Description
Technical Field
[0001] This invention relates to the field of diamond blade grinding technology, specifically to a medical diamond blade edge grinding device. Background Technology
[0002] Medical diamond blades are characterized by high hardness, small cutting edge size, and high precision requirements for cutting edge processing. During their processing, grinding equipment is usually used to grind the blade edge step by step, and different cutting edges are processed according to the target cutting edge shape of the blade. Especially for medical diamond blades with double cutting edges, after grinding one cutting edge, the processing posture of the blade needs to be adjusted to continue grinding the other cutting edge. In some existing blade grinding equipment, the blades are usually in contact with the grinding disc in a relatively fixed posture through a clamping structure. When it is necessary to switch to different cutting edges for grinding, the position and angle of the blades relative to the grinding disc need to be readjusted. At the same time, the contact between the blades and the grinding disc is easily affected by factors such as slight changes in the height of the grinding disc surface, blade clamping errors, and the gradual removal of cutting edge material. For medical diamond blades with small thickness and gradually thinning cutting edges, if the grinding contact cannot be adaptively adjusted according to the processing stage, it is easy to cause large changes in local grinding action, increasing the possibility of over-grinding of the cutting edge and chipping. Summary of the Invention
[0003] To address the shortcomings of existing technologies, such as the need to readjust the position and angle of the blade relative to the grinding disc when switching between different cutting surfaces for grinding, and the susceptibility of the contact between the blade and the grinding disc to minor changes in the surface height of the grinding disc, blade clamping errors, and the gradual removal of cutting surface material, this invention provides a medical diamond blade edge grinding device.

[0005] As a preferred embodiment of the present invention, the reciprocating drive assembly includes a reciprocating turntable rotatably connected to the upper surface of the base. A limiting post is fixedly connected to one side of the upper surface of the reciprocating turntable. A reciprocating frame is fixedly connected to the lower surface of the reciprocating slide. A limiting groove adapted to the limiting post is provided on the reciprocating frame. The extending direction of the limiting groove is perpendicular to the extending direction of the guide rail. A reciprocating motor for driving the reciprocating turntable to rotate is fixedly connected to the side of the lower surface of the base near the reciprocating turntable.
[0006] As a preferred embodiment of the present invention, the pressure regulating assembly includes an regulating groove formed on the upper surface of the support frame, a wedge-shaped regulating block slidably connected in the regulating groove, an regulating threaded hole formed on one side of the outer wall of the wedge-shaped regulating block, an regulating screw threadedly connected in the regulating threaded hole, the regulating screw rotatably connected to the support frame, and one end of the regulating screw passing through the support frame and fixedly connected to an regulating handwheel, a support plate slidably connected on the guide rod below the floating seat, a lifting roller rotatably connected to the lower surface of the support plate near the wedge-shaped regulating block, and a support spring fixedly connected to the upper surface of the support plate, the top ends of the support springs being fixedly connected to the floating seat.
[0007] As a preferred embodiment of the present invention, guide holes adapted to the guide rods are provided at the four corners of the floating seat and the support plate, and limit blocks are fixedly connected to the top of the guide rods.
[0008] As a preferred embodiment of the present invention, both sides of the outer side wall of the flipping frame are fixedly connected to a flipping shaft that is rotatably connected to the inner side wall of the adjustment box.
[0009] As a preferred embodiment of the present invention, both sides of the outer wall of the adjustment box are provided with arc-shaped adjustment grooves, the center of the arc-shaped adjustment grooves is located on the axis of the flipping shaft, and a positioning threaded hole is provided on the side of the outer wall of the flipping frame near the arc-shaped adjustment groove, and a positioning bolt is threaded into the positioning threaded hole.
[0010] As a preferred embodiment of the present invention, an indicator needle that is slidably connected to the side of the outer wall of the flipping frame away from the positioning threaded hole is fixedly connected, and an angle scale is embedded in the side of the outer wall of the adjustment box near the indicator needle.
[0011] As a preferred embodiment of the present invention, the blade clamping assembly includes a clamping seat fixedly connected to the inner wall of the flipping frame. A clamping threaded hole is provided on one side of the outer wall of the clamping seat. A clamping bolt is threadedly connected to the clamping threaded hole. A clamping pad is rotatably connected to one end of the clamping bolt located inside the clamping seat.
