Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of grinding tool processing, in particular to a grinding wheel dressing device for a grinding machine. BACKGROUND

[0002] A grinding machine is a machine tool that uses a grinding tool to grind the surface of a workpiece. Most grinding machines use a high-speed rotating grinding wheel for grinding. After a period of grinding, the surface of the grinding wheel becomes uneven and needs to be dressed with a diamond pen.

[0003] A grinding machine diamond grinding wheel dressing device is disclosed in Chinese Patent No. CN118905947B, issued on October 9, 2024, and having the publication number CN118905947B. The device includes a mounting seat, a swing seat, and a sliding seat. The sliding seat has an arc-shaped guide rail along the sliding direction of the mounting seat, and an arc-shaped rack with the same arc-shaped track as the arc-shaped guide rail. The swing seat has a turntable assembly that can engage with the arc-shaped rack. The swing seat has a fixed sleeve with a rotating sleeve inside. The rotating sleeve has a dressing head, a drive groove on its outer wall, and a sliding ring that slides elastically on the fixed sleeve. The sliding ring is hinged to the turntable with a connecting rod, and has a lever that cooperates with the drive groove to drive the dressing head to rotate or lock it. The sliding seat has a locking device to lock or unlock the turntable. The device can dress the arc surface and the chamfer of the grinding wheel, and can prevent a part of the dressing head that contacts the grinding wheel from being continuously worn out.

[0004] In this technical solution, the dressing head is driven to rotate, adjusting the contact surface between the dressing head and the grinding wheel, preventing a part of the dressing head from being continuously worn out. However, during the grinding process, a large amount of debris will be generated, some of which will be stuck in the strip-shaped groove, the sliding groove, and the arc-shaped worm gear rack and worm, making it difficult for the dressing head to rotate, and thus further improvement is needed.

[0018] (III) Advantages

[0019] Compared with the prior art, the grinding wheel dressing device for a grinding machine has the following advantages:

[0020] 1. The grinding wheel dressing device for a grinding machine prevents debris generated during grinding wheel grinding from entering between the self-rotation transmission member and the self-rotation driving member, and prevents debris from entering the inside of the gear set between the adjustment knob and the right support shaft and from entering between the friction disc and the left support shaft, so that the adjustment of the angle of the diamond pen and the driving of the self-rotation of the diamond pen can be stably performed.

[0021] 2. The grinding wheel dressing device for a grinding machine drives the fixed cylinder, the cladding ring, and the trapezoidal block two to move upward along the guide strip by rotating the threaded rod driven by the motor, the trapezoidal block two first pushes the trapezoidal block one to move upward, the sleeve and the extension ring move downward under the elastic action of the spring one when the trapezoidal block one is separated from the guide strip, so that the trapezoidal block one slides along the inclined surface at the top of the trapezoidal block two, and the sleeve and the extension ring are rotated for the first time, then the fixed cylinder, the cladding ring, and the trapezoidal block two move downward along the guide strip by reversing the rotation of the threaded rod driven by the motor, the trapezoidal block one moves downward synchronously with the trapezoidal block two, then the guide strip abuts against the inclined surface of the trapezoidal block one, the trapezoidal block one slides at the top of the guide strip after the trapezoidal block two is separated from the trapezoidal block one, so that the sleeve and the extension ring are rotated for the second time, until the guide strip is inserted into the linear slot one and abuts against the bottom of the extension ring, the sleeve and the extension ring are rotated for one-eighth of a circle around their axes after the above two rotations, the rotating shaft, the socket, and the diamond pen rotate synchronously with the sleeve because the sleeve is slidably connected to the convex strip, so that the angle of self-rotation of the diamond pen is controllable each time, and the self-rotation transmission member and the self-rotation driving member are arranged along the same straight line, so that the structure is compact and space-saving.

