Embodiment Construction

[0011] The present invention will be further described below in conjunction with accompanying drawing.

[0012] Referring to the attached picture:

[0013] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0014] A cutter body 1 with a hollow structure is fixed with an internally threaded cylindrical pin 11 and a hexagon socket head screw 12 in front of the tool holder 10; a T-shaped thread connection is used between the cutter body 1 of the hollow structure and the hollow boring bar 15, and the outer circle The end face turning tool 9 is installed on the tool holder 10 with a hexagon socket head cap screw 13 .

[0015] V-shaped blocks 3 and 7 are respectively fixed on the front and rear ends of the outer cylindrical surface of the cutter body 1 of the hollow structure by cylindrical end set screws 6, and the V-shaped grooves formed between the two V-shaped blocks are evenly distributed. 12 adjusting ste...

Abstract

The invention discloses a follow-up supporting tool bit device used for processing a deep hole, which comprises a tool seat and an excircle end face turning tool arranged on the tool seat and is characterized in that a tool body with a hollow structure is fixed in the front of the tool seat; the tool body with the hollow structure is in T-shaped threaded connection with a hollow boring bar; V-shaped blocks are respectively fixed at the front and rear ends of an outer cylindrical surface of the tool body with the hollow structure; 8-16 adjusting steel balls are respectively distributed in V-shaped grooves of the two V-shaped blocks; the adjusting steel balls are externally fixed by a retainer; and a radial locking nut butts against the end face of the V-shaped block and pushes the V-shaped block to move. When the V-shaped block moves, a radial force is generated to the steel ball to adjust the diameter of the outer ring of the steel ball and lead the diameter to be equal to the diameter of an inner hole processed by the excircle end face turning tool. Therefore, the device has the positioning function, the coolant flows through the hollow boring bar and the tool body with the hollow structure and is sprayed out from a coolant hole on the tool body, so that the device has the scrap discharging and cooling function in the hole of a workpiece, and can prevent the iron scraps from scratching the processed surface of the workpiece.

Description

technical field [0001] The invention relates to a follow-up supporting cutter head device for machining deep holes on a lathe. Background technique [0002] At present, when deep holes are processed, a boring machine is mainly used to bore the hole. When the depth of the hole exceeds 1m, the required boring machine is expensive, and the machining accuracy cannot reach the design accuracy because the boring bar is too long. Contents of the invention [0003] The object of the present invention is to provide a follow-up supporting tool head device for machining deep holes on a lathe, so as to improve the precision of machining deep holes and reduce equipment costs. [0004] The technical solution adopted by the present invention is: comprising a tool seat, an outer circular end face turning tool installed on the tool seat, characterized in that a hollow structure cutter body is fixed in front of the tool seat, the hollow structure cutter body and the hollow boring bar There...
