Description

Technical Field

[0001] This invention relates to the field of precision parts processing technology, specifically a multi-axis linkage automatic grinding machine. Background Technology

[0002] An automatic grinding machine is a mechanical device used to automate the grinding process on the surface of workpieces to achieve a smooth, flat surface or meet specific precision requirements. It is widely used in various fields of manufacturing, significantly improving processing efficiency, accuracy, and consistency by replacing manual grinding.

[0003] Traditional automatic grinding machines work by moving the workpiece on the clamping device closer to the grinding wheel for grinding. When multiple workpieces are processed at the same time, the grinding effect on each workpiece is often different because the multiple workpieces are in different positions on the grinding wheel, which cannot ensure the grinding accuracy of each workpiece. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-axis linkage automatic grinding machine to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The multi-axis linkage automatic grinding machine includes a frame base, four universal casters mounted on the bottom of the frame base, a base plate mounted on the top of the frame base, two guide pillars mounted on the base plate, guide pillar boxes slidably mounted on the two guide pillars, a pneumatic push rod mounted on the bottom of the guide pillar box, a reducer mounted on the guide pillar box, a baffle mounted outside the reducer, an LED light mounted on the inner wall of the baffle, a connector mounted on the output shaft of the reducer, a clamping component mounted on the other end of the connector, a rotating sleeve mounted on the base plate, a rotating shaft rotatably mounted inside the rotating sleeve, a grinding wheel mounted on the top of the rotating shaft, and a large pulley mounted on the bottom of the rotating shaft. A drive motor is installed inside the machine base, and a small pulley is mounted on the output shaft of the drive motor. A belt is fitted between the small pulley and the large pulley. A housing is installed outside the frame machine base. When the workpiece to be ground is clamped onto the clamping device, the pneumatic push rod drives the reducer on the guide column box to descend. When the workpiece contacts the surface of the grinding wheel, the guide column box stops descending. At this time, the reducer drives the clamping device to rotate, and at the same time, the drive motor drives the small pulley to rotate. The small pulley drives the large pulley to rotate through the belt, thereby causing the grinding wheel on the rotating shaft to rotate. The clamping device drives multiple workpieces to rotate, so that each workpiece is in a position with the same linear velocity of the grinding wheel during grinding, so that the grinding degree of multiple workpieces is uniformly ground by the surface of the grinding wheel, ensuring that the processing accuracy of the workpieces in the same batch is the same.

[0006] As a preferred technical solution, the clamping component includes a connecting rod, a mounting hole, a conical hole, a ball bearing; a sliding sleeve, a sliding hole, a spring, a rotating pin, an annular groove, a protective disc, a central clamping disc, a clamping hole, a mounting rod, and a slot.

[0007] A connecting rod is installed at the bottom of the connector, and a sliding sleeve is slidably mounted on the connecting rod. An annular groove is formed on the inner wall of the sliding sleeve, and a protective disc is installed on the sliding sleeve. A sliding hole is formed at the bottom of the sliding sleeve, and a rotating pin is slidably mounted within the sliding hole. The upper end of the rotating pin is connected to the bottom end of the sliding hole by a spring. An installation hole is formed at the bottom of the connecting rod, and a conical hole is formed on the side wall of the connecting rod. A ball bearing is slidably mounted within the conical hole, and an installation rod is installed within the installation hole. A retaining groove is formed at the top end of the installation rod, and the ball bearing is retained within the retaining groove. A central clamping plate is installed at the bottom, and multiple clamping holes are opened on the central clamping plate. When clamping the workpiece to be ground, first press down on the protective disc. The protective disc drives the sliding sleeve to slide down on the connecting rod. When the annular groove descends to the position of the conical hole, the ball in the conical hole loses pressure and rolls into the annular groove, thus disengaging from the slot. At this time, the mounting rod on the central clamping plate is removed from the mounting hole. Then, the protective disc spring is released to drive the sliding sleeve to return to its original position. After the workpiece to be ground is installed in the clamping hole, the mounting rod is installed in the mounting hole, thereby realizing the quick clamping of the workpiece to be ground.

[0008] As a preferred technical solution, a water-blocking cover is installed on the inner wall of the outer shell. The water-blocking cover is located between the grinding wheel and the central clamping plate. A circular hole is opened on the water-blocking cover. The circular hole is located directly below the central clamping plate. A barrier is installed on the circular hole.

