Description

Technical Field

[0001] The utility model relates to the technical field of processing tooling, in particular to a high-precision harmonic four-axis turntable. Background Art

[0002] The harmonic four-axis turntable is a high-end precision equipment that uses the harmonic drive principle and is equipped with a related control system to achieve precise positioning and angle transmission. It is often used in machining centers to extend the machine tool's processing technology from the existing 3 axes to 4 axes.

[0003] At present, the traditional four-axis turntable drives the flange to rotate through a worm gear, which has low precision, complex structure and difficult assembly and maintenance; therefore, the ordinary harmonic four-axis turntable can only complete the cutting work of conventional steel and aluminum products.

[0004] At the same time, the control box of the current four-axis turntable is mostly located on the side of the turntable box, that is, the axis of the flange is perpendicular to the axis of the drive device rather than parallel. Such a structure results in low transmission accuracy and poor load-bearing capacity. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a high-precision harmonic four-axis turntable which can be suitable for heavy-load processing occasions and ensure dynamic cutting accuracy at the same time.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a high-precision harmonic four-axis turntable, comprising a base plate; a box body is arranged on the base plate, and a transmission part, a cover plate and a flange are arranged in sequence on one side of the box body; a driving device is arranged on the other side of the box body; the transmission part is connected to the driving device, thereby driving the rotation of the output end flange.

[0007] Furthermore, the transmission part described in the utility model is a high-precision harmonic reducer, and the transmission part includes a flexible wheel, a rigid wheel, a wave generator and a cross roller bearing; the end of the wave generator is connected to the driving shaft of the driving device.

[0008] Furthermore, a support column is provided at the bottom of the driving device described in the utility model.

[0009] Furthermore, the bottom plate of the utility model has a boss, and the box body and the cover plate are arranged on the boss; and mounting platforms are respectively arranged on both sides of the boss.

[0010] The beneficial effect of the utility model is that it solves the defects existing in the background technology. Compared with the existing technology, it has the advantages of high precision, high transmission efficiency, fast response speed, simple structure and easy maintenance; and compared with the traditional turntable, it adopts a high-precision harmonic reducer transmission design and utilizes the advantages of the four-axis turntable itself to achieve the processing and processing accuracy of parts with more complex shapes.

[0014] Now the utility model is further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0015] like Figure 1-Figure 2 A high-precision harmonic four-axis turntable shown in the figure includes a base plate; a box body is arranged on the base plate, and a transmission part, a cover plate and a flange are arranged in sequence on one side of the box body; a driving device is arranged on the other side of the box body; the transmission part is connected to the driving device, thereby driving the rotation of the output end flange.

[0016] The transmission part is a high-precision harmonic reducer, which includes a flexible wheel, a rigid wheel, a wave generator and a cross roller bearing; the end of the wave generator is connected to the driving shaft of the driving device.

[0017] High-precision harmonic reducer is used to replace the traditional worm gear transmission structure. The unique tooth shape and cam profile design achieves the advantages of high precision, high efficiency and small interference ability. The harmonic reducer is easy to assemble and maintain. At the same time, the axis directions of the drive device, transmission part and flange are parallel, which can better ensure the accuracy, efficiency and response speed of transmission.

[0018] A support column is provided at the bottom of the driving device to ensure the stability of the transmission during use; similarly, the bottom plate has a boss, and the box body and the cover plate are arranged on the boss; mounting platforms are respectively provided on both sides of the boss; adding a mounting platform to the bottom plate can provide better stability during installation.

[0019] Compared with the existing technology, the design of this high-precision harmonic four-axis turntable is simpler in structure, faster in response speed, smaller in size, higher in transmission accuracy, larger in load-bearing capacity and easier in maintenance than the traditional worm gear turntable.

[0020] The above description only describes the specific implementation methods of the utility model. Various examples do not limit the essential content of the utility model. Ordinary technicians in the relevant technical field can modify or deform the specific implementation methods described above after reading the description without departing from the essence and scope of the utility model.
