Automatically tool-changing numerical-control horizontal key-mirror punch indexing table

Abstract

The invention relates to an automatically tool-changing numerical-control horizontal key-mirror punch indexing table. A locating sleeve is arranged below the table, and a matching locating pin is arranged in the locating sleeve; the locating sleeve is fixedly arranged on a clamping hydraulic cylinder on the circumference of the table; a first piston is arranged in an inner cavity of the clamping hydraulic cylinder; a central hydraulic cylinder is arranged on the table, and a pipeline is connected with the lower end of the central hydraulic cylinder; a thrust screw is arranged above a second piston and is matched with a thrust shaft sleeve, and a first bearing is arranged on the thrust shaft sleeve; a rotary table seat is arranged between the table and a machine body; a hex head screw is arranged on the thrust shaft sleeve and is also arranged in a rotary table shaft; a third piston is arranged between the rotary table seat and the table; a third bearing is arranged at a connection part between the central hydraulic cylinder and the thrust shaft sleeve. The automatically tool-changing numerical-control horizontal key-mirror punch indexing table has the advantages that the working is reliable, the price is low, the flexibility is relatively higher, the production efficiency is improved, and the investment of one-time fixed assets is reduced; after a radial clearance in a table rotary shaft is eliminated, the table rotary shaft is clamped again, so that the indexing location precision of the table is improved.

Description

technical field [0001] The invention relates to a digitally controlled horizontal key-mirror bed indexing workbench for automatic tool change. Background technique [0002] Punching machines are punching equipment with a large volume and wide range in the electromechanical industry. At present, two-coordinate CNC punching machines developed on the basis of ordinary punching machines are widely used. The outstanding advantages of this type of CNC machine tools are automation and flexibility, and can adapt to various Complex punching parts processing requirements, but in actual production, there are many parts that need to process many, many holes on the same circumference. Although two-coordinate tax-controlled punching machines can be used for the processing of such holes, the price of such machine tools Expensive, complex structure, high use and maintenance costs, large one-time investment, small and medium-sized enterprises generally cannot afford it, if ordinary punching ...

[0002] Punching machines are punching equipment with a large volume and wide range in the electromechanical industry. At present, two-coordinate CNC punching machines developed on the basis of ordinary punching machines are widely used. The outstanding advantages of this type of CNC machine tools are automation and flexibility, and can adapt to various Complex punching parts processing requirements, but in actual production, there are many parts that need to process many, many holes on the same circumference. Although two-coordinate tax-controlled punching machines can be used for the processing of such holes, the price of such machine tools Expensive, complex structure, high use and maintenance costs, large one-time investment, small and medium-sized enterprises generally cannot afford it, if ordinary punching machines are used, although the machine tool is simple, the use and maintenance costs are low, and the one-time investment is low, but this kind of machine tool The processing quality is low, and quality problems are prone to occur. At the same time, because the workpiece needs to be marked or a special fixture is designed before processing, the part manufacturing cycle is long and the productivity is low. Therefore, the research and manufacturing department has a simple structure, reliable operation and low price. It is necessary to replace the expensive two-coordinate punching machine and the ordinary punching machine with high production efficiency and high processing quality. At the same time, the workbench The radial gap in the rotating shaft cannot be eliminated, the clamping effect is poor, and the indexing and positioning of the table cannot achieve the desired accuracy
