Technical Field

[0001] This utility model belongs to the technical field of gear processing equipment, and relates to an automated gear cutting fixture device. Background Technology

[0002] Automated gear cutting fixture equipment, through an automated control system, can accurately position and firmly clamp gears, ensuring that the gears remain stable and do not shift during the cutting process. The high-precision positioning and clamping technology effectively reduces machining errors and guarantees the machining accuracy of gears, and is widely used in gear production in many industries such as automobiles and machinery manufacturing.

[0003] Chinese patent publication number CN215545537U discloses a gear cutting fixture, including a support base. The upper end face of the support base is fixedly connected to the lower end face of a positioning frame with an L-shaped cross-section. The right side of the upper end face of the positioning frame is fixedly connected to a mounting plate with a T-shaped cross-section. The horizontal part of the mounting plate is engaged with a mounting groove opened on the lower end face of the mounting frame. Two limiting grooves are symmetrically opened on the inner wall of the mounting groove. The limiting grooves are slidably connected to a limiting plate. The upper end face of the limiting plate is tightly fitted with the lower end face of the horizontal part of the mounting plate. The lower end face of the limiting plate is rotatably connected to one end of a fastening bolt. The other end of the fastening bolt passes through the mounting frame and is threadedly connected to the mounting frame. The mounting frame is threadedly connected to a threaded rod. One end of the threaded rod passes through the vertical part of the mounting frame and is detachably connected to one end of a limiting head. The limiting head is engaged with a positioning hole opened on one side end face of the positioning frame.

[0004] In the gear cutting fixture provided by this patent, the horizontal part of the mounting plate is connected to the mounting groove by a snap-fit ​​method. The fit gap at the snap-fit ​​may cause the mounting plate to be inaccurately positioned, thereby affecting the tool installation accuracy and ultimately affecting the gear cutting precision.

The second slider 26 is slidably connected to the second slide rail 25. The upper end of the second slider 26 is fixedly connected to a tool mounting bracket 4 by bolts. The tool mounting bracket 4 can move along the second slide rail 25 with the second slider 26 to realize the position adjustment of the tool in another horizontal direction, thereby meeting the cutting position requirements of gears of different specifications.

[0017] like Figures 1 to 2 As shown, a mounting side plate 11 is welded and fixed to one side of the frame 1. A slot 111 is provided at the lower end of the mounting side plate 11, and several reinforcing plates 12 are welded and fixed to the outer side of the mounting side plate 11. A cylinder mounting plate 13 is welded and fixed between the reinforcing plates 12. One end of the cylinder body of the first drive cylinder 24 passes through the slot 111 of the mounting side plate 11 and is fixedly connected to the cylinder mounting plate 13 by bolts. The first drive cylinder 24 has a first piston rod 241 extending out. A connecting plate 14 is fixedly installed on the other side of the frame 1 by bolts. The end of the first piston rod 241 is connected to the lower end of the connecting plate 14. When the first drive cylinder 24 is activated, the first piston rod 241 can drive the connecting plate 14, the slide plate 23, and the first slider 22 to move along the first slide rail 21, completing the first stage of horizontal drive. At the same time, one end of the cylinder body of the second drive cylinder 27 is bolted to The upper end of the connection 14 is fixedly connected. The second driving cylinder 27 extends with a second piston rod 271. The end of the second piston rod 271 is connected to a connecting joint 6. The other end of the connecting joint 6 is connected to one side of the tool mounting bracket 4 by a threaded engagement.

The movable side plates 31 extend downwards from the lower end of the clamp base assembly 3, and the lower end face of the extended end is at the same horizontal height as the lower end face of the slide plate 23 to ensure the stability of the clamp base assembly 3 when placed. The lower end of the movable side plates 31 is fixedly connected to a movable base plate 32 by bolts. A locking handle 33 is threadedly connected to the movable base plate 32. When it is necessary to adjust the position of the clamp base assembly 3 on the slide plate 23, the locking handle 33 can be loosened to push the clamp base assembly 3 to move. After adjustment, the locking handle 33 is tightened. The clamp base assembly 3 is fixed by the clamping action between the locking handle 33 and the slide plate 23. The operation is convenient and the positioning is reliable.
