Stroke-adjustable type intermittent movable mechanical device based on non-circular gear divider

Abstract

A stroke-adjustable type intermittent movable mechanical device based on a non-circular gear divider comprises a power supplying and braking device, an indexing device and a stroke-adjustable crank block device. A variable-frequency and variable-speed motor of the power supplying and braking device is connected with the input end of a brake through an elastic sleeve pin coupler. The output end of the brake transfers force to the indexing device. The indexing device is the non-circular gear divider, the input end of the indexing device is connected with the output end of the brake, and the output end of the indexing device is connected with the stroke-adjustable crank block device. The stroke-adjustable crank block device is composed of a crank disc, an adjusting bolt, a connecting rod, a working actuating device and a hinging device, wherein the crank disc is connected with the output end of the non-circular gear divider and the connecting rod, and the connecting rod is connected with the working actuating device through the hinging device. According to the device, intermittent reciprocating movement of a working mechanism is achieved, the moving stroke is large, the stroke range is adjustable, the motion precision is high, impact and noise are quite low, the transmission efficiency is high, the service life is long, and the stroke-adjustable type intermittent movable mechanical device can be used for high-speed heavy loads.

Description

technical field [0001] The invention belongs to the field of mechanical transmission, and in particular relates to an adjustable stroke intermittent movement mechanical device based on a non-circular gear divider. Background technique [0002] In engineering practice, intermittent motion mechanisms are widely used. For example, the realization of the horizontal feed movement of the planer table, the realization of the film feeding movement of the movie projector, the completion of the feeding, packaging, testing and other processes in the automated production line, the realization of the automatic tool change process of the automatic tool change manipulator in the machine tool processing Wait. [0003] At present, the mechanisms used to realize intermittent motion in engineering mainly include cam mechanism, ratchet mechanism, groove wheel mechanism, incomplete gear mechanism, etc. Most of the intermittent motion mechanisms only involve rotary intermittent motion, and there...
