Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rotor processing device, in particular to a motor rotor processing technology and processing device. BACKGROUND

[0002] In the process of processing the automobile motor rotor, the shell surface of the automobile motor rotor needs to be processed using a drill bit. However, during the processing using the drill bit, iron filings often splash. In the process of continuous production, continuous processing produces iron filings, which can accumulate and splash, causing the processing table to be contaminated and affecting the remaining processing. In the existing rotor processing process, the iron filings are generally adsorbed by a negative pressure suction cylinder, which adsorbs the splashed iron filings to a centralized position for centralized treatment. In addition, the automobile motor rotor is large in size, and the processing surface needs to be processed for a long time, resulting in a large amount of iron filings and frequent replacement of the drill bit. If the iron filings are not properly treated during processing, the drill bit can be clogged, and the processing surface can also be abnormal.

[0003] However, in the prior art, when the negative pressure suction cylinder is used to suck the splashed iron filings, the drill bit is inserted into the suction cylinder, and the negative pressure suction cylinder is coaxial with the drill bit. This can cause the drill bit to come into contact with the rotor shaft when it is close to the processing surface of the rotor, and the rotor shaft can collide with the negative pressure suction cylinder. In addition, if the processing drill bit has a high speed, the splashed debris can also be fast. If the negative pressure suction cylinder cannot be close in physical distance, the negative pressure suction force cannot suck the debris into the negative pressure suction cylinder in time. Therefore, a motor rotor processing technology and processing device are proposed. SUMMARY

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1, such as Figure 1 As shown, a motor rotor machining process includes the following steps: S1. After the initial machining of the motor rotor is completed, the motor rotor is installed on the rotating base and fixed by the rotating base. The machining drill bit is then passed through the machining hole of the machining device. S2. After the drill bit is positioned in the processing hole of the adsorption device, fix the position of the drill bit and the motor rotor, and synchronously adjust the adsorption device and the drill bit to the processing end face of the motor rotor. S3. Surround the central axis of the motor rotor with the external shielding of the adsorption device to shield the machined surface of the motor rotor and the central axis. S4. After the shielding is completed, the machining drill bit is started to contact the machining end face of the motor rotor. When iron filings are generated and splashed, the adsorption device is started to simultaneously adsorb the splashed iron filings into the collection device.

[0022] This application discloses a motor rotor processing technology and processing device. The processing device in S1 includes a front and rear moving plate 102. A suction cylinder 104 is installed on the outside of the front and rear moving plate 102 by screws. A moving structure is installed on the outside of the front and rear moving plate 102. The side of the suction cylinder 104 near the rotor is a blade-shaped inclined surface. Multiple suction holes 105 are opened on the blade-shaped inclined surface of the suction cylinder 104. A suction connecting cylinder 106 is connected to one side of the suction cylinder 104. The suction connecting cylinder 106 is the same as an external suction pump. The outer part of the suction cylinder 104 is fixedly connected with an elastic soft plate 107, the side of the suction cylinder 104 away from the elastic soft plate 107 is fixedly connected with a clamping ring 111, the side of the elastic soft plate 107 away from the suction cylinder 104 is inserted into the inner part of the clamping ring 111 and surrounds the rotor to form a shielding cover, and the outer part of the elastic soft plate 107 is installed with a blowing structure.

[0023] Specifically, in use, the staff can install the suction cylinder 104 to the outer part of the front and rear moving plate 102 through screws, and move the suction cylinder 104 to the position of the drill bit through the moving structure, and insert the drill bit into the inner part of the suction cylinder 104 through the outer opening. During the machining process, when the drill bit contacts the machining surface of the rotor and passes through the suction cylinder 104, the external suction pump connected with the air suction connecting cylinder 106 is started, and the external suction pump cooperates with the air suction connecting cylinder 106 and the suction hole 105 to generate a continuous suction force. During the process of machining the machining surface of the rotor by the drill bit, the generated iron filings are sucked into the inner part of the suction cylinder 104 through the suction force generated by the suction hole 105 and are transported to the inner part of the air suction connecting cylinder 106 through the suction cylinder 104, so that the adsorption and collection of the iron filings are completed.

