Description
Technical field
The present invention relates to a kind of survey instrument, especially relate to a kind of fixture of measuring the corresponding pulling force of bolt torque.
Background technology
In vehicle traveling process, the factors such as road conditions are poor, circumstance complication, be easy to cause the phenomenons such as bolt falling, fracture, direct life-threatening safety, so in automobile production, need to be detected bolt corresponding pulling force under even twisting moment, avoid the quality of lot accident to occur.Measure bolt corresponding value of thrust under certain torque condition, current common 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 is connected with sensor, adjust in advance the torque spanner drop-away value, when artificial fastening nut is threaded off to torque spanner, digital display dynamometer is read corresponding value of thrust; Manual mode labour intensity is larger, so mechanical equipment Inspection is arranged, plant equipment is generally automatic detection, need specialized equipment, for example be called " high-strength screw bolt automatic testing instrument " (Granted publication CN 2791624Y), its by axial force test mechanism, add and turn round mechanism for testing, microcomputerized controller, frame and 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 producing in enormous quantities; And two kinds of modes to install, dismantle the mode of bolt to be measured all inconvenient, not easy to operate.
Summary of the invention
Fundamental purpose of the present invention is to provide a kind of fixture of measuring the corresponding pulling force of bolt torque, and it can be used for tension measuring device, measures bolt corresponding value of thrust 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 of measuring the corresponding pulling force of bolt torque, comprise framework, and it is characterized in that: described framework middle part has the handle hole that can hold the torque measurement tool head; The framework bottom is provided with through hole, and the size of this through-hole diameter is between the bar section diameter and head diameter of bolt to be measured; The framework top has the connecting portion that can be fixedly connected on the puller system measuring mechanism.During detection, the bar section of bolt to be measured is through the through hole on framework, then directly or indirectly be fixed to the puller system measuring mechanism, the connecting portion of framework also is fixed to the puller system measuring mechanism, the formation state that suspends, thereafter the torque measurement tool head entangles the head of bolt to be measured in the framework handle hole, and turns to certain moment of torsion, by puller system, reads corresponding pulling force.This structure, bolt to be measured is fixing simple, easy operating, complete detection or sampling observation in production in enormous quantities, all can save the running time, enhances productivity.Because the torque measurement tool head is arranged in the handle hole of framework, bolt to be measured can be in center, stressed comparatively balanced, is beneficial to the raising measuring accuracy; Simultaneously, when the misoperation instrument comes off from bolt head, because framework is limited in the torque measurement tool head in handle hole, avoid injury, improved security.
For further reducing labour intensity, enhancing productivity, as preferably, framework consists of with two closed slit bamboo or chopped woods deployable; Arrange before and after two slit bamboo or chopped woods, be rotationally connected in a side frame setting, the setting of opposite side side frame can be unclamped the locking device with locking.During detection, two secondary frameworks are all launched, by the bar section afterbody of the bolt to be measured nut of screwing on, then be placed in the through hole on top, top two frameworks, then framework is closed and by locking device locking, complete the fixing of bolt to be measured.This structure, simple to operate, save the running time, and the operation that can avoid bolt to pass the framework through hole, be beneficial to the screw thread of protecting bolt.
As preferably, the connecting portion position of described framework is fixed with hook, and hook hook end arranges linking arm to be connected in the puller system measuring mechanism, and this linking arm end is provided with the pin of open slot and pass through openings groove, and the open slot width is adaptive with hook.This structure, pick and place conveniently, and can bear larger moment of torsion.
For preventing or reducing torque measurement process framework distortion, as preferably, it is narrow that described framework is the bottom width top; The frame of framework is wide, and cross section is rectangle, and each frame is with long edge lap.Can there is higher structural strength.
For further saving the running time, as preferably, framework arranges upper and lower two pairs, the inversion of below, and the top of two secondary frameworks is connected in the puller system measuring mechanism from correspondence direction respectively; The head of bolt to be measured and bar section tail end are separately fixed on the framework of upper and lower.Can be fixed on two frameworks bolt to be measured is existing, again framework is linked to the puller system measuring mechanism during measurement, thereby makes 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; Frame middle part, framework bottom has planar structure or boss structure, and 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 whole stress equalization of framework, avoids the phenomenon of canting, can improve measuring accuracy.The medial surface of bolt head to be measured, be resisted against the frame middle part and have planar structure or boss structure, improves the structural strength at this position, increases the service life.
Therefore, the present invention can be used for tension measuring device, measures bolt corresponding value of thrust under certain torque condition; Have simple and reasonable, easy operating, complete detection or sampling observation in production in enormous quantities, all can save the running time, enhances productivity.When framework adopts two deployable with closed slit bamboo or chopped wood structure, can significantly reduce labour intensity, and bolt to be measured picks and places conveniently.
