Technical Field

[0001] The utility model relates to the technical field of gear processing, in particular to an auxiliary detection device for gear processing. Background Art

[0002] Gears refer to mechanical components with teeth on the wheel rim that can continuously mesh to transmit motion and power. Usually, during the gear processing process, they undergo pre-heating gear making and hot processing to post-heating processes. The disc gears are turned on the lathe to turn the end face and grind the inner and outer circles to the gear grinding process.

[0003] When the disc is being ground, the expansion sleeve is used to expand and clamp the inner hole of the disc. When the disc is placed manually, some debris may be attached to the inner hole of the disc. When the disc is placed, the expansion sleeve is used to clamp the disc. Due to the debris attached to the inner hole of the disc, the disc will be skewed when clamped. The overall placement of the disc is tilted, and the gear teeth on the disc are skewed as a whole. The grinding tool moves according to the trajectory specified by the system, which may affect the overall grinding effect of the disc.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] An auxiliary detection device for gear processing, such as Figure 1 - Figure 7As shown, it includes a processing machine tool 1, on which a positioning seat 2 is fixedly installed, a positioning shaft 3 is fixedly installed on the positioning seat 2, and an expansion sleeve 4 is evenly and movably installed on the positioning shaft 3. After the gear is placed on the positioning seat 2, the expansion sleeve 4 can be expanded outward and abut against the inner wall of the gear to limit the gear. A balance detection component is arranged on the positioning seat 2. When the gear is placed on the positioning seat 2, the balance detection component can detect whether the gear is placed on the positioning seat 2 in a balanced manner. A mounting frame 5 is fixedly installed on the positioning seat 2, and a positioning detection component is arranged on the mounting frame 5. The positioning detection component can detect whether the gear is placed in place in the forward direction. This avoids the problem of the gear teeth height changing due to the inverted ends of the gear, which affects the subsequent gear processing; by providing a balance detection component, when the gear is fine-processed, after the gear is placed in place on the positioning seat 2, the expansion sleeve 4 positions the gear, and the balance detection component can detect whether the gear is placed in place on the positioning seat 2, to avoid the problem of the gear being skewed due to not being fully placed in place and affecting the subsequent gear processing. At the same time, after the gear is placed in place on the positioning seat 2, the positioning detection component can detect whether the gear is placed in place in the forward direction, to avoid the problem of the gear teeth position height changing due to the inverted gear, which affects the subsequent processing.

At this time, the detection plate 6 in contact with the gear is squeezed and moves downward. When the detection plate 6 moves downward, it contacts the first contact sensor 7. The first contact sensor 7 feeds back a signal to the control system, indicating that the gear is in place. If the gear is skewed, the gear fails to contact the detection plate 6 at the inclined position, then six detection plates 6 fail to contact the gear, and the six first contact sensors 7 fail to contact the detection plate 6. The control system does not receive the feedback signals of the six first contact sensors 7, which means that the gear is not placed in a balanced manner. The gear position is manually readjusted before subsequent processing to ensure the gear processing effect.

