Threaded screening machine

Abstract

The invention discloses a threaded screening machine. A first inner groove and a second inner groove are formed in the opposite side walls of a first positioning block and a second positioning block which can be capable of sliding to each other, on a rack, and are matched with the circumferential outer side walls of nuts; a discharging hole of a feeder is formed right above a position between the first positioning block and the second positioning block; a pushing block and a gauge are positioned on both axial sides of the first inner groove and the second inner groove respectively, and are collinear with the axis of an assembly of the first inner groove and the second inner groove; the gauge can rotate in the circumferential direction and can be slidably positioned on the rack in the axial direction; the pushing block can slide in the axial direction and can be locked and positioned on the rack in the circumferential direction; a first power device, a second power device, a third power device and a fourth power device can drive the pushing block, the gauge, the first positioning block and the second positioning block to move; a controller is used for controlling the motions of the first power device, the second power device, the third power device and the fourth power device respectively. The threaded screening machine is high in screening speed, high in production efficiency, high in screening accuracy and low in labor intensity; an operator only needs to operate screening equipment to take an unqualified product out.

Description

technical field [0001] The invention relates to a workpiece detection and screening device, in particular to a thread screening machine. Background technique [0002] In the nut processing industry, it is necessary to detect and screen the thread pitch of nuts. At present, the screening of nuts mainly relies on manual inspection with tooth gauges. The screening speed is slow and labor-intensive, and it is easy for unqualified products to be mixed into the qualified product area. Contents of the invention [0003] In order to make up for the above deficiencies, the present invention provides a thread screening machine, which can quickly complete the screening action of nuts, has high screening speed, high production efficiency, high screening accuracy and low labor intensity of workers. [0004] The technical solution adopted by the present invention in order to solve the technical problem is: a thread screening machine, including the frame, the first and second positioning...
