Description

Technical Field

[0001] This utility model relates to the field of USB processing equipment technology, and in particular to a USB polishing machine. Background Technology

[0002] During the manufacturing process, the ends of USB have burrs that require secondary processing. During secondary processing, the required angle is ground according to the product requirements. In the past, the USB was clamped with a fixture and its relative position was adjusted before grinding could be performed, which was inefficient and therefore needs to be improved. Utility Model Content

[0003] The purpose of this invention is to provide a USB polisher to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A USB polishing machine includes a polishing mechanism and a mounting fixture. The polishing mechanism includes a base, a motor, a grinding wheel mounting base, and a polishing wheel. The motor is mounted on the base. The grinding wheel mounting base is mounted on one side of the motor via a connecting flange. The polishing wheel is mounted inside the grinding wheel mounting base and connected to the power output end of the motor. The mounting fixture includes a connecting frame, an XY-axis fine-tuning platform, a slant seat, and a mounting base. One end of the connecting frame is fixed to one side of the grinding wheel mounting base. The XY-axis fine-tuning platform is fixed on the connecting frame and located in front of the polishing wheel. The slant seat is fixed above the XY-axis fine-tuning platform. The upper surface of the slant seat is an inclined surface that slopes from the rear upper part to the front lower part. The mounting base is fixed above the slant seat. The rear end face of the mounting base is an arc surface. The rear part of the mounting base has a vertical insertion hole. The lower rear corner of the insertion hole extends to the rear end face of the mounting base, forming a workpiece protrusion.

[0006] In a further description of this utility model, two grinding wheel mounting seats are provided and are respectively installed on the left and right sides of the motor via connecting flanges; two grinding wheels are provided and are respectively installed in the two grinding wheel mounting seats; both ends of the motor are provided with power output ends for connecting the grinding wheels; two sets of mounting fixtures are provided and are respectively installed on the two grinding wheel mounting seats.

[0007] In a further description of this utility model, the connecting frame includes a vertically arranged side plate and a top plate horizontally connected to the upper end of the side plate; the side plate is provided with a first waist-shaped hole arranged along the front-back direction; the side plate is locked to one side of the grinding wheel mounting seat by a first screw passing through the first waist-shaped hole.

[0008] Further description of this utility model: the inclined seat is provided with two second waist-shaped holes distributed from left to right; the second waist-shaped holes are arranged along the front-back direction; the inclined seat is locked to the XY axis fine-tuning platform by a second screw passing through the second waist-shaped holes.

[0009] The beneficial effects of this utility model are as follows:

[0010] This design involves inserting the USB with the plug end facing down into the socket. After insertion, the lower rear corner of the USB protrudes from the workpiece outlet. The XY-axis fine-tuning platform is used to adjust the front-back and left-right positions of the USB before starting the motor to control the grinding wheel to grind the lower rear corner of the USB. After the grinding wheel wears down, its position can be readjusted using the XY-axis fine-tuning platform. The inclined seat provides a certain angle for the USB, allowing for the grinding of the required chamfer. Depending on the product, different inclined seats with varying angles can be used. This design is easy to operate and has high processing efficiency. Attached Figure Description