[0012] In summary, this application has the following beneficial effects: 1. This invention, through the arrangement of a guide rod, a floating seat, a pressure adjustment component, a suspension, an adjustment box, a flipping frame, and a blade clamping component, allows the blade to adjust the grinding posture of different cutting surfaces relative to the grinding disc during a single clamping state via the flipping frame. Simultaneously, the pressure adjustment component alters the upward support of the floating seat, enabling the blade to form corresponding grinding contact states according to different grinding stages. Furthermore, the floating seat allows for small-range up-and-down movement along the guide rod during normal grinding, providing elastic compensation for minor height changes on the grinding disc surface, blade clamping errors, and contact changes caused by material removal from the cutting surface. This reduces the possibility of excessive grinding and chipping of the cutting edge due to excessive local grinding variations. 2. This invention, through the arrangement of an adjusting groove, a wedge-shaped adjusting block, an adjusting screw, an adjusting handwheel, a support plate, a lifting roller, and a support spring, allows the wedge-shaped adjusting block to move by rotating the adjusting handwheel. The position of the support plate is changed by utilizing the inclined upper surface of the wedge-shaped adjusting block and the cooperation of the lifting roller, thereby adjusting the support spring's support effect on the floating seat. At the same time, when it is necessary to switch the blade cutting surface, the position of the support plate can be further raised, causing the floating seat and the blade as a whole to move upward and detach from the grinding disc, creating clearance space for the angle switching of the flipping frame, eliminating the need for a separate blade retraction mechanism. 3. By setting up a guide rail, a reciprocating slide, a reciprocating turntable, a limiting post, a reciprocating frame, and a limiting groove, the continuous rotation of the reciprocating turntable can be converted into the reciprocating linear motion of the reciprocating slide along the guide rail. This allows the blade to move back and forth along the working area of the grinding disc during the grinding process, avoiding the blade from continuously acting on the same position of the grinding disc. This disperses the local wear of the grinding disc and allows different positions of the blade edge to be repeatedly processed by the grinding disc. Attached Figure Description

[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0016] Example: Please refer to Figure 1 , Figure 2 and Figure 3The present invention discloses a medical diamond blade edge grinding device, comprising a base 1, a grinding spindle 2 rotatably connected to one side of the upper surface of the base 1, a grinding disc 3 fixedly connected to the top end of the grinding spindle 2, and a grinding motor 4 for driving the grinding spindle 2 to rotate fixedly connected to the lower surface of the base 1. The grinding spindle 2 is rotatably supported on the base 1 through a bearing structure. The output end of the grinding motor 4 is connected to the bottom end of the grinding spindle 2. When the grinding motor 4 is running, the grinding disc 3 can be continuously rotated through the grinding spindle 2, so that the upper surface of the grinding disc 3 can grind the medical diamond blade. The grinding disc 3 can be selected according to the material of the medical diamond blade to be processed and the grinding stage. For example, when the blade blank is initially shaped and the allowable material needs to be removed quickly, a metal-bonded diamond grinding disc and a grinding disc with relatively coarse diamond abrasive grains on the surface can be used to give it a high material removal capacity. When the blade surface has been basically formed and the fine grinding stage has begun, a cast iron grinding disc with a smoother surface can be used, and a finer diamond abrasive grain can be added to its working surface to reduce the amount of material removed per pass and improve the surface quality of the blade. In the fine grinding stage that is closer to the final cutting edge, submicron and finer diamond abrasive grains can be used to reduce the possibility of local chipping when coarser abrasive grains directly act on the already formed fine cutting edge. Therefore, the same equipment can be adapted to different processing stages such as coarse grinding, fine grinding and cutting edge finishing by changing the grinding disc 3 and the grinding media on its surface.
