DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but are not to be construed as limiting the present invention.

[0036] Example 1

[0037] See also Figure 1-3 The present invention provides a technical solution: a blade grinding device for coating tool processing, comprising a bed 1, which is the installation base of the entire device. A trapezoidal groove is provided on the top of the bed 1. A cover 2 is fixedly connected to the top of the bed 1 for isolating the internal mechanism of the device from the external environment, reducing the interference of the external environment on grinding, and preventing debris generated during grinding from polluting the external environment. A rectangular through-hole is connected to the front of the cover 2, and a rectangular through-hole is connected to the top of the cover 2. A turntable 3 is rotatably connected to the top of the bed 1 for realizing the movement of the tool base. The trapezoidal groove on the top of the bed 1 is located on the back of the turntable 3, and a ventilation component 4 is fixedly connected to the top of the cover 2. It is used to inhale and divert external air to achieve cleaning of the tool base surface before and after grinding. The ventilation component 4 is located on the top of the turntable 3. The ventilation component 4 includes a diverter box 41. The diverter box 41 includes a box body 411. The bottom of the box body 411 is fixedly connected to the top of the top support plate 35. The bottom of the box body 411 is connected to a flare 412 for guiding the gas to blow toward the tool base surface. There are two flares 412, one of which is located on the front side of the top support plate 35, and the other is located on the back side of the top support plate 35. The top of the box body 411 is connected to an air inlet box 42, and the left side of the air inlet box 42 is connected to a blower. The blower is electrically connected to the electric control cabinet 7 through a wire.

[0038] A clamping assembly 5 is fixedly connected to the top of the turntable 3 for fixing the tool base of the blade to be sharpened. A grinding assembly 6 is slidably connected to the top of the cover 2. The grinding assembly 6 is located on the back of the turntable 3. The bottom of the grinding assembly 6 is slidably connected to the trapezoidal groove of the bed 1. The turntable 3, the clamping assembly 5, and the grinding assembly 6 are all located inside the cover 2. An electric control cabinet 7 is fixedly connected to the front of the bed 1. A PLC controller is installed inside the electric control cabinet 7 for controlling other mechanisms of the equipment.

[0039] When in use, the clamping assembly 5 is started by the electric control cabinet 7. Before the start of grinding, the tool is placed on the clamping assembly 5 with the blade facing outward and secured. After securing, the turntable 3, the ventilation assembly 4, and the grinding assembly 6 are started by the electric control cabinet 7. The tool base moves to the front of the grinding assembly 6 under the rotation of the turntable 3 and the clamping action of the clamping assembly 5. When the tool moves to the front of the grinding assembly 6, the grinding assembly 6 is started under the control of the electric control cabinet 7. At the same time, the clamping assembly 5 slides under the control of the electric control cabinet 7. The clamping assembly 5 and the grinding assembly 6 cooperate to grind the blade. The ground tool base rotates back to the front of the turntable 3 driven by the turntable 3. Then the staff checks the grinding condition of the blade and replaces the grinding surface to continue grinding. When all the blade surfaces are polished, the tool is taken out of the equipment.

[0040] During the grinding process, the electric control cabinet 7 controls the blower of the ventilation component 4 to start, and the blower draws external cold air into the air inlet box 42. The cold air enters the box body 411 through the air inlet box 42, and is finally diverted and guided by the expansion port 412 to be blown to the surface of the tool blade clamped by the clamping component 5. When the tool blade is being ground by the grinding component 6, the debris generated on its surface during the grinding process is cleared away by the high-speed airflow, preventing the debris from affecting the grinding process, and further preventing the debris from affecting the flatness of the grinding surface. At the same time, a part of the heat generated during the grinding process is transferred by the high-speed airflow, thereby achieving the cooling of the tool blade surface, thereby preventing the blade from being affected by excessive temperature and affecting its physical properties. The tool blade clamped by the clamping component 5 at one end away from the grinding component 6 is cleaned of residual debris on the surface under the action of the high-speed airflow, while accelerating the cooling of the blade surface, thereby improving production efficiency.

