Description
Technical field
The invention belongs to technical field of mechanical processing, specifically a kind of clamping and positioning device.
Background technique
At present at the hole in the valve block of processing hydraulic oil cylinder, since valve block is the symmetrical square block of on-circular, so one
As do not have to lathe process, even if can be with, it is also desirable to use chuck, but use chuck centering and clamp all very tired
Difficulty, so be not generally placed on lathe the hole for processing, but drilling out required on drilling machine, but the hole processed on drilling machine its
Verticality, roughness and precision relative to datum level is all relatively poor, and reprocessing for valve block is all higher with scrappage.And it bores
It is longer the time required to hole, reduce working efficiency.
Summary of the invention
It is an object of the invention to overcome the influence of manual operation, one kind is provided and can be accurately positioned and steps up, is easy to operate, tying
The clamping and positioning device that structure is simple, appearance is small and exquisite, is conveniently replaceable in case of damage.
The technical scheme is that including chassis, the installation for placing valve block to be processed is equipped in the middle part of the chassis
Hole, the pilot hole being connected with mounting hole, chassis side are equipped with threaded hole, and threaded hole is connected with pilot hole；It further include limit
Block；The limited block includes the shank cooperated with pilot hole, two limit plate portions connecting with shank, is formed between two limit plate portions
For limiting the limiting slot of valve block to be processed；It further include for pushing limited block to move along pilot hole to clamp valve block to be processed
Mandril, at threaded hole, the shank end face of mandrel ends and limited block offsets mandril spinning.
Two limit plate portion is that the long limit plate portion cooperated with valve block long face to be processed and valve block short face to be processed cooperate
Short limit plate portion.
The mounting hole is square hole, and the area of mounting hole is greater than the area of valve block to be processed.
The mandril has head, and head is equipped with counterbore, facilitates rotation mandril.
The center chassis is overlapped with the axis in the hole to be processed in valve block to be processed.
The present invention can be portalled in asymmetric valve block by lathe process, guarantee verticality etc. of the hole relative to datum level
Geometric tolerance.Compared with prior art, the hole in valve block can be accurately processed using the present invention, guarantees the hole relative to base
The verticality and precision in quasi- face can accurately process the size and geometric tolerance in required hole in valve block.The present invention
Drilling can be changed to vehicle hole, the machine of improving adds efficiency.Operation of the present invention is easy, and structure is simple, and appearance is small and exquisite, in case of damage
It is bad, it is conveniently replaceable.

Specific embodiment
As shown in Figure 1, the present invention forms 3 by chassis 1, mandril 2, limited block, mandril 2 is screwed in the threaded hole of 1 side of chassis
Interior, there are two slot, a skewed slot, a positive slots for the centre on chassis 1.Push limited block 3 on chassis 1 by being screwed into for mandril 2
Sliding in skewed slot, to lock the valve block 4 placed in the positive slot in chassis 1.Mandril 2 is screwed in the threaded hole on the skewed slot on chassis 1.Limit
Position block 3 slides in the skewed slot on chassis 1.The valve block 4 processed needed for placing in the positive slot on chassis 1 makes to push up by tightening mandril 2
Bar 2 pushes limited block 3, to compress valve block 4.The skewed slot on chassis 1 and the inclined platform of the limited block 3 mutually agree with, and make limited block 3
Inclined platform slided in the skewed slot on chassis 1, thus control to the locking of valve block with loosen.Hole and chassis 1 to be processed in valve block 4
Outer circle is coaxial, and the axis is overlapped with machine tool chief axis, since machine tool chief axis is horizontal, so valve block and the invention are installed
It will not be fallen down due to self gravity after on lathe.The present invention using when only need for valve block to be locked in chassis 1, then should
Invention integral installation directly beats table centering at 1 outer circle of the chassis of the invention in lathe three-claw chuck, thus can be in vehicle
Accurate machining goes out the hole of required processing in valve block 4 on bed, so that vehicle goes out the hole in valve block.
As shown in Fig. 2, the sliding trace line of limited block 3 is overlapped with the diagonal line of rectangle valve block, and side BE is parallel and equal
In side B ' E '；Again because of and when being equal to Q ' E ' parallel in QE；When the point E on limited block 3 is overlapped with the point E ' in valve block 4,
Valve block can be locked in the positive slot on chassis by the side of valve block 4；It is at this time another sliding extreme position of limited block 3.
As shown in Fig. 3,4,5, A, E, J three point on a straight line are the sliding trace line of limited block 3, and because of the skewed slot side on chassis 1
FH is overlapped with the inclined platform side DG of limited block 3, and the skewed slot on chassis 1 PM when NI is with the inclined platform of limited block 3 is overlapped, wherein FH
∥ NI ∥ AJ, so limited block 3 can be free to slide in the skewed slot on chassis 1 along trajectory line AJ.In use, the skewed slot on chassis 1
When FH is with the inclined platform of limited block 3, DG is overlapped, and FH=DG, the skewed slot on chassis 1 PM weight in the inclined platform of NI and limited block 3
It closes, and NI=PM, and because WF ∥ CD, NY ∥ ZP is so when DG and FH are completely coincident, NI and PM has been also at the same time
What full weight was closed, thus at this time CD while with WF, PZ be also fit-state while with NY, as one of limited block 3 is slided at this time
Extreme position.
In use, first valve block 4 is placed in the positive slot on chassis, it is overlapped one side of valve block 4 with the side AW on chassis 1, and make
The another side of valve block 4 is overlapped with the side AY on chassis 1, then tightens mandril 2, and limited block 3 is made to lock valve block 4；It is described to work as 4 quilt of valve block
When locking, four sides of valve block 4 are close in the corresponding sides of chassis 1 and limited block 3, ensure that the fixation of valve block 4 in this way,
So that it will not movements.
