[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0041] According to the following Figure 3 - Fig.16The invention describes a device for removing rust from the surface of a circular stainless steel casting provided by an embodiment of the invention.

[0042] Embodiment 1:

[0043] The embodiment of the present invention provides a circular stainless steel casting surface rust removal device, including a shell 200 and a grinding head 800 arranged in the shell 200, and the grinding head 800 has a rotating shaft 820, and the rotating shaft 820 is fixed at the center of the grinding head 800. There is an inclination angle between the rotating shaft 820 and the surface of the stainless steel casting, so when the rotating shaft 820 rotates, it can grind the stainless steel casting in an inclined grinding manner, so that the flying chips generated by the grinding head 800 during grinding are subjected to the centrifugal force in the direction of the plane perpendicular to the rotating shaft 820, and this plane is inclined, so the direction in which the flying chips are thrown out is inclined relative to the grinding surface, and then the flying chips thrown out by the centrifugal force are blocked by the shell 200, thereby avoiding the situation where rust chips and other flying chips are splashed out and cause injuries.

[0044] Therefore, the circular stainless steel casting surface rust removal device provided in this embodiment can prevent flying chips generated by grinding from splashing out, thereby ensuring the safety of the grinding personnel.

[0045] Optionally, the inclination angle of the rotating shaft 820 is greater than 0° and less than 90°.

[0046] Preferably, the inclination angle of the rotating shaft 820 is 30°-60°.

[0047] The rotation of the rotating shaft 820 is preferably driven by a power assembly, and the power assembly mentioned here is disposed in the housing 200 , so that the grinding head 800 can rotate around the rotating shaft 820 as a circle center.

[0048] In order to facilitate the installation of the grinding head 800 , the grinding head 800 is equipped with a grinding seat 810 , and the grinding head 800 is assembled on the grinding seat 810 , and the rotating shaft 820 is assembled on the center of the grinding seat 810 by welding or bolting.

[0049] Optionally, the grinding head 800 is a grinding wheel or a grinding wire.

[0050] like Figure 3 The grinding wheel mentioned here is a circular grinding wheel with a through hole in the center, which is made of diamond abrasive as raw material and metal powder, resin powder, ceramic and electroplated metal as binders; when the grinding wheel is selected as the grinding head 800, in order to increase the contact area between the grinding wheel and the stainless steel casting, it is preferred to make the lower surface of the grinding wheel into a conical structure, and the outer arc surface of the conical structure can be completely fitted to the grinding surface of the stainless steel casting, thereby increasing the grinding area.

[0051] like Figure 4The grinding wire mentioned here is preferably a stainless steel corrugated wire. The stainless steel corrugated wire forms a spherical or conical structure, which can also increase the grinding area.

[0052] like Figure 3 The grinding head 800 mentioned above is a set, and the grinding head 800 is located in the middle of the housing 200, the rotating shaft 820 is tilted and assembled in the housing 200 through the bearing seat, and one end of the rotating shaft 820 is fixed at the center of the grinding seat 810; the power component is a single motor 900, which is fixed in the housing 200 and is used to drive the rotating shaft 820 to rotate. When the grinding head 800 is grinding, Figure 3 Looking down from the perspective shown Figure 3 The rotation direction of the rotating shaft 820 should be clockwise, and the flying chips generated by it can hit the left inner wall of the shell 200, and then the shell 200 can prevent the flying chips from splashing out.

[0053] Combination Figure 5 - Figure 7 As shown, in order to facilitate the rust removal of the surface of the circular stainless steel casting, the device is also equipped with an equipment frame 100, which includes a base 140 for placing the circular stainless steel casting, a top seat 110 is provided above the base 140, and the top seat 110 is fixedly connected to one side of the base 140 by a column 130 to form the main part of the equipment, and preferably a diagonal brace support is assembled between the top seat 110 and the column 130 to improve the stability of the top seat 110.

[0054] A spiral disk 150 is also suspended below the top seat 110 through a suspension rod 190, and a tooth portion is provided on the outer surface of the spiral disk 150, and a spiral slide groove with the same path as the spiral disk 150 is provided on the lower surface of the top seat 110, and a slidable slider 160 is provided in the spiral slide groove, and a spiral motor 170 is fixed to the lower end of the slider 160. The spiral motor 170 is used to drive the travel gear 180 to rotate so that the travel gear 180 rolls along the tooth portion. When the travel gear 180 rolls along the tooth portion, it can move along the spiral path of the spiral disk 150. When a support rod 300 is provided between the outer shell 200 and the travel gear 180, the support rod 300 can be used to drive the outer shell 200 to move in a spiral manner, and then the grinding component in the outer shell 200 can remove rust on the surface of the circular stainless steel casting in a spiral motion.

