Abstract
The utility model relates to a numerical control turning clamp for the outer contour of a focusing guide ring, and the numerical control turning clamp is formed by a clamp body, an expansion taper sleeve, and a set screw, an opening expansion shaft is made at one end of the clamp body, a workpiece positioning step is made at the outer surface of the opening expansion shaft, and the expansion taper sleeve is coaxially installed in the internal of the opening expansion shaft via the set screw. The numerical control turning clamp is advantageous in that, structure is simple, design is reasonable, according to the structural characteristic of the focusing guide ring, the clamp body with the opening expansion shaft is used for clamping, When the screw is set, the clamp body uniformly expands the guide ring under the effect of the expansion taper sleeve, guaranteeing reliable clamping, a part uniformly bears outward radial force for clamping, with machining of an inner hole with phi26mm and the left end surface as the positioning basis, a hole shaft realizes good clearance fit, via one-time clamping, machining of surfaces of the outer contour can be completed, realization processes are concentrated, and form-position precision, size precision and precision stability are guaranteed.
Description
Technical field
The utility model relates to a kind of surveying instrument processing unit (plant) field, especially a kind of focusing guide ring outline numerical control turning clamp for machining.
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, size and accuracy of form and position height, each surperficial accuracy of form and position of particularly inside and outside profile is very high, axiality will be controlled at ± 0.01mm in, the dimensional tolerance of length is 0.01mm.Because the focusing guide ring 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.
Summary of the invention
The purpose of the utility model is to provide a kind of clamping reliable, is easy to processing, guarantees the focusing guide ring outline numerical control turning clamp for machining of product precision.
It is to adopt following technical scheme to realize that the utility model solves its technical problem:
A kind of focusing guide ring outline numerical control turning clamp for machining; It is characterized in that: constitute by clamp body, expansion tapered sleeve and holding screw; One end of clamp body is shaped on the bloated axle of opening; Outer surface at the bloated axle of opening is shaped on the workpiece positioning step, passes through the coaxial installation expansion of holding screw tapered sleeve in the inside of the bloated axle of opening.
And, being shaped on and the consistent cone tank of tapered sleeve tapering that expands in the inside of the bloated axle of opening, the swelling of expansion tapered sleeve is installed in this cone tank.
And the tapering of described cone tank is 15 °.
Advantage of the utility model and beneficial effect are:
The utility model is simple in structure, and is reasonable in design, according to the design feature of focusing guide ring; The clamp body that employing is shaped on the bloated axle of opening carries out clamping, and when holding screw, clamp body is even swelling guide ring under the effect of expansion tapered sleeve; Guarantee that its clamping is reliable, part evenly bears outside radial load and clamps, and is positioning reference with endoporus and the left side that processes Φ 26mm; The hole axle is realized good matched in clearance; Can accomplish each surperficial processing of exterior contour through a clamping, realize that operation is concentrated, guarantee its accuracy of form and position, dimensional accuracy and precision stability.
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.
A kind of focusing guide ring outline numerical control turning clamp for machining; It is made up of clamp body 2, expansion tapered sleeve 4 and holding screw 5; One end of clamp body is shaped on the bloated axle 7 of opening; Outer surface at the bloated axle of opening is shaped on workpiece positioning step 8, passes through the coaxial installation expansion of holding screw tapered sleeve in the inside of the bloated axle of opening.Inside at the bloated axle of opening is shaped on the cone tank 6 consistent with the tapered sleeve tapering that expands, and this tapering is preferably 15 °.Expansion tapered sleeve tensioner is installed in this cone tank.Experiment showed, that the bloated axle of opening and the tapering of expansion tapered sleeve can guarantee enough clamping forces, when unclamping screw, the expansion tapered sleeve unclamps automatically, conveniently takes off workpiece.
The operation principle of the utility model is:
The opening that part 3 the is sleeved on clamp body axle that expands is outside, and the part end is positioned on the workpiece positioning table, adopts holding screw to be installed in opening the expansion tapered sleeve and expands in the axle, realizes the expansion of axle of expanding of expansion tapered sleeve pairs of openings through holding screw, and then workpiece is clamped.The other end clamping of clamp body is on scroll chuck 1.These anchor clamps are adding man-hour, and part evenly bears outside radial load and clamps, and are positioning reference with endoporus and the left side that processes Φ 26mm, and the hole axle is realized good matched in clearance, can accomplish each surperficial processing of exterior contour through a clamping.
