[0002] The reciprocating mechanism is widely used in compressors, winders, wire take-ups and other devices. It has various forms, and the most typical one is a crank-link mechanism composed of a crank, a connecting rod, and a slider. The connecting rod One end is hinged on the crank, and the other end is installed on the slider. The power system drives the crank to rotate, and then converts the swing of the connecting rod into the reciprocating motion of the slider; the existing design similar to the above structure has many disadvantages: The connection between the rod and the crank is a sliding friction, which not only has a large friction resistance, consumes a lot of energy, but also has serious wear and tear, which affects the accuracy and service life of the mechanism; if the connecting rod is in a swing mode, the speed of the swing mode is difficult to control, especially in reciprocating motion. The frequency and speed cannot be guaranteed

Embodiment Construction
[0016] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.
[0017] Such as figure 1 As shown, a ball-type reciprocating mechanism, which includes a rotating body 1, a guide rail 2, a fixed frame 3, a slider 4 and a ball 5, the rotating body 1 is cylindrical, and its peripheral surface is provided with a circle around the rotating body 1, And the grooved rail 11 connected end to end, the grooved rail 11 and the axial direction of the rotating body 1 are arranged obliquely, that is, the circumference of the grooved rail 11 is greater than the circumference of the radial section of the rotating body 1; the guide rail 2 is parallel to the axial direction of the rotating body 1 The two ends are respectively equipped with fixing brackets 3 for fixing the guide rail 2. The guide rail 2 can be designed as one or more than one guide rail according to the requirements, and the guide rails 2 are arranged in p...

The invention discloses a ball type reciprocating mechanism which comprises a rotating main body, a guide track, fixing supports, a sliding block and a ball. The rotating main body is a cylinder, grooved tracks connected in an end-to-end mode are arranged on the circumferential face of the rotating main body, and the grooved tracks and the rotating main body are inclined axially. The guide track and the rotating main body are parallel axially. The fixing supports are installed at two ends of the guide track and used for fixing the guide track. The sliding block is arranged on the guide track and is in clearance fit with the rotating main body. The ball is installed in the sliding block, falls in the grooved tracks and drives the sliding block to be in reciprocating motion axially along the guide track. Sliding friction in the mechanism is changed into rolling friction, friction resistance is small, energy consumption is low, precision is high, the service life is long, and the speed of reciprocating can be controlled accurately.
