Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy production, in particular to an aluminum alloy visual detection component. Background Art

[0002] Grain size is a measure of the size of the grains. Grain size can be expressed by the average area or average diameter of the grains, and is divided into 8 grades. When testing the grain size of existing aluminum alloys, it is necessary to first corrode the aluminum alloy material with an etchant. Then, after corrosion, the aluminum alloy material will show clear grain boundaries. Finally, the grain size grade is determined based on the displayed grain boundaries and classified according to its grade standard.

[0003] At present, the commonly used methods for measuring grain size are comparison method, area method and intercept method. The comparison method determines the grain size grade by comparing with the standard series rating chart. The comparison method has the following defects: First, compared with the other two methods, the deviation of the comparison method in evaluating grain size is larger. In particular, the current evaluators directly use visual observation and compare with the standard series rating chart, and the unclear grain boundary will also affect the deviation result of the evaluation; second, long-term direct visual comparison and evaluation of grain size grade is easy to cause visual fatigue of the evaluators, which in turn affects the judgment of grain size grade and the work efficiency of the evaluators.

[0021] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0022] like Figure 1-2 As shown, an aluminum alloy visual inspection component of the embodiment includes a detection bracket 1, an amplifying bracket 3 connected to the detection bracket 1 through a first connecting rod 2, and the axes of the detection bracket 1, the first connecting rod 2 and the amplifying bracket 3 are perpendicular to each other; the two opposite sides of the detection bracket 1 are correspondingly provided with a to-be-tested piece positioning seat 4 and a standard piece positioning seat 5, and the two ends of the amplifying bracket 3 extending along the length direction are rotatably connected with an image magnifying device 7.

[0023] The positions of the test piece 10 and the standard part are fixed by setting a test piece positioning seat 4 and a standard part positioning seat 5; by setting an image magnifying device 7, the image is magnified to facilitate observation and grain size classification, reduce eye fatigue, improve work efficiency, reduce evaluation errors, and improve the accuracy of grain size grading evaluation; by setting a detection bracket 1, a first connecting rod 2 and an amplifying bracket 3 and connecting and cooperating with each other, the positional relationship between the test piece 10 and the image magnifying device 7, and the standard part and the image magnifying device 7 is determined to adapt to the observation angle and posture of the evaluator, thereby improving work efficiency.

[0024] In this embodiment, an image magnifying device 7 is respectively disposed on the under-test piece positioning seat 4 and the standard piece positioning seat 5 along the axial direction of the first connecting rod 2 to magnify, compare and observe the two.

[0025] like Figure 1-2 As shown, in another preferred embodiment, both the positioning seat 4 of the workpiece to be tested and the positioning seat 5 of the standard part are provided with a tightening member 6, and the tightening member 6 includes two opposite abutting portions 601, and the two abutting portions 601 are configured to abut two surfaces opposite to the thickness direction of the workpiece; an adjusting member 602 is provided between the two abutting portions 601, and the adjusting member 602 is configured to adjust the spacing between the two abutting portions 601.

[0026] The tightening member 6 is used to fix the test piece 10 of different thicknesses and adjust the position of the test piece 10 along the axial direction of the first connecting rod 2. In this embodiment, the two abutting portions 601 can move toward or away from each other; the abutting portion 601 fixes the test piece 10; the adjusting member 602 adjusts the position of the test piece 10 along the axial direction of the first connecting rod 2, that is, adjusts the distance between the test piece 10 and the image magnifying device 7.

[0027] Preferably, along the axial direction of the first connecting rod 2 , the distance between the test surface of the test piece 10 and the image magnifying device 7 is equal to the distance between the standard surface of the standard piece and the image magnifying device 7 .

[0028] like Figure 1 As shown, in another preferred embodiment, the detection bracket 1 is fixedly connected to the first connecting rod 2, and the first connecting rod 2 is fixedly connected to the amplifying bracket 3; the first connecting rod 2 is a telescopic rod.

[0029] In this embodiment, the first connecting rod 2 is configured as a telescopic rod, and the distance between the detection bracket 1 and the amplification bracket 3 along the axial direction of the first connecting rod 2 is adjusted to facilitate obtaining a clear grain size image.

[0030] like Figure 1 As shown, in another preferred embodiment, the magnifying bracket 3 is a telescopic structure; the magnifying bracket 3 and the image magnifying device 7 are hinged via a pin.

