Description

Technical Field

[0001] The present invention relates to the technical field of casting grinding, and particularly relates to an internal and external synchronous grinding mechanism for square castings. Background Art

[0002] A "casting" refers to a metal part or product manufactured through a casting process. Casting is a process in which a metal material is heated to a liquid state and then poured into a pre-made mold. After it cools and solidifies, a metal product with a certain shape and properties is formed. For example, a casting bearing seat. The products processed by this casting method need to be ground. In particular, there are defects such as burrs, sand holes, and flash at the edges and corners of the products, laying a foundation for subsequent fine grinding. For general-shaped castings, they are directly ground, and an internal and external synchronous grinding mechanism can be used for grinding;

[0003] However, since some bearing seats are square, ordinary internal and external grinding mechanisms cannot grind castings with an inner circle and an outer square at the same time. In addition, when grinding burrs and flash on the castings, debris splashes, posing a safety hazard. If not dealt with in time, the debris is likely to accumulate in the grinding mechanism, affecting normal operation. Therefore, the present application provides an internal and external synchronous grinding mechanism for square castings to meet the requirements. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an internal and external synchronous grinding mechanism for square castings to solve the problems that the existing internal and external grinding mechanisms are not applicable to square shaft seats, and debris splashing during grinding affects safety and the normal operation of the grinding mechanism.

[0005] To solve the above technical problems, the present invention provides the following technical solutions:

[0006] An internal and external synchronous grinding mechanism for square castings, including a frame and a conveyor belt, as well as a first displacement mechanism and a second displacement mechanism provided on the frame. A square shaft seat is placed on the conveyor belt, and when the conveyor belt operates, it conveys the square shaft seat. The square shaft seat includes a square base and an annular protrusion, and four through holes are provided on the square base; it further includes a first grinding component and a second grinding component. The first displacement mechanism is used to drive the first grinding component, and the second displacement mechanism is used to drive the second grinding component. The first grinding component is located on the side of the conveyor belt, and the second grinding component is located above the conveyor belt; the first grinding component includes a first driving member for grinding the outer wall of the square shaft seat, and the second grinding component includes a grinding head for grinding the inner wall of the square shaft seat.

[0007] Optionally, the first grinding assembly further includes guide plates disposed on both sides of the first driving member. The two guide plates are inclined outwardly with the first driving member as the center, and there are at least two sets of the first driving members. The first driving member further includes a grinding belt, and the grinding belt is located between the two guide plates.

[0008] Optionally, the second grinding assembly includes a mounting seat fixed on the second displacement mechanism. A second driving member is fixed in the mounting seat, and the grinding head is mounted at the output end of the second driving member.

[0009] Optionally, a fixing ring body is fixedly connected to the top end of the grinding head. A hollow area is formed between the fixing ring body and the grinding head. A first grinding layer and a second grinding layer are respectively fixedly connected to the inner wall of the fixing ring body and the outer wall of the grinding head.

[0010] Optionally, a fixing shell is further fixed on the mounting seat. A fixing tube is rotatably connected in the fixing shell. The bottom end of the fixing tube is fixedly connected with a fixing plate, and the top end of the fixing tube is fixedly connected with a gear. A steering driving mechanism is further arranged in the fixing shell, and the steering driving mechanism is in transmission cooperation with the gear; four corners of the fixing plate are each slidably connected with a positioning tube matching the size of the through hole. The bottom end of the positioning tube is of a conical structure, and the positioning tube includes an integrally formed first extension tube and a second extension tube. A protective shell with the same number as the positioning tubes is fixedly connected to the fixing plate. A through groove is formed on one side of the protective shell. The top end of the positioning tube is fixedly connected with an outer tube, and the outer tube slides in the through groove.

[0011] Optionally, a dust suction mechanism is further included. The top end of the positioning tube is fixedly connected with an outer tube. A detachable connecting tube is installed on the outer tube, and the connecting tube is connected to the dust suction port of the dust suction mechanism. A plurality of ash holes are formed on both the positioning tube and the first extension tube.

[0012] Optionally, a secondary tube with the same number as the positioning tubes is slidably connected to the fixing ring body. The bottom end of the secondary tube is located in the hollow area and is fixedly connected with an annular plate. A third grinding layer is fixed on the outer wall of the annular plate, and the top end of the secondary tube is fixed to the positioning tube.

