Description

Technical Field

[0001] This utility model discloses a direction selection mechanism for a planetary gear housing, belonging to the technical field of direction selection mechanism. Background Technology

[0002] Planetary gears are a commonly used speed reduction mechanism. A planetary gear typically includes a gear housing and several planetary gears rotatably connected to the gear housing. The outer circumference of the gear housing has mounting slots for the planetary gears to enter. During assembly, the planetary gears need to be installed into the mounting slots of the gear housing, and then pins are used to connect the planetary gears and the gear housing, forming a rotatable connection. However, during the assembly of the planetary gears and the gear housing, the orientation of the gear housing must first be selected so that the mounting slots are aligned with the assembly positions of the planetary gears, allowing the planetary gears to be quickly pushed into the mounting slots. Currently, the orientation selection of the gear housing requires manual operation, which increases labor costs, prevents fully automated assembly, and reduces the assembly efficiency of the planetary gears. Utility Model Content

[0003] The purpose of this invention is to solve the problem that the orientation selection of the housing needs to be done manually, which increases labor costs and reduces assembly efficiency. To this end, an orientation selection mechanism for planetary gear housing is provided, which can automatically select the orientation of the housing without manual operation, thus helping to improve the assembly efficiency of planetary gears.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A direction selection mechanism for a planetary gear housing is disclosed. The housing has several mounting slots and pin holes penetrating the mounting slots axially. The planetary gears are assembled into the mounting slots through the engagement of the pin shafts and the pin holes. The direction selection mechanism includes a frame, a rotating platform on which the housing is placed and rotated, a detection mechanism for detecting the position of the housing, and a positioning mechanism for positioning the housing. The detection mechanism includes an upper ejector and a lower ejector located above the rotating platform. The upper and lower ejectors pass through the pin holes to perform firing to achieve preliminary positioning of the housing. The positioning mechanism includes a positioning driver and a positioning block. The positioning block is adapted to the mounting slots, and the positioning driver controls the positioning block to insert into the mounting slots to achieve positioning of the housing.

[0006] The beneficial effects of using this utility model are:

[0007] The frame of this invention is equipped with a rotating platform, a detection mechanism, and a positioning mechanism. The outer casing is placed on the rotating platform, and the rotation of the platform causes the outer casing to rotate. The detection mechanism includes an upper and a lower transmitter, which can transmit signals to each other. When there is no obstruction between the upper and lower transmitters, they can receive signals from each other and complete the signal transmission. As the outer casing rotates, when the pin hole is above the upper transmitter, the signals transmitted by the upper and lower transmitters can pass through the pin hole of the outer casing, thus forming a signal transmission, indicating that the orientation of the outer casing has been initially determined. At this point, the detection mechanism can transmit the completed signal transmission. The initial positioning signal is generated, which controls the rotary table to stop rotating. Then, the positioning driver drives the positioning block to move towards the housing and inserts the positioning block into the mounting slot of the housing. Since the positioning block is compatible with the mounting slot, the positioning block can make a final adjustment to the orientation of the housing after it is inserted into the mounting slot, thereby completing the selection of the housing orientation. After the orientation is selected, the housing can be placed into the subsequent process through the feeding mechanism. The orientation selection mechanism can automatically complete the orientation selection of the housing without manual operation, which can save labor costs and realize fully automatic assembly of planetary gears, which can significantly improve the assembly efficiency of planetary gears.

[0008] Preferably, the rotary table has an axially penetrating through-hole, and the top of the rotary table has a positioning step for positioning the housing. The lower transmitter is fixed to the lower side of the rotary table, and the signal emitted by the lower transmitter passes through the pin hole of the housing along the through-hole. Using the aforementioned technical solution, the through-hole of the rotary table can avoid the signal emission of the lower transmitter, preventing the rotary table from obstructing the transmission path of the lower transmitter, and ensuring that the upper and lower transmitters can receive signals from each other and complete the signal exchange.

[0009] Preferably, the detection mechanism further includes a translation driver, which is fixed to the frame and used to drive the upper through-beam to move closer to or away from the housing. Using the aforementioned technical solution, the translation driver can move the upper through-beam away from the top of the housing, facilitating the loading or unloading of the housing and improving the efficiency of selecting the housing orientation.

[0010] Preferably, the detection mechanism further includes a lifting driver, the output end of which is provided with a positioning component. The positioning component includes a positioning shaft. The lifting driver drives the positioning shaft to descend and engage with the shaft hole in the middle of the housing to assist the rotation of the housing. The upper through-beam is fixed to the positioning component. By adopting the aforementioned technical solution, positioning through the positioning shaft and the shaft hole of the housing can ensure that the positions of the upper and lower through-beams remain aligned. At the same time, the positioning shaft can also make the rotation of the housing more stable and prevent the housing from detaching from the rotating table during rotation.

