Description

Technical Field

[0001] The invention relates to the technical field of section steel measurement, in particular to an adjustable flange slope clamping plate and a use method thereof. Background Art

[0002] Chinese patent publication number CN221077532U discloses a steel flange pitch gauge. The gauge consists of a horizontal section, a vertical section, and a right-angled triangle. The upper portion of the vertical section connects to the right end of the horizontal section, while the bottom of the vertical section connects to the upper right end of the right-angled triangle. The upper and left sides of the right-angled triangle form a right angle, and the lower right side serves as a hypotenuse. The bottom surface of the horizontal section serves as the measuring surface for the gauge, while the left end surface of the right-angled triangle serves as a reference surface. This gauge is used to measure the pitch of H- or T-beam flanges and features a simple structure, reliable measurement results, and easy operation.

[0003] However, there are two problems in this patent:

[0004] 1. Lack of Versatility: According to the GB / T11263 standard for "Hot-rolled H-shaped Steel and Some T-shaped Steel," international and domestic steel production is diverse, with hundreds of specifications ranging from 95 mm to 1008 mm in various heights. Existing pallets are only suitable for measuring the inclination of steel flanges of fixed specifications, requiring frequent tool changes in practice. A single pallet cannot cover a wide range of specifications. This inability to adapt to varying component sizes results in poor reusability. Testing the inclination of steel flanges of various sizes requires measuring equipment of varying sizes, requiring a wide variety of gauges, increasing production costs and reducing work efficiency.

[0005] 2. Poor adaptability: In view of the unique structure of steel sections - the rolled connection between the flange and the web is a transition of arc, it is difficult for ordinary squares to fit the surface of the special-shaped flange, and it is impossible to directly measure the slope value of the web and flange of the steel section. Summary of the Invention

[0006] The purpose of the present invention is to provide an adjustable flange inclination clamp and a method of use. Through the adjustable structure, precise benchmark design and standardized operation method, efficient, accurate and stable steel flange inclination detection is achieved, solving the problems raised in the above-mentioned background technology.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] An adjustable flange slope clamping plate includes a main scale and a sliding block. The main scale includes a slide scale and a fixed block. The fixed block is fixed to the side port of the slide scale. The slide scale and the fixed block are perpendicular to each other and form a right-angle L-shaped structure. The slide scale is provided with a T-groove. The T-groove is a double-sided open structure. The outer surface of the T-groove is provided with a scale.

[0009] The sliding block is a hollow rectangular block, which is inserted into the T-shaped groove and slidably connected with the sliding groove ruler. A fastening device is provided on the side of the sliding block facing the T-shaped groove;

[0010] The side of the sliding block away from the T-shaped groove is the reference surface, and the side of the fixed block facing the sliding block is the measuring surface. The reference surface and the measuring surface are perpendicular to each other.

[0011] Preferably, the T-shaped groove consists of a sliding groove and a mounting groove, and the width of the sliding groove is the same as the thickness of the sliding block.

[0012] Preferably, the fastening device includes two fastening bolts, and two threaded holes are provided on a side of the sliding block opposite to the reference surface. The fastening bolts pass through the mounting slot and are threadably engaged with the threaded holes.

[0013] Preferably, the slide ruler, fixed stop block and sliding block are made of carbon tool steel or stainless steel with a hardness range of 53HRC to 56HRC or 561HV to 620HV.

[0014] Preferably, the length of the measuring surface is greater than half the length of the maximum specification steel flange.

[0015] Preferably, the end of the slide ruler away from the fixed stop block is an open port.

[0016] A method for using an adjustable flange slope clamp is implemented based on the adjustable flange slope clamp and includes the following steps:

[0017] Step 1: Make the measuring surface fit the outer surface of the steel flange, and make the fixed block flush with the end surface of the steel flange;

[0018] Step 2: Push the sliding block along the extension direction of the slide ruler, and adjust the sliding block to the target position by observing the scale, so that the reference surface is aligned with the center line of the steel web;

[0019] Step 3: Tighten the fixing bolts to lock the sliding block so that the sliding block is not loose after being locked;

[0020] Step 4: Insert the feeler gauge into the maximum gap between the measuring surface and the steel flange to determine whether the inclination of the steel flange is qualified.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention realizes stepless adjustment of the sliding block along the slide ruler through the cooperation between the T-groove of the slide ruler and the sliding block, covering the detection needs of steel sections of different specifications, avoiding frequent replacement of special clamping plates, and significantly improving detection efficiency; the outer surface of the T-groove is marked with a scale, which directly corresponds to the height of the steel web. No manual calculation is required during operation, and the sliding block can be quickly adjusted to the target position, simplifying the operation process.

