Fixture for chamfering machine

Abstract

The invention discloses a fixture for a chamfering machine. The fixture for the chamfering machine comprises a rotary lifting rod, a transverse rod, a hanging rod, a vacuum sucker, a fixing disk, a rotary shaft and a third motor. The rotary lifting rod is liftable in height and capable of rotating. The transverse rod is fixedly arranged at the top of the rotary lifting rod and the hanging rod is nested at the bottom of the transverse rod by a bearing. The vacuum sucker is fixedly arranged at the bottom of the hanging rod. The fixing disk is arranged right below the vacuum sucker in an axial manner and the bottom of the fixing disk is fixedly connected with the rotary shaft. The rotary shaft is driven to rotate by the third motor. The external diameter of the fixing disk and the external diameter of the vacuum sucker are both less than the external diameter of glass to be chamfered. According to the fixture, the clamped glass to be chamfered is capable of rotating automatically, so that all the circumferential surfaces of the glass to be chamfered can be chamfered uniformly and the chamfering efficiency is high.

Description

technical field [0001] The present application relates to an auxiliary detection device for pharmaceutical packaging, in particular to a jig for chamfering machines. Background technique [0002] Packaging materials that are in direct contact with drugs need to meet certain standards. For example, in the "Compilation of Packaging Materials and Container Standards for Direct Contact with Drugs", it is stipulated that the average linear thermal expansion coefficient of pharmaceutical glass containers is about 3.3*10 -6 KA -1 made of borosilicate glass. That is to say, when purchasing or designing and developing glass bottles that are in direct contact with medicines, it is necessary to measure and analyze the average linear thermal expansion coefficient of the glass bottles to identify glass materials and select medicine bottles that are compatible with medicines. [0003] When conducting the average linear thermal expansion coefficient test or component analysis of glass me...

AI Technical Summary

Problems solved by technology

Sanding is laborious and the chamfers are uneven

Hand-held glass is polished on a grinding wheel, which requires high manual skills and is not safe. The glass is small and difficult to hold, and may wipe hands. In addition, the glass will splash during grinding, which may also cause harm to the human body.
