In one embodiment of the present invention, as shown in fig. 1 and 2, the tooling device may include a bearing frame 1, a first driving mechanism 61 and a slide rail 60. The side of the bearing frame 1 is provided with a slide rail 60, and the prepressing mechanism 3 is connected with the bearing frame 1 through the slide rail 60. The first driving mechanism 61 is fixedly connected to the bearing frame 1 and located above the pre-pressing mechanism 3, and the first telescopic shaft 610 of the first driving mechanism 61 is connected to the pre-pressing mechanism 3 to drive the pre-pressing mechanism 3 to slide up and down on the slide rail 60.

The bearing frame 1 that this tool equipment included provides the support for this tool equipment. The side of the bearing frame 1 can be provided with a slide rail 60. The prepressing mechanism 3 may include a loading plate 31, a fixing frame 32, and a prepressing slider 33. A prepressing slider 33 may be provided between the prepressing mechanism 3 and the slide rail 60. The carrier plate 31 may be arranged perpendicular to the pre-pressing plane 30 for carrying the pre-pressing means 3. A holder 32 may be arranged between the pre-pressing plane 30 and the carrier plate 31 to hold the pre-pressing plane 30 and the carrier plate 31 in place. The loading plate 31 can be connected with the sliding rail 60 through the pre-pressing sliding block 33, so that the pre-pressing mechanism 3 can be connected with the sliding rail 60 through the pre-pressing sliding block 33, and the pre-pressing mechanism 3 can slide along the sliding rail 60 without deviation. The first driving mechanism 61 is fixedly connected to the bearing frame 1 and is located above the pre-pressing mechanism 3. The first telescopic shaft 610 of the first drive mechanism 61 is connected to the prepressing mechanism 3. The first driving mechanism 61 can control the first telescopic shaft 610 to slide up and down, so the first driving mechanism 61 can control the pre-pressing mechanism 3 to slide up and down on the slide rail 60 by controlling the first telescopic shaft 610. When the circlip prepressing operation is needed, the first driving mechanism 61 can control the prepressing mechanism 3 to press down on the slide rail 60 for a certain distance so as to complete the prepressing of the circlip.

In one embodiment of the present invention, as shown in fig. 1 and 2, a stopper 62 may be disposed on the sliding rail 60, and the stopper 62 may be disposed near the bottom of the sliding rail 60. A limiting column 63 matched with the limiting block 62 for limiting can be arranged on one side of the prepressing mechanism 3 close to the bearing frame 1.

When the prepressing mechanism 3 slides down along the slide rail 60, the limiting block 62 disposed near the bottom of the slide rail 60 may block the prepressing mechanism 3 to limit further movement of the prepressing mechanism 3. When the clamp spring needs to be pressed down in advance, the prepressing mechanism 3 slides along the slide rail 60, the clamp spring is pressed into a product while the prepressing mechanism slides down, and when the limiting block 62 arranged near the bottom of the slide rail 60 blocks the sliding down of the prepressing mechanism 3, the clamp spring is also pressed into the product by the prepressing mechanism 3 to a certain depth. The limiting column 63 can penetrate through the limiting block 62 and is connected to the bottom of the loading plate 31, the limiting column 63 can be connected to the pre-pressing mechanism 3, and a protrusion larger than a hole penetrating through the limiting block 62 is formed at the bottom of the limiting column 63. The stopper pin 63 does not participate in the stopper when the prepressing mechanism 3 is pressed down. When the prepressing mechanism 3 is pulled up, because the protrusion at the bottom of the limiting column 63 is larger than the hole through which the limiting block 62 penetrates, the protrusion at the bottom of the limiting column 63 cannot move upwards any more when reaching the bottom of the limiting block 62, and the prepressing mechanism 3 connected with the limiting column 63 is also limited from moving upwards, so that the limiting column 63 can limit the displacement of the prepressing mechanism 3 in the vertical direction.

In one embodiment of the present invention, as shown in fig. 1, 2 and 3, the tooling assembly includes a second drive mechanism 64. The second driving mechanism 64 is disposed on the pre-pressing mechanism 3, and a second telescopic shaft 640 of the second driving mechanism is connected to the tapered cylinder 40 to drive the tapered cylinder 40 to move in the vertical direction.

The pre-pressing plane 30 may include a carrier 41, and the second driving mechanism 64 is disposed on the carrier 41. The tapered cylinder 40 may be disposed at the bottom of the carrier 41, and the second telescopic shaft 640 of the second driving mechanism 64 may be connected to the tapered cylinder 40. After the pre-pressing plane 30 is pressed down in advance to press the snap spring into the product, the tapered cylinder 40 is further pressed down under the driving of the second telescopic shaft 640 of the second driving mechanism 64 to press the snap spring into the product.

