Nailing machine tightening device

Abstract

The invention discloses a nailing machine tightening device, and belongs to the technical field of mechanical automation equipment. The device comprises a driving electric cylinder, the driving electric cylinder is connected with a pressing block and a supporting block, a mounting plate is arranged on the supporting block, a buffer spring is arranged between the mounting plate and the pressing block, the mounting plate is mounted on a screwdriver, a distance sensor is mounted on the lower surface of the mounting plate, and an adjusting screw is arranged below the distance sensor. The tightening device has the advantages that nails are taken in a vacuum adsorption mode, a tool bit axially rotates when moving downwards to take the nails, nail heads are driven into a crosshead of the tool bit when the nails are sucked, the cooperative relation is good in the nail taking and tightening process, the buffer spring functions in buffering for nailing, hard contact of the tool bit and screws is avoided, damage to the nail heads and threads is avoided, and the distance a between the crosshead of the tool bit and the tightening surface of each screw is monitored by detecting the distance b between the distance sensor and an adjusting screw to verify whether the screws are fastened in place or not.

Description

technical field [0001] The invention relates to a screw tightening device, which belongs to the technical field of mechanical automation equipment. Background technique [0002] The automatic nailing machine can efficiently complete the nailing task and has received wide acclaim. However, the existing nailing equipment still has the following problems: it is impossible to monitor whether the screw is tightened in place in real time, and manual inspection is required, which wastes labor costs; there is no buffer protection for the tightening cutter head, and the service life is low. It will destroy the thread of the screw; the traditional nailing machine's tightening mechanism does not work well with automatic nail removal and tightening. Contents of the invention [0003] In order to solve the defects in the prior art, the object of the present invention is to provide a tightening device for a nailing machine, which can automatically verify whether the screw is fastened i...
