Description

Technical Field

[0001] The present application relates to the field of detection tooling, and more particularly to a heat resistance detection tooling for parts. Background Art

[0002] In the prior art, when an operator uses a laser to weld two parts into a part assembly, a large amount of heat is generated during laser welding. After the parts absorb the heat, they expand rapidly, and cracks are likely to appear in the expanded areas of the parts. However, the operator can only check whether there are cracks in the part assembly after welding is completed. Once any one or both of the two parts have cracks, the entire part assembly must be scrapped, resulting in waste of parts and increasing the manufacturing cost of the part assembly.

Moreover, by fixedly connecting the connecting portion to the installation wall surface, it can be avoided that when the housing is subjected to an external force, the housing is pushed down by the external force, resulting in separation of the part to be tested and the housing, thereby further improving the working reliability of the heat resistance detection tooling for parts.

[0035] The following further elaborates on the present application Figure 1 - Figure 2 with reference to the accompanying drawings.

[0036] An embodiment of the present application discloses a part heat resistance detection tooling 100.

[0037] Referring to Figure 1 and Figure 2 , the part heat resistance detection tooling 100 according to an embodiment of the present application includes: a housing 1, a heating element 2, a power source, and a crack detection element. The heating element 2 is disposed inside the housing 1. The housing 1 is adapted to extend into the part under test so that the heating element 2 heats the part under test, and the heating element 2 is spaced apart from the part under test. The power source is electrically connected to the heating element 2, and the crack detection element is used to detect surface cracks of the part under test.

[0038] Specifically, in the height direction of the housing 1, the upper end portion of the housing 1 is adapted to extend into the part to be tested, and the upper end portion of the housing 1 is used to support the part to be tested. That is to say, when using the part heat resistance detection tooling 100 to detect the part to be tested, the operator places the part on the upper end portion of the housing 1, and the height direction of the housing 1 can refer to Figure 1 the up and down direction in

[0039] When the upper end portion of the housing 1 extends into the part to be tested, the operator starts the power supply to enable the heating element 2 to start working. The heat generated by the heating element 2 is conducted to the part to be tested through the housing 1, so that the part to be tested is uniformly heated, thereby avoiding excessive temperature in a local area of the part to be tested and avoiding cracks in a local area of the part to be tested caused by thermal expansion in a local area of the part to be tested, and further improving the working reliability of the part heat resistance detection work.

[0040] After the part is heated to the preset temperature, the operator turns off the power supply to stop the heating element 2 from working, and the operator takes out the heated part from the housing 1. Then, the operator uses the crack detection piece to detect whether there are cracks on the outer surface of the heated part. When there are no cracks on the outer surface of the heated part, the heated part is a qualified part, and the qualified part can be used for laser welding. When there are cracks on the outer surface of the heated part, the heated part is an unqualified part and is scrapped.

[0041] In some specific embodiments, the heating element 2 can be a heating wire, and the crack detection piece can be a magnifying glass, but the present application is not limited thereto. The heating element 2 can also be a heating rod, etc., and the crack detection piece can also be an ultrasonic detector, etc.

[0042] In some specific embodiments, the preset temperature can be 245°.

[0043] In some specific embodiments, the shape of the upper end portion of the housing 1 can be configured as a cylinder, and the diameter dimension of the upper end portion of the housing 1 is smaller than the diameter dimension of the part to be tested.

[0044] Thus, by arranging the heating element 2 in the housing 1 and the housing 1 extending into the part to be tested, the heat generated by the heating element 2 is conducted to the part to be tested through the housing 1. After the part to be tested is heated, the operator uses the crack detection piece to detect whether there are cracks on the outer surface of the heated part. Compared with the prior art, the part heat resistance detection tooling 100 can detect whether cracks will occur in the part after thermal expansion before laser welding of the part, thereby reducing waste of parts and further reducing the manufacturing cost of part components.

