Description

Technical Field

[0001] The utility model relates to a field, in particular to a full-automatic milling and weight-removing balancing machine for brake discs. Background Art

[0002] The brake disc is an important component in the automobile braking system. When the surface unbalance degree is relatively high, it will affect the normal driving of the automobile and even cause safety accidents. Therefore, when processing the brake disc, it is usually necessary to detect its balance degree. At the same time, for the brake disc with a relatively high unbalance degree, it is necessary to perform weight-removing milling processing on it, and re-inspect it again after the processing is completed until the detection is qualified.

[0003] Chinese Patent with the publication number CN104374524A discloses a full-automatic weight-removing balancing machine for brake discs, which includes a base, a balance measurement and positioning mechanism, a milling mechanism, and a rotary arc feed mechanism.

The milling mechanism is fixedly connected to the base, and the milling end of the milling mechanism corresponds to the rotary arc feed mechanism. The balance measurement and positioning mechanism is arranged at the center of the rotary arc feed mechanism and is used to perform balance positioning detection on the brake disc. The present invention uses the balance measurement mechanism to perform automatic balance positioning detection on the brake disc. At the same time, it uses the milling mechanism to perform milling and weight-removing on the brake disc. After the milling is completed, the balance measurement and positioning mechanism is used to re-inspect the brake disc again, replacing manual operation, thereby greatly reducing the labor intensity of workers, improving the processing efficiency, ensuring the stable processing quality of the brake disc, high processing accuracy, and using various sensors to effectively monitor the processing process.

[0034] The positioning and rotating mechanism is arranged on the top of the workbench 1 and between the detection mechanism and the milling device 2, and is used to automatically rotate to enable the detection mechanism to conduct a comprehensive inspection.

[0036] The mounting frame 301 is arranged on the top of the workbench 1, the computer 302 is arranged on the top of the mounting frame 301, the balance detector 303 is arranged at the bottom of the computer 302, and the balance detector 303 is directly above the side of the positioning and rotating mechanism close to the milling device 2. In this way, with the rotation of the positioning and rotating mechanism, a comprehensive inspection of the brake disc can be carried out.

[0037] Embodiment 2

[0038] As Figures 3 - 5 shown, a full-automatic milling and weight-removing balance machine for brake discs proposed by the present utility model, compared with Embodiment 1, details the structure of the positioning and rotating mechanism in this embodiment.