[0031] In this embodiment, the plane where the image magnifying device 7 is located is parallel to the plane where the measured surface of the test piece 10 is located, and the image magnifying device 7 moves in the plane where it is located to achieve all-round magnification, comparison and detection of the test piece 10. The plane where the image magnifying device 7 is located is the plane formed by the axial direction of the magnifying bracket 3 and the axial direction of the detection bracket 1. The image magnifying device 7 rotates around the pin in the plane where it is located. During the rotation process, there is at least one position where the highest point or the lowest point of the image magnifying device 7 along the axial direction of the detection bracket 1 exceeds the test piece 10, thereby achieving magnification detection along the axial direction of the detection bracket 1.

[0032] By providing the zoom bracket 3 with a telescopic structure, the image magnifying device 7 can move along the axial direction of the zoom bracket 3 and perform observation; through the hinged connection between the zoom bracket 3 and the image magnifying device 7, the image magnifying device 7 can magnify and detect the object to be tested 10 in the axial direction of the detection bracket 1.

[0033] like Figure 1 , Figure 3 As shown, in another preferred embodiment, a workpiece limiting frame 401 is connected to the side of the workpiece positioning seat 4 facing the magnifying bracket 3, and the workpiece limiting frame 401 is configured to limit the axial movement of the workpiece 10 to be tested along the first connecting rod 2; a blanking channel 402 is arranged between the workpiece positioning seat 4 to be tested and the workpiece limiting frame 401 along the axial direction of the first connecting rod 2; a blanking stopper 403 is removably arranged in the blanking channel 402, and the upper surface of the blanking stopper 403 is coplanar with the upper surface of the workpiece positioning seat 4 to be tested, and the blanking stopper 403 is configured to limit the axial movement of the workpiece 10 to be tested along the detection bracket 1; it also includes a pushing drive device 8, and the pushing drive device 8 has a driving part 801 that pushes against the workpiece 10 to be tested along the axial direction of the first connecting rod 2.

[0034] This embodiment automatically replaces the test piece 10 to achieve batch testing and evaluation. Compared with one-to-one individual comparison testing, the tightening member 6 of the test piece positioning seat 4 needs to be tightened and opened frequently, and the workpiece is frequently placed and removed. This embodiment reduces the frequent replacement and fixation, and improves work efficiency.

[0035] Optionally, the push drive device 8 is a pneumatic cylinder or an oil cylinder.

[0036] In this embodiment, along the axial direction of the first connecting rod 2, the test piece positioning seat 4 can place multiple test pieces 10. The material drop channel 402 can accommodate a single test piece 10 to fall; the positional relationship between the material drop stopper 403 and the test piece positioning seat 4 is set so that the test piece 10 can be smoothly transferred from the test piece positioning seat 4 to the material drop stopper 403.

[0037] like Figure 1 , Figure 3 and Figure 4As shown, in this embodiment, the working steps of batch detection of sight lines of the positions to be measured in the aluminum alloy visual inspection assembly are as follows:

[0038] Step 1: Place multiple pieces to be tested 10 on the piece to be tested positioning seat 4, with one surface of the piece to be tested 10 along its thickness direction facing the image magnifying device 7; a group of opposite sides of the piece to be tested 10 along the axial direction of the magnifying bracket 3 abut against the workpiece limiting frame 401, and another group of opposite sides of the piece to be tested 10 along the axial direction of the detection bracket 1 also abut against the workpiece limiting frame 401.

[0039] Step 2: The driving part 801 of the material pushing driving device 8 abuts against a surface of the last test piece 10 along its thickness direction. The material pushing driving device 8 is started to push the multiple test pieces 10 toward the workpiece limiting frame 401 until the first test piece 10 abuts against the workpiece limiting frame 401 in the circumferential direction;

[0040] When the workpiece 10 is completely in contact with the workpiece limit frame 401 , the workpiece 10 is located above the blanking channel 402 , and the blanking blocking member 403 in the blanking channel 402 is in contact with the workpiece 10 . The workpiece 10 stays for a while, and the evaluator performs comparative testing.

[0041] Step 3: After the inspection of a piece to be tested 10 is completed, the material falling blocking member 403 is removed, so that a space capable of accommodating the falling of the piece to be tested 10 is formed in the material falling channel 402, and the piece to be tested 10 falls.

