Safety protection mechanism for composite material polishing machine

Abstract

The invention discloses a safety protection mechanism for a composite material polishing machine. The safety protection mechanism comprises a wire drawing triggering type passive locking mechanism, an unpowered air blowing dust collecting mechanism and a driving protection mechanism. The invention belongs to the technical field of polishing safety protection mechanisms, and particularly relates to a safety protection mechanism for a composite material polishing machine. The invention creatively provides a wiredrawing triggering type passive locking mechanism which comprises a triggering type rebounding guide assembly, a triggering type locking pin assembly, a pre-tightening type swing assembly and a telescopic swing rod assembly, the mechanism is triggered through the movement of the fibers, the response can be quickly made when the fibers are pulled out, and the operation is convenient. According to the technical scheme, whether the current state is a grinding working state or not can be automatically judged, a locking mechanism cannot be triggered even if the current state is touched by mistake in a non-working state, and the technical effect of safety protection in the technical aspect is achieved only through an ingenious mechanical structure under the condition that no electric control or sensor exists.

Description

technical field [0001] The invention belongs to the technical field of polishing safety protection mechanisms, in particular to a safety protection mechanism for a composite material polishing machine. Background technique [0002] In the composite material filled with fiber filaments, in the process of surface polishing, it is easy to grind the surface coating through and hook out the inner fiber filaments. Because the fiber filaments in the composite material are mainly used to strengthen the strength of the composite material Therefore, most of these filaments are not elastic. After being wound into the grinding head, the gap between the grinding heads will be plugged and enlarged due to continuous winding, which will cause irreversible damage to the grinding mechanism. [0003] When the above wrapping occurs, there are mainly two parts of the sanding device that will be damaged: [0004] A: The motor may burn out when the motor is locked, and this problem can be avoided...

AI Technical Summary

Problems solved by technology

[0005] B: Fibers will be entangled in the gap near the grinding spindle. As more and more fibers are entangled, the original gap will be filled and expanded, resulting in deformation of the parts, irreversible damage to the grinding device, and extremely difficult to clean up

[0006] Not only that, but the extremely small-diameter fibers are extremely sharp and can easily scratch the operator
