Description

Technical Field

[0001] This utility model relates to the field of coil testing technology, specifically to a device for measuring the dimensional change rate of coil heat treatment. Background Technology

[0002] In the field of building materials, waterproof membranes, as an important flexible building material, are widely used in building walls, roofs, tunnels, highways, and landfills. The dimensional change rate test of waterproof membranes after heat treatment is an important test to evaluate the adaptability of waterproof membranes to the expansion, contraction, or cracking deformation of the substrate as temperature changes. Its dimensional change rate has become an important indicator for measuring its quality stability.

[0003] In traditional methods, the measurement of the dimensional change rate of rolled materials mainly relies on manual measurement using simple tools such as calipers. This method has the following drawbacks:

[0004] 1. Low efficiency: When multiple batches of waterproof membrane samples need to be tested for batch heat treatment, the speed of dimensional measurement is slow.

[0005] 2. Since rolled materials often curl or deform after heat treatment, it is difficult to ensure that the sample is in a straight state during manual measurement, thus making it difficult to guarantee the accuracy of the measurement.

[0006] Therefore, how to solve the shortcomings of the existing technology caused by manual measurement has become the subject of this utility model. Utility Model Content

[0007] The purpose of this invention is to provide a device for measuring the dimensional change rate of rolled materials during heat treatment.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] Equipment for measuring the dimensional change rate of heat-treated coil materials, including:

[0010] The processing table serves as a supporting component;

[0011] The flattening assembly includes a drive unit disposed on the processing table, a first flattening member and a second flattening member connected to the drive unit and used for flattening the sample to be tested; the first flattening member and the second flattening member can be driven by the drive unit to move vertically; there is an adjustment space between the first flattening member and the second flattening member; the first flattening member is provided with an alignment hole;

[0012] The measuring component, which serves as an active part for measuring the size of the portion of the sample to be tested facing the alignment hole, includes a dimensional measuring device movably mounted on the processing table.

[0013] In the above scheme, the flattening assembly flattens the sample to be measured before measurement to avoid inaccurate measurement results due to sample bending. Before flattening, the first and second flattening components have gaps with the processing table, and the size of the gaps can be adjusted. During the preparation stage, the sample to be measured is inserted into the gap, with a portion of the sample aligned with the alignment hole. Then, the first and second flattening components are driven by the drive component to press down and flatten the sample. During measurement, the dimensional measuring instrument moves between two predetermined positions to measure the size of the portion of the sample aligned with the alignment hole. The measured size is used to determine whether the dimensional change rate of the roll material after heat treatment is within the normal range. Under normal circumstances, measurement can be performed using only the first flattening component. However, considering that the sample may move or become skewed when the first flattening component presses down, potentially reducing accuracy, the use of the second flattening component in conjunction with the first flattening component to press down on the sample avoids this situation. By setting an adjustment space, the position and orientation of the sample to be tested can be adjusted during and after insertion, ensuring that the sample is placed in the predetermined position. The size of the adjustment space can be adjusted according to requirements.

[0014] With the above setup, the actual measurement operation is completed by the measurement component, and the operator only needs to be responsible for the feeding process, which reduces the amount of operation and improves the accuracy of measurement. In addition, even if the sample to be tested has a high degree of curvature, the curvature is low after the sample is inserted into the gap, which facilitates the subsequent flattening of the sample.

[0015] In a further technical solution, the dimension measuring device is movably mounted on the processing table via the support member; the dimension measuring device is provided with a through hole for the support member to pass through.

[0016] The dimension measuring device has a through hole, and there is a gap between the support part and the processing table, with the through hole passing through this part of the support part, and the dimension measuring device part is located within the gap.

[0017] Optionally, the length extension direction of the support member is parallel to the length extension direction of the processing table, and the support member serves to support the dimension measuring device and limit the movement path of the dimension measuring device.

[0018] A further technical solution is that the support includes two first support rods placed at symmetrical ends on the top of the processing table, and a second support rod whose ends are detachably connected to the two first support rods respectively;

[0019] The dimension measuring device is movably sleeved on the outside of the second support rod.

[0020] The second support rod can be separated from the first support rod, and the dimension measuring device can be separated from the second support rod, which facilitates the installation and disassembly of the dimension measuring device.

[0021] In a further technical solution, either the first support rod or the second support rod is provided with a slot, and the other is provided with a block corresponding to the slot.

[0022] The first support rod and the second support rod can be detachably connected by the engagement of the slot and the block, which is simple and convenient.

