Abstract
The invention discloses a four-jaw chuck and three-jaw chuck connecting system of a lathe. The system mainly comprises the lathe, wherein the lathe is connected with a four-jaw chuck and one end of the four-jaw chuck, which is far away from the lathe, is connected with a three-jaw chuck. Compared with the prior art, the four-jaw chuck and three-jaw chuck connecting system of the lathe has the following advantages and beneficial effects of providing stable and reliable clamping force, eliminating the trivial process steps of detaching and mounting the four-jaw chuck and saving production input cost.
Description
Technical field
The present invention relates to the clamping device of lathe, specifically be meant lathe four paws folder three-jaw clamping connection system.
Background technology
In the clamping device of lathe, usually can use chuck and scroll chuck.
Scroll chuck is made up of chuck body, movable jaw and claw driving mechanism.On the scroll chuck three claw targeting parts below, there is screw thread to be meshed with the flat thread at the dish-shaped bevel gear back side, when rotating cone pinion by cubic hole with spanner, the dish gear rotates, the flat thread at the back side drive simultaneously three claws to the center near or withdraw from, in order to clamp the workpiece of different-diameter.Be used in and change three anti-pawls on three claws, be used for installing the bigger workpiece of diameter.The accuracy of centering voluntarily of scroll chuck is 0.05-0.15mm.Be subjected to the influence of the chuck accuracy of manufacture and use back abrasion condition with the precision of scroll chuck workpiece.
The reparation of scroll chuck.
It is of a specified duration that scroll chuck uses, and along with bell mouth shape can appear in the wearing and tearing three-jaw of chuck, three-jaw also can slowly depart from the lathe spindle center.The form and position tolerance of institute's processing parts is increased.
Repair the wear problem that three-jaw must solve chuck earlier.Circle is the one of the main reasons that causes the three-jaw centering error big with the gap of central shaft in the dial in the scroll chuck, is that the cylindrical that the chuck dial is rotatably assorted is processed if repair effective method, is tumbling in cover.Make chuck dial and chuck good matched in clearance be arranged greatly about 0.02 the best.Note with the table centering (beat and swing is controlled at 0.01) during chuck in processing
Repairing three-jaw, is example with positive pawl.
Repairing the interior circle of three-jaw must be to add setoff at interior circle, and this needs segmental machining.At first step up a garden ring of getting ready in advance in the outermost end of three-jaw.Hole boring cutter, or adorn a bistrique.By annulus processing three-jaw the inside, top adds a trifle that sets off annulus and stays, and is moving annulus inwards, the processing remainder earlier.The same garden degree that can well guarantee three-jaw so can not form horn mouth yet.(position of three-jaw and chuck must being made marks when noting upper chuck, is that the square hole that makes makes marks at the chucking setoff.Also select to say the square hole that uses in use)
It is big that chuck clamps power, but centering is more time-consuming, so be suitable for the large-scale work of clamping workpiece in irregular shape.The scroll chuck self-centering need not spend the very long time to go for positive part, and clamping efficient is than chuck height, but clamping force there is not chuck big.Be applicable to the more large batch of middle-size and small-size regular part of clamping.Two top clamping work are convenient, do not need centering, clamping precision height.It is high to be applicable to that clamping precision requires, and must pass through work and the more work of operation that multiple clamping just can process.One folder, one top clamping workpiece is safer, can bear bigger axial cutting force.Be applicable to the workpiece that clamping is heavier.
Therefore at the difference of above-mentioned chuck and scroll chuck, the user often adopts chuck of a chassis bed independent setting or scroll chuck in use.Thus, will certainly increase many unnecessary lathes, consider the expensive problem of cost of lathe, therefore need to seek a kind of, on a chassis bed, simple scroll chuck can be installed easily, simultaneously can find accurately fixingly with chuck is disposable, not need scheme the chuck dismounting.
Summary of the invention
The object of the present invention is to provide a kind of lathe four paws folder three-jaw clamping connection system that saves chuck and scroll chuck installation procedure.
Implementation of the present invention is as follows: lathe four paws folder three-jaw clamping connection system, mainly comprise lathe, and described lathe is connected with chuck, and described chuck is connected with scroll chuck away from lathe one end.
Described chuck is provided with at least four gripper jaws away from lathe one end.
Described gripper jaw is evenly distributed on the circumference of chuck and is clamped in the dish body of scroll chuck.
Described chuck sidewall is provided with tightens screw, and the described screw of tightening is connected with gripper jaw.
Described scroll chuck is provided with at least 3 away from chuck one end and holds worker's pawl.
Described scroll chuck sidewall is provided with trip bolt, described trip bolt with hold worker's pawl and be connected.
At said structure, operating procedure of the present invention is.
Steps A, chuck is fixed on the lathe by connector, again centering gradually.
Step B, will tighten screw and unclamp, and the dish body of scroll chuck be sticked in the circle that gripper jaw forms, and will tighten screw-driving, simultaneously with the scroll chuck centering.
Step C, in the time of need carrying out cut workpiece, trip bolt is unclamped, in holding worker's pawl, use trip bolt to tighten, piece-holder simultaneously with the workpiece centering.
Described steps A, step B, step C are useful for clamping precision are required workpiece high, middle-size and small-size regular part.
When needing workpiece machining large, low precision, only need on the basis of steps A, step B, step C, carry out following steps.
Step D, just tighten screw and unclamp, scroll chuck is taken out.
Step e, big workpiece is sticked into gripper jaw, and will tighten screw-driving, simultaneously with big workpiece centering.
On this basis, the user only needs scroll chuck is pulled down or fit on.Carry out replacing of above-mentioned steps, therefore after once mounting is finished chuck, need not dismantle chuck.Exempt the operation that wastes time and energy of the installation centering of chuck.Only need simple scroll chuck is changed.Can satisfy the process requirements of big workpiece and small workpiece.
The present invention compared with prior art has the following advantages and beneficial effect: reliable and stable clamping force can be provided; Cancellation removes and installs the loaded down with trivial details operation of chuck, saves and produces input cost.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Label among the figure is expressed as respectively: 1, tool body; 2, different in nature fixed handle; 3, bare terminal end; 4, clamp groove; 5, trip bolt; 6, cutter.
