The upper surface of the slot plate 53 is sequentially provided with a plurality of front-to-back facing slots from left to right. When the card slot plate 53 moves upward, the T-shaped card plate 35 will be inserted into the card slot. At this time, if the sliding seat 50 drives the card slot plate 53 to move left and right, the T-shaped card plate 35 will interfere with the card slot, so that the T-shaped card plate 35 moves left and right with the card slot plate 53, so that the upper driven shaft 24 moves left and right synchronously. A rack 54 arranged in a left-right direction is provided on the lower surface of the lower lifting plate 52.

When the lifting cross bar 58 contacts the high-position limiting groove 59, the lifting plate 52 is at a high position. At this time, the card The slot plate 53 is in contact with the T-shaped card plate 35. When the lifting cross bar 58 is in contact with the low-position limiting groove 59, the lifting plate 52 is in a low position. At this time, the rack 54 is in contact with the driven gear 18. Under the action of gravity, the lifting cross bar 58 can be guaranteed to always be in contact with the triangular top block 60.

The rear end of the clamping screw 27 is rotatably connected to the front side of the transverse slide bar 23, so that the clamping rod 29 is pushed forward and backward by the clamping screw 27, so that the front brake block 32 and the side brake block 31 can move forward and backward to cooperate with the driven pulley 25 and the guide slide bar 13 respectively.

[0032] In one case of the present embodiment, the clamping head assembly 37 includes a telescopic rod 41 slidably connected to one end of the driven rotating shaft 24 near the center of the base 1, the telescopic rod 41 is arranged in a front-to-back direction, a rotating ball head 42 is arranged at the end of the telescopic rod 41, and a clamping disc 43 is rotatably connected to the end of the rotating ball head 42. The surface of the clamping disc 43 is coated with a wear-resistant rubber material to improve the friction force, and the clamping disc 43 can be pitched and adjusted by the rotating ball head 42, so that when the inclined surface is clamped, the clamping disc 43 can also be aligned with the workpiece to be processed. The aluminum part 63 is fitted, and a clamping plate 39 is arranged on the side of the driven rotating shaft 24. The clamping plate 39 is arranged with three evenly distributed relative to the axis of the driven rotating shaft 24. A clamping screw 38 arranged in a front-to-rear direction is threadedly connected to the end of the clamping plate 39. A clamping ball head 40 cooperating with the clamping disk 43 is arranged at the end of the clamping screw 38. The angle and the front-to-rear position of the clamping disk 43 are adjusted by adjusting the different positions of the three clamping screws 38, so that the fixing processing of the aluminum part 63 to be processed is completed by the front and rear clamping disks 43.

[0033] In one case of the present embodiment, the grinding assembly 4 includes a suspension frame 5 fixedly connected to the base 1, the suspension frame 5 is L-shaped, the vertical plate of the suspension frame 5 is fixed at the middle of the rear side of the base 1, the horizontal plate of the suspension frame 5 is arranged in the front-to-back direction in the middle directly above the base 1, and a vertically arranged grinding slide bar 6 is slidably connected to the front and back sides of the horizontal plate of the suspension frame 5, the lower end of the grinding slide bar 6 is fixedly connected to the suspension plate 9 arranged in the front-to-back direction, a grinding motor 10 is arranged in the middle of the suspension plate 9, the output shaft of the grinding motor 10 is fixedly connected to the grinding head 11, and a push plate 8 arranged in the front-to-back direction is fixedly connected above the grinding slide bar 6, an electric telescopic rod 7 is arranged on the suspension frame 5, and the protruding end of the electric telescopic rod 7 is connected to the push plate 8, so as to adjust the height of the push plate 8, that is, to achieve the adjustment of the height of the grinding head 11.

At this time, the rack 54 is in contact with the driven gear 18. At this time, when the sliding seat 50 moves left and right, the clamping head assembly 37 can drive the aluminum part 63 to be processed to rotate around the center of the driven rotating shaft 24. The upper grinding head 11 can now perform arc surface grinding on the rotating arc surface of the aluminum part 63 to be processed.

[0037] When the grinder is in use, if the aluminum part 63 to be processed is large in size and it is necessary to change the plane for plane grinding, first, the rack 54 and the driven gear 18 in the arc surface grinding are used to rotate the aluminum part 63 to be processed by a certain angle and then the plane grinding is performed. Or, if the length of the aluminum part 63 to be processed is long, the aluminum part 63 to be processed is only rotated at the center position of the base 1. The height of the grinding head 11 is not enough to complete the arc surface grinding. The slot plate 53 and the T-shaped clamping plate 35 in the plane grinding are used to move the aluminum part 63 to be processed to one side of the base 1. At this time, the arc surface grinding is performed again, thereby making the entire grinder more convenient to use.
