Description

Technical Field

[0001] This invention relates to the field of large spherical tile grinding technology, and in particular to a multi-dimensional precision grinding device and grinding method for rotary kiln spherical tiles. Background Technology

[0002] Spherical bearing plates are key components in rotary kiln roller bearings. Bearings with spherical bearing plates utilize ball milling to achieve multi-dimensional adjustment of the roller shaft, compensating for issues such as longitudinal bending of the kiln shell during operation and insufficient precision during roller machining and installation, ensuring good contact between the roller shaft and the spherical bearing plate. With the increasing size and weight of rotary kilns, the spherical bearing plates need to be ground to ensure multi-dimensional flexible adjustment within the bearing base, guaranteeing uniform contact between the plate surface and the shaft diameter and reducing copper plate burn-out. Due to the large weight of the spherical bearing plate, grinding it with the bearing base is very difficult, requiring significant manual labor. The initial grinding amount (i.e., the position of the spherical bearing plate relative to the bearing base) is difficult to adjust, and the grinding dimension is singular. In practice, the two are often directly assembled according to machining precision, and grinding is performed by rotating along the axis of the rotating roller shaft, resulting in excessive initial grinding and potential damage to the spherical bearing plate. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a multi-dimensional precision grinding device and grinding method for rotary kiln spherical tiles, which can realize precise control of the grinding amount of spherical tiles and multi-dimensional grinding, improve grinding quality, avoid damage to spherical tiles, and reduce labor intensity.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0005] A multi-dimensional precision grinding device for rotary kiln spherical tiles includes a grinding power platform with two grinding power components spaced apart on the left and right sides. Both grinding power components are connected to a PLC controller. A support platform is provided on the front and rear sides of the grinding power platform. A bearing base can be placed in the space enclosed by the two support platforms and the grinding power platform. An adjustment component is installed on each support platform, and a support shaft is installed on the two adjustment components. A support frame is passed through the support shaft. The support frame is used to suspend the spherical tile. The center line of the spherical tile coincides with the axis of the support shaft. The support frame is a symmetrical structure centered on the axis of the support shaft. The support frame is connected to the grinding power components.

[0006] The spherical tile is suspended above the bearing base by a support frame. Under the control of a preset program, two grinding power components can pull the spherical tile to slide back and forth in the bearing base around the axis of the support shaft to achieve grinding.

[0007] As a preferred embodiment, the support frame includes a bushing that passes through the support shaft, a T-shaped plate that is horizontally symmetrically arranged on both sides of the bushing, a crossbeam plate that is provided on the two T-shaped plates, and two lifting shackles that are provided on the crossbeam plate. The lifting shackles are connected to the grinding power assembly on the same side. Each T-shaped plate has at least one bolt hole, and at least one bolt is engaged with the corresponding bolt hole for hanging the spherical tile.

[0008] As a preferred embodiment, both grinding power components include an electric drum fixed to the grinding power platform and a steel wire rope wound on the electric drum, the steel wire rope being connected to a lifting shackle.

[0009] As a preferred embodiment, the adjustment assembly includes a height adjustment unit mounted on the support platform and a spherical rotary support fixed on the height adjustment unit. Both ends of the support shaft are mounted on the spherical rotary support, and the installation position of the adjustment assembly on the support platform can be adjusted according to the grinding requirements.

[0010] As a preferred embodiment, the height adjustment unit includes a fixed wedge block fixed to the support platform, a movable wedge block placed on the fixed wedge block, and a vertical block located on one side of the fixed wedge block. The vertical block and the movable wedge block are connected by an adjusting screw. By turning the adjusting screw, the movable wedge block can be driven to move forward or backward along the fixed wedge block, thereby adjusting the height.

[0011] As a preferred embodiment, both the grinding power platform and the support platform are placed on the assembly platform.

[0012] A grinding method for a multi-dimensional precision grinding device for rotary kiln spherical tiles includes the following steps:

[0013] Step 1: Place the bearing base on the assembly platform and install the spherical bearing shell on the support frame;

[0014] Step 2: Install the adjustment components in the predetermined positions on the support platform according to the grinding requirements;

[0015] Step 3: Adjust the grinding amount and the height of the front and rear sides of the spherical tile by adjusting the components, and add grinding paste between the spherical tile and the bearing base;

[0016] Step 4: Under the control of the PLC controller, the two grinding power components drive the spherical tile to reciprocate in the bearing base as required under the preset degree control;

[0017] Step 5: If you need to increase the grinding amount, repeat steps 3 and 4 until the requirements are met.

