The combination of the truss manipulator and the vertical CNC machining center can realize the automatic grasping, loading, unloading, clamping, shifting and turning of the workpiece, and sequential processing of the workpiece in the CNC machining process, which can greatly save Reduce labor costs and improve production efficiency. It is especially suitable for the processing of large batches and small parts, such as bearing sleeves (seats), motor end covers, additional turbines, commutators, brake discs, automotive gearbox gears, metal stamping structural parts, etc.

What is the Truss Manipulator？

The truss manipulator, also known as the gantry robot or the truss robot, can realize automatic control, and the truss manipulator can be repeatedly programmed based on the XYZ Cartesian coordinate system in space. It has a higher degree of freedom and is suitable for automation equipment for different tasks. The truss-type manipulator refers to the automatic equipment for automatic loading and unloading, automatic clamping, automatic chip blowing, and automatic return of the finished parts to the silo for the processed parts of the CNC lathe. It completely replaces the manual operation. It saves human resources and is a mature product of "machine substitution".

The truss manipulator is a gantry structure, based on the rectangular X, Y, Z three-coordinate system, which automatically grabs, hoistes, transports, stacks, and stacks the component or product according to the set program. Fully automatic industrial equipment.

According to the number of beams, the truss manipulator is divided into single-beam truss manipulator and double-beam truss manipulator; according to the movement trajectory of the required product, it can be divided into two-axis, three-axis, four-axis, five-axis truss manipulator, etc.

The components of the truss manipulator have three parts: the main body, the drive system and the control system. It can realize loading and unloading, component turning, component reordering, etc., and integrates processing technology. Its main function is to make machine tool manufacturing separate from manual work and realize complete automation.

What is a vertical CNC machining center？

Vertical CNC machining center refers to the machining center where the axis of the spindle is perpendicular to the workbench. It is mainly suitable for processing complex parts such as plates, discs, molds and shells. The vertical machining center can complete the processes of milling, boring, drilling, tapping and thread cutting. The vertical CNC machining center has at least three axes and two linkages, and generally three axes and three linkages can be realized. Some can carry out five-axis and six-axis control. The height of the column of the vertical CNC machining center is limited, and the processing range of box-type work pieces should be reduced, which is the shortcoming of the vertical CNC machining center. However, the work piece clamping and positioning of the vertical CNC machining center are convenient; the movement track of the cutting tool is easy to observe, the debugging program is convenient to check and measure, and the problem can be found in time, and the machine can be stopped for processing or modification; the cooling condition is easy to establish, and the cutting fluid can directly reach the tool and the processing surface. ; The three coordinate axes coincide with the Cartesian coordinate system, and the intuitive feeling is consistent with the viewing angle of the drawing. Chips are easy to remove and fall, and avoid scratching the processed surface.

Truss Manipulator Applied in Vertical CNC Machining Center

It is certain is that the vertical CNC machining center can be equipped with a truss manipulator. MAKCNC's truss manipulator is widely used in vertical CNC machining centers, horizontal machining centers, and CNC lathes. Common vertical machining centers generally process large work pieces, so they are generally equipped with heavy-duty truss manipulators. The load generally ranges from a few kilograms to dozens of kilograms, and the weight of tooling and fixtures is generally more than 100 kilograms. Considering the load of the work piece itself, the weight of the tooling should also be considered.

The truss manipulator matched with the vertical CNC machining center is generally a truss production line, which is used to realize the connection of multiple vertical machining centers. Compared with the robot plus the seventh axis, the truss manipulator production line uses the upper space of the vertical CNC machining center. It does not occupy the space of the operation surface of the vertical CNC machining center, saves space, and is also very convenient for maintenance, so it is still relatively common in practical applications. MAKCNC has done heavy-duty truss manipulators to transfer products with a maximum weight of more than 5 tons, so for In vertical machining, the weight is not a problem for the truss manipulator. The main problem is that the machining center belongs to the cutting process. Therefore, the influence of iron filings on the clamping needs to be considered when doing automatic transformation. At the same time, the tooling should adopt the type with airtight detection. Tooling to ensure error prevention and safety issues throughout the automation process.
