Specific implementation mode

[0029] Next, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the attached Figures 1-5 , in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] (As Figure 1 shown) The usage method of the adjustable combined gradient arc plate detection template includes the following steps:

[0031] Step S1, pre-connect the adjustable combined gradient arc plate detection template: Use the fastener 3 to pre-connect but not fix the positioning hole 101 of the transition section template 1 and the guide adjustment groove 201 of the arc section template 2. That is, ensure the adjustability of the adjustable combined gradient arc plate detection template 5, and the later adjustment and use are convenient, fast, and simple to operate. The fastener 3 is composed of a bolt and a nut. The bolt can be a double-headed bolt.

[0032] Step S2, accurately position and adjust the adjustable combined gradient arc plate detection template and use the strong magnetic adsorption type limit block to restrict and limit to prevent the combined parts from changing positions: Based on the 1:1 paper pattern or ground pattern as a reference, on the platform, slide and adjust the relative position of the transition section template 1 through the guide adjustment groove 201, so that the alignment grooves 104 of the transition section template 1 respectively correspond to the vertical baseline, arc start and end lines of the paper pattern or ground pattern, and then use the strong magnetic adsorption type limit block 4 to fix the two ends of the adjusted transition section template 1 and the arc section template 2 respectively, so as to restrict and limit through the strong magnetic adsorption type limit block 4 to prevent the transition section template 1 and the arc section template 2 from changing positions again.

[0033] That is, the adjustable combined gradient arc plate detection template is adjusted adaptively according to the 1:1 paper pattern or ground pattern, realizing the general adjustment of different templates, achieving multi-purpose use of one object, and reducing the production cost of the detection template.

[0034] Step S3, use the fastener to fix the adjustable combined gradient arc plate detection template: Use the fastener 3 to lock the positions of the transition section template 1 and the arc section template 2 after restricting and limiting with the strong magnetic adsorption type limit block 4 to obtain the adjusted adjustable combined gradient arc plate detection template 5.

[0035] That is, four strong magnetic adsorption type limit blocks 4 are adopted, and every two strong magnetic adsorption type limit blocks 4 are used to respectively abut against the positions on the side surfaces of the end plate thicknesses at both ends of the transition section template 1 and the arc section template 2, so as to restrict and position the adjusted positions of the transition section template 1 and the arc section template 2.

[0036] When the strong magnetic adsorption type limit block 4 is used, by screwing the rotating handle of the strong magnetic adsorption type limit block 4, the switching between strong magnetism and weak magnetism is realized, which is convenient for the adsorption and fixation in this step or the quick disassembly in the later stage (combined with Figure 5 ).

[0037] Step S4: Use the adjustable combined variable arc plate detection template that has been combined and fixed to detect: Coarsely position the adjusted, combined and fixed adjustable combined variable arc plate detection template 5 inside the wall plate to be detected, and at the position corresponding to the arc cross-section of the wall plate to be detected. Use a digital display angle gauge to adjust the included angle between the adjustable combined variable arc plate detection template 5 and the wall plate; then align the adjustable combined variable arc plate detection template 5 with the baseline and the arc start and end lines of the wall plate to be detected through the wire groove 104, so as to accurately position the adjustable combined variable arc plate detection template 5; then visually detect the close-fitting condition between the adjustable combined variable arc plate detection template 5 and the inner surface of the wall plate to be detected, so as to determine the linear accuracy of the bending of the wall plate to be detected. The visual detection method is intuitive, efficient, reliable and simple.

[0038] (As shown in Figure 2 、 Figure 3 、 Figure 4 ) It also includes an adjustable combined variable arc plate detection template.

[0039] The adjustable combined variable arc plate detection template 5 is composed of an arc section template 2, transition section templates 1 respectively installed at both ends of the arc section template 2, fasteners 3 and strong magnetic adsorption type limit blocks 4. The adjustable combined variable arc plate detection template 5 has a streamlined component number, a simple structure, is convenient to manufacture, and is economical and practical.

[0040] The arc section template 2 is made of a plate, and the material is easy to obtain. And an arc-shaped guiding and adjusting groove 201 is formed in the middle of the plate body; the arc-shaped guiding and adjusting groove 201 is used to adjust the radian formed by the transition section template 1 and the arc section template 2.

[0041] In the above-mentioned embodiment, further: The guiding and adjusting groove 201 has two spaced and parallel ones to improve the connection reliability.

[0042] One end of the transition section template 1 is an arc section 102 that coincides with the arc section template 2; the other end of the transition section template 1 is a straight section 103. The transition section template 1 is also made of a plate, and the material is easy to obtain.

