DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0023] The specific implementation of the present application is described in detail below in combination with specific examples.

[0024] Referring to Figures 1-7 , a motor spiral armature lamination press-fitting device based on a servo press comprises: a press-fitting machine 1; a press-fitting unit 2 rotationally connected in the press-fitting machine 1, the press-fitting unit 2 comprising a press head part 28 arranged along a press-fitting direction, the press head part 28 being used to directly abut against and apply pressure to the armature lamination to realize axial press-fitting of the armature lamination; a glue applying unit 3 connected to the press-fitting unit 2 along the press-fitting direction, an output end of the glue applying unit 3 penetrating through the press head part 28, used to move synchronously with the press-fitting action of the press head part 28, and cooperate with the press-fitting unit 2 to complete automatic glue applying between the armature lamination layers; The adjusting unit 4 is rotationally connected to the surface of the gluing unit 3, and is used for adjusting the pressing stroke of the pressing unit 2 and the pressure value of the pressure head 28 acting on the armature sheet through rotation of the adjusting unit 4.

[0025] In one embodiment of the present application, as shown in Figure 1 and Figure 2 The pressing unit 2 comprises: The support base 21 is rotationally connected to the pressing machine 1; The rotating table 22 is connected to the upper side of the support base 21, and four groups of positioning cores 23 are rotationally arranged on the upper surface of the rotating table 22, and the bottom of each positioning core 23 is connected with a support ring 24; The first motor 25 is installed in the pressing machine 1, and the output end of the first motor 25 is connected to the end of the support base 21; The second motor 26 is installed on the side of the rotating table 22, and the end of the positioning core 23 is connected to the output end of the second motor 26; the lead screw 27 is rotationally connected to the pressing machine 1, and the gluing unit 3 is threadedly connected to the surface of the lead screw 27, and the lower side of the gluing unit 3 is connected with the pressure head 28; The third motor 29 is installed on the upper side of the pressing machine 1, and the upper end of the lead screw 27 is connected to the output end of the third motor 29.

[0026] By adopting the above technical scheme, when the armature sheet is pressed, the armature sheet is guided into the positioning core 23 close to the feeding station through the feeding unit 5, and the support ring 24 arranged at the bottom of the positioning core 23 can stably support the armature sheet, effectively reducing the difficulty of taking out the armature sheet after pressing, and improving the convenience of discharging.

[0027] The first motor 25 is started, and the output end of the first motor 25 can drive the support base 21 to rotate the rotating table 22 as a whole, so as to realize the switching of the four groups of positioning cores 23 between the pressing station, the feeding station, the discharging station and the waiting station, greatly improving the continuous operation efficiency of the device. Further, the side of the pressing machine 1 close to the discharging station is provided with a discharging port 12; the pressing machine 1 can be additionally provided with a drying station, and the drying station is provided with a hot air blower, so as to facilitate rapid drying of the armature sheet after gluing.

[0028] After pressing an armature sheet, the second motor 26 is started, and the second motor 26 can directly drive the positioning core 23 to rotate relative to the rotating table 22, so as to accurately position the armature sheet on the positioning core 23, ensure the coaxiality requirement in the sheet pressing process, and finally realize the spiral accurate assembly of the armature sheet.

[0029] When the third motor 29 drives the screw rod 27 to rotate, the glue applying unit 3 is threadedly connected with the screw rod 27, and the glue applying unit 3 is fixedly connected with the pressing head 28, so that the pressing head 28 is driven to stably ascend and descend along the pressing direction, and a stable pressing force is provided for pressing the armature laminations.