[0013] Optionally, a protective sleeve is fixedly connected to the peripheral side wall of the fixing plate, and all four positioning tubes are located inside the protective sleeve. The bottom end of the protective sleeve is fixedly connected with a soft edge. Two sets of first notches and two sets of second notches are formed on the peripheral side wall of the protective sleeve. Among them, the two sets of first notches are formed on the opposite side walls of the protective sleeve, and the two sets of second notches are formed on the other opposite side walls of the protective sleeve. Four support plates are fixedly connected inside the protective sleeve, and the four positioning tubes are respectively inserted into the four support plates and fixed. The first notch matches the size of the first driving member, and the second notch matches the size of the guide plate.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects:

[0015] In the above solution, by setting the first grinding assembly and the second grinding assembly, the outer wall and the inner wall of the square shaft seat can be ground. Through the cooperation of the above structures, the synchronous grinding of the inside and outside of the square shaft seat is realized, thereby simplifying the processing flow and improving the production efficiency.

[0016] By setting the guide plate, the guide plates on the two groups of first driving parts jointly squeeze the square shaft seat, and the position of the square casting can be adjusted, thereby preventing the problem that the grinding work is not facilitated due to the deviation of the parking position of the square shaft seat; by setting four positioning pipes, the square base can be fixed to prevent the position of the square shaft seat from changing during the grinding process, which further facilitates the grinding process; and the guide plate in the above structure adjusts the position of the square shaft seat through guiding, which is beneficial to the positioning pipe to be smoothly inserted into the through hole.

[0017] By setting the dust suction mechanism and the connecting pipe, and opening ash holes on the four positioning pipes, the debris and dust generated by grinding are sucked into the connecting pipe through the ash holes and finally sent to the dust suction mechanism. And the four positioning pipes are evenly arranged around the square shaft seat, which is beneficial to improving the dust suction uniformity.

[0018] By setting the auxiliary pipe, the debris and dust generated by grinding in the hollow area can be conveyed into the positioning pipe through the auxiliary pipe and finally enter the dust suction mechanism. By setting the protective sleeve, on the one hand, the elastic protective sleeve can better fit the surface of the conveyor belt and the surface of the square shaft seat through deformation, improving the protective ability of the protective sleeve. On the other hand, when the positioning pipe is pulled out of the through hole, the deformed protective sleeve is reset, which is beneficial to driving the positioning pipe to be reset.

[0038] As shown in the figure, in order to clearly implement the structure of the embodiments of the present invention, specific structures and devices are marked in the figure. However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device, and environment. Those of ordinary skill in the art can adjust or modify these devices and environments according to specific needs. Detailed implementation manners

[0039] The following describes in detail a square casting internal and external synchronous grinding mechanism provided by the present invention with reference to the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative methods for implementation; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0040] It should be pointed out that in the specification, references to "an embodiment", "embodiments", "exemplary embodiments", "some embodiments", etc. indicate that the described embodiments may include specific features, structures, or characteristics, but not necessarily every embodiment includes such specific features, structures, or characteristics. Additionally, when combining embodiments to describe specific features, structures, or characteristics, implementing such features, structures, or characteristics in combination with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the relevant art.

[0041] As Figures 1 to 16 shown, an embodiment of the present invention provides a square casting internal and external synchronous grinding mechanism, including a frame 1 and a conveyor belt 2, as well as a first displacement mechanism 3 and a second displacement mechanism 4 provided on the frame 1. A square shaft seat 9 is placed on the conveyor belt 2, and the conveyor belt 2 conveys the square shaft seat 9 during operation. The square shaft seat 9 includes a square base 10 and an annular protrusion 11, and four through holes 12 are provided on the square base 10; it further includes a first grinding assembly and a second grinding assembly. The first displacement mechanism 3 is used to drive the first grinding assembly, and the second displacement mechanism 4 is used to drive the second grinding assembly. The first grinding assembly is located on the side of the conveyor belt 2, and the second grinding assembly is located above the conveyor belt 2; the first grinding assembly includes a first driving member 5 for grinding the outer wall of the square shaft seat 9, and the second grinding assembly includes a grinding head 15 for grinding the inner wall of the square shaft seat 9.

