Description

Technical Field

[0001] The present invention relates to the field of tapping of rotating shafts, and particularly to a tapping device for a motor rotating shaft. Background Art

[0002] As an indispensable power source in modern society, motors are widely used in various fields such as industry, agriculture, and daily life. As a key component of the motor, the machining accuracy and quality of the motor rotating shaft directly affect the performance and service life of the motor. Tapping, as an important process in the machining of the motor rotating shaft, aims to machine internal threads on the rotating shaft so as to cooperate with fasteners such as screws to achieve the connection and fixation of components.

[0003] According to the Chinese authorized patent publication number: CN110026624B, a tapping device for a motor rotating shaft is disclosed, which relates to the technical field of motor production. The key points of its technical solution are: including a bench tapping machine, the bench tapping machine includes a workbench; a sliding seat is slidably connected to the upper end surface of the workbench along the horizontal direction, an installation seat is arranged on the upper end surface of the sliding seat, a positioning groove for placing and positioning the workpiece is opened on the upper end surface of the installation seat, and a limiting component for tightly fixing the workpiece is also arranged on the sliding seat; a driving component for driving the sliding seat to move is also arranged on the workbench, and a positioning component is also arranged on the workbench, and the positioning component is located on one side of the sliding path of the sliding seat. When the driving component drives the sliding seat to slide and abut against the positioning component, the positioning groove is located below the tap of the bench tapping machine, so that the tap can be aligned with the circular groove of the workpiece for tapping. The setting of the sliding seat, the positioning groove and the limiting component makes the clamping and positioning of the workpiece more convenient, thus making the tapping operation more convenient, and also making the overall production efficiency higher. However, there are still deficiencies in this tapping device. The most directly worn part of the tapping tap is its cutting edge. As the rotating shaft material is continuously cut, the sharp cutting edge will gradually become dull and flat. The operator needs to regularly disassemble the tapping tap for visual inspection, or use special measuring tools to measure the size of its cutting part. This method cannot reflect the wear state in real time, and the process is cumbersome, which is likely to delay the replacement time. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a tapping device for a motor rotating shaft, which solves the above problems.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: A tapping device for a motor rotating shaft, comprising:

[0006] A tapping frame;

[0007] Rotating shaft tapping mechanism; the rotating shaft tapping mechanism is arranged on the left and right sides of the upper surface of the tapping frame. The rotating shaft tapping mechanism is used to tap the rotating shaft of the tapping motor while triggering the tapping depth marking line and cooperating with the standard tapping depth marking line length to detect the wear condition of the tapping cone. The rotating shaft tapping mechanism includes a connecting slide rail, a connecting slider, a tapping driving frame, a driving motor, a tapping cone, a linkage arm, an L-shaped fixing rod, a tapping depth prompt cylinder, a coloring rolling ball and a test screw head. The tapping electric push rod starts to act. The fixed end of the tapping electric push rod is fixed on the outer support foot, and its free end pushes the tapping driving frame. The rotating tapping cone is driven by the tapping driving frame to align with the surface of the motor rotating shaft and start to cut inward to form a thread. When the tapping cone cuts to the preset tapping depth, a specific structure on the linkage arm or the connecting ring will trigger a specific position of the tapping depth prompt cylinder. At this time, the red ink inside the prompt cylinder will contact the coloring rolling ball embedded in its inner side. Due to the rotation of the tapping cone, the coloring rolling ball also rolls, and rolls the red ink on a specific position of the motor rotating shaft to form a mark corresponding to the tapping depth. After the motor rotating shaft is tapped, the motor rotating shaft is rotated so that its tapping end is on the right side, and the test screw head is screwed into the threaded hole tapped on the left side. Observe the screwing depth and smoothness. At the same time, it can be observed whether the linkage mechanism on the right side can also trigger the marking during the screwing of the test screw head. By comparing the standard tapping depth marking line length (triggered by the left tapping) with the marking (or the non-triggered situation) triggered during the screwing of the test screw head, as well as the difficulty and depth of screwing the test screw head, the wear condition of the left tapping cone can be comprehensively judged. If the test screw head is difficult to screw in, the screwing depth is insufficient, or the marking line length does not match the standard, it indicates that the tapping cone may be worn and needs to be replaced;

[0008] Feeding guiding mechanism; the feeding guiding mechanism is arranged at the rear side of the upper surface of the tapping frame. The feeding guiding mechanism is used to automatically guide the motor rotating shaft to the tapping area.

