Description

Technical Field

[0001] The utility model belongs to the technical field of clamp devices, in particular to a vibration-proof table for processing annular aviation parts. Background Art

[0002] As a highly complex and sophisticated thermal machine, aircraft engines have a wide variety of components, comprising tens of thousands of parts. These components are primarily forged or cast, depending on the processing method. Ring forgings are a key component in aircraft engines and require machining to qualify. The machining accuracy of these ring-shaped parts significantly determines the performance and service life of these critical aircraft components. The contours of ring-shaped parts generally consist of an outer circle, an inner hole, and an end face.

[0003] When traditional annular parts are processed by a machining center, the annular workpiece needs to be placed directly on the workbench of the machining center and compressed by means of a pressure plate, a shim, a screw and a nut. The two ends of the pressure plate need to be placed on the annular workpiece and a shim of the same height as the annular workpiece respectively, and the middle part of the pressure plate is bolted to the workbench of the machining center through a screw and a nut for compression. The compression and clamping method of this structure has the following shortcomings: it is difficult to find a shim of the same height as the annular workpiece, and the gaskets of different thicknesses placed on the shim are easy to fall off during clamping; at the same time, when the nut on the pressure plate is connected to the screw, the nut usually needs to be rotated many times to compress the pressure plate, which is time-consuming and labor-intensive. The process of clamping the annular workpiece is extremely troublesome, and the clamping efficiency is low. In addition, the workbench of the traditional machining center is relatively thin. After clamping the workpiece, the whole is prone to slight vibration when the cutting force is large during the cutting process, which affects the machining accuracy. Utility Model Content

[0032] Reference Figures 1 to 9 As shown, one aspect of the present invention provides a vibration-proof platform for processing annular aviation parts, comprising: a bottom beam platform 1, an upper stabilizing platform 2, and a clamp 3.

[0033] Hereinafter, part of the structure and principle of the above components according to the present anti-vibration table will be described in detail.

[0034] As an example, Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 As shown, the bottom beam platform 1 can be made of a casting through machining, the lower part of the bottom beam platform 1 is evenly milled with a T-shaped groove 11, the middle of the upper part of the bottom beam platform 1 is evenly provided with a longitudinal beam 12, both sides of the longitudinal beam 12 are provided with evenly distributed transverse stabilizing beams 13, the longitudinal beams 12 and the transverse stabilizing beams 13 are T-shaped and distributed at 90 degrees; the upper stabilizing platform 2 is placed on the upper part of the bottom beam platform 1 in a bolted connection manner, the upper part of the upper stabilizing platform 2 can be evenly provided with smooth grooves 21, the lower part of the upper stabilizing platform 2 is provided with a raised beam 22, the raised beam 22 of the upper stabilizing platform 2 can be a raised strip-shaped ribbed shape, The raised beam 22 of the upper stabilizing platform 2 can be respectively inserted into the longitudinal beam 12 and the transverse stabilizing beam 13 of the bottom beam platform 1 for clearance fit. The raised beam 22 at the lower part of the upper stabilizing platform 2 and the longitudinal beam 12 and the transverse stabilizing beam 13 at the upper part of the bottom beam platform 1 are inserted into each other in an interlaced manner. Nylon pads can be placed between the raised beam 22 and the longitudinal beam 12 or the transverse stabilizing beam 13. The upper stabilizing platform 2 is connected to the bottom beam platform 1 by bolts and the nylon pads are pressed tightly. The raised beam 22 forms a bite-type connection with the longitudinal beam 12 or the transverse stabilizing beam 13 and the amplitude of the resonance can be offset and reduced by different materials through the clamped nylon pads. The smooth groove 21 of the upper stabilizing platform 2 can adopt a high-finish groove surface. The clamp 3 can be inserted into the smooth groove 21 of the upper stabilizing platform 2 through a T-slot connection method. The clamp 3 is connected to the smooth groove 21 of the upper stabilizing platform 2 in a sliding fit. The clamps 3 are distributed around the upper stabilizing platform 2. The annular workpiece 4 can be quickly clamped by four electrically controlled clamps 3.

[0035] Example 1

[0036] Reference Figures 1 to 5 As shown, the upper stabilizing platform 2 is bolted to the workbench of the machine tool by clamping the bottom beam platform 1. The split design of the upper stabilizing platform 2 and the bottom beam platform 1 can effectively change the amplitude of the resonance amplitude, and the raised beams 22, the longitudinal beams 12 and the transverse stabilizing beams 13 connected in an interlaced manner can enhance the strength of the connection, and can change the force contact surface of the amplitude. The amplitude of the resonance generated during processing and production is reduced by clamping materials with good amplitude elimination properties such as nylon gaskets, and the double-layer design of the upper stabilizing platform 2 and the bottom beam platform 1 can increase the overall strength after being connected to the workbench of the machine tool, thereby avoiding the resonance phenomenon under large cutting force during mechanical processing, and the stability during processing is excellent.

