Technical Field
[0001] The utility model relates to the technical field of hole ring assembly, in particular to an automatic assembly mechanism for hole retaining rings. Background Art
[0002] There are two common ways to assemble the hole retaining ring in the prior art: one is to manually take the hole retaining ring, put it on the tapered tooling, and press it into the workpiece to be installed with a press-fitting device; the other is to use circlip pliers to assemble, manually hold the circlip pliers, manually clamp the hole retaining ring, reduce the diameter of the hole retaining ring, and then install it in the inner hole of the workpiece. The two assembly methods have the following problems and disadvantages:
[0003] 1) Due to the long-term wear of the corners of the hole retaining ring on the taper tooling, the taper tooling is damaged and a slide groove appears, and iron filings are generated. The iron filings follow the hole retaining ring into the workpiece, seriously affecting the quality and service life of the product.
[0004] 2) Since the hole retaining ring is harder than the workpiece to be installed, the hole retaining ring is easy to scratch the workpiece when it transitions from the tapered tooling to the workpiece.

Figure 3 As shown, the feeding unit 3 includes a motor 31, a motor seat 32, a coupling 33, a positioning mechanism 34, a mounting plate 35, a silo rotating assembly 36 and a rotating silo 37, the rotating silo 37 is connected to the silo rotating assembly 36, the silo rotating assembly 36 is connected to the mounting plate 35, the mounting plate 35 is connected to the base 1, the positioning mechanism 34 is connected to the bottom of the mounting plate 35, the motor seat 32 is arranged below the mounting plate 35, the motor 31 is connected to the motor seat 32, the motor shaft of the motor 31 is connected to the coupling 33, and the coupling 33 is connected to the silo rotating assembly 36.
[0043] The hole retaining ring 8 is manually loaded onto the rotating silo 37. The motor shaft rotates through the coupling 33 to drive the silo rotating assembly 36 to rotate, and then drives the silo to rotate. The positioning mechanism 34 positions the silo, and the lifting mechanism 4 lifts the hole retaining ring 8 to a specified height, and then waits for the material taking mechanism to take the material. The rotating silo 37 is composed of six groups of silos. When one group of silos is emptied, the silo rotates, and the positioning mechanism 37 positions the silo again. The emptied silo can be manually refilled.
[0044] When changing production, the rotary silo 37 is manually removed and replaced with another type of rotary silo.

The rising of the synchronous belt clamping plate 410 drives the support plate to rise along the guide rail, so that the hole retaining ring 8 can be lifted. When a group of silos is emptied, the support plate motor reverses to make the support plate drop to the lowest position. Wait for the rotating silo to rotate the full silo into place, and lift the hole retaining ring again, and this cycle repeats.
[0047] like Figure 7 As shown, the material taking unit 5 includes a bracket 51, a clamping mechanism 52, a lifting cylinder 53 and a transfer mechanism 54. The bracket 51 is fixed on the base 1, the transfer mechanism 54 is connected to the bracket 7, the lifting cylinder 53 is connected to the transfer mechanism 54, and the clamping mechanism 52 is connected to the lifting cylinder 53.

[0048] like Figure 8 , Fig. 9 , Fig.10As shown, the clamping mechanism 52 includes a side mounting plate 5201, a lower mounting plate 5202, an auxiliary clamping claw spring 5203, an upper mounting plate 5204, a limit plate spring shaft 5205, a lifting spring shaft 5206, an auxiliary clamping claw 5207, a circular clamping claw 5208, an upper wedge block 5209, a lower wedge block 5210, a limit plate 5211 and a horizontal spring shaft 5212. The upper mounting plate 5204 is connected to the lifting cylinder 53, and the side mounting plate 5201 is arranged below the upper mounting plate 5204 and is connected to the corresponding upper mounting plate. The lower mounting plate 5202 is connected to the side mounting plate, the upper wedge block 5209 is connected to the lower mounting plate through the lifting spring shaft 5206, the lower wedge block 5210 is connected to the corresponding lower mounting plate 5202 through the horizontal spring shaft 5212, the upper mounting plate 5204 is connected to the limiting plate 5211 through the limiting spring shaft 5205, the limiting plate moves up and down along the guide groove of the lower mounting plate, and a circular clamp 5208 and an auxiliary clamp 5207 are installed at the end of the lower wedge block 5210, and the auxiliary clamp is provided with an auxiliary clamp spring 5203.

The lower wedge block drives the circular clamping claw and the auxiliary clamping claw to open, loosen the hole retaining ring, and clamp it in the workpiece retaining ring groove. When changing production, the hole retaining ring clamping mechanism is replaced, which is easy to operate.
[0049] The circular clamping jaw of the clamping mechanism enters the hole of the hole retaining ring, and the clamping mechanism is pressed down by the pressing mechanism. The circular clamping jaw and the auxiliary clamping jaw clamp the hole retaining ring to reduce the diameter of the hole retaining ring. The limit plate limits the clamping jaw to prevent the clamping jaw from loosening. Before assembly, the limit plate touches the workpiece and opens, the clamping jaw is loosened, and finally the hole retaining ring is placed in the workpiece to be assembled to realize the automatic assembly of the hole retaining ring.
