Description

Technical Field

[0001] The invention relates to the technical field of reducer assembly, in particular to a modular reducer assembly platform. Background Art

[0002] The harmonic reducer is a transmission device with high precision, high torque and small volume. Its working principle is based on the harmonic effect. It is mainly composed of four basic components: wave generator, flexible gear (flexwheel), flexible bearing and rigid gear (rigid wheel).

[0003] When the input shaft rotates, the wave generator (i.e., the driving wheel) causes the flexible gear to produce controllable elastic deformation through the free bending movement of the connecting rod. This deformation causes relative sliding between the tooth roots of the flexible gear and the tooth roots of the rigid gear, thereby transmitting motion and power. Since the number of teeth on the flexible gear is much greater than that on the rigid gear, the harmonic reducer can achieve a larger transmission ratio.

[0004] During the installation of the harmonic reducer, it is necessary to confirm whether the flatness of the installation surface is good and whether there is any skew. Confirm that the meshing of the flexible wheel and the rigid wheel is 180° symmetrical. When the flexible wheel and the rigid wheel are combined, is there an extreme one-sided meshing? In addition, the harmonic reducer must be installed in a sufficiently clean environment, and no foreign matter can enter the reducer during the installation process, which places extremely high requirements on the installation environment. At the same time, the reducer tooth surface and flexible bearing part are always kept fully lubricated. For this reason, during the installation process, it is necessary to use other equipment to operate so that the harmonic reducer can maintain control of details during the installation process.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figure 1-Figure 10The present invention provides a technical solution: during the installation of the harmonic reducer, the parts of the harmonic reducer are in a stable state when necessary, and need to be in an extremely high-demand environment. During the installation of the parts of the harmonic reducer, the reducer parts need to be wiped to wipe off dust and foreign matter, and keep the harmonic reducer in a clean state. The main parts of the harmonic reducer in the text include a wave generator, a flexible gear, a flexible bearing and a rigid gear. During the installation, it is also necessary to apply lubricating oil to the parts of the harmonic reducer so that the tooth surface and the flexible bearing part of the reducer are always fully lubricated. Based on this, a modular reducer assembly platform is proposed, including a support frame 1, a hydraulic cylinder 2 for driving, an assembly clamping part 4 for clamping the reducer parts, and a support platform 5 for assembly. The reducer parts are clamped to ensure that the axes of the parts coincide with each other, and bumps are avoided during the installation process. The parts can be rotated, and the parts can be wiped or coated with lubricating oil to improve the operating efficiency.

[0037] like Figure 1 and Figure 2 As shown, the hydraulic cylinder 2 is fixed on the upper end of the support frame 1, and the assembly clamping part 4 and the support platform 5 are arranged in the support frame 1, and the two are arranged up and down. The support frame 1 supports the hydraulic cylinder 2, the assembly clamping part 4 and the support platform 5 to fix the position, which is convenient for operation during manual operation. In addition, the support frame 1 has a certain height, which is at the best operating angle for personnel. The hydraulic cylinder 2 is used to push the assembly clamping part 4 to assemble the reducer parts on the support platform 5. The hydraulic cylinder 2 achieves fine control during the pushing process, so that when the hydraulic cylinder 2 controls the assembly clamping part 4 to move, it avoids bumping the reducer parts, so that the degree of coordination of the reducer parts is at the best.

[0038] like Figure 4 As shown, in order to clamp the reducer parts and facilitate clamping of the reducer parts, the assembly clamping part 4 includes a ring 41 for controlling rotation, a first clamping cover 42 and a second clamping cover 43 that are rotatably connected, and multiple groups of clamping shafts 44 for clamping. The first clamping cover 42 and the second clamping cover 43 are arranged at the lower end of the ring 41, and multiple groups of clamping shafts 44 are supported in the first clamping cover 42 and the second clamping cover 43. The second clamping cover 43 is rotated to control the inward and outward movement of the multiple groups of clamping shafts 44. The first clamping cover 42 and the second clamping cover 43 cooperate with each other and have the ability to control the movement of the clamping shaft 44 and the ability to control the clamping shaft 44 to clamp the reducer parts.

[0039] like Figure 1 As shown, the support frame 1 includes a lower support plate 11, an upper support plate 12 and a sheet metal part 13 for fixing. The lower support plate 11 and the upper support plate 12 are arranged up and down, and the sheet metal part 13 is fixed between the two to form a frame. During assembly, the operation is performed inside the frame.

[0040] The hydraulic cylinder 2 is fixed to the upper end of the upper support plate 12 , and the output shaft 3 of the hydraulic cylinder 2 passes through the upper support plate 12 downward. When the hydraulic cylinder 2 is working, the output shaft 3 of the hydraulic cylinder 2 is pushed downward or retracted upward, and the support platform 5 is fixed on the lower support plate 11 .

