The work disk is fixedly installed on the workbench. The two mounting plates are symmetrically formed with the center of the work disk as the center and vertically fixedly installed on the work disk. The lower grinding component penetrates and is arranged in the workbench and the work disk and the three are coaxial. The upper grinding component is vertically movably arranged between the two mounting plates, and the upper grinding component faces the lower grinding component. It also includes a first bevel gear and a lateral grinding component.

[0004] The above device has certain deficiencies when performing plate grinding operations. The above device adopts a single grinding structure, so that it can only complete the single-sided grinding treatment of materials during use, and cannot perform the switching operation between single-sided or double-sided grinding, reducing its flexibility during use; and when the grinding device is in use, the debris generated during grinding will adhere to the surface of the grinding structure, and the cleaning operation of the grinding structure cannot be completed synchronously, thereby reducing its use effect; and different specifications of metal plates are prone to tilting during transportation, affecting the contact effect between the material and the grinding structure, and it does not have a material deviation correction structure. Summary of the Invention

[0005] The purpose of the present invention is to provide a grinding device for the surface treatment of bearing shell plates, which can solve the existing problems.

[0006] The problems solved by the present invention are:

[0007] 1. The above device is set with a single grinding structure, so that it can only complete the single-sided grinding treatment of materials during use, and cannot perform the switching operation between single-sided or double-sided grinding, reducing its flexibility during use. Moreover, when the grinding device is in use, the debris generated during grinding will adhere to the surface of the grinding structure, and the cleaning operation of the grinding structure cannot be completed synchronously, thus reducing its use effect. In addition, different specifications of metal plates are prone to tilting during transportation, affecting the contact effect between the material and the grinding structure, and it does not have a material deviation correction structure.

[0008] The object of the present invention can be achieved by the following technical solutions:

[0009] A grinding device for surface treatment of bearing shell plates, including a fixed base and a sealing cover. The sealing cover is fixedly installed on the upper outer surface of the fixed base. A second grinder and a first grinder are arranged inside the sealing cover. The second grinder is movably installed on one side of the first grinder. The first grinder includes a grinding belt and a dust collection cover. Several groups of driving rollers are arranged inside the grinding belt. The grinding belt is movably installed below the dust collection cover. The second grinder includes a base and a grinding wheel. The grinding wheel is movably installed at the middle position of the upper end of the base. A positioning roller rod for cooperating with the grinding belt is arranged inside the dust collection cover. The first grinder and the sealing cover are driven by a lifting rod, and a deviation corrector is installed at the upper part of one end of the fixed base.

[0010] As a further technical solution of the present invention, an elastic sleeve is arranged between the lifting rod and the dust collection cover. A fixing rod for docking with the dust collection cover is movably installed inside the elastic sleeve, and a spring is installed between the lifting rod and the fixing rod inside the elastic sleeve. By using the setting of the elastic sleeve in cooperation with the spring, an elastic connection structure is formed between the dust collection cover and the lifting rod. When the lifting rod drives the dust collection cover to move downward, the grinding belt installed in the dust collection cover elastically contacts the surface of the metal plate, improving the contact effect between the grinding belt and the metal plate. The grinding belt is independently driven by a motor to rotate, and the surface of the metal plate is ground by the grinding belt.

[0011] As a further technical solution of the present invention, a vacuum cleaner for cooperating with the dust collection cover is arranged at the upper end of the sealing cover. A suction pipe is installed between the vacuum cleaner and the dust collection cover. When the lifting rod drives the dust collection cover to move downward, the dust collection cover covers the upper end of the metal plate, which can improve the negative pressure effect during the dust suction operation of the metal plate. By starting the vacuum cleaner, suction is generated in the dust collection cover through the suction pipe, and the metal debris is sucked and cleaned during the grinding operation of the grinding belt on the metal plate.

[0012] As a further technical solution of the present invention, second blowers are provided on both sides of the suction pipe at the upper end of the dust collection hood. The three positioning roller rods are distributed in an isosceles triangle. The grinding belt passes through the three positioning roller rods and is in a symmetrically inclined structure. When the vacuum cleaner is in use, first, due to the arrangement of the three positioning roller rods, when the grinding belt passes through the three positioning roller rods, the surface change of the grinding belt is completed. When the grinding belt passes through the middle positioning roller rod, the positioning roller rod makes the surface of the grinding belt arc-shaped. At this time, the metal powder adhered to the surface of the grinding belt is separated from its surface during the bending process of the grinding belt. The surface of the grinding belt is back blown by the second blower to complete the cleaning operation of the metal powder on the grinding belt. At this time, the metal powder is cleaned by negative pressure suction using the suction force of the suction pipe, so that the grinding belt always maintains a good grinding effect.