[0030] In one embodiment of the present application, as shown in Figure 4 and Figure 5 the glue applying unit 3 comprises: a glue applying box 31, which is threadedly connected with the screw rod 27, and an upper side of which is provided with a glue inlet plug 311; a glue inlet pipe 32, which is communicated with a lower side of the glue applying box 31 through a one-way valve, and an inside of which is slidably connected with a first piston head 33 capable of sealing, and the first piston head 33 is connected with an inner wall of an end portion of the glue inlet pipe 32 through a first spring 35; a glue outlet cylinder 34, which is slidably connected with an inside of a lower side of the glue inlet pipe 32, and an upper end portion of which is connected with the first piston head 33, and an inside of the upper end portion of the glue outlet cylinder 34 is provided with a sealing unit 36, the sealing unit 36 is used for sealing glue passing through the glue inlet pipe 32 and the glue outlet cylinder 34, and the sealing unit 36 comprises: an embedded groove 361, which is arranged in the inside of the glue outlet cylinder 34; a baffle 362, which is rotatably connected with the inside of the embedded groove 361, and an arc surface 363 is arranged on a side surface of the baffle 362; and a sealing piece 364, which is slidably connected with the inside of the embedded groove 361, and one end of the sealing piece 364 is connected with the side surface of the baffle 362, and the other end portion of the sealing piece 364 is connected with an inner wall of the embedded groove 361 through a second spring 365.

[0031] By adopting the above technical scheme, before the glue applying operation, the glue inlet plug 311 is opened to inject a certain amount of glue into the glue applying box 31. When the third motor 29 drives the screw rod 27 to rotate to drive the glue applying box 31 to descend, the glue applying box 31 drives the pressing head 28 to descend through the glue inlet pipe 32 and the glue outlet cylinder 34, until the pressing head 28 contacts the surface of the uppermost group of armature laminations.

[0032] With the continuous pressing operation, the glue outlet cylinder 34 slides upward relative to the glue inlet pipe 32 under the resistance of the armature laminations, and then pushes the first piston head 33 to ascend along the inside of the glue inlet pipe 32 and compresses the first spring 35. In this process, the ascending of the first piston head 33 increases the pressure in the inside of the glue inlet pipe 32, so that the arc surface 363 pushes the sealing piece 364 to slide in the embedded groove 361 under the action of high pressure, and compresses the second spring 365 in the inside of the embedded groove 361. At this time, a glue flow channel is formed between the two baffles 362, and the glue in the glue inlet pipe 32 flows into the glue outlet cylinder 34 through the glue flow channel under the action of high pressure, and finally is applied on the surface of the armature laminations through the output end portion of the glue outlet cylinder 34.

[0033] In the process, by starting the second motor 26 of the press-fit station, the set of positioning cores 23 drive the armature laminations on the surface to rotate by a certain angle, so as to realize the spiral assembly of the armature laminations, and in the process of rotation, the glue can be uniformly applied to the surface of the armature laminations.

[0034] When the single press-fit gluing is completed, the third motor 29 drives the lead screw 27 in the opposite direction, drives the glue tank 31 to move upward along the press-fit direction, and the glue tank 31 synchronously drives the pressure head 28 to separate from the surface of the armature laminations through the glue inlet pipe 32 and the glue outlet cylinder 34. At this time, the resistance force borne by the pressure head 28 disappears, the elastic potential energy of the compressed first spring 35 is released, the first piston head 33 is pushed to reset downward along the inside of the glue inlet pipe 32, and at this time, the two sets of baffles 362 are closed to each other under the elastic force of the second spring 365, the glue flow channel formed between the two sets of arc surfaces 363 is closed, the sealing cutoff of the glue is realized, and the situation of glue dripping in the resetting process of the glue application unit is avoided. When the first piston head 33 slides downward along the inside of the glue inlet pipe 32, the glue in the glue tank 31 enters the inside of the glue inlet pipe 32 through the one-way valve on the upper end of the glue inlet pipe 32. The above working process is sequentially cycled to realize the continuous spiral press-fit gluing of the armature laminations.

[0035] Further, the glue tank 31 and the pressure head 28 are each installed with three sets, the inner wall of the press-fit machine 1 is provided with a guide groove for limiting the glue tank 31, and the stability of the glue tank 31 in lifting is improved.

