The two bevel gears 3 are meshed and connected. A dual-axis motor 4 is fixedly connected to the front surface of the concave member 1.

[0032] When the device is in use, by starting the dual-axis motor 4, under the meshing transmission of the two bevel gears 3, the two mutually perpendicular grinding rollers 38 can be driven to rotate together, thereby achieving the effect of right-angle grinding;

[0033] The left side of concave member 1 and the right side of concave member 2 are both fixedly connected to a slider 6, the inner side of the slider 6 is slidably connected to a guide column 7, the bottom ends of the two guide columns 7 are commonly fixedly connected to a base plate 8, the upper surface of the base plate 8 is fixedly connected to the lower surface of the air pressure box 1 9, and the outer wall of the guide column 7 is provided with a spring 15, the two ends of the spring 15 are respectively fixedly connected to the opposite sides of the slider 6 and the base plate 8;

[0034] The concave part 1 and the concave part 2 can slide up and down along the outer side walls of the two guide pillars 7 through the slider 6, thereby facilitating the up and down movement and grinding effect;

[0035] A vertical plate 21 is fixedly connected to the right side of the upper surface of the bottom plate 8. A vertical slot 22 is formed on the right side of the vertical plate 21.

A fixed clamp 26 is fixedly connected to the right side of the vertical plate 21 below the lifting clamp 25. The top end of the screw 23 passes through the top of the vertical plate 21 and is fixedly connected to the knob 37.

[0036] By rotating the screw rod 23 with the hand-held knob 37, the screw block 24 can be controlled to rise or fall along the vertical slot 22, thereby facilitating the control of the lifting clamp 25 to move closer to or away from the fixed clamp 26, thereby facilitating the clamping of parts to be polished of different thicknesses.

[0037] like Figure 4 and Figure 5 As shown, the rear end of the output shaft of the dual-axis motor 4 is fixedly connected to the front end of the central axis of the grinding roller 38 located inside the concave part 1, and the front end of the output shaft of the dual-axis motor 4 is fixedly connected to the conical cone 5; an air pressure box 9 is provided below the conical cone 5, and a piston plate 10 is slidably connected to the interior of the air pressure box 9.

The outer wall of the abutment wheel 14 contacts the outer wall of the conical cone 5, and a spring 2 16 is fixedly connected between the air pressure box 9 and the piston plate 10.

[0038] When the dual-axis motor 4 is started, it drives the conical table 5 to rotate together. The conical table 5 is eccentrically mounted on the front end of the shaft of the dual-axis motor 4, and the upper surface of the air pressure box 9 at the bottom of the conical table 5 is parallel to that of the contact wheel 14. When it rotates and contacts the contact wheel 14, it drives the grinding roller 38 to move up and down repeatedly. Moreover, by inflating or deflating air into the air pressure box 9, the contact wheel 14 can be controlled to move forward or backward, contacting different positions of the conical table 5. When the conical table 5 rotates, it can drive the grinding roller 38 to rise to different heights, thereby facilitating right-angle grinding for parts of different thicknesses.

[0039] An air pressure box 2 17 is provided on the upper surface of the bottom plate 8 and is located on the right side of the air pressure box 1 9. A piston plate 2 18 is slidably connected to the interior of the air pressure box 2 17. An air exchange pipe 19 is fixedly connected between the air pressure box 2 17 and the air pressure box 1 9.

[0041] like Figure 1 、 Figure 5 and Figure 6 As shown, a plurality of through-type air suction holes 28 are opened on the upper surface of the fixed splint 26, and an air box 1 29 is fixedly connected to the lower surface of the fixed splint 26. An air box 2 30 is slidably connected to the interior of the air box 1 29, and a guide rod 39 is fixedly connected to the lower surface of the air box 2 30. A sliding member 31 is slidably connected to the outer wall of the guide rod 39, and a toggle rod 40 is slidably connected to the interior of the sliding member 31. The front end of the toggle rod 40 is fixedly connected to the rear surface of the tilt push rod 27;

[0042] The lifting splint 25 descends, driving the tilting push rod 27 to move. Under the connection of the sliding part 31 and the guide rod 39, the air box 2 30 can be pulled to slide along the air box 1 29, so that air can be sucked through the suction hole 28, and then the plate-shaped parts placed on the upper surface of the fixed splint 26 can be tightly adsorbed, further ensuring the stable placement of the plate-shaped parts during grinding.

The bottom ends of the two connecting pieces 1 32 are both rotatably connected to a collection box 33 via a rotating shaft. The outer wall of the collection box 33 is rotatably connected to a connecting piece 2 34 via a rotating shaft. The bottom ends of the two connecting pieces 2 34 are jointly fixedly connected to a collection box 35. A hose 36 is fixedly connected between the collection boxes 33.

[0044] When the concave part 1 and the concave part 2 move up and down repeatedly, the connection between the connecting piece 1 32 and the connecting piece 2 34 will drive the collection box 33 to tilt up and down. Then, during grinding, the debris can be collected by the collection box 33, and the debris collected inside the collection box 33 can be introduced into the collection box 35 through the hose 36 for centralized collection and processing.

[0045] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention.
