Can you distinguish between fixtures and fixtures?

Due to similar usage methods, fixtures and fixtures are often easily confused and even misused by people.

The focus of fixtures is on work and guiding tools.

A large category of tools in carpentry, ironworking, fitters, machinery, electrical control, and some other handicrafts, mainly used to help control position or movement (or both).

The fixture is mainly used to fix it in a fixed position.

Some devices have both functions (manipulation and guidance tools) and are also called fixtures. However, if they are only held without guidance tools, they are called "fixtures" rather than "fixtures"

Generally speaking, any device used to quickly, conveniently, and safely install workpieces in any process during the machining process can be referred to as a fixture.

Such as welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc. It is more common in these fixtures, usually referred to as fixtures.

When processing workpieces, in order to achieve the dimensions, geometric shapes, and relative positional accuracy with other surfaces specified in the drawing, the workpiece must be installed (positioned) and clamped (clamped) before processing. Calipers generally include positioning components (to determine the correct position of the workpiece in the caliper), fixture devices, tool alignment devices (to determine the relative position of the tool and the workpiece or guide the direction of the tool), indexing devices (to enable the workpiece to complete processing at multiple workstations in one installation, and indexing devices are divided into rotary indexing devices and linear moving indexing devices), connecting components, and calipers (caliper base).

According to the characteristics of use, fixture types can be divided into:

According to the processing characteristics of workpieces, the types of fixtures are also different. Taking the existing fixtures in industry as an example, during the processing, multiple workpieces can be clamped simultaneously, and different types of workpieces, such as pressure plates, positioning pins, reference blocks, pressure cylinders, and other small parts, can be designed on the same set of fixtures. In production operations, only partial parts need to be replaced to achieve the elastic function of quick line changing.

1. Universal universal fixture. The vice, chuck, suction cup, indexing head, and rotating workbench on the machine.

2. Special fixtures. Specially designed and manufactured to meet the clamping requirements of a certain product component in a certain process, with clear service targets and strong targeting. Generally, the product manufacturing plant designs and manufactures it independently.

3. The fixture can be adjusted. A specialized fixture for parts that can be replaced and adjusted.

4. Combination fixture. A fixture with standard components of various shapes, specifications, and uses, used for single piece, small batch production, and temporary work in the trial production of new products and frequent product replacement.
