Description

Technical Field

[0001] This utility model relates to the field of milling machine device technology, specifically a milling mechanism for the end face of a universal joint of a milling machine. Background Technology

[0002] Universal joints are key components for power transmission in heavy industrial equipment such as metallurgy and chemical industries. Their quality directly affects the stable operation of the equipment, and end milling is an important step in ensuring the assembly quality and service life of universal joints.

[0003] Application number CN202420610478.5 discloses a milling mechanism for a blade surface milling device, including an X-axis moving mechanism, a Y-axis moving mechanism, a Z-axis moving mechanism, and an R-axis swinging mechanism. This invention, through laser sensor detection and adjustment of the X-axis, Y-axis, Z-axis, and R-axis swinging mechanisms, can complete grinding and milling without blind spots. Although this invention achieves blind-spot-free milling of the blade surface through multi-axis collaboration and laser sensing, certain shortcomings still exist in actual processing. Since blade milling is a high-precision metal cutting operation, the high-speed contact between the milling cutter and the blade surface generates a large amount of metal dust and debris. This flying dust not only disperses in the processing environment but may also adhere to the guide rails of the X-axis and Y-axis moving mechanisms, affecting transmission accuracy and equipment lifespan. Furthermore, the metal dust, constantly present in the air, poses a potential hazard to the respiratory system of operators. Utility Model Content

A support rod 202 is installed at the top of the electrically controlled rotating shaft 201. A limiting hinge 203 is provided at the front end of the support rod 202. The rotating bracket assembly 2 can drive the support rod 202 to rotate through the electrically controlled rotating shaft 201, thereby adjusting the horizontal position of the lifting milling assembly 3.

[0030] The lifting milling assembly 3 includes a connecting seat 301, which is limited and installed on the front outer wall of the limiting hinge 203. A lifting transmission device 302 is fixedly installed on the top of the connecting seat 301, and a lifting storage column 304 is fixedly installed at the bottom transmission end of the lifting transmission device 302. A lifting milling head 305 is limited and installed inside the lifting storage column 304.

The lifting milling assembly 3 controls the lifting and lowering of the lifting milling head 305 by means of the lifting transmission device 302 and the lifting adjustment turntable 303 to adapt to different milling depth requirements.

[0031] The mounting ring 401 is fixedly installed on one side of the outer wall of the connecting seat 301. The dustproof component 4 drives the dustproof baffle 404 to rotate through the electric control rod 402, which blocks the splashing of chips during the milling process.

[0033] This milling machine's universal joint end face milling mechanism achieves precise milling of the universal joint end face through the coordinated operation of its various components. The dust extraction bracket assembly 1 serves as the overall support foundation, providing an installation platform for other components. Its top rotating bracket assembly 2 can rotate the support rod 202 via an electrically controlled rotating shaft 201, thereby adjusting the horizontal position of the lifting milling assembly 3. The lifting milling assembly 3 uses a lifting transmission device 302 and a lifting adjustment turntable 303 to control the lifting and lowering of the milling head 305 to adapt to different milling depth requirements. The adjusting positioning plate assembly 5 can achieve translation, tilting, and lifting of the positioning support 501 through the translation adjustment handle 503, tilt adjustment handle 504, and lifting adjustment handle 505 respectively, ensuring precise positioning of the universal joint to be processed.

[0034] The dustproof component 4 drives the dustproof baffle 404 to rotate via the electric control rod 402, which blocks the splashing of chips during the milling process. At the same time, the dust suction pipe 103 can promptly suck away the dust and chips generated during processing, keeping the working environment clean.

[0035] During operation, the universal joint to be processed is placed on the positioning support 501 of the adjusting positioning plate assembly 5. By rotating the translation adjustment handle 503, the positioning support 501 is moved on the translation base 502 to adjust the horizontal position of the workpiece. By rotating the tilt adjustment handle 504, the tilt angle of the translation base 502 is adjusted to ensure that the end face of the workpiece is matched with the milling direction of the lifting milling head 305. By operating the lifting adjustment handle 505, the threaded rod 506 is rotated through the bevel gear transmission, causing the lifting worktable 104 to move up and down along the limiting slide plate on the front side of the dust collection support column 101, thereby adjusting the height of the workpiece and completing the precise positioning of the workpiece. According to the milling position requirements of the workpiece end face, the electrically controlled rotating shaft 201 of the rotating support assembly 2 is controlled to rotate, driving the support rod 202 to rotate, so that the lifting milling assembly 3 moves to a suitable horizontal position; through the lifting transmission device 302 and the lifting adjustment turntable 303, the extension length of the lifting milling head 305 in the lifting storage column 304 is adjusted to determine the milling depth, the electrically controlled rotating rod 402 of the dustproof assembly 4 is activated, driving the rotating shaft support 403 to rotate, so that the dustproof baffle 404 unfolds to a suitable position to block the debris generated during the milling process, and the lifting milling head 305 of the lifting milling assembly 3 is activated to perform milling processing on the universal joint end face. During the processing, the dust suction pipe 103 of the dust suction bracket assembly 1 works continuously to suck up the generated dust and debris. The material holding plate 102 is used to catch larger debris that may fall. After the milling work is completed, the lifting milling head 305 is turned off, the electric control rotating rod 402 is controlled to reset the dust baffle 404, and then the finished workpiece is removed by adjusting the positioning plate assembly 5.
