[0045] More specifically, the towed array includes: upper skeleton 01, lower skeleton 02, skeleton screw 03 and nut 05, the nut 05 is embedded and fixed in the lower skeleton 02 and forms the lower frame unit 06. The nut 05 is embedded and fixed in the lower skeleton 02 and forms the lower frame unit 06, and when the locking gun 21 locks the skeleton screw 03, the nut 05 is a fixed structure, which is beneficial to realize the automatic locking of the skeleton screw 03.

[0046] The screw locking device for the towed array assembly production line comprises the design idea of automatic assembly of the towed array. The nut 05 is embedded and fixed in the lower framework 02 in advance, and the nut 05 does not need to be fixed when the framework screw 03 is locked, thereby facilitating automatic locking of the framework screw 03.

[0047] In the embodiment, the front end support table 3 is used to provide an installation basis for the three-axis screw locking module 2 and the middle mounting rack 1. The middle mounting rack 1 is used to provide an installation basis for the pressing plate lifting drive 6 and the clamp telescopic drive 7. The framework support 8 is used to carry a plurality of lower rack units 06 (an integrated component of the lower framework 02 and the nut 05) to move up and down under the action of the carrier lifting linear drive 9, so as to realize the transfer of the lower rack unit 06 to the locking work area 32. The carrier lifting linear drive 9 is used to provide at least a vertical linear power, and when horizontal movement is required, a horizontal linear power is also required. Therefore, the carrier lifting linear drive 9 is a YZ two-axis linear module that can be directly purchased, or the carrier lifting linear drive 9 at least comprises a lifting cylinder and a translation cylinder.

[0048] The liftable upper rack top pressing plate 4 can be lifted and lowered under the action of the pressing plate lifting drive 6, and when it is lowered, the liftable upper rack top pressing plate 4 presses the upper framework 01. When it is lifted, the pressure is released, thereby providing conditions for free material discharge of the product. The pressing plate lifting drive 6 can be a cylinder or an oil cylinder. The telescopic upper rack end face clamp 5 is used to clamp both ends of the upper framework 01 during screw locking, and the telescopic upper rack end face clamp 5 can be a two-finger pneumatic clamp or a two-finger electric clamp.

[0049] The three-axis screw locking module 2, also known as an intelligent locking robot or an automatic screw locking machine, is used to realize automatic screw locking. The three-axis screw locking module 2 is used to realize locking of the framework screw 03. The three-axis screw locking module 2 can realize movement of the locking module in XYZ three-axis directions.

[0050] The middle mounting frame 1 is used for providing a mounting base. In use, the jacking and moving device carries a plurality of lower frame units 06, moves to the lower side of the three-axis screw locking module 2 through the bracket locking access hole 35, and then buckles an upper frame 01 on each lower frame unit 06 through a mechanical hand or manual work. The plate lifting drive 6 drives the liftable upper frame top plate 4 to press down, and at the same time, presses the top surface of the plurality of upper frames 01, and realizes the limiting of the upper frames 01 in the height direction. Under the action of the clamp telescopic drive 7, the telescopic upper frame end face clamp 5 on one side of each upper frame 01 moves to the direction close to the upper frame 01. The telescopic upper frame end face clamp 5 is a two-finger pneumatic clamp jaw, and the two clamp fingers 51 of the telescopic upper frame end face clamp 5 clamp the two ends of the upper frame 01, so as to realize the limiting of the two ends of the upper frame 01.

[0051] The three-axis screw locking module 2 comprises four locking guns 21 arranged in a straight line, a screw conveying unit 22 and a screw bin 23. The frame screw 03 is located in the screw bin 23. After the upper frame 01 is fixed, the gun barrels of the locking guns 21 in the three-axis screw locking module 2 move to the positions where the screws of the upper frame 01 need to be locked. The gun barrels of the locking guns 21 penetrate the screw locking access hole 41, and the frame screw 03 is conveyed from the screw bin 23 to the gun barrels of the locking guns 21 through the screw conveying unit 22, so as to realize the automatic locking of the frame screw 03. The three-axis screw locking module 2 can simultaneously lock a plurality of frame screws 03 at a time, and then moves to the next row to continue working until the frame screws 03 of the upper frame 01 are all installed. The liftable upper frame top plate 4 and the telescopic upper frame end face clamp 5 are all retreated, and the top of the jacking and moving device retreats to the lower side of the front end support table 3 through the bracket locking access hole 35.

[0052] In specific implementation, in order to ensure that the upper frame 01 is smoothly loaded, the liftable upper frame top plate 4 is in the upwardly retracted state when the upper frame 01 is loaded.

The bracket lifting linear actuator 9 is also used to drive the skeleton support 8 to extend to above the front end support table 3 through the bracket feeding access hole 36 or retract to below the front end support table 3. The bracket lifting linear actuator 9 also needs to provide linear power in the horizontal direction. In the specific implementation, the upper rack photoelectric sensor 10 is also installed on the front end support table 3. The upper rack photoelectric sensor 10 emits detection light to detect whether the upper skeleton 01 exists, and transmits the signal to the three-axis screw locking module 2 to control whether the three-axis screw locking module 2 acts, so as to avoid empty action. When a certain upper rack photoelectric sensor 10 does not detect the existence of the upper skeleton 01, the corresponding locking gun 21 does not perform the screw locking action.

The three-axis screw locking module 2 can simultaneously implement the locking of four skeleton screws 03 at a time, and then moves to the next row to continue working until the skeleton screws 03 of the fixed upper skeleton 01 are all installed.

[0076] When the first set of product fixing fixture is in the above-mentioned screw locking process, the second set of product fixing fixture is in the loading process, and when the first set of product fixing fixture screw locking is completed, it enters the loading process again. The second set of product fixing fixture is in the screw locking process, and the three-axis screw locking module 2 moves to the second set of product fixing fixture to implement bolt locking. The two sets of product fixing fixtures work alternately to avoid waiting and improve production efficiency.

[0077] After both sets of product fixing fixtures have completed the screw fastening process, the wire harness 04 is pulled along the production line direction to move a certain distance, and the fastened part is moved out of the fastening area 32. The wire harness 04 is displayed at the same time. The newly displayed wire harness 04 in the fastening area 32 is an empty wire harness without a skeleton. The upper skeleton 01 and the lower skeleton 02 are installed on the empty wire harness section. The above steps are repeated until the target length of the drag array is obtained.

[0078] More specifically, the three-axis screw fastening module 2 of this embodiment has four fastening guns 21. For example... Figure 9 As shown, the four screw fastening guns 21 fasten four parallel upper frame screw holes 011 at a time. After completion, they fasten the next set of four parallel upper frame screw holes 011. When all the frame screws 03 on one frame support 8 have been fastened, the three-axis screw fastening module 2 is moved to another frame support 8 and fastens all the frame screws 03 on that frame support 8 in the same manner, thus completing the fastening operation for that batch. The above steps are repeated when performing the next batch of fastening operations. Figure 9 The middle arrow and S1-S9 show the locking action path of the locking gun 21.
