Abstract
The invention discloses a chuck used for machining synchronizer friction ring thin-walled parts. The chuck comprises a pull rod which is connected with a machine tool spindle and a body which is connected with the machine tool spindle through a connecting plate. The pull rod is sleeved with a push sleeve. The rear end of the machine tool spindle is connected with a spring, a mandril and a rotating shaft. The mandril is sleeved with a three-jaw device, and the rear end of the three-jaw device is provided with a positioning block. The pull rod pushes the push sleeve to move so as to make the three-jaw device achieve part positioning through the spring, and meanwhile drives the rotating shaft to move in the axial direction so that the end faces of the parts can be compressed or released, and the parts can be machined, assembled and disassembled by rotating the rotating shaft. According to the chuck used for machining the synchronizer friction ring thin-walled parts, the three-jaw chuck is adopted for positioning and clamping; in order to prevent deformation, the three-jaw device can move to achieve clamping through elastic force of the spring, clamping force is small, only the positioning effect can be achieved, and clamping depends on the end face compressing method; and in order to guarantee assembling and disassembling flexibility of the parts, the part assembling and disassembling requirement can be met by rotating by a certain angle while a pressing plate is released.

Make three-jaw realize part positioning by spring, axle axial movement is rotated simultaneously, so that part end face is compressed or unclamp, and pass through
Rotation rotary shaft realizes processing and the handling of part.
The present invention is further improved by:
Described machine tool chief axis pass through pull bar, gripper shoe support rotary shaft, rotation the tip of the axis setting pressing plate, and gripper shoe and
It is sphere-contact between pushing sleeve.
Described rotary shaft is provided with helicla flute and the pin making part unclamp and facilitating part handling.
It is mounted on the spindle that described spring passes through spring base.
Described three-jaw is installed on chuck by three pawl seats, and the contact surface of heart axle and three pawl seats is the conical surface；Three pawl seats are installed
In the groove of chuck, and can move up and down, and drive three-jaw and locating piece to move up and down.
The rear end setting gland of described heart axle and three pawl seats, gland installs spring by bolt and blocks up, the end of spring is fixed
Block in spring.
Axial locating piece is installed in the rear end of described chuck, and pressing plate is arranged on chuck by pressing plate seat.
Compared with prior art, the method have the advantages that
The inner conical surface of friction ring for synchronizer class part has 0.15 requirement of beating to tooth, and external tooth is finish forge direct forming,
Generally step up to process inner cone using profile of tooth and end face positioning, and this part belongs to thin-wall part, tooth shape locating clamps meeting
Deform it is impossible to ensure required precision, think that profile of tooth is only used for positioning, using the clamping side of end face compression by analysis
Formula, reaches the problem eliminating deformation.In order to improve positioning precision, the present invention adopts scroll chuck positioning clamping, in order to prevent becoming
Shape, makes the mobile clamping of three-jaw, clamping force very little using the elastic force of spring, only plays the role of positioning, the method that clamping compresses by end face,
In order to ensure part handling flexibly, employing rotates to an angle while clamp loose to meet the handling of part.
