The utility model relates to a pulling force detects anchor clamps, including upward pressing from both sides the cover, pressing from both sides the cover down, go up press from both sides the cover, press from both sides to sheathe in and be equipped with screw hole, lower screw hole, its characterized in that down: go up press from both sides the cover, press from both sides and be equipped with adapter sleeve, lower adapter sleeve in the cover respectively down, the lower extreme of last adapter sleeve be equipped with first screw hole, the upper end of lower adapter sleeve is equipped with the second screw hole, the upper end and last the last screw hole screw -thread fit who presss from both sides the cover of last adapter sleeve, the lower extreme of lower adapter sleeve with press from both sides the lower screw hole screw -thread fit who overlaps down. The present invention uses the technical scheme, the utility model provides a pulling force detects anchor clamps, it can be avoided the raw materials sample and upward press from both sides the cover, press from both sides cover direct contact down, has reduced last screw hole, threaded hole internal thread's wearing and tearing down, long service life moreover, examines time measuring at the raw materials sample to different diameters, only need to be changed go up the adapter sleeve, down the adapter sleeve can, it is more convenient to use.
Description
Technical field
The utility model relates to a kind of pull force calculation fixture.
Background technology
Along with the development of construction machinery industry, high-strength bolt is widely used at machinery industry, and the mechanical property of plant equipment to fastener products is had higher requirement.Bolt adds man-hour requirement and first carries out pull force calculation to its raw material sample, at present, to the pull force calculation fixture of the raw material sample of bolt, include chuck, lower chuck, described upper chuck, lower chuck are provided with upper screwed hole, lower threaded hole, during detection, upper chuck, lower chuck are fixedly connected with tension tester, the upper/lower terminal of raw material sample respectively with upper screwed hole, lower threaded hole threaded engagement.But, this pull force calculation fixture, after long-time use, internal thread in upper screwed hole, lower threaded hole easily weares and teares, make to occur skidding between itself and raw material sample, can only by upper chuck, lower chuck integral replacing if change it, its cost is high, and, install, dismantle inconvenience; In addition when detecting the raw material sample of different-diameter, also need to change different upper chuck, lower chuck, it uses inconvenience.
Summary of the invention
The purpose of this utility model: in order to overcome the defect of prior art, the utility model provides a kind of pull force calculation fixture, it can avoid raw material sample directly to contact with upper chuck, lower chuck, decrease the wearing and tearing of upper screwed hole, lower threaded hole internal thread, long service life, and, when detecting the raw material sample of different-diameter, only need to replace with adapter sleeve, lower joint sleeve, use convenient.
The technical solution of the utility model: a kind of pull force calculation fixture, include chuck, lower chuck, described upper chuck, lower chuck are provided with upper screwed hole, lower threaded hole, it is characterized in that: in described upper chuck, lower chuck, be respectively equipped with upper joint sleeve, lower joint sleeve, the lower end of described upper joint sleeve is provided with the first threaded hole, the upper end of lower joint sleeve is provided with the second threaded hole, the upper end of described upper joint sleeve and the upper screwed hole threaded engagement of upper chuck, the lower end of lower joint sleeve and the lower threaded hole threaded engagement of lower chuck.
Adopt technique scheme, during detection, upper chuck, lower chuck are fixedly connected with tension tester, the upper/lower terminal of raw material sample respectively with the first threaded hole, the second threaded hole threaded engagement, raw material sample is avoided directly to contact with upper chuck, lower chuck like this, decrease the wearing and tearing of upper screwed hole, lower threaded hole internal thread, long service life; And, when detecting the raw material sample of different-diameter, only needing to replace with adapter sleeve, lower joint sleeve, using convenient.
Further setting of the present utility model: the upper end of described upper joint sleeve is provided with upper limit boss, conflict in described upper limit boss and the upper surface of upper chuck, the lower end of described lower joint sleeve is provided with lower limit boss, conflicts in the lower surface of described lower limit boss and lower chuck.
Adopt above-mentioned further setting, the upper limit boss, the lower limit boss that arrange, can prevent from producing between chuck and upper joint sleeve, between lower chuck and lower joint sleeve skidding, and, the pressure of upper screwed hole, lower threaded hole internal thread tooth can be alleviated, extend its serviceable life.
Setting further more of the present utility model: the upper end of described upper screwed hole is provided with cut, is provided with the upper chamfering matched with upper groove between described upper limit boss and upper joint sleeve.
Adopt and above-mentionedly to arrange further again, the upper groove of setting, upper chamfering, can prevent from reducing the wearing and tearing between upper chuck and upper limit boss, upper joint sleeve, extend its serviceable life.
Further setting more of the present utility model: the lower end of described lower threaded hole is provided with lower cut, is provided with the lower chamfering matched with lower groove between described lower limit boss and lower joint sleeve.
Adopt and above-mentionedly further to arrange again, the lower groove of setting, lower chamfering, can prevent from reducing the wearing and tearing between lower chuck and lower limit boss, lower joint sleeve, extend its serviceable life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model specific embodiment.
