Description

TECHNICAL FIELD

[0001] The utility model relates to mechanical tool clamping rotation field, concretely to a high accuracy clamping rotation structure. BACKGROUND

[0002] At present, the clamping rotation of workpiece is all adopted to install the claw on the index head, clamps through the adjustment claw, and rotates positioning through the index head. Since the chuck is more suitable for the circular workpiece when clamping, it cannot meet the clamping requirement of the square workpiece with high surface precision requirement. Therefore, a tool structure which can meet the clamping of square workpiece and realize high-precision rotation needs to be designed. SUMMARY

[0003] The utility model solves above-mentioned problem adopts technical scheme: a high accuracy clamping rotation structure is by base, fixed base, upper slide, clamping servo motor, ball screw, guide, rotation servo motor, rotation driving shaft, workpiece, rotation driven shaft is composed, its characterized in being: base is horizontally placed, and the upper portion of base is equipped with fixed base and upper slide, and fixed base and upper slide are installed on base through guide, and fixed base is fixed together with base and is not movable, and clamping servo motor and ball screw are installed on upper slide, and clamping servo motor rotation can control ball screw transmission, and drive upper slide whole to do up-down reciprocating motion. Rotation servo motor is installed on the right side of upper slide, and the lower end of rotation servo motor is installed with rotation driving shaft, and rotation driven shaft is installed on the right side of fixed base, and the center of rotation driven shaft and rotation driving shaft is on the same vertical line, and the workpiece is placed in the gap between rotation driving shaft and rotation driven shaft.

[0004] The utility model adopts high-precision clamping rotation structure, which not only ensures the clamping ability of the clamp, but also realizes the arbitrary rotation positioning of the workpiece 360°, greatly improving the automatic clamping ability of the machine tool.

[0008] The utility model will be further described in combination with the drawings:

[0009] AsFigure 1 、 Figure 2 The utility model relates to a high accuracy clamping rotation structure, by base 1, fixed seat 2, upper slide 3, clamping servo motor 4, ball screw 5, guide rail 6, rotation servo motor 7, rotation driving shaft 8, work piece 9, rotation driven shaft 10 are formed, its characterized in that: base 1 is horizontal and is placed, and the upper portion of base 1 is equipped with fixed seat 2 and upper slide 3, and fixed seat 2 and upper slide 3 are installed on base 1 through guide rail 6, and fixed seat 2 is fixed together with base 1 and is not movable, and clamping servo motor 4 and ball screw 5 are installed on upper slide 3, and clamping servo motor 4 rotation can control ball screw 5 transmission, and drive upper slide 3 whole to make reciprocating motion up and down, rotation servo motor 7 is installed on the right side of upper slide 3, and the lower end of rotation servo motor 7 is installed with rotation driving shaft 8, and rotation driven shaft 10 is installed on the right side of fixed seat 2, and the center of rotation driven shaft 10 and rotation driving shaft 8 is on the same vertical line, and work piece 9 is placed in the gap between rotation driving shaft 8 and rotation driven shaft 10.

[0010] The utility model in using, first work piece 9 is placed on the rotation driven shaft 10 of fixed seat 2 right end, then starts clamping servo motor 4, and clamping servo motor 4 drives ball screw 5 to rotate, makes upper slide 3 slowly downward motion, when upper slide 3 right side rotation driving shaft 8 contacts work piece 9, clamping servo motor 4 stops rotating, and completes the clamping action of work piece 9. Again start rotation servo motor 7, and rotation servo motor 7 drives rotation driving shaft 8 to rotate, and work piece 9 is clamped under rotation driving shaft 8 and rotation driven shaft 10 and follows rotation, can realize the high accuracy rotation of arbitrary angle. When needing to loosen work piece 9, first rotation servo motor 7 returns to the original position, and work piece 9 is clamped under rotation driving shaft 8 and rotation driven shaft 10 and rotates to the original angle, and then starts clamping servo motor 4, and clamping servo motor 4 drives ball screw 5 to rotate, makes upper slide 3 slowly upward motion and returns to the initial position, and completes the loosening process of work piece 9.

[0011] The utility model because adopts above -mentioned structure, adopts high accuracy clamping rotation structure, solved the high accuracy clamping of square work piece and rotation, made the automatic clamping ability of machine tool greatly promoted.
