Description

Technical Field

[0001] This invention relates to the field of aero-engine manufacturing technology, and more specifically to a shot peening simulation test piece fixing device for aero-engine parts. Background Technology

[0002] Shot peening is the process of spraying a large number of shot onto the surface of a part, much like countless small hammers striking the surface of the part, causing extremely strong plastic deformation and producing a cold-worked layer of a certain thickness, known as a surface strengthening layer. Therefore, shot peening is a type of surface strengthening process.

[0003] A shot peening simulation fixture is used in conjunction with a shot peening fixture and is an essential fixture device before the actual shot peening of parts. The shot peening simulation fixture is used to simulate the simulated state of parts during shot peening. Its main function is to place the "simulation test piece" at the location of the part to be shot peened for pre-shot peening test, and to obtain and adjust the parameters for the actual shot peening by testing the "simulation test piece".

[0004] In summary, each part requires a dedicated shot peening simulation fixture to debug the parameters of the "simulation test piece" before formal shot peening. The design and manufacturing cycle of a dedicated shot peening simulation fixture is lengthy and costly. Furthermore, the dedicated shot peening simulation fixture can only be used for a single corresponding part and cannot be reused. Given the current trend of diversified and small-batch R&D and trial production of product parts, this is extremely detrimental to cost reduction, efficiency improvement, and cost saving. Summary of the Invention

[0024] In one embodiment of the present invention, the base 1 includes a circular base located in the central region, and a plurality of first T-shaped grooves are evenly arranged circumferentially around the circular base. Preferably, in this embodiment, the number of first T-shaped grooves is four, and correspondingly, the number of the first set of columns and the number of the second set of columns are two each.

[0025] In practice, for ease of processing, the circular base is integrally formed with multiple first T-slots to form the base 1.

[0026] In one embodiment of the present invention, to facilitate the movement and operation of the clamping device, handles 8 are fixedly installed at a set of symmetrical positions on the edge of the circular base, allowing for handling and other operations of the device via the handles 8. Specifically, the handles 8 are fixedly installed on the edge of the circular base using hexagonal socket screws 9.

Therefore, length markings are respectively provided on the edges of the openings of the first T-slot and the second T-slot to achieve precise adjustment.

[0028] Practical experience has proven that the shot peening simulation specimen fixing device of this embodiment fully meets the user's requirements and achieves the pre-set goals.

Height, radial direction, and angle are all adjustable, and the adjustment accuracy of the clamping block position is within ±0.2mm. Within its application range, it can replace more than 90% of existing dedicated simulation fixtures and tooling.

The sliding support 3 includes a vertically connected fixing plate and a connecting plate. The fixing plate is slidably connected to the second T-slot via the T-slot bolt assembly 7, and the connecting plate is rotatably connected to the rotating support 4 via a rotating shaft 10. The shot peening simulation test piece is fixedly mounted on the test piece placement seat 5 using round-head screws 6.

[0031] The simulated test piece fixture device for shot peening integral bladed disks and blade rings of aero engines, as described in this embodiment of the invention, includes several parts such as a base, columns, sliding supports, rotating supports, a test piece placement seat, a handle, and fasteners. The base is the basic foundation of the entire universal device, responsible for supporting all mechanisms and components. Its upper surface has T-slots in four directions, allowing the device to be adjusted along the direction of the slots. The slot edges are marked with length lines to identify the actual specific position of the support adjustment. The four columns are placed within the four T-slots on the base, allowing for...

Specimen placement seats are provided on both the two sliding supports and the two rotating supports, with four screws on each seat for securing the simulated specimen. The fasteners include screws, pins, locking screws, etc., used for connecting and securing the components.

[0032] The method of using the fixture device for placing the simulated test piece according to the embodiment of the present invention is as follows: 1. First, determine the number of simulation test pieces needed before shot peening based on the number of different surfaces that need to be inspected during shot peening of the product parts. Then, determine the spatial position, including angle, of the corresponding simulation test pieces based on the relative positions of the inspection surfaces in the shot peening equipment during the actual shot peening process. This step can serve as a prerequisite input for the fixture device used to place the simulation test pieces. If necessary, simplified drawings can be provided to facilitate subsequent debugging operations.

[0033] 2. Based on the previously determined number, spatial dimensions, and angles of the simulated specimens, perform adjustments on the fixture where the simulated specimens are placed. By adjusting the column's radial sliding within the T-slot on the base, the radial position of the simulated specimen can be accurately determined using the graduations on the T-slot. By adjusting the sliding support's up-and-down movement along the T-slot on the column, the vertical position of the simulated specimen can be accurately determined using the graduations on the column.

[0034] 3. Two of the columns have sliding supports with rotating supports on top of them. The rotating supports can be rotated to any angle. Both the sliding and rotating supports have specimen placement seats, which are secured to the specimens using four screws.

Moreover, the simulation test piece fixing device of this invention is simple and convenient to operate, greatly improving the efficiency of design and manufacturing cycles. Repeated recycling can greatly improve economic benefits and save costs in the product development stage.
