Abstract
The invention discloses a wall thickness measuring device by tracking for drilling an inner hole of a drill collar, which is a device matched with a deep hole drilling and boring machine. The device comprises a guide rail, a thickness measurer, a trolley and a rod, wherein the guide rail is vertically arranged on one side of a deep drilled and bored hole; a workpiece clamped by the deep hole drilling and boring machine is parallel to the guide rail; the thickness measurer is vertically arranged on the top of the trolley through the rod; the trolley and a drill move along the guide rail at a synchronous speed; probes of the thickness measurer are arranged on claws of an extension arm, and the central connecting line of the two probes is overlapped with the radial line of the workpiece; and the probes are axially arranged 15 to 30mm behind the cutting edge on the top of the drill so as to improve the measurement accuracy. The device can measure the wall thickness by tracking when the hole is drilled, and sends out warning in time when discovering deviation, is convenient to rectify the deviation because of small deviation so as to reduce rectification man-hour and avoid scrapping. Furthermore, shutdown inspection is not required in drilling, auxiliary man-hour is greatly reduced, and the production efficiency is improved. The wall thickness measuring device is particularly suitable for mass production.
Description
Technical field
The present invention relates to a kind of length-measuring appliance, specifically, the present invention relates to a kind of drilling drill collar bore and follow the tracks of survey wall thickness device.
Background technology
The drill collar that is used for the deep-well petroleum drilling and mining is a kind of long tube member, its long 8m～10m, and external diameter Φ 160mm～220mm, diameter of bore is at 40mm～90mm.The key technology of making drill collar is the drilling endoporus, because drill bit is cantilever-shaped during the drilling of deep hole prone position, difficulty of processing is big, is prone to deflection takes place and produces waste product or defective work.Prior art takes interrupted the parking to detect the way of wall thickness in drilling process, so that in time take measures to rectify a deviation to borehole throw, thereby avoids producing waste product.Although this kind passive type detection method can effectively be pinpointed the problems, promptness is relatively poor, in case the deviate stool is strengthened back correction difficulty.In addition, the frequent detection of stopping must reduce production efficiency.Generally speaking, prior art is not suitable for producing in enormous quantities.
Summary of the invention
The present invention is primarily aimed at the deficiency of prior art, proposes a kind of drilling drill collar bore that dynamically, detects in real time and follows the tracks of and survey the wall thickness device, and this apparatus structure is simple, reliable measurement; Can in the very first time, find borehole throw; Because of the departure of generation is few, so correction avoids producing waste product easily.
The present invention realizes technical goal through following technical proposals.
The drilling drill collar bore is followed the tracks of and is surveyed the wall thickness device, and it is the corollary apparatus of gun drilling boring machine, and this device comprises guide rail, calibrator, dolly and bar.Said guide rail vertically is installed in gun drilling boring machine one side, and the workpiece of gun drilling boring machine clamping is parallel with guide rail.At the dolly end face, dolly and drill bit keep synchronizing speed to move along guide rail to said calibrator by the bar vertical support.Its improvements are: the probe of calibrator is installed in the claw of overhanging arm; Overhanging arm is a cantilever member; The claw type of its end is the symmetrical openings fork; Two respectively vertical probes of installing in fork limits, the line of centres of two probes overlaps with the workpiece RADIAL, and the axial installation site of popping one's head in is located at 15mm～30mm behind the chisel edge cutting edge.
In the said structure, the overhanging arm claw of calibrator is a demountable structure, and superposed pawl is a movable part, and this pawl links into an integrated entity with bolt and overhanging arm.
The present invention compared with prior art has following good effect:
1, apparatus structure is simple, reasonable, easy to use;
Dynamic tracking measurement wall thickness when 2, holing, in case find deviation, correction had in time both reduced the man-hour of rectifying a deviation easily, also avoided scrapping;
3, tracking measurement need not made parking checking, greatly reduces unproductive time, enhances productivity, and helps producing in enormous quantities.
Description of drawings
Fig. 1 is the present invention's structural representation during measuring workpieces on the gun drilling boring machine.
Fig. 2 is a structural representation of the present invention.
The specific embodiment
According to shown in the accompanying drawing and combine embodiment, the present invention is described further below.
Shown in Figure 1 is the present invention's structural representation during measuring workpieces on the gun drilling boring machine.Gun drilling boring machine 1 clamping workpiece 7 among the figure, drill bit 3 pierces from workpiece 7 front ends, and the present invention is positioned at gun drilling boring machine 1 left side, and it comprises guide rail 2, calibrator 4, dolly 5 and bar 6, and guide rail 2 is parallel with the main shaft of gun drilling boring machine 1.At dolly 5 end faces, dolly 5 keeps synchronizing speed to move along guide rail 2 with drill bit 3 to said calibrator 4 by bar 6 vertical support.The probe 4.4 of calibrator 4 is installed in the claw of overhanging arm 4.1 among the present invention, and overhanging arm 4.1 is a cantilever member, and the claw type of its end is the symmetrical openings fork; Two vertical respectively probes 4.4 of installing in fork limit; The line of centres of two probes 4.4 overlaps with workpiece 7 RADIALs, the long 9.6m of present embodiment workpiece 7 drill collars, and diameter is 200mm; Endoporus is 76.2mm, and the opening fork mouth of overhanging arm 4.1 ends leaves monolateral gap 2.5mm with workpiece 7.In order to ensure the probe measurement precision, the 4.4 axial installation sites of will popping one's head in are located at 20mm behind the drill bit 3 front end cutting edges.The present invention installs for ease of workpiece 7; And the outer wall quality of fit of the opening of overhanging arm 4.1 ends fork and workpiece 7; The opening fork of overhanging arm 4.1 ends is designed to demountable structure, and superposed pawl 4.3 is movable parts, and pawl 4.3 usefulness bolts 4.2 link into an integrated entity with overhanging arm 4.1.
The present invention through tracking active wall-thickness measurement, in case find that deviation just in time gives a warning, is convenient to the back correction because of departure less when boring, both reduced the man-hour of rectifying a deviation, and also avoids scrapping.In addition, when boring, need not make parking checking, significantly reduce unproductive time, enhance productivity.
