Abstract

A cushioning sponge grinder for a mini four-wheel drive vehicle, particularly a cushioning sponge grinder having a motor mount and a base along the X-axis of a main body. The motor mount has a motor and a grinding head. The base has an adjustment seat and a sliding plate. The adjustment seat has an angle adjustment device. The sliding plate can hold a cushioning sponge to be processed. The processing angle of the cushioning sponge is adjusted by the angle adjustment device. A slide rail and a front and rear propulsion device are provided along the Y-axis of the main body. The motor mount slides through the slide rail. The front and rear propulsion device drives the grinding head to grind the cushioning sponge at an angle.

Claims

1. A cushioning sponge abrasive for a mini four-wheel drive vehicle, the cushioning sponge abrasive mainly comprising: A base, a slide rail seat, a motor seat, a front and rear propulsion device, a base, and an angle adjustment device; wherein: the slide rail seat is pivotally mounted on one side of the base, and a lower groove is provided on the other side of the base for locking the front and rear propulsion device; the base is locked to the front of the base; one side of the slide rail seat is pivotally integrated with the base, and a slide rail is provided on the other side for the motor seat to pass through; a protrusion is provided on the slide rail seat corresponding to the slide rail for locking a handwheel; the handwheel has a clamp for clamping the motor seat; a groove is provided on the motor seat corresponding to the slide rail for passing through the slide rail; the motor seat has a housing for accommodating a motor; the motor has a grinding head; and an upper groove is provided on the motor seat corresponding to the lower groove for locking the front and rear propulsion device. The forward and backward propulsion device has two frames, upper and lower, which are locked together by the upper and lower grooves. Two swing elements are pivotally mounted inside the two frames. The two swing elements have two through holes for a rocker arm to pass through. A first elastic element is provided between the two through holes. The bottom end of the rocker arm is locked to the swing element. The motor seat is moved by the rocker arm swinging forward and backward. An adjustment seat is pivotally mounted on one side of the base. The adjustment seat has a linear slide and a linear slide rail. The linear slide rail has a sliding plate for placing a cushioning sponge to be processed. The base and the adjustment seat have two frames and two cantilever arms for pivotally mounting the angle adjustment device. The angle adjustment device has an upper seat and a lower seat, which are pivotally mounted on the two cantilever arms and the two frames. The upper seat and the lower seat have through holes for an adjustment handwheel to pass through. A second elastic element is provided between the two through holes. The bottom end of the adjustment handwheel is locked to the lower seat. The angle of the adjustment seat can be adjusted up and down by tightening or loosening the adjustment handwheel.

2. The cushioning sponge abrasive of the mini 4WD vehicle as described in claim 1, wherein: The base has four pads at the bottom for stable placement.

3. The cushioning sponge abrasive as described in claim 1 for a mini 4WD vehicle, wherein: The motor mount has a front cover plate and a rear cover plate locked at the front and rear of the housing, thereby covering and fixing the motor to the housing.

4. The cushioning sponge abrasive of the mini 4WD vehicle as described in claim 1, wherein: The motor is covered with a piece of sandpaper on the outside of the grinding head.

5. The cushioning sponge abrasive of the mini 4WD vehicle as described in claim 1, wherein: The motor is connected to a power cord.

6. The cushioning sponge abrasive of the mini 4WD vehicle as described in claim 1, wherein: The base has a dial on one side of the frame, and the adjustment seat has an indicator corresponding to the dial, which can be used to indicate the adjustment angle of the dial.

7. The cushioning sponge abrasive of the mini 4WD vehicle as described in claim 1, wherein: Two pivot ears are provided on one side of the base, and two pivot ears are provided with two shaft holding elements. The slide rail seat is provided with a pivot part corresponding to the two pivot ears, so that the two pivot elements can pivot the slide rail seat to the base.

8. The cushioning sponge abrasive of the mini 4WD vehicle as described in claim 1, wherein: The base is provided with two pivot lugs, which allow two pivoting elements to pivot the adjusting seat to the base.

9. The cushioning sponge abrasive of the mini 4WD vehicle as described in claim 1, wherein: The cushioning sponge is made of pearl cotton.
