Description

A grinding machine diamond wheel dressing device

Technical Field

The invention relates to the technical field of grinding tool processing, in particular to a grinding machine diamond grinding wheel dressing device.

Background Art

Grinding wheels are commonly used components in grinding operations. After long-term use, the grinding surface of the grinding wheel will undergo a certain degree of wear. Therefore, it is necessary to use a grinding wheel dresser to dress the grinding surface of the grinding wheel and remove the dull surface to restore the grinding performance of the grinding wheel.

A Chinese patent document with the announcement number CN218613476U discloses a grinding wheel dresser, which, when in use, drives the driving screw to rotate through a power motor, thereby enabling the driving block to translate along the driving screw, driving the execution screw and the dressing head fixed to the execution screw to translate, and dressing different positions of the grinding wheel, thereby dressing the arc surface and end surface of the grinding wheel to different degrees as needed. In this technical solution, although the arc surface and end surface of the grinding wheel can be dressed to different degrees as needed; however, when dressing the chamfered surface of the outer edge of the grinding wheel as shown in Figure 1, it is necessary to replace different dressing heads. Since the machine needs to be stopped for replacement when replacing different dressing heads, the dressing efficiency of the grinding wheel dresser is reduced.

For the trimming of the chamfered surface of the outer edge of the grinding wheel, a Chinese patent document with announcement number CN209335408U discloses a grinding wheel dresser, including a mounting seat, a stand on both sides of the mounting seat, a fixing hole on the top of the left stand, a fixed top installed in the fixing hole, a screw hole on the right stand, an adjustable top installed in the screw hole, and a knob plate on the outer end of the adjustable top; support shafts are provided at both ends of the rotating bracket, and the part where the support shaft contacts the top is a funnel groove; a processing hole is provided in the central part of the rotating bracket, and a bolt is installed in the processing hole, and the bolt passes through the through hole on the processing tool. When in use, the outer edge of the grinding wheel is ground by adjusting the angle of the processing tool to contact the chamfered surface of the outer edge of the grinding wheel. Although the processing tool of the grinding wheel dresser can adjust the angle, the processing tool cannot rotate while adjusting the angle, resulting in the processing tool (dressing head) During the process of dressing the grinding wheel, a certain position on the processing tool (dressing head) that contacts the grinding wheel is continuously worn, affecting the dressing effect of the grinding wheel.

In summary, the above-mentioned grinding wheel dresser can only dress the grinding wheel arc surface or the chamfered surface of the grinding wheel outer edge, and cannot prevent a certain part of the dressing head that contacts the grinding wheel from being continuously worn.

Summary of the invention

A driving mechanism, disposed on the sliding seat, for driving the swing seat to slide along the arc-shaped guide rail;

The locking device is arranged on the sliding seat and is used for locking or unlocking the rotating disk.

The beneficial effects of the present invention are:

1. When the present invention is in use, the diamond grinding wheel dressing device of the grinding machine is installed below the grinding wheel to be dressed, and the sliding seat is horizontally slidably arranged on the mounting seat along the width direction of the grinding wheel to be dressed. When the arc surface of the grinding wheel needs to be dressed, the sliding seat can be pushed to move along the mounting seat to the required position below the arc surface of the grinding wheel, and the sliding seat is locked to move relative to the mounting seat, and the angle of the dressing head is adjusted to make the dressing head move to face the arc surface of the grinding wheel. At this time, the turntable is in a locked state, the driving mechanism is in an unstarted state, and the grinding wheel is driven to rotate by the power source of the grinding machine. In this way, the dressing head contacts the arc surface of the grinding wheel, and the arc surface of the grinding wheel can be ground to achieve the effect of dressing the arc surface of the grinding wheel.

2. When the chamfered surface of the outer edge of the grinding wheel needs to be trimmed, the sliding seat can be pushed to move along the mounting seat to the position of the outer edge of the grinding wheel, and the sliding seat can be locked relative to the mounting seat. The angle of the dressing head can be adjusted so that the dressing head and the chamfered surface are set at an angle. At this time, the turntable is in a locked state, the driving mechanism is in an unstarted state, and the grinding wheel is driven to rotate by the power source of the grinding machine. In this way, the dressing head contacts the chamfered surface of the edge of the grinding wheel, and the chamfered surface of the outer edge of the grinding wheel can be ground to achieve the effect of trimming the chamfered surface of the grinding wheel.

