Description

Technical Field

[0001] This invention relates to the field of shipbuilding processing technology, and in particular to a drilling device and a method for drilling holes in a rudder bearing seat using the device. Background Technology

[0002] Currently, the mounting holes for safety rings on the rudder bearing seats of ship rudder booms need to be custom-made on-site as needed. Some ships require safety rings to be installed on both the upper and lower surfaces of the rudder bearing seats due to design requirements. The specific machining sequence for the mounting holes for safety rings is as follows: after smoothing the upper and lower surfaces of the rudder bearing seats, multiple mounting holes are drilled around the bearing holes on the rudder bearing seats using safety rings. However, due to the large space constraints on machining mounting holes on the rudder boom, directly machining mounting holes on the rudder bearing seats is difficult and inefficient. In particular, the mounting holes for safety rings on the lower surface require drilling vertically upwards, further increasing the machining difficulty. Summary of the Invention

[0036] Compared with the prior art, the drilling device and method for drilling holes in a rudder bearing seat according to embodiments of the present invention have the following advantages:

[0037] This invention provides a first clamping block and a second clamping block on both sides of the rudder bearing seat along the vertical direction. The two ends of a connecting rod are adjustablely connected to the first and second clamping blocks, respectively, allowing the first gap between the first and second clamping blocks to be adjustable. Therefore, the first and second clamping blocks can be clamped onto both sides of the rudder bearing seat along the vertical direction by reducing the first gap to fix their positions. Furthermore, the drill base of the drilling rig is mounted on the first clamping block, and the drill bit of the drilling rig is vertically positioned and facing the second clamping block on the drill base, with a second gap in the horizontal direction between it and the first clamping block. This allows the drilling rig to... Drilling is performed on the end face of the rudder bearing seat. Furthermore, after the first and second clamping blocks are clamped onto the rudder bearing seat, the first gap can be increased to flexibly adjust the horizontal position of the first and second clamping blocks, thereby adjusting the horizontal position of the drilling rig. After the drill bit of the drilling rig is aligned with the drilling point, the first gap is reduced to clamp the first and second clamping blocks onto the rudder bearing seat, fixing the position of the drilling rig. This allows the drilling rig to readjust the drilling position without having to be removed from the first clamping block. In summary, this invention allows for the convenient machining of multiple mounting holes on the upper and lower end faces of the rudder bearing seat with high machining efficiency.

[0042] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0043] In the description of this invention, it should be understood that the terms "top", "bottom", "inner", "outer", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0044] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0045] like Figures 1 to 3 As shown, a drilling device of the present invention includes a first clamping block 1, a second clamping block 2, a connecting rod 3, and a drilling machine 4. The first clamping block 1 and the second clamping block 2 are arranged opposite each other in a vertical direction, and a first gap is formed between the first clamping block 1 and the second clamping block 2. The two ends of the connecting rod 3 are respectively adjustablely connected to the first clamping block 1 and the second clamping block 2 to adjust the first gap. The drilling machine 4 includes a drill base 41 and a drill bit 42. The drill base 41 is disposed on the end face of the first clamping block 1 away from the second clamping block 2. The drill bit 42 is vertically disposed on the drill base 41 and faces the second clamping block 2. The drill bit 42 and the first clamping block 1 form a second gap in the horizontal direction.

[0046] In the above technical solution, the size of the first gap between the first clamping block 1 and the second clamping block 2 is adjustable. Therefore, the first clamping block 1 and the second clamping block 2 can be clamped on both sides of the rudder bearing seat 5 in the vertical direction by reducing the first gap to fix the position of the first clamping block 1 and the second clamping block 2. Furthermore, the drilling rig 4 can perform drilling operations on the end face of the rudder bearing seat 5 on the first pressure block. Furthermore, after the first clamping block 1 and the second clamping block 2 are clamped on the rudder bearing seat 5, the position of the first clamping block 1 and the second clamping block 2 in the horizontal direction can be flexibly adjusted by increasing the first gap, thereby adjusting the horizontal position of the drilling rig 4. Position: After the drill bit 42 of the drilling rig 4 is aligned with the point to be drilled, the first clamping block 1 and the second clamping block 2 are clamped to the rudder bearing seat 5 by reducing the first gap, thus fixing the position of the drilling rig 4. This allows the drilling rig 4 to readjust the drilling position without having to be removed from the first clamping block 1. In summary, this invention allows for the convenient processing of multiple mounting holes on the upper and lower surfaces of the rudder bearing seat 5 with high processing efficiency. The second gap is set to prevent the drill bit 42 and the first clamping block 1 from overlapping in the horizontal direction, indicating that the drill bit 42 will not encounter the first clamping block 1 when drilling in the vertical direction.

