Abstract
The utility model relates to a test tooling, in particular to a fixture for pull-out force tests. The fixture comprises a fixture body, a groove is arranged in the fixture body along the length direction, an opening is arranged at the top of the fixture body and communicated with the groove in the fixture body, so that the groove is in a reversed T shape, a bar-shaped groove is arranged at the bottom of the groove in the fixture body and parallel to the direction of the opening, and a bottom protrusion is fixedly arranged at the center of the bottom of the fixture body. According to the fixture, the pull-out tests for heat exchange tube convection bundle samples after welding can be performed conveniently, data are real and reliable, and error values can be basically avoided.
Description
Technical field
The utility model relates to a kind of test frock, especially a kind of pulling-out force test fixture.
Background technology
Heat-exchanging tube bundle is being welded in the technological process of tube sheet joint, need carrying out the pulling-out force test to the heat-exchanging tube bundle sample after the welding sometimes, be used for welding technology is evaluated.And the anchor clamps that do not have clear and definite pulling-out force test method in the prior art and specifically be used for the pulling-out force test at present.
The utility model content
The purpose of the utility model is to have proposed a kind of pulling-out force test fixture, can carry out the pulling-out force test to the heat-exchanging tube bundle sample after the welding easily through these anchor clamps, and data is true and reliable, do not have error amount basically.
The utility model is that the technical scheme below adopting realizes: a kind of pulling-out force test fixture comprises chuck body, wherein; Along its length direction groove is set in the said chuck body, the top of chuck body is provided with opening, and opening is connected with the interior groove of chuck body; Make described groove be inverted T-shaped; The bottom of chuck body inner groovy is provided with bar-shaped trough, and bar-shaped trough is parallel to the direction of opening, and the center position of chuck body bottom is fixed with bottom protrusion.
The beneficial effect of the utility model is: draw the pulling-out force test fixture to be fixed on the puller system through this; Can simulate heat exchanger tube convection bank pulling-out force test fixture in real work stressed direction; Easily the heat exchanger tube convection bank sample after the welding is carried out the pulling-out force test; And data are true and reliable, do not have error amount basically.
Description of drawings
Fig. 1 is the front view of the utility model;
Fig. 2 is the vertical view of the utility model;
Fig. 3 is the working state schematic representation of the utility model.
Among the figure: 1 pulling-out force test fixture; 2 chuck body; 3 bar-shaped troughs; 4 bottom protrusion; 5 openings; 6 samples.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 to Fig. 3 is the described pulling-out force test fixture of the utility model.These anchor clamps 1 comprise chuck body 2, along its length direction groove are set in the chuck body 2, and the top of chuck body 2 is provided with opening 5; Opening 5 is connected with chuck body 2 interior grooves; Make described groove be inverted T-shaped, the groove of this shape is convenient to place heat exchanger tube convection bank sample, and the top of heat exchanger tube convection bank is passed opening 5 and stretched out chuck body 2 in the sample; Tube sheet in the sample is arranged in the groove, thereby in process of the test, heat exchanger tube convection bank sample is fixed in the chuck body 2.The bottom of chuck body 2 inner groovies is provided with bar-shaped trough 3, and bar-shaped trough 3 is parallel with opening 5, and the part that the heat exchanger tube convection bank is positioned at the tube sheet below can be arranged on bar-shaped trough 3.The center position of chuck body bottom is fixed with bottom protrusion 4.
Utilize these anchor clamps to carry out pulling-out force when test, at first bottom protrusion 4 is placed on afterburning clamping the in the lower end clamp device of puller system; In second step, the tube sheet in the sample 6 is placed in the groove of chuck body 2, and the opening 5 at chuck body top is passed at the top of heat exchanger tube convection bank, and the bottom of heat-exchanging tube bundle is arranged in the bar-shaped trough 3; The 3rd step was placed on the heat exchanger tube on the tube sheet in the clamp device of puller system upper end successively, and the clamp device of puller system upper end is afterburning to be clamped, and sample is upwards lifted, and exchanged heat pipe successively and carried out the pulling-out force test.
