Description

Technical Field

[0001] This utility model relates to the field of slewing bearing processing technology, specifically a drilling device for slewing bearing processing. Background Technology

[0002] Slewing bearings are a new type of mechanical component. They consist of inner and outer rings and rolling elements. Slewing bearings are large bearings capable of withstanding comprehensive loads, including large axial and radial loads and overturning moments.

[0003] When drilling holes in slewing bearings, a drilling device is required. However, the drilling device cannot be adjusted according to the diameter of the slewing bearing, which makes it inconvenient to drill slewing bearings of different diameters. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a drilling device for machining slewing bearings, which has the advantages of drilling slewing bearings of different diameters and solves the problem that drilling devices cannot drill slewing bearings of different diameters.

[0005] This utility model discloses a drilling device for machining slewing bearings, comprising a base, a rotating assembly on the top of the base, a limit assembly on the rotating assembly, drilling assemblies on both sides of the top of the base, each drilling assembly including a connecting plate with its bottom fixedly connected to the base, a frame fixedly connected to the top of the inner side of the connecting plate, an electric push rod on the outer side of the inner cavity of the frame, a moving plate at the output end of the electric push rod, sliders at both ends of the moving plate, grooves matching the sliders on both sides of the inner cavity of the frame, an electric telescopic rod at the bottom of the moving plate, a first motor at the output end of the electric telescopic rod, and a drill bit at the output end of the first motor. When drilling a slewing bearing, this utility model first places the slewing bearing on the rotating assembly, and then... The slewing bearing is positioned by the limit switch assembly. At this time, the electric push rod operates, which drives the moving plate to move. The moving plate moves in conjunction with the sliding groove and slider in the frame. The moving plate drives the electric telescopic rod to move, which in turn drives the first motor and the drill bit to move. When the drill bit reaches the desired drilling position, the electric push rod stops. At this time, the electric telescopic rod operates, which drives the first motor and the drill bit to move downward. When the drill bit contacts the slewing bearing, the first motor operates, which drives the drill bit to drill a hole in the slewing bearing. In this way, the drilling position can be adjusted according to the diameter of the slewing bearing, avoiding the situation where the drilling device cannot adjust the drilling position according to the diameter of the slewing bearing, which would otherwise cause inconvenience when drilling slewing bearings of different diameters.

[0006] This invention discloses a drilling device for machining slewing bearings. The rotating assembly includes a movable shaft, the bottom of which is fixedly connected to a base. A turntable is rotatably connected to the movable shaft. A gear ring is fixedly fitted onto the surface of the turntable, and a gear meshes with the surface of the gear ring. A second motor is located below the gear, its bottom fixedly connected to the base. The output end of the second motor is fixedly connected to the gear. The top of the turntable is fixedly connected to a limiting assembly. When drilling is required on the slewing bearing, the second motor first operates, driving the gear to rotate. The gear then drives the gear ring to rotate, which in turn drives the turntable to rotate. The movable shaft, in conjunction with the turntable, rotates, allowing the turntable to be used for drilling the slewing bearing. This makes drilling on the slewing bearing more convenient.

[0007] This utility model discloses a drilling device for machining slewing bearings. The limiting component includes a bidirectional hydraulic cylinder. A limiting plate is fixedly sleeved on the surface of the bidirectional hydraulic cylinder, and the bottom of the limiting plate is fixedly connected to the rotating component. The output end of the bidirectional hydraulic cylinder is provided with a positioning plate. When it is necessary to position the slewing bearing, the slewing bearing is first placed on the turntable. At this time, the bidirectional hydraulic cylinder runs, and the two positioning plates are moved by the bidirectional hydraulic cylinder. The two positioning plates position the inner side of the bidirectional hydraulic cylinder, so that the slewing bearing is more stable when drilling.

[0008] The present invention relates to a drilling device for machining slewing bearings, wherein the outer side of the connecting plate is provided with two support frames, and one end of the two support frames is fixedly connected to the base. The support frames can fix the connecting plate, thus improving the performance of the connecting plate during use and preventing the connecting plate from shaking during use, which would lead to instability of the components on the connecting plate.