[0042] As Figure 6 、 Figure 11 and Figure 12As shown in the figure, the first grinding assembly further includes guide plates 6 disposed on both sides of the first driving member 5. The two guide plates 6 are inclined outwardly with the first driving member 5 as the center, and there are at least two sets of the first driving members 5. The first driving member 5 further includes a grinding belt 7, and the grinding belt 7 is between the two guide plates 6. Among them, the first driving member 5 and the grinding belt 7 are prior art and will not be elaborated in detail. By providing two first driving members 5, and the two first driving members 5 are respectively disposed on both sides of the square shaft seat 9. When the square shaft seat 5 is conveyed between the two first driving members 5 by the conveyor belt 2, and the two first driving members 5 are inclined, the grinding belt 7 on the first driving member 5 is aligned with the right-angle side of the square shaft seat 9. When the first driving member 5 is started, the grinding belt 7 grinds the burrs on the right-angle side of the casting. By providing guide plates 6 on both sides of the first driving member, since the two guide plates 6 are both inclined outwardly, when the square shaft seat 9 stops being conveyed on the conveyor belt 2, the first displacement mechanism 3 drives the two first driving members 5 to move towards the square shaft seat 9, and the guide plates 6 in the expanded state contact the square shaft seat 9. The guide plates 6 on the two sets of first driving members 5 jointly squeeze the square shaft seat 9, thereby adjusting its position, and further preventing the problem that the grinding work is not facilitated due to the offset parking position of the square shaft seat 9. The above structure can guide the offset square shaft seat 9 to be located between the two grinding belts 7.

[0043] As Figure 6 and Figure 9 shown in the figure, the second grinding assembly includes a mounting seat 13 fixed on the second displacement mechanism 4. A second driving member 14 is fixed inside the mounting seat 13. A grinding head 15 is installed at the output end of the second driving member 14. A fixing ring body 16 is fixedly connected to the top end of the grinding head 15. A hollow area 17 is formed between the fixing ring body 16 and the grinding head 15. A first grinding layer 18 and a second grinding layer 19 are respectively fixedly connected to the inner wall of the fixing ring body 16 and the outer wall of the grinding head 15. The grinding layer is a prior art product and is selected according to the grinding requirements. Among them, the cross-section of the fixing ring body 16 is a right-angle structure. By providing the fixing ring body 16, during grinding, the grinding head 15 is located inside the annular protrusion 11 in the square shaft seat 9, so that the second grinding layer 19 grinds the inner wall of the annular protrusion 11, and the first grinding layer 18 grinds the outer wall of the annular protrusion 11. Through the cooperation of the above structure, the synchronous internal and external grinding of the square shaft seat 9 is realized, thereby simplifying the processing flow and improving the production efficiency.

[0044] As Figures 2 to 8As shown, a fixed shell 26 is also fixed on the mounting base 13. A fixed pipe 24 is rotatably connected inside the fixed shell 26. The bottom end of the fixed pipe 24 is fixedly connected with a fixed plate 23, and the top end of the fixed pipe 24 is fixedly connected with a gear 25. A steering drive mechanism 27 is also arranged inside the fixed shell 26. The steering drive mechanism 27 is in transmission cooperation with the gear 25. The steering drive mechanism 27 includes structures such as a motor, a drive gear, and a control system, etc. During operation, the motor drives the drive gear to mesh with the gear 25 on the fixed pipe 24 for transmission. The above mechanism is prior art, so no detailed description will be given here; four corners of the fixed plate 23 are all slidably connected with positioning pipes 29 that are matched with the through holes 12 in size. The bottom end of the positioning pipe 29 is of a conical structure, and the positioning pipe 29 includes an integrally formed first extension pipe 36 and a second extension pipe 37; by arranging four positioning pipes 29, during operation, the second displacement mechanism 4 drives the steering drive mechanism 27 and the four positioning pipes 29 to move downward. When the four positioning pipes 29 are inserted into the through holes 12 on the square base 10, the four positioning pipes 29 can fix the square base 10 to prevent the position of the square shaft seat 9 from changing during the grinding process, thereby further facilitating the grinding process; in addition, the guide plate 6 in the above structure guides and positions the square shaft seat 9, which is beneficial for the positioning pipes 29 to be smoothly inserted into the through holes 12; after the two sides of the square shaft seat 9 are ground, first, the first displacement mechanism 3 drives the first driving member 5 to reset, and then the steering drive mechanism 27 is used to adjust the rotation angle of the square shaft seat so that the unground area on the square shaft seat 9 is aligned with the grinding belt 7. Then, the first displacement mechanism 3 drives the first driving member 5 to move so that the grinding belt 7 contacts the square shaft seat 9, and grinding can start. The realization of the above actions is prior art, and no detailed description will be given here.

