Description

Technical Field

[0001] This invention relates to an assembly stand, specifically a planetary gearbox assembly stand. Background Technology

[0002] Planetary gear reducers mainly consist of a housing, bearings, input shaft, planetary gears, sun gear, and internal gear ring. They are a widely used industrial product that can reduce motor speed while increasing output torque. Planetary gear reducers can be used as supporting components in industries such as lifting, excavation, transportation, and construction.

[0003] Currently, when assembling the bearings and input shafts of planetary reducers, the inner ring of the bearing is interference-fitted with the input shaft. Therefore, assembly is usually completed by tapping with a copper rod. However, it is difficult to control the steady force of the tapping, and mistakes can easily damage the bearings, resulting in unnecessary losses. At the same time, it also requires high operator skills, which is not conducive to improving the assembly efficiency of planetary reducers.

[0004] In view of this, a planetary reducer assembly stand that is simple to operate and easy to install is proposed to solve the above-mentioned technical problems. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology, such as the difficulty in operating and controlling the installation of bearings and input shafts on planetary reducers, and the high requirements for personnel operation skills, the purpose of this invention is to provide a planetary reducer assembly stand that is simple to operate and easy to install.

[0006] The technical solution is as follows: A planetary reducer assembly stand includes an assembly stand, an adjusting seat, a support, a guide rod, a pressing component, an elastic component, and a locking component. An adjusting seat is provided on the upper rear side of the assembly stand. A height-adjustable support is threaded through the adjusting seat. A locking component for fixing the support is threaded through the rear of the adjusting seat. A guide rod is provided on the top front side of the support. A pressing component that can slide up and down is sleeved on the guide rod, and the pressing component passes downward through the support. An elastic component is sleeved on the guide rod, and the upper and lower ends of the elastic component abut against the support. The extrusion component and support also include a pressure rod, a spur gear, a spiral spring, an extrusion assembly, and a pushing assembly. The pressure rod is rotatably mounted on the top of the support through two connecting blocks, and the connecting blocks are located on the rear side of the extrusion component. A spur gear is fitted on the pressure rod, and rotating the spur gear can drive the extrusion component to slide up and down. A spiral spring is provided between the pressure rod and the connecting blocks. An extrusion assembly for assembling with an auxiliary planetary reducer is provided at the lower part of the extrusion component. A pushing assembly for intermittently pressing the extrusion assembly is provided between the support and the pressure rod.

[0007] Furthermore, the extrusion assembly includes a pressure ring, a fixing ring, and a reset member. The fixing ring is sleeved in the middle of the extrusion assembly, and the pressure ring is provided at the lower part of the extrusion assembly. The pressure ring and the fixing ring are connected by a reset member, which is sleeved on the outside of the extrusion assembly, and the extrusion assembly can pass through the pressure ring.

[0008] Furthermore, the pushing assembly includes guide sleeves, slide rods, compression seats, and dials. Two guide sleeves are provided on the upper front side of the support. Each guide sleeve is fitted with a slide rod that can slide up and down, and the lower ends of the two slide rods are connected to the pressure ring. Compression seats are provided on the upper ends of the two slide rods respectively. Two dials are fitted on the pressure rod. The two dials are located on the outside of the connecting block. When the dials rotate, they can contact the adjacent compression seats, so that the slide rod can slide downwards to compress the pressure ring.

[0009] Furthermore, the extrusion component is mainly composed of a rack and an extrusion column. The rack is slidably mounted on the upper part of the guide rod and meshes with the spur gear. The lower end of the rack is fixedly connected to the extrusion column, and the extrusion column slidably passes through the support.

[0010] Furthermore, it also includes a height adjustment device, which includes a fixed rod, a connecting seat, a threaded rod, and a handwheel. The fixed rod is provided on the upper left rear side of the assembly platform, and the threaded rod is rotatably provided on the upper right rear side of the assembly platform. Connecting seats are provided on both the left and right sides of the upper part of the support. The connecting seat on the left side is slidably sleeved with the fixed rod, and the connecting seat on the right side is screwed into the threaded rod. A handwheel is connected to the top of the threaded rod.

