In the manufacturing process, the robot is a very important automation device, which is used to replace the manual completion of repetitive work tasks. In the operation of the manipulator, the fixture is a crucial auxiliary tool to help the manipulator to carry out accurate positioning and fixing. For different manufacturing processes and product types, the fixture required by the robot will also be different. Therefore, for different manufacturing processes and needs, it is necessary to carry out detailed fixture demand analysis.

Firstly, the operating environment and process requirements of the manipulator are analyzed. Manipulators operate in different manufacturing environments, and the requirements for fixtures will vary. For example, in a high temperature or low temperature environment, it is necessary to choose high temperature or low temperature resistant materials to make fixtures; In the vibration or high pressure environment, it is necessary to choose a fixture with good shock resistance and pressure resistance. For different process requirements, it is also necessary to select the corresponding fixture, such as the fixture for welding needs to have good electrical and thermal conductivity, and the fixture for assembly needs to have a high degree of accuracy and rigidity.

Secondly, the manipulator's operating objects and product types are analyzed. The type and size of the products involved in the manufacturing process of the manipulator are different, and different fixtures need to be selected according to the specific situation. For example, for small-size parts, it is necessary to select a precision fixture or claw to ensure accurate positioning and clamping; For large products, you need to choose a large fixture or support frame to ensure stability and safety. In addition, for products with different shapes and structures, it is also necessary to select fixtures with different shapes and structures to match them to ensure the smooth operation of the manipulator.

The operation mode and functional requirements of the manipulator are analyzed. There are many ways of operation of the manipulator in the manufacturing process, such as grasping, rotating, flipping, etc. Different modes of operation need to choose different fixtures. For example, for products that need to be rotated, it is necessary to select a fixture or claw with a rotating function; For products that require a rollover operation, a support frame or fixture with a rollover function needs to be selected. In addition, for some special functional requirements, such as automatic recognition of product size and shape, it is necessary to select a fixture with sensor and control functions to achieve automatic operation.

To sum up, the fixture demand analysis used by the manipulator in the manufacturing process involves many aspects such as the operating environment, process requirements, product types, operation modes and functional requirements. Through the detailed analysis of these aspects, the appropriate fixture can be selected to improve the operating efficiency and accuracy of the manipulator and ensure the smooth progress of the manufacturing process. As an important auxiliary tool of the manipulator, the fixture is of great significance in the field of automated manufacturing, which needs to attract the attention and key research of manufacturing enterprises and research and development institutions.
