Description

Technical Field

[0001] This utility model relates to the field of magnesium alloy processing and testing, specifically to a magnesium alloy cross-section evaluation device. Background Technology

[0002] Magnesium alloys are alloy materials based on magnesium, formed by adding other elements (such as aluminum, zinc, manganese, rare earth elements, etc.). Due to their lightweight, high strength, good damping properties, and ease of processing, they are widely used in the automotive, aerospace, electronics, and medical fields. The processing of magnesium alloys includes a cutting process; after cutting, a cross-section exists, necessitating an assessment of the flatness of the cross-section.

[0003] Patent CN110608658A provides a flatness testing device and method. The testing device includes a support assembly and a measuring assembly. The measuring assembly includes: a measuring plate, which is detachably mounted on the support assembly, and has a through-hole for mounting the testing platform; a fine grinding testing platform, which is embedded in the testing platform mounting hole, and has a through-hole for measuring; and a flatness testing unit, which includes a flatness detector and a measuring needle, the measuring needle being able to pass through the measuring hole and partially extend out of the fine grinding testing platform.

[0004] This flatness testing device presses the part to be tested so that the end face of the part is in close contact with the end face of the precision grinding testing platform, and then tests the flatness of the upper end face of the part. However, when using this flatness testing device, it is necessary to ensure that the end face of the part to be tested and the end face of the precision grinding testing platform can be in perpendicular contact, and that the bottom contact surface of the part to be tested is flat and has high flatness, so as not to affect the measurement of the other end. Otherwise, if the bottom surface of the part to be tested is not flat, it will also affect the measurement of the flatness of the top. Utility Model Content

[0005] The purpose of this invention is to provide a magnesium alloy cross-section evaluation device that can quickly measure the inclination of the cut surface of a magnesium alloy cross-section.

[0006] To achieve the above objectives, this utility model provides a magnesium alloy cross-section evaluation device, comprising a base, a first frame, a first guide plate, and a second frame arranged sequentially in the height direction. The rear sides of the base, the first frame, and the second frame are fixedly connected by a back frame. A second guide plate is provided inside the first frame. Multiple first through holes are arranged in a matrix on the first guide plate. Multiple second through holes are provided on the second guide plate, each corresponding to one of the first through holes in the vertical direction. A light rod is slidably inserted into the first and second through holes arranged coaxially. A spring is sleeved on the light rod between the first and second guide plates. A limiting ring is fixedly sleeved on the light rod above the spring. Multiple ranging heads pointing towards the lower end face of the light rod are provided on the base.

[0007] Preferably, the upper surface of the base is provided with a lower groove, and the ranging head is disposed in the lower groove.

[0008] Preferably, the four corners of the first guide plate are connected to the first frame via first support columns.

[0009] Preferably, the front end of the first frame is connected to the base via a second support column.

[0010] Preferably, the upper end of the optical rod is rounded.

[0011] Preferably, the inner side of the second frame is provided with multiple notches, and a guide wheel is provided in the notch, the wheel surface of the guide wheel protruding from the inner side of the second frame.

[0012] Preferably, each side of the second frame is provided with at least two guide wheels.

[0013] Preferably, the second guide plate includes two partitions spaced apart, with a gap between the two partitions.

[0014] According to the above technical solution, this utility model provides a magnesium alloy cross-section evaluation device, comprising a base, a first frame, a first guide plate, and a second frame arranged sequentially in the height direction. The rear sides of the base, the first frame, and the second frame are fixedly connected by a back frame. A second guide plate is provided inside the first frame. Multiple first through holes are arranged in a matrix on the first guide plate. Multiple second through holes are provided on the second guide plate, which correspond one-to-one with the first through holes in the vertical direction. A light rod is slidably inserted into the first and second through holes arranged coaxially. A spring is sleeved on the light rod between the first guide plate and the second guide plate. A limiting ring is fixedly sleeved on the light rod above the spring. Multiple measuring heads pointing towards the lower end face of the light rod are provided on the base.

