[0002] In the existing technology, the assembly method of pressing the bearing into the bushing and then installing the retaining ring with calipers is all done manually. Since the retaining ring needs to be manually opened and clamped onto the bearing during installation, the installation is difficult and requires workers to spend a lot of time and energy to complete. At the same time, in terms of product quality control, the manual installation method is not accurate enough and is prone to quality problems such as the bearing not being pressed in properly and the retaining ring not being installed properly. Utility Model Content

[0003] In view of the defects of the existing technology, the technical problem to be solved by this utility model is to provide a semi-automatic device for installing snap rings, which can mechanically perform tasks such as transferring, spreading, and assembling snap rings.

[0004] To achieve the above objectives, this utility model provides the following solution:

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0024] like Figures 1 to 7 The present invention preferably provides a semi-automatic bearing snap ring machine, including a frame 1, a feeding device 2 for loading and intermittently transmitting snap rings on the frame 1, an assembly platform 3 on one side of the frame 1, a column 4 for receiving snap rings and stacking them on the assembly platform 3, an assembly hole 51 for assembling snap rings and bearings, a pushing structure 52 for pushing snap rings to the assembly hole 51, a dropping device 53 for dropping material from the assembly hole 51, a clamping claw component 54 for assisting snap ring expansion to fit into the bearing, and an expansion tooling 55. A stamping upper die 6 and a stamping lower die 7 for pressing snap rings and bearings together are respectively provided above and below the assembly platform 3.

[0025] This technical solution is not limited to semi-automatic use. When operating a single machine, it is used in conjunction with manual semi-automatic operation. When used in conjunction with other machines and equipment for bearing transmission, it can achieve full automation.

[0026] During operation, the feeding device feeds multiple retaining rings into the column in the same configuration. The retaining rings can be stacked vertically on the column with their openings on the same side. Driven by the pushing structure, the retaining ring at the bottom of the column is pushed to the assembly hole. With the activation of the unloading device, the retaining ring falls downwards and fits into the expansion fixture, which is then gripped by the jaw assembly. When the lower and upper stamping dies are activated, the jaw assembly releases the expansion fixture. Because the upper and lower stamping dies simultaneously clamp the expansion fixture, it does not fall downwards. Furthermore, the upper stamping die simultaneously pushes the retaining ring on the expansion fixture downwards, fitting it into the pre-installed bearing inside the lower stamping die. After the upper and lower stamping dies release the expansion fixture, the jaw assembly re-grips it, awaiting the assembly of the next retaining ring.

[0027] The feeding device 2 described in this utility model includes a vibratory feeder 21 located on the front side of the frame 1, and a snap ring feeding groove 22 is provided on the vibratory feeder 21. The vibratory feeder is a common device in the prior art used to convey snap rings in a uniform state. After being conveyed to the snap ring feeding groove, the snap rings output to the column can be fitted into the column and side wing shape with the vibration, until multiple snap rings are fitted onto the column in a stacked manner.

[0028] The assembly platform 3 described in this utility model includes a base frame 31 and an n-shaped platform 32 disposed on top of the base frame 31. A vertical mounting accessory 33 is disposed on the front side of the n-shaped platform 32. A side wing 34 for defining the opening of the retaining spring is provided on the side of the column 4. The side wing 34 is fixed to the side of the vertical mounting accessory 33. The vertical mounting accessory on the n-shaped platform is used to fix the side wing, thereby fixing the column. Since there needs to be a gap at the bottom of the column so that the retaining spring at the bottom can be pushed away by the pusher structure, the column needs to be fixed by the vertical mounting accessory through the side wing.

[0029] The pusher structure 52 described in this utility model includes an inner groove 521 disposed on the upper side of an n-shaped platform 32. A discharge hole 522 communicating with the inner groove 521 is provided at the top of the n-shaped platform 32 below the column 4. A pusher drive 523 is provided on the front side of the top of the base frame 31. A retaining spring pusher 524 is mounted on the movable end of the pusher drive 523 and inserted into the inner groove 521. The pusher drive can be a cylinder or an electric push rod. When activated, the retaining spring pusher inserts into the inner groove, pushing the retaining spring at the bottom of the column backward, causing it to fall into the assembly hole. The discharge hole is the hole through which the retaining spring at the bottom of the column enters the inner groove.

[0030] The blanking device 53 described in this utility model includes a cylinder 531 located at the bottom rear side of the n-shaped platform 32. Two blanking claws 532, which can open and close in parallel, are mounted on the cylinder 531, directly below the assembly hole 51. The cylinder 531 drives the blanking claws to open and close linearly left and right. After the two blanking claws approach each other, the retaining springs falling downwards from the assembly hole will fall onto the two blanking claws until the two blanking claws open, causing the retaining springs to fall downwards and fit onto the expanded part fixture. The function of the blanking device is to prevent the retaining springs falling from the assembly hole from making large movements that could cause assembly problems.

[0031] The clamping jaw component 54 of this utility model includes a second cylinder 541 disposed on the rear side of the top of the base frame 31. Two rotatable and closable grippers 542 are mounted on the second cylinder 541. The expansion tooling 55 is placed inside the grippers 542 and located below the assembly hole 51. The second cylinder can drive the grippers to rotate and open / close, thereby clamping or releasing the expansion tooling. In the clamped state, the upper stamping die and the lower stamping die are in a non-started or starting state. After the upper stamping die and the lower stamping die start and clamp the expansion tooling, the grippers release the expansion tooling and continue to approach and press it through the upper stamping die and the lower stamping die, which will put the retaining ring on the expansion tooling into the bearing.

[0032] The expansion fixture 55 described in this utility model has a cylindrical upper section, a frustum-shaped middle section that is narrower at the top and wider at the bottom, and a frustum-shaped lower section that is wider at the top and narrower at the bottom. The expansion fixture is divided into three sections, and its shape is designed to allow the retaining spring to be opened and then fitted into the bearing.

[0033] The stamping upper die 6 described in this utility model includes an upper die frame 61 disposed on the upper side of the base frame 31. An electric push rod 62 is provided on the top of the upper die frame 61, and an upper die rod 63 is mounted on the downward movable end of the electric push rod 62. The upper die rod 63 can pass through the assembly hole 51 to punch the retaining spring from the expansion tooling 55 into the bearing. By driving the stamping upper die downward through the electric push rod, the upper die rod will be fitted into the upper section of the expansion tooling, causing the retaining spring in the upper section of the expansion tooling to be pressed down. When the upper die rod continues to push and the retaining spring passes through the middle section, the retaining spring will be opened until it enters the lower section.

[0034] The stamping die 7 described in this utility model includes a lower die frame 71 disposed on the lower side of the base frame 31. An electric push rod 72 is disposed at the bottom of the lower die frame 71. A lower die rod 73 is mounted on the upward movable end of the electric push rod 72. A bearing can be installed at the top of the lower die rod 73 and fitted into the expansion tooling 55. The stamping die is started simultaneously with the stamping upper die. The bearing can be manually installed at the top of the lower die rod. When the lower die rod moves upward, the middle hole of the bearing can be fitted into the lower section of the expansion tooling, so that the retaining spring moving downward from the middle section is opened and installed into the bearing. As the retaining spring disengages from the middle section, it automatically retracts and is tightly installed into the bearing. The installation position of the retaining spring is outside the middle bushing inside the bearing.
