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.

[technical field]
The invention belongs to machining technology field, it is related to a kind of friction ring for synchronizer thin-wall part processing chuck.
[background technology]
Friction ring for synchronizer class parts batch is very big, belongs to thin-wall part, and clamping is yielding, and beat is fast, so to processing When locating clip critical ask higher, handling flexibly will belong to mechanical linkage structure, the external comparative maturity of clip-like, former employing Import, often covers about 100,000 yuan about, and the manufacturing cycle is longer, brings a lot of puzzlements to produced on-site.
Being continuously increased with yield, and the damage of the part of former inlet fixture, need substantial amounts of fixture and accessory, Costly, the cycle is long, after live Machining Analysis, is badly in need of a kind of low cost, manufacturing cycle short chuck.
[content of the invention]
It is an object of the invention to overcoming the shortcoming of above-mentioned prior art, provide a kind of friction ring for synchronizer thin-wall part processing Use chuck.
For reaching above-mentioned purpose, the present invention employs the following technical solutions and is achieved:
A kind of friction ring for synchronizer thin-wall part processing chuck, including the pull bar being connected with machine tool chief axis and by being connected The body that disk is connected with machine tool chief axis, pull bar is set with pushing sleeve;Chuck is provided with body, connecting spring seat, bullet on chuck Spring, heart axle and rotary shaft, chuck is set with three pawl seats, three-jaw, and locating piece is installed in the rear end of three-jaw;Pull bar promotes pushing sleeve to move, 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.
