Description

Technical Field

[0001] This invention relates to the field of turning technology, and in particular to a groove turning machine for producing motorcycle pulleys. Background Technology

[0002] Motorcycles are motorized vehicles with two or three wheels, powered by a motor. Their core characteristics are lightness, agility, rapid acceleration, easy parking, and low cost, making them suitable for commuting, transportation, recreation, and long-distance travel. Motorcycle transmission systems can be broadly classified into three categories: chain drive, belt drive, and shaft drive. The pulley is a crucial component in belt drives; its production requires machining the groove shape, necessitating the use of machining equipment.

[0003] For example, Chinese Patent Publication No. CN215468112U describes a device suitable for turning pulleys, including a lathe housing. A motor is located in the middle of the left side of the lathe housing, and a rotating shaft is fixedly connected to the right end of the motor. The rotating shaft passes through the side wall of the lathe housing, and its right end is fixedly connected to the middle of the left side of a fixed plate. A fixing rod is fixedly connected to the middle of the right side of the fixed plate. A water inlet pipe is located at the upper end of the lathe housing, and a water nozzle is rotatably connected to the front end of the water inlet pipe. A water storage tank is located on the inner bottom wall of the lathe housing corresponding to the position of the upper water nozzle. A screen is fixedly connected to the middle of the inner side wall of the water storage tank, and a drain pipe is located on the right side of the bottom end of the water storage tank. The front end of the inner bottom wall of the lathe housing is connected by a mechanical... A third base is slidably connected to the slide rail. The top of the third base is slidably connected to a second base via a mechanical slide rail. A limit sleeve is fixedly connected to the top of the second base. The limit sleeve has evenly distributed openings at its top. A central column is rotatably connected inside the limit sleeve. Evenly distributed locking rods are fixedly connected to the outer side of the central column at positions corresponding to the openings. A clamping seat is fixedly connected to the top of the central column. The right end of the inner bottom wall of the lathe housing is slidably connected to a first base via a mechanical slide rail. A top rod is fixedly connected to the top left side of the first base. By rotating the fixed disc with a motor, the pulley rotates with the fixed rod. At this time, by moving the second base in front, the cutting tool contacts the pulley, thereby completing the turning of the pulley.

[0004] In existing technical references, the rotation of a pulley can be used to machine the pulley with a cutting tool. However, with this design, the cutting tool generates a large amount of ribbon-like waste chips during machining, which easily get tangled on the cutting tool. This not only affects the machining process but can also cause the tool to break in severe cases. Furthermore, the tangled ribbon-like waste chips can scratch the surface of the pulley, affecting the machining accuracy. Summary of the Invention

[0005] To solve the above technical problems, the present invention is implemented through the following technical solution: A groove turning machine for producing motorcycle pulleys, comprising: The machine body, and a cooler fixedly installed on the top of the machine body, with a clamping mechanism installed on the side inside the machine body; The machining mechanism includes a linear driver and a pusher / puller. The linear driver is fixedly installed on the side of the inner wall of the machine body. The pusher / puller is fixedly installed on the output end of the linear driver. An I-shaped connecting block is fixedly installed on the output end of the pusher / puller. A rotary tool changer is installed on the top of the I-shaped connecting block. A push plate is fixedly installed on the side of the bottom of the pusher / puller. A turning assembly is installed on the output end of the rotary tool changer. By moving the output end of the linear driver, the pusher / puller can be moved. With the connection of the rotary tool changer, the turning assembly is moved as a whole. The position of the turning assembly is adjusted to facilitate turning the motorcycle pulley grooves at different positions. At the same time, the output end of the pusher / puller applies a pushing force to the I-shaped connecting block. With the connection of the I-shaped connecting block, the pusher / puller moves the turning assembly closer to the motorcycle pulley, thereby feeding the tool and controlling the turning depth of the motorcycle pulley. The rotary tool changer is pulled by the output end of the push-pull device, and the rotary tool changer and the turning assembly move together away from the motorcycle pulley by the sliding of the I-shaped connecting block, thus realizing the tool retraction. The turning assembly includes a polygonal cutter head and a hook-shaped tool holder. The center of the polygonal cutter head surface is fixedly installed to the output end of a rotary tool changer. The hook-shaped tool holder is detachably fixedly installed on the side of the polygonal cutter head surface. A fan is fixedly installed on the surface of the polygonal cutter head near the hook-shaped tool holder. An insert is detachably fixedly installed on the hook-shaped end of the hook-shaped tool holder surface. An air passage is opened inside the hook-shaped tool holder. A bent pipe is installed between the air outlet on the surface of the fan and the surface of the hook-shaped tool holder. By controlling the rotary tool changer through the output end of the push-pull device, the hook-shaped tool holder and the insert are brought closer to the surface of the motorcycle pulley to be turned. The insert can then contact the surface of the motorcycle pulley to turn the motorcycle pulley. The output end of the rotary tool changer drives the polygonal cutter head to rotate, which allows for tool replacement and facilitates continuous turning of the motorcycle pulley. An auxiliary mechanism is installed at the bottom of the internal cavity of the machine.

