Abstract
The utility model discloses a novel multi jaw independent chuck, which comprises a holding jaw with thread provided on the bottom, chuck body consisting of joint fissions, a holding jaw base, in which is provided slot with the holding jaw and the screw matched with thread on the bottom of the holding jaw, the screw is unmovable in axial direction. Compared with the existing multi jaw independent chuck, the chunk body and the holding jaw base can be manufactured separately, which reduce the difficulty of manufacturing components of a chuck and assembling a chuck, and also the chipping allowance in manufacturing chuck, thereby saving plentiful material cost.
Description
Technical field
The utility model relates to a kind of chuck, relates in particular to the multijaw independent chuck of using on a kind of lathe.
Background technology
In the prior art, the multijaw independent chuck generally comprises the jaw that disk body, several bottom surfaces are provided with screw thread, is provided with groove that passes in and out when clamping and getting loose workpiece for jaw and the screw rod that drives jaw in the disk body.This structure, the structure more complicated of disk body, the assembly difficulty of disk body processing and jaw screw rod is big, and it is huge to add the chipping allowance in man-hour.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of multijaw independent chuck that overcomes the novelty of above-mentioned defective.For this reason, the utility model is by the following technical solutions: it comprises jaw, the bottom surface of jaw is provided with screw thread, it comprises split and the disk body, the jaw seat that connect, be provided with the jaw groove that jaw is set in the jaw seat, also be provided with the screw rod with the threaded engagement of jaw bottom surface in the jaw groove, screw rod is axially not movable at it.Owing to adopt above technical scheme, the utility model is compared with existing multijaw independent chuck, disk body and jaw seat can be processed separately, reduced the manufacture difficulty of chuck part and the assembly difficulty of chuck, and the chipping allowance that has greatly reduced when processing disk body has been saved the great deal of raw materials cost.
Description of drawings
Fig. 1 is the vertical view of a kind of embodiment of the utility model.
Fig. 2 is an A-A cutaway view among Fig. 1.
Fig. 3 is the partial sectional view of side-looking direction embodiment illustrated in fig. 1.
The specific embodiment
With reference to accompanying drawing.The utility model comprises jaw 4, the bottom surface of jaw is provided with screw thread 41, and it comprises split and the disk body 1, the jaw seat 2 that connect, is provided with the jaw groove 21 that jaw is set in the jaw seat, also be provided with the screw rod 3 with the threaded engagement of jaw bottom surface in the jaw groove, screw rod is axially not movable at it.
As shown in Figure 1, in the disk body upper surface 4 jaw seats are set evenly, the jaw groove 21 in the jaw seat along chuck radially.
Be provided with boss 22 in the bottom surface of jaw seat, it cooperates with groove 33 on the screw rod 3, and axially spacing to it at screw rod makes screw rod axially not movable at it, and when rotating screw bolt, its screw thread 31 cooperates with the bottom surface screw thread 41 of jaw, makes jaw slide along the jaw groove.Drawing reference numeral 32 is cubic holes of operation screw rod.
As shown in Figure 3, the jaw seat is connected the upper surface of disk body by bolt 5 and nut 6.The jaw seat also can adopt other multiple modes with being connected of disk body, such as, the jaw seat is welded on the upper surface of disk body.
When assembling, jaw and screw rod are arranged in the jaw seat, again that jaw seat and disk body is fastening, not only on manufacturing process, saved manufacturing cost, more convenient installation simultaneously makes easier for installation, quick.