[0011] Preferably, the housing has three mounting slots and three pin holes, and the detection mechanism includes three upper and three lower probes. The arrangement of the upper and lower probes corresponds to the arrangement of the pin holes on the housing. The three lower probes pass through the pin holes simultaneously and form a counter-beam with the three upper probes to achieve the initial positioning of the housing.

[0012] Preferably, the positioning mechanism includes three positioning blocks and three positioning drivers. The three positioning blocks are radially distributed on the outer periphery of the rotary table. The positioning drivers drive the positioning blocks to slide along the radial direction of the rotary table. The three positioning blocks are simultaneously inserted into the mounting slots of the housing to achieve the positioning of the housing.

[0013] Preferably, the end of the positioning block is provided with a clearance hole for avoiding the pin hole.

[0014] Preferably, the frame is equipped with a sensing device for detecting whether the rotating platform is covered by a housing.

[0027] like Figures 1 to 6As shown in the figure, this embodiment illustrates a direction selection mechanism for a planetary gear housing 7. The housing 7 is provided with several mounting slots 71 and pin holes 72 that penetrate the mounting slots 71 in the axial direction. The planetary gears are assembled into the mounting slots 71 through the engagement of the pin shaft and the pin hole 72. The direction selection mechanism includes a frame 1, on which a rotating platform 2 is provided for placing the housing 7 and driving the housing 7 to rotate, a detection mechanism 3 for detecting the position of the housing 7, and a positioning mechanism 4 for positioning the housing 7. The detection mechanism 3 includes an upper shot 34 located on the upper side of the rotating platform 2 and a lower shot 35 located on the lower side of the rotating platform 2. The upper shot 34 and the lower shot 35 pass through the pin hole 72 to shoot at each other to achieve the initial positioning of the housing 7. The positioning mechanism 4 includes a positioning driver 41 and a positioning block 42. The positioning block 42 is adapted to the mounting slots 71. The positioning driver 41 controls the positioning block 42 to insert into the mounting slots 71 to achieve the positioning of the housing 7.

[0028] In this embodiment, the frame 1 is equipped with a rotating platform 2, a detection mechanism 3, and a positioning mechanism 4. The outer casing 7 is placed on the rotating platform 2. The rotation of the rotating platform 2 drives the outer casing 7 to rotate. The detection mechanism 3 includes an upper transmitter 34 and a lower transmitter 35. The upper transmitter 34 and the lower transmitter 35 can transmit signals to each other. When there is no obstruction between the upper transmitter 34 and the lower transmitter 35, they can receive signals from each other and complete the signal transmission. As the outer casing 7 rotates, when the pin hole 72 is above the upper transmitter 34, the signals transmitted by the upper transmitter 34 and the lower transmitter 35 can pass through the pin hole 72 of the outer casing 7, thus forming a signal transmission. That is, the orientation of the outer casing 7 has been initially positioned. At this time, the detection mechanism 3 can... The signal indicating that the initial positioning has been completed is transmitted to control the rotary table 2 to stop rotating. Then, the positioning driver 41 drives the positioning block 42 to move towards the housing 7 and inserts the positioning block 42 into the mounting slot 71 of the housing 7. Since the positioning block 42 is compatible with the mounting slot 71, the positioning block 42 can make a final adjustment to the orientation of the housing 7 after it is inserted into the mounting slot 71, thereby completing the selection of the orientation of the housing 7. After the orientation is selected, the housing 7 can be placed into the subsequent process through the feeding mechanism. The orientation selection mechanism can automatically complete the orientation selection of the housing 7 without manual operation, which can save labor costs and realize the fully automatic assembly of planetary gears, which can significantly improve the assembly efficiency of planetary gears.

[0029] like Figure 3 and Figure 6As shown, in this embodiment, the rotary table 2 is provided with an axially penetrating through hole 211. The top edge of the through hole 211 is provided with a positioning step 21 for positioning the housing 7. The housing 7 is placed on the rotary table 2 and embedded in the positioning step 21. The pin hole 72 of the housing 7 is aligned with the through hole 211 of the rotary table 2. The lower beam emitter 35 is fixed to the lower side of the rotary table 2. The signal emitted by the lower beam emitter 35 passes through the pin hole 72 of the housing 7 along the through hole 211. The through hole 211 of the rotary table 2 can avoid the signal emission of the lower beam emitter 35, and prevent the rotary table 2 from blocking the emission path of the lower beam emitter 35, so as to ensure that the upper beam emitter 34 and the lower beam emitter 35 can receive signals from each other and complete the beam emission.

