Description

Technical Field

[0001] The utility model relates to the field of spline milling equipment, in particular to a gear shaft spline milling device. Background Art

[0002] Milling refers to the use of a rotating multi-edged tool to cut a workpiece. It is a highly efficient processing method. During operation, the tool rotates as the main motion and the workpiece moves as the feed motion. The workpiece can also be fixed, but at this time the rotating tool must also move to complete the main motion and feed motion at the same time. Splines are a cylindrical mechanical connection part that is commonly used in many different mechanical and industrial applications, including vehicle engines, construction machinery, machine tools, manufacturing and other fields. In the production and manufacturing of gear shafts, splines are usually required to connect parts.

[0003] For example, the patent document with the announcement number CN212704601U discloses a high-precision gear shaft spline milling device. First, the first stepping screw fixes the first slider through a threaded connection, and the second stepping screw fixes the second slider through a threaded connection. During the milling process, the position of the gear shaft and the grinding tooth will not move, which improves the accuracy of the gear shaft spline. The gear shaft can be fixed in a fixed position and can mill the involute spline. The direction of the gear shaft can also be changed to a position parallel to the fixed rod by rotating the motor, and a thread can be milled, which increases the function of the device.

[0004] During use, the above patent can use the clamping block to limit the gear shaft and fix it with the fixing box, but it can only fix the gear shaft of a single size. Since there are many sizes of gear shafts in actual production, the above patent is not convenient for actual use. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figures 1-4 As shown, a gear shaft spline milling device includes a base 1, and a rotating mechanism for rotating in a horizontal plane and a milling mechanism 6 for processing are installed on the top of the base 1. The rotating mechanism is on one side of the milling mechanism 6. A lifting mechanism for adjusting the height is installed on the top of the rotating mechanism. A rotating mechanism for rotation is provided on the top of the lifting mechanism. The rotating mechanism includes a rotating disk 404, and a clamping mechanism for clamping and fixing is installed on the front side of the rotating disk 404.

[0025] The clamping mechanism includes a two-way screw 501, which is mounted on the front side of the rotating disk 404 through a bearing seat. Two threaded blocks 502 are threadedly connected to the two-way screw 501. A sliding groove 503 is provided on the front side of the rotating disk 404. The threaded block 502 is slidably connected to the sliding groove 503. A connecting plate 504 is welded on the front side of the threaded block 502. The bottom of the connecting plate 504 is connected to a clamping plate 505 by bolts. The clamping plate 505 is an arc-shaped plate made of gray cast iron. The gear shaft body 506 is clamped between the two clamping plates 505. The gear shaft body 506 is placed between the two clamping plates 505, and then the two-way screw 501 is rotated by the turntable, thereby driving the two threaded blocks 502 to approach each other along the sliding groove 503, thereby driving the two connecting plates 504 to move. The movement of the two connecting plates 504 drives the two clamping plates 505 to move, thereby clamping and fixing the gear shaft body 506, which can achieve clamping and fixing gears of different sizes. The top of the gear shaft 303 is connected to the upper and lower ends of the gear box 304, and the gear box 304 is connected to the lower end of the gear box 304 by screws.

[0026] The rotating mechanism includes a second motor 401, which is connected to the top of the top plate 303 by bolts. A fixed block 402 is welded to the top of the top plate 303. A rotating shaft 403 is rotatably connected to the fixed block 402 through a bearing. The output shaft of the second motor 401 is connected to the rear end of the rotating shaft 403 by a coupling. The rotating disk 404 is welded to the front end of the rotating shaft 403. The second motor 401 works to drive the rotating shaft 403 to rotate, thereby using the rotating disk 404 to drive the clamping mechanism to rotate, and then drive the gear shaft body 506 to rotate, and cooperate with the milling mechanism 6 to realize milling of the involute spline on the gear shaft body 506. The rotating mechanism includes a bottom plate 201, which is connected to the bottom plate 201 by bolts. The top of the seat 1 and the top of the base plate 201 are connected to the first motor 202 by bolts, and the output shaft of the first motor 202 is connected to the connecting disk 203 by a key. When milling of threads is required, the first motor 202 is operated to drive the connecting disk 203 to rotate, and the connecting disk 203 is rotated to drive the lifting mechanism to rotate, thereby utilizing the rotating mechanism to drive the clamping mechanism to rotate, and then driving the gear shaft body 506 to rotate, so as to rotate the gear shaft body 506 ninety degrees in the horizontal plane, so that the gear shaft body 506 is parallel to the rotating shaft where the grinding teeth in the milling mechanism 6 are located, and then the gear shaft body 506 is driven to rotate by the second motor 401, and cooperates with the milling mechanism 6 to realize milling of threads on the gear shaft body 506.

[0027] Working principle: When in use, the gear shaft body 506 is placed between the two clamping plates 505, and then the bidirectional screw 501 is rotated by the turntable, thereby driving the two threaded blocks 502 to approach each other along the sliding groove 503, and then driving the two connecting plates 504 to move. The movement of the two connecting plates 504 drives the two clamping plates 505 to move, thereby clamping and fixing the gear shaft body 506, which can achieve clamping and fixing gear shafts of different sizes, increasing the scope of use. Then, the hydraulic cylinder 302 works to drive the top plate 303 to rise and fall, and at the same time drive the support rod 305 to slide in the fixed column 304, so that the top plate 303 rises and falls more smoothly. The lifting of the top plate 303 can drive the rotating mechanism to rise and fall, thereby driving the gear shaft body 506 to rise and fall, and realize adjusting the height of the gear shaft body 506 so that the center of the gear shaft body 506 is aligned with the center of the milling mechanism 6. The grinding teeth are at the same height, which is convenient for processing. Then, the second motor 401 is operated to drive the rotating shaft 403 to rotate, so that the rotating disk 404 is used to drive the clamping mechanism to rotate, and then the gear shaft body 506 is driven to rotate, and the milling mechanism 6 is cooperated to realize milling of the involute spline on the gear shaft body 506. When thread milling is required, the first motor 202 is operated to drive the connecting disk 203 to rotate, and the connecting disk 203 is rotated to drive the lifting mechanism to rotate, so as to use the rotating mechanism to drive the clamping mechanism to rotate, and then the gear shaft body 506 is driven to rotate, so as to realize rotating the gear shaft body 506 ninety degrees in the horizontal plane, so that the gear shaft body 506 is parallel to the rotating axis where the grinding teeth are located in the milling mechanism 6. Then, the gear shaft body 506 is driven to rotate by the second motor 401, and the milling mechanism 6 is cooperated to realize milling of threads on the gear shaft body 506.
