A harmonic drive reducer is a gear transmission system where a harmonic generator is fitted with a flexible bearing, causing the flexible gear to undergo controllable elastic deformation and mesh with the rigid gear to transmit motion and power.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings.

[0036] like Figure 1 As shown below, the structure and function of a harmonic reducer housing processing device will be described in detail.

[0037] A harmonic reducer housing processing device includes a processing bracket, the processing bracket includes two supporting side plates 11, a connecting bracket 12 is fixedly connected between the two supporting side plates 11, a lead screw I 13 is rotatably connected to the connecting bracket 12, and a power mechanism I that drives the lead screw I 13 to rotate is fixedly connected to the connecting bracket 12, preferably a servo motor.

[0038] The processing support is equipped with an extrusion mechanism 40, which includes a sliding seat 41, a telescopic mechanism II 42, a lifting support 43, a rotating ring 44, extrusion rods 45 and extrusion balls 46. The sliding seat 41 is slidably connected to the connecting support 12. The telescopic mechanism II 42 is fixedly connected to the sliding seat 41. The lifting support 43 is fixedly connected to the telescopic end of the telescopic mechanism II 42. The rotating ring 44 is rotatably connected to the lifting support 43. Multiple extrusion rods 45 are fixedly connected to the rotating ring 44. Each extrusion rod 45 is fitted with an extrusion ball 46 with clearance.

[0039] A power mechanism V for driving the rotating ring 44 to rotate is fixedly connected to the lifting bracket 43. The power mechanism V is preferably a servo motor.

[0040] When using, such as Figure 1 As shown, the circular plate 60 to be processed is placed between multiple support mechanisms 30 on both sides. The power mechanism I is started, and the output shaft of the power mechanism I starts to rotate. The output shaft of the power mechanism I drives the lead screw I 13 to rotate. When the lead screw I 13 rotates, it drives the sliding seat 41 to move through the thread. The sliding seat 41 drives the telescopic mechanism II 42 to move. The telescopic mechanism II 42 drives the lifting bracket 43 to move. The lifting bracket 43 drives the rotating ring 44 to move. The rotating ring 44 drives the extrusion rod 45 to move. The extrusion rod 45 drives the extrusion ball 46 to move, so that the extrusion ball 46 moves laterally to different positions.

[0041] Start the telescopic mechanism II 42. The telescopic mechanism II 42 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism II 42 drives the lifting bracket 43 to move. The lifting bracket 43 drives the rotating ring 44 to move. The rotating ring 44 drives the extrusion rod 45 to move. The extrusion rod 45 drives the extrusion ball 46 to move, thereby adjusting the height of the extrusion ball 46.

[0042] Multiple extrusion balls 46 can be configured with different sizes to meet different usage requirements. When it is necessary to adjust the contact size between the extrusion balls 46 and the circular plate 60 to be processed according to different usage requirements, the power mechanism V is activated. The output shaft of the power mechanism V starts to rotate, which drives the rotating ring 44 to rotate. The rotating ring 44 drives multiple extrusion rods 45 to rotate, which in turn drives multiple extrusion balls 46 to move, changing the position of the extrusion balls 46 and adjusting the contact size between the extrusion balls 46 and the circular plate 60 to be processed, thereby meeting different usage requirements.

[0043] Telescopic mechanism I21 is fixedly connected to both support side plates 11. A transverse support 22 is fixedly connected to the telescopic end of both telescopic mechanism I21. A rotating support 23 is rotatably connected to both transverse support 22. A lead screw II24 is fixedly connected to both rotating support 23.

[0044] A power mechanism II for driving the rotating bracket 23 to rotate is fixedly connected to the transverse support 22. The power mechanism II is preferably a servo motor.

[0045] Multiple support mechanisms 30 are slidably connected to the rotating bracket 23, and all the support mechanisms 30 are threadedly connected to the lead screw II 24.

[0046] The support mechanism 30 includes a sliding block 31, a threaded sleeve 32 rotatably connected to the sliding block 31, an annular cavity 33 fixedly connected to the sliding block 31, a plurality of threaded blocks 34 slidably connected inside the annular cavity 33, a support arc plate 35 fixedly connected to each threaded block 34, a support top plate 36 fixedly connected to each support arc plate 35, a threaded disc 37 rotatably connected to the annular cavity 33, and the plurality of threaded blocks 34 are all threadedly connected to the threaded disc 37.

[0047] A power mechanism Ⅲ for driving the threaded sleeve 32 to rotate is fixedly connected to the sliding block 31. The power mechanism Ⅲ is preferably a servo motor.

[0048] A power mechanism IV for driving the threaded disk 37 to rotate is fixedly connected to the annular cavity 33. The power mechanism IV is preferably a servo motor.

