Description

Technical Field

[0001] This utility model relates to the field of grinding fixture technology, and in particular to a grinding fixture for turbine blade crowns. Background Technology

[0002] The blade crown is part of the turbine blade structure. However, grinding is an important process in the manufacturing of turbine blades. For turbine blades with crown structures, grinding of the crown is particularly critical. Grinding can remove burrs and roughness from the surface of the crown, making it smooth and uniform. This helps to reduce fluid resistance and improve turbine efficiency.

[0003] However, due to the complex shape of turbine blades, unstable clamping of turbine blades can easily lead to problems such as turbine blade movement and deformation. In addition, a large amount of dust will inevitably be generated during the grinding process of turbine blade crowns. If this dust is not treated, it will not only affect the working environment, but also endanger the health of workers. Utility Model Content

[0004] The main purpose of this utility model is to provide a turbine blade crown grinding fixture, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A turbine blade crown grinding fixture includes a first base and a second base. A controller is fixedly installed on the left front end of the first base. A first servo motor and a second servo motor are respectively fixedly installed on the right ends of the first base and the second base. A dust collection device is fixedly installed on the upper right end of the first base and the second base. A first groove and a second groove are respectively opened on the upper end of the first base and the second base.

[0007] Preferably, the dust collection device includes a mounting box. An exhaust pipe is fixedly installed at the rear left end of the mounting box. A filter and a dust collection box are respectively installed at the front right end of the mounting box. The filter is located on top of the dust collection box. A fan is installed at the front end of the mounting box. The fan is fixedly installed on the upper end of a first base, and the mounting box is fixedly installed on the upper end of a second base. By activating the fan, suction is generated within the exhaust pipe on the mounting box, thereby sucking up the dust generated during blade grinding and cleaning the dust produced during grinding.

[0008] Preferably, a first-hand and second-hand screw is fixedly installed at the output end of the first servo motor. A first-hand slider is installed on both the forward and reverse threads of the first-hand and second-hand screw. A first-hand contour clamp is fixedly installed on the upper end of each of the two first-hand sliders. The first-hand and second-hand screw is rotatably installed within a first-hand groove. The first-hand and second-hand screw at its output end is rotated by the first servo motor. Since the two first-hand sliders are threaded onto the forward and reverse threads of the first-hand and second-hand screws respectively, when the first-hand and second-hand screws rotate, the two first-hand sliders will move closer to each other, thereby causing the two first-hand contour clamps to clamp a portion of the turbine blade.

[0009] Preferably, a second forward and reverse screw is fixedly installed at the output end of the second servo motor. A second slider is installed on both the forward and reverse threads of the second forward and reverse screws. A second contouring clamp is fixedly installed on the upper end of each of the two second sliders. The second forward and reverse screws are rotatably installed within a second sliding groove. By driving the second forward and reverse screws with the second servo motor, the two second contouring clamps clamp the other part of the turbine blade, thereby improving the stability of the clamping device.

[0010] Preferably, the controller is electrically connected to the first servo motor, the second servo motor, and the fan.

[0011] Preferably, there is a gap between the first contouring clamp and the second contouring clamp.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. First, place the turbine blade to be ground between two No. 1 contouring clamps. Then, drive the No. 1 forward and reverse screws at its output end through the No. 1 servo motor to rotate. Since the two No. 1 sliders are respectively threaded onto the forward and reverse threads of the No. 1 forward and reverse screws, when the No. 1 forward and reverse screws rotate, the two No. 1 sliders will move closer to each other, thereby clamping part of the turbine blade with the two No. 1 contouring clamps. Similarly, drive the No. 2 forward and reverse screws through the No. 2 servo motor, thereby clamping the other part of the turbine blade with the two No. 2 contouring clamps, thus improving the stability of the clamping device.

