Description

Technical Field

[0001] This utility model relates to the field of electric speed reducer repair technology, and in particular to an electric speed reducer repair operation device. Background Technology

[0002] Chinese patent application CN202322915213.4 discloses an electric speed reducer maintenance device, comprising: a main body with a worktable at its top; and a pushing mechanism located inside the main body, the pushing mechanism including a motor, the output end of which is fixedly mounted with a bidirectional lead screw. This invention, by rotating the first and second pushing rods, causes a square block and the worktable to rise, which in turn causes the speed reducer to rise. During the rise of the worktable, a limiting rod moves within a moving groove, thus limiting the worktable's position. This allows the worktable to be moved to a position suitable for the operator's height, enabling the operator to repair the speed reducer without squatting or bending over, avoiding leg and back pain, thereby improving the device's practicality and maintenance efficiency.

[0003] The main body is higher than the workbench, which makes the working space for personnel on both sides of the device small. Furthermore, after the electric reducer is fixed on the workbench, it cannot rotate, making it impossible for operators to adjust the angle of the electric reducer according to its maintenance position.

The top of the top seat is rotatably connected to a support platform via a slewing bearing. A worktable is fixedly installed on the top of the support platform, and a fixing plate I and a fixing plate II are fixedly installed on both sides of the support platform, respectively. A lead screw II located inside the support platform is rotatably connected between the fixing plate I and the fixing plate II. Clamping plates that are locked inside the support platform are threaded onto the outer ends of both ends of the lead screw II. A motor II that is fixedly connected to the lead screw II is fixedly installed on the outer side of the fixing plate II. The bottom of the support platform is provided with an annular boss and a conductive mechanism is fixedly installed. A locking mechanism is fixedly installed at the bottom of the top seat.

[0011] This utility model has the following advantages:

[0012] 1. Driven by the first motor, the top seat can be raised and lowered along the axis of the telescopic rod. During this process, the top seat is lower than the surface of the worktable, which will not obstruct personnel from inspecting the electric reducer on both sides, thereby increasing the working space for personnel on both sides of the device.

[0013] 2. By loosening the lead screw, the rack can be moved along the axial direction of the lead screw. Then, through the meshing transmission of the rack and gear, the rotating shaft can be rotated.

[0022] Please see Figures 1 to 6 An electric reducer maintenance device includes a base 1, a telescopic rod 2 fixedly mounted on the top of the base 1, a top seat 3 fixedly mounted on the top of the telescopic rod 2, a bracket I4 fixedly mounted in the middle of the top of the base 1, a lead screw I5 rotatably connected inside the bracket I4, movable blocks 6 slidably connected to the top of the base 1 are threaded onto the outer sides of both ends of the lead screw I5, and brackets II7 fixedly mounted on the base 1 are rotatably connected to the outer sides of both ends of the lead screw I5 extending outside the bracket II7, and a push rod 8 is fitted between the top seat 3 and the movable blocks 6. A drive mechanism 9 is fixedly mounted on the bottom of the base 1, and the top of the top seat 3 is rotatably connected via a rotary bearing 10. A support platform 11 is provided, and a workbench 12 is fixedly installed on the top of the support platform 11. Fixing plates I13 and II14 are fixedly installed on both sides of the support platform 11, respectively. A lead screw II15 located inside the support platform 11 is rotatably connected between the fixing plates I13 and II14. Clamping plates 16 that are locked inside the support platform 11 are threaded onto the outer ends of both ends of the lead screw II15. A motor II17 that is fixedly connected to the lead screw II15 is fixedly installed on the outer side of the fixing plate II14. An annular boss 18 is provided at the bottom of the support platform 11 and a conductive mechanism 19 is fixedly installed. A locking mechanism 20 is fixedly installed at the bottom of the top seat 3.

[0023] The telescopic rod 2 is provided with a connecting plate 21 on its outer side. The connecting plate 21 can limit and support the telescopic rod 2, making it less likely to bend when subjected to external forces.