[0017] Reference Figure 2 , Figure 3 and Figure 4 Guide rails 5 are fixedly connected to both sides of the upper surface of the base 1. A reciprocating slide 6 is slidably connected to the guide rails 5. A reciprocating drive assembly 7 is provided on the base 1 for driving the reciprocating slide 6 to move back and forth along the guide rails 5. The reciprocating drive assembly 7 includes a reciprocating turntable 71 rotatably connected to the upper surface of the base 1. A limit post 72 is fixedly connected to one side of the upper surface of the reciprocating turntable 71. A reciprocating frame 73 is fixedly connected to the lower surface of the reciprocating slide 6. A limit groove 74 adapted to the limit post 72 is opened on the reciprocating frame 73. The extension direction of the limit groove 74 is perpendicular to the extension direction of the guide rails 5. A reciprocating motor 75 for driving the reciprocating turntable 71 to rotate is fixedly connected to the side of the lower surface of the base 1 near the reciprocating turntable 71. The output end of the reciprocating motor 75 passes through the base 1 and is fixedly connected to the reciprocating turntable 71. The limiting post 72 is set off from the rotation center of the reciprocating turntable 71. When the reciprocating motor 75 drives the reciprocating turntable 71 to rotate, the limiting post 72 makes a circular motion with the rotation center of the reciprocating turntable 71 as the center. Since the reciprocating slide 6 is guided and restricted by the guide rails 5 on both sides, it can only move along the extension direction of the guide rails 5. The displacement generated by the limiting post 72 along the direction of the guide rails 5 is transmitted to the reciprocating slide 6 through the reciprocating frame 73, thereby converting the continuous rotation of the reciprocating turntable 71 into the reciprocating linear motion of the reciprocating slide 6 along the guide rails 5. This avoids the blade from continuously acting on the same annular position of the grinding disc 3. On the one hand, it allows the blade edge to repeatedly pass through the grinding disc 3 at different positions, and on the other hand, it can disperse the local wear of the grinding disc 3.
[0018] Reference Figure 4 , Figure 5 and Figure 6 A support frame 8 is fixedly connected to the reciprocating slide 6. Guide rods 9 are fixedly connected to the four corners of the upper surface of the support frame 8. A floating seat 10 is slidably connected to the guide rods 9. A pressure adjustment assembly 11 for supporting the floating seat 10 is provided on the upper surface of the support frame 8. The pressure adjustment assembly 11 includes an adjustment groove 111 opened on the upper surface of the support frame 8. A wedge-shaped adjustment block 112 is slidably connected in the adjustment groove 111. An adjustment threaded hole 113 is opened on one side of the outer wall of the wedge-shaped adjustment block 112. An adjustment screw 114 is threadedly connected in the adjustment threaded hole 113. The adjustment screw 114 is rotatably connected to the support frame 8.
[0019] Reference Figure 5 , Figure 6 and Figure 7 One end of the adjusting screw 114 passes through the support frame 8 and is fixedly connected to the adjusting handwheel 115. A support plate 116 is slidably connected to the guide rod 9 below the floating seat 10. Guide holes 16 that are adapted to the guide rod 9 are opened at the four corners of the floating seat 10 and the support plate 116. Limiting blocks 17 are fixedly connected to the top of the guide rod 9. The floating seat 10 and the support plate 116 are slidably connected to the guide rod 9 through the guide holes 16. The limiting blocks 17 are used to limit the maximum position of the floating seat 10 moving upward along the guide rod 9 and to prevent the floating seat 10 from detaching from the top of the guide rod 9. A lifting roller 117 is rotatably connected to the lower surface of the support plate 116 near the wedge-shaped adjusting block 112, and a support spring 118 is fixedly connected to the upper surface of the support plate 116. The top of the support spring 118 is fixedly connected to the floating seat 10. The bottom of the wedge-shaped adjusting block 112 is adapted to the adjusting groove 111, so that the wedge-shaped adjusting block 112 can move linearly along the extension direction of the adjusting groove 111. At the same time, the adjusting groove 111 restricts the wedge-shaped adjusting block 112 from producing obvious lateral displacement. The upper surface of the wedge-shaped adjusting block 112 is set as an inclined surface, and the outer peripheral surface of the lifting roller 117 abuts against the inclined upper surface of the wedge-shaped adjusting block 112. The inclined upper surface forms a height change along the moving direction of the wedge-shaped adjusting block 112, so that when the wedge-shaped adjusting block 112 moves along the adjusting groove 111, the lifting roller 117 can move up and down accordingly with the height change of its contact position. Under normal grinding conditions, the support spring 118 provides upward elastic support to the floating seat 10. Its upward support is less than the downward force formed by the floating seat 10 and the structure above it, so that the blade can maintain grinding contact with the grinding disc 3. At the same time, the floating seat 10 is not rigidly fixed. When there is a slight change