[0022] like Figures 1-3As shown in the figure, a multi-station snap ring installation device for shafts is used to expand and install a snap ring onto a mounting shaft 3. The multi-station snap ring installation device for shafts includes a fixed base 1, on which a positioning plate 2 is fixedly installed. A plurality of positioning holes 21 are provided on the positioning plate 2, and the positioning holes 21 are used to limit the mounting shaft 3. At the upper end of each positioning hole 21, a placement groove 22 is provided, and the placement groove 22 is used to place the snap ring. In this embodiment, the number of positioning holes 21 is 5, and the 5 positioning holes 21 are equally spaced on the positioning plate 2, so that the multi-station snap ring installation device for shafts can install snap rings on 5 mounting shafts 3 simultaneously, greatly improving the processing and assembly efficiency. In other embodiments, the number of positioning holes 21 can also be any other number.

[0023] A control component and a driving member 4 are provided on the fixed base 1. The driving member 4 is connected to the control component, and the driving member 4 is controlled to work through the control component. A plurality of expanding components are provided at the output end of the driving member 4. The expanding components are arranged in one-to-one correspondence with the placement grooves 22. The expanding components can extend into the corresponding placement grooves 22 and are connected to the snap rings in the corresponding placement grooves 22. The expanding components are used to expand the snap rings in the placement grooves 22. During specific operation, first, the snap rings are respectively placed into the respective placement grooves 22, and the expanding components are connected to the openings of the snap rings. Then, the control component controls the driving member 4 to work, and the driving member 4 drives the expanding components to move, and the expanding components expand the respective snap rings. Then, the mounting shafts 3 are respectively placed into the positioning holes 21 for limitation. At this time, the snap rings have been expanded, and the mounting shafts 3 can pass through the gaps of the snap rings. Then, the control component controls the driving member 4 to reset, driving the expanding components to reset, and the snap rings reset under the action of elastic force, so as to be clamped on the outer side walls of the corresponding mounting shafts 3, completing the installation work of the snap rings.

[0024] The multi-station snap ring installation device for shafts can automatically expand the snap rings and install them onto the mounting shafts 3, reducing manual participation and lowering labor costs. Using the driving member 4 to expand the snap rings can ensure that the expansion force is consistent each time, thereby guaranteeing the qualified rate of processing. Moreover, multiple snap rings can be expanded and installed in one processing, thus improving the processing efficiency.

[0025] In order to limit the installation shaft 3, positioning grooves 11 are respectively provided at positions on the fixed seat 1 corresponding to the positioning holes 21. The positioning grooves 11 are used to limit the installation shaft 3. After the installation shaft 3 passes through the positioning holes 21, it can be inserted into the positioning grooves 11. During processing, after the elastic retaining ring is expanded by the expanding assembly, one end of the installation shaft 3 can be held by hand and passed through the positioning hole 21 and the elastic retaining ring, and then the other end of the installation shaft 3 is inserted into the positioning groove 11. Through the cooperation of the positioning hole 21 and the positioning groove 11, the installation shaft 3 can be limited on the fixed seat 1, so that the elastic retaining ring can be smoothly and stably clamped on the outer side of the installation shaft 3, improving the stability of processing.

[0026] In this embodiment, the driving member 4 is a clamping jaw cylinder. An installation platform 5 is fixedly installed on the fixed seat 1, and the driving member 4 is fixedly installed on the installation platform 5. Through the driving member 4, the expanding assembly can be driven to open or reset, so as to realize the functions of expanding and releasing the elastic retaining ring. In other embodiments, the driving member 4 can also be other driving devices, such as: a motor lead screw structure, etc.

