[0035] The following will be combined with the attached Figure 1-10 The present invention is described in detail, and the technical solutions in the embodiments of the present invention are clearly and completely described. 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 1-10 The fully automatic assembly equipment of a speed reducer of the present invention comprises a processing table 1, and a rotating shaft feeding rack 5 and a gear feeding rack 6 are sequentially arranged on one side of the surface of the processing table 1;

[0037] A fixed disk 8 is fixedly connected to the upper surface of the processing table 1, and a rotating disk 7 is rotatably connected above the fixed disk 8. An assembly component 2 is arranged on the side of the processing table 1 near the gear feed rack 6. The assembly component 2 includes a press cylinder 21 installed above the gear feed rack 6 and a fixed seat 25 fixedly connected to the output end of the press cylinder 21. A pressing cylinder 27 is arranged inside the fixed seat 25, and a pressing cylinder 27 is installed between the pressing cylinder 27 and the fixed seat 25. A sliding rod 213 is symmetrically fixedly connected inside the fixed seat 25. A connecting clamp 214 is slidably sleeved on one side of the sliding rod 213 close to the pressing cylinder 27, and a connecting clamp 214 is slidably sleeved on one side of the sliding rod 213 away from the clamp 214. The movable block 211 is slidably connected to the end, and a first spring 216 is fixedly connected between the movable block 211 and the slide bar 213, and the first spring 216 is sleeved on the surface of the slide bar 213. The side of the movable block 211 is symmetrically hinged with a second push rod 217, and the fixed seat 25 is symmetrically slidably connected to the first push rod 210 in a U-shaped structure. A protrusion 28 is fixedly connected to the side of the rotating shaft feeding frame 5 close to the first push rod 210, and a clamping rod 219 is fixedly connected to the inner side of the first push rod 210, and the clamping rod 219 is slidably inserted in the second push rod 217. A clamping groove 218 is provided on the bottom surface of the movable block 211 close to the clamping rod 219.

[0038] The rotating shaft feeding rack 5 and the gear feeding rack 6 are both connected to the silo, and the rotating shaft feeding rack 5 and the gear feeding rack 6 are both provided with conveyor belts or conveyor rollers inside, which can transport the rotating shaft and the gear. When the gear and the rotating shaft need to be assembled, the fixing seat 25 is pushed downward by starting the press cylinder 21, so that the first push rod 210 is released from the protrusion 28. As the fixing seat 25 moves downward, the first push rod 210 moves upward under the reaction force, and pushes the movable block 211 on the surface of the sliding rod 213 through the second push rod 217, squeezing the clamping plate 214, and clamping the gear on the gear feeding rack 6 through the two sets of clamping plates 214. At the same time, the first The movement of the push rod 210 will drive the clamping rod 219 to slide into the clamping groove 218, positioning the position of the movable block 211, so that the clamping plate 214 clamps and locks the gear, which is convenient for moving the gear. The gear is moved above the rotating shaft, and the pressing cylinder 21 is started to press the gear onto the rotating shaft through the pressing barrel 27. The pressing force data can be fed back in time through the pressure sensor 26, and the pressure on the gear can be monitored in real time, which is convenient for accurately controlling the pressing pressure and ensuring the stability of the assembly. The pressure of the movable block 211 can be buffered by the first spring 216, and at the same time, the clamping plate 214 can fix different gears within a certain size range.

[0039] A sliding groove is provided on one side of the second push rod 217 near the locking rod 219, and a second spring 220 is provided inside the sliding groove, and the two ends of the second spring 220 respectively conflict with the locking rod 219 and the second push rod 217; during the upward movement of the first push rod 210, the locking rod 219 will be pushed to slide in the sliding groove and squeeze the second spring 220 to contract. When the locking rod 219 slides into the locking groove 218, the upward thrust of the first push rod 210 is perpendicular to the elastic force of the second spring 220, so that the locking rod 219 is pressed against the inner wall of the locking groove 218 by the elastic force of the second spring 220, thereby improving the stability of the limit of the movable block 211.

