Description

Technical Field

[0001] The invention relates to the technical field of grinding wheel dressing, in particular to an angle adjustment device for a grinding wheel dresser used in a guide roller grinder. Background Art

[0002] In the machinery manufacturing industry, many precision machines are finished. Grinding wheels are an important component of grinding machines. They are usually used for grinding various mechanical parts. They are in the shape of a disc with a smooth surface and uniform thickness. A hole is opened in the center so that they can be installed on a high-speed rotating shaft. In the prior art, the edge of the grinding wheel is trimmed by a grinding wheel dresser. The vertical dresser is placed on the grinding machine disk and sucked. The fine-tuning screw is turned to adjust the center height of the machine tool grinding wheel so that the diamond tip and the center of the grinding wheel are on the same horizontal plane. After the working angle of the turntable required for trimming the truncated arc of the grinding wheel is met, the locking screw is tightened, and then the turntable is rotated so that the turntable drives the diamond cutter to rotate, thereby trimming the truncated arc of the grinding wheel.

[0003] However, it is inconvenient to quickly limit and adjust the rotation angle of the turntable when dressing the grinding wheel. If the rotation angle of the turntable is too large, the range of the diamond pen to dress the grinding wheel will exceed the required dressing range. If the rotation angle is too small, the dressing effect of the grinding wheel will be affected. At the same time, when dressing the grinding wheel, the thickness of the diamond pen at the edge of the grinding wheel is too long in a single dressing. The diamond pen will cause excessive pressure on the grinding wheel during the dressing process, resulting in uneven wear of the grinding wheel, which will affect the cutting performance and life of the grinding wheel and may even cause the grinding wheel to vibrate and make noise during the subsequent grinding process, resulting in low dressing accuracy.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1.

The movable plug plate is pulled and the rotating shaft is rotated 180 degrees clockwise, so that the diamond pen moves a certain distance away from the grinding wheel, and the movable seat is rotated to make the diamond pen dress and grind the edge of the grinding wheel. The limit pins are pulled counterclockwise one by one to make the diamond pen intermittently move toward the grinding wheel for a certain distance, so as to prevent the movable seat from driving the diamond pen to dress the grinding wheel directly, resulting in a large thickness of the edge of the grinding wheel dressed by the diamond pen in a single time, thereby preventing the diamond pen from causing excessive pressure on the grinding wheel, resulting in uneven wear of the grinding wheel, so as to improve the accuracy of dressing; 2.

During this process, the aqueous solution inside the arc connecting sleeve enters the water tank through the guide tube, or the solution inside the water tank flows into the arc connecting sleeve. Then, the angle between the arc clamping blocks at both ends of the arc connecting sleeve is adjusted by observing the scale lines at the edge of the turntable. The angle between the arc clamping blocks is the maximum rotation angle of the movable seat driven by the turntable. When the second screw is rotated, the dial will drive the T-shaped plug rod to move horizontally through the bayonet pin, so that the aqueous solution inside the piston cylinder enters the water tank or the aqueous solution in the water tank enters the piston cylinder. When the turntable is rotated, the solenoid valve is closed. At this time, the aqueous solution inside the arc connecting sleeve and the piston cylinder will lose flow space, so as to realize the fixation of the clamping block and the arc clamping block, so as to quickly and accurately control the rotation angle of the turntable, thereby further improving the accuracy of the diamond pen in dressing the grinding wheel.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention.

[0020] See also Figures 1 to 8 In an embodiment of the present invention, a grinding wheel dresser angle adjustment device for a guide roller grinder includes a base 1, a connecting plate 2 is installed on the top of the base 1, a turntable 3 is rotatably connected to the top of the connecting plate 2 through a bearing, a positioning seat 4 is installed on the top of the turntable 3, a movable seat 5 is slidably connected to the positioning seat 4, a diamond pen mounting seat 6 is slidably connected to the top of the movable seat 5, an equidistant dressing piece connected to the movable seat 5 is arranged on one side of the positioning seat 4, and a limited angle adjustment piece is arranged on the outer side of the turntable 3.

