Abstract
The invention relates to a two-sided self-centering type clamp. The clamp comprises a shell, a connecting flange, a left taper sleeve, a sandwich, a right taper sleeve and an end cap. The connecting flange connected with a lathe spindle pull rod is coaxially arranged in the shell. The left taper sleeve is coaxially connected with the right side of the connecting flange. The sandwich is coaxially inserted into the right side of the left taper sleeve. The surface, making contact with the left taper sleeve, of the sandwich is a taper surface. A hole used for installation of a workpiece is coaxially formed in the axis of the sandwich. The right taper sleeve is coaxially arranged outside the right side of the sandwich in a sleeving mode. The exterior of the right taper sleeve is coaxially connected with the end cap which is coaxially installed and connected with the shell. The two-sided self-centering type clamp is reasonable in design, simple in structure and convenient to replace and has the self-centering function; and the clamp is firm in clamping force and especially suitable for clamping and machining of stepped shaft type parts with different diameters at the two ends and different tolerances or with large variations. By using the clamp, the machining precision can be improved, and the product quality is ensured.
Description
Technical field
The present invention relates to the clamping tool in machining production technical field, especially a kind of two-sided self-centering type fixture.
Background technology
At present, when using lathe that workpiece is processed, scroll chuck is generally adopted to position.But scroll chuck is relatively suitable for the clamping tubular workpiece with footpath, for the ladder axial workpiece that two ends different-diameter and tolerance are different or variation is bigger, standard scroll chuck is when clamping this series products, owing to clamping diameter portion is fixing, when two (major part or microcephaly) diameter difference change, chucking power can uneven phenomenon, therefore standard three-jaw chuck clamp this series products time easily produce the insecure phenomenon of chucking power, affect machining accuracy.
Summary of the invention
It is an object of the invention to make up the deficiencies in the prior art part, it is provided that a kind of good clamping effect, the work efficiency that can improve, ensure machining accuracy two-sided self-centering type fixture.
It is an object of the invention to be realized by techniques below means:
A kind of two-sided self-centering type fixture, it is characterized in that: include housing, adpting flange, left tapered sleeve, sandwich, right tapered sleeve and end cap, an adpting flange being connected with lathe spindle pull bar it is coaxially disposed in housing, the coaxially connected left tapered sleeve in right side of this adpting flange, internal coaxial one sandwich of plug-in mounting in the right side of this left tapered sleeve, the contact surface of this sandwich and left tapered sleeve is the conical surface, a hole for installing workpiece is coaxially made in the axle center of sandwich, one right tapered sleeve of the right hand external coaxial package of sandwich, this right tapered sleeve outer, coaxial connects end cap, this end cap is co-axially mounted with housing and is connected.
And, a replaceable sleeve jointly it is set with in the outside of left tapered sleeve and right tapered sleeve, this replaceable sleeve is positioned at enclosure interior.
Advantages of the present invention and having the benefit effect that
1, the two ends, left and right of the sandwich of this fixture are inserted into left tapered sleeve and the inside of right tapered sleeve respectively, and the contact surface of this sandwich and left tapered sleeve is the conical surface.When clamping different-diameter (diameter is deteriorated also different) and to ensure multiaxis axiality, very applicable.All stage axle axialities on same axis can ensure within 0.03mm.When each stage external diameter is deteriorated bigger, it is also ensured that identical chucking power.
2, this fixture be suitable for clamping two ends different-diameter and tolerance different or the bigger ladder Machining of Shaft-type Parts of being deteriorated.
3, this fixture has quick-replaceable fixture, quickly remodels, and chucking power is firm, and the advantage that axiality is good can improve production efficiency and ensure processing precision of products after using.
4, the present invention is a kind of reasonable in design, simple in construction, convenient two-sided self-centering type fixture of replacing, this fixture has self-centering function, chucking power is firm, be especially suitable for two ends different-diameter and tolerance different or be deteriorated bigger ladder axial workpiece carry out clamping processing, use this fixture can improve machining accuracy, products quality guarantee.
Accompanying drawing explanation
Fig. 1 is the semi-cutaway of the present invention.
Detailed description of the invention
Embodiments of the invention are described in detail below in conjunction with accompanying drawing；It should be noted that the present embodiment is narrative, it not determinate, it is impossible to limit protection scope of the present invention with this.
A kind of two-sided self-centering type fixture, including housing 2, replaceable sleeve 3, adpting flange 1, left tapered sleeve 4, sandwich 5, right tapered sleeve 6 and end cap 7, an adpting flange being connected with lathe spindle pull bar it is coaxially disposed in housing, the coaxially connected left tapered sleeve in right side of this adpting flange, internal coaxial one sandwich of plug-in mounting on the right side of this left tapered sleeve, the contact surface of this sandwich and left tapered sleeve is the conical surface, a hole for installing workpiece is coaxially made in the axle center of sandwich, one right tapered sleeve of the right hand external coaxial package of sandwich, the contact surface of sandwich and right tapered sleeve is alternatively the conical surface, namely the two ends, left and right of sandwich are inserted into left tapered sleeve and the inside of right tapered sleeve respectively.Jointly be set with a replaceable sleeve in the outside of left tapered sleeve and right tapered sleeve, this replaceable sleeve is positioned at enclosure interior.Right tapered sleeve outer, coaxial connects end cap, and this end cap is co-axially mounted with housing and is connected.
The operation principle of the present invention is:
1, spindle of numerical control lathe pull bar imparts power to adpting flange.
2, adpting flange promotes left tapered sleeve to move right, and extrudes sandwich when left tapered sleeve moves right.
3, the sandwich conical surface and the laminating of left tapered sleeve, together move right, and fit with right tapered sleeve.Right tapered sleeve is fixed cover, and after sandwich two ends and left and right tapered sleeve are fitted completely, the power of moving left and right is changed into radially chucking power, and workpiece 8 is clamped by sandwich.Otherwise unclamp.
Claims (2)
