[0024] Clamping assembly 4 includes two electric telescopic rods fixedly connected to the top of moving table 3, and the output end of the electric telescopic rod is fixedly connected with a clamping plate, the car piston is placed between the two clamping plates on the top of the moving table 3, and the electric telescopic rod works to drive the clamping plate to contact the side wall of the car piston, thereby clamping and fixing the car piston.

[0025] In the initial state, the protection cover 10 is located above the car piston, the hydraulic cylinder 5 works to drive the top plate 6 to move downward, the top plate 6 drives the fixed plate 8, the side plate 9 and the protection cover 10 to move downward synchronously through the spring 7, until the protection cover 10 is attached to the moving table 3, at this time the car piston is located in the protection cover 10, and the processing part 11 mills the car piston, and the waste is retained in the protection cover 10.

[0026] As shown in Figures 3-4 As a preferred embodiment, on the basis of the above-mentioned mode, further, the processing part 11 includes a fixed column 111 fixedly connected to the bottom of the top plate 6, the fixed plate 8 and the protection cover 10 are both in sliding connection with the fixed column 111, the bottom end of the fixed column 111 is provided with a processing head 112, the processing head 112 is located in the protection cover 10, the top plate 6 moves to drive the fixed column 111 and the processing head 112 to move synchronously, when the protection cover 10 is attached to the moving table 3, the hydraulic cylinder 5 continues to work, the top plate 6 continues to move downward, the spring 7 is compressed, the fixed column 111 and the processing head 112 move downward relative to the protection cover 10, the processing head 112 contacts the car piston to mill the car piston, the fixed column 111 is square, and since the protection cover 10 is in sliding connection with the fixed column 111, the protection cover 10 will not rotate.

[0027] As shown in Figures 3-4As shown, in a preferred embodiment, based on the above method, the cleaning unit 12 further includes two motors 121 fixedly connected to the bottom of the fixing plate 8. The output end of the motors 121 is connected to a lead screw 122. The top of the protective cover 10 has two clearance openings 123. The lead screw 122 passes through the corresponding clearance openings 123. The lower half of the outer peripheral surface of the lead screw 122 is threadedly connected to a screw plate 124. An electromagnetic chuck 125 is fixedly connected to the side of the screw plate 124 near the processing head 112. Four vertical rods 126 are fixedly connected to the bottom of the fixing plate 8. The screw plate 124 and the corresponding two vertical rods 126 are slidably connected.

[0028] The side of the screw plate 124 away from the electromagnetic chuck 125 is attached to the inner wall of the protective cover 10. In the initial state, the electromagnetic chuck 125 is located in the lower half of the protective cover 10. During the milling of the automobile piston, the electromagnetic chuck 125 generates magnetism and attracts the waste chips generated during milling. After the automobile piston is finished, the motor 121 drives the lead screw 122 to rotate, thereby driving the screw plate 124 to move upward. The screw plate 124 and the electromagnetic chuck 125 pass through the clearance opening 123 and move to the top of the protective cover 10.

[0029] like Figure 4 As shown, in a preferred embodiment, based on the above method, a baffle 14 is fixedly connected to the top of the screw plate 124. The baffle 14 is located inside the corresponding clearance opening 123, and the outer wall of the baffle 14 is in contact with the inner wall of the corresponding clearance opening 123. The lead screw 122 is threadedly connected to the baffle 14, and the vertical rod 126 is slidably connected to the corresponding baffle 14. In the initial state, the baffle 14 covers the clearance opening 123 to prevent waste from being discharged from the clearance opening 123, thereby further improving the waste collection effect of this device.

[0030] like Figure 3 As shown, in a preferred embodiment, based on the above method, the collecting part 13 further includes two electric push rods 131 fixedly inserted through one side of the side plate 9. When the screw plate 124 moves upward, it passes between the corresponding two electric push rods 131. The output ends of the corresponding two electric push rods 131 are jointly and fixedly connected to a collecting shell 132 with a top opening. The bottom surface of the collecting shell 132 is in contact with the top surface of the protective cover 10. A drawer 133 with a top opening is slidably inserted through the front side of the collecting shell 132.

[0031] When the screw plate 124 and the electromagnetic chuck 125 move upward, they will not contact the collecting shell 132. When the electromagnetic chuck 125 moves above the collecting shell 132, the electric push rod 131 works to drive the collecting shell 132 to move, and the collecting shell 132 moves partially below the electromagnetic chuck 125, and the length of the collecting shell 132 is greater than the length of the electromagnetic chuck 125. At this time, the electromagnetic chuck 125 stops, and the scrap falls into the drawer 133 in the collecting shell 132 under the action of gravity, so that the collection of the scrap is completed. When the scrap in the drawer 133 accumulates too much, the worker can pull out the drawer 133 to clean the scrap.

[0032] Specifically, when the milling machine for milling the bosses and grooves on the automobile piston works, first, the automobile piston is placed on the moving table 3 and fixed through the clamping assembly 4, then the hydraulic cylinder 5 works to drive the top plate 6 to move downward, the protective cover 10 contacts the moving table 3, then the hydraulic cylinder 5 continues to work to drive the machining head 112 to move vertically in the protective cover 10, and the automobile piston is milled by cooperating the machining head 112. At this time, the electromagnetic chuck 125 works, so that the scrap in the protective cover 10 is attracted on the electromagnetic chuck 125.

[0033] After the automobile piston is processed, the motor 121 works to drive the screw plate 124 and the electromagnetic chuck 125 to move upward until the electromagnetic chuck 125 moves above the collecting shell 132, then the electric push rod 131 works to drive the collecting shell 132 to move partially below the electromagnetic chuck 125, the electromagnetic chuck 125 stops, the scrap falls into the collecting shell 132, then the electric push rod 131 works reversely, the collecting shell 132 returns to the original position, the motor 121 reverses, the screw plate 124 and the electromagnetic chuck 125 return to the original position, and the cleaning of the scrap is completed.

[0034] When the scrap in the drawer 133 accumulates too much after multiple cleanings, the worker can pull out the drawer 133 to clean the scrap.

[0035] The above is only a preferred specific implementation manner of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