[0011] Furthermore, it also includes a mounting frame, a rotating shaft, a worm gear, a large bevel gear, a rotating rod, a worm, a turntable, a lead screw, a small bevel gear, and an extrusion frame. The mounting frame is located at the top of the assembly platform. A rotating shaft is rotatably mounted in the middle of the mounting frame. A worm gear is fitted onto the lower part of the rotating shaft, and a large bevel gear is fitted onto the upper part of the rotating shaft. A rotating rod is rotatably mounted on the front side of the mounting frame. A worm is fitted onto the rear part of the rotating rod, and the worm meshes with the worm gear. A turntable is located at the front end of the rotating rod. Four lead screws are rotatably mounted on the top of the assembly platform via mounting seats. The four lead screws are evenly spaced along the circumference of the large bevel gear. Small bevel gears are fitted onto the ends of the four lead screws that are close to each other, and the small bevel gears mesh with the large bevel gears. An extrusion frame is threaded onto each lead screw. The assembly platform has a groove for accommodating the extrusion frame, and the extrusion frame can move horizontally along the groove.

[0012] Furthermore, it also includes pads, with pads provided at the upper, close-to-each ends of the extrusion frame.

[0013] Furthermore, it also includes a positioning plate, which is embedded in the middle of the top of the assembly stand and is located directly below the extruded part.

[0014] Furthermore, it also includes an adjusting block and a limiting rod. An adjusting block is provided on the rear side of the top of the support, and a limiting rod for adjusting the reset angle of the pressure rod is passed through the adjusting block.

[0015] Furthermore, the adjusting block has multiple adjusting holes along the vertical direction, and one end of the limiting rod is inserted into the adjusting holes.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. By rotating the pressure rod, the spur gear can drive the pressing component to slide downwards and press the input shaft on the planetary reducer. At the same time, the dial rotates to intermittently push the pressing seat, which in turn allows the slide rod to drive the pressure ring to slide up and down intermittently, so as to achieve the purpose of intermittently and smoothly pushing the bearing on the planetary reducer. Through the dual pressing action of the pressing component and the pressure ring, it is more conducive to the smooth assembly of the input shaft and bearing on the planetary reducer.

[0018] 2. The height of the support can be easily adjusted by turning the handwheel, which is beneficial for assembling different models of planetary reducers and has a wide range of applications.

[0019] 3. Rotating the turntable can drive the worm gear, worm wheel, and large bevel gear to rotate synchronously, which in turn drives the small bevel gear and lead screw to rotate, so that the four extrusion frames can synchronously retract towards the center along the slide groove, thereby achieving the purpose of clamping different models of planetary reducer housings. This can improve the stability of planetary reducer assembly and thus further improve the assembly efficiency of planetary reducers. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] See Figures 1-5As shown, the planetary reducer assembly stand proposed in this invention includes an assembly stand 1, an adjusting seat 2, a support 3, a guide rod 4, an extrusion component 5, an elastic component 6, a pressure rod 7, a spur gear 8, a spiral spring 9, a locking component 100, an extrusion assembly, and a pushing assembly. An adjusting seat 2 is provided on the upper rear side of the assembly stand 1. A height-adjustable support 3 is threaded through the adjusting seat 2. A locking component 100 is threaded through the rear of the adjusting seat 2, used to lock and fix the support 3 after it has been adjusted to the correct position. A guide rod 4 is provided on the top front side of the support 3. An extrusion component 5, which can slide up and down, is sleeved on the guide rod 4. The extrusion component 5 mainly consists of a rack and an extrusion column. The rack is slidably fitted onto the upper part of the guide rod 4 and meshes with the spur gear 8. An extrusion column is fixedly connected to the lower end of the rack, and the extrusion column slidably passes through the support. 3. An elastic element 6 is sleeved on the guide rod 4. The upper and lower ends of the elastic element 6 abut against the extrusion member 5 and the support 3, respectively. The elastic element 6 is a compression spring. A pressure rod 7 is rotatably inserted through two connecting blocks at the top of the support 3. The connecting blocks are located on the rear side of the extrusion member 5. The pressure rod 7 has an L-shaped structure. A spur gear 8 is sleeved on the pressure rod 7. Rotating the spur gear 8 can drive the extrusion member 5 to slide up and down. A spiral spring 9 is provided between the pressure rod 7 and the connecting blocks to reset the pressure rod 7 after it has been flipped. An extrusion assembly is provided at the lower part of the extrusion member 5. The extrusion assembly is used to assist the planetary reducer in smooth assembly. A pushing assembly is provided between the support 3 and the pressure rod 7. The pushing assembly is used to intermittently press the extrusion assembly to achieve the purpose of smoothly tapping and pushing the bearings on the planetary reducer.