3. When adjusting the angle of the trimming head, the turntable is unlocked by the locking device. At this time, the driving mechanism is started to drive the swing seat to slide along the arc guide rail. Since the arc guide rail is arranged along the sliding direction of the mounting seat, and the arc concave surface of the arc guide rail faces away from the mounting seat, the swing seat swings up and down along the sliding direction of the sliding seat under the drive of the driving mechanism. Since the fixed sleeve is vertically fixed on the end surface of the swing seat facing away from the sliding seat, and the fixed sleeve is equipped with a rotating sleeve extending along its own axial direction, and the trimming head is fixed on the rotating sleeve, and the trimming head is coaxial with the rotating sleeve, the trimming head also swings up and down along the sliding direction of the sliding seat with the swing seat, thereby achieving the effect of adjusting the angle of the trimming head. The gear on the rotating disk is meshed with the arc-shaped rack on the sliding disk, and the arc-shaped track of the arc-shaped rack is the same as the arc-shaped track of the arc-shaped guide rail. Therefore, when the rotating disk swings with the swinging disk, the gear on the rotating disk is meshed with the arc-shaped rack for transmission. The meshing transmission between the gear and the arc-shaped rack drives the rotating disk to rotate. Since the opposite ends of the connecting rod are respectively hinged to the rotating disk and the slip ring, the slip ring sliding sleeve is arranged on the outer wall of the fixed sleeve, and the slip ring is supported by the elastic member sleeved on the fixed sleeve. The lever on the slip ring passes through the strip groove on the fixed sleeve and cooperates with the driving groove on the outer wall of the rotating sleeve. Therefore, the self-rotation of the rotating disk will pull the slip ring downward along the axial direction of the fixed sleeve under the action of the connecting rod, so that the elastic member The elastic member is in a compressed state, and the lever moves down along the strip groove with the slip ring. At this time, the lever moves down from the position of the locking groove to the driving inclined groove, and under the action of the inclined surface of the driving inclined groove, the lever drives the rotating sleeve to rotate. After the gear on the turntable is disengaged from the arc-shaped rack, the slip ring moves up along the fixed sleeve under the elastic force of the elastic member, and the lever moves up along the strip groove with the slip ring. During the upward movement of the lever, the gear on the turntable rotates idly, and when the lever moves up to the top of the strip groove, the lever and the locking groove cooperate to lock the rotation of the rotating sleeve, and at the same time, the locking device is used to lock the rotation of the turntable relative to the swing seat, so that the dressing head can be driven to rotate, and the dressing head is locked after rotating a certain angle, thereby preventing the dressing head from being continuously worn at the same angle and a certain part of the dressing head in contact with the grinding wheel.

Further, the driving groove includes a plurality of driving inclined grooves connected end to end along the circumference of the rotating sleeve and a plurality of locking grooves connected end to end along the circumference of the rotating sleeve, the locking groove is connected to the driving inclined groove, and the driving inclined groove and the locking groove are respectively close to and far away from the swing seat; wherein, the driving inclined groove includes a first inclined line segment and a first straight line segment extending in the axial direction of the rotating sleeve, a circular arc transition is formed between the first straight line segment and the first inclined line segment, and the first inclined line segment faces the locking groove; the locking groove includes a U-shaped line segment, a second inclined line segment and a second straight line segment extending in the axial direction of the rotating sleeve, the opposite ends of the U-shaped line segment are respectively connected to the second straight line segment and the second oblique line segment, the second oblique line segment faces the driving inclined groove, the U-shaped line segment of each locking groove corresponds to the first oblique line segment facing each driving inclined groove, and the connection part between the second oblique line segment of one locking groove and the second straight line segment of another locking groove corresponds to the first oblique line segment facing the one driving inclined groove.

