Description

Technical Field

[0001] The utility model relates to the technical field of grinders, in particular to a small grinder for gear processing. Background Art

[0002] A grinder is an electric tool used for grinding metal surfaces. It can quickly repair deep scratches and minor scrapes, and quickly grind and polish. The grinder has a strong sense of vibration when operated, and it is easy to fall off if held in hand for a long time. It has low stability, and the grinding process will also generate dust, affecting the health of the surrounding environment.

[0003] After searching, the application with patent number CN213289748U discloses a small polishing machine for plate roller gear processing, including a base plate, a pillar, a workbench, a gantry bracket and a grinder, the top of the base plate is connected to the bottom end of the pillar, and the top of the pillar is connected to the bottom end of the workbench; it also includes a grinding base, the grinding base includes a first rail, a second rail, a lifting plate, a fixed bearing, a first gear, a motor base, a motor and multiple sets of telescopic columns, the left end of the first rail is connected to the inner wall of the pillar, so that it is convenient to grind the top surface of the gear.

[0004] However, due to the setting of the turntable and the motor, the gear is placed horizontally on the turntable, so the top surface grinder can only grind the top surface of the gear, but not the bottom and side surfaces of the gear. This makes it inconvenient to use and has low grinding efficiency. At the same time, due to the setting of the fixture, the fixture clamps the side surface of the gear, and the side surface of the gear is arc-shaped, resulting in a small contact area between the fixture and the gear, and the clamping is not firm, which is prone to shaking, affecting the grinding effect of the grinder.

[0005] Therefore, we proposed a small grinding machine for gear processing. Utility Model Content
