Description

Technical Field

[0001] The invention relates to the technical field of grounding ring processing, and in particular to a device for processing a high-conductivity fiber grounding ring for a new energy motor. Background Art

[0002] The high-conductivity fiber grounding ring for new energy motors (hereinafter referred to as grounding ring) is a key component used in new energy motors. It is made of high-conductivity fiber and can effectively conduct static electricity and leakage generated during motor operation to ensure safe and stable operation of the motor. There is actually a grounding ring structure such as Fig.10 As shown in the figure, the grounding ring is evenly provided with multiple radial holes in the circumference, and the grounding ring is provided with vertical mounting holes. The radial holes are used to stably and quickly connect the grounding ring and radial parts. The processing operation of the grounding ring covers multiple links, from raw material preparation, molding to surface treatment, and each step is crucial. Drilling is an indispensable link. Accurate drilling can better connect and fix the grounding ring with other components, ensuring that it can play a stable role in the motor.

[0003] In the actual processing, the operation of drilling holes in the grounding ring usually uses a special tooling fixture to fix the grounding ring. After the grounding ring is fixed, the position of the drilling equipment with strictly controlled parameters is continuously adjusted to ensure that the drilling equipment can drill radial holes that are uniform in the circumference of the grounding ring.

[0004] Although the above-mentioned drilling method and equipment can quickly drill radial holes on the grounding ring, there are still some problems in actual operation. First, the material used to make the grounding ring is not entirely metal, so the grounding ring itself is not very hard. At the same time, the grounding ring is a ring structure, which causes the thrust generated by the drilling equipment during feeding to easily deform the grounding ring, and the above-mentioned special tooling fixture cannot specifically offset the thrust generated during the drilling process according to different drilling positions; secondly, although the drilling equipment with strict parameter control can try its best to reduce the precision error of the drilling hole, it cannot guarantee that the size of the drilled radial hole fully meets the requirements. At the same time, after the drilling is completed, burrs will be generated in the radial hole of the grounding ring, which will affect the subsequent installation of the grounding ring and other parts.

[0015] The beneficial effects of the present invention are as follows: 1. The present invention adopts a transmission unit to drive the abutment element and the cleaning element to achieve the protection of the inner ring surface of the grounding ring and the cleaning of burrs on the inner wall of the borehole while performing hole diameter trimming, and the reset spring is used to connect the embedded rod and the matching rack to ensure that the arc-shaped abutment plate contacts the grounding ring before the drilling machine, thereby continuously protecting the inner ring surface of the grounding ring during the drilling process; in addition, the inner through rod is abutted against the inner ring surface of the grounding ring and is located between the drilled hole and the drilling machine, so that the weak part of the part is targetedly protected by the inner through rod and the inner spring, thereby avoiding the situation in which the drilling machine generates an inward thrust on the grounding ring during drilling, causing the grounding ring to deform.

[0016] 2. The present invention uses a cleaning element to clean burrs on the inner wall of the drilled hole, thereby ensuring that the inner wall of the drilled radial hole is smooth, thereby ensuring that the radial hole and the parts installed at the radial hole position are quickly and stably connected. At the same time, the cleaning element can also trim the aperture of the radial hole, thereby further ensuring the accuracy of the aperture through the trimming of the aperture, thereby facilitating the subsequent installation of the grounding ring and the parts installed at the radial hole position.

[0017] 3. The present invention can quickly rotate the center column and adjust the drilling position of the grounding ring by rotating the adjusting element, and at the same time can make the grounding ring remain stable before and after the rotation of the center column, thereby ensuring the stability of the grounding ring when the drilling machine drills the grounding ring; and before the drilling machine drills the radial hole in the grounding ring, the ball and the lower support plate will be inserted into the through groove set in the fixed plate, so that the drilling machine, the lower support plate and the fixed plate are integrated, thereby ensuring that the drilling machine drills the grounding ring stably; in addition, the cleaning element can trim the inner diameter of the drilled hole through the friction pad, the guide groove and the guide rod while the inner through rod passes through the drilled radial hole, thereby ensuring the drilling accuracy of the grounding ring by the drilling machine.

