Description

Technical Field

[0001] The utility model relates to the technical field of billet measuring equipment, in particular to a device for measuring the cross-sectional dimensions of a billet. Background Art

[0002] At present, a square billet is a steel billet with equal width and height in cross section, which is cast by continuous casting of molten steel and is used to produce long profile products such as rails, small H-shaped steel, bars and wires. The outer dimensions of the square billet directly affect the performance and processing performance of the square billet. Therefore, many precision machining industries that use square billets as raw materials have strict requirements on the cross-sectional dimensions of the square billet. There are relatively few professional devices for measuring the cross-sectional dimensions of square billets. Usually, operators use calipers to measure the cross-sectional dimensions of square billets, but the measurement accuracy is relatively poor. In view of this, some companies have successively developed measuring devices or measuring tools for the cross-sectional dimensions of square billets. Although these measuring devices or measuring tools each have certain advantages, they all have certain limitations to a greater or lesser extent, and some have relatively high manufacturing costs and some have relatively low measurement accuracy.

[0003] After searching, it was found that three literature patents are most relevant to the utility model technology, and the specific contents are described as follows:

Although the device can perform non-contact online measurement of the three-dimensional size of a moving square steel billet, the structure of the device is relatively complex. Therefore, the manufacturing cost of the device is relatively high and the operation difficulty is relatively large.

[0005] Patent document CN 202020707208.8 discloses a rectangular ingot cross-section measuring tool, which mainly includes a metal rod, an arc-shaped measuring arm, a fixed axis and a scale. The operation process of the device is relatively simple, so the work efficiency is relatively high, but because the design structure of the device is too simple and does not have an accurate measurement system, the measurement accuracy of the device is relatively low.

[0006] Patent document CN 202320457255.5 discloses a new type of online cross-sectional dimension measuring tool for square billets, which mainly includes a measuring ruler, a positioning frame, a fastener, a movable seat, an indicator rod, a roller, an elastic member, a positioning sleeve, a base, a support column, a guide sleeve, an adjusting rod, a locking member, an adjusting bolt, a spirit level, a support rod and a limit sleeve. The design of the device is relatively ingenious, and it can also perform online measurement of the cross-sectional dimensions of high-temperature square billets. However, since the device does not have an accurate measurement system, the measurement accuracy of the device is relatively low. Utility Model Content

[0055] Then, the four fifth bosses 603 of the four fourth brackets 6 are inserted into the four second grooves 506 of the third bracket 5, and then the second groove 506 of another third bracket 5 is opened downward and arranged on the four cushion blocks 9, and the other four fifth bosses 603 of the four fourth brackets 6 are inserted into the four second grooves 506 of the third bracket 5 located above, so that the two third brackets 5 and the four fourth brackets 6 can be assembled;

[0056] At this time, the four sixth through holes 504 of the third bracket 5 located at the top and the four third screw holes 901 of the four cushion blocks 9 are in a centering relationship, and then the other four screws 8 are passed through the four sixth through holes 504 and screwed into the four third screw holes 901, so that another third bracket 5 and the four cushion blocks 9 can be assembled;

In this way, the entire device is assembled and can be put into use.

[0059] The working principle of the device for measuring the cross-sectional dimensions of a square billet provided by the utility model

[0060] like Fig. 20 and Fig.21 As shown, the utility model is based on the scientific concept that averaging multiple measurements can reduce measurement errors. For the convenience of description, the three measuring rods 4 at the top are set as a i (i is a natural number), the three measuring rods 4 at the bottom are set as b i , the three measuring rods 4 on the left are set as c i , set the three measuring rods 4 on the right as e i , the distance between the two fourth bodies 601 of the two fourth brackets 6 arranged at the top and the bottom is set to m, the distance between the two fourth bodies 601 of the two fourth brackets 6 arranged at the left and the right is set to w, and the radius of the first contact segment 401 of the measuring rod 4 is set to r, then the twelve first contact segments 401 of the twelve measuring rods 4 located at the zero scale position just extend out of the four fourth bodies 601 of the four fourth brackets 6, and the extended length is r;

[0061] like Fig.21 As shown, when measuring the cross-sectional dimensions of the billet 14, the twelve measuring rods 4 are all tangent to the billet 14; i , said b i 、the c i and the i The length of the precession is set as △a i , △b i , △c i and △e i , the a i and the b i The measured height of the billet 14 is set as Da i b i , the c i and the i The measured width of the billet 14 is set as Dc i e i; Based on the knowledge that the distance between parallel planes is equal everywhere, we can get the following two equations: r+△a i +Da i b i +r+△b i =m,r+△c i +Dc i e i +r+△e i =w, after sorting, we can get the following two equations: Da i b i =m-2r-△a i -△b i , Dc i e i =w-2r-△c i -△e i ;