[0018] Beneficial effects:

[0019] As described above, the multi-dimensional precision grinding device and grinding method for rotary kiln spherical tiles of the present invention have the following beneficial effects:

[0020] 1) The grinding device in this invention consists of a support platform, an adjustment component, a support frame, a grinding power platform, a grinding power component, a lifting shackle, a support shaft, etc. The adjustment component has two parts, front and rear. The adjustment component can not only adjust the hanging height of the spherical tile, but also adjust the height of both sides of the spherical tile, accurately control the grinding amount and the posture of the spherical tile during grinding, and perform grinding in a state close to the actual working condition of the spherical tile and the bearing base. This greatly improves the grinding quality of the spherical tile and the bearing base, thereby improving product quality, reducing the phenomenon of spherical tile scratches, and reducing labor intensity.

[0021] 2) In this invention, the installation position of the adjustment component on the support platform and the installation height of the spherical tile can be adjusted individually as needed, or the installation position of the adjustment component and the installation height of the spherical tile can be adjusted simultaneously to achieve multi-dimensional adjustment of the posture of the spherical tile in the bearing base.

[0034] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0035] like Figure 1 , Figure 2 As shown, this invention is a multi-dimensional precision grinding device for spherical tiles in a large rotary kiln, comprising a support platform 1, an adjustment assembly 2, a support frame 3, a grinding power platform 4, a grinding power assembly, a lifting shackle 8, and a support shaft 7. A support platform is located on each of the front and rear sides of the grinding power platform. The support platform 1 is mounted on an assembly platform. Two adjustment assemblies 2 are fixedly installed on the support platform 1 on the same side. The support shaft 7 is installed in the shaft holes of the adjustment assembly 2 and the support frame 3. The support frame 3 is used to suspend the spherical tile 9, with the centerline of the spherical tile 9 coinciding with the axis of the support shaft 7. The support frame 3 is a symmetrical structure centered on the axis of the support shaft 7. The lifting shackle 8 is installed on the support frame 3. The grinding power assembly is fixed to the grinding power platform 4 and connected to the lifting shackle 8. The spherical tile 9 is suspended above the bearing base 10 by the support frame 3. The two grinding power assemblies operate under the control of a preset program, pulling the spherical tile 9 to slide back and forth within the bearing base 10 around the axis of the support shaft 7 to achieve grinding.

[0036] As a specific embodiment of the present invention, the specific form and structure of the support platform 1 are not limited, as long as they can meet the support requirements. Specifically, the support platform 1 includes two platforms of equal height, which are welded or cast from an integral box-type structure.

[0037] like Figure 1 , Figure 3 As shown, each adjustment component 2 consists of a height adjustment unit 201 and a spherical rotary support 202 fixed on the height adjustment unit 201. The two height adjustment units 201 are respectively fixed on the support platform 1. The height adjustment units 201 can be adjusted to different heights to meet the requirements for adjusting the hanging height of the spherical tile 9. At the same time, the two height adjustment units 201 can be adjusted to different heights to meet the requirements for adjusting the grinding tilt angle of the spherical tile 9. The initial relative installation positions of the two adjustment components 2 on the support platform 1 can also be adjusted to meet the rotational attitude adjustment of the spherical tile 9 relative to the bearing base 10 around the vertical center.

[0038] It should be noted that the specific form and structure of the height adjustment unit 201 are not limited, as long as it can meet the height adjustment requirements. As a specific embodiment of the height adjustment unit 201, it includes a fixed wedge block fixed to the support platform, a movable wedge block placed on the fixed wedge block, and a vertical block located on one side of the fixed wedge block. The vertical block and the movable wedge block are connected by an adjusting screw. By turning the adjusting screw, the movable wedge block can be moved forward or backward along the fixed wedge block, thereby adjusting the height. This design offers high adjustment accuracy and convenient adjustment.

[0039] The support shaft 7 can be made of steel pipe or forged bar material, and the center of rotation of the support shaft 7 coincides with the center of rotation of the spherical tile 9.

[0040] The specific structure of support frame 3 is described below. Figure 4 , Figure 5 As shown, the support frame 3 includes a bushing 303 passing through the support shaft 7. A T-shaped plate 302 is horizontally symmetrically arranged on both sides of the bushing 303. A crossbeam plate 301 is provided on the two T-shaped plates 302. Two lifting shackles 8 are provided on the crossbeam plate 301. The lifting shackles 8 are connected to the grinding power assembly on the same side. Each T-shaped plate 302 is provided with at least one bolt hole 308. At least one bolt cooperates with the corresponding bolt hole 308 for hanging the spherical tile 9.

[0041] Specifically, the number of bolt holes 308 is not limited, but it should be designed to facilitate grinding while suspending the spherical tile 9. As a specific embodiment, such as... Figure 5 As shown, there are a total of four bolt holes on the two T-shaped plates 302. The four bolt holes are symmetrical about the axis of the bushing and about the front and back of the crossbeam plate to ensure the levelness and safety of the spherical tile 9 during hoisting.

