Description

Technical Field

[0001] This utility model relates to the field of abrasive technology, and in particular to a grinding wheel for a grinding machine. Background Technology

[0002] Abrasives are tools used for grinding, polishing, and grinding. They are widely used in machinery manufacturing and other metal processing industries, as well as in food processing, papermaking, and the processing of non-metallic materials such as ceramics, glass, stone, plastics, rubber, and wood.

[0003] Traditional grinding tools are generally equipment used for grinding the surface of workpieces. Most grinding equipment uses high-speed rotating grinding wheels for grinding. When grinding, the grinding wheel not only grinds the edges of the object, but also grinds the inner surface of grooves cut into the object. When grinding the inner surface of the groove, existing grinding equipment requires changing the size of the grinding wheel according to the depth of the groove, so as to grind the inner surface of the groove at different depths. This not only affects the grinding efficiency, but also has a certain impact on the grinding accuracy.

[0004] Chinese utility model patent application number CN202321962932.5 describes a grinding wheel with a threaded rod and a rotating plate. The threaded rod is rotated to drive a first connecting rod to adjust the rotating plate, thereby adjusting the height of the grinding wheel. This allows the grinding wheel to grind the inner surface of grooves of different depths on the object being polished, improving the efficiency and accuracy of polishing. However, when the above-mentioned grinding wheel is used to polish the inside of the groove, if the groove width is different, although the grinding wheel can move up and down to adjust the polishing depth, it is not easy for the grinding wheel to enter the deep part of the groove when polishing grooves narrower than the width of the groove, resulting in poor polishing effect for narrower grooves. Utility Model Content

[0005] The purpose of this invention is to provide a grinding wheel for a grinder, in order to solve the problem mentioned in the background art that the grinding wheel of the existing grinder is difficult to enter the depth of narrow grooves, resulting in poor grinding effect on narrow grooves.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a grinding wheel for a grinding machine, comprising a fixed shaft, a limiting plate fixedly sleeved on the outer circumferential surface of the fixed shaft, a plurality of grinding wheels sleeved on the outer circumferential surface of the fixed shaft along the axis of the fixed shaft, a fixing assembly provided on the fixed shaft, the plurality of grinding wheels being tightly abutted together in sequence, and the left side of the leftmost grinding wheel and the right side of the limiting plate being tightly abutted together;

[0007] The fixing component is used in conjunction with the limiting plate to fix multiple grinding wheels to the fixed shaft.

[0008] Preferably, the fixing assembly includes two sets of straight holes symmetrically formed on the outer circumferential surface of the fixing shaft. Two sets of push rods are symmetrically slidably connected within the two sets of straight holes via a third elastic element. The fixing assembly also includes two limiting holes symmetrically formed on the inner wall of the grinding wheel. The push rods can be inserted into the limiting holes. The top surface of the push rod is an inclined surface, and the inner top wall of the limiting hole is an inclined surface parallel to the top surface of the push rod. The top surface of the push rod is inclined away from the limiting plate. The fixing assembly also includes a transmission mechanism mounted on the fixing shaft. The transmission mechanism is used to push the two sets of push rods to slide towards each other. The fixing assembly also includes a mechanism for limiting the transmission mechanism to prevent further movement of the transmission mechanism. The limiting mechanism that drives the push rod to slide further includes a disassembly mechanism. The disassembly mechanism is used to release the limiting mechanism from restricting the transmission mechanism. The advantage of this design is that the transmission mechanism pushes the two sets of push rods to move in opposite directions until they are pressed tightly against the inner top wall of the upper limit hole on the inner side wall of multiple grinding wheels. Then, the limiting mechanism restricts the transmission mechanism, thus completing the fixing of multiple grinding wheels. The top surface of the push rod is inclined away from the limiting plate, so the push rod can cooperate with the limiting plate to improve the fixing firmness of the grinding wheel, ensuring that the grinding wheel can perform high-speed rotation grinding normally, thus improving the reliability of the grinding tool.