Beneficial effect: when the rotating sleeve is in a locked state, the lever on the slip ring is inserted into the U-shaped end formed by the U-shaped line segment; when the rotating sleeve needs to be driven to rotate, the lever on the slip ring moves downward, and the lever moves from the U-shaped end along the strip groove to the inclined surface of the first oblique line segment, and the downward force of the lever on the inclined surface of the first oblique line segment drives the rotating sleeve to rotate counterclockwise, and the rotating sleeve performs the first rotation, so that the portion connected between the first straight line segment and the first oblique line segment moves to the corresponding position connected to the strip groove, so that the lever is located at the portion connected between the first straight line segment and the first oblique line segment; When the gear is disengaged from the arc-shaped rack, the slip ring moves up along the fixed sleeve under the elastic force of the elastic member, and the lever moves up along the strip groove with the slip ring. During the upward movement of the lever, the lever's upward force on the inclined surface of the second oblique line segment continues to drive the rotating sleeve to rotate counterclockwise. The rotating sleeve performs a second rotation, which plays a role in expanding the rotating sleeve's rotation angle, so that the U-shaped line segment connecting the second oblique line segment and the second straight line segment moves to the corresponding bar groove. At this time, the lever is in the U-shaped end formed by the U-shaped line segment, thereby locking the rotating sleeve to rotate relative to the fixed sleeve. It can be seen that through the structure of the above-mentioned drive groove, the angle adjustment of the dressing head is synchronized with the self-rotation of the dressing head, and the position of the grinding wheel of the dressing head can be synchronously updated each time the angle of the dressing head is adjusted.

Furthermore, a first guiding slope is provided at a connection portion between the second oblique line segment of one locking groove and the second straight line segment of another locking groove, and the first guiding slope has the same inclination direction as the first oblique line segment.

The radius of the gear 420 is smaller than the radius of the turntable 42. Each gear 420 is meshed with each arcuate rack 31.

2, 3, 5, 6 and 7, the surface of the swing seat 4 facing the sliding seat 3 is set as an arc surface with the same arc as the arc guide rail 30, so that the volume of the swing seat 4 can be reduced and the arc worm gear rack 52 can be processed. A fixed sleeve 41 perpendicular to the swing seat 4 is fixed on the end surface of the swing seat 4 facing away from the sliding seat 3. The fixed sleeve 41 is built with a rotating sleeve 45 extending along its own axial direction. The rotating sleeve 45 is provided with a dressing head 46 coaxial with the rotating sleeve 45 and used for dressing the grinding wheel 1. One end of the dressing head 46 is located in the rotating sleeve 45, and the other end of the dressing head 46 extends outside the rotating sleeve 45 for dressing the grinding wheel 1. The dressing head 46 is locked on the rotating sleeve 45 by a locking screw 460. When the dressing head 46 is damaged, the locking screw 460 can be rotated to loosen the locking of the dressing head 46 by the locking screw 460, so as to facilitate the replacement of the dressing head 46.

The outer wall of the rotating sleeve 45 is provided with a driving groove 450 along its circumference, the sliding sleeve of the outer wall of the fixed sleeve 41 is provided with a slip ring 44, the outer wall of the fixed sleeve 41 is provided with a slide groove 411 extending along its axial direction, and the inner ring of the slip ring 44 is provided with a slider 441 that slides with the slide groove 411. In this way, the smoothness of the sliding of the slip ring 44 along the axial direction of the fixed sleeve 41 can be improved to avoid affecting the self-rotation effect of the rotating sleeve 45.

An elastic member 412 is sleeved on the outer wall of the fixed sleeve 41. The elastic member 412 is a spring. The elastic member 412 is located below the slip ring 44. One end of the elastic member 412 is connected to the swing seat 4, and the other end of the elastic member 412 supports the slip ring 44.

The strip groove 410 penetrates the side wall of the fixed sleeve 41 along the second horizontal direction.

The slip ring 44 is hinged with a connecting rod 43, and one end of the connecting rod 43 facing away from the slip ring 44 is hinged to the turntable 42, so that the connecting rod 43 is hinged between the slip ring 44 and the turntable 42; in addition, a lever 440 is fixed on the slip ring 44 and passes through the strip groove 410, and the lever 440 extends along the second horizontal direction. One end of the lever 440 is fixed on the inner ring wall of the slip ring 44, and the other end of the lever 440 is inserted into the driving groove 450. The lever 440 can move along the axial direction of the fixed sleeve 41 with the slip ring 44 and be used in conjunction with the driving inclined groove 4501 or the locking groove 4502 to drive the trimming head 46 to rotate or lock the rotation of the trimming head 46.

