Description

Eccentric shaft with adjustable amplitude

Technical Field

The utility model relates to an eccentric shaft technical field especially relates to an eccentric shaft of adjustable amplitude.

Background

The eccentric shaft is fixed on the rotating shaft of the motor through an eccentric hole, and when the motor is started, the eccentric shaft makes a cam motion. The eccentric shaft can transmit not only rotation but also revolution, and therefore, the eccentric shaft is often used as a mechanism for generating reciprocating movement. However, since the eccentric output end of the eccentric shaft is an output with a fixed amplitude, the flexibility of the eccentric shaft is poor, and if the amplitude of the output needs to be adjusted, the eccentric shaft needs to be replaced integrally, which is time-consuming and labor-consuming.

As a further description of the above technical solution:

the sliding groove is of a concave structure.

As a further description of the above technical solution:

the bottom of the moving block is provided with a convex strip, the convex strip is matched with the sliding groove, and two sides of the moving block are provided with first racks.

As a further description of the above technical solution:

the clamping device is characterized in that a clamping block is arranged at the bottom of the clamping block, a second threaded hole is formed in the clamping block, a second rack is arranged on the side face of the clamping block, and the first rack is meshed with the second rack.

As a further description of the above technical solution:

the clamping groove is matched with the clamping block, and the first threaded hole and the second threaded hole are in threaded connection with bolts.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

the utility model discloses in, be provided with the axle bed, the grip block, the movable block, first rack, the second rack, the spout, the draw-in groove, first screw hole, the spindle nose, the bolt, the fixture block, the second screw hole, axis body and sand grip structure, the movable block slides along the spout on the base and can adjusts the distance between spindle nose and the axis body, grip block and movable block carry on spacingly through first rack and second rack intermeshing to the movable block, when the eccentric shaft of the amplitude that needs the difference, only need unload the bolt and adjust the eccentric shaft that the position of movable block in the spout can obtain an amplitude difference, need not change a brand-new eccentric shaft festival and save manpower and material resources.
