Modular automated reduction gear assembly fixture

Abstract

This application relates to the field of assembly tooling, specifically a modular automated reducer assembly tooling, including: a base plate, a steel wheel mounting seat, a support column, an input shaft fixing module, a support seat, a support rod, a part retrieval module, a shelf, and a propulsion module. After the steel wheel is fixedly mounted on the steel wheel mounting seat and the input shaft is fixedly mounted on the input shaft fixing module, the support seat drives the support rod to rotate horizontally, causing the part retrieval module to remove parts from the shelf. Subsequently, the support seat drives the support rod back to its initial position, and the propulsion module drives the part retrieval module to perform assembly. During assembly, by causing relative displacement between the adjusting rod and the support rod, the distance between the two sliding plates is increased, thereby increasing the pressure between the pulley and the inner surface of the annular part, thus fixing the part. Furthermore, when the part retrieval module clamps the flexible wheel and flexible bearing, it can also cause the flexible wheel and flexible bearing to deform in accordance with the harmonic generator, facilitating the assembly of the flexible wheel and flexible bearing.

Description

Technical Field

[0001] This application relates to the field of assembly tooling, and in particular to modular automated reducer assembly tooling. Background Technology

[0002] The existing harmonic reducer includes: a steel wheel, a flexible wheel, a harmonic generator, a flexible bearing, an input shaft, and an output shaft. The input shaft is fixedly connected to the harmonic generator, the flexible wheel is fixedly connected to the output shaft, and the flexible wheel is connected to the harmonic generator through a flexible bearing. The outer surface of the flexible wheel is provided with a toothed ring that meshes with the steel wheel.

[0003] When assembling a harmonic generator, because the harmonic generator is elliptical, external force is needed to deform the flexible wheel and flexible bearing to match the harmonic generator before they can be assembled onto the harmonic generator. In addition, the mismatch in the number of teeth between the flexible wheel and the steel wheel can also easily lead to misalignment during assembly. Summary of the Invention

[0004] To address the problems existing in the prior art, this application provides a modular automated reducer assembly fixture.

[0005] The modular automated reducer assembly fixture includes: a base plate, a steel wheel mounting seat, a support column, an input shaft fixing module, a support base, a support rod, a parts-retrieving module, a shelf, and a propulsion module.

After installation, the movable plates can slide radially along the support shaft. The output end of cylinder A is fixedly connected to the push rod, and one end of the push rod is located inside the support shaft to drive the movable plates to slide.

[0007] Furthermore, several wedges are fixedly connected to the push rod, with each pair of wedges corresponding to a moving plate. Each moving plate is provided with two wedge-shaped grooves, which cooperate with the wedges to drive the moving plate to move radially along the push rod when the push rod moves axially.

[0008] Furthermore, the component retrieval module includes a fixed plate, a sliding plate, a connecting rod, an adjusting rod, and a pulley; wherein the fixed plate is fixedly connected to the adjusting rod, and two symmetrically arranged sliding plates are slidably connected to the fixed plate, each sliding plate is rotatably connected to a pulley seat, the pulley is rotatably mounted on the pulley seat, one end of the connecting rod is rotatably connected to the sliding plate, and the other end of the connecting rod is rotatably connected to the support rod.

[0009] Furthermore, the fixed plate has multiple grooves along the moving direction of the slide plate, and a slider is fixedly connected to the slide plate at the corresponding groove. The sliding connection between the slide plate and the pulley is realized through the cooperation of the slider and the groove.