[0024] Further, the side of the suction cylinder 104 close to the machining surface of the rotor is a blade-shaped inclined surface, which can reduce the volume of the side of the suction cylinder 104 close to the rotor, reduce the phenomenon of contact and collision between the whole suction cylinder 104 and the rotor shaft, and the setting of the inclined surface can generate a certain foothold when the iron filings fall on the inclined surface during the adsorption process. After the generation of the foothold, the iron filings falling on the inclined surface can be gradually sucked into the inner part of the suction cylinder 104 again by the adsorption of the suction force, so as to avoid that the traditional cylindrical suction has less foothold of the iron filings and the whole iron filings will roll to other positions through the cylindrical outer part.

[0025] Further, in order to avoid that some iron filings may be out of the suction range of the whole suction cylinder 104 under the condition of strong inertial force, so that the generated suction force cannot adsorb the iron filings, thereby causing part of the iron filings to still fall on the machining table, in order to avoid such a situation, the tail end of the elastic soft plate 107 is inserted into the inner part of the clamping ring 111, so as to curl the elastic soft plate 107 into a whole circular shielding cover. In the case of forming the circular shielding cover, even the iron filings splashing outward will be shielded by the circular shielding cover formed by the elastic soft plate 107, so as to reduce the situation that the iron filings continuously fall on the machining table.

[0026] As shown in Figure 1 and Figure 5 , one side of the elastic soft plate 107 is bonded with an electrostatic sticker 501, and the side of the electrostatic sticker 501 away from the elastic soft plate 107 is bonded with a shielding soft cloth 500.

[0027] Specifically, the static sticker 501 can be used to bond the shielding soft cloth 500 to one side of the air bag 108, so as to prevent the flying iron filings from falling onto the workbench through the side of the elastic soft plate 107, and considering that one side of the suction cylinder 104 is the rotor processing side and the other side is the drill moving surface, holes can be provided on the outside of the shielding soft cloth 500 for the drill to pass through.

[0028] As shown in Figure 1 , the blowing structure includes an air bag 108 integrally formed on the outside of the elastic soft plate 107, the outside of the air bag 108 is communicated with a gas delivery pipe 109, one end of the gas delivery pipe 109 away from the air bag 108 is connected with a gas pump, and a plurality of air supply pipes 110 are fixedly connected to the outside of the elastic soft plate 107, and the air inlets of the air supply pipes 110 are communicated with the air bag 108.

[0029] Specifically, considering that during use, although the debris can be shielded by the elastic soft plate 107, the shielded debris will still fall inside the elastic soft plate 107, and when the elastic soft plate 107 moves away from the rotor, the debris accumulated inside the elastic soft plate 107 may still fall onto the processing table, causing contamination of the processing table. Therefore, the gas delivery pipe 109 is used in cooperation with the external gas pump to continuously inject gas into the inside of the air bag 108, so that the air bag 108 stores gas, and when the air bag 108 is filled with gas, the gas will be delivered to the inside of the shielding cover formed by the elastic soft plate 107 through the plurality of air supply pipes 110 communicated with the air bag 108, forming a blowing effect on the debris inside the shielding cover. When the plurality of air supply pipes 110 deliver gas into the inside of the shielding cover, the debris inside the shielding cover will be blown up, and the blown-up debris will be sucked into the inside of the suction cylinder 104 by the suction force in the suction hole 105, thereby reducing the accumulation of debris inside the elastic soft plate 107 and further preventing the debris from falling onto the processing table.

[0030] As shown in Figures 1-7 , the bottom of the clamping ring 111 is provided with a sliding groove, and the clamping plate 600 is clamped in the sliding groove in interference.

[0031] Specifically, during use, after the elastic soft plate 107 is clamped into the inside of the clamping ring 111, the clamping plate 600 can be continuously pushed upwards, and the clamping plate 600 can continuously press the elastic soft plate 107 when the clamping plate 600 is pushed upwards, so as to clamp and fix the elastic soft plate 107 inside the clamping ring 111.

[0032] Further, the suction force generated by the suction pump through the suction hole 105 is greater than the gas blowing force generated by the air supply pipe 110.