[0009] As a preferred technical solution, the frame base is also provided with control components, repair components, protection components, cooling components and cleaning components;

[0010] The control component sets up various pre-grinding programs and controls the operation of the dressing component, protection component, cooling component, and cleaning component. The dressing component repairs the surface of the grinding wheel and can perform intermittent dressing during operation. The protection component protects personnel and isolates processing dust during processing. The cooling component cools the grinding wheel and workpiece during processing. The cleaning component cleans the surface of the water baffle after processing.

[0011] As a preferred technical solution, the control components include a control cabinet, a touch control panel, and a cooling fan;

[0012] A control cabinet is mounted on the base plate. A touch control panel is mounted on one side of the control cabinet. A cooling fan is mounted on the side of the control cabinet away from the touch control panel. The touch control panel is electrically connected to the reducer and the pneumatic push rod. When the workpiece is being ground, the corresponding pre-grinding program can be selected through the touch control panel to control the grinding time, accuracy and amount of grinding.

[0013] As a preferred technical solution, the repair assembly includes a fixed frame, a mounting plate, a slide rail, a moving block, a storage plate, a stepper motor, a hollow rotating platform, a connecting seat, a lever, and a grinding wheel;

[0014] A mounting bracket is installed on the inner wall of the outer casing. A mounting plate is mounted on the mounting bracket. A slide rail is mounted on the mounting plate. A moving block is mounted on the slide rail. A shelf is mounted on the moving block. A stepper motor is mounted on the shelf. A hollow rotating platform is mounted on the output shaft of the stepper motor. A connecting seat is mounted at the bottom of the hollow rotating platform. A lever is mounted on the connecting seat. A grinding wheel rod is mounted at the end of the lever, perpendicular to the lever. An arc-shaped hole is provided on the water-blocking cover, through which the grinding wheel rod passes. The stepper motor is electrically connected to the touch control panel. When the grinding wheel's smoothing effect deteriorates, the position of the moving block on the slide rail is controlled, putting the stepper motor in the working position. At this time, the stepper motor drives the lever on the hollow rotating platform to rotate in an arc, thereby driving the grinding wheel rod, perpendicular to the lever, to dress the grinding wheel. This reduces the time spent removing, repairing, and reinstalling the grinding wheel, achieving the effect of reducing maintenance time and saving manpower.

[0015] As a preferred technical solution, the protective assembly includes a rotating bracket, a pen-type push rod, a lower swing arm, an upper swing arm, and a protective cover;

[0016] A rotating bracket is mounted on the base plate. A lower swing arm and an upper swing arm are rotatably mounted on the rotating bracket, and the upper and lower swing arms are parallel to each other. A pen-type push rod is rotatably mounted on the top of the rotating bracket. The other end of the pen-type push rod is rotatably connected to the end of the lower swing arm through a cylindrical pin. A protective cover is mounted on the lower and upper swing arms, and the protective cover fits in close to the outer shell. The pen-type push rod is electrically connected to the touch control panel. When the equipment starts processing, the pen-type push rod drives the upper and lower swing arms to rotate downward, moving the protective cover to the working position, thereby isolating and protecting the environment from metal chips and dust generated during grinding.

[0017] As a preferred technical solution, the cooling assembly includes a water tank, a return water inlet, a water pump, a float valve, a filter frame, a ball valve, and a collection frame;

[0018] A water tank is placed inside the frame base. Four casters and two ball valves are installed at the bottom of the water tank. A return water inlet is located at the top of the water tank, and a filter frame is installed inside the return water inlet. A float valve is installed on the side wall of the return water inlet near the top. A water pump is installed at the top of the water tank. A fixing hole is provided on the water baffle plate. The output end of the water pump is connected to the fixing hole via a cooling water pipe. A collection frame is installed at the bottom of the water baffle plate, and the output end of the collection frame is connected to the return water inlet via a return pipe. When grinding the workpiece, the water pump starts, and the water in the tank flows through the cooling pipe to the surface of the grinding wheel to cool it down and remove metal powder from the surface of the grinding wheel, improving the grinding effect. After grinding, the water enters the return water inlet through the return pipe on the collection frame, is filtered by the filter frame, and then re-enters the water tank, realizing the recycling of water resources.

