Description

Pressing device for planing tool

Technical Field

The utility model relates to the technical field of planing pin processing equipment, in particular to a planing tool compacting device.

Background

The planing and milling processing is a common processing method, is frequently used in the mirror frame processing process of the plate, and generally needs to cooperate with pressing rollers arranged on two sides of the planing tool to work when the planing tool is planing and milling the surface of the glasses plate due to the material specificity of the glasses plate.

In the prior art, the pressing roller provides downward pressure through the spring arranged on the upper part of the pressing roller, and the design structure is simpler, but two problems exist:

1. when the planing tool is replaced, the additional lifting force is required to be increased, and the pressing roller is lifted upwards, so that shielding and interference of the pressing roller and a matched mechanism on the planing tool are avoided. Meanwhile, since a certain time is required for the replacement process, a corresponding lifting force needs to be provided for a long time.

2. The spring is used for providing the pressing force, so that the problem of mechanical fatigue of the spring cannot be avoided, and the spring is maintained in a way of stopping the machine and not stopping the machine generally because the batch for processing the glasses frame is large, so that a part of manpower and material resources are consumed.

And the machine is stopped for maintenance, so that the production efficiency of the equipment is possibly reduced.