[0010] Furthermore, the propulsion module includes a drive rod, a cylinder B, an electric cylinder B, a pressure rod, a fixed rod, and a friction plate B. The cylinder B is fixedly mounted on the support base, and the output shaft of the cylinder B is fixedly connected to the drive rod. The end of the drive rod is fixedly connected to the adjusting rod, and the drive rod is movably inserted into the support rod. A connecting block is fixedly connected to the drive rod, and two electric cylinders B are fixedly connected to the radial sides of the connecting block. The output shaft of the electric cylinder B is rotatably connected to the pressure rod, and the end of the pressure rod is rotatably connected to the friction plate B. A fixed rod is also fixedly connected to the connecting block, and the fixed rod is rotatably connected to the pressure rod. The connection point between the fixed rod and the pressure rod is located between the connection point between the pressure rod and the electric cylinder B and the connection point between the pressure rod and the friction plate B. The inner surface of the friction plate B is adapted to the outer surface of the support rod.

[0011] Furthermore, there are multiple support mounting cavities between the support rod and the drive rod, and a support is installed in each support mounting cavity. The inner surface of the support is connected to the drive rod, and the outer surface of the support is connected to the support rod.

[0012] Furthermore, the support member includes a ball cage, a ball bearing, and a fixed shaft. Multiple ball cages are provided, and each pair of adjacent ball cages are fixedly connected by several fixed shafts. Multiple cylindrical through holes extending radially are provided inside the ball cage, and a ball bearing is provided in each cylindrical through hole.

[0013] Furthermore, an electric cylinder A is also installed inside the support base, and a friction plate A is fixedly connected to the output shaft of the electric cylinder A. The top of the friction plate A is adapted to the outer surface of the support rod.

[0014] Furthermore, the shelf includes an arc-shaped oil cavity, clamps, and several telescopic rods slidably connected to the arc-shaped oil cavity. The number of clamps is at least three, one of which is located in the middle of the arc-shaped oil cavity, and two of which are located on both sides of the arc-shaped oil cavity. The clamps are fixedly connected to the telescopic rods one by one. A piston is fixedly connected to one side of the telescopic rod located inside the arc-shaped oil cavity. The arc-shaped oil cavity is provided with a compression chamber adapted to the piston.

[0015] The technical effects and advantages of this application are as follows:

[0016] In this application, after the steel wheel is fixedly installed on the steel wheel mounting base and the input shaft is fixedly installed on the input shaft fixing module, the support rod is driven to rotate horizontally by the support base, so that the control part retrieval module takes out the part from the shelf. Then the support base drives the support rod back to the initial position, and the part retrieval module is driven to assemble by the push module.

[0017] During assembly, the distance between the two slides is increased by causing relative displacement between the adjusting rod and the support rod, thereby increasing the pressure between the pulley and the inner surface of the ring-shaped part and thus fixing the part.

[0018] On the other hand, when the flexible wheel and flexible bearing are clamped by the part-picking module, the flexible wheel and flexible bearing can also be deformed to match the harmonic generator, so as to facilitate the assembly of the flexible wheel and flexible bearing.

[0019] The relative distance between the two slides is adjustable, so it can accommodate parts of different sizes when clamping parts through the part-grabbing module.

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] Furthermore, in the application, the terms "first," "second," and other similar words are not intended to imply any order, quantity, or importance, but are merely used to distinguish different elements, and the terms "upper," "lower," "left," "right," and other similar words are merely positional relationships in the accompanying drawings.

[0039] The existing harmonic reducer includes: a steel wheel, a flexible wheel, a harmonic generator, a flexible bearing, an input shaft, and an output shaft. The input shaft is fixedly connected to the harmonic generator, the flexible wheel is fixedly connected to the output shaft, and the flexible wheel is connected to the harmonic generator through a flexible bearing. The outer surface of the flexible wheel is provided with a toothed ring that meshes with the steel wheel.

[0040] When assembling a harmonic generator, because the harmonic generator is elliptical, external force is needed to deform the flexible wheel and flexible bearing to match the harmonic generator before they can be assembled onto the harmonic generator. In addition, the mismatch in the number of teeth between the flexible wheel and the steel wheel can also easily lead to misalignment during assembly.

[0041] like Figure 1 As shown in the embodiment of this application, a modular automated reducer assembly fixture is provided, including: a base plate 1, a steel wheel mounting seat 2, a support column 3, an input shaft fixing module 4, a support seat 5, a support rod 6, a parts retrieval module 7, a storage rack 8, and a propulsion module 9, wherein...