[0009] Preferably, the transmission mechanism includes a transverse hole at the center of the right end face of the fixed shaft along the axis of the fixed shaft. The ends of the two sets of straight holes that are close to each other are connected to the transverse hole. Multiple isosceles trapezoidal driving blocks are slidably connected in the transverse hole along the axis of the fixed shaft. The multiple driving blocks are fixedly connected together in sequence. The sides of the two sets of push rods that are close to each other are symmetrical inclined surfaces. The sides of the two sets of push rods that are close to each other are parallel to and fit against the inclined surfaces of the multiple driving blocks. A first elastic element is fixedly connected between the left side of the leftmost driving block and the left inner wall of the transverse hole. A push rod is fixedly connected to the right side of the rightmost driving block. When the push rod moves to the right, it can extend to the outside of the transverse hole. The advantage of this arrangement is that by simply pushing the push rod to the left, the multiple driving blocks can be moved to the left synchronously and the two sets of push rods can be pushed into the two sets of limiting holes respectively, which improves the efficiency of the fixing operation and thus improves the practicality of the mold.

[0010] Preferably, the limiting mechanism includes two insert rods symmetrically and movably inserted into the outer circumference of the fixed shaft via a second elastic element. The two insert rods have symmetrical inclined surfaces on their opposite sides. The limiting mechanism also includes a cylinder movably inserted into the right end of the fixed shaft. Two insertion holes are symmetrically opened on the inner wall of the cylinder. The two insert rods can be movably inserted into the two insertion holes respectively. The opposite ends of the two insertion holes both penetrate the outer wall of the cylinder. The advantage of this arrangement is that it is only necessary to align the two insertion holes with the two insert rods respectively, then put the cylinder on the right end of the fixed shaft, and with the inclined surface at the top of the insert rod, the two insert rods can be compressed into the inner wall of the cylinder and inserted into the fixed shaft. Subsequently, when the insert rods are aligned with the insertion holes, they can rebound under the elastic force of the second elastic element and insert into the insertion holes. This can conveniently complete the fixing of the cylinder, so that the cylinder can push the push rod to a position close to the left side, so that the push rod can be stably inserted into the limiting hole, thereby ensuring that the push rod can stably fix the grinding wheel on the fixed shaft and improving the reliability of the grinding wheel.

[0011] Preferably, the disassembly mechanism includes two pairs of vertical plates symmetrically fixedly connected to the outer circumference of the insert. Two round rods are symmetrically fixedly connected between the adjacent sides of the two pairs of vertical plates. The disassembly mechanism also includes two pry bars. The bottom end of each pry bar has an arc-shaped groove that can be fitted onto the round rod. Two pressure rods are symmetrically fixedly connected to the right sides of the two pry bars. The two pressure rods can extend into the insert hole. The advantage of this arrangement is that by fitting the groove onto the round rod and then bending the pry bar away from the fixed axis with the round rod as the axis, the pressure rod can penetrate the insert hole and press the insert into the fixed axis. This releases the limiting fixation of the insert. Furthermore, the prying action uses the lever principle, which makes it easier to press the insert into the fixed axis, thus easily and conveniently completing the disassembly of the insert and further improving the convenience and practicality of the mold.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] 1. In this utility model, by setting a limiting plate and using a fixing component, multiple grinding wheels can be fixedly connected to a fixed shaft from left to right. In this way, different numbers of grinding wheels can be fixed on the fixed shaft according to the width of the groove to be ground, so that the grinding wheels can smoothly extend into the depth of the groove, thereby enabling the grinding wheels to fully grind the groove and improving the grinding effect and quality of the grinding tool.

