Description
Technical field
The utility model is related to piston field more particularly to a kind of anti-slip piston fixing tools.
Background technology
Piston of automobile cans be compared to the central position of automobile engine, and extremely important status is accounted in engine start.
In recent years, due to the continuous improvement of engine reinforcing degree, rotating speed, mean effective pressure and the mean piston speed of engine are all
It has increased significantly than before, therefore the thermic load of engine and mechanical load both increase.And piston is due to starting
Important function in machine, in design, there has also been prodigious change and raisings with manufacture view, could meet society height in this way
It is required that discharge standard.
In order to promote piston face finish, need to carry out grinding and buffing to its outer surface after finishing.Due to
When being unable to stress when the exterior finish of piston and after polishing and be difficult to fix, and being fixed from inside, piston is easy in bruting process
In loosen, need to improve.
Utility model content
The purpose of this utility model is to provide a kind of anti-slip piston fixing tools, are fixed from internal piston,
And avoid slippage problem.
For this purpose, the utility model uses following technical scheme：
A kind of anti-slip piston fixing tool, including：Pedestal, riser, central shaft, lifting drive and drive block,
Two pieces of risers are symmetricly set on pedestal, and the central shaft is arranged between two pieces of riser top, and piston is set in two pieces of risers
Top, on the central shaft setting be respectively arranged on the bearing and be directed toward piston both sides inner wall obliquely there are two bearing
Swing arm, the swing arm bottom end is provided with non-slipping block, and the lifting drive is set on the base, the lifting driving
The extension rod for being directed toward central shaft is provided at the top of device, the drive block is arranged at the top of extension rod and under two swing arms
Side, the drive block top is provided with the arc surface tangent with swing arm.
Wherein, the non-slipping block is rubber block.
Wherein, the lifting drive is pneumatic cylinder.
Wherein, it is provided with axle sleeve at the top of the telescopic rod of the lifting drive, the bottom of the extension rod is fixed on axis
In set, the bolt of fixed extension rod is provided on the outside of the axle sleeve.
Wherein, it is provided with connecting plate between two pieces of risers top.
The beneficial effects of the utility model：A kind of anti-slip piston fixing tool, lifting drive elongation, which drives, drives
Motion block rises, and pushes the swing arm of both sides to be flipped up using arc surface so that non-slipping block contacts with piston inner wall and carries out piston
Limit, and avoid loosening problem, it is easy to operate, be conducive to the efficiency for promoting polishing tool.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The technical solution of the utility model is further illustrated with reference to Fig. 1 and by specific embodiment.
A kind of anti-slip piston fixing tool, including：Pedestal 1, riser 4, central shaft 8, lifting drive 2 and driving
Block 12, two pieces of risers 4 are symmetricly set on pedestal 1, and the central shaft 8 is arranged between two pieces of 4 top of riser, and piston 5 is arranged
Setting is respectively arranged on two bearings 9 and is referred to obliquely there are two bearing 9 on the top of two pieces of risers 4, the central shaft 8
Swing arm 6 to 5 both sides inner wall of piston, 6 bottom end of the swing arm is provided with non-slipping block 10, when swing arm 6 is flipped up, non-slipping block
10 contact with 5 both sides inner wall of piston and carry out outer support and fix, and avoid the shaking of piston 5.
The lifting drive 2 is arranged on pedestal 1, and 2 top of the lifting drive, which is provided with, is directed toward central shaft 8
Extension rod 11, the setting of the drive block 12 is at the top of extension rod 11 and below two swing arms 6,12 top of the drive block
It is provided with the arc surface tangent with swing arm 6.Swing arm 6 is pushed to be flipped up using arc surface when drive block 12 rises.
In the present embodiment, the non-slipping block 10 is rubber block, and wearability is good, and anti-skidding, effectively reinforces the fixation of piston,
Avoid slippage when polishing.
In the present embodiment, the lifting drive 2 is pneumatic cylinder, and control is flexible, the lifting of fast driving extension rod 11,
Facilitate the installation and removal of piston 5.
In the present embodiment, axle sleeve 3, the bottom of the extension rod 11 are provided at the top of the telescopic rod of the lifting drive 2
Portion is fixed in axle sleeve 3, and 3 outside of the axle sleeve is provided with the bolt of fixed extension rod 11, facilitates the installation of extension rod 11.
In the present embodiment, two pieces of risers are provided with connecting plate 7 between 4 top, and the structure for improving two pieces of risers 4 is steady
It is qualitative, strengthen support and limit to 5 inner cavity top of piston.
The above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With novel thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as
Limitations of the present invention.
