Description

Locking device

The locking device of the invention provides a device for eliminating the bias resistance between the locking components and improving the pressure application efficiency when the workpiece is locked and clamped.

In the case of locking the workpiece, such as the fitter or the clamping tool of the machine holder that needs to be pinched, the locking device must be used as the workpiece clamping basis, as shown in Figures 1 and 2, The locking device 10 normally has a combined base 40 to form a clamp of the fitter, and the two correspond to an clamping space 12. The locking device 10 is driven by a driving screw 50 through the fixed force bearing pier 20 to move the movable pillow 30 Displacement to change the space of the clamping space 12 and clamping pressure occurs, and the driving screw 50 is commonly used as a manual or automated electromechanical device (not shown) by external power input.

Referring to FIG. 2 and FIG. 3, the clamping space 12 holds the workpiece 90. The locking device 10 is provided with a rotating force screw hole 21 provided by the fixed force bearing pier 20 according to the working axis S, and the screw is driven by the rotary cutting action. 50 to generate a pressing force amount converted by the high sliding rate along the working axis S, and to the clamping space 12, since the height of the workpiece 90 is not necessarily, the position pointed by the working axis S does not necessarily pass through the workpiece 90. At the center point, a gap angle of the active fit between the drive screw 50 and the movable presser 30 is generated to generate a biasing resistance, as shown in FIG.

The force-resistant pier body 20 provides a driving propeller 50 to generate a torsional propulsion force, and the movable pressure pillow 30 is moved to the right when clamping.

In conjunction, when the clamping action is retracted, the driving screw 50 can act on the buckle 86 through the cutting groove 58 to drive the movable pressure pillow 30 to be displaced.

As described above, when the workpiece is offset from the working axis S (please match the drawing in FIG. 2), the biasing working axis S causes the movable pressing pillow 30 to generate a vertical torque change due to the offset of the center point of the workpiece 90. The active engagement between the outer circular table of the working end 51 and the interlocking culvert 33 forms an eccentricity. Although the force of the working end 51 is transmitted through the interlocking spherical body 59 toward the concave-shaped stop surface 34, the working end 51 itself Having a length, offsetting the working axis S via the applied point of force, causing the displacement direction of the movable pressure pillow 30 to be angulated, causing the working end 51 and the interlocking culvert 33 to generate deflection friction, or the interlocking sphere 59 pushing toward the squatting surface 34. Since the interlocking ball 59 is rotated by the working end 51, the friction between the generated torque and the stopping surface 34 is also caused by the aforementioned clamping force to shift the working axis S, so that the friction on the inner surface of the stopping surface 34 is generated.

Even if the interlocking culvert 33 provided in the movable pressure pillow 30 is only inserted into the interlocking ball 59, the length of the working end 51 is eliminated. However, if the working axis S is offset, the thrust of the interlocking ball 59 against the damming surface 34 is the same. It will cause the vertical yaw angle during the displacement of the movable pillow 30.
