[0002] The stator blades are stationary blades fixed on the partition or guide vane holding ring. The stator blades in the steam turbine not only guide the steam flow, but also accelerate the steam. The stator blades in the steam chamber are called nozzles. The stator blades act as guide blades at the speed stage to change the direction of the steam flow into the next row of moving blades.

[0003] Generally, milling machines are often used to perform corresponding cutting operations on the end faces of the journals at both ends of the stator blades. However, it is difficult to perform cutting using only ordinary lathes. Utility Model Content

[0030] Embodiment 1

[0031] See also Figure 1-Figure 2 As shown in the figure, a fixed tool for blade grinding processing includes a spindle box 100 and a bed leg 200, a bed 300 is installed between the spindle box 100 and the bed leg 200, the spindle box 100 and the bed leg 200 are respectively located on both sides of the bed 300, a feed mechanism 400 is fixedly installed on the top of the bed 300, a fixed seat 500 is installed on the top of the feed mechanism 400, two fixed seats 500 are provided, and the two fixed seats 500 are symmetrically distributed about the central axis of the feed mechanism 400, a milling cutter 600 is transmission-connected to the side of the spindle box 100, and the milling cutter 600 is composed of a damping telescopic rod with a buckle and two cutter heads, and the fixed seat 500 on the top of the feed mechanism 400 is located on the bottom side of the milling cutter 600. Connect the original lathe's spindle box 100 to the milling cutter 600, and then fix the stator blades on the fixed seat 500. By starting the feed mechanism 400, the stator blades on the fixed seat 500 are transported to the milling cutter 600. After starting the milling cutter 600, the end faces of the shaft necks at both ends of the stator blades can be cut. By placing a fixture at the position of the tool holder of the original lathe and placing the tool at the position where the parts were originally placed, the lathe is improved to realize the function of the milling machine and expand the scope of application of the original lathe.

[0032] When in use, the original lathe spindle box 100 is connected to the milling cutter 600, and then the stator blade is fixed on the fixed seat 500. The stator blade on the fixed seat 500 is transported to the milling cutter 600 by starting the feeding mechanism 400. The milling cutter 600 is started to cut the end faces of the shaft necks at both ends of the stator blade.

[0033] To prevent over-clamping of the stator blades, refer to Figure 1-Figure 4As shown in the figure, a protective component 700 is provided on the top of the fixed seat 500, and the protective component 700 includes a rotating shaft 701, which is located at the top of the fixed seat 500. The rotating shaft 701 and the fixed seat 500 are in a rotational connection state. A fixed plate 702 is fixedly connected to the outer side of the rotating shaft 701, and a hydraulic device 703 is installed on the side of the fixed seat 500. A baffle 704 is rotatably connected to the inner wall of the hydraulic device 703, and an elastic rod 705 is fixedly connected to the side of the baffle 704. Two elastic rods 705 are provided, and the two elastic rods 705 are symmetrically distributed about the baffle 704. One end of the hydraulic device 703 is slidably connected to a force-bearing arc plate 706. When the stator blade needs to be fixed, the stator blade is placed on the fixing seat 500, and the fixing plate 702 fixedly connected to the rotating shaft 701 is rotated with the rotating shaft 701 as the axis, and the fixing plate 702 then drives the force arc plate 706 thereon to rotate toward the stator blade. A clamping rod 707 is slidably connected to one end of the hydraulic device 703, and an adjusting rod 709 is slidably connected to the other end of the hydraulic device 703. A limited rotating wheel 708 is fixedly connected to the side of the rotating shaft 701, and the clamping rod 707 is located at the bottom of the limited rotating wheel 708. When the stator blades are clamped, the stressed arc plate 706 is squeezed by the stator blades and moves toward the side of the hydraulic device 703. The baffle plate 704 rotatably connected to the hydraulic device 703 and the elastic rod 705 fixedly connected to the baffle plate 704 divide the hydraulic device 703 into two compartments, causing the clamping rod 707 slidingly connected to the hydraulic device 703 to move first. The clamping rod 707 clamps the limiting wheel 708 fixedly connected to the rotating shaft 701, which can limit the rotating shaft 701 and the fixed plate 702 from continuing to rotate, thereby preventing the device from excessively clamping the stator blades and improving the protection effect on the stator blades. After the cutting operation is completed, when the stator blades need to be removed, by pulling the adjusting rod 709 and cooperating with the hydraulic device 703 which is slidably connected to the adjusting rod 709, the baffle 704 can squeeze the elastic rod 705 close to the side of the adjusting rod 709 and cause rotation. At this time, the originally divided bins in the hydraulic device 703 are merged into one bin. By continuing to pull the adjusting rod 709, the clamping rod 707 and the force arc plate 706 can be moved to the side of the hydraulic device 703, thereby canceling the restriction of the limit wheel 708, and then the fixing plate 702 can be reset by rotating it, making the device easier to use.

[0034] During use, when the stator blade needs to be fixed, the stator blade is placed on the fixing seat 500, and the fixing plate 702 fixedly connected to the rotating shaft 701 is rotated with the rotating shaft 701 rotatably connected to the fixing seat 500 as the axis, and the fixing plate 702 immediately drives the force-bearing arc plate 706 thereon to rotate toward the stator blade; and when the stator blade is clamped, the force-bearing arc plate 706 can be squeezed by the stator blade and moved to one side of the hydraulic device 703, because the baffle plate 704 rotatably connected in the hydraulic device 703 and the elastic rod 705 fixedly connected to the baffle plate 704 divide the hydraulic device 703 into two compartments, thereby causing the clamping rod 707 slidingly connected to the hydraulic device 703 to move first, and the clamping The rod 707 clamps the limiting wheel 708 fixedly connected to the rotating shaft 701, which can limit the rotating shaft 701 and the fixed plate 702 from continuing to rotate; after the cutting operation is completed, when the stator blade needs to be removed, by pulling the adjusting rod 709 and cooperating with the hydraulic device 703 slidably connected to the adjusting rod 709, the baffle 704 can squeeze the elastic rod 705 close to the side of the adjusting rod 709 to produce rotation. At this time, the originally divided bins in the hydraulic device 703 are merged into one bin. Continuing to pull the adjusting rod 709 can move the clamping rod 707 and the force-bearing arc plate 706 to the side of the hydraulic device 703, thereby canceling the restriction of the limiting wheel 708, and then resetting it by rotating the fixed plate 702.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