[0055] In addition, it is best that the screw motor 170 is equipped with a motor housing on the outside and the slider 160 is fixed to the motor housing.

[0056] Preferably, the cross section of the slider 160 is T-shaped to prevent the slider 160 from falling downward from the spiral chute.

[0057] Combination Figure 6 and Figure 7As shown, the support rod 300 mentioned above includes a rod 340 and a rod 310, the lower end of the rod 340 is fixedly connected to the housing 200, the lower end of the rod 310 is inserted into the rod 340, and a pressure spring 330 is installed between the lower end of the rod 310 and the lower end of the rod 2 340, so that the pressure spring 330 can give a downward pressure to the rod 310 and the housing 200, so that the grinding component can exert pressure on the grinding surface of the stainless steel casting during grinding, thereby improving the polishing finish.

[0058] Of course, the support rod 300 may not be used here, but a state in which its height can be actively adjusted may be used, for example, a hydraulic cylinder, a pneumatic cylinder or an electric telescopic rod may be fixed at the lower end of the travel gear 180 .

[0059] The above-mentioned device for supporting the lower polishing shell 200 for convenient polishing of the round stainless steel is provided. Of course, this embodiment does not necessarily adopt such a device, and the polishing can also be carried out in a handheld manner, for example Figure 8 The handheld structure shown has a handle frame 720 disposed on the housing 200, and a handle 710 is assembled at the end of the handle frame 720 away from the housing 200. The position of the grinding component (the housing 200 and all components therein) can be moved by holding the handle 710 to grind different positions of the stainless steel casting.

[0060] Embodiment 2:

[0061] Reference Fig. 9 - Fig.11 As shown, different from the first embodiment, in this embodiment, there are multiple groups of grinding heads 800, and the diameter of the grinding heads 800 in this embodiment is smaller than that of the grinding heads 800 in the first embodiment, and these small grinding heads 800 are arranged in the lower edge area of ​​the housing 200, and each grinding head 800 is provided with a rotating shaft 820, and multiple groups of rotating shafts 820 form a truncated cone structure that is narrow at the top and wide at the bottom; the power assembly is used to drive each group of rotating shafts 820 to rotate, so that multiple groups of grinding heads 800 can grind synchronously. Therefore, due to the synchronous grinding of multiple grinding heads 800, on the one hand, the grinding area can be increased, thereby improving the grinding efficiency, and on the other hand, the flying chips generated by each grinding head 800 in the multiple grinding heads 800 during grinding hit the inner wall of the corresponding housing 200, so that the flying chips can be evenly blocked by the housing 200. Compared with the long-term impact of flying chips on a single position of the housing 200 in the first embodiment, this method can improve the uniformity of the force of the housing 200 and improve the life of the housing 200.

[0062] Combination Fig.11 and Fig.12As shown, in this embodiment, the power component includes a main drive shaft 490, which is arranged at the upper center line of the outer shell 200, and an umbrella-shaped gear ring 450 is fixedly provided at the lower end of the main drive shaft 490, and a driven umbrella wheel 480 capable of engaging with the umbrella-shaped gear ring 450 is provided at the upper end of the rotating shaft 820. Then, when the main drive shaft 490 drives the umbrella-shaped gear ring 450 to rotate, the driven umbrella wheel 480 can rotate on its own, and the rotation of the driven umbrella wheel 480 can make the rotating shaft 820, the grinding seat 810 and the grinding head 800 rotate synchronously, and finally the grinding operation of the grinding head 800 is realized; in order to realize the active rotation of the main drive shaft 490, a driving structure 410 is also provided here, and the driving structure 410 is arranged at the upper part of the outer shell 200, and the driving structure 410 is used to drive the main drive shaft 490 to rotate on its own.

[0063] Preferably, in order to reduce the weight of the whole machine, the umbrella gear ring 450 is set as an annular umbrella gear ring, and a corresponding frame is provided inside it, and the lower end of the main drive shaft 490 is fixed at the center position of the frame.

