Abstract
The invention provides an improved type reinforcing screw rod type heavy-duty four-jaw independent chuck, which can realize reasonable selection of workpiece clamping force under different working requirements and solve the problem of insufficient clamping force when loaded with a heavy type workpiece. The improved type reinforcing screw rod type heavy-duty four-jaw independent chuck comprises a chuck body, a pressure block, four jaws and screw rods, wherein the pressure block is positioned on a central position on the surface at one end of the chuck body; and one end of the chuck body is provided with the four jaws. The improved type reinforcing screw rod type heavy-duty four-jaw independent chuck is characterized in that the screw rods are reinforcing screw rods; the four jaws are connected with corresponding reinforcing screw rods respectively; and the reinforcing screw rods are supported on the chuck body.
Description
(1) technical field
The present invention relates to the machining frock, be specially improved type reinforced leadscrew type heavy-load four-jaw independent chuck.
(2) background technology
Existing four-jaw chuck, its clamping force is big inadequately, particularly during the big specification heavy workpiece of clamping, because clamping force is big inadequately, easily causes workpiece clamp not firm, machining accuracy difference and easily causing danger; And during holding workpiece, because the simple workman of dependence passes through the spanner clamping, its labour intensity is big.
(3) summary of the invention
At the problems referred to above, the invention provides a kind of improved type reinforced leadscrew type heavy-load four-jaw independent chuck, it can realize the choose reasonable of workpiece clamping force under the different operating requirement, the problem of insufficient clamping force when solving the carrying heavy workpiece.
Its technical scheme is such: it comprises disk body, briquetting, four claws, screw mandrel, described briquetting is positioned at the center of described disk body one end surfaces, described disk body one end is equipped with four claws, it is characterized in that: described screw mandrel is the reinforcement screw mandrel, described four claws connect corresponding reinforcement screw mandrel respectively, and described reinforcement screw mandrel is supported on described disk body.
It is further characterized in that: described reinforcement screw mandrel is loaded in the blind hole, described blind hole is distributed in the periphery of described disk body, described reinforcement screw mandrel spindle end is connected with described disk body flat thread, described reinforcement screw mandrel outer end is supported on the leading screw mounting blocks, described leading screw mounting blocks is loaded in the screw mandrel mounting groove, described screw mandrel mounting groove is distributed in the periphery of described disk body, the screw mandrel mounting groove of described correspondence is positioned on the same axis of described disk body with described corresponding blind hole, described claw comprises the top pawl, long basic pawl, described top pawl is fastenedly connected the basic pawl of described length, and the basic pawl of described length is connected with reinforcement leading screw screw-threaded engagement.
In the said structure of the present invention, because described reinforcement leading screw is supported on described disk body, the outer-hexagonal axle of described reinforcement leading screw screws up with a wrench earlier during use, realize the preliminary clamping of workpiece, tighten the screw rod of reinforcement leading screw again, its clamping force is improved, and can realize the choose reasonable of workpiece clamping force under the different operating requirement.

Fig. 2 is the vertical view of front view of the present invention;
Fig. 3 is the structural representation (the two ends threaded portion does not mark) of described reinforcement screw mandrel;
Fig. 4 is shown in Figure 1 12 partial enlarged drawing.
(5) specific embodiment
See Fig. 1, Fig. 2, the present invention includes disk body 1, briquetting 2, four claws 3, screw mandrel, briquetting 2 is positioned at the center of disk body 1 upper surface, four claws 3 are installed on the disk body 1, screw mandrel is a reinforcement screw mandrel 4, four claw 3 bottoms connect corresponding reinforcement screw mandrel 4 respectively, and reinforcement screw mandrel 4 is supported on disk body 1.Reinforcement screw mandrel 4 is loaded in the blind hole 5, blind hole 5 is distributed in the periphery of disk body 1, reinforcement screw mandrel 4 spindle ends are connected with disk body 1 flat thread, reinforcement screw mandrel 4 outer ends are supported on leading screw mounting blocks 6, leading screw mounting blocks 6 is loaded in the screw mandrel mounting groove 7, screw mandrel mounting groove 7 is distributed in the periphery of disk body 1, corresponding screw mandrel mounting groove 7 is positioned on the same axis of disk body 1 with corresponding blind hole 5, claw 3 comprises top pawl 8, long basic pawl 9, top pawl 8 is fastenedly connected long basic pawl 9, and long basic pawl 9 bottoms are connected with reinforcement leading screw 4 screw-threaded engagement.
Its operation principle is as follows: spanner is tightened outer-hexagonal axle 10 (see figure 3)s of described reinforcement leading screw 4, it drives reinforcement screw mandrel 4 to central motion, and then drive long basic pawl 9 to central motion, thereby the top pawl is to central motion, realize the preliminary clamping of workpiece, tighten screw rod 11 (see figure 3)s of reinforcement leading screw 4 again, its clamping force is improved, and can realize the choose reasonable of workpiece clamping force under the different operating requirement.
