Description

Technical Field

[0001] This invention relates to the field of rotor commutator processing technology, and more specifically, to a lathe apparatus for processing rotor commutators. Background Technology

[0002] Rotor commutators are widely used in various types of motors. They are components that can change the direction and speed of motor operation and are usually mounted on the shaft of the motor rotor. When the motor needs to change its direction of operation, it reverses the direction of the current through the rotor commutator, thus changing the direction of motor rotation.

[0003] In the field of rotor commutator machining, rough turning and finish turning are often required to ensure machining accuracy. In existing technologies, both rough turning and finish turning require a cutting table to support rotor rotation and facilitate the cutting operation of the commutator. To avoid the splashing of chips during cutting, most existing technologies use a suction connecting pipe on one side of the cutting table. This design facilitates rotor placement and chip removal from the cutting space. However, since the cutting space is relatively open, the suction connecting pipe has limited chip removal capacity and cannot fully remove chips. Therefore, considering the problem of insufficient chip removal, a top cover plate is usually used to close the open cutting space. With this structural design, manual closure is cumbersome and inefficient; mechanical closure occupies too much machining space, easily conflicts with the rotor transport mechanism, and requires consideration of obstacle avoidance. The structural design is not reasonable, and the linkage and coordination of machining are insufficient. Summary of the Invention

[0029] This invention provides a lathe for machining rotor commutators, such as... Figures 1 to 7 As shown, the lathe includes a material handling device 1, a roughing device 2, a finishing device 3, a cleaning device 4, and a vision inspection device. The material handling device 1 is used to pick up and place the rotor 10 to transfer it to the roughing device 2, the finishing device 3, the cleaning device 4, or the vision inspection device. The roughing device 2 includes a roughing tool, a first multi-axis moving mechanism 22, and a first pressing and rotating mechanism 23. The first pressing and rotating mechanism 23 is used to limit the pressing rotor 10 and drive the rotor 10 to rotate so that the commutator 20 rotates synchronously. The first multi-axis moving mechanism 22 is used to drive the roughing tool to rotate in multiple directions relative to the commutator 20. The moving, roughing tool is used for rough turning of the commutator 20; the finishing device 3 includes a finishing tool, a second multi-axis moving mechanism 32 and a second pressing and rotating mechanism 33. After rough turning, the second pressing and rotating mechanism 33 is used to limit the pressure cover rotor 10 and drive the rotor 10 to rotate so that the commutator 20 rotates synchronously. The second multi-axis moving mechanism 32 is used to drive the finishing tool to move in multiple directions relative to the commutator 20. The finishing tool is used for finishing turning of the commutator 20; the cleaning device 4 is used to clean the waste on the finishing turned commutator 20; the vision inspection device is used to inspect the appearance of the cleaned commutator 20.

[0030] In this embodiment, the first pressing and rotating mechanism 23 includes a first pressing belt assembly 231 and a first pressing table 232. The first pressing belt assembly 231 includes a bracket 2310, which is in the shape of an "I". The upper arm of the bracket 2310 is a plate with one side upright. A first motor 2311 and a first rotating shaft 2312 are respectively provided on its front side. The first rotating shaft 2312 is located to the right of the first motor 2311. The output end of the first motor 2311 is connected to the first rotating shaft 2312 through a first synchronous belt 2313, so that the first rotating shaft 2312 can be driven to rotate by the first motor 2311. The lower arm of the bracket 2310 is a horizontally arranged plate with a telescopic cylinder 2314 located below the first motor 2311. The output end of the telescopic cylinder 2314 faces upward and is hinged to a drive rod 2316. A mounting plate 2317 is provided on the drive rod 2316. Specifically, the output end of the telescopic cylinder 2314 is equipped with a push rod 2315, which is inclined towards the mounting plate 2317; the upper end of the push rod 2315 is hinged to the drive rod 2316. It should be noted that, to ensure the telescopic cylinder 2314 controls the push rod 2315 in the same direction, the telescopic cylinder 2314 can be tilted so that the push rod 2315 tilts towards the mounting plate 2317, thus ensuring that the push rod 2315 moves along the telescopic direction of the telescopic cylinder 2314. The left and right sides of the mounting plate 2317 are both convex arc-shaped. One end of the drive rod 2316 is integrally connected to the left side of the mounting plate 2317, and the other end of the drive rod 2316 is hinged to the push rod 2315. An arc-shaped limiting ring is also provided on the front side of the mounting plate 2317 near its left side. One end of the first rotating shaft 2312 is located inside the arc-shaped limiting ring, serving to protect the first rotating shaft 2312.

