Of course, they are only examples and the purpose is not to limit the present application.

[0030] The embodiments of the present application will be described in detail below with reference to the drawings.

[0031] Embodiment One

[0032] Please refer to Figures 1-4 As shown in the figure, the embodiment discloses a grinding wheel dressing equipment, which comprises a support table 1, the top of the support table 1 is provided with a fixing assembly for fixing a grinding wheel 4, the fixing assembly comprises a support plate 2, a first motor 3, an air expansion shaft and an air pump 11, the support plate 2 is arranged on the top of the support table 1, the first motor 3 is arranged on the top of the support plate 2, the output end of the first motor 3 is provided with the air expansion shaft, that is, the first motor 3 can drive the air expansion shaft to rotate. The air pump 11 is arranged on the top of the support table 1, and the air pump 11 is communicated with the air expansion shaft, that is, the air expansion shaft is inflated by the air pump 11, so that the air expansion shaft is expanded and the grinding wheel 4 is fixed, then the connection between the air pump 11 and the air expansion shaft is disconnected, then the first motor 3 is started to drive the grinding wheel 4 to rotate, it is worth noting that after the air pump 11 inflates the air expansion shaft and makes the air expansion shaft expand to fix the grinding wheel 4, the connection with the air expansion shaft needs to be disconnected, so as to avoid the influence of the connecting piece between the air pump 11 and the air expansion shaft when the first motor 3 rotates.

[0033] A support frame 5 is installed at the top of the aforementioned support bar. A grinding component 6 is installed near the bottom of the support frame 5. The grinding component 6 has a grinding gap, allowing the grinding wheel 4 to enter and grind it. Specifically, the grinding component 6 includes: a first fixing block 60, two connecting rods 61, a diamond pen 65, a first telescopic rod 62, a first adjusting block 63, a second adjusting block 64, and two return springs. The first fixing block 60 is installed on the bottom outer wall of the support frame 5. An internal cavity 601 is formed, and two first through holes 602 are respectively formed on the opposite side walls of the first fixed block 60. The two first through holes 602 are connected to the first cavity 601. A connecting rod 61 is set inside the two first through holes 602. A diamond pen 65 is set at the end of each connecting rod 61 outside the first fixed block 60, so that the connecting rod 61 can slide between the first fixed block 60 and the first fixed block 60 through the first through holes 602, and the diamond pen 65 can fit against the surface of the grinding wheel 4 to complete the grinding of the grinding wheel 4. A second adjusting block 64 is set at the end of the two connecting rods 61 facing the inside of the first cavity 601. A first telescopic rod 62 is set inside the first cavity 601. A first adjusting block 63 is set on the working end of the first telescopic rod 62. The first adjusting block 63 is generally conical in shape, and the first telescopic rod 62 is adjusted by telescoping towards the grinding wheel 4. Two return springs are installed inside the first cavity 601. One end of each return spring is fixedly connected to the end face of the second adjusting block 64 facing the first through hole 602, and the other end is connected to the inner wall surface of the first fixing block 60 located in the first cavity 601. That is, when the first telescopic rod 62 is stretched in the direction toward the grinding wheel 4, the first adjusting block 63 on the telescopic end of the first telescopic rod 62 will squeeze the second adjusting blocks 64 on the ends of the two connecting rods 61. After the two second adjusting blocks 64 are squeezed, the two connecting rods 61 will move toward the first fixing block 602. When the external movement of the 0 causes the two connecting rods 61 to move the diamond pen 65, the grinding gap between the diamond pens 65 can be adjusted to increase, thereby adapting to the grinding of the thickness of the grinding wheel 4 at different positions along its own central axis. When the first telescopic rod 62 retracts in the opposite direction to the grinding wheel 4, the return spring provided between the two connecting rods 61 and the inner wall of the first fixed block 60 can drive the connecting rods 61 to move towards the inside of the first cavity 601, which can adjust the grinding gap between the diamond pens 65 to decrease.

