Description

[0001] The application date of this application is July 15, 2024, the application number is CN202410943218.4, and the name of the invention is an assembly device for reducer production. Technical Field

[0002] The invention relates to the field of reducer production, and in particular to an assembly device for reducer production. Background Art

[0003] The reducer is an independent component that realizes the deceleration function through gear transmission, worm transmission or gear-worm transmission enclosed in a rigid housing. It can effectively match the speed and transmit torque between the prime mover and the working machine or actuator, so as to meet the different needs of various mechanical equipment for power transmission. The design of the reducer is based on the principle of gear meshing. Through the combination of gears with different numbers of teeth, the conversion of high speed and low torque of the input shaft to low speed and high torque of the output shaft is realized. In the production process of the reducer, we need to use the hydraulic device to assemble the bearing at the bottom of the inner cavity of the reducer housing, and then press the transmission gear on the bearing. However, the hydraulic device press joint design used in the current reducer production is relatively small, which requires workers to manually adjust the position of the reducer housing when assembling the bearing to ensure that the central axis of the bearing in the inner cavity of the reducer housing is accurately aligned with the central axis of the hydraulic device press joint. This step is not only cumbersome to operate, but also as the workers work longer, their attention may be weakened, thereby increasing the risk of misalignment between the central axis of the bearing and the hydraulic device press joint. Once this happens, the bearing may be tilted during the press fitting process, which has a potential adverse effect on the subsequent stable operation of the reducer. Summary of the invention

[0004] The purpose of the present invention is to solve the problems in the background technology and to propose an assembly device for speed reducer production.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an assembly device for reducing machine production, comprising a bottom plate, a main shell and a mounting beam are welded on the top of the bottom plate, a first rotating rod is rotatably connected to the outer peripheral wall of the main shell, a second rotating rod is rotatably connected to the inner cavity of the main shell, a worm gear and a rotating disk are welded on the outer peripheral wall of the second rotating rod, and the worm gear is meshed with the first rotating rod, a plurality of curved grooves are opened on the top of the rotating disk, and the plurality of curved grooves are equidistantly distributed on the top of the rotating disk, a plurality of vertical rods are slidably arranged on the top of the main shell, and the bottom of each vertical rod is slidably arranged in each curved groove in a one-to-one correspondence, a clamping block is welded on the top of each vertical rod, an internal threaded barrel is threadedly connected to the end of the first rotating rod, a vertical plate is welded on the outer wall of the side of the internal threaded barrel away from the first rotating rod, a T-shaped slot is opened on the outer wall of the side of the vertical plate close to the internal threaded barrel, an electric telescopic rod is fixedly installed on the top of the mounting beam, a press-fitting rod is fixedly installed on the telescopic end of the bottom of the electric telescopic rod, and a first rack is slidably arranged in the inner cavity of the press-fitting rod, The third gear is welded on the third gear and is meshed with the first gear of the first gear.

[0006] The cam is provided with a plurality of spring plates at the bottom, and a plurality of spring plates are provided on the top of the plurality of bearings, and a plurality of spring plates are provided on the bottom of the plurality of bearings.

[0007] In the above-mentioned assembly device for reducer production, a plurality of sliding rods three are welded on the inner wall of the press-fit shell, and an auxiliary pressure block is slidably arranged on the outer peripheral wall of each of the sliding rods three, and a spring two is wound around the outer peripheral wall of each of the sliding rods three, and each spring two is respectively connected between each auxiliary pressure block and the inner wall of the press-fit shell, and each auxiliary pressure block has an inclined surface on one side close to the press-fit rod. When a plurality of press-fit shells are synchronously contracted, the gap between two adjacent press-fit shells gradually decreases, and the auxiliary pressure block moves with the press-fit shell toward the inner cavity of the press-fit rod. At this time, the auxiliary pressure block enters the interior of the assembly shell under the pushing action of the cavity wall of the press-fit rod.

