Technical Field

[0001] The utility model relates to the technical field of positioning tooling, in particular to a bearing spacer ring drilling tooling. Background Art

[0002] A bearing spacer is an annular part used to mount bearings. It is usually made of metal materials such as steel or other alloys. The main function of a bearing spacer is to provide support and maintain clearance between the bearing and the shaft, and ensure that the bearing can be installed and operated correctly. Currently, multiple holes are drilled on the side of the spacer to more conveniently supply lubricating oil or grease to the bearing. These holes also help dissipate heat, helping the bearing maintain an appropriate temperature when operating under high load or at high speed.

[0003] In the existing technology, the drilling of bearing spacer rings is generally done by having a scriber mark the holes to be drilled, then fixing them with a traditional clamp, drilling, rotating the spacer ring, and gradually drilling the remaining holes. However, due to problems with clamping accuracy, the holes are not located in the center of the spacer ring, the size also deviates, the peripheral hole spacing is also uneven, and work efficiency is also low. Utility Model Content

[0004] The utility model proposes a bearing spacer ring drilling tool. This solution can accurately control the hole position, hole diameter and hole spacing of the spacer ring drilling through the coordinated use of a positioning base, a pressure plate and a screw rod, effectively solving the problem of poor drilling accuracy of the bearing spacer ring and improving work efficiency.

[0007] A further technical solution is that the inner cavity height of the sinking groove is consistent with the thickness of the spacer ring.

[0008] A further technical solution is that the diameter of the pressing plate is larger than the inner diameter of the ring body.

[0009] A further technical solution is that the through hole is located at the center of the pressing plate, and the inner diameter of the through hole is slightly larger than the diameter of the screw.

[0010] A further technical solution is that a buffer pad is fixed to the bottom surface of the pressure plate.

[0011] A further technical solution is that a docking block is fixed to the bottom of the positioning base, and the cross section of the docking block is rectangular.

[0012] The working principle and beneficial effects of this application are:

[0013] This solution uses a positioning base, a pressure plate, a screw and other structures to set the shape of the sinking groove to be consistent with the spacer ring, and then opens a positioning hole on the sinking groove according to the drilling requirements, so that the hole position, hole diameter and hole spacing of the spacer ring can be accurately controlled, effectively solving the problem of poor drilling accuracy of the bearing spacer ring, improving work efficiency, ensuring the uniformity of oil supply to the bearing during high-speed operation, avoiding the problems of bearing heating and uneven wear of various parts of the bearing caused by uneven oil supply, and improving the service life of the bearing.

[0022] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-Figure 5 As shown, a bearing spacer ring drilling tool includes a positioning base 1, a sunken groove 2 is opened on the positioning base 1, a plurality of positioning holes 4 are opened on the side wall of the sunken groove 2, a plurality of positioning blocks 3 are fixed inwardly on the inner wall of the sunken groove 2, and a threaded hole 5 is opened at the center position of the bottom of the sunken groove 2.

[0024] It also includes a spacer ring 6, which includes a ring body 61. The outer diameter of the ring body 61 is consistent with the inner diameter of the sinking groove 2, and the outer end of the ring body 61 is provided with a positioning groove 62 that matches the positioning block 3; a pressure plate 7, which is buckled on the top of the ring body 61, and a through hole 8 is provided at the center position. A screw rod 9 is vertically passed through the through hole 8, and the screw rod 9 passes through the spacer ring 6 and is threadedly connected to the threaded hole 5, and the top of the screw rod 9 locks the pressure plate 7 and the positioning base 1 through the screw sleeve 10 and the gasket 11.

[0025] A bearing spacer ring is an annular part used to mount bearings. Currently, multiple holes are drilled on the side of the spacer ring to more conveniently supply lubricating oil or grease to the bearing. Drilling holes in the bearing spacer ring is generally done by having a scriber mark the holes to be drilled. The holes are then fixed with a traditional fixture before drilling. The spacer ring is rotated and the remaining holes are gradually drilled. Due to issues with clamping accuracy, the holes are not located in the center of the spacer ring, and the size also deviates. The peripheral hole spacing is also uneven, resulting in low work efficiency.

