Description

Technical Field

[0001] This utility model relates to the technical field of blade grinding equipment, specifically to a rapid blade grinding device and an automated production system using the same. Background Technology

[0002] Cutting tools can be categorized into diamond cutting tools, alloy cutting tools, and carbon steel cutting tools, among others. They are characterized by high temperature resistance, wear resistance, and excellent sharpness, making them essential tools in hardware processing, lathe machining, stone processing, and other processes. Currently, the sharpening of cutting tools mainly relies on manual labor combined with a grinding wheel machine. This method suffers from low efficiency and a lack of standardization.

[0003] Chinese utility model patent application number 202021554623.0 discloses a diamond tip arc surface grinding mechanism. While this mechanism can automatically raise the diamond tip using a clamping component, allowing the grinding component to grind the arc surface of the diamond tip, and then laterally convey batches of diamond tips to the clamping component via a spring clip, the grinding effect of the tip's arc surface depends on the grinding wheel of the grinding component not being excessively worn or its diameter not falling below a standard threshold. This necessitates frequent checks and replacements of the grinding wheel diameter, significantly impacting the efficiency of batch grinding. If worn-out grinding wheels that do not meet the diameter standard cannot be replaced in time, a batch of defective diamond tips will result. Utility Model Content

[0004] In view of this, it is necessary to address the defects and shortcomings of the existing technology by proposing a rapid tool grinding device and an automated production system using it, thereby improving the efficiency of batch grinding of curved tool heads and reducing the defect rate of tool heads after grinding the curved surface.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model proposes a rapid tool head grinding device for rapidly grinding the arc surface of an input tool head. The device includes a first pneumatic clamp, a first clamp transmission mechanism for mounting and driving the first pneumatic clamp, a second pneumatic clamp, a second clamp transmission mechanism for mounting and driving the second pneumatic clamp, a grinding machine including a drive motor and a rotating grinding wheel driven by the drive motor, and a mounting support frame. The mounting support frame is used to fix the first clamp transmission mechanism, the second clamp transmission mechanism, and the grinding machine. The first clamp transmission mechanism is used to cyclically grip a single tool head through the first pneumatic clamp and then transmit the tool head to the front of the second pneumatic clamp. The second clamp transmission mechanism is used to cyclically pass through... After the second pneumatic clamp picks up the cutting head located on the first pneumatic clamp, it transmits the cutting head to the side of the rotating grinding wheel. The rotating grinding wheel then grinds the arc surface of the cutting head clamped by the second pneumatic clamp. The second pneumatic clamp is used to clamp the cutting head whose arc surface faces the grinding side of the rotating grinding wheel during grinding. The positional relationship between the first virtual geometric center point of the second pneumatic clamp and the center of gravity of the cutting head clamped by the second pneumatic clamp or the second virtual geometric center point of the cutting head is relatively fixed. Under the clamping action of the second pneumatic clamp and the transmission action of the second clamp transmission mechanism, and when the arc surface of the cutting head is ground, the grinding movement trajectory of the first virtual geometric center point of the second pneumatic clamp is arc-shaped.

[0007] Furthermore, the virtual plane containing the grinding movement trajectory is perpendicular to the circular end face of the rotating grinding wheel; the virtual plane containing the grinding movement trajectory is parallel to the horizontal plane.

[0008] Furthermore, in a virtual spatial coordinate system, as the first virtual geometric center point of the second pneumatic fixture moves along the arc-shaped grinding trajectory, the back side of the cutter head clamped by the second pneumatic fixture is longitudinally projected onto the grinding side of the rotating grinding wheel.

[0009] Furthermore, the back face of the cutter head, which is clamped by the second pneumatic clamp, is projected longitudinally onto the virtual center of the rotating grinding wheel.

[0010] Furthermore, as the first virtual geometric center point of the second pneumatic fixture moves along the arc-shaped grinding trajectory, the dynamic grinding area of ​​the cutting head being ground on the arc surface gradually shifts from one end of the arc surface of the cutting head clamped by the second pneumatic fixture along the length direction of the arc surface of the cutting head clamped by the second pneumatic fixture to the other end of the arc surface of the cutting head clamped by the second pneumatic fixture; the dynamic grinding area is a local area where the dynamic position of the arc surface of the cutting head clamped by the second pneumatic fixture in contact with the rotating grinding wheel changes during grinding.