[0042] The steel wheel mounting base 2 is fixedly connected to the base plate 1 and is used to fix the steel wheel in the above-mentioned harmonic reducer. After fixing the steel wheel, other parts are assembled. The upper surface of the steel wheel mounting base 2 is an annular groove. The steel wheel mounting base 2 is provided with multiple bolt holes to fix the steel wheel by bolts.

[0043] The support column 3 is located on one side of the steel wheel mounting base 2 and is fixedly connected to the base plate 1 to support the input shaft fixing module 4;

[0044] The input shaft fixing module 4 is used to install the input shaft of the above-mentioned harmonic reducer. After the input shaft is installed, it is coaxial with the steel wheel installed in the steel wheel mounting seat 2.

[0045] The support base 5 is rotatably connected to the base plate 1, the steel wheel mounting base 2 is located between the support base 5 and the column 3, and the support rod 6 is installed on the support base 5;

[0046] One end of the support rod 6 is equipped with a part-removing module 7, and the other end of the support rod 6 is equipped with a propulsion module 9. When the steel wheel in the above-mentioned harmonic reducer is installed in the steel wheel mounting seat 2, the steel wheel is coaxial with the support rod 6.

[0047] The part-grabbing module 7 is used to hold the parts;

[0048] The propulsion module 9 is used to drive the part-grabbing module 7 to clamp the parts and to drive the part-grabbing module 7 to perform assembly work.

[0049] The shelf 8 is fixedly connected to the base plate 1 and is located on one side of the support base 5, used to place parts;

[0050] Thus, after the steel wheel is fixedly installed on the steel wheel mounting base 2 and the input shaft is fixedly installed on the input shaft fixing module 4, the support rod 6 is rotated horizontally by the support base 5, so that the control part retrieval module 7 takes out the part from the shelf 8. Then the support base 5 drives the support rod 6 back to the initial position, and the part retrieval module 7 is driven by the push module 9 to perform assembly.

[0051] It should be noted that the base plate 1 serves as the support for the entire tooling, and its structure includes, but is not limited to, the plate-shaped support member shown in the figure.

[0052] Specifically:

[0053] like Figure 2 As shown, in one embodiment of this application, the input shaft fixing module 4 includes a support shaft 41, a positioning baffle 42, a moving plate 43, a cylinder A44, a positioning post 45, and a push rod 46. The support shaft 41, the positioning baffle 42, and the cylinder A44 are all fixedly connected to the support column 3. The support shaft 41 is hollow inside, and several circumferentially equidistant moving plates 43 are installed inside the support shaft 41. After installation, the moving plates 43 can slide radially along the support shaft 41. The output end of the cylinder A44 is fixedly connected to the push rod 46. One end of the push rod 46 is located inside the support shaft 41 and is used to drive the moving plate 43 to slide. The positioning post 45 is located at one end of the support shaft 41 and is used to coaxially position the support rod 6 during assembly. The part removal module 7 is provided with a positioning hole that matches the positioning post 45.

[0054] like Figure 3 As shown, several wedges 47 are fixedly connected to the push rod 46. Every two wedges 47 correspond to a moving plate 43. Each moving plate 43 is provided with two wedge grooves 48. The wedge grooves 48 cooperate with the wedges 47, so that when the push rod 46 moves axially, it drives the moving plate 43 to move radially along the push rod 46, thus fixing the input shaft of the harmonic reducer.

[0055] In one embodiment of this application, the positioning baffle 42 is threadedly connected to the support column 3, so that the axial position of the positioning baffle 42 can be adjusted by rotating the positioning baffle 42.