[0009] Preferably, the number of the connecting slide rails is set to two.

[0010] Preferably, a linkage arm is fixedly connected to the upper surface of the tapping drive frame on the left side. One end of the linkage arm away from the tapping drive frame is fixedly connected to a connecting rod inside. One end of the connecting rod away from the tapping drive frame is fixedly connected to the outside of a connecting ring. One end of the connecting ring away from the L-shaped fixing rod is fixedly connected to a tapping depth reminder cylinder. A coloring ball is embedded on the inner surface of the tapping depth reminder cylinder. Red ink is filled inside the tapping depth reminder cylinder. One end of the connecting ring close to the L-shaped fixing rod is fixedly connected to an arc-shaped baffle.

[0011] Preferably, a test screw head is rotatably connected inside the tapping drive frame on the right side. A hand crank is arranged outside the tapping drive frame, and the hand crank is in transmission connection with the test screw head. A connecting ring is arranged behind the test screw head. A tapping depth reminder cylinder is arranged inside the connecting ring. The two tapping depth reminder cylinders on the left and right are symmetrically arranged alternately.

[0012] Preferably, the feeding guiding mechanism includes a support frame, a rotating shaft placement frame, an inclined guiding plate, a front baffle, a rotating shaft guiding platform, a protruding end, a V-shaped card slot, and a micro electric push rod. The rotating shaft placement frame is arranged on the upper surface of the tapping frame. Four corners of the outer surface of the rotating shaft placement frame are fixedly connected with support frames. The two support frames on the front side are lower than the two support frames on the rear side. The front end of the support frame is fixedly connected with a front baffle.

[0013] Preferably, an inclined guiding plate is fixedly connected to the front side of the front baffle. One end of the inclined guiding plate away from the front baffle is attached to the rear side of the upper surface of the rotating shaft limiting fixture and is fixedly connected to the upper surface of the rotating shaft guiding platform. A protruding end is fixedly connected to the front side of the rotating shaft guiding platform. A groove is opened at the rear side of the rotating shaft limiting fixture. The lower end of the rotating shaft limiting fixture is arranged on the upper surface of the tapping table. The lower end of the tapping table is fixedly connected to the upper surface of the tapping frame.

[0014] Preferably, V-shaped card slots are opened on the sides of the rotating shaft guiding platform and the rotating shaft limiting fixture close to each other. A motor rotating shaft to be tapped penetrates horizontally inside the V-shaped card slot.

[0015] Preferably, a limiting electric push rod is arranged in front of the rotating shaft limiting fixture. The free end of the limiting electric push rod is in transmission connection with the rotating shaft limiting fixture. The fixed end of the limiting electric push rod is fixedly connected to the upper surface of the outer support foot.

[0016] Preferably, the lower end of the tapping frame is fixedly connected to a fixed steel frame.

[0017] Preferably, a bearing is arranged in the middle of the connecting ring.

[0018] The present invention provides a tapping device for a motor rotating shaft. Compared with the prior art, the following beneficial effects are achieved:

