Abstract
The invention discloses a mechanism used for detecting bolt stress. The mechanism is characterized in that the mechanism comprises an upper joint clamping plate, a lower joint clamping plate, a bolt, an upper fixed block and a lower fixed block, the upper end of the bolt is installed in the upper fixed block, the lower end is screwed in the lower fixed block, and the upper fixed block and the lower fixed block are installed in the upper joint clamping plate and the lower join clamping plate respectively. The mechanism used for detecting bolt stress can accurately measure the maximum destruction breakage tension which can be born by the bolt, and accurate data are provided for the reasonable design of the bolt strength, thereby guaranteeing the safety and reliability of the use of the bolt, the measurement operation is simple and convenient, the measurement is accurate and reliable, and the mechanism used for detecting bolt stress is suitable for detecting the tensile strength of various bolts.
Description
Technical field
the present invention relates to mechanical detection means, being specifically related to a kind of mechanism for detecting bolt stress.
Background technology
during current test bolt tensile strength, general employing fishbolt two ends, directly test with two-way tension machine, due to clamping plate serious wear, clamp insecure, and affect the stressed of bolt and measure, measuring accuracy is not high.
Summary of the invention
technical matters to be solved by this invention overcomes above-mentioned the deficiencies in the prior art, provides one to utilize fixture auxiliary detection bolt stress, and structure is simple, a kind of mechanism for detecting bolt stress that measuring accuracy is high.
the present invention solves the problems of the technologies described above taked technical scheme: a kind of mechanism for detecting bolt stress, be provided with top connection clamping plate, lower sub clamping plate, bolt, upper fixed block, lower fixed block, is characterized in that: bolt upper end loads upper fixed block, lower end screws in lower fixed block, and upper fixed block and lower fixed block are respectively charged in top connection clamping plate and lower sub clamping plate.
advantage of the present invention: owing to adopting said apparatus, this device can measure the maximal destruction tensile fracture that bolt can bear, and the appropriate design for bolt strength provides data accurately, thus ensure that the safety and reliability that bolt uses.Its measurement is simple, convenient, and accuracy of measurement is high, is applicable to multiple bolt tension force and detects.
Accompanying drawing explanation
below in conjunction with drawings and the embodiments, the present invention is further detailed explanation.
fig. 1 is structural representation of the present invention.
Embodiment
as shown in Figure 1, the present invention relates to the mechanism for detecting bolt stress, be provided with top connection clamping plate 1, lower sub clamping plate 2, bolt 3, upper fixed block 4, lower fixed block 5, when testing the maximum tensile fracture of bolt, bolt 3 need be put into upper fixed block 4, and then screw in lower fixed block 5, make fixed block 4, lower fixed block 5, bolt 3 is connected, upper fixed block 4 and lower fixed block 5 are respectively charged at top connection clamping plate 1 and lower sub clamping plate 2, make the bar portion of bolt outside exposed, do not affect the stressed of bolt 3 and measure, the pulling force of two-way tension machine just acts directly on bolt shank.
when the present invention uses, upper, lower sub clamping plate are separately fixed on the upper and lower pull head of puller system, bolt is put into upper fixed block, and then screw in lower fixed block, make fixed block, lower fixed block, bolt is connected, upper fixed block and lower fixed block are respectively charged at top connection clamping plate and lower sub clamping plate, make the bar portion of bolt outside exposed, do not affect the stressed of bolt and measure, the pulling force of two-way tension machine just acts directly on bolt shank, at this moment the maximal destruction tensile fracture that bolt can bear just can be measured, appropriate design for bolt strength provides data accurately, thus ensure that the safety and reliability that bolt uses.Its measurement is simple, convenient, and reliable measuring data, be applicable to multiple bolt tension force and detect.
above-mentioned embodiment is not limitation of the present invention; the present invention is also not limited in above-mentioned citing; the change that those skilled in the art make within the scope of technical scheme of the present invention, remodeling, interpolation or replacement, also all belong to protection scope of the present invention.
Claims (2)
