Abstract

The utility model relates to an expanding clamp for cylindrical workpiece. There is a blind hole in a clamping device, and one end of it inwardly extends to form a thread hole and the other end outwardly extends to make up an internal conic surface. The tightly swelled side outside the clamp device equips with the interior surface of the work piece. The interior of the blind hole is furnished with a guide way and the guide way mainly comprises a guide face and an outer cone. The external diameter of the guide face is co-operating with the bore diameter of the blind hole. The outer cone is co-operating with the inner cone and a through hole is opened in the guide way. The size of the through hole inside the guide way is in accordance with the size of the external diameter of a screw. The beneficial effect of the utility model is that the minor diameter of integral key and integral key is processed at one time on the ground of the process of interior integral key. The expanding clamp for original integral key is changed into a round column expanding clamp and integrated with the clamp device at one-step refining. The guide face is increased in the clamping device in consideration of the deviation of the expansion force. The guide face and the pyramidal face is one-step refining. A plain screw is used as a draw rod to separate the expansion force and the pulling force and eliminate the deviation of the expansion force.

Description

The cylinder outer race folder that rises

Technical field

The utility model relates to Workpiece clamping device, especially a kind of cylinder outer race folder that rises.

Background technology

According to the technological requirement of company, need process to foreign round as locating surface with internal spline the cartridge type shell of DO type, requiring axiality is in the 0.1mm.Originally the folder that rises of usefulness is to have external splines stamen rod 3 to be contained on the anchor clamps 2 by one as shown in Figure 1, by a conical surface screw 4 folder that rises because that external splines stamen rod 3 is processed is cumbersome, be installed to clamp body 2 after, just have the axiality of 0.03-0.05mm; The male cone (strobilus masculinus) and the external screw thread of adding conical surface screw 4 are not that time processing forms, and have a tension deviation, so product quality is difficult to be controlled in the tolerance.

Summary of the invention

The purpose of this utility model is to provide a kind of cylinder outer race that can effectively control axiality folder that rises.

The technical scheme that its technical problem that solves the utility model adopts.This cylinder outer race folder that rises has blind hole in clamp body, the one end formation screwed hole that extends internally, the other end formation inner conical surface that stretches out, and the tensioner face outside the clamp body end matches with the inner surface on the workpiece; Guide way is installed in the blind hole, and guide way mainly comprises spigot surface and male cone (strobilus masculinus), and the external diameter of spigot surface matches with the internal diameter of blind hole, and male cone (strobilus masculinus) matches with inner conical surface, has through hole in the guide way; The size of the size of guide way inner via hole and screw external diameter adapts, and the external screw thread of screw matches with the internal thread of screwed hole.

The effect that the utility model is useful is: add man-hour according to internal spline, the path of spline and spline time processing form, and the original spline folder that rises is made into the cylinder folder that rises, and be made of one with clamp body, time processing forms, and beating of 0.03-0.05mm originally just is eliminated.Consider the tension deviation, increase spigot surface in anchor clamps, spigot surface becomes with conical surface time processing, makes pull bar with a normal screws, and tension and pulling force are separated, and has avoided the deviation of tension.

Description of reference numerals: workpiece 1, clamp body 2, blind hole 2-1, screwed hole 2-2, inner conical surface 2-3, tensioner face 2-4, external splines plug 3, conical screw 4, guide way 5, spigot surface 5-1, male cone (strobilus masculinus) 5-2, through hole 5-3, screw 6, external screw thread 6-1;

The specific embodiment

Below in conjunction with embodiment and accompanying drawing the utility model is further described.As shown in Figure 2, this cylinder outer race folder that rises has blind hole 2-1 in the described clamp body 2, the one end extends internally and forms screwed hole 2-2, the other end stretches out and constitutes inner conical surface 2-3, and the tensioner face 2-4 of clamp body 2 ends is an external splines, and external splines matches with the internal spline surface on the workpiece 1.Guide way 5 is installed in the blind hole 2-1, and guide way 5 mainly comprises spigot surface 5-1 and male cone (strobilus masculinus) 5-2, and the external diameter of spigot surface 5-1 matches with the internal diameter of blind hole 2-1, and male cone (strobilus masculinus) 5-2 matches with inner conical surface 2-3, has through hole 5-3 in the guide way 5.The size of the size of guide way 5 inner via hole 5-3 and screw 6 external diameters adapts, and the external screw thread 6-1 of screw 6 matches with the internal thread of screwed hole 2-2.

The concrete use: will work 1 is sleeved on the clamp body 2 the surperficial tight fit of the internal spline on its tensioner face 2-4 and the workpiece 1; Guide way 5 is installed among the blind hole 2-1 of clamp body 2 its male cone (strobilus masculinus) 5-2 and inner conical surface 2-3 close-fitting; Screw 6 is installed in the through hole 5-3 of guide way 5, tension is delivered to internal spline surface in the work from male cone (strobilus masculinus) 5-2, inner conical surface 2-3, thereby reach the purpose of clamping work pieces by screw 6.

Use by reality, axiality and also need not be faster than original to spline when loading and unloading in 0.03mm.Also prepare to add the method for guiding at other folders that rise, thereby improve the quality of products with split.
