Detailed Description

The present invention will be further described with reference to the following detailed description of preferred embodiments thereof, which is to be read in connection with the accompanying drawings.

First, the centering, positioning and clamping device according to the embodiment of the present invention will be described with reference to fig. 1 to 3, which is used for positioning and clamping blank workpieces and has a wide application range.

As shown in FIGS. 1-3, the utility model discloses centering positioning and clamping device of embodiment has base 1, positioning seat 2, power module 4 and clamping module.

Specifically, as shown in fig. 1 to 3, the positioning seat 2 is fixedly disposed on one side of the base 1, and the power module 4 is disposed on the other side of the base 1, in this embodiment, the power module 4 is a hydraulic linear cylinder.

Furthermore, a positioning cavity 21 is arranged in the positioning seat 2, a blank workpiece is put in from one end of the positioning cavity 21, a clamping module is arranged in the positioning cavity 21, and the clamping module can reciprocate in the positioning cavity 21.

Further, the positioning cavity 21 is Y-shaped, the positioning cavity 21 includes a pair of inclined surfaces 211 and a linear cavity 212, the pair of inclined surfaces 211 are disposed oppositely, the pair of inclined surfaces 211 are disposed on the upper portion of the positioning cavity 21, and the bottom of the inclined surfaces 211 is connected to the linear cavity 212.

Specifically, as shown in fig. 1 to 3, the clamping module is disposed in the positioning seat 2, the clamping module is connected to the power module 4, and the power module 4 drives the clamping module to reciprocate in the positioning seat 2.

Further, the clamping module has: one end of the spring clamp 31 is connected with the power module 4, the other end of the spring clamp 31 is provided with a pair of expanded spring chucks 311, and the pair of spring chucks 311 are used for clamping blank workpieces.

Further, the contact surface of the collet chuck 311 holding the blank workpiece is a tooth surface 3111.

Further, the angle of opening of the pair of collet chucks 311 matches the inclination angle of the pair of inclined surfaces 211, ensuring smooth operation.

Further, the utility model discloses centering positioning and clamping device of embodiment still has: and the hinge push-pull block 5 is arranged in the base 1, two ends of the hinge push-pull block are respectively connected with the spring clamp 31 and the hydraulic linear cylinder, and the hydraulic linear cylinder drives the spring clamp 31 to reciprocate in the positioning cavity 21 through the hinge push-pull block 5.
