Detailed Description

The following further describes embodiments of the present invention with reference to examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1, an automatic positioning frame includes a workpiece platform 1 for supporting a workpiece, an abutting plate 2 vertically and fixedly disposed on one side of the workpiece platform 1, and a clamping mechanism disposed on the workpiece platform 1 for clamping the workpiece between the workpiece platform 1 and the abutting plate 2;

the clamping mechanism comprises a swing rod 3, a first clamping arm 4, a first clamping head 5, a sliding part 6, a second clamping arm 9, a second clamping head 10 and a driving rod 7, wherein the lower end part of the swing rod 3 is rotatably arranged on the workpiece platform 1, the first clamping arm 4 is fixedly arranged on the swing rod 3, the first clamping head 5 is fixedly arranged on the first clamping arm 4, the sliding part 6 is arranged on the swing rod 3 in a sliding mode along the length direction of the swing rod 3, the middle part of the second clamping arm 9 is rotatably arranged at the upper end part of the swing rod 3, the second clamping head 10 is fixedly arranged at one end of the second clamping arm 9, one end part of the driving rod 7 is rotatably connected with the other end part of the second clamping arm 9, the other end part of the driving rod 7 is rotatably connected with the sliding part 6, an elastic part 11 is arranged between the sliding part, the first clamping arm 4 is located between the abutting plate 2 and the swing rod 3, the first clamping head 5 is over against the abutting plate 2, the second clamping head 10 is over against the workpiece platform 1, and a clamping surface of the first clamping head 5 is perpendicular to a clamping surface of the second clamping head 10.

In the preferred embodiment of the present invention, the driving mechanism is a driving cylinder 8, a cylinder body of the driving cylinder 8 is rotatably connected to the workpiece platform 1, and a piston rod of the driving cylinder 8 is rotatably connected to the sliding member 6.

In the preferred embodiment of the present invention, the sliding element 6 is a sliding sleeve slidably sleeved on the swing rod 3, in addition, a sliding groove may be formed in the swing rod 3 along the length direction thereof, and the sliding element 6 is provided with a protruding portion matched with the sliding groove, for example, the sliding groove is a dovetail groove, and the protruding portion is a dovetail slider.

In the preferred embodiment of the present invention, the elastic member 11 is a spring sleeved on the swing rod 3, but is not limited to a spring, and any elastic member can be used, such as a gas spring.

For convenience of processing, the abutting plate 2 and the workpiece platform 1 are integrally formed, that is, the workpiece platform 1 is L-shaped, and the abutting plate 2 is a part of the L-shaped.
