Grinding wheel grinding tool and grinding method

Abstract

The invention relates to the technical field of grinding wheel grinding devices, in particular to a grinding wheel grinding tool and a grinding method. Comprising a base, a transmission mechanism, a first polishing block and a second polishing block. The first grinding block and the second grinding block are arranged on the base in a sliding mode and are oppositely arranged so that the gap between the first grinding block and the second grinding block can be adjusted. The transmission mechanism is in transmission connection with the first grinding block and the second grinding block so that the transmission mechanism can drive the first grinding block and the second grinding block to move relatively. When the grinding wheel polishing tool is used, the edge of a grinding wheel is moved to the position between the first polishing block and the second polishing block, so that the grinding wheel is polished to the preset thickness. In the polishing process, due to the fact that the two sides of the grinding wheel are polished at the same time, the two sides of the grinding wheel are both subjected to thrust perpendicular to the radius direction, and the two forces are opposite. Therefore, the two opposite pushing forces offset each other, and the grinding wheel is prevented from being broken due to the fact that the grinding wheel is subjected to single-side pushing force. And therefore, the grinding wheel can be ground to be thinner.

Description

Technical Field

[0001] The invention relates to the technical field of grinding wheel grinding devices, and in particular to a grinding wheel grinding tool and a grinding method. Background Art

[0002] In the processing of some workpieces, it is necessary to process grooves on their surfaces. At this time, a grinding wheel can be used for grinding. Specifically, the thickness of the grinding wheel can be first ground to the same as the width of the groove, and then the grinding wheel can be used to grind and form grooves on the surface of the workpiece. For some narrow grooves, the thickness after grinding by the grinding wheel is also very thin. As the grinding wheel gradually becomes thinner, the strength of the grinding wheel gradually decreases. However, the grinding of the grinding wheel in the prior art is to grind one side of the grinding wheel first, and then grind the other side. In other words, during the grinding process, the grinding wheel is always subjected to lateral extrusion force on one side. When the grinding wheel is ground to a very thin state, the force on one side can easily cause the grinding wheel to collapse. Therefore, the thickness of the grinding wheel after grinding in the prior art is still relatively thick, which further makes the width of the groove processed by the grinding wheel wider. It cannot adapt to some processing conditions with extremely narrow groove widths. Summary of the invention

[0003] The object of the present invention is to provide a grinding wheel grinding tool and a grinding method, which can grind from both sides of the grinding wheel at the same time to avoid the grinding wheel from being damaged due to unilateral force.

[0004] The embodiments of the present invention are implemented by the following technical solutions:

[0005] A grinding wheel grinding tool comprises a base, a transmission mechanism, a first grinding block and a second grinding block; the first grinding block and the second grinding block are slidably arranged on the base and are arranged relative to each other so that the gap between them is adjustable; the transmission mechanism is transmission-connected to the first grinding block and the second grinding block so that the transmission mechanism drives the first grinding block and the second grinding block to move relative to each other.

[0006] Furthermore, the transmission mechanism includes a screw; both ends of the screw are provided with external threads and the spiral directions of the external threads at both ends are opposite; the screw is rotatably penetrated through the base; the first grinding block and the second grinding block are respectively connected to one end of the screw, so that the rotation of the screw can drive the first grinding block and the second grinding block to approach or move away from each other.

[0007] Furthermore, an elastic member is provided between the first grinding block and the second grinding block, so that the first grinding block and the second grinding block can be pushed apart from each other or pulled tight against each other.

[0008] Furthermore, the first grinding block and the second grinding block are both provided with plug-in holes, and a grinding head is provided in each of the plug-in holes; a plug-in rod is provided at one end of the grinding head; and the plug-in rod is plugged into the plug-in hole.

[0009] Furthermore, the first grinding block and the second grinding block are both provided with locking holes; the locking holes are arranged perpendicular to the plug-in holes and are connected to the plug-in holes; and the locking holes are also provided with locking pins.

[0010] Furthermore, it also includes a thickness detection mechanism; the thickness detection mechanism includes two micrometers arranged opposite to each other; the heads of the two micrometers are arranged opposite to each other and both are matched with the grinding head so that the part of the grinding wheel being ground passes through the head during rotation.

[0011] Furthermore, the dial gauge head is provided with a ball.

[0012] Furthermore, one end of the screw rod is cooperated with a driving motor, so that the driving motor drives the screw rod to rotate.

[0013] Furthermore, the grinding head is configured to be spherical.

[0014] A grinding wheel grinding method is used in conjunction with the above-mentioned grinding wheel grinding tooling; the grinding method comprises: moving the outer edge of the grinding wheel to between two grinding heads for grinding; a thickness detection mechanism detects the thickness after grinding by the grinding wheel; a driving motor drives the two grinding heads to gradually approach each other until the thickness after grinding by the grinding wheel reaches a preset value; finally, feeding along the radial direction of the grinding wheel so that the amount of grinding along the radial direction of the grinding wheel reaches a preset value.

