Description

Technical Field

[0001] The utility model relates to the technical field of gear processing, in particular to a gear positioning drilling and grooving device. Background Art

[0002] The gear positioning drilling and grooving device is a device used for positioning, drilling and grooving on gears. It is usually composed of a positioning fixture and a drilling and grooving device to ensure that the holes and grooves on the gears are positioned accurately and precisely. It helps to improve production efficiency and product quality. In conjunction with publication number CN 218836815 U, publication date 2023.04.11, a gear positioning drilling and grooving device in a gear processing machine is disclosed.

[0003] In the prior art including the above patent, the motor is started again to make the rotating rod drive the gear plate to rotate. Since the clamping plate at one end of the rack clamps the processing gear, the rack cannot move at this time, so the rotating rod cannot rotate, and then the driven gear cannot rotate, so that the gear plate drives the entire rotating plate to rotate on the placement table through the rotating rod, and then adjusts other positions of the processing gear. However, the clamping plate used for clamping only increases the friction resistance through the inner friction pad, and due to the special structure of the teeth on the gear, there is point contact with the friction pad, and the contact area is small. When drilling, the rotational force generated by the drill may drive the gear to rotate and slide with the clamping plate, changing the drilling position of the gear. Utility Model Content

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] like Figure 1-6 As shown, a gear positioning drilling and grooving device comprises:

[0030] Rotate disk 1;

[0031] A holder 2 is arranged on a rotating disk 1 and is provided with a driving assembly to clamp the gear;

[0032] The holder 2 comprises:

[0033] A second fixed wedge 24 fixedly connected to the output end of the driving assembly and slidably disposed on the rotating disk 1;

[0034] A first fixed wedge 23 slidably disposed on the second fixed wedge 24;

[0035] A rotating stopper 25 is rotatably provided on the first fixed wedge 23 and the second fixed wedge 24 . The rotating stopper 25 is rotated by the gear to abut against the teeth.

[0036] The rotating block 25 is in a sector-shaped structure, and the first surface that contacts the gear is an arc surface, and the second surface and the third surface of the rotating block 25 are both provided with linearly arranged vertical grooves.

[0037] Specifically, two symmetrical sides of the first fixed wedge 23 extend along the tangent of the arc surface, and a plurality of clampers 2 are arranged on the rotating disk 1 in a circular array.

[0038] Furthermore, the gear to be processed is placed on the rotating disk 1, and the driving assembly is started so that the clamp 2 approaches the center of the rotating disk 1 and gradually abuts against the gear. Since the cross-sections of the first fixed wedge 23 and the second fixed wedge 24 are both trapezoidal, when the first surfaces of the first fixed wedge 23 and the second fixed wedge 24 are in contact with the tooth surface, the gear is rotated slightly under the guiding action of the inclined surface until the first surfaces of the first fixed wedge 23 and the second fixed wedge 24 abut against and are fixed to the tooth root of the gear; when the gear rotates during the drilling process, friction resistance is generated between the tooth root and the arc surface of the rotating stop block 25, so that the rotating stop block 25 rotates in the first fixed wedge 23 and the second fixed wedge 24, thereby causing the vertical groove to abut against the tooth surface. Since the vertical groove is relatively rough, the tooth surface can be effectively prevented from sliding.

[0039] In the above technology, through the structural design of the first fixed wedge 23 and the second fixed wedge 24, the first surfaces of the first fixed wedge 23 and the second fixed wedge 24 automatically slide into the tooth root of the gear and are fixed; when the gear rotates during the drilling process, the rotating stop block 25 rotates in the first fixed wedge 23 and the second fixed wedge 24, so that the vertical groove and the tooth surface are abutted. Since the vertical groove is relatively rough, the tooth surface can be effectively prevented from sliding.

[0040] As an embodiment further provided by the present invention, a guide sliding surface 21 is obliquely provided on the first fixed wedge 23 , and a tension spring is provided between the first fixed wedge 23 and the second fixed wedge 24 .

