Specific Embodiment

[0017] Refer to Figures 1-5 , this embodiment is an automatic grinding device for dove-tail ribs, including a conveyor belt 5. A support flat plate 4 is arranged inside the conveyor belt 5, and the support flat plate 4 is used to assist in supporting the workpiece 2 passing through the belt. A grinding mechanism 3 is arranged on one side of the conveyor belt 5. The grinding mechanism 3 includes a fixed seat 38. A drive box 36 is installed on one side of the fixed seat 38 facing the conveyor belt 5. A grinding wheel 31 is installed at the output end of the drive box 36. The input end of the drive box 36 is connected with a drive motor. A pressure guide wheel 32 is installed on each side of the outer wall surface of the drive box 36 on both sides of the grinding wheel 31, and a spring is installed above the pressure guide wheel 32.

[0018] Further, a track 39 arranged in the vertical direction is provided on one side of the fixed seat 38. The drive box 36 is slidably connected with the track 39. A support plate is provided on one side of the fixed seat 38, and a screw 34 is rotatably connected to the support plate. The screw 34 penetrates through the drive box 36 and is threadedly connected with the drive box 36. Further, a hand wheel is installed at one end of the screw 34.

[0019] Further, vertical slide rails 35 are installed on the outer surface of the driving box 36 corresponding to each pressure guide wheel 32. Sliders 33 are installed on the slide rails 35, and the sliders 33 are rotatably connected to the central axes of the corresponding pressure guide wheels 32. A fixing plate 37 is installed above the slide rails 35 on the driving box 36, and a compression spring is installed between the fixing plate 37 and the sliders 33.

[0020] Further, through holes are provided in the fixing plate 37, and screw rods are installed on the tops of the sliders 33 corresponding to the through holes. The screw rods pass upward through the through holes and are provided with adjusting nuts.

[0021] Further, this embodiment further includes a box body 1. The conveyor belt 5 and the grinding mechanism 3 are installed in the box body 1. A dust extraction pipe 6 is provided on one side of the box body 1. Openings are provided at the front end and the rear end of the box body 1 corresponding to the dovetail ribs. The outer end of the dust extraction pipe 6 is connected to a dust collection device.

[0022] When the utility model works, a set of idler rollers is placed on each side of the entrance and the exit of the box body 1, and then the height of the grinding wheel 31 is adjusted to a suitable position according to the height of the dovetail rib. The specific adjustment method is to drive the screw rod 34 to rotate through the handwheel, so that the driving box 36 moves vertically up and down along the track 39. After moving to the specified position, the height is locked. Then the workpiece 2 is fed into the box body 1 from the entrance on one side, and the workpiece 2 is sent out to the exit on the other side through the transmission belt. The lowest point of the pressure guide wheels 32 is lower than the lowest point of the grinding wheel 31. Therefore, when the workpiece 2 passes through the two pressure guide wheels 32, the two pressure guide wheels 32 press the workpiece 2 tightly against the conveyor belt 5 under the action of the compression spring. At the same time, the height of the pressure guide wheels 32 is automatically raised by the workpiece 2, increasing the friction between the workpiece 2 and the conveyor belt 5, so that the conveyor belt 5 moves the workpiece 2 forward at a slow speed. The driving box 36 drives the grinding wheel 31 to rotate at a high speed to automatically grind the top surface of the workpiece 2. The dust generated during the grinding process is automatically discharged through the dust extraction pipe 6 and flows into the dust collection device; when the workpiece 2 leaves the conveyor belt 5, the top surface of the workpiece 2 is automatically ground.
