Description
Technical field
The utility model relates to a kind of nail-holding power pick-up unit, is mainly applicable to the detection to nail-holding power.
Background technology
In commercial production, the use amount of timber is very large.General timber, the material fluctuation ratio of every batch is larger, and we mainly distinguish with the quality of nail-holding ability, and nail-holding power refers to: nail enters after sheet material, and easily whether easily whether nail staple hole, loose or dislocation.The sheet material bed knife that nail-holding ability is good is strong, and nail is difficult for loose or dislocation, and nail hole can be recycled; Hardness, intensity and density are all larger, and the poor plank of nail-holding ability is contrary.Therefore need before use Mei Pijin factory nail-holding power quality to monitor.Detecting in the past the operation of nail-holding ability is: use below a multifunctional stretching equipment hook is installed, a wooden unit chuck, carries out nail-holding ability detection to the wooden unit of fixing iron nail of the fixed measure processing.The detection of a nail-holding power, needs first wooden unit to be fixed the processing of size, fixes nail in the fixed position of wooden unit, finally detects accordingly with checkout equipment.Detect existence with this device high to timber size requirement, measurement range is little; The shortcomings such as device stability is not high, causes detecting the shortcoming that data fluctuations is large, while adopting existing apparatus to carry out nail-holding ability detection, need to readjust chuck position when there is deviation iron nail position on wooden unit simultaneously, and existence requires high to sample preparation, detection efficiency is low.
Utility model content
The technical matters that the utility model solves is that the above-mentioned defect for overcoming prior art provides a kind of energy enlarge measurement range, and stable detection data, reduce sample preparation requirement, improve the nail-holding power pick-up unit of detection efficiency.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of nail-holding power pick-up unit, comprise compression testing machine, it is characterized in that being also provided with iron nail stretching framework, base for supporting, iron nail stretching framework is fixedly connected with the pressing plate of compression testing machine, base for supporting is placed on compression test machine base, iron nail stretching frame sets up and is equipped with the stressed groove of iron nail, and the stressed groove of described iron nail is arranged at the bottom of iron nail stretching framework.
Base for supporting described in the utility model is provided with fluting, and described base for supporting fluting coordinates with the framework post of iron nail stretching framework.
The stressed groove of iron nail described in the utility model is the head of a nail diameter that U-shaped groove and width are less than iron nail.
Iron nail stretching framework described in the utility model is fixedly connected with the pressing plate of compression testing machine with latch by round steel.
The utlity model has simple for structure, enlarge measurement range, stable detection data, reduce sample preparation requirement, improve the features such as detection efficiency.

Fig. 2 is the structural representation of the utility model embodiment.
View when Fig. 3 is the utility model embodiment iron nail malcompression.
View when Fig. 4 is the utility model embodiment iron nail compression.
Fig. 5 is that enlarged diagram is looked up in the part of the iron nail of the utility model embodiment shown in Fig. 2 stretching framework.
Embodiment
Referring to Fig. 1～Fig. 5, the utility model embodiment nail-holding power pick-up unit utilizes existing multi-functional resistance to compression (drawing) testing machine 1, design a set of pick-up unit, mainly comprise: an iron nail stretching framework 2, iron nail stretching framework 2 upper ends are connected and fixed with the pressing plate 7 of compression testing machine 1 by round steel 3 and latch 4; A base for supporting 5, when this device uses, base for supporting 5 is placed on position suitable on compression test machine base.When use, fix iron nail stretching framework 2 in 7 times connections of compression testing machine 1 pressing plate, for the iron nail 9 on fixing wooden unit 8, below place base for supporting 5, be used for supporting detected wooden unit 8, iron nail stretching framework 2 bottoms (centre is hollow) be provided with the stressed groove 6(of iron nail preferably this groove be U-shaped opening), stressed groove 6 width of iron nail (left and right distance) are less than the head of a nail 91 diameters (the nethermost maximum gauge of the head of a nail 91 in Fig. 3) of iron nail 9, and iron nail 9 can be blocked by the stressed groove 6 of iron nail.Then directly use compression testing machine 1 can carry out nail-holding ability detection.
The present embodiment base for supporting 5 is provided with fluting 51, and framework post 21 width of described iron nail stretching framework 2 are less than described fluting 51(framework post 21 and coordinate with fluting 51), when therefore iron nail stretching framework 2 declines, can not withstand base for supporting 5.The stressed groove of described iron nail is located at the bottom of iron nail stretching framework 2.
General principles or the operating process of the present embodiment work are as follows:
In iron nail stretching framework 2, packing nail into has the wooden unit 8 of iron nail 9, iron nail 9 is stuck in to the stressed groove 6(of iron nail for block the head of a nail 91 of iron nail 9 in detection) in, and wooden unit 8 is placed on base for supporting 5, start multi-functional compression testing machine 1, pressing plate 7 on this compression testing machine 1 can stretch iron nail framework 2 toward pressing down, its position of support that now wooden unit 8 is subject to base for supporting 5 keeps motionless, the stressed groove 6 of iron nail can block the head of a nail of iron nail 9 and to one downward pressure, thereby records iron nail 9 and extract from wooden unit 8 power of generation.The power now recording is exactly the value of timber 8 nail-holding abilitys.
The utility model, compared with background technology, has following advantage: 1, expand sensing range, and less for wooden unit size restrictions, can use existing wooden unit in production to make, without special making.2, the present embodiment is to iron nail 9, wooden unit 8 good fixing effect, and testing result data fluctuations is little.3, when the present embodiment detects, reduce for iron nail 9 status requirements, without adjust at every turn, improved detection efficiency.
The equivalent transformation of every technical solutions of the utility model and technical characterictic or combination, all should think and fall into protection domain of the present utility model.
