Description
Technical field
The present invention relates to a kind of Digit Control Machine Tool, more specifically, it relates to a kind of clamping device and the application device
Walk scheming.
Background technology
Digit Control Machine Tool is a kind of automated machine tool equipped with program control system.The control system can logically handle tool
There are control coding or other symbolic instruction regulated procedures.
At present, Publication No. CN203817861U Chinese patent disclose it is a kind of walk scheming with Y2 axis mechanisms, it
Including lathe bed and Y2 axis mechanisms, wherein, Y2 axis mechanisms are used for the face milling or end face eccentric hole machined at the part back side, the Y2 axles
Mechanism includes the fixed seat being fixedly arranged on away on scheming lathe bed, the slide plate being slidably connected with fixed seat, and is fixedly arranged at the top of slide plate
Unit head, on the lateral surface of unit head it is vertical it is protruding have multiple motorcutters, be used in addition, being additionally provided with fixed seat
The drive component that is moved along Y2 direction of principal axis of driving slide plate, herein, Y2 axles perpendicular to horizontal direction, meanwhile, between fixed seat and slide plate
It is provided with guidance set.
Scheming is simple in construction for this walking with Y2 axis mechanisms, will using scroll chuck in the part of clamping cylinder
The end of part is fixed, in order to avoid axial movement of the part along itself, it is necessary to clamps part, so as to part
Surface there is larger damage.
The content of the invention
In view of the deficienciess of the prior art, the invention reside in a kind of clamping device is provided, by material blocking block to part branch
Support, then contradicted with three elastomer blocks and part, avoid part axial from rotating, damage is caused to piece surface so as to reach to reduce
Purpose.
To achieve the above object, the invention provides following technical scheme：A kind of clamping device, including main shaft and be fixed on
Chuck on main shaft, it is fixed with described chuck for contradicting the material blocking block set with the end of part, on described main shaft
Slidably connect pull bar, be connected with chuck on described chuck, described chuck include the connecting tube being mutually permanently connected and
Three elastomer blocks being used to the outer wall of part contradict uniform along the axial direction of connecting tube, the elastomer block back to connecting tube one
Hold toward away from backgauge Block direction and tilt, described pull bar is threadedly coupled with connecting tube, and described three elastomer blocks are back to part
Side contradicts with chuck and set.
By using above-mentioned technical proposal, between part is placed on into three elastomer blocks, and make the end of material blocking block and part
Portion contradicts, and avoids axial movement of the part along itself, then by by axial movement of the pull bar along itself, driving pull bar
Connecting tube moves, and connecting tube is pulled three elastomer blocks while movement, and is contradicted with chuck, makes three elastomer blocks away from connecting tube
The circular area that is formed of one end reduce, until contradicting the surface of elastomer block and part, produce certain frictional force, due to
Three elastomer blocks do not have to prevent axial movement of the part along itself, so as to make caused by three elastomer blocks and piece surface
Frictional force only needs the axial rotation for avoiding part along itself, so as to effectively reduce the damage to caused by the surface of part
It is bad.
The present invention is further arranged to：Described elastomer block offers stopper slot, described chuck back to the side of part
On be threaded with gag lever post, described gag lever post is placed in stopper slot.
By using above-mentioned technical proposal, because pull bar is threadedly coupled with connecting tube, connecting tube is fixedly connected with elastomer block,
Stopper slot opens up, the problem of can effectively avoiding connecting tube from being separated along the axial rotation of itself with pull bar, so as to be lifted
Job stability.
The present invention is further arranged to：The one end of the elastomer block away from connecting tube is fixed with card-tight part, described clamping
Portion contradicts with chuck and set.
By using above-mentioned technical proposal, the long-term use of elastomer block, certain abrasion can be caused, make three elastomer block shapes
Into a circular diameter become big, part can not be clamped, by the setting of card-tight part, elastomer block can be allowed again by part
Clamp, extend the service life of elastomer block.
The present invention is further arranged to：Described chuck is fixedly connected by terminal pad with main shaft, described terminal pad position
Between chuck and main shaft, described chuck is fixed by the first bolt with terminal pad, and described terminal pad passes through the second bolt
Fixed with main shaft.
By using above-mentioned technical proposal, the setting of terminal pad, chuck can be made to be connected with a variety of main shafts, so as to be lifted
The practicality of chuck.
The present invention is further arranged to：Be in axial sliding connection contiguous block of the described terminal pad along itself, described company
Adapter is connected by the contiguous block with pull bar, and described contiguous block one end is fixedly connected with pull bar, the other end and connecting tube spiral shell
Line connects.
By using above-mentioned technical proposal, pull bar drives contiguous block movement, by the effect of screw thread, drives contiguous block and connects
Adapter movement, because the phenomenon of stripped thread easily occurs in screw thread, now only need replacing contiguous block to be continuing with, be easy to tie up
Repair.
The present invention is further arranged to：Described contiguous block includes first connecting portion and second connecting portion, and described first
Connecting portion is fixedly connected with second connecting portion by the 3rd bolt, and described second connecting portion is threadedly coupled with connecting tube, described
Second connecting portion be fixedly connected with pull bar.
By using above-mentioned technical proposal, when connecting tube and second connecting portion generation stripped thread phenomenon, it is only necessary to change connection
Pipe or second connecting portion, so as to reduce further maintenance cost.
It is another object of the present invention to provide one kind to walk scheming, including a kind of above-mentioned clamping device, passes through backgauge
Block supports to part, then is contradicted with three elastomer blocks and part, avoids part axial from rotating, and reduces so as to reach to piece surface
Cause the purpose of damage.
In summary, the invention has the advantages that：
It is slidably connected by the first supporting part with first connecting portion, the second supporting part is slidably connected with second connecting portion, energy
Error is not likely to produce during the axial movement along pull bar for enough making first connecting portion and second connecting portion, so that second
Connecting portion is not likely to produce error during pulling chuck movement, and when making grips part, part is not susceptible to offset, lifting
The machining accuracy of part.