[0018] Fourth, during the drilling process, the present invention uses a fixed plate to cooperate with the transmission unit to move the arc-shaped support plate toward the grounding ring, thereby ensuring that the arc-shaped support plate contacts the grounding ring only when drilling the grounding ring, thereby preventing the arc-shaped support plate that protects the inner ring surface of the grounding ring from causing friction to the grounding ring when the grounding ring rotates, thereby preventing the dimensional accuracy of the inner ring surface of the grounding ring from being affected. After the positioning of the grounding ring is completed, the bottom of the grounding ring will contact the ball bearing provided on the top of the lower support plate. When the grounding ring is subsequently rotated and adjusted, the ball bearing can also ensure that the grounding ring is not subjected to large friction to affect the dimensional accuracy of the upper and lower sides of the grounding ring, thereby ensuring that the processed grounding ring and other parts are quickly and accurately installed.

[0031] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product specifications are used.

[0032] See also Figure 1-Figure 2 A new energy motor high-conductivity fiber grounding ring processing device includes a processing machine tool 1, a connecting frame 11 is symmetrically fixed in the processing machine tool 1, and the opposite sides of the two connecting frames 11 are installed with fixing plates 121 through cylinders 12, and the opposite sides of the two fixing plates 121 are installed with drilling machines 2. A clamping unit 3 is installed in the processing machine tool 1 and located at the symmetry axis position of the two connecting frames 11. A supporting unit 4 is connected in the processing machine tool 1 and between the clamping unit 3, and a transmission unit 5 is connected between the supporting unit 4 and each fixing plate 121.

[0033] The present invention positions and clamps the grounding ring by cooperating with the clamping unit 3 and the supporting unit 4, thereby ensuring that the grounding ring is in a stable state during the drilling process. At the same time, the supporting unit 4 can not only support the bottom of the grounding ring, but also continuously support and protect the inner ring surface of the grounding ring at the drilling position during the drilling process of the drilling machine 2, thereby avoiding the situation in which the grounding ring is deformed due to the large stress generated by the drilling machine 2 on the grounding ring during the drilling process.

[0034] Specifically, first, the grounding ring is placed horizontally on the support unit 4, and the support unit 4 pre-positions the position of the grounding ring. In the process of placing the grounding ring, it may be necessary to pass through the clamping unit 3. At this time, it is only necessary to pass the grounding ring through the clamping unit 3 in sequence, and then control the clamping unit 3 to clamp and position the grounding ring according to the vertical installation hole opened on the grounding ring. After the clamping and positioning is completed, first control the two cylinders 12 to synchronously push the fixing plate 121 and the drilling machine 2 to move toward the grounding ring. As the fixing plate 121 moves, the transmission unit 5 will simultaneously drive the support unit 4 to protect the inner ring surface of the drilling position of the grounding ring, thereby ensuring that the drilling machine 2 can stably drill radial holes in the grounding ring. After the first group of radial holes are drilled, the clamping unit 3 is controlled to drive the grounding ring to rotate and stabilize, and then the above drilling operation is repeated until all radial holes are evenly drilled on the grounding ring.

[0035] See also Figure 2-Figure 4 The clamping unit 3 includes a central column 31 rotatably installed in the processing machine tool 1, a rotation adjustment element 32 is connected between the central column 31 and the processing machine tool 1, an electric push rod 311 is installed on the top of the central column 31, and a connecting plate 312 is fixed to the pushing section of the electric push rod 311. The connecting plate 312 is symmetrically provided with limit slide grooves front and back, and a limit slider is slidably connected in each limit slide groove. A positioning rod 313 is fixed to the bottom of the limit slider, and a spacing adjustment element 33 is commonly connected between the two limit sliders and the connecting plate 312.

[0036] The spacing adjustment element 33 includes an adjustment screw 331 rotatably mounted on the top of the connecting plate 312 , a moving ring 332 is threadedly connected to the adjustment screw 331 , and a connecting rod 333 is hinged on the outer ring surface of the moving ring 332 and the top of each limiting slider.

