Description

Technical Field

[0001] The invention relates to the technical field of polishing and grinding, in particular to a polishing machine for mechanical processing with adjustable angle. Background Art

[0002] Polishing machines are essential equipment in modern industrial manufacturing, playing a crucial role in surface treatment processes. By combining advanced technology with efficient operation, polishing machines can grind and polish workpieces of various materials, achieving a smooth, shiny finish.

[0003] In the prior art, when polishing a conical workpiece with a cylindrical rear end, the equipment can only polish the conical surface of the cone, and when polishing the cylindrical rear end of the workpiece, it is necessary to manually adjust the polishing angle. Moreover, when polishing the workpiece, due to the particularity of the conical workpiece, the polishing of its inclined surface requires very high precision. The overheating generated during polishing may damage the surface of the workpiece. At the same time, when cleaning the used cooling liquid, the equipment cannot centrally and automatically collect and clean the used liquid. In order to solve the above problems, a polishing machine with adjustable angle for mechanical processing is provided. Summary of the Invention

[0004] The present invention aims to solve the technical problem of how to automatically adjust the polishing angle when polishing a conical workpiece, cool the workpiece during polishing, improve the polishing accuracy, and the equipment can also centrally collect the cooling liquid for easy recycling. A polishing machine with adjustable angle is provided for mechanical processing.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] An angle-adjustable polishing machine for mechanical processing comprises a polishing device, a polishing cooling device, a cleaning device, a housing, and a controller.

[0007] The housing is mounted on the ground via a support frame. A polishing device is mounted on and connected to the housing. A polishing and cooling device is mounted on and connected to the housing and is in driving connection with the polishing device. A cleaning device is mounted within the housing and is connected to the housing and is in driving connection with the polishing device. A controller is mounted on the side of the housing and fixedly connected to the front of the housing. The controller is electrically connected to the polishing device and the polishing and cooling device.

[0008] When the user wants to polish a conical workpiece, the user can first place the workpiece inside the shell, and then start the polishing device through the controller. After the polishing device is started, the polishing device can carefully grind the conical inclined surface of the workpiece, so as to achieve the function of uniformly grinding each area of the inclined surface of the conical workpiece. At the same time, when the polishing device is grinding the workpiece, the polishing device can also drive the polishing cooling device to start, so as to spray liquid onto the surface of the workpiece and the polishing device, so that the polishing cooling device can be started only when the polishing device is polishing the workpiece, reduce the temperature of the polishing area, and assist in polishing the workpiece, thereby improving the polishing accuracy of the workpiece. The polishing device can also drive the cleaning device to operate, and the cleaning device can collect and clean the liquid remaining on the bottom surface of the shell, so that the liquid with workpiece debris can be collected and wait for recycling, thereby improving the economic benefits of the equipment and protecting the cleanliness of the processing area.

[0009] This function achieves the following technical effects: when polishing a conical workpiece, the equipment can automatically adjust the polishing angle and cool the workpiece during polishing to improve the polishing accuracy. The equipment can also collect the cooling liquid for easy recycling.

[0010] Furthermore, the polishing device includes: a rotating telescopic motor, a connecting disc, three polishing blocks, a horizontal slide groove, a vertical slide groove, a horizontal connecting spring, and a vertical connecting spring.

[0011] The rotary telescopic motor is arranged on the outer side of the shell, the shell of the rotary telescopic motor is fixedly connected to the outer side of the shell through a support block, and the telescopic shaft of the rotary telescopic motor passes through the side wall of the shell and extends to the inside of the shell. The telescopic shaft of the rotary telescopic motor is rotatably connected to the side wall of the shell, and the rotation axis is arranged horizontally.

[0012] The connecting disc is arranged inside the shell, on the side of the telescopic rod of the rotary telescopic motor. The side surface of the connecting disc is fixedly connected to one end surface of the telescopic rod extending from the rotary telescopic motor to the inside of the shell, and the other side surface is connected to the planar end surface of the conical workpiece.

[0013] The transverse slide is arranged inside the shell, on the side of the connecting disc away from the rotating and telescopic motor. The transverse slide is arranged on the inner wall of the shell opposite to the side where the connecting disc is connected to the conical workpiece. The length of the transverse slide is consistent with the length of the inner wall of the shell. The transverse slide is also connected to the cleaning device.

[0014] The vertical slide is arranged inside the shell, just above the middle of the horizontal slide. The vertical slide is arranged on the inner wall of the shell where the horizontal slide is arranged, and is perpendicular to the arrangement direction of the horizontal slide.

[0015] The three grinding blocks are horizontally arranged inside the shell and are respectively located on the side of the connecting disc away from the rotating and telescopic motor. One end faces of two of the three grinding blocks, grinding block A and grinding block B, are respectively arranged inside the horizontal slide groove, and are respectively slidably connected to the inner wall of the horizontal slide groove, and are respectively connected to the cleaning device. There is a gap between the grinding block A and the grinding block B, and one end face of the grinding block C among the three grinding blocks is arranged inside the vertical slide groove, and is slidably connected to the inner wall of the vertical slide groove, and is connected to the polishing and cooling device. The end faces of the three grinding blocks close to the connecting disc are respectively set as inclined grinding surfaces, and the inclination angle of the inclined grinding surface matches the surface inclination angle of the conical end face of the conical workpiece.

[0016] The transverse connecting spring is arranged inside the shell, between the A grinding block and the B grinding block. The transverse connecting spring is arranged inside the transverse slide groove, and the two ends are respectively fixedly connected to the side surfaces of the A grinding block and the B grinding block close to each other.

[0017] The vertical connecting spring is arranged inside the shell, below the C grinding block. The vertical connecting spring is arranged inside the vertical slide groove, and the bottom end is fixedly connected to the inner bottom end surface of the vertical slide groove, and the top end is fixedly connected to the side of the C grinding block close to the other two grinding blocks.

