Description

Technical Field

[0001] This utility model relates to the field of machining, and in particular to a milling gear assembly for workpiece machining. Background Technology

[0002] In machining, it is necessary to mill teeth on the outer periphery of shafts or cylindrical workpieces. The teeth and the gear housing are integrated and are formed by milling a gear blank. To improve the wear resistance of the teeth, hard alloy powder is welded onto the tooth surface. Milled teeth are mainly wedge-shaped teeth, and their main parameters are tooth height and tooth tip angle. A gear milling machine is a machine tool for machining teeth. CNC gear milling machines can be controlled by CNC programming to perform tooth machining, making operation more convenient and work efficiency higher.

[0003] A search of Chinese patent publication number CN212823163U reveals a bevel gear milling fixture. This patent includes a fixture body, an elastic chuck installed within the fixture body, a front cover installed at the front end of the fixture body, and a tail pull rod installed at the rear end of the elastic chuck. The front cover has a calibration structure for calibrating the center line of the keyway on the workpiece and the center line of the first tooth groove to be machined. The calibration structure includes a calibration limiting rod and a calibration support. The calibration limiting rod is connected to the calibration support via a connecting rod, one end of which is hinged to the calibration support. The calibration limiting rod is perpendicularly connected to the connecting rod. This device employs... The calibration structure calibrates the center line of the keyway on the workpiece and the center line of the first tooth groove to be machined, ensuring that the two center lines coincide and meet the workpiece machining requirements. At the same time, the connecting rod and the calibration support are connected by a hinge, which facilitates calibration. However, in the existing gear milling assembly, it is difficult to disassemble the workpiece during batch gear milling operations. Tools are often required for disassembly and assembly, which affects the gear milling efficiency. Furthermore, for gear milling operations on cylindrical workpieces, which require annular gear milling, high centering accuracy and high installation precision are required. The existing gear milling assembly is inconvenient to use and install, and its applicability needs to be improved. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figure 1 — Figure 9 As shown, a milling gear assembly for workpiece machining includes a frame 101. The frame 101 contains a cavity (for illustrative purposes only) and a machining control assembly (not shown). A collection tank 102 is fixedly mounted on one side of the frame 101. A water spray assembly 103 and a milling cutter assembly 104 are mounted on the frame 101. The milling cutter on the milling cutter assembly 104 can be replaced according to the specific requirements of the milled gear. A docking mechanism is provided on the frame 101, including a docking seat 201 rotatably connected to the frame 101. An insertion interface 202 is provided inside the docking seat 201. A first conical surface 203 is provided on the inner wall of one end of the docking seat 201. The device is detachably equipped with a fixing mechanism, which includes an installation cylinder 301. A clamping cylinder 302 is welded to one end of the installation cylinder 301. In actual production, the clamping cylinder 301 and the clamping cylinder 302 form various types of clamps, which are produced and matched according to different workpieces. The clamping cylinder 302 has several annularly arranged receiving grooves 303. The outer circumferential surface of the clamping cylinder 302 is provided with a second conical surface 304 that mates with the first conical surface 203. A driving mechanism is provided inside the frame 101. The driving mechanism is used to facilitate the installation of the installation cylinder 301 and the workpiece by the operator. A limiting mechanism is installed inside the frame 101. The limiting mechanism is used to position the installation of the installation cylinder 301.

[0029] In this embodiment, the limiting mechanism includes a movable ring 501, which is movably disposed within the frame 101. The frame 101 has an annular groove 105. The movable ring 501 and the frame 101 can move relative to each other, and the movable ring 501 can rotate within the annular groove 105. The movable ring 501 has a plurality of annularly distributed elastic components, including springs 502. The springs 502 are installed within the movable ring 501, and limiting blocks 503 are installed on the springs 502. During the process of installing the mounting cylinder 301 onto the mounting block 405, the limiting blocks 503 abut against the outer periphery of the mounting cylinder 301 to prevent the mounting cylinder 301 from rotating and affecting the installation action. The limiting blocks 503 are slidably connected within the movable ring 501.

[0030] In this embodiment, the mounting cylinder 301 has several annular straight grooves 305 on its side, and the limiting block 503 has an inclined surface 504 on its opposite side. The inclined surface 504 facilitates the entry of the limiting block 503 into the straight grooves 305 on the mounting cylinder 301 during the installation process. The straight grooves 305 cooperate with the limiting block 503. The straight grooves 305 further limit the installation angle and position of the mounting cylinder 301 during installation, thereby improving the installation accuracy of the mounting cylinder 301 and improving the subsequent milling accuracy.

