[0021] A working method of a motorcycle frame grinding device, the working method comprising the following steps:

[0022] Step 1: After the motorcycle frame is positioned and loaded into one of the bottom plates, the first barrier plate enters between the two adjacent bottom plates to block and isolate, and then the motorcycle frame is loaded into the other vacant bottom plate, and the bearing bracket slides on the slide rail to discharge the completed workpiece from the other side, and the second barrier plate moves down to enter between the two bottom plates to block, and the motorcycle frame on the other bottom plate continues to be ground;

[0023] Step 2: During positioning, the two side plates push the corresponding wrapping part to contact the motorcycle frame and position it elastically. The grinding assembly enters the entry cavity, and the grinding position is changed by the sliding of the linear guide rail. During grinding, the angle of the grinding sheet is changed in the vertical direction by the rotation of the guide seat and the flip seat, and the distance between the grinding sheet and the grinding position is changed by the rotation of the flip seat and the grinding motor. The guide seat slides at the bottom of the mounting plate to grind the frames of different widths.

After the bottom plates in the other group are ground, the electric push rod pushes the driving gear to slide downward in the driving shaft and then meshes with the driven gear, thereby blocking the chip-falling holes in the other group of chip removal chambers.

[0025] Step 4: Drive the slide plate and the mounting rod to slide in a limited position through the lead screw. Under the push of the chip pusher plate and the sliding groove, the chip pusher plate drives the mounting rod and the slide plate to elastically extend. The chip pusher plate slides on the top surface of the base, and the mounting rod and the slide plate slide into the interior of the push plate. The waste chips on the upper surface of the bottom plate enter the corresponding gathering parts along the two guide parts, and then fall into the interior of the chip removal groove. The metal chips in the waste chips are magnetically adsorbed by the rolling magnetic roller and collected by classification.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. Install a bottom plate on the bearing bracket into the motorcycle frame, move the two side plates closer, fix the motorcycle frame by covering it with elastic sponge, and slide it into the grinding chamber. At this time, the bottom plate on the other side is exposed, and the motorcycle frame is installed from the other side. The motorcycle frame can be installed from both sides of the grinding chamber, saving the time of stopping the machine to install the workpiece. The scattered waste chips are gathered together by the chip pusher, and the rolling magnetic roller rotates to magnetically absorb the metal waste chips. The scattered waste chips are guided to the position of the gathering part by the guide part, and the gathering part is connected with the chip discharge groove. At this time, the chip pusher in the chip pusher groove pushes the waste chips into multiple chip discharge grooves, and the magnetic roller rotates to absorb the magnetic waste chips in the waste chips. The rotating magnetic roller puts the metal waste chips into the metal waste chip groove, and the two different waste chips are classified and collected;

[0028] 2. After the motorcycle frame is positioned and loaded into one of the bottom plates and enters the grinding chamber, the first barrier plate enters between the two adjacent bottom plates to block and isolate, and the motorcycle frame is loaded on the other vacant bottom plate. The bearing bracket slides on the slide rail to discharge the finished workpiece from the other side, and the second barrier plate moves down to enter between the two bottom plates to block, and the motorcycle frame on the other bottom plate continues to be ground to protect it;

[0029] 3. During chip removal, the through hole in the hole blocking plate is aligned with the hole position of the chip falling hole, so that the waste chips fall and enter the chip collecting groove cavity. The driving gear drives the gear ring and drives the hole blocking plate to rotate. At this time, the through hole is not connected with the chip falling hole, and the hole blocking plate blocks the chip falling holes in one group of chip removal cavities; after the bottom plate in the other group is ground, the electric push rod pushes the driving gear to slide downward in the driving shaft and then meshes with the driven gear, so that the other gear ring and its hole blocking plate rotate to block the chip falling holes in the other group of chip removal cavities. When not in use, the chip removal cavity is blocked, which adapts to the discharge and blocking of grinding waste materials of the two bottom plates and meets the use of different states;

[0030] 4. During grinding, the angle of the grinding sheet is changed in the vertical direction by the rotation of the guide seat and the flip seat, the distance between the grinding sheet and the grinding position is changed by the rotation of the flip seat and the grinding motor, and the skeletons of different widths are ground by the sliding of the guide seat at the bottom of the mounting plate to improve the grinding quality of the motorcycle skeleton.