[0018] When the user wants to polish a conical workpiece, the user first places the flat surface of the workpiece on the connecting disc so that the connecting disc fixes the workpiece, and then the user starts the rotary telescopic motor forward and extends through the controller. After the rotary telescopic motor is started forward and extends, the rotary telescopic shaft can rotate and extend. The rotary telescopic shaft can rotate and extend to drive the connecting disc to rotate and move toward the direction close to the three grinding blocks. The rotation and movement of the connecting disc drive the workpiece to rotate and move until the conical inclined surface of the workpiece gradually contacts the inclined grinding surfaces of the three grinding blocks. When the inclined grinding surfaces of the three grinding blocks contact the conical inclined surface of the workpiece, the three grinding blocks will grind and polish the conical surface of the workpiece. At the same time, the movement of the workpiece will continuously squeeze the three grinding blocks.

[0019] When the workpiece squeezes the three grinding blocks, grinding block A and grinding block B are squeezed and move away from each other along the horizontal slide groove, and drive the cleaning device to move respectively. Grinding block A and grinding block B are squeezed and move along the horizontal slide groove, which will exert tension on the horizontal connecting spring. After receiving the pressure, the horizontal connecting spring will extend, thereby expanding the distance between grinding block A and grinding block B.

[0020] When pressed, grinding block C moves upward along the vertical chute. This upward movement drives the vertical connecting rod upward, applying tension to the vertical connecting spring, causing it to extend. As grinding blocks A, B, and C move, the spacing between them increases, adjusting the height of the inclined grinding surfaces of the three grinding blocks to match the different areas of the workpiece's conical surface. This continues until the workpiece fully fits within the spacing between the three grinding blocks, at which point the grinding surfaces of the three grinding blocks begin grinding the cylindrical rear end of the workpiece.

[0021] When the user wants to take out the workpiece, the user can control the rotary telescopic motor to reverse and retract through the controller. After the rotary telescopic motor is reversed and retracted, the rotary telescopic shaft can rotate and retract. The rotation and retraction of the rotary telescopic shaft drive the connecting disc to rotate and move in the direction away from the three grinding blocks. The rotation and movement of the connecting disc drive the workpiece to rotate and move until the workpiece can leave the space formed between the three grinding blocks. When the three grinding blocks rotate to leave the space formed between the three grinding blocks, the three grinding blocks will still grind the cylindrical rear end of the workpiece. At the same time, the inclined grinding surfaces of the three grinding blocks will still grind and polish the conical surface of the workpiece. At the same time, the cylindrical rear end of the workpiece will gradually reduce the pressure applied to the three grinding blocks when leaving the flat grinding surfaces of the three grinding blocks until the workpiece completely leaves the three grinding blocks.

[0022] As the workpiece gradually reduces the pressure on the three grinding blocks, the reduced pressure on grinding blocks A and B reduces the pressure on the horizontal connecting spring. The horizontal connecting spring gradually shortens and drives grinding blocks A and B closer together. The approach of grinding blocks A and B drives the cleaning device to move. The reduced pressure on grinding block C reduces the pressure on the vertical connecting spring. The vertical connecting spring extends and the pressure is reduced, driving grinding block C downward. The downward movement of grinding block C drives the polishing and cooling device downward. As grinding blocks A, B, and C move closer to each other, the distance between them decreases, thereby adjusting the height of the inclined grinding surfaces of the three grinding blocks until they return to their original position, thereby matching the conical surface of the workpiece again. The conical surface of the workpiece is then polished until the workpiece completely leaves the inclined grinding surfaces of the three grinding blocks. The workpiece is then collected.

[0023] Furthermore, the sides of the three grinding blocks that are close to each other are respectively set as grinding surfaces, the mesh counts of the grinding surfaces are consistent, and the lengths of the three grinding blocks are greater than the length of the conical workpiece.

[0024] The lengths of the three grinding blocks being greater than the length of the workpiece can prevent the conical top of the workpiece from contacting the inner wall of the shell, thereby damaging the workpiece.

[0025] Furthermore, the connecting disc is configured as an electromagnetic suction cup and is electrically connected to the controller.

[0026] Setting the connecting disc as an electromagnetic chuck can effectively fix the planes of conical workpieces of different sizes.

[0027] Furthermore, the polishing and cooling device includes: a right-angle tube, a liquid storage tank, a spray pipe, a plurality of spray heads, a plurality of liquid leakage holes, a water valve, a vertical connecting rod, and a handle groove.

[0028] The liquid storage box is arranged above the shell, and the outer bottom surface of the liquid storage box is fixedly connected to the top surface of the shell.

[0029] The right-angle tube is arranged inside the shell, above the C grinding block. One end of the vertical tube of the right-angle tube passes through the top of the shell and the bottom of the liquid storage box and is connected to the interior of the liquid storage box. The horizontal tube of the right-angle tube is parallel to the inner bottom surface of the shell.

[0030] The water valve is arranged inside the shell and between the right-angle tube and the connecting disc. One end of the water valve is communicated with the transverse tube port of the right-angle tube.

[0031] The spray pipe is arranged inside the shell, between the right-angle pipe and the connecting disc, above the C grinding block, one end of the spray pipe is connected to the other end of the water valve, and the other end is closed.

[0032] The plurality of spray heads are respectively arranged inside the shell and between the spray pipe and the C grinding block. The input ports of the plurality of spray heads respectively pass through the side of the spray pipe and are communicated with the interior of the spray pipe.

[0033] The vertical connecting rod is arranged inside the shell, on the side of the water valve and above the C grinding block, and the bottom end of the vertical connecting rod is fixedly connected to the top surface of the C grinding block.

[0034] The handle slot is arranged at the handle end of the vertical connecting rod close to the water valve. The handle slot is a through hole slot, and the handle of the water valve passes through the handle slot.

