Description

Technical Field

[0001] This invention relates to the field of mechanical automation technology, and in particular to a shaft retaining ring mounting device and its mounting method. Background Technology

[0002] A retaining ring is a fastener used to prevent axial movement of parts on a shaft or in a hole. It can withstand severe vibration and impact loads and is widely used in various mechanical products in daily life. The inner diameter of the retaining ring is slightly smaller than the diameter of the shaft to which it is installed. The retaining ring is fitted into the shaft groove or hole groove of the shaft in the machine or equipment. When installing a retaining ring, the operator needs to use snap ring pliers to insert the jaws into the pliers hole of the retaining ring to expand it before it can be placed into the shaft groove or hole groove of the shaft.

[0003] However, the method of manual assembly by operators has the following drawbacks:

[0004] 1. It consumes a lot of human resources and increases labor costs.

[0005] 2. In precision assemblies such as those for automotive motor shafts, manual assembly methods cannot meet the assembly requirements.

[0006] 3. When manually assembling the shaft retaining ring, if the shaft retaining ring is opened too wide, the deformation will exceed the elastic limit of the shaft retaining ring, which can easily lead to the failure of the shaft retaining ring.

Opening the shaft retaining ring before installation on the shaft and tightening it during installation replaces the manual assembly method of manually inserting pliers into the retaining ring's opening to expand it, resulting in a high degree of automation. By providing a cavity between the two rotating parts for the shaft to be installed, the shaft retaining ring can be aligned with the mounting groove of the shaft, facilitating the installation or removal of the shaft retaining ring from the shaft.

Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0056] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0057] like Figures 1 to 3 As shown, this embodiment provides a shaft retaining ring mounting device, including a rotating assembly 1 and a driving assembly 2. The rotating assembly 1 includes two rotating parts 11 that can rotate around the axis of the shaft to be mounted. A cavity is provided between the two rotating parts 11 for the shaft to be mounted to be inserted. The two ends of the opening of the shaft retaining ring 100 are detachably connected to the two rotating parts 11 respectively. The shaft retaining ring 100, the cavity, and the shaft to be mounted are coaxially arranged. The driving assembly 2 is connected to the rotating parts 11 to drive the two rotating parts 11 to rotate around the axis of the shaft to be mounted. The two ends of the opening of the shaft retaining ring 100 can move towards or away from each other to open or close the shaft retaining ring 100, so as to install or remove the shaft retaining ring 100 in the mounting groove of the shaft to be mounted.

[0058] The shaft retaining ring mounting device provided in this embodiment, by providing a cavity between two rotating parts 11 for inserting the shaft to be mounted, can align the shaft retaining ring 100 with the mounting groove of the shaft to be mounted. The drive assembly 2 is connected to the rotating parts 11 to drive the two rotating parts 11 to rotate around the axis of the shaft to be mounted. This allows the shaft retaining ring 100 to open before being inserted into the cavity on the shaft to be mounted, and to tighten after the shaft is inserted into the cavity and the mounting groove corresponds to the shaft retaining ring 100. This replaces the manual assembly method where an operator manually inserts pliers into the pliers hole of the shaft retaining ring 100 to expand it, resulting in a high degree of automation. This shaft retaining ring mounting device achieves automatic assembly of the shaft retaining ring 100 and the shaft to be mounted, freeing up labor to reduce labor costs, preventing the shaft retaining ring 100 from failing due to manual assembly, and ensuring higher work efficiency to adapt to a faster production pace.

[0059] In this embodiment, as Figure 1 As shown, the shaft retaining ring 100 has clamp holes at both ends of its opening, and the rotating part 11 has a tension pin 1111 that can pass through the clamp holes. The shaft retaining ring 100 is detachably connected to the rotating part 11 only at the clamp holes. The rest of the shaft retaining ring 100 is separated from the rotating part 11. When the two ends of the shaft retaining ring 100 at its opening move towards or away from each other, the relative position of the shaft retaining ring 100 and the rotating part 11 moves slightly, but this does not affect the insertion of the shaft being installed into the cavity between the two rotating parts 11.