[0019] 1. In the present invention, through the set spindle tapping mechanism, the tapping motor spindle to be tapped is placed and firmly fixed at a suitable position on the tapping frame. The driving motor on the left tapping driving frame starts to operate, and the tapping cone directly driven by its output end rotates at high speed. At the same time or later, the tapping electric push rod starts to act. The fixed end of the tapping electric push rod is fixed on the outer support foot, and its free end pushes the tapping driving frame. The rotating tapping cone, driven by the tapping driving frame, aligns with the surface of the motor spindle and starts to cut inwards to form a thread. When the tapping cone cutting reaches the preset tapping depth, a specific structure on the linkage arm or connecting ring will trigger a specific position of the tapping depth prompt cylinder. At this time, the red ink inside the prompt cylinder will contact the coloring ball embedded in its inner side. Due to the rotation of the tapping cone, the coloring ball also rolls, rolling the red ink on a specific position of the motor spindle to form a mark corresponding to the tapping depth. After the motor spindle is tapped, the motor spindle is turned around so that its tapping end is on the right side, and the test screw head is screwed into the threaded hole completed by the left tapping. Observe the screwing depth and smoothness. At the same time, it can be observed whether the linkage mechanism on the right can also trigger scribing during the screwing of the test screw head. By comparing the standard tapping depth scribing length (triggered by the left tapping) with the scribing (or the non-triggered situation) triggered when the test screw head is screwed in, as well as the difficulty and depth of screwing in the test screw head, the wear condition of the left tapping cone can be comprehensively judged. If the test screw head is difficult to screw in, the screwing depth is insufficient, or the scribing length does not match the standard, it indicates that the tapping cone may be worn and needs to be replaced. In this way, while completing the tapping, the depth mark is automatically triggered, and a supporting test screw head and a linkage detection mechanism are provided, which is convenient for quickly judging the state of the tapping cone. The operator can quickly judge whether the tapping cone needs to be replaced beside the equipment without using complex instruments, ensuring the tapping quality and the continuous and stable operation of the equipment;

[0020] 2. In the present invention, through the feeding guiding mechanism provided, the operator stacks the motor shafts that need to be tapped subsequently in the shaft placement rack. The micro electric push rod pushes the motor shaft at the front side position in the shaft placement rack. The micro electric push rod pushes the motor shaft upward so that its height is higher than the front baffle. Under the action of gravity, the shaft slides downward along the inclined plane guiding plate. After the shaft slides off the inclined plane guiding plate, it will enter the area of the shaft placement rack and continue to move forward until its shaft body is captured by the V-shaped card slots on both sides. The protruding end on the shaft guiding table helps to guide the shaft to more accurately enter the V-shaped card slots of the shaft limiting fixture. When the motor shaft is preliminarily positioned by the V-shaped card slots, the limiting electric push rod in the front starts to act. The fixed end of the limiting electric push rod is fixed on the outer support feet, and its free end pushes the shaft limiting fixture forward. The shaft limiting fixture moves forward, and the V-shaped card slots on it fit more closely with the V-shaped card slots of the shaft guiding table, thereby firmly clamping the motor shaft between the two V-shaped card slots to ensure its stable position during the tapping process. The feeding guiding mechanism realizes partial automation of the shaft from input to positioning and clamping, reduces manual handling and manual alignment operations, greatly reduces the labor intensity of the operator, and improves the automation level of the overall production line.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1-8 , the present invention provides two technical solutions, specifically including the following embodiments:

