Abstract
The utility model relates to the technical field of mechanical processing, in particular to a dedicated positioning and tensioning mechanism for expansion sleeves, belonging to clamps. The mechanism comprises a spring sleeve, a spring, a lock nut, a piston cylinder, a clamp body, a positioning block, a taper sleeve, an expansion sleeve and a piston, wherein, the taper sleeve and the piston cylinder are mounted on the clamp body respectively; the positioning block is mounted on the taper sleeve; and when the expansion sleeve is mounted on the taper sleeve, the piston is mounted on the expansion sleeve and is fastened on the expansion sleeve through a lock nut, and the spring is extruded under the lock nut through the spring sleeve. The utility model has benefits of simplified structure, strong clamping force and high precision.
Description
Technical field:
The utility model relates to the Machining Technology field, be specially a kind of special-purpose ringfeder location tensioning mechanism in the anchor clamps.
Background technology:
Present existing processing output shaft of gear-box planet carrier boring jig can't satisfy the processing of many kinds workpiece, and the location clamping is loaded down with trivial details, manufacturing cost is high, can not satisfy the demand of production in enormous quantities, needs a kind of special-purpose ringfeder location tensioning mechanism just can meet the demands.
Summary of the invention:
The utility model provides a kind of special-purpose ringfeder location tensioning mechanism, thereby solves the problem that existing anchor clamps exist.
Technical solution of the present utility model is: a kind of special-purpose ringfeder location tensioning mechanism, comprise spring housing, spring, locking nut, piston cylinder, clamp body, locating piece, tapered sleeve, ringfeder and piston, tapered sleeve, piston cylinder are installed on the clamp body respectively, locating piece is installed on the tapered sleeve, ringfeder is installed in installation piston in back on the tapered sleeve, with locking nut piston is fastened on the ringfeder, spring is squeezed in the locking nut below with spring housing.
The beneficial effects of the utility model are that structure is simplified, clamping force is big, precision is high, cost is low.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Fig. 1 is the utility model structure front section view
The specific embodiment:
As shown in Figure 1, a kind of special-purpose ringfeder location tensioning mechanism, comprise spring housing (1), spring (2), locking nut (3), piston cylinder (4), clamp body (5), locating piece (6), tapered sleeve (7), ringfeder (8) and piston (9), tapered sleeve (7), piston cylinder (4) are installed in respectively on the clamp body (5), locating piece (6) is installed on the tapered sleeve (7), ringfeder (8) is installed in tapered sleeve (7) and goes up back installation piston (9), with locking nut (3) piston (9) is fastened on the ringfeder (8), spring (2) is squeezed in locking nut (3) below with spring housing (1).
Operation principle: hydraulic oil enters piston cylinder (4) promotion piston (9) through clamp body (5) and moves downward, because of piston (9) nut (3) that is locked is fastened on the ringfeder (8), ringfeder (8) is desired to move downward and just is subjected to tapered sleeve (7) crimp clamping work pieces and pulls down workpiece being fitted in above the locating piece (6); When the Hydraulic Station emptying, locking nut (3) is upwards lifted by spring (2), and locking nut (3) drives piston (9) and ringfeder (8) lifts, and ringfeder (8) unclamps workpiece because of no longer being subjected to the extruding spreading of tapered sleeve (7); Different because of the workpiece kind, ringfeder (8) clamped position is made step shape, and φ 100.2, φ 90.8 take into account two kinds as shown in Figure 1.
Claims (1)
1. a special-purpose ringfeder is located tensioning mechanism, comprise spring housing, spring, locking nut, piston cylinder, clamp body, locating piece, tapered sleeve, ringfeder and piston, it is characterized in that, tapered sleeve, piston cylinder are installed on the clamp body respectively, locating piece is installed on the tapered sleeve, ringfeder is installed in installation piston in back on the tapered sleeve, with locking nut piston is fastened on the ringfeder, with spring housing spring is squeezed in the locking nut below.