[0043] The bottom of the rotating bracket 31 is fixedly connected to a driving motor 37, which is a servo motor for driving the rotating bracket 31 to rotate so as to realize the mobile processing of the turntable 3 and the tool base. The driving motor 37 is electrically connected to the electric control cabinet 7 through a wire. The top of the rotating bracket 31 is fixedly connected to a hollow buffer block 32. The top of the hollow buffer block 32 is provided with a hexagonal through hole for absorbing the vibration of the turntable 3 when the equipment is running, so as to prevent the vibration from loosening the clamping assembly 5 on the tool and reducing the grinding accuracy of the blade. The top of the bed 1 is fixedly connected to a supporting base plate 33, which supports The top of the bottom plate 33 is rotatably connected to a lateral guard plate 34. The inner surface of the lateral guard plate 34 is fixedly connected to the outer surface of the rotating bracket 31 to limit the lateral movement of the hollow buffer block 32. The top of the supporting bottom plate 33 is fixedly connected to a top support plate 35. The lateral guard plate 34 is located at the bottom of the top support plate 35. The bottom of the top support plate 35 is fixedly connected to a top cleaning plate 36. The bottom of the cleaning plate 36 is fixedly connected to a nylon soft brush for scraping impurities on the surface of the tool base before and after grinding. There are two top cleaning plates 36, which are symmetrically distributed on both sides of the rotating bracket 31.

[0044] The clamping assembly 5 comprises:

[0045] The bottom clamping plate 51 is slidably connected to the top of the turntable 3. The back of the bottom clamping plate 51 is fixedly connected to a metal plate, which is the installation base of the entire clamping assembly 5. The bottom clamping plate 51 includes a bottom plate body 511. The bottom of the bottom plate body 511 is slidably connected to the top of the horizontal bracket 312. The left side cross-section of the bottom plate body 511 is L-shaped. The top of the bottom plate of the bottom plate body 511 is fixedly connected to a copper pad for reducing wear during clamping. The top of the bottom plate body 511 is fixedly connected to an electromagnet assembly 512. The electromagnet assembly 512 includes an electromagnetic coil. The electromagnet assembly 512 is electrically connected to the electric control cabinet 7 through a wire.

[0046] The top clamping plate 52 is slidably connected to the top of the bottom clamping plate 51 and is used to cooperate with the bottom clamping plate 51 to clamp the tool base. The top clamping plate 52 includes a top plate body 521. The top of the top plate body 521 is fixedly connected to a slide rod 522. The surface of the slide rod 522 is slidably connected to the inside of the electromagnet assembly 512. The top of the electromagnet assembly 512 is fixedly connected to the top of the slide rod 522 through a spring. A pressure sensor is fixedly connected to the top of the top plate body 521 for sensing the pressure of clamping the tool. The pressure sensor is electrically connected to the electric control cabinet 7 through a wire.

[0047] The electric push rod 53 is fixedly connected to the top of the turntable 3. The left side of the electric push rod 53 is fixedly connected to the right side of the metal plate on the back of the bottom clamp 51. The electric push rod 53 is electrically connected to the electric control cabinet 7 through a wire to realize the sliding of the bottom clamp 51. The electric push rod 53 is located on the back of the bottom plate body 511. There are two clamping assemblies 5, and the other one is slidably connected to the top of the horizontal bracket 312 on the back.

