Abstract
The utility model discloses a kind of oxygen content in steel sample fixture for processing, including sleeve, fixing axle, pinching screw, trip bolt, the sleeve is acted against through fixing axle on its boss, trip bolt is threaded through sleeve and is stuck in the card slot in fixing axle, so that fixing axle can not horizontal play but free to rotate, pinching screw is threaded through fixing axle and clamps the sample in its end card slot.Its advantage is：Simple in structure, easy for operation, for specimen holder in fixture, the directly hand-held sample of not employment improves ground effect and efficiency, sample mass is high after grinding, mitigates labor intensity of operating staff, can avoid the splash of ether coolant to human hand, and security greatly improves.
Description
Technical field
The utility model is related to a kind of processing accessories in metallurgical inspection assay technique field, contain more particularly to oxygen in a kind of steel
Measure sample fixture for processing.
Background technology
Oxygen content in steel sample is one end with the nail-like structure of tip, one end with boss, round bar it is a diameter of
Sample needs the oxide layer by round bar part to grind off before inspection is chemically examined, and is cooled down during grinding with ether.At present,
Still without dedicated clamping device, it is exactly usually that people is directly held with hand, polishes on sandbag machine, both dangerous, the effect ground
Fruit is also bad, of low quality, and work efficiency is low, and labor intensity of operating staff is big.In addition, ether cools down usually in grinding process
Splash on hand, stimulates skin to people.
Utility model content
To overcome prior art defect, the technical issues of the utility model solves, is to provide a kind of oxygen content in steel sample and adds
Work fixture, simple in structure, easy for operation, for specimen holder in fixture, the directly hand-held sample of not employment improves ground effect
And efficiency, sample mass is high after grinding, mitigates labor intensity of operating staff, can avoid the splash of ether coolant to human hand, and
Security greatly improves.
In order to achieve the above object, the utility model is realized using following technical scheme：
A kind of oxygen content in steel sample fixture for processing, including sleeve, fixing axle, pinching screw, trip bolt, feature
It is, the fixing axle is a rod structure with boss, without the centre-drilling hole at boss end, diameter of phi d and drilling depth h
With sample matched design, in Φ d holes Shen positions the side face drilling of fixing axle it is one bigger 0.5mm holes Φ D than sample boss overall diameter,
Depth to fixing axle center line, along fixing axle side open width t=Φ d notch connected with Φ D holes, depth and Φ d holes connect
It is logical, with the side of Φ D holes fixing axle in 90 ° be equipped with the matched clamping screw hole of pinching screw, be equipped in fixing axle outer surface with
The card slot of sleeve matched design, width b is bigger 0.5mm than trip bolt overall diameter, depth 0.8-1.5mm；The sleeve passes through
Fixing axle acts against fixing axle boss end, and trip bolt is threaded through the fastening screw hole that sleeve is equipped with, the card slot being stuck in fixing axle
Place by fixing axle together with sleeve connection, makes fixing axle can not horizontal play but free to rotate；The pinching screw is screwed in
On clamping screw hole in fixing axle.
Compared with prior art, the beneficial effects of the utility model are：
1) it is simple in structure, it is easy for operation；
2) for specimen holder in fixture, the directly hand-held sample of not employment improves ground effect and efficiency, it is ensured that tried after grinding
Sample quality, and mitigate labor intensity of operating staff；
3) sample is directly held without human hand, away from abrasive machine, the splash of ether coolant can be avoided to human hand, and pacified
Full property greatly improves.

Specific embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings：
Fig. 1-Fig. 3 is seen, the utility model is related to a kind of oxygen content in steel sample fixture for processing, including sleeve 1, fixing axle
2nd, pinching screw 3, trip bolt 4, the fixing axle 2 is a rod structure with boss 24, without the centre-drilling hole at boss end,
Its diameter of phi d and drilling depth h and 5 matched design of sample, in Φ d holes Shen positions, the side face drilling one of fixing axle 2 is than sample 5
Big 0.5mm holes Φ D of boss overall diameter, the center line of depth to fixing axle 2, then open along 2 side of fixing axle the slot of width t=Φ d
Mouth 21 is connected with Φ D holes, depth is connected with Φ d holes, is formed sample 5 and is installed card slot；It is set with the side of Φ D holes fixing axle 2 in 90 °
Have and pinching screw 3 is matched clamps screw hole 22, card slot 23 with 1 matched design of sleeve is equipped in 2 outer surface of fixing axle, it is wide
Degree b is bigger 0.5mm than 4 overall diameter of trip bolt, depth 0.8-1.5mm；The sleeve 1 acts against fixed crown of roll through fixing axle 2
24 end of platform, trip bolt 4 are threaded through the fastening screw hole that sleeve 1 is equipped with, and are stuck at the card slot 23 in fixing axle 2, by fixing axle 2 with
Sleeve 1 links together so that fixing axle 2 can not horizontal play but free to rotate, so sample 5 can under belt sander drive
It is freely rotated, achievees the purpose that grind away oxide layer on sample 5；The pinching screw 3 is screwed in the clamping screw hole 22 in fixing axle 2
On.
Operation principle：
Fixing axle 2 and sleeve 1 are installed according to the method described above, before the sample 5 of " nail " shape is put into fixing axle 2
In the sample card slot at end, pinching screw 3 is tightened, the sample 5 of " nail " shape is clamped, it is thus that sample 5 and the practicality is new
Type device is fixed together.
The round bar part of sample 5 is gently contacted belt sander by 1 end of human hand holding sleeve, and sample 5 can under belt sander drive
It is freely rotated, after abrasive band can grind away the oxide layer of 5 round bar part of sample, unclamps pinching screw 3, take out sample 5, you can
Complete sample processing oxide layer work.
Repeating above step can batch machining sample 5 one by one.
