Description
Technical field
The present invention relates to a kind of tube cutting machine bed annex, particularly a kind of cutting torch floating installation of pipe cutting machine bed.
Background technology
In tube cutting machine bed when work,, workpiece need be rotated motion, and cutting torch moves, thereby realizes the cutting of tubing.According to the requirement of cutting technique, the distance between cutting torch and the pipe outer surface is a steady state value, could guarantee cut quality and cutting accuracy like this.Because tubing just allows certain geometrical deviation (as the profile deviation from circular from) when dispatching from the factory, like this tubing when rotated, the outer surface of tubing can be fluctuated, and the individual desirable circle that differs.Causing between pipe outer surface and the cutting torch distance can be suddenly big or suddenly small, be a steady state value.In order to guarantee cutting accuracy, so just require when work, need the distance between workpiece and the cutting torch to be detected, compensate then, thereby guarantee that distance is a steady state value between workpiece and the workpiece when work.The mode that detects on the tube cutting machine bed now and compensate has two kinds: a kind of switch that is to use carries out pre-detection to cutting track, and a kind of is the real-time detection of adopting near switch.This dual mode all has weak point at present:
1. pre-detection compensation way: before the tubing cutting, cutting track is carried out the multiple spot analog detection, import electrical system and compensate detecting data, and then cut by touch switch or optoelectronic switch.Because cutting track will walk twice, greatly reduce working (machining) efficiency like this.And its offset is according to detecting the data of each point, carries out at whole track that interpolation operation forms, thereby has certain deviation on partial data.2. detect compensation way in real time: adopt capacitive approach switch that workpiece is detected, its principle is cutting head and the surface of the work positive and negative level as capacitor, cutting head can cause changes in capacitance to the variable in distance of surface of the work, change and judge that cutting head changes to the height distance of surface of the work, compensates by electrical system and adjusts the height distance of cutting head to surface of the work by detecting capacitor.Its structure is passed through to detect changes in capacitance in cutting process, and is adjusted the distance between cutting torch and the surface of the work in real time for capacitor induction type to be installed near switch in the one or both sides of cutting torch.At first, the error of this detection is not to the cut point place, but in the error of installing near the switch place, if installation is closer near the distance between switch and the cutting torch, it is not very violent that surface of the work changes, and can be similar to the error of thinking the cut point place.Secondly this detection deal with data is many, and needs to handle in real time, and this requires high to electrical system, otherwise because the hysteresis that in time has that data are handled takes place, causes the inaccurate of cutting.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of cutting torch floating installation of pipe cutting machine bed is provided, makes its height that can regulate cutting torch in real time, the distance between assurance cutting torch head and the pipe outer surface is a steady state value.
In order to solve the problems of the technologies described above, the utility model comprises holder and floating part, floating part comprises support and the universal ball and the cutting torch that are arranged on the support, support can slide up and down and is arranged on the holder, during duty, fit in universal ball and workpiece top, the head of cutting torch is higher than the minimum point of universal ball.The head of cutting torch and the perigee distance of universal ball are preferably the optimum distance of cutting torch apart from surface of the work.
In order to improve the sensitivity that floating part moves up and down, be connected with the balancing spring that hangs floating part between described holder and the floating part.
In order to be suitable for cutting the workpiece of different wall, described floating part includes the difference in height governor motion of the minimum point of cutting torch head and universal ball.
For the ease of producing and installing, described support comprises gusset piece, fork and depression bar, described holder is the guide rail mount pad, gusset piece is connected with the guide rail mount pad by the line slideway auxiliary that vertically is provided with, fork and depression bar are arranged on the gusset piece, cutting torch is arranged on the fork, and universal ball is arranged on the depression bar.
In order to improve the accuracy that detects and compensate, described depression bar has two, be separately positioned on the both sides of fork, described height difference regulating device is for regulating the arrangement for adjusting height of the relative gusset piece of depression bar, one end of depression bar is connected with gusset piece by arrangement for adjusting height, respectively is provided with a described universal ball on each depression bar.
Can drive the drive unit that fork rotates in order to realize in the cutting workpiece being beaten the groove operation, to be fixed with on the described gusset piece, the head of cutting torch is positioned on the fork pivot center.Can guarantee cutting torch in swing process, the cutting torch head is a fixed point, and the variation with pendulum angle does not change.
For the range of movement that prevents to damage gusset piece and limit gusset piece, the bottom of described guide rail mount pad is fixed with fixed block, and anti-collision block is installed on the fixed block, and anti-collision block is positioned at the below of gusset piece.
For the ease of detecting the original position of floating part, on the described gusset piece sensor block is installed, on the described guide rail mount pad position sensor is installed.
The beneficial effects of the utility model are: this reality is novel to be driven cutting torch by the universal ball of fitting with the workpiece top and fluctuates, can regulate the height of cutting torch in real time, realize cutting torch that real-Time Compensation brings because of the out-of-roundness of tubing variable in distance amount to pipe outer surface, distance between assurance cutting torch and the pipe outer surface is a steady state value, and compensation speed is fast, can not produce hysteresis.
And the utility model also has the following advantages 1. because the balancing spring effect is arranged, and has offset most of weight of floating part, therefore on both direction up and down, all can easily detect and compensate, and has realized omnibearing compensation.And need not in electrical system, to calculate compensation, less demanding to electrical system not only, and also the speed of compensation is faster, can not produce hysteresis.
2. owing to be frame for movement, the high temperature that depression bar and universal ball are afraid of generation when cutting does not cut slag, thereby the distance between itself and the cutting torch, more than near near the distance between switch and the cutting torch, thus more even better than original real-time detection on compensation precision.And floating part moves on line slideway auxiliary, has superior dynamic response performance, thereby can accomplish to detect in real time accurately and compensation.
3. owing to guaranteed the distance of cutting torch and surface of the work, the cutting surface quality of workpiece is good, the current interruption phenomenon can not occur.
4. owing in the swing process, the cutting torch head is constant for fixed point, thereby when carrying out the groove cutting, the distance of cutting torch and workpiece outer surface is constant, thereby has guaranteed high-quality groove cutting accuracy.
5. simple in structure, easy to operate, with low cost, applied range, cutting efficiency height.
