Description

Technical Field

[0001] This utility model relates to the field of motor shaft cutting technology, and in particular to a cutting device for motor shaft processing. Background Technology

[0002] Motor shaft cutting is a crucial step in motor manufacturing and repair. Its purpose is to process the motor shaft to the required length or shape. Therefore, CN218745209U discloses a cutting device for processing motor main shafts. In use, the motor main shaft is placed on a rubber pad fixedly connected above a support block. The pressure block moves vertically as the first hydraulic telescopic rod extends, ultimately squeezing the motor main shaft. Meanwhile, the first rotating shaft rotates, driving the chain to rotate, causing the main shaft and driven shaft to begin rotating. The support block slides backward on the protrusion, allowing the front pressure block and support block to clamp the motor shaft. The main shaft of the machine is no longer clamped by the rear pressure block and support block. This allows the main shaft to move backward along with the clamping action of the pressure block and support block as the front support block rotates with the main shaft and driven shaft. This ensures that the shaft of the main shaft is positioned below the saw blade to receive cutting. The second motor drives the second rotating shaft to rotate, which in turn drives the saw blade to rotate. At this time, the second hydraulic telescopic rod can be retracted, allowing the saw blade, which is currently higher than the motor rotating shaft, to gradually approach the motor rotating shaft until the saw blade begins to cut the main shaft. As the second hydraulic telescopic rod retracts, the saw blade moves downward in the vertical direction, assisting in completing the saw blade's cutting function.

[0003] However, during the process of fixing the motor spindle, the spindle and driven shaft are located on both sides of the clamped motor spindle and are set close to the central shaft of the motor. Therefore, when the saw blade descends to cut the motor spindle, in order to prevent the saw blade from contacting the spindle and driven shaft, after the saw blade cuts one side of the motor spindle, it is necessary to rotate the clamped motor spindle to cut the other side. However, constantly adjusting the position of the rotating motor spindle will increase the difficulty of operation. Utility Model Content

[0004] The purpose of this invention is to solve the problem of motor shaft cutting in the prior art, and to propose a cutting device for motor shaft processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cutting device for machining motor shafts, comprising a cutting table and a saw blade mounting bracket installed on one side of the cutting table surface. Two symmetrically distributed rotating bars hinged to the cutting table surface are arranged in the middle of the cutting table surface. The space between the two rotating bars is used to place the motor spindle, and the saw blade mounting bracket is located at one end of the same side of the two rotating bars. A plurality of gears are rotatably connected to the upper surface of each rotating bar. The plurality of gears on the rotating bar are equidistantly distributed from near to far from the saw blade mounting bracket. A bracket is inserted into the upper surface of the gear. The upper part of the bracket is U-shaped and the upper part of the bracket is rotatably connected to an anti-slip wheel for supporting the motor spindle.

[0006] Preferably, a rack is inserted into the upper surface of the rotating bar, the rack meshes with several gears on the same rotating bar, and an electric push rod is connected between the rack and the upper surface of the rotating bar.

[0007] Preferably, a connecting frame is fixedly installed on the surface of the insert, facing the upper surface of the rotating bar, and the bottom edge of the connecting frame is sleeved on the top of the gear, and a rotating ring coaxially arranged with the gear is rotatably connected to the bottom edge of the connecting frame.

[0008] Preferably, the rotating ring is arranged in a ring shape in the middle and has two horizontal extensions on the outer side of the rotating ring. One horizontal extension of the rotating ring is sleeved on the rotating bar, and the other horizontal extension of the rotating ring faces the rack and is arranged in a column shape.

[0009] Preferably, an insert is inserted into the upper surface of the rack, and a slanted frame is fixedly installed on the upper surface of the insert near any rotating ring at another horizontal extension of the rotating ring.

[0010] Preferably, the upper surface of the cutting table is equipped with several mounting rails on both sides of the two rotating bars.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figure 1-5As shown, a cutting device for machining motor shafts includes a cutting table 1 and a saw blade mounting bracket 2 installed on one side of the cutting table 1. The specific structure of the saw blade mounting bracket 2 is similar to the "fixed column" mechanism in a cutting device for machining motor spindles disclosed in CN218745209U, and is used to install a "second hydraulic telescopic rod and saw blade" to achieve cutting of the passing motor spindle. Two symmetrically distributed rotating bars 8 are provided in the middle of the cutting table 1 and hinged to the cutting table 1. The space between the two rotating bars 8 is used to place the motor spindle, and the saw blade mounting bracket 2 is located at one end of the same side of the two rotating bars 8. Several gears 11 are rotatably connected to the upper surface of each rotating bar 8. The gears 11 on the rotating bar 8 are distributed at equal intervals from near to far from the saw blade mounting bracket 2. A bracket 14 is inserted into the upper surface of the gear 11. The upper part of the bracket 14 is U-shaped and the upper part of the bracket 14 is rotatably connected to an anti-slip wheel 7 for supporting the motor spindle. A rack 10 is inserted into the upper surface of the rotating bar 8. The rack 10 is connected to the same... Several gears 11 on the rotating bar 8 are meshed together. An electric push rod 9 is connected between the rack 10 and the upper surface of the rotating bar 8. In actual use, the motor spindle is placed between the two rotating bars 8 and the motor spindle is in contact with the surfaces of several anti-slip wheels 7 on the two rotating bars 8. In actual use, the electric push rod 9 extends and retracts to move the rack 10, and under the action of meshing, the gears 11 meshing with the rack 10 rotate. By driving the gears 11 to rotate, the bracket 14 rotates, which in turn makes the anti-slip wheels 7 rotate. When the central axis of the anti-slip wheel 7 is set perpendicular to the central axis of the motor spindle, the rotation of the anti-slip wheel 7 can drive the motor spindle to move relative to the saw blade mounting bracket 2, which can realize automatic feeding of the motor spindle. When the central axis of the anti-slip wheel 7 is set parallel to the central axis of the motor spindle, the rotation of the anti-slip wheel 7 can drive the motor spindle to rotate, which can realize that after the saw blade cuts a part of the motor spindle, the rotation of the motor spindle makes it convenient for the saw blade to cut other parts of the motor spindle, thus adjusting the cutting part of the motor spindle.

