Abstract
The utility model discloses a three-jaw chuck. The three-jaw chuck comprises a chuck seat and three clamping jaws, wherein through holes are formed in the center of the chuck seat; the three clamping jaws are uniformly arranged on the chuck seat at an angle of 120 DEG in the radial direction of the chuck seat; the front ends of the three clamping jaws are all suspended on the hole surfaces of the through holes and all inwardly recessed arc ends; the arc ends have the same radian; two bolt seats spaced from the three clamping jaws are also detachably connected onto the chuck seat; supporting columns which are connected through screw threads are arranged on the bolt seats; and the extending line of the central line of each supporting column is crossed with the central line of the chuck seat. According to the three-jaw chuck, the three clamping jaws are configured; the arc ends of the front ends of the clamping jaws contact the surface of a lead screw to clamp the lead screw; due to larger surface contact area, the force applied to the lead screw end is larger, so that the lead screw can be effectively clamped; and due to the arrangement of the bolt seats and the supporting columns, the fixation of the lead screw is enhanced, the phenomenon that the lead screw is loosened when processed is avoided and the qualification rate of the processed lead screw is increased.
Description
Technical field
The utility model belongs to field of machining, is specifically related to a kind of scroll chuck.
Background technology
Lathe is the machine that metal blank is processed into machine parts, and it is a machine of making machine, so be called " machine-tool " or " toolroom machine " again, is called for short lathe traditionally, and lathe plays significant role in the construction of national economic modernization.In lathe, need use leading screw production.Need fix leading screw one end in the leading screw processing, leading screw end fixture of the prior art is behind fixing leading screw, and leading screw is prone to slide, and causes the leading screw precision reduction that processes.
Summary of the invention
The utility model technical problem to be solved is the deficiency to above-mentioned prior art, and a kind of scroll chuck is provided, and it can prevent that leading screw from sliding, and strengthens the fixing of leading screw.
The technical scheme that the utility model adopted is: a kind of scroll chuck, comprise dish seat and three claws, and said dish seat center has through hole; Said three claws evenly are arranged on the dish seat by 120 degree; And radially be provided with along the dish seat, three claw front ends all are suspended in the Kong Mianchu of through hole, and the front end of said three claws is the arc end of indent; And the radian of each arc end is identical; Also be removably connected with and three isolated two bolt blocks of claw on the said dish seat, each bolt block is provided with the support column that is threaded, and the extended line of the center line of described each support column intersects with the center line of dish seat.
As preferably, saidly be detachably connected as clamping.
The beneficial effect of the utility model is: the utility model is provided with three claws, and the arc end through the claw front end contacts with the leading screw face to clamp leading screw, because the area of face contact is bigger; Therefore the power that gives the leading screw end is also bigger; Can grasp leading screw effectively, bolt block that is provided with and support column have more been reinforced the fixing of leading screw; Avoid adding the loosening phenomenon of appearance in man-hour, improved the qualification rate of processing.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, dish seat; 2, through hole; 3, claw; 4, arc end; 5, bolt block; 6, support column.
The specific embodiment
To combine accompanying drawing and specific embodiment that the utility model is done further explain below.
Embodiment: as shown in Figure 1, the utility model comprises 1 and three claw 3 of dish seat, and said dish seat 1 center has through hole 2; Said three claws 3 evenly are arranged on the dish seat 1 by 120 degree; And radially be provided with along dish seat 1, three claw 3 front ends all are suspended in the Kong Mianchu of through hole 2, and the front end of said three claws 3 is the arc end 4 of indent; And the radian of each arc end 4 is identical; Also be connected with and three claws, 3 isolated two bolt blocks 5 on the said dish seat 1, each bolt block 5 is provided with the support column 6 that is threaded, and the extended line of the center line of described each support column 6 intersects with the center line of dish seat 1.
The utility model is provided with three claws 3, and the arc end 4 through claw 3 front ends contacts with the leading screw face to clamp leading screw, because the area of face contact is bigger; Therefore the power that gives the leading screw end is also bigger; Can grasp leading screw effectively, the bolt block 5 and the support column 6 that are provided with have more been reinforced the fixing of leading screw; Avoid adding the loosening phenomenon of appearance in man-hour, improved the qualification rate of processing.
