Abstract
The invention relates to a boring bar structure, in particular to a boring bar structure applicable to a numerical control knife turret of a vertical lathe, and belongs to the technical field of vertical lathes. The boring bar structure of the numerical control knife turret comprises a rotary turret knife rest, wherein a dovetail groove is formed in the rotary turret knife rest; a tool holder, a pressing block and a bayonet lock are sequentially arranged inside the dovetail groove from left to right. A bayonet lock clamping face is arranged at the connection position of the bayonet lock and the pressing block, and the connection position of the pressing block and the bayonet lock is provided with a pressing block clamping face matched with the bayonet lock clamping face. The tool holder and the pressing block are connected through a tightening bolt, and the upper end of the tightening bolt penetrates through a through hole in the tool holder and is connected with a threaded hole in the pressing block. The rear end of the tool holder is connected with a boring bar through a bolt. The boring bar structure of the numerical control knife turret is simple, compact and reasonable in structure, convenient to use, and easy and rapid to assemble and disassemble, and improves the working efficiency.
Description
Technical field
The present invention relates to a kind of boring bar, a kind of boring bar that is applicable to vertical car numerical control cutter tower, belongs to vertical car technical field specifically.
Background technology
In vertical lathe, often need to carry out some parts with deep hole of boring with vertical car.The boring bar bore hole dismounting of using at present inconvenience very.In view of the problem of above-mentioned existence, in the urgent need to developing a kind of boring bar of novel numerical control cutter tower.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thereby a kind of boring bar of numerical control cutter tower simple in structure, ingenious, rational is provided, easy accessibility, has improved operating efficiency.
According to technical scheme provided by the invention, the boring bar of numerical control cutter tower comprises turret, connects ram on turret, it is characterized in that: on turret, be provided with dovetail groove, be from left to right provided with successively tool holder, briquetting and bayonet lock in dovetail groove.Bayonet lock and briquetting junction are provided with bayonet lock clamping face, and briquetting is provided with bayonet lock junction the briquetting clamping face matching with bayonet lock clamping face.Described tool holder is connected by tighting a bolt with briquetting, and the upper end that tights a bolt is connected with the screwed hole on briquetting through the through hole on tool holder.Tool holder rear end is bolted boring cutter bar.
Further, tool holder is provided with dovetail groove junction the tool holder dovetail portion (6) matching with dovetail groove.
Further, bayonet lock is provided with dovetail groove junction the bayonet lock dovetail portion matching with dovetail groove.
Further, bayonet lock clamping face is inclined-plane.
Compared with the prior art the present invention has the following advantages:
The present invention is simple in structure, compact, reasonable, and easy to use, dismounting is simple and quick, has improved operating efficiency.

Description of reference numerals: 1-ram, 2-turret, 3-dovetail groove, 4-tool holder, 5-boring cutter bar, 6-tool holder dovetail portion, 7-tight a bolt, 8-bayonet lock, 9-bayonet lock clamping face, 10-bayonet lock dovetail portion, 11-briquetting, 12-briquetting clamping face.
The specific embodiment
The present invention is below further described in connection with the embodiment in accompanying drawing:
As shown in Figure 1 and 2, the present invention mainly comprises turret 1, connects ram 1 on turret 1.On turret 1, be provided with dovetail groove 3, in dovetail groove 3, be from left to right provided with successively tool holder 4, briquetting 11 and bayonet lock 8.
Described tool holder 4 is provided with dovetail groove 3 junctions the tool holder dovetail portion 6 matching with dovetail groove 3.
Described bayonet lock 8 is provided with dovetail groove 3 junctions the bayonet lock dovetail portion 10 matching with dovetail groove 3, and bayonet lock 8 is provided with bayonet lock clamping face 9 with briquetting 11 junctions, and bayonet lock clamping face 9 is inclined-plane.Described briquetting 11 is provided with bayonet lock 8 junctions the briquetting clamping face 12 matching with bayonet lock clamping face 9.
Described tool holder 4 and briquetting 11 are by 7 connections that tight a bolt, and 7 upper ends that tight a bolt are connected with the screwed hole on briquetting 11 through the through hole on tool holder 4.
Tool holder 4 rear ends are bolted boring cutter bar 5.
Operation principle of the present invention is: during work, by rotation, tight a bolt 7, regulate the position of briquetting 11, briquetting 11 clamps the tight face 9 of face 12 push card pin card by briquetting, thereby regulate tool holder 4, briquetting 11 and the clamping level of bayonet lock 8 in dovetail groove 3, thereby carry out easily installation or removal.
