[0034] A handle 7 is fixed on the side of the polishing barrel 4, and a groove for receiving the handle 7 is formed at the bottom of the barrel cover 5. A positioning hole for the fixing column 602 to pass through is provided inside the handle 7. The fixing column 602 passes through the positioning hole to realize the positioning and fixing of the polishing barrel 4;

[0035] The locking unit includes a connecting block 604, a locking block 605, a locking plate slot 606, a locking plate 607, and a first spring 608;

[0036] Two connecting blocks 604 are fixed to the bottom end of the fixing column 602 and are slidably connected to the inside of the fixing column 602. The locking block 605 is fixed between the two connecting blocks 604.

[0037] The locking plate groove 606 is provided at one end of the inner wall of the fixed column groove 601, the locking plate 607 is slidably connected inside the locking plate groove 606, and one end thereof penetrates the inner side of the fixed column groove 601, the locking plate 607 is attached to the top of the locking block 605, and is used to realize locking of the locking block 605;

[0038] The first spring 608 is connected between the other end of the locking plate 607 and the other end of the locking plate slot 606;

[0039] The unlocking unit includes a sliding square column 603, a handle 609, a pressing plate 610 and a second spring 611;

[0040] The handle 609 is fixed to the top of the barrel cover 5, and the sliding square column 603 passes through the handle 609, the barrel cover 5, the fixed column 602 and between the two connecting blocks 604 in sequence from the top of the handle 609. One end of the bottom of the sliding square column 603 is in contact with the end surface of the locking plate 607, and the contact surface is an inclined structure;

[0041] The pressing plate 610 is fixed to the top of the fixing column 602, and the second spring 611 is connected between the top of the handle 609 and the bottom of the pressing plate 610;

[0042] An electromagnet 8 is fixed to the top of the output end of the fixed barrel 2 , and the top of the electromagnet 8 is close to the bottom of the polishing barrel 4 .

[0043] In this embodiment, when it is necessary to grind the surface of the cone hub, after adding a magnetic needle, water and abrasive into the polishing barrel 4, the cone hub to be grinded is placed into the polishing barrel 4, the polishing barrel 4 is placed into the fixed barrel 2, the handle 609 above the barrel cover 5 is grasped, the fixed column 602 is aligned with the top opening of the fixed column groove 601, and the barrel cover 5 is moved downward, so that the locking block 605 squeezes the inclined surface of the locking plate 607, and the locking plate groove 606 limits the locking plate 607, so that the locking plate 607 slides and the first spring 608 is compressed by pressure. When the bottom end of the connecting block 604 contacts the top of the fixed column groove 601, the first spring 608 rebounds and resets, driving the locking plate 607 to reset, so that the locking plate 607 locks the locking block 605, and then the motor 3 and the electromagnet 8 are started, and the motor 3 causes the energized electromagnet 8 to rotate, so that the movement of the magnetic needle drives the water and the abrasive to rotate and move, and the abrasive grinds the surface of the cone hub;

[0044] Then, the motor 3 and the electromagnet 8 are turned off to stop the magnetic needle from moving, and the pressing plate 610 is pressed to make the second spring 611 contract under pressure, driving the sliding square column 603 to move downward, so that the sliding square column 603 squeezes the inclined surface of the locking plate 607, so that the locking plate 607 slides and the first spring 608 is contracted under pressure. Because the height of the inclined surface where one end of the locking plate 607 fits with the bottom end of the fixed column 602 is less than the height of the non-inclined surface at one end of the locking plate 607, at this time, one end of the locking plate 607 fits with one end of the sliding square column 603, and the width of the locking block 605 is the same as the width of the fixed column 602. The locking block 605 is made to slide out from one end of the locking plate 607 by holding the handle 609 above the barrel cover 5 and moving the barrel cover 5 upward, so that the fixed column 602, the sliding square column 603, the connecting block 604 and the locking block 605 are separated from the fixed column groove 601, and at the same time, the first spring 608 rebounds and resets, driving the locking plate 607 to reset, and then releases the pressing plate 610 to make the second spring 611 rebound and reset, driving the sliding square column 603 to reset, so as to facilitate the next locking of the barrel cover 5, hold the handle 7, take out the polishing barrel 4, separate the cone hub from the abrasive, and complete the grinding of the cone hub surface.

[0045] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the fixed column groove 601, the fixed column 602, the sliding square column 603, the connecting block 604, the locking block 605, the locking plate groove 606, the locking plate 607 and the first spring 608 are symmetrically arranged in two groups to facilitate the fixation of the polishing barrel 4 and the barrel cover 5.

[0046] In this embodiment, the polishing barrel 4 and the barrel cover 5 will not shake due to vibration when the grinding device is working, and the cone hub will not suffer other damages during the shaking.

[0047] In a further preferred embodiment of the present invention, Figure 1-3As shown, a transverse protrusion is formed at the bottom of the sliding square column 603, and the end surface of the transverse protrusion is flush with the end surface of the outer wall of the fixed column 602, and the locking plate 607 is in contact with the bottom of the transverse protrusion.

[0048] In this embodiment, the locking plate 607 can release the locking of the locking block 605, thereby ensuring that the fixing column 602 can be taken out.