[0056] like Figure 4 As shown, in one embodiment of this application, the component retrieval module 7 includes a fixed plate 71, a sliding plate 72, a connecting rod 73, an adjusting rod 74, and a pulley 75; wherein the fixed plate 71 is fixedly connected to the adjusting rod 74, and two symmetrically arranged sliding plates 72 are slidably connected to the fixed plate 71, and a pulley seat 76 is rotatably connected to each sliding plate 72, and the pulley 75 is rotatably mounted on the pulley seat 76; one end of the connecting rod 73 is rotatably connected to the sliding plate 72, and the other end of the connecting rod 73 is rotatably connected to the support rod 6. With this configuration, when the adjusting rod 74 moves axially relative to the support rod 6, the distance between the two pulley seats 76 can be changed through the connecting rod 73;

[0057] It should be noted that most of the parts of the harmonic reducer are ring-shaped. During assembly, the relative displacement between the adjusting rod 74 and the support rod 6 is made to increase the distance between the two sliding plates 72, thereby increasing the pressure between the pulley 75 and the inner surface of the ring-shaped part, and thus fixing the part.

[0058] On the other hand, when the flexible wheel and flexible bearing are clamped by the part-picking module 7, the flexible wheel and flexible bearing can also be deformed to match the harmonic generator, so as to facilitate the assembly of the flexible wheel and flexible bearing.

[0059] The relative distance between the two slide plates 72 is adjustable, so that when the parts are clamped by the part-grabbing module 7, parts of different sizes can be accommodated.

[0060] like Figure 5 As shown, multiple grooves 78 are provided on the fixed plate 71 along the moving direction of the slide plate 72. A slider 77 is fixedly connected to the slide plate 72 at the location of the groove 78. The sliding connection between the slide plate 72 and the pulley 75 is realized through the cooperation of the slider 77 and the groove 78.

[0061] like Figure 6 As shown, in one embodiment of this application, the propulsion module 9 includes a drive rod 91, a cylinder B92, an electric cylinder B93, a pressure rod 94, a fixed rod 95, and a friction plate B96. The cylinder B92 is fixedly mounted on the support base 5. The output shaft of the cylinder B92 is fixedly connected to the drive rod 91. The end of the drive rod 91 is fixedly connected to the adjusting rod 74. The drive rod 91 is movably inserted into the support rod 6. A connecting block 97 is fixedly connected to the drive rod 91. Two electric cylinders B93 are fixedly connected to the radial sides of the connecting block 97. The output shaft of the electric cylinder B93 is rotatably connected to the pressure rod 94. The end of the pressure rod 94 is rotatably connected to the friction plate B96. A fixed rod 95 is also fixedly connected to the connecting block 97. The fixed rod 95 is rotatably connected to the pressure rod 94. The connection point between the fixed rod 95 and the pressure rod 94 is located between the connection point between the pressure rod 94 and the electric cylinder B93 and the connection point between the pressure rod 94 and the friction plate B96. The inner surface of the friction plate B96 is adapted to the outer surface of the support rod 6.

[0062] With this configuration, when the electric cylinder B93 pushes one end of the pressure rod 94 to move, the inner surface of the friction plate B96 is in contact with the outer surface of the support rod 6, and there is a certain pressure between the friction plate B96 and the support rod 6. This fixes the drive rod 91 and the support rod 6 in place. When the cylinder B92 drives the drive rod 91 to move, the support rod 6 will move along with the drive rod 91, thereby causing the entire part-removing module 7 to move. When the electric cylinder B93 pulls back one end of the pressure rod 94, the connection between the friction plate B96 and the support rod 6 is broken. At this time, when the cylinder B92 drives the drive rod 91 to move, it will push the slide plate 72 to move through the connecting rod 73.

[0063] It should be noted that to achieve the above transmission process, it is necessary to ensure that the frictional force between the drive rod 91 and the support rod 6 is less than the frictional force between the support rod 6 and the support seat 5.

