The technical effects of the scheme are as follows:
the requirement for high position precision of the workpiece surface is met after the positioning is carried out through the object limiting hole, the requirement for high position precision of a hole to be machined in the workpiece can be met through selection of the positioning hole combination, and after the positioning rod is inserted into the object limiting hole in the positioning plate, the machining precision of the reference hole is judged by judging whether the reference hole can be sleeved on the positioning rod or not. Two positioning units on the positioning plate take two kinds of workpieces into account, and the characteristics that the hole series distribution positions and the distribution circle diameters on the two kinds of workpieces are different can be met. The utility model provides a location frock, it is small, comparatively convenient fastening is few at the edge of normal machine tool workstation, and the area that occupies normal machine tool does not influence normal machine tool and alternates in midway and process other product parts.
Furthermore, the first positioning unit and the second positioning unit are distributed on a concentric outline.
Has the beneficial effects that: the advantage that distributes with one heart lies in, when the locating plate trompil, and it is convenient to the outline line setting-out of the centre of a circle, because distributes with one heart, and is little to locating plate area occupied, has reduced the size of locating plate, has practiced thrift the material of locating plate.
Furthermore, two groups of positioning quadrant parts of the first positioning unit are symmetrically distributed on two sides of a vertical center line of the positioning plate, and two groups of positioning quadrant parts of the second positioning unit are distributed on two sides of a horizontal center line.
Has the advantages that: the positioning quadrant part of the first positioning unit is arranged on the central line, and the rotation angle of the workpiece along the central line can be controlled due to the particularity of the central line, so that the positioning efficiency is improved; and two sets of positioning quadrant parts of the second positioning unit are distributed on two sides of the horizontal center line, so that the positioning holes of the two workpieces are prevented from being punched mutually when holes are formed, and the positioning efficiency is improved.
Furthermore, the positioning rod is a stepped pin shaft, and the pin shaft is in pin connection with the positioning hole.
Has the advantages that: the stepped pin shaft is adopted, so that the phenomenon that when the pin shaft passes through the positioning hole and then drops to cause a hole to be machined of a workpiece to be machined is avoided, the workpiece moves, and therefore the quality of the hole to be machined is influenced.
Furthermore, the positioning plate is provided with a connecting hole.
Has the advantages that: the locating plate passes through the connecting hole and is connected with ordinary lathe for the locating plate is fixed, avoids driving the locating plate and removes often making dough the workpiece machining hole, improves the precision of workpiece machining hole making dough.
Furthermore, the positioning plate is provided with a hoisting hole.
Has the advantages that: because the locating plate has certain weight, hard when artifical the removal, accomplish the installation of locating plate through hole for hoist cooperation equipment, it is laborsaving.
Furthermore, the edges and corners of the positioning plate are provided with chamfers.
Has the beneficial effects that: the chamfering device has the advantages that materials of the positioning plate are reduced, and meanwhile, potential safety hazards are reduced as workers scratch workers when the workers operate the machine tool.
Furthermore, the center of the positioning plate is provided with an avoiding hole.
Has the advantages that: because the center of the workpiece is provided with the convex part, the convex part extends into the avoidance hole, so that the workpiece is easier to rotate.