[0036] In an embodiment of the present application, as shown in Figure 5 The pressure head 28 comprises: A pressure head frame 281 is fixed to the lower end surface of the glue outlet cylinder 34. An open slot 282 is provided on the pressure head frame 281, and two sets of rotating frames 283 are rotatably connected inside the open slot 282. A pressure head 284 is rotatably connected to the end of the rotating frame 283, and the two sets of pressure heads 284 are connected by elastic ropes 285.

[0037] By adopting the above technical scheme, when the pressure head 28 performs the pressing action with the gluing unit 3 moving downward, the pressure head 284 first contacts the upper surface of the armature sheet, and by virtue of the rotation cooperation between the rotating frame 283 and the pressure head frame 281, the two groups of pressure heads 284 can adaptively adjust the fitting angle according to the flatness of the surface of the armature sheet, so as to ensure that the pressure head 284 and the surface of the sheet form full and close contact, and avoid local uneven stress leading to deformation of the sheet. At the same time, the elastic rope 285 connected between the two groups of pressure heads 284 can provide a continuous pre-tightening force, so that the pressure head 284 is always in close contact with the surface of the sheet, further ensuring the uniformity of the pressing force transmission. The elastic property of the elastic rope 285 can also play a buffering role in the pressing process, and the elastic rope 285 can absorb part of the impact force through deformation, so as to avoid rigid damage to the armature sheet caused by instantaneous contact, and improve the stability of the pressing quality.

[0038] In the process of rotating the armature sheet with the positioning core 23 to realize spiral assembly, the pressure head 284 rotates on the surface of the armature sheet, at which time the pressure head 284 can uniformly apply glue on the upper surface of the armature sheet, ensuring the uniformity of the glue between the armature sheets. Further, the lower end surface of the pressure head 284 is attached with a wear-resistant rubber layer, which can increase the contact area between the pressure head 284 and the armature sheet, and at the same time reduce the wear during the pressing process, prolonging the service life of the pressure head 284.

[0039] In an embodiment of the present application, as shown in Figure 5 The adjusting unit 4 comprises: An adjusting cylinder 41 is threadedly connected to the surface of the glue outlet cylinder 34, and the outer surface of the adjusting cylinder 41 is provided with a convex pattern 411; A pressure sensor 42 is fixed to the upper end of the adjusting cylinder 41; A displacement sensor 43 is connected to the lower end of the glue inlet pipe 32, and the pressure sensor 42 and the displacement sensor 43 are electrically connected to the controller 11 on the pressing machine 1.

[0040] By adopting the above technical scheme, when the armature sheet is pressed, the glue inlet pipe 32 drives the displacement sensor 43 at the lower end thereof to slide downward synchronously, and the displacement sensor 43 can accurately detect the displacement amount of the gluing unit 3 driving the pressure head 28 to move downward, i.e. the pressing stroke data, which is also synchronously fed back to the controller 11.

[0041] When the pressure head 28 contacts the armature lamination, the glue outlet cylinder 34 slides upward in the inside of the glue inlet pipe 32 under the resistance of the armature lamination, at this time, the glue outlet cylinder 34 will drive the pressure sensor 42 at the upper end thereof to slide upward synchronously until the pressure sensor 42 contacts the displacement sensor 43 at the lower end of the glue inlet pipe 32, at this time, the pressure sensor 42 transmits the collected data to the controller 11, and the controller 11 controls the third motor 29 to be closed, thereby avoiding that the pressure head 28 excessively extrudes the armature lamination, causing the armature lamination to be damaged due to deformation.

[0042] The operator can increase the hand friction force by means of the convex patterns 411 on the outer surface of the adjusting cylinder 41, conveniently rotate the adjusting cylinder 41, realize the lifting movement of the adjusting cylinder 41 along the axial direction of the glue outlet cylinder 34 by means of the threaded cooperation between the adjusting cylinder 41 and the glue outlet cylinder 34, and further adjust the initial installation height of the pressure sensor 42, thereby completing the adjustment of the press-fit pressure value. Specifically, the distance between the pressure sensor 42 and the displacement sensor 43 is farther, and the press-fit pressure value of the pressure head 28 to the armature lamination is greater when the adjusting cylinder 41 is rotated downward.

