Abstract
The invention discloses a clamp special for eccentric parts. The clamp comprises a clamp body, wherein a positioning hole is concentrically arranged on an end surface of the clamp body, and an installation hole is arranged on the other end surface of the clamp body; the installation hole and the positioning hole are not concentric; a plurality of fastening holes are arranged on the surface of the outer circumference of the clamp body; the fastening holes are communicated with the installation hole; annular protrusions are arranged in the installation hole; and the protrusions are arranged in the installation hole with the circle center of the installation hole as the circle center in annular array mode. The clamp special for the eccentric part is easy to manufacture, economical and convenient to clamp, improves the processing accuracy, is suitable for processing production of batch eccentric parts, can ensure processing quality and improves the processing and production efficiency.
Description
Technical field
The present invention relates to a kind of fixture, relate in particular to a kind of processing dedicated clamp for eccentric part, belong to the Machining Technology field.
Background technology
In order to process eccentric part, traditional eccentric processing method has three-jaw cushion block, chuck, floral disc etc.But adopt existing eccentric processing method all to have major defect, efficient is low, and correction time is long.When for example adopting the three-jaw cushion block, need to calculate pad thickness according to formula, then make cushion block; When chuck is got on the bus eccentric element, need first to rule on part, namely find out a circle, guaranteeing the cross hairs of horizontal and vertical direction, in order to determine the position of part in chuck according to these lines.In order to guarantee machining accuracy, installing needs again to carry out after these eccentric locating jigs carefully to proofread and correct for a long time, time-consuming taking a lot of work.Therefore providing the eccentric locating jig that the while easy to use can guarantee precision is the important topic of present precision optical machinery manufacture field.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed the dedicated clamp for eccentric part that a kind of easy while can guarantee precision.
Technical solution of the present invention is achieved in that a kind of dedicated clamp for eccentric part, comprises chuck body, it is characterized in that: be provided with one heart locating hole on described chuck body one end face; Described chuck body other end is provided with installing hole; Described installing hole and locating hole decentraction; Described chuck body external peripheral surface is provided with a plurality of fastener holes; Described fastener hole communicates with installing hole; Establish annular protrusion in described installing hole.
Preferably, described projection is that the center of circle take installing hole is as the inside of center of circle annular array at installing hole.
Preferably, described fastener hole has 3～6.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
A kind of dedicated clamp for eccentric part of the present invention is made simple, economy, convenient mounting and clamping, has improved machining accuracy, is fit to the processing of eccentric part in batches, can guarantee crudy, improves processing efficient.

Wherein: 1, chuck body; 2, locating hole; 3, installing hole; 4, fastener hole; 5, projection; 6, trip bolt.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described.
A kind of dedicated clamp for eccentric part shown in accompanying drawing 1,2 comprises chuck body 1, is provided with one heart locating hole 2 on described chuck body 1 one end faces; Described chuck body 1 other end is provided with installing hole 3; Described installing hole 3 and locating hole 2 decentraction; Described chuck body 1 external peripheral surface is provided with three fastener holes 4; Described fastener hole 4 communicates with installing hole 3; Establish annular protrusion 5 in described installing hole 3; Described protruding 5 be the center of circle take installing hole 3 as the inside of center of circle annular array at installing hole 3, increase the frictional force between installing hole and eccentric part.
As shown in Figure 3, chuck body 1 is arranged on scroll chuck 8, eccentric part 7 is arranged on installing hole 3 inside, the annular protrusion 5 of installing hole 3 inside has increased the frictional force of eccentric part 7 with chuck body 1, make eccentric part 7 be difficult for occuring radial rotating, then fastening bolt 6 is locked eccentric parts 7 by fastener hole 4, further limited the radial and axial movement of eccentric part 7, guarantee machining accuracy, improved crudy.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
A kind of dedicated clamp for eccentric part of the present invention is made simple, economy, convenient mounting and clamping, has improved machining accuracy, is fit to the processing of eccentric part in batches, can guarantee crudy, improves processing efficient.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow person skilled in the art scholar can understand content of the present invention and be implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