in the height of the working surface of the grinding disc 3, a slight error in the blade clamping position, or a change in the contact state of the blade edge as the material is removed, the floating seat 10 can move up and down along the guide rod 9 accordingly. The elastic deformation of the support spring 118 buffers and compensates for the changes in contact between the blade and the grinding disc 3. The operator can rotate the adjusting handwheel 115 to drive the adjusting screw 114 to rotate, which in turn drives the wedge-shaped adjusting block 112 to move linearly along the adjusting groove 111. During this process, the lifting roller 117 rolls along the inclined upper surface of the wedge-shaped adjusting block 112, and further drives the support plate 116 to move up and down along the guide rod 9. Therefore, the contact state between the blade and the grinding disc 3 can be changed according to different blades and different grinding stages. For example, when performing preliminary cutting surface shaping on a diamond blade blank with a relatively large thickness and a lot of machining allowance, the position of the support plate 116 can be appropriately lowered to reduce the compression degree of the support spring 118 and its upward support effect on the floating seat 10, so that the blade forms a relatively large grinding effect to improve the cutting surface shaping efficiency. When the cutting surface has been basically shaped and begins to approach the final cutting edge, the position of the support plate 116 can be raised to gradually increase the compression degree of the support spring 118 and the upward support effect, thereby reducing the actual grinding pressure. When performing fine finishing on thin ophthalmic diamond blades and blades that have already formed a fine cutting edge, a greater upward support effect can be used to make the blade cooperate with the grinding disc 3 in a lighter contact state, thereby reducing the possibility of chipping, cracking and local over-grinding when a large mechanical load is applied to thin blades or fine cutting edges. For single-crystal diamond cutting tools, the grinding pressure can be selected based on the specific crystal orientation and the actual grinding conditions. When a certain cutting surface is in a relatively easy grinding direction, a lighter grinding action can be used to complete the fine dressing. When the material removal is slow and the grinding vibration is relatively obvious, the material removal can be adjusted by changing the grinding media and adjusting the contact pressure, rather than simply increasing the removal amount by continuously increasing the pressure. The pressure adjustment component 11 can also be used for vertical clearance when the blade face is switched. After a blade face to be processed is ground, the adjustment handwheel 115 can be rotated in the direction that raises the support plate 116, so that the relatively high position of the upper surface of the wedge adjustment block 112 is further moved to below the lifting roller 117. The lifting roller 117 drives the support plate 116 to continue to move upward along the guide rod 9, further increasing the compression degree of the support spring 118 and the upward support effect. When the upward action formed by the support spring 118 can push the floating seat 10 to move upward, the floating seat 10 moves upward along the guide rod 9, and simultaneously drives the structure above it and the blade after clamping to move upward, so that the blade is separated from the working surface of the grinding disc 3 and forms a clearance gap for the blade to switch blade faces. The adjustment groove 111, wedge-shaped adjustment block 112, guide rod 9 and floating seat 10 are provided with an effective movement stroke to meet the above-mentioned pressure adjustment and face-changing avoidance. When the pressure adjustment component 11 is in the normal grinding adjustment range, the grinding contact state of the blade is mainly adjusted by changing the compression degree of the support spring 118. When the adjustment is continued to the face-changing avoidance position, the floating seat 10 can be moved upward as a whole to the position where the blade and the grinding disc 3 are separated. After the blade has completed the face switching, the adjusting handwheel 115 can be rotated in the opposite direction to move the wedge adjusting block 112 in the opposite direction and gradually lower the position of the lifting roller 117 and the support plate 116. This gradually reduces the upward supporting effect of the support spring 118 on the floating seat 10, and the floating seat 10 and the structure above it move downward. This allows the blade to be processed after the face switching to gradually approach the grinding disc 3 and re-establish the corresponding grinding contact state. In this way, the blade can gradually restore contact after the face switching without having to keep the blade in direct contact with the grinding disc 3 during the flipping process.
[0020] Reference Figure 1 , Figure 3 and Figure 4 A suspension 12 is fixedly connected to the floating seat 10. An adjustment box 13 is fixedly connected to one end of the suspension 12. A flipping frame 14 is rotatably connected to the inner wall of the adjustment box 13. A flipping shaft 18, which is rotatably connected to the inner wall of the adjustment box 13, is fixedly connected to both sides of the outer wall of the flipping frame 14.
