Description
Technical field
The invention belongs to the equipment Technology fields of part machinery processing, and in particular to one kind is ground for workpiece planarization
Grip device.
Background technique
In some precision component production processes, need to realize the grinding of part using grinding fixture.Structure is more
The part of rule can use standard vice clamping, and most part shapes are irregular, lack suitable clamping position, centering
Difficulty, it is inconvenient to measure there may be part displacement when directly being clamped with vice, after simultaneous processing, need to take out part and measure, then
When secondary clamping, secondary centering easily causes part size overproof.For check valve class product, valve plate spare part is many kinds of,
Especially vulcanized rubber class valve plate component, due to seal request, surface roughness, flatness and the dimension precision requirement of part
It is more stringent, it is needed after curing using grinding.And External Shape and the machined completion of precision holes, and shape is irregular, zero
The Set and Positioning of part becomes bottleneck, how to realize that sealing surface efficient stable is processed, is to meet element precision and product performance demands
Key point.
Summary of the invention
The object of the present invention is to provide a kind of grip devices for workpiece planarization grinding, are not advised with solving grinding at present
The technical problem that then clamping centering is difficult when part, grinding accuracy is not high.
To solve this technical problem, the technical scheme is that
A kind of grip device for workpiece planarization grinding, the grip device for workpiece planarization grinding includes fixed
Bit position and clamping part, the position portion are made of basic blocks 1 and apotting spindle 2;Clamping part includes screw 3 and pressure
Plate 4;There is groove and step surface, the two sides that step upper surface is located at groove have suitable with 3 phase of screw above the basic blocks 1
The threaded hole matched;The diameter of apotting spindle 2 and the aperture of workpiece are fitted close, apotting spindle 2 and step lower surface, step end face
It fits;There is the hole passed through for screw 3, for compressing apotting spindle 2 on pressing plate 4.
The clamping part also includes vice, is applied in combination with the grip device for workpiece planarization grinding.
The basic blocks 1 are precision machined metal block.
The pressing plate 4 is one piece of integrally formed U-shaped metal platen, the width of U-shaped metal platen and the width of basic blocks 1
Degree is adapted, and two sides position of opening is corresponding with the screw thread hole site of basic blocks 1.
The pressing plate 4 is two pieces of identical metal platens.
The beneficial effects of the present invention are:, using the combination of foundation location block and apotting spindle, being disappeared using the device of the invention
In addition to processing difficulties caused by centering repeatedly, part is quickly and accurately positioned, processing consistency is high.It can be realized work
The quick and precisely clamping of part guarantees positioning accuracy, reduces centering number, improving production efficiency and part processing quality.

Specific embodiment
Detailed description of the present invention is used for the grip device of workpiece planarization grinding with reference to the accompanying drawing:
One, basic structure:
As shown in Fig. 2, the grip device for workpiece planarization grinding of the invention includes position portion and clamping part, institute
The position portion stated is made of basic blocks 1 and apotting spindle 2;Clamping part includes screw 3, pressing plate 4;The basic blocks 1 are
Precision machined metal block, top have groove and step surface, and the two sides that step upper surface is located at groove have suitable with 3 phase of screw
The threaded hole matched;The diameter of apotting spindle 2 and the aperture of workpiece are fitted close, apotting spindle 2 and step lower surface, step end face
It fits;There is the hole passed through for screw 3, for compressing apotting spindle 2 on pressing plate 4.
Pressing plate 4 in this specific embodiment is two pieces of identical metal platens, or one block of integrally formed U-shaped gold
Belong to pressing plate.
When making the device of the invention, 1 baseplane of basic blocks is polished first, then using baseplane as benchmark face, is added
Work goes out step lower plane and step end face, need to ensure the depth of parallelism of two planes and datum level, while should ensure that step end face and platform
Rank lower plane is vertical, finally processes two threaded holes in the step upper surface appropriate location of foundation location block, presses for installation folder
Plate.The size that axis hole is worn according to specific tested parts determines the size of apotting spindle 2, cooperates it with minim gap, positions the heart
The length of axis 2 should be longer than the width of basic blocks.
Two, application method:
When using the present apparatus, mandrel 2 is penetrated in the matching hole of workpiece first, then mandrel is put into basic blocks 1, is put
When setting, pay attention to for mandrel being placed on step baseplane, and be close to step end face, feature bottom plane and step upper surface are pasted
It closes, then pushes down part with pressing plate 4, and tighten 3 fixation clip of screw, then this set of device is put into vice, clamp tiger
Pincers are i.e. processable.
It in grinding process, since workpiece to position completely, therefore does not need to carry out centering again, also due to having pressed when clamping
It tightly, is not in offset phenomena.And mandrel can be directly measured to the distance of processed plane, it need to only ensure mandrel 2 to plane
Center detection can be completed without removing part from grip device away from coincidence pattern tolerance.
Three, implementation result:
When being ground part using the present apparatus, clamping part is increased clamping face, is kept away by the way of pressing plate and vice combination
Displacement or part deformation caused by directlying adopt vice Clamp blocks outer circle are exempted from.
When being ground part using the present apparatus, apotting spindle fits with step end face and step lower plane, limit feature two
The axial movement in a direction and the rotation in three directions amount to 5 freedom degrees, do not need to carry out part manual centering, solve
The problem of centering difficulty.
When being ground part using the present apparatus, clamping efficient quick is not necessarily to centering, that is, can guarantee higher position precision and ruler
Very little precision, and quality stability is good, passing rate of processing is high.
