Detailed Introduction

Here are some typical design structures:

• Simple positioning structure (positioning pin)
Mainly used in the main positioning pin position.
• Simple support clamping (clamp)
• Write-off (bolt)
It is mainly used in the main line, to the compound line and the main positioning of the bottom line.
• STOPPER limit structure
In order to prevent the compression force or impact caused by too large piecework deformation or scratch the surface of the piecework; Clamping arm plate thickness direction has accuracy requirements (positioning pin); The length of double turning mechanism or rocker arm is too large; When the Angle of the supporting surface is too large; There is a larger eccentric distance indenter.
• PIN CLAMP
Pin and piecework non-interference – turn point and workpiece in a line; Must have a finite STOPPER.
• HLINK structure
When the opening height of the clamping arm is limited and the opening Angle is required to be large, or the movement trajectory of the clamping arm is limited, we should consider using H-LINK, which is different from ordinary Link in its use. We should choose cylinders with CYL BRACKET, which have no swing during movement, and use anti-bracket to fasten the cylinders.
• Secondary SWING structure (double flip)
Double BASE fixture
In addition to the typical structure, there is a flexible combination of quick change jig — double BASE plate clamp, which can greatly shorten the time of jig replacement adjustment and reduce the production cost; The use of the BASE rotating table in the secondary assembly fixture makes the intelligent high flexibility of the fixture become a reality. This fast switching mode greatly shortens the time of fixture replacement and debugging and reduces the production cost.
Double BASE fixture features:
The double BASE fixture has the advantages of simple structure, few assembling links and good rigidity, easy to switch models, product upgrading and automatic processing needs, its main characteristics include:
1) Double BASE fixture has universality, the fixture system has enough flexibility, can adapt to the processing requirements of different models, the overall line body can be reused.
2) The double BASE fixture has simple structure, convenient assembly and disassembly, and is conducive to rapid switching of subsequent models.
3) Double BASE fixture has enough strength and stiffness, fixture assembly, switching process can effectively ensure the machining accuracy of parts.
4) The BASE specifications of double BASE fixtures should be unified, adjustable for repeated use, and computerized for assembly and management.
Composition of Double BASE fixture:
The double BASE fixture is composed of two parts: the fixture line body part and the special fixture. The fixture line body part is composed of the fixture general part and the standard components. The special fixture part depends on the mechanism and use of the product parts.
The structure
1. Fixture wire body
The basic components of double BASE fixture include fixture universal line body, fixture frame and standard matrix BASE surface (see Figure 2);
2. The brackets
The main components of jig skeleton include a variety of gaskets, gaskets and corner seats;
3. Positioning parts between components and components of the real positioning of the piecework
It includes a variety of positioning blocks, positioning pins, positioning supports and profile lighting.
4. The fasteners
It includes standard pins and column pins, which are the main parts used to connect two BASE boards.
Technical requirements for fixture
In addition to the corresponding technical requirements of the general fixture, the following technical requirements should be considered in the design stage of double BASE fixture:
▲ Jig BASE and support seat
The main structure of the jig line is designed in accordance with GB2804, and the main components are made of high quality low-carbon alloy steel. After burglarizing and quenching, the surface hardness of the components requires HRC to reach 58 ~ 65, and the internal hardness to reach HRC35 ~ 40, so as to ensure that the jig base has enough strength, toughness, wear resistance and stability.
The main dimensional accuracy of fixture components is the same as the general fixture, reaching ISO6 ~ 7 level can, the tolerance of the horizontal positioning hole and the datum surface is ±0.05 mm, the tolerance between the positioning hole and the positioning hole is ±0.02 mm, the datum surface roughness is 1.6 μm.
The main BASE plate aperture has D28 and D16 two series. On the high-precision table surface, the circular holes of D28 are evenly distributed every 100 mm or φ16 mm every 50 mm. These holes can be used to join positioning modules and fixture connections of various functions.