[0013] As a further technical solution of the present invention, a dust collection box is spliced and installed inside the vacuum cleaner. A first blower is provided below the dust collection box inside the vacuum cleaner. The lower end of the vacuum cleaner is connected to the suction pipe in a through manner. By starting the first blower inside the vacuum cleaner, suction is generated inside the dust collection hood, and when the grinding belt grinds the metal plate, the generated metal dust is cleaned.

[0014] As a further technical solution of the present invention, the base and the grinding wheel are driven by a lifting jack rod. Feeding frames are provided on both sides of the grinding wheel at the upper end of the base. Using the first grinder and the second grinder, single-sided or double-sided grinding operations on the metal plate can be completed. During single-sided grinding, the lifting jack rod drives the grinding wheel to move downward, so that the grinding wheel is separated from the lower surface of the metal plate, and only the grinding belt of the first grinder is used to grind the upper surface of the metal plate. During double-sided grinding, the lifting jack rod drives the grinding wheel to move upward. When the metal plate passes through the feeding frame, the grinding wheel contacts the lower surface of the metal plate, and the lower surface of the metal plate is ground by the grinding wheel.

[0015] As a further technical solution of the present invention, a lifting clamping seat is provided on the other side of the first grinder inside the sealing cover. Feeding rods are movably installed on the lower part of the lifting clamping seat and the inner side of the feeding frame. The feeding rods are driven by motors. When the metal plate contacts the feeding rods, the feeding rods can be used to drive the metal plate to move.

[0016] As a further technical solution of the present invention, two positioning clamping plates are movably installed inside the deviation corrector. The two positioning clamping plates are symmetrically arranged. One end of the two positioning clamping plates is inclined. One side of the positioning clamping plate is driven by a side push rod. The side push rod is an electric push rod. During the feeding and conveying process of the metal plate, the side push rod is used to drive the positioning clamping plate to move, so that the positioning clamping plate clamps on both sides of the metal plate, playing a guiding role in the conveying of the metal plate.

[0017] As a further technical solution of the present invention, a number of groups of guide wheels are movably installed on the outer surface of the side of the positioning card board, and a number of groups of ball shafts are movably installed on the outer surface of the bottom of the positioning card board. By setting the guide wheels, the friction between the positioning card board and the metal plate can be reduced, and the setting of the ball shafts can reduce the friction between the positioning card board and the conveyor belt, and at the same time, it can meet the displacement use of the positioning card board.

[0018] As a further technical solution of the present invention, a conveyor belt is movably installed on the upper part of one end of the fixed base, a feeding roller is movably installed on the upper part of the other end of the fixed base, and a control cabinet is installed at the front end of the fixed base. The conveyor belt is used to convey the metal plate into the interior of the sealing cover for grinding treatment, and the ground metal plate is transferred to the powder sprinkling machine through the feeding roller for subsequent powder sprinkling operation.

[0019] The beneficial effects of the present invention:

[0020] 1. By setting the first grinding device and the second grinding device, when the grinding device for surface treatment of the bearing bush plate is used, it has a double-sided grinding structure, which can be flexibly applied to the single-sided or double-sided grinding of materials, and improves its flexibility in use;

[0021] During operation, the first grinding device uses the setting of the elastic sleeve and the spring, so that there is an elastic connection structure between the dust collection cover and the lifting rod. When the lifting rod drives the dust collection cover to move down, the grinding belt installed in the dust collection cover is elastically contacted with the surface of the metal plate, improving the contact effect between the grinding belt and the metal plate. The motor independently drives the grinding belt to rotate, and the surface of the metal plate is ground by the grinding belt. During single-sided grinding, the lifting ejector rod drives the grinding wheel to move down, so that the grinding wheel is separated from the lower surface of the metal plate, and only the grinding belt of the first grinding device is used to grind the upper surface of the metal plate. During double-sided grinding, the lifting ejector rod drives the grinding wheel to move up. When the metal plate passes through the feeding frame, the grinding wheel contacts the lower surface of the metal plate, and the lower surface of the metal plate is ground by the grinding wheel. When the metal plate passes through the lower part of the first grinding device, the lower surface of the metal plate can be ground by the grinding wheel of the second grinding device, thereby increasing the surface roughness of the metal plate, grinding the surface of the plate to enhance the adhesion force, and improving the bonding effect during the subsequent powder spreading and sintering operations of the metal plate.