[0035] A plurality of liquid leakage through holes are respectively arranged on the side of the C grinding block, and the ports correspond to the spraying directions of the plurality of spray heads.

[0036] When the C grinding block is squeezed and moves upward along the vertical slide, the upward movement of the C grinding block drives the vertical connecting rod to move upward. The upward movement of the vertical connecting rod pushes the handle of the water valve to rotate upward through the handle slot. The upward rotation of the water valve handle will open the internal switch of the water valve. After the internal switch of the water valve is turned on, the liquid inside the liquid storage tank will pass through the right-angle pipe and the water valve into the spray pipe, and then pass through several spray heads to be sprayed onto the surface of the workpiece and the surface of the C grinding block. When the liquid falls on the surface of the C grinding block, it will pass through several leakage holes into the surface of the workpiece below the C grinding block, so as to reduce the temperature of the three grinding blocks when polishing the workpiece surface.

[0037] When the C grinding block is squeezed and moves downward along the vertical slide groove, the downward movement of the C grinding block drives the vertical connecting rod to move downward. The downward movement of the vertical connecting rod pushes the handle of the water valve to rotate downward through the handle groove. The downward rotation of the water valve handle will gradually close the internal switch of the water valve until the internal switch of the water valve is completely closed. The liquid inside the liquid storage tank will stop passing through the right-angle pipe and the water valve into the spray pipe, thereby stopping the injection of liquid into several spray heads and avoiding liquid waste.

[0038] Furthermore, the liquid in the liquid storage box is polishing liquid.

[0039] Setting the liquid inside the liquid storage tank as polishing liquid can not only reduce the temperature of the workpiece during polishing, but also assist in the polishing of the workpiece.

[0040] Furthermore, several of the spray heads are swing-type spray heads.

[0041] Several spray heads are oscillating spray heads that can effectively and evenly spray the polishing liquid onto the surface of the workpiece.

[0042] Furthermore, the polishing and cooling device further comprises: a stirring device. The stirring device is arranged inside the liquid storage box, connected to the inner wall of the liquid storage box, and electrically connected to the controller.

[0043] By setting a stirring device inside the polishing and cooling device, the user can start the stirring device to ensure that the polishing liquid is always in the best working condition, avoiding the precipitation of the polishing liquid and causing its working performance to deteriorate.

[0044] Furthermore, the cleaning device includes: two push rods, two return springs, two cleaning rods, three liquid leakage ports, and two sliding blocks.

[0045] The two push rods are respectively arranged horizontally inside the horizontal slide groove and are respectively located on the sides of the A grinding block and the B grinding block. One end of the two push rods is respectively fixedly connected to the side of the A grinding block and the B grinding block away from the horizontal connecting spring.

[0046] The two sliding blocks are respectively arranged inside the transverse sliding groove, respectively located on the side of the other end of the two push rods, and respectively slidably connected to the inner wall of the transverse sliding groove, and the side surfaces of the two sliding blocks are respectively in contact with the other end surfaces of the two push rods.

[0047] The two return springs are respectively arranged horizontally inside the horizontal slide groove, and are respectively located on the sides of the two sliding blocks away from the two push rods. One end of the two return springs is fixedly connected to the inner wall end surface of the horizontal slide groove, and the other end is fixedly connected to the side of the two sliding blocks away from the two push rods.

[0048] The two cleaning rods are right-angle rods and are respectively arranged inside the shell, on the side of the A grinding block and the B grinding block away from the horizontal connecting spring. The vertical rod sides of the two cleaning rods are respectively fixedly connected to the side faces of the two sliding blocks, and the horizontal rods of the two cleaning rods are respectively located above the inner bottom surface of the shell and are respectively parallel to the inner bottom surface of the shell, and scrapers are respectively provided on the sides close to the inner bottom surface of the shell, and the scrapers are in contact with the inner bottom surface of the shell.

[0049] Three liquid leakage ports are respectively arranged at the bottom of the shell, and two of the liquid leakage ports are close to two opposite side walls of the shell, and the other liquid leakage port is directly below the C grinding block. The three liquid leakage ports are connected to the interior of the shell, and the setting direction is parallel to the setting direction of the three grinding blocks. Two of the three liquid leakage ports that are close to each other are respectively located on the left and right sides of one of the two cleaning rods.

[0050] When grinding block A and grinding block B are squeezed and move away from each other along the horizontal slide groove, grinding block A and grinding block B move in the direction away from each other, respectively driving the two push rods to move along the horizontal slide groove toward the direction close to the two sliding blocks. The movement of the two push rods will contact the side surfaces of the two sliding blocks and push the two sliding blocks to move toward the direction close to the two return springs. The movement of the two sliding blocks toward the direction close to the two return springs will apply pressure to the two return springs and drive the two cleaning rods to move. The two return springs will shorten after receiving the pressure and respectively drive the two sliding blocks to move again toward the direction close to the two return springs until the two return springs are completely shortened to the minimum length.

[0051] The movement of the two cleaning rods will drive the scrapers on the two cleaning rods to move. The movement of the scrapers can scrape the polishing liquid mixed with workpiece debris falling on the bottom surface of the inner wall of the shell into the two leakage ports close to the two side walls of the shell, and then leave the inside of the shell.

[0052] When grinding block A and grinding block B approach each other, they drive the two push rods to move along the horizontal sliding groove in the direction away from the two sliding blocks, and the two push rods stop moving to apply pressure to the two sliding blocks. After the two sliding blocks stop being under pressure, they will stop applying pressure to the two return springs. After the two return springs stop being under pressure, they will drive the two sliding blocks to move in the direction close to the two push rods until the two return springs are fully restored.

[0053] The movement of the two sliding blocks drives the two cleaning rods to move, and the movement of the two cleaning rods drives the scrapers on the two cleaning rods to move closer to each other. The movement of the scrapers can scrape the polishing liquid mixed with workpiece debris that falls on the bottom surface of the inner wall of the shell to the inside of the leakage port directly below the C grinding block and leave the inside of the shell.

