Description

Technical Field

[0001] This utility model relates to the field of drilling technology, and more specifically, to a drilling device for processing steel ring forgings. Background Technology

[0002] Slewing bearings typically consist of four main components: an inner ring, an outer ring, rolling elements, and spacers. During production, the inner and outer steel ring forgings of a slewing bearing require equidistant drilling along their circumference. These mounting holes secure the outer and inner rings of the slewing bearing to the end faces of the stationary and rotating components, respectively, allowing the rotating component to rotate on the stationary component.

[0003] When grinding the surface of steel ring forgings, the required drilling distances vary depending on the size of the steel rings. When the drilling device needs to drill at different spacing positions, the operator needs to manually adjust the position of the drilling head. Due to the low precision of manual adjustment, the position distribution between holes is easily uneven when drilling in a ring. In view of this, we propose a drilling device for processing steel ring forgings. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a drilling device for processing steel ring forgings, so as to solve the technical problem that the current manual adjustment of the position of the drilling head is of low accuracy and easily leads to uneven position distribution between holes.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a drilling device for processing steel ring forgings, including a worktable, a horizontal plate fixedly connected to the upper end face of the worktable, a hydraulic cylinder fixedly connected to the upper end face of the horizontal plate, and a limit component arranged through the side wall of the horizontal plate at the telescopic end of the hydraulic cylinder.

[0006] The limiting component includes a fixed frame fixedly connected to the telescopic end of the hydraulic cylinder. A motor A is fixedly connected inside the fixed frame. A connecting rod is fixedly connected to the telescopic end of the motor A. The tail end of the connecting rod passes through the side wall of the fixed frame and is fixedly connected to a limiting plate. The limiting plate has several limiting holes at equal intervals.

[0007] This invention enables the slide rod to drive several punching heads to expand and contract at equal intervals, thereby adapting to the surface punching requirements of steel ring forging bodies of different sizes and improving the punching accuracy of different steel ring forging bodies.

[0008] Preferably, the limiting holes are curved and spirally distributed at equal intervals around the axis of the limiting holes. A connecting plate is movably arranged on the surface of the connecting rod through a bearing seat. The upper end face of the connecting plate is fixedly connected to the lower end face of the fixing frame through a fixing rod.

[0009] Preferably, the surface of the connecting plate is provided with a plurality of sliding grooves relative to the position of the limiting hole, and each sliding groove is slidably connected to a sliding rod.

[0010] Preferably, the upper surface of the workbench extends with a plurality of material discharge grooves relative to the position of the slide groove, and the sidewalls of the material discharge grooves are set as inclined surfaces.

[0011] Preferably, a limiting rod is fixedly connected to the lower end face of the slide rod, and the surface of the limiting rod is simultaneously slidably connected within the limiting hole. A punching head is fixedly connected to the tail end of the slide rod through the side wall of the slide groove.

[0012] Preferably, the upper surface of the workbench is provided with a rotating groove, and a bidirectional threaded rod is rotatably connected in the rotating groove. Clamping plates are symmetrically connected to the surface of the bidirectional threaded rod.

[0013] Preferably, the surface of the clamping plate abuts against the steel ring forging body, and the head end of the bidirectional threaded rod is fixedly connected to the motor B through the side wall of the rotating groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, by setting a limiting component, can utilize the connection between the connecting plate and the limiting plate. When the limiting plate rotates, the limiting hole limits the limiting rod. When the limiting plate rotates, it simultaneously drives the sliding rod to move in the sliding groove. Furthermore, through an equal number of limiting holes and sliding rods, the sliding rods drive several drilling heads to expand and contract at equal intervals, thereby adapting to the surface drilling requirements of steel ring forgings of different sizes and improving the drilling accuracy of different steel ring forgings.

[0016] 2. This utility model also features a material discharge chute positioned to match the location of the chute. This allows for the collection and placement of waste generated during the drilling operation. Furthermore, the inclined surfaces on both sides of the material discharge chute facilitate the cleaning and removal of debris and waste by workers, preventing dust accumulation and improving the cleaning effect.

[0017] 3. This utility model also features a limiting plate and several limiting holes. The curved surface of the limiting holes generates a torque force on the limiting rod when the limiting plate rotates, and the curved surface continuously pushes the limiting rod, allowing it to move within the groove. This ensures that the limiting rod does not get stuck during movement and allows multiple limiting rods to be evenly distributed at equal intervals. This improves the variability and practicality of the drilling head position and avoids the problem of low precision in manual adjustment of the drilling head position. Attached Figure Description

[0026] like Figures 1 to 6 As shown, the present invention relates to a drilling device for processing steel ring forgings, including a workbench 1, a horizontal plate fixedly connected to the upper end face of the workbench 1, a hydraulic cylinder 2 fixedly connected to the upper end face of the horizontal plate, and a limit component 3 arranged through the side wall of the horizontal plate at the telescopic end of the hydraulic cylinder 2.