[0015] The technical solution of the embodiment of the present invention has at least the following advantages and beneficial effects:

[0016] When the grinding wheel grinding tool of the present invention is used, the edge of the grinding wheel is moved between the first grinding block and the second grinding block, so that the grinding wheel is ground to a preset thickness. During the grinding process, since both sides of the grinding wheel are ground at the same time, both sides of the grinding wheel are subjected to thrusts perpendicular to the radial direction and the two forces are opposite. This makes the two relative thrusts cancel each other out, preventing the grinding wheel from being damaged by a unilateral pushing force. In turn, the grinding wheel can be ground to a thinner thickness.

[0017] The threads on both sides of the screw rod cooperate with the first grinding block and the second grinding block, so that when the rod rotates, the first grinding block and the second grinding block move toward or away from each other, thereby achieving the effect of advancing and retreating. At the same time, the advance and retreat of the first grinding block and the second grinding block are also synchronized, avoiding uneven force on both sides of the grinding wheel caused by uneven advance and retreat. If the first grinding block and the second grinding block are only connected to the screw rod through threads, there will be a gap between the threads and the screw rod, and the distance between the first grinding block and the second grinding block will have a slight jump. The first grinding block and the second grinding block can be tightened or pushed outward by setting an elastic member. This makes the threads of the first grinding block and the second grinding block fit closely to the threads of the screw rod, thereby stabilizing the distance between the first grinding block and the second grinding block. It also further ensures that the size after grinding with the grinding wheel is more precise.

[0018] The thickness of the grinding wheel after grinding can be calculated by the readings of the two micrometers, and then the first grinding block and the second grinding block are automatically tightened to make the grinding wheel reach the predetermined thickness. The grinding head is set in a spherical shape, so that when the grinding wheel feeds along the radial direction, the grinding wheel is gradually ground by the curved grinding head until it moves between the two grinding heads and is ground to the predetermined thickness.

[0026] like Figure 1-6As shown, the present invention provides a grinding tool for grinding a grinding wheel 12, including a base 1, a transmission mechanism, a first grinding block 2 and a second grinding block 3. The first grinding block 2 and the second grinding block 3 are slidably arranged on the base 1 and are arranged relative to each other so that the gap between them is adjustable. Figure 2 As shown, the sliding parts of the first grinding block 2 and the second grinding block 3 are just embedded in the slide groove of the base 1, so that the first grinding block 2 and the second grinding block 3 can slide relative to the base 1. The tighter the fit between the slide groove and the first grinding block 2 and the second grinding block 3, the better the gap between the first grinding block 2 and the second grinding block 3 can be guaranteed, thereby ensuring that the size of the grinding wheel 12 after grinding is more accurate.

[0027] The transmission mechanism is connected to the first grinding block 2 and the second grinding block 3 so that the transmission mechanism drives the first grinding block 2 and the second grinding block 3 to move relative to each other. The transmission mechanism includes a screw 4. Figure 3 and Figure 4 As shown, both ends of the screw rod 4 are provided with external threads and the spiral directions of the external threads at both ends are opposite. The screw rod 4 is rotatably arranged in the base 1. The first grinding block 2 and the second grinding block 3 are respectively connected to one end of the screw rod 4, so that the rotation of the screw rod 4 can drive the first grinding block 2 and the second grinding block 3 to move closer to or away from each other.

[0028] When the grinding wheel 12 of the present invention is used, the edge of the grinding wheel 12 is moved between the first grinding block 2 and the second grinding block 3, so that the grinding wheel 12 is ground to a preset thickness. During the grinding process, since both sides of the grinding wheel 12 are ground at the same time, both sides of the grinding wheel 12 are subjected to thrusts perpendicular to the radial direction and the two forces are opposite. This makes the two relative thrusts cancel each other out, preventing the grinding wheel 12 from being damaged by a unilateral pushing force. This allows the grinding wheel 12 to be ground to a thinner thickness.

[0029] The threads on both sides of the screw rod 4 are matched with the first grinding block 2 and the second grinding block 3, so that when the rod rotates, the first grinding block 2 and the second grinding block 3 move toward or away from each other, thereby achieving the effect of advancing and retreating. At the same time, the first grinding block 2 and the second grinding block 3 are also advanced and retreated synchronously, avoiding uneven force on both sides of the grinding wheel 12 caused by uneven advancement and retreat.

[0030] In this embodiment, an elastic member 5 is further provided between the first grinding block 2 and the second grinding block 3 so that the first grinding block 2 and the second grinding block 3 are pushed apart from each other or pulled tight against each other. Figure 3 As shown, the elastic member 5 can be a tension spring or a compression spring. The elastic member 5 can push the first grinding block 2 and the second grinding block 3 to the sides, or pull them to the middle. In both cases, the first grinding block 2 and the second grinding block 3 will fit tightly with the thread of the screw rod 4.

