DETAILED DESCRIPTION

[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] like Figure 1 , Figure 2As shown, the automatic feeding double-axis tightening machine for end cover bolts comprises a tooling stand 1, a tightening mechanism 2 and an electric control system. A tightening station 11 for automatically tightening and assembling workpiece bolts is arranged inside the tooling stand 1. A bolt mechanism 3 for automatically sorting and feeding bolts is arranged outside the tooling stand 1. The tightening station 11 has a tooling tray for installing the workpiece inside and driving it to move. A nail feeding machine 4 for automatically feeding bolts is arranged between the bolt mechanism 3 and the tooling stand 1. A long and short nail detection mechanism 5 for detecting the length of bolts is provided, a lifting and positioning mechanism 6 for positioning and lifting the workpiece is provided in the tooling stand 1, and a clamping mechanism 7 for clamping the workpiece is provided in the tooling stand 1. The lifting and positioning mechanism 6 and the clamping mechanism 7 are respectively located above and below the tightening station 11. The bolt mechanism 3, the nail feeding machine 4, the long and short nail detection mechanism 5, the lifting and positioning mechanism 6, the clamping mechanism 7 and the tightening mechanism 2 form automatic feeding and tightening of bolts under the control of the electronic control system.

[0023] The structure is simple and innovative, changing the traditional manual tightening method of bolts and nuts and adopting an automated bolt tightening method, effectively reducing manual labor intensity and improving the efficiency and quality of bolt tightening of mechanical parts.

[0024] This end cover bolt automatic feeding double-axis tightening machine is a fully automatic equipment, which automatically feeds and tightens bolts when the end cover and the shell are assembled. The whole machine consists of a tooling stand 1, a tightening mechanism 2, a three-dimensional servo module 8, a clamping mechanism 7, a lifting and positioning mechanism 6, a long and short nail detection mechanism 5, a nail separator, a nail feeder 4, a bolt mechanism 3, and an electronic control system. The silo capacity of this machine is 5L, and the bolts are stored in the silo of the bolt mechanism 3. The nail feeder 4 is used to sort and feed the bolts. When the bolts in the nail feeder 4 are insufficient, the silo automatically feeds the bolts into the nail feeder 4. The long and short nail detection mechanism 5 is used to distinguish between M8X16 and M8X20, and when the varieties are different, it is used to prevent the bolts from being mixed. When the variety is changed, the corresponding program needs to be switched, the bolts need to be manually cleaned, and the corresponding length of the bolts need to be replaced.

[0025] Working steps

[0026] 1. The workpiece is installed on the corresponding tooling pallet, the accompanying tooling pallet enters the workstation, the pneumatic blocker 10 blocks the limit position, the photoelectric switch confirms the presence of the workpiece (if there is no tooling, the accompanying tooling pallet is automatically released), and the lifting and positioning mechanism 6 positions and lifts the accompanying tooling;

[0027] 2. The bolts are automatically delivered to the gun head by the nail feeder 4, and the three-dimensional servo module 8 drives the tightening mechanism 2 to automatically tighten the bolts on the workpiece end cover. After the specified torque is reached, the tightening mechanism 2 returns to its position, and the nail feeder 4 automatically delivers the bolts. After the bolts are delivered to the position, the three-dimensional servo module 8 drives the tightening mechanism 2 to tighten the next group of bolts, and tighten all the bolts in sequence;

[0028] 3. After tightening is completed, the tightening result value is displayed on the human-machine interface 13 (if the tightening torque is unqualified or the bolt is missed, the equipment will automatically alarm), the tightening machine mechanism returns to its original position, and the positioning jacking mechanism descends back to its original position.

[0029] Preferably, the tooling stand 1 is provided with a three-dimensional servo module 8 for driving the tightening mechanism 2 to move and tighten the bolts on the workpiece in sequence. The three-dimensional servo module 8 and the tightening mechanism 2 are both in number, and are respectively located on both sides of the tightening station 11 and have corresponding structural arrangements. The tooling stand 1 is also provided with a nail dividing mechanism 9 that cooperates with the long and short nail detection mechanism 5 and is used for dividing and conveying materials to the corresponding tightening mechanism 2.

[0030] Preferably, pneumatic blockers 10 for blocking and limiting the workpiece are provided on both sides of the tightening station 11 . The workpiece is fixedly mounted in the tooling pallet and is blocked and limited by the pneumatic blocker 10 as the tooling pallet enters the tightening station 11 .

[0031] Preferably, in order to facilitate manual observation and operation, the electric control system includes an electric control cabinet 12 for automatic control and a human-machine interface 13 for manual operation, and the human-machine interface 13 is electrically connected to the electric control cabinet 12 .

[0032] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