[0021] Reference Figure 3 , Figure 4 and Figure 8Both sides of the outer wall of the adjustment box 13 are provided with arc-shaped adjustment grooves 19. The center of the arc-shaped adjustment grooves 19 is located on the axis of the flipping shaft 18. The outer wall of the flipping frame 14 is provided with a positioning threaded hole 20 on the side near the arc-shaped adjustment grooves 19. The positioning threaded hole 20 is internally threaded with a positioning bolt 21. The positioning bolt 21 passes through the corresponding arc-shaped adjustment groove 19 from the outside of the adjustment box 13 and is threaded into the positioning threaded hole 20. The head of the positioning bolt 21 is located on the outside of the adjustment box 13. After the positioning bolt 21 is loosened, the flipping frame 14 can rotate relative to the adjustment box 13 with the axis of the flipping shaft 18 as the center. At the same time, the positioning bolt 21 moves along the arc-shaped adjustment groove 19. When the flipping frame 14 is adjusted to the required angle, the positioning bolt 21 is tightened so that the head of the positioning bolt 21 abuts against the outer wall of the adjustment box 13, thereby locking the flipping frame 14 at the current angle. An indicator needle 22 is fixedly connected to the side of the outer wall of the flipping frame 14 away from the positioning threaded hole 20 and slidably connected to the arc-shaped adjustment groove 19. An angle scale 23 is embedded in the side of the outer wall of the adjustment box 13 near the indicator needle 22. When the flipping frame 14 rotates around the flipping shaft 18, the indicator needle 22 moves synchronously with the flipping frame 14 along the arc-shaped adjustment groove 19 on the other side. The operator can observe the current rotation angle of the flipping frame 14 according to the corresponding position of the indicator needle 22 and the angle scale 23. The specific grinding angle can be set according to the target cutting edge of the medical diamond blade. For example, for a single bevel blade with a cutting edge only on one side, the corresponding cutting edge can be adjusted to form a target grinding angle relative to the grinding disc 3 and then the rotating frame 14 can be fixed to complete the processing of the single-sided cutting edge. For blades with two cutting edges, the first cutting edge can be made to form a first grinding angle first. After the first cutting edge is processed, the rotating frame 14 can be rotated to make the second cutting edge form a second grinding angle. For symmetrical double-edged blades, the first grinding angle and the second grinding angle can have the same angle value and be located on both sides of the blade reference plane. If the target cutting face of the blade is designed with the same tilt angle, the two cutting faces can be adjusted to form the same target angle relative to the grinding disc 3. For asymmetrical double-edged blades, the two grinding angles can be set separately. For example, the first cutting face can use a smaller tilt angle to form a wider cutting face, and the second cutting face can use a relatively larger tilt angle to form the other cutting face, thus obtaining an asymmetrical cutting edge. The design angle of the scalpel blade can be in the range of ten to several tens of degrees. For example, when processing a double-edged blade, the first blade is adjusted to a position of about 20° relative to the grinding disc 3 for grinding. After the first blade is completed, the flipping frame 14 is adjusted to the corresponding 20° position on the other side according to the geometric relationship of the designed second blade. If the blade being processed uses an asymmetrical blade, the first blade can be adjusted to 20° and the second blade to 30°, for example. The above angles are only used to illustrate that the equipment can adapt to different blade angles and do not constitute a limitation on the actual blade angle of the medical diamond blade. When machining a batch of cutting tools of the same specification, the angle scale corresponding to the first and second cutting surfaces can be recorded. After the subsequent cutting tools are clamped, the initial adjustment can be made directly according to the recorded angle, and then fine-tuned according to the actual contact state, thereby reducing the operation of completely re-finding the machining angle each time. A blade clamping assembly 15 is fixedly connected to the inner wall of the flipping frame 14. The blade clamping assembly 15 includes a clamping seat 151 fixedly connected to the inner wall of the flipping frame 14. A clamping threaded hole 152 is opened on one side of the outer wall of the clamping seat 151. A clamping bolt 153 is threaded into the clamping threaded hole 152. A clamping pad 154 is rotatably connected to one end of the clamping bolt 153 located inside the clamping seat 151. When in use, place the medical diamond blade to be processed into the clamping seat 151, then rotate the clamping bolt 153. The clamping bolt 153 moves along the clamping threaded hole 152 toward the blade and pushes the clamping pad 154 against the blade, so that the blade is clamped between the clamping pad 154 and the clamping seat 151. The clamping seat 151 can be configured with a corresponding support surface according to the shape of the cutting tool being processed. For example, for ophthalmic diamond cutting tools that are thin in shape, the clamping seat 151 can be configured to hold the cutting tool away from the base area of the cutting edge, so that the cutting edge to be processed extends outward from the clamping seat 151, thus avoiding the clamping action being directly applied to the already formed and soon-to-be-formed cutting edge position. For diamond cutting tool blanks with relatively large thickness, the stability during the processing can be improved by using a larger clamping contact area. The clamping pad 154 facing the blade can be provided with a copper sheet, a soft metal pad, an engineering plastic pad, or other protective layers with a hardness lower than that of the blade to be clamped, so that the clamping force can be transmitted in a larger contact area, reducing the possibility of the diamond blade being subjected to pressure from local hard points.
