Description

Technical Field

[0001] This application relates to the technical field of bearing assembly tools, and particularly to a flexible bearing press-fitting tool for a harmonic reducer. Background Art

[0002] In the production process of harmonic reducers, the precise assembly of the wave generator and the flexible bearing is a key technical link. Since the wave generator is not a circular structure but an elliptical one, while the flexible bearing is circular, during assembly, the flexible bearing needs to be deformed before it can be assembled onto the wave generator.

[0003] In traditional assembly processes, most are installed manually by hand and then combined with lathe turning and pressing for installation. This method has low assembly efficiency due to the lack of effective guidance and is prone to damaging the bearing surface. At the same time, due to the thickness difference between the wave generator and the flexible bearing during lathe turning and pressing, problems such as pressing position deviation caused by over-pressing are also likely to occur. Summary of the Invention

[0004] To solve the above problems, this application provides a flexible bearing press-fitting tool for a harmonic reducer, which has the advantages of improving assembly efficiency and reducing press-fitting deviation.

[0005] A flexible bearing press-fitting tool for a harmonic reducer provided by this application adopts the following technical solutions: A flexible bearing press-fitting tool for a harmonic reducer includes a base for placing the wave generator, an elliptical mandrel for aligning and installing the wave generator, and an assembly sleeve for press-fitting the flexible bearing. The elliptical mandrel adopts a gradually changing elliptical cone structure with a smaller upper part and a larger lower part. The shape of the bottom end face of the elliptical mandrel is the same as that of the wave generator and its size is equal to or larger than the wave generator. A limiting step for limiting the flexible bearing is provided on the base. The assembly sleeve is sleeved on the elliptical mandrel, and the shape and size of the cross-section of the inner hole of the assembly sleeve are the same as those of the bottom end face of the elliptical mandrel.

[0006] By adopting the above technical solutions, during assembly, the wave generator and the elliptical mandrel are adjusted circumferentially to complete alignment, and then their relative positions are fixed through installation. Then the elliptical mandrel and the wave generator are placed on the base together, and the flexible bearing is sleeved from the upper end of the elliptical mandrel. Finally, by pressing down the assembly sleeve, the assembly sleeve is sleeved onto the elliptical mandrel. At this time, during the downward pressing process of the assembly sleeve, it will drive the flexible bearing to move downward. During the downward movement of the flexible bearing, it will deform as the outer diameter of the elliptical mandrel changes, and finally change from a circular shape to an elliptical shape adapted to the wave generator, and finally be pressed onto the outside of the wave generator to complete the installation. When the installation is completed, the limiting step will limit the flexible bearing, thereby reducing the occurrence of press-fitting deviation.

[0007] In one embodiment: A nylon compression ring is sleeved on the elliptical mandrel, and the nylon compression ring is circular.

[0008] By adopting the above technical solution, since nylon material has good elasticity and wear resistance, it can effectively reduce the wear and collision of the flexible bearing during the press-fitting process. At the same time, when the flexible bearing abuts against the limiting step, the excess downward pressure of the assembly press sleeve can be absorbed by the deformation of the nylon compression ring, reducing the damage caused by overpressure to the flexible bearing.

[0009] In one embodiment: A positioning protrusion is provided at the bottom end of the elliptical mandrel, and a spacer block for fixing the wave generator to the elliptical mandrel is connected to the bottom of the positioning protrusion through a connecting bolt.

[0010] By adopting the above technical solution, radial positioning is carried out through the cooperation of the positioning protrusion and the inner hole of the wave generator, and then the wave generator is fixed on the elliptical mandrel by connecting the spacer block with a connecting bolt.

[0011] In one embodiment: A positioning component for circumferentially positioning the wave generator and a positioning component for keeping the relative fixation between the wave generator and the elliptical mandrel are provided on the base.