[0015] The usage and beneficial effects of this magnesium alloy cross-section evaluation device are as follows: During testing, the cross-section of the magnesium alloy to be tested is placed downwards and inserted along the spatial guide in the middle of the second frame. The side of the magnesium alloy slides against the inner wall of the second frame. At this time, the bottom cross-section of the magnesium alloy to be tested is pressed against the upper end of multiple light rods. The magnesium alloy to be tested is supported by multiple springs. When the magnesium alloy cross-section is tilted, the downward movement distance of each light rod is different. By measuring the distance to the bottom of the corresponding light rod with multiple distance measuring heads, the displacement of the light rod corresponding to the cross-section position can be obtained. The displacement is output to the computer to calculate the slope of the cross-section.

Detailed Implementation

[0024] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0025] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0026] See Figures 1-4 The magnesium alloy cross-section evaluation device shown comprises a base 1, a first frame 3, a first guide plate 5, and a second frame 9 arranged sequentially in the height direction. The rear sides of the base 1, the first frame 3, and the second frame 9 are fixedly connected by a back frame 11. A second guide plate 6 is provided inside the first frame 3. The first guide plate 5 has multiple first through holes arranged in a matrix. The second guide plate 6 has multiple second through holes that correspond one-to-one with the first through holes in the vertical direction. A light rod 8 is slidably inserted into the first and second through holes arranged coaxially. A spring 7 is sleeved on the light rod 8 between the first guide plate 5 and the second guide plate 6. A limiting ring 16 is fixedly sleeved on the light rod 8 above the spring 7. A plurality of measuring heads 13 pointing to the lower end face of the light rod 8 are provided on the base 1.

[0027] By implementing the above technical solution, during testing, the cross-section of the magnesium alloy to be tested is placed downwards and inserted along the space guide in the middle of the second frame 9. The side of the magnesium alloy slides against the inner wall of the second frame 9. At this time, the bottom cross-section of the magnesium alloy to be tested is pressed against the upper end of multiple light rods 8. The magnesium alloy to be tested is supported by multiple springs 7. When the cross-section of the magnesium alloy is tilted, the downward movement distance of each light rod 8 is different. By measuring the distance to the bottom of the corresponding light rod 8 by multiple distance measuring heads 13, the displacement of the cross-section position of the light rod 8 can be obtained. The displacement is output to the computer to calculate the slope of the cross-section.

[0028] In this embodiment, a lower groove 14 is provided on the upper surface of the base 1, and the ranging head 13 is disposed in the lower groove 14. With this arrangement, the ranging head 13 can be a laser ranging head 13, which measures the distance by aligning it with the plane at the bottom of the optical rod 8, and uses the difference in distance change as the displacement value of the optical rod 8.

[0029] In this embodiment, the four corners of the first guide plate 5 are connected to the first frame 3 via first support columns 4. The first guide plate 5 is supported by multiple first support columns 4, which keep it a distance away from the second guide plate 6. When no magnesium alloy to be tested is placed, the spring 7 presses the limiting ring 16 upward, causing the limiting ring 16 to press against the bottom surface of the first guide plate 5. When compressed, the limiting ring 16 disengages from the first guide plate 5 and moves downward.

[0030] In this embodiment, the front end of the first frame 3 is connected to the base 1 via a second support column 2. This arrangement provides more stable support for the first frame 3, making the overall structure more stable.

[0031] In this embodiment, the upper end of the optical rod 8 is rounded. This design makes the contact between the optical rod 8 and the cross-section smoother.

[0032] In this embodiment, the inner side of the second frame 9 is provided with a plurality of notches 10, and a guide wheel 12 is disposed within each notch 10. The wheel surface of the guide wheel 12 protrudes from the inner side of the second frame 9. This arrangement allows the guide wheel 12 to roll and contact the side of the magnesium alloy to be tested, improving the smoothness of insertion into the magnesium alloy.

[0033] In this embodiment, each side of the second frame 9 is provided with at least two guide wheels 12. For example, when the second frame 9 is a rectangular frame, two guide wheels 12 are provided on each side.

[0034] In this embodiment, the second guide plate 6 includes two spaced-apart partitions 15, with a gap between the two partitions 15. This arrangement creates a two-layer structure for the second guide plate 6, increasing the stability of guiding the light rod 8.

[0035] In this invention, the outline shape of the second frame 9 is set according to the magnesium alloy being tested, such as a circular second frame 9 or a rectangular second frame 9. The elastic coefficient of the spring 7 is selected according to the weight of the magnesium alloy being tested, so that after the magnesium alloy being tested is pressed against multiple light rods 8, each spring 7 can be in a compressed state.

[0036] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0037] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0038] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