[0047] Furthermore, it also includes two connecting bosses 6 respectively provided on the first clamping block 1 and the second clamping block 2. The two connecting bosses 6 are arranged opposite to each other, and the two ends of the connecting rod 3 are respectively threaded to the two connecting bosses 6, so that the size of the first gap can be adjusted by relative rotation between the first clamping block 1, the second clamping block 2 and the connecting rod 3.

[0048] Furthermore, in order to adapt to the machining of various ship rudder bearing seats 5, the length of the first clamping block 1 and the second clamping block 2 is 140mm to 160mm. Preferably, the connecting rod 3 is an M16 to M25 screw, and both connecting bosses 6 are provided with threaded holes that match the external threads of the connecting rod 3.

[0049] Furthermore, the drilling rig 4 is a magnetic base drill, and the drill base 41 is magnetically connected to the first clamping block 1 to facilitate the assembly and disassembly of the drilling rig 4 to the first clamping block 1.

[0050] Furthermore, both the first clamping block 1 and the second clamping block 2 are long strips of steel, which allows the first clamping block 1 and the second clamping block 2 to be effectively attached to the end face of the rudder bearing seat 5 and to reduce the weight of the first clamping block 1 and the second clamping block 2. The first clamping block 1 and the second clamping block 2 are preferably channel steel.

[0051] The present invention also relates to a method for drilling a hole in a rudder bearing seat 5 using the aforementioned drilling device, comprising the following steps: (S1) placing the first clamping block 1 and the second clamping block 2, respectively, across the bearing hole 51 of the rudder bearing seat 5 on opposite sides of the rudder bearing seat 5 in the vertical direction; (S2) placing the connecting rod 3 vertically inside the bearing hole 51 of the rudder bearing seat 5; (S3) connecting the two ends of the connecting rod 3 to the first clamping block 1 and the second clamping block 2 respectively; (S4) reducing the first distance between the first clamping block 1 and the second clamping block 2, so that the first clamping block 1 and the second clamping block 2 clamp the rudder bearing seat 5; (S5) aligning the drill bit 42 of the drilling machine 4 with any point to be drilled on the end face of the rudder bearing seat 5 located on one side of the first clamping block 1, and installing the drill base 41 of the drilling machine 4 onto the end face of the first clamping block 1 away from the second clamping block 2; (S6) drilling the rudder bearing seat 5 with the drill bit 42 of the drilling machine 4, so that the drill bit 42... (S7) Increase the first distance between the first clamping block 1 and the second clamping block 2 to make the first clamping block 1 movable; (S8) Adjust the attitude of the first clamping block 1 in the horizontal direction so that the drill bit 42 of the drilling machine 4 is aligned with any un-drilled mounting hole on the end face of the rudder bearing seat 5 located on one side of the first clamping block 1; (S9) Decrease the first distance between the first clamping block 1 and the second clamping block 2 so that the first clamping block 1 and the second clamping block 2 clamp the rudder bearing seat 5; (S10) Drill the rudder bearing seat 5 with the drill bit 42 so that the mounting hole is formed at the mounting point aligned with the drill bit 42; (S11) Repeat steps (S7) to (S10) until mounting holes are drilled at all the mounting points on the end face of the rudder bearing seat 5 located on one side of the first clamping block 1; (S12) Remove the drilling machine 4, connecting rod 3, first clamping block 1 and second clamping block 2.

[0052] Furthermore, in order to machine the mounting hole on the other end face of the rudder bearing seat 5, the method further includes the following steps: between step (S11) and step (S12) there are steps (Sa1), (Sa2) and (Sa3) in sequence; (Sa1) dismantle the drilling rig 4; (Sa2) define the original first clamping block 1 as the second clamping block 2, and define the original second clamping block 2 as the first clamping block 1; (Sa3) execute steps (S5) to (S11).