[0045] Refer to Figure 1 and Figure 2, in some embodiments of the present application, the housing 1 includes a connecting portion 11 and a supporting portion 12. The supporting portion 12 is adapted to extend into the part to be tested. The connecting portion 11 is fixedly connected to the mounting wall surface. Specifically, along the height direction of the part heat resistance testing tooling 100, the supporting portion 12 is located above the connecting portion 11. The supporting portion 12 is adapted to extend into the part to be tested, and after the supporting portion 12 extends into the part to be tested, the supporting portion 12 is used to support the part to be tested, so as to avoid the part to be tested detaching from the housing 1, and avoid the heat generated by the heating element 2 from not being conducted to the part to be tested, thereby improving the working reliability of the part heat resistance testing tooling 100.

[0046] Moreover, by fixedly connecting the connecting portion 11 to the mounting wall surface, it can be avoided that when the housing 1 is subjected to an external force, the housing 1 is pushed down by the external force, resulting in the separation of the part to be tested and the housing 1, thereby further improving the working reliability of the part heat resistance testing tooling 100.

[0047] In some specific embodiments, the mounting wall surface can be the tabletop of a workbench, but the present application is not limited thereto, and the mounting wall surface can also be a desktop or the like.

[0048] In some specific embodiments, the shape of the connecting portion 11 and the shape of the supporting portion 12 can both be configured as circular.

[0049] In some specific embodiments, the connecting portion 11 can be adhered to the mounting wall surface by glue, but the present application is not limited thereto, and the connecting portion 11 can also be fixedly connected to the mounting wall surface by threaded fasteners.

[0050] Refer to Figure 1 and Figure 2 , in some embodiments of the present application, a mounting hole 111 is provided on the end wall of the connecting portion 11 away from the supporting portion 12. The fastener passes through the mounting wall surface and extends into the mounting hole 111 to fixedly connect the connecting portion 11 to the mounting wall surface. In some specific embodiments, the fastener can be a screw, but the present application is not limited thereto, and the fastener can also be a pin.

[0051] Specifically, along the height direction of the part heat resistance testing tooling 100, a mounting hole 111 is provided on the lower end wall of the connecting portion 11, and an avoidance hole opposite to the mounting hole 111 is provided on the mounting wall surface, and the avoidance hole is a through hole for avoiding the fastener.

[0052] By using the fastener to pass through the avoidance hole of the mounting wall surface and extend into the mounting hole 111, the technical effect of fixedly connecting the housing 1 to the mounting wall surface can be achieved, and it can be avoided that the housing 1 tilts, resulting in the part to be tested not being able to be placed at the preset position of the housing 1, and it can be avoided that the part to be tested cannot be evenly heated, thereby improving the working reliability of the part heat resistance testing tooling 100.

[0053] Refer toFigure 1 and Figure 2 In some embodiments of the present application, there are multiple mounting holes 111, and the multiple mounting holes 111 are arranged in sequence along the circumferential direction of the housing 1. Along the height direction of the part heat resistance detection tooling 100, by providing multiple mounting holes 111 on the end wall of the connecting portion 11 away from the supporting portion 12, and a fastener is connected between each mounting hole 111 and the mounting wall surface. Such a setting can improve the connection reliability between the housing 1 and the mounting wall surface, making the connection between the housing 1 and the mounting wall surface more firm.

[0054] Refer to Figure 1 and Figure 2 In some embodiments of the present application, a positioning portion 121 is provided on the end wall of the supporting portion 12 away from the connecting portion 11. The positioning portion 121 is adapted to be in positioning cooperation with the part to be tested. Specifically, along the height direction of the part heat resistance detection tooling 100, the positioning portion 121 is located at the upper end of the supporting portion 12. The part to be tested is provided with a positioning hole opposite to the supporting portion 12. When the supporting portion 12 extends into the part to be tested, the positioning portion 121 extends into the positioning hole to enable the positioning portion 121 to be in positioning cooperation with the part to be tested.

[0055] By the positioning portion 121 being in positioning cooperation with the part to be tested, it is possible to prevent the part to be tested from deviating from the preset placement position, and it is possible to prevent the part to be tested from separating from the supporting portion 12, resulting in the part to be tested not being heated, and further improving the working reliability of the part heat resistance detection tooling 100.