[0022] 3. The grinding wheel dressing device for a grinding machine continues to move downward along the guide strip by the fixed cylinder and the cladding ring, the fixed cylinder abuts against the top of the sliding disc and pushes the sliding disc to move downward, the slide bead slides along the guide groove during the downward movement of the sliding disc with the pull rod, the slide bead drives the rotating cylinder to rotate when it slides along the upper half of the guide groove, the rotating ring is pressed against the slide post during the rotation of the rotating ring, so that the slide block slides along the mounting groove, the arc-shaped plate is gathered to the middle, the embedded strip is inserted between the limiting strips, and the rotation of the blocking ring, the socket, and the diamond pen is inhibited, so that the diamond pen is prevented from being rotated by mistake during the grinding of the grinding wheel, and the contact surface between the diamond pen and the grinding wheel is kept stable during the grinding.

[0023] 4. The grinding machine uses a grinding wheel dressing device, which squeezes the lubricating oil in the bottom of the cylindrical shell during the downward sliding of the sliding disc, causing the lubricating oil to pass through the through hole and the slide rod and spray upward to lubricate the internal structure of the shell; thus, the adjustment of the diamond pen's rotation is smoother, ensuring the reliability of the adjustment process.

[0046] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0047] Please refer to Figures 1-5 A grinding wheel dressing device for a grinding machine comprises a U-shaped seat 100, a cladding shell 200 rotatably connected between the two ends of the U-shaped seat 100, a mounting shaft seat 300 rotatably connected at the top end of the cladding shell 200, a diamond pen 400 inserted into the top end of the mounting shaft seat 300, an angle adjusting member 500 arranged between the cladding shell 200 and the U-shaped seat 100, and the cladding shell 200 is driven to rotate relative to the U-shaped seat 100 through the angle adjusting member 500, so as to adjust the inclination angle of the diamond pen 400. A rotation transmission member 600 is slidably connected to the outside of the mounting shaft seat 300, and the mounting shaft seat 300 can be driven to rotate synchronously when the rotation transmission member 600 rotates. During the rotation of the mounting shaft seat 300 and the rotation transmission member 600, the rotation transmission member 600 can slide relative to the mounting shaft seat 300. A rotation driving member 700 is arranged below the rotation transmission member 600, and the rotation transmission member 600 is intermittently driven to rotate through the up-and-down reciprocating movement of the rotation driving member 700, so as to continuously rotate the diamond pen 400 and adjust the contact position of the diamond pen 400 with the grinding wheel.

[0048] A rotation limiting member 800 is sleeved on the outside of the mounting shaft seat 300, and a limiting driving member 900 is arranged between the bottom of the rotation limiting member 800 and the rotation driving member 700. After the rotation driving member 700 is separated from the rotation transmission member 600, the rotation driving member 700 continues to move downward, pushes the limiting driving member 900, and drives the rotation limiting member 800 to be clamped on the outside of the mounting shaft seat 300 through the limiting driving member 900, so as to inhibit the rotation of the mounting shaft seat 300 and keep the diamond pen 400 at the current position.

[0049] Please refer to Figure 4 The cladding shell 200 comprises a cylindrical shell 201 rotatably connected between the two ends of the U-shaped seat 100, an annular seat 202 and a limiting ring 203 fixedly installed on the inner wall of the upper half of the cylindrical shell 201, the annular seat 202 being located on the upper side of the limiting ring 203, an installation slot 207 being arrayed and penetratingly formed on the annular seat 202, and the installation slot 207 being arranged along the radial direction of the annular seat 202. A plurality of fixed plates 204 are arrayed and fixed on the inner wall of the cylindrical shell 201, each fixed plate 204 being fixedly installed with a guide strip 205 at the end away from the inner wall of the cylindrical shell 201, and each fixed plate 204 being fixedly installed with a bracket 206 at the bottom of the end close to the inner wall of the cylindrical shell 201. In this embodiment, the number of the fixed plates 204 is four.

[0050] Please refer to Figures 5-6 The mounting shaft seat 300 comprises a socket 301, the diamond pen 400 is inserted on top of the socket 301, and a fastening screw 305 is threadedly connected on the circumferential surface of the socket 301 and is attached to the surface of the diamond pen 400. Thus, the diamond pen 400 can be detachably mounted on the socket 301, and the diamond pen 400 is convenient to replace.

