Description

TECHNICAL FIELD

[0001] The application relates to the technical field of spectral analysis equipment, in particular to a spectral device for casting part detection. BACKGROUND

[0002] As a basic part of modern industry, the quality of a casting part directly depends on the accurate control of material composition. Spectral analysis instruments provide rapid and accurate composition detection capability and become indispensable quality guarantee tools in casting production. From raw material inspection to smelting monitoring and finished product detection, spectral analysis technology runs through the whole casting process and provides strong support for improving casting performance, reducing the waste rate and optimizing process parameters.

[0003] Meanwhile, after the production of a casting part is completed, the casting part needs to be sampled (for example, into a cylindrical shape) to meet the requirements of the instrument, and then the spectral measurement instrument is used to detect and analyze various metal contents. In actual detection, in order to improve the representativeness of data, multi-point detection of the sample is often required. However, the operation mode of the traditional spectrometer has an efficiency bottleneck: after each detection is completed, the metal rod (electrode holder) for fixing the sample needs to be manually lifted, the sample position needs to be adjusted, and then the sample needs to be pressed again before the next excitation. This process involves repetitive mechanical operations, which not only increases the cost of manual intervention, but also significantly reduces the detection efficiency. Therefore, the application provides a spectral device for casting part detection. SUMMARY

Detailed Implementation

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1: Please refer to Figures 1-5 The present invention provides a technical solution: a spectroscopic device for testing castings, comprising a spectrometer body 1 and a test stage 11 mounted on the spectrometer body 1, wherein a metal rod 12 is provided on the test stage 11, and further comprising:

[0040] The movable support 2 is mounted on the spectrometer body 1 and connected to the metal rod 12;

[0041] The pusher 3 is mounted on the spectrometer body 1 and connected to the movable support 2, and is used to drive the movable support 2 and the metal rod 12 to move to contact the sample.

[0042] Positioning ring 4 is set on test stage 11. Multiple rectangular rubber strips 48 are fixedly connected inside positioning ring 4 for temporarily fixing the sample. Specifically, the cylindrical sample is inserted into positioning ring 4 and pressed down to the bottom (the sample is in contact with test stage 11), and then the electric motor is started to push the metal rod 12 to contact the sample.

[0043] Adjustment component 5 is set on test stage 11 and connected to positioning ring 4. It is used to move the sample so that its test point moves from the center to its concentric circle, and then drives the sample to rotate around its center, switching test points at different angles on the concentric circle.

[0044] Rotating component 6 is set on test stage 11 and connected to positioning ring 4, used to drive positioning ring 4 and sample to rotate around test point as center;

[0045] Specifically, this device can move the sample by adjusting component 5 to automatically switch test points, which is simple, convenient and efficient. At the same time, the pusher 3 drives the metal rod 12 to detach from the sample when the sample moves to avoid friction damage. In addition, when performing spectral tests, this device can use the rotating component 6 to drive the sample to rotate around the test point to improve the uniformity of the test.

[0046] Meanwhile, the device's design of "central reference + multi-point verification" first detects the center of the cylindrical sample and then detects multiple points on the concentric circle, which balances detection efficiency and data reliability.

[0047] Specifically, the advantages of this design are:

[0048] First, establish a benchmark reference. The center of the circle is the core area of ​​sample preparation (such as the casting start point). Its composition / structure can reflect the initial state of the material or process parameters (such as melting uniformity). By detecting the center, it is possible to verify whether the basic performance of the sample meets the standards and serve as a reference benchmark for subsequent testing.

[0049] Secondly, it can efficiently locate anomalies. If there are defects such as component segregation or impurities at the center, it may indicate that there are process problems in the entire sample (such as uneven stirring). In this case, there is no need for further multi-point testing to determine that it is unqualified, thus improving the testing efficiency.

[0050] Third, optimize the multi-point detection strategy. After confirming that the center is qualified, the material uniformity (such as radial composition gradient) can be analyzed by multi-point detection of concentric circles, avoiding blind and comprehensive detection and reducing workload.

[0051] It should be noted that the metal castings tested by this device can be heavy truck chassis castings, specifically frame castings, axle castings, suspension castings, steering castings, or engine mount castings. Among them, frame castings can be integral crossbeams or frame body castings; axle castings can be axle housings, wheel hubs, or brake hubs; suspension castings can be leaf spring seats, support seats, and balance shaft housings, etc.; steering castings can be steering gear housings or steering knuckles; and engine mount castings can be engine mounts. During specific testing, samples will be taken from the corresponding castings. If the casting thickness is different, the metal rod 12 of this device is threadedly connected to the moving bracket 2, so the position of the metal rod 12 can be manually adjusted to ensure that the end of the metal rod 12 can contact casting samples of different thicknesses, thus ensuring smooth testing.