In one embodiment of the present invention, the second telescopic shaft 640 moves the tapered cylinder 40 up and down. The diameter of the tapered cylinder 40 is the same as the inner diameter of the product, and after the pre-pressing plane 30 is pressed down in advance, the tapered cylinder 40 can be further pressed down to press the snap spring into the product. But without the presence of the limiting mechanism, the pressing depth of the conical cylinder 40 is not easy to control. Therefore, the limit stopper 65 may be provided on the second telescopic shaft 640 of the second drive mechanism 64. The limit stopper 65 may limit the displacement of the tapered cylinder 40 in the vertical direction. After the preliminary pressing down of the pre-pressing plane 30, the tapered cylinder 40 is further pressed down. After the toper cylinder 40 pushes down the certain distance, set up limit stop 65 on second telescopic shaft 640 and the top contact of pre-compaction plane 30, this second telescopic shaft 640 can't continue to push down, the toper cylinder 40 of being connected with second telescopic shaft 640 also can't continue to push down, then the jump ring that is driven by toper cylinder 40 also can't continue to push down after being impressed the product, consequently the jump ring is fixed on the certain degree of depth of the inside of product, thereby accomplished and pressed into the controllable work of the inside degree of depth of product to the jump ring.

In one embodiment of the utility model, the securing mechanism 2 comprises a jaw 20 for gripping a product. A third drive mechanism 21 is connected to the jaws 20 for actuation to open or lock the jaws 20. A sensor 22 may be provided adjacent the jaws 20 for acquiring a position signal of the product to determine whether the product is placed in the jaws 20. The fixing mechanism may further include a support plate 23. The clamping jaws 20, the third drive mechanism 21 and the sensor 22 may all be arranged on a support plate 23. The bottom of the supporting plate 23 can be connected with the feeding mechanism 5 so that the supporting plate 23 is moved by the feeding mechanism 5. A support bracket 24 may also be provided on the support plate to support the sensor 22 and the jaws 20.

After the fixing mechanism 2 is driven to a designated position by the feeding mechanism 5, a worker can put a product into the middle of the clamping jaw 20, and after the sensor 22 near the clamping jaw 20 determines that the product is put into the middle of the clamping jaw 20, the clamping jaw 20 is driven by the third driving mechanism 21 to lock the product. The feeding mechanism 5 can then drive the fixing mechanism 2 to return to the initial position to complete the installation of the snap spring.

In one embodiment of the utility model, the tooling device includes a base plate 66 for carrying the feed mechanism 5. The feeding mechanism 5 comprises a feeding seat 50, and the feeding seat 50 is connected with the fixing mechanism 2. The feeding slide rail 52 is arranged on the bottom plate 66 and connected with the feeding seat 50 through the slide block 51. The fourth driving mechanism 53 is fixed on the bottom plate 66, and the fourth telescopic shaft 530 of the fourth driving mechanism 53 is connected with the feeding seat 50 to drive the feeding seat 50 to slide on the feeding slide rail 52.

The feeding seat 50 can be connected with the supporting plate 23 of the fixing mechanism 2 to drive the supporting plate 23 to move. Since the feeding base 50 is driven by the fourth driving mechanism 53 to move on the feeding slide rail 52, the feeding base 50 is not easy to shift, and a fast and stable feeding operation can be realized.

In one embodiment of the present invention, a limit ejector 54 may be further provided on the feeding base 50. The limiting mandrils 54 are respectively arranged at two sides of one end of the feeding seat close to the bearing frame 1. The limit ejector rod 54 is connected with the feeding seat 50 and slides along with the feeding seat 50 in the horizontal direction. A protrusion may be provided at the end of the position-limiting push rod 54 to cooperate with a protrusion provided on the bottom plate 66 for position limitation. When the feeding seat 50 is driven by the fourth driving mechanism 53 to move in a direction away from the support shaft 1, the limit ejector rod 54 connected with the feeding seat 50 is driven to move together, after a protrusion at the tail part of the limit ejector rod 54 contacts with a protrusion arranged on the bottom plate 66 for limiting, the limit ejector rod 54 cannot move any more, and the feeding seat 50 connected with the limit ejector rod 54 cannot move any more, so that the horizontal displacement of the feeding seat 50 on the feeding slide rail 52 is completed.