[0021] In this embodiment, the diamond pen is first installed on the diamond pen mounting seat 6 by bolts, the vertical dresser is placed on the grinding machine disk and sucked, the center height of the machine tool grinding wheel is adjusted so that the diamond pen tip and the grinding wheel center are on the same horizontal plane, and then the movable seat 5 is pushed to adjust the distance from the diamond pen tip to the center of the turntable 3 by moving the movable seat 5, and then the grinding wheel and the diamond pen tip are brought into contact with each other through the operation of the machine tool, and then the equidistant dresser is operated to move the diamond pen a distance to the side away from the grinding wheel, and then the angle limiting adjustment member is operated to limit the swing angle of the turntable 3 relative to the connecting disk 2, and then the grinding wheel is rotated through the operation of the machine tool, and the movable seat 5 is rotated at the same time so that the movable seat 5 moves along the connecting disk 2. The center of the circle of the disk 2 rotates. During this process, since the movable seat 5 is far away from the grinding wheel, the tip of the diamond pen only contacts the edges on both sides of the grinding wheel when the movable seat 5 drives the diamond pen to rotate. Then, the movable seat 5 drives the tip of the pen to move a distance toward the grinding wheel by operating the equidistant dressing piece. The movable seat 5 is rotated again to make the diamond pen grind and dress the thickness of the grinding wheel edge. Then, the equidistant dressing piece is operated again to make the movable seat 5 drive the tip of the pen to move a distance toward the grinding wheel. This can be repeated to achieve equal feeding distance of the movable seat 5 each time, thereby preventing the diamond pen from exerting excessive pressure on the grinding wheel due to excessive single dressing amount during the dressing process, resulting in uneven wear of the grinding wheel, thereby improving the dressing accuracy of the equipment for the grinding wheel.

[0022] Please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7The equidistant trimming piece includes a positioning indicator frame 805 installed on the top of the turntable 3 and located on both sides of the positioning seat 4, fixed columns 809 are installed on both sides of the movable seat 5, and a measuring ruler 802 is arranged on the fixed column 809. A U-shaped connecting rod 806 is installed on the top of the movable seat 5 away from the diamond pen mounting seat 6. The top of the U-shaped connecting rod 806 is rotatably connected to the second screw rod 815 through a bearing. A rectangular hole 808 located below the U-shaped connecting rod 806 is opened on the top of the movable seat 5 away from the diamond pen mounting seat 6. The second screw rod 815 extends to the inside of the rectangular hole 808. A clamping block 814 is movably sleeved on the second screw rod 815. The positioning seat A connecting plate 801 is installed at one end away from the rectangular hole 808, and a partition 810 is arranged on one side of the connecting plate 801. A first screw rod 803 penetrating the bottom of the movable seat 5 is rotatably connected to the partition 810 through a bearing. A hexagonal sleeve 807 located on the inner side of the movable seat 5 is sleeved on the first screw rod 803. A small transmission bevel gear 823 is installed at one end of the first screw rod 803 away from the hexagonal sleeve 807. A rotating shaft 817 is rotatably connected to one end of the connecting plate 801 away from the positioning seat 4. A large transmission bevel gear 818 meshing with the small transmission bevel gear 823 is arranged on the rotating shaft 817. The partition 810 is close to the small transmission bevel gear 823. A T-shaped baffle 824 is installed on one side of the gear 823, and a U-shaped baffle 819 is arranged on the rotating shaft 817, which is located on both sides of the large transmission bevel gear 818 and fits with one end of the T-shaped baffle 824. Ratchets 820 are fixed to both ends of the rotating shaft 817, and a movable plug plate 816 is inserted at the top of the connecting plate 801. The movable plug plate 816 is provided with a second return spring 822 connected to the top of the connecting plate 801, and a pawl 821 meshing with the ratchet 820 is arranged at the bottom end of the movable plug plate 816. The connection between the pawl 821 and the movable plug plate 816 is clamped with a first torsion spring 827 through a clamping slot. The rotating shaft 817 and the movable plug plate 816 are connected. A second torsion spring 828 is clamped at the connection of the connecting plate 801 through a slot, and a side connecting frame 804 is installed on the side of the connecting plate 801 away from the partition 810. Four limit pins 812 are inserted at one end of the side connecting frame 804, and a first return spring 813 connected to the side connecting frame 804 is arranged on the limit pins 812. The four limit pins 812 are equidistantly distributed in a semicircle along the center of the rotating shaft 817. A rotating disk 811 is arranged on the ratchet 820 at one end of the rotating shaft 817 close to the side connecting frame 804, and a trapezoidal block 826 is installed at the edge of the rotating disk 811, and a limiting groove 825 is opened on one side of the trapezoidal block 826.