[0009] The present invention relates to a drilling device for machining slewing bearings, wherein both sides of the electric push rod are fixedly connected to a fixing frame, and one end of the fixing frame is fixedly connected to the frame. The fixing frame can fix the electric push rod, thus improving the performance of the electric push rod during use and avoiding the situation where the electric push rod becomes loose during use, which would lead to instability in the movement of the moving plate driven by the electric push rod.

[0010] The present invention relates to a drilling device for machining slewing bearings, wherein the base is provided with an anti-slip pad on the top and anti-slip particles on the bottom of the anti-slip pad.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. When drilling a slewing bearing, this utility model first places the slewing bearing on the rotating assembly and positions it using a limiting assembly. At this point, an electric push rod operates, driving a moving plate. The moving plate moves via a groove and slider within the frame, which in turn moves an electric telescopic rod. The electric telescopic rod then moves a first motor and a drill bit. When the drill bit reaches the desired drilling position, the electric push rod stops. The electric telescopic rod then operates, driving the first motor and drill bit downwards. When the drill bit contacts the slewing bearing, the first motor operates, driving the drill bit to drill a hole in the slewing bearing. This allows for adjustment of the drilling position according to the diameter of the slewing bearing, avoiding the inconvenience of drilling devices that cannot adjust the drilling position based on the diameter of the slewing bearing when drilling slewing bearings of different diameters.

[0012] 2. When drilling is required on a slewing bearing, the second motor first runs, which drives the gear to rotate, which in turn drives the gear ring to rotate, which in turn drives the turntable to rotate. The movable shaft works in conjunction with the turntable to rotate, and the turntable can then be used to drill holes in the slewing bearing. This makes drilling holes in the slewing bearing more convenient. When it is necessary to position the slewing bearing, first place the slewing bearing on the turntable. At this time, the bidirectional hydraulic cylinder runs, and the two positioning plates are moved by the bidirectional hydraulic cylinder. The two positioning plates position the inner side of the bidirectional hydraulic cylinder, so that the slewing bearing is more stable when drilling. The support frame can fix the connecting plate, which makes the connecting plate more effective during use and prevents it from shaking, which could lead to instability of the components on the connecting plate. The fixing bracket can be used to fix the electric push rod, which makes the electric push rod work better and avoids the situation where the electric push rod becomes loose during use, which would cause the moving plate to move unstablely.

[0015] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0016] Please see Figure 1-5The present invention discloses a drilling device for machining a slewing bearing, comprising a base 1, a rotating assembly 5 on the top of the base 1, a limiting assembly 3 on the rotating assembly 5, and drilling assemblies 2 on both sides of the top of the base 1. Each drilling assembly 2 includes a connecting plate 201, the bottom of which is fixedly connected to the base 1. A frame 207 is fixedly connected to the top of the inner side of the connecting plate 201. An electric push rod 204 is provided on the outer side of the inner cavity of the frame 207, and a moving plate 205 is provided at the output end of the electric push rod 204. Both ends of the movable plate 205 are provided with sliders 208, and both sides of the inner cavity of the frame 207 are provided with sliding grooves 206 that are adapted to the sliders 208. The bottom of the movable plate 205 is provided with an electric telescopic rod 209, the output end of the electric telescopic rod 209 is provided with a first motor 2010, and the output end of the first motor 2010 is provided with a drill bit 2011. When drilling is required on the slewing bearing, the slewing bearing is first placed on the rotating assembly 5, and the slewing bearing is positioned by the limiting assembly 3. At this time, the electric push rod 204 operates, driving the moving plate 205 to move. The moving plate 205 moves in conjunction with the sliding groove 206 and slider 208 in the frame 207. The moving plate 205 drives the electric telescopic rod 209 to move, which in turn drives the first motor 2010 and the drill bit 2011 to move. When the drill bit 2011 moves to the required drilling position, the electric push rod 204 stops operating. At this time, the electric telescopic rod 209 operates, driving the first motor 2010 and the drill bit 2011 to move downwards. When the drill bit 2011 contacts the slewing bearing, the first motor 2010 operates, driving the drill bit 2011 to drill a hole in the slewing bearing. This allows the drilling position to be adjusted according to the diameter of the slewing bearing, avoiding the situation where the drilling device cannot adjust the drilling position according to the diameter of the slewing bearing, which would otherwise cause inconvenience when drilling slewing bearings of different diameters.