[0014] 2. In this utility model, the disassembly component allows the groove to be fitted onto the round rod. Then, the pry bar is pried away from the fixed shaft using the round rod as an axis. This allows the pressure rod to pass through the insertion hole and press the insertion rod into the fixed shaft, thereby releasing the limiting fixation of the insertion cylinder. Furthermore, the pry bar's movement uses a lever principle, which makes it easier to press the insertion rod into the fixed shaft, thus easily and conveniently completing the disassembly of the insertion cylinder and further improving the convenience and practicality of the mold.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please refer to Figures 1-6 The grinding wheel of a grinding machine shown includes a fixed shaft 1. The left end of the fixed shaft 1 is fixedly connected to the output end of a drive motor. The drive motor drives the fixed shaft 1 to rotate, thereby driving the grinding wheel 3 to rotate and grind the workpiece. A limit plate 2 is fixedly sleeved on the outer circumferential surface of the fixed shaft 1. Multiple grinding wheels 3 are sleeved on the outer circumferential surface of the fixed shaft 1 along the axis of the fixed shaft 1. A fixing component 4 is provided on the fixed shaft 1. Multiple grinding wheels 3 are pressed together in sequence. The left side of the leftmost grinding wheel 3 is pressed together with the right side of the limit plate 2.

[0026] The fixing component 4 is used in conjunction with the limiting plate 2 to fix multiple grinding wheels 3 onto the fixed shaft 1.

[0027] refer to Figure 2 and Figure 3 The fixing component 4 includes two sets of straight holes 41 symmetrically opened on the outer circumferential surface of the fixing shaft 1. Two sets of push rods 42 are symmetrically slidably connected in the two sets of straight holes 41 through a third elastic element. The fixing component 4 also includes two limiting holes 43 symmetrically opened on the inner side wall of the grinding wheel 3. The push rods 42 can be inserted into the limiting holes 43. The top surface of the push rods 42 is an inclined surface. The inner top wall of the limiting hole 43 is an inclined surface parallel to the top surface of the push rods 42. The top surface of the push rods 42 is inclined away from the limiting plate 2. The fixing component 4 also includes a transmission mechanism 44 provided on the fixing shaft 1. The transmission mechanism 44 is used to push the two sets of push rods 42 to slide towards each other. The fixing component 4 also includes a limiting mechanism 45 used to limit the transmission mechanism 44 to prevent the transmission mechanism 44 from continuing to drive the push rods 42 to slide. The fixing component 4 also includes a disassembly mechanism 46 used to release the limiting mechanism 45 from limiting the transmission mechanism 44.

[0028] Specifically, the transmission mechanism 44 pushes the two sets of push rods 42 to move in opposite directions until they are pressed tightly against the inner top wall of the upper limit hole 43 on the inner side wall of the multiple grinding wheels 3. Then, the limiting mechanism 45 limits the transmission mechanism 44, thus completing the fixing of the multiple grinding wheels 3. The top surface of the push rod 42 is tilted away from the limiting plate 2, so the push rod 42 can cooperate with the limiting plate 2 to improve the fixing firmness of the grinding wheels 3, ensuring that the grinding wheels 3 can perform high-speed rotation grinding normally, thus improving the reliability of the grinding tool.

[0029] refer to Figure 2 and Figure 3 The transmission mechanism 44 includes a transverse hole 441 opened at the center of the right end face of the fixed shaft 1 along the axis of the fixed shaft 1. The ends of the two sets of straight holes 41 that are close to each other are connected to the transverse hole 441. Multiple isosceles trapezoidal driving blocks 442 are slidably connected in the transverse hole 441 along the axis of the fixed shaft 1. The multiple driving blocks 442 are fixedly connected together in sequence. The sides of the two sets of push rods 42 that are close to each other are symmetrical inclined surfaces. The sides of the two sets of push rods 42 that are close to each other are parallel to and fit against the inclined surfaces of the multiple driving blocks 442. A first elastic element 443 is fixedly connected between the left side of the leftmost driving block 442 and the left inner wall of the transverse hole 441. A push rod 444 is fixedly connected to the right side of the rightmost driving block 442. When the push rod 444 moves to the right, it can extend to the outside of the transverse hole 441.

[0030] Specifically, simply pushing the push rod 444 to the left will conveniently and quickly drive multiple drive blocks 442 to move synchronously to the left and push the two sets of push rods 42 to insert into the two sets of limiting holes 43 respectively, which improves the efficiency of the fixing operation and thus improves the practicality of the mold.