[0012] By adopting the above technical solution, through the setting of the positioning component, when the wave generator is placed on the base, circumferential positioning is completed. And the setting of the positioning component enables the elliptical mandrel to be fixed with the wave generator after being installed on the base. Therefore, the installation of both the wave generator and the elliptical mandrel becomes very simple, and there is no need to manually align between the wave generator and the elliptical mandrel.

[0013] In one embodiment: The positioning component includes a positioning sleeve sleeved on the outer circle of the base and a return spring for keeping the positioning sleeve protruding from the upper end face of the base, and the inner circle shape of the positioning sleeve is adapted to the wave generator.

[0014] By adopting the above technical solution, the wave generator can be positioned when it is placed on the base. And when the flexible bearing is press-fitted, the setting of the return spring enables the positioning sleeve to be synchronously pressed down to form an avoidance. At the same time, by limiting the stroke of the positioning sleeve, the occurrence of press-fitting deviation can be reduced.

[0015] In one embodiment: The positioning component includes a clamping structure for fixing the elliptical mandrel, a pressing structure that is lifted upward to press the wave generator against the elliptical mandrel when the elliptical mandrel is clamped to the base, and a releasing structure that drives the positioning sleeve to move downward when the elliptical mandrel is clamped to the base, and an unlocking button is formed on the outer wall of the base for the clamping structure.

[0016] By adopting the above technical solution, the elliptical mandrel can be fixedly installed on the base through the clamping structure, facilitating subsequent press-fitting. The unlocking button is used to quickly release the clamping, facilitating the removal of the elliptical mandrel. The release structure is arranged such that the positioning sleeve automatically moves downward to release the circumferential positioning of the wave generator after the elliptical mandrel is installed, so that during press-fitting, the flexible bearing does not need to push the positioning sleeve downward, thereby reducing damage to the flexible bearing and press-fitting deviation. The pressing structure presses the wave generator against the bottom end of the elliptical mandrel during the installation process of the elliptical mandrel, so that the wave generator does not rotate circumferentially during the entire press-fitting process, ensuring the normal progress of press-fitting.

[0017] In one embodiment: a positioning post is provided at the bottom end of the elliptical mandrel, a slot for inserting the positioning post is provided on the base, and when the positioning post is inserted into the slot, the elliptical mandrel is circumferentially positioned; the pressing structure includes a driving seat that rises as the positioning post moves downward, and a pressing block that moves upward as the driving seat moves upward.

[0018] By adopting the above technical solution, the setting of the positioning post realizes the positioning of the elliptical mandrel during installation, and completes the positioning with the wave generator while installing. At the same time, during the insertion process of the positioning post, the driving seat and the pressing block are driven to act, pressing the wave generator.

[0019] In one embodiment: a compensation spring is provided between the driving seat and the pressing block.

[0020] By adopting the above technical solution, the setting of the compensation spring can, on the one hand, ensure that the pressing block presses the wave generator through the driving seat, and at the same time, can compensate for the stroke of the driving seat, that is, the pressing block can press the wave generator in advance, and at this time, the driving seat can continue to move, and only the pressing force of the pressing block will increase during this process.

[0021] In one embodiment: the release structure includes a sliding post slidably installed on the base, and a lifting plate connected to the sliding post and slidably installed on the base. Both ends of the lifting plate extend out of the base and are connected to the positioning sleeve, and the sliding post is controlled to slide by the positioning post.

[0022] By adopting the above technical solution, the sliding post is set to slide with the positioning post, that is, the sliding post is driven to move downward during the installation process of the elliptical mandrel, and then the lifting plate is connected to the positioning sleeve, so that the positioning sleeve can move up and down synchronously with the sliding post, thereby realizing control through the elliptical mandrel.

[0023] In one embodiment: the driving seat is circumferentially positioned and axially slidably installed on the base, a linkage gear is provided on the base, a first rack structure meshing with the linkage gear is provided on the driving seat, a second rack structure meshing with the linkage gear is provided on the positioning sleeve, and the first rack structure and the second rack structure are respectively arranged on both sides of the linkage gear.