[0014] 2. When the turbine blade crown is being ground, the fan is started, which generates suction in the exhaust pipe on the mounting box, thereby sucking up the dust generated during the crown grinding. The sucked-up dust enters the mounting box, is filtered by a filter screen, and is collected by a dust collection box. Both the filter screen and the dust collection box are installed inside the mounting box, making them easy to remove. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figures 1-4As shown, a turbine blade crown grinding fixture includes a first base 1 and a second base 5. A controller 6 is fixedly installed on the left front end of the first base 1. A first servo motor 3 and a second servo motor 4 are respectively inserted and fixedly installed on the right ends of the first base 1 and the second base 5. A dust collection device 2 is fixedly installed on the upper right end of the first base 1 and the second base 5. A first sliding groove 7 and a second sliding groove 8 are respectively opened on the upper end of the first base 1 and the second base 5.

[0024] The dust collection device 2 includes a mounting box 20. An exhaust pipe 21 is fixedly installed at the rear left end of the mounting box 20. A filter 23 and a dust collection box 24 are respectively installed at the front right end of the mounting box 20. The filter 23 is located on top of the dust collection box 24. A fan 22 is installed at the front end of the mounting box 20 and is fixedly installed on the upper end of the first base 1. The mounting box 20 is fixedly installed on the upper end of the second base 5. The controller 6 is electrically connected to the first servo motor 3, the second servo motor 4, and the fan 22. By starting the fan 22, suction is generated in the exhaust pipe 21 on the mounting box 20, thereby sucking up the dust generated during blade grinding and cleaning the dust produced during grinding.

[0025] A first-hand screw 30 is fixedly installed at the output end of the first servo motor 3. A slider 31 is installed on both the forward and reverse threads of the first-hand screw 30. A first-shaped clamping block 32 is fixedly installed on the upper end of each slider 31. The first-hand screw 30 is rotatably mounted within the first sliding groove 7. The first-hand screw 30 is rotated by the first servo motor 3. Since the two sliders 31 are threaded onto the forward and reverse threads of the first-hand screw 30 respectively, when the first-hand screw 30 rotates, the two sliders 31 will move closer to each other, thereby clamping a portion of the turbine blade with the two first-shaped clamping blocks 32.

[0026] A second-order forward and reverse screw 40 is fixedly installed at the output end of the second servo motor 4. A second-order slider 41 is installed on both the forward and reverse threads of the second-order forward and reverse screw 40. A second-order contour clamping block 42 is fixedly installed on the upper end of each of the two second-order sliders 41. The second-order forward and reverse screw 40 is rotatably installed within the second-order sliding groove 8. There is a gap between the first-order contour clamping block 32 and the second-order contour clamping block 42. The second-order forward and reverse screw 40 is driven by the second servo motor 4, thereby causing the two second-order contour clamping blocks 42 to clamp the other part of the turbine blade, thus improving the stability of the clamping device.

[0027] It should be noted that this utility model is a turbine blade crown grinding fixture. First, the controller 6 is connected to an external power source. Then, the turbine blade to be ground is placed between two No. 1 contouring clamps 32. At this time, the No. 1 servo motor 3 drives the No. 1 forward and reverse screw 30 at its output end to rotate. Since the two No. 1 sliders 31 are respectively threaded onto the forward and reverse threads of the No. 1 forward and reverse screw 30, when the No. 1 forward and reverse screw 30 rotates, the two No. 1 sliders 31 will move closer to each other, thereby clamping a portion of the turbine blade between the two No. 1 contouring clamps 32. Similarly, through... The second servo motor 4 drives the second forward and reverse screw 40, thereby clamping the other part of the turbine blade with the two second contour clamping blocks 42, thus improving the stability of the device clamping. When the turbine blade crown is being ground, the fan 22 is started, which generates suction in the exhaust pipe 21 on the mounting box 20, thereby sucking up the dust generated during the crown grinding. The sucked-up dust enters the mounting box 20 and is filtered by the filter screen 23, and then collected by the dust collection box 24. The filter screen 23 and the dust collection box 24 are both inserted into the mounting box 20, which is also convenient for removal.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
