Abstract

The invention provides a variable-diameter fixture for a circular ring. The variable-diameter fixture comprises a clamping jaw, a telescopic shaft, a fixing shaft, a small bevel gear, a mounting axle center seat, a rotating hand wheel, a mounting and rotating bracket, a fixing buckle, a ratchet strip, a small tension spring, a large bevel gear and a ratchet. The variable-diameter fixture can be used for clamping, lifting and fixing circular ring heavy objects with different inner diameters and is convenient to use and mount. A self-lock thread transmits a load, inner diameter circular pipe walls of the circular ring heavy objects can be firmly clamped by the aid of the retaining function of the ratchet when the fixture is used, unloading can be realized easily and simply only by poking the ratchet strip and reversely rotating the hand wheel, and the variable-diameter fixture can effectively solve the problem that some tubular heavy objects are difficultly grabbed and fixed.

Description

A kind of annulus reducing jig
Technical field
The invention provides a kind of jig, especially a kind of annulus reducing jig, belongs to the technical field of tooling fixture.
Background technology
Be used for fixing processing object in machine-building process, make it to occupy correct position, to accept the device of constructing or detecting, also known as jig.In a broad sense, any operation in technical process, is used for rapidly, installs easily and safely the device of workpiece, all can be described as fixture.Such as weld jig, inspection jig, assembling jig, jig etc.For pipe class object, sometimes lateral wall can not touch or external diameter too huge, can only be installed internal diameter time, existing jig will have weak point to this.
Summary of the invention
For the problems referred to above, the invention provides a kind of annulus reducing jig, its structure is simple, installs, easy to use, can the internal diameter of quick-clamping pipe class object, and load load is large, distributed uniform, during unloading easily and fast.
The technical solution used in the present invention is: a kind of annulus reducing jig, comprise claw, telescopic shaft, fixed axis, bevel pinion, installation core seat, rotation hand wheel, peace ask frame, fixing buckle, ratchet bar, small extension spring, bevel gear wheel, ratchet, it is characterized in that: described installation core seat is fixedly welded in the center of installation bracket, ensure to install the ask axial line of frame of the axial line of core seat and peace to overlap, a side of installing the bottom surface of core seat and installation bracket is coplanar; Bevel gear wheel is fixedly connected with rotation hand wheel, the central axes of both guarantees; Rotation hand wheel spinning, on the central shaft installing core seat, ensures that rotation hand wheel can rotate by circumference; Fixed axis spinning is in the installing hole of installation bracket, and third level step surface is pressed on the cutting plane in the outside of installation bracket innermost circle, ensures that fixed axis can do circular-rotation in the installing hole of installation bracket; Bevel pinion is fixedly mounted on the minimum footpath axial plane of fixed axis, and adjustment bevel pinion position, makes itself and bevel gear wheel engage each other; Claw spinning does not have screw thread one end at telescopic shaft, and telescopic shaft is installed in the installing hole of installation bracket, and the male end that has of telescopic shaft is connected by threaded engagement with the female end of fixed axis; Ratchet is uniform to be fixed on the lateral surface face of cylinder of rotation hand wheel, and ratchet bar circular hole end is sleeved on the little erection column of installation bracket, and fixing buckle is installed in the aperture of little erection column, guarantees that ratchet bar does not outwards come off; Small extension spring one end is hooked in the dog hole of ratchet bar, and the other end is hooked on the post of installation bracket; The tip of ratchet bar withstands in the ratchet teeth groove of ratchet under the pulling force effect of small extension spring.
Even for realizing load diatibution, intensity of load is enough, and claw, telescopic shaft, fixed axis, bevel pinion are combined together and are provided with four groups.
During for realizing being installed, object not easily landing, the arc surface of claw is provided with anti-slop serrations.
For realize after load can not Self-tipping, the screw thread on the outer axial face of telescopic shaft and the interior axial plane of fixed axis is self-locking thread.
The invention has the advantages that: adopt self-locking thread transmitted load, coordinate ratchet stopping function, can the internal diameter pipe wall of stuck fast annulus class weight in use; Only need lift ratchet bar during unloading, reversing handle can unload, and easily simply, can solve the difficulty that some cast weights are difficult to capture, fix very well.

Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described, is used for explaining the present invention in this illustrative examples of inventing and explanation, but not as a limitation of the invention.
As Fig. 1, Fig. 2, shown in Fig. 3, a kind of annulus reducing jig, after the object that will be installed is determined, the present invention is put into object inner ring, forward rotate rotation hand wheel 6, rotation hand wheel 6 drives ratchet 12 and bevel gear wheel 11 to rotate, bevel gear wheel 11 is rotated by engagement drive four bevel pinions 4, fixed axis 3 is driven to rotate while four bevel pinions 4 rotate, after fixed axis 3 rotates, its internal thread can drive the external screw thread of telescopic shaft 2 to rotate, thus it is protruding to promote four telescopic shafts 2, when firmly dieback is on the inner ring wall of object for four claws 1, stop operating rotation hand wheel 6, simultaneously under the effect of ratchet bar 9, rotation hand wheel 6 is locked, prevent rotation hand wheel 6 rollback and four claws 1 are unloaded voluntarily voluntarily, when needs unload, lift ratchet bar 9, backwards rotation rotation hand wheel 6, under the effect of driving-chain, telescopic shaft is retracted, and load has unloaded.
The present invention uses simply, reliably, can solve the be installed problem of annulus class object when being installed lateral wall well, safe ready, novel unique.