[0024] By adopting the above technical solution, through the design of the linkage gear, the engagement with the first rack structure and the second rack structure realizes the reverse movement of the drive seat and the positioning sleeve. At the same time, the driving of the drive seat can be directly achieved, killing two birds with one stone. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following further describes the present application in detail with reference to the accompanying drawings.

[0028] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0029] Embodiment 1: A press-fitting tool for a flexible bearing 20 of a harmonic reducer, as Figure 1 shown, comprising a base 100, an elliptical mandrel 200, an assembly press sleeve 300 and a nylon press ring 400. The base 100 is used for placing the wave generator 10, and the shape of its upper end face is adapted to the wave generator 10.

[0030] A limiting step 110 for limiting the flexible bearing 20 is provided on the base 100, so that when the flexible bearing 20 is assembled, it is limited by abutting against the limiting step 110. Among them, since the flexible bearing 20 is assembled by pushing the inner ring of the bearing, the limiting step 110 only needs to limit the inner ring of the bearing.

[0031] The elliptical mandrel 200 adopts a gradually changing elliptical cone structure with a smaller upper part and a larger lower part, so that the inner ring of the flexible bearing 20 can be slowly changed into an ellipse during press-fitting, such as the major axis diameter change rate is 0.18 mm / cm, the minor axis diameter change rate is 0.17 mm / cm, etc. And in order to reduce wear, the surface roughness Ra ≤ 0.8 μm.

[0032] The shape of the bottom end face of the elliptical mandrel 200 is the same as that of the wave generator 10 and the size is equal to or larger than that of the wave generator 10. In this embodiment, the bottom end face of the elliptical mandrel 200 is preferably slightly larger than the wave generator 10, on the one hand, it is convenient for press-fitting, and on the other hand, it is easier to align the wave generator 10 and the elliptical mandrel 200.

[0033] A positioning protrusion 210 is provided at the bottom end of the elliptical mandrel 200. The positioning protrusion 210 cooperates with the inner hole of the wave generator 10. A cushion block 220 is connected to the bottom of the positioning protrusion 210 through a connecting bolt 230. The wave generator 10 is fixed to the bottom of the elliptical mandrel 200 through the cushion block 220. Among them, when fixing, it is necessary to first adjust the relative circumferential positions of the wave generator 10 and the elliptical mandrel 200 to ensure that the wave generator 10 does not protrude outside the elliptical mandrel 200 in the circumferential direction.

[0034] The nylon press ring 400 is sleeved on the elliptical mandrel 200, and the nylon press ring 400 is circular.

[0035] The assembly press sleeve 300 is sleeved on the elliptical mandrel 200 for press-fitting the flexible bearing 20. The shape and size of the cross-section of the inner hole of the assembly press sleeve 300 are the same as those of the bottom end face of the elliptical mandrel 200. After the flexible bearing 20 is sleeved on the elliptical mandrel 200, the nylon press ring 400 is sleeved on the elliptical mandrel 200. Then, by pressing down the assembly press sleeve 300, the nylon press ring 400 is pushed to move downward, and the nylon press ring 400 then pushes the flexible bearing 20 sleeve to move downward, so that the inner ring of the flexible bearing 20 slowly changes into an ellipse along with the outer diameter of the elliptical mandrel 200, and finally it is sleeved on the wave generator 10.

[0036] Among them, for the convenience of installation and use, the assembly bushing 300 and the base 100 can be installed on a press, and one end of the nylon pressing ring 400 can also be fixed to the bottom of the assembly bushing 300, so that the nylon pressing ring 400 moves up and down with the assembly bushing 300, and the process of sleeving the nylon pressing ring 400 during each processing can be omitted.