[0017] The rotating assembly 5 includes a movable shaft 501, the bottom of which is fixedly connected to the base 1. A turntable 503 is rotatably connected to the movable shaft 501. A gear ring 502 is fixedly sleeved on the surface of the turntable 503. A gear 504 meshes with the surface of the gear ring 502. A second motor 505 is located below the gear 504, and the bottom of the second motor 505 is fixedly connected to the base 1. The output end of the second motor 505 is fixedly connected to the gear 504. The top of the turntable 503 is fixedly connected to the limiting assembly 3. When the slewing bearing needs to be rotated for drilling, the second motor 505 first runs, driving the gear 504 to rotate. The gear 504 then drives the gear ring 502 to rotate, which in turn drives the turntable 503 to rotate. The movable shaft 501 rotates in conjunction with the turntable 503, allowing the slewing bearing to be rotated for drilling. This makes drilling the slewing bearing more convenient.

[0018] The limiting component 3 includes a bidirectional hydraulic cylinder 301. A limiting plate 302 is fixedly sleeved on the surface of the bidirectional hydraulic cylinder 301, and the bottom of the limiting plate 302 is fixedly connected to the rotating component 5. The output end of the bidirectional hydraulic cylinder 301 is provided with a positioning plate 303. When it is necessary to position the slewing bearing, the slewing bearing is first placed on the turntable 503. At this time, the bidirectional hydraulic cylinder 301 runs, and the two positioning plates 303 are moved by the bidirectional hydraulic cylinder 301. The two positioning plates 303 position the inner side of the bidirectional hydraulic cylinder 301, so that the slewing bearing is more stable when drilling.

[0019] Two support frames 202 are provided on the outer side of the connecting plate 201, and one end of the two support frames 202 is fixedly connected to the base 1. The support frames 202 can fix the connecting plate 201, so that the connecting plate 201 is more effective in use and avoids the connecting plate 201 from shaking during use, which would lead to the unstable use of the components on the connecting plate 201.

[0020] Both sides of the electric push rod 204 are fixedly connected to the fixing bracket 203, and one end of the fixing bracket 203 is fixedly connected to the frame 207. The fixing bracket 203 can fix the electric push rod 204, so that the electric push rod 204 performs better when used and avoids the electric push rod 204 from becoming loose during use, which would cause the electric push rod 204 to drive the moving plate 205 to move unstably.

[0021] The base 1 has an anti-slip pad 4 on top and anti-slip particles on the bottom.

[0022] When using this utility model: When drilling is required on the slewing bearing, first place the slewing bearing on the rotating assembly 5, and position the slewing bearing using the limiting assembly 3. At this time, the electric push rod 204 operates, driving the moving plate 205 to move. The moving plate 205 moves through the sliding groove 206 and slider 208 in the frame 207, which in turn drive the electric telescopic rod 209 to move. The electric telescopic rod 209 then drives the first motor 2010 and the drill bit 2011 to move. The drill bit 2011 moves to the required drilling position. When the hole is in position, the electric push rod 204 stops operating. At this time, the electric telescopic rod 209 operates, driving the first motor 2010 and the drill bit 2011 to move downwards. When the drill bit 2011 contacts the slewing bearing, the first motor 2010 operates, driving the drill bit 2011 to drill a hole in the slewing bearing. This allows the drilling position to be adjusted according to the diameter of the slewing bearing, avoiding the situation where the drilling device cannot adjust the drilling position according to the diameter of the slewing bearing, which would otherwise lead to inconvenience when drilling slewing bearings of different diameters.
