Abstract
Description
Technical Field
[0001] This utility model belongs to the field of titanium rod processing technology, and in particular relates to a titanium rod straightness detection device. Background Technology
[0002] Titanium rod straightness testing refers to assessing the geometric accuracy of a titanium alloy rod by measuring the deviation of its central axis from an ideal straight line. Straightness is a crucial indicator of titanium rod quality, especially in aerospace and medical device fields where high-precision titanium rods must meet stringent straightness tolerances. Traditional testing methods include contact and non-contact measurements, but both are susceptible to environmental temperature fluctuations, leading to distorted results.
[0003] In winter or low-temperature environments, titanium alloys, due to their high coefficient of thermal expansion, will undergo contraction and deformation. Furthermore, the metal structure of the testing equipment may introduce errors due to temperature changes, causing the measured values to deviate from the true straightness. Traditional testing devices lack constant temperature control, and the temperature gradient between the surface and interior of the titanium rod may induce micro-bending, especially noticeable in long rods. Therefore, we provide a titanium rod straightness testing device to address the aforementioned problems. Utility Model Content

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] Example 1
[0026] Please see Figures 1-5This utility model relates to a titanium rod straightness testing device, comprising a testing chamber 1, a support plate 2 inside the testing chamber 1, a rotating wheel 3 between two support plates 2, a laser scanner 4 on the top of the support plate 2, and a temperature control assembly on one side of the testing chamber 1. The temperature control assembly includes a temperature control chamber 5 fixedly connected to one side of the testing chamber 1, a partition pad 6 placed inside the temperature control chamber 5, a chamber cover 7 hinged to the top of the temperature control chamber 5, a first temperature control tube 8 fixedly connected to the bottom of the chamber cover 7, and a first nozzle 9 connected to the bottom of the first temperature control tube 8. Through the setting of the temperature control assembly, the titanium rod is preheated to the standard testing temperature through the temperature control chamber 5, the first temperature control tube 8, and the first nozzle 9, eliminating the shrinkage caused by the low temperature environment. The test chamber 1 is modified to include a heating component on one side. The heating component includes a heating box 10 fixedly connected to one side of the test chamber 1, a fan 11 fixedly connected inside the heating box 10, a heating wire 12 fixedly connected inside the heating box 10, a test frame 13 set on the top of the test chamber 1, a second constant temperature tube 14 fixedly connected to one side of the test frame 13, and a second nozzle 15 connected to the surface of the second constant temperature tube 14. Through the heating component, hot air is delivered into the test chamber 1 via the fan 11, the heating wire 12, and the nozzle of the second constant temperature tube 14 to quickly compensate for temperature fluctuations. The circulation pipe 22 recovers the waste heat of the test chamber 1 and the constant temperature box 5 to the heating box 10, and reheats it by the heating wire 12 for reuse, thereby reducing energy consumption.
[0027] Example 2
[0028] Please see Figures 1-5Based on Example 1, both the testing chamber 1 and the constant temperature chamber 5 are equipped with temperature sensors. A positioning groove adapted to the titanium rod is provided on one side of the partition pad 6. The temperature sensor is existing technology and will not be described in detail here; those skilled in the art will clearly understand its working principle. The temperature sensor is used to detect the temperature inside the testing chamber 1 and the constant temperature chamber 5. The positioning groove prevents the titanium rod from shifting when it is placed. A fixing frame 16 is fixedly connected to the top of the testing chamber 1, and a fixing bracket 16 is fixedly connected to the top of the fixing frame 16. Hydraulic cylinder 17 extends its output end to the bottom of fixed frame 16 and is fixedly connected to detection frame 13. Through the arrangement of fixed frame 16 and hydraulic cylinder 17, the detection frame 13 is pushed up and down to place or remove titanium rods before and after detection. A sliding groove is provided at the top of detection frame 13, and a double-lip sealing strip 18 is fixedly connected inside the sliding groove. Through the arrangement of the sliding groove and double-lip sealing strip 18, the double-lip sealing strip 18 can quickly close after the laser scanner 4 moves, preventing heat loss. A moving mechanism is fixedly connected to the top of detection frame 13. The moving mechanism includes a moving box 19 fixedly connected to the top of the detection frame 13, a drive motor fixedly connected inside the moving box 19, a screw fixedly connected to the output end of the drive motor, a threaded sleeve threaded to the surface of the screw, and a laser scanner 4 fixedly connected to the top and bottom of the threaded sleeve. The moving mechanism is used to move the laser scanner 4. Two conveying pipes 20 are connected to the air outlet of the fan 11. The ends of the two conveying pipes 20 furthest from the fan 11 are respectively connected to the first thermostatic pipe 8 and the second thermostatic pipe 14. The heated air is delivered to the first thermostatic tube 8 and the second thermostatic tube 14 via two delivery pipes 20. A dustproof net 21 is placed inside the heating chamber 10. An air inlet slot is provided on one side of the heating chamber 10. A circulation pipe 22 is connected to the bottom of the thermostatic box 5 and one side of the detection frame 13. The other end of the circulation pipe 22 is connected to the heating chamber 10. The dustproof net 21 prevents external dust from entering the heating chamber 10. The circulation pipe 22 circulates the used hot air back into the heating chamber 10 for reuse, thus reducing energy consumption.
[0029] The working principle of this utility model is as follows: The titanium rod to be tested is first placed on the separator pad 6 inside the constant temperature chamber 5, and its position is fixed by the positioning groove. After placing the separator pad 6 and the titanium rod in the constant temperature chamber 5 and closing the chamber cover 7, the heating wire 12 is started. The fan 11 delivers the dust-removed and heated air after the heating wire 12 to the first constant temperature tube 8 and the second constant temperature tube 14. The air is sprayed into the constant temperature chamber 5 through the first nozzle 9 and into the detection frame 13 through the second nozzle 15, so that the titanium rod is rapidly heated to the preset standard temperature.
[0030] When straightness testing of the titanium rod is required, the cover 7 is opened, and the titanium rod is placed on the support plate 2. The hydraulic cylinder 17 drives the detection frame 13 downward to contact the detection box 1. At this time, the laser scanner 4 is used to test the titanium rod. During the process, the titanium rod can be rotated by the rotating wheel 3 to adjust the detection direction. During the test, hot air is circulated to the heating box 10 through the circulation pipe 22. The temperature sensors in the detection box 1 and the constant temperature box 5 monitor the temperature in real time and are linked with the data of the constant temperature box 5. The temperature sensors transmit the real-time data to the external controller. The external controller dynamically adjusts the power of the heating wire 12 and the wind speed of the fan 11 through the PID control algorithm to ensure that the temperature of the detection area is stable within ±0.5℃, ensuring that the titanium rod is heated evenly and avoiding cold shrinkage deformation or local thermal stress.
[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