[0037] During assembly, the wave generator 10 and the elliptical mandrel 200 are adjusted circumferentially to complete alignment, and then the two are fixed in relative position after being clamped by the spacer block 220. Then, the elliptical mandrel 200 and the wave generator 10 are placed on the base 100 together, and then the flexible bearing 20 is sleeved from the upper end of the elliptical mandrel 200. Finally, by pressing down the assembly bushing 300, the assembly bushing 300 is sleeved onto the elliptical mandrel 200. At this time, during the process of pressing down the assembly bushing 300, the flexible bearing 20 will be driven to move downward. During the downward movement of the flexible bearing 20, it will deform as the outer diameter of the elliptical mandrel 200 changes, and finally change from a circular shape to an elliptical shape adapted to the wave generator 10, and finally be pressed onto the outside of the wave generator 10 to complete the installation. When the installation is completed, the limiting step 110 will limit the flexible bearing 20, thereby reducing the occurrence of press-fitting deviation.

[0038] Embodiment 2: As Figure 2 shown, the difference from Embodiment 1 is that in this embodiment, the design of first installing the wave generator 10 and the elliptical mandrel 200 and then placing them on the base 100 is not adopted.

[0039] Specifically, in this embodiment, the base 100 is provided with an alignment component 500 for circumferentially positioning the wave generator 10 and a positioning component 600 for keeping the relative fixation between the wave generator 10 and the elliptical mandrel 200.

[0040] A positioning post 240 is provided at the bottom end of the elliptical mandrel 200. The positioning post 240 is arranged on the end face of the positioning protrusion 210. The base 100 is provided with a plug-in post 120 for the positioning post 240 to be inserted. A slot is provided in the plug-in post 120, and when the positioning post 240 is inserted into the slot, the elliptical mandrel 200 is circumferentially positioned. The cross-sections of the slot and the positioning post 240 adopt a polygonal structure.

[0041] The alignment component 500 includes a positioning sleeve 510 sleeved on the outer circle of the base 100 and a return spring 520 for keeping the positioning sleeve 510 protruding from the upper end face of the base 100. The inner circle shape of the positioning sleeve 510 is adapted to the wave generator 10, so that the wave generator 10 must be placed according to the preset position of the positioning sleeve 510. The two ends of the return spring 520 are respectively abutted against the positioning sleeve 510 and the base 100.

[0042] The positioning component 600 includes a clamping structure 610 for fixing the elliptical mandrel 200, a pressing structure 620 that is lifted upward during the clamping of the elliptical mandrel 200 to the base 100 to press the wave generator 10 against the elliptical mandrel 200, and a release structure 630 that drives the positioning sleeve 510 to move downward during the clamping of the elliptical mandrel 200 to the base 100. An unlocking button 615 is formed on the outer wall of the base 100 by the clamping structure 610.

[0043] Refer to the appendix Figure 3 , the release structure 630 includes a sliding column 631 slidably mounted on the base 100 and a lifting plate 632 connected to the sliding column 631 and slidably mounted on the base 100. The sliding column 631 is located in the slot and is connected to the lifting plate 632 by a fixing bolt. The lifting plate 632 is located at the bottom of the sliding column 631, and both ends extend outside the base 100 and are connected to the positioning sleeve 510 by bolts. When installing the elliptical mandrel 200, after the positioning post 240 of the elliptical mandrel 200 is inserted into the slot and moves a certain distance, it will abut against the sliding column 631 and then push the sliding column 631 to move downward synchronously. When the sliding column 631 moves downward, the lifting plate 632 compresses the return spring 520 and drives the positioning sleeve 510 to move downward. The specific state changes can be seen in the appendix Figure 6 and the appendix Figure 7 .

[0044] Among them, refer to the appendix Figure 7 , when the lifting plate 632 slides to the bottom, the installation of the elliptical mandrel 200 is completed. At this time, the positioning sleeve 510 cannot continue to move downward and can be used to limit the flexible bearing 20.