[0011] Furthermore, during the process of grinding the curved surface of the cutter head, the virtual line connecting the virtual center of the grinding movement trajectory and the third virtual geometric center point of the dynamic grinding area is perpendicular to a virtual vertical side of the second pneumatic fixture used for embedding the cutter head.

[0023] Furthermore, the first pneumatic clamp includes a first clamping cylinder, an upper clamping gripper, a lower clamping gripper, an elastically reset transverse left push rod, and an elastically reset transverse right push rod; the upper clamping gripper is mounted on the upper clamping arm of the first clamping cylinder, and the lower clamping gripper is mounted on the lower clamping arm of the first clamping cylinder, and the first clamping cylinder causes the upper clamping gripper and the lower clamping gripper to cyclically perform longitudinal up and down clamping of the cutter head;

[0024] The elastic reset lateral left push rod and the elastic reset lateral right push rod are respectively installed on both sides of the first clamping cylinder. One end of the elastic reset lateral left push rod is used to limit the left side of the cutter head facing the longitudinal side of the first clamping cylinder, and one end of the elastic reset lateral right push rod is used to limit the right side of the cutter head facing the longitudinal side of the first clamping cylinder.

[0052] Example 1

[0053] like Figures 1-4 As shown:

[0054] This embodiment proposes a rapid tool head grinding device for rapidly grinding the arc surface of an input tool head. The device includes a first pneumatic clamp 1, a first clamp transmission mechanism 2 for mounting and driving the first pneumatic clamp 1, a second pneumatic clamp 3, a second clamp transmission mechanism 4 for mounting and driving the second pneumatic clamp 3, a grinding machine 5 including a drive motor 51 and a rotating grinding wheel 52 driven by the drive motor 51, and a mounting support frame 7. The mounting support frame 7 is used to fix the first clamp transmission mechanism 2, the second clamp transmission mechanism 4, and the grinding machine 5. The first clamp transmission mechanism 2 is used to cyclically grip a single tool head through the first pneumatic clamp 1 and then transmit the tool head to the front of the second pneumatic clamp 3 (e.g., ...). Figure 1As shown (specifically, longitudinally forward); the second clamping transmission mechanism 4 is used to cyclically clamp the cutting head located on the first pneumatic clamp 1 through the second pneumatic clamp 3, and then transmit the cutting head to the side of the rotating grinding wheel 52, so that the arc surface 200 of the cutting head clamped by the second pneumatic clamp 3 is ground by the rotating grinding wheel 52. The second pneumatic clamp 3 is used to clamp the cutting head whose arc surface faces the grinding side 521 of the grinding wheel 52 during grinding. The positional relationship between the first virtual geometric center point of the second pneumatic clamp 3 and the center of gravity of the cutting head clamped by the second pneumatic clamp 3 or the second virtual geometric center point of the cutting head is relatively fixed. Under the clamping action of the second pneumatic clamp 3 and the transmission action of the second clamping transmission mechanism 4, and when the arc surface 200 of the cutting head is ground, the grinding movement trajectory 100 of the first virtual geometric center point of the second pneumatic clamp 3 is arc-shaped.

[0055] The rapid tool sharpening device of this embodiment increases the speed of sharpening curved tool tips and reduces the defect rate of tool tips after sharpening curved surfaces. It avoids the harm to workers caused by manual sharpening, thereby reducing production and maintenance costs. The rapid tool sharpening device of this embodiment can also be adapted for automated or semi-automated retrofit designs.

[0056] Example 2

[0057] Example 2 is a further optimized design of Example 1;

[0058] like Figures 1-4 As shown:

[0059] The virtual plane on which the grinding movement trajectory 100 is located is perpendicular to the circular end face 522 of the rotating grinding wheel 52; the virtual plane on which the grinding movement trajectory 100 is located is parallel to the horizontal plane.

[0060] Example 3

[0061] Example 3 is a further optimized design of Example 1 or Example 2;

[0062] like Figures 1-4 As shown:

[0063] In a virtual spatial coordinate system, as the first virtual geometric center point of the second pneumatic clamp 3 moves along the arc-shaped grinding movement trajectory 100, the back side of the cutter head clamped by the second pneumatic clamp 3 is longitudinally projected onto the grinding side 521 of the rotating grinding wheel 52.

