[0028] Please see Figures 1 to 4 As shown, this embodiment provides a quick-change device for three-coordinate inspection and positioning of steam turbine blades, which includes a base 10, a fixing component 20, and a limiting component 30. The fixing component 20 is disposed on the base 10, and the limiting component 30 is detachably connected to the fixing component 20 via a disassembly / assembly component 40. The fixing component 20 includes a driving component 21, a first clamping component 22, and a second clamping component 23. The driving component 21 is disposed at the first end of the base 10 in the horizontal direction, and the driving end of the driving component 21 is connected to the first clamping component 22. The second clamping component 23 is disposed on the base 10. At the second end along the horizontal direction, the driving member 21 is configured to drive the first clamping member 22 to approach or move away from the second clamping member 23 to clamp the first end of the workpiece. The limiting assembly 30 includes a support member 31 and at least one set of adjusting assemblies 32. The support member 31 is vertically adjustable on the second clamping member 23 via a disassembly member 40. A first waist-shaped hole 33 is provided on the support member 31 along the vertical direction. The adjusting assembly 32 is adjustablely disposed in the first waist-shaped hole 33. The adjusting assembly 32 is configured to limit the second end of the workpiece.

[0029] Specifically, the workpiece is a blade.

[0030] Specifically, the drive component 21 is one of a cylinder, an electric motor, or a hydraulic cylinder.

[0031] Specifically, support member 31 is a support plate.

[0032] As can be seen, the driving component 21 of the fixing component 20 can drive the first clamping component 22 to approach or move away from the second clamping component 23, which can quickly clamp the first end of the workpiece and improve the detection efficiency. At the same time, through the cooperation of the base 10, the disassembly component 40, the support component 31 and the adjustment component 32, different types of blades can be quickly adjusted, which improves the efficiency of changing tooling.

[0033] In one embodiment, the adjustment component 32 includes a first adjustment member 34 and at least two second adjustment members 35. The first end of the first adjustment member 34 is adjustablely disposed in the first waist-shaped hole 33. The first adjustment member 34 has a second waist-shaped hole 36 along its own length direction. The second adjustment members 35 are disposed in the second waist-shaped hole 36 and can be reciprocated in the horizontal direction.

[0034] Specifically, the adjustment assembly 32 includes a first adjustment member 34 and two second adjustment members 35, both of which are disposed in the second oblong hole 36 and can reciprocate in the horizontal direction.

[0035] As can be seen, the first adjusting member 34 can move vertically within the first oblong hole 33 to adjust the height position, and the second adjusting member 35 can reciprocate horizontally on the first adjusting member 34 to adjust the horizontal position. This can adapt to the shape and size of different workpieces, further improve the accuracy of limiting the second end of the workpiece, and ensure the stability of the workpiece position during the inspection process.

[0036] In one embodiment, the second clamping member 23 has at least two first limiting holes spaced apart vertically on the opposite side of the side abutting the workpiece, and the support member 31 has a second limiting hole. The disassembly and assembly member 40 passes through the first limiting hole and connects to the second limiting hole to connect the support member 31 to the second clamping member 23 in an adjustable manner along the vertical direction.

[0037] Specifically, the disassembly / assembly part 40 can be a pin or a screw.

[0038] As can be seen, the first limiting hole on the second clamping member 23 and the second limiting hole on the support member 31 are connected by the disassembly and assembly part 40, so that the support member 31 can be adjusted and installed on the second clamping member 23 in the vertical direction. The operation is simple and convenient, which improves the flexibility of the device and the work efficiency.

[0039] In one embodiment, the second adjusting member 35 includes a slider 350 and a limiting plate 351. The slider 350 is movably disposed in the second oblong hole 36, and the limiting plate 351 is fixedly mounted on the slider 350.

[0040] Specifically, a screw is provided on the slider 350. The screw passes through the second oblong hole 36 and connects to the limiting plate 351. The screw nut and the limiting plate 351 are located on both sides of the second oblong hole 36, so that the slider 350 and the limiting plate 351 are movably disposed in the second oblong hole 36.

[0041] As can be seen, the slider 350 of the second adjusting member 35 can move in the second oblong hole 36, and the limiting plate 351 is fixed on the slider 350, so that the limiting plate 351 can accurately reach the preset position and stably limit the second end of the workpiece, ensuring the stability of the second adjusting member 35 in the limiting process, preventing inaccurate limiting due to shaking or displacement, and ensuring the reliability of the test results.

[0042] In one embodiment, the first clamping member 22 includes a first support block 220, a first transmission block 221 and a first clamping block 222. The driving end of the driving member 21 is connected to the first support block 220. A first mounting groove is provided on the first support block 220. The first transmission block 221 is vertically fixedly installed in the first mounting groove. A second mounting groove is provided on the side of the first transmission block 221 near the second clamping member 23. The first clamping block 222 is fixedly installed in the second mounting groove.

[0043] As can be seen, the layered structure composed of the first support block 220, the first transmission block 221 and the first clamping block 222 enables the clamping force to be evenly transmitted to the workpiece, which enhances the clamping stability of the first end of the workpiece and prevents the workpiece from loosening or shifting during the inspection process.

[0044] In one embodiment, the bottom of the first support block 220 is provided with a sliding groove 223, and the base 10 is provided with a sliding rail 11 in the horizontal direction. The sliding groove 223 is movably mounted on the sliding rail 11.

[0045] As can be seen, by cooperating with the slide rail 11 through the slide groove 223, the first support block 220 can move in the horizontal direction, which reduces the friction when the first clamping member 22 moves, and ensures that the drive member 21 can easily drive the first clamping member 22 to approach or move away from the second clamping member 23, thereby improving the ease of operation and response speed of the device.

[0046] In one embodiment, the second clamping member 23 includes a second support block 230, a second transmission block 231, and a second clamping block 232. The second support block 230 is fixedly installed on the base 10. A third mounting groove is provided on the second support block 230. The second transmission block 231 is vertically fixedly installed in the third mounting groove. A fourth mounting groove is provided on the side of the second transmission block 231 near the first clamping member 22. The second clamping block 232 is fixedly installed in the fourth mounting groove.

[0047] As can be seen, the combination of the second support block 230, the second transmission block 231, and the second clamping block 232 corresponds to the structure of the first clamping member 22. The second support block 230 is fixed on the base 10 to provide stable support, the second transmission block 231 transmits force to the second clamping block 232, and the second clamping block 232 works together with the first clamping block 222 to stably clamp the first end of the workpiece.

[0048] In one embodiment, the base 10 has a first mounting hole at its second end along the horizontal direction, and the bottom of the second support block 230 has a corresponding second mounting hole. The first mounting hole and the second mounting hole are connected by fasteners, thereby connecting the base 10 and the second support block 230.

[0049] Specifically, the fastener is a screw.

[0050] As can be seen, the cooperation of the first mounting hole, the second mounting hole and the fasteners makes the second support block 230 stably installed on the base 10, which enhances the connection stability between the second clamping member 23 and the base 10, and prevents the second clamping member 23 from being displaced or shaking due to external force during the detection process, thereby ensuring the reliability and detection accuracy of the entire device.