[0027] Specifically, the expanding assembly includes a plurality of expanding pins 6. Two guide rods 7 are installed on the output end of the driving member 4, and the two guide rods 7 are arranged in parallel. The driving member 4 can drive the two guide rods 7 to move in opposite directions. Each guide rod 7 is provided with an expanding pin 6 at a position corresponding to the placement groove 22, so that each placement groove 22 is provided with two expanding pins 6. The expanding pins 6 can be inserted into the openings of the elastic retaining ring. During the specific processing process, after the elastic retaining ring is placed in the placement groove 22, the expanding pins 6 in each placement groove 22 are respectively inserted into the openings on the elastic retaining ring. When expanding the elastic retaining ring, the driving member 4 drives the two guide rods 7 to move in opposite directions, and the guide rods 7 drive the expanding pins 6 to move together, so that the two expanding pins 6 in the same placement groove 22 move in a direction away from each other, thereby expanding the elastic retaining ring. When the elastic retaining ring is clamped onto the installation shaft 3, the driving member 4 drives the two guide rods 7 to reset, driving the two expanding pins 6 in the same placement groove 22 to move in a direction close to each other, so that the elastic retaining ring closes and is clamped on the outer side wall of the installation shaft 3.

[0028] In order to limit and guide the movement direction of the guide rod 7, two guide blocks 8 are installed on the positioning plate 2. The two ends of the two guide rods 7 respectively pass through the guide blocks 8 and are slidably connected to the guide blocks 8. When the driving member 4 works, it drives the guide rod 7 to slide on the guide block 8; through the cooperation of the guide block 8 and the guide rod 7, the movement direction of the guide rod 7 is further limited and guided, so as to ensure that the guide rod 7 can drive the expanding pins 6 to approach or move away from each other, ensuring the stability of processing.

[0029] The control component includes a solenoid valve 9, a pressure regulator 10, and a power control board 12 fixedly installed on the fixed seat 1. The power control board 12 is electrically connected to the pressure regulator 10 and the solenoid valve 9 respectively, and the power control board 12 is externally connected to a power source, thereby facilitating the control of the multi-station shaft snap ring installation device. The solenoid valve 9 is connected to the pressure regulator 10 and the driving member 4 respectively, and the pressure regulator 10 is externally connected to a gas source. The solenoid valve 9 is used to control the operation of the driving member 4, and the pressure regulator 10 is used to adjust the driving force of the driving member 4, thereby ensuring the stability of processing. During specific operation, the solenoid valve 9 is controlled to operate through the power control board 12, so that the driving member 4 is ventilated or cut off, realizing the function of controlling the operation of the driving member 4; by adjusting the pressure regulator 10, the driving force of the driving member 4 can be adjusted in time, so as to ensure that the expanding pin 6 can expand the snap ring to a suitable size.

[0030] A start switch 13 and an indicator light 14 are provided on the power control board 12. The start switch 13 is used to control the operation or shutdown of the multi-station shaft snap ring installation device; the indicator light 14 is used to indicate whether the multi-station shaft snap ring installation device is powered on, so that the operator can check in time, improving the interactivity.

[0031] Working principle:

[0032] Before processing, the appropriate output air pressure is adjusted by operating the pressure regulator 10 to ensure that the driving member 4 can provide appropriate driving force.

[0033] During processing, the snap rings are respectively placed into the respective placement grooves 22, and the corresponding expanding pins 6 in the respective placement grooves 22 are inserted into the openings of the snap rings, so that the snap rings are firmly inserted and connected with the expanding pins 6. Then, by pressing the start switch 13, the solenoid valve 9 is controlled to operate through the power control board 12, so that the driving member 4 intakes air and operates. The driving member 4 drives the two guide rods 7 to move in opposite directions, and the guide rods 7 drive the expanding pins 6 to move together, so that the two expanding pins 6 in the same placement groove 22 move away from each other, and then the snap ring in the placement groove 22 is expanded to a suitable size. Then the installation shaft 3 is passed through the snap ring and the positioning hole 21, and one end of the installation shaft 3 is inserted into the positioning groove 11 for limit fixation; then the start switch 13 is released, and the power control board 12 will control the solenoid valve 9 to close, and the driving member 4 automatically resets to drive the two guide rods 7 to reset, driving the expanding pins 6 to move closer to each other, and the snap ring resets under the action of elastic force, so as to be clamped on the outer side wall of the corresponding installation shaft 3, completing the installation work of the snap ring.

The scope of the present invention includes but is not limited to this specific implementation manner. All equivalent changes made in accordance with the present invention are within the protection scope of the present invention.
