Abstract
The invention discloses a chuck structure of a three-claw interlocking heavy horizontal lathe, which comprises a chuck body, three driving claws evenly distributed along the chuck body and a driving mechanism for driving the chuck, wherein, each driving claw is respectively provided with an identical driver used for driving the claw to make clamping and relaxing motion; the driving mechanism of the driver is a bevel gear and the driver is arranged on the bevel gear; and the bevel gear is installed on a machine tool spindle. Compared with the prior art, the three-claw interlocking mechanism of the chuck with a big diameter is adopted. At present, only the chuck with diameter being equal to or less than 1 m is provided with three claws for interlocking in China; and the machine tool has the obvious advantages for processing the large-size pipe parts: firstly, an auxiliary flange plate tool is not required; secondly, the chuck is provided with 6 claws altogether, wherein, the three claws are interlocked for self centering, the other three claws are helpful for clamping, and the clamping force ensures the central lines of the three workpieces to be fully coincided with the central line of the machine tool so that the machining precision is high; thirdly, the efficiency is high, both the headstock chuck and the tailstock chuck adopt the structure and are just required to be installed and clamped without alignment; and fourthly, the structure is simple and the processing is easy.
Description
Technical field
The present invention relates to a kind of three-claw interlocking heavy horizontal lathe, relate in particular to a kind of chuck structure of three-claw interlocking heavy horizontal lathe.
Background technology
Along with fast development of national economy, domestic processing to large-size pipe is precise treatment day by day, and traditional process is only adopted in domestic processing at this type of part at present, and cut after using the flange tailstock to hold out against at two ends.Have following shortcoming: 1, precision is not high.Because the center that the head of a bed and tailstock hold out against is ring flange centers, two ends, be not workpiece real center line, only be approximation.2, the ring flange amount is required greatly.The pipe fitting that changes a kind of specification just needs the workpiece ring flange.3, efficient is low, is installed back and forth, and ring flange is long non-cutting time.
Chinese patent 200620101635.1 discloses a kind of scroll chuck, its structure is rotated small conical gear for to come transmission by parcel with spanner, drives large conical gear and rotates, thereby drive the planar rectangular screw thread at the large conical gear back side, drive three-jaw then and entad move.Above-mentioned patent exists clamping force deficiency, cost height, baroque problem.
Summary of the invention
At the deficiencies in the prior art, technical problem to be solved by this invention is, a kind of chuck structure of three-claw interlocking heavy horizontal lathe is provided, with solve clamping force deficiency, cost height, precision is low, cost is high and baroque problem.
1, for solveing the technical problem, the technical solution used in the present invention is: a kind of chuck structure of three-claw interlocking heavy horizontal lathe, by disk body, along disk body uniform three initiatively the claws driving mechanism that is used for drive chuck constitute, described each initiatively claw identical being used to all be set drive the lead agency that claw is done chucking and relaxing exercise; The driving mechanism of described lead agency is a bevel gear, and lead agency is arranged on the bevel gear; Described bevel gear is installed on the machine tool chief axis.
The chuck structure of above-mentioned three-claw interlocking heavy horizontal lathe, its disk body are provided with three auxiliary claws that are used to guarantee clamping force; The independently manual lead agency of its auxiliary claw setting.
The chuck structure of above-mentioned three-claw interlocking heavy horizontal lathe, it drives three, and initiatively claw is identical with the lead agency of three auxiliary claws; Its lead agency is to constitute leading screw screw structure by screw mandrel and the master jaw that combines with leading screw; Its leading screw is provided with the gear that matches with lead agency with the inner end of lead agency combination, and the outer end is provided with handle.
The present invention has compared with prior art adopted the three-claw interlocking mechanism of major diameter chuck.At present, the domestic 1m of only limiting to is to have three-claw interlocking on the interior chuck.It is with the obvious advantage to process this lathe for large-scale pipe type element: 1, need not auxiliary flange dish frock; 2, chuck totally 6 pawls, the three-claw interlocking self centering, the auxiliary chucking of three-jaw guarantees that three clamping forces guarantee that three workpiece centres overlap fully with machine axis, makes the machining accuracy height.3, efficient height, head of a bed chuck and tailstock chuck all adopt this structure, need not centering back and forth, chucking is installed is got final product.4, simple in structure, handling ease.
Description of drawings
Fig. 1 is the structural representation of the chuck structure of three-claw interlocking heavy horizontal lathe of the present invention;
Fig. 2 is the A-A cutaway view of the chuck structure of three-claw interlocking heavy horizontal lathe of the present invention;
Fig. 3 is the B-B cutaway view of the chuck structure of three-claw interlocking heavy horizontal lathe of the present invention.
The specific embodiment
The present invention is described in more detail below in conjunction with accompanying drawing and embodiment.
As Fig. 1, the chuck structure of this invention three-claw interlocking heavy horizontal lathe, by disk body 1, along disk body uniform three initiatively claws and the driving mechanism that is used for drive chuck constitute, each initiatively claw identical being used to all be set drive the lead agency that claw is done chucking and relaxing exercise.The driving mechanism of lead agency is a bevel gear 2, and lead agency is arranged on the bevel gear 2.Bevel gear 2 is installed on the machine tool chief axis.Also be provided with three auxiliary claws that are used to guarantee clamping force on the disk body.The independently manual lead agency of its auxiliary claw setting, initiatively claws are identical with the lead agency of three auxiliary claws to drive three; Its lead agency is to constitute leading screw screw structure by screw mandrel 3 and the master jaw 4 that combines with leading screw.Leading screw is provided with the gear that matches with lead agency with the inner end of lead agency combination, and the outer end is provided with handle 5.
Machine tool chief axis drives main axis rotation by the lathe transmission mechanism, be equipped with bevel gear on the main shaft, can on top, rotatablely move, be rotated thereby drive three active leading screws, thereby drive the master jaw motion that combines with leading screw, master jaw and then drive claw tighten workpiece simultaneously.The handle of rotating threaded shaft outer end unclamps leading screw successively, and then workpiece is unclamped.
The present invention is applicable to being installed of part of no centre bore.Main axis rotation also drives chuck and rotates together, drives workpiece behind the chuck chucking workpiece and together rotates, and carries out turning.Head of a bed chuck and tailstock chuck all adopt this structure, need not centering back and forth, chucking is installed is got final product.Following 3 of principles centers.Characteristics: simple in structure, handling ease, effect is excellent.