[0060] Specifically, the rotating part 11 is provided with a mounting groove and a telescopic component. The clamp hole, the mounting groove, and the tension spring pin 1111 are coaxially arranged. One end of the telescopic component is connected to a drive motor that can drive the telescopic component to extend and retract, and the other end of the telescopic component is connected to the tension spring pin 1111, allowing the tension spring pin 1111 to pass through the mounting groove and the clamp hole. When the tension spring pin 1111 is in the extended state, the two ends of the opening of the shaft retaining ring 100 can be connected to the two rotating parts 11 respectively, so that when the rotating part 11 rotates, it can drive the two ends of the shaft retaining ring 100 to rotate closer to or further away from each other, realizing the opening or tightening of the shaft retaining ring 100. When the tension spring pin 1111 is in the retracted state, the shaft retaining ring 100 can be removed from the rotating part 11.

[0061] In this embodiment, the rotating part 11 is rotatably connected to the support assembly 3. Specifically, each rotating part 11 includes a rotating sleeve 111 and a bushing 112. The bushing 112 is rotatably connected to the support assembly 3, and the rotating sleeve 111 and the bushing 112 are detachably connected. Both ends of the opening of the shaft retaining ring 100 are detachably connected to the rotating sleeve 111. The rotating sleeve 111 can be set according to the size of the shaft retaining ring 100. Through the detachable connection between the rotating sleeve 111 and the bushing 112, it is convenient to replace the rotating sleeve 111 of different sizes to meet the installation connection of the shaft retaining ring 100 of different sizes.

[0062] Specifically, the rotating sleeve 111 and the bushing 112 are respectively provided with positioning holes and screw holes. The positioning pin positions the two positioning holes, and the two screw holes are connected by screws to achieve a detachable connection between the two.

[0063] Furthermore, such as Figure 2 As shown, the cavity wall between the two rotating parts 11 has an opening for the two rotating parts 11 to rotate in a direction that allows them to move closer to or further away from each other. The two rotating parts 11 can adjust their rotation angle by rotating within the opening of the cavity, thereby opening or closing the shaft retaining ring 100. Specifically, both the rotating sleeve 111 and the shaft sleeve 112 are semi-cylindrical structures. A first cavity capable of forming a cylindrical shape is provided between the two opposing rotating sleeves 111, facilitating the insertion of the mounted shaft into the first cavity. A second cavity is provided between the two opposing shaft sleeves 112. The first cavity and the second cavity are coaxially arranged, and both cavity walls have openings that extend in the same direction.

[0064] In this embodiment, as Figure 3 As shown, a rotating shaft 1121 is provided in the second cavity. The rotating shaft 1121 is coaxially arranged with the shaft to be installed and is fixedly connected to the support assembly 3. The bushing 112 is rotatably connected to the rotating shaft 1121 through a bearing. The inner ring of the bearing is fixedly connected to the rotating shaft 1121, and the outer ring of the bearing is fixedly connected to the bushing 112. Specifically, a deep groove ball bearing is used. In other embodiments, a roller bearing may also be used, which is not specifically limited here.

[0065] like Figure 1 As shown, the driving assembly 2 provided in this embodiment includes a first driving member 21, a push rod 22, and a moving member 23. The first driving member 21 is disposed on the support assembly 3. One end of the push rod 22 is connected to the output end of the first driving member 21. One end of the moving member 23 is provided with a first waist-shaped hole 231, and the other end of the push rod 22 is slidably disposed in the first waist-shaped hole 231. The push rod 22 can be pressed against the inner wall of the first waist-shaped hole 231, so that the moving member 23 can be translated in a direction closer to or away from the rotating part 11. Specifically, the moving direction of the push rod 22 is vertical.

[0066] like Figure 2 As shown, the other end of the moving part 23 is provided with a second waist-shaped hole 232. The rotating part 11 provided in this embodiment is provided with a slide rod. Specifically, each bushing 112 is fixedly connected with a slide rod. The slide rod is provided near the opening of the second cavity of the bushing 112. The slide rod is slidably disposed in the second waist-shaped hole 232. The slide rod can be pressed against the inner wall of the second waist-shaped hole 232 so that the rotating part 11 rotates around the axis of the mounted shaft as the moving part 23 translates.

[0067] With the above-mentioned structural arrangement of the drive component 2, the push rod 22 is connected to the moving part 23 through the first waist-shaped hole 231, which can drive the moving part 23 to translate. The moving part 23 is connected to the rotating part 11 through the second waist-shaped hole 232, which can drive the rotating part 11 to rotate. By setting the moving part 23 to change the driving direction, the purpose of opening or tightening the shaft retaining ring 100 can be achieved, saving the driving space in the axial direction of the installed shaft.

