Abstract

The invention discloses a variable-speed shake mechanism. The variable-speed shake mechanism comprises a base, an oscillating bar, a gear connected to the base and a rack slidingly connected to the base, wherein the rack is driven by a cylinder, the gear is engaged with the rack, a cam is coaxially connected to the gear, the cam is detachably connected with the gear and propped against the oscillating bar, the oscillating bar is a telescopic structure, and one end of the oscillating bar is hinged to a frame, while the other end of the oscillating bar is connected to the frame through a spring. The variable-speed shake mechanism is characterized in that the cylinder drives the rack to move and then the rack drives the gear to rotate, as the cam is coaxially connected with the gear, the gear is capable of driving the cam to rotate, and the cam drives the oscillating bar to swing. In use, the amplitude and the swinging speed of the oscillating bar can be regulated by selecting the number of teeth of the gear and the shape of the cam. Simultaneously, the cam is detachably connected with the gear, so that different gears and cams can be selected conveniently. The oscillating bar is the telescopic structure so that the length of the oscillating bar can be regulated according to practical situations.

Description

technical field

[0001] The invention belongs to the technical field of transmission devices. Background technique

[0002] At present, a four-bar mechanism is most commonly used as a reciprocating mechanism, but when the four-bar mechanism is transmitting, the swing range is determined by the size of the four-bar mechanism. However, in some production and processing, we need a mechanism with adjustable swing amplitude and swing speed, and the existing four-bar mechanism cannot meet the requirements of adjustable swing amplitude and swing speed. Contents of the invention

[0003] The invention provides a variable-speed rocking mechanism to solve the problem that the existing mechanism cannot realize the adjustable swing amplitude and swing speed.

[0004] In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions: A variable-speed rocking mechanism, including a base, a swing rod, a gear connected to the base, ...