[0028] Furthermore, the positioning detection component includes a fixed sleeve 10, which is fixedly mounted on the mounting frame 5, a movable sleeve 11 is movably mounted inside the fixed sleeve 10, and the movable sleeve 11 can be extended to the outside of the fixed sleeve 10 by moving upward, a movable frame 12 is movably mounted inside the movable sleeve 11, and the movable frame 12 can be moved upward to the outside of the movable sleeve 11, a rotating arm 13 is rotatably mounted on the movable frame 12, the rotating arm 13 is driven by a servo motor, and the servo motor is electrically connected to the external controller, an extension arm 14 is movably mounted on the rotating arm 13, the extension arm 14 is driven by a hydraulic telescopic rod, and the hydraulic telescopic rod is electrically connected to the external controller, a contact block 15 is movably mounted on the extension arm 14, a second contact sensor 17 is fixedly mounted inside the extension arm 14, and the second contact sensor 17 is electrically connected to the external controller, a second spring 16 is fixedly mounted inside the extension arm 14, and one of the second springs 16 The end is fixedly connected with the contact block 15, a first gear 21 is rotatably installed on the fixed sleeve 10, a counter 22 is evenly fixedly installed on the first gear 21, the counter 22 is electrically connected to the external controller, a second gear 23 is rotatably installed on one side of the fixed sleeve 10, the second gear 23 is meshed with the first gear 21, the second gear 23 is driven by a servo motor, the servo motor is electrically connected to the external controller, when the second gear 23 rotates, it meshes with the first gear 21 and presses the corresponding counter 22, a screw rod 20 is rotatably installed on the fixed sleeve 10, the screw rod 20 is fixedly connected with the first gear 21, a lifting sleeve 18 is movably installed inside the fixed sleeve 10, the lifting sleeve 18 is movably connected with the screw rod 20, a threaded seat 19 is threadedly connected to the screw rod 20, the threaded seat 19 is slidably installed inside the fixed sleeve 10, the threaded seat 19 is fixedly connected with the lifting sleeve 18, and the lifting sleeve 18 is fixedly connected with the movable frame 12;By providing a positioning detection component, the gear is manually placed on the positioning seat 2, and the size information of the gear is input into the control system. According to the height of the gear after being placed on the positioning seat 2, the servo motor is controlled to drive the second gear 23 to rotate. When the second gear 23 rotates, it meshes with the first gear 21 and drives the second spring 16 to rotate synchronously. When the second spring 16 rotates, it drives the lifting sleeve 18 to move upward and lifts the lifting sleeve 18 upward to the height of the rotating arm 13 and the upper end surface of the gear on the same horizontal plane. The servo motor is controlled to drive the rotating arm 13 to rotate so as to rotate the extension arm 14 to be vertical with the movable frame 12. According to the outer diameter of the gear teeth, the extension arm 14 is adjusted to be extended to be on the same vertical line with the outer diameter of the gear teeth. Finally, the servo motor is controlled to drive the second gear 23 to rotate in the opposite direction. Drive the extension arm 14 down, when the second gear 23 rotates, it can mesh with the first gear 21 and press the corresponding counter 22 to count. During the process of the extension arm 14 descending, it can contact the gear teeth on the gear at a certain position. The gear teeth contact and squeeze the contact block 15 and trigger the second contact sensor 17 to feedback the signal to the system. Synchronously, the system records the counting result of the counter 22 at the moment of contact with the gear teeth. If the gear is placed in place in the forward direction, the counting result of the counter 22 is correct. If the gear is not placed in place in the forward direction, the gear is inverted at this time. When the gear teeth contact the contact block 15 and trigger the feedback signal of the second contact sensor 17, the counting result of the counter 22 does not meet the standard, which means that the gear is inverted at this time. The gear is manually adjusted and then the subsequent gear processing is carried out to ensure the gear processing effect. ;

[0029] The working principle of the utility model is as follows: the size information of the gear is input into the control system, and after the gear is manually placed on the positioning seat 2, the gear contacts the detection plate 6 on the positioning seat 2. At this time, the detection plate 6 in contact with the gear is squeezed and moves downward. When the detection plate 6 moves downward, it contacts the first contact sensor 7. The first contact sensor 7 feeds back a signal to the control system, indicating that the gear is in place. If the gear is skewed, the gear fails to contact the detection plate 6 at the inclined position, and six detection plates 6 fail to contact the gear. The six first contact sensors 7 fail to contact the detection plates 6. The control system does not receive the feedback signals of the six first contact sensors 7, which means that the gear is not placed in a balanced manner. The gear position is manually readjusted, and the servo motor is controlled to drive the second gear 23 to rotate according to the height of the gear after it is placed on the positioning seat 2. When the second gear 23 rotates, it meshes with the first gear 21 and drives the second spring 16 to rotate synchronously. When the second spring 16 rotates, it drives the lifting sleeve 18 to move upward and lifts the lifting sleeve 18 upward to the height of the rotating arm 13 and the upper end surface of the gear. The servo motor drives the rotating arm 13 to rotate so as to rotate the extension arm 14 to be perpendicular to the movable frame 12. The extension arm 14 is extended to be perpendicular to the outer diameter of the gear teeth according to the outer diameter of the gear teeth. Finally, the servo motor drives the second gear 23 to rotate in the opposite direction to drive the extension arm 14 to descend. When the second gear 23 rotates, it can mesh with the first gear 21 and press the corresponding counter 22 to count. During the descent of the extension arm 14, it can contact the gear teeth on the gear at a certain position. The gear teeth contact and squeeze the contact block 15 and trigger the second contact sensor 17 to feedback a signal to the system. Synchronously, the system records the counting result of the counter 22 at the moment of contact with the gear teeth. If the gear is placed in place in the forward direction, the counting result of the counter 22 is correct. If the gear is not placed in place in the forward direction, the gear is inverted at this time. When the gear teeth contact the contact block 15 and trigger the feedback signal of the second contact sensor 17, the counting result of the counter 22 does not meet the standard, which means that the gear is inverted at this time. The gear is manually adjusted and the subsequent gear processing is carried out.