[0008] In the above-mentioned assembly device for reducer production, a lower pressure plate is welded on the outer peripheral wall of the press-fitting rod, a mounting frame is welded on the top of the main shell, a press rod is slidably arranged on the top of the mounting frame, a sleeve is slidably arranged on the bottom of the press rod, a spring three is wound around the outer peripheral wall of the press rod, and the spring three is connected between the sleeve and the mounting frame, a tooth block is welded at the bottom of the sleeve, and a snap-in gear meshing with the tooth block is welded on the outer peripheral wall of the first rotating rod. When the press-fitting rod moves downward, the lower pressure plate will drive the press rod, sleeve and tooth block to move downward, so that the tooth block meshes with the snap-in gear, thereby reducing the probability of the first rotating rod loosening due to vibration generated during the subsequent assembly of the bearing.

[0009] In the above-mentioned assembly device for reducer production, a plurality of sliding grooves are opened on the top of the main shell, and the plurality of sliding grooves are equidistantly distributed circumferentially on the top of the main shell, a sliding rod is welded in each sliding groove, and each vertical rod is slidably arranged on each sliding rod one by one.

[0010] In the above-mentioned assembly device for reducer production, a plurality of rubber pads are fixedly installed on the outer wall of the clamping block close to the center of the main shell. Since the rubber pads deform under force, the clamping block can maintain a stable clamp on the reducer housing while not easily scratching the reducer housing.

[0011] In the above-mentioned assembly device for reducer production, a T-block is welded on the outer wall of the first rack, and the T-block is slidably arranged in the T-slot, a support plate is welded on the inner wall of the press rod, and the third rotating rod is rotatably connected to the support plate.

[0013] Compared with the existing technology, the advantages of this moisture-proof distribution cabinet are:

[0014] 1. The press-fitting plane formed by the contracted press-fitting shells and the bottom of the press-fitting rod can just cover most of the area near the center of the inner cavity of the reducer housing, so that workers no longer need to manually move the reducer housing to align the bearing with the press-fitting rod; because the clamping blocks and the press-fitting shells can be contracted and expanded synchronously, and the auxiliary pressure blocks can also contract and expand with the movement of the press-fitting shells, the device can assemble reducer housings within a certain size range, expanding the scope of use of the device;

[0015] 2. When several press-fit shells are expanded synchronously, the gap between two adjacent press-fit shells gradually increases, and the auxiliary pressure block moves toward the outside of the press-fit rod following the press-fit shell. At this time, the auxiliary pressure block moves out of the inner cavity of the press-fit shell under the elastic force of the second spring, so as to fill the gap between the two adjacent press-fit shells and avoid the gap from being too large to affect the assembly of the bearing;

[0016] 3. When the press rod moves downward, it will drive the lower pressure plate to move downward, and the lower pressure plate will drive the press rod, sleeve and gear block to move downward, so that the gear block is engaged with the clamping gear, so as to reduce the probability of the first rotating rod loosening due to the vibration generated during the subsequent assembly of the bearing;

[0017] 4. The contact surface between the extrusion plate and the press-fit housing is an inclined surface that abuts against each other, so that the horizontally moving extrusion plate will apply a force to the press-fit housing, thereby offsetting a part of the reaction force applied to the press-fit housing by the bearing, thereby reducing the risk of bending and fracture at the connection between the press-fit housing and the connecting block;

