Description

Workpiece positioning device

In particular, the present invention provides a workpiece positioning device that can adjust the displacement of the angular position and the size position to position the workpiece, thereby reducing the configuration cost and improving the usability.

Press, the metal processing machine is equipped with a worktable for mounting the workpiece, and the workpiece is positioned on the worktable by an appropriate positioning method, and the workpiece can be subjected to milling, drilling or grinding.

Referring to Figures 1 and 2, it is a workbench 10 of a conventional processing machine. The table top of the table 10 is provided with six lanes extending from the inside and the outside at each equally angular position (e.g., 60 degrees). The T-shaped groove 101 is provided with a tightening nut 11 in at least three T-shaped grooves 101 for locking and fixing the workpiece; when performing the machining operation, the system can be shaped according to the size of the workpiece and the workpiece. For the processing surface and other conditions, an appropriate positioning method is selected to perform a machining operation such as milling, drilling or grinding on the workpiece; for example, a grinding process of a tubular workpiece 20 is performed at an aliquot angle of one end (eg 60 degrees) a plurality of class slots 201 and screw holes 202 are pre-processed for assembling other components. When the workpiece 20 is positioned on the table surface of the table 10, the plurality of class slots 201 and the screw holes 202 are formed. The aliquot angle position is the same as the bisector angular position of each T-slot 101 of the table 10, so that the plurality of class slots 201 or the screw holes 202 of the workpiece 20 can be directly used for positioning; The slot 201 is taken as an example, because the various slots 20 of the workpiece 20 and the work Angularly equidistant T-slot 101 of each of the same 10 to 60 degrees, and can be straight The workpiece 20 is placed on the table top of the table 10, and at least three class slots 201 of the workpiece 20 are aligned with the pressing nuts 11 in the T-shaped grooves 101 of the table 10, respectively. And the workpieces 20 are positioned on the table top of the table 10 by the bolts 12, and the workpieces 20 are positioned on the table tops of the table 10, and the workpieces 20 can be Grinding operations.

However, due to the variety of workpieces, the class slot or screw hole of the workpiece and the T-slot of the table are not necessarily the same angular position, when the workpiece slot or screw hole and the T-slot of the table When the position of the aliquot is different, the positioning fixture is used together to position the workpiece; as shown in Figures 3 and 4, for the grinding process of another tubular workpiece 20a, the workpiece 20a is attached to one end. Each of the equally angular positions (for example, 72 degrees) is pre-machined with five class slots 201a and screw holes 202a for assembling other parts; due to the bisector angular position of the five-stage slot 201a and the screw hole 202a ( 72 degrees) is different from the bisector angular position (60 degrees) of each T-slot 101 of the table 10, so when the workpiece 20a is positioned on the table surface of the table 10, it must precede the table 10 of the table 10. A positioning fixture 13 is affixed to each of the pressing nut 11 and the bolt 12a. The positioning fixture 13 is provided with a class slot 132 which is equal to the angular position (60 degrees) of each T-shaped slot 101 of the table 10. , the fixture can be set on the at least three class slots 132 with the bolt 12a and the tightening nut 11 locking frame 3. The positioning fixture 13 is provided with a locking hole 131 which is equal to the angular position (72 degrees) of the workpiece slot 20a and the screw hole 202a of the workpiece 20a, and at least three class slots of the workpiece 20a. The hole 201a is respectively inserted into the locking hole 131 of the positioning fixture 13 by the bolt 14 to position the workpiece 20a on the positioning fixture 13, so that the workpiece 20a can be ground and processed; As described above, since the workpiece has many styles, when the position of the workpiece slot or the screw hole is different from the position of the T-slot 101 of the table 10, the positioning fixture must be replaced. Not only increase The cost of configuration also causes troubles in use and affects processing efficiency.

In addition, when there is no class slot or screw hole in the workpiece, the workpiece is otherwise positioned; as shown in FIG. 5, the workpiece 20b of the class ring 201b is taken as an example, and is attached to the table 10 At least three pressure plates 15 are disposed on the table, and one end of each of the pressure plates 15 is pressed against the class ring 201b of the workpiece 20b, and is respectively locked by the bolts 12b to the pressing nuts 11 to position the workpiece 20b. The workpiece 20b can be polished on the table surface of the table 10; however, the position of the platen 201b pressed against the workpiece 20b by the platen 15 can be not divided by the T-slots 101 of the table 10. The limitation of the angular position is because the pressure plate 15 is directly pressed against a part of the workpiece 20b to be processed, and the machining of the workpiece 20b is hindered. For the workpiece 20b whose surface needs to be completely processed, the pressure of each pressure plate 11 must be The processing position of the subsequent position is increased to meet the processing requirements, which causes trouble in the processing procedure.

In order to solve the above drawbacks, the workpiece is magnetically positioned; as shown in Fig. 6, it is provided on the table 10 of the table 10 with a magnetic ring 16 attached to the magnetic ring 16 Each of the T-shaped slots 101 of the same table 10 is provided with a plurality of class slots 161 at equal angles (for example, 60 degrees), and is tightly locked by the bolts 12c to the T-shaped slots 101 of the table 10, respectively. The nut 11 is fixed to the table surface of the table 10, and the workpiece 20b can be placed on the magnetic ring 16, and the workpiece 20b can be magnetically positioned by the magnetic ring 16. The workpiece 20b is subjected to a grinding operation; however, the magnetic positioning method using the magnetic ring 16 does not limit the processing range. However, the magnetic ring used in the workshop has various specifications, and various types of slots provided by different sizes of the magnetic ring are The angulated angular positions of the T-shaped grooves 101 of the table 10 are not necessarily the same. When the positions of the slots of the magnetic ring are different from the positions of the T-shaped grooves 101 of the table 10, it is necessary to be on the table. 10 is also equipped with a special configuration of the positioning fixture, so that the magnetic ring can be locked to the positioning fixture The above, in turn, increases the cost of the configuration and causes troubles in use, which affects the processing efficiency.

In view of this, the inventor has been engaged in research and development and production experience of related industries for many years, and has conducted in-depth research on the problems currently faced. After long-term efforts and research, he finally developed a workpiece positioning device for the processing machine table.
