Description

Technical Field

[0001] This utility model relates to the technical field of speed reducer mounting bases, specifically a harmonic speed reducer mounting base. Background Technology

[0002] Harmonic reducers, also known as harmonic gear reducers, are mainly composed of four basic components: a wave generator, flexible gears, flexible bearings, and rigid gears. Harmonic drive reducers are a type of gear transmission that uses a wave generator fitted with flexible bearings to cause the flexible gears to undergo controllable elastic deformation, which then meshes with the rigid gears to transmit motion and power. Harmonic reducers are increasingly widely used in aviation, aerospace, energy, navigation, shipbuilding, bionic machinery, common military equipment, machine tools, instruments, electronic equipment, mining and metallurgy, transportation, hoisting machinery, petrochemical machinery, textile machinery, agricultural machinery, and medical devices.

[0003] Existing harmonic reducer mounting bases mainly achieve positioning through bolt fixing and rigid clamping connection, which is relatively complex to install. Moreover, existing technologies generally rely on pre-set adapter interfaces of different specifications or the addition of adjustment shims to cope with the limited installation space. The adjustment range and flexibility are limited. When facing changing installation environments, it is necessary to frequently replace parts or re-process the mounting base, which increases costs and labor time. Utility Model Content

[0014] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] Please see the appendix Figure 1-4 This application provides the following technical solutions.

[0016] A harmonic reducer mounting base includes a fixed base 1, inside which a harmonic reducer 4 is disposed, and a fixing ring 2 is disposed on the top of the fixed base 1; the fixed base 1 includes a fixed base body 11, on which four rotating grooves 16 are opened, and clamps 3 are provided on the inner walls of the four rotating grooves 16, each clamp 3 including a rotating shaft 33, both ends of the rotating shaft 33 being fixedly connected to the rotating grooves 16, a rotating component 31 being rotatably connected to the outer wall of the rotating shaft 33, an adjusting sleeve 34 being fixedly connected to the top of the rotating component 31, an adjusting groove 35 being opened on the side wall of the adjusting sleeve 34, a fixing clamp 37 being slidably connected to the inner wall of the adjusting groove 35, a plurality of limiting holes 36 being opened on the top of the adjusting sleeve 34, the limiting holes 36 being arranged in a straight line, a receiving groove 38 being opened on the top of the fixing clamp 37, a second spring 39 being fixedly connected to the inner wall of the receiving groove 38, a limiting pin 310 being fixedly connected to the top of the second spring 39, and the limiting pin 310 being able to be inserted into the inner wall of the plurality of limiting holes 36.

[0017] It should be noted that when the fixing clips 37 wear out after prolonged use, making them unable to contact the harmonic reducer 4 and causing the harmonic reducer 4 to become unstable, the operator can press the limit pins 310 into the inner wall of the storage groove 38. The second spring 39 will generate elastic potential energy until the fixing clips 37 can slide and adjust in the inner wall of the adjustment groove 35 until all four fixing clips 37 are in contact with the harmonic reducer 4 and are firmly fixed. Then, the second spring 39 can release its elastic potential energy, pushing the limit pins 310 into the corresponding limit holes 36 for fixing. This improves the flexibility of the device. At the same time, if the fixing clips 37 are severely worn, they can be directly disassembled and replaced, avoiding the need to replace the entire device and reducing production costs.

[0018] A spring 13 is fixedly connected to the bottom of the inner wall of the fixed base body 11. A placement plate 14 is fixedly connected to the top of the spring 13. The outer wall of the placement plate 14 is slidably connected to the fixed base body 11. Four connecting pieces 17 are fixedly connected to the bottom of the placement plate 14. The outer wall of the connecting pieces 17 is rotatably connected to the rotating piece 31. Four sliding grooves 15 are opened on the top of the fixed base body 11. The fixed retaining ring 2 includes a rotating ring 21. Four anti-detachment strips 24 are fixedly connected to the bottom of the rotating ring 21. The four anti-detachment strips 24 are slidably connected to the four sliding grooves 15 respectively. Four movable grooves 22 are opened through the top of the rotating ring 21. A fixed groove 23 is opened on one side of each of the four movable grooves 22. When the clamp 3 clamps the harmonic reducer 4, the rotating ring 21 can be rotated so that the adjusting sleeve 34 fits against the inner wall of the fixed groove 23.

[0019] It should be noted that during use, the operator first places the harmonic reducer 4 on the upper end of the placement plate 14. After placement, the operator presses the placement plate 14 into the inner wall of the fixed base body 11, causing the harmonic reducer 4 to move downward. The spring 13 contracts to generate elastic potential energy, and at the same time, the connecting piece 17 drives the clamp 3 to move. The rotating piece 31 rotates around the rotating shaft 33 on the inner wall of the rotating groove 16. The operator squeezes and clamps the harmonic reducer at the upper end of the placement plate 14 by the fixed clamp 37 in the adjusting sleeve 34. At this time, the operator can slide the anti-detachment strip 24 inside the sliding groove 15 and rotate the rotating ring 21 to drive the clamp 3 to detach from the movable groove 22 and enter the inner wall of the fixed groove 23. At this time, the operator stops squeezing the harmonic reducer 4, causing the spring 13 to release its elastic potential energy and push the harmonic reducer 4 upward to squeeze the fixed clamp 37. The fixed clamp 37 is restricted by the fixed retaining ring 2 to firmly fix the harmonic reducer 4, making the installation relatively quick.

[0020] In use, the operator first places the harmonic reducer 4 on the upper end of the placement plate 14. After placement, pressing the placement plate 14 causes it to retract into the inner wall of the fixed base body 11, causing the harmonic reducer 4 to move downwards. The spring 13 contracts, generating elastic potential energy. Simultaneously, the connecting piece 17 drives the clamp 3 to move, and the rotating piece 31 rotates around the rotating shaft 33 on the inner wall of the rotating groove 16. The operator then clamps the harmonic reducer at the upper end of the placement plate 14 by pressing the fixed clamp 37 in the adjusting sleeve 34. At this time, the operator can slide the anti-detachment strip 24 inside the sliding groove 15 and rotate the rotating ring 21 to drive the clamp 3 to detach from the movable groove 22 and enter the inner wall of the fixed groove 23. At this point, the operator stops pressing the harmonic reducer 4, causing the spring 13 to release its elastic potential energy and push the harmonic reducer 4 upwards. The clamping clip 37 is pressed, and the clamping clip 37 is restricted by the retaining ring 2 to firmly fix the harmonic reducer 4, making the installation relatively quick. When the clamping clip 37 wears down after long-term use and can no longer contact the harmonic reducer 4, making the harmonic reducer 4 unstable, the operator can press the limit pin 310 into the inner wall of the storage groove 38. The second spring 39 generates elastic potential energy until the clamping clip 37 can slide and adjust in the inner wall of the adjustment groove 35 until all four clamping clips 37 are in contact with the harmonic reducer 4 and are firmly fixed. Then the second spring 39 can release elastic potential energy and push the limit pin 310 into the corresponding limit hole 36 for fixing, improving the flexibility of the device. At the same time, the clamping clip 37 can be directly disassembled and replaced if it is severely worn, avoiding the need to replace the entire device and reducing production costs.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