[0019] As a preferred technical solution, the cleaning component includes a first electric slide rail, a movable nozzle, a water inlet, a second electric slide rail, a slider, an electric push rod, a base plate, a telescopic rod, a cleaning rod, a cylindrical brush, a soft brush, a lifting rod, a support rod, an L-shaped fixing plate, a cleaning plate, a square hole, and a cleaning wheel;

[0020] A first electric slide rail is installed on the side of the water-blocking cover away from the control cabinet. A movable nozzle is slidably mounted on the first electric slide rail. The movable nozzle has a water inlet at its top, and the water inlet is connected to a water pump via a cleaning water pipe. A solenoid valve is installed on the cleaning water pipe. A second electric slide rail is installed on the side of the water-blocking cover closer to the control cabinet. A slider is slidably mounted on the second electric slide rail. An electric push rod is mounted on the slider. A base plate is installed at the end of the electric push rod. Multiple telescopic rods are mounted on the base plate. A cleaning rod is vertically mounted on the telescopic rod. A cylindrical brush is rotatably mounted on the cleaning rod. A soft brush is mounted at the bottom of the cleaning rod. A lifting rod is mounted on the second electric slide rail. A support rod is mounted on the lifting rod. An L-shaped fixing plate is installed at the end of the support rod. Multiple cleaning plates are mounted on the L-shaped fixing plate. Each of the multiple cleaning plates has multiple square holes. Cleaning wheels are rotatably installed inside each of the square holes. The second electric slide rail is electrically connected to the electric push rod. After the workpiece is processed, the solenoid valve opens, and the water pump delivers water to the moving nozzle through the cleaning water pipe. At the same time, the first electric slide rail drives the moving nozzle to rinse the water baffle plate while moving. After rinsing, the second electric slide rail drives the slider to move intermittently to the other end. During the stop period, the electric push rod drives the telescopic rod to move. The telescopic rod drives the cylindrical brush and soft brush on the cleaning rod to move back and forth with the electric push rod. When the electric push rod completes one reciprocating movement, it returns to the initial position. After cleaning, the slider returns to the initial position. At this time, the lifting rod drives the L-shaped fixed plate to descend, so that the cleaning plate on the L-shaped fixed plate is between the adjacent cylindrical brushes. At this time, the electric push rod moves back and forth, so that the cylindrical brush and the cleaning wheel rotate relative to each other to squeeze and clean. Thus, the water baffle plate is fully and automatically cleaned through rinsing and reciprocating cleaning.

[0021] As a preferred technical solution, the slider moves intermittently on the second electric slide rail, and the intermittent time is the duration of one reciprocating motion of the electric push rod.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. This application can process workpieces with various precision requirements by controlling the rotational speed of the grinding wheel and the rotational speed of the clamping parts driven by the reducer. By increasing the rotational speed of the reducer, the grinding accuracy of multiple workpieces on the clamping parts can be improved. When clamping the workpiece, the protective disc is pressed down to drive the sliding sleeve to slide down on the connecting rod. When the annular groove descends to the position of the conical hole, the ball in the conical hole loses pressure and rolls into the annular groove, thus disengaging from the slot. At this time, the mounting rod on the central clamping disc is removed from the mounting hole. Then, the protective disc spring is released to drive the sliding sleeve to reset. After the workpiece to be ground is installed in the clamping hole, the mounting rod is installed in the mounting hole, thereby realizing the rapid clamping of the workpiece to be ground.

[0024] 2. This application repairs the surface of the grinding wheel by setting up a dressing component. When the grinding wheel's smoothing effect deteriorates, the position of the slider on the slide rail is controlled to put the stepper motor in the working position. At this time, the stepper motor drives the lever on the hollow rotating platform to rotate in an arc, thereby driving the grinding wheel grinding rod perpendicular to the lever to dress the grinding wheel. This reduces the time required to remove the grinding wheel for repair and reinstall it, achieving the effect of reducing maintenance time and saving manpower.

