German CAMLOC workholding fixtures CAMLOC model CAMLOC price

CAMLOC workholding fixtures are any tools with specific functions connected to the robot edge (joint). This may include robot grippers, robot tool changers, robot collision sensors, robot rotary unions, robot pressure tools, compliance devices, robot spray guns, robot deburring tools, robot arc welding torches, robot electric welding torches, etc. Robot end-effectors are generally considered peripheral equipment of the robot, robot accessories, robot tools, and arm-end tools (EOA). Main elements: mechanism type, gripping method, gripping force, drive unit and control object characteristics, mass, shape, center of gravity position, size, dimensional tolerance, surface condition, material, strength, operating parameters, operating space environment, operating accuracy, operating speed and acceleration, clamping time.

CAMLOC workholding fixture classification

Due to the different working characteristics and structural forms of various machine tools, different requirements are correspondingly proposed for the structure of the fixtures used. According to the machine tools used, fixtures can be divided into: lathe fixtures, milling machine fixtures, drilling machine fixtures, boring machine fixtures, grinding machine fixtures, gear machine tool fixtures, and other machine tool fixtures. According to the different clamping power sources adopted by the fixtures, they can be divided into: manual fixtures, pneumatic fixtures, hydraulic fixtures, pneumatic-hydraulic fixtures, electric fixtures, magnetic fixtures, vacuum fixtures, etc. Specialized classification includes general-purpose fixtures, special-purpose fixtures, general-purpose adjustable fixtures, group fixtures, modular fixtures, and pallet fixtures. A pallet fixture is a fixture used on automatic lines. This fixture not only serves to clamp the workpiece but also becomes integrated with the workpiece to move from one station to the next along the automatic line for processing different operations.

CAMLOC workholding fixture technology

The electromagnetic chuck consists of a base housing, iron core, coil, faceplate, and junction box. Its manufacturing process is as follows: 1) Select suitable materials to weld or cast the base housing. 2) Install the iron core onto the base housing according to the type of chuck. 3) Wind the coil with the corresponding number of turns and technical parameters, dry it, and fit it onto the iron core. 4) Pour asphalt or other waterproofing materials into the interior of the base housing. 5) Manufacture the faceplate and install it together with the base housing part. The electromagnetic chuck uses DC power supply and features stability, strong suction force, and low residual magnetism. Electromagnetic chucks can be classified into standard suction chucks and high-power chucks. The suction force of standard suction chucks is 10-12 kg/cm², and that of high-power electromagnetic chucks is not less than 14 kg/cm². According to usage, they can be divided into electromagnetic chucks for grinding machines, electromagnetic chucks for milling and planing machines, electromagnetic chucks for knife grinding machines, etc.

CAMLOC workholding fixture selection

When selecting pneumatic grippers and jaw designs, these are the main factors to consider: 1) Part shape, orientation, and dimensional variations: If the object has two opposing flat surfaces, a parallel two-jaw gripper can be used to address dimensional deviation issues. For cylindrical objects, a two-jaw gripper can also be used for clamping. Note that containment or enveloping gripping requires less force. 2) Part weight: The gripping force must be sufficient to hold the object securely during the required operations. The type of jaw design must be considered when calculating the required gripping force. Please note that safety factors should be considered when selecting the required force, and air pressure is also a factor to note. 3) Accessibility: This relates both to the operation being performed and the spatial size of the gripper jaws. If work is to be performed on the exterior of the object, internal gripping is required. Scissor-type grippers are usually lower in price but require more space for jaw movement. 4) Environment: Grippers used in harsh environments or cleanrooms require corresponding designs. 5) Object retention: When air pressure is no longer supplied, the gripper will release its hold on the object, causing it to drop. For such applications, spring-assisted grippers can be used.
