Abstract
The invention discloses accurate outer support formula chuck, comprise board push rod, support chassis, be arranged on the cylindrical chuck of support chassis top center, it is characterized in that, described chuck side is provided with projection, be several monomers by support chassis and chuck vertical segmentation centered by the center of circle of support chassis, space is provided with between monomer, described support chassis bottom centre is provided with the annular connector connecting each divided support chassis monomer, described board push rod inserts in annular connector, when board push rod exerts a force to support chassis, divided chuck monomer is out of shape from inside to outside and fixes the inside of processed product.Avoid causing damage to the outward appearance of product, can be used for processing the high product of appearance requirement.
Description
Technical field
The present invention relates to a kind of accurate outer support formula chuck.
Background technology
Chuck is also referred to as collet or collet chuck, is the fixture of a kind of a kind of tubular that be used for confine drill bit or milling cutter of device on the process equipments such as milling machine, is a kind of a kind of fixture being used for fixing the part reinforcing needs transformation.Mostly conventional process tools is the chuck of inner clamping type, namely clamp the outer surface of product with jaw, and then carry out various operation to product, this kind of chuck can not process the high product of appearance requirement, because jaw is easy to stay " vestige " at the outer surface of product in operation, cause damage.
The structure of the present invention to existing chuck is improved, and inserts interiors of products by this chuck, to outer support and fixed product, avoids causing damage to the outward appearance of product, can be used for processing the high product of appearance requirement.
Summary of the invention
The object of the present invention is to provide a kind of accurate outer support formula chuck, insert interiors of products by this chuck, to outer support and fixed product, avoid causing damage to the outward appearance of product, can be used for the product that processing appearance requirement is high.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
Accurate outer support formula chuck, comprise board push rod, support chassis, be arranged on the cylindrical chuck of support chassis top center, it is characterized in that, described chuck side is provided with projection, be several monomers by support chassis and chuck vertical segmentation centered by the center of circle of support chassis, space is provided with between monomer, described support chassis bottom centre is provided with the annular connector connecting each divided support chassis monomer, described board push rod inserts in annular connector, when board push rod exerts a force to support chassis, divided chuck monomer is out of shape from inside to outside and fixes the inside of processed product.
Compared with traditional inner clamping type chuck, precision of the present invention outer support formula chuck can insert the inside of processed product, when process equipment actions such as milling machines, board push rod upwards withstand support chassis and to force, because support chassis and chuck are all provided with space, support chassis and chuck have all been divided into some parts of monomers, and (chuck portion after segmentation is still connected in the support chassis of segmentation, support chassis is linked together by the annular connector of bottom, therefore they or an entirety), therefore the center of support chassis can be out of shape and is upturned, and then drive the distortion of chuck, the top of chuck will slowly outwards strut, acquire a certain degree and just can fix the inside of processed product, and outward appearance towards processed products can not cause any infringement.When process equipment stops action, board push rod can not exert a force to support chassis, and chuck has also just recovered original state, just processed product can be taken out.
The invention has the beneficial effects as follows: flexible structure, insert interiors of products by this chuck, to outer support and fixed product, avoid causing damage to the outward appearance of product, can be used for processing the high product of appearance requirement.
Accompanying drawing explanation
Fig. 1 is the structure chart of precision of the present invention outer support formula chuck;
Fig. 2 is the side view of Fig. 1;
The mark implication of accompanying drawing is as follows:
1: support chassis; 2: chuck; 3: board push rod; 4: annular connector; 5: space; 6: protruding.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, technical solution of the present invention is described in further detail, can better understand the present invention to make those skilled in the art and can be implemented, but illustrated embodiment is not as a limitation of the invention.
As shown in Figure 1 and Figure 2, accurate outer support formula chuck, comprise board push rod 3, support chassis 1, support chassis 1 top center is provided with cylindrical chuck 2, and the height of preferred chuck 2 is 0.5-2 times of chuck 2 diameter.Chuck 2 side is provided with protruding 6, it is a kind of circular protrusions 6 along chuck 2 side in figure, preferred protruding 6 is silica gel materials, when fixing processed product and being inner, can reduce and firm effect is strengthened to the infringement of interiors of products simultaneously, prevent landing, certainly protruding 6 also can adopt the duplicate material of same chuck 2, or chuck 2 adopts the method for inlaying soft alloy or the method adopting cover rubber ring to increase anti-skidding damping to realize being effective.Be several monomers by support chassis 1 and chuck 2 vertical segmentation centered by the center of circle of support chassis 1, space 5 is provided with between monomer, namely the space of chuck 2 covers on the space of support chassis 1, that is, support chassis 1 and chuck 2 are not a complete whole solid entirety, and be all divided into several monomers, each chuck monomer after divided and support chassis monomer are a little entirety, and these each combination of monomers divided constitute support chassis 1 with space and chuck 2 together.In figure, the space 5 of support chassis 1 and chuck 2 is all the spaces 5 in " ten " font, and also can be arranged to the space 5 in " rice " font, generally speaking, the quantity in space 5 is more, and the degree that chuck 2 is out of shape is also larger.Center bottom support chassis 1 is also provided with annular connector 4, for connecting the support chassis monomer after each segmentation, still be connected to bottom chuck 2 after segmentation in the support chassis 1 of segmentation, support chassis 1 is linked together by the annular connector 4 of bottom, therefore they or an entirety.
Board push rod 3 one end is connected on process equipment, such as milling machine, the other end inserts in the cavity formed between annular connector 4 and support chassis 1 center, outer for precision support formula chuck 2 is inserted the inside of processed product, when process equipment action, board push rod 3 upwards withstand support chassis 1 and to force, because support chassis 1 and chuck 2 are all provided with space 5, support chassis 1 and chuck 2 have all been divided into several monomers, therefore the center of support chassis 1 can be out of shape and is upturned, and then drive the distortion of chuck 2, the top of chuck 2 will slowly outwards strut, acquire a certain degree and just can fix the inside of processed product, and outward appearance towards processed products can not cause any infringement.When process equipment stops action, board push rod 3 can not exert a force to support chassis 1, and chuck 2 has also just recovered original state, just processed product can be taken out.
These are only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in the technical field that other are relevant, be all in like manner included in scope of patent protection of the present invention.
