Residue cleaning and defective product screening device for hexagonal nut production

Abstract

The invention provides a residue cleaning and defective product screening device for hexagonal nut production, and relates to the technical field of part machining. The problems that a defective product left in a screening box after screening is easily clamped in a screening hole and is inconvenient to take out quickly for collection, and high-frequency fine vibration cannot be synchronously realized in the up-down vibration process through structural improvement are solved. The residue cleaning and defective product screening device for hexagonal nut production comprises a main body seat andstress blocks, and a sliding structure is welded on the main body seat. A shifting block B is welded with two sliding seats B, and the bottom end surface of the shifting block B is in contact with thebottom end surface of a screening box body; and the front end face of the shifting block B is of an inclined structure, and the inclination angle is 60 degrees, so that when the shifting block B moves along with the sliding seats B and a cleaning block for cleaning, the shifting block B can jack back a nut partially exposed out of the screening hole through the inclined face of the front end face, and thus the phenomenon that the cleaning block is stuck in the moving process is avoided.

Description

technical field [0001] The invention belongs to the technical field of parts processing, and more specifically relates to a residue cleaning and defective product screening device for the production of hexagonal nuts. Background technique [0002] A nut is a nut, a part that is screwed together with a bolt or a screw for fastening. It is a necessary component for all manufacturing machinery; with the promotion of mechanization, the demand for nuts increases. With the development of the industry, the output of nuts is also increasing. [0003] For example, the application number: CN201410681031.8, the invention discloses a simple nut screening machine, which includes a frame and a screening plate. The screening plate is composed of an upper screening plate, a lower screening plate and two connecting plates, and the two connecting plates and The upper screening plate and the lower screening plate form a hollow flat cuboid structure, the two ends of the hollow part are respect...

Problems solved by technology

[0007] In order to solve the above technical problems, the present invention provides a residue cleaning and defective product screening device for the production of hexagonal nuts, to solve the existing problem that the defective products or nuts with too large burrs will be damaged after screening in the existing device. Remaining in the screening box, and the defective products remaining in the screening box are easy to get stuck in the sieve hole, which is inconvenient to quickly take out for collection, but can switch between feeding and working status by opening and closing the cover plate through structural improvement In the process of automatic realization of the rapid removal of these defective products stuck in the sieve holes, at the same time, the collection of residues is realized synchronously; moreover, although the existing device can also realize the upper and lower screening by means of vibration, it cannot pass the structure Improvement on the problem of synchronously achieving high-frequency fine vibrations during the up-and-down vibration process to achieve the purpose of improving the screening effect