[0064] Example 4

[0065] Example 4 is a further optimized design of Example 1, Example 2, or Example 3;

[0066] like Figures 1-4 As shown:

[0067] The back of the cutting head, which is clamped by the second pneumatic clamp 3, is projected longitudinally onto the virtual center of the rotating grinding wheel 52.

[0068] Example 5

[0069] Example 5 is a further optimized design of Example 1, Example 2, Example 3, or Example 4;

[0070] like Figures 1-4 As shown:

[0071] As the first virtual geometric center point of the second pneumatic clamp 3 moves along the arc-shaped grinding trajectory 100, the dynamic grinding area of ​​the cutting head being ground on the arc surface 200 gradually shifts from one end of the arc surface 200 of the cutting head clamped by the second pneumatic clamp 3 along the length direction of the arc surface 200 of the cutting head clamped by the second pneumatic clamp 3 to the other end of the arc surface 200 of the cutting head clamped by the second pneumatic clamp 3; the dynamic grinding area is the local area where the arc surface 200 of the cutting head clamped by the second pneumatic clamp 3 contacts the rotating grinding wheel 52 during grinding, and the dynamic position changes.

[0072] Ideally, during the grinding of the cutter head on the arc surface 200, the virtual line connecting the virtual center of the grinding movement trajectory 100 and the third virtual geometric center point of the dynamic grinding area is perpendicular to a virtual vertical side of the second pneumatic clamp 3 used for embedding the cutter head (that is, during the grinding of the cutter head on the arc surface 200, the edge arc of the cutter head clamped by the second pneumatic clamp 3 and the virtual line connecting the virtual center of the grinding movement trajectory 100 forms a virtual equilateral sector).

[0073] Example 6

[0074] Example 6 is a further optimized design of Example 1, Example 2, Example 3, Example 4, or Example 5;

[0075] like Figures 1-10 As shown:

[0076] The second clamp transmission mechanism 4 includes a second transverse linear transmission assembly 41, a second longitudinal linear transmission assembly 42, and a servo assembly 43 with a swing arm that swings around a vertical virtual central axis 500; the second transverse linear transmission assembly 41 includes a first mounting bracket 411, a first drive unit 412, and a second transverse moving stage 413 driven by the first drive unit 412; the second longitudinal linear transmission assembly 42 includes a second mounting bracket 421, a second drive unit 422, and a second longitudinal moving stage 423 driven by the second drive unit 422; the second pneumatic clamp 3 is installed on the swing arm of the servo assembly 43, thereby realizing the cyclic swing of the second pneumatic clamp 3 within an angle range; the servo assembly 43 is installed on the second longitudinal moving platform 423 of the second longitudinal linear transmission assembly 42, thereby realizing the servo assembly 43 reciprocating linearly in the longitudinal direction; the second longitudinal linear transmission assembly 42 is installed on the second transverse moving platform 413 of the second transverse linear transmission assembly 41, thereby realizing the second longitudinal linear transmission assembly 42 reciprocating linearly in the transverse direction; the second transverse linear transmission assembly 41 is installed on the mounting support frame 7.

[0077] Ideally, under the clamping action of the second pneumatic clamp 3 and the transmission action of the second clamp transmission mechanism 4, and when the arc surface 200 of the cutter head is polished, the movement trajectory of the fourth virtual geometric center point of the second longitudinal moving stage 423 is arc-shaped.

[0078] Ideally, the second transverse linear transmission assembly 41 is mounted transversely on the mounting support frame 7. Both the second transverse linear transmission assembly 41 and the grinding wheel 5 are mounted on the mounting support frame 7, and the second transverse linear transmission assembly 41 and the grinding wheel 5 are longitudinally spaced apart.

[0079] Optimally, the first clamp transmission mechanism 2 includes a first transverse linear transmission assembly 21 and a first longitudinal linear transmission assembly 22; the first transverse linear transmission assembly 21 includes a third mounting bracket 211, a third drive unit 212, and a first transverse moving stage 213 driven by the third drive unit 212; the first longitudinal linear transmission assembly 22 includes a fourth mounting bracket 221, a fourth drive unit 222, and a first longitudinal moving stage 223 driven by the fourth drive unit 222; the second pneumatic clamp 3 is mounted on the first longitudinal moving stage 223, thereby realizing the second pneumatic clamp 3's longitudinal linear reciprocating motion; the first longitudinal linear transmission assembly 22 is mounted on the first transverse moving stage 213, thereby realizing the first longitudinal linear transmission assembly 22's transverse linear reciprocating motion.