[0062] like Fig. 22 and Fig.23 As shown, the utility model is based on three measurements to find the average value, that is, i=3, respectively measuring the height at the left end, middle and right end of the billet 14, and measuring the width at the lower end, middle and upper end of the billet 14; the three measuring rods 4 at the upper position are respectively a 1 、a 2 and a 3 The three measuring rods 4 at the bottom are respectively b 1 , b 2 and b 3 The three measuring rods 4 on the left are c 1 、c 2 and c 3 The three measuring rods 4 on the right are respectively e 1 、e 2 and e 3 The six measuring rods 4 arranged at the top and bottom measure the heights of the three parts, which are Da 1 b 1 、Da 2 b 2 and Da 3 b 3 The six measuring rods 4 arranged on the left and right measure the widths of the three parts, which are Dc 1 e 1 , Dc 2 e 2 and Dc 3 e 3 ; The height of the billet 14 Dab = (Da 1 b 1 +Da 2 b 2 +Da3 b 3 ) / 3, the width Dce of the billet 14 is Dce=(Dc 1 e 1 +Dc 2 e 2 +Dc 3 e 3 ) / 3;

[0063] like Fig. 20 and Fig.21 As shown, the combined use of the twelve scale segments 403 of the twelve measuring rods 4 and the twelve fourth bosses 602 of the four fourth brackets 6 can form twelve screw micrometers, and the measurement accuracy of the twelve screw micrometers can reach 0.01mm. The reasoning process is: since the pitch value of the thread of the measuring rod 4 is 0.5mm, that is, every time the measuring rod 4 rotates one circle, the axial distance moved by the measuring rod 4 in the second screw hole 604 is 0.5mm, and since the side surface of the fourth boss 602 is evenly marked with fifty grid scales along the circumferential direction, therefore, every time the measuring rod 4 rotates one grid scale, the axial distance moved by the measuring rod 4 in the second screw hole 604 is 0.01mm.

[0064] The use process of the device for measuring the cross-sectional dimensions of a square billet provided by the utility model

[0065] Step 1: If Figures 1 to 3 As shown, firstly, the billet 14 is horizontally arranged on the two second bosses 302 of the second bracket 3, and then the twelve measuring rods 4 are rotated to the zero scale position, and then the utility model is sleeved outside the billet 14, and the four wheels 10 are simultaneously arranged in the two first grooves 204 of the two first brackets 2 located on the same side, and then the third bracket vehicle is pushed along the two first grooves 204 to reach the part of the billet 14 that needs to be measured;

[0066] Step 2: If Figure 4 As shown, the sixteen positioning rods 7 are then rotated respectively, and the sixteen second contact segments 701 of the sixteen positioning rods 7 are respectively in contact with the surface of the billet 14, so as to position the billet 14; the twelve measuring rods 4 are then rotated respectively, and the twelve first contact segments 401 of the twelve measuring rods 4 are respectively in contact with the surface of the billet 14, and at this time, the twelve first contact segments 401 of the twelve measuring rods 4 are all in a tangent relationship with the billet 14;

[0067] Step 3: If Figure 21 to Figure 23 As shown, the distances △a of the twelve measuring rods 4 are then read respectively. 1 , △a 2 , △a3 , △b 1 , △b 2 , △b 3 , △c 1 , △c 2 , △c 3 , △e 1 , △e 2 and △e 3 , then measure the distance m between the two fourth bodies 601 of the two fourth brackets 6 arranged at the top and bottom, then measure the distance w between the two fourth bodies 601 of the two fourth brackets 6 arranged at the left and right, and then measure the radius r of the first contact section 401 of the measuring rod 4;

[0068] Step 4: Use formula Da i b i =m-2r-△a i -△b i , calculate the height Da at the left end, middle and right end of the billet 14 1 b 1 、Da 2 b 2 and Da 3 b 3 , through the formula Dab = (Da 1 b 1 +Da 2 b 2 +Da 3 b 3 ) / 3, calculate the height Dab of the billet 14; by the formula Dc i e i =w-2r-△c i -△e i , calculate the width Dc at the lower end, middle and upper end of the billet 14 1 e 1 , Dc 2 e 2 and Dc 3 e 3 , through the formula Dce=(Dc 1 e 1 +Dc 2 e 2 +Dc 3 e 3 ) / 3, and the width Dce of the billet 14 is calculated.

[0069] Supplementary explanation: The device for measuring the cross-sectional dimensions of a square billet provided by the utility model is designed with a symmetrical structure, and the zero scale position refers to the position when the initial scales of the twelve scale segments 403 of the twelve measuring rods 4 and the twelve fourth bosses 602 of the four fourth brackets 6 are all aligned; since the second contact segment 701 and the third contact segment 703 of the positioning rod 7 are both cylindrical structures, this ensures that the sixteen positioning rods 7 and the square billet 14 maintain surface contact.

[0070] It can be seen from the embodiments that the device for measuring the cross-sectional dimensions of a square billet provided by the utility model can achieve the purpose of quickly measuring the height and width of the square billet, and has the characteristics of low manufacturing cost, simple operation and good use effect.
