Vibrating disc capable of automatically identifying front and back surfaces of gasket

Abstract

The utility model discloses a vibrating disk capable of automatically identifying front and back surfaces of a gasket, which comprises a vibrating disk provided with a discharge port, a vibrating motor is mounted at the bottom of the vibrating disk, the output end of the vibrating motor is fixedly connected with the vibrating disk, and an obliquely arranged track surrounds the discharge port at the outer end of the vibrating disk. A protrusion for bearing the bottom of a gasket in a vertical state is arranged at the bottom of the rail, the width of the protrusion is equal to the thickness of the gasket, an identification notch is formed in the protrusion, the width of the identification notch is one third of the thickness of the gasket, and the tail end of the rail is connected with a horizontal supporting plate. And an auxiliary guide strip for adjusting the gasket to be in a horizontal state is arranged between the tail end of the rail and the horizontal supporting plate. When the front face of the gasket is attached to the track to be conveyed, due to the fact that the front face of the gasket is an arc face and the contact area between the lower end of the gasket and the protrusion is small, when the gasket passes through the identification notch, the gasket can fall off from the identification notch due to the fact that the width of the protrusion is decreased and the contact area between the protrusion and the bottom of the gasket is decreased. Therefore, the gaskets are ensured to enter the horizontal supporting plate in a horizontal state with the front faces facing upwards, accurate output of the gaskets is facilitated, and the follow-up automatic gasket penetrating efficiency can be improved.

Description

Technical Field

[0001] This utility model relates to the field of automatic gasket insertion for bolts in rail transit vehicle manufacturing, and more particularly to a vibratory feeder that automatically identifies the front and back of the gasket. Background Technology

[0002] The assembly of rail vehicles largely relies on manual installation. For example, inserting washers into bolts is mainly done manually, requiring significant manpower and time to meet the needs of the production site. Introducing a "bolt and washer insertion" assembly machine can free up the productivity of these workers, enabling automated and intelligent bolt and washer insertion assembly, allowing for immediate start-up and use.

[0003] Non-customized equipment on the market generally uses smaller bolts and washers, mainly for bolt tightening in small equipment, and does not have the function of automatically applying thread lubricant. Generally speaking, non-customized washer insertion equipment only has one combination of "bolt, spring washer, flat washer" insertion mode, and rarely has the function of identifying the correct orientation of the washer.

[0004] Reference Figure 1 , Figure 2 Currently, gaskets are generally produced by stamping. The stamped gaskets 7 have different front and back sides. The front side 71 is a large-diameter arc surface, and the back side 72 is a small-diameter flat surface. The two are connected by a bevel 73. During normal production or use, it is necessary to distinguish between the front and back sides. If the front and back sides are identified and screened manually one by one, the efficiency is low, the time is long, and a lot of manpower and time will be wasted, which will bring inconvenience to production or use.
