove 531 in the middle ring of the grinding wheel 53 can grind the edges of the engine cover 2, preventing the surface of the engine cover 2 from being ground but the edges not being ground. The groove 531 and the pressing block 54 have mutually convection through holes, which dissipate heat from the grinding wheel 53 and the pressing block 54, thereby improving the life of the grinding wheel 53 and avoiding the need for the operator to replace the grinding wheel 53 frequently, thus reducing work efficiency. At the same time, the mutually convection through holes in the groove 531 and the pressing block enhance the airflow and enhance the grinding of the engine cover 2 under atmospheric pressure.

[0040] After the engine cover 2 is manufactured, its edges need to be ground and finished. The engine cover 2 is placed on a clamping plate 35, and a sleeve 36 is fixedly connected to the bottom of the clamping plate 35. The sleeve 36 has an internal thread, and the output shaft of the motor 31 has an external thread. The output shaft of the motor 31 is threaded to the sleeve 36, so that the motor 31 rotates forward, driving the sleeve 36 to rise, which in turn causes the clamping plate 35 to rise. The clamping plate 35 and the pressing block 54 clamp the engine cover 2 and position it. The clamping plate 35 stops rising, and the clamping plate 35 and the pressing block 54 cooperate to clamp the engine cover 2. Then the sleeve 36 rotates, causing the engine cover 2 to rotate accordingly. The finishing component 5 grinds and finishes the engine cover 2, making its edges smooth. At the same time, the air reciprocates, bringing external air into the outer casing 1 to dissipate heat during the grinding of the engine cover 2 and prevent the waste generated during grinding and finishing from adhering to the engine cover 2, which would affect subsequent engine... The grinding and finishing of the top cover 2 has an impact. The electric telescopic rod 57 pushes the telescopic cylinder 52 to move, thereby realizing the expansion and contraction of the moving rod 44 to grind the edge of the engine top cover 2. At the same time, the edge of the engine top cover 2 has protrusions. The multi-angle grinding of the engine top cover 2 grinds and finishes the edge of the engine top cover 2. The collecting plate 32 unfolds to collect the waste from the grinding of the engine top cover 2. The unfolding of the collecting plate 32 causes the moving rod 44 to move, which causes the connecting rod 43 to move left and right. This causes the drive rod 42 to be subjected to a downward force, which drives the pressing block 54 to move down, fixing and positioning the engine top cover 2. The grinding wheel 53 in the finishing component 5 also rotates. After the rough grinding of the edge of the engine top cover 2, the grinding wheel 53 in the finishing component 5 does not move when the edge of the engine top cover 2 is rough ground. When the edge of the engine top cover 2 is finely ground, the grinding wheel 53 in the finishing component 5 moves. The engine top cover 2 also rotates under the drive of the motor 31, making the edge of the engine top cover 2 smooth and flat.
