Description

Technical Field

[0001] This utility model relates to the field of five-axis machining technology, specifically a synchronous drive clamping device for a five-axis machining center. Background Technology

[0002] With the increasing demand for machining complex parts such as impellers, blades, and casings in fields such as aerospace and new energy vehicles, traditional shaft machining centers cannot achieve free adjustment of tool posture and need to rely on multiple clamping, resulting in accumulated errors. Five-axis machining centers can achieve multi-directional fixation of workpieces through synchronous drive clamping devices, which can reduce the number of clamping times. In practical production applications, modern five-axis machining centers are often equipped with automated loading and unloading systems. Synchronous drive clamping devices can be linked with the system to achieve automatic clamping, clamping, and machining closed loops. Without them, manual intervention is required, making it impossible to integrate into automated production lines and causing a sharp drop in batch processing efficiency. Secondly, without rotary drive, each change of machining angle requires stopping the machine, unloading the workpiece, adjusting the fixture position, and re-clamping and calibrating. Each adjustment is time-consuming, leading to a decrease in overall production efficiency. To address these issues, the inventors have proposed a synchronous drive clamping device for five-axis machining centers to solve these problems. Utility Model Content

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] like Figure 1-9 As shown, this utility model provides a synchronous drive clamping device for a five-axis machining center, including a base 1, a rotary drive device 2 inside the base 1, and a power clamping device 3 that works in conjunction with the rotary drive device 2 on the top of the base 1. The power clamping device 3 includes a column base 31, which is fixedly installed on the top of the rotary drive device 2. A disc fixing seat 32 is fixedly installed on the top of the column base 31. A servo motor 33 is fixedly installed inside the column base 31. The drive end of the servo motor 33 is connected to a threaded rod 34 through a coupling. The other end of the threaded rod 34 is connected to a stop disc seat 35 through a threaded rotation. A transmission component 36 distributed in a ring at equal intervals is fixedly installed on the top of the column base 31.

[0014] By adopting the above technical solution, the servo motor 33 drives the threaded rod 34 to move the stop disc seat 35 upward, thereby precisely controlling the clamping of the fixture 4 through the transmission component 36, avoiding workpiece deformation due to excessive clamping.

[0015] The rotary drive device 2 includes a rotating base 21 and an electric cylinder 22. The rotating base 21 is rotatably installed inside the top of the base 1. The electric cylinder 22 is fixedly installed on one side inside the base 1. A connecting rod 23 is fixedly connected to the output end of the electric cylinder 22. A connecting rod 24 is fixedly installed at the other end of the connecting rod 23. A transmission rod 25 is rotatably installed at one end of the connecting rod 24.

[0016] By adopting the above technical solution, the electric cylinder 22 drives the rotating seat 21 to rotate along the inside of the top of the base 1 through the rigid transmission of the connecting rod 23, the connecting rod 24 and the transmission rod 25, so that the rotation angle of the rotating seat 21 is accurate.

[0017] A fixing block 26 is fixedly installed at the bottom of the rotating seat 21, and the bottom end of the fixing block 26 is rotatably connected to the end of the transmission rod 25.

[0018] By adopting the above technical solution, the fixed block 26 is fixedly connected to the bottom of the rotating seat 21, so that the transmission rod 25 drives the rotating seat 21 to rotate, ensuring the consistency of the rotation action.

[0019] The transmission assembly 36 includes a support frame 361, which is fixedly installed on the top of the disc mounting base 32. A mounting bracket 363 is slidably provided on the top of the sliding cylindrical disc 37. A connecting block 362 is provided between the support frame 361 and the mounting bracket 363, and the two ends of the connecting block 362 are rotatably connected to the top of the support frame 361 and the bottom of the mounting bracket 363, respectively. The mounting bracket 363 is slidably installed on the top of the sliding cylindrical disc 35.

[0020] By adopting the above technical solution, the support frame 361 is fixedly installed on the top of the disc fixing seat 32, the linkage block 362 rotates along the outer wall of the support frame 361, driving the mounting frame 363 to slide along the top of the stop disc seat 35, driving the clamp 4 to open and close simultaneously with consistent clamping force.

[0021] The top of the column base 31 is fixedly installed with three fixed columns 38 distributed in a ring at equal intervals. The three fixed columns 38 are slidably provided with sliding columns 39 inside, and the other end of the sliding column 39 is fixedly connected to the bottom of the stop disc seat 35.

[0022] By adopting the above technical solution, the sliding column 39 slides upward along the inner wall of the fixed column 38, accurately limiting the sliding trajectory of the stop disc seat 35.

[0023] The top of the stop disc seat 35 is fixedly installed with a stop block 310, and the bottom of the mounting bracket 363 is provided with a guide groove 364 for sliding cooperation with the stop block 310. The stop block 310 slides laterally along the inner wall of the guide groove 364.

[0024] By adopting the above technical solution, the guide groove 364 and the stop block 310 slide together, which strictly constrains the movement direction of the mounting bracket 363, so that it can only slide laterally along the stop block 310, thus avoiding possible deviation of the mounting bracket 363 during movement.

[0025] The mounting bracket 363 is fixedly mounted with a clamp 4 by screws on its top.

[0026] By adopting the above technical solution and fixing it with screws, the old fixture 4 can be quickly disassembled, which greatly improves the equipment's adaptability to processing various types of workpieces.

[0027] The threaded rod 34 passes through the top of the rotating cylindrical base 31 and the interior of the disc fixing seat 32 via threads.

[0028] By adopting the above technical solution, the servo motor 33 drives the threaded rod 34 to transmit linearly to the stop disc seat 35, thereby improving the driving accuracy.

[0029] Working principle: In actual production applications, the power clamping device 3 starts working, driving the clamp 4 to stably clamp the material, while the rotary drive device 2 rotates synchronously along the inside of the top of the base 1. When it is necessary to clamp the workpiece, such as Figure 2 , Figure 3 and Figure 4 As shown, when the servo motor 33 starts working, its drive end drives the threaded rod 34 to rotate, which in turn drives the sliding column 39 to slide upward along the inner wall of the fixed column 38, thereby causing the stop disc seat 35 to slide upward in sync. At the same time, the support frame 361, which is fixedly connected to the top of the disc fixed seat 32, drives the linkage block 362 to rotate around the outer wall of the top of the support frame 361. Meanwhile, the guide groove 364 opened at the bottom of the mounting frame 363 slides along the outer wall of the stop block 310, which in turn drives the clamp 4 at the top of the mounting frame 363 to clamp the workpiece. While the material is being clamped and rotated, according to... Figure 7 , Figure 8 and Figure 9 As shown, the electric cylinder 22 precisely drives the connecting rod 23 to slide upward under the control of the CNC system. Through the linkage of the connecting rod 24 and the transmission rod 25, it drives the fixed block 26 and the rotating seat 21 to rotate circumferentially along the inside of the top of the base 1, ensuring that the fixture 4 stably clamps the workpiece while rotating circumferentially.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
