A kind of measuring tool for overflow brick transport frame angle

Abstract

This utility model discloses a measuring fixture for the angle of an overflow brick transport rack, belonging to the field of glass manufacturing equipment technology. The measuring fixture for the angle of an overflow brick transport rack provided by this utility model includes, from top to bottom, a first component and a second component. The second component adopts a right triangular prism structure, and the included angle formed by its two non-parallel surfaces strictly matches the angle of the tip of the overflow brick, forming an absolute reference angle. When measuring the front, middle, and rear sections of the overflow brick transport rack, by perpendicularly attaching the two parallel surfaces of the measuring fixture to the ground, a unified spatial coordinate system can be quickly established, eliminating the angle dispersion problem caused by welding deformation and material cutting errors. Compared with traditional manual point-by-point measurement, this structure transforms angle detection into a direct "fit-alignment" judgment, directly quantifying the angle deviation of the three sections, achieving accurate detection, and ensuring that the inclination angle of the bearing surface and the included angle of the brick are perfectly matched throughout the entire length of the overflow brick transport rack.

Description

Technical Field

[0001] The utility model relates to the technical field of glass manufacturing equipment, and particularly relates to a measuring tool for the angle of an overflow brick transport rack. Background Technique

[0002] As a core component of special-shaped refractory materials in the overflow glass process, the outer contour of the overflow brick has a key included angle θ, and the accuracy of this included angle directly affects the flow state distribution of the glass melt during the forming process and the thickness uniformity of the product. After being processed by a numerical control machine tool, the overflow brick needs to be transported across regions through an overflow brick transport rack, and the matching degree between the overflow brick transport rack and the key included angle θ will produce a double technical effect: on the one hand, an angular deviation exceeding 0.5° will cause local stress concentration at the brick tip during transportation, resulting in hidden damage to precision components worth millions; on the other hand, although the overflow brick transport racks of each generation of products (such as G3.5 / G6 / G7.5 / G8.5) have generational differences in the three-dimensional dimensions of length, width, and height, it is necessary to ensure the full-series consistency of the key included angle θ to adapt to the rapid product changeover requirements of the production line.

[0003] The body of the existing overflow brick transport rack is a profiled rectangular tube with a specification of 80mm x 40mm x 5mm. In actual production, due to factors such as下料精度误差、焊接热变形及工装定位偏差等因素, it is difficult to keep the included angles at the three key positions of the front, middle, and rear in the length direction of the overflow brick transport rack consistent.

[0004] Moreover, the traditional manual measurement method relies on an angle gauge for detection. Affected by the experience of the operator, it is impossible to accurately detect the inclination angles of the front, middle, and rear three sections, resulting in an increased risk of component damage caused by uneven stress distribution during transportation. Given that the overflow brick is hard, brittle, and has a large self-weight, the angular deviation in the transportation link has become a key bottleneck restricting the product qualification rate.

[0005] Therefore, how to provide a measuring tool that can accurately detect the inclination angles of the front, middle, and rear three sections of the overflow brick transport rack has become a technical problem that needs to be urgently solved by those skilled in the art. Summary of the Invention

[0006] The purpose of the utility model is to provide a measuring tool for the angle of an overflow brick transport rack to overcome the problem of insufficient detection accuracy of the inclination angle of the overflow brick transport rack due to the influence of experience in the traditional manual measurement method in the prior art.

[0007] The utility model solves the above technical problems through the following technical solutions:

The second component adopts a right triangular prism structure, and the included angle formed by its two non-parallel surfaces strictly matches the tip angle of the overflow brick, forming an absolute reference angle.

Compared to traditional manual point-by-point measurement, this structure transforms angle detection into a direct "fit-alignment" judgment, directly quantifying the angle deviation of the three sections, achieving accurate detection, and ensuring that the inclination angle of the bearing surface and the included angle of the brick are perfectly matched throughout the entire length of the overflow brick transport rack.

[0020] Furthermore, a horizontal through hole is provided in the middle of the first component to enable linear sliding adjustment of the measuring fixture along the length direction (front zone, middle zone, rear zone) of the overflow brick transport frame.

[0021] Furthermore, the measuring fixture is made of Q235 steel, which has both good rigidity and resistance to deformation. This ensures that it can withstand the contact pressure of the transport frame's bearing surface during the measurement process, thus avoiding measurement deviations caused by deformation of the measuring fixture itself.

[0046] Example 1

[0047] A measuring fixture for the angle of an overflow brick transport rack comprises, from top to bottom, a first component and a second component. The second component is shaped like a right triangular prism, comprising two parallel surfaces and three non-parallel surfaces. One non-parallel surface is fixedly connected to the bottom of the first component. The included angle formed by the other two non-parallel surfaces is equal to the angle of the tip of the overflow brick to be transported. When measuring the angle of the overflow brick transport rack, the two parallel surfaces are perpendicular to the ground. A horizontal through hole 2 is provided in the middle of the first component. The center of the horizontal through hole 2 is located 30mm downward from the upper end surface of the first component. The diameter of the horizontal through hole 2 is 20mm. The first component is shaped like a cuboid. The length of the first component is 150mm. The width of the first component is 99mm. The thickness of the first component is 10mm. The length of the second component is 150mm. The width of the second component is 201mm. The thickness of the second component is 10mm. The first and second components are made of Q235 steel. The first and second components are integrally formed.

[0048] During the welding process of the overflow brick transport frame 3, the tilt angles of the three parts of the overflow brick transport frame 3 are checked one by one using the measuring fixture 1 as a reference to ensure that the welding angle dimensions of the three parts meet the product transportation requirements. During the measurement process, the two inclined surfaces of the measuring fixture 1 are tightly attached to the corresponding inclined surfaces of the transport frame, with no gaps on the corresponding sides, indicating that the welding angle of the transport frame meets the requirements. The measuring fixture 1 is designed, programmed using computer 3D software, and machined using a CNC machine tool. The machined measuring fixture 1 is then checked using calipers and angle gauges. The measuring fixture 1, which performs dimensional and angle checks to meet design requirements, can be used as a measuring tool for inspecting the transport frame. When measuring on the overflow brick transport frame 3, the measuring fixture 1 should be placed vertically and stably at the included angle in the middle of the width of the transport frame, and the degree of fit between the two inclined surfaces of the measuring fixture 1 and the corresponding two inclined surfaces of the transport frame should be observed. It should then be placed sequentially at the included angles of the front area 4, middle area 5, and rear area 6 of the transport frame. As can be seen, the testing fixture solves the problem of consistent tilt angle of the overflow brick transport frame 3, and provides a guarantee for the safe transport of overflow bricks.