[0025] 3. This application uses a first electric slide rail to drive a moving nozzle to flush the water-retaining cover plate while it is moving. The second electric slide rail drives a slider to move intermittently to the other end. During the stop period, the electric push rod drives the telescopic rod to move. The telescopic rod drives the cylindrical brush and soft brush on the cleaning rod to move back and forth with the electric push rod. By positioning the cleaning plate on the L-shaped fixed plate between adjacent cylindrical brushes, the electric push rod moves back and forth, causing the cylindrical brush and cleaning wheel to rotate relative to each other and squeeze for cleaning. Thus, the water-retaining cover plate is fully and automatically cleaned through flushing and reciprocating cleaning. Attached Figure Description

Detailed Implementation

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Example: Figures 1-7As shown, the present invention provides a technical solution for a multi-axis linkage automatic grinding machine. This multi-axis linkage automatic grinding machine includes a frame base 11, four casters 12 mounted at the bottom of the frame base 11, a base plate 13 mounted at the top of the frame base 11, two guide pillars 14 mounted on the base plate 13, guide pillar boxes 141 slidably mounted on the two guide pillars 14, a pneumatic push rod 15 mounted at the bottom of the guide pillar boxes 141, a reducer 16 mounted on the guide pillar boxes 141, a baffle 161 mounted outside the reducer 16, an LED light 162 mounted on the inner wall of the baffle 161, a connector 17 mounted on the output shaft of the reducer 16, a clamping member 18 mounted at the other end of the connector 17, a rotating sleeve 19 mounted on the base plate 13, a rotating shaft 20 rotatably mounted inside the rotating sleeve 19, a grinding wheel 21 mounted on the top of the rotating shaft 20, and a large pulley 22 mounted on the bottom of the rotating shaft 20. A drive motor 24 is installed inside the frame base 11. A small pulley 23 is installed on the output shaft of the drive motor 24. A belt is fitted between the small pulley 23 and the large pulley 22. A housing 25 is installed outside the frame base 11. When the workpiece to be ground is clamped onto the clamping member 18, the pneumatic push rod 15 drives the reducer 16 on the guide column box 141 to descend. When the workpiece to be ground contacts the surface of the grinding wheel 21, the guide column box 141 stops descending. At this time, the reducer 16 drives the clamping member 18 to rotate. At the same time, the drive motor 24 drives the small pulley 23 to rotate. The small pulley 23 drives the large pulley 22 to rotate through the belt, thereby causing the grinding wheel 21 on the rotating shaft 20 to rotate. The clamping member 18 drives multiple workpieces to rotate, so that each workpiece is in the same position with the same linear velocity of the grinding wheel 21 during grinding. This ensures that the multiple workpieces to be ground are ground to a uniform degree on the surface of the grinding wheel 21, and ensures that the processing accuracy of the same batch of workpieces is the same.

[0044] like Figures 4-8 and Figure 10 As shown, the clamping component 18 includes a connecting rod 181, a mounting hole 1811, a conical hole 1812, a ball bearing 1813; a sliding sleeve 182, a sliding hole 1821, a spring 1822, a rotating pin 1823, an annular groove 1824, a protective disc 183, a central clamping disc 184, a clamping hole 1841, a mounting rod 185, and a slot 1851;

[0045] A connecting rod 181 is installed at the bottom of the connector 17. A sliding sleeve 182 is slidably installed on the connecting rod 181. An annular groove 1824 is formed on the inner wall of the sliding sleeve 182. A protective disc 183 is installed on the sliding sleeve 182. A sliding hole 1821 is formed at the bottom of the sliding sleeve 182. A rotating pin 1823 is slidably installed in the sliding hole 1821. The upper end of the rotating pin 1823 is connected to the bottom end of the sliding hole 1821 by a spring 1822. A mounting hole 1811 is formed at the bottom of the connecting rod 181. A conical hole 1812 is formed on the side wall of the connecting rod 181. A ball bearing 1813 is slidably installed in the conical hole 1812. A mounting rod 185 is installed in the mounting hole 1811. A slot 1851 is formed at the top end of the mounting rod 185, and the ball bearing 1813 is locked in the slot 1851. The bottom of the mounting rod 185... The unit is equipped with a central clamping plate 184, which has multiple clamping holes 1841. When clamping the workpiece to be ground, the protective disc 183 is pressed down first. The protective disc 183 drives the sliding sleeve 182 to slide down on the connecting rod 181. When the annular groove 1824 descends to the position of the conical hole 1812, the ball 1813 in the conical hole 1812 loses pressure and rolls into the annular groove 1824, thus disengaging from the slot 1851. At this time, the mounting rod 185 on the central clamping plate 184 is removed from the mounting hole 1811. The protective disc 183 spring 1822 is then released, causing the sliding sleeve 182 to return to its original position. After the workpiece to be ground is installed in the clamping hole 1841, the mounting rod 185 is then installed into the mounting hole 1811, thereby achieving quick clamping of the workpiece to be ground.