[0048] When in use, before grinding, the tool base is placed on the top of the copper pad of the bottom plate body 511 to ensure that the blade of the tool is located outside the bottom plate body 511 and is not clamped and covered by the top clamping plate 52. After it is placed firmly, the electromagnet assembly 512 is controlled by the electric control cabinet 7 to start. After the electromagnet assembly 512 is started, an electromagnetic force is generated to drive the slide rod 522 to drive the top plate body 521 to slide downward, and finally complete the clamping of the tool base together with the bottom plate body 511;

[0049] After the clamping is stable, the electric control cabinet 7 controls the drive motor 37 to start, and the drive motor 37 drives the rotating bracket 31 to rotate clockwise. The clamping assembly 5 rotates together with the rotating bracket 31. When the blade rotates through the top cleaning plate 36 on the left, the upper surface of the blade is scraped by the nylon brush to remove the fine solid impurities that may exist on its surface to prevent it from being polished. When the clamping assembly 5 rotates to the position in front of the polishing assembly 6, the drive motor 37 stops rotating, and then the polishing assembly 6 starts to polish the blade. During the polishing process, the electric The push rod 53 is adjusted and formed under the control of the electric control cabinet 7, thereby driving the bottom clamping plate 51 and the top clamping plate 52 to slide left and right, thereby adjusting the grinding position of the blade. During the grinding process, the pressure sensor of the top plate body 521 monitors the pressure value on the surface of the tool base in real time, and then adjusts the electromagnetic force of the electromagnet assembly 512, thereby adjusting the clamping force of the tool base. After the grinding is completed, the polished tool is driven by the rotating bracket 31 to pass through the top cleaning plate 36 on the right side to clean the polished blade surface for subsequent inspection.

[0050] During the rotation of the turntable 3, the hollow buffer block 32 absorbs the vibration during the rotation process through the internal hexagonal hollow structure. At the same time, it absorbs the vibration generated when the grinding assembly 6 grinds the blade during the grinding process, preventing the vibration from loosening the clamping of the bottom clamp 51 and the top clamp 52 on the tool base.

[0051] Example 3

[0052] See also Figure 1-8 On the basis of the first and second embodiments, the present invention provides a technical solution: the grinding assembly 6 includes a slide 61, the bottom of the slide 61 is slidably connected to the inside of the trapezoidal groove on the top of the bed 1, the back of the slide 61 is fixedly connected to a pulley frame 62, the top of the pulley frame 62 is fixedly connected to a servo motor, the servo motor is electrically connected to the electric control cabinet 7 through a wire, and the left side of the servo motor is fixedly connected to a sliding wheel 63 for driving the slide 61 to move back and forth;

[0053] A grinding wheel sleeve 64 is fixedly connected to the top of the slide 61, which is used to limit the vertical movement of the grinding wheel 65 and thus reduce the grinding deviation of the blade. The grinding wheel sleeve 64 is rotatably connected to the inside of the grinding wheel sleeve 64 for grinding the blade. A DC motor is fixedly connected to the top of the grinding wheel sleeve 64, and the DC motor is electrically connected to the electric control cabinet 7 through a wire. The motor shaft of the grinding wheel 65 is fixedly connected to the grinding wheel sleeve 64. A sensor bracket 66 is fixedly connected to the top of the grinding wheel sleeve 64, and the sensor bracket 66 includes a distance sensor for sensing the distance between the grinding component 6 and the blade. The distance sensor is electrically connected to the electric control cabinet 7 through a wire, and the distance sensor is located on the front of the DC motor.

[0054] During use, when the tool to be polished rotates to the front of the slide 61, the servo motor on the top of the pulley frame 62 is started under the control of the electric control cabinet 7, thereby driving the sliding wheel 63 to rotate. The rotation of the sliding wheel 63 drives the slide 61 to slide and adjust its position. At the same time, the distance sensor on the sensor bracket 66 monitors its distance to the bottom in real time. When the sensor bracket 66 detects that the distance data suddenly drops, the electric control cabinet 7 controls the motor on the top of the grinding wheel sleeve 64 to start, and the motor drives the grinding wheel 65 to rotate, and polishes the blade of the tool with the cooperation of the clamping assembly 5. At the same time, during the polishing process, the distance sensor feeds back the distance data to the blade position to the electric control cabinet 7 in real time, so that the electric control cabinet 7 can judge the vibration of the blade surface, and then adjust the rotation speed of the grinding wheel 65 to reduce the influence of vibration on the grinding accuracy of the blade surface.