[0024] The drive mechanism 9 includes a first sprocket 91 fixedly mounted on the outside of the lead screw I5 and a first motor 92 fixedly mounted on the bottom of the base 1. A second sprocket 93 is fixedly mounted on the outside of the output shaft of the first motor 92. The first motor 92 is connected to the first motor 92 through a chain 94 mounted on the outside of the second sprocket 93. By fixing the first motor 92 to the bottom of the base 1, the legs of the personnel will not collide with the first motor 92 when the personnel walk around the device.

[0025] The conductive mechanism 19 includes a first insulating block 191 fixedly installed at the bottom of the support platform 11 and a second insulating block 192 fixedly installed inside the top seat 3. A first electrode 193 and a second electrode 194, which are electrically connected to the motor II 17, are fixedly fitted inside the first insulating block 191. A first conductive post 195 and a second conductive post 196, respectively located below the first electrode 193 and the second electrode 194, are movably fitted inside the second insulating block 192. The outer sides of the bottom ends of the first conductive post 195 and the second conductive post 196 are each provided with a locking mechanism that engages with the second insulating block. The third conductive post 197 inside the second insulating block 192 can limit the first conductive post 195 and the second conductive post 196 to prevent them from rotating. The second insulating block 192 has a spring 198 installed inside, located below the first conductive post 195 and the second conductive post 196. The elastic force of the spring 198 ensures that the first conductive post 195 and the second conductive post 196 are always in contact with the first electrode 193 and the second electrode 194 during the rotation of the support platform 11, thereby facilitating the control of the drive of the motor II17 through this circuit.

[0026] The support platform 11 has a second guide groove 22 that matches the clamping plate 16. The clamping plate 16 can move stably along the inner side of the second guide groove 22 when the lead screw II 15 rotates, so as to clamp and fix the electric reducer placed on the worktable 12 through the clamping plate 16.

[0027] The locking mechanism 20 includes a fixed frame 201 fixedly installed at the bottom of the top seat 3 and a rotating shaft 202 rotatably connected to the inside of the top seat 3 and engaged with the outside of the annular boss 18. A lead screw 203 is rotatably connected inside the fixed frame 201. A rack 204, engaged with the inside of the fixed frame 201, is threaded onto the outside of the lead screw 203. A turntable 205 is fixedly fitted onto the outer side of one end of the lead screw 203 extending outside the fixed frame 201. A first part adapted to the rack 204 is opened inside the fixed frame 201. The guide groove 206 and the outer side of the bottom end of the rotating shaft 202 are fixedly fitted with a gear 207 that meshes with the rack 204. The turntable 205 can rotate the lead screw 203 and drive the rack 204 to move along the axial direction of the lead screw 203. Then, the meshing transmission between the rack 204 and the gear 207 drives the rotating shaft 202 to rotate. At this time, the cooperation between the rotating shaft 202 and the annular boss 18 can limit and fix the support platform 11 to prevent the support platform 11 from rotating on its own.

[0028] Working principle: Driven by the first motor 92, the lead screw I5 rotates, simultaneously moving the moving block 6 along the axial direction of the lead screw I5. As the moving block 6 moves, the push rod 8 pushes the top seat 3 upwards along the axial direction of the telescopic rod 2. When the worktable 12 rises to a suitable height, the first motor 92 is turned off, and motor II17 is started. Driven by motor II17, the lead screw II15 rotates, simultaneously moving the clamping plate 16 around the axial direction of the lead screw II15. At this time, the clamping plate 16 clamps and fixes the electric reducer placed above the worktable 12. After the electric reducer is fixed, motor II17 is turned off. The turntable 205 can loosen the lead screw 203 by rotating it. The rotation of the lead screw 203 drives the rack 204 to move along the axis of the lead screw 203. The meshing transmission of the rack 204 and the gear 207 drives the rotating shaft 202 to rotate around its own axis. At this time, the limiting position of the rotating shaft 202 on the annular boss 18 can be released. The worktable 12 can be manually rotated to change the angle of the electric reducer. After the maintenance angle of the electric reducer is adjusted, the lead screw 203 can be tightened and fixed through the turntable 205. At this time, the cooperation of the rotating shaft 202 and the annular boss 18 can limit and fix the support platform 11, preventing the worktable 12 from rotating on its own.
