Description

Technical Field

[0001] This utility model relates to the field of tooling technology in machining, and in particular to a tooling for measuring the inner and outer arc dimensions of a guide vane. Background Technology

[0002] When grinding the inner and outer diameters of guide vanes, many dimensions need to be measured, including arc dimensions and end face dimensions. The arc dimensions include both inner and outer diameters. Current measurement methods involve designing and manufacturing separate arc measuring tools and end face measuring tools. The measuring tool for the arc of the guide vane is a slide rail type, meaning a slide rail concentric with the vane's arc is designed on the measuring tool. During measurement, a dedicated measuring instrument base slides along the slide rail to measure the arc.

[0003] Current measurement methods require the design and manufacture of at least two sets of measuring instruments to measure the arc and end face of a single guide vane: an outer arc measuring instrument and an inner arc measuring instrument. Furthermore, due to the varying heights of the blade arcs, numerous different measuring bases must be manufactured for each arc height. This method involves numerous and cumbersome blade clamping operations, requires the design and manufacture of a large number of measuring instruments, has a long design and manufacturing cycle, and results in high manufacturing costs. During the measurement of the blade arc, the measuring base is pressed down by hand and slid along a slide rail; variations in pressure and hand tremors can lead to significant measurement instability.

[0030] Specifically, first, slide the head of the T-bolt 19 into the T-slot 37, then pass the screw 34 end of the T-bolt 19 upward through the through hole provided on the pad 2, and then connect it with the locking nut 20 by thread, thereby locking and fixing the T-bolt 19 by the locking nut 20.

[0031] To further ensure the stability of the connection between the locking nut 20 and the T-bolt 19, and to ensure the stability of the T-bolt 19 and the pad 2, a washer 21 is provided between the locking nut 20 and the upper surface of the pad 2, and the washer 21 is sleeved on the thread 34 of the T-bolt 19.

[0032] A pad 8 is fixedly provided on the upper surface of the pad block 2. The pad 8 is fixed to the pad block 2 by screws. The clamp assembly is fixedly provided on the upper surface of the pad 8.

Specifically, a connecting frame 36 is integrally or fixedly provided on the outer wall of the cantilever cylinder 16. The end of the connecting frame 36 away from the cantilever cylinder 16 is provided with an insertion hole. One end of the round rod slide column 17 is inserted into the insertion hole. The round rod slide column 17 is locked and fixed by connecting screws 25.

[0033] Multiple slide rod seats 12 are slidably provided on the round rod slide column 17.

The outer wall of the plug rod 33 abuts against the inner wall of the mounting hole 31. The plug rod 33 and the mounting hole 31 adopt a matching polygonal structure, which can realize the positioning of the plug rod 33, thereby preventing the rotating rod support 15 from rotating during use and avoiding affecting the measurement accuracy.

[0039] The top of the rotating rod support 15 is integrally provided with a vertically arranged rotating shaft 35. The top of the rotating rod support 15 and the bottom of the rotating shaft 35 form a stepped structure.

One end of the round rod sliding column 17 is fixedly connected to the outer wall of the cantilever rotating cylinder 16. The stepped structure formed by the top of the rotating shaft 35 and the rotating rod support 15 facilitates the installation of the thrust bearing 26, allowing the cantilever rotating cylinder 16 to rotate stably and smoothly axially on the rotating shaft 35.

The first positioning pin 7, the second positioning pin 10, the third positioning pin, the first positioning ball 3, the second positioning ball 4, and the positioning block 5 are all fixedly mounted on the base 1. The first positioning pin 7, the second positioning pin 10, and the positioning block 5 are used for planar positioning of the guide vane to be tested. The reference plane of the measuring instrument is selected to be parallel to the upper end face of the first positioning pin 7, the second positioning pin 10, and the positioning block 5. The first positioning ball 3 and the second positioning ball 4 are respectively used to position two points of the inner flow channel of the outer circle of the guide vane to be tested to ensure circumferential positioning. The third positioning ball 30 is fixed on the base 1 by the positioning seat 29 and is used to position the side of the guide vane to be tested to prevent the guide vane to be tested from rotating.

[0043] The pad 2 is fixedly equipped with an inner circle calibration block 9 for calibrating the inner circle design standard dimension of the guide vane to be measured, and an outer circle calibration block 6 for calibrating the outer circle design standard dimension of the guide vane to be measured. The inner circle calibration block 9 and the outer circle calibration block 6 enable calibration of the dial indicator being measured. Specifically, a positioning seat 29 is positioned and installed on the base 1 by fixing screws 23 and fixing pins 24, and the outer circle calibration block 6 and the inner circle calibration block 9 are fixedly installed on the positioning seat 29.

[0044] After clamping the guide vane to be measured using the fixture assembly, when measuring the outer or inner arc, the dial indicator is fixed on the dial indicator holder 13. The guide rod 18 is rotated to move the dial indicator to the outer circle dial indicator block 6 or the inner circle dial indicator block 9. The position of the dial indicator is adjusted for calibration. After the dial indicator is zeroed, the guide rod 18 is rotated again to move the dial indicator to the outer or inner arc to be measured for reading. The reading of the dial indicator is the difference between the actual radius and the theoretical radius of the measured outer or inner arc. Other dimensions are measured in the same way.
