Fixture characteristics and types of light CNC lathe manipulators

In the field of CNC machining, with the development of modern industry and the intensification of competition, new requirements have been put forward for processing efficiency, and the automation of CNC lathe workpiece loading and unloading has become one of the important needs of current manufacturers for machine tools. As an automation equipment in the database processing consumption line, the application structure of the CNC lathe manipulator is also very important, especially the impact on processing efficiency.

When machining the workpiece on the machine tool, in order to make the appearance of the workpiece reach the technical requirements such as the size of the drawing, the geometric shape and the mutual position accuracy with other appearances, the workpiece must be assembled (positioned) and clamped (clamped) before processing. CNC lathe manipulator parts fixture is usually composed of positioning element (to affirm the correct position of the workpiece in the fixture), clamping installation, tool setting guide element (to confirm the relative position of the tool and the workpiece or the direction of the guiding tool), indexing installation (so that the workpiece can complete the processing of several stations in a device, there are two types of rotary indexing installation and linear moving indexing installation), connecting elements and clamping fine (fixture base), etc.

CNC lathe manipulator fixture is used to fix the processing object in the mechanical manufacturing process, so that it occupies the correct position, and the CNC lathe manipulator fixture is used to withstand the installation of construction or detection, also known as fixture. Broadly speaking, any process in the process of installing the workpiece for speed, convenience and safety can be called the CNC lathe manipulator accessories fixture. Among them, machine tool fixtures are the most common, often referred to as fixtures.

CNC lathe manipulator accessories fixture varieties can be divided into according to the application characteristics:

1. Special fixture. Specially designed and manufactured for the clamping needs of a certain product parts in a certain process, the service object is focused, very targeted, and generally designed by the product manufacturer. Commonly used are lathe fixtures, milling fixtures, drilling dies (machine tool fixtures used to guide the cutter to drill or reaming holes on the workpiece), boring dies (machine tool fixtures used to guide the boring tool bar to boring holes on the workpiece) and accompanying fixtures (mobile fixtures used to combine machine tools on the automatic line).

2. Universal universal fixture. Such as machine vise, chuck, suction cup, indexing head and rotary table, etc., have great versatility, can better comply with the transformation of processing processes and processing objects, its structure has been finalized, size, specifications have been serialized, manipulator accessories have become a kind of standard accessories of machine tools.

3. Adjustable fixture. Dedicated fixtures that allow you to change or adjust components.

4. a combination fixture. Fixtures consisting of standardized elements of different shapes, specifications and uses, the robot accessories are suitable for the trial production of new products and for single parts, small batches and temporary tasks where products are frequently changed.