[0056] Refer to Figure 1 and Figure 2 In some embodiments of the present application, a receiving hole 13 is provided at the end of the housing 1 away from the part to be tested, and the heating element 2 is arranged in the receiving hole 13. Specifically, along the height direction of the part heat resistance detection tooling 100, a receiving hole 13 is provided on the lower end wall of the housing 1, and the receiving hole 13 is configured as a blind hole. In some specific embodiments, the receiving hole 13 can penetrate through the connecting portion 11 and extend into the supporting portion 12.

[0057] By providing the receiving hole 13 on the lower end wall of the housing 1, and the receiving hole 13 being configured as a blind hole, and arranging the heating element 2 in the receiving hole 13, it is possible to prevent the heating element 2 from directly heating the part to be tested, avoid the local area of the part to be tested having too high a temperature, resulting in cracks in the part to be tested, reduce the scrapping quantity of the part to be tested when using the part heat resistance detection tooling 100 to detect the part to be tested, and further reduce the manufacturing cost of the part assembly.

[0058] Refer to Figure 1 and Figure 2, in some embodiments of the present application, the part heat resistance detection tooling 100 may further include: an electrical connector 3. A connection hole 14 is provided on the outer peripheral wall of the housing 1. In some specific embodiments, the connection hole 14 may be provided on the outer peripheral wall of the connection portion 11. In some other specific embodiments, the connection hole 14 may be provided on the outer peripheral wall of the support portion 12. It should be noted that when the support portion 12 extends into the part to be tested, the connection hole 14 is located outside the part to be tested.

[0059] Moreover, the electrical connector 3 is disposed in the connection hole 14. The electrical connector 3 is electrically connected to the heating element 2 and is adapted to be electrically connected to a power source.

[0060] Specifically, the power source can be electrically connected to the electrical connector 3 through a wire. The power source supplies power to the heating element 2 through the electrical connector 3. When the heating element 2 is disposed in the housing 1 and the housing 1 is fixedly connected to the installation wall surface, compared with the power source being directly electrically connected to the heating element 2, such an arrangement can reduce the difficulty of electrically connecting the power source and the heating element 2, thereby improving the use experience of the part heat resistance detection tooling 100.

[0061] Referring to Figure 1 and Figure 2 , in some embodiments of the present application, the connection hole 14 is configured as an oval hole. By configuring the connection hole 14 as an oval hole, the electrical connector 3 can be configured as an electrical connector 3 with a Type-C interface. The power source can be electrically connected to the electrical connector 3 through a wire provided with a Type-C interface. Compared with the power source being electrically connected to the electrical connector 3 through a dedicated wire, such an arrangement can reduce the difficulty of electrically connecting the power source and the electrical connector 3, thereby improving the usability of the part heat resistance detection tooling 100.

[0062] In some embodiments of the present application, the part heat resistance detection tooling 100 may further include: a temperature detection component for detecting the temperature of the part to be tested. Specifically, when the heating element 2 heats the part to be tested, the operator uses the temperature detection component to detect the temperature of the part to be tested in real time, thereby avoiding the part to be tested from melting due to too high a temperature, and further improving the working reliability of the part heat resistance detection tooling 100.

[0063] In some specific embodiments, the temperature detection component may be a thermocouple, but the present application is not limited thereto. The temperature detection component may also be an infrared temperature sensor, etc.

[0064] In some embodiments of the present application, the part heat resistance detection tooling 100 may further include: a timer, which is used to calculate the heating time of the part to be tested. Specifically, when the heating element 2 heats the part to be tested, the operator uses the timer to calculate the time for the heating element 2 to heat the part to be tested, so as to avoid the heating time of the heating element 2 heating the part to be tested being too long, and avoid the temperature of the part to be tested being too high, resulting in the melting of the part to be tested. Furthermore, the working reliability of the part heat resistance detection tooling 100 can be improved.

[0065] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
