As shown in fig. 1 and 2, the automatic ring assembling apparatus of the present invention is used for assembling a ring 8 to a workpiece 9. Wherein the ring member 8 is ring-shaped and has a certain elasticity, such as a weld ring. And the workpiece 9 is provided with a hole groove 91, the hole groove 91 penetrates through the workpiece 9, a boss 92 is formed on the inner wall of the hole groove 91, and the ring member 8 needs to be assembled on the boss 92, such as a main valve seat before brazing.

A first feeding assembly 1 for transporting the ring 8 to the assembly; the second feeding assembly 2 is used for conveying the workpiece 9 to the device assembly; and the assembly component clamps and places the ring member 8 in the hole groove 91 of the workpiece 9, thereby realizing the assembly of the ring member 8.

Typically, the first feeding assembly 1 is a vibrating plate, which is vibrated by vibration along the ring 8 to the feeding plate 6 for clamping the assembly. And the second feeding assembly 2 is a vibrating disk and a feeding push rod, the vibrating disk vibrates the workpiece 9 to one side of the push rod, and the push rod moves to push the workpiece 9 to an assembly station of the assembly so as to place the ring piece 8. Besides the vibrating disk and the push rod, a conveyer such as a conveyor belt can be used as a feeding assembly, and the utility model is not described in detail.

Referring to fig. 3-8, the assembly includes a vertical base 3 fixed on the workbench, a liftable base 4 is disposed on the vertical base 3, and the base 4 is slidably connected to the base 4 through a slide rail. The base 4 is driven by the discharging cylinder 31 to ascend and descend, and specifically, the housing of the discharging cylinder 31 is fixed on the vertical base 3, and the piston rod of the discharging cylinder is fixed with the base 4, so that the base 4 is driven to ascend and descend.

The base 4 is provided with sliding blocks capable of translating, each sliding block is provided with a taking and placing assembly, and the taking and placing assemblies are used for clamping the ring piece 8 so as to drive the ring piece 8 to move. Generally, a plurality of picking and placing assemblies are arranged, each picking and placing assembly moves one ring member 8, and the picking and placing efficiency is improved by arranging a plurality of picking and placing assemblies. However, since the ring members 8 moving to the upper material plate 6 are closely adjacent one to one, and the slots of the workpiece 9 have a distance therebetween, the feeding distance of the ring members 8 is inconsistent with the assembling distance of the ring members 8, so that the base 4 is provided with the variable pitch assembly to adjust the distance between each picking and placing assembly, thereby ensuring that the ring members 8 correspond to the slots 91 one to one.

Specifically, the pitch change assembly comprises a limit pull rod 44, a limit pull nail 45 and a shift cylinder 46. Wherein a displacement cylinder 46 is mounted at one end of the base 4. According to the position of the shift cylinder 46, the slide blocks can be divided into a driving slide block 41 close to the shift cylinder 46, a limit slide block 42 far from the shift cylinder 46, and a follower slide block 43 between the driving slide block 41 and the limit cylinder. Whereas if only two slides are provided, there is no follower slide 43. The piston rod of the displacement cylinder 46 is fixed with the driving slider 41, thereby moving the driving slider 41.

One end of the limiting blind rivet 45 is fixedly connected with one sliding block, and the other end of the limiting blind rivet is sleeved in a countersunk hole of the sliding block adjacent to the sliding block, so that the adjacent sliding block can slide along the limiting blind rivet 45. The limit blind rivet 45 is provided with a rivet head 451 in the countersunk hole, and the rivet head 451 can be abutted against the bottom surface of the countersunk hole to limit the distance between two adjacent sliding blocks. For example, the adjacent driving slider 41 and the adjacent following slider 43, and the adjacent limiting slider 42 and the following slider 43 can be connected by a limiting rivet 45. If the follow-up slide block 43 is not provided, the adjacent driving slide block 41 and the limit slide block 42 can also be directly connected through the limit blind rivet 45. If the follow-up sliding blocks 43 are provided in plurality, the adjacent follow-up sliding blocks 43 are also connected through limiting pull nails 45.

Therefore, the driving slide block 41 is pulled to move by the displacement cylinder 46, other slide blocks are driven to move by the limiting pull nails 45, the distance between the slide blocks is changed, and finally, the limiting pull rods 44 with the lengths designed according to the positions of the workpieces 9 ensure that each slide block corresponds to the hole grooves 91 on the workpieces 9 one by one, so that the ring pieces 8 clamped on the picking and placing assembly also have the hole grooves 91 corresponding one by one to carry out picking and placing. On the contrary, the sliding blocks are mutually slid to be close to each other, so that the sliding blocks correspond to the ring pieces 8 on the feeding plate 6 one by one for feeding.
