The utility model has large clamping area and is not suitable for clamping circuit boards with complex shapes or numerous components.
Disclosure of Invention
Utility model purpose:
the movable probe card clamp has certain elasticity during loading, and the thickness of a pressed workpiece can be flexibly adjusted.
The technical scheme is as follows:
the movable probe card clamp is provided with a support rod and a pressing component perpendicular to the support rod. One end of the supporting rod is provided with a shaft hole which is horizontally arranged, the middle of the supporting rod is provided with a through hole which is vertically communicated, and the other end of the supporting rod is downwards fixedly connected with a pressing component.
The shaft hole can penetrate through the fixed shaft (clearance fit is convenient for the fixed shaft to rotate), and the supporting rod can drive the pressing rod to rotate around the fixed shaft; the through hole can pass through a screw which can be in threaded connection with a foundation below.
The pressing assembly consists of a cylindrical shell (the lower end of the shell can be provided with an outlet which is contracted inwards, the diameter of the outlet is smaller than that of the cylindrical pressing rod, so that the pressing rod cannot fall off), a spring, and a cylindrical pressing rod (the lower end of a large cylinder of the pressing rod can be provided with a small cylinder with a smaller diameter, and the diameter of the small cylinder is smaller than that of the outlet). The top of the inner part of the shell is connected with the upper end of a spring, the spring can stretch up and down, and the lower end of the spring is connected with the upper end of a pressure lever. When the spring stretches, the small cylinder can move up and down at the outlet, but cannot retract into the shell. When the workpiece is pressed from the lower part, the spring contracts, and the lower end of the small cylindrical pressure lever presses the workpiece.
The diameter of the outlet of the shell and the diameter of the small cylinder form a clearance fit relation with small tolerance, so that certain air tightness is achieved, and meanwhile, no friction resistance exists. When the workpiece is pressed, the workpiece is pressed by the aid of the elastic force of the spring and compressed air in the shell, so that the pressure is high, and the noise is low; when the air pressure inside and outside the shell is the same after the pressing is stable, only the elasticity of the spring presses the workpiece. When the workpiece is released, the spring is gradually released, negative pressure is formed in the air inside the spring instantly, the falling speed of the pressing rod is delayed, the noise is low, the instant elasticity of the spring is limited, and the workpiece and an operator are not easily damaged.
Has the advantages that:
the utility model has reasonable structural design and flexible use, skillfully utilizes compressed air and vacuum, has mild force loading when pressing a workpiece, slowly falls down by the pressure rod when releasing the workpiece, and is safe for operators.
The utility model provides a very little can be done to the anchor clamps size, to big circuit board like the centre gripping of visiting the card, can adopt the combination of many to carry out the centre gripping at the border of difference, is fit for the shape complicacy or the more work piece of components and parts uses.
The pressing workpiece has elasticity and flexibility, and the surface of the workpiece is not easy to damage. The degree of spring compression can have certain range of variation, and the thickness of work piece can be done great regulation.