[0024] In addition, the rotating bar 8 in this solution is driven to rotate and swing by installing a servo motor on the table surface of the cutting table 1, or by installing a servo motor on one or more of the brackets 14 to drive the anti-slip wheel 7 at the corresponding position to rotate.

[0025] To adjust the height of the anti-slip wheel 7: A connecting bracket 17 is fixedly installed on the surface of the insert 14, facing the upper surface of the rotating bar 8. The bottom edge of the connecting bracket 17 is fitted onto the top of the gear 11, and a rotating ring 15 coaxially connected to the bottom edge of the connecting bracket 17 is rotatably connected to the gear 11. When the rotating ring 15 cannot rotate, and the insert 14 drives the anti-slip wheel 7 to rotate, the corresponding connecting bracket 17 connected to the insert 14 will rotate synchronously, and the connecting bracket 17 will rotate relative to the rotating ring 15. To ensure that the rotating ring 15 does not rotate, the middle of the rotating ring 15 is annular, and two horizontal extensions are provided on the outer side of the rotating ring 15. One horizontal extension of the rotating ring 15 is fitted onto the rotating bar 8, and the other horizontal extension of the rotating ring 15 faces the rack 10 and is columnar. Figure 3 The rotating bar 8 has a columnar protrusion that extends horizontally through the side of the rotating ring 15; a strip 12 is inserted into the upper surface of the rack 10, and a slanted frame 13 is fixedly installed on the upper surface of the strip 12 near any rotating ring 15 at another horizontal extension of the rotating ring 15. The surface of the strip 12 extends outward and is also connected to the rotating bar 8 through an electric push rod 9. Therefore, under the connection of the electric push rod 9, when the electric push rod 9 is not extended or retracted, the strip 12 will not move when the rack 10 moves. The rack 10 moves relative to the insert 12 and the rotating bar 8. When the insert 12 moves, the inclined frame 13 connected to the insert 12 moves synchronously. Therefore, when the inclined frame 13 moves forward, the other horizontal extension of the rotating ring 15 connected to the inclined frame 13 will gradually rise, thereby driving the rotating ring 15 and the connecting frame 17 to rise synchronously. This allows the insert frame 14 to drive the anti-slip wheel 7 to rise and adjust the height of the anti-slip wheel 7. Furthermore, by using the rotating bar 8 to rotate and swing, it can be ensured that the anti-slip wheel 7 abuts against the surface of the motor spindle of different diameters.

[0026] To prevent the motor spindle from shaking when the anti-slip roller 7 rotates and to prevent the motor spindle from shaking during the cutting process: several mounting rails 3 are installed on the upper surface of the cutting table 1 on the opposing sides of the two rotating bars 8. A slider 4 is inserted into the mounting rail 3. A horizontally set hydraulic rod 5 is fixedly installed on the top edge of the slider 4. The telescopic end of the hydraulic rod 5 faces the middle of the cutting table 1 and is fixedly installed with a frame 16. A clamping rod 6 for pressing the motor spindle is inserted into the frame 16. The side of the mounting rail 3 is hollowed out, and the hollow part of the side of the mounting rail 3 is connected to the slider 4 by a pin. By using pins to connect the cutouts on the mounting rail 3 and the slider 4 at different positions, the installation position of the slider 4 can be adjusted. This allows for easy adjustment of the initial position of the clamping rod 6 according to the diameter of the motor spindle being supported. The clamping rod 6 can be moved toward and clamped to the motor spindle by extending the hydraulic rod 5. In addition, the clamping rod 6 is L-shaped and is also connected to the insert frame 16 by pins. Therefore, it is convenient to select and replace clamping rods 6 of different sizes according to the size of the motor spindle, ensuring that the top and sides of the clamping rod 6 are in contact with the surface of the motor spindle and preventing the motor spindle from shaking up and down.

[0027] The working principle is as follows: the motor spindle is placed between two rotating bars 8, and the motor spindle contacts the anti-slip wheel 7 on the rotating bars 8. The hydraulic rod 5 extends, which moves the clamping rod 6 towards the motor spindle and clamps the motor spindle. When the motor spindle needs to move towards the saw blade mounting bracket 2, the drive gear 11 rotates, which causes the bracket 14 to rotate, thus rotating the anti-slip wheel 7. When the central axis of the anti-slip wheel 7 is perpendicular to the central axis of the motor spindle, the rotation of the anti-slip wheel 7 can drive the motor spindle to move relative to the saw blade mounting bracket 2. After the movement is completed, the drive gear 11 rotates again. When the central axis of the anti-slip wheel 7 is parallel to the central axis of the motor spindle, the rotation of the anti-slip wheel 7 can drive the motor spindle to rotate. This allows the saw blade to cut a part of the motor spindle, and the rotation of the motor spindle facilitates the saw blade to cut other parts of the motor spindle, thus adjusting the cutting position of the motor spindle.

[0028] The wiring diagrams for the hydraulic rod 5, electric push rod 9, and servo motor in this utility model are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts of the hydraulic rod 5, electric push rod 9, and servo motor will not be explained in detail.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
