Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing, and in particular to a multi-axis linkage machining positioning device for shell milling. Background Technology

[0002] A multi-axis linkage machining positioning device for shell milling achieves precise positioning and reliable clamping of the shell through a clamping structure and positioning design, avoiding accuracy deviations caused by vibration and displacement during machining. It effectively ensures the machining accuracy of complex curved surfaces during multi-axis linkage machining, improves the machining quality and consistency of shell parts, and shortens clamping time through efficient clamping. This adapts to the production needs of diverse and high-precision products, providing stable and reliable technical support for shell machining in aerospace, precision instruments, and other fields, and promoting the improvement of precision manufacturing efficiency and automation levels.

[0003] The multi-axis linkage machining positioning device for shell milling adopts standardized jaws and vises, which are commonly used in existing positioning devices, to clamp the shell. Its main applications are the machining of complex shells in aerospace, precision components for automotive engines, and high-precision shells for medical devices and communication equipment, meeting the manufacturing requirements of these fields for high precision and high consistency of parts.

[0004] In existing technologies, some multi-axis linkage machining positioning devices for shell milling typically use standardized jaws and vises to clamp the shell. However, these positioning devices can usually only clamp standard shells and shells within a certain size range, making it difficult to clamp shells of different sizes and shapes. This results in inaccurate positioning and unstable clamping during multi-axis linkage machining, leading to machining deviations and product failures, thereby reducing machining efficiency and causing waste. To address these issues, a multi-axis linkage machining positioning device for shell milling is proposed. Utility Model Content

Tooth clutch 258 is fixedly connected to control ring 259 and moves with control ring 259 to engage or disengage with tooth clutch 257. Reference Figure 1 , Figure 4 and Figure 5The clamping mechanism 3 includes a mounting plate 31, which is used to install on the top of the gear ring to fix the position of the clamping mechanism 3. The bottom of the mounting plate 31 is fixedly connected to the top of the gear ring 4. The mounting plate 31 and the gear ring 4 are fixedly connected to ensure that the clamping mechanism 3 rotates with the gear ring 4. A rotary motor 32 is fixedly connected to the outer wall of the mounting plate 31. The rotary motor 32 is used to drive the mounting frame 33 to rotate, thereby adjusting the clamping angle. The drive end of the rotary motor 32 is fixedly connected to the mounting frame 33. The mounting frame 33 is connected to the drive end of the rotary motor 32 and rotates with the rotary motor 32. A control motor 37 is fixedly connected to the outer wall of the mounting frame 33. The control motor 37 is used to drive the threaded rod 39 to rotate, thereby adjusting the position of the clamping plate 35. The drive end of the control motor 37 is fixedly connected to the threaded rod 39. The threaded rod 39 is connected to the drive end of the control motor 37, receives power, and rotates.

[0016] Two sliders 34 are slidably connected to the inner wall of the mounting bracket 33. The two sliders 34 can slide on the inner wall of the mounting bracket 33 to drive the clamping plate 35 to move. The outer wall of the threaded rod 39 is threadedly connected to the inner wall of the two sliders 34. The threaded rod 39 is connected to the sliders 34 through the thread, converting the rotational motion into the linear motion of the sliders 34. The top of each slider 34 is fixedly connected to the clamping plate 35. The clamping plate 35 is fixedly connected to the slider 34 and moves with the slider 34 to clamp the shell. Metal springs 36 are fixedly connected to the front and rear sides of the clamping plate 35. The metal springs 36 are fixed on the clamping plate 35 and use elastic deformation to achieve tight clamping of the shell. The inner wall of the mounting bracket 33 is provided with a sliding groove 38. The sliding groove 38 provides guidance and track for the sliding of the sliders 34. The outer walls of the two sliders 34 are slidably connected to the inner wall of the sliding groove 38. The sliders 34 slide along the inner wall of the sliding groove 38 to ensure the smoothness and accuracy of the sliding.

[0017] Working principle: When it is necessary to clamp the shell, the position of the clamping mechanism 3 needs to be adjusted first so that the clamping mechanism 3 can clamp the thin wall of the shell. The clamping mechanism 3 can be adjusted separately according to the situation. At this time, the transmission motor 261 starts and drives the bevel gear shaft 262 to rotate. The rotation of the bevel gear shaft 262 drives the control gear 263 to rotate. The rotation of the control gear 263 drives the meshing gear ring 4 to rotate, thereby realizing the position adjustment of the clamping mechanism 3 at the top of the gear ring 4. If the position adjustment of the clamping mechanism 3 at the top of the gear ring 5 is to be performed, the working principle is the same.

[0018] If it is necessary to simultaneously adjust the position of the clamping mechanism 3 at the top of the gear ring 25 and the gear ring 4, the cylinder 251 is activated. The activation of the cylinder 251 drives the connecting plate 252 to move. The movement of the connecting plate 252 drives one end of the control plate 255 to move. Due to the restriction of the control plate 255 by the rotating shaft 253, the other end of the control plate 255 will drive the control ring 259 to slide on the outer wall of the control key 254. At this time, the sliding of the control ring 259 causes the gear clutch 258 to engage with the outer wall of the gear clutch 257. At this time, the drive motor 21 is activated, driving the coupling 22 to rotate. The rotation of the coupling 22... The drive bevel gear 23 rotates, and the coupling 22 drives another coupling 22 and another drive bevel gear 23 to rotate through the engagement between the first toothed clutch 257 and the second toothed clutch 258. This causes the coupling 22 and the other coupling 22 to rotate through the gear sets 24 that mesh with them respectively. The gear sets 24 drive the two bevel gear shafts 262 to rotate, and the two bevel gear shafts 262 drive the control gear 263 to rotate. This achieves synchronous rotation between the first gear ring 4 and the second gear ring 5, and enables synchronous adjustment of the clamping mechanism 3 on the top of the first gear ring 4 and the second gear ring 5.

[0019] When it is necessary to clamp the thin-walled parts of different housings, the control motor 37 starts and drives the threaded rod 39 to rotate. The rotation of the threaded rod 39 drives the slider 34 to slide on the inner wall of the groove 38 opened in the inner wall of the mounting bracket 33, thereby realizing the opposite or opposite movement of the two metal springs 36. This makes the two clamping plates 35 and the inner side of the mounting bracket 33 form three clamping spaces, so that the clamping plates 35 drive the metal springs 36 to clamp the thin-walled parts of the housing. The three clamping spaces can be adjusted to clamp the housing as needed.