[0037] The clamping unit 3 can position the grounding ring according to the pre-drilled installation holes of the grounding ring, thereby cooperating with the support unit 4 to ensure that the grounding ring is in a stable state. At the same time, the positions of the two positioning rods 313 can be quickly adjusted through the spacing adjustment element 33, so as to position and clamp the grounding ring according to the installation holes at different positions on the grounding ring.

[0038] Specifically, the operator first puts the front side of the grounding ring that needs to be drilled through the connecting plate 312, and then moves the grounding ring as a whole backward until the rear side of the grounding ring can quickly put through the connecting plate 312, and then places the completed grounding ring on the support unit 4, and ensures that the mounting hole position of the grounding ring is vertically distributed, and then rotates the adjusting stud 331 according to the mounting hole position of the grounding ring to ensure that the two positioning rods 313 can be quickly aligned with the mounting hole of the grounding ring. After the position adjustment of the two positioning rods 313 is completed, the electric push rod 311 is controlled to drive the connecting plate 312 and the two positioning rods 313 to move downward as a whole until the two positioning rods 313 are inserted into the mounting hole of the grounding ring, and the grounding ring is pressed against the support unit 4 to complete the positioning of the grounding ring.

[0039] See also Figure 3-Figure 5 The support unit 4 includes a U-shaped support frame 41 fixed in the processing machine tool 1, and the two vertical sections of the U-shaped support frame 41 are symmetrically distributed with the central column 31. The central column 31 is rotatably connected to the horizontal section of the U-shaped support frame 41. The top of the vertical section of the U-shaped support frame 41 is symmetrically provided with abutment elements 42, and each abutment element 42 is provided with a cleaning element 43.

[0040] The supporting element 42 includes a limiting sleeve 421 fixed on the top of the horizontal section of the U-shaped support frame 41, and the limiting sleeve 421 is symmetrically slidably connected to a round rod 422 at one end away from the center column 31, and a lower supporting plate 423 is fixed to one end of the two round rods 422 away from the limiting sleeve 421. The lower supporting plate 423 is connected to the transmission unit 5, and an arc-shaped supporting plate 424 is fixed on the top of the lower supporting plate 423. An avoidance groove is provided in the middle of the arc-shaped supporting plate 424 and corresponds to the position of the drilling machine 2; a plurality of evenly arranged balls 425 are provided on the top of the lower supporting plate 423 and between the drilling machine 2 and the arc-shaped supporting plate 424; a through groove is provided on the fixed plate 121 and corresponds to the position of the lower supporting plate 423 and the balls 425.

[0041] The support unit 4 is used to support the bottom of the grounding ring, and at the same time, the inner ring surface of the grounding ring drilling position is continuously abutted by the abutment element 42 during the drilling process, thereby avoiding the inward thrust generated during drilling and causing the grounding ring to deform. At the same time, in order to avoid the arc-shaped abutment plate 424 that protects the inner ring surface of the grounding ring causing friction to the grounding ring when the grounding ring rotates and affecting the dimensional accuracy of the grounding ring, the fixed plate 121 is used to cooperate with the transmission unit 5 during the drilling process to move the arc-shaped abutment plate 424 toward the grounding ring, thereby ensuring that the arc-shaped abutment plate 424 is in contact with the grounding ring only when drilling the grounding ring.

[0042] Specifically, when the grounding ring is positioned, the bottom of the grounding ring will contact the top of the ball 425 set on the top of the lower support plate 423. When the grounding ring rotates and adjusts its position later, the ball 425 will also ensure that the grounding ring is not subjected to large friction and affects the dimensional accuracy of the grounding ring. Then, the two cylinders 12 are synchronously controlled to push the fixed plate 121 and the drilling machine 2 toward the grounding ring. As the fixed plate 121 moves, the transmission unit 5 will drive the lower support plate 423 and the arc-shaped support plate 424 to move toward the inner ring surface of the grounding ring. When the drilling machine 2 approaches the grounding ring, the arc-shaped support plate 424 will first abut against the inner ring surface of the grounding ring, and then the drilling machine 2 will be controlled to drill radial holes in the grounding ring. At this time, the ball 425 and the lower support plate 423 will be inserted into the through groove set on the fixed plate 121, so that the drilling machine 2, the lower support plate 423 and the fixed plate 121 are integrated, thereby ensuring that the drilling machine 2 can drill the grounding ring stably.

