Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings.
In fig. 1 and 2, the device comprises a fixed seat 1, a pressing cylinder 2, a pressing plate 3, a cover plate 4, a pressing head 5, a boss 5-1, a limit pin 6, a gasket 7, a joint bearing 8, a workpiece 9 and the like.
As shown in fig. 1 and 2, the utility model relates to a plane self-adaptation hold-down mechanism, including fixing base 1, a side-mounting hold-down cylinder 2 in fixing base 1 upper portion.
A piston rod of the pressing cylinder 2 is fixedly connected with a pressing plate 3, a pressing end of the pressing plate 3 is provided with a joint bearing 8, and an inner ring hole of the joint bearing 8 is connected with a pressing head 5.
A limiting component is arranged between the pressure plate 3 and the pressure head 5 to limit the swing amplitude of the pressure head 5.
The pressing end of the pressing plate 3 is provided with a step hole, and the joint bearing 8 is arranged in the step hole.
The pressure head 5 is provided with a boss 5-1 extending axially, the boss 5-1 extends into an inner ring hole of the joint bearing 8, a gasket 7 is arranged at the upper end of the inner ring hole of the joint bearing 8, and a connecting screw penetrates through a through hole of the gasket 7 to be fixedly connected with the pressure head 5.
The limiting part adopts a limiting pin 6, the upper end of the limiting pin 6 is fixedly connected with the pressing plate 3, and the lower part of the limiting pin 6 extends into the positioning hole of the pressing head 5.
In order to realize reliable compression of the workpiece, the bottom of the pressure head 5 is provided with an arc-shaped groove matched with the shape of the workpiece 9 so as to reliably compress the workpiece 9.