[0045] As Figure 14 and Figure 15 shown, a protective shell 28 with the same number as the positioning pipes 29 is fixedly connected to the fixed plate 23. A through groove 31 is opened on one side of the protective shell 28. The top end of the positioning pipe 29 is fixedly connected with an outer pipe 32. The outer pipe 32 is slidably located in the through groove 31. By opening the through groove 31 on the protective shell 28, the function of the through groove 31 is to allow the outer pipe 32 to move.

[0046] It further includes a dust suction mechanism 8. The dust suction mechanism 8 is prior art and will not be described in detail here. The top end of the positioning pipe 29 is fixedly connected with an outer pipe 32. A detachable connecting pipe 42 is installed on the outer pipe 32. The connecting pipe 42 is connected to the dust suction port of the dust suction mechanism 8. A number of ash holes 30 are opened on both the positioning pipe 29 and the first extension pipe 36. By arranging the dust suction mechanism 8 and the connecting pipe 42, and opening the ash holes 30 on the four positioning pipes 29, the debris and dust generated during grinding are sucked into the connecting pipe 42 through the ash holes 30 and finally sent to the dust suction mechanism 8. Moreover, the four positioning pipes 29 are evenly arranged around the square shaft seat 9, which is beneficial to improving the dust suction uniformity.

[0047] As Figure 1, Figure 9 and Figure 10 As shown in Figure 10 and Figure 9 , the same number of auxiliary pipes 21 as the positioning pipes 29 are slidably connected to the fixed ring body 16. The bottom ends of the auxiliary pipes 21 are located in the hollow area 17 and are fixedly connected with an annular plate 20. The outer wall of the annular plate 20 is fixed with a third grinding layer 22. The top ends of the auxiliary pipes 21 are fixed to the positioning pipes 29. By providing the auxiliary pipes 21 fixed to the positioning pipes 29 and the auxiliary pipes 21 being slidably connected to the fixed ring body 16, during grinding, the third grinding layer 22 contacts the top end of the annular protrusion 11, thereby grinding the top surface of the annular protrusion 11. At the same time, since the auxiliary pipes 21 are of a hollow structure and the hollow structure communicates with the hollow area 17, therefore, the debris and dust generated during grinding in the hollow area 17 can be conveyed into the positioning pipes 29 through the auxiliary pipes 21 and finally enter the dust collection mechanism 8.

[0048] As Figure 7 and Figures 13 to 16 shown, a protective sleeve 38 is fixedly connected to the peripheral side wall of the fixing plate 23, and all four positioning pipes 29 are located inside the protective sleeve 38. The bottom end of the protective sleeve 38 is fixedly connected with a soft edge 39. Two groups of first slots 40 and two groups of second slots 41 are provided on the peripheral side wall of the protective sleeve 38. Among them, the two groups of first slots 40 are provided on the opposite side walls of the protective sleeve 38, and the two groups of second slots 41 are provided on the other opposite side walls of the protective sleeve 38; four support plates 35 are fixedly connected inside the protective sleeve 38, and the four positioning pipes 29 are respectively inserted into the four support plates 35 and fixed. By providing the protective sleeve 38, the protective sleeve 38 is located around the four positioning pipes 29. When the positioning pipes 29 are fixed by being inserted into the through holes 12, the protective sleeve 38 covers the periphery of the square shaft seat 9 to form a protective structure. In this way, the dust and debris generated during grinding are blocked by the protective sleeve 38, preventing the problem of flying around and posing a safety hazard, and the problem that a large amount of volume debris falls on the conveyor belt 2 and affects the work; in addition, the debris and dust are concentrated inside the protective sleeve 38, which is beneficial for the dust collection mechanism 8 to collect.