[0022] The implementation principle of this invention is as follows: During operation, the appropriate grinding disc 3 and grinding media are selected based on the material type, cutting surface structure, and current processing stage of the medical diamond blade to be processed. When the blade blank has a large machining allowance and requires preliminary cutting surface shaping, a grinding disc 3 and grinding media with relatively high material removal capacity can be used. When the blade cutting surface has been basically formed and has entered the fine grinding and cutting edge finishing stage, a grinding disc 3 with a smoother surface and a diamond grinding media with relatively finer particle size can be used to reduce the amount of material removed per pass and reduce the possibility of the already formed small cutting edge being subjected to a large grinding load and causing breakage. Before clamping the blade, keep the grinding motor 4 and reciprocating motor 75 stopped, and adjust the handwheel 115 to make the pressure regulating component 11 so that the floating seat 10 is relatively raised, so that the blade clamping component 15 and the grinding disc 3 maintain the corresponding operating space. Then, place the base of the medical diamond blade to be processed away from the cutting edge to be processed in the clamping seat 151, rotate the clamping bolt 153 so that the clamping bolt 153 moves along the clamping thread hole 152 towards the blade, and push the clamping pad 154 against the blade, thereby clamping the blade between the clamping pad 154 and the clamping seat 151, so that the cutting edge of the blade to be processed extends out of the clamping seat 151. After the blade is clamped, the grinding posture of the blade is adjusted according to the target blade shape of the first blade surface to be processed. The positioning bolt 21 is loosened so that the flipping frame 14 can rotate relative to the adjustment box 13 via the flipping shaft 18. During the rotation of the flipping frame 14, the positioning bolt 21 moves along the arc-shaped adjustment groove 19 on one side, and the indicator needle 22 moves synchronously with the flipping frame 14 along the arc-shaped adjustment groove 19 on the other side. The operator can observe the current angle of the flipping frame 14 through the corresponding position of the indicator needle 22 and the angle scale 23. When the first blade surface to be processed is adjusted to form the required grinding posture relative to the grinding disc 3, the positioning bolt 21 is tightened so that the head of the positioning bolt 21 presses against the outer wall of the adjustment box 13, thereby fixing the flipping frame 14 and the blade in the first processing position. After the angle of the first cutting edge to be processed is adjusted, the adjusting handwheel 115 is rotated. The adjusting handwheel 115 drives the adjusting screw 114 to rotate. The adjusting screw 114 drives the wedge-shaped adjusting block 112 to move along the adjusting groove 111 through the threaded engagement with the adjusting threaded hole 113. During the movement of the wedge-shaped adjusting block 112, the contact position between its inclined upper surface and the lifting roller 117 changes, causing the lifting roller 117 to move up and down accordingly, and driving the support plate 116 to move up and down along the guide rod 9. This changes the distance between the support plate 116 and the floating seat 10 and the degree of compression of the support spring 118, so that the support spring 118 forms different sizes of upward support for the floating seat 10. When the blade transitions from the avoidance state to the grinding state, the reverse adjustment pressure adjustment component 11 is adjusted to gradually lower the support plate 116. The upward support of the support spring 118 on the floating seat 10 is reduced accordingly. The floating seat 10, as well as the suspension 12, adjustment box 13, flipping frame 14, blade clamping component 15 and the blade fixed above it, can gradually move downward along the guide rod 9, so that the first cutting edge to be processed slowly approaches the grinding disc 3. After the first cutting edge to be processed establishes contact with the grinding disc 3, the adjustment handwheel 115 is finely adjusted according to the blade material, the condition of the cutting edge and the current grinding stage, so that the support spring 118 forms an appropriate upward support on the floating seat 10, thereby keeping the blade in the required grinding contact state. Under normal grinding conditions, the upward support formed by the support spring 118 is less than the downward support formed by the floating seat 10 and the structure above it, so that the blade can maintain continuous grinding contact with the grinding disc 3. At the same time, the floating seat 10 is not rigidly fixed. When there is a slight change in the height of the working surface of the grinding disc 3, a slight error in the blade clamping position, or a change in the contact state of