Abstract
The invention relates to a shaft workpiece clamping device which is characterized by comprising a jacking tip, a blade base and a connecting disc, wherein the connecting disc is fixedly connected with the bottom of the blade base; the blade base is internally provided with a spring mounting cavity in the lower part and a jacking tip mounting cavity in the upper part; the jacking tip is assembled inside the jacking tip mounting cavity in an axial moving manner; the length of the jacking tip is largerthan that of the jacking tip mounting cavity and is smaller than the sum of the lengths of the jacking tip mounting cavity and the spring mounting cavity; the spring mounting cavity is internally provided with a spring; two ends of the spring are respectively proppedagainstthe bottom of the jacking tip and the connecting disc. The shaft workpiece clamping device can be used for effectively clamping a workpiece, is high in workpiece clamping precision, and simple and convenient in clamping process, and the workpiece can be still clamped even when the clamping part of the workpiece is not sufficient.
Description
Technical field
The present invention relates to a kind of shaft-like workpiece clamping device.
Background technology
The existing fixture for clamping axial workpiece generally adopts top location, and utilize opening sleeve or the clamping of claw location, although the shaft forgings fixture of this structure can meet the demand of shaft forgings location processing to a certain extent, but also there is defect: when 1, adopting existing opening sleeve or jaws clamp, workman requires great effort very much, sometimes not clamping; 2, in clamping process, workpiece may depart from center, causes mismachining tolerance; 3, the workpiece had does not have enough retaining parts, needs to do technique and lengthens, thus cause operation to increase, lower efficiency.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of technical scheme of shaft-like workpiece clamping device.
Described a kind of shaft-like workpiece clamping device, it is characterized in that comprising top, edge of a knife seat, be fixedly connected on terminal pad bottom described edge of a knife seat, the spring fitting chamber being positioned at bottom and superposed top installation cavity is provided with in described edge of a knife seat, describedly toply axially movably be assemblied in described top installation cavity, and top length is greater than the length of described top installation cavity, and be less than the length sum in described top installation cavity and spring fitting chamber, be provided with spring in described spring fitting chamber, described both ends of the spring is resisted against between described top bottom and terminal pad respectively.
Described a kind of shaft-like workpiece clamping device, it is characterized in that described top bottom is provided with loop bar, described spring housing is contained on described loop bar.
Described a kind of shaft-like workpiece clamping device, is characterized in that the top end face of described edge of a knife seat is provided with the edge of a knife of at least two uniform settings ringwise.
Described a kind of shaft-like workpiece clamping device, is characterized in that the described edge of a knife is strip, and the bearing of trend of the described edge of a knife is positioned at described top installation cavity in the radial direction.
Described a kind of shaft-like workpiece clamping device, is characterized in that described edge of a knife cross section is trapezoidal, and the wide 0.1-0.2mm in the top of the edge of a knife.
The present invention can not only clamping work pieces effectively, and clamping workpiece precision is high, and clamping process is easy, even if when workpiece does not have enough retaining parts, also can realize clamping.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with Figure of description, the present invention will be further described:
Shaft forgings fixture, comprise top 1, edge of a knife seat 2, be fixedly mounted on the terminal pad 3 bottom described edge of a knife seat 2 by bolt 8, the spring fitting chamber 4 being positioned at bottom and superposed top installation cavity 5 is provided with in described edge of a knife seat 2, described top 1 is axially movably assemblied in described top installation cavity 5, and the length of top 1 is greater than the length of described top installation cavity 5, and be less than the length sum in described top installation cavity 5 and spring fitting chamber 4, spring 6 is provided with, bottom described spring 6 two ends are resisted against described top 1 respectively and between terminal pad 3 in described spring fitting chamber 4.Preferably, be provided with loop bar bottom described top 1, described spring 6 is sleeved on described loop bar, is convenient to spring 6 and extends and compress.Terminal pad 3 is arranged on lathe, top 1 is placed in the centre bore on workpiece 7, by the positioning and clamping between top 1 and centre bore, effectively can improve the clamping precision of shaft-like workpiece 7, and do not need prefabricated sufficiently long retaining part on workpiece just can realize clamping, simple and convenient, operation easy to implement.The length of top 1 is set to the length being greater than top installation cavity 5, and be less than the length sum in top installation cavity 5 and spring fitting chamber 4, make top 1 under action of hydraulic force Compress Spring 6, the upper surface of edge of a knife seat 2 and workpiece 7 end face are fitted tightly, by the frictional force between workpiece 7 and edge of a knife seat 2, make workpiece 7 can bear certain moment of torsion.
Therefore, it is inadequate that this shaft forgings fixture efficiently solves workpiece 7 clamping length, needs the problem that the cost doing technique lengthening and increase operation increases, and do not cost power during clamping, only need workman's righting before upper top pressure; Owing to adopting Double Tops point location, consistent with benchmark when detecting, positioning precision is high, and tooth runout can ensure in 0.012mm in batches; The versatility of this shaft forgings fixture is good, does not need to do special jaw, the applicable diameter of axle in a big way, and can be used for the operation such as turning and Milling Process of axial workpiece.
The top end face of edge of a knife seat 2 is provided with the edge of a knife of at least two uniform settings ringwise, by arranging the edge of a knife, workpiece 7 is under action of hydraulic force, Compress Spring 6, the edge of a knife is embedded in workpiece 7 end face, make workpiece can transmit larger moment of torsion, be convenient to the machined of workpiece, edge of a knife seat 2 upper surface of the present embodiment is provided with the uniform edge of a knife of 6 annulars.Preferably, the described edge of a knife is strip, and the bearing of trend of the described edge of a knife is positioned at described top installation cavity 5 in the radial direction, can strengthen the stress performance of the edge of a knife, makes the edge of a knife can bear larger cutting force.Preferably, described edge of a knife cross section is trapezoidal, and the wide L=0.1-0.2mm in the top of the edge of a knife, the edge of a knife can be embedded into smoothly in workpiece 7 under action of hydraulic force, make can bear larger moment of torsion between workpiece 7 and the edge of a knife.