[0052] The pusher 3 includes a sliding plate 31 disposed on one side of the test bench 11. One end of the sliding plate 31 is connected to the movable bracket 2, and an electric push rod 32 is fixedly connected to the spectrometer body 1. The extended end of the electric push rod 32 is fixedly connected to the sliding plate 31 and is used to drive the metal rod 12 to move.

[0053] The sliding plate 31 is rotatably connected to the movable bracket 2 via a rotating shaft. A sliding sleeve 49 is fixedly connected to one side of the sliding plate 31. A pull rod 51 is provided on one side of the sliding plate 31, which slides through the sliding sleeve 49. A connecting rod 52 is rotatably connected to the movable bracket 2 via a rotating shaft. A spring 53 is sleeved on the pull rod 51, with its two ends fixed to the pull rod 51 and the sliding sleeve 49 respectively.

[0054] Furthermore, a sliding sleeve 54 is fixedly connected to the electric push rod 32. One end of the pull rod 51 passes through the sliding sleeve 54 and is fixedly connected to a limiting protrusion 55. Specifically, when the electric push rod 32 is activated, it drives the sliding plate 31 to rise while simultaneously causing the metal rod 12 to detach from the sample. During this process, the pull rod 51 first slides relative to the sliding sleeve 54 until the limiting protrusion 55 contacts and abuts against the sliding sleeve 54, blocking the movement of the pull rod 51. Then, the pull rod 51 moves relative to the sliding plate 31, driving the connecting rod 52 to move. At the same time, the spring 53 is compressed and contracts to provide self-recovery force. The movement of the connecting rod 52 causes the moving bracket 2 and the metal rod 12 to deflect and avoid, thereby facilitating the staff to pick up or install the sample and improving the convenience of the staff's operation.

[0055] The adjustment assembly 5 includes a mounting ring 33 fixedly connected to the test stage 11. A rotating circular plate 34 is rotatably connected inside the mounting ring 33. A shaft 35 is rotatably connected to the rotating circular plate 34 via a bearing. A deflection ring 36 is rotatably connected to the shaft 35 via a bearing. A positioning ring 4 is rotatably connected to the deflection ring 36. An arc-shaped groove 37 is provided on the rotating circular plate 34. The deflection ring 36 is located in the arc-shaped groove 37 and is slidably connected to its inner wall. A driving component 38 is provided on the rotating circular plate 34. In the initial state, the center of the sample is located at the center of the mounting ring 33, that is, the center of the sample is directly aligned with the test point of the device. Then, the driving component 38 first drives the deflection ring 36 to slide along the arc-shaped groove 37 so that the test point of the sample moves from the center to its concentric circle. Then, the sample is rotated around the center to switch test points at different angles on the concentric circle.

[0056] The drive unit 38 includes an L-shaped bracket 39 fixedly connected to the rotating circular plate 34. A drive motor 41 with an output shaft fixedly connected to the L-shaped bracket 39 is fixedly connected to the shaft 35. The drive motor 41 is a self-locking motor used to lock the positioning ring 4 and the deflection ring 36 to prevent them from shifting during detection. A gear disk 43 is fixedly connected to the shaft 35. A plurality of toothed protrusions 44 that mesh with the gear disk 43 are fixedly connected at equal intervals on the positioning ring 4.

[0057] The outer wall of the positioning ring 4 is made of rubber and is used to temporarily fix the deflection ring 36 and the positioning ring 4 through friction.

[0058] Specifically, after the center test of the sample is completed, the device starts the electric push rod 32 to move the metal rod 12 away from the sample, and then starts the drive motor 41 to drive the shaft 35 to rotate. At this time, due to the frictional resistance between the deflection ring 36 and the positioning ring 4, and this frictional resistance is greater than the resistance to deflect the deflection ring 36, the positioning ring 4, and the sample, the rotation of the drive motor 41 will first drive the deflection ring 36 along the arc groove 37 to deflect the positioning ring 4 and the sample into place, so as to switch the test point to the concentric circle of the sample. After that, the drive motor 41 will continue to rotate, which will drive the positioning ring 4 to rotate through the gear, so as to drive the sample to rotate around the center and switch the test point at different angles on the concentric circle.

[0059] The rotating assembly 6 includes a second drive motor 45 fixedly connected to the mounting ring 33. A second gear disk 46 is fixedly connected to the output shaft of the second drive motor 45, and a rotating circular plate 34 is rotatably connected to the mounting ring 33. A plurality of toothed protrusions 47 that mesh with the second gear disk 46 are fixedly and evenly fixedly connected on the rotating circular plate 34. When the second drive motor 45 is started, the second gear disk 46 is rotated, thereby driving the rotating circular plate 34 to rotate, so as to drive the sample to rotate around the test point as the center, thereby improving the uniformity of the test.

