Abstract
The utility model discloses a kind of inner support clamp, including outer cylinder body, described outer cylinder body has the inner chamber that left and right is penetrating, is provided with an apical axis that can move left and right in this inner chamber, and the right part of this apical axis has bullet, simultaneously, the right side of this outer cylinder body is provided with at least 3 pivots, and those pivots are all articulated with a support member, and, pivot is positioned at a sidepiece of corresponding support member, and medial surface and the bullet of another sidepiece of support member match.The utility model has the advantages that: can the inwall of preferable nip cylinders shape workpiece, and uniform force.
Description
Technical field
The present invention relates to technical field of tooling clamps, especially relate to a kind of inner support clamp.
Background technology
In fields such as machinings, it usually needs its outer surface is processed by clamping cylindrical work pieces.Such as, fixture is passed through
Clamping glass cylinder, then while heating glass infuser, carries out pressurizing and deformation to glass infuser, makes the glass systems such as thermos cup
Product.Now, optimal mode is to be clamped the inside of cylindrical work pieces by fixture.At present, the clip-like used is equal
Complex, the most convenient during use.
Summary of the invention
It is an object of the invention to provide a kind of inner support clamp, it has can the inwall of preferable nip cylinders shape workpiece
Feature.
The technical solution adopted in the present invention is: inner support clamp, and including outer cylinder body, it is penetrating that described outer cylinder body has left and right
Inner chamber, is provided with an apical axis that can move left and right in this inner chamber, the right part of this apical axis has bullet, meanwhile, and this outer cylinder body
Right side is provided with at least 3 pivots, and those pivots are all articulated with a support member, and, pivot is positioned at corresponding support member
A sidepiece, medial surface and the bullet of another sidepiece of support member match.
Described apical axis Luo is connected on this interior intracavity.
Described support member is provided with back-moving spring.
The present invention is the most advantageously: can the inwall of preferable nip cylinders shape workpiece.This
The inner support clamp of invention is in use, it is only necessary to driving apical axis to move right, the side of support member i.e. can be strutted, quite by bullet
It is collectively forming cylindrical external diameter in the outer rim making all support members to increase, it is simple to hold out against the inwall of cylindrical work pieces to cylindrical work pieces
Clamped, extremely convenient.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings:
Fig. 1 is the front sectional view of embodiments of the invention；
Fig. 2 is the right view of Fig. 1.
Detailed description of the invention
Embodiment, as shown in Fig. 1 and Fig. 2: inner support clamp, including outer cylinder body 10.In use, this outer cylinder body 10 is fixed on
On the axle of process equipment.
Further saying, this outer cylinder body 10 has the penetrating inner chamber in left and right 11.This inner chamber 11 is provided with one can move left and right
Dynamic apical axis 20, the right part of this apical axis 20 has bullet 21.In the present embodiment, this apical axis 20 Luo is connected in this inner chamber 11.With
Time, the right side of this outer cylinder body 10 is provided with at least 3 pivots 30.Obviously, those pivots 30 move towards along left and right.Those pivots 30
On be all articulated with a support member 40.And, pivot 30 is positioned at a sidepiece of corresponding support member 40, another of support member 40
Medial surface and the bullet 21 of sidepiece match.Such as, pivot 30 is positioned at the reverse finger side on corresponding supporter 40, and support member
The side clockwise of 40 withstands on the bullet 21 of this apical axis 20 near the side of this apical axis 20.So, once this apical axis 20 is to the right
Mobile, then those support members 40 i.e. can rotate around corresponding pivot 30 thus the cylinder that is collectively forming of the outer rim of support member 40
Diameter can increase, the fabulous inwall holding out against cylindrical work pieces, to cylindrical work pieces formed clamping, in order to outside to cylindrical work pieces
Surface or end are processed；Otherwise, this apical axis 20 is moved to the left, then those support members 40 i.e. can be anti-around corresponding pivot 30
The cylindrical diameter being collectively forming to rotation thus the outer rim of support member 40 can reduce, it is simple to takes off workpiece.
Optimizing, support member 40 is provided with back-moving spring 50.Such as, connect between adjacent support member 40 and have extension spring.This
Sample, makes those support members 40 lean against closely on the bullet 21 of this apical axis 20.
The foregoing is only the preferred embodiments of the present invention, not thereby limit the scope of the claims of the present invention, every utilization
Equivalent structure or equivalence flow process that description of the invention and accompanying drawing content are made convert, or it is relevant to be directly or indirectly used in other
Technical field, be the most in like manner included in the scope of patent protection of the present invention.
