Screw mounting mechanism capable of positioning automatically

Abstract

The invention discloses a screw mounting mechanism capable of positioning automatically. The screw mounting mechanism comprises a base, a rotary block fixing seat arranged on the base, and a screw channel arranged in front of the rotary block fixing seat; a screw receiving rotary block is arranged at the top of the rotary block fixing seat; an arc-shaped through groove connected with the screw channel is formed at one end of the screw receiving rotary block, and the other end is connected with the base through an extension spring; a hollow screw suction rod is arranged above the screw receiving rotary block and is fixed on a liftable screw locking manipulater; a vacuum pump is connected with the internal cavity of the screw suction rod; a screwdriver used for tightening screws is arrangedin the screw suction rod; a through hole is formed on the base and at the position corresponding to the screw receiving rotary block; and the screw suction rod, the arc-shaped through groove and the through hole are positioned in the same vertical line. the screw mounting mechanism capable of positioning automatically solves the problems of screw conveying and screw positioning when screws are mounted automatically, realizes full automatic positioning and fast mounting of screws, saves manpower and greatly improves the efficiency of mounting screws on workpieces.

Description

technical field [0001] The invention relates to a screw loading mechanism, in particular to an automatic positioning screw loading mechanism. Background technique [0002] At present, electric or pneumatic screwdrivers are commonly used to tighten screws on industrial production lines. Although this type of power screwdriver has the advantage of simple structure, it still needs to be operated by hand, which cannot realize automatic production and low work efficiency; when the scale of production When it is large, a large number of workers are required to perform the operation of screwing, which increases production costs. [0003] The working principle of some existing automatic screwing devices is that the screw is first delivered to the guide hole above the screw hole, and then the manipulator is used to control the electric batch to tighten the screw, which realizes the automatic operation of the screwing process. But these devices are only applicable to the situation th...

Problems solved by technology

However, these devices are only suitable for the situation where there is a guide hole above the screw hole. When there is no guide hole above the screw hole or self-tapping screws need to be installed, it is difficult to realize the automatic positioning and tightening of the screw.
