Description

Technical Field

[0001] This utility model relates to the field of ball screw processing technology for electric cylinders, specifically a cutting device for processing ball screws for electric cylinders. Background Technology

[0002] Electric cylinders, as devices that convert the rotary motion of an electric motor into linear motion, are widely used in industrial automation. Among them, the ball screw, as the core transmission component of the electric cylinder, possesses advantages such as high-precision positioning, high-efficiency transmission, high rigidity load-bearing capacity, and good wear resistance, making it a key factor in achieving precise linear motion control. Therefore, the machining quality and precision of the ball screw have a significant impact on the performance of the electric cylinder, and the cutting device plays a crucial role in the ball screw machining process.

[0003] According to the patent application disclosed on the Internet (authorization announcement number: CN221603349U), "This utility model provides a cutting device for ball screw processing, including a cutting machine base plate. A cutting support frame is fixedly installed on the top of the cutting machine base plate. A first clamping plate is fixedly installed on the cutting support frame. A plurality of hydraulic telescopic arms are fixedly installed on the top of the cutting support frame. A second clamping plate is movably installed on the top of the first clamping plate. A semi-cylindrical mounting groove is provided on both the first and second clamping plates. The bottom end of the second clamping plate is fixedly connected to the top of the hydraulic telescopic arm."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] This utility model, through the inclusion of a first clamping plate, a hydraulic telescopic arm, a second clamping plate, a mounting bracket, a main cutting blade, and a secondary cutting blade, effectively solves the problem that most existing metal cutting machines of this type only have one cutting module, allowing only that module to cut in a single direction. However, in actual use, this device only fixes the lead screw raw material through the first and second clamping plates on the upper and lower sides. Moreover, lead screw raw materials of different sizes have different diameters and lengths. During the processing and cutting process, the lead screw may move back and forth due to vibration or cutting force, resulting in an uneven cutting surface and affecting processing accuracy. Therefore, there is a need to improve the cutting device for processing ball screws with electric cylinders. Utility Model Content

A connecting rod 412 is rotatably connected to the right side of the slot frame 411. A connecting column 414 is fixedly connected to the end of the connecting rod 412 away from the slot frame 411. A clamping column 415 is fixedly connected to the outside of the connecting column 414.

After it is fixed, the electric push rod 51 is activated by the cutting mechanism 5, which pushes the push frame 52 to move, so that the cutting blade 54 moves downward. At the same time, the motor 53 is activated, which drives the cutting blade 54 to rotate. Simultaneously, the motor 8 set at the bottom drives the cutting blade 9 to rotate. The position is adjusted by its electric push rod 6, thereby completing the cutting work.
