Description
Technical field
The utility model is related to a kind of clamping devices for processing thin-walled cylinder shape inner bore of part, belong to mechanical manufacturing technology
Field.
Background technology
In the endoporus of processing thin-walled cylinder class part on horizontal lathe, generally using scroll chuck or " one support of folder " (three
Jaw self-centering chuck and centre frame) mode, realize the positioning to part and clamping.This installation way has the following problems,
On the one hand, during clamping parts, three claws of scroll chuck are directly contacted with piece surface, part outer surface are easily scratched, to zero
The roughness and precision of part outer round surface have an impact, on the other hand, part shape in thin-wall tube-shaped, the rigidity of its own compared with
Difference, in clamping process, part can produce part under the action of by clamping force and the selection of clamped position and contact area is improper
Raw larger flexible deformation, turnery processing metapore after unclamping scroll chuck, with the recovery of flexible deformation, make part into circle
Larger form error is generated, and then influences its machining accuracy.
The content of the invention
The purpose of this utility model is to overcome the defects of prior art, in order to solve Thin-wall cylindrical part because itself
Poor rigidity, influence of the deformation generated in process to its machining accuracy propose a kind of for processing thin-walled cylinder shape part
The clamping device of endoporus.
The utility model is mainly characterized by increase transition gripping sleeve, the transition between the claw and part of scroll chuck
Gripping sleeve is machined with fan-shaped gripping block and with axially open, to improve the contact area of clamping element and piece surface and clamping
The distribution of force at end reduces pinching deformation, so as to ensure the machining accuracy of part.
The purpose of this utility model is achieved through the following technical solutions.
A kind of clamping device for being used to process thin-walled parts endoporus, including：Chuck, transition gripping sleeve, centre frame, wherein blocking
Disk and centre frame provide attachment for oneself for lathe, and transition gripping sleeve is thin-wall tube-shaped structure, and internal diameter is consistent with part to be processed internal diameter, long
Degree is isometric with the claw of chuck；Outer circle processes 3 secter pats vertically, and along the circumferential direction uniformly distributed, each secter pat adds vertically
1 elongated slot wide with claw of work, for the connection of transition gripping sleeve 2 and claw；In the fan groove adjacent with each secter pat
Arc section is machined at 1/2 axial length, 3 secter pats are connected as a single entity, 1 arc section wherein is machined with opening, makes
Transition gripping sleeve 2 has certain elasticity；The endoporus of transition gripping sleeve 2 is stepped hole, for the axially position of part；
During clamping parts, first transition gripping sleeve 2 is connected by the elongated slot on its 3 secter pats with 3 claws simultaneously, then
One end of part is stretched into transition gripping sleeve 2, and with the step surface of transition gripping sleeve 2 close to, realize axially position, part
The other end is held up with centre frame, then clamps workpiece centering, carries out the processing of endoporus.
Advantageous effect
The prior art is compared, when the utility model realizes processing thin-walled cylinder shape inner bore of part on horizontal lathe, although still
Using the installation way of " one support of folder ", but part is clamped by designing and producing transition gripping sleeve, can effectively prevented thin
Wall cylindrical part is because of the poor rigidity of itself, influence of the deformation generated in process to its machining accuracy.The utility model
Simple and reasonable, when use, is convenient and efficient.

Embodiment 1
As shown in Figure 1, for the clamping device of processing thin-walled cylinder shape inner bore of part, including chuck 1, transition gripping sleeve 2, in
Heart frame 3.Chuck 1 and centre frame 3 provide attachment for oneself for lathe, and transition gripping sleeve 2 is thin-wall tube-shaped structure, as shown in Fig. 2, internal diameter with
Part to be processed outer diameter is consistent, and length is isometric with claw；Outer circle processes 3 secter pats vertically, is evenly distributed in circumferencial direction, each
Secter pat processes 1 elongated slot wide with claw vertically, for the connection of transition gripping sleeve 2 and claw；With each sector
Arc section (axial length is no more than 8mm) is machined at adjacent 1/2 axial length of fan groove of block, 3 secter pats are linked as one
Body, 1 arc section wherein are machined with opening, transition gripping sleeve 2 are made to have certain elasticity；The endoporus of transition gripping sleeve 2 is
Stepped hole, for the axially position of part.
During clamping parts, first transition gripping sleeve 2 is connected by the elongated slot on its 3 secter pats with 3 claws simultaneously, then
One end of part is stretched into transition gripping sleeve 2, and with the step surface of transition gripping sleeve 2 close to, realize axially position, part
The other end is held up with centre frame, then clamps part centering, carries out the processing of endoporus.Transition gripping sleeve 2 in the utility model,
Its internal diameter size is determined according to the outer diameter size of processing part, wall thickness is generally in 5~8mm.
