Detailed Description

The jigger clamp provided by the embodiment is used for radially clamping a motor shaft, and comprises two clamp bodies 1 of the same type, referring to fig. 1 to 3.

The specific structure of the clamp body 1 comprises a jaw section 100, a clamp handle section 200 and a connecting part 300 positioned between the jaw section 100 and the clamp handle section 200, wherein the two clamp bodies 1 are hinged at the connecting part 300 so that the two clamp bodies 1 are in crossed symmetry, and when the clamp handle sections 200 of the two clamp bodies 1 are held to be close to or far from each other, the two jaw sections 100 can be opened and closed.

In addition, in order to stably maintain the open angle of the jaw segments 100 after clamping the motor shaft, a locking member is provided at the hinge of the two jaw bodies 1 for locking the relative positions of the two jaw bodies 1.

The opposite inward side of the jaw section 100 is provided with a first cambered surface 3 which is in an elliptical arc shape, the first cambered surface 3 is used as a clamping surface of a motor shaft, the outer side of the jaw section 100 is provided with a second cambered surface 4 which is in a semicircular shape, and the first cambered surface 3 and the second cambered surface 4 are concentrically arranged.

Because the contact area between the first cambered surface 3 and the motor shaft is very small when the jaw section 100 clamps the motor shaft, in order to further prevent slipping, the jaw section 100 is provided with the abutting piece 2, and the abutting piece 2 can radially abut against the motor shaft along the motor shaft when the jaw section 100 clamps the motor shaft.

The specific structure of the abutting part 2 comprises a shaft seat 21 and an abutting shaft 22, wherein the shaft seat 21 is arranged on the second cambered surface 4 in a sliding manner, the abutting shaft 22 is radially arranged along the second cambered surface 4, the abutting shaft 22 is provided with external threads and is in fit and screwed connection with the shaft seat 21, and correspondingly, the shaft seat 21 is vertically provided with a threaded hole which can be in threaded fit with the abutting shaft 22.

For the convenience of the movement of the abutting shaft 22, the jaw section 100 is further provided with a vertically-opened through groove 5, the through groove 5 penetrates through the first cambered surface 3 and the second cambered surface 4, the abutting shaft 22 is arranged in the through groove 5, one end of the abutting shaft penetrates out of the first cambered surface 3 and is connected with a buffer rubber cushion 6, and the buffer rubber cushion 6 has the function of preventing the end part of the abutting shaft 22 from slipping on a motor shaft.

More specifically, the second cambered surface 4 is provided with a guide groove 7, the shaft seat 21 is slidably assembled in the guide groove 7, and the guide groove 7 and the second cambered surface 4 have the same radian, so that the shaft seat 21 can slide along the second cambered surface 4, and no matter which position is slid, the abutting shaft 22 is along the radial direction of the motor shaft.

In addition, the rubber pad 8 is symmetrically arranged on the first cambered surface 3 about the through groove 5, and the rubber pad 8 is provided with an anti-slip tooth surface on one side attached to the motor shaft for further preventing slipping.

In this embodiment, the jaw section 100 bites the motor shaft by pulling the jaw handle section 200, then, the shaft seat 21 is slid to a proper position, and the length of the abutting shaft 22 is adjusted in a spiral manner, so that the end with the buffer rubber pad 6 abuts against the motor shaft, thereby further fixing the motor shaft and avoiding slipping during the driving.