[0043] The arc segment 102 is used for combined connection and detection, and the straight segment 103 is used for convenient holding adjustment and installation alignment.

[0044] Upper and lower wire alignment grooves 104 are provided between the arc segment 102 and the straight segment 103. The wire alignment grooves 104 can quickly and accurately position the tooling in place according to the reference line.

[0045] In the above embodiment, further: the wire alignment groove 104 is a triangular notch structure, and the bottom shape of the groove formed by the triangular notch is the apex angle of the triangle. The connection line of the upper and lower triangular apex vertices forms the alignment reference of the adjustable combined gradient arc plate detection template 5, so as to quickly and accurately position the tooling in place according to the alignment reference.

[0046] The arc segment 102 is provided with positioning holes 101; the positioning holes 101 are used to lock the adjusted radian of the transition segment template 1 and the arc segment template 2 by using the fastener 3.

[0047] The positioning holes 101 formed on the arc segment 102 are four. Every two of the four positioning holes 101 are distributed up and down as a group, and the height positions of every two of the four positioning holes 101 on the arc segment 102 are the same as the height positions of the two guiding adjustment grooves 201 on the arc segment template 2 to ensure the detection accuracy.

[0048] Further: the aperture of each positioning hole 101 is the same, and the aperture of the positioning hole 101 is 1 mm larger than the outer diameter of the bolt of the fastener 3, which is also used to ensure the detection accuracy.

[0049] On this basis, the strong magnetic adsorption type limit block 4 is used to limit both ends of the adjusted transition segment template 1 and the arc segment template 2.

[0050] (As Figure 5 shown) In the above embodiment, further: the strong magnetic adsorption type limit block 4 is a magnetic seat with a cubic structure. The magnetic seat has a rotatable handle.

[0051] It should be noted that: the magnetic seat is a prior art. The left and right vertical side walls of the magnetic seat body are used to fit the side surfaces in the thickness direction of the end plates of the transition segment template 1 and the arc segment template 2 to restrict the adjusted limit transition segment template 1 and the arc segment template 2, so as to keep the position of the combined component unchanged before the fastener is tightened; after the fastener is tightened, it is convenient to remove the magnetic seat.

[0052] The working principle of the present invention is as follows: For the adjustable combined gradually changing circular arc plate detection template 5 of the present invention, after determining the arc length dimension of the cross-section arc of the wall plate to be detected, the positioning hole 101 of the transition section template 1 and the guiding adjustment groove 201 of the circular arc section template 2 are connected by the fastener 3 and the arc length of its detection area is adjusted; after the adjustment is in place, the degrees of freedom are jointly restricted by the fastener 3 and the strong magnetic adsorption type limit block 4 to obtain the adjustable combined gradually changing circular arc plate detection template 5 for detecting the wall plate to be measured. It is applicable to detect the arc wall plate to be detected with the adjusted adjustable combined gradually changing circular arc plate detection template 5.

[0053] It can be seen that the present invention avoids the adverse factors such as large errors, poor precision, and inability to cover the entire cross-section in the traditional manual detection method; at the same time, it ensures the circular arc linear quality of the wall plate and the assembly precision of the subsequent stiffeners; it also saves a large amount of manufacturing costs for detection templates with different arc lengths and reduces the labor intensity.

[0054] The adjustable combined gradually changing circular arc plate detection template 5 of the present invention has a simple structure, is convenient to install, has a simple operation, is easy to implement, and has strong applicability; it can control the precision dimensions of the circular arc wall plate of the steel tower within the standard range, which is beneficial to the precision control of the steel tower segments and the improvement of the overall landscape.

[0055] It can be found through the above description that the present invention uses the combined circular arc surface detection template tooling. In the case of the same radius, it can detect the circular arc cross-section dimensions and linear shapes of different arc lengths more comprehensively and accurately through adjustment, achieving better effects, effectively controlling the linear quality of the wall plate, and ensuring the precision requirements.

[0056] In summary, the present invention avoids the disadvantages of the traditional manual detection method such as large errors, poor precision, and inability to cover the entire cross-section, and reduces the difficulty of detecting complex products. It is relatively convenient for installation, use and disassembly, safe and reliable, easy to implement, and has strong applicability. It reduces the production of a large number of templates with different specifications and reduces the expenditure on tooling. It effectively guarantees the linear dimensions of the circular arc wall plate of the steel tower, greatly improves the precision control of the steel tower segments, and meets the requirements of the steel structure for the landscape.

[0057] Each embodiment in this specification is described in a related manner. For the same or similar parts among the embodiments, reference can be made to each other. The key points of each embodiment are the differences from other embodiments.

[0058] The above description is only for the preferred embodiments of the present invention and is not intended to limit the protection scope of the present invention.
