Description

Liftable formula swivel work head Technical Field The invention belongs to the field of industrial automation equipment, and particularly relates to a lifting rotary workbench. Background In the fields of modern industrial automatic production, precision machining, material handling, detection test and the like, a liftable rotary workbench is used as core auxiliary equipment to bear key tasks such as workpiece positioning, posture adjustment, multi-station switching and the like, the structure rationality, space suitability and operation and maintenance convenience of the liftable rotary workbench directly influence the efficiency, precision and operation cost of the whole production or operation system, and the liftable rotary workbench is an important basic component for pushing automatic equipment to develop compactification, high efficiency and convenience. Along with the transformation of industrial production to the direction of refinement and intensification, in particular in space limited scenes such as small-size processing workshops, precision laboratories, automatic production lines and the like, higher requirements are put forward on the structural compactness of the liftable rotary workbench, the lifting and rotating composite function is stably realized, and the longitudinal height control and the bottom space utilization rate of the device are also considered, so that the integrated installation and later maintenance requirements of various equipment are adapted. At present, the existing lifting rotary workbench is generally realized by adopting a structural design that a cylinder is driven to combine with gear meshing, wherein the cylinder is arranged at the central position of the bottom of the workbench, a bracket at the bottom of the turntable is pushed to drive a gear of a top cover assembly of the workbench to be out of engagement, so that the rotation limit is relieved, the lifting action of the workbench is realized, and after the workbench is lifted in place, the gear is meshed again, positioning is completed, and rotary operation can be carried out. Meanwhile, a driving motor for driving the workbench clamp to clamp and loosen the workpiece is also mostly arranged at the bottom, namely, the workbench is fixed below the workbench, and power is transmitted to the clamp through a transmission structure, so that synchronous action of the clamp is realized. The prior structural design can basically meet the core function requirements of lifting and rotating, but exposes a plurality of technical defects which are difficult to overcome in the practical application process, and severely restricts the suitability and the practicability of the prior structural design. The most outstanding problems are that the whole longitudinal height of the device is higher, the occupied amount of the bottom space is overlarge, on one hand, the cylinder is fixed at the center of the bottom of the workbench, the self height of the cylinder is added with the installation space of the bracket, the longitudinal size of the workbench is directly increased, on the other hand, the motor for driving the clamp and the matched transmission structure are also installed below the workbench, the longitudinal height is further overlapped, the arrangement of the motor and the transmission assembly occupies a large amount of space at the bottom of the workbench, and the longitudinal volume is obviously increased. The negative effects brought by the structural defects are quite remarkable, when the equipment is integrally installed, the working table is difficult to adapt to a low installation space due to the excessively high longitudinal height, the application of the working table in a production scene of miniaturization and high-density layout is limited, the working table is contrary to the development trend of the compactness of modern industrial equipment, in the later maintenance process, the bottom is completely occupied by a cylinder, a motor and a transmission structure, the core components are difficult to be contacted by maintenance personnel, whether the maintenance of the cylinder, the replacement of a sealing element or the maintenance of the motor and the debugging and lubrication of the transmission structure are required to be firstly disassembled, the operation is complicated, the time and the labor are wasted, the maintenance cost and the downtime are greatly increased, and the operation stability and the service life of equipment are reduced. Along with the continuous promotion of industrial automation level, the market is urgent to the demand of space suitability, fortune dimension convenience and precision stability of liftable formula swivel work head increasingly, and current structure has not yet satisfied the diversified demand of practical application scene, consequently, research and development one kind can effectively reduce vertical height, reduce bottom space occupation, guarantees simultan