[0023] In this embodiment, the distance from the diamond pen to the center of the turntable 3 is adjusted by sliding the movable seat 5 on the positioning seat 4, and then the distance from the diamond pen tip to the center of the turntable 3 is clearly measured by observing the position of the positioning indicator frame 805 corresponding to the measuring ruler 802, and then the second screw rod 815 is twisted, and the clamping block 814 is moved toward the hexagonal sleeve 807 by the rotation of the second screw rod 815, so that the bottom of the clamping block 814 is fitted with the top of the hexagonal sleeve 807, thereby realizing the connection between the movable seat 5 and the hexagonal sleeve 807, and the operation of the machine tool is used to make the diamond pen tip and the turntable 3 center. The tip of the diamond pen fits in with the center of the edge of the grinding wheel, then the movable plug plate 816 is pulled and the rotating shaft 817 is rotated 180 degrees clockwise. The large transmission bevel gear 818 drives the small transmission bevel gear 823 to rotate four circles through the rotation of the rotating shaft 817, so that the hexagonal sleeve 807 drives the movable seat 5 to move a certain distance away from the grinding wheel, thereby moving the diamond pen away from the grinding wheel. At the same time, the trapezoidal block 826 squeezes the limit pin 812 through its inclined surface, so that the rotating disc 811 rotates unimpeded with the rotating shaft 817. The movable plug plate 816 is loosened so that the pawl 821 meshes with the ratchet wheel 820 again under the elastic restoring force of the second return spring 822, and then the machine tool is started to rotate the grinding wheel, and then the movable seat 5 is rotated to make the diamond pen trim and grind the edge of the grinding wheel. In this process, the lower limit pin 812 is pulled, and the limit pin 812 is separated from the limit groove 825. The rotating disc 811 loses its limit and rotates forty-five degrees under the elastic restoring force of the second torsion spring 828, so that the large transmission bevel gear 818 drives the small The transmission bevel gear 823 rotates one circle to move the diamond pen toward the grinding wheel for a certain distance. In this way, the limit pins 812 are pulled counterclockwise one by one to make the diamond pen intermittently move toward the grinding wheel for a certain distance. When the trapezoidal block 826 returns to its initial state, the movable seat 5 drives the diamond pen to fit with the center of the edge of the grinding wheel again, so as to prevent the movable seat 5 from driving the diamond pen to directly trim the grinding wheel, causing the thickness of the grinding wheel edge to be trimmed by the diamond pen in a single time to be larger, thereby preventing the diamond pen from exerting excessive pressure on the grinding wheel, resulting in uneven wear of the grinding wheel, thereby improving the accuracy of trimming.

[0024] Please refer to Figure 1 , Figure 2 The zero scale line on the measuring ruler 802 is aligned with the vertical center axis of the positioning indicator frame 805, and the vertical center axis of the positioning indicator frame 805 is flush with the vertical center axis of the connecting disk 2.

[0025] In this embodiment, by setting this structure, the distance from the tip of the diamond pen to the center of the turntable 3 can be clearly obtained, so that the swing arc of the diamond pen can be quickly controlled, thereby improving the overall dressing efficiency of the equipment for the grinding wheel.

[0026] Please refer to Figure 4 A threaded hole matching the second screw rod 815 is provided on the inner side of the clamping block 814 , both sides of the clamping block 814 are in contact with the inner wall of the rectangular hole 808 , and an anti-slip pad is provided on the bottom of the clamping block 814 .

[0027] In this embodiment, by providing this structure, the clamping block 814 moves downward when the second screw rod 815 rotates, so that the clamping block 814 presses the hexagonal sleeve 807, thereby achieving synchronous movement of the movable seat 5 and the hexagonal sleeve 807.

[0028] Please refer to Figure 5 , Figure 6 , Figure 7 , the diameter of the small transmission bevel gear 823 is eight times the diameter of the large transmission bevel gear 818.

[0029] In this embodiment, this structure is provided to enable the rotating coupling 817 to rotate one hundred and eighty degrees when the small transmission bevel gear 823 rotates four circles, and then cooperates with the limiting of the trapezoidal block 826 by multiple limiting pins 812 to make the first screw rod 803 drive the hexagonal sleeve 807 to move the same distance when the rotating coupling 817 swings.

[0030] Please refer to Figure 5 , Figure 6 The limiting groove 825 is arranged on the side of the trapezoidal block 826 away from the inclined surface thereof, and one end of the limiting latch 812 close to the rotating disk 811 is rotatably connected with a ball through a bearing.

[0031] In this embodiment, this structure is provided to prevent the limit pin 812 from obstructing the rotating disk 811 when the rotating disk 811 rotates clockwise, and at the same time, the limit pin 812 limits the single rotation angle of the rotating disk 811 through the limit groove 825 when the rotating disk 811 rotates counterclockwise, and at the same time, the friction between the limit pin 812 and the trapezoidal block 826 is reduced.

