Description

Technical Field

[0001] This utility model relates to the field of radial drilling machine technology, specifically a radial drilling machine stabilization mechanism. Background Technology

[0002] As is well known, in the existing machining field, radial drilling machines have become an indispensable key equipment in hole processing due to their high flexibility and wide processing range. They are widely used in industries such as aerospace, automobile manufacturing, and mold processing. Their core function is to achieve multi-angle and multi-station drilling operations through the extension, retraction, and rotation of the radial arm.

[0003] However, with the increasing demands of modern industry for machining accuracy and efficiency (especially the increasing demand for micron-level precision hole machining), the structural limitations of traditional radial drilling machines have gradually become apparent.

[0004] When machining large workpieces or drilling deep holes, the contact force between the drill bit and the material in traditional radial drilling machines causes slight displacement of the radial arm. This displacement accumulates into significant errors over long periods of machining, resulting in indentations or even deformation on the workpiece surface, directly affecting the yield rate of finished products. In addition, the positioning method of traditional equipment relies on manually adjusted bolts or pins for fixing. Operators need to repeatedly disassemble and fasten the fasteners to adjust the angle or height of the radial arm, which seriously restricts the efficiency of mass production. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a stabilizing mechanism for a radial drilling machine.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a stabilizing mechanism for a radial drilling machine, comprising a base plate, a rotating rod on one side of the base plate, a slide rail on one side of the rotating rod, a support arm on the slide rail, a limit assembly at the connection between the rotating rod and the base plate, and a fixing assembly on the rear side wall of the base plate.

[0009] To enable rapid locking and unlocking of the rotation angle of the rotating rod, this utility model improves upon the following: the limiting component includes a turntable, a rotating hole, a fixing hole, a connecting plate, a first hydraulic telescopic rod, and a limiting rod. The turntable is located at the lower end of the rotating rod and is fixedly connected to it. Multiple rotating holes are arranged on the turntable. The fixing hole is located on the side wall of the base plate, and the rotating hole and the fixing hole can coincide. The connecting plate is located on one side of the base plate and is fixedly connected to it. The first hydraulic telescopic rod is located at the upper end of the connecting plate. The limiting rod is located on one side of the first hydraulic telescopic rod and passes through the rotating hole and the fixing hole.

[0010] To effectively suppress the slippage of the support arm caused by processing vibration, this utility model improves upon the following: the fixing assembly includes a support box, a fixing rod, a fixing block, a support frame, a second hydraulic telescopic rod, and a fixing plate. The fixing plate is located on the rear side of the slide rail and is fixedly connected to it. The support box is located on the rear side wall of the base plate and is fixedly connected to it. The fixing rod passes through the support box. The fixing block is on the fixing rod and threadedly connected to it. The fixing block is in contact with and slidably connected to the inner side wall of the support box. The support frame passes through the support box and is connected to the upper side wall of the fixing block. The second hydraulic telescopic rod is located on the upper side wall of the support frame. The fixing plate is provided with multiple sets of limiting holes. A support hole is provided on the rear side of the support arm. The limiting holes and the support holes can coincide. The second hydraulic telescopic rod passes through the limiting holes and the support holes.

[0011] To achieve automated position adjustment of the fixing block within the support box, this utility model is improved by having a control motor installed on one side wall of the support box, and the fixing rod passing through the support box and connected to the output end of the control motor.

[0012] In order to make it possible to read the displacement of the slide rail intuitively, the present invention is improved by providing scale lines on the surface of the slide rail.

[0013] To support the collaborative operation requirements in automated production lines, the present invention is improved by including a remote control system in both the limiting component and the fixing component.

[0014] To significantly reduce sliding friction loss of the fixed block, the present invention includes the following improvement: the inner wall of the support box is provided with a wear-resistant ceramic liner.

[0015] To avoid sudden failure accidents caused by structural fatigue, the present invention has the following improvements: the support frame is made of carbon fiber composite material and has strain gauges embedded inside to monitor the bending deformation of the support frame in real time.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a stabilizing mechanism for a radial drilling machine, which has the following advantages:

[0018] The stabilizing mechanism of this radial drilling machine is equipped with a limit component. Through the cooperation of the rotating hole and the fixed hole on the turntable and the base plate, combined with the limit rod driven by the first hydraulic telescopic rod, it can realize the rapid switching and locking of the rotation angle of the rotating rod. The arrangement of multiple sets of holes provides a flexible angle adjustment range. The automatic insertion and removal mechanism of the hydraulic telescopic rod replaces the traditional manual pin operation, which significantly improves the efficiency of processing angle switching, while ensuring the accuracy and stability of rotation positioning.

[0019] Equipped with a fixed component, the support box forms a rigid transmission structure through a fixed rod and a threaded fixed block. When the control motor drives the fixed rod to rotate, the fixed block slides along the inner wall of the support box, forcing the support frame to produce lateral displacement. This, combined with the second hydraulic telescopic rod inserting into the corresponding limit holes on the support arm and the fixed plate, forms a constraint, effectively suppressing the lateral vibration and axial movement of the support arm during drilling, enhancing the overall structural rigidity, and ensuring the dynamic stability of the machining process.