[0018] To sum up, the pressing plane formed by several press-fit shells and the bottom of the press-fit rod can cover the bottom of the inner cavity of the reducer housing. Workers no longer need to manually move the reducer housing to align the bearing with the press-fit rod, and the bearing is not prone to tilting after pressing. The set extrusion plate reduces the risk of bending and breaking at the connection between the press-fit shell and the connecting block. The set auxiliary pressure block expands the use range of the device. The set tooth block meshes with the clamping gear, reducing the probability of the first rotating rod loosening due to vibration generated during the subsequent assembly of the bearing.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] Reference Figure 1-Figure 11, an assembly device for reducing machine production, including a base plate 1, a main shell 2 and a mounting beam 3 are welded on the top of the base plate 1, a first rotating rod 4 is rotatably connected to the outer peripheral wall of the main shell 2, a second rotating rod 5 is rotatably connected to the inner cavity of the main shell 2, a worm gear 6 and a rotating disk 7 are welded on the outer peripheral wall of the second rotating rod 5, and the worm gear 6 is meshed with the first rotating rod 4, and the end of the first rotating rod 4 is threadedly connected with an internal threaded tube 11. It should be noted that the middle part of the first rotating rod 4 is a worm pattern meshed with the worm gear 6, and the end of the first rotating rod 4 is a spiral pattern meshed with the internal threaded tube 11. The rotating first rotating rod 4 drives the worm gear 6 to rotate, the worm gear 6 drives the second rotating rod 5 to rotate, and the second rotating rod 5 drives the disc to rotate; a plurality of curved grooves 8 are opened on the top of the rotating disk 7, and the plurality of curved grooves 8 are equidistantly distributed on the top of the rotating disk 7, a plurality of vertical rods 9 are slidably arranged on the top of the main shell 2, and the bottom of each vertical rod 9 is slidably arranged in each curved groove 8 one by one, and the main shell A plurality of sliding grooves 46 are provided on the top of the main body 2, and the plurality of sliding grooves 46 are equidistantly distributed circumferentially on the top of the main shell 2, a sliding rod 47 is welded in each sliding groove 46, and each vertical rod 9 is slidably arranged on each sliding rod one by one, and a clamping block 10 is welded on the top of each vertical rod 9. Since the curvature of the curved groove 8 on the disc gradually shrinks toward the center of the disc, and the bottom of the vertical rod 9 is slidably arranged in the curved groove 8, the rotating disc will push the plurality of vertical rods 9 to shrink toward the center of the main shell 2, so that the vertical rod 9 drives the clamping block 10 to abut against the outer wall of the reducer housing 53, so that the reducer housing 53 remains stable at the top of the main shell 2; in addition, a plurality of rubber pads 48 are fixedly installed on the outer wall of the clamping block 10 on one side close to the center of the main shell 2. Since the rubber pad 48 will deform under force, the clamping block 10 can stably clamp the reducer housing 53 while not easily scratching the reducer housing 53.

[0034] Furthermore, a vertical plate 12 is welded on the outer wall of the inner threaded tube 11 away from the first rotating rod 4, a limiting rod three 54 is welded on the outer peripheral wall of the main shell 2, and the vertical plate 12 is slidably set on the limiting rod three 54, and the set limiting rod three 54 limits the vertical plate 12 during the movement process, and a T-shaped groove 13 is opened on the outer wall of the vertical plate 12 close to the inner threaded tube 11. An electric telescopic rod 14 is fixedly installed on the top of the mounting beam 3, and a press-fitting rod 15 is fixedly installed on the telescopic end of the bottom of the electric telescopic rod 14. A first rack 16 is slidably set in the inner cavity of the press-fitting rod 15, and the first rack 16 is slidably set in the inner cavity of the press-fitting rod 15. One end of a rack 16 close to the vertical plate 12 is slidably set in the T-slot 13, a T-block 49 is welded on the outer wall of the first rack 16, and the T-block 49 is slidably set in the T-slot 13, and the first rotating rod 4 drives the internal threaded tube 11, the vertical plate 12, the T-block 49 and the first rack 16 to move in a direction away from the main shell 2; a third rotating rod 17 is rotatably connected in the inner cavity of the press-fitting rod 15, a support plate 50 is welded on the inner wall of the press-fitting rod 15, and the third rotating rod 17 is rotatably connected to the support plate 50, and a third rotating rod 17 is welded on the top of the third rotating rod 17 to mesh with the first rack 16 There are three gears 18, and a gear ring 19 is welded at the bottom of the third rotating rod 17. The moving first rack 16 will drive the third gear 18, the third rotating rod 17 and the gear ring 19 to rotate; a plurality of first threaded rods 20 are rotatably connected in the inner cavity of the press-fitting rod 15, and a bevel gear 21 meshing with the gear ring 19 is welded on the outer wall of each first threaded rod 20 close to the gear ring 19. The rotating gear ring 19 will drive the plurality of bevel gears 21 to rotate synchronously, and a thread block 22 is threadedly connected on the outer peripheral wall of each first threaded rod 20, and a connecting thread is welded at the bottom of each thread block 22. Block 23, a press-fit shell 24 is welded at the bottom of each connecting block 23, the rotating bevel gear 21 drives the first threaded rod 20 to rotate, the rotating first threaded rod 20 drives the threaded block 22 to move toward the center of the press-fit rod 15, and the threaded block 22 drives the connecting rod and the press-fit shell 24 to shrink into the inner cavity of the press-fit rod 15; in addition, a plurality of limit rods 51 are welded on the inner wall of the press-fit rod 15, and each threaded block 22 is slidably arranged on each limit rod 51 in a one-to-one manner, and the set limit rods 51 limit the threaded block 22 during the movement process.

