DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The technical solution of the present invention will be clearly and completely described below in conjunction with 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Refer to Figures 1 to 6 , the present invention provides a technical solution: a numerically controlled sawing machine for machining the attached pole core of a motor, including an operation table 14 with a hollow interior. A guide plate 9 is inclinedly arranged on one side of the operation table 14, and a support base 1 inclinedly arranged is connected in a lifting manner on the side of the operation table 14 away from the guide plate 9. Driving disks 23 rotatably connected thereto are symmetrically arranged on the top of the support base 1. A second motor 27 is connected to one side of the driving disk 23. A saw band 24 in a ring structure is connected between the driving disks 23. A top cover 2 for protecting the driving disk 23 is rotatably connected to the top of the support base 1. The top cover 2 is connected to the support base 1 through a rotating shaft, and the other side of the top cover 2 is connected to the support base 1 through a buckle, so as to facilitate the rotation and opening of the top cover 2, facilitating the staff to maintain and replace the saw band 24, bringing great convenience to the user.

[0028] As Figure 2 , 4 shown, a first connecting frame 25 with a U-shaped structure and an upward opening is arranged at the bottom of the operation table 14. The top of the first connecting frame 25 penetrates the operation table 14 and is fastened to the bottom of the support base 1. A third electric push rod 37 is vertically connected between the top surface of the first connecting frame 25 and the inner top surface of the operation table 14. The third electric push rod 37 pushes the first connecting frame 25 to lift and adjust to drive the support base 1 to lift and adjust, which can ensure the normal cutting of the saw band 24. At the same time, in order to prevent the saw band 24 from deflecting during operation, two groups of brackets 3 symmetrically distributed are arranged between the two driving disks 23. The brackets 3 are fastened to the top of the operation table 14. The number of each group of brackets 3 is two. During use, the saw band 24 is placed between the two brackets 3 for limit fixation, so that the saw band 24 can effectively cut from top to bottom. At the same time, a plurality of rollers 7 are rotatably connected to the side wall of each bracket 3. Under the guiding action of the rollers 7, not only effective guiding is achieved, but also the friction between the saw band 24 and the bracket 3 can be reduced.

[0029] As Figure 5 , 6As shown in the figure, a plurality of through slots 10 for discharging materials are provided at the top of the material guide plate 9 and the operating table 14 on one side thereof. A material guide seat 18 is connected inside the operating table 14 and is located directly below the through slots 10. A strip-shaped box body 32 is communicated with the bottom of the material guide seat 18, and a collection box 30 is connected to one side of the strip-shaped box body 32 and the material guide seat 18. The strip-shaped box body 32, the material guide seat 18 and the collection box 30 form a sealed space. A blanking hopper 11 for collecting debris is slidably connected inside the strip-shaped box body 32, and the connection between the collection box 30 and the strip-shaped box body 32 and the material guide seat 18 is separated by a partition plate 6.

A second electric push rod 33 is connected between one side of the scraper 21 and the material guide seat 18. A magnetic attraction block 38 is connected to the bottom of the material guide seat 18.

[0030] During processing, after the debris generated by the cutting process of the iron core and the mixture formed with the coolant are discharged to the top of the material guide seat 18, since the top of the material guide seat 18 is arranged in an inclined structure, it is convenient for the coolant to quickly fall, and the magnetic attraction block 38 arranged on the top of the material guide seat 18 can adsorb the iron filings, realizing solid-liquid separation. The debris is adsorbed on the top of the magnetic attraction block 38, and the coolant flows into the collection box 30. After long-term use, the iron filings accumulate. The second electric push rod 33 pushes the scraper 21 to slide on the top of the material guide seat 18, and the accumulated debris can be pushed into the blanking hopper 11 for collection, which brings great convenience to the cleaning work.

[0031] As Figure 5 , 6 shown in the figure, the bottom of the strip-shaped box body 32 is connected to a liquid collection barrel 29 through a connecting pipe 12. Two liquid collection barrels 29 are provided and are used for containing coolant inside. A water pump 34 is connected between the two liquid collection barrels 29. A plurality of connecting pipes 12 are provided and the bottom thereof is connected to a second transport pipe 31. The bottom of the second transport pipe 31 is connected to one of the liquid collection barrels 29. A first mounting frame 8 is connected to the top of the operating table 14.

The other end of the first transport pipe 5 is connected to the other liquid collection barrel 29. The coolant discharged from the inside of the collection box 30 falls into one of the liquid collection barrels 29 and is recycled under the action of the water pump 34. At the same time, in order to prevent the residual iron filings from clogging the spray heads 26, an annular seat 41 is connected inside the liquid collection barrel 29 connected to the second transport pipe 31, and a leakage plate 40 is arranged on the top of the annular seat 41, so that the leakage plate 40 can achieve secondary filtration.

[0032] In summary, the numerically controlled sawing machine for processing the attached pole iron core of the motor further includes a control box 13. A controller is arranged inside the control box 13. The first electric push rod 15, the first motor 19, the second motor 27, the second electric push rod 33, the third electric push rod 37, and the third motor 39 are all connected to the controller. During use, clamping plates 28 are symmetrically arranged on the top of the operating table 14, and the clamping plates 28 are located on the side of the support base 1 away from the material guiding plate 9. A strip-shaped groove 4 is opened on the top of the operating table 14. A second connecting frame 35 with a U-shaped structure and an upward opening is arranged inside the operating table 14. The top end of the second connecting frame 35 penetrates through the strip-shaped groove 4 and is connected to the bottom of the clamping plate 28.

The third motor 39 drives the two clamping plates 28 to slide towards each other, so as to clamp the side wall of the iron core and ensure stable cutting of the iron core.

[0033] At the same time, a second mounting frame 22 fastened to the operating table 14 is arranged above the clamping plate 28. The first motor 19 is fixedly connected to the second mounting frame 22. The output end of the first motor 19 is connected to a cross plate 16. A pressing plate 20 is arranged below the cross plate 16. The first electric push rod 15 is fastened between the pressing plate 20 and the cross plate 16. The first motor 19 drives the cross plate 16 and the pressing plate 20 to rotate, so that the pressing plate 20 can adjust the placement angle of the pressing plate 20 according to the number of clamped iron cores, and then the pressing plate 20 can normally press the top of the iron core. In order to realize the normal lifting of the pressing plate 20, a plurality of guide tubes 17 are connected between the pressing plate 20 and the cross plate 16. The number of each group of guide tubes 17 is two and they are coaxially telescopically connected.

[0034] The clamped and stable iron core is cut driven by the saw band 24 arranged for lifting. During cutting, the coolant is sprayed onto the saw band 24 through the nozzle 26 to cool the cutting operation. The generated iron chips and the used coolant flow to the top of the material guiding seat 18. The iron chips can be adsorbed by the magnetic attraction block 38, and the coolant flows into the liquid collecting bucket 29 for recycling. The adsorbed iron chips can be quickly cleaned by scraping with the scraping plate 21.
