Climbing frame punching machine It is used to control the processing of bearing cage punching window holes. It is composed of two parts: punching die (connected with punching machine) and electronic control system. The control system consists of five parts: microcomputer control part, photoelectric input circuit, electromagnet control circuit, display circuit, and stepping motor drive circuit. Climbing frame Punching machine It can process multiple surfaces after the workpiece is installed at one time, so it is required that the fixture can meet the requirements that all tools can approach all the machining surfaces in space. In addition, the supporting plate of the surrounding bearing fixture moves, raises, sinks and rotates, so the fixture should not interfere with the machine tool in any way.

The climbing frame punching machine can change the processing object by quickly changing the processing program. In order to reduce the auxiliary time for changing tooling and the waiting idle time for valuable equipment, when changing the processing workpiece, the fixture is required to have the function of rapid readjustment or replacement of positioning clamping elements. In addition, the processing time of a single piece increases due to the multi surface processing in NC processing. At this time, if the fixture is designed to be able to replace the workpiece outside the working area of the machine tool, the production efficiency can be improved.

The workpiece shall be fully positioned in the fixture, and the base fluid of the workpiece shall be strictly positioned relative to the machine tool origin, so as to meet the requirements of relative movement between the workpiece and the tool in the machine tool coordinate system. At the same time, the fixture should also be fully positioned on the machine tool, and each positioning surface on the fixture should have accurate coordinate dimensions relative to the machine tool origin to meet the requirements of positioning and installation in NC processing.

Since the climbing frame punching machine has the feature of continuous multi profile automatic processing, the requirements for the jig of climbing frame punching machine are higher than those for general machine tools in terms of precision and rigidity, which can reduce the positioning error, clamping error and deformation error of workpiece in the jig and rough machining.
