Description

[Detailed description of the invention] "Field of industrial application" This invention relates to a fully automatic turbine blade inspection device.

``Prior art'' Conventionally, the dimensions of the turbine blades shown in Figures 6 and 7 have been manually inspected after manufacture or delivery (in the case of simple-shaped workpieces, material handling robots have been used) However, it is difficult to use this because of the complicated shape of turbine blades). In addition, it has been considered difficult to incorporate a stamping device into a dimension measuring device because stamping a trademark or the like on a turbine blade by stamping or pressing has a large effect on the workpiece.

``Problem that the invention seeks to solve'' This invention aims to automatically carry turbine blades into and out of a dimension measuring device after they have been manufactured or delivered, and to automatically carry out marking operations following dimension measurement. This is the purpose.

``Means for solving the problem'' This proposal has parallel workpiece loading and unloading grooves with adjustable groove width in the machine frame, and one end of the loading and unloading groove has a workpiece that can be slid freely on a rail in a direction perpendicular to the direction of the groove. A workpiece suspension groove fitting is arranged, and a workpiece dimension measuring device and a marking device are arranged in parallel along the rail, and the marking device receives the workpiece from the workpiece suspension groove fitting in a holder groove, and receives the workpiece from the workpiece suspension groove fitting in a holder groove. A fitting holder that is suspended in the groove, and a double-side facing press stamping metal fitting that presses both sides of the workpiece in the same linear direction parallel to the holder groove from two opposing directions toward the workpiece suspended in the holder groove. The system is comprised of a fully automatic turbine blade inspection system characterized by the following:

“Action” Work 8 (turbine blade) to be manufactured
When the lateral groove part of the base 8' is engaged with the starting end of the carry-in groove 2 and the main body 8'' is suspended and sequentially slid toward the end, the work suspended at the end of the carry-in groove 2 is suspended. The horizontal groove of the base 8' engages with the groove fitting 5, and the work body 8'' is slid in the direction of the rail 4 in a suspended state and stopped at a position corresponding to the dimension measuring device 6. Then, push the main body 8″ toward the measuring device 6 and place it in the holder 2 inside the measuring device 6.
4, the dimensions of the main body 8'' are measured.After measuring the dimensions, the main body 8'' is towed to the original groove fitting 5, suspended from the same fitting 5 as described above, and further along the rail 4. It is slid to a position corresponding to the next marking device 7 and stopped at that position. After stopping, press the main body 8'' to engage the holder 28 in the marking device 7 and suspend it, and in the suspended state press both sides of the base 8' toward the center with opposing press stamping metal fittings 9, 9 from both sides to apply pressure. After that, the main body 8'' is returned to the groove fitting 5, and slid along the rail 4 to the starting end of the carrying out groove 3, and then the main body 8'' is suspended in the carrying out groove 3, and it is attached to the terminal end of the carrying out groove 3. The groove width of the carry-in/out grooves 2 and 3 and the groove fitting 5 can be adjusted as appropriate according to changes in the size of the workpiece 8.

``Example'' A work suspension carry-in groove 2 and a carry-out groove 3 are provided in parallel on the upper surface of the machine frame 1. These grooves 2 and 3 are formed by parallel rods 2' and 3', respectively, and the groove width is adjusted to one handle 12 by a groove width adjustment device 11 (FIG. 2) provided at the bottom of the machine frame 1. At the same time, it is adjusted to the position between the solid line and the imaginary line in FIG. That is, handle 1
2 in the forward and reverse directions, the opposite screw rods 13, 13' rotate in the forward and reverse directions, causing the female screws 14, 14' to approach and separate, and the guide rail 1 perpendicular to the grooves 2, 3 to move toward and away from each other.
The sliding pieces 16 and 17 on 5 are brought close to each other and separated from each other via the movement connecting rods 18 and 19, and the parallel rods 2' and 3' connected to the same sliding pieces 16 and 17 are brought close to and separated from each other.
The driven pieces 16' and 17' connected to the links 6 and 17 by the interlocking rods 20 and 21 are separated from each other and brought closer to each other.
By moving the parallel rods 2', 3' connected to the groove 17' away from each other, the widths of the grooves 2, 3 can be adjusted simultaneously. Parallel rod 2′ made in this way,
At one end of 2', 3', and 3', a work suspension groove metal fitting 5 is arranged as shown in Figs. Then, it can be stopped at a position corresponding to the work size measuring device 6 and marking device 7 arranged on one side of the rail 4. The groove width of the groove fitting 5 is the groove width of the groove 2,
Can be manually adjusted to fit the width of 3. The metal fitting 5 is installed on the sliding table 23 via the vertical pillar 22,
The platform 23 can be moved back and forth by a drive pinion that meshes with a rack formed on the upper surface of the rail 4, and can be stopped at a fixed position. The dimension measuring device 6 has a fitting holder 24 in the horizontal groove of the base 8' of the suspended workpiece 8 (turbine blade) at a position in contact with the tip of the grooved metal fitting 5.
The workpiece 8 suspended from the groove fitting 5 is pushed by the cylinder 25, and the base part 8' is engaged and suspended from the holder 24 to be fixed, and in this state, the touch sensor 26 is raised and lowered to measure the dimensions. After the measurement, the workpiece 8 is pulled to the grooved metal fitting 5 by the magnetic adsorption cylinder 25', and the metal fitting 5 further stops along the rail 4 at a position corresponding to the next marking device 7, and the cylinder 27 pulls the workpiece 8 to the grooved metal fitting 5. The main body 8'' of the workpiece 8 is pushed into the holder 28, and the base 8' is supported in the holder groove of the holder 28, and the main body 8'' of the workpiece 8 is suspended from the holder 28. With the holder 28 rotated 90 degrees, the stamping device 7 is The pressing stamping metal fittings 9, 9 facing each other on both sides (see Figs. 4 and 5) rise horizontally from the solid line position in Fig. 3 to the imaginary line position, and the cylinder 2
9 and 29, the metal fittings 9 and 9 move from the solid line position in FIG. It can be stamped by pressure. At the time of this press stamping, even though the workpiece 8 is suspended, by the action of the pinion 31 that meshes between the opposing racks 30 and 30 (Fig. 4), the stamping metal fittings 9 are centripetally attached to both sides of the base 8'. , 9 and stamped. Thereafter, the workpiece 8 is pulled by the magnet 32 and the cylinder 27, moves to the original groove fitting 5, moves further along the rail 4, and reaches the starting end of the carry-out groove 3 (located by the imaginary line in Figs. 1 and 2). ), and is hooked with a claw provided on the loading/unloading device 33 and transferred to the terminal end of the carrying-out groove 3, where it is sequentially taken out. In addition, 34 in FIG. 1 is a cylinder for lifting and lowering the engraved metal fittings 9, 9, 35 is an arm for lifting and lowering, 36 is a holder 24,
28 pivot axes.

"Effects" Since the present invention is configured as described above, the dimensions of the manufactured or delivered workpiece 8 (turbine blade) can be automatically measured by the dimension measuring device 6, and also automatically stamped by the marking device 7. In particular, since the workpiece 8 can be moved in a suspended state, even if the workpiece 8 has a complicated shape, it can be safely and quickly measured and marked.

Furthermore, the marking operation is performed by a double-side facing press marking tool 9 that presses both sides of the workpiece 8 suspended in the holder groove from two opposing directions in parallel to the holder groove in the same linear direction. Therefore, even if the workpiece 8 is suspended and has a complicated shape, the pressing force of the metal fitting 9 acts centripetally on the workpiece 8, and marking can be performed safely and reliably.