[0041] Specifically, in the process of the clamp 2 moving toward the gear, the guide surface 21 abuts against the upper side of the gear and slides, thereby driving the first fixed wedge 23 to slide upward. At this time, the tension spring causes the first fixed wedge 23 and the second fixed wedge 24 to have a tendency to move toward each other, so that the first fixed wedge 23 presses the gear downward, so that the first fixed wedge 23 can adapt to the heights of different gears. At the same time, the accordion rubber pad 22 folds and contracts under pressure to prevent the first fixed wedge 23 from exerting excessive pressure on the gear. At the same time, the accordion rubber pad 22 provides friction resistance to further prevent the gear from rotating.

[0042] As another embodiment further provided by the present invention, a balancing platform 3 is arranged on the rotating disk 1, and the balancing platform 3 abuts against the axis of the gear through a fixedly arranged cylinder and keeps synchronous movement.

[0043] Specifically, the cylinder of the balancing platform 3 fixes the axis of the gear, and under the adjustment of the gear's own gravity, the balancing platform 3 drives the gear to remain horizontal. When the gear rotates, the sliding friction between the balancing platform 3 and the rotating disk 1 is small, and the gear rotates in cooperation with the clamp 2, so that the clamp 2 is stuck in the root of the tooth to prevent the gear from being skewed when placed.

[0044] As another embodiment further provided by the present invention, a plurality of balls 31 are rotatably arranged on the side of the balancing platform 3 , an arc surface 11 is arranged on the inner wall of the rotating disk 1 , and the balls 31 are slidably arranged on the arc surface 11 .

[0045] Specifically, when the gear is placed on the balancing platform 3, the gravity of the gear makes the balancing platform 3 no longer horizontal. Then, the rolling friction between the ball 31 and the arc surface 11 eliminates the impact force caused by gravity, so that the balancing platform 3 returns to a horizontal state through its own gravity and the weight of the counterweight block 32 arranged at the bottom, thereby driving the gear to return to a horizontal state and avoiding vertical deviation during the gear placement process.

[0046] Working principle: the gear to be processed is placed on the balancing table 3 on the rotating disk 1, and the cylinder of the balancing table 3 fixes the axis of the gear. When the gear is placed on the balancing table 3, the gravity of the gear makes the balancing table 3 no longer horizontal, and then the rolling friction between the ball 31 and the arc surface 11 eliminates the impact force caused by gravity, so that the balancing table 3 restores to a horizontal state through its own gravity and the weight of the counterweight block 32 arranged at the bottom, thereby driving the gear to restore to a horizontal state and avoiding vertical deviation during the placement of the gear. Then, the driving assembly is started to make the clamp 2 approach the center of the rotating disk 1 and gradually abut against the gear. Since the cross-sections of the first fixed wedge 23 and the second fixed wedge 24 are both trapezoidal, when the first surfaces of the first fixed wedge 23 and the second fixed wedge 24 are in contact with the tooth surface, the gear rotates slightly under the guiding and sliding action of the inclined surface until the first fixed wedge 23 and the second fixed wedge 24 are in contact with the tooth surface. One side is against and fixed with the tooth root of the gear. In the process of the clamp 2 moving toward the gear, the guide sliding surface 21 is against and slides with the upper side of the gear, thereby driving the first fixed wedge 23 to slide upward. At this time, the tension spring makes the first fixed wedge 23 and the second fixed wedge 24 have a tendency to move toward each other, so that the first fixed wedge 23 presses the gear downward, so that the first fixed wedge 23 can adapt to the height of different gears. At the same time, the accordion pleated rubber pad 22 folds and contracts under pressure to prevent the first fixed wedge 23 from exerting excessive pressure on the gear. At the same time, the accordion pleated rubber pad 22 provides friction resistance to further prevent the gear from rotating. When the gear rotates during the drilling process, the tooth root and the arc surface of the rotating stop block 25 generate friction resistance, so that the rotating stop block 25 rotates in the first fixed wedge 23 and the second fixed wedge 24, so that the vertical groove is against the tooth surface. Since the vertical groove is relatively rough, the tooth surface can effectively prevent sliding.

[0047] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
