The cylinder drives the fixing plate to move, the clamping plate drives the clamping ring to move downwards, the clamping ring is in contact with the lower inclined surface, and the clamping claw arm is driven to rotate inwards by extrusion of the lower inclined surface to clamp the bolt; when the bolt needs to be loosened, the clamping plate drives the clamping ring to move upwards, the clamping ring is in contact with the upper inclined surface, the clamping claw arms are driven to rotate outwards by means of extrusion of the upper inclined surface, and clamping on the bolt is loosened.

Wherein the clamping ring has an annular groove into which the ends of the clamping plate are inserted. So as to drive the clamping ring to move.

The connecting portion is fixedly provided with a fixing pin, and the clamping claw arm is connected with the fixing pin in a rotating mode. The installation of the gripper arms is convenient.

Wherein, the lower part of the clamping claw arm is bent inwards and extends to form the clamping end. The bolt is convenient to clamp.

To sum up, this clamping jaw for bolt spraying has simple structure, and stability is high, convenient to use, the quick advantage of centre gripping.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the orientation words such as "upper, lower" and "top, bottom" etc. are usually based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, and in the case of not making a contrary explanation, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore, should not be interpreted as limiting the scope of the present invention; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.

As shown in fig. 1-8, a clamping jaw is used in bolt spraying, including fixed plate 1, fixed plate below fixed mounting has two clamping jaw seats 2, and two clamping jaw seat intervals set up, the clamping jaw seat has the connecting portion that three outside protrusion set up, connecting portion follow clamping jaw seat circumference equipartition sets up, the spread groove has been seted up on the connecting portion, it has clamping jaw arm 3 to articulate in the spread groove, the lower extreme of clamping jaw arm is exposed to the hands 12, install on the fixed plate and be used for driving the rotatory drive assembly of clamping jaw arm.

The driving assembly comprises a cylinder 4 fixedly mounted on a fixing plate, a cylinder body of the cylinder is fixedly connected with the fixing plate through a bolt, and a piston rod of the cylinder penetrates through the fixing plate and is fixedly connected with a clamping plate 5; the clamp ring seat is sleeved with a clamp ring 6, the outer side of the clamp claw arm is provided with an upper inclined surface 7 and a lower inclined surface 8, the clamp ring is located between the upper inclined surface and the lower inclined surface, and the clamp plate is connected with the clamp ring and used for driving the clamp ring to move.