[0054] Furthermore, the cleaning device further includes a sedimentation tank. The sedimentation tank is disposed below the housing, with the top surface fixedly connected to the bottom surface of the housing and connected to the interior of the housing through three leakage ports. The interior of the sedimentation tank is provided with an inclined plate, and the surface of the inclined plate is a stepped surface.

[0055] When the polishing liquid mixed with workpiece debris leaves the inside of the shell through the three leakage ports, it will fall into the sedimentation box, and then accelerate the sedimentation through the inclined plate inside the sedimentation box, so that the polishing liquid mixed with workpiece debris can be purified, making it convenient for users to collect reusable polishing liquid, thereby improving the utilization rate of the polishing liquid.

[0056] Beneficial effects of the present invention:

[0057] 1. The present invention provides a polishing device, a polishing and cooling device, a cleaning device, a housing, and a controller that cooperate and support each other. The polishing device can automatically adjust the angle while polishing the conical surface of the conical workpiece, thereby carefully and evenly polishing all positions of the inclined surface of the conical workpiece. The polishing and cooling device sprays polishing liquid on the surface of the polishing device and the workpiece when the polishing device is in operation, thereby assisting the polishing device in polishing the workpiece. The activation time of the polishing and cooling device is reasonably controlled to avoid waste of polishing liquid. The polishing device can also drive the cleaning device to operate, so that the cleaning device can centrally clean the polishing liquid that falls on the bottom surface of the housing and mixes with the debris generated during the polishing of the workpiece, thereby centrally collecting the used polishing liquid for subsequent recycling. This function achieves the technical effect that when polishing a conical workpiece, the device can automatically adjust the polishing angle and cool the workpiece during polishing to improve polishing accuracy.

[0062] The following will clearly and completely describe the concept and technical effects of the present invention in conjunction with the embodiments so as to fully understand the purpose, characteristics and effects of the present invention.

[0063] See also Figure 1-3 : A polishing machine for mechanical processing with adjustable angle, including: a polishing device, a polishing cooling device, a cleaning device, a shell 1, and a controller 5.

[0064] The housing 1 is mounted on the ground via a support frame. The polishing device is mounted on and connected to the housing 1. The polishing and cooling device is mounted on and connected to the housing 1 and is in driving connection with the polishing device. The cleaning device is mounted within the housing 1 and is in driving connection with the housing 1 and the polishing device. The controller 5 is mounted on the side of the housing 1 and is fixedly connected to the front of the housing 1. The controller 5 is electrically connected to the polishing device and the polishing and cooling device.

[0065] When the user wants to polish a conical workpiece, the user can first place the workpiece inside the shell 1, and then start the polishing device through the controller 5. After the polishing device is started, the polishing device can carefully grind the conical inclined surface of the workpiece, so as to achieve the function of uniformly grinding each area of the inclined surface of the conical workpiece. At the same time, when the polishing device is grinding the workpiece, the polishing device can also drive the polishing cooling device to start, so as to spray liquid onto the surface of the workpiece and the polishing device, so that the polishing cooling device can be started only when the polishing device is polishing the workpiece, reduce the temperature of the polishing area, and assist in polishing the workpiece, thereby improving the polishing accuracy of the workpiece. The polishing device can also drive the cleaning device to operate, and the cleaning device can collect and clean the liquid left on the bottom surface of the shell 1, so that the liquid with workpiece debris can be collected and wait for recycling, thereby improving the economic benefits of the equipment and protecting the cleanliness of the processing area.

[0066] This function achieves the following technical effects: when polishing a conical workpiece, the equipment can automatically adjust the polishing angle and cool the workpiece during polishing to improve the polishing accuracy. The equipment can also collect the cooling liquid for easy recycling.

[0067] The polishing device includes: a rotating and telescopic motor 201, a connecting disc 202, three polishing blocks 203, a horizontal slide 204, a vertical slide 205, a horizontal connecting spring 206, and a vertical connecting spring 207.

[0068] The rotary telescopic motor 201 is arranged on the outer side of the shell 1. The shell of the rotary telescopic motor 201 is fixedly connected to the outer side of the shell 1 through a support block, and the telescopic shaft of the rotary telescopic motor 201 passes through the side wall of the shell 1 and extends to the inside of the shell 1. The telescopic shaft of the rotary telescopic motor 201 is rotatably connected to the side wall of the shell 1, and the rotation axis is arranged horizontally.

[0069] The connecting disc 202 is arranged inside the shell 1, on the side of the telescopic rod of the rotating telescopic motor 201. The side surface of the connecting disc 202 is fixedly connected to one end face of the telescopic rod extending from the rotating telescopic motor 201 to the inside of the shell 1, and the other side surface is connected to the planar end face of the conical workpiece.

[0070] The transverse slide groove 204 is arranged inside the shell 1, on the side of the connecting disc 202 away from the rotary telescopic motor 201. The transverse slide groove 204 is arranged on the inner wall of the shell 1 opposite to the side where the connecting disc 202 is connected to the conical workpiece. The length of the transverse slide groove 204 is consistent with the length of the inner wall of the shell 1. The transverse slide groove 204 is also connected to the cleaning device.

[0071] The vertical slide groove 205 is arranged inside the shell 1, just above the middle of the horizontal slide groove 204. The vertical slide groove 205 is arranged on the inner wall of the shell 1 where the horizontal slide groove 204 is arranged, and is perpendicular to the setting direction of the horizontal slide groove 204.