[0039] The positioning and rotating mechanism includes a workpiece 403, a support assembly, a rotating assembly, and an emergency stop assembly; the rotating assembly is arranged on the top of the workbench 1 and is used to drive the brake disc to rotate continuously; the support assembly is rotatably arranged on the top of the rotating assembly and is used to fix the position of the workpiece 403 so that it does not deviate; the emergency stop assembly is arranged at the bottom of the workbench 1 and is used to immediately stop the rotation of the workpiece 403; the workpiece 403 is clamped on the outside of the support assembly. The support assembly includes a turntable 402, an empty slot 404, a first spring 405, a first straight slide rail 406, and a support block 407; the turntable 402 is rotatably arranged on the top of the rotating assembly, an empty slot 404 is arranged inside the turntable 402, the first straight slide rail 406 is arranged at the bottom of the empty slot 404, the support block 407 is slidably arranged on the first straight slide rail 406, the first spring 405 is arranged on the side of the support block 407 and the other end of the first spring 405 is connected to the inner side of the empty slot 404. Since through holes are provided at the axis of the brake disc workpiece 403 and the top of the support block 407 is an arc surface, when the through hole of the workpiece 403 is aligned with the arc surface of the support block 407 and pressed downward, there are three support blocks 407, and the three support blocks 407 will move towards each other at this time. At this time, the first spring 405 is stretched. After pressing the workpiece 403 to the bottom to contact the turntable 402, under the action of the first spring 405, the support block 407 can clamp the inner side of the workpiece 403 to prevent its position from deviating and affecting the detection. At the same time, different sizes of brake disc workpieces 403 can be clamped in this way. The rotating assembly includes a slide rail table 401, a motor 417, a connecting frame 418, a rotating shaft 416, a connecting ring 408, and a fixing plate 411; the connecting frame 418 is arranged at the bottom of the workbench 1, the motor 417 is arranged at the end of the connecting frame 418 away from the workbench 1, the rotating shaft 416 is arranged at the output end of the motor 417, a connecting rod 415 is arranged at the end of the rotating shaft 416 away from the motor 417, a mounting plate 414 is arranged at the end of the connecting rod 415, a second spring 413 is arranged inside the mounting plate 414, a power plate 412 is arranged at the end of the second spring 413 away from the mounting plate 414, and the bottom of the power plate 412 is rotatably connected to the end of the mounting plate 414; the slide rail table 401 is rotatably arranged at the bottom of the turntable 402 and the bottom of the slide rail table 401 is connected to the top of the workbench 1; the bottom of the connecting ring 408 is arranged at the bottom of the turntable 402, the fixing plate 411 is arranged inside the connecting ring 408, there are two fixing plates 411, and there is an overlapping part between the bottom of the fixing plate 411 and the top of the power plate 412. Since the second spring 413 is a strong spring, when the power plate 412 rotates to the fixing plate 411, it will drive the fixing plate 411 to rotate. The fixing plate 411 drives the connecting ring 408 to rotate, so that the connecting ring 408 drives the workpiece 403 to rotate continuously through the turntable 402, which is convenient for detection.The emergency stop assembly includes a second linear slide rail 409 and an electric slide rod 410; the second linear slide rail 409 is arranged at the bottom of the workbench 1, and the electric slide rod 410 is slidably arranged on the second linear slide rail 409. When the balance detector 303 detects that a certain part of the workpiece 403 is unqualified, it will send a signal to the computer 302, and the computer 302 controls the electric slide rod 410 to slide. The sliding distance is fixed. When the specified distance is not reached, the electric slide rod 410 will always move towards the specified point. Since there are multiple notches at the bottom of the connecting ring 408, and these notches are slightly larger than the electric slide rod 410, the electric slide rod 410 can be inserted into these notches, thereby jamming the position of the connecting ring 408 to make it stop, and the power plate 412 will rotate under the action of the second spring 413 and will not collide with the fixed plate 411 and cause damage.

[0040] In summary, when the present utility model is in use, since through holes are provided at the axis of the brake disc workpiece 403 and the top of the support block 407 is an arc surface, the through hole of the workpiece 403 is aligned with the arc surface of the support block 407 and pressed downward. There are three support blocks 407, and the three support blocks 407 will move towards each other at this time. At this time, the first spring 405 is stretched. After pressing the workpiece 403 to the bottom to contact the turntable 402, under the action of the first spring 405, the support block 407 can clamp the inner side of the workpiece 403 to prevent its position from shifting and affecting the detection. After fixing the brake disc workpiece 403, the motor 417 is started, the motor 417 drives the rotating shaft 416 to rotate, and the rotating shaft 416 drives the power plate 412 to rotate through the connecting rod 415. There is an overlapping part between the bottom of the fixed plate 411 and the top of the power plate 412. Since the second spring 413 is a strong spring, when the power plate 412 rotates to the fixed plate 411, it will drive the fixed plate 411 to rotate. The fixed plate 411 drives the connecting ring 408 to rotate, so that the connecting ring 408 drives the workpiece 403 to rotate continuously through the turntable 402. When the balance detector 303 detects that a certain part of the workpiece 403 is unqualified, it will send a signal to the computer 302, and the computer 302 controls the electric slide rod 410 to slide. The sliding distance is fixed. When the specified distance is not reached, the electric slide rod 410 will always move towards the specified point. The electric slide rod 410 can be inserted into these notches, thereby jamming the position of the connecting ring 408 to make it stop, and the power plate 412 will rotate under the action of the second spring 413 and will not collide with the fixed plate 411 and cause damage. Then, the milling device 2 is used to mill the brake disc workpiece 403 at this place to make it flat.

[0041] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to this. Various changes can be made without departing from the spirit of the present utility model within the knowledge scope of those skilled in the art.