[0006] Furthermore, the clamping mechanism is used to fix and install the motorcycle pulley that needs to be turned, and to drive the pulley to rotate. The clamping mechanism includes a power source, which is fixedly installed inside the machine body. A three-jaw chuck is fixedly installed at the output end of the power source. A support turntable is fixedly clamped at the jaws on the surface of the three-jaw chuck. A positioner is installed on the surface of the support turntable near the blade. The positioner includes a support screw, one end of which is threadedly fixed to the side of the support turntable. A limit ring is fixedly connected to the surface of the support screw near the support turntable. A support cylinder is detachably fixed to the surface of the support screw via threads. A locking element is threaded to the end of the support screw away from the support turntable. A conical elastic bucket is fixedly installed on the surface of the locking element near the support cylinder. A rectangular notch is provided on the conical surface of the conical elastic bucket. By using the threaded connection between the support cylinder and the support screw, and fitting the weight reduction hole of the motorcycle pulley surface to be machined onto the surface of the support cylinder, the motorcycle pulley can be initially limited. The locking element is then tightened. The motorcycle pulley is positioned by the surface of the locking element fitting against the area around the weight reduction hole of the motorcycle pulley, thus fixing the motorcycle pulley and preventing loosening. Adjust the angle of the cooler's bottom outlet pipe so that the cooler's bottom outlet is aligned with the position to be machined on the motorcycle pulley surface. By rotating the power source output end, the three-jaw chuck can be driven to rotate, and under the support of the support turntable, the positioner is driven to rotate, thereby causing the motorcycle pulley on the positioner to rotate as well, which helps in the subsequent machining of the motorcycle pulley.

[0007] Furthermore, the support turntable and the three-jaw chuck are installed at the same height, and the support screws are evenly distributed on the sides of the support turntable surface.

[0008] Furthermore, the end of the support cylinder away from the limiting ring is provided with a conical concave surface, the surface of the conical elastic bucket is in contact with the inner side of the conical concave surface, and the rectangular notches are evenly distributed on the conical surface on the outer side of the conical elastic bucket.

[0009] When the locking parts are tightened, the conical surface of the conical elastic bucket fits into the conical concave surface at the end of the support cylinder. Through action and reaction forces, the conical elastic bucket is embedded into the concave surface and undergoes elastic deformation. The rectangular notches are evenly distributed on the conical surface of the conical elastic bucket, which helps the conical elastic bucket to undergo elastic deformation. Combined with action and reaction forces, the conical elastic bucket applies an elastic pushing force to the support cylinder, making it less prone to thread slippage in the support cylinder and resulting in a more secure connection between the structures. Furthermore, the support cylinder, locking components, and support screw are all detachably threaded, making it easy to replace the support cylinder with different diameters, which helps to adapt to the weight reduction holes of motorcycle pulleys with different inner diameters.