[0032] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8The angle limiting adjustment member includes a positioning column 703 installed on the top of the connecting disk 2 and located on one side of the rotating disk 3, an arc-shaped connecting sleeve 706 is installed at the edge of the rotating disk 3, and arc-shaped plug rods 705 are inserted at both ends of the arc-shaped connecting sleeve 706. An arc-shaped blocking block 704 is installed at one end of the arc-shaped plug rod 705 away from the arc-shaped connecting sleeve 706. A scale line located above the arc-shaped blocking block 704 is provided at the edge of the rotating disk 3. A guide tube 714 that passes through the rotating disk 3 and is located above the positioning column 703 is provided on the outer wall of the arc-shaped connecting sleeve 706. The end of the guide tube 714 away from the arc-shaped connecting sleeve 706 is installed with an electromagnetic valve 702. The end of the electromagnetic valve 702 away from the guide tube 714 A water tank 701 is provided at the end, a dial plate 712 located above the U-shaped connecting rod 806 is installed on the top of the second screw rod 815, a latch pin 711 is provided on the top of the dial plate 712, a T-shaped plug rod 709 is provided on the latch pin 711, a guide groove 710 is provided at one end of the T-shaped plug rod 709, the T-shaped plug rod 709 is slidably connected to the outside of the latch pin 711 through the guide groove 710, a piston rod 713 is installed at the end of the T-shaped plug rod 709 away from the latch pin 711, a piston cylinder 708 connected to the movable seat 5 is provided on the outside of the piston rod 713, and a connecting hose 707 connected to the guide pipe 714 is installed at the end of the piston cylinder 708 away from the T-shaped plug rod 709.

[0033] In this embodiment, the arc plug rod 705 is pushed to move the arc plug rod 705 along the arc connecting sleeve 706. During this process, the aqueous solution inside the arc connecting sleeve 706 enters the water tank 701 through the guide tube 714, or the solution inside the water tank 701 flows into the arc connecting sleeve 706. Then, the angle between the arc-shaped positioning blocks 704 at both ends of the arc connecting sleeve 706 is adjusted by observing the scale lines at the edge of the turntable 3. The angle between the arc-shaped positioning blocks 704 is the maximum rotation angle of the turntable 3 to drive the movable seat 5. When the second screw rod 815 rotates, When the dial plate 712 is turned, it will drive the T-shaped rod 709 to move horizontally back and forth through the latch pin 711, so that the aqueous solution inside the piston cylinder 708 enters the water tank 701 or the aqueous solution in the water tank 701 enters the piston cylinder 708. When the turntable 3 is rotated, the solenoid valve 702 is closed. At this time, the arc-shaped connecting sleeve 706 and the aqueous solution inside the piston cylinder 708 will lose the flow space, so as to realize the fixation of the clamping block 814 and the arc-shaped clamping block 704, so as to quickly and accurately control the rotation angle of the turntable 3, and further improve the accuracy of the diamond pen in dressing the grinding wheel.

[0034] Please refer to Figure 2 , Figure 8 The center of the arc-shaped connecting sleeve 706, the center of the arc-shaped plug rod 705, and the center of the rotating disk 3 are coaxial.

[0035] In this embodiment, by providing this structure, when the arc plug rod 705 moves along the arc connecting sleeve 706, the arc blocking block 704 rotates along the center of the turntable 3, further improving the accuracy of the arc blocking block 704 in limiting the angle of the turntable 3.

[0036] Please refer to Figure 3 , Figure 4 The center of the circle of the bayonet 711 and the center of the circle of the dial plate 712 are in a misaligned state, and the length of the piston cylinder 708 is equal to the distance from the bayonet 711 to the center of the circle of the dial plate 712.

[0037] In this embodiment, by providing this structure, the piston rod 713 can only move in the horizontal direction when the dial 712 rotates, and the stability of the movement of the T-shaped plug 709 is also improved.

[0038] Please refer to Figure 1 , Figure 8 A buffer protection pad is arranged on the outer side of the positioning column 703 , and a gap is left between the bottom of the arc-shaped positioning block 704 and the top of the connecting disk 2 .

[0039] In this embodiment, the arrangement is used to prevent the arc-shaped locking block 704 from colliding with the positioning column 703 with great force when the turntable 3 rotates, thereby preventing the positioning column 703 or the arc-shaped locking block 704 from being damaged. At the same time, it also prevents the arc-shaped locking block 704 from rubbing against the connecting disk 2 and the turntable 3 when rotating, thereby improving the smoothness of the rotation of the turntable 3 relative to the connecting disk 2.