[0035] Furthermore, two mounting plates 25 are welded on the outer wall of the threaded block 22, and a sliding bar 26 is welded between the two mounting plates 25. A slider 27 is slidably arranged on the outer peripheral wall of the sliding bar 26, and a spring 28 is wound around the outer peripheral wall of the sliding bar 26, and the spring 28 is located between one of the mounting plates 25 and the slider 27. A second rack 29 is welded on the outer wall of the slider 27 away from the threaded block 22, and a push plate 30 is welded at the bottom of the second rack 29. A push rod 35 is welded on the top of the press-fit shell 24, and the top of the push rod 35 abuts against the bottom of the push plate 30. When the connection between the press-fit shell 24 and the connecting block 23 has a tendency to bend and break, the set press-fit shell 24 will drive the push rod 35 to move up, and the push rod 35 will push the push plate 30, the second rack 29 and the slider 27 to move up; a second threaded rod 31 is rotatably connected to the outer wall of the threaded block 22, and one end of the second threaded rod 31 is rotatably connected to the outer wall of the connecting block 23, and the second threaded rod 31 is far away from the outer wall The second gear 32 meshing with the second rack 29 is welded on the outer wall of the side away from the connecting block 23, and a threaded plate 33 is threadedly connected to the outer peripheral wall of the second threaded rod 31, and an extrusion plate 34 is welded on the bottom of the threaded plate 33. The upwardly moved second rack 29 will drive the second gear 32 and the second threaded rod 31 to rotate, and the second threaded rod 31 will drive the threaded plate 33 and the extrusion plate 34 to move horizontally in the direction of the connecting block 23. Since the contact surface between the extrusion plate 34 and the press-fit shell 24 is an inclined surface abutting each other, the horizontally moving extrusion plate 34 will apply a force to the press-fit shell 24, thereby offsetting a part of the reaction force applied to the press-fit shell 24 by the bearing, wherein each threaded block 22 is respectively welded with a limiting rod 52 between each connecting block 23, and each threaded plate 33 is slidably arranged on each limiting rod 52 in a one-to-one manner, and the set limiting rod 52 limits the threaded plate 33 during the movement.

