As shown in fig. 1 to 7, the technical scheme adopted in this embodiment is as follows: a grinding wheel end face water tank forming grinding tool convenient to fix, comprising: the grinding wheel mounting device comprises a base 1, wherein a fixing base 2 is fixedly arranged on the upper portion of the base 1, a lantern ring 3 is concentrically and fixedly arranged on the upper portion of the fixing base 2, the outer diameter of the lantern ring 3 is matched with the diameter of a grinding wheel mounting hole, and the grinding wheel is conveniently mounted on the fixing base 2 through the lantern ring 3. The inner thread of the lantern ring 3 is connected with a bolt 4, and the upper end of the bolt 4 is fixedly provided with a bolt head 41, so that the bolt 4 can be conveniently screwed through the bolt head 41. The lower part of bolt 4 is fixed and is provided with spline shaft 42, the one end that bolt 4 is close to spline shaft 42 is equipped with the chamfer, the ring wall internal activity of lantern ring 3 is provided with locking Assembly, locking Assembly cooperates with the chamfer of bolt 4, through rotatory bolt 4, makes bolt 4 drive spline shaft 42 rotatory to when making bolt 4 remove to lantern ring 3, promote locking Assembly through the chamfer to fix the emery wheel of cover on lantern ring 3 outer peripheral face, avoid the follow-up circumstances such as unexpected not hard up dislocation to the emery wheel in the basin abrasive machining process.

The spline shaft 42 is sleeved with a push plate 6 matched with the spline shaft 42, and the push plate 6 is provided with a key groove matched with a spline of the spline shaft 42. The push plate 6 is rotatably connected to the bottom of the collar 3. A plurality of top plates 61 are slidably arranged in the fixed seat 2, and one ends of the top plates 61, which are close to the central shaft of the fixed seat 2, are matched with the push plate 6. The fixed seat 2 internal fixation is provided with the second spring 62, the one end and the inner wall fixed connection of fixed seat 2 of second spring 62, the other end and the roof 61 fixed connection of second spring 62, evenly distributed has a plurality of archs on the push pedal 6 outer peripheral face, every the arch all correspond the setting with roof 61. When the bolt 4 drives the spline shaft 42 to move downwards in the rotating process, the spline shaft 42 drives the push plate 6 to rotate, so that the push plate 6 rotates, the corresponding top plate 61 is gradually pushed to move to the outer side of the fixed seat 2 by the bulge on the push plate 6, the top plate 61 supports the outer edge of the grinding wheel from the lower part of the grinding wheel, and the grinding wheel is prevented from being broken due to overlarge pressure of the grinding tool 78 in the processing process.

The locking assembly comprises a press block 5, a connection plate 51 and a first spring 52. The pressing blocks 5 are arranged in a plurality, the pressing blocks 5 are arranged in the lantern ring 3 in a sliding mode, and one end, close to the axis of the lantern ring 3, of each pressing block 5 extends into the lantern ring 3. The upper part of one end of the pressing block 5 extending into the lantern ring 3 is provided with an arc surface, and the arc surface is matched with the chamfer angle of the lower part of the bolt 4. The lower part of one end of the pressing block 5 far away from the axis of the lantern ring 3 is a cambered surface.

Working principle: when the novel grinding wheel is used, the mounting hole of the grinding wheel is first sleeved on the outer peripheral surface of the lantern ring 3, and then the bolt head 41 is screwed by using a spanner, so that the bolt head 41 drives the bolt 4 to rotate and move into the lantern ring 3. In the process of moving the bolt 4 into the lantern ring 3, the chamfer on the bolt 4 is gradually contacted with the cambered surface on the pressing block 5, and the pressing block 5 is pushed to move outwards of the lantern ring 3 through the cambered surface, so that the pressing block 5 compresses the first spring 52 through the connecting block. Meanwhile, when the pressing block 5 moves outwards of the lantern ring 3, the cambered surface of one end of the pressing block 5 away from the connecting block is gradually contacted with the upper surface of the grinding wheel, the grinding wheel is gradually pressed, dislocation of the grinding wheel in the machining process is avoided, and the grinding quality of the water tank is improved.

At the same time, the bolt 4 drives the spline shaft 42 to rotate, so that the spline shaft 42 drives the push plate 6 to rotate in the downward movement process of the push plate 6, and the corresponding top plate 61 is gradually pushed to move to the outer side of the fixed seat 2 by the bulge outside the push plate 6, and the second spring 62 is stretched in the outward movement process of the top plate 61. Simultaneously, the top plate 61 moves outwards, so that the top plate 61 supports the grinding wheel from the outer edge of the grinding wheel, and the grinding wheel is prevented from being broken due to overlarge pressure of the grinding tool 78 in the processing process.

The grinder 78, the first motor 72, and the second motor 75 are then activated. The first motor 72 drives the first screw 71 to rotate, so that the first screw 71 drives the sliding plate 73 to move, and the second motor 75 drives the sliding block 76 to move through the screw, so that the sliding block 76 drives the electric telescopic rod 77 to move. At the same time, the electric telescopic rod 77 is extended as required to drive the grinding tool 78 to grind the end face of the grinding wheel.

After the water tank is finished, the grinding tool 78 is closed, and the first motor 72 and the second motor 75 drive the grinding tool 78 to move to the safe position. Then, the worker uses the wrench to reversely screw the bolt head 41, so that the bolt head 41 drives the bolt 4 to reversely rotate, thereby the bolt 4 drives the spline shaft 42 to move towards the upper part of the lantern ring 3, further the chamfer on the bolt 4 is gradually separated from the pressing block 5, the pressing block 5 moves towards the inside of the lantern ring 3 under the action of the first spring 52, and the extrusion fixation of the grinding wheel is cancelled. Meanwhile, the spline shaft 42 drives the push plate 6 to rotate, so that the bulge on the push plate 6 is gradually separated from the top plate 61, the top plate 61 moves towards the inside of the fixed seat 2 under the action of the tension of the second spring 62, the next processing is performed, and the cleaning of scraps on the bottom plate by workers is facilitated.
