[0027] Referring to Figures 1-3 As shown in the drawings, a motor stator-rotor lamination punching machine capable of reducing debris splashing includes a machine shell 1, a feeding unit 2 arranged on the machine shell 1, a rotating table 3 for receiving materials and a material placing block 31 for placing materials, a lifting drilling mechanism 4 for drilling the materials, an extension cylinder 41 for pressing the materials against the rotating table 3 and an extension rod 42 arranged at the output end of the extension cylinder 41, and a shielding mechanism 5 arranged on the machine shell 1 for shielding the debris during the drilling process, the shielding mechanism 5 including a shielding plate 51 and a shielding piece 52, and a driving mechanism 6 for driving the shielding plate 51 and the shielding piece 52 to tilt.

[0028] A first rotating driver 311 is arranged on the machine shell 1 for driving the rotating table 3 to rotate, the output end of the first rotating driver 311 is provided with a first gear pair 312, the lifting drilling mechanism 4 includes a jacking cylinder 411 and a rotating head 412 arranged at the output end of the jacking cylinder 411, and a second rotating driver 413 and a second gear pair 414 arranged on the machine shell 1 for driving the jacking cylinder 411 to rotate, the jacking cylinder 411 is rotatably arranged on the machine shell 1 through a bearing, so that the jacking cylinder 411 can drive the rotating head 412 to rotate. A discharging mechanism 8 is further arranged on the machine shell 1 for discharging the materials after drilling. When stamping and drilling the materials on the rotating table 3, first, the extension cylinder 41 is started to drive the extension rod 42 to press the materials on the rotating table 3 against the material placing block 31. Then, the jacking cylinder 411 is started to drive the rotating head 412 to descend in the vertical direction until the rotating head 412 contacts the drilling position of the materials on the material placing block 31. Then, the second rotating driver 413 is started to drive the jacking cylinder 411 to rotate through the second gear pair 414. The jacking cylinder 411 can perform stamping and drilling of the materials on the material placing block 31 in rotation and descent. In this process, debris is generated. During the pressing and sliding of the extension rod 42 on the materials, the shielding mechanism 5 can be driven by the driving mechanism 6 to shield the drilling area, avoiding the splashing of debris during drilling, and automatically blocking the splashing debris without manual driving of the shielding mechanism 5.

[0029] Referring to Figure 3 and Figure 5 As shown in the drawings, the shielding mechanism 5 further includes an adsorption plate 53; the adsorption plate 53 has a pair of and is arranged on the extension rod 42 respectively; the lower surface of the adsorption plate 53 is attached to the upper surface of the rotating table 3.

[0030] The adsorption plate 53 is preferably a magnetic block, which has good adsorption force and can adsorb the drillings generated in the drilling process. When the extension rod 42 tightly abuts against the material, the adsorption plate 53 can synchronously move. When the extension rod 42 tightly abuts against the material on the material placing block 31, the adsorption plate 53 can cover the rotary table 3 and shield the drilling area, so that the drillings generated in the drilling process are attached to the adsorption plate 53.

[0031] Referring to Figure 5 As shown in the figure, the driving mechanism 6 comprises a setting frame 61, a positioning column 62 and a hinged rod 63. The setting frame 61 has a pair of and is respectively arranged on the casing 1. The pair of setting frames 61 are located on both sides of the telescopic cylinder 41. The positioning column 62 has a pair of and is respectively arranged on the setting frame 61. The positioning column 62 is rotationally connected with the shielding plate 51. One end of the hinged rod 63 is rotationally connected with the output end of the telescopic cylinder 41. The other end of the hinged rod 63 is rotationally connected with the shielding plate 51. When the extension rod 42 is extended, the shielding plate 51 is in an inclined state close to one side of the rotary table 3 through the transmission of the hinged rod 63.

[0032] During the process that the extension rod 42 tightly abuts against the material, the shielding plate 51 and the shielding sheet 52 can be driven to swing along the positioning column 62 through the hinged rod 63, until the shielding plate 51 and the shielding sheet 52 cover the rotary table 3 and the material placing block 31. When the rotary head 412 rotates to drill, the drillings will not splash outside the shielding plate 51 and the shielding sheet 52.

