Detailed Description
The technical solution of the present patent will be described in further detail with reference to the following embodiments.
Example 1
Referring to the attached drawings in the specification, in the embodiment of the utility model, the hook-type three-jaw clamping device comprises a jaw disc 1 and jaws 2, wherein a power source 3 is arranged at the top end of the jaw disc 1, three jaw mounting grooves 4 are formed in the jaw disc 1, and the jaws 2 are arranged on the jaw mounting grooves 4.
Further, the jaw 2 is an external clamping jaw.
Furthermore, the bottom end of the inner side of the outer clamping claw is provided with a boss I5
Further, the power source 3 is one of electric power and pneumatic power.
Furthermore, a rubber protection pad 7 is arranged at the position where the top end of the boss I5 is combined with the side wall of the bottom end of the clamping jaw 2.
Example 2
Further, the jaw 2 is an inner supporting jaw.
Further, the bottom end of the outer side of the inner supporting clamping jaw is provided with a second boss 6.
Further, the power source 3 is one of electric power and pneumatic power.
Furthermore, a rubber protection pad 7 is arranged at the position where the top end of the second boss 6 is combined with the side wall of the bottom end of the clamping jaw 2.
The working principle is as follows: the clamping reliability of the clamping device is mainly embodied in that a boss I5 or a boss II 6 is added at the bottom end of a clamping jaw 2, so that the clamping device has a limiting effect on the axial direction of a workpiece and prevents the workpiece 8 from sliding off along the axial direction; the cost of the device is mainly embodied in the power source of the three-jaw clamping device, no matter the power source 3 is pneumatic or electric, when the first boss 5 or the second boss 6 is added at the bottom end of the clamping jaw 2, the selection of the power source 3 can reduce parameters, so that the cost of purchasing the power source and the cost of later-stage production operation are reduced
According to the utility model, the boss I5 or the boss II 6 is additionally arranged at the bottom end of the clamping jaw 2, when a workpiece 8 is clamped, the workpiece 8 is clamped by the generated friction force except after the surfaces of the brake drums are clamped by the three clamping jaws 2, and the boss I5 or the boss II 6 has a limiting effect on the axial direction of the brake drums, so that the workpiece 8 is prevented from sliding off along the axial direction, and the clamping tightness is improved; through being provided with the rubber protective sheath, the effectual centre gripping work of having avoided carrying on for a long time, produces the friction between boss and the work piece 8, reduces the life of jack catch 2.