The L-shaped pressure plate 32 can be electrically controlled by the electric drive component 34 to quickly rise or fall. When the L-shaped pressure plate 32 rises or falls, it can be limited by the second tightening body 33 to prevent the L-shaped pressure plate 32 from rotating 360 degrees, thereby ensuring that the L-shaped pressure plate 32 can rise or fall smoothly. After the inner end of the L-shaped pressure plate 32 is placed on the annular workpiece 4, the electric drive component 34 can be used to electrically control the rotation of the second tightening body 33, and the L-shaped pressure plate 32 can firmly press the annular workpiece 4 on the upper stabilizing platform 2 in the form of a nut.

The first lifting body 31 or the second tightening body 33 is driven by its respective electric drive assembly 34, which is connected to the first lifting body 31 or the second tightening body 33 in a gear-speed reduction meshing transmission connection. The electric drive assembly 34 is connected to the first lifting body 31 or the second tightening body 33 in the same manner. The electric drive assembly 34 includes a frame bar base plate 341, a deep groove ball bearing 342, a pressure bearing 343, a dustproof rubber sleeve 344, a gear set 345, and a strong magnetic motor 346. The frame strip base plate 341 is a frame shape formed by welding plates. The frame strip base plate 341 is connected to the transition rod 312 of the first lifting body 31 through the deep groove ball bearing 342 to ensure that the first lifting body 31 can rotate freely. The upper and lower ends of the frame strip base plate 341 are provided with the pressure bearings 343. The pressure bearings 343 are concentrically distributed with the deep groove ball bearings 342. The two upper and lower pressure bearings 343 can be slidably connected with the smooth groove 21. The pressure bearings 343 can be in the The first lifting body 31 can still rotate smoothly when subjected to upward or downward force; the strong magnetic motor 346 and its corresponding controller can rotate the height adjustment gear plate 313 through the speed reduction transmission of the gear set 345, thereby realizing the forward and reverse rotation of the first lifting body 31; the forward and reverse rotation of the first lifting body 31 can realize the raising or lowering of the L-shaped pressure plate 32 by threaded transmission, ensuring that the L-shaped pressure plate 32 can be quickly adjusted to the required height position, and the pressure plate shim can be quickly raised or lowered, which is convenient to use. The exterior of the frame bar base plate 341, the pressure bearing 343, and the gear set 345 are all provided with the dustproof rubber sleeve 344 to prevent foreign matter from entering the bearings or gears. The length between the axis of the first threaded rod 311 and the axis of the strong magnetic motor 346 is greater than or equal to 2 times the minimum groove width of the smooth groove 21. The strong magnetic motor 346 can be placed in the smooth groove 21 for clearance fit. After the strong magnetic motor 346 is started, it can smoothly drive the first threaded rod 311 to rotate.

[0041] Example 4

[0042] As an example, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 8 and Figure 9As shown, the second tightening body 33 is composed of a second threaded rod 331, a hexagonal body 332, a connecting rod 333, and a locking toothed disc 334. The second threaded rod 331, the hexagonal body 332, the connecting rod 333, and the locking toothed disc 334 can be forged parts and can be processed as a single piece. The L-shaped pressure plate 32 is provided with an elongated hole 321, through which the second threaded rod 331 of the second tightening body 33 is inserted for a clearance-fitting sliding connection. When the L-shaped pressure plate 32 is raised or lowered, the second threaded rod 331 is always placed in the elongated hole 321. The rotation of the second threaded rod 331 by the electric drive assembly 34 is driven in the same manner as the first threaded rod 311 and the electric drive assembly 34. The size and module of the locking toothed disc 334 can be exactly the same as those of the height adjustment toothed disc 313. When the L-shaped pressing plate 32 presses the annular workpiece 4, the electric drive assembly 34 electrically controls the rotation of the second threaded rod 331, so that the nut on the second threaded rod 331 is quickly pressed onto the L-shaped pressing plate 32, eliminating the need to manually tighten the nut multiple times, saving time and effort. Furthermore, a wrench can be used to tighten the nut on the nut and the hexagonal body 332, ensuring that the L-shaped pressing plate 32 finally presses the annular workpiece 4. The clamping strength is high, and the annular workpiece 4 is subjected to large cutting forces during processing, making it less prone to vibration. Furthermore, the double-layer bottom beam platform 1 and the upper stabilizing platform 2 have high structural strength and excellent stability. This device is simple in structure, easy to use, and highly practical.