the blade edge as the material is removed, the floating seat 10 can move up and down in a small range along the guide rod 9 through the guide hole 16, and buffer and compensate for the contact changes between the blade and the grinding disc 3 through the elastic deformation of the support spring 118, thereby reducing the possibility of a sudden increase in grinding load due to local height changes when in complete rigid contact. When the blade blank is initially shaped and has a large machining allowance, the support plate 116 can be placed in a relatively low position, so that the compression degree of the support spring 118 and the upward support effect on the floating seat 10 are relatively small, and the blade contacts the grinding disc 3 with a relatively large grinding action. When the blade surface gradually approaches the target shape and enters the fine grinding and edge finishing stage, the support plate 116 can be appropriately raised by adjusting the handwheel 115 to increase the compression degree of the support spring 118 and the upward support effect, thereby reducing the actual grinding pressure of the blade on the grinding disc 3, so that the already formed fine edge can be processed with a relatively light contact state. After adjusting the blade angle and grinding contact state, the grinding motor 4 is started. The grinding motor 4 drives the grinding spindle 2 to rotate, and the grinding spindle 2 drives the grinding disc 3 to rotate continuously, so that the grinding disc 3 forms a continuously moving grinding working surface. Then, the reciprocating motor 75 is started, and the reciprocating motor 75 drives the reciprocating turntable 71 to rotate. Since the limiting post 72 is set off from the rotation center of the reciprocating turntable 71, the limiting post 72 moves in a circle with the reciprocating turntable 71. The movement of the limiting post 72 in the direction perpendicular to the guide rail 5 is released by its relative sliding in the limiting groove 74. The movement of the limiting post 72 in the direction of the guide rail 5 is transmitted to the reciprocating slide 6 through the reciprocating frame 73, thereby converting the continuous rotational motion of the reciprocating turntable 71 into the reciprocating linear motion of the reciprocating slide 6 along the guide rail 5. When the reciprocating slide 6 moves back and forth along the guide rail 5, the support frame 8 and the guide rod 9, floating seat 10, suspension 12, adjustment box 13, flipping frame 14, blade clamping assembly 15 and the blade move back and forth synchronously, so that the first cutting edge of the blade passes back and forth along the working area of the grinding disc 3. The reciprocating movement of the blade and the continuous rotation of the grinding disc 3 together achieve the removal of material from the cutting edge. At the same time, it can prevent the blade from acting on the same annular position of the grinding disc 3 for a long time, so that different positions of the blade cutting edge repeatedly pass through the grinding disc 3, and disperse the local wear of the grinding disc 3. During the above grinding process, the floating seat 10 always maintains the vertical floating freedom along the guide rod 9. The supporting spring 118 bears part of the weight of the floating seat 10 and the structure above it, and adjusts the actual grinding action between the blade and the grinding disc 3. On the other hand, it can elastically compensate for minor disc surface errors, clamping errors and contact state changes during the reciprocating passage of the blade through the grinding disc 3. Therefore, the pressure adjustment component 11 does not limit the blade rigidity to a certain height, but changes the degree of grinding contact by adjusting the pre-compression state of the supporting spring 118 within the normal grinding range, and allows the floating seat 10 to float within a corresponding small range. After the first cutting edge to be processed is ground, the reciprocating motor 75 is stopped first, so that the reciprocating slide 6 stops reciprocating. At the same time, the grinding motor 4 is stopped. After the grinding disc 3 stops rotating, the blade is changed. The operator continues to rotate the adjusting handwheel 115 in the direction that raises the support plate 116, so that the relatively high position of the upper surface of the wedge adjusting block 112 is further moved to below the lifting roller 117. The lifting roller 117 drives the support plate 116 to continue to move upward along the guide rod 9, so that the compression degree of the support spring 118 is further increased, and its upward force on the floating seat 10 is gradually increased. As the support plate 116 continues to rise, the actual contact between the blade and the grinding disc 3 gradually decreases. When the upward force generated by the support spring 118 can push the floating seat 10 to move upward, the floating seat 10 moves upward along the guide rod 9, and simultaneously drives the suspension 12, adjustment box 