Description

Technical Field

[0001] This utility model relates to the field of machine tool processing technology, and in particular to a rotary positioning disc for milling machine processing. Background Technology

[0002] The milling machine positioning plate is an important accessory for milling machines, used for workpiece positioning and clamping. It is disc-shaped with positioning grooves and holes on the surface. It is fixed to the milling machine worktable with bolts and can accurately determine the position of the workpiece to ensure machining accuracy. It is suitable for mass production and machining of complex parts, and can improve machining efficiency and consistency. It is a key component to ensure accurate workpiece positioning in milling.

[0003] The rotary positioning plate allows the workpiece to rotate around the axis during milling, achieving multi-angle positioning. The rotation angle is precisely controlled by the indexing mechanism, enabling multi-face machining to be completed in one clamping, reducing repeated clamping errors and time, and improving efficiency. The positioning groove and hole structure ensures the workpiece's positional accuracy, making it suitable for parts requiring multiple processes and circumferential distribution features.

[0004] During milling, insufficient rigidity of the positioning plate base leads to elastic deformation due to the cutting force and vibration of the cutting tool. This affects the machining accuracy and surface quality of the workpiece, reducing machining efficiency and product qualification rate. In existing technologies, carbon fiber plates are embedded in the positioning plate base to enhance its rigidity and stability by utilizing the high strength and high modulus of the carbon fiber plates, effectively resisting deformation caused by cutting forces. However, in actual use, there may be unsupported positions in the base, resulting in uneven stress distribution and localized stress concentration in the unsupported areas. This causes vibration of the positioning plate, which cannot effectively guarantee machining accuracy. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rotary positioning disk for milling, which aims to improve the problem in the prior art where the base is suspended, resulting in uneven force distribution, local stress concentration in the suspended part, causing vibration of the positioning disk, and failing to effectively guarantee machining accuracy.

[0014] As a further description of the above technical solution:

[0015] The locking assembly includes multiple pins, the outer sides of which are slidably connected to the inner sides of multiple fixing holes, and fasteners are fixedly connected to the bottom of each pin.

Through the support of the hydraulic rod and the slide bar, the stability of the rotary disk during rotation is enhanced, shaking is reduced, and the rotary disk can be accurately and stably rotated and positioned during milling. This avoids the base being suspended, maintains uniform force, reduces local stress concentration during processing, reduces the vibration of the rotary disk, and effectively ensures processing accuracy.

The inner sides of the two drive gears 3062 are fixedly connected with vertical motors 3063. The rotation of the vertical motors 3063 drives the drive gears 3062, thereby driving the ring tooth 3061 and the rotating disk 302 to rotate.

[0044] Specifically, oil tank 501 stores lubricating oil. The bottom of oil tank 501 is fixedly connected to the bottom right end of the inner side of workbench 1, providing storage space for lubricating oil and ensuring the fixed installation of oil tank 501.

[0045] Reference Figure 1 , Figure 2 and Figure 3 The clamping mechanism 6 includes multiple fixed seats 601, which fix the clamps 602 to the top of the rotating disk 302. The bottoms of the multiple fixed seats 601 are all fixedly connected to the top of the rotating disk 302. The clamps 602 are fixedly connected between adjacent fixed seats 601, and the clamps 602 can clamp the device between them.

[0046] Specifically, the fixing base 601 fixes the clamp 602 to the top of the rotating disk 302, so as to achieve a stable installation of the clamp 602 on the rotating disk 302.

Clamps 602 are fixedly connected between adjacent fixing bases 601. The clamps 602 can clamp the device. The stable clamping of the device is achieved through the cooperation of multiple clamps 602.

[0047] Working principle: The workpiece to be processed is fixed by the clamp 602 of the clamping mechanism 6. Multiple fixed seats 601 securely install the clamp 602 on the top of the rotating disk 302 to achieve reliable clamping of the workpiece. The liquid pump 5031 of the lubrication mechanism 5 is started. The bottom pipe passes through the oil cover 502 to draw the lubricating oil in the oil tank 501 and deliver it to the inner and outer rings of the bearing 301 through the oil injection pipe 5032 to complete the lubrication of the rotating mechanism 3 and reduce the friction during operation. The vertical motor 3063 of the drive component 306 starts to rotate, driving the drive gear 3062 to rotate and mesh with the ring gear 3061, thereby driving the rotating disk 302 to rotate. Since the vertical motors 3063 on both sides drive synchronously, the rotating disk 302 is balanced by force and rotates smoothly.

[0048] During the rotation of the rotary disk 302, the positioning spring pin 3051 of the positioning component 305 always tends to pop out downwards. When the rotary disk 302 rotates to a specific angle, the positioning spring pin 3051 pops out and gets into the hole at the top of the positioning ring 3052, making a sound and achieving precise positioning. After positioning is completed, the locking mechanism 4 is operated to pass the pin 4051 through the fixing hole 402 of the locking ring piece 401, through the top of the substrate 2 and the worktable 1, and then fix it with the fastener 4052, so that the locking ring piece 401 and the rotary disk 302 are locked to prevent displacement during processing. The scale ring 403 at the top of the locking ring piece 401 corresponds to the calibration ring 404 at the top of the substrate 2, which can achieve precise calibration of the rotation angle, realizing precise clamping, rotation positioning and reliable locking of the device.
