Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum material testing technology, and in particular to an aluminum material thickness testing device. Background Technology
[0002] In the aluminum production process, traditional mechanical contact measurement methods are widely used for thickness detection of aluminum materials. This method mainly involves direct contact between mechanical parts and the aluminum material being measured, converting physical deformation or displacement into thickness data.
[0003] However, due to the influence of material properties and processing, the thickness and dimensions of different batches of aluminum may vary. This makes it difficult for traditional mechanical contact measurement methods to guarantee the accuracy, comprehensiveness, and convenience of testing when dealing with different batches of aluminum.
[0004] Firstly, regarding accuracy, due to the differences between batches of aluminum materials (differences in size, thickness, and height), traditional measuring devices cannot be adjusted or can only be adjusted manually, and the lack of a distance measuring structure may lead to significant errors in the measurement results.
[0005] Secondly, in terms of comprehensiveness, traditional mechanical contact measurement can only be performed at a fixed location, which cannot cover every point on the aluminum surface and cannot fully reflect the true thickness distribution of the aluminum.
[0006] In summary, we propose an aluminum material thickness detection device. Utility Model Content
[0007] The purpose of this invention is to overcome the shortcomings of existing technologies and design a new measuring device that can improve detection accuracy and comprehensiveness.
[0008] To achieve the above objectives, the present invention adopts the following technical solution:
[0009] An aluminum thickness detection device includes a detection platform and a contact measuring head. The contact measuring head is mounted on a lifting mechanism, and a front and rear adjustment cylinder is installed on the lifting mechanism. The contact measuring head is installed with the output end of the front and rear adjustment cylinder facing the detection platform.
[0010] A height measuring mechanism is installed on one side of the front and rear adjusting cylinder. The height measuring mechanism includes a connecting sleeve, which is fitted onto a vertical scale. The scale value on the scale extends upwards from the end of the testing platform.
[0011] The top of the testing platform has a measuring groove along its length. Limiting cylinders are provided on both sides of the measuring groove away from the operating end of the testing platform. The output end of the limiting cylinders is provided with a limiting plate along the length of the measuring groove.
[0012] Furthermore, the contact measuring head is selected from dial indicators.
[0013] Furthermore, the lifting mechanism is a lead screw lifting mechanism, and the front and rear adjusting cylinders are mounted on the lead screw nut of the lead screw lifting mechanism via a fixed seat.
[0014] Furthermore, the contact measuring head is mounted on the detection seat, and the contact measuring head is mounted on the output end of the front and rear adjusting cylinders via the detection seat.
[0015] Furthermore, the connecting sleeve is connected to the side of the fixed base via a connecting rod. The connecting sleeve slidably connects to the scale, and its bottom surface is horizontally in contact with the measuring head. Thus, when the lifting mechanism drives the measuring head to rise and fall, the connecting sleeve simultaneously rises and falls on the scale.
[0016] Furthermore, the scale is installed in a secondary groove that is connected to the measuring groove, so that the distance from the starting point of the scale to the connecting sleeve is the same as the distance between the detection head of the contact measuring head and the measuring groove.
[0017] Furthermore, rubber rollers are provided at both ends of the top of the measuring groove and at the center corresponding to the contact measuring head. The rubber rollers are rotatably connected to the groove opened in the measuring groove, and the protrusion height is no more than 0.5cm.
[0018] Furthermore, a gap is left between the limiting plate and the rubber roller, and the limiting cylinder extends and retracts to move the limiting plate closer to the other side of the measuring groove at a distance equal to the width of the aluminum material, with a reserved movement gap of no more than 1cm.
[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] 1. By mounting a contact measuring head (such as a dial indicator) on the lifting mechanism and the front and rear adjusting cylinders, the device can flexibly adjust the position of the measuring head to adapt to the size and shape variations of different batches of aluminum materials. This design overcomes the measurement error problem caused by the lack of a distance measuring structure in traditional mechanical contact measurement methods, and significantly improves the accuracy of detection.
[0021] 2. Because the contact measuring head can move in the front and back directions and its height can be adjusted by the lifting mechanism, and the aluminum material slides left and right on the rubber roller on the measuring groove, the device can measure at multiple positions on the surface of the aluminum material, thus more comprehensively reflecting the true thickness distribution of the aluminum material. This solves the limitation of traditional methods that can only measure at fixed positions.
[0022] 3. By incorporating a height measuring mechanism, including a connecting sleeve and a scale, this device can visually display the height position of the contact measuring head. The height of the contact measuring head can be adjusted according to the standard thickness of the aluminum material, providing operators with an adjustment reference.
[0023] 4. The setting of the limit cylinder and limit plate ensures the stable positioning of the aluminum material during the measurement process, preventing the aluminum material from shifting or shaking, thereby ensuring the reliability of the measurement results. At the same time, the gap between the limit plate and the rubber roller also takes into account the movement requirements of the aluminum material when moving left and right.