[0023] In a further technical solution, the size measuring device includes a display screen for displaying measurement results.

[0024] The dimensional measuring device measures the dimensions of the portion of the sample directly opposite the alignment hole. The measurement results are then displayed on the screen, and the operator records the results for further evaluation.

[0025] In a further technical solution, the size measuring device also includes a zeroing button for zeroing the measurement result.

[0026] by Figure 4 The following example illustrates the process for testing a sample: In some cases, the surface of the sample is marked with crosshairs, with the center of the intersection of the crosshairs designated as the second detection point. The first and third detection points are respectively located at the two ends of the portion of the sample facing the alignment hole. During testing, the distance between the first and second detection points is measured first, followed by the distance between the second and third detection points. A zeroing button allows for zeroing after the distance between the first and second detection points is measured and recorded, enabling direct measurement of the distance between the second and third detection points later, avoiding calculations. Performing two measurements allows for separate testing of different areas of the sample, improving accuracy.

[0027] In a further technical solution, a placement groove is provided in the middle of the processing table; the driving component is placed in the placement groove.

[0028] The drive unit can be placed above the processing table, but compared to this arrangement, the arrangement in this embodiment can improve the utilization rate of the processing table, reduce the space occupied by this application, and improve the aesthetics.

[0029] In a further technical solution, the driving component includes a driving cylinder and a connecting component connected together; the driving cylinder is placed in the placement groove; the connecting component passes through the processing table and is connected to the first flattening component and the second flattening component.

[0030] The terms "first," "second," etc., used in this article do not specifically refer to order or sequence, nor are they intended to limit this case; they are merely used to distinguish components or operations described using the same technical terms.

[0031] The terms "connection" or "positioning" as used in this article can refer to two or more components or devices making direct physical contact with each other, or making indirect physical contact with each other, or to two or more components or devices operating or moving with each other.

[0032] The terms “include,” “including,” and “have” used in this article are all open-ended, meaning they include but are not limited to.

[0033] Unless otherwise specified, the terms used herein generally have their ordinary meaning in the context of the art, the subject matter, and the specific context. Certain terms used to describe this case will be discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the case.

[0034] The terms “front,” “back,” “up,” “down,” “left,” and “right” used in this article are directional terms. In this case, they are only used to describe the positional relationship between the structures and are not intended to limit the specific direction of the protection scheme or its actual implementation.

[0035] The working principle and advantages of this utility model are as follows: Before measurement, the flattening component flattens the sample to be measured to avoid the measurement results being unreliable due to the bending of the sample; before flattening, the first flattening component and the second flattening component have a gap with the processing table; in the preparation stage, the sample to be measured is inserted into the gap, with part of the sample aligned with the alignment hole, and then the first flattening component and the second flattening component are driven by the driving component to press down to flatten the sample; during measurement, the dimension measuring device moves between two predetermined positions to measure the dimension of the part of the sample to be measured that is aligned with the alignment hole, and the measured dimension determines whether the dimensional change rate of the roll material after heat treatment is within the normal range. With the above setup, the actual measurement operation is completed by the measurement component, and the operator only needs to be responsible for processes such as feeding. This reduces the amount of operation while improving the accuracy and efficiency of measurement. In addition, even if the sample to be tested has a high degree of curvature, the curvature is low after the sample is inserted into the gap, which facilitates the subsequent flattening of the sample. The measurement accuracy of the sample to be tested that is completely flattened by the flattening component is guaranteed.

[0036] Under normal circumstances, measurement can be performed by setting only the first flattening component. However, considering that the sample may move or tilt when the first flattening component presses down on it, which may reduce the accuracy, the above situation can be avoided by setting a second flattening component in conjunction with the first flattening component to press down on the sample.

[0037] By setting an adjustment space, the position and orientation of the sample to be tested can be adjusted during and after insertion, ensuring that the sample is placed in the predetermined position. Attached Figure Description

[0043] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0044] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0046] See Figures 1-4 Equipment for measuring the dimensional change rate of heat-treated coil materials, including:

[0047] Processing table 1 serves as a supporting component;

[0048] The flattening assembly 2 includes a drive member 21 disposed on the processing table 1, a first flattening member 22 and a second flattening member 23 connected to the drive member 21 and used to flatten the sample 6 to be tested; the first flattening member 22 and the second flattening member 23 can be driven by the drive member 21 to move vertically; there is an adjustment space 3 between the first flattening member 22 and the second flattening member 23; the first flattening member 22 is provided with an alignment hole 221;

[0049] The measuring component 4, which serves as a part for measuring the size of the portion of the sample 6 to be tested that faces the alignment hole 221, includes a size measuring device 41 and a point vision amplifier 42 that are movable parallel to the alignment hole 221 on the processing table 1; the moving path of the point vision amplifier 42 is located above the alignment hole 221.

