The clamping portion consists of a drawbar (10), a threaded shaft (4) and a threaded sleeve (3), the drawbar is connected with the threaded shaft, the threaded shaft matches with the threaded sleeve, a handle (5) is mounted on the threaded sleeve, and a drawbar head (10-1) is provided with a pin hole (10-2) corresponding to a piston pin hole. The special fixture can be used for fixing pistons of different specifications, is high in applicability and simple in operation, realizes one-step clamping in place, and has the advantages of high production efficiency and accurate clamping positions.

Description

The piston port Special Fixture for Machining
Technical field
The utility model relates to field of machining, particularly belongs to a kind of special fixture that is used for piston port processing.
Background technology
Piston is the critical component of automobile engine, and piston machining accuracy is the prerequisite of engine assembling.Piston needs the multistep operation from the blank depanning to the machined completion, and per step operation all has strict processing technology.Piston port processing need be carried out on the vertical milling lathe of special use; For guaranteeing the precision and the roughness of piston port processing; The producer that produces piston pays much attention to the jig Design of piston on the vertical milling lathe, is processed in technologic feasibility to guarantee piston port, and has the high efficiency of processing.But, the anchor clamps ubiquity clamping complex procedures, the not high drawback of machining accuracy that adopt at present.
Summary of the invention
The purpose of the utility model promptly is to provide a kind of novel piston port Special Fixture for Machining, meets the processing technology requirement to reach, and guarantees the piston port machining accuracy, the purpose of enhancing productivity.
The piston port Special Fixture for Machining that the utility model provided; Comprise support component and clamping parts, it is characterized in that described support component is meant base, joins dish, seam dish, bottom; Base is fixed on the working face of vertical knee-type milling machine, and bottom is fixedly mounted on the bottom of base; The top of joining dish is circular discs, between seam dish and base, realizes that installation between the two connects; The bottom of joining dish is circular jacket casing; Described clamping parts are made up of pull bar, thread spindle, thread bush; Pull bar is connected with thread spindle, and the thread spindle hypomere has screw thread, cooperates with thread bush, and thread bush is installed in the lower edge face below of circular jacket casing; Establish spring between thread spindle and the bottom; Handle installation on the body of thread bush; Rod head has pin-and-hole, and is corresponding with piston pin hole.
The piston port Special Fixture for Machining that the utility model provided during work, is placed on piston on the seam dish; Make piston pin hole corresponding with the rod head pin-and-hole; Pass steady pin then, rotate thread bush to operator's direction pulling handle, pull bar, thread spindle move down under the effect of screw thread driving force; Thereby be strained and fixed piston, can process.After machining, the counter-rotation handle, pull bar, thread spindle homing under spring action is taken down steady pin, takes off piston, can carry out the processing of next piston then.
The utility model can be selected the seam dish according to the piston model, the fixing piston of different model, and adaptability is strong, and simple to operate, and clamping settles at one go, has production efficiency height, clamping position characteristic of accurate.
Description of drawings
Accompanying drawing is the structural representation of the utility model, wherein,
1, joins dish; 1-1, circular discs; 1-2, circular jacket casing; 2, base; 3, thread bush; 4, thread spindle; 5, handle; 6, bottom; 7, backstay; 8, spring; 9, seam dish; 10, pull bar; 10-1, rod head; 10-2, pin-and-hole.
The specific embodiment
Shown in accompanying drawing, piston port Special Fixture for Machining disclosed in the utility model mainly comprises support component and clamping parts.Wherein, support component is meant base 2, joins dish 1, seam dish 9 and bottom 6.Base is cylindrical, and its bottom surface is fixed on the working face of vertical knee-type milling machine, and end face realizes installing connection through joining the circular discs 1-1 and the seam dish that coil top.Place the piston of preprocessing on the seam dish.
The utility model the clamping parts be meant pull bar 10, thread spindle 4, thread bush 3.Rod head 10-1 has pin-and-hole 10-2, and is corresponding with piston pin hole, can piston and rod head be bound up through a steady pin.Pull bar becomes one through being threaded with thread spindle.The thread spindle hypomere has screw thread, cooperates with thread bush, establishes spring 8 between thread spindle and the bottom 6.Above-mentioned to join dish 1 bottom be circular jacket casing 1-2, and during assembling, thread bush promptly is installed on the lower edge face below of circular jacket casing, thereby when thread spindle is moved downward, can produce relative motion between clamping parts and the above-mentioned support component.Handle installation 5 on the body of thread bush, during clamping, to operator's direction pulling handle; After machining, the counter-rotation handle.
Because handle 5 and pass between the steady pin of rod head pin-and-hole in relative rotation that angle has determined the size of clamping power and the variation of piston position; So; In order to make the clamping accurate positioning, the bottom surface of the utility model base is provided with backstay 7, during clamping; Above-mentioned steady pin one end is against on the backstay, and the other end passes pin-and-hole and gets final product.According to the different model of piston, can change the position location of backstay 7, make the clamping parts obtain suitable moment of torsion with fixed piston.
