Embodiment 1

[0029] A method for improving the machining accuracy of an aluminum alloy thin-walled part used for a gyroscope frame, the specific steps are as follows:

[0030] Step 1) Rough machining of the part body;

[0031] Step 2) Perform the first heat treatment on the part body; the first heat treatment adopts solution aging heat treatment;

[0032] Step 3) Semi-finishing the part body;

[0033] Step 4) Carry out the second heat treatment on the part body; the second heat treatment adopts the intermediate heat treatment of two cycles of cold and heat;

[0034] Step 5) Connect the process reinforcing rib to the pressing surface of the part body;

[0035] Step 6) Finishing before surface finishing;

[0036] Step 7) Carry out the third heat treatment on the part body, and the third heat treatment adopts solution aging heat treatment;

[0037] Step 8) Finishing of final finished dimensions after surface finishing;

[0038] Step 9) Remove process ribs.

Embodiment 2

[0040] A method for improving the machining accuracy of an aluminum alloy thin-walled part used for a gyroscope frame, the specific steps are as follows:

[0041] Step 1) Rough machining of the part body; 1) Turning of the upper part, lower part, positioning outer circle, and positioning end face of the part body 1; 2) Milling of the machining center to complete the bearing fitting hole, bearing positioning surface, connecting hole, and torque motor The rough machining of the size of the hole and the positioning surface of the torque motor removes a large machining allowance.

[0042] Step 2) Carry out the first heat treatment on the part body; the first heat treatment adopts solution aging heat treatment; first clean the surface of the part body to make the surface free of chips, and then heat the part body in a constant temperature box to a temperature of 90 °C and keep it warm After 3 h, it was then air cooled to room temperature.

[0043] Step 3) Semi-finishing the part b...

Embodiment 3

[0051] Such as figure 1 As shown, the aluminum alloy thin-walled parts used for the gyro frame are prior art, and it includes a part body 1, and the described part body at least includes: a bearing fitting hole 2, a torque motor hole 13, a screw 9, a positioning outer circle 12, The positioning end surface 10, the bearing matching hole 2 is smaller than the torque motor hole 13, and is distributed on the upper part 5 of the part body 1, coaxial with the a-axis 16, and symmetrical with the b-axis 6, the positioning outer circle 12, and the positioning end surface 10 are on the processing body 1 The lower part 11 , the upper part 5 of the part body 1 and the lower part 11 of the part body 1 are connected by ribs 7 and by screws 9 .

[0052] The specific steps of the method for improving the processing accuracy of the aluminum alloy thin-walled parts used for the gyro frame of the present invention are as follows: step 1) rough machining the part body; 1) upper part 5, lower part...

Abstract

The invention relates to a method for improving the machining precision of an aluminum alloy thin-wall part used for a gyroscope frame. The method comprises the specific steps that firstly, a part body is roughly machined; secondly, the part body is subject to first-time heat treatment, and solid-solution aging treatment is adopted in the first-time heat treatment; thirdly, the part body is subject to semi-finish machining; fourthly, the part body is subject to second-time heat treatment, and middle heat treatment of the cold and hot two cycles is adopted in the second-time heat treatment; fifthly, process reinforcing ribs are connected to the compressing face of the part body; sixthly, finishing before surface finish is carried out; seventhly, the part body is subject to third-time heat treatment, and solid-solution aging heat treatment is adopted in the third-time heat treatment; eighthly, finishing of the final size after the surface finish is carried out; and ninthly, the process reinforcing ribs are dismounted. Through the method, the machining quality of the aluminum alloy thin-wall part used for the gyroscope frame can be ensured, the waste caused by unqualified machining is avoided, and the cost is greatly saved.

Description

technical field [0001] The invention relates to a processing method, in particular to a method for improving the processing accuracy of an aluminum alloy thin-walled part used for a gyroscope frame. It belongs to the field of mechanical processing. Background technique [0002] The use of aluminum alloy has good appearance, light weight, good toughness and plasticity, and can be quenched. During aging treatment, the alloy can be strengthened with high strength and high wear resistance. It is widely used in the gyro frame in the field of seeker products. Aluminum alloy thin-walled parts. [0003] This kind of aluminum alloy thin-walled parts used in the gyro frame requires high machining accuracy, but due to the poor rigidity of this kind of parts, it is difficult to control the accuracy during processing. The main performance is that the thin-walled parts have large deformation, the upper and lower parts of the parts are supported by only three ribs, and the rigidity is po...
