Abstract
The utility model relates to a quick-changing clamp device, in particular to the quick-changing clamp device which can eliminate repeated positioning errors. A clamp fixing plate is fixed on a machine tool operating platform through a bolt, wedge-shaped irons are fixed on a cylinder piston rod, the wedge-shaped irons and a cylinder are fixed on a cylinder fixing seat which is fixed on the clamp fixing plate, a cylindrical pin and a diamond-shaped pin are fixed on the clamp fixing plate, two quick-changing clamp bodies are positioned along with the diamond-shaped pin in a matching mode through a positioning sleeve and the cylindrical pin on the quick-changing clamp bodies, and workpieces are respectively fixed on the two quick-changing clamp bodies. The quick-changing clamp device is characterized in that the wedge-shaped irons are driven by the cylinder so that an inclined face of each wedge-shaped iron and an inclined face of each quick-changing clamp body interact to clamp the quick-changing clamp bodies, the quick-changing clamp bodies rotate in the same direction driven by axial component force of the two wedge-shaped irons so that gaps between the cylindrical pin and the positioning sleeve and between the diamond-shaped pin and the positioning sleeve can be eliminated, the quick-changing clamp bodies are always fixed on an only determined position and the positioning errors can be eliminated.
Description
Technical field
The utility model relates to a kind of magic chuck device, particularly can eliminate the magic chuck device of resetting error.
Background technology
At present, common magic chuck or die device are to locate with an end face, a straight pin and a rhombus pin, and the mode that compresses from above again fixes.But, since gapped between straight pin and rhombus pin and the positioning sleeve, there is position error.
Summary of the invention
Have the deficiency of position error in order to overcome existing magic chuck or die device, the utility model provides a kind of magic chuck or die device, can make magic chuck or mould eliminate position error.The technical scheme that its technical problem that solves the utility model adopts is: clamp fixing plate is fixed by bolts on the platen, drift is fixed on the cylinder piston rod, drift and cylinder are fixed on the cylinder holder, the cylinder holder is fixed on the clamp fixing plate, fix a straight pin and a rhombus pin on the clamp fixing plate, 2 magic chuck bodies are by the positioning sleeve on it and straight pin and rhombus pin matched in clearance location, workpiece is fixed on respectively on 2 magic chuck bodies, it is characterized in that: drive drift by cylinder, inclined-plane and the inclined-plane on the magic chuck body on the drift are interacted, clamp the magic chuck body, two drift axial thrust loads make magic chuck body rotating Vortex, cause the gap between straight pin rhombus pin and positioning sleeve to be eliminated, the position of magic chuck body always is fixed on the well-determined position, reaches the purpose of eliminating position error.The beneficial effects of the utility model are can make the elimination of magic chuck or mould or reduce position error.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.Fig. 1 is the front view of magic chuck.Fig. 2 is the top view of magic chuck.In Fig. 1, Fig. 2,1. cylinder, 2. cylinder piston rod, 3. cylinder holder, 4. drift locking nut, 5. guider screw, 6. drift, 7. drift inclined-plane, 8. magic chuck body inclined-plane, 9. positioning sleeve, 10.2 piece magic chuck body, 11. hands are removed groove, 12. bolts, 13. bolt, 14. straight pins, 15. clamp fixing plate, 16.T the shape piece, 17. anchor clamps symmetrical center line, 18. rhombus pins.
The specific embodiment
At Fig. 1, among Fig. 2, clamp fixing plate (15) is fixed on the platen with bolt (13), drift (6) is fixed on the cylinder piston rod (2), drift (6) and cylinder (1) are fixed on the cylinder holder (3), cylinder holder (3) is fixed on the clamp fixing plate (15), fix a straight pin (14) and a rhombus pin (18) on the clamp fixing plate (15), 2 magic chuck bodies (10) are by the lining (9) on it and straight pin (14) and rhombus pin (18) matched in clearance location, workpiece is fixed on respectively on 2 magic chuck bodies (10), it is characterized in that: drive drift (6) by cylinder (1), inclined-plane (7) and the inclined-plane (8) on the magic chuck body on the drift (6) are interacted, clamp magic chuck body (10), two drifts (6) axial thrust load makes magic chuck body (10) rotating Vortex, cause the gap between straight pin (14) rhombus pin (18) and positioning sleeve (9) to be eliminated, the position of magic chuck body (10) always is fixed on the well-determined position, reaches the purpose of eliminating position error.