[0033] Referring to Figure 6 and Figure 7 As shown in the figure, the motor stator-rotor punching machine further comprises a scraping mechanism 7 arranged on the casing 1 for scraping the drillings on the adsorption plate 53. The scraping mechanism 7 comprises a mounting frame 71 and a contact scraping plate 72. The mounting frame 71 has a pair of and is respectively arranged on the casing 1 with the center point of the telescopic cylinder 41. The pair of mounting frames 71 are adjacent to one side of the setting frame 61.

[0034] After the rotary head 412 finishes the rotary drilling work and is lifted by the jacking cylinder 411, the extension rod 42 is retracted. During the retraction process, the contact scraping plate 72 arranged on the mounting frame 71 can scrape the drillings adsorbed on the adsorption plate 53.

[0035] Referring to Figure 6As shown, the scraping mechanism 7 further comprises a linear driver 73, a guide rod 74, a screw rod 75 and a moving scraping rod 76; the linear driver 73 has a pair of drivers respectively arranged on the mounting frame 71; the screw rod 75 is rotationally arranged on the mounting frame 71 and connected with the output end of the linear driver 73; the guide rod 74 has a pair of rods respectively arranged on the mounting frame 71 and in a cylindrical shape; and the moving scraping rod 76 is horizontally slidably arranged on the guide rod 74 and the screw rod 75.

[0036] When the extension rod 42 is in the retracted state, the linear driver 73 is started to drive the screw rod 75 to rotate, and the moving scraping rod 76 is driven to slide horizontally along the guide rod 74, so that the residual waste on the adsorption plate 53 can be scraped off, and the adsorption plate 53 can be kept clean. When the extension rod 42 is in contact with the scraping plate 72, the adsorption waste on the adsorption plate 53 can be scraped off, and the area not scraped off by the moving scraping rod 76 can be cleaned, so that the adsorption effect of the adsorption plate 53 on the waste is ensured.

[0037] Referring to Figures 1-7 As shown, the scraping mechanism 7 further comprises a collection box 77, a dust collection box 78, a dust collection pipe 79 and an air blower 791; the collection box 77 is arranged on the machine shell 1 and located between the pair of mounting frames 71; the dust collection box 78 is arranged on the machine shell 1 and close to one side of the telescopic air cylinder 41; the dust collection pipe 79 is arranged on the collection box 77 and connected with the dust collection box 78; and the air blower 791 is arranged on the machine shell 1 and connected with the dust collection box 78.

[0038] The dust collection box 78 is provided with a cover plate, and the connection end of the dust collection pipe 79 and the air blower 791 is provided with a filter screen for preventing the waste from being directly sucked into the air blower 791. The dust collection box 78 is used for collecting the waste, and when the contact scraping plate 72 and the moving scraping rod 76 scrape off the waste, the scraped waste can fall into the collection box 77. At this time, the air blower 791 is started to suck the waste in the collection box 77 through the dust collection pipe 79 and collect it into the collection box 77, and the waste collected in the dust collection box 78 can be poured out by opening the cover plate.

[0039] The working principle is that when the material on the rotating table 3 is punched and drilled, the telescopic air cylinder 41 is first started, and the extension rod 42 tightly abuts the material against the material block 31. Then, the lifting air cylinder 411 drives the rotating head 412 to descend to contact the material drilling position, and then the second rotating driver 413 drives the rotating head 412 to rotate and descend for punching and drilling through the second gear pair 414. In this process, waste will be generated. In order to control the waste splashing, when the extension rod 42 abuts against the material, the shielding plate 51 and the shielding piece 52 are driven to tilt and swing along the positioning column 62 through the hinged rod 63, cover the rotating table 3 and the material block 31, and prevent the waste from splashing. The adsorption plate 53, preferably a magnetic block, moves with the extension rod 42 and covers the rotating table 3 to adsorb the waste. After the drilling is completed, the lifting air cylinder 411 is lifted, and the extension rod 42 is retracted, at which time the contact scraping plate 72 on the mounting frame 71 scrapes the waste on the adsorption plate 53. Then, the linear driver 73 drives the lead screw 75 to rotate, so that the moving scraping rod 76 slides along the guide rod 74 to further clean the adsorption plate 53, and the scraped waste falls into the collection box 77. The dust collection box 78 collects the scraped waste through the dust collection pipe 79 and the air blower 791, and the filter screen prevents the waste from being directly sucked into the air blower 791. The collection box 77 collects the waste, and the cover plate of the dust collection box 78 is opened to dump the waste.

It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