[0068] Specifically, the first driving component 21 is a cylinder, and the piston rod of the cylinder is connected to the push rod 22 through a floating joint.

[0069] Furthermore, such as Figure 2 As shown, the movable component 23 consists of two plates that are vertically arranged and fixedly connected. The intersection line of the two plates extends radially along the shaft to be installed, and the cross-section of the first plate is parallel to that of the shaft to be installed. A first oblong hole 231 passes through the second plate, and the length direction of the first oblong hole 231 forms an acute angle with the moving direction of the push rod 22. A second oblong hole 232 passes through the first plate, and two sliding rods are respectively slidably disposed in the two second oblong holes 232. The two second oblong holes 232 are symmetrically arranged in a figure-eight shape with respect to the intersection line of the two plates. When the two sliding rods slide simultaneously to the ends where the two second oblong holes 232 are close to each other, the two bushings 112 drive the two rotating sleeves 111 to rotate and move closer to each other, and the shaft retaining ring 100 connected to the rotating sleeve 111 can be tightened. Similarly, when the two sliding rods slide simultaneously to the ends where the two second oblong holes 232 are far apart, the shaft retaining ring 100 can be opened.

[0070] like Figure 1 As shown, the drive assembly 2 provided in this embodiment also includes a guide sleeve 26, which is fixedly connected to the support assembly 3. The moving part 23 is slidably disposed in the guide sleeve 26. The guide sleeve 26 enables the moving part 23 to always move in the radial direction of the shaft being installed, ensuring the correctness of the sliding direction and improving the sliding stability.

[0071] Specifically, the other end of the push rod 22 is provided with a rotating rod, which is slidably disposed within the first oblong hole 231 via a deep groove ball bearing. The inner ring of the deep groove ball bearing is connected to the rotating rod, and the outer ring abuts against the inner wall of the first oblong hole 231. The sliding rod of the bushing 112 is slidably disposed within the second oblong hole 232 via a deep groove ball bearing. The inner ring of the deep groove ball bearing is connected to the sliding rod, and the outer ring of the deep groove ball bearing abuts against the inner wall of the second oblong hole 232. In other embodiments, the deep groove ball bearing can also be replaced with a roller bearing, which is not specifically limited here.

[0072] In order to provide movement space within the bushing 112 when the moving part 23 translates in the radial direction toward the mounted shaft, the bearings on the bushing 112 provided in this embodiment are symmetrically arranged at both ends of the rotating shaft 1121 relative to the moving part 23, thereby forming a clearance space in the middle of the bushing 112 to allow the moving part 23 to move smoothly, and at the same time enhancing the stability of the rotational connection between the bushing 112 and the rotating shaft 1121.

[0073] In this embodiment, the moving member 23 has a first state in which the two rotating parts 11 are driven away from each other to open the shaft retaining ring 100, and a second state in which the two rotating parts 11 are driven closer to each other to tighten the shaft retaining ring 100.

[0074] In order to limit the movement of the movable part 23 in two states, such as Figure 1 As shown, the driving assembly 2 provided in this embodiment also includes a limiting member 24, which includes a baffle 241, a limiting rod 242, and a limiting screw 243. The baffle 241 is fixedly connected to the support assembly 3. The limiting rod 242 is fixed to the moving member 23 and slidably connected to the baffle 241. One end of the limiting rod 242 away from the moving member 23 passes through the baffle 241 and is provided with a limiting head, so that when the moving member 23 reaches the first state, the limiting head can abut against the baffle 241. The limiting screw 243 passes through one end of the baffle 241 and is positioned between the baffle 241 and the moving member 23, so that when the moving member 23 reaches the second state, the moving member 23 can abut against the limiting screw 243.

[0075] Specifically, baffle 241 is fixedly connected to guide sleeve 26, and guide sleeve 26 is fixedly connected to support assembly 3. Limit screw 243 is threadedly connected to baffle 241, and the distance between limit screw 243 and moving part 23 can be adjusted to adjust the limit distance.