[0043] See also Figure 5-Figure 6 The transmission unit 5 includes an L-shaped connecting rod 51 fixed to the bottom of the fixed plate 121, and the horizontal section of the L-shaped connecting rod 51 is fixed with an embedded rod 511, and the embedded rod 511 is sleeved with a matching rack 512, and a return spring is connected between the embedded rod 511 and the matching rack 512; a driving element 52 is commonly connected between the vertical section of the U-shaped support frame 41 and the transmission unit 5 at the corresponding position.

[0044] The driving element 52 includes a horizontal plate 521 fixed on the side of the vertical section of the U-shaped support frame 41, a central gear 522 is rotatably installed on the top of the horizontal plate 521, an L-shaped lower extension rod 523 is fixed to the rear side of the lower support plate 423, and an alignment rack 524 is fixed to the bottom of the vertical section of the L-shaped lower extension rod 523. The alignment rack 524 and the matching rack 512 are both engaged with the central gear 522; a matching block 525 is symmetrically fixed to the front side of the vertical section of the U-shaped support frame 41.

[0045] The transmission unit 5 synchronously drives the abutment element 42 and the cleaning element 43 to respectively protect the inner ring surface of the grounding ring and clean the inner wall of the drilled hole and trim the hole diameter. At the same time, a reset spring is used to connect the embedded rod 511 and the matching rack 512 to ensure that the arc-shaped abutment plate 424 contacts the grounding ring before the drilling machine 2, thereby ensuring that the inner ring surface of the grounding ring is always protected by the arc-shaped abutment plate 424 during the entire process of drilling the grounding ring by the drilling machine 2.

[0046] Specifically, when the two cylinders 12 are controlled to push the fixing plate 121 and the drilling machine 2 to move toward the grounding ring, the fixing plate 121 will synchronously drive the L-shaped connecting rod 51, the embedded rod 511 and the matching rack 512 to move toward the vertical section of the U-shaped support frame 41. Since the matching rack 512 and the center gear 522 are in meshing state, the center gear 522 will rotate with the movement of the matching rack 512, and the alignment rack 524 is in meshing state with the center gear 522, so that the alignment rack 524 will rotate with the center gear 522. , and moves due to the rotation, and the moving directions of the alignment rack 524 and the matching rack 512 are opposite. When the matching rack 512 moves toward the direction of the vertical section close to the U-shaped support frame 41, the alignment rack 524 will move toward the direction of the vertical section away from the U-shaped support frame 41, thereby driving the lower support plate 423 and the arc-shaped support plate 424 to move toward the direction of the vertical section away from the U-shaped support frame 41 (i.e., the inner ring surface of the grounding ring) through the L-shaped lower extension rod 523, so as to achieve the purpose of the arc-shaped support plate 424 moving with the movement of the drilling machine 2.

[0047] When the matching rack 512 moves to the right and contacts with the matching block 525, the embedded rod 511 and the L-shaped connecting rod 51 will still move with the fixing plate 121 and the drilling machine 2 in the direction of the vertical section of the U-shaped support frame 41, thereby driving the drilling machine 2 to drill the radial holes on the grounding ring. At this time, the arc-shaped abutment plate 424 has been against the inner ring surface of the grounding ring. As the drilling machine 2 drills the grounding ring, the embedded rod 511 will compress the reset spring. When the drilling machine 2 completes the drilling of the grounding ring, the embedded rod 511 will drive the matching rack 512 to return to its original position through the reset spring. During the process of the two returning to their original positions, the reset spring will be in a stretched state. However, during the subsequent drilling operation, the embedded rod 511 and the matching rack 512 will still repeat the above-mentioned actions, so that the arc-shaped abutment plate 424 can always contact the grounding ring before the drilling machine 2.

