Abstract

The utility model relates to a numerical control turning fixture for the inner outline of a focusing guide ring. The fixture consists of a fixture body and a threaded clamping sleeve, wherein the fixture body is cylindrical; a workpiece ring groove is formed on the inner wall of the fixture body; the radial depth of the ring groove is smaller than the wall thickness of a workpiece; an external thread is formed and the threaded clamping sleeve is arranged on the outer wall of the same end of the fixture body; and a workpiece positioning step is formed on the outer end face of the threaded clamping sleeve. The fixture has a simple structure and is reasonable in design, a part is placed into the workpiece ring groove formed in the fixture body and is positioned and clamped by the threaded clamping sleeve at the end, the end face and the outer cylindrical surface of the part are positioned, the part completely bears axial force when clamped, and axial rigidity is high. The fixture is easy to operate, reliably positions and clamps the part, can clamp a plurality of parts simultaneously, and is finished through one-time processing, production efficiency is greatly improved, the processing quality of products is ensured, and considerable economic benefits are created for enterprises.

Description

Profile numerical control turning clamp for machining in the focusing guide ring
Technical field
The utility model relates to a kind of surveying instrument processing unit (plant) field, profile numerical control turning clamp for machining in especially a kind of focusing guide ring.
Background technology
The high accuracy surveying instrument is the indispensable precision instrument of geological prospecting, is directly connected to actual surveying accuracy, and especially its critical component focusing guide ring has the high accuracy of manufacture.Correct Technology for Heating Processing and manufacturing process are the high-precision basic assurances of focusing guide ring.Because the focusing guide ring requires surface quality high; The size and the accuracy of form and position are high; And it belongs to thin-wall part, is easy to generate internal stress and cutting deformation; Therefore adopt common truning fixture and anchor clamps to have big difficulty of processing, Bao Bi very easily produces distortion in clamping and process, and the product precision is difficult to guarantee.
Existing thin ancient piece of jade, round, flat and with a hole in its centre spare is to utilize to crack to pack into the luggage folder, and this installation way simplicity of design is easy to make, uses flexibly, and it is big to clamp contact area, makes part stress even, can prevent to crush piece surface.But these anchor clamps make part receive radial load in clamping process, and workpiece can produce micro-deformation, are not suitable for the processing of high-precision part; And clamping force is big inadequately; Occur the knife phenomenon easily, produce the uniformity that is difficult to guarantee clamping in batches, can not satisfy the specification requirement of this product.
The utility model content
The purpose of the utility model is to provide a kind of clamping reliable, is easy to processing, guarantees the interior profile numerical control turning clamp for machining of focusing guide ring of product precision.
It is to adopt following technical scheme to realize that the utility model solves its technical problem:
Profile numerical control turning clamp for machining in a kind of focusing guide ring; It is characterized in that: constitute by clamp body and screw thread gripping sleeve; Clamp body is a cylindrical shape, is shaped on the workpiece annular groove at the inwall of clamp body, and the radial depth of this annular groove is less than workpiece; Outer wall in the same end of clamp body is shaped on external screw thread and the screw thread gripping sleeve is installed, and the outer face of this screw thread gripping sleeve is shaped on workpiece location stage.
And, also comprising a part shading ring, this part shading ring is inlaid in the made workpiece annular groove of clamp body, and the thickness of part shading ring is less than the part wall thickness.
And, on the cylindrical of screw thread gripping sleeve, be uniformly distributed with and be shaped on four radially cylindrical holes.
Advantage of the utility model and beneficial effect are:
1. profile numerical control turning clamp for machining in this focusing guide ring; Workpiece is positioned in the workpiece annular groove made in the clamp body; The end adopts the screw thread gripping sleeve to realize the location of part is clamped; End face and external cylindrical surface with part position, and clamp body adopts the axial force end face to clamp, and significantly reduces the distortion and the positioning accuracy of part.
2. profile numerical control turning clamp for machining in this focusing guide ring, two parts of clamping simultaneously in the clamp body, thus can process two parts simultaneously, significantly reduce overhead time, improved efficient.
3. profile numerical control turning clamp for machining in this focusing guide ring is shaped on four cylindrical holes radially on the gripping sleeve cylindrical, is rotated through in the hole, inserting major axis, can realize stepping up fast and unclamping workpiece, reaches efficient operation.
4. the utility model is simple in structure, and is reasonable in design, simple to operate, location and reliable clamping, and can realize many clampings simultaneously, and process at one time, enhance productivity greatly, guarantee the crudy of product, for enterprise creates considerable economic benefit.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explain.
Profile numerical control turning clamp for machining in a kind of focusing guide ring; Its innovation part is: be made up of clamp body 2 and screw thread gripping sleeve 6; Clamp body is a cylindrical shape, is shaped on workpiece annular groove 8 at clamp body one end inwall, and the radial depth of this annular groove is less than workpiece; Outer wall in the same end of clamp body is shaped on external screw thread and the screw thread gripping sleeve is installed, and the outer face of this screw thread gripping sleeve is shaped on workpiece location stage 7.On screw thread gripping sleeve cylindrical, be uniformly distributed with and be shaped on four radially cylindrical holes 9, be rotated, can realize clamping fast and unclamping workpiece, reach efficient operation through in cylindrical hole, inserting major axis.
The operation principle of the utility model is:
Part 3 is positioned in the workpiece annular groove made in the clamp body, and the end adopts the screw thread gripping sleeve to realize the location of part is clamped, and the other end of clamp body is installed in the scroll chuck 1.With the end face and the outside cylinder location of part, part clamps and bears axial force fully, and axial stiffness is good, and this method is simple to operate, location and reliable clamping.And, a plurality of parts 5 are put into clamp body, adopt shading ring 4 to separate between the part, can realize many clampings simultaneously, process at one time, enhance productivity greatly, guarantee the crudy of product, reduce production costs.