[0031] For further details, please refer to [link / reference]. Figure 1 and Figure 5 As shown, the extrusion assembly includes a pressure ring 10, a fixing ring 11, and a reset member 12. The fixing ring 11 is sleeved in the middle of the extrusion member 5, and the pressure ring 10 is provided at the lower part of the extrusion member 5. The pressure ring 10 and the fixing ring 11 are connected by the reset member 12. The reset member 12 is also a compression spring, which can buffer the pressure ring 10. The reset member 12 is sleeved on the outside of the extrusion member 5, and the extrusion member 5 can pass through the center of the pressure ring 10.

[0032] For further details, please refer to [link / reference]. Figure 1 , Figure 2 and Figure 5As shown, the pushing assembly includes a guide sleeve 13, a slide rod 14, a pressing seat 15, and a dial 16. Two guide sleeves 13 are provided on the upper front side of the support 3. Each of the two guide sleeves 13 is provided with a slide rod 14 that can slide up and down. The lower ends of the two slide rods 14 are connected to the pressure ring 10. The upper ends of the two slide rods 14 are respectively provided with pressing seats 15. Two dials 16 are sleeved on the pressure rod 7. The two dials 16 are respectively located on the outside of the connecting block. When the dials 16 rotate, they can contact the adjacent pressing seats 15, so that the slide rods 14 can slide down to press the pressure ring 10.

[0033] Place the planetary reducer housing to be assembled on top of the assembly stand 1, directly below the extrusion piece 5. Pull the pressure rod 7 counterclockwise. Driven by the spur gear 8, the extrusion piece 5 slides downward. Simultaneously, the pressure ring 10 slides downward, allowing it to move down before the extrusion piece 5. This allows the pressure ring 10 and the extrusion piece 5 to press the bearings and input shaft on the planetary reducer, respectively, achieving the purpose of smoothly pressing the bearings and input shaft into the planetary reducer housing. Furthermore, the rotation of the pressure rod 7 also drives the dial 16 to rotate synchronously, allowing the dial 16 to... The compression seat 15 can be intermittently pressed downwards, thereby causing the pressure ring 10 to slide up and down intermittently, so as to achieve the purpose of intermittently and smoothly pushing the bearings on the planetary reducer, which is conducive to the smooth assembly of the planetary reducer and makes the operation more convenient. In this way, through the dual compression action of the compression component 5 and the pressure ring 10, the planetary reducer can be assembled more smoothly, which is conducive to improving the assembly efficiency of the planetary reducer. When the pressure rod 7 is released, the elastic force of the elastic component 6 and the spiral spring 9 can drive the components on them to reverse and reset.

[0034] Example 2: Based on Example 1, such as Figure 1 , Figure 2 and Figure 6 As shown, it also includes a height adjustment device, which includes a fixed rod 17, a connecting seat 18, a threaded rod 19, and a handwheel 20. The fixed rod 17 is provided on the upper left rear side of the assembly platform 1, and the threaded rod 19 is rotatably provided on the upper right rear side of the assembly platform 1. The connecting seats 18 are provided on both the left and right sides of the upper part of the support 3. The connecting seat 18 on the left side is slidably sleeved with the fixed rod 17, and the connecting seat 18 on the right side is screwed into the threaded rod 19. The top of the threaded rod 19 is connected to the handwheel 20. Rotating the handwheel 20 can drive the threaded rod 19 to rotate, thereby driving the support 3 to adjust its height upward or downward through the connecting seat 18. This is beneficial for assembling different models of planetary reducers, and the operation is simple and convenient.