[0064] In addition, there are a large number of grinding heads 800 and a large number of internal transmission structures. Therefore, once the stability of the grinding head 800 is insufficient, it will affect the grinding effect, such as the situation where the grinding surface is not smooth. Therefore, the grinding head 800 needs to be stably assembled. First, the rotational stability of the main drive shaft 490 needs to be ensured. It is preferred to equip the main drive shaft 490 with a bearing seat 430. The bearing seat 430 is welded or fixed to the upper end of the outer shell 200 by bolts, and the bearing seat 430 and the main drive shaft 490 are connected by a bearing to ensure the rotational stability of the main drive shaft 490.

[0065] Secondly, it is also necessary to ensure the stability of the rotating shaft 820 during rotation, so the rotating shaft 820 is equipped with a bearing seat 2 440 and a bearing seat 3 460, where the bearing seat 2 440 is fixed to the bottom of the bearing seat 1 430 by a pull rod, and the bearing seat 2 440 is provided with an upper through hole 441 for the rotating shaft 820 to pass through, a bearing is provided between the upper through hole 441 and the rotating shaft 820, and the bearing seat 2 440 is located above the driven umbrella wheel 480 to initially maintain the rotation stability of the rotating shaft 820; the above-mentioned bearing seat 3 460 is located below the driven umbrella wheel 480, and the outer edge of the bearing seat 3 460 is fixed to the inner wall of the outer shell 200, and the bearing seat 3 460 is provided with a lower through hole 461 for the rotating shaft 820 to pass through, and the lower through hole 461 and the rotating shaft 820 are connected by a bearing to maintain the lower stability of the rotating shaft 820.

[0066] Therefore, this solution can improve the grinding stability of the grinding head 800 and avoid the situation where the surface of the stainless steel casting after grinding is uneven or not smooth.

[0067] Combination Fig.11 and Fig.13 - Fig.15As shown, during the grinding process, the flying chips from the inclined grinding head 800 are intercepted by the outer shell 200, so part of the flying chips will fall back onto the grinding surface of the stainless steel casting or remain free inside the outer shell 200. In order to clean these rust chips, an internal processing component 500 is also provided to process the rust chips inside the outer shell 200.

[0068] Combination Fig.13 - Fig.15 As shown, preferably, the internal processing assembly 500 includes a closed cover 530, an inclined suction fan 540 is provided at the lower part of the closed cover 530, and an air intake pipe 570 is fixedly provided at the outer periphery of the closed cover 530 and at a position opposite to the closed cover 530, and when the suction fan 540 rotates, the flying chips around the inner periphery of the housing 200 can be sucked into the closed cover 530 through the air intake pipe 570. Therefore, this solution can prevent the accumulation of rust chips on the polishing surface of the stainless steel casting, thereby affecting the polishing.

[0069] In addition, in order to lock the position of the closing cover 530, a fixing rod 580 is also provided here, and the lower end of the fixing rod 580 is fixed to the upper end of the closing cover 530, preferably fixed to the center of the closing cover 530, and the upper end of the fixing rod 580 is fixed to the upper end of the outer shell 200 after passing through the main drive shaft 490, thereby achieving the purpose of fixing the position of the closing cover 530 by the fixing rod 580 and ensuring the stability of the closing cover 530.

[0070] like Fig.15 It should be noted that, in order to cooperate with the passage of the fixing rod 580, the main drive shaft 490 is made into a hollow structure here, and the fixing rod 580 can be located in the hollow structure and has no contact with the hollow inner wall of the main drive shaft 490, thereby reducing the wear of the main drive shaft 490 and the fixing rod 580; since the fixing rod 580 needs to pass through the upper end of the main drive shaft 490, the above-mentioned drive structure 410 preferably includes a motor 411 installed on the upper end of the housing 200, a driving gear 413 fixed to the power output end of the motor 411, and a driven gear 412 fixed to the upper end of the main drive shaft 490, and the driving gear 413 is meshed with the driven gear 412.

[0071] Furthermore, in order to collect the rust chips in the closed cover 530, a recessed area 532 is provided here. The recessed area 532 is located in the middle part below the closed cover 530. The recessed area 532 is used to receive the flying chips transported by the suction fan 540. A head 533 is provided at the lower end of the recessed area 532. The rust chips in the recessed area 532 can be discharged by opening the head 533.