[0080] The first transverse linear transmission assembly 21 is mounted on the mounting support frame 7;

[0081] The first transverse linear transmission assembly 21 and the second transverse linear transmission assembly 41 are both mounted transversely on the mounting support frame 7, and the first transverse linear transmission assembly 21 and the second transverse linear transmission assembly 41 are arranged longitudinally at intervals between each other.

[0082] When the first longitudinal linear transmission assembly 22 is driven to the lateral end position of the first transverse linear transmission assembly 21, the second longitudinal linear transmission assembly 42 is simultaneously driven to the lateral beginning position of the second transverse linear transmission assembly 41. At this time, the first pneumatic clamp 1 and the second pneumatic clamp 3 face each other longitudinally.

[0083] Specifically, when the first virtual geometric center point of the second pneumatic fixture 3 moves to the starting point of the virtual trajectory line that realizes the grinding movement trajectory 100, the servo motor assembly 43, under the action of the second transverse linear transmission assembly 41 and the second longitudinal linear transmission assembly 42, executes the rotation of the second pneumatic fixture 3 around a vertical virtual central axis 500. During this process, the horizontal and vertical coordinates of the second pneumatic fixture 3 in the spatial coordinate system continuously change, thereby making the grinding movement trajectory 100 of the first virtual geometric center point of the second pneumatic fixture 3 arc-shaped. This not only improves the production efficiency of batch grinding of the cutting head with the arc surface 200, but also improves the quality of grinding the arc surface 200, thereby increasing the service life of the tools with the cutting head welded on.

[0084] Optimally, the rapid grinding device for the cutting head also includes a first guide rail 8, a first slider 9 that cooperates with the first guide rail 8 and performs guiding movement, and a first spring 10;

[0085] A first guide rail 8 and a first slider 9 are installed between the second pneumatic clamp 3 and the swing arm of the servo assembly 43. The first guide rail 8 and the first slider 9 guide the movement of the swing arm of the second pneumatic clamp 3 and the servo assembly 43. One end of the first spring 10 presses against the second pneumatic clamp 3, and the force of the first spring 10 on the second pneumatic clamp 3 is directed towards the end of the first guide rail 8 that is closer to the grinding wheel 5. Specifically, the other end of the first spring 10 presses against the cutting plane of the shaft of the central rotating shaft of the servo assembly 43.

[0086] Optimized, the rapid grinding device for the cutting head also includes a first electronic detection trigger 600 and a second electronic detection trigger 700 (optionally, one electronic detection trigger is connected to the positive terminal of a power supply, and the other electronic detection trigger is connected to the signal input terminal of a controller; both are conductive iron pillars). The second electronic detection trigger 700 is mounted on the second pneumatic clamp 3, and the first electronic detection trigger 600 is mounted at the fixed center position of the relative swing arm of the servo assembly 43 (specifically, the central rotation axis of the servo assembly 43). When the arc surface of the cutting head held by the second pneumatic clamp 3 presses against the rotating grinding wheel 52, the second pneumatic clamp 3 guides the compression of the first spring 10, causing the first electronic detection trigger 600 to approach or contact the second electronic detection trigger 700, thereby triggering a signal. When the arc surface of the cutting head held by the second pneumatic clamp 3 does not press against the rotating grinding wheel 52, the first spring 10 returns to its original deformation, and the first electronic detection trigger 600 and the second electronic detection trigger 700 move away from or separate.

[0087] The second pneumatic clamp 3 includes a second clamping cylinder 34, a second downward pressing block 31, a second upward pressing block 32, and a cutter head ejection cylinder 33; the second downward pressing block 31 and the second upward pressing block 32 clamp the cutter head in cooperation with the second clamping cylinder 34; the cutter head ejection cylinder 33 is used to push the cutter head away after grinding, so that the cutter head is away from the second downward pressing block 31 and the second upward pressing block 32.