2, 4, 5 and 10, the driving mechanism includes a driving motor 50, a worm 51 and an arcuate worm gear rack 52, the arcuate worm gear rack 52 is arranged on the surface of the swing seat 4 facing the sliding seat 3, the arcuate worm gear rack 52 is the same as the arcuate track of the arcuate guide rail 30, the driving motor 50 is connected to the worm 51, and the worm 51 is meshed with the arcuate worm gear rack 52. When it is necessary to drive the swing seat 4 to slide along the arcuate guide rail 30, the driving motor 50 is started, the worm 51 rotates under the drive of the driving motor 50, and the worm 51 is meshed with the arcuate worm gear rack 52 for transmission, so as to achieve the effect of driving the swing seat 4 to slide along the arcuate guide rail 30. Since the transmission accuracy of the worm 51 and the arcuate worm gear rack 52 is high and the transmission is stable, the swing effect of the swing seat 4 is stable and the accuracy is high. In addition, a receiving cavity 32 for receiving the worm 51 is provided on the surface of the swing seat 4 facing away from the mounting seat 2 , and the worm 51 is rotatably connected to the swing seat 4 via a bearing, thereby improving the transmission performance of the worm 51 .

Referring to Figures 2 to 14, when the grinding machine diamond wheel dressing device of the present invention is actually used, the grinding machine diamond wheel 1 dressing device is installed below the grinding wheel 1 to be dressed, wherein the structure of the dressing wheel 1 is shown in Figure 1. When the grinding wheel arc surface 10 needs to be dressed, the linear drive motor module drives the sliding seat 3 to move to the required position below the grinding wheel arc surface 10 along the horizontal first direction, and locks the sliding seat 3 relative to the mounting seat 2 to move, so that the dressing head 46 moves to face the grinding wheel arc surface 10. At this time, the turntable 42 is in a locked state, the driving mechanism is in an unstarted state, and the grinding wheel 1 is driven to rotate by the power source of the grinding machine, so that the dressing head 46 contacts the grinding wheel arc surface 10, and the grinding wheel arc surface 10 can be ground to achieve the effect of dressing the grinding wheel arc surface 10.

When the chamfered surface 11 of the outer edge of the grinding wheel 1 needs to be trimmed, the linear drive motor module drives the sliding seat 3 to move along the horizontal first direction to the position of the outer edge of the grinding wheel 1, and locks the sliding seat 3 to move relative to the mounting seat 2, and adjusts the angle of the dressing head 46 so that the dressing head 46 forms a certain angle with the chamfered surface 11 of the grinding wheel 1. At this time, the turntable 42 is in a locked state, the driving mechanism is in an unstarted state, and the grinding wheel 1 is driven to rotate by the power source of the grinding machine (not shown). In this way, the dressing head 46 contacts the chamfered surface 11 of the edge of the grinding wheel 1, and the chamfered surface 11 of the outer edge of the grinding wheel 1 can be ground, thereby achieving the effect of trimming the chamfered surface 11 of the grinding wheel 1.

When adjusting the angle of the trimming head 46, the turntable 42 is unlocked by the locking device. At this time, the driving mechanism is started to drive the swing seat 4 to slide along the arc guide rail 30. Since the arc guide rail 30 is arranged along the sliding direction of the mounting seat 2, and the arc concave surface of the arc guide rail 30 is facing away from the mounting seat 2, the swing seat 4 swings up and down along the sliding direction of the sliding seat 3 under the drive of the driving mechanism. Since the fixed sleeve 41 is vertically fixed on the end surface of the swing seat 4 facing away from the sliding seat 3, and the fixed sleeve 41 is equipped with a rotating sleeve 45 extending along its own axial direction, and the trimming head 46 is fixed on the rotating sleeve 45, and the trimming head 46 is coaxial with the rotating sleeve 45, the trimming head 46 also swings up and down along the sliding direction of the sliding seat 3 with the swing seat 4, thereby achieving the effect of adjusting the angle of the trimming head 46.

