Description
Technical Field
[0001] This invention relates to the field of flywheel machining clamping device technology, specifically to a flexible flywheel flexible disc machining equipment. Background Technology
[0002] Flexible flywheels are important power transmission components in engines. The precision of their manufacturing and processing will affect the machine's performance and lifespan. During the processing of the flywheel disc, there are high requirements for the machining of its inner hole.
[0003] For thin-walled annular flywheel discs, the inner bore is typically machined using a lathe with fan-shaped chucks to clamp the outer diameter. However, due to the easily deformable nature of thin-walled parts, this clamping method can cause issues such as... Figure 1 The flange 20 and wheel surface of the flywheel 10 shown are radially deformed, making it difficult to guarantee the machining accuracy of the center wheel hole 30, which affects the accuracy and efficiency of subsequent machining. Summary of the Invention
[0004] Therefore, the present invention provides a flexible flywheel and flexible disk processing equipment to solve the above-mentioned defects in the prior art.

[0007] The centering positioning component includes a support plate disposed on the outside of the support platform and a side pressure rod arranged in a ring array on the outside of the support platform. The side pressure rod is slidably disposed on the support plate through a guide hole, and a pressure block is provided at the inner end of the side pressure rod.
[0008] The side support assembly includes an air cylinder disposed below the outer end of the side pressure rod. Inside the air cylinder, an air plug that can slide along the air cylinder is provided by a third spring. The air cylinder is connected to an inflatable bladder disposed on the outer wall of the support platform via an air pipe.
[0009] The pressure roller assembly includes an upper pressure ring that is raised and lowered, and a lower pressure ring that is mounted below the upper pressure ring by a second spring. The lower pressure ring is provided below the upper pressure ring, which can act on the outer end of the side pressure rod to cause the side pressure rod to move inward, and the lower pressure rod can also act on the top of the air plug.
[0010] Preferably, the diameter of the support platform is smaller than the diameter of the flywheel to be processed.
[0011] Preferably, the side pressure rod is slidably mounted on the support plate by a return spring, the inner end of the pressure block is slidably mounted with an arc-shaped pressure plate by a first spring, the outer end of the side pressure rod is constructed as a first wedge-shaped surface, and the lower end of the lower pressure rod is constructed as a second wedge-shaped surface that can cooperate with the first wedge-shaped surface. When the second wedge-shaped surface below the lower pressure rod presses against the first wedge-shaped surface, it will cause the side pressure rod where the first wedge-shaped surface is located to displace inward.
[0012] Preferably, the side support assembly further includes a U-shaped slider slidably disposed on the support platform via a fourth spring annular array. The U-shaped slider includes guide rods slidably disposed on the side wall of the support platform and an arc-shaped rubber plate connected between the outer ends of the two guide rods. A base plate is disposed below the U-shaped slider, and an airbag is disposed on the base plate inside the U-shaped slider.

[0015] The present invention has the following advantages:
[0016] This invention achieves automated, integrated operation of the clamping process for thin-walled flywheel parts through the cooperation of the support stage, centering positioning component, side support component, and pressure roller component. On the one hand, it improves clamping efficiency; on the other hand, it achieves pre-positioning of the flywheel in both horizontal and vertical directions without only tightly pressing the flywheel. Then, the flywheel is positioned from the inside by an airbag, preventing the flywheel surface and flange from being rigidly squeezed and deformed. The upper pressure ring presses against the lower pressure ring to compress the upper plate surface of the flywheel, and the inflated airbag also supports the bottom surface of the outer ring of the flywheel. This invention is not only suitable for clamping and positioning flywheels of various specifications, but also increases the support area on the flywheel surface, reduces the deformation of the flywheel during the center hole forming process, and improves the overall clamping and processing efficiency of thin-walled flywheel parts.