[0048] See also Figure 3 , Figure 4 , Figure 7 , Figure 8 and Fig. 9 The two cleaning elements 43 are symmetrically distributed with the central column 31 as the axis center. The cleaning element 43 includes an inclined slide rail 431 fixed on the limiting sleeve 421, and a push rod 432 is connected to the inclined slide rail 431 through an inclined slider. A square sleeve 433 is rotatably installed on the top of the push rod 432, and an internal through structure is arranged in the square sleeve 433; a square plate is fixed on the side of the arc-shaped abutment plate 424 close to the central column 31, and a push rod 434 located on the left and right sides of the push rod 432 is fixed to the square plate corresponding to the push rod 432.

[0049] The inner through structure includes a circular plate 435 slidably connected in the square sleeve 433, an inner spring is connected between the circular plate 435 and the square sleeve 433, an inner through rod 436 is rotatably installed on the side of the circular plate 435 close to the arc-shaped support plate 424, a receiving groove is provided on the arc-shaped support plate 424 and corresponds to the position of the inner through rod 436, a guide groove is provided in the square sleeve 433, and a guide rod 437 matching the guide groove is fixed on the side of the inner through rod 436, and the guide groove as a whole is composed of multiple sections of small bending grooves.

[0050] In this embodiment, if Figure 7 and Figure 8 As shown, the size of the accommodating groove is larger than the size of the inner through rod 436, and friction pads are staggeredly arranged on the side of the inner through rod 436.

[0051] The cleaning element 43 can not only clean the inner wall of the previously drilled hole in the grounding ring, but also drive the inner through rod 436 to trim the inner diameter ring of the drilled hole through the friction pad, guide groove and guide rod 437, thereby ensuring the dimensional accuracy of the drilled radial hole, and before the inner through rod 436 enters the drilled hole, the inner through rod 436 will first contact the inner ring surface of the grounding ring and be located between the drilled hole and the drilling machine 2, so that the weak part of this part is targetedly protected by the inner through rod 436 and the inner spring, thereby avoiding the grounding ring from being deformed due to the stress generated by drilling during the drilling process of the drilling machine 2.

[0052] Specifically, when the L-shaped lower extension rod 523 drives the lower support plate 423 and the arc-shaped support plate 424 to move in the direction away from the vertical section of the U-shaped support frame 41, the pushing rod 434 will synchronously drive the pushed rod 432 and the square sleeve 433 as the arc-shaped support plate 424 moves, so that the square sleeve 433 and the inner through rod 436 move in the direction close to the inner ring surface of the grounding ring until the inner through rod 436 contacts the inner ring surface of the grounding ring. At this time, due to the guiding effect of the accommodating groove on the inner through rod 436, the inner through rod 436 cannot be aligned with the radial hole drilled previously, so the inner The through rod 436 will be pressed by the inner surface of the grounding ring and move into the square sleeve 433 until the arc-shaped support plate 424 abuts against the inner surface of the grounding ring. At this time, the push rod 432 moves to the end of the inclined slide rail 431 away from the center column 31, and then the inner through rod 436 moves from the inner surface of the grounding ring to the outer surface along the direction of the previously drilled radial hole. When the inner through rod 436 moves in the radial hole, the inner through rod 436 will swing back and forth due to the guide rod 437 and the guide groove, thereby cooperating with the friction pad to improve the size trimming effect of the inner wall of the radial hole.

[0053] See also Figure 3 and Figure 4The rotating adjustment element 32 includes a rotating ring 321 fixed on the central column 31, and a plurality of tooth-shaped protrusions 322 are evenly fixed on the bottom of the rotating ring 321 in a circumferential direction; a connecting sleeve 323 is fixed in the processing machine tool 1 and corresponds to the position of the tooth-shaped protrusion 322, and a moving rod 324 is connected to the connecting sleeve 323 through a vertical spring (not shown in the figure), and a toothed block 325 matching the tooth-shaped protrusion 322 is fixed on the top of the moving rod 324; a vertical groove 326 is opened on the side of the connecting sleeve 323, and an extension rod 327 is fixed on the moving rod 324 and corresponds to the position of the vertical groove 326.