[0023] 2. The present invention uses a feeler gauge to directly measure the maximum gap between the measuring surface and the steel flange, quickly determining whether the inclination is qualified, avoiding subjective judgment, and improving detection efficiency by more than 30%. By measuring the bevel angle from the outer wall of the flange, it avoids the traditional technology of measuring from the connection between the flange and the web, which is prone to cause a lack of fit, greatly improving measurement convenience.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] In order to solve the problem of poor versatility and adaptability of existing measurement card boards, please refer to Figure 1-6 , this embodiment provides the following technical solutions:

[0033] An adjustable flange slope clamp includes a main ruler 1 and a sliding block 2. The main ruler 1 includes a slide ruler 105 and a fixed block 102. The fixed block 102 is fixed to the side port of the slide ruler 105. The slide ruler 105 and the fixed block 102 are perpendicular to each other and form a right-angle L-shaped structure.

[0034] The slide ruler 105 is provided with a T-shaped groove 103, which is a double-sided opening structure. The T-shaped groove 103 is composed of a sliding groove 106 and an installation groove 107. The width of the sliding groove 106 is the same as the thickness of the sliding block 2. The sliding block 2 can move in the sliding groove 106 to achieve free displacement with the slide ruler 105 to cover the detection needs of steel sections of different specifications and avoid frequent replacement of detection accessories.

[0035] The outer surface of the T-shaped groove 103 is provided with a scale 104 for positioning the sliding block 2 to the position corresponding to the center line of the steel web 4, directly corresponding to the height of steel webs 4 of different specifications, avoiding manual calculation and adjustment of the position, and improving detection efficiency.

[0036] The vertical design of the fixed stop block 102 and the T-shaped groove 103 ensures the geometric accuracy of the measurement benchmark and ensures that the test results meet the requirements of the national standard GB / T 11263.

[0037] The sliding block 2 is a hollow rectangular block. The sliding block 2 is inserted into the T-shaped groove 103 and is slidably connected to the sliding groove ruler 105. A fastening device is provided on the side of the sliding block 2 facing the T-shaped groove 103.

[0038] The side of the sliding block 2 away from the T-shaped groove 103 is the reference surface 201 , and the side of the fixed stopper 102 facing the sliding block 2 is the measuring surface 101 . The reference surface 201 and the measuring surface 101 are perpendicular to each other.

[0039] The fastening device includes two fastening bolts 203. Two threaded holes 202 are provided on the side of the sliding block 2 opposite to the reference surface 201. The fastening bolts 203 pass through the mounting groove 107 and are threadedly engaged with the threaded holes 202 to quickly fix the sliding block 2, prevent the sliding block 2 from being displaced due to external force during measurement, and ensure detection stability.

[0040] The material of the slide ruler 105, the fixed stop block 102 and the sliding block 2 is carbon tool steel or stainless steel with a hardness range of 53HRC to 56HRC or 561HV to 620HV, which can resist the wear of the steel surface and extend the service life of the device.

[0041] The length of the measuring surface 101 is greater than half the length of the maximum specification steel flange 3. After the reference surface 201 is fitted with the steel web 4, the measuring surface 101 is fitted with the steel flange 3. The steel flange 3 does not fit into the sliding groove 106.

[0042] One end of the slide ruler 105 away from the fixed stop block 102 is an open port, allowing the sliding block 2 to be installed into the slide ruler 105 through the open port, thereby simplifying the assembly process.

[0043] A method for using an adjustable flange slope clamp is implemented based on the adjustable flange slope clamp and includes the following steps:

[0044] Step 1: Make the measuring surface 101 fit the outer surface of the steel flange 3, and make the fixed stopper 102 flush with the end surface of the steel flange 3;

[0045] Step 2: Push the sliding block 2 along the extension direction of the sliding groove ruler 105, and adjust the sliding block 2 to the target position by observing the scale 104 so that the reference surface 201 is aligned with the center line of the steel web 4;

[0046] Step 3: Tighten the fastening bolt 203 to lock the sliding block 2 so that the sliding block 2 is not loose after being locked;

[0047] Step 4: Insert the feeler gauge 5 into the maximum gap between the measuring surface 101 and the steel flange 3 to determine whether the inclination of the steel flange 3 is qualified. If it is qualified, the product is unqualified. This method directly quantifies the inclination deviation of the steel flange 3, simplifies the determination process, and improves the detection efficiency.

[0048] Working principle: make the measuring surface 101 fit the outer surface of the steel flange 3, and the fixed block 102 is flush with the end face of the steel flange 3; push the sliding block 2 along the extension direction of the slide ruler 105, and adjust the sliding block 2 to the target position by observing the scale 104, so that the reference surface 201 is aligned with the center line of the steel web 4; tighten the fastening bolt 203 to lock the sliding block 2, so that the sliding block 2 is not loose after being locked; insert the feeler gauge 5 into the maximum gap between the measuring surface 101 and the steel flange 3 to determine whether the inclination of the steel flange 3 is qualified. If it is qualified, the product is unqualified. This method can directly quantify the inclination deviation of the steel flange 3, simplify the determination process, and improve the detection efficiency.