[0031] refer to Figures 3-6 The limiting mechanism 45 includes two insert rods 451 that are symmetrically and movably inserted into the outer circumferential surface of the fixed shaft 1 via a second elastic element. The two insert rods 451 have symmetrical inclined surfaces on their opposite sides. The limiting mechanism 45 also includes an insert cylinder 452 that is movably inserted into the right end of the fixed shaft 1. Two insertion holes 453 are symmetrically opened on the inner side wall of the insert cylinder 452. The two insert rods 451 can be movably inserted into the two insertion holes 453 respectively. The opposite ends of the two insertion holes 453 both penetrate the outer side wall of the insert cylinder 452.

[0032] Specifically, simply align the two insertion holes 453 with the two insertion rods 451 respectively, then fit the insertion cylinder 452 onto the right end of the fixed shaft 1, and with the inclined surface at the top of the insertion rod 451, the two insertion rods 451 can limit the inner wall of the insertion cylinder 452 to be compressed into the fixed shaft 1. Then, when the insertion rod 451 is aligned with the insertion hole 453, it can spring back under the elastic force of the second elastic element and be inserted into the insertion hole 453. This can easily complete the fixing of the insertion cylinder 452, so that the insertion cylinder 452 can push the push rod 444 to a position close to the left side, so that the push rod 42 can be stably inserted into the limiting hole 43, thereby ensuring that the push rod 42 can stably fix the grinding wheel 3 on the fixed shaft 1, improving the reliability of the grinding tool.

[0033] refer to Figures 3-6The disassembly mechanism 46 includes two pairs of vertical plates 461 symmetrically fixedly connected to the outer circumference of the insert 452. Two round rods are symmetrically fixedly connected between the adjacent sides of the two pairs of vertical plates 461. The disassembly mechanism 46 also includes two pry bars 462. The bottom end of the pry bar 462 is provided with an arc-shaped groove 463. The groove 463 can be sleeved on the round rod. Two pressure rods 464 are symmetrically fixedly connected to the right side of the two pry bars 462. The two pressure rods 464 can extend into the interior of the insert 453.

[0034] Specifically, the groove 463 is fitted onto the round rod, and then the pry bar 462 is pried away from the fixed shaft 1 with the round rod as the axis. This allows the pressure bar 464 to pass through the insertion hole 453 and press the insertion rod 451 into the fixed shaft 1, thus releasing the limiting fixation of the insertion cylinder 452. At this time, under the elastic force of the first elastic element 443, the drive block 442 and the push rod 444 slide to the right. Thus, the drive block 442 no longer exerts a pushing force on the push rod 42, so that the two sets of push rods 42 slide towards each other under the elastic force of the third elastic element until they are pulled out from the limiting hole 43. This conveniently releases the fixation of the grinding wheel 3. Furthermore, the pry bar 462 prying adopts the lever principle, which makes it easier to press the insertion rod 451 into the fixed shaft 1, thereby easily and conveniently completing the disassembly of the insertion cylinder 452, further improving the convenience and practicality of the grinding tool.

[0035] The limiting mechanism 45 also includes two symmetrically opened inclined grooves 454 on the right side of the grinding wheel 3. The grinding wheel 3 is made of iron, and a grinding layer is fixedly connected to the outer circumference of the grinding wheel 3. The limiting mechanism 45 also includes two strong magnet blocks 455 symmetrically hinged to the outer circumference of the insert 452. The two strong magnet blocks 455 can be rotated into the two inclined grooves 454 respectively and attracted to the inner sidewall of the inclined groove 454. Two hooks 456 are symmetrically fixedly connected to the right side of the two strong magnet blocks 455. The disassembly mechanism 46 also includes two hook plates 465 symmetrically fixedly connected to the left side of the two pry bars 462. The two hook plates 465 can hook the two hooks 456 respectively to drive the strong magnet blocks 455 to separate from the inner sidewall of the inclined groove 454. This can further enhance the connection firmness of the insert 452 on the fixed shaft 1 and further improve the reliability of the grinding tool.

[0036] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