In the process of adjusting the angle of the trimming head 46, the sliding seat 3 is in a locked state. Since the turntable 42 is arranged on the swing seat 4, the turntable 42 will swing with the swing seat 4. Since the gear 420 on the turntable 42 is meshed with the arc-shaped rack 31 on the sliding seat 3, and the arc-shaped trajectory of the arc-shaped rack 31 is the same as the arc-shaped trajectory of the arc-shaped guide rail 30, the turntable 42 is in the process of swinging with the swing seat 4. The gear 420 on the turntable 42 is meshed with the arc-shaped rack 31 for transmission, and the movement trajectory of the gear 420 always follows the arc of the arc-shaped rack 31. The meshing transmission between the gear 420 and the arc-shaped rack 31 drives the turntable 42 to rotate. Since the opposite ends of the connecting rod 43 are respectively hinged with the turntable 42 and the slip ring 44, the slip ring 44 is slidably sleeved on the outer wall of the fixed sleeve 41, and the slip ring 44 is supported by the elastic member 412 sleeved on the fixed sleeve 41. The lever 440 on the slip ring 44 penetrates the strip groove 410 on the fixed sleeve 41 and cooperates with the driving groove 450 on the outer wall of the rotating sleeve 45. Therefore, the rotation of the turntable 42 will pull the slip ring 44 along the axis of the fixed sleeve 41 under the action of the connecting rod 43. The sliding ring 44 moves downward in the direction of the elastic member 412, so that the elastic member 412 is in a compressed state. At the same time, the lever 440 moves downward along the strip groove 410 with the sliding ring 44. At this time, the lever 440 moves downward from the position of the locking groove 4502 to the driving inclined groove 4501. Under the action of the inclined surface of the driving inclined groove 4501, the lever 440 drives the rotating sleeve 45 to rotate. When the gear 420 on the rotating disk 42 is disengaged from the arc-shaped rack 31, the sliding ring 44 moves upward along the fixed sleeve 41 under the elastic force of the elastic member 412, and the lever 440 moves downward along the strip groove 410 with the sliding ring 4 4, during the upward movement of the lever 440, the gear 420 on the turntable 42 rotates idly. When the lever 440 moves up to the top of the strip groove 410, the lever 440 cooperates with the locking groove 4502 to lock the rotation of the rotating sleeve 45, and at the same time, the locking device locks the turntable 42 relative to the swing seat 4, so that the dressing head 46 can be driven to rotate, and the dressing head 46 is locked after rotating a certain angle, thereby preventing the dressing head 46 from being continuously worn at a certain angle that contacts the grinding wheel 1.

It should be noted that the length of the arc rack 31 is related to the compression amount of the elastic member 412. The length of the arc rack 31 is shorter than the length of the arc guide rail 30, and the arc rack 31 is an intermittent arc rack 31, that is, the middle position of the arc rack 31 has a partition part 310, and the partition part 310 breaks the arc rack 31 and divides it into two sections of the arc rack 31. When the gear 420 moves to the partition part 310 with the swing of the swing seat 4, the gear 420 disengages from the arc rack 31. At this time, the elastic member 412 is reset, and the gear 420 on the turntable 42 is idling. The slip ring 44 moves up along the fixed sleeve 41 under the elastic force of the elastic member 412, and the lever 440 moves up along the strip groove 410 with the slip ring 44 to the locking groove 4502 to lock the rotation of the trimming head 46.

In addition, no matter whether the gear 420 moves along the arc-shaped trajectory of the arc-shaped rack 31 to the partition portion 310, so that the gear 420 is disengaged from the arc-shaped rack 31, or the gear 420 moves along the arc-shaped trajectory of the arc-shaped rack 31 beyond the length of the arc-shaped rack 31, so that the gear 420 is disengaged from the arc-shaped rack 31, as long as the gear 420 is in a disengaged state from the arc-shaped rack 31, the elastic member 412 will drive the lever 440 to move from the driving inclined groove 4501 to the locking groove 4502 under the action of its own elastic force, thereby locking the rotation of the trimming head 46.

Of course, referring to Figures 2, 11, 15 and 16, since the connecting rod 43 has a highest position and a lowest position, when the hinge point of the connecting rod 43 and the turntable 42 is in the highest position, that is, the gear 420 is in the initial state, the lever 440 is at the top end of the U-shaped line segment 45021 of the locking groove 4502, locking the rotating sleeve 45 for self-rotation, and when the hinge point of the connecting rod 43 and the turntable 42 rotates from the highest point to the lowest position, the rotation of the gear 420 drives the connecting rod 43 to drive the lever 440 to move from the locking groove 4502 to the driving inclined groove 4501. During this process, the lever 440 acts on the inclined surface of the driving inclined groove 4501 to drive the rotating sleeve 45 to rotate a certain angle; when the connecting rod 43 rotates to the lowest position, the gear 420 rotates 180°, and the lever 440 is at the lowest end of the portion connected between the first straight line segment 45012 and the first oblique line segment 45011. It can be seen that when the connecting rod 43 rotates from the highest position to the lowest position, the gear 420 rotates 180°, and the lever 440 is in the process of moving down; when the connecting rod 43 rotates from the lowest position to the highest position again, the gear 420 rotates 180°, and the lever 440 is in the process of rising. Therefore, when the gear 420 rotates by an angle greater than 180°, such as when the gear 420 rotates by an angle of 181°, the gear 420 is disengaged from the arc-shaped rack 31.

