Abstract

The utility model belongs to the technical field of mechanical tools and relates to a fixture for turning of concave spheres. The fixture for turning of the concave spheres comprises a tool rest, a draw bar and a support. The support is connected with the tool rest through a pin, and particularly, the support and the cutter rest are connected through the pin by the aid of retainer rings. A vertical elongated slot is arranged on the top surface of the tool rest, a side elongated slot is arranged on one side of the tool rest, the draw bar is fixed into the side elongated slot by a connecting pin penetrating through the vertical elongated slot, and the connecting pin is fixed with the draw bar by the aid of a fastening screw. The other end of the tool rest disconnected with the support is provided with a groove, a turning tool is mounted in the groove and clamped by screws, and the draw bar is fixed with a lathe saddle through screws. The fixture is simple in structure, safe in operation, higher in practical value and particularly applicable to batch production.

Description

A kind of concave spherical surface turning clamp
Technical field
The utility model belongs to the machine tool technical field, relates to a kind of concave spherical surface turning clamp.
Background technology
The concave spherical surface turning processing of axial workpiece is general adopts methods such as moulding cutter, pattern, but the moulding cutter is more easy to wear, unsuitable batch machining.Pattern processing can't guarantee machining accuracy again.A kind of to be suitable for the higher again processing method of batch machining, precision necessary so study.
Summary of the invention
The purpose of the utility model is: provide a kind of precision higher, practical concave spherical surface turning clamp.
The technical solution of the utility model is: this concave spherical surface turning clamp includes knife rest, draw bar and bearing.Bearing is connected through bearing pin with knife rest, and bearing pin links together bearing and knife rest through back-up ring, and the knife rest end face has been opened vertical elongated slot; The side elongated slot has also been opened in the knife rest side, and connecting pin passes vertical elongated slot draw bar is fixed in the elongated slot of side, and connecting pin and draw bar are fixed through holding screw; The other end that knife rest is not connected with bearing has groove; Lathe tool is installed in the groove, and lathe tool is through screw in compression, and draw bar and lathe saddle are fixed together through screw.
Advantage of the present invention is:
The utility model is adjusted radius of clean-up through the knife rest of changing different size, to meet the requirements of the concave surface size.Through being installed in the feeding of the connecting rod realization turning on the tool holder.This clamp structure is simple, handling safety, and good practical value is arranged, special suitable batch production.
Description of drawings
Fig. 1 is a structural representation of the present invention, and wherein, 1 is lathe tool, and 2 is knife rest, and 3 is screw, and 4 is vertical elongated slot, and 5 is draw bar, and 6 is screw, and 7 is lathe saddle.
Fig. 2 is a cutaway view of the present invention, and wherein, 8 is groove, and 9 is the side elongated slot, and 10 is connecting pin, and 11 is screw, and 12 is back-up ring, and 13 is bearing pin, and 14 is back-up ring.
The specific embodiment
These anchor clamps include knife rest 2, draw bar 5 and bearing 15.Bearing 15 is connected through bearing pin 13 with knife rest 2; Bearing pin 13 links together bearing 15 and knife rest 2 through back-up ring 12,14, and knife rest 2 end faces have been opened vertical elongated slot 4, and side elongated slot 9 has also been opened in knife rest 2 sides; Connecting pin 10 passes vertical elongated slot 4 draw bar 5 is fixed in the side elongated slot 9; Connecting pin 10 is fixing through holding screw 11 with draw bar 5, and the other end that knife rest 2 is not connected with bearing 15 has groove 8, and lathe tool 1 is installed in the groove 8; Lathe tool 1 compresses through screw 3, and draw bar 5 is fixed together through screw 6 with lathe saddle 7.
The utility model is installed in bearing 15 on the tailstock of lathe and fixes in use, and adjusts the distance of lathe tool 1 and bearing pin 13 through the knife rest 2 of changing different size, to reach the purpose of adjustment concave surface R size.Add the front and back feeding of man-hour through adjustment lathe saddle 7 and make lathe tool 1 produce arc track, and then realize the processing of the recessed R profile of workpiece.
