[0024] It is worth mentioning that the driving member 4 includes a cylinder, and the cylinder is fixedly installed on the top of the support frame 2. The axial end of the cylinder is fixedly connected to the mounting frame 3. The mounting frame 3 is driven to rise and fall by the cylinder. The advantage is that the lifting method is convenient for using racks of different heights on the one hand, and on the other hand, it is convenient to clean the iron filings on the top of the processing table 1.

[0025] Furthermore, the mounting frame 3 is of a U-shaped structure, and a motor 31 is fixedly mounted on its side, a rotating shaft 32 is rotatably connected inside the mounting frame 3, one end of the rotating shaft 32 is fixedly connected to the shaft end of the motor 31, and a plurality of slots 33 are opened on the periphery of the end portion, a pair of the chamfering wheels 6 are arranged opposite to each other, and they are fixedly connected to the rotating shaft 32 via the clamping member 5.

[0026] Specifically, the motor 31 drives the rotating shaft 32 to drive the pair of chamfering wheels 6 to rotate, thereby achieving the purpose of grinding the two ends of the rack.

[0027] Furthermore, the clamping member 5 includes a mounting portion 51 arranged on the side of the chamfering wheel 6, and a cross-shaped groove 52 is opened in the mounting portion 51. The inside of the cross-shaped groove 52 is horizontally slidably connected to an unlocking rod 53 and longitudinally slidably connected to a locking rod 54. The bottom of the locking rod 54 is provided with a protrusion 55, and the protrusion 55 can be clamped into the clamping groove 33.

[0028] In more detail, a first spring 56 is fixedly connected between the inner side surface of the cross-shaped groove 52 and the side surface of the unlocking rod 53, a groove is penetrated through the side surface of the locking rod 54, and a slider 57 is provided in the groove, and an inclined groove 58 is penetrated through one end of the unlocking rod 53, and the unlocking rod 53 and the inclined groove 58 are slidably connected to the groove and the slider 57 respectively.

[0029] Specifically, the unlocking rod 53 fixes the slider 57 by means of the inclined groove 58 under the support of the first spring 56, and the locking rod 54 moves downwards under the constraint of the inclined groove 58 because the slider 57 is fixed, and the protrusion 55 is used to engage the locking groove 33 to fix the chamfering wheel 6;

[0030] The side of the inclined slot 58 away from the first spring 56 is inclined upward, and the spacing between the pair of chamfering wheels 6 is adjusted to facilitate adapting to racks of different widths;

[0031] It should be noted that if Figure 4As shown, it is not difficult for those skilled in the art to understand that the drawings are provided for reference. Under normal circumstances, a cover plate is also provided on the side of the cross-shaped groove 52, and the cover plate is used to close the cross-shaped groove 52 to prevent the unlocking rod 53 and the locking rod 54 from detaching from the cross-shaped groove 52.

[0032] In general, the feeding part 7 includes a feeding box 71, the top of the processing table 1 is slidably connected to a feeding plate 12 through a slide rail 11, and a cylinder 13 and the feeding box 71 are fixedly installed on both sides of the top, the axial end of the cylinder 13 is fixedly connected to the feeding plate 12, and a pair of electric clamps 15 for clamping racks are fixedly installed on the top of the feeding plate 12 through a recessed portion 14, a plurality of racks are placed inside the feeding box 71 through a receiving groove 72, and a discharge groove 73 communicating with the receiving groove 72 is penetrated at the bottom of the feeding box 71, and the feeding plate 12 is slidably connected to the discharge groove 73.

[0033] Finally, a sealing plate 74 for placing a rack is hinged on the side of the feed box 71, and a T-bar 75 is slidably connected to the top of the feed box 71 in the accommodating groove 72.

The two ends of the second spring 76 are fixedly connected to the sides of the feed box 71 and the T-bar 75 respectively.

[0034] The specific operation is that the rack is placed in the receiving groove 72 through the sealing plate 74, and the sealing plate 74 and the feed box 71 are fixed by buckles;

[0035] In particular, considering that the rack is not polished and friction may occur between the racks or between the racks and the receiving groove 72, the T-shaped rod 75 is required to press the rack. The T-shaped rod 75 presses the rack tightly under the support of the second spring 76 to prevent the rack from being stuck and unable to unload materials.

[0036] It should be noted that a shielding portion 121 extends from the top of the feed plate 12 toward one side of the cylinder 13, and the shielding portion 121 can close the feed chute 73. After the rack falls into the recessed portion 14, it is fixed by a pair of electric clamps 15. When the feed plate 12 pushes the rack for chamfering, the shielding portion 121 contacts the rack in the accommodating groove 72 and closes the feed chute 73 to prevent the rack from unloading and jamming the feed plate 12.

[0037] Working mode: When working, after the mounting frame 3 is adjusted to a suitable height by the driving member 4, the unlocking lever 53 is pressed to make it drive the slider 57 to slide by the inclined groove 58, so as to drive the locking lever 54 to move upward, and the locking lever 54 drives the protrusion 55 to disengage from the locking groove 33 to adjust the position of the chamfering wheel 6. After the unlocking lever 53 is released, the unlocking lever 53 drives the locking lever 54 to slide under the action of the first spring 56, so that the protrusion 55 is inserted into the locking groove 33 to fix the chamfering wheel 6.

[0038] Then, multiple racks are placed into the accommodating groove 72 from the sealing plate 74, and the T-bar 75 is pressed against the racks under the action of the second spring 76. The cylinder 13 drives the feeding plate 12 so that the feeding plate 12 uses the recessed portion 14 and a pair of electric clamps 15 to feed and fix the racks, and then a pair of chamfering wheels 6 are used to chamfer and grind the racks.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
