Abstract

The utility model provides a lathe tensioning clamp which comprises a rotating cylinder, a tensioning sleeve, a conical sleeve, a pull rod, a connector and a positioning mandrel. The positioning mandrel is integrated by a pull rod connecting end, a positioning journal, a positioning step and a taper journal in sequence. The conical sleeve is sleeved on the positioning journal. The conical sleeve is opposite to the taper journal. The tensioning sleeve is supported on the conical sleeve and the taper journal. The positioning mandrel penetrates through a guide hole of the connector. The inner end face of the conical sleeve is limited by an end face of the connector. The positioning mandrel is connected with the pull rod through a connecting end of the pull rod. The rotating cylinder is disposed at the rear end of the pull rod. When the lathe tensioning clamp needs to be mounted on a lathe, the connector is mounted firstly, then the tensioning sleeve and the conical sleeve are mounted on the positioning mandrel, the positioning mandrel is connected with the pull rod, the pull rod is connected with the rotating cylinder, the rotating cylinder is connected to the tail end of a spindle of the lathe. By using the rotating cylinder for tensioning, the lathe tensioning clamp is high in work efficiency and constant in tensioning force, and machining quality stability of parts is guaranteed.

Description

A kind of lathe tensioning clamper

Technical field

The utility model relates to the anchor clamps that use at lathe, especially a kind of lathe tensioning clamper with part endoporus location.

Background technology

In order to guarantee the machining accuracy of part on lathe, particularly at the part with the endoporus location, adopt the resilient sleeve tensioning clamper usually.At present, the universal architecture of resilient sleeve tensioning clamper is: be with tapered sleeve at positioning core axle, be with resilient sleeve on the tapered sleeve, manually compress with nut by the threaded ends on the positioning core axle, each thrust is non-constant, causes the crudy instability; In addition, inefficiency.

Summary of the invention

In order to guarantee the stable processing quality of part, increase work efficiency, the utility model proposes a kind of lathe tensioning clamper.

For achieving the goal, the technical solution adopted in the utility model is: a kind of lathe tensioning clamper, comprise rotary cylinder, the tensioner cover, tapered sleeve, pull bar, connector, it is characterized in that: also comprise a positioning core axle, positioning core axle is successively by the pull bar link, locating journal, positioning step, the tapering axle journal constitutes as a whole, tapered sleeve is contained on the locating journal, tapered sleeve and tapering axle journal are arranged in opposite directions, the tensioner cover is supported on tapered sleeve, on the tapering axle journal, positioning core axle passes the pilot hole of connector, the inner face of tapered sleeve is spacing with the end face of connector, positioning core axle is connected with pull bar by the pull bar link, and rotary cylinder is arranged on the rear end of pull bar.

Beneficial effect: when lathe was installed, at first the load joint was contained in tensioner cover, tapered sleeve on the positioning core axle then, and positioning core axle is connected with pull bar, and pull bar is connected with rotary cylinder, and rotary cylinder is connected the lathe spindle tail end again; During use, start cylinder, positioning core axle moves, thus tensioner.The utility model adopts rotary cylinder tensioner, high efficiency; Simultaneously, expanding force is constant, has guaranteed the stable processing quality of part.

Description of drawings

Fig. 1 is structural representation of the present utility model.

The specific embodiment

A kind of lathe tensioning clamper as shown in the figure, comprise rotary cylinder 6, tensioner cover 4, tapered sleeve 3, pull bar 5, connector 1, positioning core axle 2, positioning core axle 2 is successively by the pull bar link, locating journal 2c, positioning step 2b, tapering axle journal 2a constitutes as a whole, tapered sleeve 3 is contained on the locating journal 2c, tapered sleeve 3 is arranged in opposite directions with tapering axle 2a neck, tensioner cover 4 is supported on tapered sleeve 3, on the tapering axle journal 2a, positioning core axle 2 passes the pilot hole of connector 1, the inner face of tapered sleeve 3 is spacing with the end face of connector 1, positioning core axle 2 is connected with pull bar 5 by the pull bar link, and rotary cylinder 6 is arranged on the rear end of pull bar.

When lathe was installed, at first the load joint 1, then tensioner cover 4, tapered sleeve 3 was contained on the positioning core axle 2, and positioning core axle 2 is connected with pull bar 5, and pull bar 5 is connected with rotary cylinder 6, and rotary cylinder 6 is connected the lathe spindle tail end again.
