DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-3 The first embodiment shown is a silicon steel sheet processing device for permanent magnet synchronous motor production, comprising a base 1, a processing assembly for processing silicon steel sheets for permanent magnet synchronous motor production is installed on the upper end of the base 1, and the processing assembly comprises: a positioning assembly 2, which is arranged in the middle of the upper end of the base 1 and is used for positioning the silicon steel sheet;

[0024] The electric slide rail 3 is installed on the top of the base 1 and is slidably connected to the slide seat 4. The bottom of the slide seat 4 corresponds to the upper end of the positioning assembly 2 and is connected to the second cylinder assembly 5; the processing assembly 6 is installed at the bottom of the second cylinder assembly 5 for drilling holes in the silicon steel sheet. The processing assembly 6 includes a drill 61 fixedly connected to the bottom extension end of the second cylinder assembly 5. A spray plate 62 is installed on the lower side of the drill 61 near the outer side of its drill bit end. A shielding frame 63 is slidably connected to the edge of the spray plate 62, and a bellows 64 is connected to the upper edge of the spray plate 62;

[0025] The water supply component 7 is installed at the edge of the base 1 and the water outlet end is connected to the bellows 64; the base 1 is slidably connected to two sets of recovery boxes 8 at the front and rear sides close to the positioning component 2; the diameter of the drill 61 is smaller than the diameter of the shielding frame 63, and the inner end of the shielding frame 63 is provided with an anti-slip groove slidably connected to the edge of the spray plate 62; the middle part of the spray plate 62 is provided with a circular groove near the drill bit end of the drill 61, and a plurality of spray holes are provided on the lower side of the spray plate 62. The inside of the spray plate 62 is hollow and connected to the bellows 64 and the spray holes respectively. A water pump connected to the base 1 is provided in the water supply component 7, and a bifurcated pipe fixedly connected to the bellows 64 is provided at the water outlet of the water pump, and a water pumping pipe is installed at the water pumping end of the water pump;

[0026] The shielding frame 63 is made of stainless steel. The height of the processing assembly 6 is adjusted by the second cylinder assembly 5 so that the processing assembly 6 can be used to drill holes in the silicon steel sheet. During the downward movement of the drill 61, the bottom of the shielding frame 63 first contacts the silicon steel sheet. The reaction force of the silicon steel sheet causes the shielding frame 63 to slide relative to the edge of the spray plate 62, and the inner side of the shielding frame 63 blocks the splashing debris generated by the drilling of the silicon steel sheet to reduce dust pollution and safety hazards. During the drilling process, the water pump in the water supply component 7 is turned on. The water pump draws water from the outside and sprays the inner wall of the shielding frame 63 and the drill bit end of the drill 61 through the bifurcated pipe, the bellows 64, and the spray plate 62 to spray the inner wall of the shielding frame 63 and the drill bit end of the drill 61, so that the drilling debris falls off, and then the drill bit end of the drill 61 is separated from the silicon steel sheet. At this time, the shielding frame 63 is reset under the action of gravity, and the bottom is still in contact with the silicon steel sheet. The shielding frame 63 cooperates with the electric slide rail 3 to sweep the mixture of water and debris impurities into the recovery box 8;

[0027] like Figure 1-3 The second embodiment shown is mainly different from the first embodiment in that:

[0028] The positioning assembly 2 includes a processing table 21 fixedly connected to the middle of the base 1, and a first cylinder assembly 22 is provided on the left and right sides of the processing table 21. A clamping plate 23 is fixedly connected to the middle of the processing table 21 on the extended side of the first cylinder assembly 22. The upper end of the clamping plate 23 is slidably connected to a limit frame 26. The limit frame 26 is slidably connected to a slide frame 25 away from the middle of the processing table 21. The upper end of the slide frame 25 is connected to an electric push rod assembly 24 connected to the processing table 21.

[0029] Limiting grooves are vertically provided on both sides of the clamping plate 23, and the limiting frame 26 is slidably connected to the clamping plate 23 through the limiting grooves. A pressure strip is installed on the limit frame 26 near the middle of the processing table 21, and a baffle is provided at the end of the pressure strip away from the limit frame 26. A sliding groove slidably connected to the limit frame 26 is provided in the middle of the slide frame 25. The two groups of clamping plates 23 are driven by the first cylinder assembly 22 to clamp and position the two sides of the silicon steel sheet. After the clamping plate 23 is clamped, the electric push rod assembly 24 drives the slide frame 25 and the limiting frame 26 to move downward, and the pressure strip at the end of the limiting frame 26 limits the edge of the silicon steel sheet, thereby improving the positioning accuracy of the silicon steel sheet.

[0030] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0031] During use, the user places the silicon steel sheet to be processed in the middle of the processing table 21, and drives the two sets of clamping plates 23 to clamp and position the two sides of the silicon steel sheet through the first cylinder assembly 22. During the movement of the clamping plate 23, the clamping plate 23 drives the limit frame 26 to slide along the slide frame 25. After the clamping plate 23 is clamped, the slide frame 25 and the limit frame 26 are driven downward by the electric push rod assembly 24. The pressure strip at the end of the limit frame 26 limits the edge of the silicon steel sheet, and then the slide seat 4, the second cylinder assembly 5, and the processing assembly 6 are moved to the upper end of the silicon steel sheet to be processed through the electric slide rail 3. The drill 61 is turned on and the second cylinder assembly 5 is used to move the processing assembly 6 to the upper end of the silicon steel sheet to be processed. The cylinder assembly 5 adjusts the height of the processing assembly 6 so that the drilling end of the drill 61 drills the silicon steel sheet. During the downward movement of the drill 61, the bottom of the shielding frame 63 first contacts the silicon steel sheet. The reaction force of the silicon steel sheet causes the shielding frame 63 to slide relative to the edge of the spray plate 62, and the inner side of the shielding frame 63 blocks the debris generated by the drilling of the silicon steel sheet. During the drilling process, the water pump in the water supply component 7 is turned on, and the water pump draws external water and sprays the inner wall of the shielding frame 63 and the drill end of the drill 61 through the bifurcated pipe, the bellows 64, and the spray plate 62 to cause the drilling debris to fall off. The drill 61 is closed and each link is reset.