[0033] As shown in Figures 1-2As shown, the moving structure comprises a mounting plate 100, a front and rear moving cylinder 101 is mounted on the mounting plate 100, the output shaft end of the front and rear moving cylinder 101 is connected with a mounting seat, the outside of the mounting seat is fixedly connected with the outside of a front and rear moving plate 102 through screws, a positioning cylinder 103 is fixedly connected on the mounting seat, two guide rods 801 are fixedly connected on the mounting plate 100, the outside of the guide rod 801 is fixedly connected with a fixed seat 800, a sliding hole is formed in the outside of the front and rear moving plate 102, and the fixed seat 800 is inserted into the sliding hole.

[0034] Specifically, in use, the whole application is mounted on the machining table through the mounting plate 100, and the front and rear moving plate 102 and the suction cylinder 104 are driven to move forward and backward by starting the front and rear moving cylinder 101, when the suction cylinder 104 is driven to move to a specified position, the output shaft of the positioning cylinder 103 penetrates the outer wall of the front and rear moving plate 102 and is inserted into the outer wall surface of the mounting plate 100, so as to position the whole position of the front and rear moving plate 102, and in the process of moving the front and rear moving plate 102 forward and backward, the fixed seat 800 is inserted into the sliding hole, so as to guide the front and rear moving plate 102 through the fixed seat 800, and the fixed seat 800 is supported through the guide rod 801.

[0035] Further, why the semi-soft elastic soft plate 107 is used to form the shielding cover is that the elastic soft plate 107 is light in weight, and can form a shielding space of any size in cooperation with the clamping ring 111 in the curled state, and the shielding cover also wraps the rotating shaft of the rotor, and the shielding space of any size can adapt to the positions of different rotating shafts, and the rotating shaft of the rotor is also shielded and wrapped, and the machining process of different rotors is adapted.

[0036] The technical scheme in the embodiment of the application has at least the following technical effects or advantages: compared with the prior art, in the embodiment, the suction cylinder 104 with the blade-shaped inclined surface can reduce the volume of the suction cylinder 104, and reduce the contact phenomenon between the suction cylinder 104 and the rotating shaft of the rotor in the machining process, so that the activity range of the suction cylinder 104 cooperating with the drill bit is larger, the moving range of the drill bit is larger, the machining range of the rotor is larger, and in the machining process, the shielding cover can also be formed by bending the elastic soft plate 107, the splashed debris is shielded, and the debris can also be blown up by blowing gas, and the blocked debris is blown and sucked into the inside of the suction connecting cylinder 106 by the suction force generated by the suction hole 105, so as to reduce the phenomenon that the debris falls on the table.

[0037] Embodiment two, considering that in the process of gas blowing, the blowing direction of the air supply pipe 110 changes with the bending of the elastic soft plate 107, and the overall blowing direction changes more when the elastic soft plate 107 is enclosed into a shielding cover, and a large difference in blowing direction may cause the gas to be unable to accurately blow the debris into the suction cylinder 104, in view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically: As shown in Figures 2-3 , a plurality of central soft bags 200 are integrally formed in the inside of the elastic soft plate 107, the inside of the central soft bag 200 is filled with electrorheological fluid, the central soft bag 200 surrounds the air supply pipe 110, the outside of the air supply pipe 110 is fixedly connected with an adjusting plate 201, and the adjusting plate 201 penetrates the outer wall of the air bag 108.

[0038] Specifically, a plurality of air supply pipes 110 are arranged transversely in the elastic soft plate 107, and each row of air supply pipes 110 has an adjusting plate 201 outside. The angle of the entire row of air supply pipes 110 can be adjusted by the adjusting plate 201 on the current row of air supply pipes 110. During use, the worker can adjust the orientation angle of the current row of air supply pipes 110 by holding the adjusting plate 201. The air supply pipe 110 is connected in the elastic soft plate 107 by the central soft bag 200. The soft material of the central soft bag 200 can conveniently adjust the direction of the adjusting plate 201 by the worker, and the direction of the air supply pipe 110 is adjusted by the adjusting plate 201. After the direction adjustment is completed, the electrorheological fluid in the central soft bag 200 is energized by the wire. The electrorheological fluid will harden after being energized. The hardened electrorheological fluid can fix the air supply pipe 110, so as to limit and fix the blowing direction of the air supply pipe 110 as a whole.