[0046] A water-blocking cover plate 26 is installed on the inner wall of the outer shell 25. The water-blocking cover plate 26 is located between the grinding wheel 21 and the central clamping plate 184. A round hole 261 is opened on the water-blocking cover plate 26. The round hole 261 is located directly below the central clamping plate 184. A retaining wall 263 is installed on the round hole 261.

[0047] The frame base 11 is also equipped with a control component 3, a repair component 4, a protection component 5, a cooling component 6, and a cleaning component 7;

[0048] The control component 3 sets up various pre-grinding programs and controls the operation of the dressing component 4, protection component 5, cooling component 6, and cleaning component 7. The dressing component 4 repairs the surface of the grinding wheel 21 and can perform intermittent dressing during operation. The protection component 5 protects personnel and isolates processing dust during processing. The cooling component 6 cools the grinding wheel 21 and the workpiece during processing. The cleaning component 7 cleans the surface of the water baffle 26 after processing.

[0049] like Figures 1-4 and Figure 7 As shown, the control component 3 includes a control cabinet 31, a touch control panel 33, and a cooling fan 34;

[0050] A control cabinet 31 is mounted on the base plate 13. A touch control panel 33 is mounted on one side of the control cabinet 31. A cooling fan 34 is mounted on the side of the control cabinet 31 away from the touch control panel 33. The touch control panel 33 is electrically connected to the reducer 16 and the pneumatic push rod 15. When the workpiece is being ground, the corresponding pre-grinding program can be selected through the touch control panel 33 to control the grinding time, accuracy and amount of grinding.

[0051] like Figures 3-5 As shown, the repair assembly 4 includes a fixed frame 41, a mounting plate 42, a slide rail 43, a moving block 44, a shelf 45, a stepper motor 46, a hollow rotating platform 47, a connecting seat 48, a lever 49, and a grinding wheel rod 410.

[0052] A mounting bracket 41 is installed on the inner wall of the outer casing 25. A mounting plate 42 is mounted on the mounting bracket 41. A slide rail 43 is mounted on the mounting plate 42. A moving block 44 is mounted on the slide rail 43. A shelf 45 is mounted on the moving block 44. A stepper motor 46 is mounted on the shelf 45. A hollow rotary platform 47 is mounted on the output shaft of the stepper motor 46. A connecting seat 48 is installed at the bottom of the hollow rotary platform 47. A lever 49 is mounted on the connecting seat 48. A grinding wheel rod 410 is mounted at the end of the lever 49. The grinding wheel rod 410 is perpendicular to the lever 49. A water baffle plate 26 has an opening... There is an arc-shaped hole 262 through which the grinding wheel rod 410 passes. The stepper motor 46 is electrically connected to the touch control panel 33. When the grinding effect of the grinding wheel 21 deteriorates, the position of the moving block 44 on the slide rail 43 is controlled to put the stepper motor 46 into the working position. At this time, the stepper motor 46 drives the lever 49 on the hollow rotating platform 47 to rotate in an arc, thereby driving the grinding wheel rod 410, which is perpendicular to the lever 49, to dress the grinding wheel 21. This reduces the time required to remove the grinding wheel 21 for repair and reinstallation, thus achieving the effect of reducing maintenance time and saving manpower.

[0053] like Figures 1-7 As shown, the protective component 5 includes a rotating bracket 51, a pen-type push rod 52, a lower swing arm 53, an upper swing arm 54, and a protective cover 55;

[0054] A rotating bracket 51 is mounted on the base plate 13. A lower swing arm 53 and an upper swing arm 54 are rotatably mounted on the rotating bracket 51, and the upper swing arm 54 and the lower swing arm 53 are parallel to each other. A pen-type push rod 52 is rotatably mounted on the top of the rotating bracket 51. The other end of the pen-type push rod 52 is rotatably connected to the end of the lower swing arm 53 through a cylindrical pin. A protective cover 55 is mounted on the lower swing arm 53 and the upper swing arm 54, and the protective cover 55 is in contact with the outer shell 25. The pen-type push rod 52 is electrically connected to the touch control panel 33. When the equipment starts processing, the pen-type push rod 52 drives the upper swing arm 54 and the lower swing arm 53 to rotate downward, moving the protective cover 55 to the working position, thereby isolating and protecting the environment from metal chips and dust generated during grinding.

