Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a deburring mechanism for shaft parts. Background Art

[0002] At present, after shaft parts are cut, burr structures protruding outward are easily generated on the edge of the shaft end face. Whether it is to prevent the burr structure from scratching the human body or to make the cut shaft meet the size requirements, the burrs need to be removed in time after the shaft parts are cut.

[0003] Patent No. CN117428611A proposes a deburring device for shaft parts. For the removal of burrs on the end faces of shaft parts, a grinding machine is mostly used to rotate around the edge of the end face of the shaft part to grind and remove the burrs. This deburring method is relatively traditional and is only applicable to round shaft parts. When encountering square shaft parts, the grinding machine cannot fully contact the edge of the end face of the square shaft part during rotation, resulting in poor burr removal effect.

[0004] When the above-mentioned shaft component deburring device is deburring the end face of the other shaft component, the grinding sleeve will have a great friction force that will hinder the movement of the grinding sleeve, and the weight of the grinding sleeve itself will also have a certain resistance to limit the movement of the grinding sleeve. At the same time, the weight of the grinding sleeve itself will make the grinding sleeve with the ball head as the center point so that the grinding sleeve mouth is always in a downward state. If the grinding sleeve mouth is to be level, a large force must be applied to the ball head through the lever principle, and the grinding sleeve can move in an arc with a cross trajectory through the repulsion of the magnetic sheets. It is necessary to overcome the friction force and the grinding sleeve's own gravity, which requires a large magnetic force and has great limitations. Utility Model Content

The column barrel 7 passes through the sliding frame 2 and rotates with the sliding frame 2. The motor gear 72 is located inside the grinding assembly 8 and connected to the rotating shaft 44. The outer wall of the output shaft 41 is fixedly provided with a first guide strip 43 along the length direction. The outer wall of the column barrel 7 is fixedly provided with a second guide strip 71 along the length direction. The sliding sleeve 5 is movably sleeved on the outside of the column barrel 7. The column barrel 7 is T-shaped. The axis of the column barrel 7 is located at the same position as the axis of the grinding assembly 8. The connecting seat 6 is fixedly mounted with a sub-gear 61, and the sub-gear 61 is matched with the motor gear 72. The grinding roller 9 is fixed to the connecting seat 6 by fixing screws 10, and the connection is detachable. The sliding frame 2 is in a lying L-shape.

[0030] Working principle: When deburring the end face of a circular shaft-like component, one end of the circular shaft-like component can be inserted between the two grinding rollers 9 so that the two grinding rollers 9 are in contact with the edge of the circular shaft-like component. By adjusting the sliding sleeve 5, the cylinder 7 and the output shaft 41 are rotated synchronously under the action of the first guide strip 43, the second guide strip 71 and the slots on the inner wall of the sliding sleeve 5 that can cooperate with the first guide strip 43 and the second guide strip 71. The burrs are polished and removed by the friction between the grinding roller 9 and the edge of the end of the circular shaft-like component; when deburring the end face of a square shaft-like component, one end of the square shaft-like component can be inserted between the two grinding rollers 9 so that the two grinding rollers 9 are spaced from the square shaft-like component. The two surfaces are in contact, and the sleeve 5 is adjusted to separate the column tube 7 from the output shaft 41. The motor 42 drives the rotating shaft 44 through the output shaft 41, thereby driving the motor gear 72 to rotate. The rotation of the motor gear 72 drives the sub-gear 61 and the connecting seat 6 to rotate, thereby driving the grinding roller 9 to rotate. In this process, there is no contact between the output shaft 41 and the column tube 7, so the grinding assembly 8 is stationary as a whole, and the grinding roller 9 rotates. At this time, the electric push rod 3 and the sliding frame 2 are used to make the grinding roller 9 slide to grind the burrs on the opposite surfaces of the square shaft parts, and grind the other two sides to turn the square shaft parts over so that the other two sides are in contact with the two grinding rollers 9. When the grinding roller 9 needs to be replaced, unscrew the fixing screw 10 to replace the grinding roller 9.
