Description
Technical field
The present invention relates to a kind of survey instrument, especially relate to a kind of fixture measuring the corresponding pulling force of bolt torque.
Background technology
In vehicle traveling process, the factors such as road conditions are poor, circumstance complication, are easy to cause the phenomenon such as bolt falling, fracture, direct life-threatening safety, so in automobile production, need the pulling force corresponding under even twisting moment to bolt to detect, avoid quality of lot accident to occur.Measure the value of thrust that bolt is corresponding under certain torque condition, common at present have manual mode and mechanical system, manual mode generally detects with axle power meter, the frame of axle power meter is fixed in ground, tested nut and sensor series, adjust torque spanner drop-away value in advance, when artificial fastening nut is threaded off to torque spanner, digital display dynamometer reads corresponding value of thrust; Manual mode labour intensity is larger, so there is mechanical equipment Inspection, plant equipment is generally automatic detection, need specialized equipment, such as " high-strength screw bolt automatic testing instrument " (Authorization Notice No. CN 2791624Y) by name, its by axial force test mechanism, add turn round mechanism for testing, microcomputerized controller, frame form, axial force test mechanism by bearing axle power frame, bear screw rod, pulling force sensor, attachment bolt, axle power frame, front bearing plate and locating device form, add turn round mechanism for testing by sleeve, square shaft, torque sensor, bearing seat, add and turn round driver and form.Above-mentioned manual mode labour intensity is large, production efficiency is lower, and mechanical system needs specialized equipment, and cost is high, and production efficiency is also not high enough, is difficult to adapt to a large amount of detections in production in enormous quantities; And the mode that bolt to be measured was installed, dismantled to two kinds of modes is all inconvenient, not easy to operate.
Summary of the invention
Fundamental purpose of the present invention is to provide a kind of fixture measuring the corresponding pulling force of bolt torque, and it can be used for tension measuring device, measures the value of thrust that bolt is corresponding under certain torque condition; Cost is low, easy to operate, production efficiency is high.
Above-mentioned technical matters of the present invention is mainly solved by following technical proposals: a kind of fixture measuring the corresponding pulling force of bolt torque, comprises framework, it is characterized in that: have the handle hole that can hold torque-measuring tools head in the middle part of described framework; Be provided with through hole bottom framework, the size of this through-hole diameter is between the bar portion diameter and head diameter of bolt to be measured; Framework top has the connecting portion that can be fixedly connected on puller system measuring mechanism.During detection, the bar portion of bolt to be measured is through the through hole in framework, then puller system measuring mechanism is directly or indirectly fixed to, the connecting portion of framework is also fixed to puller system measuring mechanism, form suspended state, thereafter torque-measuring tools head entangles the head of bolt to be measured in framework handle hole, and turns to certain moment of torsion, reads corresponding pulling force by puller system.This structure, bolt to be measured is fixing simple, and be easy to operation, complete detection or sampling observation in production in enormous quantities, all can save the running time, enhance productivity.Because torque-measuring tools head is arranged in the handle hole of framework, bolt to be measured can be in center, stressed comparatively balanced, is beneficial to raising measuring accuracy; Meanwhile, when misoperation instrument comes off from bolt head, because torque-measuring tools head is limited in handle hole by framework, avoid injury, improve security.
For reducing labour intensity further, enhancing productivity, as preferably, framework is made up of with two closed slit bamboo or chopped woods deployable; Arrange before and after two slit bamboo or chopped woods, arrange at a side frame and be rotationally connected, opposite side side frame arranges the locking device that can unclamp with locking.During detection, two secondary frameworks are all launched, nut that the bar portion afterbody of bolt to be measured is screwed on, then be placed in the through hole in top, top two framework, then framework is closed and locking device is locked, namely complete the fixing of bolt to be measured.This structure, simple to operate, save the running time, and bolt can be avoided to pass the operation of framework through hole, be beneficial to the screw thread of protection bolt.
As preferably, the connecting portion position of described framework is fixed with hook, and hook hook end arranges linking arm to be connected to puller system measuring mechanism, and this linking arm end is provided with the pin of open slot and pass through openings groove, and open slot width is adaptive with hook.This structure, picks and places conveniently, and can bear larger moment of torsion.
For preventing or reducing the distortion of torque measurement process framework, as preferably, it is narrow that described framework is bottom width top; The frame of framework is wide, and cross section is rectangle, and each frame is with long edge lap.Higher structural strength can be had.
For saving the running time further, as preferably, framework arranges upper and lower two secondary, the inversion of below, and the top of two secondary frameworks is connected to puller system measuring mechanism from correspondence direction respectively; Head and the bar portion tail end of bolt to be measured are separately fixed in the framework of upper and lower.Can be fixed in two frameworks by existing for bolt to be measured, during measurement, again framework is linked to puller system measuring mechanism, thus make the fixing operation of bolt to be measured easier, in batch detection, significantly reduce the running time, enhance productivity.
For improving measuring accuracy, as preferably, described framework is symmetrical closing structure; Have planar structure or boss structure in the middle part of frame bottom framework, through hole is located on this planar structure or boss structure.Framework adopts closing structure, can have higher structural strength; Symmetrical structure is beneficial to bolt to be measured and the overall stress equalization of framework, avoids the phenomenon of canting, can improve measuring accuracy.The medial surface of bolt head to be measured, is resisted against in the middle part of frame and has planar structure or boss structure, improve the structural strength at this position, increase the service life.
Therefore, the present invention can be used for tension measuring device, measures the value of thrust that bolt is corresponding under certain torque condition; Have simple and reasonable, be easy to operation, complete detection or sampling observation in production in enormous quantities, all can save the running time, enhance productivity.When framework adopts two deployable and closed slit bamboo or chopped wood structure, significantly can reduce labour intensity, and bolt to be measured picks and places conveniently.