[0076] When installing shaft retaining rings 100 of different sizes, the travel of the moving part 23 will vary. By setting the limiting part 24 to adjust the limiting distance, it can adapt to the opening and closing requirements of shaft retaining rings 100 of different sizes. This can prevent the shaft retaining ring 100 from opening too wide and causing damage, or prevent the shaft retaining ring 100 from tightening too narrowly and causing collision and friction between the shaft retaining ring 100 and the installed shaft, which can easily lead to cost losses for both the shaft retaining ring 100 and the installed shaft.

[0077] like Figure 1 As shown, the shaft retaining ring mounting device provided in this embodiment also includes a support assembly 3, which includes a first support plate 31, a second support plate 32, and a support column 33. Specifically, one end of the support column 33 is connected to the first support plate 31, and the other end of the support column 33 is connected to the second support plate 32. The first support plate 31 is connected to the first driving member 21, and the second support plate 32 is fixedly connected to the guide sleeve 26. The second support plate 32 has a through hole, through which the push rod 22 passes and is slidably connected to the first waist-shaped hole 231. The support assembly 3 also includes a connecting plate fixedly connected to the second support plate 32. The connecting plate has a positioning hole coaxially arranged with the shaft to be installed, and the rotating shaft 1121 is positioned and installed in the positioning hole of the connecting plate.

[0078] By providing the support column 33, space is provided for the connection between the first drive member 21 and the push rod 22. By providing the support assembly 3, support is provided for the rotating assembly 1, which helps to improve the stability of the shaft retaining ring mounting device.

[0079] In this embodiment, the shaft retaining ring mounting device further includes a second driving member 25. The output end of the second driving member 25 is connected to the support assembly 3, so as to drive the rotating part 11 to move closer to or away from the shaft being mounted along the axial direction of the shaft being mounted via the support assembly 3. Specifically, the output end of the second driving member 25 is connected to the first support plate 31. The second driving member 25 is a cylinder, and the piston rod of the cylinder is connected to the first support plate 31 through a floating joint.

[0080] The shaft retaining ring mounting device provided in this embodiment also includes a guide assembly 4. The guide assembly 4 includes a first mounting plate 41, a first guide post 42, and a second mounting plate 43. The first mounting plate 41 is connected to the support assembly 3, specifically, the first mounting plate 41 is connected to the first support plate 31. One end of the first guide post 42 is fixedly connected to the first mounting plate 41, and the second mounting plate 43 is used for fixed connection with adjacent equipment. The other end of the first guide post 42 passes through the second mounting plate 43. A second driving member 25 is disposed on the second mounting plate 43, and the output end of the second driving member 25 passes through the second mounting plate 43 and is connected to the first mounting plate 41. The axial direction of the first guide post 42 is parallel to the axial direction of the shaft being mounted.

[0081] By setting the first guide post 42 of the guide component 4, the first mounting plate 41 connected to the support component 3 can be driven by the first drive member 21 to further drive the rotating part 11 to move towards the direction of the shaft to be installed. This ensures that the cavity of the rotating part 11 is always coaxial with the shaft to be installed during the movement, so as to ensure that the shaft to be installed can be inserted into the cavity.

[0082] Furthermore, a limiting plate 44 is provided at the other end of the first guide post 42, which passes through the second mounting plate 43. A limiting block 45 is provided on the side of the limiting plate 44 facing the second mounting plate 43, and the limiting block 45 selectively abuts against the second mounting plate 43. Specifically, the limiting block 45 is provided with a screw that is screwed to the limiting plate 44. The distance between the limiting block 45 and the second mounting plate 43 is adjusted by screwing the screw, so as to adjust the distance by which the rotating part 11 driven by the second driving member 25 through the support assembly 3 moves closer to the mounting shaft.

[0083] In this embodiment, the support component 3 is slidably connected to the first mounting plate 41. A connecting block 46 is fixedly connected to the first mounting plate 41, and a screw is screwed onto the connecting block 46. The support component 3 is provided with a plurality of screw holes that can be threadedly connected to the screws, and the plurality of screw holes are distributed along the sliding direction of the support component 3.

[0084] Specifically, the first support plate 31 is slidably connected to the first mounting plate 41, and the first support plate 31 is provided with a plurality of screw holes that can be threaded with screws. By screwing a screw into one of the screw holes, the relative position of the first support plate 31 and the first mounting plate 41 can be adjusted so as to make the cavity of the rotating part 11 and the mounted shaft coaxial.

