The thickness of the clamp is smaller than the height of the tube base (the sum of the thicknesses of the pins and the tube base), so that when the clamp is placed on a planar object, the tube base is jacked up, and the tube base is convenient to take down from the clamp easily.

The total thickness of the clamp and the thickness of the clamp supporting step 11 is larger than the height of the tube base (the sum of the thickness of the pin and the thickness of the tube base), so that the pin of the tube base is overhead, the tube base can be stably placed on the clamp, and meanwhile, the pin of the tube base is protected.

The anchor clamps are put in the base, and base limit wall 12 is used for mounting fixture, and anchor clamps corner cut 7 and base limit wall U type mouth 13 are convenient for getting of anchor clamps and are put, and anchor clamps support step 11 is used for supporting anchor clamps, and base fretwork framework 14 is used for holding the part that the base pin surpasss anchor clamps thickness, is convenient for fix the base of various pin length, is used for fixing the anchor clamps subassembly on full-automatic chip mounter simultaneously.

The clamp or the clamp base is made of metal.

Compared with the prior art, the beneficial effects of the utility model are that:

the pipe base positioning fixture is simple in manufacturing process and accurate in positioning, a plurality of pipe bases can be effectively fixed, the fixture supporting step 11 of the hollow base is used for supporting the fixture and heightening the pipe base pins, and therefore the pipe bases are stably fixed on the fixture. The corner cut design has been made at four angles of anchor clamps to and base wall 12 all around is opened has U type mouth 13, makes things convenient for anchor clamps to pick up from the base, avoids anchor clamps card on the base. The base hollow frame 14 can fuse the clamp assembly on a feeding table of the full-automatic chip mounter, so that the position deviation of the tube base is prevented from being generated along with the shaking or vibration of the full-automatic chip mounter; when the device is placed on a discharging table of a full-automatic chip mounter, the device can jack up a pipe base and quickly clamp the pipe base; when the clamp is placed on other plane objects, such as a table top, the pipe base is jacked up due to the height difference, and the pipe base is convenient to clamp. The production efficiency can be improved while the product quality is greatly improved, and the method can be used for various products of the same type and different models. The assembling positioning fixture suitable for other devices can be manufactured according to the sizes and the shapes of different tube bases.

In addition, according to the shape and the size of the pipe base, the utility model provides a basic structure model of a pipe base positioning clamp assembly, in the concrete implementation process, can carry out reasonable deformation to each part according to the concrete shape and the size of each part, all belong to the protection scope of the invention.