13, tilting frame 14, blade clamping assembly 15 and the entire blade to move upward, so that the blade is completely separated from the working surface of the grinding disc 3, and a vertical clearance gap is formed between the blade and the grinding disc 3 for the tilting frame 14 to rotate. After the floating seat 10 moves upward, the support spring 118 can release a corresponding portion of the compression as the position of the floating seat 10 changes, so that the floating seat 10 is kept in a clearance position that can complete the blade surface switching. After sufficient clearance is formed between the blade and the grinding disc 3, loosen the positioning bolt 21, rotate the flipping frame 14 according to the target geometry of the second blade surface to be processed, so that the blade changes angle around the flipping axis 18 with the flipping frame 14, and observe the position of the flipping frame 14 through the indicator needle 22 and the angle scale 23. After the second blade surface to be processed forms the required second grinding posture relative to the grinding disc 3, tighten the positioning bolt 21 again to fix the flipping frame 14 in the second processing position. The rotation position of the second blade surface to be processed is determined according to the actual target blade shape of the blade, and it is not required to fix the rotation at a predetermined uniform angle relative to the first blade surface to be processed. After the angle adjustment of the second cutting edge to be processed is completed, the adjusting handwheel 115 is rotated in the opposite direction, so that the adjusting screw 114 drives the wedge adjusting block 112 to move in the opposite direction. The lifting roller 117 and the support plate 116 gradually decrease, so that the supporting spring 118 gradually reduces the upward supporting effect on the floating seat 10. The floating seat 10 and the structure above it move downward along the guide rod 9, so that the second cutting edge to be processed gradually approaches the grinding disc 3. After the second cutting edge to be processed re-establishes contact with the grinding disc 3, the position of the support plate 116 is further finely adjusted by adjusting the handwheel 115, so that the second cutting edge to be processed obtains a grinding contact state corresponding to the current grinding stage. After the grinding posture and grinding pressure of the second cutting edge to be processed are adjusted, the grinding motor 4 is started again to make the grinding disc 3 resume rotation. Then the reciprocating motor 75 is started to make the reciprocating slide 6 move back and forth along the guide rail 5 again, and the reciprocating grinding of the second cutting edge to be processed is completed in the same way as the first cutting edge to be processed. For symmetrical double-edged blades, the two blades can be adjusted to the grinding position corresponding to their respective target angles. For asymmetrical double-edged blades, they can be processed according to the different target angles of the two blades. Thus, the same blade can complete the sequential grinding of multiple blades in one clamping state. After the two cutting edges have been rough ground, if fine grinding and edge finishing are still required, the grinding motor 4 and reciprocating motor 75 can be stopped, and the corresponding grinding disc 3 and grinding media can be replaced according to the subsequent processing requirements. Then, the processing can continue in the manner described above, including angle adjustment, slow cutting, grinding pressure adjustment, reciprocating floating grinding, vertical avoidance, and cutting edge switching. When entering the fine grinding stage, the upward support of the support spring 118 on the floating seat 10 can be appropriately increased so that the blade is processed in a relatively light grinding contact state, reducing the possibility of chipping and local over-grinding of small cutting edges due to excessive grinding load. After all grinding is completed, stop the reciprocating motor 75 and the grinding motor 4. After the grinding disc 3 has completely stopped rotating, the floating seat 10 and the blade can be appropriately raised through the pressure regulating component 11 to keep the blade separated from the grinding disc 3. Then loosen the clamping bolt 153 to release the clamping pad 154 from the blade and remove the finished medical diamond blade from the clamping seat 151. This completes one grinding process of the medical diamond blade. Through the rotation of the grinding disc 3, the reciprocating motion of the reciprocating slide 6, the elastic floating formed by the floating seat 10 and the supporting spring 118, the grinding pressure adjustment and vertical avoidance formed by the pressure regulating component 11, and the blade angle switching formed by the flipping frame 14, the medical diamond blade can be continuously adjusted and processed according to different blade surfaces and different grinding stages in a single clamping state.