[0010] Furthermore, the liquid outlet at the bottom of the cooler penetrates through the top of the machine body and extends into its interior. The linear actuator is horizontally mounted, and there are two linear actuators, which are symmetrically mounted along the push-pull mechanism.

[0011] When the cutting tool is used to machine a motorcycle pulley, a chip breaker is installed at the tip of the cutting tool. This allows the freshly cut chip to come into contact with the tip, and the combined force of the chip breaker and the chip breaking block pushes the chip in the opposite direction, causing the chip to break. This prevents chip from getting tangled and avoids scratching the groove of the motorcycle pulley.

[0012] Furthermore, the air outlet of the air passage is located on the surface of the hook-shaped handle and close to the blade, and the hook-shaped handle is evenly distributed on the side of the polygonal blade disc surface.

[0013] By utilizing the blowing power of a blower and connecting it through a bend pipe, the air blown by the blower enters the air passage through the bend pipe. This allows the airflow to blow out from the air outlet of the air passage onto the surface of the cutting tool, blowing away the debris attached to the surface of the cutting tool and preventing debris accumulation, which helps the cutting tool to perform accurate turning.

[0014] Furthermore, the blowers are evenly distributed on the surface of the polygonal cutter head, and the bent pipe connects the blowers to the air duct.

[0015] Furthermore, the auxiliary mechanism includes a square guide post and a water receiving trough. The bottom end of the square guide post is fixedly installed to the bottom of the inner cavity of the machine body. The water receiving trough is slidably installed on the surface of the square guide post. A circular roller is rotatably installed on the inner wall of the water receiving trough near the top. A roller is fixedly installed on one end of the circular roller extending to the outside of the water receiving trough. An elastic brush is fixedly installed on the outer circular surface of the circular roller.

[0016] By rolling the elastic brush, the surface of the motorcycle pulley comes into contact with the brush, which not only brushes the coolant onto the surface of the pulley, forming a liquid film of coolant on one side of the pulley, thus lubricating and cooling it during subsequent turning, but also removes the debris adhering to the surface of the pulley by brushing the elastic brush, which helps to make the turning more accurate and prevents debris from getting stuck between the cutting tool and the groove of the pulley.

[0017] Furthermore, the square guide pillars are installed vertically, and there are two square guide pillars, which are symmetrically installed along the water receiving groove, which is installed directly below the cooler outlet.

[0018] Furthermore, the rollers are installed horizontally, and there are two rollers, which are symmetrically installed along the central axis of the water receiving trough. The elastic brushes are evenly distributed on the outer surface of the rollers.

[0019] The beneficial effects of the technical solution provided by this invention include: 1. By moving the output end of the linear drive, the push-pull device can be moved. With the connection of the rotary tool changer, the entire turning assembly is moved, and the position of the entire turning assembly is adjusted to facilitate turning the motorcycle pulley grooves at different locations. At the same time, the output end of the push-pull device applies a pushing force to the I-shaped connecting block, and with the connection of the I-shaped connecting block, the push-pull device moves the entire turning assembly closer to the motorcycle pulley, thereby feeding the tool and controlling the turning depth of the motorcycle pulley.

[0020] Second, by controlling the rotary tool changer through the output end of the push-pull device, the hook-shaped tool holder and the insert are brought closer to the surface of the motorcycle pulley to be machined. The insert can then contact the surface of the motorcycle pulley to machine it. The output end of the rotary tool changer drives the polygonal cutter head to rotate, which allows for tool replacement and facilitates continuous machining of the motorcycle pulley.

[0021] Third, when the cutting tool is used to machine the motorcycle pulley, the chip breaker is installed at the tip of the cutting tool. This allows the freshly cut wire chip to come into contact with the tip. Combined with the force of the cutting tool, the wire chip is pushed in the opposite direction by the chip breaker, which breaks the wire chip and prevents the chip from getting tangled. This avoids scratching the groove of the motorcycle pulley being machined.