[0072] Optionally, the sealing head 533 here is a threaded cover threadedly connected to the lower end of the recessed area 532 or a sealing plug inserted into the lower end of the recessed area 532.

[0073] Preferably, the space within the closed cover 530 should be as small as possible while being able to accommodate the suction fan 540, thereby ensuring that the suction fan 540 can send the sucked rust chips into the recessed area 532, and it is best to set the path through which the airflow and rust chips pass to be streamlined, thereby reducing the movement resistance of the airflow and rust chips, and ensuring that the rust chips can enter the recessed area 532.

[0074] Combination Figure 11-Figure 15 As shown, in order to realize the active rotation of the suction fan 540, a accommodating hole 531 is also provided, and the accommodating hole 531 is opened at a position opposite to the suction fan 540 on the upper wall of the closing cover 530; an internal gear 550 is accommodated in the accommodating hole 531, and a universal joint 560 is provided between the central axis of the internal gear 550 and the central axis of the suction fan 540, so that the rotation of the suction fan 540 is driven by the rotation of the internal gear 550 to realize the suction of rust chips; and in order to realize the rotation of the internal gear 550, an inner gear ring 510 and a connecting rod 520 for fixing the inner gear ring 510 to the umbrella gear ring 450 are also provided here, so that the inner gear ring 510 can rotate synchronously with the umbrella gear ring 450 when rotating under the umbrella gear ring 450, and the inner gear ring 510 is located at the periphery of the closing cover 530, and the inner gear ring 510 is meshed with any inner gear 550.

[0075] In this embodiment, the rotation of the umbrella-shaped gear ring 450 drives the inner gear ring 510 to rotate. When the inner gear ring 510 rotates, it can drive all the inner gears 550 to rotate, thereby achieving synchronous rotation of multiple suction fans 540.

[0076] Combination Fig.10 and Fig.16 As shown, since the flying chips of the grinding head 800 are intercepted by the outer shell 200 during grinding, some of the flying chips fall vertically after being intercepted. In order to deal with these vertically falling rust chips, the present embodiment further provides an external processing component 600, which includes a chimeric ring 610 and a slope ring 630 integrally formed on the inner wall of the chimeric ring 610. The chimeric ring 610 is engaged with the inner wall of the lower end of the outer shell 200. The slope of the slope ring 630 is inclined downward, and the top of the slope of the slope ring 630 is lower than the height at which the flying chips hit the inner wall of the outer shell 200 when the grinding head 800 is grinding. Therefore, the slope ring 630 can receive the flying chips that fall after hitting the inner wall of the outer shell 200, thereby preventing the rust chips from falling back onto the grinding surface of the stainless steel casting.

[0077] like Fig.16 In order to prevent the rust chips that fall on the slope ring 630 from returning to the polished surface of the stainless steel casting along the slope downward, a blocking protrusion 620 is provided. The blocking protrusion 620 is arranged in a ring shape at equal or unequal distances on the upper surface of the slope ring 630 to prevent the flying chips from escaping from the slope ring 630 downward.

[0078] In addition, the engaging ring 610 here is preferably a metal steel sheet structure with a certain toughness, so that it can be easily installed into and removed from the lower end of the shell 200, and the internal rust can be easily cleaned after removal.

[0079] When in use, the main drive shaft 490 is driven to rotate by the driving structure, and when it rotates, it can drive the umbrella gear ring 450 to rotate, and then realize the rotation of each driven umbrella wheel 480. When the driven umbrella wheel 480 rotates, the grinding head 800 can be rotated by the action of the rotating shaft 820, so that the grinding head 800 can perform a grinding operation to remove rust on the surface of the stainless steel casting. At the same time, these rust chips are splashed due to the centrifugal force. Since they are tilted and splashed, the housing 200 can block the splashed rust chips, and the blocked larger rust chips are The rust chips fall onto the slope ring 630 due to their own weight, and the smaller free rust chips and the rust chips on the surface of the stainless steel casting are absorbed by the internal processing component 500. The working principle of the internal processing component 500 is as follows: the umbrella-shaped gear ring 450 drives the inner gear ring 510 to rotate through the connecting rod. When the inner gear ring 510 rotates, it can drive all the inner gears 550 to rotate, and then realize the synchronous rotation of multiple suction fans 540. When the suction fan 540 rotates, it can suck in the free rust chips and the rust chips on the surface of the stainless steel casting through the air intake pipe 540 and store them in the recessed area.
