Embodiment approach 1

[0019] Such as figure 1 , figure 2 , image 3 As shown, the workpiece 7 of the present invention rotates, and the deep hole cutter 9 feeds. Bottom hole is arranged on workpiece 7, needs the deep hole of boring axis level.

[0020] The present invention comprises deep hole tool 9, cutter bar 13, main shaft box 1, main shaft 2, expansion sleeve 3, fastening nut 4, core sleeve 5, holder 6, fastening screw 8, metal block 10, corner pyramid prism support Seat 11, corner cube prism 12, center frame 14, laser emitting device 15, photosensitive sensor 16, computer 17, cutter bar support 18, sliding plate 19, machine bed 20, wear-resistant and heat-resistant block 21, heating device 22, outer rack 23, laser orientation block 24, etc. Through the rotation of the workpiece 7, the deep hole tool 9 is fed to process the deep hole; one end of the workpiece 7 is clamped and positioned by the clamper 6, and the other end is supported by the center frame 14, which is driven to rotate by t...

Embodiment approach 2

[0023] In the second embodiment, there is no bottom hole on the workpiece 7, and a deep hole with a horizontal axis needs to be processed. In this case, the non-expansion sleeve 3, fastening nut 4, and core sleeve 5 of the present invention are the same as the first embodiment.

Abstract

The invention belongs to the technical field of deep-hole machining and particularly relates to a deep-hole machining online deviation rectifying device based on the laser detection principle. The problem that real-time straightness detection and deviation rectification are difficult in an existing deep-hole machining process is solved. The deep-hole machining online deviation rectifying device comprises a deep-hole cutter and a cutter rod. A laser orientation block, a cube-corner prism support, the deep-hole cutter and a metal block internally provided with a heating device are mounted on the cutter rod. Light beams emitted by a laser emitting device enter in parallel with the axis of the cutter rod after being oriented through the laser orientation block, and after passing through a cube-corner prism, the light beams form return light beams arriving at a photosensitive sensor. The deep-hole machining online deviation rectifying device has the beneficial effects that deviation of the deep-hole cutter can be examined in time and rectified according to the thermal expansion and cold shrinkage principle, and the straightness and positional accuracy of a machined deep hole are improved.

Description

technical field [0001] The invention belongs to the technical field of deep hole processing, and in particular relates to an "on-line deviation correction device for deep hole processing based on the principle of laser detection". Background technique [0002] The so-called deep hole is the hole whose length to diameter ratio is greater than 5, such as hollow spindle hole and hydraulic valve hole and so on. Among these holes, some require high machining accuracy and surface quality, and some of the processed materials have poor machinability. During the processing of deep holes, personnel cannot directly observe the processing part and the cutting condition of the tool, but can only listen to the sound during cutting, observe the chip shape, touch the vibration condition and workpiece temperature, and observe the instrument (oil pressure gauge and electric meter) , Use work experience to judge whether the cutting process is normal. None of the above methods can measure the...
