Description

Technical Field

[0001] The utility model belongs to the technical field of flaw detection of metal castings, and particularly relates to a flaw detection device for metal casting processing and detection. Background Technique

[0002] In the preparation process of some large construction machinery, in order to improve the overall structural strength of some important components, the method of integral casting is adopted for production. Before production and processing, operators often use a metal casting flaw detection device to detect the quality of castings;

[0003] At present, in the production and processing of metal casting plates, it is often necessary to manually operate instruments for flaw detection operations, which takes a long time and affects production efficiency. At the same time, the instruments used need to be frequently repaired to ensure the flaw detection effect, which is not conducive to large-scale flaw detection operations;

[0004] To solve the above problems, a flaw detection device for metal casting processing is proposed in this application. Content of the Utility Model

[0005] The purpose of the utility model is to provide a flaw detection device for metal casting processing, which solves the problems put forward in the above background technique.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is a flaw detection device for metal casting processing, including: the equipment main body and the conveyor belt mechanism inside it, and the processed metal plates are circulated and conveyed on the surface of the equipment main body; a rotating roller is arranged inside one end of the equipment main body, and a plastic washer for automatically detecting defects of the metal plate is arranged on the outer side of the rotating roller. When the plastic washer discovers a defect, it generates plastic deformation by using extrusion force. A laser emitter for detecting the deformation state of the plastic washer is arranged above one end of the rotating roller; a fixing frame is also arranged inside one end of the equipment main body, and an arc plate for extruding the plastic washer to restore it is arranged inside the fixing frame.

[0008] Further, a fixing seat is arranged on the side surface of one end of the equipment main body, and a waveform display for displaying a monitored waveform diagram is arranged on one side of the fixing seat.

[0009] Further, a convex seat for installing the rotating roller is arranged on the other side of one end of the equipment main body.

[0010] Further, an adapter seat for installing the waveform display is arranged on the outer side of the fixing seat.

[0011] Further, an electric telescopic device for adjusting the use position of the adjusting arc plate is arranged inside the fixing frame, and arc-shaped slopes for making the protruding parts of the plastic gaskets retract inward are arranged at both the upper and lower ends inside the arc plate.

[0012] Further, a monitoring part for monitoring the recovery state of the plastic gasket is arranged inside one side of the arc plate.

[0013] Further, a protruding limit protrusion is arranged on the outer side of the rotating roller, and a positioning groove for snap-fitting connection with the limit protrusion to prevent loosening is arranged inside the plastic gasket.

[0014] The utility model has the following beneficial effects:

[0015] When the plastic gasket rotates in the utility model, the rolled metal plate can form plastic deformation by using the extrusion force when encountering defects such as gaps, so that the outer surface of the plastic gasket bulges outward to fill the gap, and then it can be detected by the laser emitter after rotation and separation. Through this, the defective metal casting can be quickly located. Compared with the existing method, the working efficiency can be greatly improved, the investment in labor costs can be reduced, and the frequent maintenance of the instrument can be avoided, which is beneficial to the flaw detection process of mass production operations;

[0016] After the arc plate is pushed out by the electric telescopic device in the utility model, when the protruding part of the plastic gasket rotates to the inside, it can be automatically tightened to restore to a circular structure, and then the monitoring part is used for monitoring to timely detect abnormalities. After such treatment, a cyclic flaw detection operation can be formed, and the automatic flaw detection operation can be realized without manual frequent operation of the instrument, making the equipment more practical.

[0017] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Please refer to Figures 1-4 As shown, the present utility model is a flaw detection device for metal casting processing, including: an equipment main body 1 and a conveyor belt mechanism inside it. The surface of the equipment main body 1 circulates and conveys the processed metal plate 2;

[0028] Inside one end of the equipment main body 1, a rotating roller 3 is provided. Outside the rotating roller 3, a plastic washer 4 for automatically detecting defects of the metal plate 2 is provided. When the plastic washer 4 detects a defect, it generates plastic deformation using the extrusion force. Above one end of the rotating roller 3, a laser emitter 10 for detecting the deformation state of the plastic washer 4 is provided;

[0029] Inside one end of the equipment main body 1, a fixing frame 5 is also provided. Inside the fixing frame 5, an arc plate 11 for extruding the plastic washer 4 to restore it is provided;

Through the plastic deformation characteristics and the cyclic flaw detection method during rotation, the flaw detection operation of the casting plate body can be carried out continuously, and the defect position and shape can be detected in time. A continuous automatic flaw detection operation can be formed without manual intervention.

[0031] Among them, a fixed seat 6 is arranged on one side surface of the equipment main body 1, and a waveform display 7 for displaying and monitoring the waveform diagram is arranged on one side of the fixed seat 6, so that the detected defects are magnified in the form of a waveform diagram for easy observation by the staff.

[0033] Among them, an adapter seat 9 for installing the waveform display 7 is arranged on the outside of the fixed seat 6, and a receiving plate mechanism for receiving laser signals is arranged on the inside of the fixed seat 6.

[0034] Among them, an electric telescopic device 12 for adjusting the use position of the adjusting arc plate 11 is arranged on the inside of the fixing frame 5.

[0036] Among them, a protruding limit protrusion 15 is arranged on the outside of the rotating roller 3, and a positioning groove 16 for snap-connecting with the limit protrusion 15 is arranged on the inside of the plastic gasket 4 to keep the plastic gasket 4 in a stable working state under the action of rotational force and extrusion force.

[0037] It can be understood that the utility model can realize continuous cyclic flaw detection operation without manual frequent operation of the instrument, accurately monitor the location of defects, improve work efficiency while reducing the input costs of equipment and labor, and is conducive to flaw detection in mass production operations.

[0038] A specific application of the operation process of this embodiment is as follows: When in use, first, the rotation of the rotating roller 3 drives the plastic washer 4 to rotate and extrude the surface of the metal plate 2. When defects such as gaps are found, the plastic washer 4 automatically bulges and deforms outward under the extrusion force. Subsequently, when it rotates away from the metal plate 2, it is detected by the laser emitted by the laser emitter 10. The amplified waveform is sent to the waveform display 7 to notify the staff of the structural state of the metal plate 2. Further, after adjusting the arc-shaped plate 11 to a predetermined position by the electric telescopic device 12, the arc-shaped slope 14 can automatically extrude the protruding part of the plastic washer 4 to make it shrink back to a circular shape, and then perform the next set of flaw detection operations. Through this, a cyclic flaw detection operation is formed, without the need for manual long-term operation of the instrument, nor frequent maintenance of the equipment, and high-efficiency flaw detection operations can be achieved, greatly improving the practical performance of the equipment.