[0051] The socket 301 is attached to the top of the cladding shell 200, and a rotating shaft 302 is fixedly mounted at the bottom of the socket 301 and is rotatably connected at the center of the top of the cladding shell 200. A retaining ring 303 is fixedly mounted on the circumferential surface of the rotating shaft 302 and is attached to the top wall of the cladding shell 200. Thus, through the limiting action of the socket 301 and the retaining ring 303, the sliding of the rotating shaft 302 relative to the cladding shell 200 in the vertical direction is inhibited, and the rotating shaft 302 can only rotate relative to the cladding shell 200. A convex strip 304 is fixedly mounted on the circumferential surface of the rotating shaft 302 at the lower side of the retaining ring 303, and the convex strip 304 is parallel to the axis of the rotating shaft 302.

[0052] Please refer to Figures 7-8 The angle adjusting member 500 comprises a right supporting shaft 501 and a left supporting shaft 502, and the right supporting shaft 501 and the left supporting shaft 502 are perpendicular to the surface of the cylindrical shell 201. The right supporting shaft 501 and the left supporting shaft 502 are fixedly mounted on the left side and the right side of the cladding shell 200, respectively, and are rotatably connected at the two ends of the U-shaped seat 100, respectively.

[0053] A right retaining cover 503 is fixedly mounted on the right side of the U-shaped seat 100, and an adjusting knob 504 is rotatably connected on the right retaining cover 503. A gear set is connected between the adjusting knob 504 and the right supporting shaft 501. In this embodiment, the gear set comprises a gear one 505 and a gear two 506. The gear one 505 is fixedly mounted on the right end of the right supporting shaft 501, and the gear two 506 is fixedly mounted on the left end of the adjusting knob 504. The gear one 505 and the gear two 506 are meshed with each other. By screwing the adjusting knob 504, the gear two 506 is driven to rotate, the gear one 505 and the right supporting shaft 501 are driven to rotate, the cladding shell 200 is driven to deflect relative to the U-shaped seat 100, and the inclination angle of the diamond pen 400 is adjusted. An angle scale is provided on the circumferential surface of the right supporting shaft 501, which facilitates the adjustment of the inclination angle of the diamond pen 400. Specifically, the gear set is located inside the right retaining cover 503, which prevents the debris from being stuck in the gear set during the grinding process.

[0054] The left side of the U-shaped seat 100 is fixedly provided with a left cover 507, and a horizontal rod 508 is fixedly arranged on the inner wall of the left cover 507. A friction disc 509 is slidably connected to the horizontal rod 508, and a bolt 510 is rotatably connected to the left side of the friction disc 509. The bolt 510 is threadedly connected to the left cover 507, and the friction disc 509 is attached to the left end of the left supporting shaft 502. The horizontal rod 508 guides the movement path of the friction disc 509 and prevents the friction disc 509 from rotating with the bolt 510. By screwing the bolt 510, the friction disc 509 is tightly attached to the surface of the left supporting shaft 502, the rotation of the cladding shell 200 is prevented, and the diamond pen 400 is kept at the current inclination angle.

[0055] Referring to Figures 5-6 and Figure 9 The self-rotation transmission member 600 comprises a sleeve 601, an extension ring 602 is fixedly arranged on the outer wall of the top end of the sleeve 601, a sliding groove 603 is formed in the inner wall of the sleeve 601, the sleeve 601 is sleeved on the outer side of the rotating shaft 302, and the convex strip 304 is slidably connected to the sliding groove 603. Thus, when the sleeve 601 rotates, the rotating shaft 302 can be driven to rotate synchronously by the convex strip 304, and in this process, the sleeve 601 can slide relative to the rotating shaft 302.

[0056] Eight trapezoidal blocks one 604 are fixedly arranged on the outer wall of the sleeve 601, the trapezoidal blocks one 604 are attached to the bottom of the extension ring 602, and a linear slot one 605 is formed between two adjacent trapezoidal blocks one 604. The trapezoidal blocks one 604 are slidably connected to the guide strip 205 through the linear slot one 605, and a spring one 606 is fixedly arranged between the extension ring 602 and the blocking ring 303. The elasticity of the spring one 606 makes the sleeve 601 have a downward movement tendency, so that the guide strip 205 is attached to the bottom of the extension ring 602 after the self-rotation driving member 700 is separated from the self-rotation transmission member 600.