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0030] like Figures 1 to 6 As shown, the present invention provides a flexible flywheel and flexible disk processing equipment, including a support platform 1, a centering positioning component 2, a side support component 3, and a pressure roller component 4.
[0031] The support platform 1 includes a rotatable base 101 and a support platform 102 mounted on the base 101. The diameter of the support platform 102 is smaller than the diameter of the flywheel 10 to be processed.
[0032] The centering positioning component 2 includes a support plate 208 disposed on the outside of the support platform 102 and side pressure rods 202 arranged in a ring array on the outside of the support platform 102. The side pressure rods 202 are slidably disposed on the support plate 208 through guide holes 207, and a pressure block 201 is provided at the inner end of the side pressure rods 202.
[0033] The side pressure rod 202 is slidably mounted on the support plate 208 via a reset spring 203, and the inner end of the pressure block 201 is slidably mounted with an arc-shaped pressure plate 206 via a first spring 204.
[0034] The side support assembly 3 includes an air cylinder 301 located below the outer end of the side pressure rod 202. Inside the air cylinder 301, a third spring (not shown) provides an air plug 303 that can slide along the air cylinder 301. The air cylinder 301 is connected to an inflatable bladder 305 located on the outer wall of the support platform 102 via an air pipe 304. Specifically:
[0035] The side support assembly 3 further includes a U-shaped slider 307 slidably disposed on the support platform 102 via a fourth spring 302 in a circular array. The U-shaped slider 307 includes a guide rod 311 slidably disposed on the side wall of the support platform 102 and an arc-shaped rubber plate 310 connected between the outer ends of the two guide rods 311. A base plate 308 is disposed below the U-shaped slider 307. An airbag 305 is disposed inside the U-shaped slider 307 on the base plate 308, and the airbag 305 is connected between the outer wall of the support platform 102 and the inner wall of the arc-shaped rubber plate 310.
[0036] The pressure roller assembly 4 includes an upper pressure ring 402 that is raised and lowered, and a lower pressure ring 403 that is mounted below the upper pressure ring 402 via a second spring 404. The pressure roller assembly 4 also includes a support frame 401 mounted on the chassis 101. The upper pressure ring 402 is mounted on the support frame 401 via a lifting cylinder 408. A guide rod 405 is vertically mounted on the lower pressure ring 403. The upper pressure ring 402 is vertically slidably mounted on the guide rod 405. The second spring 404 is fitted onto the guide rod 405 between the upper pressure ring 402 and the lower pressure ring 403.
[0037] The central protrusion on the bottom surface of the upper pressure ring 402 can extend to the central hole of the lower pressure ring 403.
[0038] Below the upper pressure ring 402, there is a lower pressure rod 406 that can act on the outer end of the side pressure rod 202 to cause the side pressure rod 202 to move inward.
[0039] The outer end of the side pressure rod 202 is configured as a first wedge surface 205, and the lower end of the lower pressure rod 406 is configured as a second wedge surface 407 that can cooperate with the first wedge surface 205. When the second wedge surface 407 below the lower pressure rod 406 presses the first wedge surface 205, it will cause the side pressure rod 202 where the first wedge surface 205 is located to shift inward.
[0040] Furthermore, the downward pressure rod 406 can also act on the top of the air plug 303.
[0041] The working principle of the device of this invention is as follows:
[0042] I. Reservation:
[0043] The flywheel 10 to be processed is placed on the support platform 102 with the flange 20 side facing down, and the upper pressure ring 402 is driven to descend by the lifting cylinder 408 on the support frame 401.
[0044] On one hand, the lower pressure ring 403, installed below the upper pressure ring 402, lightly presses against the surface of the outer ring of the flywheel 10; on the other hand, as the lower pressure rod 406, installed below the upper pressure ring 402, moves downward, its lower second wedge-shaped surface 407 presses against the first wedge-shaped surface 205 at the outer end of the side pressure rod 202, causing several side pressure rods 202 to converge towards the center simultaneously. This achieves the centered positioning of the flywheel 10 placed on the support platform 102. Furthermore, due to the elastic connection between the arc-shaped pressure plate 206 and the first spring 204, the arc-shaped pressure plate 206 elastically presses against the outer wall of the flange 20 of the flywheel 10 without causing deformation of the flange 20; thus achieving the initial centered positioning of the flywheel 10.
[0045] II. Clamping and Positioning:
[0046] As the lower pressure rod 406 connected to the upper pressure ring 402 descends further, the lower end of the lower pressure rod 406 squeezes the air plug 303, and the air plug 303 squeezes the gas inside the air cylinder 301. The gas inside the air cylinder 301 enters the inflation bladder 305 through the air pipe 304. The inflation bladder 305 drives the U-shaped slider 307 to move outward along the guide groove 309. The arc-shaped rubber plate 310 on the outside of the guide groove 309 gradually presses against the inner side wall of the flange 20 of the flywheel 10, so as to prevent the rotating flywheel 10 from being displaced by the elastic side pressure of the arc-shaped pressure plate 206 during the machining of the center hole, thereby achieving the clamping and positioning of the flywheel 10 in the horizontal direction.
[0047] Furthermore, the upper surface of the airbag 305 gradually supports the bottom surface of the outer ring of the flywheel 10. Due to the pre-pressure of the upper pressure ring 403 on the surface of the flywheel 10, the flywheel 10 will not move upward due to the inflation of the airbag 305, thus avoiding scratching between the outer flange 20 of the flywheel 10 and the arc-shaped pressure plate 206.
[0048] Furthermore, the upper pressure ring 402 will gradually press down and squeeze the surface of the lower pressure ring 403, so that the lower pressure ring 403 is squeezed on the outer ring surface of the flywheel 10, while the upper pressure ring 402 will also squeeze on the inner ring surface of the flywheel 10, thus realizing the vertical upward clamping and positioning of the flywheel 10.
[0049] This invention achieves automated, integrated operation of the clamping process for thin-walled flywheel parts through the cooperation of the support platform 1, the centering positioning component 2, the side support component 3, and the pressure roller component 4. On the one hand, it improves clamping efficiency; on the other hand, it achieves pre-positioning of the flywheel in the horizontal and vertical directions without only tightly pressing the flywheel. Then, the flywheel is positioned from the inside by an airbag, avoiding hard compression deformation of the flywheel 10 surface and the flange 20. The upper pressure ring 402 presses the lower pressure ring 403 to tighten the upper plate surface of the flywheel 10, and the expanded airbag can also support the bottom surface of the outer ring of the flywheel. This invention is not only suitable for clamping and positioning flywheels of various specifications, but also increases the support area of the flywheel surface, reduces the deformation of the flywheel during the center hole forming process, and improves the overall clamping and processing efficiency of thin-walled flywheel parts.
[0050] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