[0072] The three grinding blocks 203 are respectively arranged horizontally inside the shell 1, and are respectively located on the side of the connecting disc 202 away from the rotating and telescopic motor 201. One end faces of two of the three grinding blocks 203, the A grinding block 203 and the B grinding block 203, are respectively arranged inside the horizontal slide groove 204, and are respectively slidably connected to the inner wall of the horizontal slide groove 204, and are respectively connected to the cleaning device. There is a gap between the A grinding block 203 and the B grinding block 203, and one end face of the C grinding block 203 among the three grinding blocks 203 is arranged inside the vertical slide groove 205, and is slidably connected to the inner wall of the vertical slide groove 205, and is connected to the polishing and cooling device. One end face of the three grinding blocks 203 close to the connecting disc 202 is respectively set as an inclined grinding surface, and the inclination angle of the inclined grinding surface matches the surface inclination angle of the conical end face of the conical workpiece.

[0073] The transverse connecting spring 206 is arranged inside the shell 1, between the A grinding block 203 and the B grinding block 203, and the transverse connecting spring 206 is arranged inside the transverse slide groove 204, and its two ends are respectively fixedly connected to the side surfaces of the A grinding block 203 and the B grinding block 203 close to each other.

[0074] The vertical connecting spring 207 is arranged inside the shell 1, below the C grinding block 203. The vertical connecting spring 207 is arranged inside the vertical slide groove 205, and the bottom end is fixedly connected to the inner bottom end surface of the vertical slide groove 205, and the top end is fixedly connected to the side of the C grinding block 203 close to the other two grinding blocks 203.

[0075] When the user wants to polish a conical workpiece, the user first places the plane of the workpiece on the connecting disc 202 so that the connecting disc 202 fixes the workpiece, and then the user starts the rotary telescopic motor 201 to rotate forward and extend through the controller 5. After the rotary telescopic motor 201 is started to rotate forward and extend, the rotary telescopic shaft can rotate and extend. The rotary telescopic shaft can rotate and extend to drive the connecting disc 202 to rotate and move toward the direction close to the three grinding blocks 203. The rotation and movement of the connecting disc 202 drive the workpiece to rotate and move until the conical inclined surface of the workpiece gradually contacts the inclined grinding surfaces of the three grinding blocks 203. When the inclined grinding surfaces of the three grinding blocks 203 contact the conical inclined surface of the workpiece, the three grinding blocks 203 will grind and polish the conical surface of the workpiece. At the same time, the movement of the workpiece will also continuously squeeze the three grinding blocks 203.

[0076] When the workpiece squeezes the three grinding blocks 203, the grinding blocks A 203 and B 203 are squeezed and move away from each other along the transverse groove 204, and respectively drive the cleaning devices to move. The grinding blocks A 203 and B 203 are squeezed and move along the transverse groove 204, which will apply tension to the transverse connecting spring 206. The transverse connecting spring 206 will extend after receiving the pressure, thereby expanding the distance between the grinding blocks A 203 and B 203.

[0077] After being squeezed, grinding block C 203 moves upward along vertical slot 205. This upward movement of grinding block C drives vertical connecting rod 306 upward, exerting tension on vertical connecting spring 207, causing it to extend. As grinding blocks A, B, and C move, the spacing between them increases, adjusting the heights of the inclined grinding surfaces of the three grinding blocks 203 to match the different areas of the workpiece's conical surface. This continues until the workpiece fully enters the spacing between the three grinding blocks 203, at which point the grinding surfaces of the three grinding blocks 203 begin grinding the cylindrical rear end of the workpiece.

[0078] When the user wants to take out the workpiece, the user can control the rotary telescopic motor 201 to reverse and retract through the controller 5. After the rotary telescopic motor 201 is reversed and retracted, the rotary telescopic shaft can rotate and retract. The rotation and retraction of the rotary telescopic shaft drive the connecting disc 202 to rotate and move in the direction away from the three grinding blocks 203. The rotation and movement of the connecting disc 202 drive the workpiece to rotate and move until the workpiece can leave the space formed between the three grinding blocks 203. When the three grinding blocks 203 rotate to leave the space formed between the three grinding blocks 203, the three grinding blocks 203 will still grind the cylindrical rear end of the workpiece. At the same time, the inclined grinding surfaces of the three grinding blocks 203 will still grind and polish the conical surface of the workpiece. At the same time, when the cylindrical rear end of the workpiece leaves the flat grinding surfaces of the three grinding blocks 203, the pressure applied to the three grinding blocks 203 will gradually decrease until the workpiece completely leaves the three grinding blocks 203.

[0079] When the workpiece gradually reduces the pressure applied to the three grinding blocks 203, the A grinding block 203 and the B grinding block 203 are reduced and squeezed, which will reduce the pressure applied to the horizontal connecting spring 206. The horizontal connecting spring 206 will gradually shorten after the pressure is reduced, and drive the A grinding block 203 and the B grinding block 203 to move closer to each other. The A grinding block 203 and the B grinding block 203 move closer to each other, driving the cleaning device to move. The C grinding block 203 will reduce the pressure applied to the vertical connecting spring 207 after the pressure is reduced, and the vertical connecting spring The pressure on the extended spring 207 decreases, driving the C grinding block 203 downward. The downward movement of the C grinding block 203 drives the polishing and cooling device downward. When the A, B, and C grinding blocks 203 move closer to each other, the distance between them decreases, thereby adjusting the height of the inclined grinding surfaces of the three grinding blocks 203 again until they return to their original position, thereby matching the conical surface of the workpiece again. The conical surface of the workpiece is then ground until the workpiece completely leaves the inclined grinding surfaces of the three grinding blocks 203. The workpiece is then collected.

[0080] The sides of the three grinding blocks 203 that are close to each other are respectively set as grinding surfaces, and the mesh counts of the grinding surfaces are consistent. The lengths of the three grinding blocks 203 are greater than the length of the conical workpiece.

[0081] The length of the three grinding blocks 203 is greater than the length of the workpiece, which can prevent the conical top of the workpiece from contacting the inner wall of the housing 1 and damaging the workpiece.

