Description
Technical field
The utility model relates to the pick-up unit field of the upset chuck that a kind of numerically-controlled machine uses, but the precision to the switching mechanism of chuck that relates in particular to that a kind of off-line uses is made the device of detection.
Background technology
Machine for threading is the present numerically-controlled machine of the two chucks of each widely used a kind of special-purpose twin shaft of tame Iron and Steel Production producer, is specifically designed to be oil well pipe, the matching used rifled tube box cupling of tubing and casing by the processing of API standard.Because every precision of this pipe box cupling internal thread is all higher, therefore the every precision of this lathe also there is very high requirement, yet the frequency of utilization of this lathe is very high and cutting load to reach working condition more greatly very poor again, so just directly caused the every precision of switching mechanism and the function of the upset chuck of this machine for threading all to decline to a great extent, it mainly shows as:
1. the processing work qualification rate constantly descends, and rifled tube box cupling off-centre occurs, and the error of main precision indexs such as ovality, tooth depth, tapering, tight distance, right alignment is bigger, makes useless/defect rate rise;
2. matching used carbide-tipped tool waste significantly rises; Cause the raising greatly of production cost;
Therefore to solve the precision problem of above-mentioned converted products, the supplies consumption amount of the qualification rate of raising product, reduction cutter etc., just every precision of the upset chuck that must use this machine tool detects, carry out analysis of science again according to the detection data that obtain, thereby found out the problem the very crux and solved, only in this way can control product quality effectively, reduce consumption, improve economic benefit of enterprises.
Just can carry out the detection of every precision after but conventional upset chuck must be gone up machine, operation is quite loaded down with trivial details had so both expended a large amount of repair times, was difficult to guarantee the accuracy of measurement data again, and needed repeated disassembled and assembled during the generation problem, had improved human cost.
The accuracy detection of this type of band switching mechanism chuck under the prior art does not have special testing tool, therefore after the necessary off-line maintenance of the chuck that overturns, the maintenance, assembly precision to switching mechanism detects very difficult again, basically all be to take the method that detects behind the machine, but as do not reach the accuracy requirement of assembling, also off-line further overhauls, adjusts once more, has so directly caused the repair time of this kind equipment longer, and the precision of upset chuck is recovered, adjustment is wasted time and energy.
In view of the foregoing, now press for a kind of pick-up unit that can after the maintenance of upset chuck off-line, maintenance, get final product fast detecting switching mechanism assembly precision, this device not only can quicklook the ground reading of data, whether the assembly precision of accurately differentiating switching mechanism reaches requirement, simultaneously again can be according to the size and Orientation of reading, judge the direction that adjust and the numerical value of adjustment, can shorten the time of corresponding adjustment greatly, make to use behind the machine of going up and to detect again, adjust.