[0022] 2. By setting the dust collection cover and the second fan, when the grinding device for surface treatment of the bearing bush plate is used, it has a negative pressure dust suction structure, which can synchronously clean the metal debris generated during the grinding of the metal plate, and at the same time synchronously clean the metal dust adhered to the surface of the grinding structure, so that it maintains a good grinding effect;

[0023] When the vacuum cleaner is in use, first, by setting three groups of positioning rollers, when the grinding belt passes through the three groups of positioning rollers, the surface change of the grinding belt is completed. When the grinding belt passes through the middle positioning roller, the positioning roller makes the surface of the grinding belt arc-shaped. At this time, the metal powder adhered to the surface of the grinding belt separates from its surface during the bending process of the grinding belt. The surface of the grinding belt is back-blown by the second blower to complete the cleaning operation of the metal powder on the grinding belt. At this time, the metal powder is cleaned by negative pressure suction using the suction force of the suction pipe. By starting the first blower in the vacuum cleaner, suction is generated inside the dust collection hood. When the grinding belt grinds the metal plate, the metal dust generated is cleaned, so that the grinding belt always maintains a good grinding effect.

[0024] 3. By setting a deviation rectifier, when the grinding device for surface treatment of bearing shell plates is in use, it can be flexibly applied to metal plates of different specifications, avoiding tilting during the grinding operation and improving its grinding effect.

[0025] During operation, during the feeding and conveying process of the metal plate, the side push rod is used to drive the positioning clamping plate to move, so that the positioning clamping plate is stuck on both sides of the metal plate, playing a guiding role in the conveying of the metal plate. By adjusting the positions of the two groups of positioning clamping plates, it can be applied to metal plates of different widths. One end of the positioning clamping plate is an inclined structure. When the metal plate contacts one end of the positioning clamping plate, the positioning clamping plate plays a guiding role for the metal plate, thereby guiding the metal plate between the two groups of positioning clamping plates. By setting guide wheels, the friction between the positioning clamping plate and the metal plate can be reduced, and the setting of ball shafts can reduce the friction between the positioning clamping plate and the conveyor belt, and at the same time can meet the displacement use of the positioning clamping plate to complete the deviation rectification operation of the metal plate.

[0036] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0037] As Figures 1-8 shown, a grinding device for surface treatment of a bearing shell plate includes a fixed base 1 and a sealing cover 4. The sealing cover 4 is fixedly installed on the upper outer surface of the fixed base 1. A second grinder 8 and a first grinder 9 are provided inside the sealing cover 4. The second grinder 8 is movably installed on one side of the first grinder 9. The first grinder 9 includes a grinding belt 10 and a dust collection cover 11. A plurality of groups of driving rollers 25 are provided inside the grinding belt 10. The grinding belt 10 is movably installed below the dust collection cover 11. The second grinder 8 includes a base 20 and a grinding wheel 22. The grinding wheel 22 is movably installed at the middle upper position of the base 20. A positioning roller rod 23 for cooperating with the grinding belt 10 is provided inside the dust collection cover 11. The first grinder 9 and the sealing cover 4 are driven by a lifting rod 14. A deviation rectifier 6 is installed on the upper part of one end of the fixed base 1.

[0038] To improve the grinding effect of the material, as Figure 2As shown in the figure, an elastic sleeve 13 is provided between the lifting rod 14 and the dust collection hood 11. A fixing rod 26 for docking with the dust collection hood 11 is movably installed inside the elastic sleeve 13, and a spring 31 is installed between the lifting rod 14 and the fixing rod 26 inside the elastic sleeve 13. With the arrangement of the elastic sleeve 13 and the spring 31, an elastic connection structure is formed between the dust collection hood 11 and the lifting rod 14. When the lifting rod 14 drives the dust collection hood 11 to move downward, the grinding belt 10 installed in the dust collection hood 11 elastically contacts the surface of the metal plate 32, improving the contact effect between the grinding belt 10 and the metal plate 32. The motor independently drives the grinding belt 10 to rotate, and the surface of the metal plate 32 is polished by the grinding belt 10.

[0039] To solve the dust problem during material grinding, as Figure 5 shown, a dust collector 5 for cooperating with the dust collection hood 11 is provided at the upper end of the sealing cover 4. A suction pipe 17 is installed between the dust collector 5 and the dust collection hood 11. When the lifting rod 14 drives the dust collection hood 11 to move downward, the dust collection hood 11 covers the upper end of the metal plate 32, which can improve the negative pressure effect during the dust suction operation of the metal plate 32. By starting the dust collector 5, suction is generated in the dust collection hood 11 through the suction pipe 17. During the grinding operation of the grinding belt 10 on the metal plate 32, the metal chips are sucked and cleaned.