[0082] The connecting disc 202 is configured as an electromagnetic suction cup and is electrically connected to the controller 5 .

[0083] Setting the connecting disc 202 as an electromagnetic chuck can effectively fix the planes of conical workpieces of different sizes.

[0084] The polishing and cooling device includes: a right-angle tube 208 , a liquid storage box 301 , a spraying pipe 302 , a plurality of spraying heads 303 , a plurality of liquid leakage holes, a water valve 304 , a vertical connecting rod 306 , and a handle slot 307 .

[0085] The liquid storage box 301 is arranged above the housing 1 , and the outer bottom surface of the liquid storage box 301 is fixedly connected to the top surface of the housing 1 .

[0086] The right-angle tube 208 is arranged inside the shell 1, above the C grinding block 203. One end of the vertical tube of the right-angle tube 208 passes through the top of the shell 1 and the bottom of the liquid storage box 301, and is connected to the interior of the liquid storage box 301. The horizontal tube of the right-angle tube 208 is parallel to the inner bottom surface of the shell 1.

[0087] The water valve 304 is disposed inside the housing 1 and between the right-angle tube 208 and the connecting disc 202 . One end of the water valve 304 is communicated with the transverse tube port of the right-angle tube 208 .

[0088] The spray pipe 302 is arranged inside the housing 1, between the right-angle tube 208 and the connecting disc 202, above the C grinding block 203, and one end of the spray pipe 302 is connected to the other end of the water valve 304, and the other end is closed.

[0089] Several spray heads 303 are respectively arranged inside the housing 1 and between the spray pipe 302 and the C grinding block 203 . The input ports of the several spray heads 303 respectively pass through the side of the spray pipe 302 and communicate with the interior of the spray pipe 302 .

[0090] The vertical connecting rod 306 is arranged inside the housing 1, on the side of the water valve 304 and above the C grinding block 203, and the bottom end of the vertical connecting rod 306 is fixedly connected to the top surface of the C grinding block 203.

[0091] The handle slot 307 is provided at the handle end of the vertical connecting rod 306 close to the water valve 304 . The handle slot 307 is a through-hole slot, and the handle of the water valve 304 passes through the handle slot 307 .

[0092] A plurality of liquid leakage holes are respectively provided on the side of the C grinding block 203 , and the ports correspond to the spraying directions of the plurality of spray heads 303 .

[0093] When the C grinding block 203 is squeezed, it will move upward along the vertical slide groove 205, and the C grinding block 203 will move upward, driving the vertical connecting rod 306 to move upward. The upward movement of the vertical connecting rod 306 will push the handle of the water valve 304 to rotate upward through the handle groove 307. The upward rotation of the handle of the water valve 304 will open the internal switch of the water valve 304. After the internal switch of the water valve 304 is turned on, the liquid inside the liquid storage tank 301 will pass through the right-angle tube 208 and the water valve 304 into the spray pipe 302, and then pass through several spray heads 303 to be sprayed onto the surface of the workpiece and the surface of the C grinding block 203. When the liquid falls on the surface of the C grinding block 203, it will pass through several leakage holes and enter the surface of the workpiece below the C grinding block 203, thereby reducing the temperature of the three grinding blocks 203 when polishing the workpiece surface.

[0094] When the C grinding block 203 is squeezed, it moves downward along the vertical slide groove 205. The downward movement of the C grinding block 203 drives the vertical connecting rod 306 to move downward. The downward movement of the vertical connecting rod 306 pushes the handle of the water valve 304 to rotate downward through the handle groove 307. The downward rotation of the handle of the water valve 304 gradually closes the internal switch of the water valve 304 until the internal switch of the water valve 304 is completely closed. The liquid inside the liquid storage tank 301 stops passing through the right-angle tube 208 and the water valve 304 to enter the spray pipe 302, thereby stopping the injection of liquid into the multiple spray heads 303 to avoid waste of liquid.

[0095] The liquid in the liquid storage box 301 is polishing liquid.

[0096] Setting the liquid inside the liquid storage box 301 as polishing liquid can not only reduce the temperature of the workpiece during polishing, but also assist in the polishing of the workpiece.

[0097] Some of the spray heads 303 are oscillating spray heads 303 .

[0098] The plurality of spray heads 303 are swing-type spray heads 303 that can effectively and evenly spray the polishing liquid onto the surface of the workpiece.

[0099] The polishing and cooling device further includes a stirring device, which is disposed inside the liquid storage box 301 , connected to the inner wall of the liquid storage box 301 , and electrically connected to the controller 5 .

[0100] By setting a stirring device inside the polishing and cooling device, the user can start the stirring device to ensure that the polishing liquid is always in the best working condition, avoiding the precipitation of the polishing liquid and causing its working performance to deteriorate.

[0101] The cleaning device includes: two push rods 401 , two return springs 402 , two cleaning rods 403 , three liquid leakage ports 404 , and two sliding blocks 405 .

[0102] The two push rods 401 are respectively arranged horizontally inside the horizontal slide groove 204, and are respectively located on the side of the grinding block A 203 and the grinding block B 203. One end of the two push rods 401 is fixedly connected to the side of the grinding block A 203 and the grinding block B 203 away from the horizontal connecting spring 206.

[0103] The two sliding blocks 405 are respectively arranged inside the horizontal slide groove 204, respectively on the side of the other end of the two push rods 401, and are respectively slidably connected to the inner wall of the horizontal slide groove 204, and the side surfaces of the two sliding blocks 405 are respectively in contact with the other end surfaces of the two push rods 401.

[0104] The two return springs 402 are respectively arranged horizontally inside the horizontal slide groove 204, and are respectively located on the sides of the two sliding blocks 405 away from the two push rods 401. One end of the two return springs 402 is fixedly connected to the inner wall end face of the horizontal slide groove 204, and the other end is fixedly connected to the side of the two sliding blocks 405 away from the two push rods 401.

