Description
Technical field
The utility model belongs to the clamp technology field in the mechanical industry, especially a kind of auxiliary clamp that is used on the tension tester.
Background technology
In the physics laboratory, cupping machine is the instrument and equipment of material and member physical property detection range, the course of work is: (it is big and short to be shaped as the two ends diameter with sample to be checked, the ladder right cylinder that mid diameter is little and long) two ends clamp respectively by the upper jaw on the cupping machine, lower jaw, apply pulling force by tension tester then, show stress and assay simultaneously.
The upper and lower jaw of cupping machine at a distance of length generally about 200mm.According to " electro-hydraulic servo cupping machine vertification regulation ", requirement evenly clamps sample in the overall length of retained part, a standard sample total length needs greater than 300mm so, because retained part is long, sample base specification strengthens, increase material and processing cost, particularly the increase of non-ferrous metal experimental material cost is bigger.
Because sample is excessive, limited many profiled pieces laterally, Z to etc. the test of special sample, the range of application of tension tester also is restricted.
The utility model content
The purpose of this utility model provides a kind of easy for installation, simple in structure, saves a kind of auxiliary clamp that is used on the tension tester of sample materials.
The purpose of this utility model realizes by following technical proposals:
A kind of auxiliary clamp that is used on the tension tester of the present utility model, it is characterized in that being provided with the major axis of screw thread by the end, the adapter sleeve that is threaded of major axis therewith, the gripping sleeve that connects of adapter sleeve therewith, the fixed cover that is rotationally connected of gripping sleeve outside surface is formed therewith, and described gripping sleeve is made up of two semicircle clamping elements.
The outside surface of described two semicircle clamping elements is a conical outer surface, and the upper and lower end of the inside surface of these two semicircle clamping elements is respectively equipped with boss.
The inside surface of described fixed cover is a cone-shaped inner surface, and the conical outer surface of this cone-shaped inner surface and described two semicircle clamping elements is complementary.
The outer surface of upper circumferencial direction of described adapter sleeve is provided with a circle groove, and the boss of described two semicircle clamping element lower ends plugs with a circle groove of the outer surface of upper circumferencial direction that is located at described adapter sleeve.
Described gripping sleeve can be the gripping sleeve of different size, unlike material, to adapt to the starting material sample of different requirements, different size specification.
Using method of the present utility model and step:
1) at first widens upper jaw on the tension tester and the stroke between the lower jaw before the experiment;
2) end of the utility model by major axis is connected with the lower jaw of tension tester, an end of the sample that is used to test is connected with the upper jaw of tension tester;
3) open tension tester stroke button, upper jaw and sample are descended together, sample passes fixed cover in the decline process, when the lower end for the treatment of sample can clamp the position and arrives in the gripping sleeve, stops to descend;
4) the upper end boss of two semicircle clamping elements is stuck in the end of sample in the gripping sleeve, and moving being enclosed within on the outside surface of two semicircle clamping elements of the supreme slow-speed of waiting a moment downwards of fixed cover makes it be fixed into one then, forms complete clamp system;
5) tensile test begins.
The utility model has the advantages that:
1) the utility model is installed after, can shorten the distance between two bits on the tension tester greatly, saved and be used for the used starting material of pulling force sample, especially the value of saving is considerable especially for valuable alloy.
2) can select satisfactory clamping distance arbitrarily according to the specification of sample, also can install and use simultaneously by upper and lower jaw, make things convenient for the sampling and the processing of sample.
3) because sample contacts with gripping sleeve and is the arc surface uniform contact, reduce the specimen fails that causes owing to jaw clamping force inequality, improved the utilization factor of sample.
4) simple in structure, easy for installation, cheap for manufacturing cost, change easily.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is the cut-open view of the utility model Fig. 1.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.
As shown in Figure 1, 2, a kind of auxiliary clamp that is used on the tension tester of the present utility model, it is characterized in that being provided with the major axis 1 of screw thread by the end, the adapter sleeve 2 that is threaded of major axis 1 therewith, the gripping sleeve 3 that connects of adapter sleeve 2 therewith, the fixed cover 4 that is rotationally connected of gripping sleeve 3 outside surfaces is formed therewith, and described gripping sleeve 3 is made up of two semicircle clamping element 3-1.
The outside surface of described two semicircle clamping element 3-1 is a conical outer surface, and the upper and lower end of the inside surface of these two semicircle clamping elements is respectively equipped with boss.
The inside surface of described fixed cover 4 is a cone-shaped inner surface, and the conical outer surface of this cone-shaped inner surface and described two semicircle clamping element 3-1 is complementary.
The outer surface of upper circumferencial direction of described adapter sleeve 2 is provided with a circle groove, and the boss of the lower end of described two semicircle clamping element 3-1 plugs with a circle groove of the outer surface of upper circumferencial direction that is located at described adapter sleeve 2.
Described gripping sleeve 3 can be the gripping sleeve of different size, unlike material, to adapt to the starting material sample of different requirements, different size specification.
The utility model has the advantages that:
1) behind installation the utility model, can greatly shorten the distance between two bits on the tensile testing machine, save for the used raw material of tension sample, especially the value of saving is especially considerable for precious alloy.
2) can select arbitrarily satisfactory clamping distance according to the specification of sample, make things convenient for sampling and the processing of sample.
3) because sample contacts with gripping sleeve and is the arc surface even contact, reduce the specimen fails that causes owing to the jig jaw clamping force inequality, improved the utilization rate of sample.
4) simple in structure, easy for installation, cheap for manufacturing cost, change easily.