[0034] Two distance rods are arranged on the top outer wall surface of the support frame 5, and an adjusting assembly 7 is arranged between the two distance rods and the polishing assembly 6. The adjusting assembly 7 can adjust the polishing gap between the two diamond pens 65 in the polishing assembly 6 according to the gap between the two distance rods. Specifically, the adjusting assembly 7 comprises a second fixed block 70, two sliding rods 72, an induction coil 71, two spring sheets 73, a magnetic flux meter 75, a controller 76 and a power supply 74. The second fixed block 70 is arranged on the top outer wall surface of the support frame 5. A second cavity 701 is formed in the second fixed block 70, and a second through hole 702 is formed in the opposite side wall surface of the second fixed block 70. The two second through holes 702 are in communication with the second cavity 701. The sliding rod 72 is arranged in each second through hole 702, so that the sliding rod 72 is slidably connected with the second fixed block 70 through the second through hole 702. The induction coil 71 is arranged in the second cavity 701. The induction coil 71 has a gap in the middle position, which corresponds to the second through hole 702. When the sliding rod 72 moves in the second through hole 702, it can enter the induction coil 71 through the gap. It should be noted that the outer diameter of the sliding rod 72 is equal to the inner diameter of the induction coil 71, so that when the sliding rod 72 enters the induction coil 71 through the gap, the cross-sectional area of the induction coil 71 changes. Two spring sheets 73 are arranged on the outer wall surface of the second fixed block 70. The two spring sheets 73 correspond to the two sliding rods 72. The spring sheet 73 is clamped between the other end of each spring sheet 73 and the corresponding sliding rod 72. Specifically, a clamping groove is formed in the outer wall surface of each sliding rod 72. The spring sheet 73 is clamped with the sliding rod 72 through the clamping groove, so that the position of the sliding rod 72 can be reset.The power supply 74 is arranged inside the second cavity 701 and connected with the induction coil 71, which is used to supply power to the induction coil 71. When the current passes through the induction coil 71, the induction coil 71 generates a magnetic field. According to the formula Φ = BS, when the slide rod 72 moves in the induction coil 71, the cross-sectional area of the induction coil 71 changes, which causes the magnetic flux to change. The changing magnetic flux can be recorded by the fluxmeter 75 arranged at the top of the second cavity 701. The measuring end of the fluxmeter 75 penetrates through the second fixed block and enters the inside of the second cavity 701. The fluxmeter 75 records the change of the magnetic flux in the induction coil 71. The recorded data can be transmitted to the controller 76 arranged at the top of the second fixed block 70 and electrically connected with the fluxmeter 75. After receiving the data signal and processing accordingly, the controller 76 sends the data signal to the first telescopic rod 62. The first telescopic rod 62 performs stretching or retraction movement according to the specific situation. The telescopic end of the first telescopic rod 62 is pressed by the first adjusting block 63 and the second adjusting block 64 on the two connecting rods 61, so as to adjust the polishing gap between the two diamond pens 65. The polishing gap between the two diamond pens 65 can be adjusted according to the thickness of the grinding wheel 4 at different positions on the center axis.

[0035] The second motor 8 is arranged on the top of the support table 1. A lead screw 80 is arranged on the output end of the second motor 8, which divides the support frame 5 into an upper support frame 50 and a lower support frame 51. The upper support frame 50 is used to fix the adjusting assembly 7, and the lower support frame 51 is used to fix the polishing assembly 6. A first connecting block 52 is arranged on the end face of the upper support frame 50 facing the lower support frame 51, and a second connecting block 53 is arranged on the end face of the lower support frame 51 facing the upper support frame 50. A first adjusting groove 520 is formed in the bottom of the first connecting block 52, and a first nut 521 is arranged in the first adjusting groove 520. A second adjusting groove 530 is formed in the top of the second connecting block 53, and a second nut 531 is arranged in the second adjusting groove 530. The first nut 521 and the second nut 531 are both rotationally connected with the lead screw 80 on the output end of the second motor 8, and the rotation directions of the first nut 521 and the second nut 531 are opposite to each other. When the second motor 8 operates, the upper support frame 50 and the lower support frame 51 either move towards each other or move away from each other, so as to simultaneously adjust the positions of the distance rods and the diamond pens 65 and the contact points of the grinding wheel 4.

For details, please refer to Figure 1As shown, the chute 10 is opened on the top of the support table 1, so that the support frame 5 can be connected with the support table 1 through the sliding connection between the chute 10 and the support table 1, when the grinding wheel 4 needs to be installed on the fixed assembly, the support frame 5 is moved, so that the installation of the grinding wheel 4 is not blocked, then the support frame 5 is moved again, so that the grinding wheel 4 enters the polishing gap between the two distance rods in the support frame 5, at the same time, the diamond pen 65 at the other end of the support frame 5 can be adjusted according to the polishing gap between the two distance rods. In addition, the fixing piece 54 is arranged on the outer wall surface of the support frame 5, and the top of the support table 1 is provided with a plurality of fixing holes, the fixing bolt 540 is threadedly connected on the fixing piece 54, and the fixing bolt 540 can be threadedly connected with the support table 1 through the fixing hole, so as to limit the support frame 5, and avoid the influence of the movement of the support frame 5 on the polishing of the diamond pen 65 on the grinding wheel 4.
