Automatic structure for scissor type clamp

Abstract

The invention relates to an automatic clamp, in particular to a clamp of a scissor type structure. The invention provides another scissor type clamp grabbing and releasing mechanism, a hook-shaped structure is arranged on a scissor arm 1, a sliding groove is formed in a connecting rod 3, a pin 5 capable of sliding in the sliding groove is additionally arranged, and automatic opening and closing of the clamp are achieved through one-hand lifting and releasing actions. According to the structure, the scissor arm 1 and the connecting rod 3 can be directly formed by means of laser cutting, additional automatic devices do not need to be added, the operation process steps are completely consistent with those of an existing automatic clamp, and are not influenced by the size of a scissor type clamp, so that wide universality and economical efficiency are achieved.

Description

technical field

[0001] The invention relates to a lifting fixture, in particular to a fixture with a scissor structure. Background technique

[0002] At present, a large number of scissor fixtures are used to clamp workpieces in industries such as processing, assembly, and logistics at home and abroad. These clamps are generally equipped with a set of devices for controlling the opening and closing of the clamps to improve work efficiency. When operating the fixture, there is no need for personnel to touch or open the fixture, and the automatic opening and closing of the fixture is realized directly by using the self-weight of the fixture and the contact with the upper surface of the workpiece or the ground. The flow sequence during operation is: put down the fixture (to the workpiece) - lift the fixture (fixture clamping) - put down the fixture (to the target area) - lift the fixture (release the fixture). The sequence of "putting-lifting-putting-lifting" can be repeated ...