[0020] The linkage design between the control motor and the fixed rod enables automated adjustment of the support frame position, eliminating the tedious steps of manually adjusting the screw in the traditional method. Attached Figure Description

[0029] Please see Figure 1-4 A stabilizing mechanism for a radial drilling machine includes a base plate 18. A rotating rod 17 is disposed on one side of the base plate 18, and a slide rail 1 is disposed on one side of the rotating rod 17. A support arm 19 is disposed on the slide rail 1. A limiting component is disposed at the connection between the rotating rod 17 and the base plate 18. A fixing component is disposed on the rear side wall of the base plate 18. The limiting component includes a turntable 5, a rotating hole 6, a fixing hole 16, a connecting plate 2, a first hydraulic telescopic rod 3, and a limiting rod 4. The turntable 5 is located at the lower end of the rotating rod 17 and is fixedly connected thereto. Multiple sets of rotating holes 6 are arranged on the turntable 5. The fixing holes 16 are located on the upper side wall of the base plate 18, and the rotating holes 6 and fixing holes 16 can overlap. The connecting plate 2 is located on one side of the base plate 18 and is fixedly connected thereto. The first hydraulic telescopic rod 3 is located at the upper end of the connecting plate 2. The limiting rod 4 is located on one side of the first hydraulic telescopic rod 3 and passes through the rotating hole 6 and the fixing hole 16. The fixing component includes a support box 9 and a fixing rod 15. The system comprises a fixed block 13, a support frame 11, a second hydraulic telescopic rod 12, and a fixed plate 7. The fixed plate 7 is located on the rear side of the slide rail 1 and is fixedly connected to it. The support box 9 is located on the rear side wall of the base plate 18 and is fixedly connected to it. The fixed rod 15 passes through the support box 9. The fixed block 13 is on the fixed rod 15 and is threadedly connected to it. The fixed block 13 is in contact with and slidably connected to the inner side wall of the support box 9. The support frame 11 passes through the support box 9 and is connected to the upper side wall of the fixed block 13. The second hydraulic telescopic rod 12 is located on the upper side wall of the support frame 11. The fixed plate 7 is provided with multiple sets of limiting holes 8. The support arm 19 is provided with a support hole 14 on its rear side. The limiting holes 8 and the support holes 14 can coincide. The second hydraulic telescopic rod 12 passes through the limiting holes 8 and the support holes 14. A control motor 10 is provided on one side wall of the support box 9. The fixed rod 15 passes through the support box 9 and is connected to the output end of the control motor 10.

[0030] During operation, the operator drives the rotating rod 17 to rotate around the axis of the base plate 18 via electric drive (this is the operating principle of a radial drilling machine, which will not be elaborated upon here). The turntable 5 at the lower end of the rotating rod 17 rotates synchronously. Multiple sets of rotating holes 6 are evenly distributed on the turntable 5 (common spacing corresponds to a 15° or 30° indexing angle design, compatible with ISO standard angle adjustment requirements). When the turntable 5 rotates to the target machining angle, the pre-set fixing hole 16 on the base plate 18 coincides with a certain rotating hole 6 on the turntable 5. At this time, the first hydraulic telescopic rod 3 is controlled to move downward, pushing the limit rod 4 vertically through the coincident rotating hole 6 and the fixing hole 16, forming a mechanical interlock, replacing the traditional bolt locking method, and shortening the angle locking time to within 2 seconds. After the angle of the rotating rod 17 is locked, the drive slide rail 1 moves along the axis of the rotating rod 17, driving the support arm 19 to the target position. In the standard working position (which is the operating principle of the radial drilling machine, and will not be elaborated in this article), when the support arm 19 moves to the preset position, the multiple sets of limiting holes 8 (arranged at standard intervals, in accordance with DIN standards) on the fixed plate 7 on the rear side of the slide rail 1 coincide with the support hole 14 at the rear end of the support arm 19, forming a second-level positioning reference. At this time, the control motor 10 is started, and the output of the control motor 10 drives the fixed rod 15 in the support box 9 to rotate. Under the limitation of the support box 9, the fixed block 13 is driven to slide along the inner wall of the support box 9 through the threaded transmission. The displacement of the fixed block 13 is converted into the lateral movement of the support frame 11. When it moves to the position where the limiting hole 8 coincides with the support hole 14, the second hydraulic telescopic rod 12 is extended in a controlled manner, passing through the limiting hole 8 of the fixed plate 7 and the support hole 14 of the support arm 19, forming an axial constraint, which significantly improves the ability to resist lateral cutting forces.

[0031] In practical use, it is necessary to be able to intuitively read the displacement of slide rail 1. In order to meet the above requirements, in this embodiment, the surface of slide rail 1 is provided with scale lines.

[0032] In practical use, a remote control module needs to be integrated to support the collaborative operation requirements in automated production lines. In order to meet the above requirements, in this embodiment, both the limiting component and the fixing component are equipped with a remote control system.

[0033] In actual use, it is necessary to significantly reduce the sliding friction loss of the fixed block 13. In order to meet the above requirements, in this embodiment, the inner wall of the support box 9 is provided with a wear-resistant ceramic liner.

[0034] In actual use, it is necessary to monitor the deformation in real time to avoid sudden failure accidents caused by structural fatigue. In order to meet the above requirements, in this embodiment, the support frame 11 is made of carbon fiber composite material and has strain gauges embedded inside to monitor the bending deformation of the support frame 11 in real time.