[0039] As shown in Figures 1-9 , a plurality of air supply pipes 110 are arranged transversely on the outside of the elastic soft plate 107, and an infrared laser emitter 700 is installed at the center position of each row of air supply pipes 110. A plurality of infrared laser receivers 701 are installed on the inclined surface of the suction cylinder 104 in a knife blade shape. The plurality of infrared laser receivers 701 are arranged continuously. The infrared rays generated by the plurality of infrared laser emitters 700 have different intensities. When the continuously arranged infrared laser receivers 701 detect infrared rays of different intensities, it is determined that the intensity of the electrorheological fluid in the central soft bag 200 changes. That is, when it is determined that the intensity of the electrorheological fluid changes, the current in the central soft bag 200 is increased. The calculation formula of the current adjustment is: ; is the adjusted current value; is a constant, representing the initial current or reference current; is a proportional coefficient, representing the misalignment coefficient value of the infrared laser emitter 700; represents the misalignment degree, represents the position of the target infrared laser receiver 701 that the laser beam of the infrared laser emitter 700 accurately irradiates to when working normally, i.e., without misalignment, represents the position of the infrared laser receiver 701 that actually detects the laser signal at present, and the absolute value of the difference between the two , the physical meaning of which is that the absolute distance of the laser spot from the reference position on the receiver array, which directly reflects the misalignment degree of the air supply pipe 110.

[0040] Specifically, during use, the blowing direction of each row of air supply pipes 110 is controlled by the adjusting plate 201, but the final blowing direction is towards the suction hole 105 on the surface of the suction cylinder 104. If the orientation of the air supply pipe 110 deviates too much, it may cause the blowing gas to be disordered, causing the gas to blow out the debris inside the shielding cover, resulting in the debris falling on the machining table. By providing the center soft bag 200, when the adjusting plate 201 adjusts the orientation of the air supply pipe 110, the laser emitted by the center soft bag 200 can follow the orientation of the entire row of air supply pipes 110. By emitting laser to visualize the gas blowing direction of the air supply pipe 110, the staff can adjust the gas blowing direction of the air supply pipe 110 according to the laser emitted by the center soft bag 200.

[0041] Further, because the direction of the gas blowing is ultimately towards the suction hole 105 on the surface of the suction cylinder 104, and during long-term use, it is impossible for the staff to constantly watch the orientation of each laser, and once the orientation of the laser deviates slightly, the staff's eyes may not be able to observe it in time. By providing multiple infrared laser receivers 701, the laser generated by the infrared laser emitter 700 can be received, and the laser beams of multiple infrared laser emitters 700 can be received by multiple infrared laser receivers 701, so that the blowing direction of multiple air supply pipes 110 can be positioned, so that the blowing direction of the air supply pipe 110 is always towards the position of the suction cylinder 104 and the suction hole 105.

[0042] Further, if the signal reception between the infrared laser transmitter 700 and the infrared laser receiver 701 is lost, an external alarm is sounded in time, and when all the infrared laser transmitters 700 and the infrared laser receivers 701 outside the elastic soft plate 107 are lost, an alarm is sounded in time, and a single loss is prewarned, and the different light intensities of the infrared laser transmitters 700 received by the infrared laser receiver 701 determine the offset of the air supply pipe 110, wherein the calculation formula of the physical deflection angle of the air supply pipe 110 is: ; is the actual angle offset of the first air supply pipe 110; is the arctangent function; represents the horizontal offset distance of the laser spot on the receiver array; represents the fixed vertical distance from the installation position of the infrared laser transmitter 700 to the inclined surface of the suction cylinder 104 where the infrared laser receiver 701 array is located.

[0043] The technical solutions in the embodiments of the present application have at least the following technical effects or advantages: compared with the first embodiment, in the present embodiment, the soft material of the center soft bag 200 facilitates the adjustment of the angle of the air supply pipe 110 by the staff through the adjustment plate 201, and after the adjustment is completed, the current variable liquid inside the center soft bag 200 can be energized to make the current variable liquid solidify, and the solidified current variable liquid can fix the air supply pipe 110, so that the gas conveying direction of the air supply pipe 110 is always directed to the suction hole 105, and the gas conveying direction of the air supply pipe 110 can be adjusted arbitrarily according to the different sizes of the shielding cover formed by different infrared laser transmitters 700, increasing the flexibility of rotor processing.