[0050] The processing table 1 is a basic supporting structure that provides support for other structures. The specific shape, size, and other settings of the processing table 1 are not limited here.

[0051] Before measurement, the flattening assembly 2 flattens the sample 6 to be tested to avoid inaccurate measurement results due to bending of the sample 6. Before flattening, the first flattening component 22 and the second flattening component 23 have gaps with the processing table 1, and the size of the gaps can be adjusted (when the point vision amplifier 42 is set, the adjustment range of the gaps is affected by the position of the point vision amplifier 42). In the preparation stage, the sample 6 to be tested is inserted into the gaps, with part of the sample 6 facing the alignment hole 221. Then, the first flattening component 22 and the second flattening component 23 are driven by the driving component 21 to press down and flatten the sample 6 to be tested. During measurement, the dimension measuring device 41 moves between two predetermined positions to measure the size of the part of the sample 6 facing the alignment hole 221. The measured size is used to determine whether the dimensional change rate of the roll material after heat treatment is within the normal range.

[0052] Optionally, the size measuring device 41 can be a laser rangefinder, displacement sensor, optical measurement system, etc., depending on the material, shape, size and measurement accuracy requirements of the sample 6 to be measured.

[0053] The dimensional change rate of the test sample 6 is obtained by comparing the measured dimensions with the reference dimensions and calculating the percentage difference. The calculated dimensional change rate is then compared with the expected or standard dimensional change range. If the change rate is within the normal range, it indicates that the heat treatment effect of the test sample 6 is good. If it exceeds the normal range, it may be necessary to adjust the heat treatment process or further analyze the cause.

[0054] It should be noted that, under normal circumstances, measurement can be performed by setting only the first flattening component 22. However, considering that the sample 6 may move or tilt when the first flattening component 22 presses down on it, which may reduce the accuracy, the above situation can be avoided by setting the second flattening component 23 in conjunction with the first flattening component 22 to press down on the sample 6.

[0055] It should also be noted that by setting the adjustment space 3, the position and orientation of the sample 6 to be tested can be adjusted during and after insertion, ensuring that the sample 6 is placed in the predetermined position. The size of the adjustment space 3 can be adjusted as needed.

[0056] With the above settings, the actual measurement operation is completed by the measurement component 4, and the operator only needs to be responsible for processes such as feeding materials, which reduces the amount of operation and improves the accuracy and efficiency of measurement.

[0057] It should be emphasized that this application can measure test samples 6 of different sizes; in addition, even if the test sample 6 has a high degree of curvature, the degree of curvature is low after the test sample 6 is inserted into the gap, which facilitates the subsequent complete flattening of the test sample 6.

[0058] The point-to-point visual amplifier 42 (which can be configured as a magnifying glass) is used to magnify the observation of the sample to be tested (such as magnifying the observation of the following detection points), thereby improving the measurement accuracy of the size measuring instrument 41.

[0059] The setting of the point visual amplifier 42 will limit the vertical movement range of the first flattening member 22 and the second flattening member 23. The setting of the point visual amplifier 42 is adapted to the adjustment space 3.

[0060] See Figure 1 In this embodiment, the dimension measuring device 41 is movably mounted on the processing table 1 via the support member 5; the dimension measuring device 41 is provided with a through hole for the support member 5 to pass through.

[0061] The dimension measuring device 41 is not directly connected to the machining table 1, but is indirectly connected to the machining table 1 through the intermediate structure of the support member 5.

[0062] Support 5 is set on processing table 1. Taking this as an example, it can be fixed by welding or detachable by threaded connection, depending on actual needs.

[0063] The dimension measuring device 41 has a through hole (not marked in the figure), and there is a gap between the part of the support member 5 (the second support rod 52 in the following description) and the processing table 1, and this part of the support member 5 has a through hole, and part of the dimension measuring device 41 is located in the gap.

[0064] Optionally, the length extension direction of the support member 5 is parallel to the length extension direction of the processing table 1, and the support member 5 serves to support the dimension measuring device 41 and limit the movement path of the dimension measuring device 41.

