Description

Technical Field

[0001] This utility model relates to the field of metal sampling technology, and in particular to a metal sampling device for gearbox quality inspection. Background Technology

[0002] In the mechanical equipment operating system, the gearbox, as the core component for power transmission and speed regulation, directly determines the overall operating efficiency, safety performance, and service life of the machine due to its quality and stability. Therefore, conducting comprehensive and accurate quality inspection of the gearbox is a crucial link in industrial production and equipment maintenance. Operators will select the specifications of the sampling drill bit (such as diameter and cutting edge type, matching special drill bits for different housing materials such as cast iron and aluminum alloy) according to the gearbox housing and inspection requirements, and perform drilling operations. The samples obtained in this way can be directly used for several subsequent key inspection items: for example, by analyzing the sample composition through spectral analysis, verifying whether the housing material meets the alloy ratio required by the design; by observing the sample cross-section through a metallographic microscope, checking for internal defects such as casting porosity and slag inclusions; and by testing the surface hardness of the sample with a hardness tester, determining whether the heat treatment process of the housing material meets the standards. When drilling and sampling gearbox housings, workers typically use a handheld electric drill with a sampling drill bit. However, gearbox housings are generally irregularly shaped, and traditional fixing fixtures, due to structural limitations, cannot precisely fit these irregular housings, making stable fixation impossible. This problem directly makes the drilling and sampling process very cumbersome: workers need to spend extra effort adjusting the housing position, increasing labor intensity and making it easy for even slight housing movement to affect drilling accuracy. This results in unstable sample quality, potentially interfering with the accuracy of subsequent test results and causing inconvenience to gearbox quality inspection. Utility Model Content

The lifting assembly 402 includes a column 4021, a threaded rod 4022, a support beam 4023, and a servo motor 4024. The lower end of the column 4021 is fixedly connected to the front and rear sides of the support plate 3, and the upper end of the column 4021 is fixedly connected to the fixed frame 401. At the lower part of the fixed frame 401, the front and rear ends of the support beam 4023 are slidably connected to the outer periphery of the column 4021. The middle part of the support beam 4023 is threadedly connected to the outer periphery of the threaded rod 4022. The lower end of the threaded rod 4022 is rotatably connected to the middle of the left and right sides of the support plate 3. The upper end of the threaded rod 4022 is rotatably connected to the middle of the left and right sides of the fixed frame 401. The servo motor 4024 is installed on the upper part of the fixed frame 401. The lower output end of the servo motor 4024 passes through the fixed frame 401 and is fixedly connected to the upper end of the threaded rod 4022. Limit switches are installed on the upper and lower sides of the support beam 4023. The pressing assembly 407 includes a pressing plate 4071, a cylinder 4072 and a pressing block 4073.

[0015] Specifically, the explosion-proof glass double door 5 at the front of the sampling chamber 1 is opened, and the gearbox housing to be sampled is placed on the support plate 3. Then, according to the irregular structure and size of the housing, the clamping mechanism 4 is adjusted, and the servo motors 4024 on the upper part of the fixed frame 401 in the lifting assembly 402 are started. The two servo motors 4024 are of the same specification and model and are uniformly controlled by an external terminal. The servo motors 4024 drive the threaded rod 4022 to rotate, so that the support beam 4023, which is threadedly connected to the threaded rod 4022, slides up and down along the column 4021 until the crossbeam 403 is adjusted to a suitable height.

The two servo motors 4024 are of the same specification and model and are uniformly controlled by an external terminal. The servo motor 4024 drives the threaded rod 4022 to rotate, so that the support beam 4023, which is threadedly connected to the threaded rod 4022, slides up and down along the column 4021 until the crossbeam 403 is adjusted to a suitable height. The limit switches on the upper and lower sides of the support beam 4023 can prevent the support beam 4023 from sliding up and down. 023 Overtravel movement; then push the pressing component 407, so that the front part of the pressing component 407 slides along the guide rail 405 at the lower part of the crossbeam 403 through the locking device 406 and the rear part slides along the slider 404, moving the pressing component 407 to the position to be fixed in the housing. Then the position of the pressing component 407 is fixed by the locking device 406. After that, operate the cylinder 4072 on the upper part of the pressing plate 4071 in the pressing component 407. The output end of the cylinder 4072 pushes the pressing block 4073 down. The rubber pad on the outer periphery of the pressing block 4073 avoids damage to the housing. At the same time, the pressing force is controlled by the pressure sensor to achieve a stable clamping of the irregular housing.
