Spliced pole integrated into one piece is in the both sides of block rubber. The grip block includes grip block main part and base. The utility model discloses fatigue resistance is stronger, cuts more steadily, and the precision that repeats the clamping is higher, and the product quality of machine tooling is more stable better, and elastic rubber block and grip block can the splits, and more convenient the change can not permeated in the oil leak.
Description
Technical field
This utility model relates to the spare and accessory parts of machining apparatus, particularly a kind of caoutchouc elasticity folder
Head.
Background technology
For being arranged on the frock clamp on machining apparatus such as numerically controlled lathe, its function is folder
Clamping of workpieces, the collet that existing frock clamp uses, is the entirety of a metal ring,
Being surrounded by four nugget genus and form, its structure entirety has an elastic waist, when deployed,
Metal ring is overall to be tightened by the tapering on chuck toward post-tensioning thus clamps workpiece, this structure,
Owing to using simple metal toughness to coordinate, and waist is longer, therefore, after repeated use, and its contracting
Tight process has the change of abnormity, such as, asymmetric tightens, so can cause and repeat to make
The problems such as the precision with rear clamping is the highest, and generation repeatable accuracy is bad, impact machining is produced naturally
The quality of product, causes product fraction defective to raise.It addition, existing collet has one relatively
Long waist so that overall structure is the longest, quality is relatively big, so that the bearing capacity of main shaft is relatively
Weight, produced centrifugal force is bigger in the running, so anti-fatigue ability is poor, stable cutting
Property also can be affected.Therefore, it is necessary to the structure of existing chuck is carried out necessary improvement.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of main
The bearing capacity of axle is gentlier, produced in the running centrifugal force is less, anti-fatigue ability is higher,
Cutting is more steady, the precision higher caoutchouc elasticity chuck of repeated clamping.
This utility model solves its technical problem and be the technical scheme is that a kind of caoutchouc elasticity
Chuck, including at least two grip block, described grip block has outside tapering and is circumferentially distributed
Mutually enclosing, grip block is centrally formed through hole after enclosing, and passes through between the most adjacent two grip blocks
One elastic block rubber is connected, and the both sides of described block rubber are equipped with embedded connection post, described
The junction of grip block is provided with the embedded link slot suitable with being connected post, and described block rubber sets
Having central part and cylindrical portion, central part stretches in described through hole, and described cylindrical portion stretches out adjacent two
Outside the cylindrical of individual grip block, it is interference fit between described block rubber with adjacent two grip blocks.
Preferably, described connection post is shaped in the both sides of block rubber.
Improving further, the end face of described grip block is provided with spanner and inserts blind hole.
Concrete, described grip block includes grip block main body and base.
Concrete, the sidewall of described grip block main body is provided with fixing blind hole.
The beneficial effects of the utility model are: owing to passing through a bullet between the most adjacent two grip blocks
Property block rubber is connected, and the both sides of described block rubber are equipped with embedded connection post, described clamping
The junction of block is provided with the embedded link slot suitable with being connected post, during described block rubber is provided with
Heart portion and cylindrical portion, central part stretches in described through hole, and adjacent two folders are stretched out in described cylindrical portion
Hold outside the cylindrical of block, be interference fit between described block rubber with adjacent two grip blocks, so,
When installing workpiece, collet tightens toward post-tensioning tapering in the outer part, tight by elastic block rubber
Contracting provides clamping displacement, and so, the overall structure on the one hand making collet is shorter, quality
Lighter, the bearing capacity of main shaft is less, and the centrifugal force produced during operating is less, so fatigue resistance
Higher, cut more steady；On the other hand elastic block rubber symmetry tightens, and does not have abnormity change,
So the precision of repeated clamping is higher, mach product quality is more stable more preferably, and product is bad
Rate is less.It addition, described grip block passes through the connection that block rubber is removable, after can producing respectively
Assemble again, and be interference fit each other, so the technical process producing elastic block rubber becomes
The simplest, on the one hand that it goes without doing is the biggest for injection mold, saves die cost, and,
One mould injection yield once also considerably increases, and has at least turned over one times, has so been manufactured into
This is lower, and production capacity is higher, and elastic block rubber can split with grip block, more convenient replacing,
Interference fit will not be permeated in leakage of oil, and product quality is more preferable.
Accompanying drawing explanation
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is STRUCTURE DECOMPOSITION schematic diagram of the present utility model.
Detailed description of the invention
With reference to Fig. 1, this utility model one caoutchouc elasticity chuck, including at least two grip block
1, described grip block has outside tapering and being circumferentially distributed and mutually encloses, after grip block encloses
Being centrally formed through hole 2, grip block is shorter, does not has the waist structure for providing elasticity of centre,
Fatigue resistance is higher, and cutting is more steady, by a gum elastic between the most adjacent two grip blocks
Block 3 is connected, and the both sides of described block rubber are equipped with embedded connection post 4, described grip block
Junction be provided with the embedded link slot 5 suitable with being connected post, by elastic block rubber come
Realizing the displacement that tightens between grip block, the precision of repeated clamping is higher, and described block rubber is provided with
Central part 6 and cylindrical portion 7, central part stretches in described through hole, and described cylindrical portion stretches out adjacent
Outside the cylindrical of two grip blocks, join for interference between described block rubber with adjacent two grip blocks
Close.Being interference fit between block rubber with adjacent two grip blocks, meanwhile, central part stretches into institute
Stating in through hole, described cylindrical portion stretches out outside the cylindrical of adjacent two grip blocks, connects post during assembling
4 embed in link slot 5, are so interference fit during guarantee collet integral installation, connect
Closely, waterproof and prevent permeate leakage of oil.
Preferably, described connection post is shaped in the both sides of block rubber, one-body molded, more sharp
In combining closely of connecting, prevent from permeating leakage of oil.The end face of described grip block is provided with spanner and inserts
Blind hole 8, during use, first puts the workpiece in through hole 2, then suitable instrument is inserted spanner
Inserting in blind hole 8, rotation can clamp workpiece；Reverse direction rotates and then can be taken off workpiece.Described
Grip block includes grip block main body 11 and base 12, for collet is fixed on drilling machine or milling
On bed.The sidewall of described grip block main body is provided with fixing blind hole 9, is used for fixing collet.
Additionally, this utility model is not limited to above-mentioned embodiment, as long as it is with essentially identical
Means reach technique effect of the present utility model, all should belong to protection model of the present utility model
Enclose.
