Description

Technical Field

[0001] This utility model relates to the field of aerospace thermal vacuum testing technology, and in particular to a tooling for arranging points for thermal vacuum testing. Background Technology

[0002] A crucial aspect of environmental testing for aerospace products is the thermal vacuum test. During this test, the product is placed in a vacuum chamber and subjected to rigorous thermal cycling under vacuum conditions.

[0003] During the test, temperature monitoring is required at multiple points on the product. The temperature signal from each monitoring point is transmitted outward through the thermocouple wires attached to that point. Due to product and test requirements, dozens of thermocouple sets are often attached to the product in a single test. Each thermocouple set is led out by two wires, one positive and one negative. Based on past experience, each thermocouple set is coiled on a spool for easy attachment to the temperature measuring points during the test preparation stage. After the thermocouple ends are attached, the ends of the thermocouple wires wound on the spool are extended outward. Once dozens of temperature measuring points have been attached, these extended thermocouple ends need to be grouped and soldered onto sealing connectors as required, and then led out of the container through these connectors.

[0004] For example, a placement fixture for thermal vacuum testing, disclosed in CN207741869U, uses a spool holder to store thermocouple wires and a wire support assembly to straighten and fix the thermocouple wires, making the originally messy thermocouple wires neat. However, existing placement fixtures for thermal vacuum testing have multiple sets of spools, making it cumbersome and complicated to manually wind and arrange the thermocouple wires, increasing the cumbersomeness of operation and reducing the efficiency of winding and arranging the thermocouple wires.

[0005] Therefore, it is necessary to provide a spotting fixture for thermal vacuum testing to solve the above-mentioned technical problems. Utility Model Content

[0034] A bobbin seat 5 is disposed on the outer surface of the rotating device 4. The bobbin seat 5 includes a bobbin 51, a sleeve hole 52 and a groove 53. The bobbin 51 is sleeved on the outer surface of the rotating column 41. The sleeve hole 52 is opened in the middle of the top of the bobbin 51, and the groove 53 is opened on one side inside the sleeve hole 52.

[0035] A wire support device 3 is fixedly installed on one side of the front of the trolley 1, and movable wheels 6 are provided around the bottom of the trolley 1. A push rod 7 is fixedly installed on the top of the rear side of the trolley 1.

[0036] The first driving component 24 adopts a servo motor structure, and the top end of the output shaft of the first driving component 24 extends to the top outer surface of the mounting plate 21 and connects to the rotating column 41.

[0037] The elastic element 45 adopts a spring structure, and one end of the elastic element 45 is fixedly connected to the surface of the compression block 46.

[0038] The card block 48 is in the shape of an isosceles triangular block, with an inclined surface set on the top surface of the card block 48, and the moving block 47 and the card slot 53 are adapted to each other.

[0041] The working principle of the sampling fixture for thermal vacuum testing provided by this utility model is as follows:

[0042] During operation, the spool 51 is first fitted onto the outer surface of the rotating column 41 through the fitting hole 52. As the spool 51 presses down on the top inclined surface of the locking block 48, the locking block 48 is pressed into the interior of the receiving groove 42. The locking block 48 drives the pressing block 46 to slide along the slide rod 44. The pressing block 46 presses the elastic element 45. When the slot 53 and the receiving groove 42 are connected, the restoring elastic force of the elastic element 45 pushes the pressing block 46. The pressing block 46 is embedded into the interior of the slot 53, thus restricting the spool 51.

[0043] The rotation of the first driving component 24 drives the rotating column 41 and the spool 51 to rotate, so that the spool 51 automatically winds and lays the thermocouple wire.

[0044] When it is necessary to disassemble the spool seat 5, the user pushes the squeezing block 46 to slide and squeeze the elastic element 45 on the surface of the slide bar 44. The squeezing block 46 drives the locking block 48 to move and be stored in the storage groove 42. The locking block 48 disengages from the groove 53, making it convenient for the user to remove the spool 51 from the top of the rotating column 41.

[0045] Compared with related technologies, the point-layout fixture for thermal vacuum testing provided by this utility model has the following beneficial effects:

[0046] This utility model provides a fixture for thermal vacuum testing. The elastic force of the elastic element 45 pushes the locking block 48 into the surface of the inlet spool 5, so that the spool 5 and the rotating column 41 are fixed together. When the first driving element 24 controls the rotating column 41 to rotate, it drives the spool 5 to rotate, thereby winding and laying the thermocouple wire. This device has a simple structure and strong practicality. It realizes automatic winding and laying of thermocouple wire, reduces operation steps, and improves the working efficiency of winding and laying thermocouple wire.

[0051] The working principle of the sampling fixture for thermal vacuum testing provided by this utility model is as follows:

[0052] During operation, the output shaft of the second drive component 88 first rotates, driving the drive gear 85 and the drive traction roller 82 to rotate. At this time, the drive gear 85 rotates and meshes with the driven gear 86 to rotate. The driven gear 86 drives the driven traction roller 83 to rotate, causing the drive traction roller 82 and the driven traction roller 83 to rotate and pull the thermocouple wire to move. At the same time, the drive traction roller 82 and the driven traction roller 83 straighten the bent section of the thermocouple wire.
