Embodiment Construction

[0009] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0010] With reference to the accompanying drawings, the present invention provides a kind of intermittent linear power mechanism that is driven by rollers to move the cam. The first frame 1 is fixed with a drive shaft 13, and a turntable 3 is installed on the drive shaft 13, and the turntable 3 is evenly distributed along the circumference. A roller 2, a driven shaft 6 is fixed on the second frame 14 above the turntable 3, a cam 5 is installed on the driven shaft 6, the free end of the cam 5 is connected with the upper end of the turntable screw 7, and the turntable screw 7 The lower end is connected with the front section of rocking bar 8, and the front end of rocking bar 8 is installed on the supporting shaft 12, and the rear end is lapped on the top of the slide block 10, which is connected with the lower end of spring 9. The slide block 10 ...

Abstract

The invention relates to the field of intermittent power mechanisms, and discloses an intermittent linear power mechanism with a cam pushed by rollers to move. The intermittent linear power mechanismcomprises a driving shaft, a rotary disc, the rollers and the cam. The rotary disc is mounted on the driving shaft. The rollers are evenly distributed on the rotary disc in the circumferential direction. A driven shaft is arranged above the rotary disc. The cam is mounted on the driven shaft. In the movement process of the rotary disc, the roller intermittently makes contact with the cam; the freeend of the cam is connected with the upper end of a turnbuckle, and the lower end of the turnbuckle is connected with the front section of a rocker; the front end of the rocker is mounted on a supporting shaft, and the rear end of the rocker is in lap joint with a sliding block; and the sliding block is connected with the lower end of a spring, and the upper end of the spring is fixed to a thirdrack. By adoption of the intermittent linear power mechanism with the cam pushed by the rollers to move, the problem that in the prior art, a cam type intermittent mechanism cannot directly provide linear power for an actuator under a long-distance condition is solved.

Description

technical field [0001] The invention specifically relates to the field of intermittent power mechanisms, and more particularly relates to an intermittent linear power mechanism in which a roller drives a cam to move. Background technique [0002] The traditional cam-type intermittent mechanism is a mechanism that pushes several rollers distributed on the turntable through the circular motion of the cam, so that the turntable rotates intermittently. This kind of intermittent mechanism is difficult for intermittent linear motion actuators (such as precision The spotter in hole sowing, etc.) provides power directly. When the distance between the actuator and the power source is far, using the traditional cam-type intermittent mechanism as the power requires a series of additional transmission mechanisms, which will inevitably cause unnecessary energy loss. The production and assembly accuracy requirements of the traditional cam-type intermittent mechanism are generally low. It...