[0064] Therefore, such as Figure 7As shown, in one embodiment of this application, there are multiple support mounting cavities 61 between the support rod 6 and the drive rod 91. Each support mounting cavity 61 is equipped with a support member 62. The inner surface of the support member 62 is connected to the drive rod 91, and the outer surface of the support member 62 is connected to the support rod 6. The friction between the support rod 6 and the drive rod 91 is reduced by the support member 62.

[0065] like Figure 8 As shown, in one embodiment of this application, the support member 62 includes a ball cage 621, a ball bearing 622, and a fixed shaft 623. Multiple ball cages 621 are provided, and each pair of adjacent ball cages 621 are fixedly connected by several fixed shafts 623. Multiple cylindrical through holes extending radially within the ball cage 621 are provided, and a ball bearing 622 is provided in each cylindrical through hole. This arrangement ensures that the cavity through which the drive rod 91 passes within the ball cage 621 fits against the ball bearing 622, and the outer side of the ball bearing 622 fits against the inner surface of the support rod 6. The arrangement of multiple ball cages 621 ensures the stability of the connection between the drive rod 91 and the support rod 6.

[0066] The greater the friction between the support base 5 and the support rod 6, the greater the energy consumed when driving the support rod 6 to move; the smaller the friction between the support base 5 and the support rod 6, the easier it is for the support rod 6 to move under the drive of the drive rod 91.

[0067] Therefore, as Figure 7 As shown, in order to flexibly adjust the friction between the support base 5 and the support rod 6, in one embodiment of this application, an electric cylinder A51 is also installed in the support base 5. A friction plate A52 is fixedly connected to the output shaft of the electric cylinder A51. The top of the friction plate A52 is adapted to the outer surface of the support rod 6. With this configuration, the electric cylinder A51 can drive the friction plate A52 to fit against the support rod 6 to fix the support rod 6.

[0068] Thus, when it is necessary to adjust the distance between the two slide plates 72, the friction plate A52 can be driven by the electric cylinder A51 to fix the support rod 6, and the friction plate B96 can be driven by the electric cylinder B93 to disconnect from the support rod 6; when it is necessary to drive the entire part-removing module 7 to move, the friction plate A52 can be driven by the electric cylinder A51 to disconnect from the support rod 6, and the friction plate B96 can be driven by the electric cylinder B93 to fit against the support rod 6.

[0069] like Figure 1 As shown, when a part needs to be taken out from the shelf 8, the support rod 6 can be rotated by the support base 5 to move the part retrieval module 7 to the shelf 8, and the part retrieval module 7 can be driven by the push module 9 to complete the part retrieval operation; when the part is placed in the shelf 8, the shelf 8 is required to have a certain limiting effect on the part.

[0070] Therefore, as Figure 9 As shown, in one embodiment of this application, the shelf 8 includes an arc-shaped oil cavity 81, clamping plates 82, and a plurality of telescopic rods 83 slidably connected to the arc-shaped oil cavity 81. The number of clamping plates 82 is at least three, one of which is located in the middle of the arc-shaped oil cavity 81, and two of which are located on both sides of the arc-shaped oil cavity 81. The clamping plates 82 are fixedly connected to the telescopic rods 83 one by one. A piston is fixedly connected to one side of the telescopic rod 83 located in the arc-shaped oil cavity 81. The arc-shaped oil cavity 81 is provided with a compression chamber adapted to the piston. With this configuration, when a part is placed on the clamping plate 82 in the middle of the arc-shaped oil cavity 81, the clamping plate 82 in the middle of the arc-shaped oil cavity 81 descends under the action of gravity, thereby forcing the clamping plates 82 on both sides of the arc-shaped oil cavity 81 to move toward the part, so as to realize the clamping action.

[0071] In addition, after the parts are placed in the shelf 8, they need to be lifted before they can be taken out of the shelf 8. Therefore, after the parts are placed in the shelf 8, the height of the part's axis is lower than the height of the support rod 6's axis. In this way, when the two slides 72 in the part retrieval module 7 move away from each other, the action of lifting the parts can be realized.

[0072] Finally, it should be noted that the above description is only a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