[0049] Multiple supporting arc plates 35 on two adjacent supporting mechanisms 30 are staggered and interwoven with each other;

[0050] In use, the circular plate 60 to be processed is placed between multiple support mechanisms 30 on both sides. The circular plate 60 is preferably the raw material for processing the housing of a harmonic reducer. The telescopic mechanism I 21 is activated. The telescopic mechanism I 21 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I 21 drives the transverse support 22 to move, the transverse support 22 drives the rotating support 23 to move, and the rotating support 23 drives the multiple support mechanisms 30 on it to move. Figure 1 As shown, multiple support mechanisms 30 on both sides approach each other, and both support mechanisms 30 on both sides are in contact with the circular plate 60 to be processed, thereby completing the fixed clamping of the circular plate 60 to be processed.

[0051] Upon startup, the power mechanism I and the telescopic mechanism II 42 drive the extrusion ball 46 to move, adjusting the position of the extrusion ball 46 so that it contacts the circular plate 60 to be processed;

[0052] When the power mechanism II is started, the output shaft of the power mechanism II begins to rotate. The output shaft of the power mechanism II drives the rotating bracket 23 to rotate, and the rotating bracket 23 drives multiple support mechanisms 30 to rotate. The support mechanisms 30 contact the circular plate 60 to be processed, and drive the circular plate 60 to be processed to rotate.

[0053] like Figure 3 As shown, in order to facilitate the explanation of the working state of the multiple support mechanisms 30 on the rotating bracket 23 on one side, the first support mechanism 30 that contacts the circular plate 60 to be processed is defined as the first support mechanism 30, and the support mechanisms 30 that are away from the circular plate 60 to be processed are defined as the second support mechanism 30 and the third support mechanism 30, and so on.

[0054] Furthermore, such as Figure 3 As shown, multiple support plates 36 on the first support mechanism 30 on both sides contact the circular plate 60 to be processed. The telescopic mechanism II 42 is activated, adjusting the extrusion ball 46 to move to the outside of the multiple support arc plates 35 surrounding the first support mechanism 30. The gap between the extrusion ball 46 and the support arc plates 35 is one circular plate 60 to be processed. The power mechanism I is activated, and the output shaft of the power mechanism I drives the lead screw I 13 to rotate, causing the extrusion ball 46 to move laterally. The extrusion ball 46 then extrudes the circular plate 60 to be processed, causing it to adhere to the multiple support arc plates 35, thus forming a shell 62. At this time, the power mechanism IV on the second support mechanism 30 is activated. The output shaft of mechanism IV starts to rotate, and the output shaft of power mechanism IV drives the threaded disc 37 to rotate. When the threaded disc 37 rotates, it drives multiple threaded blocks 34 to move through the threads. The threaded blocks 34 drive the support arc plate 35 to move. The support arc plate 35 drives the support top plate 36 to move, thereby adjusting the outer diameter formed by multiple support arc plates 35 on the second support mechanism 30. The multiple support top plates 36 provide internal support for the circular plate 60 to be processed. The extrusion ball 46 extrudes the outer side of the circular plate 60 to be processed. The circular plate 60 to be processed rotates, and the extrusion ball 46 moves upward. The extrusion ball 46 and the multiple support top plates 36 cooperate with each other to extrude and process the circular plate 60 to be processed to form a shell ring 61.

[0055] Then, when the extrusion ball 46 moves to the outer diameter of the multiple support arc plates 35 outside the second support mechanism 30, the distance between the extrusion ball 46 and the support arc plate 35 is the distance of a circular plate 60 to be processed. The extrusion ball 46 moves laterally and extrudes the circular plate 60 to be processed to form a second shell 62. This process is repeated to form the harmonic reducer shell.

[0056] The circular plate 60 to be processed is clamped between the support mechanisms 30 on both sides. The extruded ball 46 can contact the circular plate 60 to be processed and cooperate with the multiple support mechanisms 30 on one side to form a shell ring 61 or a shell sleeve 62.

[0057] Furthermore, the power mechanism III is started, and the output shaft of the power mechanism III begins to rotate. The output shaft of the power mechanism III drives the threaded sleeve 32 to rotate. When the threaded sleeve 32 rotates, it drives the sliding block 31 to move laterally through the thread, thereby adjusting the lateral position of multiple support arc plates 35, and thus adjusting the length of the processing shell 62 to meet the requirements of different models.

[0058] Furthermore, the power mechanism IV is activated, and the output shaft of the power mechanism IV drives the threaded disc 37 to rotate, thereby adjusting the diameter of the expansion of multiple support arc plates 35, and thus adjusting the outer diameter of the shell ring 61 to meet the requirements of different models.

[0059] Furthermore, in order to control the processing temperature, two temperature control chambers 51 are fixedly connected to the connecting bracket 12, and two connecting pipes 52 are fixedly connected to the temperature control chambers 51; one connecting pipe 52 is connected to high-temperature gas, and the other connecting pipe 52 is connected to cooling gas. Through the two connecting pipes 52, high-temperature gas or cooling gas can be introduced into the temperature control chambers 51 according to different usage requirements, and then sprayed onto the circular plate 60 to be processed, thereby heating or cooling the circular plate 60 to be processed.

[0060] The round plate to be processed is easy to process when heated to 60°C, and easy to shape when cooled to 60°C.
