Abstract
The invention relates to a bolt tensile strength detection clamp. The bolt tensile strength detection clamp is provided with an upper joint clamping plate, a lower joint clamping plate, a bolt, an upper fixing block and a lower fixing block, and is characterized in that the upper end of the bolt is arranged in the upper fixing block, the lower end is screwed in the lower fixing block, and the upper fixing block and the lower fixing block are respectively arranged in the upper joint clamping plate and the lower joint clamping plate. The clamp can be used for precisely measuring the maximum rupture failure tension which can be born by the bolt, and accurate data is provided for the reasonable design of the bolt strength so as to guarantee the security and reliability of the bolt, the measurement is simple and convenient to operate, and the measurement is accurate and reliable, and the clamp provided by the invention is suitable for detecting the tensile strength of a plurality of bolts.
Description
Technical field
The present invention relates to a kind of detection anchor clamps, is that a kind of bolt tensile strength detects anchor clamps specifically.
Background technology
We know, when testing bolt tensile strength at present, generally adopt the fishbolt two ends, directly test with two-way puller system, because the clamping plate serious wear, clamp insecurely, influence the stressed of bolt and measurement, and measuring accuracy is not high.
Summary of the invention
Technical matters to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, and a kind of anchor clamps auxiliary detection bolt tensile strength of utilizing is provided, and is simple in structure, and a kind of bolt tensile strength that measuring accuracy is high detects anchor clamps.
The present invention solves the problems of the technologies described above the technical scheme of taking: a kind of bolt tensile strength detects anchor clamps, be provided with the top connection clamping plate, the lower sub clamping plate, bolt, last fixed block, following fixed block is characterized in that: pack into and go up fixed block in the bolt upper end, the lower end screws in fixed block down, and last fixed block and following fixed block are respectively charged in top connection clamping plate and the lower sub clamping plate.
Problems such as the present invention has solved the clamping plate serious wear owing to adopt said apparatus, clamps insecurely, influences the stressed of bolt and measurement, and measurement result is inaccurate.This device can be measured the maximal destruction tensile fracture that bolt can bear, and for the appropriate design of bolt strength provides accurate data, thereby has guaranteed security and the reliability that bolt uses.Its measurement is simple, convenient, and the accuracy of measurement height, is applicable to that multiple bolt tension force detects.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention;
Accompanying drawing 2 is the fixed block synoptic diagram of going up of the present invention;
Accompanying drawing 3 is fixed block synoptic diagram down of the present invention;
Be labeled as among the figure: 1. top connection clamping plate, 2. lower sub clamping plate, 3. bolt is 4. gone up fixed block, 5. descends fixed block.
Embodiment
Below in conjunction with accompanying drawing the present invention is described further:
As Fig. 1, Fig. 2, shown in Figure 3, the present invention relates to a kind of bolt tensile strength and detect anchor clamps, be provided with top connection clamping plate 1, lower sub clamping plate 2, bolt 3, last fixed block 4, following fixed block 5 when the maximum tensile fracture of test bolt, needs bolt 3 is put into fixed block 4, and then fixed block 5 under screwing in, make fixed block 4, following fixed block 5, bolt 3 is connected, and last fixed block 4 and following fixed block 5 are respectively charged at top connection clamping plate 1 and lower sub clamping plate 2, makes that the bar portion of bolt is exposed outside, do not influence the stressed of bolt 3 and measurement, the pulling force of two-way puller system just acts directly on bolt shank.
When the present invention uses, last, the lower sub clamping plate are separately fixed at puller system up and down on the pull head, bolt is put into fixed block, and then fixed block under screwing in, make fixed block, following fixed block, bolt is connected, last fixed block and following fixed block are respectively charged at top connection clamping plate and lower sub clamping plate, make that the bar portion of bolt is exposed outside, do not influence the stressed of bolt and measurement, the pulling force of two-way puller system just acts directly on bolt shank, at this moment the maximal destruction tensile fracture that can bear of bolt just can be measured, and for the appropriate design of bolt strength provides accurate data, thereby has guaranteed security and reliability that bolt uses.Its measurement is simple, convenient, and reliable measuring data, is applicable to that multiple bolt tension force detects.
