Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal research and development technology, specifically to a trace detection device for metal product research and development. Background Technology
[0002] Metal product research and development is a process that uses metal materials as the processing object and achieves product upgrades and performance optimization through innovative technologies. Among these, trace detection devices are mainly used to identify and evaluate defects such as scratches and indentations on metal surfaces caused by processing, use, or environmental factors.
[0003] Existing trace detection devices mainly consist of a detection execution module responsible for signal acquisition, a data processing module for data analysis, and a result output and interaction module for displaying results. After the metal product is placed in the detection device, the detection execution module acquires surface trace signals through contact or non-contact methods. The data processing module analyzes and identifies defect features using algorithms, and finally, the result output module presents the results. Its principle is based on the physical signal optical, acoustic, and mechanical conversion and data algorithms to transform the physical characteristics of traces on the metal surface into identifiable detection results.
[0004] Therefore, it has the following shortcomings when in use: it is only suitable for the detection of specific shapes, such as flat plates or cylinders, while spherical or irregularly shaped metal products are easy to move inside the detection device, affecting the detection results. Also, because one side of the metal product is attached to the inner wall of the device, it is impossible to detect all sides of the metal product at one time. It is necessary to scan in sections and readjust, which makes the detection efficiency low. Utility Model Content
[0005] I. Technical problems to be solved
[0006] The technical problem to be solved by this invention is that the applicable shapes of metal products are limited and the detection efficiency is low.
[0007] II. Technical Solution
[0008] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a trace detection device for the research and development of metal products, including a detection box, wherein the front side of the detection box is provided with a rotating and opening box door;
[0009] The detection module is provided in the middle of the inner wall of the detection box and the middle of the inner wall of the box door, and the corners of the upper and lower inner walls of the detection box are respectively provided with limiting mechanisms facing the center of the detection box.
[0010] The limiting mechanism includes opposing support plates connected to the detection box. A rubber rod is connected between the support plates. Multiple protrusions are evenly provided on the side wall of the rubber rod along the circumferential direction. A connecting plate is rotatably sleeved on the rubber rod. The side wall of the connecting plate is provided with a through hole that fits onto the rubber rod. The inner wall of the through hole is provided with a notch that fits onto the protrusion along the circumferential direction. A telescopic rod is connected to one end of the connecting plate facing the center of the detection box. The other end of the telescopic rod is a hemispherical structure. Multiple telescopic rods cooperate to clamp and fix the metal products between them.
[0011] As an improvement, a rubber block is provided on the side of the box door facing the test box, which is attached to the inner wall of the test box.
[0012] As an improvement, the box door has an inverted L-shaped rod on one side edge facing the test box. The L-shaped rod is made of rubber. The front end of the test box has a slot that mates with the L-shaped rod. A stop bar is provided between the left and right inner walls below the slot.
[0013] As an improvement, the telescopic rod includes a sleeve connected to the connecting plate, the inner wall of the sleeve is threaded, and a screw is threadedly inserted into the sleeve, the other end of the screw being a hemispherical structure.
[0014] As an improvement, the number of screws is multiple, and they have different lengths.
[0015] As an improvement, one end of the screw hemispherical structure is fitted with a double-sided adhesive sheet, which is hemispherical in shape.
[0016] III. Beneficial Effects
[0017] The advantages of this utility model compared with the prior art are as follows:
[0018] This invention utilizes multiple limiting mechanisms located at the corners of the upper and lower inner walls of the testing chamber to achieve flexible and stable clamping and fixing of metal products from multiple directions. Whether it is the easy rolling characteristic of spherical products or the irregular contour of irregularly shaped products, a tight fixation can be achieved by adjusting the extension length of the telescopic rod and the clamping angle, completely avoiding the problem of product movement during the testing process. Furthermore, it keeps the product in a suspended clamping state, ensuring that all surfaces of the product are within the signal coverage range of the testing module. This eliminates the need for partitioned scanning and repeated adjustments, shortens the testing process, and significantly improves testing efficiency. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0026] As attached Figure 1-5 As shown, a trace detection device for the research and development of metal products includes a detection box 1. The front of the detection box 1 is provided with a rotating and opening box door 2. The side of the box door 2 facing the detection box 1 is provided with a rubber block 9 that is in contact with the inner wall of the detection box 1, so that the box door 2 and the detection box 1 form a sealed chamber, effectively isolating the influence of the external environment.