In summary, the dressing device for the diamond grinding wheel 1 of the grinding machine of the present invention can not only dress the arc surface 10 of the grinding wheel, but also can dress the chamfered surface 11 of the outer edge of the grinding wheel 1. At the same time, in the process of adjusting the angle of the dressing head 46, the dressing head 46 will be driven to rotate synchronously to avoid continuous wear of a certain part of the dressing head 46 that contacts the grinding wheel 1.

In this embodiment, referring to Fig. 11, the driving groove 450 includes a plurality of driving inclined grooves 4501 connected end to end along the circumference of the rotating sleeve 45 and a plurality of locking grooves 4502 connected end to end along the circumference of the rotating sleeve 45. The locking groove 4502 is connected to the driving inclined groove 4501, and the driving inclined groove 4501 and the locking groove 4502 are respectively close to and far from the swing seat 4, that is, the driving inclined groove 4501 is located below the locking groove 4502.

Specifically, referring to Figure 11, the driving inclined groove 4501 includes a first oblique line segment 45011 and a first straight line segment 45012 extending along the axial direction of the rotating sleeve 45, the first straight line segment 45012 is connected to the first oblique line segment 45011 by an arc transition, and the first oblique line segment 45011 faces the locking groove 4502. The locking groove 4502 includes a U-shaped line segment 45021, a second oblique line segment 45022 and a second straight line segment 45023 extending along the axial direction of the rotating sleeve 45, the opposite ends of the U-shaped line segment 45021 are respectively connected to the second straight line segment 45023 and the second oblique line segment 45022, the second oblique line segment 45022 faces the driving inclined groove 4501, the U-shaped line segment 45021 of each locking groove 4502 corresponds to the first oblique line segment 45011 of each driving inclined groove 4501, and the connection part between the second oblique line segment 45022 of a locking groove 4502 and the second straight line segment 45023 of another locking groove 4502 corresponds to the first oblique line segment 45011 of a driving inclined groove 4501.

When the driving groove 450 is actually used, when the rotating sleeve 45 is in a locked state, the lever 440 on the slip ring 44 is inserted into the U-shaped end formed by the U-shaped line segment 45021; when the rotating sleeve 45 needs to rotate, the lever 440 on the slip ring 44 moves downward, and the lever 440 moves from the U-shaped end along the strip groove 410 to the inclined surface of the first oblique line segment 45011, and the downward force of the lever 440 on the inclined surface of the first oblique line segment 45011 drives the rotating sleeve 45 to rotate counterclockwise, and the rotating sleeve 45 performs the first self-rotation at this time. The first self-rotation of the rotating sleeve 45 causes the connecting portion between the first straight line segment 45012 and the first oblique line segment 45011 to rotate to a position corresponding to the strip groove 410, so that the lever 440 is located at the connecting portion between the first straight line segment 45012 and the first oblique line segment 45011; when the gear 420 is connected to the arc-shaped rack 3 After the detachment, the sliding ring 44 moves upward along the fixing sleeve 41 under the elastic force of the elastic member 412, and the lever 440 moves upward along the strip groove 410 with the sliding ring 44. In the process of the upward movement of the lever 440, the upward force of the lever 440 on the inclined surface of the second oblique line segment 45022 continues to drive the rotating sleeve 45 to rotate counterclockwise. At this time, the rotating sleeve 45 performs a second rotation. The second rotation of the rotating sleeve 45 plays a role in expanding the rotation angle of the rotating sleeve 45. At the same time, the second rotation of the rotating sleeve 45 makes the U-shaped line segment 45021 connecting the second oblique line segment 45022 and the second straight line segment 45023 rotate to a position corresponding to the strip groove 410. At this time, the lever 440 is in the U-shaped end formed by the U-shaped line segment 45021, locking the rotating sleeve 45 to rotate relative to the fixing sleeve 41, thereby locking the trimming head 46 to rotate relative to the fixing sleeve 41. It can be seen that, through the structure of the driving groove 450 , the angle adjustment of the dressing head 46 and the rotation of the dressing head 46 are performed synchronously, and the position of the grinding wheel 1 of the dressing head 46 can be synchronously updated each time the angle of the dressing head 46 is adjusted.