[0027] The limiting assembly 3 includes a fixed frame 301 fixedly connected to the telescopic end of the hydraulic cylinder 2. A motor A302 is fixedly connected inside the fixed frame 301. A connecting rod is fixedly connected to the telescopic end of the motor A302. The tail end of the connecting rod passes through the side wall of the fixed frame 301 and is fixedly connected to a limiting disc 303. The limiting disc 303 has several limiting holes 304 at equal intervals. The limiting holes 304 are curved and spirally distributed at equal intervals around the axis of the limiting holes 304. By setting the limiting disc 303 and the several limiting holes 304, The curved surface of the limiting hole 304 can generate a torque force on the limiting rod 308 when the limiting plate 303 rotates, and its curved surface continuously generates a thrust on the limiting rod 308, allowing it to move within the slide groove 306. This ensures that the limiting rod 308 does not get stuck during movement, and at the same time, it allows multiple limiting rods 308 to be evenly distributed at equal intervals, improving the variability and practicality of the position of the punch head 309, and avoiding the problem of low precision in manually adjusting the position of the punch head 309.

[0028] In this embodiment of the utility model, a connecting plate 305 is movably arranged on the surface of the connecting rod via a bearing seat. The upper end face of the connecting plate 305 is fixedly connected to the lower end face of the fixing frame 301 via a fixing rod. A plurality of sliding grooves 306 are formed on the surface of the connecting plate 305 relative to the position of the limiting hole 304. Each sliding groove 306 is slidably connected to a sliding rod 307. A limiting rod 308 is fixedly connected to the lower end face of the sliding rod 307. The surface of the limiting rod 308 is simultaneously slidably connected within the limiting hole 304. A punching head 309 is fixedly connected to the tail end of the sliding rod 307 through the side wall of the sliding groove 306. The limiting component 3, through the connection between the connecting plate 305 and the limiting plate 303, limits the limiting rod 308 through the limiting hole 304 when the limiting plate 303 rotates. When the limiting plate 303 rotates, it simultaneously drives the sliding rod 307 to move within the sliding groove 306. Furthermore, through an equal number of limiting holes 304 and sliding rods 307, the sliding rods 307 drive several drilling heads 309 to expand and contract at equal intervals, thereby adapting to the surface drilling requirements of steel ring forging bodies of different sizes and improving the drilling accuracy of different steel ring forging bodies.

[0029] In this embodiment of the invention, a plurality of material discharge troughs 7 are provided on the upper surface of the workbench 1 relative to the position of the slide 306. The side walls of the material discharge troughs 7 are set as inclined surfaces. By setting the material discharge troughs 7 and positioning them to match the position of the slide 306, the waste generated during the drilling operation of the drilling head 309 can be collected and placed. Furthermore, the inclined surfaces on both sides of the material discharge troughs 7 facilitate the cleaning and removal of debris and waste by the workers, avoiding dust accumulation and improving the cleaning effect. A rotating groove is provided on the upper end face of 1. A bidirectional threaded rod 4 is rotatably connected in the rotating groove. A clamping plate 5 is symmetrically connected to the surface of the bidirectional threaded rod 4. The surface of the clamping plate 5 abuts against the steel ring forging body. The head end of the bidirectional threaded rod 4 passes through the side wall of the rotating groove and is fixedly connected to a motor B6. By setting the motor B6 and the bidirectional threaded rod 4, the motor B6 can drive the bidirectional threaded rod 4 to rotate, so that the clamping plate 5 can move relative to the steel ring forging body and clamp it, so that the steel ring forging body can be fixed on the worktable 1.

[0030] Working Principle: This embodiment provides a drilling device for processing steel ring forgings. In use, the steel ring forging body is first placed at the center of the upper end face of the worktable 1. Then, the operation of motor B6 drives the bidirectional threaded rod 4 to rotate, thereby moving the relative positions of the two clamping plates 5. The clamping plates 5 can clamp and fix the inner wall of the steel ring forging body, so that the steel ring forging body can be fixedly arranged on the worktable 1. At this time, the operation of motor A302 drives the limiting plate 303 to rotate, thereby limiting the position of the limiting rod 308 by the limiting hole 304, and allowing the sliding rods 307 to move at equal intervals according to the arc surface of the limiting hole 304. This ensures that the distance between each sliding rod 307 is equal, so that the position of the drilling head 309 can be evenly distributed during adjustment. Then, the stretching movement of hydraulic cylinder 2 drives the drilling head 309 downward to drill holes in the surface of the steel ring forging body.

[0031] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