[0027] Furthermore, the box door 2 has an inverted L-shaped rod 10 on one side edge facing the detection box 1. The L-shaped rod 10 is made of rubber. The front end of the detection box 1 has a slot 11 that mates with the L-shaped rod 10. A stop bar 12 is provided between the left and right inner walls below the slot 11, so that the L-shaped rod 10 is inserted into the slot 11 and passes through the stop bar 12. Without external force, the box door 2 closes tightly to prevent loosening.
[0028] The detection module 3 is respectively provided in the middle of the inner wall of the detection box 1 and the middle of the inner wall of the box door 2. The detection module includes multi-signal acquisition of vision, laser and ultrasound. After data processing module (not shown in the figure) analyzes and identifies defect features through algorithm, the result is finally presented by the result output module. Its principle is based on physical signal optical, acoustic and mechanical conversion and data algorithm to convert the physical features of the marks left on the metal surface into identifiable detection results.
[0029] The detection box 1 has limiting mechanisms at the corners of its upper and lower inner walls, each facing the center of the detection box 1. Each limiting mechanism includes opposing support plates 4 connected to the detection box 1. A rubber rod 5 is connected between the support plates 4. Multiple protrusions are evenly distributed along the circumferential direction on the sidewall of the rubber rod 5. A connecting plate 6 is rotatably sleeved around the rubber rod 5. The sidewall of the connecting plate 6 has a through hole 7 that fits onto the rubber rod 5. The inner wall of the through hole 7 has a recess along the circumferential direction that mates with the protrusions. This ensures that the angle between the connecting plate 6 and the rubber rod 5 is fixed when no external force is applied. When external force is applied, the protrusions on the rubber rod 5 are compressed, causing the connecting plate 6 to rotate. A telescopic rod 8 is connected to the end of the connecting plate 6 facing the center of the detection box 1. The rotation and fixing of the connecting plate 6 adjusts and fixes the angle of the telescopic rod 8, allowing for telescopic movement. The other end of the rod 8 is a hemispherical structure. The telescopic rod 8 includes a sleeve connected to the connecting plate 6. The inner wall of the sleeve is threaded, and a screw is threaded into the sleeve. The other end of the screw is a hemispherical structure. The length of the telescopic rod 8 can be adjusted by rotating the screw. The hemispherical structure at the other end of the screw can fit perfectly against the metal product, so that multiple telescopic rods 8 can work together to clamp and fix the metal product between them. Whether it is the easy rolling characteristic of spherical products or the irregular contour of irregular products, a tight fixation can be achieved by adjusting the telescopic length and clamping angle of the telescopic rod, which completely avoids the problem of product movement during the inspection process. It also makes the product in a suspended clamping state, ensuring that all surfaces of the product are within the signal coverage range of the inspection module. There is no need for partition scanning and repeated adjustments, which can shorten the inspection process and greatly improve the inspection efficiency.
[0030] Furthermore, there are multiple screws of different lengths, and the appropriate screw length can be selected according to the size of the metal product, thus allowing for a wider range of applicable metal product sizes.
[0031] Furthermore, one end of the screw hemispherical structure is provided with a double-sided adhesive sheet 13. The double-sided adhesive sheet 13 is hemispherical in shape and fits perfectly to be bonded to the end of the screw. The other side can be bonded to metal products, and the fixing effect is further enhanced by the adhesive force.
