Description
Technical field
The utility model relates to a kind of chuck, particularly about a kind of self centering scroll chuck.
Background technology
At present on vertical lathe during processing vehicle wheel hub bore, when perhaps processing the hole of other disc type part, usefulness be that chuck is installed entirely, need artificial centering when chuck is installed, and then clamp.If wanting four claws can both coordinate centering, this will spend long time, and it is inaccurate to feel relieved, and so just causes labour intensity big, inefficiency.
Summary of the invention
At the problems referred to above, the purpose of this utility model be propose a kind of can self centering scroll chuck.
For achieving the above object, the utility model is taked following technical scheme: a kind of self-centering scroll chuck, it is characterized in that: it is provided with a chassis that is installed on the lathe, a minor axis is fixed at the place at described center chassis, described minor axis exposes a sheathed rotating disk on the position on chassis, on the card on described chassis, be fixed with three covers and clamp a mechanism and a cover tensioning mechanism, each described clamp mechanism includes a clamping seats, a clamp and a connecting rod, described clamping seats is fixed on the chassis, and exceed described rotating disk, the end face of each described clamping seats is concordant; Radially offer a chute on chassis, described clamping seats upper edge, described clamp is slidingly arranged in the chute, and described clamp exceeds described clamping seats, an end of the inboard hinged described connecting rod of described clamp, and the other end of described connecting rod is connected on the described rotating disk by wearing pin; Described tensioning mechanism comprises a leading screw supporting seat, a leading screw, a feed screw nut and a Cardan shaft, described leading screw supporting seat is fixed on the chassis, described leading screw is rotatably provided in the described leading screw supporting seat, the sheathed described feed screw nut in the outer end of described leading screw, the inner of described leading screw is connected to described rotating disk by Cardan shaft.
Being lower than described clamping seats, being higher than described rotating disk place, a scrap catch tray is set.
The utility model is owing to take above technical scheme, it has the following advantages: 1, the utility model is provided with a cover tensioning mechanism and three cover clamping mechanisms, pulling by tensioning mechanism, drive the clamp mechanism clamping work pieces, because three covers clamp mechanism and tighten up simultaneously, therefore centering simultaneously, accurate positioning.2, the tensioning mechanism center is to adopt a leading screw, utilizes the precession of leading screw or screw out to drive central turnplate rotation, is connecting tensioning mechanism on the rotating disk simultaneously, so can spur tensioning mechanism during dial rotation and tighten up or loosen.Therefore 3, the clamp of connecting rod and slip mainly is set on the tensioning mechanism, and connecting rod is connected on the rotating disk, connects clamp on the connecting rod again simultaneously, and when dial rotation, clamp moves to the center can clamping work pieces, outwards mobilely can unclamp workpiece.4, tensioning mechanism and clamp mechanism operation principle are all comparatively simple, by the chassis the utility model are installed in above the former vertical lathe, and former lathe is not done any change, and only installation just can be used after adjusting, and operating efficiency is significantly improved.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1, the utility model is mounted in above original lathe chassis, and it comprises a chassis 1, and chassis 1 is fixed on the original chassis of lathe by bolt 2.The center on chassis 1 has an axis hole, is inserted with a minor axis of attaching the names of pre-determined candidates 3 in axis hole, on the part on minor axis 3 exposes chassis 1, is arranged with a rotating disk 4, and rotating disk 4 can rotate on minor axis 3 during the application of force.
On the card on chassis 1, there are three covers to clamp a mechanism 5 and a cover tensioning mechanism 6 by bolting.Here because clamp mechanism 5 is three, during clamping work pieces, clamp mechanism 5 is tightened up as three claws, so the utility model is referred to as scroll chuck.All include clamping seats 51, clamp 52 and connecting rod 53 on each clamp mechanism 5, wherein clamping seats 51 is fixed on the chassis 1, and is higher than rotating disk 4.The end face of three clamping seats is all level and smooth and be maintained at the same horizontal plane.Middle part at clamping seats 51 radially offers a chute along the chassis, clamp 52 is slidingly arranged in the chute, and clamp 52 exceeds the end face of clamping seats 51.At clamp 52 on a side of 1 inboard, chassis, articulated linkage 53, the other end of connecting rod 53 is connected on the rotating disk 4 by the pin of wearing that is arranged on rotating disk 4 edges.
For tensioning mechanism 6, it comprises a leading screw supporting seat 61, leading screw 62, feed screw nut 63 and Cardan shaft 64.Leading screw supporting seat 61 is fixed on the chassis 1, rotary setting one leading screw 62 in leading screw supporting seat 61, and the outer end fixed cover of leading screw 62 is provided with feed screw nut 63.Pull feed screw nut 63 with spanner and just can make leading screw 62 precession or back-out in leading screw supporting seat 61.At the other end of leading screw 62, be connected to wearing in the pin of rotating disk 4 edges by Cardan shaft 64.
When precession leading screw 62, leading screw 62 will promote rotating disk 4 and rotate, and the rotation of rotating disk 4 will spur three connecting rods 53, causes three clamps 52 to tighten up self-centering to center chassis simultaneously.If workpiece is placed into the inboard of the upper clamping block 52 of clamping seats 51, when clamp 52 tightens up inwards, will fastens workpiece.
On chassis 1, crossed over clamp mechanism 5 and tensioning mechanism 6, mask rotating disk 4, and be lower than clamping seats 51 (promptly below workpiece), one scrap catch tray 7 is set,, backs out clamp 52 when the workpiece completion of processing, after taking out workpiece, can take out scrap catch tray 7, reclaim scrap.
The utility model is not done any change to former lathe, just can use after only install adjusting, if do not need the utility model, pulls down and gets final product.
