Description

A Pneumatic Vertical Fixture for Cover Plates

technical field

The utility model relates to the technical field of pneumatic clamps, in particular to a pneumatic vertical clamp for cover plates.

Background technique

The clamping and positioning of the cover plate workpiece in the original machining center is positioned through the blank surface, and the two sides are manually clamped. The worker needs to hold the cover plate to ensure the positioning is in place, and then manually tighten the clamping structure to clamp the cover plate workpiece. Then the screw drives the pressure plate to compress the workpiece. The operation speed is slow, the production efficiency is low, and the clamping force is unstable. Because the workpiece is thin and the positioning area is small, the positioning surface of the workpiece that is prone to cover plate is clamped during the clamping process. There are problems such as loose sticking and unstable product processing dimensions, and the product yield is low.

A pneumatic vertical clamping fixture for a cover plate, which includes a frame on which a horizontal positioning clamping mechanism and a vertical positioning clamping mechanism are installed, wherein the horizontal positioning clamping mechanism includes a first L-shaped plate, the horizontal positioning frame surrounded by the second L-shaped plate, the first L-shaped plate and the second L-shaped plate are located above the outer periphery of the backing plate, and the first L-shaped plate is fixedly installed on the backing plate, so The right angle of the second L-shaped plate is installed on the frame through a pivot pin, and an adjusting screw is arranged on a side plate of the second L-shaped plate; the vertical positioning clamping mechanism includes a baffle plate and a pressing plate, and the The baffle is installed on the frame, the baffle is located on one side of the pressure plate, the pressure plate is located above the backing plate, the pressure plate is movably installed on the connecting piece through a pin, and the connecting piece is installed on cylinder piston rod.

It is further characterized in that: the frame includes an upper base plate, a lower base plate, and a column, the baffle plate and the backing plate are installed on the upper base plate, and the right angle of the second L-shaped plate is installed on the upper base plate through a pivot pin. The upper base plate is provided with a relief hole, the cylinder is installed on the lower base plate, and the connecting piece is installed after the piston rod of the cylinder passes through the relief hole.

The horizontal positioning clamping mechanism and the vertical positioning clamping mechanism are in a 2:1 configuration, each of the vertical positioning clamping mechanisms is arranged above the middle of the two horizontal positioning clamping mechanisms, and the column pin and The pressure plate is interference fit, and the pin is clearance fit with the connecting piece.

The device of the utility model is applied to the clamping and positioning of the workpiece. When the screw is tightened to compress the workpiece, the second L-shaped plate is driven to move, and the other side of the workpiece is pressed to achieve the effect of double clamping with one movement. The cylinder The piston rod is driven to drive the pressure plate to move up and down to compress the workpiece, which ensures the consistency of the pressing force and the close contact of the positioning surface of the workpiece during the clamping process, which improves the stability of the processing size and the high yield of the product; The horizontal positioning and clamping mechanism and the vertical positioning and clamping mechanism are arranged in a 2:1 configuration, so that the cylinder drives the piston rod to drive the pressure plate to simultaneously compress the workpieces on both sides, which further improves the work efficiency.
