Abstract

The utility model discloses a ball-pin flexible chuck installed on a chuck base of a machine tool. The ball-pin flexible chuck comprises a fixing portion, a neck portion and a head portion which are integrated. The head portion is provided with a clamping hole for allowing a ball-pin handle to be inserted into in the axial direction, and the head portion is further provided with an opening groove communicated with the clamping hole which is sequentially composed of a ball-pin clamping face, an axial positioning face and an auxiliary clamping internal conical face from inside to outside along the axis. The outside of the head portion is provided with a pressing face matched with the internal conical face of the chuck base. The ball-pin flexible chuck is good in clamping effect, strong in clamping rigidity and capable of preventing deformation of a ball-pin in machining.

Description

The ball pin collet
Technical field
The utility model relates to a kind of ball pin collet, belongs to the lathe special fixture.
Background technology
Strength member during ball pin on automobile, tractor all has higher requirements to its Physical and mechanical properties, and the existing cold forming method that generally adopts is made blank, re-uses lathe and carries out fine finishining.At present, when processing ball pin on lathe, the clamping of workpiece generally adopts pawl folder or axial direction positioning device to carry out clamping to it, and its shortcoming is: at first, use pawl folder clamping ball pin, clamping is unstable and easily cause workpiece to damage; Secondly, and axial direction positioning device is the tubular structure with axis hole, uses the handle of axial direction positioning device clamping ball pin, because the difference of ball pin dimensions, and chuck is rigidity, need to change the chuck of different size according to the ball pin of different size, and troublesome poeration and cost are higher; Again, traditional ball pin overhang when clamping is longer, causes ball pin that deformation occurs when machining.
The utility model content
The utility model is intended to provide a kind of ball pin collet, its good clamping effect, has elasticity and can prevent that ball pin from adding deformation occurs man-hour.
The purpose of this utility model can reach by following measures: a kind of ball pin collet, this collet is installed on the base of the carrier head of lathe, it comprises integrated fixed part, neck and head, described head shaft upwards has the clamping hole that inserts for the ball pin handle, this head also has the open slot that communicates with clamping hole, and described clamping hole is comprised of ball pin clamping area, axial locating surface and auxiliary clamp inner conical surface from inside to outside successively along axis; Described head outer with base of the carrier head inner conical surface coupling seal face.
The technique scheme difference with the prior art is: at first, the chuck fixed part is connected with the lathe pull bar, the seal face of chuck head coordinates with the inner conical surface of base of the carrier head, when lathe pull bar post-tensioning, open slot is closed gradually, and the chuck seal face is elastic shrinkage gradually inwardly, the compression clamping hole, thereby the clamping balls pin handle is suitable for the ball pin clamping operation in the certain specification scope; Secondly, the auxiliary clamp inner conical surface relies on the micro-elastic deformation ball pin conical surface of tightly fitting, thereby increases ball pin integral retaining rigidity, reduces the circular runout in ball pin processing; Again, because the length of clamping hole is enough, the length that overhangs when having reduced the ball pin clamping is conducive to reduce ball pin and adds the deformation that man-hour, cutting force caused, thus can be more stable size and dimension precision and the machined surface quality of assurance ball pin processing.
Further, described open slot is three-clove style, makes ball pin uniform stressed when clamping.
The utility model is simple in structure, and good clamping effect is suitable for promoting.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model ball pin collet embodiment;
Fig. 2 is the broken section structural representation of Fig. 1;
Fig. 3 is the right TV structure schematic diagram of Fig. 1.
Fig. 4 is the assembling schematic diagram of the utility model ball pin collet embodiment.
The specific embodiment
A kind of ball pin collet, as shown in Figure 1 and Figure 2, this chuck is divided into fixed part 1, neck 2 and head 3 from left to right, and fixed part 1, neck 2 and head 3 are one-body molded, fixed part 1 and neck 2 are tubular structure, and the diameter of neck 2 is slightly less than the diameter of fixed part 1.Head 3 profiles are centrum, and what wherein be connected with neck 2 is seal face.Have the clamping hole 4 of clamping ball pin handle in the middle of this head 3, this clamping hole 4 is comprised of ball pin clamping area 41, axial locating surface 42 and auxiliary clamp inner conical surface 43 from inside to outside successively along axis.Also have three open slots 5 that communicate with clamping hole 4 on this head 3, open slot 53 right-hand members from the head extends to neck 2, and as shown in Figure 3, the angle between adjacent apertures groove 5 is 120 °, forms three-clove style open slot structure.
See the installation diagram of Fig. 4, during use, the in-built handle that enters ball pin 8 of the clamping hole 4 of head 3, the seal face of head 3 coordinates with base of the carrier head 6 inner conical surfaces, and fixed part 1 is connected with lathe pull bar 7, when lathe pull bar 7 post-tensioning, seal face is elastic shrinkage gradually inwardly, at first the ball pin clamping area 41 of clamping hole 4 clamps the handle of ball pin 8, and last auxiliary clamp inner conical surface 43 relies on tightly the fit conical surface of ball pin 8 of micro-elastic deformation, further clamps ball pin 8.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
