Detailed description of the invention
Be described in further detail the utility model in conjunction with the accompanying drawings and embodiments now, these accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, Figure 2 and Figure 3, a kind of automatic cap-rotating device, comprise: guide rail bracket 1, the fixed high cylinder 4 being connected to the gas pawl cylinder 2 on guide rail bracket 1 by lift cylinder 5 and being arranged on guide rail bracket 1, fixed high cylinder 4 and lift cylinder 5 all can slide on guide rail bracket 1, gas pawl cylinder 2 is provided with at least two gas pawls 3, gas pawl cylinder 2 connects servomotor 7 by Timing Belt 6, and servomotor 7 is connected with servo-control unit.The moment of rotation that servomotor 7 rotates is regulated and controled by servo-control unit, and actuator accepts torque command, and servomotor 7 reaches target torque.
Automatic cap-rotating device is primarily of range-adjustable lift cylinder 5, servomotor 7 and Timing Belt 6 transmission device, gas pawl cylinder 2 and Ding Gao positioning cylinder composition.Automatic cap-rotating device adopts servomotor 7, by Timing Belt 6 transmission, drive gas pawl cylinder 2 to firmly grasp threaded cap 9 and rotate, the screw-down torque between threaded cap 9 and suction nozzle 8 regulates and controls by selecting the servo-control unit of torque mode, actuator accepts torque command, controls servomotor 7 and reaches target torque.What this device can complete suction nozzle 8 and threaded cap 9 automatically screws assembling, can guarantee screw-down torque accurately again.In addition, the crawl of threaded cap 9 adopts three-pawl type gas pawl cylinder 2, can ensure firmly promptly threaded cap 9, avoid skidding in screwing operations.The function of fixed high cylinder 4 mainly comprises two aspects, first, rises and stretches out to ensure that threaded cap 9 screws front gas pawl cylinder 2 and has starting altitude accurately, secondly, when three-jaw cylinder firmly grasp threaded cap 9 be rotated down time, fixed high cylinder 4 is shunk back downwards immediately, guarantees the reliability screwing assembling action.
Gas pawl 3 is three, and equidistant annular branch, in gas pawl cylinder 2 bottom, can ensure the threaded cap 9 of holding with a firm grip that gas pawl 3 can be uniform and stable like this.Together with what the negative thread of threaded cap 9 and the outside thread of suction nozzle 8 can mate mutually be tightened in.
Three gas pawls 3 can be driven by gas pawl cylinder 2 and draw in or decontrol, and make three gas pawls 3 can firmly grasp threaded cap 9.Fixed high cylinder 4 is positioned at the below of gas pawl cylinder 2, and when such lift cylinder 5 drives gas pawl cylinder 2 to move downwardly to above threaded cap 9, fixed high cylinder 4 can determine that proper number of gas pawl 3 is held on threaded cap 9, ensures the accurate of reference position.
Fixed high cylinder 4 and lift cylinder 5 all vertically can move on the guide rail of guide rail bracket 1, and the gentle pawl cylinder 2 of servomotor 7 is fixed on support body jointly, and gas pawl cylinder 2 end is provided with guide wheel, and guide wheel connects servomotor 7 by Timing Belt 6.
When suction nozzle 8 and threaded cap 9 move in overlaying state and screw station in advance, photoelectric switch sender, controls two-position three way list electric control solenoid valve power on/off by PLC, makes valve realize pulse gassing, by the air-flow of threaded cap 9 both sides, threaded cap 9 is made to ajust the position above suction nozzle 8 and keep state of equilibrium.It is pre-aligned that the method realizes before suction nozzle 8 and threaded cap 9 spiral cover by air-flow, and without the need to setting up other power element, structure is simple, easy to operate.
The fundamental operation screwing assembling requires it is make suction nozzle 8 keep original position motionless, threaded cap 9 need complete the compound motion rotating and move down, its specific works flow process is: 1) when suction nozzle 8 moves to assembly station with the assembly set of threaded cap 9, lift cylinder 5 solenoid valves, vertical lift cylinder 5 drives gas pawl 3 to move down; 2) fixed high cylinder 4 solenoid valves, this Vavle switching is to the work of left position, and fixed high cylinder 4 rises the initial control position before determining gas pawl 3 rotation, and meanwhile, pneumatic valve switches to right position, and vacuum generator makes pneumatic three-jaw open by air-breathing; 3) fixed high cylinder 4 electromagnetic valve power-off, this valve returns back to right position, and pneumatic valve returns back to left position, and gas pawl firmly grasps threaded cap 9, and meanwhile, fixed high cylinder 4 declines and retracts; 4) driven by servomotor gas pawl is taken same threaded cap 9 and is jointly rotated, and completes spiral cover action; 5) when threaded cap 9 is screwed to default target moment values, the automatic stall of servomotor; 6) pneumatic three-jaw unclamps workpiece, and fixed high cylinder 4 rises simultaneously; 7) height detection cylinder moves down, and detects spiral cover quality.
Above according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, related personnel in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification sheets, must determine technical scope according to right.