[0036] Furthermore, a plurality of slide bars 36 are welded on the inner wall of the press-fitting shell 24, and an auxiliary pressure block 37 is slidably arranged on the outer peripheral wall of each slide bar 36, and a spring 2 38 is wound around the outer peripheral wall of each slide bar 36, and each spring 2 38 is respectively connected between each auxiliary pressure block 37 and the inner wall of the press-fitting shell 24, and a side of each auxiliary pressure block 37 close to the press-fitting rod 15 is an inclined surface. When a plurality of press-fitting shells 24 are synchronously contracted, the gap between two adjacent press-fitting shells 24 gradually decreases, and the auxiliary pressure block 37 moves with the press-fitting shell 24 toward the inner cavity of the press-fitting rod 15. At this time, the auxiliary pressure block 37 enters the interior of the assembly shell under the action of the pushing of the cavity wall of the press-fitting rod 15, and the spring 2 38 is compressed.

[0037] Furthermore, a lower pressure plate 39 is welded on the outer peripheral wall of the press-fitting rod 15, and a mounting bracket 40 is welded on the top of the main shell body 2. A press rod 41 is slidably arranged on the top of the mounting bracket 40, and a sleeve 42 is slidably arranged at the bottom of the press rod 41. A tooth block 44 is welded at the bottom of the sleeve 42, and a snap-in gear 45 meshing with the tooth block 44 is welded on the outer peripheral wall of the first rotating rod 4. When the mounting rod moves downward, the lower pressure plate 39 will be driven downward, and the lower pressure plate 39 will drive the press rod 41, the sleeve 42 and the tooth block 44 to move downward, so that the tooth block 44 is meshed with the snap-in gear 45. A spring three 43 is wound around the outer peripheral wall of the press rod 41, and the spring three 43 is connected between the sleeve 42 and the mounting bracket 40. The press-fitting rod 15 continues to move downward, and the set spring three 43 is compressed, thereby making the tooth block 44 and the snap-in gear 45 mesh more tightly.

[0038] Working principle: When in use, the worker places the reducer housing 53 on the top of the main housing 2, and then the worker twists the first rotating rod 4. It should be noted that the middle part of the first rotating rod 4 is a spiral pattern that meshes with the worm gear 6, and the end of the first rotating rod 4 is a spiral pattern that meshes with the internal threaded tube 11; the rotating first rotating rod 4 drives the worm gear 6 to rotate, and the worm gear 6 drives the second rotating rod 5 to rotate, and the second rotating rod 5 drives the disc to rotate. Since the curvature of the curved groove 8 on the disc gradually shrinks toward the center of the disc, and the bottom of the vertical rod 9 is slidably set in the curved groove 8, the rotating disc will push several vertical rods 9 to shrink toward the center of the main housing 2, and then the vertical rod 9 drives the clamping block 10 to abut against the outer wall of the reducer housing 53, so that the reducer housing 53 remains stable on the top of the main housing 2;

