Internally hooking and shaping flexible cutter
Technical field
What the present invention relates to is that a kind of lathe that is used for carries out the molding cutter of machining to workpiece, belongs 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 objective of the invention is to overcome the deficiency that prior art exists, and provide a kind of simple in structure, easy to use and reliable, processing work is clamped and maintains static, and the internally hooking and shaping flexible cutter that the rotation of described molding cutter is rotated.
The objective of the invention is to finish by following technical solution, it mainly is made up of knife bar and the moulding cutter that is installed on the knife bar, and the front end sleeve of described knife bar is equipped with the saddle by pressing the Yellow River pull bar to have moved on knife bar; Described moulding cutter tail end is installed in the oblique chute that is provided with on the knife bar by a sliding pin, and the middle-end of moulding cutter is fixed on the saddle by another sliding pin.
Two avris evenly are provided with two pull bars and use the spring roof pressure on the relative inner face of saddle and knife bar between described saddle and the knife bar.
The outside end face of described saddle is provided with the ball that can compress workpiece or mould.
Molding cutter of the present invention 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 invention.
The specific embodiment
The present invention will be described in detail below in conjunction with accompanying drawing: shown in Figure 1, the present invention mainly is made up of knife bar 1 and the moulding cutter 2 that is installed on the knife bar 1, and the front end sleeve of described knife bar 1 is equipped with the saddle 5 that can move by spring 3 and pull bar 4 on knife bar 1; Described moulding cutter 2 tail ends are installed in the oblique chute 7 that is provided with on the knife bar 1 by a sliding pin 6, and the middle-end of moulding cutter 2 is fixed on the saddle 5 by another sliding pin 8.
Two avris evenly are provided with two pull bars 4 and use spring 3 roof pressures on the relative inner face of saddle 5 and knife bar 1 between saddle 5 shown in the figure and the knife bar 1.The outside end face of described saddle 5 is provided with the ball 9 that can compress workpiece or mould.Knife bar 1 rotates and moves down, and it is motionless that saddle 5 and ball 9 contacts with workpiece, along with knife bar 1 moves down, moves on saddle 5 and ball 9 are relative, drive moulding cutter 2 outwards rotations cut, size reaches cutting effect by the control that moves up and down.