[0041] like Figure 3 As shown, in order to match the matching reducer parts with the clamped reducer parts, the reducer parts at the lower end need to be clamped and limited, and a clamping cavity 51 for assembly is provided at the upper end of the support platform 5, and a side hole 52 is extended laterally on the inner wall of the clamping cavity 51, and an inner support spring 53 is fixed in the side hole 52, and a support block 54 that can be retracted in the clamping cavity 51 is fixed on the outer side of the inner support spring 53, and the support block 54 is used to support the reducer parts in assembly, and the reducer parts are placed in the clamping cavity 51 and the outer support block 54 is used to support the reducer parts, so that the reducer parts are limited, and the axis thereof also coincides with the axis of the clamping cavity 51, and when the parts are subsequently matched, the axis is in a coincident state to avoid bumps or difficulties in matching.

[0042] like Figure 4 and Figure 5 As shown, the lower end of the output shaft 3 is provided with an annular opening 31 extending upward, and the inner wall of the lower end of the annular opening 31 is provided with an assembly block 32 integrally provided with the output shaft 3. The ferrule 41 is sleeved in the annular opening 31, and the axis of the ferrule 41 coincides with the axis of the output shaft 3. The upper end of the ferrule 41 is provided with an assembly opening 411 cooperating with the assembly block 32, and the lower end of the assembly block 32 abuts against the upper end of the ferrule 41. The lower end of the output shaft 3 is also fixed with a support plate 33 for supporting the ferrule 41. The functions of the annular opening 31 and the support plate 33 are to limit the ferrule 41 and to enable the ferrule 41 to rotate. The rotation of the ferrule 41 allows the entire assembly clamping part 4 to rotate, and the clamped reducer parts are convenient for all-round cleaning and lubricating oil coating. It should also be noted that the meshing of the flexible gear and the rigid gear is 180° symmetrical, and the position can be easily adjusted during the rotation.

[0043] like Figure 5 and Figure 6 As shown, a connecting shaft 412 for manipulation is fixed between the ring 41 and the first clamping cover 42. The connecting shaft 412 is used to control the rotation of the assembly clamping part 4. When the assembly clamping part 4 needs to be rotated, the connecting shaft 412 is turned to achieve rotation, which is convenient for operation.

[0044] like Figure 7As shown, the first clamping cover 42 is provided with a plurality of first sliding cavities 421 penetrating from top to bottom, one ends of the plurality of first sliding cavities 421 all point to the axis of the first clamping cover 42, and the lower end of the first clamping cover 42 is provided with a second sliding cavity 422 which is arranged to coincide with the position of the first sliding cavity 421. The second sliding cavity 422 has the same shape as the first sliding cavity 421 and has a larger area than the first sliding cavity 421. It should be noted that the first sliding cavity 421 and the second sliding cavity 422 coincide with each other, and the second sliding cavity 422 is used to clamp the clamping shaft portion 44 to keep it in a vertical state to avoid displacement, while the first sliding cavity 421 is used to limit the clamping shaft portion 44.

[0045] like Figure 8 As shown, the second clamping cover 43 is fitted with the first clamping cover 42 from bottom to top, and a support rod shaft 432 for limiting is penetrated at the axis of the second clamping cover 43 and the first clamping cover 42. The upper and lower sides of the support rod shaft 432 are circular, and are used to support the second clamping cover 43 and the first clamping cover 42, so that the second clamping cover 43 is located at the lower end of the first clamping cover 42 for rotation. At the same time, the axes of the two also coincide to avoid deviation. The second clamping cover 43 is provided with a matching sliding cavity 431 with the same number as the first sliding cavity 421 and passing through from top to bottom. The matching sliding cavity 431 is inclined, and the width of the matching sliding cavity 431 is the same as that of the first sliding cavity 421. The outer ends of the two coincide and match, and the outer ends of the two coincide, that is, the matching sliding cavity 431 and the first sliding cavity 421 partially coincide, as shown in FIG. Fig. 9 As shown, the overlapping part of the clamping shaft 44 passes through, and the clamping shaft 44 passes through the overlapping position of the two. The second clamping cover 43 is rotated to drive the clamping shaft 44 to move inside the first clamping cover 42. During the rotation of the second clamping cover 43, the overlapping position of the sliding cavity 431 and the first sliding cavity 421 changes, so as to push the clamping shaft 44 to move, so that the clamping shaft 44 moves inward and outward directions, and always maintains a vertical state.

