Problems solved by technology
The characteristic of this robot is that the machine bed, column, and beam are used as supporting parts, and the processing surface trajectory of the nozzle is formed according to the series kinematics principle of X, Y, and Z coordinate motion superposition, but the motion accuracy of the nozzle of this series robot is that each moving component Simple linear accumulation, so the motion accuracy is low, the reliability is poor, the control mechanism is complex, the structure is complicated, the weight is large, and the degree of modularization is not high, which seriously restricts the popularization and application of the rapid manufacturing process of large and complex molds

Embodiment Construction
[0033] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0034] to combine figure 1 , figure 2 , Figure 6 , Figure 6a , Figure 7 , Figure 8 It can be seen that the whole structure has two vertical guide rails 1 and two horizontal guide rails 5 . Two vertical linear motors are symmetrically installed between the vertical slide plate 2 and the vertical guide rail 1 . The moving platform 12 of the six-degree-of-freedom work platform is connected to the servo hydraulic motor 6 through the flange, and the output shaft of the servo hydraulic motor 6 is connected to the swing head swing frame 10 through the connector 7, and the swing head swing frame 10 is connected to the swing head swing shaft 8 And servo torque motor 11. The movement of the two-degree-of-freedom swing head is realized by controlling the rotation of the servo hydraulic motor 6 and the swing of the servo torque motor 11 . The six-degree...

Abstract
The invention relates to a high melting point fast metal manufacture device for an arc spraying mould, which is reasonable in structure, convenient to use, high in modulation degree and low in cost. The device is provided with a horizontal guide rail, a vertical guide rail is movably installed on the horizontal guide rail, a work platform connection frame is movably installed on the vertical guide rail, and a linear motor is respectively installed between the vertical guide rail and the horizontal guide rail and between the work platform connection frame and the vertical guide rail. The work platform connection frame is provided with a six-degree-of-freedom workbench provided with a two-degree-of-freedom swinging head, and the two-degree-of-freedom swinging head comprises a servo hydraulic motor connected with a swinging frame of the swinging head through a connecting piece. A swinging shaft of the swinging head is installed on the swinging frame of the swinging head and connected with a servo torque motor installed on the swinging frame of the swinging head, and a spray head is installed on the swinging shaft of the swinging head. The servo torque motor, the servo hydraulic motorand the linear motor are all connected with a control computer.
Description
technical field [0001] The invention relates to rapid mold shell manufacturing equipment in the advanced manufacturing field, in particular to a high-melting point metal arc spraying mold rapid manufacturing equipment. Background technique [0002] Metal arc spraying rapid molding technology is a molding technology based on "replica". It uses a physical model (or prototype) as the master mold, uses the arc as the heat source, and sprays the molten metal material through high-speed airflow. It is sprayed and deposited on the surface of the master mold to form a dense metal shell with a certain thickness, that is, the mold shell. The mold shell accurately copies the shape of the prototype and obtains the required mold cavity. After completing post-processing processes such as reinforcement, demoulding, and polishing, the rapid manufacturing of the mold can be completed. After the arc spraying mold is manufactured, it generally does not require additional machining, and can be...
