Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Example 1

[0036] Please see Figure 1-6 In this embodiment of the present invention, a surface polishing device for ductile iron parts includes: a support shell 100, a bearing mechanism 200, and a polishing mechanism 300. A fixed shell 110 is fixedly connected to the top of the support shell 100, and a rectangular hole 111 is provided on the fixed shell 110. A collecting component is provided at the bottom of the fixed shell 110. The bearing mechanism 200 is fixed on the fixed shell 110. The polishing mechanism 300 is provided on the support shell 100. The polishing mechanism 300 includes an annular shell 310. Two motors 370 are fixedly connected inside the annular shell 310. A screw 371 is fixedly connected to the output end of the motor 370. A moving rod 372 is screwed to the outside of the screw 371 and is slidably connected to the annular shell 310. A grinding wheel 373 is rotatably connected to one end of the moving rod 372. An adjustment component is provided on the outside of the annular shell 310.

[0037] Specifically, the bearing mechanism 200 is used to support and fix the ductile iron pipe. By starting two motors 370, the screw 371 is rotated, which moves the moving rod 372 and the grinding wheel 373 to the appropriate position. The adjustment component is then used to adjust the movement of the grinding wheel 373, which facilitates the polishing of the surface of ductile iron pipes of different sizes, making it more convenient to use.

[0038] like Figure 3-5 As shown, in this embodiment, the bearing mechanism 200 includes a fixed rod 210, one end of which is fixedly connected to the fixed shell 110. The fixed rod 210 has multiple sliding grooves 211, and the inner sidewall of each groove 211 has multiple sliding through holes 212 evenly distributed. A fixing assembly is fitted onto the fixed rod 210. The adjusting assembly includes a movable shell 320, a motor 340, two fixing plates 350, and two limiting rods 360. The movable shell 320 is rotatably connected to the outer side of the annular shell 310. The motor 340 is fixedly connected to the fixed shell 110. The output end of the motor 340 passes through the sidewall of the fixed shell 110 and is fixedly connected to a screw 341. A screw tube 342 is screwed onto the outer side of the screw 341. The tube 342 is fixedly connected to the movable shell 320. Both fixed plates 350 are fixedly connected to the movable shell 320. Multiple rotating balls 351 are rotatably connected to the fixed plates 350. Two limiting rods 360 are fixedly connected to the two inner walls of the fixed shell 110 respectively. Limiting grooves 361 are provided on the limiting rods 360, and the limiting grooves 361 are slidably connected to the corresponding rotating balls 351. A second motor 321 is fixedly connected to one inner wall of the movable shell 320, and a gear 322 is fixedly connected to the output end of the second motor 321. A fixed ring 330 is fixedly connected to one side of the annular shell 310, and the fixed ring 330 is rotatably connected to the inner wall of the movable shell 320. A toothed ring 331 is sleeved and fixed on the fixed ring 330, and the toothed ring 331 meshes with the gear 322.

[0039] In this embodiment, the fixed rod 210 is used to facilitate the support of the ductile iron pipe. After both grinding wheels 373 are in contact with the surface of the ductile iron pipe, the motor 340 is started, which drives the screw 341 to rotate. The fixed plate 350, rotating ball 351, limiting rod 360 and limiting groove 361 are used in combination to limit the movement of the movable shell 320, thereby allowing the screw tube 342, movable shell 320, annular shell 310 and grinding wheel 373 to move. Then the motor 2 is started. 321, the motor 321 drives the gear 322 to rotate, and the gear 322 meshes with the gear ring 331, thereby causing the fixed ring 330, the annular shell 310 and the two grinding wheels 373 to rotate. The two moving and rotating grinding wheels 373 facilitate the polishing of the ductile iron pipe surface. By adjusting the position of the grinding wheels 373, the polishing mechanism 300 can polish the surface of ductile iron pipes of different sizes, thereby improving the practicality of the ductile iron surface polishing device.

[0040] The two motors 370 can be powered by a battery installed inside the annular housing 310, or by installing electric slip rings inside the movable housing 320 and outside the annular housing 310, and by using the two electric slip rings in combination.

[0041] like Figure 1-2 As shown, in this embodiment, baffles 120 are rotatably connected to both ends inside the rectangular hole 111. The collection assembly includes a collection shell 130 and a guide plate 140. The collection shell 130 is slidably connected to the bottom of the fixed shell 110, and the guide plate 140 is fixedly connected to the bottom of the inner side of the fixed shell 110. Multiple drop holes 141 are provided on the guide plate 140.

[0042] In practice, when the two baffles 120 are closed, the fixed shell 110 and the two baffles 120 can prevent the debris from flying to the outside of the fixed shell 110 during grinding. The guide plate 140 can guide the falling debris, and the multiple dropping holes 141 can make the debris fall into the collection shell 130. The collection shell 130 can then be used to collect and store the debris, making it more convenient to use.

[0043] Example 2

[0044] Based on Example 1, in order to support and fix ductile iron pipes of different sizes.

[0045] like Figure 3-4 As shown, in this embodiment, the fixing assembly includes: a motor 220, multiple bidirectional lead screws 230, and multiple fixing blocks 240. The motor 220 is fixedly connected to the fixing shell 110. The output end of the motor 220 passes through the side wall of the fixing shell 110 and is fixedly connected to a round rod 221. The round rod 221 is rotatably connected to the fixing rod 210. The multiple bidirectional lead screws 230 are all sleeved and fixed on the outside of the bidirectional lead screws 230. The two ends of the bidirectional lead screws 230 are screwed and connected to sliding plates 231. Multiple support rods 232 are rotatably connected to the sliding plates 231. The multiple fixing blocks 240 are all located on the outside of the fixing rods 210. The two ends of the fixing blocks 240 are rotatably connected to the corresponding support rods 232. Rubber pads 241 are glued and fixed on the fixing blocks 240.

[0046] In specific implementation, by starting motor 220, the slide groove 211 is rotated, which in turn causes multiple bidirectional lead screws 230 to rotate. The rotation of the bidirectional lead screws 230 causes two sliding plates 231 on them to slide and connect inside the slide groove 211. The moving sliding plates 231 cause multiple support rods 232 to move, which facilitates the adjustment of the position of the fixing block 240 and the rubber pad 241. The multiple fixing blocks 240 and multiple rubber pads 241 adjusted to the appropriate position facilitate the support of the ductile iron pipe. By adjusting the position of the multiple fixing blocks 240 and multiple rubber pads 241, the bearing mechanism 200 can be adapted to ductile iron pipes of different sizes.

[0047] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0048] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
