Description

Technical Field

[0001] The present invention relates to the technical field of hole enlarging equipment, and in particular to a hole enlarging equipment and a hole enlarging method. Background Art

[0002] As a high-precision device, the optical system of a spacecraft has the integral flange as one of its key components. The integral flange not only needs to bear the structural support function, but also must meet performance indicators such as lightweight, high rigidity, high strength and low thermal expansion coefficient to ensure the stable operation of the optical system in extreme aerospace environments. The commonly used material for making integral flanges is aluminum-based silicon carbide composite materials, and in order to increase the high rigidity and high strength of the integral flange, the requirements for the silicon carbide reinforcement ratio are relatively high when making the integral flange, which greatly increases the difficulty of the integral flange expansion operation.

[0003] Existing reaming equipment mainly achieves reaming operations by replacing drill bits of different diameters when reaming the flange of a whole machine. Specifically, the reaming equipment needs to frequently replace drill bits for reaming holes of different sizes on the flange of the whole machine, and needs to clamp and position the flange of the whole machine multiple times to complete the reaming operations at different angles of the flange of the whole machine. This not only greatly reduces the reaming efficiency, but also reduces the reaming accuracy due to multiple clamping and positioning of the flange of the whole machine.

[0004] In summary, it is necessary to develop a hole reaming device and a hole reaming method to solve the problem that the existing hole reaming equipment needs to frequently replace the drill bit for hole reaming operations of different sizes of holes on the whole machine flange, resulting in low hole reaming efficiency, and the need to clamp and position the whole machine flange multiple times, resulting in low hole reaming accuracy.

[0072] Step S3, using the hole expansion feeding component 5 to drive the hole expansion positioning component 6 to link the hole expansion operation component to approach the workpiece A; using the hole expansion positioning component 6 to position the hole expansion operation component to the hole expansion position of the workpiece A, and the variable diameter hole expansion operation cavity of the hole expansion operation component drives each blade 9.1.3 to complete the variable diameter hole expansion operation.

[0073] The process of completing the variable diameter expansion operation is as follows:

[0074] According to the specific size of the reaming hole diameter, the PLC controller 15 is used to synchronously control the telescopic operation of the second telescopic driving member 7.4 in the variable diameter reaming operation driving unit in the first reaming operation member 7 and the second reaming operation member 8, and sequentially links the corresponding sleeve structure 7.8 and the connecting rod 7.9 to telescopic movement, thereby driving the corresponding guide block 7.6 to move radially along the radial channel, thereby changing the size of the variable diameter reaming operation cavity surrounded by each of the slots 7.7; wherein, the PLC controller 15 controls the telescopic operation of the second telescopic driving member 7.4 in real time according to the distance data between the sleeve structure 7.8 and the closed end of the second slot body 7.2 monitored by the second distance sensor 11 until the size of the variable diameter reaming operation cavity is adjusted to meet the set reaming requirements;

[0075] The PLC controller 15 then synchronously controls the first rotating drive member 7.3 in the first reaming operation component 7 and the second reaming operation component 8 to drive the second trough body 7.2 to drive the variable diameter reaming operation drive unit to rotate, thereby enabling each blade 9.1.3 to complete the variable diameter reaming operation.