[0045] The pressing structure 620 includes a driving seat 621 that rises as the positioning post 240 moves downward, a pressing block 622 that moves upward as the driving seat 621 moves upward, and a compensation spring 623 provided between the driving seat 621 and the pressing block 622. It should be noted that the driving seat 621 is circumferentially positioned and axially slidably mounted on the base 100 to ensure that the driving seat 621 does not rotate during the lifting and lowering process.

[0046] The pressing block 622 is located above the driving seat 621, and both ends of the compensation spring 623 abut against the pressing block 622 and the driving seat 621 respectively. Among them, in order to prevent the pressing block 622 from being ejected during the process of the compensation spring 623 releasing the elastic force after being compressed, it is preferable to limit the moving stroke of the pressing block 622.

[0047] Refer to the appendix Figure 4, in this embodiment, the pressing block 622 is slidably installed in the compensation spring 623. A fan-shaped or semi-circular connecting protrusion 6211 is provided on the outer side of the driving seat 621. A first flange 6212 is provided on the inner wall of the upper end of the connecting protrusion 6211, and a second flange 6221 is provided on the outer side of the lower end of the pressing block 622. Both the pressing block 622 and the driving seat 621 are sleeved and installed on the insertion column 120. During installation, first insert the pressing block 622 along the opening of the connecting protrusion 6211, then place the compensation spring 623, and then sleeve the pressing block 622, the compensation spring 623, and the driving seat 621 onto the insertion column 120 together. In this way, after installation, the pressing block 622 will be restricted on the driving seat 621 under the abutment of the first convex flange and the second flange 6221.

[0048] A linkage gear 700 is provided on the base 100. A first rack 6213 structure meshing with the linkage gear 700 is provided on the driving seat 621, and a second rack 511 structure meshing with the linkage gear 700 is provided on the positioning sleeve 510. The first rack 6213 structure and the second rack 511 structure are respectively provided on both sides of the linkage gear 700. Through the design of the linkage gear 700, meshing with the first rack 6213 structure and the second rack 511 structure enables the driving seat 621 and the positioning sleeve 510 to move in opposite directions. At the same time, it can directly drive the driving seat 621, killing two birds with one stone.

[0049] As Figure 5 and Figure 6 shown, the clamping structure 610 includes a locking block 611 provided on the insertion column 120, a holding spring 612 for keeping the locking block 611 protruding from the inner wall of the insertion column 120, and a connecting rod structure for controlling the compression spring contraction of the locking block 611. A locking hole 241 is provided on the positioning column 240 to cooperate with the locking block 611.

[0050] The connecting rod structure includes a vertical connecting rod 613 and a horizontal connecting rod 614. The horizontal connecting rod 614 is slidably inserted in the horizontal direction on the base 100, and the end of the horizontal connecting rod 614 extends outside the base 100 to form the above-mentioned unlocking button 615.

[0051] The horizontal connecting rod 614 is exposed at the upper end of the chamber part of the base 100. A limit bolt 616 is connected to the exposed part to limit the stroke of the horizontal connecting rod 614 and prevent the horizontal connecting rod 614 from sliding out of the base 100.

[0052] A guiding inclined surface is provided at one end of the horizontal connecting rod 614 away from the unlocking button 615. The vertical connecting rod 613 is slidably installed on the insertion column 120 in the vertical direction. Guiding inclined surfaces are provided at both ends of the vertical connecting rod 613. The guiding inclined surface at the lower end of the vertical connecting rod 613 abuts and cooperates with the guiding inclined surface on the horizontal connecting rod 614.

[0053] The locking block 611 is provided with a wedge surface that cooperates with the guiding inclined surface at the upper end of the vertical connecting rod 613. Specifically, by pressing the unlocking button 615, the vertical connecting rod 613 can be pushed upward, and then the locking block 611 is driven to compress the spring and retract, thereby releasing the connection with the elliptical core shaft 200.

[0054] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
