Description
Technical field
The utility model belongs to Piston Machining equipment technical field, is specifically related to a kind of outside piston finishing clamping dress
It sets.
Background technique
Piston is the key part of minute vehicle, requires to mitigate zero under the premise of meeting service performance and intensity requirement
The weight of part itself, therefore material is high sial.The material hardness is low, and drawing requirement piston external diameter roughness is 0.8, outside product
Circle dimensional accuracy and roughness can only lean on last finishing processing to complete.Piston depth inner hole is rectangle, and step hole wall is thin, no matter uses
Equipment three-jaw self-centering chuck or the soft tight inner wall of claw clip of self-control, if clamping precision is poor, clamping force is uneven or clamping force is excessive
Deng easily causing piston external diameter and the accuracy of form and position be overproof, influence product quality.For this case, outside piston essence is devised
Process clamping device.
Summary of the invention
In order to solve the above-mentioned technical problem, it is simple to provide a kind of structure for the utility model, easy to operate, and can effectively solve
Certainly piston clamping deformation problem guarantees the processing quality of part and the outside piston finishing clamping device of production efficiency.
The technical solution adopted in the utility model is: a kind of outside piston finishing clamping device, including fixing body, positioning
Bushing and strain pin；It is equipped with bushing mounting portion at fixing body front end, is set with positioning bushing on bushing mounting portion, pacifies close to bushing
Dress portion is equipped with screw thread；Fixing body front end surface is equipped with the tie rod holes along installation body axis direction setting, is equipped with edge at screw thread
The pin hole that is arranged radially of fixing body, pin hole be connected to tie rod holes；Nut is equipped on fixing body at screw thread, is equipped with pin in pin hole,
The size of pin hole is greater than the size of pin, and the both ends of pin are connect with nut respectively；Connecting rod, one end of pin and connecting rod are equipped in tie rod holes
The other end of connection, connecting rod is equipped with strain pin.
In above-mentioned outside piston finishing clamping device, set that there are two coaxial through-holes on the nut side wall；Pin
Both ends be separately positioned on nut in two through-holes, screw, the inner end of two screws are equipped on nut side wall in two through-holes
Respectively with two end in contact of pin.
In above-mentioned outside piston finishing clamping device, the fixing body rear portion is using Mohs cone.
Compared with prior art, the utility model has the beneficial effects that
Piston step hole is packed into the positioning surface of positioning bushing, makes piston end surface by the utility model for adding piston working hour
It is close to positioning bush end face, and the strain pin upper installing hole on connecting rod is inserted into strain pin and connect with connecting rod to positive piston pin hole,
Rotary nut drives screw, pin to move backward together, so that workpiece is tightened up pin shaft and compresses to effective；It not only can guarantee size public affairs
Difference, the success of roughness time processing, and also this device need only replace positioning bushing, and strain pin can be used for a series of pistons
Processing, adaptability is good, and solves the problems, such as piston clamping deformation, guarantees the processing quality and production efficiency of part, this reality
With novel advantage also simple, easy to operate with structure.
Detailed description of the invention
The cross-sectional view of Fig. 1 the utility model.
The structure chart of the fixing body of Fig. 2 the utility model.
The structure chart of the connecting rod of Fig. 3 the utility model.
The main view of the strain pin of Fig. 4 the utility model.

Specific embodiment
The utility model is described further with reference to the accompanying drawing.
As shown in Figure 1, the utility model includes fixing body 1, positioning bushing 5 and strain pin 7.As shown in Fig. 2, fixing body 1
The Mohs cone at rear portion, convenient for being mounted in lathe spindle hole by Morse's taper.Bushing mounting portion is equipped at 1 front end of fixing body
11, positioning bushing 5 is set on bushing mounting portion 11；Screw thread 12 is equipped with close to bushing mounting portion 11；In 1 front end surface of fixing body
Equipped with the tie rod holes 13 along installation body axis direction setting, it is equipped with the pin hole 14 being arranged radially along fixing body at screw thread 12,
Pin hole 14 is connected to tie rod holes 13.
Nut 2 is equipped on fixing body 2 at screw thread, pin 4 is equipped in pin hole 14, sets that there are two same on 2 side wall of nut
The through-hole of axis；The both ends of pin 4 are separately positioned on nut 2 in two through-holes, are equipped with screw 3 on 2 side wall of nut in two through-holes,
The inner end of two screws 3 respectively with two end in contact of pin 4.The size of pin hole 14 is greater than the size of pin 4, and therefore, pin 4 can be with spiral shell
Mother does certain rotation and moves back movement, tenses workpiece.Connecting rod 6 is equipped in tie rod holes 13, pin 4 is connect with one end of connecting rod 5, connecting rod
5 other end is equipped with strain pin 7.
When the utility model is used, fixing body 1 is mounted in lathe spindle hole by Morse's taper, nut 2 and fixing body 1
After spinning, connecting rod 6 is fixed in fixing body 1 with screw 3, pin 4, positioning bushing 5 and fixing body are closed using gapless is sliding.Processing
When need only by piston step inner hole sleeve mounted in positioning bushing 5 on, piston and positioning bushing 5 using H7/g6 cooperate, strain pin 7 will
Piston is connect with connecting rod 6, rotary nut 2, and screw 3, pin 4 is driven to move backward together, and workpiece is made to be tightened up the axial effectively pressure of pin 7
Tightly；It not only can guarantee that dimensional tolerance, the success of roughness time processing, and this device need only be replaced and position bushing 5, strain pin 7,
It can be used for a series of processing of pistons, adaptability to be good, and solves the problems, such as piston clamping deformation, guarantees the processing of part
Quality and production efficiency, the utility model also have structure simple, easy to operate advantage.