[0105] The two cleaning rods 403 are right-angle rods and are respectively arranged inside the shell 1, on the side of the A grinding block 203 and the B grinding block 203 away from the horizontal connecting spring 206, and the vertical rod sides of the two cleaning rods 403 are fixedly connected to the sides of the two sliding blocks 405, and the horizontal rods of the two cleaning rods 403 are respectively above the inner bottom surface of the shell 1, and are respectively parallel to the inner bottom surface of the shell 1, and scrapers are respectively provided on the sides close to the inner bottom surface of the shell 1, and the scrapers are in contact with the inner bottom surface of the shell 1.

[0106] Three liquid leakage ports 404 are respectively arranged at the bottom of the housing 1, and two of the liquid leakage ports are close to two opposite side walls of the housing 1, and the other liquid leakage port is directly below the C grinding block 203. The three liquid leakage ports 404 are connected to the interior of the housing 1, and the arrangement direction is parallel to the arrangement direction of the three grinding blocks 203. In addition, two of the three liquid leakage ports 404 that are close to each other are respectively located on the left and right sides of one of the two cleaning rods 403.

[0107] When the A grinding block 203 and the B grinding block 203 are squeezed and move away from each other along the horizontal slide groove 204, the A grinding block 203 and the B grinding block 203 move in the direction away from each other and respectively drive the two push rods 401 to move along the horizontal slide groove 204 toward the direction close to the two sliding blocks 405. The movement of the two push rods 401 will contact the sides of the two sliding blocks 405 and push the two sliding blocks 405 to move toward the direction close to the two return springs 402. The movement of the two sliding blocks 405 toward the direction close to the two return springs 402 will apply pressure to the two return springs 402 and drive the two cleaning rods 403 to move. After receiving the pressure, the two return springs 402 will shorten and drive the two sliding blocks 405 to move again toward the direction close to the two return springs 402 until the two return springs 402 are completely shortened to the minimum length.

[0108] The movement of the two cleaning rods 403 will drive the scrapers on the two cleaning rods 403 to move. The movement of the scrapers can scrape the polishing liquid mixed with workpiece debris falling on the bottom surface of the inner wall of the shell 1 into the two leakage ports near the two side walls of the shell 1, and then leave the inside of the shell 1.

[0109] When the A grinding block 203 and the B grinding block 203 approach each other, the A grinding block 203 and the B grinding block 203 approach each other and respectively drive the two push rods 401 to move along the horizontal slide groove 204 in the direction away from the two sliding blocks 405. The two push rods 401 stop moving and apply pressure to the two sliding blocks 405. After the two sliding blocks 405 stop being subjected to pressure, they will stop applying pressure to the two return springs 402. After the two return springs 402 stop being subjected to pressure, they will drive the two sliding blocks 405 to move in the direction close to the two push rods 401 until the two return springs 402 are completely restored.

[0110] The movement of the two sliding blocks 405 drives the two cleaning rods 403 to move. The movement of the two cleaning rods 403 drives the scrapers on the two cleaning rods 403 to move closer to each other. The movement of the scrapers can scrape the polishing liquid mixed with workpiece debris that falls on the bottom surface of the inner wall of the shell 1 to the inside of the liquid leakage port directly below the C grinding block 203 and leave the inside of the shell 1.

[0111] The cleaning device also includes a sedimentation tank 406. The sedimentation tank 406 is arranged below the housing 1, and the top surface is fixedly connected to the bottom surface of the housing 1 and communicates with the interior of the housing 1 through three leakage ports 404. The interior of the sedimentation tank 406 is provided with an inclined plate, and the surface of the inclined plate is a stepped surface.

[0112] When the polishing liquid mixed with workpiece debris leaves the inside of the shell 1 through the three leakage ports 404, it will fall into the sedimentation box 406, and then accelerate the sedimentation through the inclined plate inside the sedimentation box 406, so that the polishing liquid mixed with workpiece debris can be purified, thereby making it convenient for users to collect reusable polishing liquid, thereby improving the utilization rate of the polishing liquid.

[0113] Working process:

[0114] When the user wants to polish the conical workpiece, the user first places the flat surface of the workpiece on the connecting disc 202, and then starts the connecting disc 202 through the controller 5. The connecting disc 202 can adsorb the flat surface of the workpiece when it is started. When the connecting disc 202 adsorbs the workpiece, the user starts the rotary telescopic motor 201 through the controller 5 to rotate and extend. After the rotary telescopic motor 201 is started to rotate and extend, the rotary telescopic shaft can rotate and extend. The rotary telescopic shaft can rotate and extend to drive the connecting disc 202 to rotate and move toward the direction close to the three grinding blocks 203. The rotation and movement of the connecting disc 202 drive the workpiece to rotate and move until the conical inclined surface of the workpiece gradually contacts the inclined grinding surfaces of the three grinding blocks 203. When the inclined grinding surfaces of the three grinding blocks 203 contact the conical inclined surface of the workpiece, the three grinding blocks 203 will grind and polish the conical surface of the workpiece. At the same time, the movement of the workpiece will also continuously squeeze the three grinding blocks 203.

[0115] When the workpiece squeezes the three grinding blocks 203, the grinding blocks A 203 and the grinding blocks B 203 are squeezed and move away from each other along the transverse groove 204, and respectively drive the two push rods 401 to move along the transverse groove 204 toward the direction close to the two sliding blocks 405. The grinding blocks A 203 and the grinding blocks B 203 are squeezed and move along the transverse groove 204, which will apply tension to the transverse connecting spring 206. After receiving the pressure, the transverse connecting spring 206 will extend, thereby expanding the distance between the grinding blocks A 203 and the grinding blocks B 203.