[0033] Embodiment 1: A tapping device for a motor shaft, comprising: a tapping frame 1; a shaft tapping mechanism 3; the shaft tapping mechanism 3 is arranged on the left and right sides of the upper surface of the tapping frame 1. The shaft tapping mechanism 3 is used to tap the motor shaft 4 to be tapped while triggering the marking of the tapping depth and detecting the wear condition of the tapping tap 305 in cooperation with the standard tapping depth marking length. The shaft tapping mechanism 3 includes a connecting slide rail 301, a connecting slider 302, a tapping driving frame 303, a driving motor 304, a tapping tap 305, a linkage arm 306, an L-shaped fixing rod 310, a tapping depth prompt cylinder 311, a coloring ball 312 and a test screw head 315. The number of connecting slide rails 301 is set to two, and the two connecting slide rails 301 are respectively fixedly connected to the left and right sides of the upper surface of the tapping frame 1. The upper surfaces of the left and right connecting slide rails 301 are both drivingly connected with a connecting slider 302. The upper surfaces of the two connecting sliders 302 are both fixedly connected with a tapping driving frame 303. Tapping electric push rods 7 are arranged on the outer sides of the two tapping driving frames 303. The free end of the tapping electric push rod 7 is drivingly connected with the tapping driving frame 303, and the fixed end of the tapping electric push rod 7 is fixedly connected to the upper surface of the outer support leg 6. The driving motor 304 is fixedly connected to the upper surface of the left tapping driving frame 303. The output end of the driving motor 304 is drivingly connected with the tapping tap 305. The linkage arm 306 is fixedly connected to the upper surface of the left tapping driving frame 303. The inner side of the end of the linkage arm 306 away from the tapping driving frame 303 is fixedly connected with a connecting rod 307. The end of the connecting rod 307 away from the tapping driving frame 303 is fixedly connected to the outer side of the connecting ring 308. The outer side of the end of the connecting ring 308 away from the connecting rod 307 is fixedly connected with an L-shaped fixing rod 310. The outer side of the end of the connecting ring 308 away from the L-shaped fixing rod 310 is fixedly connected with a tapping depth prompt cylinder 311. The inner surface of the tapping depth prompt cylinder 311 is embedded with a coloring ball 312. The tapping depth prompt cylinder 311 is filled with red ink inside. The outer side of the end of the connecting ring 308 close to the L-shaped fixing rod 310 is fixedly connected with an arc-shaped baffle 313. The test screw head 315 is rotatably connected to the inner side of the right tapping driving frame 303. A hand crank 314 is arranged on the outer side of the tapping driving frame 303, and the hand crank 314 is drivingly connected with the test screw head 315. A connecting ring 308 is arranged at the rear side of the test screw head 315. The tapping depth prompt cylinder 311 is arranged inside the connecting ring 308. The left and right tapping depth prompt cylinders 311 are symmetrically and alternately arranged. A bearing 309 is arranged in the middle of the connecting ring 308.

[0034] During operation, the rotating shaft 4 of the tapping motor to be processed is placed and firmly fixed at a suitable position on the tapping frame 1. The driving motor 304 on the left tapping driving frame 303 starts to operate, and the tapping tap 305 directly driven and connected to its output end rotates at a high speed. At the same time or shortly after, the tapping electric push rod 7 starts to act. The fixed end of the tapping electric push rod 7 is fixed on the outer support leg 6, and its free end pushes the tapping driving frame 303. The rotating tapping tap 305, driven by the tapping driving frame 303, aligns with the surface of the motor rotating shaft and starts to cut inward to form threads. When the tapping tap 305 cuts to the preset tapping depth, a specific structure on the linkage arm 306 or the connecting ring 308 will trigger a specific position of the tapping depth indicating cylinder 311. At this time, the red ink inside the indicating cylinder will contact the coloring ball 312 embedded in its inner side. Due to the rotation of the tapping tap 305, the coloring ball 312 also rolls, rolling the red ink onto a specific position of the motor rotating shaft to form a mark corresponding to the tapping depth. After the motor rotating shaft is tapped, the direction of the motor rotating shaft is reversed so that its tapped end is on the right side. The test screw head 315 is screwed into the threaded hole completed by the left tapping, and the screwing depth and smoothness are observed. At the same time, it can be observed whether the linkage mechanism on the right side can also trigger scribing during the screwing of the test screw head 315. By comparing the scribed line length triggered by the left tapping with the standard tapping depth with the scribing triggered or not triggered when the test screw head 315 is screwed in, as well as the difficulty and depth of screwing in the test screw head 315, the wear condition of the left tapping tap 305 can be comprehensively judged. If the test screw head 315 is difficult to screw in, the screwing depth is insufficient, or the scribed line length does not conform to the standard, it indicates that the tapping tap 305 may be worn and needs to be replaced. In this way, while completing the tapping, the depth mark is automatically triggered, and a supporting test screw head 315 and a linkage detection mechanism are provided, which facilitates quickly judging the state of the tapping tap 305. The operator can quickly judge whether the tapping tap 305 needs to be replaced beside the equipment without using complex instruments, ensuring the tapping quality and the continuous and stable operation of the equipment.

