[0026] Example 1
[0027] Embodiment 1 of this utility model is an adjustable clamping device for turbine blade processing, including a base 1 and a drive assembly 3 located inside the base 1. A width adjustment assembly 2 and a clamping assembly 4 are arranged sequentially above the drive assembly 3. The width adjustment assembly 2 has an adjustment plate 20 and an adjustment plate 21 that adjust the width according to the movement of the drive assembly 3. The clamping plate 45 in the clamping assembly 4 adjusts the clamping distance by moving up and down the clamping plate 44.
[0028] Reference Figures 1 to 3In this application, a drive assembly 3 is mainly installed inside the base 1. The drive assembly 3 controls the distance between the adjusting plate 20 and the adjusting plate 21 of the width adjustment assembly 2, so that the clamping plates 44 and 45 in the clamping assembly 4 at this distance meet the clamping requirements of the turbine blade to be processed. At the same time, a stable clamping is performed during the clamping process. On the one hand, the adjusting plate 20 and the adjusting plate 21 are fixed in position and firmly connected under the drive of the drive assembly 3; on the other hand, they are firmly clamped by the combined clamping of the clamping plates 44 and 45, preventing them from falling off during processing.
[0029] In some preferred embodiments, the installation positions of clamping plate 44 and clamping plate 45 are as follows: the clamping assembly 4 includes a column 40 located above the adjusting plate 20 and the adjusting plate 21 respectively. The top of the column 40 is provided with a sliding groove 400, and the bottom of the sliding groove 400 is provided with a mounting groove 401. The clamping plate 44 is located in the mounting groove 401, and the clamping plate 45 is located in the sliding groove 400 and moves up and down.
[0030] The mounting groove 401 provides a fixed mounting condition for the clamping plate 44. The clamping plate 44 is fixed inside the mounting groove 401 by welding or other fixed connection methods. At the same time, a clamping plate 45 that can move up and down is provided in the sliding groove 400. The distance between the two clamping plates can be adjusted by moving them up and down above the clamping plate 44 to meet the clamping requirements of different turbine blade ends. This ensures stable clamping of the two ends of the turbine blades with different thicknesses.
[0031] In order to drive the clamping plate 45 to move up and down, a lead screw 41 is provided inside the sliding groove 400, and a sliding block 42 is sleeved on the outer periphery of the lead screw 41 and connected to the clamping plate 45. The top end of the lead screw 41 is connected to the output end of the rotary motor 43.
[0032] Specifically, a lead screw 41 is installed in the sliding groove 400. Driven by the rotary motor 43, the lead screw 41 rotates, causing the sliding block 42 to move linearly along the lead screw 41. During the movement, the clamping plate 45 moves closer to or further away from the clamping plate 44 to adjust the clamping distance between them, thus achieving the clamping and fixing of turbine blades of different thicknesses. The clamping plate 44 provides the bearing conditions for placing the turbine blade. Simply place the turbine blade above the two clamping plates 44, then start the rotary motor 43 to move the clamping plate 45 up and down to adjust the clamping distance.
[0033] To improve the clamping strength and protection, rubber pads 46 with protrusions 460 are respectively provided on the opposite surfaces of the clamping plate 44 and the clamping plate 45. The protrusions 460 of the clamping plate 44 and the clamping plate 45 are staggered. By providing rubber pads 46 and protrusions 460, and staggering the protrusions 460, during the clamping process, the protrusions 460 fully contact the turbine blade, and this end is fully clamped. At the same time, the protrusions 460 and the rubber pads 46 protect the turbine blade from surface damage during the clamping process. Figure 4 .
[0034] In some preferred embodiments, a reinforcing rod 47 is provided at the bottom of the clamping plate 44 and fixedly connected to the column 40. Support seats 48 are respectively provided above the adjusting plate 20 and the adjusting plate 21, and the bottom end of the column 40 is located within the support seat 48. The reinforcing rod 47 and the support seat 48 are both fixedly connected to further enhance the stability of the clamping plate 44 and the column 40 during installation, thereby improving stability during subsequent processing.