[0085] The second mounting plate 43 provided in this embodiment is fixedly connected to adjacent equipment. Specifically, the second mounting plate 43 is fixedly connected to the machine tool.

[0086] In other embodiments, the second mounting plate 43 may not be fixedly connected to the adjacent device. Further, the guide assembly 4 also includes a third mounting plate, a second guide post, and a third drive member. The third mounting plate is fixedly connected to the adjacent device, the second guide post is fixed to the second mounting plate 43 and slidably connected to the third mounting plate, and the output end of the third drive member is connected to the second mounting plate 43. With the above structural arrangement, selective driving between the second drive member 25 and the third drive member is possible, improving the practicality of the shaft retaining ring mounting device.

[0087] This embodiment also provides a method for installing a shaft retaining ring, which includes the following steps:

[0088] First, connect the two ends of the opening of the shaft retaining ring 100 to the two rotating parts 11 respectively. Drive the rotating parts 11 to rotate by the drive assembly 2, and move the two ends of the opening of the shaft retaining ring 100 away from each other to open the shaft retaining ring 100.

[0089] Specifically, when the tension pins 1111 are in the extended state, the drive assembly 2 drives the rotating part 11 to rotate until the two tension pins 1111 are coaxial with the two clamp holes of the shaft retaining ring 100 in the stationary state. The clamp holes of the shaft retaining ring 100 are then manually passed through the tension pins 1111 to connect the two ends of the opening of the shaft retaining ring 100 to the two rotating parts 11 respectively. Then, the drive assembly 2 drives the two rotating parts 11 to rotate in a direction away from each other at the cavity opening to open the shaft retaining ring 100.

[0090] By following the above steps, the shaft retaining ring 100 can be in an open state before being installed on the shaft to be installed, which helps to fit the shaft retaining ring 100 onto the shaft to be installed, making installation easier.

[0091] Then, the axis of the shaft to be installed is collinear with the axis of the cavity, and one end of the shaft to be installed is inserted into the cavity. The shaft retaining ring 100 is aligned with the mounting groove of the shaft to be installed.

[0092] Specifically, the position of the shaft being installed is fixed. By screwing the screws on the connecting block 46 into the screw holes at different positions on the first support plate 31, the relative position of the connecting block 46 and the first support plate 31 can be adjusted, thereby adjusting the relative position of the cavity and the shaft being installed so that the axis of the shaft being installed and the axis of the cavity are collinear.

[0093] Specifically, after the axis of the shaft to be installed is collinear with the axis of the cavity, the second drive member 25 drives the support assembly 3. The support assembly 3 drives the cavity of the rotating part 11 to approach the shaft to be installed, so that one end of the shaft to be installed is inserted into the cavity. The second drive member 25 stops driving after the shaft retaining ring 100 is aligned with the mounting groove of the shaft to be installed.

[0094] The above steps help to insert the shaft retaining ring 100 into the shaft to be installed and align it with the mounting groove of the shaft, which facilitates installation.

[0095] Finally, the rotating part 11 is driven to rotate in the opposite direction by the drive assembly 2, so that the two ends of the shaft retaining ring 100 at the opening are moved closer to each other to tighten the shaft retaining ring 100, and the shaft retaining ring 100 is installed in the mounting groove on the shaft to be installed. The shaft retaining ring 100 and the rotating part 11 are then removed to complete the installation.

[0096] Specifically, the drive assembly 2 drives the two rotating parts 11 to rotate towards each other at the cavity opening to tighten the shaft retaining ring 100. Then, the tension spring pin 1111 is retracted, and the shaft retaining ring 100 and the rotating parts 11 are disassembled. Then, the support assembly 3 is driven by the second drive member 25, and the support assembly 3 drives the cavity of the rotating part 11 away from the shaft to be installed, thus completing the installation.

[0097] Through the above steps, the shaft retaining ring 100 can be installed on the shaft to be installed and removed from the mounting device. This method of installing the shaft retaining ring achieves automatic assembly of the shaft retaining ring 100 and the shaft to be installed. It has a high degree of automation and high assembly accuracy, is easy to use, can free up labor to reduce labor costs, prevent the problem of the shaft retaining ring 100 failing due to manual assembly, and at the same time can ensure higher operating efficiency and adapt to a faster production pace.

[0098] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
