Description
Technical field
The utility model relates to the technical field of metallic machined parts, specifically a kind of clamping ring being fixed on axis.
Background technique
Needing to be arranged clamping ring in the shaft of existing reaction kettle, existing clamping ring is mostly that single metal ring is constituted,
It uses the screw being radially distributed in becket annular wall, realizes that the wall body of becket and axis is fixed.Disadvantage is that
Screw fixing clamp clamp force is often insufficient, and reliability is poor, is easy to fall off in use process, leads to clamping failures；Meanwhile screw
Itself there is certain damage to the wall body of axis.
Utility model content
The technical problems to be solved of the utility model are to provide that a kind of clamping force is larger, reliability preferably clamps
Ring.
In order to solve the above technical problems, the utility model provides the following technical solutions: a kind of clamping ring, including lower ring and be in
The upper ring of open loop, the medial surface of the upper port of the lower ring are in external open circular cone, upper ring include ring body and from
The annular frustum that the ring body extends downwardly；When assembly, the outer peripheral surface of the annular frustum and the circular cone cooperate up and down,
And it is adapted so that the internal diameter of the upper ring is contracted to the internal diameter less than the lower ring, for clamping the axis in upper and lower ring.
Optional scheme is, in the lower ring, the bottom of Yu Suoshu circular cone be equipped with whole step in a ring, to rise
To position-limiting action.
Preferable scheme is that the side of the upper ring is equipped with opening, set on the inner sidewall for having the opposite upper ring that is open with this
Jagged, the use of notch is so that resistance is relatively small when the internal diameter of the upper ring is shunk, convenient for upper annular strain.The size of opening
Depending on the amplitude of required contraction.
Preferable scheme is that multiple installation through-holes being axially distributed are distributed on the ring body of the upper ring, under described
Be distributed on the top surface of ring with screw counter bore corresponding above and below the screw mounting hole, it is logical to pass through the installation using fixing screws
Hole is connect with screw counter bore；Screw in each installation through-hole synchronizes when screwing, and upper ring is along under the circular cone on the lower ring
It moves, while the internal diameter of the upper ring is shunk, so that the upper ring gripping sleeve is set to the axis in the upper and lower ring.
Preferable scheme is that multiple radially-arranged spiral shells are distributed on the side wall of the lower ring, below Yu Suoshu step
Follow closely through-hole.
Preferable scheme is that the outer peripheral surface of the annular frustum is slidably matched with the circular cone in face, in order to control
The amount of moving down of ring in system, and be conducive to control upper ring contraction.
Compared with prior art, the utility model has the beneficial effects that the clamping ring of the utility model, using lower ring and is in
The upper ring of open loop.Upper and lower ring is cooperated up and down by the conical surface, and moves down ring along the circular cone on lower ring using screw,
And the internal diameter of ring is shunk, so that the upper ring gripping sleeve is set to the axis in the upper and lower ring, which makes ring
Hold axis tightly, in the use process of relevant device, upper ring can not loosen, so the reliability clamped is preferable.Upper ring
Clamping force can control the amount of moving down of upper ring by screw to control, and clamping force is larger；Lower ring is finally passed through using screw
Multiple radially-arranged screwing through hole on side wall further fix lower ring with axis.

Specific embodiment
The technical solution of the patent is explained in further detail With reference to embodiment.
Please refer to Fig. 1-5, a kind of clamping ring, including lower ring 2 and in the upper ring 1 of open loop, the upper port of the lower ring 2 it is interior
Side is in external open circular cone 2-1, and upper ring 1 includes ring body 1-1 and the ring extended downwardly from ring body 1-1
Shape frustum 1-2；When assembly, the outer peripheral surface and the circular cone 2-1 or more of annular frustum 1-2 cooperates, and is adapted so that institute
The internal diameter for stating ring 1 is contracted to the internal diameter less than the lower ring 2, for clamping the axis in upper and lower ring.
The lower ring 2 bottom interior, Yu Suoshu circular cone 2-1 is equipped with whole step in a ring, is made with playing limit
With.
The side of the upper ring 1 is equipped with opening 1-3, has the inner sidewall of the opposite upper ring 1 of opening 1-3 to be equipped with notch with this
1-4, the use of notch is so that resistance is relatively small when the internal diameter of the upper ring 1 is shunk, convenient for upper annular strain.The big rootlet of opening
Depending on amplitude according to required contraction.
Multiple installation through-hole 1-5 being axially distributed, the top of the lower ring 2 are distributed on the ring body 1-1 of the upper ring 1
Screw counter bore corresponding with the screw mounting hole 1-5 or more is distributed on face, passes through the installation through-hole using fixing screws
1-5 is connect with screw counter bore；Screw in each installation through-hole 1-5 synchronizes when screwing, and upper ring 1 is along the annular on the lower ring 2
Conical surface 2-1 is moved down, while the internal diameter of the upper ring 1 is shunk, so that 1 gripping sleeve of upper ring is set in the upper and lower ring
Axis.
Multiple radially-arranged screwing through hole 2-2 are distributed on the side wall of the lower ring 2, below Yu Suoshu step.
The outer peripheral surface of the annular frustum 1-2 is slidably matched with the circular cone 2-1 in face, in order to control upper ring
The amount of moving down, and be conducive to control upper ring contraction.
The preferred embodiment of the patent is described in detail above, but this patent is not limited to above-mentioned embodiment party
Formula within the knowledge of one of ordinary skill in the art can also be under the premise of not departing from this patent objective
It makes a variety of changes.
