Detailed Description

As shown in fig. 2, 3 and 4, the machining fixture for the aero-engine rotating part comprises a bottom plate 1 and an L-shaped pressing plate 2, a pressing plate mounting area 11 and a bearing area 12 are arranged at the top of the bottom plate 1, the bearing area 12 is used for bearing a clamping part a formed by bending the bottom of the aero-engine rotating part inwards, a mounting hole 13 is formed in the pressing plate mounting area 11, the mounting hole 13 is used for allowing an assembling rod 21 at the bottom of the pressing plate 2 to extend into, the length of the assembling rod 21 is greater than the thickness of the position of the bottom plate 1 corresponding to the pressing plate mounting area 11, a limiting groove 14 is further formed in the pressing plate mounting area 11, one end of the limiting groove 14 is communicated with the upper part of the bearing area 12, the mounting hole 13 is located in the limiting groove 14, the pressing plate 2 further comprises a pressing block 22 connected with the assembling rod 21, when clamping, the pressing block 22 is pressed on the clamping part, the limiting groove 14 is used for limiting the rotation of the pressing block 22, and the bottom of the assembling rod 21 penetrates through the bottom plate 1 and is provided with threads for connecting the clamping nut 3.

The middle of the bottom plate 1 is also provided with a threaded hole which can be fixed on a machine tool, and with reference to fig. 1 and 2, as a gap is arranged above a part clamping part, when the clamping part is arranged on the bearing area 12, the gap above the part clamping part can be used for the pressing block 22 to extend into, and meanwhile, the length of the assembling rod 21 is greater than the thickness of the position of the bottom plate 1 corresponding to the pressing plate mounting area 11, namely, the length of the assembling rod 21 is not only greater than the distance from the bottom of the pressing plate mounting area 11 in the vertical direction to the bottom of the limiting groove 14, but also greater than the distance from the bottom of the pressing plate mounting area 11 in the vertical direction to the tops of the limiting blocks at two sides of the limiting groove 14, so that the pressing block 22 can completely extend out of the limiting groove by abutting against the assembling rod 21, and then the pressing block can rotate by rotating the assembling rod; the purpose of "one end of the limiting groove 14 is communicated with the upper part of the bearing area 12" is to ensure that the bottom of the pressing block is positioned in the limiting groove 14, and at the same time, the bottom of the pressing block can extend out of the limiting groove to the upper part of the bearing area 12 and can be pressed on the clamping part, and "when the pressing block 22 is pressed on the clamping part, the limiting groove 14 is used for limiting the rotation of the pressing block 22", which means that when the clamping part of the part is positioned on the bearing area, the top end of the pressing plate mounting area 11 is higher than the top end of the clamping part, when the pressing block 22 is pressed on the clamping part, the pressing block 22 is still positioned in the limiting groove 14, in conclusion, when the clamping is needed, the pressing block can be lifted by the assembling rod to be separated from the limiting groove, and then rotates until the pressing block can fall down to indicate that the pressing block falls into the limiting groove again and one end of the pressing block extends out of the limiting groove and can be pressed on the clamping part, so that the clamping can be determined in place without observation, and then clamping can be completed by screwing the clamping nut 3.

Specifically, bottom plate 1 is circular, and load-bearing zone 12 is the outermost end that the annular is located bottom plate 1 top, and clamp plate installing zone 11 is that the annular is located load-bearing zone 12 inboard and adjacent rather than, and spacing groove 14 sets up along bottom plate 1's direction of radius, and spacing groove 14 is greater than one and evenly sets up around the centre of a circle of bottom plate 1, and such structure is the part shape of laminating more, and a plurality of clamp plates 2 can be installed as required to a plurality of spacing grooves 14 simultaneously for the clamping is more stable.

The distance of pilot hole 13 to spacing groove 14 one end is less than the length of briquetting 22, and briquetting 22 can stretch out spacing groove 14 from one end promptly, and the distance of pilot hole 13 to the spacing groove 14 other end is greater than the length of briquetting 22, and is promptly as briquetting 22 towards the other end, and briquetting 22 tip also is located the spacing inslot, and briquetting 22 can dodge the work piece towards the spacing groove 14 other end then when not the clamping like this, also can receive the limiting displacement of spacing groove simultaneously, can not take place to rotate at will.

After adopting above-mentioned structure, when using, combine fig. 3, fig. 4, wherein in fig. 3, fig. 4 left clamp plate 2 is the non-clamping time clamp plate 2 mode of placement, it is towards the spacing groove other end promptly towards bottom plate centre of a circle direction, when needs clamping, make the clamp plate stretch out the spacing groove through the assembly pole and rotate about 180 degrees angles again, readjust suitable position and make it fall and can make the briquetting towards the one end of spacing groove promptly the installation form of clamp plate 2 on right side in the picture, 2 initial position of clamp plate are unified like this, the clamping of being more convenient for.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