[0035] Embodiment 2: On the basis of Embodiment 1, there is a feeding guiding mechanism 5; the feeding guiding mechanism 5 is arranged at the rear side of the upper surface of the tapping frame 1, and the feeding guiding mechanism 5 is used to automatically guide the motor rotating shaft to the tapping area. The feeding guiding mechanism 5 includes a support frame 501, a rotating shaft placement frame 502, an inclined surface guiding plate 503, a front baffle 504, a rotating shaft guiding platform 505, a convex end 506, a V-shaped card slot 507, and a micro electric push rod 508. The rotating shaft placement frame 502 is arranged on the upper surface of the tapping frame 1, and support frames 501 are fixedly connected to the four corners of the outer surface of the rotating shaft placement frame 502. The heights of the two front support frames 501 are lower than those of the two rear support frames 501. The front end of the support frame 501 is fixedly connected to the front baffle 504, and the inclined surface guiding plate 503 is fixedly connected to the front side of the front baffle 504. One end of the inclined surface guiding plate 503 away from the front baffle 504 is attached to the rear side of the upper surface of the rotating shaft limiting fixture 9 and is fixedly connected to the upper surface of the rotating shaft guiding platform 505. The convex end 506 is fixedly connected to the front side of the rotating shaft guiding platform 505. A groove 11 is formed at the rear side of the rotating shaft limiting fixture 9. The lower end of the rotating shaft limiting fixture 9 is arranged on the upper surface of the tapping table 10, and the lower end of the tapping table 10 is fixedly connected to the upper surface of the tapping frame 1. V-shaped card slots 507 are formed on the sides of the rotating shaft guiding platform 505 and the rotating shaft limiting fixture 9 close to each other. A motor rotating shaft 4 to be tapped is horizontally penetrated through the V-shaped card slot 507. A limiting electric push rod 8 is arranged on the front side of the rotating shaft limiting fixture 9. The free end of the limiting electric push rod 8 is in transmission connection with the rotating shaft limiting fixture 9, and the fixed end of the limiting electric push rod 8 is fixedly connected to the upper surface of the outer support leg 6. The lower end of the tapping frame 1 is fixedly connected to a fixed steel frame 2. The operator stacks the motor rotating shafts that need to be tapped later in the rotating shaft placement frame 502. The micro electric push rod 508 pushes the motor rotating shaft at the front side position in the rotating shaft placement frame 502. The micro electric push rod 508 pushes the motor rotating shaft upward so that its height is higher than that of the front baffle 504. Under the action of gravity, the rotating shaft slides downward along the inclined surface guiding plate 503. After the rotating shaft slides off the inclined surface guiding plate 503, it will enter the area of the rotating shaft placement frame 502 and continue to move forward until its shaft body is captured by the V-shaped card slots 507 on both sides. The convex end 506 on the rotating shaft guiding platform 505 helps to guide the rotating shaft to more accurately enter the V-shaped card slot 507 of the rotating shaft limiting fixture 9. When the motor rotating shaft is preliminarily positioned by the V-shaped card slot 507, the front limiting electric push rod 8 starts to act. The fixed end of the limiting electric push rod 8 is fixed on the outer support leg 6, and its free end pushes the rotating shaft limiting fixture 9 forward. The rotating shaft limiting fixture 9 moves forward, and the V-shaped card slot 507 on it cooperates more closely with the V-shaped card slot 507 of the rotating shaft guiding platform 505, so as to firmly clamp the motor rotating shaft between the two V-shaped card slots 507, ensuring that its position is stable and immovable during the tapping process. The feeding guiding mechanism 5 realizes partial automation of the rotating shaft from input to positioning and clamping, reduces manual handling and manual alignment operations, greatly reduces the labor intensity of the operator, and improves the automation level of the overall production line.

[0036] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the application shall be included within the protection scope of the present application.
