Description

The automatic casing cutter bed

The utility model relates to a kind of automatic casing cutter bed, belongs to conveyer carrying roller or other pipe part are cut off the also Special Automaticization equipment of two chamfers.

Existing to pipe part cut off, the processing of chamfering, generally carry out at universal machine tools or on special frock, by artificial loading and unloading and measure length, manually chamfering is carried out in tool changing again after clamping or hydraulic clamp, the cut-out, need secondary operations, particularly to long mother tube clamping difficulty, need to cut off in advance, this method labour intensity is big, efficient is low, processing length is measured control one by one by the operator, therefore is not suitable for producing in enormous quantities.

The purpose of this utility model is to overcome the weak point in the background technology, and provide a kind of rational in infrastructure, labour intensity is little, automatic cut-to-length guarantees precision, the automatic casing cutter bed of continuous and automatic processing.

The purpose of this utility model is achieved in that it comprises lathe bed, main spindle box, knife rest, adapter frame, electrical system and hydraulic system, and main spindle box is fixed on a side of lathe bed; Knife rest is two, and angle is fixed on the end face of main spindle box one side at 90 degrees to each other; Main spindle box knife rest one side is provided with sizing mechanism of reinforcing; The main spindle box opposite side is provided with feeding trolley.

The purpose of this utility model can also reach by following technical measures: sizing mechanism of reinforcing is made up of scale seat, end cover, scale oil cylinder, the scale oil cylinder is fixed on the scale seat, the scale seat places on the bed ways, piston and piston rod are arranged in the oil cylinder, the piston rod two ends are connected with travel switch with end cover respectively, are provided with mother lead screw in the scale seat and match with leading screw on the lathe bed.Feeding trolley is made up of base, reductor and road wheel, motor, live center, live center, reductor, motor are fixed on the base, motor links to each other with reductor by belt, reductor links to each other with the road wheel driving shaft by belt, and 4 road wheels under the base place on two parallel vehicle guides.

The utility model compared with prior art has following advantage:

1. rational in infrastructure, easy to operate;

2. the feeding trolley of walking on guide rail matches with sizing mechanism of reinforcing, can realize self-feeding, automatic gauging, afterwards by electrical system and HYDRAULIC CONTROL SYSTEM, make clamping device clamp processed pipe automatically, knife rest autofeed and withdrawing, the processing rear fixture unclamps automatically, moves in circles, thereby has realized continuous, automation processing.High efficiency has alleviated labour intensity simultaneously.