[0031] The mounting plate 2317 has a first driven wheel 2318 on its right side of the front side. One end of a first rotating shaft 2312 passes through the front end of the mounting plate 2317 and is located to the left of the first driven wheel 2318, and is connected to the first driven wheel 2318 via a second synchronous belt 2319. Specifically, the mounting plate 2317 has a through hole for the first rotating shaft 2312 to pass through. A bearing is installed in the through hole, and the first rotating shaft 2312 is fitted onto the inner ring of the bearing. The outer ring of the bearing is fixed in the through hole of the mounting plate 2317. The telescopic cylinder 2314 drives the drive rod 2316 to move, causing the drive rod 2316 to swing the mounting plate 2317 up and down. The first motor 2311 drives the first rotating shaft 2312 to rotate, which in turn drives the second synchronous belt 2319 to move.

[0032] The mounting plate 2317 has a first cover 233 on its front side near the lower edge of the second synchronous belt 2319. When the first cover 233 cooperates with the first pressure table 232 to limit and press the rotor 10 inside, the lower edge of the second synchronous belt 2319 abuts against the rotor 10 to drive the rotor 10 to rotate. Furthermore, the mounting plate 2317 has a first lifting mechanism 234 on its rear side. The output end of the first lifting mechanism 234 has a connecting rod, which is perpendicular to the first lifting mechanism 234. One end of the connecting rod passes through the front end of the mounting plate 2317 and is located between the first rotating shaft 2312 and the first driven wheel 2318. The mounting plate 2317 has a corresponding first clearance notch for the connecting rod to pass through, facilitating the vertical movement of the connecting rod. One end of the connecting rod has a roller 235. The output end of the first lifting mechanism 234 presses down to move the roller 235 towards the first pressure table 232. When the rotor 10 is placed on the first pressing table 232, the roller 235 corresponds to the rotor 10, and the lower edge of the second synchronous belt 2319 is located between the roller 235 and the rotor 10. Under the force of the roller 235, the rotor 10 can be driven to rotate stably by the second synchronous belt 2319. The first lifting mechanism 234 adopts a lifting cylinder.

[0033] Specifically, the first pressing table 232 includes a fixed base 2321, which is located below the first cover 233. A second lifting mechanism 2322 is provided on the fixed base 2321, and a lifting platform 2323 is provided at the output end of the second lifting mechanism 2322. The lifting platform 2323 supports the rotation of the rotor 10. The second lifting mechanism 2322 drives the lifting platform 2323 to different heights, thereby adjusting the height of the rotor 10. This allows for adjustments to the height at which the first cover 233 and the lifting platform 2323 are aligned, as well as the height at which the rotor 10 abuts against the second synchronous belt 2319, to suit different processing scenarios. The second lifting mechanism 2322 also employs a lifting cylinder.

[0034] Specifically, a second clearance recess is provided on the lower edge of the first cover 233 for the rotor 10 shaft to extend out, which helps to reduce the volume of the first cover 233, avoid occupying too much space, and also facilitates limiting one end of the rotor 10. A third clearance recess is provided on the other lower edge of the first cover 233 for the rotor 10 to partially extend out, so that the rotor 10 can partially extend out and abut against the second synchronous belt 2319, thereby facilitating limiting the other end of the rotor 10 and helping the rotor 10 to rotate. The third clearance recess is opposite to the second clearance recess. The first cover 233 is also provided with a first exhaust pipe 236, one end of which is connected to the inside of the first cover 233, and the other end of which is connected to an industrial vacuum cleaner to achieve the purpose of exhausting waste.

[0035] In this embodiment, the second pressing and rotating mechanism 33 is the same as the first pressing and rotating mechanism 23. Therefore, the structure of the second pressing and rotating mechanism 33 can be referred to the aforementioned description of the first pressing and rotating mechanism 23, and will not be repeated here.

[0036] In this embodiment, the cleaning device 4 includes a translational pressing assembly 41 and a second pressing platform 42. The translational pressing assembly 41 includes a horizontally arranged slide rail 411, on which a slider 412 slides, and the slider 412 is also driven to slide by a motor. The second pressing platform 42 is also used to support the rotation of the rotor 10. A pressing cylinder 413 is provided on the slider 412, and a first vertical plate 414 is provided at the output end of the pressing cylinder 413. A second pressing belt assembly is provided on the first vertical plate 414. The second pressing belt assembly is used to abut against the rotor 10 to drive the rotor 10 to rotate, thereby causing the waste debris on the commutator 20 to fly out.