[0116] After being squeezed, grinding block C 203 moves upward along vertical slot 205. This upward movement of grinding block C drives vertical connecting rod 306 upward, exerting tension on vertical connecting spring 207, causing it to extend. As grinding blocks A, B, and C move, the spacing between them increases, adjusting the heights of the inclined grinding surfaces of the three grinding blocks 203 to match the different areas of the workpiece's conical surface. This continues until the workpiece fully enters the spacing between the three grinding blocks 203, at which point the grinding surfaces of the three grinding blocks 203 begin grinding the cylindrical rear end of the workpiece.

[0117] When the vertical connecting rod 306 moves upward, the upward movement of the vertical connecting rod 306 will push the handle of the water valve 304 to rotate upward through the handle slot 307. The upward rotation of the handle of the water valve 304 will open the internal switch of the water valve 304. After the internal switch of the water valve 304 is turned on, the polishing liquid inside the liquid storage tank 301 will pass through the right-angle tube 208 and the water valve 304 into the spray pipe 302, and then pass through several spray heads 303 to be sprayed onto the surface of the workpiece and the surface of the C grinding block 203. When the polishing liquid falls on the surface of the C grinding block 203, it will pass through several leakage holes into the surface of the workpiece below the C grinding block 203, thereby assisting the three grinding blocks 203 in polishing the surface of the workpiece.

[0118] When the two push rods 401 move along the horizontal slide groove 204 toward the direction close to the two sliding blocks 405, the two push rods 401 move and contact the sides of the two sliding blocks 405, and push the two sliding blocks 405 to move toward the direction close to the two return springs 402. The movement of the two sliding blocks 405 toward the direction close to the two return springs 402 will apply pressure to the two return springs 402 and drive the two cleaning rods 403 to move. After receiving the pressure, the two return springs 402 will shorten and drive the two sliding blocks 405 to move again toward the direction close to the two return springs 402 until the two return springs 402 are completely shortened to the minimum length.

[0119] The movement of the two cleaning rods 403 will drive the scrapers on the two cleaning rods 403 to move. The movement of the scrapers can scrape the polishing liquid of the mixed workpiece debris that falls on the bottom surface of the inner wall of the shell 1 to the inside of the two leakage ports close to the two side walls of the shell 1, and finally fall into the sedimentation box 406, and then pass through the inclined plate of the sedimentation tank to complete the precipitation and recovery of the polishing liquid of the mixed workpiece debris.

[0120] When the user wants to take out the workpiece, the user can control the rotary telescopic motor 201 to reverse and retract through the controller 5. After the rotary telescopic motor 201 is reversed and retracted, the rotary telescopic shaft can rotate and retract. The rotation and retraction of the rotary telescopic shaft drive the connecting disc 202 to rotate and move in the direction away from the three grinding blocks 203. The rotation and movement of the connecting disc 202 drive the workpiece to rotate and move until the workpiece can leave the space formed between the three grinding blocks 203. When the three grinding blocks 203 rotate to leave the space formed between the three grinding blocks 203, the three grinding blocks 203 will still grind the cylindrical rear end of the workpiece. At the same time, the inclined grinding surfaces of the three grinding blocks 203 will still grind and polish the conical surface of the workpiece. At the same time, when the cylindrical rear end of the workpiece leaves the flat grinding surfaces of the three grinding blocks 203, the pressure applied to the three grinding blocks 203 will gradually decrease until the workpiece completely leaves the three grinding blocks 203.

[0121] When the workpiece gradually reduces the pressure exerted on the three grinding blocks 203, the A grinding block 203 and the B grinding block 203 are reduced and squeezed, which will reduce the pressure exerted on the horizontal connecting spring 206. The horizontal connecting spring 206 will gradually shorten after the pressure is reduced, and respectively drive the A grinding block 203 and the B grinding block 203 to approach each other. The A grinding block 203 and the B grinding block 203 approach each other and respectively drive the two push rods 401 to move along the horizontal slide 204 in the direction away from the two sliding blocks 405. After the pressure on the C grinding block 203 is reduced, the pressure on the vertical connecting spring will be reduced. When the A, B, and C grinding blocks 203 move closer to each other, the distance between the A, B, and C grinding blocks 203 will become smaller, thereby adjusting the height of the inclined grinding surfaces of the three grinding blocks 203 again until they return to their original positions, so as to match the conical surface of the workpiece again and grind the conical surface of the workpiece until the workpiece completely leaves the inclined grinding surfaces of the three grinding blocks 203.

[0122] When the vertical connecting rod 306 moves downward, the downward movement of the vertical connecting rod 306 will pull the handle of the water valve 304 downward through the handle groove 307. The downward rotation of the handle of the water valve 304 will gradually close the internal switch of the water valve 304 until the internal switch of the water valve 304 is completely closed. The polishing liquid inside the liquid storage tank 301 will stop passing through the right-angle tube 208 and the water valve 304 into the spray pipe 302, thereby stopping the injection of polishing liquid into the several spray heads 303 to avoid waste of polishing liquid.

[0123] When the two push rods 401 move along the horizontal sliding groove 204 in the direction away from the two sliding blocks 405, the two push rods 401 stop moving and apply pressure to the two sliding blocks 405. After the two sliding blocks 405 stop being under pressure, they will stop applying pressure to the two return springs 402. After the two return springs 402 stop being under pressure, they will drive the two sliding blocks 405 to move in the direction close to the two push rods 401 until the two return springs 402 are completely restored.

[0124] The movement of the two sliding blocks 405 drives the two cleaning rods 403 to move. The movement of the two cleaning rods 403 drives the scrapers on the two cleaning rods 403 to move closer to each other. The movement of the scrapers can scrape the polishing liquid mixed with workpiece debris that falls on the bottom surface of the inner wall of the shell 1 to the inside of the leakage port directly below the C grinding block 203, and finally falls into the sedimentation box 406, completing the function of collecting the polishing liquid again and purifying the sediment.

[0125] The above embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.