[0031] In this embodiment, a locking block 505 is bolted to the side of the moving ring 501, and several ring-shaped locking shafts 506 are bolted inside the frame 101. The locking shafts 506 are used to lock the locking block 505 to restrict the rotation of the moving ring 501. The arrangement of the locking shafts 506 and the locking block 505 restricts the rotation of the moving ring 501 during installation by the mounting cylinder 301 and the clamping cylinder 302. During milling, the locking shafts 506 and the locking block 505 are staggered, and the moving ring 501 can drive the mounting cylinder 301 to rotate, so that the milling cutter assembly 104 can perform ring milling on the circumferential surface of the workpiece.

[0032] In this embodiment, the driving mechanism includes a movable base 401, which is slidably connected to the frame 101. A cylinder 402 is bolted to the frame 101, and the output end of the cylinder 402 is bolted to the movable base 401. A connecting rod 403 is bolted to the movable base 401, and the end of the connecting rod 403 away from the movable base 401 is slidably connected to a moving ring 501. The connecting rod 403 can pull the moving ring 501 to move left and right, and the connecting rod 403 does not affect the rotation of the moving ring 501 within the frame 101. The cylinder 402 enables the movable seat 401 to move left and right within the frame 101. The movable seat 401 drives the mounting block 405 to move via the servo motor 404. The mounting block 405 drives the mounting cylinder 301 and the clamping cylinder 302 to move a certain distance relative to the docking seat 201, causing the second conical surface 304 to shift relative to the first conical surface 203. The docking seat 201 and the clamping cylinder 302 press against each other, reducing the size of the receiving groove 303 on the clamping cylinder 302. When installing the workpiece, the end of the clamping cylinder 302 retracts to fix the workpiece.

[0033] In this embodiment, a servo motor 404 is bolted to the movable base 401, and a mounting block 405 is bolted to the output end of the servo motor 404. One end of the mounting cylinder 301 has a thread on its inner side, and the outer circumferential surface of the mounting block 405 has a thread that mates with the mounting cylinder 301. When the mounting cylinder 301 is installed, the operator inserts the mounting cylinder 301 into the insertion interface 202 of the docking seat 201, and the inner thread of the mounting cylinder 301 mates with the mounting block 405. The servo motor 404 is controlled to drive the mounting block 405 to rotate, so that the mounting cylinder 301 is mounted on the mounting block 405.

[0034] Working Principle: Before use, the appropriate mounting cylinder 301 and clamping cylinder 302 need to be selected based on the workpiece to be milled. When mounting the mounting cylinder 301 onto the docking seat 201, the operator aligns the mounting cylinder 301 with the insertion interface 202 of the docking seat 201 and inserts it. During the process of the mounting cylinder 301 entering the insertion interface 202, one end of the mounting cylinder 301 reaches the position of the mounting block 405. At this time, the servo motor 404 is activated, driving the mounting block 405 to rotate. During this process, the operator rotates the mounting cylinder 301 so that the straight groove 305 on the mounting cylinder 301 aligns with the limiting block 503. As the mounting block 405 rotates, the thread on the inner wall of the mounting cylinder 301 will engage with the external thread of the mounting block 405. During installation, due to the engagement of the straight groove 305 and the limiting block 503, the mounting cylinder 301 will not rub against the mounting block 405. The rotation improves installation accuracy. After installation, the cylindrical workpiece to be milled needs to be placed at the end of the clamping cylinder 302. The operator only needs to insert the workpiece into the clamping cylinder 302 and turn on the cylinder 402. The output end of the cylinder 402 retracts a certain distance, and the cylinder 402 causes the moving seat 401 to move closer to the cylinder 402 inside the frame 101. The moving seat 401 drives the mounting cylinder 301 and the clamping cylinder 302 to move a certain distance relative to the docking seat 201 through the servo motor 404 and the mounting block 405. During this process, the second cone surface 304 is displaced relative to the first cone surface 203. The docking seat 201 and the clamping cylinder 302 squeeze each other, thereby shrinking the end of the clamping cylinder 302 and reducing the receiving groove 303 on the clamping cylinder 302 to fix the outer periphery of the workpiece. At the same time, the moving seat 401 drives the moving ring 501 to move through the connecting rod 403. The moving ring 501 drives the clamping block 505 to move, causing the clamping block 505 to be misaligned with the clamping shaft 506, thus releasing the restriction on the rotation of the moving ring 501 within the frame 101. At this time, the servo motor 404 drives the mounting block 405 to rotate. The mounting block 405 can drive the mounting cylinder 301, the clamping cylinder 302, and the workpiece clamped inside to rotate, which facilitates the milling cutter assembly 104 to mill the outer peripheral surface of the workpiece. After the machining is completed, the cylinder 402 pushes out a certain distance to unload the machined workpiece. The unmachined workpiece is then installed in the same way, and the milling operation is performed in this manner.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