[0037] Specifically, the second pressure belt assembly includes a second motor 431. The fixed end of the second motor 431 is located on the rear side of the first upright plate 414, and the output end of the second motor 431 extends to the front end of the first upright plate 414 and is provided with a second rotating shaft 432. Two second driven wheels 433 are also provided on the front side of the first upright plate 414. The two second driven wheels 433 are at the same height and are located below the second rotating shaft 432 and are arranged in an equilateral triangle with the second rotating shaft 432. The second rotating shaft 432 and the two second driven wheels 433 are connected by a third synchronous belt 434. The lower edge of the third synchronous belt 434 is used to abut against the rotor 10 to drive the rotor 10 to rotate.

[0038] Specifically, a second upright plate 435 is provided on one side of the first upright plate 414, and the second upright plate 435 is perpendicular to the first upright plate 414; a cleaning space for accommodating the second pressing table 42 is formed between the second upright plate 435 and the first upright plate 414, and the second rotating shaft 432 and the two second driven wheels 433 are all located in the cleaning space. A third motor 436 is provided at the bottom of the second upright plate 435, and a brush 437 is provided at the output end of the third motor 436. The brush 437 is located in the cleaning space, and the third motor 436 drives the brush 437 to rotate to clean the waste debris present in the gap of the commutator 20. A second cover (not shown in the attached drawing) is provided between the first vertical plate 414 and the second vertical plate 435 within the cleaning space. The second cover (not shown in the attached drawing) has two side baffles and a top plate. The two side baffles and the top plate together with the first vertical plate 414 and the second vertical plate 435 form a cavity for covering the rotor 10. For example, it is similar in shape to the first cover 233 shown in the figure. The edge of one side baffle should also be provided with a relief notch for the shaft of the rotor 10 to extend out. When it is in place with the second pressing table 42, the rotor 10 is located inside it, and the shaft of the rotor 10 extends out of the corresponding relief notch. The lower edge of the third synchronous belt 434 abuts against the rotor 10, and the brush 437 is located above the commutator 20, so that when the rotor 10 drives the commutator 20 to rotate, the brush 437 cleans the waste in the surface and gaps of the commutator 20. Furthermore, a second exhaust pipe (not shown in the attached figure) may also be provided on the top plate. One end of the second exhaust pipe (not shown in the attached figure) is connected to the inside of the second cover (not shown in the attached figure), and the other end of the second exhaust pipe (not shown in the attached figure) is connected to an industrial vacuum cleaner, for example, with the same structural layout as the first exhaust pipe 236 shown in the figure, so as to achieve the purpose of exhausting waste.

[0039] In this embodiment, the visual inspection device includes a viewing window 51, a camera 52, and a positioning base 53. The camera 52 and the positioning base 53 are located on opposite sides of the viewing window 51. The positioning base 53 is equipped with a rotating seat 531, and the rotating seat 531 is equipped with an arc-shaped baffle 5311. The inner side of the arc-shaped baffle 5311 is equipped with a magnetic attraction element for positioning the rotor 10. Specifically, the rotating seat 531 rotates through a rotating mechanism located inside the positioning base 53. The rotating mechanism is, for example, a rotary motor, which drives the rotating seat 531 to rotate. When the rotor 10 is magnetically attracted to the arc-shaped baffle 5311, the commutator 20 is located above the arc-shaped baffle 5311, and the lens of the camera 52 is opposite to the commutator 20 through the viewing window 51. When the rotating seat 531 rotates 360°, it facilitates the camera 52 to perform visual inspection of the commutator 20, so as to quickly confirm whether the processed product meets the production requirements.

[0040] It should be noted that in this embodiment, both the first multi-axis moving mechanism 22 and the second multi-axis moving mechanism 32 adopt XY-axis moving drive mechanisms. XY-axis moving drive mechanisms are relatively existing. In practical applications, any suitable existing XY-axis moving drive mechanism can be used, and no specific limitation is made here. The material handling device 1 can be an existing robot with vertical and horizontal placement functions, as long as it can achieve the purpose of picking up and placing the rotor 10 in a vertical or horizontal posture.

[0041] In practical applications, the material handling device 1, roughing device 2, finishing device 3, cleaning device 4, and vision inspection device in this embodiment can all be mounted on the same machine tool 30. When the roughing device 2 and finishing device 3 are positioned on opposite sides of the material handling device 1, the material handling operation is facilitated. Placing the cleaning device 4 and vision inspection device close to the finishing device 3 facilitates the cleaning and vision inspection of the commutator after finishing machining, thus enabling coordinated processing between the various devices through a reasonable layout.

[0042] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
