Problems solved by technology

The axis of the hole is easy to be skewed in deep hole machining. This is because the deep hole tool is thinner, its strength and rigidity are relatively poor, and it is prone to deviation and vibration during processing. In addition, the cooling and heat dissipation conditions of the tool

Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with the examples.

[0014] Such as Figure 1~2 As shown, the guide device for deep hole processing of nuclear power drive tube socket provided by the present invention includes a bushing and a bushing, one end of the bushing is tightly fitted to the workpiece, the other end of the bushing is provided with a bushing, and the contact end surface of the bushing and the workpiece is arranged Oil seal; the drill bit is inserted into the bushing for guiding processing; the shaft sleeve is provided with tightening bolts. The device is fixed on the main shaft of the machine tool when installed. Select the appropriate bushing according to the size of the deep hole of the drive pipe seat to be processed, insert the selected bushing into the bushing, and confirm whether the bushing is installed in place; check whether the oil seal is damaged. After confirming that the oil seal is not damaged, install the bush...

Abstract

The invention relates to a guide device for nuclear power driving pipe seat deep hole machining, which comprises a shaft sleeve and a bush. A workpiece is tightly sheathed at one end of the shaft sleeve. The bush is arranged in the other end of the shaft sleeve. An oil seal is arranged between contact surfaces of the shaft sleeve and the workpiece. A drill bit is inserted into the bush for guide machining. A tightening bolt is arranged on the shaft sleeve. By using the guide device, effective guide can be realized, the problems of deviation and vibration which are apt to occur during machining are solved, the deep hole machining quality and the machining progress are guaranteed, the requirements on product size accuracy and surface roughness are satisfied, the problems of great chip removal difficulty, poor heat dissipation effect and the like are solved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a tooling fixture for deep hole processing of a nuclear power drive pipe seat, in particular to a guide device used in processing the deep hole of a drive pipe seat. Background technique [0002] In the application field of new nuclear power products, deep hole processing is different from general hole processing. Deep hole processing refers to processing where the ratio of the length of the hole to the diameter of the hole is greater than 10. In general deep holes, the depth-to-diameter ratio L / d is greater than or equal to 100 in most cases. Such as the cylinder hole, the axial oil hole of the shaft, the rocket body and the barrel of various artillery, etc. Deep hole processing is difficult and the processing workload is large, which is a key process in mechanical processing. [0003] In order to adapt to the deep hole processing of new engineering materials with more and more types and more and more difficult processing, t...
