Rotary opening and closing mechanism

Abstract

The invention discloses a rotary opening and closing mechanism. The mechanism includes a first tooling, a second tooling, a linear power source, an extension rotary shaft and an axial cam; the extension rotary shaft can be rotatably connected to the front end of the linear power source, and successively passes through the first tooling and the second tooling; the first tooling is located at the position matching the extension rotary shaft, and can rotate relative to the extension rotary shaft; the second tooling is fixed on the extension rotary shaft so as to move along with the extension rotary shaft in an axial direction; the axial cam is arranged at the position fitting with the second tooling so that the second tooling can rotate along axis through the cooperation with the axial cam when moving in the axial direction; and an alignment guide pin is eccentrically connected between the second tooling and the first tooling in the axial direction, so that the second tooling can drive the first tooling to rotate synchronously when rotating. The mechanism uses linear power to realize one-time accomplishment of material distributing (namely pulling apart) in the mechanism, and therefore, costs can be greatly reduced, and the space occupied by the mechanism can be shrunk.

Description

technical field [0001] The invention relates to the technical field of automatic mechanical equipment, in particular to a swivel opening and closing mechanism. Background technique [0002] With the continuous improvement of automation reliability requirements, mechanical linkage mechanism is worthy of vigorous promotion. The accuracy of the two stations is not difficult to control and can directly improve the efficiency of the equipment. At present, the double-station production equipment is widely used. The double station of automatic mechanical equipment does not need to be separated into two stations by the material distribution mechanism when feeding, so that the operation can be divided into stations. Since the automatic feeding of some products cannot achieve a suitable orientation and orientation, at this time the product must be rotated before it can be loaded to the operating station, that is to say, it needs a material distribution and a rotation. The existing au...

Problems solved by technology

Since the automatic feeding of some products cannot achieve a suitable orientation and orientation, at this time the product must be rotated before it can be loaded to the operating station, that is to say, it needs a material distribution and a rotation. The existing automation The method adopted by mechanical equipment is to add a transfer mechanism, and then add a conveying process, that is to say, it is realized by two independent mechanisms, one is a pulling mechanism and the other is a rotating mechanism, resulting in a large volume and high cost. disadvantages