[0065] See Figure 1 , Figure 2In this embodiment, the support member 5 includes two first support rods 51 placed at the two symmetrical ends of the top of the processing table 1, and a second support rod 52 whose ends are respectively detachably connected to the two first support rods 51.

[0066] The dimension measuring device 41 is movably sleeved on the outside of the second support rod 52.

[0067] The two first support rods 51 cooperate to support and raise the second support rod 52, thereby forming the aforementioned space.

[0068] Optionally, the second support rod 52 is provided with scale values. In this case, the second support rod 52 can be regarded as a ruler, which can be used by the operator for reference.

[0069] The second support rod 52 can be separated from the first support rod 51, and the dimension measuring device 41 can be separated from the second support rod 52, which facilitates the installation and disassembly of the dimension measuring device 41.

[0070] In this embodiment, either the first support rod 51 or the second support rod 52 is provided with a slot, and the other is provided with a block corresponding to the slot.

[0071] This embodiment provides a specific method for detachably connecting the first support rod 51 and the second support rod 52, which is achieved by engaging a slot (not shown in the figure) and a block (not shown in the figure). The structure is simple, convenient and quick.

[0072] It should be noted that when using the method proposed in this embodiment, setting two first support rods 51 can improve the stability of the second support rod 52. When using threaded connections or other methods, only a single first support rod 51 can be used.

[0073] See Figure 1 , Figure 2 In this embodiment, the size measuring device 41 includes a display screen 411 for displaying measurement results.

[0074] The dimension measuring device 41 measures the dimension of the part of the sample 6 facing the alignment hole 221. The measurement result is transmitted to the display screen 411 for display. Then the operator records the measurement result for judgment.

[0075] The display screen 411 is existing technology, and its display principle is well known to those skilled in the art, so it will not be explained in detail here.

[0076] See Figure 1 , Figure 2 In this embodiment, the size measuring device 41 further includes a zeroing button 412 for zeroing the measurement result to display the zero position.

[0077] by Figure 4The following example illustrates the test sample: In some cases, the surface of the test sample is marked with cross lines (which can be erased). The center of the intersection of the cross lines is set as the second detection point 62. The two ends of the part of the test sample 6 facing the alignment hole 221 are respectively set as the first detection point 61 and the third detection point 63. During the test, the distance between the first detection point 61 and the second detection point 62 is measured first, and then the distance between the second detection point 62 and the third detection point 63 is measured. By setting the zeroing button 412, after the distance between the first detection point 61 and the second detection point 62 is detected and recorded, the zeroing process can be performed. Subsequently, the distance between the second detection point 62 and the third detection point 63 can be directly measured, avoiding calculation.

[0078] It should be added that performing two measurements allows for separate testing of different areas of the sample, thus improving the accuracy of the test.

[0079] See Figure 1 In this embodiment, the processing table 1 is provided with a placement groove 11 in the middle; the driving component 21 is placed in the placement groove 11.

[0080] The drive unit 21 can be placed above the processing table 1, but compared with this arrangement, the arrangement in this embodiment can improve the utilization rate of the processing table 1, reduce the space occupied by this application, and improve the aesthetics.

[0081] In this embodiment, the driving component 21 includes a driving cylinder and a connecting component connected together; the driving cylinder is placed in the placement groove 11; the connecting component passes through the processing table 1 and is connected to the first flattening component 22 and the second flattening component 23.

[0082] This embodiment proposes a specific configuration for the drive component 21. The drive cylinder (not marked in the figure) is placed entirely within the placement groove 11, and its piston rod can pass through the placement groove 11. The connecting component (not shown in the figure) needs to be connected to the first pressing component 22 and the second pressing component 23. Therefore, a processing table 1 needs to be installed. The installation is a conventional configuration. The processing table 1 needs to be provided with corresponding through holes. This configuration is well known to those skilled in the art and will not be described in detail here.

[0083] In this embodiment, four driving components 21 are provided to improve the stability during the driving process; two of the driving components 21 are arranged below both ends of the first flattening component 22, and the other two driving components 21 are arranged below both ends of the second flattening component 23.

[0084] In this embodiment, the dimension measuring device 41 is an electronic vernier caliper, which includes a scale and a moving head. The point vision amplifier 42 is located on the moving head, and the scale is located on the processing table 1. The scale can replace the position of the second support rod 52 mentioned above.

[0085] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