[0054] The rotating adjustment element 32 is used to quickly rotate the center column 31, thereby adjusting the rotation angle of the grounding ring, and then quickly adjusting the position of the grounding ring where the hole needs to be drilled, and making the center column 31 in a stable state before and after the rotation, thereby ensuring that the grounding ring is in a stable state during the process of the drilling machine 2 drilling the grounding ring, thereby ensuring the accuracy of drilling the grounding ring.

[0055] Specifically, when the drilling machine 2 completes drilling the holes on the grounding ring, the operator presses down the extension rod 327, and the extension rod 327 will drive the moving rod 324 and the toothed block 325 to move downward together until the toothed block 325 is disengaged from the toothed protrusion 322, and then the center column 31 and the grounding ring are quickly rotated until the toothed block 325 is stuck in the next toothed protrusion 322, so that the drilling position of the grounding ring can be adjusted, and then the above drilling operation is repeated until all radial holes on the grounding ring are drilled.

[0056] The working steps of the present invention are as follows: In the first step, the operator places the grounding ring that needs to be drilled with radial holes horizontally on the support unit 4, and uses the support unit 4 to pre-position it. During the placement process, the grounding ring needs to pass through the clamping unit 3 front and back in sequence to ensure that the grounding ring can be smoothly leaned against the support unit 4.

[0057] In the second step, after the grounding ring is placed, the clamping unit 3 is controlled to clamp and position the mounting hole of the grounding ring, and before positioning the grounding ring, the adjusting stud 331 is first rotated to align the positioning rod 313 with the mounting hole, and then the positioning rod 313 is inserted into the mounting hole on the grounding ring through the electric push rod 311 until the connecting plate 312 presses the grounding ring against the supporting unit 4 and completes the positioning.

[0058] In the third step, after the clamping unit 3 and the supporting unit 4 cooperate to complete the positioning of the grounding ring, the two cylinders 12 are synchronously controlled to push the fixing plate 121 and the drilling machine 2 toward the grounding ring. At this time, the transmission unit 5 will drive the supporting unit 4 to protect the inner ring surface of the grounding ring drilling position, ensuring that the drilling machine 2 can stably drill radial holes in the grounding ring.

[0059] In the fourth step, when the drilling machine 2 moves and drills the radial holes on the grounding ring, the L-shaped lower extension rod 523 will drive the lower support plate 423 and the arc-shaped support plate 424 to move in the direction away from the vertical section of the U-shaped support frame 41, and the push rod 434 will synchronously drive the pushed rod 432 and the square sleeve 433 as the arc-shaped support plate 424 moves, so that the square sleeve 433 and the inner through rod 436 move in the direction close to the inner ring surface of the grounding ring until the inner through rod 436 contacts the inner ring surface of the grounding ring, and the inner through rod 436 is grounded. The inner surface of the ring is pressed and moved into the square sleeve 433 until the arc-shaped support plate 424 is pressed against the inner surface of the grounding ring. At this time, the push rod 432 moves to the end of the inclined slide rail 431 away from the center column 31, and then the inner through rod 436 moves from the inner surface of the grounding ring to the outer surface along the direction of the previously drilled radial hole. When the inner through rod 436 moves in the radial hole, the inner through rod 436 will swing back and forth due to the guide rod 437 and the guide groove, thereby cooperating with the friction pad to improve the size trimming effect of the inner wall of the radial hole.

[0060] In the fifth step, after the drilling machine 2 completes a set of radial holes in the grounding ring, the operator presses down the extension rod 327 and rotates the center column 31 and the grounding ring to adjust the position of the grounding ring, and then repeats the drilling operation. Subsequently, all the above-mentioned drilling and rotation adjustment actions are repeated multiple times as a group until all the radial holes on the grounding ring are drilled.
