Abstract
The utility model relates to machining equipment, in particular to a clamping gripper, i.e. a semi-ball head workpiece clamping gripper for clamping workpiece during machining, which comprises two clamping fittings (1) with both ends connected with a machine tool, wherein, both clamping fittings are provided with opposite semi-cone shaped clamping cavities (2), thereby the clamping cavity formed by combining both clamping fittings is in the shape of a cone; the radial center of each clamping fitting is provided with a threaded through hole communicated with the clamping cavity; the inside of each threaded through hole is provided with a bolt (3) used as an eccentric block; the end parts of a clamper contact each other near the top of the cone of the clamping cavity after a handle is pressed down. The utility model can effectively clamp semi-spherical workpiece and brings convenience to the processing of semi-spherical workpiece.
Description
Technical field
The utility model relates to machining equipment, relates in particular to be used for the anchor clamps of holding workpiece in the middle of a kind of the processing.
Background technology
In the middle of machining, usually need to utilize some anchor clamps with piece-holder.For the workpiece of those profiles such as cylindrical, square, corresponding effectively clamping of anchor clamps.Yet for those profiles is spherical workpiece, and these anchor clamps all can't clamping.As, for the torque-shear type high-strength bolt, its particularity just is on the profile of head that its head is hemispherical and sphere pushes formation in the upsetting process, the nominal dimension of profile depends on blank upsetting amount and mold shape size.Therefore, the such pattern of original hex bolts can not be adopted in the location of its turning clamp, is substituted and must a kind of custom design put.
Summary of the invention
The utility model is intended to solve the defective that existing anchor clamps can't clamping hemispherical workpiece, and a kind of hemispherical work piece holder is provided.The utility model can effectively clamp the hemispherical workpiece, for the processing that has the hemispherical shape workpiece is provided convenience.
The utility model is achieved in that a kind of hemispherical head work piece holder, and it comprises two holders that the cylindrical hole of being with keyway is connected with lathe, and two holders are provided with relative half-conical bodily form clamping chamber separately, and the clamping chamber after two holders merge is a cone; Radial center at each holder is provided with the tapped through hole that is communicated with the clamping chamber, and when described two bolts were screwed into, their end contacted with each other near the top of clamping chamber cone.
Described hemispherical head work piece holder, the one side that described holder is offered the clamping chamber is provided with circular step, and its clamping chamber begins part and is flat segments.
Described hemispherical head work piece holder, described two holder one ends are pivotally connected with a split pin; The other end is provided with longitudinal hole and spring eye, and longitudinal hole is provided with connecting rod, and the connecting rod lower end is fastening with nut, and the pivotally connected of band split pin reinstated for the fork ear and with eccentric block one in the upper end, is provided with spring in the spring eye.
Described hemispherical head work piece holder is equipped with on the described eccentric block sagittal plane and is used for opening and the handle of the anchor clamps that lock.
The utility model adopts a kind of Hough clamping collet that is similar to cone tank, the both sides of cone tank are designed to different angles respectively give two-way location, and be aided with end face and cross the location, with shape and the technical specification that meets product, satisfy the processing request of product, utilize the eccentric throw of manually adjusting eccentric block to realize the location of tightening and six direction, thereby solved the clamping problem of hemispherical head workpiece, for the processing of hemispherical head workpiece is provided convenience.

The specific embodiment
As shown in Figure 1 to Figure 3: a kind of hemispherical head work piece holder, it comprises that the clamping chamber 2 that 1, two holder 1 of two holders that the cylindrical hole of being with keyway is connected with lathe is provided with after relative 2, two holders in half-conical bodily form clamping chamber 1 merge separately is a cone; Radial center at each holder 1 is provided with the tapped through hole that is communicated with clamping chamber 2, and when described two bolts 3 were screwed into, their end contacted with each other near the top of clamping chamber 2 cones.
The one side that described holder 1 is offered clamping chamber 2 is provided with circular step, and its clamping chamber begins part and is flat segments (seeing Fig. 3 for details).
Described two holder 1 one ends are pivotally connected with a split pin 4; The other end is provided with longitudinal hole and spring eye, and longitudinal hole is provided with connecting rod 5, and connecting rod 5 lower ends are fastening with nut 6, and the upper end is reinstated for fork ear 7 and with eccentric block one and is with the pivot 41 of split pin to be connected, and is provided with spring 8 in the spring eye.
Described fork ear 7 is provided with a horizontal pivotally connected eccentric block, is equipped with on this eccentric block sagittal plane to be used for opening and long handle handle 9 (see figure 2)s of the anchor clamps that lock.
The person of an ordinary skill in the technical field should recognize, the foregoing description only is used for explaining claim, rather than to the qualification of claim; The change of any essentiality content in claim all will drop within the protection domain of claim.
