[0002] Usually, when machining irregular workpieces, it is generally necessary to process a datum plane on the workpiece first, then use this datum plane for positioning, and then process other parts that need to be processed, such as holes and end faces; Figure 5 As shown, a reference hole 100a must be processed first, and then the workpiece 100 should be positioned and clamped using this reference hole 100a. In the absence of special fixtures, it is necessary to use measuring tools such as dial gauges, rulers, etc. to position the workpiece first. , and then use multiple clamping blocks to clamp the workpiece. This operation method is inefficient and it is difficult to ensure the dimensional tolerance of the workpiece

The invention discloses a fixture, which comprises a main seat body and a U-shaped base, wherein the U-shaped base and the main seat body are fixed on a workbench; the upper part of the main seat body is provided with a cylinder with a central through hole; the tail end of the cylinder is connected with the U-shaped base; a cylindrical pull rod can axially move to pass through the central throughhole; the front end of the cylindrical pull rod has external expanded taper and extends out of the cylinder to be positioned in front of the upper part of the main seat body; the front end of the cylindrical pull rod is sleeved with an expansion sleeve connected with locking mechanism; a positioning block is arranged on the edge of the upper part of the main seat body close to the expansion sleeve; the rear end of the cylindrical pull rod is provided with threads and extends out of the cylinder to be positioned in the middle of the U-shaped base; the thread part at the rear end of the cylindrical pull rod is connected with a nut; and a turning handle is connected outside the nut. The fixture can quickly and automatically position and clamp irregular workpieces with reference through holes.
Description
technical field [0001] The invention relates to the technical field of fixtures, in particular to a fixture for automatic positioning of irregular workpieces. Background technique [0002] Usually, when machining irregular workpieces, it is generally necessary to process a datum plane on the workpiece first, then use this datum plane for positioning, and then process other parts that need to be processed, such as holes and end faces; Figure 5 As shown, a reference hole 100a must be processed first, and then the workpiece 100 should be positioned and clamped using this reference hole 100a. In the absence of special fixtures, it is necessary to use measuring tools such as dial gauges, rulers, etc. to position the workpiece first. , and then use multiple clamping blocks to clamp the workpiece. This operation method is inefficient and it is difficult to ensure the dimensional tolerance of the workpiece. Contents of the invention [0003] The technical problem to be solved by ...
