The oiling assembly 58 comprises a first air cylinder 581 arranged on the rotating plate 57 and with a downward output end, a clamping block 582 arranged at the output end of the first air cylinder 581 and an oil gun 583 arranged on the clamping block 582, and the sheathing assembly 59 comprises a second air cylinder 591 arranged on the rotating plate 57 and with a downward output end, a connecting plate 592 arranged at the output end of the second air cylinder 591 and a first air cylinder 581 clamping jaw arranged on the connecting plate 592.

It should be noted that the nut is placed on the jig, and the nut is transferred to the feeding mechanism 3 together with the jig.

In practical use, after the feeding mechanism 3 receives the jig and the nut, the jig and the nut are transferred to the conveying line 2, then the conveying line 2 drives the jig to move to a position corresponding to the clamping mechanism 8, then the conveying line 2 stops moving, the clamping mechanism 8 clamps the nut, before the nut is clamped, the lead screw module 54 drives the sliding plate 53 to move to one side of the extracting disc 9, the manipulator 55 moves along a preset track, so that the first cylinder 581 clamping jaw corresponds to one nut sleeve, then the second cylinder 591 drives the connecting plate 592 to move downwards so that the first cylinder 581 clamping jaw grasps the nut sleeve, then the second cylinder 591 and the lead screw module 54 reset so that the oil gun 583 corresponds to the nut, then the first cylinder 581 drives the clamp block 582 to move downwards so that the oil gun 583 hits lubricating oil on the inner wall of the nut, then the rotating cylinder 56 rotates 180 degrees so that the first cylinder 581 corresponds to the nut, and then the second cylinder 591 drives the first cylinder 581 to move downwards so that the nut sleeve is inserted into the nut. Then the conveying line 2 continues to move, so that the detection mechanism 6 detects the nut sleeve and the nut assembling condition, and when the nut sleeve and the nut are not assembled properly, the poor material receiving mechanism 7 removes the product from the conveying line 2. When the assembly is qualified, the receiving mechanism receives the products in the conveying line 2.

In the design, the whole assembling device is compact in structure, and meanwhile, the nut is convenient to be sleeved in the nut, so that the working efficiency is effectively improved.

Specifically, the method comprises the following steps: as shown in fig. 6, the feeding mechanism 3 has the same structure as the non-defective product receiving mechanism 4, the feeding mechanism 3 includes a linear module 31 disposed on the frame 1 and having a conveying direction perpendicular to the conveying line 2, and a flow line 32 disposed on the linear module 31, and the linear module 31 drives the flow line 32 to correspond to the conveying line 2.

During the in-service use, the linear module 31 drives assembly line 32 to move for assembly line 32 and transfer chain 2 dislocation, and external equipment places the tool on assembly line 32 together with the nut afterwards, and linear module 31 drives assembly line 32 to move to dock with transfer chain 2 afterwards, and assembly line 32 carries the tool to transfer chain 2 together with the nut afterwards.

In the above design, the structural design of the feeding mechanism 3 and the good product receiving mechanism 4 is convenient for conveying and transferring the products.

Specifically, the method comprises the following steps: as shown in fig. 5, the conveying line 2 includes an installation rack arranged on the rack 1 and a power belt line arranged on the installation rack, the clamping mechanism 8 includes two clamping pieces which are arranged on the installation rack in the same structure and oppositely, and each clamping piece includes a fixing plate arranged on the installation rack, no. three air cylinders 82 arranged on the fixing plate, and a butting block 83 arranged on the No. three air cylinders 82.

During actual use, the jig moves along with the power belt line, when the jig moves to the position corresponding to the clamping mechanism 8, the power belt line stops moving, and then the third air cylinder 82 drives the abutting block 83 to move towards one side of the nut, so that the two abutting blocks 83 clamp the nut. After the nut and the nut sleeve are assembled, the third air cylinder 82 drives the abutting block 83 to reset.

In the design, the clamping mechanism 8 can effectively fix the nut before the nut sleeve is assembled, so that the assembled nut is stable, and the assembly precision is ensured.

Specifically, the method comprises the following steps: as shown in fig. 4, the defective material receiving mechanism 7 includes a support 71 disposed on the frame 1, a second linear guide rail 72 horizontally disposed on the vertical base, a sliding plate 73 slidably disposed on the second linear guide rail 72, a fourth air cylinder 74 fixedly disposed on the support 71 and used for driving the sliding plate 73 to slide relative to the second linear guide rail 72, a third linear guide rail 75 vertically disposed on the sliding plate 73, a second air cylinder 591 clamping jaw slidably disposed on the third linear guide rail 75, and a fifth air cylinder 77 fixedly disposed on the sliding plate 73 and used for driving the second air cylinder 591 clamping jaw to slide relative to the third linear guide rail 75, and a defective product flow line 78 for receiving a product transferred by the second air cylinder 591 clamping jaw is further disposed on one side of the support 71.

During the in-service use, when the product after the assembly is unqualified, no. five cylinder 77 drive No. two cylinder 591 clamping jaw moves down for No. two cylinder 591 clamping jaw snatchs the bad product in the transfer chain 2, and No. four cylinder 74 drive slide block 73 slides relative No. two linear guide 72 afterwards, makes No. two cylinder 591 clamping jaw press from both sides and gets the product and move to bad product assembly line 78 top, and No. five cylinder 77 drive No. two cylinder 591 clamping jaw moves down afterwards, makes the bad product placed in bad product assembly line 78 down.

In the above design, the structural arrangement and the specific implementation of the bad material receiving mechanism 7 can enable the bad products to be captured out of the production line 32 in time.

Specifically, the method comprises the following steps: as shown in fig. 3, the assembly 58 of buying oil still includes two linear bearing 584 that set up on clamp splice 582, linear bearing 584 endotheca is equipped with upper end and a guide pillar 585 of changeing board 57 fixed connection, and two guide pillar 585 lower extremes are provided with connecting block 586, the dress cover subassembly 59 still includes two linear bearing 594 that set up on connecting plate 592, no. two linear bearing 594 endotheca is provided with upper end and No. two guide pillars 596 of changeing board 57 fixed connection, and two No. two guide pillar 596 lower extremes are provided with fixed block 595.