[0060] Example 2: Please refer to Figures 6-8 The present invention provides a technical solution: Embodiment 2 is another specific implementation of the adjustment component 5 in Embodiment 1;

[0061] The adjustment assembly 5 includes a mounting ring 33 connected to the test stage 11. A guide rod 56 is fixedly connected inside the mounting ring 33. A sliding ring 57 is slidably connected to the guide rod 56. A positioning ring 4 is rotatably connected to the sliding ring 57. An electric push rod 58 is fixedly connected between the mounting ring 33 and the sliding ring 57. When the electric push rod 58 is activated, it drives the sliding ring 57, the positioning ring 4, and the sample to move so that the test point is switched to the concentric circle of the sample. Then, the drive motor 41 is activated, which drives the positioning ring 4 to rotate through the gear to drive the sample to rotate around the center and switch the test point at different angles on the concentric circle.

[0062] Furthermore, a drive motor 41 is fixedly connected to the sliding ring 57, a gear disk 43 is fixedly connected to the output shaft of the drive motor 41, and multiple toothed protrusions 44 that mesh with the gear disk 43 are fixedly connected at equal intervals on the positioning ring 4.

[0063] Example 3: Please refer to Figures 9-14 The present invention provides a technical solution: Embodiment 3 is another specific implementation of the driving component 38 and the rotating component 6 in Embodiment 1;

[0064] The driving component 38 includes a U-shaped bracket 59 fixedly connected to the rotating circular plate 34. A drive motor 41 with an output shaft fixedly connected to the U-shaped bracket 59 and a shaft 35 is fixedly connected to the shaft 35. A hollow shaft 61 is sleeved on the shaft 35. A gear disk 43 is fixedly connected to the hollow shaft 61. Multiple toothed protrusions 44 are evenly and uniformly fixedly connected on the positioning ring 4. When the gear disk 43 meshes with the toothed protrusions 44 on the positioning ring 4, starting the drive motor 41 can first drive the deflection ring 36 to deflect and then drive the positioning ring 4 to rotate.

[0065] Furthermore, a groove 62 is provided on the shaft 35, and a sliding protrusion 63 with one end located in the groove 62 is fixedly connected inside the hollow shaft 61 to guide and limit the hollow shaft 61 to slide along the shaft 35. A Y-shaped plate 64 is rotatably connected to the hollow shaft 61 through a bearing. A sliding column 65 with one end sliding through the Y-shaped plate 64 is fixedly connected to the U-shaped bracket 59. A spring 66 with both ends fixedly connected to the U-shaped bracket 59 and the Y-shaped plate 64 is sleeved on the sliding column 65. A rectangular lever 67 is fixedly connected to the sliding plate 31. Moving the sliding plate 31 uses the rectangular lever 67 to push the Y-shaped plate 64 to move, so as to drive the gear disk 43 to mesh with the gear protrusion 44 and compress the spring 66 to provide it with self-recovery force. Then, the drive motor 41 is started to drive the shaft 35 to rotate. The rotating assembly 6 includes an internal gear ring 71 fixedly connected to the mounting ring 33.

[0066] Specifically, when the center of the sample is tested, the toothed disk 43 is engaged with the inner toothed ring 71. At this time, the drive motor 41 rotates and drives the toothed disk 43 to roll along the inner toothed ring 71, which in turn causes the sample to rotate around the test point. After the center test is completed, the Y-shaped plate 64 stops above the rectangular lever 67. Then, the electric push rod 32 is started, which drives the metal rod 12 to disengage from the sample. At the same time, the rectangular lever 67 drives the Y-shaped plate 64 to move upward, which in turn drives the toothed disk 43 on the hollow shaft 61 to move upward and engage with the toothed protrusion 44. Subsequently, the drive motor 41 is started again, which first drives the deflection ring 36 to deflect and then drives the positioning ring 4 to rotate.

[0067] Limiting plates 68 are fixedly connected to both branches of the Y-shaped plate 64, and two slots 69 are opened on the rotating circular plate 34. Similarly, two slots 69 are opened on the deflection ring 36, which are used to cooperate with the limiting plates 68 to lock the deflection ring 36 and the rotating circular plate 34. The outer wall of the positioning ring 4 is made of rubber to provide frictional resistance when it rotates relative to the deflection ring 36.

[0068] Specifically, when the gear disc 43 and the internal gear ring 71 are engaged, the limiting plate 68 will be inserted into the slot 69 of the rotating disc 34 and the deflection ring 36 to lock them in place, thereby preventing the deflection ring 36 from shifting and improving the accuracy of the test.
