Abstract
The invention relates to a high-precision automatic clamp which comprises a clamp base, a spring outer sleeve arranged on the upper portion of the clamp base, a spring inner sleeve arranged inside the spring outer sleeve, a spring chuck arranged inside the spring inner sleeve, and a positioning core and a cylinder which are arranged inside the spring chuck, wherein the spring outer sleeve is connected with the spring inner sleeve and the spring chuck, the positioning core is connected with the spring chuck, the cylinder is connected with the positioning core, the spring chuck is locked downwards when the positioning core is pulled downwards by the cylinder, and the spring chuck is loosened upwards when the positioning core is pulled upwards by the cylinder. The high-precision automatic clamp has the advantages that the automation degree is high, time for clamping a workpiece is reduced, positioning accuracy is high, the precision of a part machined with the clamp is high with a roundness of 0.3 micrometer and a cylindricity of 1 micrometer, and requirements for high-speed and high-efficiency machining are met.
Description
Technical field
the present invention relates to a kind of High Precision Automatic fixture.
Background technology
at present, of a great variety in the fixture field, but its structure and convenient mounting and clamping degree are uneven, processing for column workpiece is had relatively high expectations to its circularity and cylindricity, though baroque fixture can guarantee the precision of processing, but the more loaded down with trivial details increase operating time of clamping, and convenient mounting and clamping often do not reach required precision.
Summary of the invention
the object of the invention is to provide a kind of High Precision Automatic fixture.
for achieving the above object, the technical solution used in the present invention is:
a kind of High Precision Automatic fixture, comprise clamp base, be arranged on the spring overcoat on described clamp base top, be arranged on the spring inner sleeve of described spring overcoat inside, be arranged on described spring inner sleeve contained spring chuck, be arranged on locating core and the cylinder of described collet inside, described spring overcoat and described spring inner sleeve, collet is connected, described locating core is connected with collet, described cylinder is connected with described locating core, when described cylinder pulls described locating core downwards, described collet is locked downwards, when described cylinder upwards pulls described locating core, described collet upwards unclamps.
preferably, the top of described clamp base is provided with a column, and described spring inner sleeve is connected with described column.
further preferably, described spring inner sleeve is connected with described column by straight pin.
preferably, described spring overcoat is connected by sleeve with described spring inner sleeve; Described spring overcoat is connected by screw thread with described collet.
preferably, described locating core is connected by screw thread with described spring joint.
preferably, described cylinder is connected with described locating core bottom by fastening screw.
because technique scheme is used, the present invention compared with prior art has following advantages and effect:
automaticity of the present invention is high, has reduced the clamping time of workpiece, and positioning precision is high, and the element precision processed is high, can reach circularity 0.3um, and cylindricity 1um meets the requirement of high pin processing at a high speed.
The accompanying drawing explanation
accompanying drawing 1 is structure cross-sectional schematic of the present invention.
wherein: 1, clamp base; 2, spring overcoat; 3, spring inner sleeve; 4, collet; 5, locating core; 6, cylinder; 7, column; 8, straight pin; 9, sleeve; 10, fastening screw.
The specific embodiment
below in conjunction with accompanying drawing and case study on implementation, the invention will be further described:
a kind of High Precision Automatic fixture as shown in Figure 1, comprise clamp base 1, be arranged on clamp base 1 top spring overcoat 2, be arranged on spring overcoat 2 inside spring inner sleeve 3, be arranged on spring inner sleeve 3 contained spring chucks 4, the locating core 5 that is arranged on collet 4 inside and cylinder 6.
in the present embodiment: the top of clamp base 1 is provided with a column 7, column 7 is as the support of whole fixture, left and right arranges, column 7 is connected by straight pin 8 with spring inner sleeve 3, spring inner sleeve 3 is connected with spring overcoat 2 by sleeve 9, and collet 4 is connected on spring overcoat 2 by its external screw thread, thereby forms an integral body, locating core 5 is threaded connection on collet 4, does the workpiece location and uses.Cylinder 6 is connected with locating core 5 bottoms by fastening screw 10.
below the concrete course of work of setting forth lower the present embodiment:
when needs add man-hour, the part of required processing is placed in collet 4, and, by locating core 5 location, now cylinder 6 drive fastening screws 10 move downward, spring overcoat 2 drives collets 4 and moves downward, the locking workpiece; After completion of processing, cylinder 6 drives on fastening screw 10 and moves, jack-up spring overcoat 2, and now collet 4 opens, and unclamps workpiece, completes processing.
above-described embodiment is only explanation technical conceive of the present invention and characteristics, and its purpose is to allow the person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
