Abstract

The utility model relates to an outer hook molding telescopic cutter which mainly comprises a cutter rod, a cutter rest and a molding cutter, wherein an inner cavity body of the cutter rod is provided with the cutter rest which can extend and retract in the inner cavity body by a pressing spring supporting and pressing the inner end surface of a sub-cutter rod ; the cutter rest is provided with the molding cutter on which one end part is fixed at the cutter rest, the upper side surface is clung to the wall surface of the inner cavity body and the front end part extends out of the inner cavity body and inclines outward; the side wall of the cutter rest is provided with a section of limiting groove, and an upper limiting bolt and a lower limiting bolt are fixed on the side wall of the inner cavity body of the cutter rod according to the upper positions and the lower positions and extend into the limiting groove; the front end surface of the cutter rest is provided with a plane bearing capable of being tightly adhered to the end surface of a workpiece and also provided with a limiting head; and a spring supported and pressed between the cutter rest and the molding cutter is also arranged between the cutter rest and the molding cutter. The outer hook molding telescopic cutter is characterized by simple structure, convenient and reliable use, high processing efficiency, good processing quality and the like.

Description

Outer hooking and shaping flexible cutter

Technical field

The utility model relates to a kind of lathe that is used for workpiece is carried out the molding cutter of machining, belong to a kind of tool for mechanical machining.

Background technology

The cutter that adopts in the mechanical processing process is aligned cutting tool or the many fixedly compound tool that bite is formed that is fixed on the lathe at present.In mechanical processing process, general cutter maintains static, and workpiece rotates the purpose that reaches machining; But if processing work product big or eccentric design needs large-scale machining equipment.

Summary of the invention

The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of simple in structure, and is easy to use and reliable, and processing work is clamped and maintains static, and the outer hooking and shaping flexible cutter that the rotation of described molding cutter is rotated.

The purpose of this utility model is finished by following technical solution, it mainly is made up of knife bar, knife rest and moulding cutter, one knife rest that can stretch in inner chamber body in knife bar inner face stage clip by a roof pressure is installed in the inner chamber body of described knife bar, an end is installed on this knife rest is fixed in the moulding cutter that knife rest, upper side are close to the inner chamber body wall, leading section stretches out outside inner chamber body and tilt laterally.

Offer one section limited impression on the described knife rest sidewall, two caging bolts are fixed on the knife bar inner chamber body sidewall according to upper-lower position and stretch in described limited impression up and down.

Described knife rest front end face is provided with the plane bearing that can be close to workpiece end face.

Also be provided with a spacing head on the front end face of described knife rest; Also be provided with the spring of a roof pressure between knife rest and moulding cutter between described knife rest and the moulding cutter.

Molding cutter described in the utility model can supportingly be used for the lathe of common specification (radius of gyration is not more than 200mm) just can process eccentric product that designs and machining tolerance in 0.05mm, and surface roughness is lower than Ra3.2; Have simple in structure, easy to use and reliable, the efficient height of processing, characteristics such as crudy is good.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in detail: shown in Figure 1, the utility model mainly is made up of knife bar 1, knife rest 2 and moulding cutter 3, one knife rest 2 that can stretch in inner chamber body in knife bar inner face stage clip 4 by a roof pressure is installed in the inner chamber body of described knife bar 1, an end is installed on this knife rest 2 is fixed in the moulding cutter 3 that knife rest 2, upper side are close to the inner chamber body wall, leading section stretches out outside inner chamber body and tilt laterally.

Offer one section limited impression 5 on knife rest 2 sidewalls shown in the figure, two caging bolts 6 are fixed on the knife bar 1 inner chamber body sidewall according to upper-lower position and stretch in described limited impression 5 up and down.

Described knife rest 2 front end faces are provided with the plane bearing 7 that can be close to workpiece end face.

Also be provided with one spacing 8 on the front end face of described knife rest 2; Also be provided with the spring 9 of a roof pressure between knife rest 2 and moulding cutter 3 between described knife rest 2 and the moulding cutter 3.

During use, plane bearing 7 contacts with workpiece end face, along with the rotation of knife bar 1, because of the motionless knife rest 2 of workpiece, plane bearing 7 rotate relative to workpiece, along with moving down of knife bar 1, moulding cutter 3 inwardly rotates cutting under the effect of knife bar 1, size reaches cutting effect by the control that moves up and down.This cutter is applicable to equipment such as engine lathe, common driller, drilling and milling machine, biaxial plane, multiaxis compounding machine.