[0030] like Figure 2 and Figure 3 As shown, the detection mechanism 3 in this embodiment further includes a translation driver 31 and a lifting driver 32. The translation driver 31 is fixed to the frame 1, and the output end of the translation driver 31 is provided with a fixed seat 311. The lifting driver 32 is fixedly connected to the fixed seat 311, and the output end of the lifting driver 32 is connected to a positioning member 33. A positioning shaft 331 is rotatably connected to the positioning member 33. The bottom end of the positioning shaft 331 has a tapered structure. The lifting driver 32 drives the positioning shaft 331 to descend and cooperate with the shaft hole 73 in the middle of the housing 7 to assist the rotation of the housing 7. The upper detector 34 is fixed to the positioning member 33. When the housing 7 is placed into the rotary table 2, the translation driver 31 drives the positioning member 33 to move to the top of the housing 7, and then the lifting driver 32 drives the positioning member 33 to descend, so that the positioning member 33 is fixed to the top of the housing 7. Positioning shaft 331 is inserted into shaft hole 73 of housing 7, so that positioning shaft 331 and shaft hole 73 of housing 7 are positioned. After positioning shaft 331 and housing 7 are positioned, the positions of upper and lower transmitters 34 and 35 are aligned. When housing 7 rotates with rotary table 2 until shaft hole 73 and lower transmitter 35 are aligned, the signals emitted by upper and lower transmitters 34 and 35 can pass through pin hole 72 of housing 7 to form a signal exchange. In addition, after positioning shaft 331 and housing 7 are positioned, positioning shaft 331 can also make the rotation of housing 7 more stable and prevent housing 7 from falling off rotary table 2 during rotation. Secondly, the translation driver 31 can move upper transmitter 34 away from the top of housing 7 to facilitate loading or unloading of housing 7 and help improve the selection efficiency of housing 7 direction.

[0031] like Figure 3 As shown, in this embodiment, a rotary motor 23 is provided on the lower side of the frame 1. The output shaft of the rotary motor 23 is fixed with a drive wheel 231. The rotary table 2 extends to the lower side of the frame 1. A driven wheel 22 is fixed at the bottom of the rotary table 2. The drive wheel 231 and the driven wheel 22 are connected by a synchronous belt 24. The rotary motor 23 transmits rotational power to the rotary table 2 through the transmission belt, thereby realizing the rotation of the rotary table 2.

[0032] In this embodiment, the outer casing 7 has three mounting slots 71 and three pin holes 72. The detection mechanism 3 includes three upper through-holes 34 and three lower through-holes 35. The arrangement of the upper through-holes 34 and lower through-holes 35 corresponds to the arrangement of the pin holes 72 on the outer casing 7. The three lower through-holes 35 pass through the pin holes 72 simultaneously and form through-holes with the three upper through-holes 34 to achieve the initial positioning of the outer casing 7.

[0033] like Figure 6 As shown, in this embodiment, the frame 1 is provided with a mounting platform 11, and the rotating platform 2 is rotatably disposed in the middle of the mounting platform 11. The positioning mechanism 4 includes a positioning driver 41 and a positioning block 42. The positioning driver 41 is fixed on the frame 1, and the output end of the positioning driver 41 is connected to the positioning block 42. The positioning block 42 is slidably mounted on the mounting platform 11, and the positioning driver 41 drives the positioning block 42 to reciprocate along the radial direction of the mounting platform 11. In addition, in this embodiment, the positioning mechanism 4 includes three positioning blocks 42 and three positioning drivers 41. The three positioning blocks 42 are radially distributed on the outer periphery of the rotating platform 2. The positioning driver 41 drives the positioning blocks 42 to slide along the radial direction of the rotating platform 2. The three positioning blocks 42 are simultaneously inserted into the mounting groove 71 of the outer shell 7 to achieve the positioning of the outer shell 7. In addition, in order to avoid the positioning blocks 42 interfering with the upper and lower through-beams 34 and 35, the end of the positioning block 42 in this embodiment is provided with a clearance hole 421 for avoiding the pin hole 72.

[0034] When the upper and lower photomasks 34 and 35 are aligned through the pin hole 72, the rotary motor 23 is turned off to stop the rotation of the turntable 2. At this time, the initial positioning of the housing 7 is completed. Then, the positioning driver 41 starts to control the positioning block 42 to slide toward the housing 7, so that the positioning block 42 is inserted into the mounting slot 71 of the housing 7. The positioning block 42 can form the final positioning of the housing 7, thereby completing the orientation selection of the housing 7.

[0035] like Figure 1 As shown, in this embodiment, the frame 1 is equipped with a sensing device 6 for detecting whether the outer shell 7 is used on the rotary table 2. The sensing device 6 can avoid repeatedly placing the outer shell 7 on the rotary table 2, ensuring that the orientation of the outer shell 7 is selected more orderly.
