In the process of machining, welding, heat treatment, inspection, assembly and other processes of mechanical manufacturing, in order to install the processed workpieces and make them occupy the correct position, to ensure the quality of parts and products, and to improve production efficiency, the process equipment used is called For the fixture. Dongguan precision jigs and fixtures Jig processing provide you with excellent products and services.
When brass machining a workpiece on a machine tool, you must use a fixture to clamp the workpiece, and install the workpiece, which is to determine the correct position of the workpiece relative to the tool on the machine tool. This process is called positioning. Clamping the work piece firmly means applying external force to the work piece so that it can be reliably clamped at the determined position. This process is called clamping. The whole process from positioning to clamping is called clamping.
Dongguan precision fixture jig processing
There are two clamping methods for workpieces: aligning clamping method and fixture clamping method:
(1) The workpiece clamping method is based on the relevant surface of the workpiece or the specially drawn line marks as the alignment basis. Use a scribe or indicator to correct the workpiece, position the workpiece correctly, and then clamp the workpiece for processing.
(2) The fixture clamping method is to locate and clamp the workpiece by the fixture to ensure the correct position of the workpiece relative to the tool and the machine tool.
The fixture used when processing the workpiece on the machine tool is called the machine tool fixture. The main function of Dongguan Precision Fixture Fixture Jig processing machine tool fixture is to complete the clamping work of the workpiece. The quality of the workpiece clamping situation will directly affect the machining accuracy of the workpiece.
Machine tool fixtures have a direct impact on processing quality, productivity and product costs. Therefore, the time spent by companies on fixture design and manufacturing, whether it is to improve existing products or develop new products, has a relatively large proportion in the production cycle. In the machining process, the geometric accuracy of the workpiece mainly depends on the relative position of the workpiece to the machine tool. Strictly speaking, only the correct relative relationship between the machine tool, cutting tool, fixture and the workpiece can be guaranteed to ensure the relative machining of the workpiece surface. Position accuracy.
Obviously, the basic requirement of precision CNC machining fixture jig processing for machine tool fixtures is to position the workpiece correctly and securely fix it in a given position. Therefore, in addition to ensuring sufficient manufacturing accuracy, machine tool fixtures should also have sufficient rigidity to resist deformation and vibration that may occur during processing.