[0040] Since the surface of the grinding belt 10 is uneven, during the grinding process, metal powder is easily adsorbed on the surface of the grinding belt 10, and it is very difficult to clean it completely by relying solely on the negative pressure adsorption method;

[0041] As Figure 5 shown, second blowers 24 are provided on both sides of the suction pipe 17 at the upper end of the dust collection hood 11. The three positioning roller rods 23 are distributed in an isosceles triangle. The grinding belt 10 passes through the three positioning roller rods 23 and is in a symmetrically inclined structure. When the dust collector 5 is in use, first, with the arrangement of the three positioning roller rods 23, when the grinding belt 10 passes through the three positioning roller rods 23, the surface change of the grinding belt 10 is completed. When the grinding belt 10 passes through the middle positioning roller rod 23, the positioning roller rod 23 makes the surface of the grinding belt 10 arc-shaped. At this time, the metal powder adhered to the surface of the grinding belt 10 separates from its surface during the bending process of the grinding belt 10. The second blowers 24 are used to blow the surface of the grinding belt 10, completing the cleaning operation of the metal powder on the grinding belt 10. At this time, the suction of the suction pipe 17 is used to perform negative pressure dust suction cleaning on the metal powder, so that the grinding belt 10 always maintains a good grinding effect.

[0042] Inside the vacuum cleaner 5, a dust collection box 15 is spliced and installed. Below the dust collection box 15 inside the vacuum cleaner 5, a first blower 16 is provided. The lower end of the vacuum cleaner 5 is connected to a suction pipe 17 in a through manner. By starting the first blower 16 inside the vacuum cleaner 5, suction is generated inside the dust collection hood 11, and when the grinding belt 10 grinds the metal plate 32, the generated metal dust is cleaned up.

[0043] The base 20 and the grinding wheel 22 are driven by a lifting jack rod 21. On both sides of the grinding wheel 22 at the upper end of the base 20, a feeding rack 19 is provided. Using the first grinder 9 and the second grinder 8, single-sided or double-sided grinding operations on the metal plate 32 can be completed. During single-sided grinding, the lifting jack rod 21 drives the grinding wheel 22 to move downward, so that the grinding wheel 22 is separated from the lower surface of the metal plate 32, and only the grinding belt 10 of the first grinder 9 is used to grind the upper surface of the metal plate 32. During double-sided grinding, the lifting jack rod 21 drives the grinding wheel 22 to move upward. When the metal plate 32 passes through the feeding rack 19, the grinding wheel 22 is in contact with the lower surface of the metal plate 32, and the lower surface of the metal plate 32 is ground by the grinding wheel 22.

[0044] Inside the sealing cover 4, on the other side of the first grinder 9, a lifting clamping seat 12 is provided. Feeding rods 18 are movably installed on the lower part of the lifting clamping seat 12 and the inner side of the feeding rack 19. The feeding rods 18 are driven by motors. When the metal plate 32 comes into contact with the feeding rods 18, the feeding rods 18 can be used to drive the metal plate 32 to move.

[0045] As Figure 6 shown, two groups of positioning clamping plates 27 are movably installed inside the alignment device 6. The two groups of positioning clamping plates 27 are symmetrically arranged. One end of the two groups of positioning clamping plates 27 is inclined. One side of the positioning clamping plate 27 is driven by a side push rod 30. The side push rod 30 is an electric push rod. During the feeding and conveying process of the metal plate 32, the side push rod 30 is used to drive the positioning clamping plate 27 to move, so that the positioning clamping plate 27 is clamped on both sides of the metal plate 32, playing a guiding role in the conveying of the metal plate 32.

[0046] A number of guide wheels 29 are movably installed on the outer surface of the side of the positioning clamping plate 27, and a number of ball shafts 28 are movably installed on the outer surface of the bottom of the positioning clamping plate 27. By providing the guide wheels 29, the friction between the positioning clamping plate 27 and the metal plate 32 can be reduced, and the setting of the ball shafts 28 can reduce the friction between the positioning clamping plate 27 and the conveyor belt 7, and at the same time can meet the displacement use of the positioning clamping plate 27.

[0047] At the upper part of one end of the fixed base 1, a conveyor belt 7 is movably installed. At the upper part of the other end of the fixed base 1, a feeding roller 3 is movably installed. And a control cabinet 2 is installed at the front end of the fixed base 1. The metal plate 32 is conveyed into the interior of the sealing cover 4 by the conveyor belt 7 for grinding treatment. After grinding, the metal plate 32 is transferred to the powder spraying machine by the feeding roller 3 for subsequent powder spraying operation.