In this embodiment, a first guiding inclined surface 4503 is provided at the connection position between the second oblique line segment 45022 of one locking groove 4502 and the second straight line segment 45023 of another locking groove 4502, and the first guiding inclined surface 4503 has the same inclination direction as the first oblique line segment 45011. When the lever 440 moves down from the U-shaped end to the inclined surface of the first oblique line segment 45011, under the action of the inclined surface of the first oblique line segment 45011, the lever 440 continues to move down to force the rotating sleeve 45 to rotate. In the process of driving the rotating sleeve 45 to perform the above-mentioned first rotation, the first guiding inclined surface 4503 guides the lever 440, and the first guiding inclined surface 4503 forces the lever 440 to increase the force acting on the inclined surface of the first oblique line segment 45011, thereby playing a role in assisting the rotation of the rotating sleeve 45, which is conducive to improving the rotation performance of the rotating sleeve 45 and making the rotating sleeve 45 rotate more smoothly.

In this embodiment, referring to FIG. 2, FIG. 7, FIG. 8, and FIG. 13, the locking device includes a spring latch 7, a first locking hole 71, and a second locking hole 72. The first locking hole 71 is arranged on the end surface of the rotating disk 42 facing away from the swing seat 4. The spring latch 7 is arranged on the first side 34 and the second side 35 of the sliding seat 3 along the second horizontal direction. Of course, there are multiple spring latches 7 on the first side 34 of the sliding seat 3, and the multiple spring latches 7 on the first side 34 of the sliding seat 3 are arranged along the arc track of the arc guide rail 30; there are also multiple spring latches 7 on the second side 35 of the sliding seat 3, and the multiple spring latches 7 on the second side 35 of the sliding seat 3 are also arranged along the arc track of the arc guide rail 30. Exemplarily, there are three spring latches 7 on the first side 34 and the second side 35 of the sliding seat 3; in other embodiments, there can also be four or six spring latches 7 on the first side 34 and the second side 35 of the sliding seat 3, which are not limited here. Since the turntable 42 rotates along the arc track of the arc guide rail 30, when it is necessary to lock the turntable 42 relative to the swing seat 4, the spring latch 7 corresponding to the first locking hole 71 can be inserted into the first locking hole 71 to achieve the locking effect of the turntable 42. It can be understood by those skilled in the art that in this embodiment, the spring latch 7 cooperates with the first locking hole 71 on the turntable 42 to lock, so as to facilitate the locking or unlocking of the turntable 42.

6-8, the second locking hole 72 is provided on the first side wall 402 and the second side wall 403 of the swing seat 4 which are opposite to each other along the second horizontal direction. The first side wall 402 and the second side wall 403 of the swing seat 4 are provided with a plurality of second locking holes 72. For example, in order to correspond to the spring latch 7, the first side wall 402 and the second side wall 403 of the swing seat 4 are provided with three second locking holes 72. In other embodiments, the first side wall 402 and the second side wall 403 of the swing seat 4 can also be provided with four or six second locking holes 72, which are not limited here. Among them, the plurality of second locking holes 72 of the first side wall 402 of the swing seat 4 are provided along the arc track direction of the arc guide rail 30, and the plurality of second locking holes 72 of the second side wall 403 of the swing seat 4 are also provided along the arc track direction of the arc guide rail 30.

Of course, the first locking hole 71 on one rotating disk 42 can be correspondingly communicated with any second locking hole 72 on the first side wall 402 of the swing seat 4, and the first locking hole 71 on another rotating disk 42 can be correspondingly communicated with any second locking hole 72 on the second side wall 403 of the swing seat 4. When it is necessary to lock the swing seat 4 from swinging relative to the sliding seat 3, the spring latch 7 can be passed through the first locking hole 71 on the rotating disk 42 and inserted into the second locking hole 72 on the swing seat 4, thereby locking the swing seat 4 from swinging relative to the sliding seat 3. It can be seen that in this embodiment, the spring latch 7 for locking or unlocking the turntable 42 cooperates with the second locking hole 72 on the swing seat 4 to facilitate locking or unlocking the swing seat 4 without adding an additional locking mechanism.

