Abstract
The utility model discloses a kind of scroll chuck fixture for being used to process round thin wall piece, including chuck, it is arranged at the three fan-shaped claws equidistantly distributed on chuck installation end face and around chuck hub, there is arc-shaped convex in the middle part of the sector of the fan-shaped claw, so as to outer step in being formed on sector, flexible cushion is provided with the inner surface and outer surface of the arc-shaped convex.The scroll chuck fixture, by adjusting chuck, using the flexible cushion stress of fan-shaped claw, can large area contact product internal-and external diameter and make uniform force, ensure the size and form and position tolerance of product, effectively protect the surface roughness of product.Without changing other claws again when processing internal-and external diameter respectively simultaneously, in general, the scroll chuck fixture operation is simple, simple in construction, manufacturing cost is low, processing quality is good, high in machining efficiency, and practical value is strong, suitable for large-scale production.
Description
Technical field
The utility model belongs to clamping device technical field, and in particular to a kind of three-jaw card for being used to process round thin wall piece
Plate clamp.
Background technology
Valve seat class product major part belongs to thin wall product, and such product size tolerance is small, circularity requires high, and has table
Face smoothness requirements.Existing processing mode is to utilize clamping with three-jaw chuck, less than normal with product contact area, under stress effect
Product easily produces mistake circle, influences dimensional tolerance and form and position tolerance.And it is steel that the three-jaw of existing scroll chuck, which makes material,
Material, hardness is higher, and easily impression or cut are produced on the surface of product in product clamping process.In converted products respectively
During inside and outside footpath, conventional chuck also needs to positive and negative pawl and changed, and influences processing efficiency.
Utility model content
The purpose of this utility model is that the above-mentioned thin wall product of solution is deformed in process, clamping easily produces
Press cut, change the problem of claw efficiency is low repeatedly, there is provided a kind of scroll chuck fixture for being used to process round thin wall piece, the folder
Tool can make converted products size good with form and position tolerance, not influence product surface roughness, and can be on the premise of claw is changed without
Converted products internal-and external diameter simultaneously.
In order to solve the above technical problems, the technical solution of the utility model is：It is a kind of to be used to process the three of round thin wall piece
Dog chuck fixture, including chuck, it is arranged at three fan-deck cards equidistantly distributed on chuck installation end face and around chuck hub
Pawl, the sector middle part of the fan-shaped claw has arc-shaped convex, so that outer step in being formed on sector, the circular arc
Flexible cushion is provided with shape raised inner surface and outer surface.
Preferably, the flexible cushion is layer of brass.
Preferably, the thickness of the flexible cushion is 2~3 ㎜.
Preferably, the spacing of three fan-shaped claws between any two is 25~30 ㎜.
The beneficial effects of the utility model are：The scroll chuck folder provided by the utility model for being used to process round thin wall piece
Tool, claw use the sector structure with interior outer step, product is increased and uniform force with claw contact surface, so as to effectively protect
Without changing other claws again when demonstrate,proving the size and form and position tolerance of processing, while processing internal-and external diameter respectively, processing effect is significantly improved
Rate.Further, the fixture is also provided with flexible cushion in the contact position of product and claw, effectively protects the surface of product thick
Rugosity, lift product quality.In general, the scroll chuck fixture, manufacturing cost is low, operation is simple, simple in construction, processing effect
Rate is high, processing quality is good, has very strong practical value, is worth popularization in the field of business.
Brief description of the drawings
Fig. 1 is the structural representation that the utility model is used to process the scroll chuck fixture of round thin wall piece；
Fig. 2 is the side elevational cross-section schematic diagram that the utility model is used to process the scroll chuck fixture of round thin wall piece.
Description of reference numerals：1st, chuck；2nd, fan-shaped claw；3rd, flexible cushion.
Embodiment
The utility model is described further with specific embodiment below in conjunction with the accompanying drawings：
As shown in Figures 1 and 2, a kind of scroll chuck fixture for being used to process round thin wall piece of the present utility model, including
Chuck 1 and three fan-shaped claws 2.Three fan-shaped claws 2 are arranged on the installation of chuck 1 end face and equidistant around the center of chuck 1
Distribution.There is arc-shaped convex in the middle part of the sector of fan-shaped claw 2, so that outer step in being formed on sector.Circular arc is convex
Flexible cushion 3 is provided with the inner surface and outer surface risen.
In the present embodiment, when the fan-shaped outer edge of claw 2 overlaps with the outer edge of chuck 1, i.e., do not moved in claw original
Opening position, the spacing of three fan-shaped claws 2 between any two are 25~30 ㎜.Flexible cushion 3 is then soldering in arc-shaped convex
Layer of brass on inner surface and outer surface, its thickness are 2~3 ㎜.Three fan-shaped claws 2 are being installed to the feelings of chuck 1
Under condition, outer step in turning, ensures concentric during clamping product respectively.
By adjusting chuck 1, using the stress of flexible cushion 3 of fan-shaped claw 2, can large area contact product internal-and external diameter and
Make uniform force, ensure the size and form and position tolerance of product, effectively protect the surface roughness of product.Simultaneously respectively inside and outside processing
Without changing other claws again during footpath, in general, the scroll chuck fixture operation is simple, simple in construction, manufacturing cost is low, adds
Work quality better, high in machining efficiency, practical value is strong, suitable for large-scale production.
One of ordinary skill in the art will be appreciated that embodiment described here is to aid in reader and understands this reality
With new principle, it should be understood that the scope of protection of the utility model is not limited to such especially statement and embodiment.
One of ordinary skill in the art can these technical inspirations according to disclosed in the utility model make and various do not depart from this practicality
New substantive other various specific deformations and combination, these deformations and combination are still in the scope of protection of the utility model.