[0040] A docking rod 212 is symmetrically fixedly connected inside the fixed seat 25, and a second limiting cylinder 29 matching the docking rod 212 is symmetrically fixedly connected on the upper surface of the protrusion 28. A plurality of groups of first limiting cylinders 22 in a ring array and matching the docking rod 212 are fixedly connected on the upper surface of the rotating disk 7. When the fixed seat 25 moves downward, the docking rod 212 will dock with the second limiting cylinder 29 and be inserted into the second limiting cylinder 29. The guide limit of the second limiting cylinder 29 ensures that the gear is aligned with the pressing cylinder 27, thereby improving the accuracy of gear positioning. When the gear is pressed, the docking rod 212 will align with the first limiting cylinder 22 on both sides of the assembly shaft, and the docking rod 212 will slide into the first limiting cylinder 22 to guide the downward pressure of the fixed seat 25, thereby ensuring the accuracy of gear pressing.

[0041] A lever 221 is hinged on one side of the first push rod 210 near the slot 218; a rubber pad 215 with an arc-shaped structure is fixedly connected to the bottom end of the clamping plate 214, and the height of the first limiting cylinder 22 is higher than that of the second limiting cylinder 29. During the downward pressing process of the fixing seat 25, the first limiting cylinder 22 slides on the surface of the docking rod 212. As the fixing seat 25 moves, the first limiting cylinder 22 pushes the lever 221 to flip, so that the lever 221 pushes the locking rod 219 out of the slot 218, thereby releasing the clamping plate 214 from fixing the gear, making it easier to separate the fixing seat 25 from the gear after assembly.

[0042] The upper surface of the fixing seat 25 is symmetrically fixedly connected with a first guide rod 24 , and both sides of the press-fitting cylinder 21 are symmetrically fixedly connected with a first fixing block 23 , and the first guide rod 24 slides inside the first fixing block 23 .

[0043] A conveying assembly 3 is provided on one side of the processing table 1 surface close to the press-fitting cylinder 21. The conveying assembly 3 includes a fixing frame 32 fixed on the processing table 1 above the press-fitting cylinder 21. An electric push rod 31 is installed on the side of the fixing frame 32. The output end of the electric push rod 31 is fixedly connected to a mounting seat 33, and the press-fitting cylinder 21 is installed on the surface of the mounting seat 33. A second guide rod 34 is symmetrically fixedly connected to the surface of the fixing frame 32, and the mounting seat 33 is slidably sleeved on the surface of the second guide rod 34.

[0044] After the gear is fixed, the mounting seat 33 is pushed toward the side of the rotating disk 7 by starting the electric push rod 31, so that the gear is moved to be aligned above the rotating shaft, and the fixing seat 25 is moved to the processing station on the rotating disk 7 to complete the feeding and conveying of the gear, which is convenient for the subsequent assembly of the gear and the rotating shaft. When the mounting seat 33 moves, it will slide on the surface of the second guide rod 34, and the second guide rod 34 is limited to improve the stability of the movement of the press cylinder 21.

[0045] The surface of the fixed disk 8 is provided with a positioning assembly 4, which includes a track groove 41 opened inside the fixed disk 8, a placement groove 43 is opened on the side of the surface of the rotating disk 7 close to the first limiting cylinder 22, a limiting clamping plate 42 with a U-shaped structure is fixedly connected to the side of the bottom surface of the rotating disk 7 close to the placement groove 43, and a feeding groove is opened on the side of the surface of the fixed disk 8 close to the rotating shaft feeding frame 5; the cross section of the track groove 41 is T-shaped, and a plurality of groups of rollers 44 are rotatably connected to the side of the fixed disk 8 close to the track groove 41;

[0046] When loading the shaft, the shaft is transported by the shaft feeding rack 5, and then the shaft slides into the track groove 41 along the feeding trough, and at the same time, the shaft is limited by the limiting clamping plate 42 to complete the loading of the shaft. A driving motor is installed inside the processing table 1, and the output end of the motor is connected to the rotating disk 7. By starting the motor to drive the rotating disk 7 to rotate, it is convenient to move the shaft to the assembly station, thereby improving the work efficiency of the shaft and gear pressing. By setting the track groove 41, the wear of the shaft and the fixed disk 8 during the shaft transportation can be reduced.

[0047] Finally, it should be noted that the above are only preferred embodiments of the present invention and are 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. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