[0026] In this solution, the sinking trough 2 is manufactured in accordance with the shape and punching requirements of the spacer ring 6 during production. The ring body 61 is buckled into the inner cavity of the sinking groove 2, and the positioning groove 62 is engaged with the positioning block 3. This engagement limits the ring body 61, making it unable to move or rotate in the horizontal direction. The screw 9 passes through the inner side of the ring body 61 and is threadedly connected to the threaded hole 5. The screw 9 is in a fully tightened state, and the pressure plate 7 is overlapped on the top of the spacer ring 6. The gasket 11 and the screw sleeve 10 are tightly abutted against the spacer ring 6 in turn. Through the extrusion of the screw sleeve 10 and the gasket 11, the pressure plate 7 is firmly abutted against the spacer ring 6, so that the bottom end of the spacer ring 6 is tightly fitted with the bottom end of the inner wall of the sinking groove 2, thereby ensuring that during the drilling process, the movement of the spacer ring 6 and the positioning base 1 remain completely consistent, ensuring the accuracy of the drilling, and the drill bit can penetrate the positioning hole 4 to drill the ring body 61. Since multiple positioning holes 4 are arranged equidistantly in a ring, the drilling of the ring body 61 through the positioning hole 4 can also ensure equidistant arrangement.

[0027] The height of the inner cavity of the sinking trough 2 is consistent with the thickness of the spacer ring 6. In this embodiment, the height of the inner cavity of the sinking trough 2 is consistent with the height of the spacer ring 6. Therefore, when the bottom end of the spacer ring 6 is tightly fitted with the bottom end of the inner wall of the sinking trough 2, the top end of the spacer ring 6 and the surface of the positioning base 1 will also be at the same horizontal position, so that the positioning hole 4 will also be located at the center position of the ring body 61 in the height direction, thereby ensuring that the drilling hole of the ring body 61 is located at its center position.

[0028] Furthermore, the diameter of the pressing plate 7 is larger than the inner diameter of the ring body 61. The through hole 8 is located at the center of the pressing plate 7, and the inner diameter of the through hole 8 is slightly larger than the diameter of the screw 9.

[0029] In this solution, the diameter of the pressure plate 7 is slightly larger than the inner diameter of the ring body 61, ensuring that the edge positions of the pressure plate 7 can abut against the top of the ring body 61, thereby ensuring that the pressure plate 7 can apply a relatively uniform downward pressure to the ring body 61. The inner diameter of the through hole 8 is slightly larger than the diameter of the screw 9 to ensure that the pressure plate 7 can smoothly pass through the screw 9, but will not cause a large displacement during the process of twisting the screw sleeve 10.

[0030] In addition, a buffer pad is fixed to the bottom surface of the pressing plate 7. In this solution, the material of the buffer pad can be set to rubber. Through the setting of the buffer pad, the surface of the ring body 61 can be protected to prevent the friction during the extrusion and rotation of the pressing plate 7 from damaging the surface of the ring body 61.

[0031] like Figure 6 As shown, a docking block 12 is fixed to the bottom of the positioning base 1 , and the cross section of the docking block 12 is rectangular.

[0032] In this solution, the docking block 12 is used to connect with an external rotating mechanism, which drives the positioning base 1 and the spacer ring 6 to rotate, making it convenient to drill holes around the ring body 61. The docking block 12 is set to a structure with a rectangular cross-section, which is conducive to precise positioning of the positioning base 1 during installation and more convenient for aligning the drill bit with the positioning hole 4.

[0033] Working principle:

[0034] The user can buckle the ring body 61 into the inner cavity of the sinking groove 2 so that the positioning groove 62 is engaged with the positioning block 3, thereby fixing the ring body 61 in the inner cavity of the sinking groove 2 and preventing it from moving or rotating in the horizontal direction. Then the user passes the screw rod 9 through the inner side of the ring body 61 and screws the screw rod 9 into the threaded hole 5 until the screw rod 9 is completely tightened. Then the user puts the pressing plate 7 on the outer end of the screw rod 9 so that the screw rod 9 passes through the through hole 8 and the pressing plate 7 is overlapped on the top of the spacer ring 6. The user puts the gasket 11 on the outer end of the screw 9 and threads the screw sleeve 10 onto the screw 9 until the gasket 11 and the screw sleeve 10 are tightly abutted against the spacer ring 6 in turn. Through the extrusion of the screw sleeve 10 and the gasket 11, the pressure plate 7 is firmly abutted against the spacer ring 6, so that the bottom end of the spacer ring 6 is tightly fitted with the bottom end of the inner wall of the sinking groove 2. Finally, the user connects the docking block 12 with the rotating mechanism and aligns the drill bit device with the positioning hole 4. The drill bit passes through the positioning hole 4 to drill the ring body 61.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
