Abstract
The utility model is a kind of lag bolt stretching accessory, comprise frock and lower frock, upper frock comprises the n shape seat that top is provided with joint pin, is provided with the guide holder of sheathed Compress Spring in n shape seat, guide holder is set with the L shape seat of two docking, two L shape seat ends are provided with semicircle gap; Lower frock comprises the truncated cone-shaped seat that bottom is provided with lower joint pin, and the end face of truncated cone-shaped seat offers threaded hole.The utility model lag bolt stretching accessory has the advantages such as extended capability is strong, the comprehensive method of investment is little, flexible and convenient operation, the expanded range that the utility model lag bolt stretching accessory makes the bolt tension experiment of tension tester be suitable for.
Description
Technical field
The utility model relates to bolt tensile strength detection technique field, and particularly a kind of is the device used in the lag bolt tensile strength process of 15mm to 60mm, specifically a kind of lag bolt stretching accessory at check length.
Background technology
Standard component is the stressed part of indispensable important connection in automobile making and other assembling manufacturing industry, especially the status occupied in assembling process of bolt, and the performance of its bearing capacity will be directly connected to the safe mass of the assembled products such as automobile.So the mechanical propertys such as the bolt tensile strength used in test set-up process are then even more important, but often because the own limitations of experimental facilities cannot the testing the bolt of all models of just true all standing, such as: length is the lag bolt of 15mm to 60mm, because the reason of equipment cannot carry out tensile strength test to it, can only indirectly infer its tensile strength by forms such as tested for hardness, and this method of testing can not reflect its just genuine tensile strength mechanical property completely.
Summary of the invention
The purpose of this utility model is cannot the problem of tested for tensile strength in order to solve the bolt of length in 15mm to 60mm scope, and provides a kind of lag bolt stretching accessory.The utility model can meet request for utilization completely, and extended capability is strong, and the comprehensive method of investment is little, flexible and convenient operation.
The utility model is achieved by the following technical solution:
A kind of lag bolt stretching accessory, comprises frock and lower frock; Described upper frock comprises n shape seat, and the top center place of n shape seat is vertically fixed with joint pin, is evenly fixed with four guideposts between the two side in n shape seat, point two, top and two, bottom; On four guideposts, slip cap is equipped with two L shape seats, and two L shape seats are put relatively with its leveling board end, and the centre position of the leveling board end of two L shape seats offers the identical semicircle gap of size; Part on four guideposts between n shape seat left side wall and left side L shape seat and the part between n shape seat right side wall and right side L shape seat are all respectively installed with Compress Spring, and two of left and right sides L shape seats are butted into U-shape under the effect of Compress Spring elastic force, and the semicircle gap on two L shape seats is butted into cylindrical hole; Described lower frock comprises truncated cone-shaped seat, and the place of bottom center of truncated cone-shaped seat is vertically fixed with lower joint pin, and the end face center of truncated cone-shaped seat offers threaded hole along its axis.
During use, the upper joint pin of upper frock is connected with bare terminal end on puller system, lower work is held joint pin be connected with bare terminal end under puller system, then bolt is screwed in the threaded hole of lower frock truncated cone-shaped seat, and only need the minimum screw rod leaving 7mm, again by two of upper frock L shape seats separately, between semicircle gap bolt being placed in two L shape seats, unclamp two L shape seats, two L shape seats dock closed under the effect of Compress Spring elastic force, now the upper part holding of bolt screw rod is between the semicircle gap of two L shape seats, the nut holding of bolt is on the leveling board of two L shape seats, reach simple and flexible installation effect, without the need to leaving gap in the middle of bolt tension force accessory.
Further, the end opening end of the semicircle gap of L shape seat leveling board end is the expansion design of arc transition.After the leveling board docking of two L shape seats, the semicircle gap on two L shape seats is butted into cylindrical hole, and the aperture, bottom of this cylindrical hole is the expansion mouth of arc transition, and this expansion mouth is used for making a concession to the truncated cone-shaped seat top of lower frock.
The utility model lag bolt stretching accessory has the advantages such as extended capability is strong, the comprehensive method of investment is little, flexible and convenient operation, the expanded range that the utility model lag bolt stretching accessory makes the bolt tension experiment of tension tester be suitable for.