[0022] Fourth, by utilizing the blowing force of the blower and connecting it with the bend pipe, the air blown by the blower enters the air passage through the bend pipe. This allows the airflow to blow out from the air outlet of the air passage onto the surface of the cutting tool, blowing away the debris attached to the surface of the cutting tool and preventing the accumulation of debris, which helps the cutting tool to perform accurate turning.

[0023] 5. By using the threaded installation between the support cylinder and the support screw, and fitting the weight reduction hole on the surface of the motorcycle pulley that needs to be machined onto the surface of the support cylinder, the motorcycle pulley can be initially limited. The locking parts are then tightened. By the surface of the locking parts fitting against the area around the weight reduction hole of the motorcycle pulley, the motorcycle pulley is positioned and fixed to prevent loosening.

[0024] VI. Through action and reaction forces, the conical elastic bucket undergoes elastic deformation after being embedded in the conical concave surface. The rectangular notches are evenly distributed on the conical surface of the conical elastic bucket, which helps the conical elastic bucket to undergo elastic deformation. Combined with action and reaction forces, the conical elastic bucket applies an elastic pushing force to the support cylinder, making it less prone to thread slippage in the support cylinder and resulting in a more robust connection between structures.

[0025] 7. By rolling the elastic brush, the elastic brush contacts the surface of the motorcycle pulley, which not only brushes the coolant onto the surface of the motorcycle pulley, forming a liquid film of coolant on one side of the motorcycle pulley, thus lubricating and cooling it during subsequent turning, but also removes the debris adhering to the surface of the motorcycle pulley by brushing the elastic brush, which helps to turn accurately and prevents debris from getting stuck between the cutting tool and the turning pulley groove.

[0028] Example 1, see Figures 1-4 A technical solution is provided: A groove turning machine for producing motorcycle pulleys, comprising: The machine body 1, and the cooler 2 fixedly installed on the top of the machine body 1. The liquid outlet at the bottom of the cooler 2 penetrates the top of the machine body 1 and extends into its interior. A clamping mechanism 3 is installed on the side inside the machine body 1. Machining mechanism 4 includes a linear driver 41 and a pusher 42. The linear driver 41 is fixedly installed on the side of the inner wall of the machine body 1. The pusher 42 is fixedly installed on the output end of the linear driver 41. An I-shaped connecting block 43 is fixedly installed on the output end of the pusher 42. A rotary tool changer 44 is installed on the top of the I-shaped connecting block 43. A push plate 45 is fixedly installed on the side of the bottom of the pusher 42. A turning assembly 46 is installed on the output end of the rotary tool changer 44. When the linear driver 41 is turned on, the push-pull device 42 is moved by the movement of the output end of the linear driver 41. With the connection of the rotary tool changer 44, the turning assembly 46 is moved as a whole, and the position of the turning assembly 46 is adjusted to facilitate turning the motorcycle pulley groove at different positions. At the same time, the output end of the push-pull device 42 applies a pushing force to the I-shaped connecting block 43. With the connection of the I-shaped connecting block 43, the push-pull device 42 moves the turning assembly 46 closer to the motorcycle pulley, thereby feeding the tool and controlling the turning depth of the motorcycle pulley. The output end of the push-pull device 42 applies a pulling force to the rotary tool changer 44, and the sliding of the I-shaped connecting block 43 causes the rotary tool changer 44 and the turning assembly 46 to move together away from the motorcycle pulley, thereby realizing tool retraction. The linear actuator 41 is mounted horizontally. There are two linear actuators 41, and the two linear actuators 41 are mounted symmetrically along the push-pull mechanism 42. The turning assembly 46 includes a polygonal cutter head 461 and a hook-shaped tool holder 462. The center of the polygonal cutter head 461 is fixedly installed to the output end of a rotary tool changer 44. The hook-shaped tool holder 462 is detachably fixedly installed on the side of the polygonal cutter head 461. A blower 463 is fixedly installed on the surface of the polygonal cutter head 461 near the hook-shaped tool holder 462. A cutting insert 464 is detachably fixedly installed on the hook-shaped end of the cutting insert 462. An air passage 465 is opened inside the hook-shaped tool holder 462. A bent pipe 466 is installed between the air outlet on the surface of the blower 463 and the surface of the hook-shaped tool holder 462. A pointed tip is fixedly connected to the surface of the cutting insert 464. The chip breaker 467 controls the rotary tool changer 44 via the output end of the push-pull device 42. With the connection of the polygonal cutter head 461, the hook-shaped tool holder 462 and the insert 464 move closer to the surface of the motorcycle pulley to be machined. The insert 464 can then contact the surface of the motorcycle pulley to machine it. The push-pull device 42 applies a pulling force to the I-shaped connecting block 43, causing the hook-shaped tool holder 462 to move away from the motorcycle pulley. The output end of the rotary tool changer 44 drives the polygonal cutter head 461 to rotate, allowing tool changes and facilitating continuous machining of the motorcycle pulley. The air outlet of the air passage 465 is located on the surface of the hook-shaped tool holder 462 and close to the blade 464. The hook-shaped tool holder 462 is evenly distributed on the side of the polygonal cutter head 461. When the blade 464 is turning the motorcycle pulley, the chip breaker 467 is installed at the tip of the blade 464. This allows the freshly cut wire scrap to come into contact with the tip. Combined with the combined force and the force of the cutting, the wire scrap is pushed in the opposite direction by the chip breaker 467, which breaks the wire scrap. This prevents the scrap from getting tangled and avoids scratching the groove of the turned motorcycle pulley.

