Abstract
The utility model relates to a floating automatic guide and downward pressing device, which comprises an upper die support plate, an upper die fixing frame, a lower die support plate and a bottom plate from top to bottom in sequence; the upper die support plate is connected with the upper die fixing frame in an embedded manner through a universal ball, and a universal ball pressing plate is further arranged on the upper die support plate; the upper die fixing frame is connected with the pull-down cylinder through a cylinder lengthening column, and the pull-down cylinder is fixed on the bottom plate through screws. The utility model discloses only need to dial away universal ball clamp plate about to, just can take out and go up the mould support plate and maintain or change, the simple easily adjustment of action, the butt joint is accurate, does not harm the customer mainboard. When the product is updated, only the lower die carrier plate needle plate and the upper die carrier plate part need to be replaced, the frame and the pull-down structure can be repeatedly utilized, the compatibility is high, the cost is saved, and the reliability is high.
Description
Technical Field
The utility model relates to a PCB test fixture, more specifically say, relate to an automatic device of just pushing down of leading floats.
Background
The test fixture belongs to a category under the fixture, and is specially used for testing and experimenting functions, power calibration, service life, performance and the like of a product. The structure that now commonly used is that directly will go up the mould structure and be connected with cylinder or quick clamp, pushes up the mould through quick clamp or cylinder effort and pushes down and the lower mould butt joint, and this kind of structure is because last mould position relatively fixed, and it is inaccurate to lead to the fact mould and lower mould to counterpoint to do not float around, about, go up the mould and push down unstably easily, crushes customer's PCB board, damages connector on the board, and the needle is pricked inaccurately, is maintained inconvenient scheduling problem.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model lies in that, to prior art's defect, a device that floats and leads directly to push down automatically is provided.
The utility model provides a technical scheme that its technical problem adopted is: the device is characterized in that a universal ball is pressed into an upper die carrier plate, the upper die carrier plate is arranged in an upper die fixing frame and supported by a spring, the universal ball pressing plate is pressed on the spherical surface of the universal ball through the front-back left-right floating distance of the fixing frame, and the lower surface of the upper die carrier plate is supported by the spring, so that the contact surface between the upper surface universal ball pressing plate and the upper die carrier plate is only one spherical surface, the contact areas of the upper surface and the lower surface are small, and the friction force is small when the upper die carrier plate moves left and right in the fixing frame. After the chamfer on the upper die guide post is sleeved with the oil-free liner on the lower die carrier plate when the cylinder is pulled down, the position of the upper die can be easily and automatically guided, so that the probe of the upper die and the connector can be accurately butted with a detected plate.
Implement the utility model discloses an automatic device of just pushing down of leading floats has following beneficial effect: the utility model discloses only need to dial away universal ball clamp plate about to, just can take out and go up the mould support plate and maintain or change, the simple easily adjustment of action, the butt joint is accurate, does not harm the customer mainboard. When the product is updated, only the lower die carrier plate needle plate and the upper die carrier plate part need to be replaced, the frame and the pull-down structure can be repeatedly utilized, the compatibility is high, the cost is saved, and the reliability is high.