[0053] Furthermore, in order to tap the mounting hole, the method further includes the following steps: between steps (S11) and (S12) are steps (Sb1), (Sb2), (Sb3), (Sb4), (Sb5), and (Sb6) in sequence; (Sb1) replacing the drill bit 42 of the drilling rig 4 with a tapping drill bit 42; (Sb2) increasing the first distance between the first clamping block 1 and the second clamping block 2, so that the first clamping block 1 is movable; (Sb3) adjusting the posture of the first clamping block 1 in the horizontal direction, Align the drill bit 42 of the drill rig 4 with any untapping mounting hole on the end face of the rudder bearing seat 5 located on one side of the first clamping block 1; (Sb4) reduce the first distance between the first clamping block 1 and the second clamping block 2, so that the first clamping block 1 and the second clamping block 2 clamp the rudder bearing seat 5; (Sb5) tap the rudder bearing seat 5 with the drill bit 42, so that a thread is formed in the mounting hole aligned with the drill bit 42; (Sb6) repeat steps (Sb2) to (Sb5) until all mounting holes on the end face of the rudder bearing seat 5 located on one side of the first clamping block 1 are threaded.

[0054] Furthermore, the method includes the following steps: after step (S1) and before step (S7), the second clamping block 2 is fixedly connected to the rudder bearing seat 5, so that when the first gap is increased, only the attitude and position of the first pressure block and the connecting rod 3 need to be adjusted. Specifically, the second clamping block 2 can be temporarily welded to the rudder bearing seat 5.

[0055] Furthermore, the specific connection methods of fixed setting and fixed connection refer to the methods that can fix the relative positional relationship of two connected components, including fixing by connectors, fixing by welding, fixing by adhesive, fixing by integral molding, and fixing by snap-fit ​​connection.

[0056] Furthermore, detachable connection refers to the ability of two connected components to be repeatedly assembled and disassembled without damage or severe deformation, including fixing by connectors or by snap-fit ​​connections.

[0057] Furthermore, adjustable connection means that the two connected components can be adjusted in their relative positions before being fixed, and the aforementioned adjustment and fixing process can be repeated, including connection through elongated holes and connectors, and connection through sliding connection plus detachable connection.

[0058] Furthermore, the connectors include fasteners, straps, ropes, pneumatic connectors, hydraulic connectors, flanges, Velcro, and buttons.

[0059] In summary, the embodiments of the present invention provide a drilling device and a method for drilling holes in a rudder bearing seat 5 using the device, the technical effects of which are as follows:

[0060] In this invention, a first clamping block 1 and a second clamping block 2 are respectively provided on both sides of the rudder bearing seat 5 along the vertical direction. The two ends of the connecting rod 3 are adjustablely connected to the first clamping block 1 and the second clamping block 2, respectively, so that the size of the first gap between the first clamping block 1 and the second clamping block 2 is adjustable. Therefore, the first clamping block 1 and the second clamping block 2 can be clamped to both sides of the rudder bearing seat 5 along the vertical direction by reducing the first gap to fix the positions of the first clamping block 1 and the second clamping block 2. Furthermore, the drill base 41 of the drilling rig 4 is provided on the first clamping block 1, and the drill bit 42 of the drilling rig 4 is vertically arranged and faces the second clamping block 2 on the drill base 41 of the drilling rig 4, and has a second gap in the horizontal direction with the first clamping block 1, so that the drilling rig 4 can... Drilling is performed on the end face of the rudder bearing seat 5 on a pressure block; furthermore, after the first clamping block 1 and the second clamping block 2 are clamped to the rudder bearing seat 5, the position of the first clamping block 1 and the second clamping block 2 in the horizontal direction can be flexibly adjusted by increasing the first gap, thereby adjusting the position of the drill rig 4 in the horizontal direction. After the drill bit 42 of the drill rig 4 is aligned with the point to be drilled, the first gap is reduced to clamp the first clamping block 1 and the second clamping block 2 to the rudder bearing seat 5, fixing the position of the drill rig 4, so that the drill rig 4 can readjust the drilling position without being removed from the first clamping block 1; in summary, the present invention can conveniently process multiple mounting holes on the upper and lower end faces of the rudder bearing seat 5, and the processing efficiency is high.

[0061] The above description is only a preferred embodiment of the present invention.
