The utility model discloses with main shaft hole cooperation, form the new clamping strong point, effectively support the barrel, system of processing operates steadily, and short arm turning quality has obtained promoting by a wide margin.
Description
Technical field
The utility model relates to a kind of for the workpiece support device in pipe threading machine spindle hole, for the supporting the use of numerical control pipe thread lathe, belong to field of machining.
Background technology
The continuous exploitation of hiding along with unconventionaloil pool and the extensive use of sub-clustering perforating technology, the market demand of petroleum oil perforation gun also there occurs corresponding transformation, and length 1.3m and following various short arm demand increase day by day.
The distance of conventional pipe threading machine two ends chuck has exceeded the overall length of gun barrel, only have a chuck effectively can clamp gun barrel in turning process, cause running steady, the perforating gun of processing often occur that sealing surface roughness is poor, ellipse and the quality problems such as Wall-Thickness Difference is uneven.In addition, in prior art, lathe also has workpiece support device, such as, supporting frame for workpiece such as lathe shaft disclosed in China Patent Publication No. 202097596U, publication date is 2012-01-04, but existing lathe workpiece bracing or strutting arrangement is not also suitable for pipe threading machine, the clamping not more being suitable for length 1.3m and following various short perforating gun supports.
Summary of the invention
The purpose of this utility model is the problems referred to above overcoming prior art existence, provides a kind of for the workpiece support device in pipe threading machine spindle hole.The utility model coordinates with inner hole of spindle, and form the new clamping strong point, effectively support gun barrel, system of processing operates steadily, and short arm turning quality is significantly enhanced.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of for the workpiece support device in pipe threading machine spindle hole, it is characterized in that: comprise supporting member, sleeve, sliding axle, pull bar and adjusting head, described supporting member and work pieces mate and be fixedly installed on sleeve one end, the sleeve other end arranges adjusting head, sliding axle and pull bar are set in sleeve, sliding axle one end arranges guide frame, the other end is fixedly connected with pull bar one end, the pull bar other end passes adjusting head and is provided with locking nut, sleeve is provided with and forms by sliding axle brought into motion and thread chasing machine spindle hole the expansion mechanism supported.
Described expansion mechanism comprises supporting positive cover and tightening bar, and supporting positive cover is fixedly installed on sleeve outer wall, and tightening bar one end coordinates with thread chasing machine spindle hole, and the other end coordinates with sliding axle through supporting positive cover and sleeve.
The tapered shape of described sliding axle, when pull bar drives sliding axle motion, the conical surface on sliding axle coordinates with tightening bar and drives tightening bar to move.
Described guide frame comprises guider screw and gathering sill, and gathering sill is axially disposed within sleeve, and guider screw one end is slidably arranged in gathering sill, and the other end is fixedly connected with sliding axle.
Employing the utility model has the advantage of:
1, the utility model utilizes expansion mechanism bracing or strutting arrangement and spindle hole to be locked, formed and support, bracing or strutting arrangement rotates with main shaft simultaneously, coordinate with thread chasing machine spindle hole, form the new clamping strong point, effectively support gun barrel, system of processing operates steadily, and short arm turning quality is significantly enhanced.
2, the utility model adopts conical surface location, can adapt to the gun barrel of different inner diameters, can ensure that again gun barrel is coaxial with spindle hole, thus ensures crudy.
3, adopt after the utility model, stood new support lathe main axis hole is built-in, coordinate lathe chuck to realize 3 clampings, system of processing operation is more steady; And Support Position can adjust according to barrel length, applied widely.
4, the utility model is applicable to field of machining, with supporting the use of numerical control pipe thread lathe, and can be applicable to the turnery processing of the similar workpiece of other length except perforating gun processing, realize the turnery processing that length is less than the workpiece of chuck distance, especially in the processing of perforating gun short arm, there is clear superiority.
To sum up, the clamping that the utility model solves length 1.3m and following various short arm supports problem, improve system of processing traveling comfort, serving important function to the raising of crudy, often there is the generation of the quality problems such as poor, the oval and Wall-Thickness Difference of sealing surface roughness is uneven in the perforating gun avoiding processing.Be not only applicable to the processing of various short arm gun barrel, be applicable to other machined field yet, therefore have broad application prospects.
