Detailed Description
In order to more clearly illustrate the utility model, the utility model is further described below in connection with preferred embodiments. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and is not to be taken as limiting the scope of the utility model.
Fig. 1 shows an embodiment of a workpiece positioning device according to the utility model. The workpiece positioning mechanism is provided with a lifting frame 1 and a placing support table 2 fixed on the lifting frame 1, wherein the placing support table 2 is used as a processing platform for fixing workpieces, and the position of the placing support table is lifted to a working area on mechanical equipment by utilizing the lifting frame so as to process the workpieces on the placing support table conveniently. By means of this design of the mechanism, the workpiece can be quickly and simply placed on the placing pallet and lifted by the lifting frame, so that the workpiece is in the correct machining position during the machining process of the machine tool.
The elevation frame can be made of, for example, welded or joined together or interconnected steel profiles, so that the elevation frame has a structurally simple design, so that the manufacturing costs are greatly reduced and the height of the elevation frame can be adjusted appropriately according to the actual requirements. In addition, the skilled person will appreciate that road wheels may be arranged at the bottom end of the elevated frame to allow easy movement of the elevated frame.
In an advantageous embodiment of the utility model, it is provided that the placement pallet 2 has at least one workpiece receiving opening 21 and that the upper end face of the placement pallet 2 is provided with a positioning element 3 which cooperates with the workpiece receiving opening 21. The number of the workpiece accommodating openings on the placing tray can be multiple theoretically, and the arrangement is that after the workpiece on one workpiece accommodating opening is processed and taken out, mechanical equipment can process the workpieces on the other workpiece accommodating openings firstly, so that the time for waiting for fixing a new workpiece on the workpiece accommodating opening is reduced, and the processing efficiency is improved.
Referring to fig. 2, the positioning assembly 3 includes a positioning pin 31, a first positioning block 32 and a second positioning block 33, and the positioning pin 31, the first positioning block 32 and the second positioning block 33 are disposed to surround the workpiece receiving opening 21.
In the embodiment shown in fig. 1, the placing pallet 2 has two left and right workpiece receiving openings 21, and the two workpiece receiving openings 21 are separated by an extending partition 22 provided on the placing pallet 2. Correspondingly, the top of the lifting frame 1 is configured as an open surface, and a horizontal side support 11 is arranged at a middle position of the top of the lifting frame 1 for carrying the extension spacer 22, and the side support can be fixed on the lifting frame by a plurality of reinforcing beams for further enhancing the supporting capability of the side support.
The purpose of arranging the workpiece accommodating port on the placing tray table is that the workpiece to be processed is not a common cylinder in shape, and a certain protruding part exists on the structural main body of the workpiece accommodating port, so that the workpiece can be placed on the placing tray table in an uneven manner if the workpiece is directly placed on the placing tray table, and the protruding part of the workpiece is accommodated through the workpiece accommodating port. And one side of the workpiece accommodating port is in an outward open-shaped design, so that the manufacturing difficulty of arranging the workpiece accommodating port on the placing support table can be reduced, and the material and the cost can be saved.
