Description

Technical Field

[0001] This invention relates to the field of high-temperature tensile testing equipment technology, specifically a translational multi-furnace high-temperature furnace switching platform. Background Technology

[0002] In high-temperature tensile testing systems, the heating and holding time of the high-temperature furnace is relatively long, resulting in long standby time of the main testing unit and low equipment utilization.

[0003] Existing switching stations have relatively limited functionality, with most products primarily focused on load-bearing and lacking integrated design. Their operation is relatively cumbersome and heavily reliant on manual operation. While various switching structures, including cantilever and rotary types, can achieve station switching, they generally lack functionality in areas such as automatic furnace opening and closing, temperature measurement and positioning, sample clamping, and preloading, making it difficult to meet comprehensive testing requirements. Automation and intelligence levels are low, with numerous manual intervention steps and a lack of automation expansion capabilities and supporting safety protection mechanisms. Safety protection is inadequate, with some equipment lacking position detection, and operational safety and stability need improvement. Summary of the Invention

[0004] The purpose of this invention is to provide a translational multi-furnace high-temperature furnace switching platform to overcome the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a translational multi-furnace high-temperature furnace switching platform, comprising a profile frame; a device mounting platform disposed on top of the profile frame; a station switching transmission device installed between the device mounting platform and the profile frame; two sets of automated operating mechanisms installed on the top of the device mounting platform; the station switching transmission device driving the device mounting platform to slide; the station switching transmission device comprising a drive mechanism and a lead screw, wherein a bearing seat is installed at the end of the lead screw, and a lead screw seat is adapted to be connected to the outside of the lead screw; a trigger and a photoelectric switch are disposed between the device mounting platform and the profile frame.

A loading chain is provided in the middle of the high-temperature furnace, and a sample is connected to the middle of the loading chain.

[0007] In a translational multi-furnace high-temperature furnace switching platform according to an embodiment of the present invention, the driving mechanism includes a servo motor and a planetary reducer. The driving mechanism drives the lead screw to rotate along the bearing seat and the inside of the lead screw seat. The lead screw seat is connected to the device mounting platform by bolts.

[0010] In a translational multi-furnace high-temperature furnace switching platform according to an embodiment of the present invention, the bottom of the profile frame is equipped with feet; an adjustable screw is provided between the feet and the profile frame.

[0011] In a translational multi-furnace high-temperature furnace switching platform according to an embodiment of the present invention, the automated operation mechanism includes an X-axis moving mechanism, a Y-axis moving mechanism is installed on the top of the X-axis moving mechanism, and an automatic temperature measuring device and an automatic opening and closing device are installed at the end of the Y-axis moving mechanism; the high-temperature furnace is fixed to the middle of the automatic opening and closing device by bolts, and the automatic opening and closing device drives the high-temperature furnace to open and close automatically.

[0012] In a translational multi-furnace high-temperature furnace switching platform according to an embodiment of the present invention, a clamping device and a pre-tightening device are installed at the end of the Y-axis moving mechanism; the clamping end of the clamping device is in contact with the outer side of the loading chain.

[0013] In a translational multi-furnace high-temperature furnace switching platform according to an embodiment of the present invention, the clamping device cooperates with the pre-tightening device to apply a controllable pre-tightening force to the loading chain to ensure the coaxiality of the sample.

[0014] In the above, the controllable preload eliminates assembly gaps, ensures that the sample and the loading chain are coaxial, and reduces test data deviation; the preload protects the thermocouple from being deflected, improving test accuracy and test success rate.

The two sets of automated operating mechanisms can work synchronously at the test station and the preparation station respectively, minimizing the standby time of the main unit, improving equipment utilization, significantly shortening the overall test cycle, and meeting the needs of efficient batch testing in the laboratory.