[0042] In detail, the support frame 3 is also provided with reinforcing ribs to ensure the strength of the support frame 3. For example, longitudinal stiffening plates 307 are provided on the front and rear sides of both ends of the crossbeam plate 301, and transverse stiffening plates 306 are provided on the ends of the four longitudinal stiffening plates 307 away from the crossbeam plate 301. Longitudinal stiffening plates 305 are provided on the side of the transverse stiffening plates 306 away from the longitudinal stiffening plates 307. Transverse stiffening plates 304 are also provided on the side of the T-shaped plate 302 away from the crossbeam plate 301.

[0043] It should be noted that the two grinding power components are arranged spaced apart on the left and right. The specific form of the grinding power components is not limited, as long as they can achieve the lifting function. As a specific embodiment of the grinding power components, such as... Figure 1 and Figure 2 As shown, the grinding power assembly includes an electric drum 5 fixed on the grinding power platform 4 and a steel wire rope 6 wound on the electric drum 5. The steel wire rope 6 is connected to the lifting shackle 8.

[0044] Preferably, the drive motors of the two electric drums 5 are controlled by a preset program, and the motors drive the electric drums 5 to rotate the wire rope 6 and the support frame 3 around the support shaft 7.

[0045] In detail, the grinding power platform 401 is welded from shaped steel and steel plates. Other forms can also be adopted according to actual needs, as long as they meet the usage requirements.

[0046] The grinding method using the rotary kiln spherical tile multidimensional precision grinding device of the present invention specifically includes the following steps:

[0047] (1) Installation: First, place the bearing base 10 on the assembly platform. Based on the center height of the bearing base 10, determine the appropriate height of the support platform 1. Fix the support platform 1 on the assembly platform, fix the height adjustment unit 201 on the support platform 1, and fix the spherical rotary support 202 on the height adjustment unit 201. Hoist the spherical tile 9 with the support frame 3 above the bearing base 10. Install the support shaft 7 in the bushing 303 hole of the support frame 3. Install both ends of the support shaft 7 in the spherical rotary support 202. Install the grinding power platform 4 with the grinding power assembly on the assembly platform. Connect one end of the lifting shackle 8 to the support frame 3 and the other end to the wire rope 6.

[0048] (2) Adjustment: Adjust the grinding amount and the height of the front and rear sides of the spherical tile 9 by adjusting the components, and add grinding paste between the spherical tile 9 and the bearing base 10;

[0049] (3) Grinding: Under the action of the PLC controller, the two electric drums 5 run according to the predetermined program, and the steel wire rope 6 pulls the spherical tile 9 to move in the bearing base 10. After grinding for a period of time, the grinding amount is gradually increased and grinding continues until the target grinding amount is reached.

[0050] (4) Inspection: After grinding, clean off the grinding paste, lift the spherical tile 9 and rotate it at a certain angle, apply red lead powder to the inner spherical surface of the bearing base 10, and then place the spherical tile 9 back into the bearing base 10. Check the distribution of contact spots between the outer spherical surface of the spherical tile 9 and the inner spherical surface of the bearing base 10. The contact spots between the spherical surface of the spherical tile 9 and the bearing base 10 are 25×25mm. 2 There should be no fewer than 1 to 2 contact spots on the surface; if local contact high points appear, manual grinding can be used to repair them.

[0051] It should be noted that in step (2), the front and rear sides of the spherical tile 9 can be adjusted to be of the same height according to the actual grinding needs, such as... Figure 6 As shown, when adjusting the height, a level can be placed on the support frame 3 to facilitate height adjustment. Alternatively, the front and rear sides of the spherical tile 9 can be adjusted to different heights, causing the spherical tile 9 to be tilted, as shown. Figure 7 As shown, the relative installation positions of the two adjustment components 2 on the support platform 1 can also be changed to make the spherical tile 9 rotate, such as... Figure 8 As shown, this ensures multidimensional grinding.

[0052] Through steps (2) and (3), the height of the spherical tile can be changed by adjusting the height adjustment unit 201 after each grinding period, thereby changing the grinding amount. This step is repeated until the target grinding amount is reached, thus achieving precision grinding.

[0053] In summary, the grinding device and grinding method of the present invention can achieve precise control of the grinding amount of spherical tile 9 and multi-dimensional grinding, improve the grinding quality, avoid damage to spherical tile 9, and reduce labor intensity.

[0054] The present invention provides a detailed description of a multi-dimensional precision grinding device and method for rotary kiln spherical tiles. Specific examples have been used to illustrate the principles and specific implementation methods of the invention. These embodiments are merely illustrative of the methods and core concepts of the invention. It should be noted that any simple modifications, equivalent variations, and alterations made to the above embodiments based on the technical essence of the present invention by those skilled in the art fall within the protection scope of the present invention.