[0055] like Figures 3-7 As shown, the cooling assembly 6 includes a water tank 61, a return water inlet 611, a water pump 62, a float valve 63, a filter frame 64, a ball valve 65, and a collection frame 66;

[0056] A water tank 61 is placed inside the frame base 11. Four casters 12 and two ball valves 65 are installed at the bottom of the water tank 61. A return water inlet 611 is opened at the top of the water tank 61, and a filter frame 64 is installed inside the return water inlet 611. A float valve 63 is installed on the side wall of the return water inlet 611 near the top. A water pump 62 is installed at the top of the water tank 61. A fixing hole 264 is opened on the water baffle 26. The output end of the water pump 62 is connected to the fixing hole 264 through a cooling water pipe. A collection frame 66 is installed at the bottom. The output end of the collection frame 66 is connected to the return water port 611 through a return pipe. When the workpiece is being ground, the water pump 62 is started, and the water in the water tank 61 flows through the cooling pipe to the surface of the grinding wheel 21 to cool it down and remove the metal powder on the surface of the grinding wheel 21, thereby improving the grinding effect. After grinding, the water enters the return water port 611 through the return pipe on the collection frame 66, and after being filtered by the filter frame 64, it re-enters the water tank 61, thus realizing the recycling of water resources.

[0057] like Figure 1 , Figure 9 and Figures 3-7 As shown, the cleaning assembly 7 includes a first electric slide rail 71, a movable nozzle 72, a water inlet 721, a second electric slide rail 73, a slider 74, an electric push rod 75, a base plate 76, a telescopic rod 77, a cleaning rod 78, a cylindrical brush 79, a soft brush 710, a lifting rod 711, a support rod 712, an L-shaped fixing plate 713, a cleaning plate 714, a square hole 7141, and a cleaning wheel 7142.

[0058] A first electric slide rail 71 is installed on the side of the water baffle 26 away from the control cabinet 31. A movable nozzle 72 is slidably mounted on the first electric slide rail 71. A water inlet 721 is opened on the top of the movable nozzle 72. The water inlet 721 is connected to the water pump 62 through a cleaning water pipe. A solenoid valve is installed on the cleaning water pipe. A second electric slide rail 73 is installed on the side of the water baffle 26 closer to the control cabinet 31. A slider 74 is slidably mounted on the second electric slide rail 73. An electric push rod 75 is mounted on the slider 74. A base plate 7 is installed at the end of the electric push rod 75. 6. Multiple telescopic rods 77 are installed on the base plate 76. A cleaning rod 78 is vertically installed on the telescopic rod 77. A cylindrical brush 79 is rotatably installed on the cleaning rod 78. A soft brush 710 is installed at the bottom of the cleaning rod 78. A lifting rod 711 is installed on the second electric slide rail 73. A support rod 712 is installed on the lifting rod 711. An L-shaped fixing plate 713 is installed at the end of the support rod 712. Multiple cleaning plates 714 are installed on the L-shaped fixing plate 713. Multiple square holes 7141 are opened on the multiple cleaning plates 7141. Each of the multiple square holes 7141 contains... The cleaning wheel 7142 is rotatably mounted. The second electric slide rail 73 is electrically connected to the electric push rod 75. After the workpiece is processed, the solenoid valve opens, and the water pump 62 delivers water to the moving nozzle 72 through the cleaning water pipe. At the same time, the first electric slide rail 71 drives the moving nozzle 72 to spray water onto the baffle plate 26 as it moves. After rinsing, the second electric slide rail 73 drives the slider 74 to move intermittently to the other end. During the stop period, the electric push rod 75 drives the telescopic rod 77 to move, which in turn drives the cylindrical brush 7 on the cleaning rod 78. 9 and soft brush 710 move back and forth with electric push rod 75. When electric push rod 75 completes cleaning once and returns to the initial position, slider 74 returns to the initial position after cleaning. At this time, lifting rod 711 drives L-shaped fixed plate 713 to descend, so that cleaning plate 714 on L-shaped fixed plate 713 is between adjacent cylindrical brush 79. At this time, by moving electric push rod 75 back and forth, cylindrical brush 79 and cleaning wheel 7142 rotate relative to each other to squeeze and clean. Then, through rinsing and reciprocating cleaning, the water baffle cover 26 is fully and automatically cleaned.