[0029] The blowers 463 are evenly distributed on the surface of the polygonal cutter head 461. The bent pipe 466 connects the blowers 463 and the air passage 465. When the blowers 463 are turned on, the air blown out by the blowers 463 and connected by the bent pipe 466 is transported into the air passage 465 through the bent pipe 466. This allows the airflow to blow out from the air outlet of the air passage 465 onto the surface of the cutting tool 464, blowing away the debris attached to the surface of the cutting tool 464 and preventing debris accumulation, which helps the cutting tool 464 to perform accurate turning.

[0030] Example 2, based on Example 1, see [link / reference] Figures 1 to 7 A technical solution is provided: The clamping mechanism 3 is used to fix and install the motorcycle pulley that needs to be turned, and to drive the pulley to rotate. The clamping mechanism 3 includes a power source 31, which is fixedly installed inside the machine body 1. A three-jaw chuck 32 is fixedly installed at the output end of the power source 31. A support turntable 33 is fixedly clamped at the jaws on the surface of the three-jaw chuck 32. A positioner is installed on the surface of the support turntable 33 near the blade 464. The positioner includes a support screw 34. One end of the support screw 34 is threadedly fixed to the side of the support turntable 33. A limit ring 35 is fixedly connected to the surface of the support screw 34 near the support turntable 33. A support cylinder 36 is detachably fixed to the surface of the support screw 34 via threads. A locking element 37 is threadedly installed at the end of the support screw 34 away from the support turntable 33. A conical elastic bucket 38 is fixedly installed on the surface of the locking element 37 near the support cylinder 36. A rectangular notch 39 is formed on the conical surface of the conical elastic bucket 38. The support turntable 33 is fixed by applying clamping force to the jaws on the surface of the three-jaw chuck 32. The support turntable 33 can be fixed by applying tightening force to the hexagonal nut at the end of the support screw 34. The support screw 34 is fixedly installed on the surface of the support turntable 33 by the thread between the support cylinder 36 and the support screw 34. The weight-reducing holes on the surface of the motorcycle pulley to be machined are fitted onto the surface of the support cylinder 36, which initially limits the movement of the motorcycle pulley. The locking part 37 is then threaded onto the support screw 34 and tightened. The surface of the locking part 37 fits against the area around the weight-reducing holes of the motorcycle pulley, thus positioning the motorcycle pulley. This fixation prevents the motorcycle pulley from loosening. The angle of the liquid outlet pipe at the bottom of the cooler 2 is adjusted so that the liquid outlet at the bottom of the cooler 2 is aligned with the position on the surface of the motorcycle pulley to be machined. The power source 31 is then turned on. The rotation of the output end of the power source 31 drives the three-jaw chuck 32 to rotate. With the support of the support turntable 33, the positioner is driven to rotate, causing the motorcycle pulley on the positioner to rotate as well, which facilitates the subsequent machining of the motorcycle pulley.

