Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 and fig. 2, the utility model discloses a flexible track, include track board 1 and the vacuum chuck 2 that is located track board 1 below, vacuum chuck 2 includes a plurality of and evenly arranges in track board 1 below, all is furnished with vacuum generator 3 on every vacuum chuck 2, is equipped with the solenoid valve 31 that has the check valve between vacuum generator 3's vacuum interface and vacuum chuck 2's gas vent, and two adjacent vacuum generator 3's air supply interface passes through the connecting pipe 32 and links to each other, and all solenoid valves 31 that have the check valve insert control module after connecting in parallel through the wire. The electromagnetic valve 31 with the one-way valve is a two-position three-way electromagnetic valve, and one of the passages is provided with the one-way valve, and the specific connection mode is that the passage where the one-way valve is located is accessed during vacuum pumping, airflow flows to the vacuum generator 3 from the vacuum sucker 2, and the other through passage is accessed during inflation, so that the vacuum sucker 2 is directly communicated with the vacuum generator 3. The control module mainly has power supply and control functions, and can uniformly realize the switching operation of all the electromagnetic valves 31 with the one-way valves.
The arrangement and the working process of the flexible track are as follows: firstly, the flexible track is flatly paved on the surface of a machine body, then a connecting pipe 32 is connected with a compressed air source of a factory by an air pipe, an electromagnetic valve 31 with a one-way valve is positioned at a vacuumizing station by a control module, finally, the compressed air source is started, high-pressure air is filled into each vacuum generator 3, so that the vacuum suction cup 2 gradually becomes a vacuum state and is adsorbed on the surface of the machine body, and the fixation of the flexible track is realized. It is then preferable to keep the compressed air source in operation, although even if the machine is stopped under the action of the check valve, air cannot enter the vacuum cup 2 from the vacuum generator 3, and the self-holding function of the vacuum cup 2 can be achieved within a certain period of time, but there is a possibility of air leakage from the periphery of the vacuum cup 2 over a long period of time. After the flexible track finishes working, the compressed air source is firstly disconnected, then the electromagnetic valve 3 with the one-way valve is switched to an inflation station, the vacuum sucker 2 is communicated with the outside air, and the air is inflated under the action of atmospheric pressure, so that the flexible track is separated from the machine body.
For the track plate 1, in order to adapt to the curved surface deformation of the machine body, certain flexibility is required, and meanwhile, certain rigidity is required to play a supporting role for mechanical equipment, so that the track plate 1 is preferably made of spring steel.
At present, mechanical equipment utilizing a flexible track is more, and different driving modes are provided, wherein the two driving modes are mainly adopted, one mode is that a gear rack 11 is arranged in the middle of a track plate 1, the other mode is that gear racks are arranged on two side edges of the track plate, and the driving gear on the mechanical equipment is matched with the gear racks to realize movement.
Because the air source interfaces of two adjacent vacuum generators 3 are connected through the connecting pipe 32, for convenient installation, the air source interfaces of the vacuum generators 3 are provided with the three-way valve 33, and the connecting pipe 32 is connected with the three-way valve 33 through a threaded joint. In addition, in order to judge whether each vacuum chuck 2 breaks down, can set up the atmospheric pressure inductor in vacuum chuck 2, then reflect on vacuum chuck 2 with the form of pilot lamp, can understand each vacuum chuck 2's state directly perceivedly, the equipment maintenance of being convenient for.
Further, to large-scale equipment such as aircraft, steamer, generally need longer flexible track, consider the convenience of depositing, transporting and installing, flexible track adopts multistage structure concatenation to form best, is equipped with mosaic structure at the both ends of each section, mosaic structure is including the bolt hole 12 and the bolt 13 of configuration setting at track board 1 tip to and be used for connecting wire's wire joint and be used for connecting tracheal air pipe joint.
Considering that the precision of mechanical equipment operation on flexible track is influenced to a certain extent by the roughness of track board, consequently connection structure still includes connecting plate and the screw hole 14 of setting at the track board both ends, the connecting plate is connected at the concatenation position of two sections track boards 1 and passes through the bolt fastening on screw hole 14, has guaranteed the planarization at two track boards 1 concatenation positions.
For the air pipe joint, two structural forms, namely a U-shaped joint and a Y-shaped joint, are designed in the application, wherein the U-shaped joint is only used for connecting the connecting pipes 32 of the two sections of flexible tracks, the Y-shaped joint is used for connecting the connecting pipes 32 of the two sections of flexible tracks and is connected with a compressed air source, and the general overall track can be formed by adopting one Y-shaped joint. The mounting position of the Y-shaped joint can be reasonably selected according to the positions of the flexible track and the compressed air source during specific splicing.
The existing flexible track has a certain defect in the aspect of safety, and has another defect that the whole structure is in a completely fixed form, namely the position, the angle and the like of the track are completely restricted by a curved surface of a machine body, and the track cannot be properly adjusted according to the use condition. Therefore, this practicality is adjustable in order to realize the track angle be connected through supporting structure 4 between track board 1 and the vacuum chuck 2, supporting structure 4 is the V-arrangement, and its bottom is articulated with vacuum chuck 2, and the top is passed through the screw and is connected with track board 1, and telescopic link 5 and vacuum chuck 2 are passed through at the both ends of supporting structure 4 and articulated. The track plate 1 can rotate at a certain angle by adjusting the length of the telescopic rod 5, so that different use requirements can be met.
The telescopic rod 5 can adopt various forms, and the application provides two modes, one mode is that connecting rods with different replaceable lengths are adopted, and the connecting rod with a specific length is selected according to a required deflection angle, so that the mode is low in cost; the other type is that a threaded rod with adjustable length is adopted, and long-strip adjustability is achieved through a feed screw and nut mechanism, so that the mode is high in cost and high in adaptability.
The utility model discloses an all be equipped with a vacuum generator and have the solenoid valve of check valve on every vacuum chuck for each vacuum chuck autonomous working, even wherein certain breaks down, do not influence other vacuum chuck's operation yet, and the solenoid valve that has the check valve can avoid gas reflux, even compressed air source shuts down, also enable vacuum chuck and keep vacuum state, thereby the unexpected condition that drops of flexible track is avoided appearing, and still have track board mosaic structure and angularly adjustable function, the security of whole equipment has been improved greatly, convenience and universality, have fine practicality and application prospect.