[0057] Referring to Figures 9-10 The self-rotation driving member 700 comprises a motor 701 fixedly arranged at the bottom of the cladding shell 200, a threaded rod 702 connected to the top output end of the motor 701, a fixed cylinder 703 threadedly connected to the threaded rod 702, a cladding ring 704 fixedly arranged on the top end outer wall of the fixed cylinder 703, and the inner diameter of the cladding ring 704 is equal to the outer diameter of the sleeve 601. Four trapezoidal blocks two 705 are fixedly arranged on the top of the cladding ring 704, four linear slots two 706 are arrayed on the circumferential surface of the cladding ring 704, the linear slots two 706 penetrate through the top of the trapezoidal blocks two 705, and the cladding ring 704 is slidably connected to the guide strip 205 through the linear slots two 706. The trapezoidal blocks two 705 and the trapezoidal blocks one 604 are both right-angled trapezoidal, and the inclined surfaces of the trapezoidal blocks two 705 and the cladding ring 704 are opposite.

[0058] The fixed cylinder 703, the covering ring 704 and the trapezoidal block two 705 are driven to move upward or downward by the motor 701 driving the threaded rod 702 to rotate under the guidance of the guide strip 205. In the process of moving upward of the fixed cylinder 703, the covering ring 704 and the trapezoidal block two 705, the trapezoidal block two 705 abuts against the bottom of the trapezoidal block one 604 and pushes the sleeve 601, the extension ring 602 and the trapezoidal block one 604 to move upward along the guide strip 205, and the spring one 606 is compressed. When the lowest point of the trapezoidal block one 604 moves to the upper side of the top end of the guide strip 205, the trapezoidal block one 604 slides along the inclined surface of the top of the trapezoidal block two 705, so that the sleeve 601, the extension ring 602 and the trapezoidal block one 604 rotate around the axis thereof.

[0059] Then, the motor 701 drives the threaded rod 702 to rotate reversely, so that the fixed cylinder 703 and the covering ring 704 move downward, and the sleeve 601 and the extension ring 602 move downward following the trapezoidal block two 705 under the elastic action of the spring one 606. Then, the guide strip 205 abuts against the inclined surface of the trapezoidal block one 604, and the trapezoidal block two 705 slides downward relative to the trapezoidal block one 604. When the trapezoidal block two 705 is separated from the trapezoidal block one 604, the extension ring 602 continues to move downward under the elastic driving of the spring one 606, the trapezoidal block one 604 slides on the top end of the guide strip 205 until the guide strip 205 is inserted into the linear slot one 605 and the extension ring 602 is attached to the inside of the extension ring 602. Thus, after one reciprocating motion of the fixed cylinder 703, the covering ring 704 and the trapezoidal block two 705, the sleeve 601, the extension ring 602 and the sliding groove 603 rotate one-eighth of a circle.

[0060] Please refer to Figures 11-12 After the rotation driving member 700 is separated from the rotation transmission member 600, only the elasticity of the spring one 606 makes the extension ring 602 attached to the top of the guide strip 205, and under the vibration action, the sleeve 601 and the extension ring 602 are easily shaken up and down in the inside of the covering shell 200. If the trapezoidal block one 604 is separated from the guide strip 205 in the vibration process, when the trapezoidal block one 604 is separated from the guide strip 205 again, the trapezoidal block one 604 is easily misrotated, so that the contact position of the diamond pen 400 with the grinding wheel changes outside the predetermined value in the process of grinding the grinding wheel. Thus, after the diamond pen 400 rotates, the mounting shaft seat 300 is limited by the rotation limiting member 800, so as to prevent the mounting shaft seat 300 from misrotating.