[0035] Example 2
[0036] This embodiment 2 is implemented based on embodiment 1. The end of the first adjustment plate 20 is provided with a telescopic rod 200, and the end of the second adjustment plate 21 is provided with a sleeve 210. The telescopic rod 200 is located in the telescopic hole 211 inside the sleeve 210 and the second adjustment plate 21.
[0037] In the width adjustment assembly 2, a telescopic rod 200 and a sleeve 210 are respectively provided between the first adjustment plate 20 and the second adjustment plate 21. When adjusting the width in the initial state, the first adjustment plate 20 and the second adjustment plate move in opposite directions under the action of the drive assembly 3. The telescopic rod 200 then moves inside the second adjustment plate 21 and the sleeve 210, widening the distance between the first adjustment plate 20 and the second adjustment plate 21, so that the distance meets the clamping width of the turbine blade relative to the first clamping plate 44 and the second clamping plate 45. At the same time, a limiting plate is provided at the end of the telescopic rod 200 located in the telescopic hole 211, and a limiting hole is provided on the sleeve 210 near the telescopic hole 211 of the first adjustment plate 20, to prevent the telescopic rod 200 from detaching from the telescopic hole 211 as a whole.
[0038] Meanwhile, the number of telescopic rods 200 and sleeves 210 is multiple, which effectively improves the connection between the first adjusting plate 20 and the second adjusting plate 21.
[0039] Example 3
[0040] This embodiment 3 is implemented based on embodiment 1. The drive assembly 3 includes a dual drive motor 30. The dual drive motor 30 is located in the moving groove 10 of the base 1. Two bidirectional threaded rods 31 are respectively provided at both ends of the dual drive motor 30. Moving blocks 33 connected to the first adjustment plate 20 and the second adjustment plate 21 are respectively sleeved on the outer periphery of the bidirectional threaded rods 31.
[0041] Specifically, refer to Figure 1 and Figure 2 The opposing movements of adjusting plate 1 20 and adjusting plate 21 are mainly driven by the dual-drive motor 30, which drives the bidirectional threaded rods 31 on both sides to rotate in opposite directions. This, in turn, drives the moving block 33 to adjust the distance between adjusting plate 1 20 and adjusting plate 21, thereby allowing the telescopic rod 200 to extend and retract within the telescopic hole 211. When the distance between adjusting plate 1 20 and adjusting plate 21 is determined, the dual-drive motor 30 is turned off. Since the bidirectional threaded rods 31 are composed of threads, after being turned off, the moving block 33 is threadedly connected to the bidirectional threaded rods 31, ensuring the stability of the position at this time, thereby ensuring the stability of the two columns 40.
[0042] Meanwhile, a mounting base 32 is provided at the bottom of the dual drive motor 30, and the two ends of the mounting base 32 are respectively provided on the guide rod 11 that passes through the bottom of the moving block 33. The guide plate is provided to prevent the moving block 33 from moving linearly, and the mounting base 32 provides conditions for the installation of the dual drive motor 30, avoiding direct contact between the dual drive motor 30 and the bottom of the moving groove 10, which would reduce its service life.
[0043] The working principle of this utility model is as follows: When in use, the dual drive motor 30 is started, and the moving block 33 drives the adjusting plate 20 and the adjusting plate 21 to move in opposite directions to a suitable distance. The installation of the telescopic rod 200 in the telescopic hole 211 ensures the connection stability of the adjusting plate 20 and the adjusting plate 21. The turbine blade is placed above the two clamping plates 44, and the rotary motor 43 is started respectively, so that the lead screw 41 rotates and drives the sliding block 42 and the clamping plate 45 to move down to the surface of the turbine blade for clamping. The surface of the turbine blade is in full contact with the protrusion 460, which not only clamps it firmly but also protects the surface to prevent damage and improves the pass rate of the turbine blade after processing.
[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of the present utility model and within the spirit and principles of the present utility model shall still fall within the protection scope of the present utility model.
