Abstract
The utility model belongs to aircraft manufacturing field of machining, is related to a kind of clamping device of car thin-walled pad endoporus.The car thin-walled pad endoporus clamping device is made up of 2 two parts of locking nut 1 and clamping sleeve.Wherein, through hole is provided among the clamping sleeve and locking nut, and clamping sleeve end set has the stepped hole for accommodating thin-walled pad, the docking of both clamping sleeve and locking nut, grips the thin-walled pad being arranged in stepped hole.The utility model can not only solve the Set and Positioning of batch varying number thin-walled pad, also it is effectively guaranteed the axiality of part during part car system, greatly reduce part difficulty of processing, clamping and machining accuracy are improved, and part rejection can be reduced, shorten the process-cycle, reduce cost and easy to spread.
Description
Technical field
The utility model belongs to aircraft manufacturing field of machining, is related to a kind of clamping dress of car thin-walled pad endoporus
Put.
Background technology
Pad is when entering hole machined in driving system, typically can be same with criticizing by multiple pads in order to ensure the axiality of pad
Shi Jiagong., can only be by locking the single clamping of vice to car endoporus, single but universal lathe can not be by pad batch clamping
During placing pad, easy run-off the straight, the coaxiality of inner hole of institute's car is not high, and surface is irregular, is easily deformed, and causes to give up
Product rate is higher, has a strong impact on manufacturing schedule.
Utility model content
Purpose of utility model：The clamping dress of a kind of axiality for being capable of effective guarantee batch machining pad and precision is provided
Put.
Technical scheme：
A kind of car thin-walled pad endoporus clamping device, it is made up of two parts of locking nut and clamping sleeve, wherein,
Through hole is provided among the clamping sleeve and locking nut, and clamping sleeve end set has for accommodating thin-walled pad
Both stepped hole, clamping sleeve and locking nut dock, and grip the thin-walled pad being arranged in stepped hole.
The nut is hex nut, and its center through-hole diameter is less than clamping sleeve step bore dia.
Before the compacting of batch thin-walled pad, it is no less than 1mm beyond end surface of step hole.
Described locking nut docking clamping sleeve one end is internally provided with the pressure rings around through hole.
Socket pressure regulation part, the pressure regulation part are divided into two parts in the locking nut through hole, and smaller-diameter portion is socketed in lock
In tight nut through hole, larger diameter portion is located in clamping sleeve stepped hole, and the two central hole size being mutually communicated is not small
In car hole.
Beneficial effect：
The advantages of the utility model：By the research to lathe structure and thin-walled pad, a kind of car thin-walled pad is proposed
The clamping device of endoporus, can not only solve the Set and Positioning of part volume, moreover it is possible to be effectively guaranteed during part car system
The axiality of part, part difficulty of processing is greatly reduced, improve clamping and machining accuracy, while convenient mounting and clamping, can meet
The clamping requirement of varying number part, it is possible to increase combination property, shorten the process-cycle, reduce cost.

Embodiment
The utility model structure is described in further detail below
Referring to Fig. 1, it is the utility model car thin-walled pad endoporus clamping device first embodiment structural representation
Figure.The car thin-walled pad endoporus clamping device is made up of 2 two parts of locking nut 1 and clamping sleeve.Wherein, the dress
Through hole is provided among chuck cylinder and locking nut, for car hole, wherein, locking nut is hex nut, to facilitate lathe
Clamping.The clamping sleeve end set has the stepped hole for accommodating thin-walled pad.Before the compacting of batch thin-walled pad, it exceeds
End surface of step hole is no less than 1mm, and the docking of both clamping sleeve and locking nut, be fixed and clamped the thin-walled pad being arranged in stepped hole
Piece, then lathe tool is realized through through hole carries out endoporus car system to the thin-walled parts in stepped hole.
Referring to Fig. 2, it is the utility model car thin-walled pad endoporus clamping device second embodiment structural representation
Figure.The embodiment structure is similar with first embodiment, is simply provided with the inner face of locking nut docking clamping sleeve
Pressure rings, the pressure rings are around through hole, for extruding the thin-walled parts in stepped hole, to increase the clamping of batch thin-walled parts effect
Fruit.
Referring to Fig. 3, it is the embodiment structural representation of the utility model car thin-walled pad endoporus clamping device the 3rd.
In the embodiment, in addition to one carry centre bore pressure regulation part.The pressure regulation part divides both ends, wherein, the smaller one end of diameter, outside
Face is connected provided with external screw thread with locking nut through hole, is relatively large in diameter one end and is arranged in the stepped hole of clamping sleeve, for pressing
Thin-walled parts.In addition, according to the difference for being actually needed clamping thin-walled number of parts, the pressure regulation part of different-thickness can be chosen, or
Person realizes the pressing clamping to varying number thin-walled parts by precession pressure regulation part.
The utility model clamping device can be adapted to the clamping of varying number thin-walled parts, can complete batch thin-walled parts
Che Kong, and ensure axiality and precision, and clamping, easy to process, efficiency high, there is larger actual application value.
