Description

Technical Field

[0001] This utility model relates to a disassembly device, and more particularly to a device that can assist workers in efficiently disassembling motor end covers, belonging to the technical field of motor end cover disassembly equipment. Background Technology

[0002] The motor end cover is an important component of a motor, usually installed at the end of the motor to enclose the internal structure and components. During operation, when the motor needs maintenance or malfunction, the end cover needs to be removed to repair the internal structure. In actual production, the harsh working environment can cause the bolts connecting the end cover to the motor housing to be loosened, leaving the end cover stuck at the motor end. Currently, the solution for end covers that cannot be easily removed is to manually pry them open by striking the protrusions on the end cover with a pry bar or by pressing against the joint between the end cover and the motor. This damages the end cover itself, affecting its appearance and the tightness of the joint with the motor. Furthermore, manual disassembly is inefficient and labor-intensive. Therefore, a device is needed to assist workers in disassembling the end cover. Utility Model Content

A hole is provided at the end of the long rod away from the central column, and the sliding rod is inserted into this hole. A threaded hole is provided at the end of the long rod's sidewall away from the central column, and a positioning bolt passes through this threaded hole and presses against the sidewall of the sliding rod.

[0012] See Figure 1 , 2 and Figure 3 This utility model includes a central guide portion and a cap-removing portion; there are multiple cap-removing portions, all of which are disposed on the central guide portion; the central guide portion includes a first disc 1, a second disc 2, and a central column; the two ends of the central column are respectively connected to the center of the first disc 1 and the center of the second disc 2; the axis lines of the first disc 1, the second disc 2, and the central column coincide; annular guide strips are provided on the end faces of the first disc 1 and the second disc 2 that are close to each other.

[0013] The cap removal part includes a position adjustment mechanism, a drive mechanism, and a separation mechanism; the position adjustment mechanism is disposed between the first disk 1 and the second disk 2; the drive mechanism is disposed on the position adjustment mechanism; and the separation mechanism is disposed on the drive mechanism.

[0014] The position adjustment mechanism includes a long rod 3, a sliding rod 4, and a connecting plate 5. The long rod 3 has arc-shaped grooves at its two opposite ends, and these grooves are slidably mounted on the annular guide strips of the first disk 1 and the second disk 2, respectively. Guided by the first disk 1 and the second disk 2, the long rod 3 can move circumferentially, thereby moving the separation mechanism to the front of the corresponding threaded hole. A hole is provided at the end of the long rod 3 away from the central column, and the sliding rod 4 is inserted into this hole. A threaded hole is provided at the end of the sidewall of the long rod 3 away from the central column, and a positioning bolt passes through this threaded hole and presses against the sidewall of the sliding rod 4. The position of the separation mechanism can be adjusted by sliding the sliding rod 4, and the position of the sliding rod 4 can be fixed by tightening the bolt. The connecting plate 5 is located on the end face of the sliding rod 4 away from the long rod 3. The length direction line of the connecting plate 5 is perpendicular to the center line of the sliding rod 4, and parallel to the axis of the central column.

[0015] The driving mechanism includes a hydraulic cylinder 6, a first sliding plate 7, a second sliding plate 8, and a pressure block 9. The connecting plate 5 has a slide rail on its end face away from the slide rod 4 along its length. Limit blocks are provided at both ends of the connecting plate 5's end face away from the slide rod 4 along its length. The function of the limit blocks is to prevent the sliding plates from sliding off the connecting plate 5. One end of both the first sliding plate 7 and the second sliding plate 8 is slidably mounted on the slide rail of the connecting plate 5. The relative sliding of the first sliding plate 7 and the second sliding plate 8 causes the screw 13 and the sleeve 14 to slide synchronously at their ends, ultimately causing the end cover and the motor housing to move relative to each other, and finally separating the end cover and the motor. The hydraulic cylinder 6 is located on the end face of the first sliding plate 7 near the second sliding plate 8, and its piston rod passes through a hole in the second sliding plate 8. A pressure block 9 is provided at the end of the piston rod of the hydraulic cylinder 6, and the second sliding plate 8 is located between the first sliding plate 7 and the pressure block 9. The movement of the piston rod driven by the hydraulic cylinder causes the first sliding plate 7 and the second sliding plate to move closer together, thereby causing the screw and the sleeve ends to move away from each other, and ultimately causing the end cover and the motor to move away from each other.

[0016] The separation mechanism includes a first ring 10, a second ring 11, a first annular plate, a second annular plate, a pull rod 12, a screw 13, and a sleeve 14. The first annular plate is disposed at the end of the first end of the pull rod 12, and the second annular plate is disposed at the end of the first end of the sleeve 14. The first ring 10 is disposed at the end of the second sliding plate 8, and the second ring 11 is disposed at the end of the first sliding plate 7. A guide groove is provided on the inner wall of both the first ring 10 and the second ring 11. The first annular plate is disposed in the guide groove on the inner wall of the first ring 10. The first annular plate can rotate within the first ring 10, and the second annular plate can rotate within the guide groove of the second ring 11, which allows the outer nut at the end of the screw and the sleeve to rotate and be threadedly connected to the corresponding threaded hole. The second annular plate is disposed in the guide groove on the inner wall of the second ring 11; the pull rod 12 passes through the center hole of the sleeve 14; the relative displacement between the two slide plates drives the relative displacement between the pull rod 12 and the sleeve 14, ultimately causing the end cover to separate from the motor housing; a screw 13 is provided at the end of the pull rod 12 away from the first annular plate, and the threaded hole of the motor housing is threadedly connected to the screw 13. That is, the screw 13 is connected only to the threaded hole on the motor housing that mates with the end cover, and the length of the screw 13 is less than the depth of the threaded hole on the motor housing, which ensures that the screw 13 is only connected to the threaded hole on the motor housing; an external thread is provided at the end of the outer wall of the sleeve 14 away from the second annular plate, and the external thread at the end of the sleeve 14 is threadedly connected to the threaded hole of the end cover.

[0017] Operating principle: Remove all bolts connecting the motor and end cover, aligning the original bolt positions with the motor threaded holes and end cover threaded holes. Then adjust the positions of each slide block so that screw 13 aligns with the original threaded holes of the removed bolts. Extend the excess slide rod 4 of the end cover removal section to its maximum length, so that it passes over the motor and is not used. Then rotate pull rod 12, causing screw 13 to rotate accordingly until it reaches the deepest point of the motor threaded hole. Once all screws 13 have reached the deepest point of their respective motor threaded holes, rotate sleeve 14. Screw the external thread of the sleeve 14 into the threaded hole of the end cap, ensuring that the external nut at the end of the sleeve 14 does not contact the threaded hole of the motor. Once the sleeve 14 is in place, there will be an external thread at the end of the screw 13 and the sleeve at the original bolt position. Then, start the hydraulic cylinder 6 to retract the piston rod, and the pressure block 9 will drive the two slide plates to move closer to each other, thereby driving the screw and sleeve to move away from each other. This force is applied to the end cap, pushing the end cap away from the motor until the end cap is removed. Then, rotate the pull rod 12 and the sleeve to unscrew them from the threaded hole of the end cap until the end cap is completely removed.