[0046] like Figure 7 and Figure 8As shown, a circle of first annular opening 423 is provided on the inner wall of the side of the first clamping cover 42, and a first clamping plate 424 is fixed to the inner wall of the first annular opening 423, and a circle of second annular opening 433 is provided on the outer side of the second clamping cover 43, and a second clamping plate 434 is fixed to the inner wall of the second annular opening 433, and a connecting spring 425 is fixed between the first clamping plate 424 and the second clamping plate 434, and the connecting spring 425 is embedded in the first annular opening 423 and the second annular opening 433, and the connecting spring 425 is used to reset the position of the second clamping cover 43, and the first annular opening 423 and the second annular opening 433 are used to limit the connecting spring 425 to prevent the connecting spring 425 from generating unnecessary deformation, and the deformed connecting spring 425 has a reaction force, and after releasing the second clamping cover 43, the second clamping cover 43 can be restored, and the clamping shaft portion 44 can move outward to achieve support.

[0047] like Fig.10 As shown, the clamping shaft portion 44 includes a sleeve 441, a circular layer 442 and an inner shaft 443, the circular layer 442 is fixed on the outer side of the sleeve 441, and the two are coaxially arranged, and the circular layer 442 is clamped in the second sliding cavity 422, wherein the upper end and the outer side of the circular layer 442 are squeezed by the second sliding cavity 422, and the lower end is squeezed by the second clamping cover 43, so as to achieve limiting so that it can slide along the second sliding cavity 422, and the diameter of the sleeve 441 is the same as the width of the first sliding cavity 421 and the matching sliding cavity 431, so that during the rotation of the second clamping cover 43, the matching sliding cavity 431 is kept in contact with the outer wall of the sleeve 441, and the rotation is adjustment, and the flexibility is increased, and the inner wall of the sleeve 441 and the outer wall of the inner shaft 443 are both threaded, and the two are sleeved and threadedly matched, which is used to control the length of the inner shaft 443 extending downward, and when clamping the reducer parts, it is avoided to penetrate the reducer parts downward, so that the reducer parts can cooperate with other reducer parts.

[0048] Working principle of the present invention: The harmonic reducer is mainly composed of four basic components: a wave generator, a flexible gear, a flexible bearing and a rigid gear. Among them, the wave generator, the flexible gear, the flexible bearing and the rigid gear all have inner holes. During the clamping process of the assembly clamping part 4, the inner hole is supported through the inner hole and then assembled.

[0049] Push the assembly clamping part 4 upwards to make the assembly opening 411 of the ferrule 41 in the assembly clamping part 4 cooperate with the assembly block 32, keep the assembly clamping part 4 from rotating, and then rotate the second clamping cover 43 to make the multiple clamping shafts 44 move closer to the middle, and then connect the multiple clamping shafts 44 from bottom to top with the reducer parts. It should be noted that the reducer parts are the above-mentioned basic structure of the reducer or other parts. Under the action of the reset of the connecting spring 425, the multiple clamping shafts 44 are dispersed outwards and support the reducer parts. The multiple clamping shafts 44 position the reducer parts so that the axis of the reducer parts is determined. At the same time, the reducer parts are also clamped on the support platform 5. The hydraulic cylinder 2 moves downward, which can make the reducer parts cooperate with each other, determine the position of the axis, and avoid deviation. At the same time, since the multiple clamping shafts 44 support the reducer parts outward and fit against the inner side of the reducer parts, the vertically arranged clamping shafts 44 fit against the inner side of the reducer parts, so that the reducer parts are in a horizontal state to avoid skewing.

[0050] In addition, when the reducer parts are clamped in the assembly clamping part 4, one hand pushes upward and rotates the second clamping cover 43 to prevent the assembly clamping part 4 from rotating, and at the same time, the multiple clamping shafts 44 move inward. The other hand lifts the reducer parts to match the reducer parts with the assembly clamping part 4, and then loosens the second clamping cover 43 to achieve clamping. It can be operated with one hand, which is easy to operate and avoids the reducer parts being damaged or dust sticking due to multiple pick-ups and put-downs.

[0051] After the reducer parts are clamped, the assembly port 411 and the assembly block 32 are uncoupled to achieve rotation, which is convenient for cleaning the outer hand-held position again to avoid dust and foreign matter. Lubricating oil can also be applied to the reducer parts during rotation, making the operation simpler and avoiding dust and foreign matter from adhering to the lubricating oil.

[0052] Before clamping the reducer part, the downward extension length of the inner shaft 443 is adjusted according to the size of the reducer part, so that after the inner shaft 443 clamps the reducer part, it will not extend downward out of the reducer part to affect the assembly of the reducer.

[0053] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0054] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
