Description
Technical Field
The utility model relates to a mould is used in processing, especially a special mould subassembly of thin wall sleeve class work piece.
Background
In industrial production activities, some thin-walled sleeve workpieces need to be machined, and clamps such as three-jaw chucks are generally used for clamping and fixing during machining. Because the wall thickness of the workpiece is thin, the workpiece such as a thin-wall sleeve often deforms in the clamping process, and particularly when the machining precision requirement is high, the geometric tolerance requirement and the design requirement cannot be met. There is therefore a need for a method or apparatus that addresses the above-mentioned problems.
SUMMERY OF THE UTILITY MODEL
The utility model relates to a solve the above-mentioned not enough that prior art exists, provide a simple structure, design benefit, rationally distributed can guarantee that the special mould subassembly that can not take place to warp at clamping in-process thin wall sleeve class work piece.
The technical solution of the utility model is that: the utility model provides a special mould subassembly of thin wall sleeve class work piece which characterized in that: the mould assembly consists of a first mould, a second mould and a third mould 10,
the first mould comprises a sleeve body 1, one end of the sleeve body 1 is provided with an annular step 2, the other end of the sleeve body 1 is in threaded connection with a first nut 3, the middle part of the first nut 3 is provided with a through hole 4,
the second mould comprises a cylinder 5, one end of the cylinder 5 is provided with an end cover 6, the diameter of the end cover 6 is larger than the outer diameter of the cylinder 5, the other end of the cylinder 5 is provided with a stud 7, the stud 7 is sleeved with a gland 8, the outer side of the gland 8 is also provided with a second nut 9 in threaded connection with the stud 7,
the third mold 10 is a hollow cylinder, and the side wall thereof is provided with clamping gaps distributed along the bus direction.
Compared with the prior art, the utility model, have following advantage:
the mould component with the structure is simple in structure, ingenious in design and reasonable in layout, and a set of special structure is designed aiming at the problem that when a traditional tool clamp clamps a thin-wall sleeve workpiece, the workpiece is easy to deform to influence the machining precision. It comprises three kinds of moulds, the work piece can be followed to the outside to first kind of mould, the work piece can be followed to the inboard support piece to the second kind of mould, and these two kinds of moulds all realize spacing and pressing from both sides tightly the work piece in the axial, in the course of working of hole and outer wall like this, the work piece can not take place to warp under the support of mould, and the contact area between anchor clamps and the work piece when third kind of mould has then greatly increased the tip and has pressed from both sides tightly, thereby reduce pressure, avoid the atress to concentrate, and then realize preventing the purpose that the work piece warp under the prerequisite of reliable clamp tightly. And the manufacturing process of the mould component is simple, the manufacturing cost is low, so that the mould component has multiple advantages, is particularly suitable for popularization and application in the field, and has a very wide market prospect.

Detailed Description
The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1, 2, and 3: a special mould component for thin-wall sleeve workpieces comprises a first mould, a second mould and a third mould 10,
the first mould comprises a sleeve body 1, one end of the sleeve body 1 is provided with an annular step 2, the other end of the sleeve body 1 is in threaded connection with a first nut 3, the middle part of the first nut 3 is provided with a through hole 4,
the second mould comprises a cylinder 5, one end of the cylinder 5 is provided with an end cover 6, the diameter of the end cover 6 is larger than the outer diameter of the cylinder 5, the other end of the cylinder 5 is provided with a stud 7, the stud 7 is sleeved with a gland 8, the outer side of the gland 8 is also provided with a second nut 9 in threaded connection with the stud 7,
the third mold 10 is a hollow cylinder, and the side wall thereof is provided with clamping gaps distributed along the bus direction.
The utility model discloses the working process of special mould subassembly of thin wall sleeve class work piece as follows: when a workpiece 11 such as a thin-wall sleeve needs to be machined, the workpiece is firstly placed into an inner cavity of a sleeve body 1, then a first nut 3 is screwed at one end of the sleeve body 1, at the moment, one end of the workpiece 11 is in contact with an annular step 2, the other end of the workpiece is in contact with the first nut 3 (as shown in fig. 1), and the workpiece 11 is clamped by a first fixture, so that the inner wall of the workpiece can be roughly machined.
After the rough machining of the inner wall of the workpiece 11 is finished, the first nut 3 is unscrewed, the workpiece 11 is taken out, the workpiece 11 is sleeved on the cylinder 5, the gland 8 is sleeved on the stud 7 (the stud 7 penetrates through a through hole formed in the center of the gland 8), the second nut 9 is screwed on the outer side of the gland 8, one end of the workpiece 11 is in contact with the edge of the end cover 6 at the moment, the other end of the workpiece 11 is in contact with the edge of the gland 8 (as shown in fig. 2), and the workpiece 11 is clamped by the second mould, so that the outer wall of the workpiece can be machined;
after the outer wall of the workpiece 11 is machined, the second nut 9 is unscrewed, the workpiece 11 is taken down from the cylinder 5, the third mould 10 is sleeved at one end of the workpiece 11, then the third mould 10 is clamped by the three-jaw chuck, and under the action of the three-jaw chuck, the third mould 10 is folded and contacts with the outer wall of the workpiece 11, so that the workpiece 11 is clamped (as shown in fig. 3), and at the moment, the inner wall of the workpiece 11 can be subjected to finish machining; since the third mold 10 is in contact with the workpiece 11 in the entire circumferential direction, the local pressure is low, and the workpiece 11 can be prevented from deforming under the premise of effective clamping.