[0031] In actual use, if the first grinding block 2 and the second grinding block 3 are connected to the screw rod 4 only by threads, there will be a gap between the threads and the screw rod 4, so that the distance between the first grinding block 2 and the second grinding block 3 will slightly jump. The elastic member 5 is provided to tighten or push the first grinding block 2 and the second grinding block 3 outward. This makes the threads of the first grinding block 2 and the second grinding block 3 closely fit the threads of the screw rod 4, so that the distance between the first grinding block 2 and the second grinding block 3 is stable. It also further ensures that the size of the grinding wheel 12 after grinding is more accurate.

[0032] In this embodiment, the first grinding block 2 and the second grinding block 3 are both provided with a plug hole 8 and a grinding head 6 is provided in each plug hole 8. Figure 3 As shown, a plug-in rod 7 is provided at one end of the grinding head 6. The grinding head 6 is used to grind the grinding wheel 12, and the plug-in rod 7 is used to install the grinding head 6. The plug-in rod 7 is plugged into the plug-in hole 8, so that the grinding head 6 is connected to the first grinding block 2 or the second grinding block 3. This allows the grinding head 6 to be quickly replaced.

[0033] In this embodiment, the first grinding block 2 and the second grinding block 3 are both provided with locking holes 9. Figure 2 As shown, the locking hole 9 is arranged perpendicular to the plug-in hole 8 and is connected to the plug-in hole 8. A locking pin is also arranged inside the locking hole 9. After the plug-in rod 7 is inserted into the plug-in hole 8, the locking pin is inserted into the locking hole 9. The locking pin can be a screw or an ordinary plug pin. If the locking pin is a screw, tightening it can fix the position of the plug-in rod 7 relative to the plug-in hole 8, thereby allowing the grinding head 6 to be stably installed in the plug-in hole 8. If the locking pin is a pin, the plug-in rod 7 needs to be provided with a pin hole so that the pin hole is opposite to the locking hole after the plug-in rod 7 is inserted. Inserting the pin into the pin hole can fix the position of the plug-in rod 7 relative to the plug-in hole 8.

[0034] In this embodiment, a thickness detection mechanism is also included. The thickness detection mechanism includes two micrometers 10 arranged opposite to each other. Figure 6 As shown, the dial heads of the two micrometers 10 are arranged opposite to each other and are arranged in cooperation with the grinding head 6 so that the grinding part of the grinding wheel 12 passes through the dial heads during rotation. That is, the distance between the dial head of the micrometer 10 and the rotation center of the grinding wheel 12 is the same as the distance between the grinding head 6 and the rotation center of the editorial.

[0035] In practice, the two gauge heads are butted and both micrometers 10 have readings, and these two readings are recorded as initial values. When the grinding wheel 12 passes between the two, the readings of both become larger and the sum of the values ​​of the increased readings of both is recorded as the thickness of the grinding wheel 12. In this way, the thickness change of the grinding wheel 12 can be recorded in real time, and then the grinding is stopped in time when the grinding reaches the required thickness. In order to better realize automation, the micrometer 10 can be selected electronically, and then an electrical signal can be output, thereby realizing automatic control. In addition, the two sides should be thinned synchronously during the grinding process of the grinding wheel 12. The two micrometers 10 monitor one side each to observe the thinning of the two sides in real time. If the thinning speed of the two sides is different, it may cause uneven force on both sides and collapse. At this time, the machine can be stopped in time for maintenance. Since the two gauge heads are butted against each other in the initial state, the grinding wheel 12 is not convenient to be sent between the two gauge heads. Therefore, when the grinding wheel 12 enters between the two gauge heads, the two gauge heads can be manually pressed down to leave a gap for the grinding wheel 12 to enter.

[0036] In the present embodiment, the dial head of the micrometer 10 is provided with a ball bearing, which causes the dial head to roll and rub against the grinding wheel 12, thereby prolonging the service life.

[0037] In this embodiment, a drive motor 11 is provided at one end of the screw rod 4 so that the drive motor 11 drives the screw rod 4 to rotate. The drive motor 11 can adjust the distance between the two grinding heads 6, and further adjust the thickness after grinding by the grinding wheel 12.

[0038] In this embodiment, the grinding head 6 is configured to be spherical. Figure 6 As shown, the grinding head 6 is configured to be spherical, so that when the grinding wheel 12 feeds along the radial direction, the grinding wheel 12 is gradually ground by the curved grinding head 6 until it moves between the two grinding heads 6 and is ground to a predetermined thickness.

[0039] The present invention also provides a grinding method for a grinding wheel 12, which is used in conjunction with the above-mentioned grinding tool for grinding the grinding wheel 12. The grinding method is: the outer edge of the grinding wheel 12 is moved between the two grinding heads 6 for grinding. The thickness detection mechanism detects the thickness of the grinding wheel 12 after grinding. The driving motor 11 drives the two grinding heads 6 to gradually approach until the thickness of the grinding wheel 12 after grinding reaches a preset value. Finally, the cutting is performed along the radial direction of the grinding wheel 12, so that the amount of grinding of the grinding wheel 12 along the radial direction reaches a preset value. This grinding method makes the grinding process of the grinding wheel 12 continuous, thereby improving the grinding efficiency.