[0039] At the same time, the first rotating rod 4 drives the internal threaded tube 11 to move away from the main housing 2, and the inner housing drives the vertical plate 12 to move away from the main housing 2. Since the end of the first rack 16 is slidably arranged in the T-slot 13 on the outer wall of the vertical plate 12, the vertical plate 12 drives the first rack 16 to move away from the press-fitting rod 15. Since the first rack 16 is meshed with the third gear 18, the moving first rack 16 drives the third gear 18 to rotate, and the rotating third gear 18 drives the third rotating rod 17 to rotate, and the third rotating rod 17 mobilizes the gear ring 19 to rotate. Since the gear ring 19 is connected with a plurality of cones, The gears 21 are all meshed and connected, so that the rotating ring gear 19 will drive several bevel gears 21 to rotate synchronously, and the rotating bevel gear 21 will drive the first threaded rod 20 to rotate, and the rotating first threaded rod 20 drives the threaded block 22 to move toward the center of the press-fitting rod 15, and the threaded block 22 drives the connecting rod and the press-fitting shell 24 to shrink into the inner cavity of the press-fitting rod 15; this device relies on the synchronous shrinkage of several clamping blocks 10 and several press-fitting shells 24, so that when several clamping blocks 10 complete the clamping and fixing of the reducer housing 53, the press-fitting plane formed by the shrunk several press-fitting shells 24 and the bottom of the press-fitting rod 15 can just cover the reducer Most of the areas near the center of the inner cavity of the shell 53 make it unnecessary for workers to manually move the reducer shell 53 to align the bearing with the press-fitting rod 15. It should be noted that since the transmission gear needs to be installed on the bearing of the reducer, the bearing of the reducer is usually not installed in the edge area of ​​the inner cavity of the reducer shell 53; then the electric telescopic rod 14 drives the press-fitting plane formed by the press-fitting rod 15 and several press-fitting shells 24 to move downward, and then press-fit the bearing pre-placed at the bottom of the inner cavity of the reducer shell 53 into the groove body. Since the press-fitting plane formed by the press-fitting rod 15 and several press-fitting shells 24 completely covers the top of the bearing, it is not easy for the bearing to fall out after assembly. In addition, the press-fitting plane formed by the press-fitting rod 15 and the plurality of press-fitting shells 24 can also synchronously press-fit the two bearings in a horizontal state at the bottom of the inner cavity of the reducer housing 53, thereby improving the assembly efficiency; in addition, when the press-fitting rod 15 moves downward, it will drive the lower pressing plate 39 to move downward, and the lower pressing plate 39 will drive the press rod 41, the sleeve 42 and the tooth block 44 to move downward, so that the tooth block 44 is meshed with the clamping gear 45, and then the press-fitting rod 15 continues to move downward, and the set spring three 43 is compressed, so that the tooth block 44 is more closely meshed with the clamping gear 45, so as to reduce the probability of the first rotating rod 4 loosening due to the vibration generated during the subsequent assembly of the bearing;

[0040] like Fig.11As shown, when several press-fit shells 24 are synchronously contracted, the gap between two adjacent press-fit shells 24 gradually decreases, and the auxiliary pressure block 37 follows the press-fit shell 24 to move toward the inner cavity of the press-fit rod 15. At this time, the auxiliary pressure block 37 enters the interior of the assembly shell under the action of the cavity wall of the press-fit rod 15, and the spring 2 38 is compressed. On the contrary, when several press-fit shells 24 are synchronously expanded, the gap between two adjacent press-fit shells 24 gradually increases, and the auxiliary pressure block 37 follows the press-fit shell 24 to move toward the outside of the press-fit rod 15. At this time, the auxiliary pressure block 37 is displaced out of the inner cavity of the press-fit shell 24 under the elastic force of the spring 2 38, so as to fill the gap between two adjacent press-fit shells 24 and avoid the large gap affecting the assembly of the bearing. Since several clamping blocks 10 and several press-fit shells 24 can be synchronously contracted and expanded, and the auxiliary pressure block 37 can also contract and expand following the movement of the press-fit shell 24, the device can assemble the reducer housing 53 within a certain size range, thereby expanding the scope of use of the device;

[0041] In addition, since the reaction force applied by the bearing to the press-fit shell 24 is relatively large when the press-fit shell 24 is pressed downward, the connection between the press-fit shell 24 and the connecting block 23 tends to bend and break. When the connection between the press-fit shell 24 and the connecting block 23 tends to bend and break, the set press-fit shell 24 will drive the push rod 35 to move upward, and the push rod 35 will push the push plate 30 and the second rack 29 to move upward. The second rack 29 will drive the second gear 32 and the second threaded rod 31 to rotate, and the second threaded rod 31 will drive the threaded plate 33 and the extrusion plate 34 to move horizontally in the direction of the connecting block 23. Since the contact surface between the extrusion plate 34 and the press-fit shell 24 is an inclined surface abutting each other, the horizontally moving extrusion plate 34 will apply a force to the press-fit shell 24, thereby offsetting a part of the reaction force applied by the bearing to the press-fit shell 24, thereby reducing the risk of bending and breaking at the connection between the press-fit shell 24 and the connecting block 23.

[0042] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
