Abstract
The utility model discloses a tension test device of bolts and screws with minor diameters. The tension test device comprises an upper tension rod, a tension joint, a tension ring, a thread bushing and a lower tension rod, wherein the tension joint is in threaded connection with the upper tension rod; the lower end of the tension joint is provided with a notch, in which the head of a sample can be inserted from one side and hung; the tension ring is placed in the thread bushing; the thread bushing is in threaded connection with the lower tension rod; and the tension ring is provided with a threaded hole that can be connected with a screw rod of the sample. The tension test device can conduct tension test on screws with multiple tensile strength conveniently and accurately as shown by the result, and can be used on most hydraulic universal testing machines and electronic type universal testing machines to conveniently adjust the space of an auxiliary appliance.
Description
Technical field
The utility model relates to a kind of tensile test apparatus, the tensile test apparatus of particularly a kind of minor diameter bolt and screw.
Background technology
Bolt screw is mainly used in the various device devices such as machine machinery, highway and railroad bridge, industry and covil construction, pylon as thread connector.Bolt screw mainly plays the fastening effect of connection in various mechanism arrangement, mainly bear axial force, and can bear shearing and extruding that certain radial force produces.The tensile test of bolt screw axially produces quiet pulling force until sample fracture by test unit to sample, also can be by calculating the tensile strength of sample with the maximum test force of measuring the bolt screw sample.The bolt screw tension test of being done on the former universal hydraulic testing machine attaches mostly to be does the above size of M5, lacks the clamping difficulty of bringing for M5 and littler bolt screw because of length, does not generally dispose to attach it is tested.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of minor diameter bolt that can carry out tension test to M5 and littler bolt and screw and the tensile test apparatus of screw are provided.
In order to solve the problems of the technologies described above, the utility model comprises upper pulling force bar, pulling force joint, pulling force ring, thread bush and lower pulling force bar, the pulling force joint is threaded with the upper pulling force bar, the lower end of relay joint be provided with the head end of sample can be from a side be inserted and is hung wherein notch, the pulling force ring is in the thread bush, thread bush is threaded with the lower pulling force bar, and the threaded hole that can be connected with the screw rod of sample is arranged on the pulling force ring.
Be connected with testing machine for convenience, the lower end of the upper end of described upper pulling force bar and lower pulling force bar is cylindrical.
The pulling force ring rotates in thread bush for convenience, and described pulling force ring is an annulus.
The beneficial effects of the utility model are: the utility model can carry out tension test to other screw of multiple tensile strength grade, and the result shows that this device can make things convenient for, test accurately.The utility model can use on most universal hydraulic testing machine and electronic type universal testing machine, adjusts the space that attaches easily.Also can be according to standard GB/T3098.1-2000 " securing member mechanical property bolt, screw and double-screw bolt "
[1]Requirement carry out the assurance load test of bolt screw.By changing the size of pulling force joint, pulling force ring, thread bush, can carry out tension test to the bolt screw of M3.5, M4, M5 equidimension.
