Description

Technical Field

[0001] This invention relates to the field of metallurgical machinery maintenance and measurement technology, and in particular to a testing fixture for measuring the dimensional accuracy of equipment. Background Technology

[0002] In the on-site precision measurement and adjustment of hot and cold rolling production line equipment (such as stands, stands, and housings), the working space is usually confined, requiring multiple people to work together and using various measuring tools in sequence. The existing testing tools and dial indicator supports are continuously adjusted in position and height to achieve accurate measurement of the equipment's dimensions and tolerances. Measurement of components that are obscured and cannot be directly measured is particularly difficult, requiring the disassembly of externally covered components, leading to increased labor intensity during equipment disassembly and assembly, and low measurement and maintenance efficiency.

[0003] During the repair and assembly of large equipment, the excessive size of the assembled equipment makes it impossible to use its X, Y, and Z axes to measure the accuracy of its shape and position dimensions when placed on the machine tool platform. Or, when multiple repairs and adjustments are required, the equipment must be repeatedly hoisted and placed on the machine tool platform, resulting in increased labor intensity and low measurement and maintenance efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a testing fixture for measuring the dimensional accuracy of equipment. This testing fixture overcomes the defects of traditional on-site accuracy measurement operations of rolling mill equipment and dimensional accuracy testing during the repair and assembly of large equipment. It can be flexibly set at the measurement position of the equipment, and a reference surface can be established to extend the points that are blocked and cannot be directly measured to the measurable position, thereby reducing the process of disassembling and assembling equipment and repeated hoisting, and improving the efficiency of measurement operations.

[0005] To solve the above-mentioned technical problems, the present invention provides a testing fixture for measuring the dimensional accuracy of equipment, comprising a support platform trolley, a Z-axis manual precision fine-tuning lifting platform, an X-axis manual precision fine-tuning slide, a Y-axis manual precision fine-tuning slide, a dial indicator, and a magnetic displacement sensor. The X-axis manual precision fine-tuning slide is disposed on the platform surface of the support platform trolley. The Y-axis manual precision fine-tuning slide is disposed on the X-axis manual precision fine-tuning slide and is driven to move along the X-axis. The Z-axis manual precision fine-tuning lifting platform is disposed on the Y-axis manual precision fine-tuning slide and is driven to move along the Y-axis. The dial indicator and the magnetic displacement sensor are respectively disposed on the Z-axis manual precision fine-tuning lifting platform and are driven to move up and down along the Z-axis.

[0006] Furthermore, the support platform trolley is equipped with parking wheels at each of the four corners of its bottom. Because the inspection fixture of this invention for measuring the dimensional accuracy of equipment adopts the above-mentioned technical solution, namely, the X-axis manual precision fine-tuning slide is set on the platform surface of the support platform trolley, the Y-axis manual precision fine-tuning slide is set on the X-axis manual precision fine-tuning slide and moves along the X-axis driven by the X-axis manual precision fine-tuning slide, the Z-axis manual precision fine-tuning lifting platform is set on the Y-axis manual precision fine-tuning slide and moves along the Y-axis driven by the Y-axis manual precision fine-tuning slide, and the dial indicator and magnetic displacement sensor are respectively set on the Z-axis manual precision fine-tuning lifting platform and move up and down along the Z-axis driven by the Z-axis manual precision fine-tuning lifting platform. This inspection fixture overcomes the defects of traditional on-site precision measurement operations of rolling mill equipment. It can be flexibly set at the measurement position of the equipment, and a reference surface can be established to extend the points that are blocked and cannot be directly measured to the measurable position, reducing equipment disassembly and assembly procedures and improving measurement operation efficiency. Attached Figure Description

[0007] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments: Figure 1 This is a schematic diagram of the inspection fixture used for measuring the dimensional accuracy of equipment according to the present invention; Figure 2 for Figure 1 Side view. Detailed Implementation

[0008] Implementation, for example Figure 1 and Figure 2 As shown, the inspection fixture for measuring the dimensional accuracy of equipment according to the present invention includes a support platform trolley 1, a Z-axis manual precision fine-tuning lifting platform 2, an X-axis manual precision fine-tuning slide 3, a Y-axis manual precision fine-tuning slide 4, a dial indicator 5, and a magnetic displacement sensor 6. The X-axis manual precision fine-tuning slide 3 is disposed on the platform surface of the support platform trolley 1. The Y-axis manual precision fine-tuning slide 4 is disposed on the X-axis manual precision fine-tuning slide 3 and is driven to move along the X-axis. The Z-axis manual precision fine-tuning lifting platform 2 is disposed on the Y-axis manual precision fine-tuning slide 4 and is driven to move along the Y-axis. The dial indicator 5 and the magnetic displacement sensor 6 are respectively disposed on the Z-axis manual precision fine-tuning lifting platform 2 and are driven to move up and down along the Z-axis.

[0009] Preferably, the support platform trolley 1 is provided with parking rollers 11 at the four corners of its bottom.

[0010] The support platform trolley serves as the basic working surface of the entire testing fixture and also as its fixed support plane, thereby stably supporting the measurement operations of various equipment data.

[0011] This testing fixture has a simple structure and small size. Supported by a trolley, it can be flexibly installed on equipment such as rolling mill frames, stands, and boxes. The dial indicator and magnetic displacement sensor can be moved along the X, Y, and Z axes using a Z-axis manual precision fine-tuning lifting table, an X-axis manual precision fine-tuning slide, and a Y-axis manual precision fine-tuning slide. This allows for direct measurement of relative dimensions and tolerances, and also enables the establishment of a reference surface to extend obscured points that cannot be directly measured to measurable locations, thereby improving measurement efficiency and reducing equipment disassembly and assembly procedures.

[0012] This testing fixture, with its simple structure, effectively solves the problem of inconvenient measurement in areas such as frames, archways, and boxes due to limited space. It supports the use of various measuring instruments, enabling not only dimensional measurement but also geometric and positional measurement and tolerance measurement. It is also easy to use and maintain.
