Abstract
The utility model relates to a three-jaw chuck with various clamping ways. The three jaw chuck structurally comprises a round chuck engine body, three clamping jaws and a rotary connector, wherein the rotary connector is formed in one side of the chuck engine body, and the three clamping jaws are arranged by taking the center of a circle of the chuck engine body as a center in a triangular way; a driving mechanism is arranged in the chuck engine body, the three clamping jaws are respectively connected with the rotary connector through the driving mechanism, the positions on the surface of the center of the circle of the chuck engine body corresponding to the three clamping jaws are provided with sliding rails, and the clamping jaws are movably connected with the sliding rails and are further provided with suction devices and electromagnets. According to the three-jaw chuck, a clamping device can be clamped by clamping the outer wall of the clamping device, and the device can be clamped through magnetic force and suction, so that the three-jaw chuck can be convenient and practical to use; furthermore, a strip-shaped article can be clamped, so that the application range of the jaw chuck can be increased.
Description
Technical field
The utility model relates to the fixture to device in a kind of machining, particularly a kind of scroll chuck with multiple clamping mode.
Background technology
Along with the increasing device of industrial expansion need to be used claw chuck and clamps, but after clamping, some high accuracy devices use generic card dog chuck is easy to cause damage, affect precision, just seem particularly important so design a kind of scroll chuck with multiple clamping mode.
Chinese invention patent discloses a kind of scroll chuck No. CN102653005A, its structure comprises disk body of chuck and claw, described claw is arranged on disk body of chuck, on described claw, be also provided with compacting part, described compacting part comprises pressing plate, adjusts bolt and hold-down bolt, and described pressing plate is connected by hold-down bolt and adjustment bolt with claw.This invention clamps device by bolt, but adopting said method is easy to cause the damage of high accuracy device when high accuracy device is clamped, and it can not meet modern production demand.
Summary of the invention
The utility model technical issues that need to address are by magnetic force and suction, high accuracy device to be clamped, and prevent that high accuracy device is damaged; A kind of scroll chuck with multiple clamping mode is provided.
For solving above-mentioned technical problem, structure of the present utility model comprises circular chuck body, three claws and rotatable interface, and rotatable interface is arranged on the side of chuck body, and three claws are equilateral triangle and arrange centered by the center of circle of chuck body; In chuck body, be provided with driving mechanism, three claws are connected with rotatable interface by driving mechanism respectively, the position corresponding with three claws, the center of circle surface of chuck body is respectively equipped with slide rail, and claw is movably connected on slide rail, is also provided with suction device and electromagnet on claw.
Further: described claw is to be connected to form successively by slide block, electromagnet and chuck, and suction device is arranged on the upper surface of slide block.
Further again: described suction device is air pump, on slide block, have suction hole, air pump is arranged in suction hole.
Further again: described driving mechanism is to be connected to form successively by pinion, gear wheel and tooth bar, and pinion is connected with rotatable interface, the back side of three claws is connected with respectively a tooth bar.
Further again: the circle centre position of described chuck body has through hole.
Adopt after said structure, the utility model not only can clamp it by the outer wall of gripping element, and can clamp by magnetic force and suction very convenient practicality to device; And the design can also clamp strip object, increase the range of application of claw chuck; Outside this utility model also have advantages of simple in structure, be easy to manufacture, practicality and high efficiency, good looking appearance.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure: 1 is chuck body, 2 is through hole, and 3 is rotatable interface, and 4 is chuck, and 5 is slide rail, and 6 is electromagnet, and 7 is slide block, and 8 is suction hole
The specific embodiment
A kind of scroll chuck with multiple clamping mode as shown in Figure 1, structure comprises circular chuck body 1, three claws and rotatable interfaces 3, rotatable interface 3 is arranged on the side of chuck body 1, and three claws are equilateral triangle and arrange centered by the center of circle of chuck body 1; It is characterized in that: in chuck body 1, be provided with driving mechanism, three claws are connected with rotatable interface 3 by driving mechanism respectively, the position corresponding with three claws, the center of circle surface of chuck body 1 is respectively equipped with slide rail 5, claw is movably connected on slide rail 5, is also provided with suction device and electromagnet 6 on claw.Described claw is to be connected to form successively by slide block 7, electromagnet 6 and chuck 4, and suction device is arranged on the upper surface of slide block 7; Described suction device is air pump, has suction hole 8 on slide block 7, and air pump is arranged in suction hole 8.In the time that the device of clamping is general device, the rotatable interface 3 that the utility model is arranged on chuck body 1 side by rotation makes three claws move towards chuck hub along slide rail 5, thereby utilizes chuck 4 to clamp object.When clamp be high-precision metal device time, by controller, to electromagnet 6, charging is magnetic its band, rotates rotatable interface 3 and makes three electromagnet 6 can just in time adsorb metal, thereby complete the clamping to device; When clamping be the nonmetal device of high accuracy time, rotate equally rotatable interface 3 and make the suction hole 8 on slide block 7 face device, start the air pump that is positioned at suction hole 8 by controller, thereby realize the clamp operation to device by air pressure.The utility model not only can clamp material by the common mode that clamps, and can realize the clamping to the valuable device of high progress, very highly effective by magnetic force and pressure.
Driving mechanism is as shown in Figure 1 to be connected to form successively by pinion, gear wheel and tooth bar, and pinion is connected with rotatable interface 3, and the back side of three claws is connected with respectively a tooth bar.The utility model, by rotating rotatable interface 3, makes pinion rotate with gear wheel, thereby slide block 7 is moved to chuck hub along slide rail 5 under the drive of tooth bar, thereby complete the clamping to device.The utlity model has simple in structure, be easy to manufacture, advantage with low cost.
The circle centre position of chuck body 1 as shown in Figure 1 has through hole 2.Sometimes need the device clamping while being strip device, one end of device can be stretched in chuck body 1 along through hole 2, thereby be convenient to the clamp operation to material.
Adopt in sum after said structure, the utility model not only can clamp it by the outer wall of gripping element, and can clamp by magnetic force and suction very convenient practicality to device; And the design can also clamp strip object, increase the range of application of claw chuck; Outside this utility model also have advantages of simple in structure, be easy to manufacture, practicality and high efficiency, good looking appearance.