[0059] The slider 74 moves intermittently on the second electric slide rail 73, and the interval time is the duration of one reciprocating motion of the electric push rod 75.

[0060] Working principle of the invention:

[0061] After the workpiece to be ground is clamped onto the clamping member 18, the pneumatic push rod 15 drives the reducer 16 on the guide post box 141 to descend. When the workpiece contacts the surface of the grinding wheel 21, the guide post box 141 stops descending. At this time, the reducer 16 drives the clamping member 18 to rotate, and at the same time, the drive motor 24 drives the small pulley 23 to rotate. The small pulley 23 drives the large pulley 22 to rotate through the belt, thereby causing the grinding wheel 21 on the rotating shaft 20 to rotate. Through the clamping member 18, multiple workpieces to be ground are rotated, so that each workpiece is in a position with the same grinding wheel linear velocity during grinding, so that multiple workpieces to be ground are ground to a uniform degree on the surface of the grinding wheel 21, ensuring that the processing accuracy of the same batch of workpieces is the same. When grinding, first press down on the protective disc 183. The protective disc 183 drives the sliding sleeve 182 to slide down on the connecting rod 181. When the annular groove 1824 descends to the position of the conical hole 1812, the ball 1813 in the conical hole 1812 loses pressure and rolls into the annular groove 1824, thus disengaging from the slot 1851. At this time, remove the mounting rod 185 on the central clamping disc 184 from the mounting hole 1811. Then, release the protective disc 183, and the spring 1822 drives the sliding sleeve 182 to reset. After the item to be ground is installed in the clamping hole 1841, install the mounting rod 185 into the mounting hole 1811, thereby achieving quick clamping of the item to be ground.

[0062] When grinding the workpiece, the corresponding pre-grinding program can be selected through the touch control panel 33 to control the grinding time, precision and amount of grinding.

[0063] When the grinding effect of the grinding wheel 21 deteriorates, the position of the control moving block 44 on the slide rail 43 is adjusted so that the stepper motor 46 is in the working position. At this time, the stepper motor 46 drives the lever 49 on the hollow rotating platform 47 to rotate in an arc, thereby driving the grinding wheel grinding rod 410, which is perpendicular to the lever 49, to dress the grinding wheel 21. This reduces the time required to remove the grinding wheel 21 for repair and reinstallation, thus achieving the effect of reducing maintenance time and saving manpower.

[0064] When the equipment starts processing, the pen-type push rod 52 drives the upper swing arm 54 and the lower swing arm 53 to rotate downwards, moving the protective cover 55 to the working position, thereby isolating and protecting the environment from metal chips and dust generated during grinding.

[0065] When the workpiece is being ground, the water pump 62 is started, and the water in the water tank 61 flows through the cooling pipe to the surface of the grinding wheel 21 to cool it down and remove the metal powder on the surface of the grinding wheel 21, thereby improving the grinding effect. After grinding, the water enters the return water port 611 through the return pipe on the collection frame 66, and after being filtered by the filter frame 64, it re-enters the water tank 61, thus realizing the recycling of water resources.

[0066] After the workpiece is processed, the solenoid valve opens, and the water pump 62 delivers water to the moving nozzle 72 through the cleaning water pipe. At the same time, the first electric slide rail 71 drives the moving nozzle 72 to spray water on the water baffle 26 as it moves. After rinsing, the second electric slide rail 73 drives the slider 74 to move intermittently to the other end. During the stop, the electric push rod 75 drives the telescopic rod 77 to move. The telescopic rod 77 drives the cylindrical brush 79 and soft brush 710 on the cleaning rod 78 to move back and forth with the electric push rod 75. When the electric push rod 75 completes one reciprocating movement and returns to the initial position, the slider 74 returns to the initial position after cleaning. At this time, the lifting rod 711 drives the L-shaped fixed plate 713 to descend, so that the cleaning plate 714 on the L-shaped fixed plate 713 is between the adjacent cylindrical brushes 79. At this time, the electric push rod 75 moves back and forth, so that the cylindrical brushes 79 and the cleaning wheel 7142 rotate relative to each other to squeeze and clean. Thus, the water baffle 26 is fully and automatically cleaned through rinsing and reciprocating cleaning.