[0088] Optimally, the first pneumatic clamp 1 includes a first clamping cylinder 11, an upper clamping gripper 12, a lower clamping gripper 13, an elastically reset transverse left push rod 14, and an elastically reset transverse right push rod 15; the upper clamping gripper 12 is mounted on the upper clamping arm of the first clamping cylinder 11, and the lower clamping gripper 13 is mounted on the lower clamping arm of the first clamping cylinder 11; the first clamping cylinder 11 causes the upper clamping gripper 12 and the lower clamping gripper 13 to cyclically perform longitudinal up and down clamping of the cutter head;

[0089] The elastic reset transverse left push rod 14 and the elastic reset transverse right push rod 15 are respectively installed on both sides of the first clamping cylinder 11. One end of the elastic reset transverse left push rod 14 is used to limit the left side of the cutter head facing the longitudinal side of the first clamping cylinder 11, and one end of the elastic reset transverse right push rod 15 is used to limit the right side of the cutter head facing the longitudinal side of the first clamping cylinder 11.

[0090] Optimally, the upper clamping gripper 12 includes a first L-shaped pressing finger 121, a second L-shaped pressing finger 122, and a first intermediate connecting rod 123; the two ends of the first intermediate connecting rod 123 are respectively fixedly connected to one end of the first L-shaped pressing finger 121 and one end of the second L-shaped pressing finger 122; the other end of the first L-shaped pressing finger 121 is used to press down the top surface of the left end of the cutter head when the upper clamping gripper 12 and the lower clamping gripper 13 jointly clamp the cutter head; the other end of the second L-shaped pressing finger 122 is used to press down the top surface of the right end of the cutter head when the upper clamping gripper 12 and the lower clamping gripper 13 jointly clamp the cutter head; the first L-shaped pressing finger 121, the second L-shaped pressing finger 122, and the first intermediate connecting rod 123 form a hook-claw structure;

[0091] The lower clamping gripper 13 includes a third L-shaped pressing finger 131, a fourth L-shaped pressing finger 132, and a second intermediate connecting rod 133. The two ends of the second intermediate connecting rod 133 are fixedly connected to one end of the third L-shaped pressing finger 131 and one end of the fourth L-shaped pressing finger 132, respectively. The other end of the third L-shaped pressing finger 131 is used to press down the bottom surface of the left end of the cutter head when the upper clamping gripper 12 and the lower clamping gripper 13 clamp the cutter head together. The other end of the fourth L-shaped pressing finger 132 is used to press down the bottom surface of the right end of the cutter head when the upper clamping gripper 12 and the lower clamping gripper 13 clamp the cutter head together. The third L-shaped pressing finger 131, the fourth L-shaped pressing finger 132, and the second intermediate connecting rod 133 form another hook-claw structure.

[0092] In one optional implementation, the working principle of the second pneumatic clamp 3 is to use a cylinder to push the clamping robot arm, which is connected to two springs, and drives the middle top plate. The middle top plate pushes against both sides of the arc-shaped cutter head to align the cutter head. When the cutter head is aligned, the left push plate with the cylinder pushes the cutter head to make the cutter head centered on the two jaws of the clamping robot arm. During grinding, the center line of the cutter head is aligned with the center line of the grinding wheel.

[0093] In one alternative implementation, the first pneumatic clamp 1 works by using a two-jaw manipulator to clamp the cutter head at two points in the middle of the cutter head, thus avoiding the burrs around the cutter head (generated by the previous sintering process). (Existing equipment uses upper and lower plates to clamp the cutter head. When clamping a cutter head with burrs, it will cause the cutter head to be uneven and unstable, thereby affecting the grinding quality.)

[0094] Specifically, the side view structure of each L-shaped pressure finger is L-shaped.

[0095] Example 7

[0096] Example 7 is a further optimized design of any of the above embodiments to further improve automated production efficiency;

[0097] like Figures 1-10 As shown:

[0098] This embodiment proposes an automated production system for a rapid blade grinding device using any of the technical solutions described in any of the above embodiments, including:

[0099] The aforementioned rapid grinding device for cutting heads;

[0100] A linear conveyor 300 is mounted on the mounting support frame 7 to convey multiple cutting heads one by one to the lateral head position of the first clamping transmission mechanism 2, so that the cutting heads can be easily clamped by the first pneumatic clamp 1.

[0101] Ideally, the automated production system also includes a vibrating discharge rotary table 400;

[0102] The vibrating discharge rotary table 400 is used to load multiple cutting heads that need to be ground in batches; the discharge port of the vibrating discharge rotary table 400 for outputting a single cutting head is connected to the inlet port at the head end of the linear conveyor 300.