[0043] In an embodiment of the present application, as shown in Figure 3 and Figure 4 , the side surface of the press-fit machine 1 is provided with an upper feeding unit 5 for feeding the armature lamination, and the upper feeding unit 5 comprises: a supporting plate 51 fixed on the side surface of the press-fit machine 1; a lamination seat 52 slidably connected to the surface of the supporting plate 51, and the lamination seat 52 is provided with a lamination groove 521 for placing the armature lamination; a pneumatic cylinder 53 installed on the upper side of the supporting plate 51, and the lamination seat 52 is connected to the output end of the pneumatic cylinder 53; a lamination seat groove 54 provided on the surface of the supporting plate 51 and in communication with the upper side of the lamination groove 521; a pushing frame 55 rotatably connected to the lamination seat 52; a sliding groove 56 provided on the lamination groove 521, and one end of the sliding groove 56 is provided with a magnet 57, and the lower end of the pushing frame 55 is slidably connected to the inside of the sliding groove 56.

[0044] By adopting the above technical scheme, when the armature lamination is press-fit, the armature lamination to be press-fit is first placed in the lamination groove 521, the pneumatic cylinder 53 is started, the lamination seat 52 is driven by the pneumatic cylinder 53 to reciprocate on the supporting plate 51, when the lamination seat 52 slides towards the pneumatic cylinder 53, the lamination seat 52 drives the armature lamination to slide as a whole through the lamination seat groove 54, and the lamination seat 52 drives the pushing frame 55 at the side thereof to slide in the sliding groove 56, when the pushing frame 55 slides to the end of the sliding groove 56, the pushing frame 55 is flipped to the vertical direction under the magnetic force of the magnet 57.

[0045] Afterwards, when the laminated seat 52 slides away from the air cylinder 53, the laminated seat 52 will drive the pusher 55 to slide synchronously until the pusher 55 contacts the side surface of the armature laminations, so that the group of armature laminations at the bottom of the laminated slot 521 will slide in the laminated seat slot 54 under the pushing of the pusher 55 until the pusher 55 pushes the group of armature laminations onto the positioning core 23 of the feeding station, realizing the automatic feeding of the armature laminations.

[0046] The working principle of the present application is that: first, the armature laminations to be pressed are placed in the laminated slot 521, the air cylinder 53 drives the laminated seat 52 to slide, and the armature laminations are pushed onto the positioning core 23 of the feeding station by the cooperation of the pusher 55 and the magnet 57; then the first motor 25 drives the support seat 21 to rotate the rotating table 22, and the positioning core 23 carrying the armature laminations is switched to the pressing station. In the pressing stage, the third motor 29 drives the screw 27 to rotate, driving the glue applying unit 3 and the pressing head 28 to move downward, the pressing head 28 is self-adapted to the surface of the armature laminations and applies pressure; at the same time, the glue applying unit 3 works synchronously with the pressing action, the first piston head 33 is pushed to open the glue flow channel after the glue outlet 34 is contacted, the glue is applied to the surface of the laminations through the glue outlet 34, and the second motor 26 drives the positioning core 23 to rotate the armature laminations, realizing the spiral assembly of the armature laminations and the uniform application of glue. At the same time, the displacement sensor 43 detects the pressing stroke, and the pressure sensor 42 collects the pressing pressure, and the data is fed back to the controller 11 to realize accurate control, and the operator can adjust the pressing pressure value by rotating the adjusting cylinder 41. After single pressing and gluing is completed, the sealing unit 36 closes the glue flow channel to avoid glue leakage; the first motor 25 continues to drive the rotating table 22 to switch the laminations completed with pressing to the discharge port 12, and the cycle is repeated in turn, realizing the continuous and automatic spiral pressing and gluing of the armature laminations.
