Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing technology, and in particular to a spindle torsion failure testing device. Background Technology
[0002] Destruction testing fixtures are engineering tools used to simulate the extreme mechanical stresses that a product might encounter in real-world use, in order to assess its resistance to failure. These tests induce failure by applying controlled forces (such as tension, compression, shear, torsion, or impact), thereby quantifying the product's ultimate performance and analyzing failure modes.
[0003] Existing testing fixtures cannot be used to test the spindle, and the test data is not presented intuitively. Utility Model Content
[0004] To address the aforementioned technical problems, a spindle torsion failure testing device is provided.
[0005] To achieve the above objectives, in a preferred embodiment of the present invention, the present invention includes a test spindle, the two ends of which are respectively connected to a rotary reducer and a static torque sensor by bolts. The static torque sensor is mounted on a sensor mounting base, and the input shaft of the rotary reducer transmits torque through a torque wrench.
[0006] In a preferred embodiment, the present invention may be further configured such that a plurality of equidistant angle sensors are placed on the top of the test spindle.
[0007] In a preferred embodiment, the present invention may be further configured such that the sensor mounting base and the rotary reducer are fixed to the test bench by bolts.
[0008] In a preferred embodiment, the present invention may be further configured such that the surface of the test bench is provided with crisscrossing grooves, the cross-section of which is T-shaped.
[0009] Beneficial effects: The spindle torsion failure testing device of this utility model has a compact structure, enabling rapid assembly and disassembly, and convenient operation; it adopts torque sensor and angle sensor for collaborative detection, which can simultaneously acquire torque data and torsion angle at different positions of the spindle, and combined with a high-precision display controller, the measurement accuracy reaches 0.05%, and the data recording is intuitive and reliable. Attached Figure Description
[0010] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0011] Figure 1 This is a schematic diagram of the overall structure of this utility model.
[0012] In the diagram, 1 is the test bench; 2 is the static torque sensor; 3 is the sensor mounting base; 4 is the test spindle; and 5 is the rotary reducer. Detailed Implementation
[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] like Figure 1 As shown, a spindle torsion failure testing device includes a test spindle 4. The two ends of the test spindle 4 are respectively connected to a rotary reducer 5 and a static torque sensor 2 by bolts. The static torque sensor 2 is mounted on a sensor mounting base 3. The input shaft of the rotary reducer 5 transmits torque through a torque wrench.
[0015] Angle sensors are used to detect the torsional angle of the spindle at different positions, while static torque sensors collect the applied torque data in real time. The torque change curve is simultaneously displayed and recorded via a handheld instrument, enabling full-process monitoring of the failure process. Data analysis can accurately obtain the spindle's torsional stiffness, yield point, and ultimate failure torque.
[0016] Several sets of equidistant angle sensors are placed on the top of the test spindle 4.
[0017] The sensor mounting base 3 and the rotary reducer 5 are fixed to the test bench 1 by bolts.
[0018] The surface of the test bench 1 is provided with crisscrossing grooves, and the cross-section of the grooves is T-shaped.
[0019] It should be noted that in this article, relational terms such as first and second are used only to distinguish one entity from another, and do not necessarily require or imply any such actual relationship or order between these entities.
[0020] The above examples are merely illustrative of this utility model and do not constitute a limitation on the scope of protection of this utility model. All designs that are the same as or similar to this utility model are within the scope of protection of this utility model.