[0042] Step 4: After a workpiece 10 falls, the material blocking member 403 returns to a position where it can abut against the workpiece 10, and the material pushing drive device 8 is started to push the next workpiece 10 to the top of the material dropping channel 402. The operations of steps 1 to 4 are repeated.

[0043] like Figure 1 , Figure 3 As shown, in another preferred embodiment, the material dropping channel 402 includes two first inner walls 4021 opposite to each other along the axial direction of the first connecting rod 2, and the two first inner walls 4021 are provided with a guide groove 4022 extending along the axial direction of the magnifying bracket 3, and the material dropping blocking member 403 is matched with the guide groove 4022 and moves along the guide groove 4022.

[0044] In this embodiment, the length of the blanking channel 402 along the axial direction of the amplifying bracket 3 is greater than the length of the workpiece 10 to be tested and greater than the distance between two opposite sides of the workpiece limiting frame 401 .

[0045] In this embodiment, two material drop blocking members 403 are arranged in the material drop channel 402, and the two material drop blocking members 403 are respectively arranged at the two ends of the material drop channel 402 along the axial direction of the magnifying bracket 3. When the workpiece 10 to be tested needs to stay above the material drop channel 402 for magnified observation, the distance between the two material drop blocking members 403 along the axial direction of the magnifying bracket 3 is less than the length of the workpiece 10 to be tested; when the test is completed and the workpiece 10 to be tested needs to fall, the two material drop blocking members 403 are moved along the guide groove 4022 in a direction away from the workpiece limit frame 401 until the distance between the two material drop blocking members 403 along the axial direction of the magnifying bracket 3 is greater than the length of the workpiece 10 to be tested.

[0046] like Figure 4 As shown, in another preferred embodiment, a workpiece spacer 9 is further provided, and the workpiece spacer 9 is configured to be spaced and clamped at the edges of adjacent workpieces 10 to be tested.

[0047] By providing the workpiece spacer 9 , it is prevented that the first workpiece 10 to be tested rubs against the second workpiece 10 to be tested and causes scratches when the first workpiece 10 falls from the blanking channel 402 , thereby affecting the detection effect of the second workpiece 10 to be tested.

[0048] Optionally, the workpiece spacers 9 are arranged on two opposite sides of the workpiece to be tested 10 , or on the circumferential edge of the workpiece to be tested 10 .

[0049] In this embodiment, the material dropping channel 402 can allow a single workpiece 10 to be tested and a workpiece spacer 9 to drop down.

[0050] like Figure 1-4 As shown, the workflow of the utility model is as follows:

[0051] Step 1: Place the standard part on the standard part positioning seat 5, with one of the two opposite surfaces of the standard part along its thickness direction facing the image magnifying device 7; drive the tightening member 6 to work and adjust the position of the fixed standard part. If the structure of the positioning seat 4 of the test piece is the same as that of the standard part positioning seat 5, the process of the test piece 10 refers to the standard part. At this time, the test piece 10 and the standard part are placed one by one on the opposite sides of the detection bracket 1 for comparative detection.

[0052] Along the axial direction of the first connecting rod 2 , when the distance from the standard component to the amplifying bracket 3 is equal to the distance from the under-test component 10 to the amplifying bracket 3 , the positions of the standard component and the under-test component 10 are fixed and immovable.

[0053] Step 2: Adjust the first connecting rod 2, and then adjust the distance from the axial amplification bracket 3 to the standard part and the test piece 10 along the first connecting rod 2, so as to obtain a clear grain size image.

[0054] Step 3: Adjust the length of the magnifying bracket 3 on one side of the standard part, and keep the side where the standard part is located fixed and immobile; then, adjust the length of the magnifying bracket 3 on one side of the test piece 10 and rotate the position of the image magnifying device 7 on that side in real time to achieve all-round detection and evaluation of the test piece 10.

[0055] After the test is completed, the test piece 10 on the test piece positioning seat 4 is replaced, and the above steps 1 to 3 are repeated.

[0056] The above steps are applicable to the detection of one-to-one comparison between standard parts and test pieces 10; if one-to-N batch comparison detection between standard parts and test pieces 10 is to be achieved, the structure of the test piece positioning seat 4 is adjusted, and the test piece 10 is driven by the push drive device 8 to move toward the image magnifying device 7. The working steps of batch detection refer to the operations of steps 1 to 4 of the above embodiment.

[0057] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