[0035] When the height of the support 3 needs to be adjusted, first loosen the locking part 100, then turn the handwheel 20 to drive the threaded rod 19 to rotate, so that the support 3 and its components can be raised or lowered through the connecting seat 18. After the height of the support 3 is adjusted, tighten the locking part 100. In this way, the height of the support 3 can be easily adjusted by turning the handwheel 20, which is convenient for assembling different models of planetary reducers, has a wide range of applications, and is highly practical.

[0036] Example 3: Based on Example 2, such as Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, the assembly platform 1 also includes a mounting frame 21, a rotating shaft 22, a worm gear 23, a large bevel gear 24, a rotating rod 25, a worm 26, a turntable 27, a lead screw 28, a small bevel gear 29, and an extrusion frame 30. The mounting frame 21 is located at the top of the assembly platform 1. A rotating shaft 22 is rotatably mounted in the middle of the mounting frame 21. A worm gear 23 is fitted onto the lower part of the rotating shaft 22, and a large bevel gear 24 is fitted onto the upper part of the rotating shaft 22. A rotating rod 25 is rotatably mounted on the front side of the mounting frame 21. A worm 26 is fitted onto the rear part of the rotating rod 25, and the worm 26 meshes with the worm gear 23. A turntable 27 is located at the front end of the rotating rod 25. Rotating the turntable 27 drives the worm 26 and the worm gear 23 to rotate synchronously. Four lead screws 28 are rotatably mounted on the inner top of the assembly stand 1 via mounting bases. The four lead screws 28 are evenly spaced along the circumference of the large bevel gear 24. Small bevel gears 29 are fitted onto the ends of the four lead screws 28 that are close to each other, and the small bevel gears 29 mesh with the large bevel gears 24 respectively. Each lead screw 28 is threadedly fitted with a pressing frame 30. The assembly stand 1 has a sliding groove 32 for accommodating the pressing frame 30, and the pressing frame 30 can move horizontally along the sliding groove 32. When the four lead screws 28 drive the pressing frame 30 on them to retract synchronously towards the center, the planetary reducer can be clamped and limited, and it can be used to clamp different models of planetary reducers.

[0037] Furthermore, such as Figure 7 and Figure 8 As shown, it also includes pads 31. Each of the upper ends of the extrusion frame 30 that are close to each other is provided with pads 31, which can increase the coefficient of friction and thus help to enhance the clamping force on the planetary reducer.

[0038] Furthermore, such as Figure 1 , Figure 2 and Figure 7As shown, it also includes a positioning disk 33. The positioning disk 33, which can be rotated, is embedded in the middle of the top of the assembly stand 1, and the positioning disk 33 is located directly below the extrusion piece 5, which facilitates the rotation and adjustment of the orientation of the planetary reducer housing.

[0039] In addition, such as Figure 2 and Figure 4 As shown, it also includes an adjusting block 34 and a limiting rod 35. An adjusting block 34 is provided on the rear side of the top of the support 3. A limiting rod 35 for adjusting the reset angle of the pressure rod 7 is passed through the adjusting block 34. The adjusting block 34 has multiple adjusting holes along the vertical direction. One end of the limiting rod 35 is inserted into the adjusting hole, which is beneficial for adjusting the reset angle of the pressure rod 7.

[0040] The planetary reducer housing is placed on the positioning plate 33. The position of the planetary reducer housing can be adjusted by rotating the positioning plate 33. By rotating the turntable 27, the worm gear 26 can drive the worm wheel 23 and the large bevel gear 24 to rotate, which in turn drives the small bevel gear 29 and the lead screw 28 to rotate. This allows the extrusion frame 30 to retract and clamp the planetary reducer housing, thereby achieving the purpose of limiting the position of the planetary reducer housing and preventing shaking during the assembly of the bearings and input shaft. This is more conducive to improving the assembly efficiency of the planetary reducer.