[0103] The arc surface 200 of the cutter head located at the discharge port of the vibrating discharge rotary disk 400 faces the positive Y-axis direction of a spatial rectangular coordinate system; the arc surface 200 of the cutter head located on the conveying channel unit 3003 of the linear conveying device 300 faces the positive Y-axis direction of a spatial rectangular coordinate system; the extension direction of the first pneumatic clamp 1 faces the negative Y-axis direction of a spatial rectangular coordinate system.

[0104] Optimally, the linear conveying device 300 includes a conveying channel unit 3003 for conveying the cutter head, a conveying power unit 3004 for conveying the cutter head on the cutter head conveying channel unit 3003, and a pneumatic alignment mechanism disposed at the end of the conveying channel unit 3003; the pneumatic alignment mechanism includes a pneumatic element 3002 and a hook member 3001 fixed to a telescopic rod of the pneumatic element 3002; the hook member 3001 is used to hook and pull back the cutter head protruding from the end of the conveying channel unit 3003, which has stopped transmission, so that the cutter head located at the end of the conveying channel unit 3003 is clamped by the first pneumatic clamp 1 at a designated position.

[0105] In a further optimized manner, the cutter head conveying channel unit 3003 is an inclined guide rail groove, and the conveying power unit 3004 is a vibration source device.

[0106] The automated production system in this embodiment improves the automation efficiency of batch grinding of curved cutting heads and reduces the defect rate of cutting heads after grinding curved surfaces, thereby improving the overall quality of batch grinding of curved cutting heads, avoiding the harm to workers caused by manual grinding, and thus reducing production and maintenance costs.

[0107] The working process of the automated production system in this embodiment is as follows:

[0108] The vibrating discharge rotary table 400 sequentially outputs individual cutter heads to the feed inlet at the beginning of the linear conveyor 300 in batches;

[0109] The linear conveyor transmits more than 300 cutting heads one by one to the lateral head position of the first clamping transmission mechanism 2.

[0110] The first pneumatic clamp 1, under the action of the first clamp transmission mechanism 2, clamps a single cutting head and transmits the cutting head to the front of the second pneumatic clamp 3;

[0111] After the second clamping transmission mechanism 4 clamps the cutting head located on the first pneumatic clamp 1 through the second pneumatic clamp 3, it transmits the cutting head to the side of the rotating grinding wheel 52.

[0112] Under the action of the second clamp transmission mechanism 4, the second pneumatic clamp 3 grinds the arc surface 200 of the cutter head clamped by the second pneumatic clamp 3 by rotating the grinding wheel 52. When the arc surface 200 of the cutter head is ground, the grinding movement trajectory 100 of the first virtual geometric center point of the second pneumatic clamp 3 is arc-shaped.

[0113] This utility model also has the following advantages:

[0114] This invention is applicable to the automatic grinding of the welded surface of diamond alloy cutting tools, replacing manual grinding, and has the advantages of high grinding efficiency, good grinding quality, environmental protection and safety;

[0115] This invention supports grinding of the welded surface of a cutting head with any arc within a thickness of four millimeters;

[0116] This invention can be used for grinding diamond alloy cutting heads, specifically grinding the arc-shaped welding surface of the cutting head (removing the oxide layer), and then silver-bracing, copper-bracing, or laser-welding it to a steel substrate to form a diamond saw blade. It can also be applied to grinding other diamond alloy cutting heads, such as those with flat welding surfaces, which can be silver-braced, copper-braced, or laser-welded to a steel substrate to form diamond grinding wheels, diamond grinding blocks, and other tools, thus enabling multiple grinding methods to be performed in one machine.

[0117] This utility model employs three motors working in concert to follow the arc of the cutting head and follow the arc trajectory of the cutting head's grinding surface, which is then ground by the grinding wheel, resulting in uniform removal of the ground surface.

[0118] The tool head rapid grinding device of this utility model effectively simulates the human hand, clamps the tool head, moves out of the arc trajectory of the tool head grinding surface, and grinds against the rotating grinding wheel in a fixed position;

[0119] This invention features a function that maintains a constant linear speed of rotation of the grinding wheel; as the grinding wheel grinds against the diamond alloy cutting head, the diameter of the grinding wheel will decrease.

[0120] This utility model can be fitted with an organic glass main unit cover and a vibrating plate cover to achieve sound insulation and dustproof effect; each guide rail of the actuator of this utility model can also be fitted with a retractable dustproof cover.

[0121] Compared to high-precision robotic arms, this invention also has the advantages of low cost, easy maintenance and repair, and high production efficiency (suitable for mass production in factories).

[0122] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
