Abstract

The utility model discloses a general-purpose bolt/nut test fixture, which consists of an upper clamp block, a lower clamp block, a test screw bolt (special used for protecting load of a test nut), etc. The shape of the upper clamp block and the lower clamp block is matched with an upper jaw seat and a lower jaw seat of a universal testing machine, and the upper clamp block and the lower clamp block adopt the thread connection test bolt or the test nut. The upper clamp block and the lower clamp block are respectively arranged on the upper jaw seat and the lower jaw seat of the universal testing machine. The upper clamp block and the lower clamp block are directly matched and connected with the upper jaw seat and the lower jaw seat; with no need for changing a wedge-shaped fixture experimental bench, the exchange between the general-purpose tension test and the bolt strength test can be realized. The general-purpose bolt/nut test fixture has the advantages of simple structure, as well as accurate, efficient and convenient use, and the like.

Description

Ordinary bolt/nut test fixture
Technical field
The present invention relates to a kind of technical field of universal testing machine, particularly relate to a kind of universal testing machine bolt/nut test fixture.
Background technology
At present, each test mechanism majority is finished stretching/guarantor year test of bolt/nut on universal testing machine, when double thread securing member (bolt/nut) carries test stretching/guarantor, the frequent replacing of anchor clamps is the problem of being paid close attention to always, and the bolt test fixture mainly adds that by the special-purpose jaw of bolted fixture thread bush is formed up and down at present.Material extending anchor clamps dismounting that need be huge when being bolt tension/guarantor and carrying change bolted fixture special use jaw into down again.Generally, large-tonnage universal testing machine master trip anchor clamps are heavier, and changing anchor clamps needs the collaborative clamping of two people, and it is long to change the anchor clamps time, often changes anchor clamps and easily produces the gap.
China Patent No. ZL 200420012870.2 discloses a kind of special bolt test fixture, it is made up of last anchor clamps, lower clamp, nut clamp etc., last anchor clamps, lower clamp are installed in respectively on the upper and lower chuck of tension tester, nut clamp is installed on the lower clamp, and last anchor clamps are the framed structure of hollow.Weak point is, last anchor clamps, lower clamp unreasonable structure, and the jaw seat cooperates and is unfavorable for quick, convenient installation, especially is not suitable for Wedge gripping testing table on the universal testing machine.
Summary of the invention
The objective of the invention is to the deficiency that exists in the existing clamp-replacing, a kind of bolt/nut test fixture accurate, efficient, easy to use is provided.And need not change Wedge gripping testing table on the universal testing machine.
Technical scheme of the present invention is:
A kind of bolt test fixture comprises fixture block, following fixture block; Last fixture block, following fixture block are installed in respectively on universal testing machine upper jaw, the lower jaw; It is characterized in that: going up fixture block is bolt shape, and an end has the block adaptive with upper jaw, and the other end has and the adaptive screw of test bolt; Following fixture block is for adapting to lower jaw and test bolting pad round.
A kind of nut test fixture comprises fixture block, following fixture block; Last fixture block, following fixture block are installed in respectively on universal testing machine upper jaw, the lower jaw; It is characterized in that: test bolt in addition; Last fixture block is to adapt to upper jaw and the movable washer-shaped that is inserted in the test bolt; Following fixture block is the washer-shaped that adapts to lower jaw and test bolt; Test bolt one end has and lower jaw and the adaptive block of fixture block down, and the other end has and the adaptive screw thread of test nut.
Good effect of the present invention: since it by last fixture block, down fixture block, test screw rod (nut protect carry special-purpose) wait and form, will go up fixture block, following fixture block is installed in respectively on the upper and lower jaw seat of universal testing machine.Last fixture block, following fixture block directly cooperate with bit, need not change universal testing machine Wedge gripping testing table, just can realize the exchange of general tensile test and bolt strength test.Have characteristics such as simple in structure, accurate, efficient, easy to use.
Below with reference to drawings and Examples, the present invention is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is a bolt tension force test fixture organigram.
Fig. 2 protects for nut and carries the test fixture organigram.
Among the figure: 1. upper jaw, 2. go up fixture block, 3. the test bolt, 4. play fixture block, 5. lower jaw, 6. the test nut.
Embodiment
Embodiment 1, and Fig. 1 is a bolt tension force test fixture organigram.As shown in Figure 1: the bolt tension force test fixture comprises fixture block 2, following fixture block 4.To go up fixture block 2, play fixture block 4 to be installed in respectively on universal testing machine upper jaw 1, the lower jaw 5.It is characterized by: go up fixture block 2 and be bolt shape, an end has the block adaptive with upper jaw 1, and the other end has the screw adaptive with test bolt 3; Following fixture block 4 is for adapting to lower jaw 5 and test bolt 3 washer-shapeds.
Bolt when test, will test bolt 3 and be mounted to up and down on the fixture block, will go up fixture block 2 again, fixture block 4 is installed in respectively on upper jaw 1, the lower jaw 5 down, adjust distance between the test fixture according to the length of testing bolt 3.
Embodiment 2, and Fig. 2 protects for nut and carries the test fixture organigram.As shown in Figure 2: the nut test fixture comprises fixture block 2, following fixture block 4.To go up fixture block 2, play fixture block 4 to be installed in respectively on universal testing machine upper jaw 1, the lower jaw 5.It is characterized by: test bolt 3 in addition; Last fixture block 2 is for adapting to upper jaw 1 and the movable washer-shaped that is inserted in test bolt 3; Following fixture block 4 is for adapting to the washer-shaped of lower jaw 5 and test bolt 3; Test bolt 3 one ends have and lower jaw 5 and the adaptive block of fixture block 4 down, and the other end has the screw thread adaptive with test nut 6.
Nut when test, will test nut 6 and be mounted on upper and lower fixture block and the test bolt, will go up fixture block 2 again, fixture block 4 is installed in respectively on upper jaw 1, the lower jaw 5 down, adjust distance between the test fixture by the length of testing bolt 3.
Above-mentioned two embodiment explanation need not be changed the Wedge gripping testing table, just can realize the conversion of general tensile test and bolt strength test.
Before process of the test, also extensometer can be installed, carry out in the drawing process at bolt, just can carry out the mensuration of yield strength and extensibility.This test fixture also can be lacked the sample (tensile test of L 〉=30mm).