[0061] The rotation limiting piece 800 comprises a rotating ring 801 rotatably connected inside the cylindrical shell 201, the rotating ring 801 is located between the annular seat 202 and the limiting ring 203, and the surface of the rotating ring 801 is arrayed and provided with inclined grooves 802, the sliding block 803 is slidingly connected in the mounting groove 207, the sliding column 804 is fixedly installed at the bottom of the sliding block 803, the sliding column 804 corresponds to the inclined groove 802 in a one-to-one manner, and the sliding column 804 is slidingly connected in the inclined groove 802, and the arc-shaped plate 805 is fixedly installed at the bottom end of the sliding column 804. When the rotating ring 801 rotates, the rotating ring 801 is located at the side wall of the inclined groove 802 and extrudes the sliding column 804, so as to drive the sliding block 803 to slide along the mounting groove 207, so that the arc-shaped plate 805 is close to the containing pipe 806.

[0062] The containing pipe 806 is fixedly installed on the circumferential surface of the blocking ring 303, the limiting strips 807 are arrayed and fixed on the outer wall of the containing pipe 806, the inlaid strips 808 are arrayed and fixed on the inner side of the arc-shaped plate 805, and the inlaid strips 808 are inserted between the adjacent two limiting strips 807. Therefore, when the four arc-shaped plates 805 gather to the middle part, the inlaid strips 808 are inserted between the limiting strips 807, the rotation of the blocking ring 303 and the socket 301 is inhibited, and the misrotation of the diamond pen 400 in the grinding process of the grinding wheel is prevented.

When the rotating barrel 901 rotates, the rotating ring 801 rotates synchronously.

[0065] The sliding disc 904 is fixed with a slide rod 907 at the top, the slide rod 907 is slidingly connected through the holder 206, the slide rod 907 is fixedly installed with a ring-shaped cap 908 at the top end, and the ring-shaped cap 908 is fixedly installed with a spring 909 between the holder 206.

[0067] In use, the motor 701 drives the threaded rod 702 to rotate, drives the fixed cylinder 703, the cladding ring 704 and the trapezoidal block 705 to move upwards along the guide strip 205, the trapezoidal block 705 first pushes the trapezoidal block 604 to move upwards, when the trapezoidal block 604 is separated from the guide strip 205, the sleeve 601 and the extension ring 602 move downwards under the elastic action of the spring 606, so that the trapezoidal block 604 slides along the inclined surface at the top of the trapezoidal block 705, so that the sleeve 601 and the extension ring 602 are rotated for the first time;

[0068] Then, the motor 701 drives the threaded rod 702 to rotate reversely, so that the fixed cylinder 703, the cladding ring 704 and the trapezoidal block 705 move downwards along the guide strip 205, the trapezoidal block 604 moves downwards synchronously with the trapezoidal block 705, then the guide strip 205 abuts against the inclined surface of the trapezoidal block 604, after the trapezoidal block 705 is separated from the trapezoidal block 604, the trapezoidal block 604 is attached to the top of the guide strip 205 and slides, so that the sleeve 601 and the extension ring 602 are rotated for the second time, until the guide strip 205 is inserted into the linear slot 605 and is attached to the bottom of the extension ring 602; after the sleeve 601 and the extension ring 602 are rotated for the above two times, they are rotated by one eighth of a circle around the axis; since the sleeve 601 is slidingly connected to the convex strip 304, the rotating shaft 302, the socket 301 and the diamond pen 400 rotate synchronously with the sleeve 601;

[0069] Afterwards, the fixing cylinder 703 and the covering ring 704 continue to move downwards along the guide strip 205, the fixing cylinder 703 is attached to the top of the sliding disc 904 and pushes the sliding disc 904 to move downwards, the pull rod 905 follows the sliding disc 904 to move downwards, the sliding bead 906 slides along the guide groove 903, and when the sliding bead 906 slides along the upper half of the guide groove 903, the rotating cylinder 901 is driven to rotate, thereby driving the rotating ring 801 to rotate;

[0070] During the rotation of the rotating ring 801, the rotating ring 801 is located at the side wall of the inclined groove 802 to extrude the sliding column 804, thereby driving the sliding block 803 to slide along the mounting groove 207, the arc-shaped plate 805 is gathered to the middle part, and the batten 808 is inserted between the limiting strips 807, thereby inhibiting the rotation of the stop ring 303, the socket 301 and the diamond pen 400;