It should be noted that due to the transmission gap between the worm 51 and the arc-shaped worm gear rack 52 on the swing seat 4, the dressing head 46 will shake during the dressing of the grinding wheel 1. Therefore, when the angle of the dressing head 46 is adjusted to a fixed position, the present invention uses a spring pin 7 to pass through the first locking hole 71 on the turntable 42 and insert it into the second locking hole 72 on the swing seat 4, so as to achieve the purpose of locking the swing seat 4 and the turntable 42 at the same time, thereby avoiding the dressing head 46 from shaking during the dressing of the grinding wheel 1 and improving the stability of the dressing head 46 in dressing the grinding wheel 1.

2, 4, 5 and 13, the spring latch 7 is installed in the mounting hole 33 on the sliding seat 3; a plurality of mounting holes 33 penetrating the respective wall thicknesses are provided on the first side 34 and the second side 35 of the sliding seat 3 along the second horizontal direction; wherein the wall on the first side of the sliding seat 3 is the first side wall of the sliding seat 3, the wall on the second side 35 of the sliding seat 3 is the second side wall of the sliding seat 3, and the plurality of mounting holes 33 correspond one to one with the plurality of spring latches 7; the shell of the spring latch 7 is a square block 70, and the opposite ends of the square block 70 are respectively provided with a mounting portion 701 and an unlocking portion 702, the mounting portion 701 is slidably adapted to the mounting hole 33, the opposite ends of the unlocking portion 702 along the first horizontal direction are provided with a second guiding inclined surface 7021, the unlocking rod 8 is provided with a slot opening 80 for plugging with the square block 70 along the first horizontal direction, and a third guiding inclined surface 81 for adapting with the second guiding inclined surface 7021 is provided on the side of the slot opening 80 facing away from the sliding seat 3. Exemplarily, when the spring latch 7 locks the swing seat 4 and the turntable 42 in the first locking position 73, if it is necessary to unlock the spring latch 7, the linear motor module 6 drives the sliding seat 3 to move to the left along the first horizontal direction to a safe position (the safe position refers to the area away from the operation of the grinding wheel 1), so that the square block 70 of the spring latch 7 in the first locking position 73 cooperates with the unlocking rod 8 of the spring latch 7 corresponding to the first locking position 73 to unlock. In this process, the second guide bevel 7021 on the unlocking part 702 slides with the third guide bevel 81 of the slot opening 80, and the slot opening 80 of the guide unlocking rod 8 is inserted into the square block 70 of the spring latch 7, forcing the shell of the spring latch 7 to be pulled out of the mounting hole 33 for a distance, thereby automatically unlocking the spring latch 7 from locking the turntable 42 and the swing seat 4.

Similarly, when the spring latch 7 locks the swing seat 4 and the turntable 42 in the second locking position 74, if it is necessary to unlock the spring latch 7, the linear motor module 6 drives the sliding seat 3 to move leftward or rightward along the first horizontal direction to a safe position (the safe position refers to the area away from the operation of the grinding wheel 1), so that the square block 70 of the spring latch 7 in the second locking position 74 cooperates with the unlocking rod 8 of the spring latch 7 corresponding to the second locking position 74 to unlock.

In summary, the working principle of the grinding machine diamond grinding wheel 1 dressing device of the present invention is:

When the grinding wheel 1 needs to be dressed, the linear drive motor module drives the sliding seat 3 to move to the desired position along the first horizontal direction, and locks the sliding seat 3 to move relative to the mounting seat 2. At the same time, the angle of the dressing head 46 is adjusted, and the rotation of the grinding wheel 1 is utilized to contact the dressing head 46 to achieve the purpose of dressing the grinding wheel 1.

When the lever 440 moves downward, the elastic member 412 is compressed during the downward movement of the lever 440, and the downward force of the lever 440 on the inclined surface of the first oblique line segment 45011 drives the rotating sleeve 45 to rotate counterclockwise for the first time; when the gear 420 is disengaged from the arc-shaped rack 31, the slip ring 44 slides upward under the elastic force of the elastic member 412, thereby driving the lever 440 to move upward. During the upward movement of the lever 440, the gear 420 on the turntable 42 rotates idly, and the upward force of the lever 440 on the inclined surface of the second oblique line segment 45022 drives the second rotating sleeve 45 to rotate counterclockwise for the second time. When the lever 440 moves up to the top end of the strip groove 410, the lever 440 is inserted into the U-shaped end of the locking groove 4502, and the limiting rotating sleeve 45 rotates, thereby achieving the effect of locking the rotating sleeve 45 rotation.