[0037] Example 1
[0038] like Figure 1-4 As shown, this utility model provides a technical solution: an aluminum material thickness detection device, including a detection platform 1 and a contact measuring head 2. The contact measuring head 2 is specifically selected as a dial indicator. The contact measuring head 2 is installed on a lifting mechanism 3. The lifting mechanism 3 can drive the contact measuring head 2 to move up and down to adapt to the detection requirements of aluminum materials of different thicknesses. A front and rear adjustment cylinder 4 is further installed on the lifting mechanism 3. The contact measuring head 2 is installed at the output end of the front and rear adjustment cylinder 4, and the output end faces the detection platform 1, so that the contact measuring head 2 can be finely adjusted in the front and rear direction to adjust the front and rear measurement points.
[0039] On one side of the front and rear adjustment cylinder 4, a height measuring mechanism 5 is installed. The height measuring mechanism 5 includes a connecting sleeve 51, which is fitted onto a vertical scale 52. The scale value on the scale 52 increases upward from the end of the detection platform 1. This design can intuitively display the current height position of the contact measuring head 2 and provide the operator with a reference for adjusting the height of the contact measuring head 2.
[0040] The top of the testing table 1 has a measuring groove 11 along its length for placing the aluminum material to be tested. Limiting cylinders 12 are provided on both sides of the measuring groove 11 away from the operating end of the testing table 1. The output end of the limiting cylinder 12 is provided with a limiting plate 13 along the length of the measuring groove 11. When the aluminum material is placed into the measuring groove 11, the limiting cylinder 12 can drive the limiting plate 13 to move, restricting the aluminum material (which can move left and right) within the measuring groove 11, preventing it from shifting or shaking significantly during the measurement process.
[0041] Example 2
[0042] like Figure 1-4As shown, the lifting mechanism 3 is a screw lifting mechanism 3, which has the characteristics of smooth transmission and high precision. The front and rear adjusting cylinders 4 are mounted on the screw nut of the screw lifting mechanism 3 through the fixed seat 41. This design can ensure the synchronous movement between the front and rear adjusting cylinders 4 and the lifting mechanism 3.
[0043] The contact measuring head 2 is mounted on the detection seat 21, and then mounted on the output end of the front and rear adjusting cylinder 4 through the detection seat 21. This design makes the installation of the contact measuring head 2 more stable, and also facilitates subsequent maintenance and replacement.
[0044] The connecting sleeve 51 is connected to the side of the fixed base 41 via the connecting rod 511, and moves up and down synchronously with the fixed base 41. The connecting sleeve 51 is slidably connected to the scale 52, and its bottom surface is horizontal to the detection head of the contact measuring head 2. In this way, when the lifting mechanism 3 drives the contact measuring head 2 to rise and fall, the connecting sleeve 51 will also rise and fall on the scale 52 at the same time, thus intuitively displaying the height position of the contact measuring head 2.
[0045] The scale 52 is installed in the sub-groove 111 which is connected to the measuring groove 11. The distance from the starting point of the scale of the scale 52 to the connecting sleeve 51 is the same as the distance between the detection head of the contact measuring head 2 and the measuring groove 11. This design ensures the accuracy of height measurement, so that the operator can directly obtain the height difference between the contact measuring head 2 and the measuring groove 11 by observing the position of the connecting sleeve 51 on the scale 52.
[0046] Rubber rollers 112 are provided at both ends of the top of the measuring groove 11 and at the center corresponding to the contact measuring head 2. These rubber rollers 112 are rotatably connected to the grooves opened in the measuring groove 11, and their protrusion height is no more than 0.5cm. The setting of rubber rollers 112 not only reduces the friction between the aluminum material and the measuring groove 11, but also assists in the lateral displacement of the aluminum material for thickness detection.
[0047] A certain gap is left between the limiting plate 13 and the rubber roller 112. The size of this gap is adjusted according to the width of the aluminum material. When the limiting cylinder 12 extends and retracts, it will drive the limiting plate 13 to move closer to or further away from the other side of the measuring groove 11, thereby firmly clamping the aluminum material in the measuring groove 11. At the same time, in order to take into account the left and right displacement requirements of the aluminum material during measurement, an active gap of no more than 1cm is reserved between the limiting plate 13 and the other side of the measuring groove 11.
[0048] In the workflow of this utility model, when using an aluminum material thickness detection device, the aluminum material to be tested is first placed stably in the measuring groove 11. Then, by controlling the extension and retraction of the limiting cylinder 12, the limiting plate 13 limits the aluminum material within the measuring groove 11. Next, according to the thickness of the aluminum material and the testing requirements, the lifting mechanism 3 and the front and rear adjusting cylinder 4 are adjusted so that the contact measuring head 2 is accurately positioned at the testing point of the aluminum material. At this time, the operator can directly determine the height position of the contact measuring head 2 by observing the position of the connecting sleeve 51 on the scale 52, and then, combined with the reading of the dial indicator, determine the accurate thickness value of the aluminum material at that point. During the testing process, the aluminum material is moved left and right, and the contact measuring head 2 can be adjusted back and forth by the front and rear adjusting cylinder 4. In order to obtain a more comprehensive thickness distribution, the above steps can be repeated to measure at multiple positions on the surface of the aluminum material.
[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