[0031] The support turntable 33 and the three-jaw chuck 32 are installed at the same height. The support screw 34 is evenly distributed on the side of the support turntable 33. When the locking part 37 is tightened, the conical surface of the conical elastic bucket 38 fits with the conical concave surface at the end of the support cylinder 36. Through action and reaction forces, the conical elastic bucket 38 is embedded in the concave surface and undergoes elastic deformation. The rectangular notches 39 are evenly distributed on the conical surface of the conical elastic bucket 38, which helps the conical elastic bucket 38 to undergo elastic deformation. Combined with action and reaction forces, the conical elastic bucket 38 applies an elastic pushing force to the support cylinder 36. The support cylinder 36 is less prone to thread slippage, and the connection between the structures is more secure. The support cylinder 36, the locking part 37 and the support screw 34 are all threaded and detachable, which makes it easy to replace the support cylinder 36 with different diameters and helps to adapt to the weight reduction holes of motorcycle pulleys with different inner diameters.

[0032] Example 3, based on Examples 1 and 2, see below. Figures 1 to 8 A technical solution is provided: The auxiliary mechanism 5 includes a square guide post 51 and a water receiving trough 52. The bottom end of the square guide post 51 is fixedly installed to the bottom of the inner cavity of the machine body 1. The water receiving trough 52 is slidably installed on the surface of the square guide post 51. A circular roller 53 is rotatably installed on the inner wall of the water receiving trough 52 near the top. A roller 54 is fixedly installed on one end of the circular roller 53 extending to the outside of the water receiving trough 52. An elastic brush 55 is fixedly installed on the outer circular surface of the circular roller 53. The roller 53 is moved towards the side of the motorcycle pulley by the pusher 42 in preparation for turning. The pusher 42 will drive the push plate 45 to move together. The push plate 45 will apply an upward pushing force to the water receiving trough 52 by using the inclined surface of the push plate 45 to fit against the side of the bottom of the water receiving trough 52. Under the guidance of the square guide post 51, the water receiving trough 52 moves upward, and the circular roller 53 and roller 54 will move upward together with the water receiving trough 52. The outer circular surface of the roller 54 and the roller 54 will apply an upward pushing force to the water receiving trough 52 by using the roller 54 to fit against the side of the bottom of the water receiving trough 52. The outer surface of the three-jaw chuck 32 is engaged, and the rotation of the three-jaw chuck 32 causes the roller 54 to drive the circular roller 53 to roll together, which allows the elastic brush 55 to rotate in a circle. When the coolant outlet of the cooler 2 cools the turning process, the coolant flows downward and collects inside the water receiving tank 52. As the circular roller 53 drives the elastic brush 55 to roll, the elastic brush 55 contacts the surface of the motorcycle pulley. This not only brushes the coolant onto the surface of the motorcycle pulley, forming a liquid film of coolant on one side of the motorcycle pulley, which lubricates and cools it during subsequent turning, but also removes the debris adhering to the surface of the motorcycle pulley by brushing the elastic brush 55, which helps to turn accurately and prevents debris from getting stuck between the cutting tool 464 and the turning pulley groove.

[0033] Two square guide pillars 51 are installed vertically and are installed symmetrically along the water receiving trough 52. The water receiving trough 52 is installed directly below the outlet of the cooler 2.

[0034] Two circular rollers 53 are installed horizontally, and the two circular rollers 53 are symmetrically installed along the central axis of the water receiving trough 52. Elastic brushes 55 are evenly distributed on the outer surface of the circular rollers 53.