[0044] Embodiment three, considering that during continuous blowing of gas, gas with different blowing directions is directly blown onto the elastic soft plate 107, and the elastic soft plate 107 is made of a deformable material, which may cause the elastic soft plate 107 to continuously shake under the continuous blowing of gas, thereby causing the gas blowing direction to change again, to solve the above technical problems, the present application proposes the following technical solutions, specifically: As shown in Figures 3-4 , the center soft bag 200 is integrally formed with a side strip-shaped fixed bag body 300 outside, the inside of the side strip-shaped fixed bag body 300 is filled with current variable liquid, and the number of the side strip-shaped fixed bag body 300 is not less than 2.

[0045] ​Specifically, in the use process, when the angle of the air supply pipe 110 is adjusted by the electrorheological fluid in the center soft bag 200, the staff can pass electricity to the electrorheological fluid in the side strip-shaped fixed bag body 300 through the wire and external power supply. When the electrorheological fluid in the side strip-shaped fixed bag body 300 is electrified, the side strip-shaped fixed bag body 300 can support the entire elastic soft plate 107. The number of side strip-shaped fixed bag bodies 300 is not less than 2, and the side strip-shaped fixed bag bodies 300 are arranged on the surface or both sides of the elastic soft plate 107. When the number of side strip-shaped fixed bag bodies 300 is two, the two side strip-shaped fixed bag bodies 300 are distributed on both sides of the elastic soft plate 107, and after the electrorheological fluid in the side strip-shaped fixed bag body 300 solidifies, it can form a frame support on both sides of the elastic soft plate 107, avoiding the shaking of the entire elastic soft plate 107 when the gas is blown into the elastic soft plate 107.

[0046] As shown in Figure 4 The center soft bag 200 and the side strip-shaped fixed bag body 300 are connected with a plurality of electromagnetic coils 400. The electrorheological fluid in the center soft bag 200 and the side strip-shaped fixed bag body 300 is connected with the electromagnetic coil 400 through the wire and the external power supply.

[0047] Specifically, considering the use for a long time, the electrorheological fluid in the center soft bag 200 and the side strip-shaped fixed bag body 300 will produce precipitation phenomenon under long-term use. Once the precipitation phenomenon occurs, the solidification effect of the electrorheological fluid may be weakened. Once the solidification effect is weakened, the direction of the air output of the air supply pipe 110 may be changed, resulting in incorrect blowing direction of the gas, causing debris to fall on the workbench. By arranging a plurality of electromagnetic coils 400, the electromagnetic coils 400 can be periodically electrified. The electromagnetic coils 400 generate a magnetic field, which attracts the precipitated particles in the electrorheological fluid and disperses the precipitation phenomenon in the electrorheological fluid.

[0048] Further, when the infrared laser emitter 700 and the infrared laser receiver 701 are misaligned, the electromagnetic coils 400 are electrified by the main controller, so that the electrorheological fluid in the center soft bag 200 is adjusted to prevent misalignment caused by the fixation failure of the air supply pipe 110 due to the precipitation phenomenon.

[0049] The technical solutions in the embodiments of the present application have at least the following technical effects or advantages: compared with the first embodiment, in the present embodiment, not only can the elastic soft plate 107 as a whole be fixed by the two side edge strip-shaped fixed sac bodies 300 cooperating with the electrorheological fluid solidification, to avoid the overall elastic soft plate 107 from shaking due to the airflow blown by the air supply pipe 110, but also when dislocation occurs between the infrared laser emitter 700 and the infrared laser receiver 701 after long-term use, the change in the wind direction of the air supply pipe 110 can be detected, so that the electromagnetic coil 400 is energized, and the particles inside the electrorheological fluid can be attracted in the case of energizing the electromagnetic coil 400, thereby reducing the precipitation phenomenon of the electrorheological fluid, and avoiding the phenomenon that the electrorheological fluid precipitates to cause the air supply pipe 110 and the elastic soft plate 107 to be unable to be fixed.

[0050] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. The present application can be variously changed and modified by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