[0049] As Figure 9 and Figure 13As shown, the protective sleeve 38 is made of an elastic material, such as rubber, and the positioning tube 29 is fixed through the support plate 35 and the protective sleeve 38. The top end of the positioning tube 29 is slidably connected to the fixing plate 23. The advantage of this setting is that when the positioning tube 29 is pressed down, the positioning tube 29 drives the protective sleeve 38 to move upward through the support plate 35, causing partial deformation of the elastic protective sleeve 38. On the one hand, the elastic protective sleeve 38 can better fit the surface of the conveyor belt 2 and the surface of the square shaft seat 9 through deformation, improving the protection ability of the protective sleeve 38. On the other hand, when the positioning tube 29 is pulled out from the through hole 12, the deformed protective sleeve 38 is reset, which is beneficial to driving the positioning tube 29 to be reset; moreover, when the positioning tube 29 is pushed up by extrusion, it will drive the auxiliary tube 21 to move up, and when the positioning tube 29 is reset, the auxiliary tube 21 is also reset accordingly. During this process, the annular plate 20 is driven to move in the hollow area 17 through the auxiliary tube 21, which helps to drive the debris and dust accumulated on the annular plate 20 during the dust collection process to fall off, and then facilitates the collection by the dust collection mechanism 8.

[0050] As Figure 16 shown, the first notch 40 and the first driving member 5 are dimensionally matched, and the second notch 41 and the guide plate 6 are dimensionally matched. By providing the first notch 40 and the second notch 41 on the circumferential side wall of the protective sleeve 38, the first notch 40 covers the first driving member 5, the second notch 41 covers the guide plate 6, and the soft edge 39 at the bottom of the protective sleeve 38 contacts the surface of the conveyor belt 2, reducing the circulation of the internal and external spaces of the protective sleeve 38, further facilitating the collection of debris and dust and reducing the splashing of debris.

[0051] The working principle of the technical solution provided by the present invention is as follows: During use, the square shaft seat 9 is placed on the conveyor belt 2, and the start and stop conditions of the conveyor belt 2 are set as required. This is prior art and will not be elaborated here.

[0052] When the square shaft seat 9 stops conveying on the conveyor belt 2, the first displacement mechanism 3 drives the two first driving members 5 to move towards the square shaft seat 9, and the guide plate 6 in an expanded state contacts the square shaft seat 9. The guide plates 6 on the two groups of first driving members 5 jointly squeeze the square shaft seat 9 to adjust its position.

[0053] During grinding, the grinding head 15 is located in the annular protrusion 11 in the square shaft seat 9, so that the second grinding layer 19 grinds the inner wall of the annular protrusion 11, and the first grinding layer 18 grinds the outer wall of the annular protrusion 11.

[0054] While grinding, the second displacement mechanism 4 drives the steering drive mechanism 27 and the four positioning tubes 29 to move downward. When the four positioning tubes 29 are inserted into the through holes 12 on the square base 10, the four positioning tubes 29 can fix the square base 10 to prevent the position of the square shaft seat 9 from changing during the grinding process, thus further facilitating the grinding process. In addition, in the above structure, the guide plate 6 guides and positions the square shaft seat 9, which is conducive to the smooth insertion of the positioning tubes 29 into the through holes 12.

[0055] After the grinding of both sides of the square shaft seat 9 is completed, first, the first displacement mechanism 3 drives the first driving member 5 to reset, and then the steering drive mechanism 27 adjusts the rotation angle of the square shaft seat so that the unground area on the square shaft seat 9 is aligned with the grinding belt 7. Then, the first displacement mechanism 3 drives the first driving member 5 to move so that the grinding belt 7 contacts the square shaft seat 9, and the grinding can continue.

[0056] When the positioning tubes 29 are fixed by being inserted into the through holes 12, the protective sleeve 38 covers the periphery of the square shaft seat 9 to form a protective structure. In this way, the dust and debris generated during grinding are blocked by the protective sleeve 38, preventing the problem of splashing everywhere and posing a safety hazard, as well as the problem that a large amount of volume debris falls on the conveyor belt 2 and affects the work. In addition, the debris and dust are concentrated in the protective sleeve 38, which is conducive to the collection by the dust suction mechanism 8.

[0057] The present invention covers any substitutions, modifications, equivalent methods, and solutions made within the essence and scope of the present invention. In order to enable the public to have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention. However, those skilled in the art can fully understand the present invention without these detailed descriptions. In addition, in order to avoid unnecessary confusion to the essence of the present invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0058] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