[0035] When using it, first adjust the angle of the liquid outlet pipe at the bottom of the cooler 2 so that the liquid outlet pipe at the bottom of the cooler 2 is aligned with the position to be machined. At this point, the jaws on the surface of the three-jaw chuck 32 apply clamping force to the support turntable 33, thus fixing the support turntable 33. Tightening force is applied to the hexagonal nut at the end of the support screw 34, fixing the support screw 34 onto the surface of the support turntable 33. The support cylinder 36 is threaded onto the support screw 34, and the weight-reducing hole on the surface of the motorcycle pulley to be machined is fitted onto the surface of the support cylinder 36, thus initially limiting the movement of the motorcycle pulley. The locking member 37 is then threaded onto the support screw 34 and tightened. The surface of the fastener 37 fits against the area around the weight reduction hole of the motorcycle pulley, thereby positioning the motorcycle pulley. The motorcycle pulley is fixed to prevent loosening. The angle of the liquid outlet pipe at the bottom of the cooler 2 is adjusted so that the liquid outlet at the bottom of the cooler 2 is aligned with the position to be machined on the surface of the motorcycle pulley. The power source 31 is turned on to start working. The rotation of the output end of the power source 31 can drive the three-jaw chuck 32 to rotate. Under the support of the support turntable 33, the positioner is driven to rotate, thereby causing the motorcycle pulley on the positioner to rotate together. The operator starts the linear drive 41 and moves it. The pusher 42 is moved by the movement of the output end of the linear drive 41. With the connection of the rotary tool changer 44, the turning assembly 46 is moved as a whole. The position of the turning assembly 46 is adjusted to facilitate turning of the motorcycle pulley groove at different positions. At the same time, the output end of the pusher 42 applies a pushing force to the I-shaped connecting block 43. With the connection of the I-shaped connecting block 43, the pusher 42 moves the turning assembly 46 closer to the motorcycle pulley, thus feeding the tool. Simultaneously, the output end of the push-pull device 42 controls the rotary tool changer 44, and with the connection of the polygonal tool disc 461, the hook-shaped tool holder 462 and the insert 464 move closer to the surface of the motorcycle pulley that needs to be machined. The insert 464 can then contact the surface of the motorcycle pulley to machine it. The output end of the push-pull device 42 applies a pulling force to the I-shaped connecting block 43, causing the hook-shaped tool holder 462 to move away from the motorcycle pulley. The output end of the rotary tool changer 44 drives the polygonal tool disc 461 to rotate, allowing for tool replacement. Furthermore, the pusher 42 moves towards the side closer to the motorcycle pulley in preparation for turning. The pusher 42 will drive the push plate 45 to move together. Utilizing the inclined surface of the push plate 45 to fit against the bottom edge of the water receiving trough 52, the push plate 45 will apply an upward pushing force to the water receiving trough 52. Guided by the square guide post 51, the water receiving trough 52 moves upward, and the circular roller 53 and roller 54 move upward together with the water receiving trough 52. Utilizing the outer circular surface of the roller 54 to fit against the outer circular surface of the three-jaw chuck 32, and through the rotation of the three-jaw chuck 32, the roller 54 drives the circular roller 53 to roll together, thus allowing the elastic brush 55 to rotate circumferentially, and the cooler 2 to... When the coolant is cooled by the water outlet, it flows downward and collects inside the water tank 52. As the roller 53 drives the elastic brush 55 to roll, the elastic brush 55 contacts the surface of the motorcycle pulley. This not only brushes the coolant onto the surface of the motorcycle pulley, forming a liquid film of coolant on one side of the surface, which lubricates and cools the pulley during subsequent turning, but also removes the debris adhering to the surface of the motorcycle pulley by brushing the elastic brush 55. This helps to make the turning accurate and prevents debris from getting stuck between the cutting tool 464 and the groove of the pulley being turned. After the motorcycle pulley groove is machined, the cooler 2 is paused, and the machining assembly 46 is moved outward and reset through the linkage of the push-pull device 42 and the linear drive 41. The locking part 37 is then unscrewed, and the motorcycle pulley with the machined surface of the support cylinder 36 can be removed.

[0036] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