[0048] During use, by setting the first grinding device 9 and the second grinding device 8, when the grinding device for surface treatment of the bearing bush plate is in use, it has a double-sided grinding structure, which can be flexibly applied to the single-sided or double-sided grinding of materials, improving its flexibility during use.

[0049] During operation, the first grinding device 9 uses the elastic sleeve 13 and the spring 31 to make an elastic connection structure between the dust collection cover 11 and the lifting rod 14. When the lifting rod 14 drives the dust collection cover 11 to move downward, the grinding belt 10 installed in the dust collection cover 11 is elastically in contact with the surface of the metal plate 32, improving the contact effect between the grinding belt 10 and the metal plate 32. The motor independently drives the grinding belt 10 to rotate, and the surface of the metal plate 32 is ground by the grinding belt 10. During single-sided grinding, the lifting jack rod 21 drives the grinding wheel 22 to move downward, separating the grinding wheel 22 from the lower surface of the metal plate 32, and only the grinding belt 10 of the first grinding device 9 is used to grind the upper surface of the metal plate 32. During double-sided grinding, the lifting jack rod 21 drives the grinding wheel 22 to move upward. When the metal plate 32 passes through the feeding frame 19, the grinding wheel 22 is in contact with the lower surface of the metal plate 32, and the lower surface of the metal plate 32 is ground by the grinding wheel 22. When the metal plate 32 passes through the lower part of the first grinding device 9, the grinding wheel 22 of the second grinding device 8 can grind the lower surface of the metal plate 32, thereby increasing the surface roughness of the metal plate 32, grinding the surface of the plate to enhance the adhesion force, and improving the bonding effect during the subsequent powder spreading and sintering operations of the metal plate 32.

[0050] By setting the dust collection cover 11 and the second fan 24, when the grinding device for surface treatment of the bearing bush plate is in use, it has a negative pressure dust suction structure, which can synchronously clean the metal debris generated during the grinding of the metal plate 32, and at the same time synchronously clean the metal dust adhered to the surface of the grinding structure, keeping it in good grinding effect.

[0051] When the vacuum cleaner 5 is in use, first, by means of the setting of the three groups of positioning rollers 23, when the grinding belt 10 passes through the three groups of positioning rollers 23, the surface change of the grinding belt 10 is completed. When the grinding belt 10 passes through the middle positioning roller 23, the positioning roller 23 makes the surface of the grinding belt 10 arc-shaped. At this time, the metal powder adhered to the surface of the grinding belt 10 is separated from its surface during the bending process of the grinding belt 10. The second blower 24 is used to blow the surface of the grinding belt 10 in the opposite direction to complete the cleaning operation of the metal powder on the grinding belt 10. At this time, the suction force of the suction pipe 17 is used to clean the metal powder under negative pressure. By starting the first blower 16 in the vacuum cleaner 5, suction is generated inside the dust collection hood 11. When the grinding belt 10 grinds the metal plate 32, the metal dust generated is cleaned, so that the grinding belt 10 always maintains a good grinding effect;

[0052] By setting the deviation rectifier 6, when the grinding device for surface treatment of the bearing shell plate is in use, it can be flexibly adapted to metal plates 32 of different specifications, avoiding tilting during the grinding operation and improving its grinding effect;

[0053] During operation, during the feeding and conveying process of the metal plate 32, the side push rod 30 is used to drive the positioning clamping plate 27 to move, so that the positioning clamping plate 27 is stuck on both sides of the metal plate 32, playing a guiding role in the conveying of the metal plate 32. By adjusting the positions of the two groups of positioning clamping plates 27, it can be adapted to metal plates 32 of different widths. One end of the positioning clamping plate 27 is of an inclined structure. When the metal plate 32 contacts one end of the positioning clamping plate 27, the positioning clamping plate 27 plays a guiding role for the metal plate 32, thereby guiding the metal plate 32 between the two groups of positioning clamping plates 27. The setting of the guide wheel 29 can reduce the friction between the positioning clamping plate 27 and the metal plate 32, and the setting of the ball shaft 28 can reduce the friction between the positioning clamping plate 27 and the conveyor belt 7, and at the same time can meet the displacement use of the positioning clamping plate 27 to complete the deviation rectification operation of the metal plate 32.

Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the equivalent embodiments with equivalent changes within the scope of the technical solution of the present invention.
