Description

Technical Field

[0001] This invention belongs to the field of power construction tools technology, specifically relating to a drilling aid for power fittings and its usage method. Background Technology

[0002] Power fittings are key metal components connecting and assembling various devices in power systems. Before installation, drilling is often required based on site conditions. Power fittings function to transmit mechanical and electrical loads and provide protection. They can be categorized by function into suspension clamps, tension clamps, connecting fittings, protective fittings, equipment clamps, T-clamps, busbar fittings, and guy wire fittings. They can also be categorized by application into line fittings and substation fittings. Furthermore, power fittings are classified by product unit into malleable cast iron, forged, aluminum-copper, and cast iron types. Currently, drilling for power fittings mainly relies on operators using handheld electric drills with simple clamps and bench drills. For irregularly shaped or irregular fittings, it is difficult to quickly and accurately determine and fix the hole position, often relying on manual marking and alignment, which is time-consuming, labor-intensive, and prone to errors. Current simple clamps only clamp from one or both sides; during drilling, the fittings are easily affected by the axial and rotational forces of the drill bit, causing displacement, vibration, or even rotation, resulting in slight deviations in the hole position. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a drilling aid for power fittings and its usage method, thereby solving the technical problems mentioned in the background art.

[0004] The objective of this invention is achieved as follows: A drilling aid for power fittings includes a base, a plurality of columns fixedly mounted on the upper surface of the base, an operating platform fixedly mounted on the upper end of each column, and a debris collection system disposed between the operating platform and the base; an adaptive clamping and positioning mechanism is disposed on the upper surface of the operating platform, the adaptive clamping and positioning mechanism comprising: The first axial clamping assembly includes a first bidirectional lead screw arranged along the X-axis direction. A first sliding block is fitted on each of the two reverse threads of the first bidirectional lead screw. A first L-shaped clamping block is bolted to the top of each first sliding block. The two first L-shaped clamping blocks are arranged opposite to each other. The second axial clamping assembly includes a second bidirectional lead screw arranged along the Y-axis. The second bidirectional lead screw and the first bidirectional lead screw are located on the same horizontal plane and are spatially perpendicular. A second sliding block is fitted on each of the two reverse threads. A second L-shaped clamping block is bolted to the top of each second sliding block. The two second L-shaped clamping blocks are arranged opposite to each other.

[0005] Two bidirectional lead screws, arranged perpendicularly to each other in the same plane, drive two pairs of opposing L-shaped clamping blocks to simultaneously and symmetrically clamp the workpiece in both the X and Y horizontal directions, achieving precise positioning and secure fixation of the workpiece in the horizontal plane. In use, the workpiece is placed on the working area (support plate) of the device. By driving the first and second bidirectional lead screws to rotate, the two pairs of L-shaped clamping blocks move simultaneously from two perpendicular directions towards the center of the workpiece until they are in close contact with the sides of the workpiece, thus completing the centering and clamping of the workpiece. The mechanical symmetrical drive ensures balanced clamping force, automatic centering, and high-precision drilling, avoiding minor deviations in hole position.

[0006] Furthermore, the upper surface of the operating table is provided with an X-guide groove and a Y-guide groove. The first bidirectional lead screw is disposed in the X-guide groove, and the second bidirectional lead screw is disposed in the Y-guide groove. A first drive motor is fixedly disposed at the left end of the X-guide groove and is connected to the left end of the first bidirectional lead screw. A second drive motor is fixedly disposed at the rear end of the Y-guide groove and is connected to the rear end of the second bidirectional lead screw. Two horizontal guide rods extending along the length direction of the X-guide groove are fixedly disposed in the X-guide groove, and two vertical guide rods extending along the length direction of the Y-guide groove are fixedly disposed in the Y-guide groove. The first sliding block is slidably connected to the horizontal guide rods, and the second sliding block is slidably connected to the vertical guide rods.

[0007] Both the first and second drive motors are servo motors, providing rotational power that is transmitted to the bidirectional lead screw via a coupling. The rotational motion of the lead screw is converted into the linear motion of the sliding blocks through a threaded joint. The horizontal and vertical guide rods form a sliding joint, eliminating the circumferential rotational freedom of the sliding blocks during movement, ensuring that the sliding blocks and their clamping blocks move smoothly in a straight line only along a preset X or Y direction, greatly improving the accuracy and stability of the motion. In use, the electronic control device sends a command, the first drive motor starts, and drives the first bidirectional lead screw to rotate. Under the constraint of the horizontal guide rod, the two first sliding blocks overcome the threaded friction with the lead screw and make precise, non-rotational linear movements in opposite or opposite directions along the X-axis. The Y-axis movement is similar.

[0008] Furthermore, a first clamping plate is fixedly connected to the upper end of the first L-shaped clamping block, and a plurality of transverse clamping springs are fixedly arranged on the inner plate surface of the first clamping plate; a second clamping plate is fixedly connected to the upper end of the second L-shaped clamping block, and a plurality of longitudinal clamping springs are fixedly arranged on the inner plate surface of the second clamping plate. The transverse clamping springs are used to provide adaptive clamping force to the power fitting from the transverse direction, and the longitudinal clamping springs are used to provide adaptive clamping force to the power fitting from the longitudinal direction.

[0009] By incorporating multiple rows of springs (lateral / longitudinal clamping springs) on the inner side of the clamping plate (the surface in contact with the workpiece), the original rigid contact is transformed into a combination of rigid drive and elastic contact. The springs deform under compression, automatically compensating for unevenness, burrs, or minor dimensional differences on the workpiece side caused by casting, machining, or other factors. In use, as the L-shaped clamping block moves towards the workpiece under the drive of the lead screw, the springs on the clamping plate first contact the workpiece surface. As the clamping block continues to advance, the springs are compressed, and the resulting elastic force acts evenly on localized areas of the workpiece side. Even if the workpiece side is not perfectly flat, the multiple rows of springs can deform independently, ensuring that the workpiece is effectively and gently clamped at multiple points. Spring buffering avoids the pressure marks or scratches that rigid clamping might cause to the workpiece surface, making it particularly suitable for processing metal blanks with low surface precision. Simultaneously, the more uniform distribution of elastic force effectively prevents workpiece tilting caused by localized high points.

[0010] Furthermore, a gantry frame is fixedly installed on the upper surface of the operating table, a horizontal plate is fixedly installed at the upper end of the gantry frame, a linear drive is fixedly installed on the horizontal plate, and a bench drill with a downward drill bit is fixedly installed at the lower end of the linear drive; the linear drive is a cylinder or an electric push rod.

[0011] A linear drive (cylinder / electric actuator) serves as the feed power source, driving the bench drill (or electric spindle) to complete the vertical feed and retraction movements. The bench drill provides the spindle rotation cutting motion required for drilling. The combination of these three elements enables drilling of electric fittings. In operation, after the workpiece is clamped and positioned, the electronic control device starts the bench drill spindle to rotate, simultaneously controlling the extension of the linear drive to push the rotating drill bit downwards to complete the drilling. After drilling is complete, the linear drive retracts, lifting the drill bit away from the workpiece. This achieves integrated automation of clamping and drilling, eliminating the need for manual operation of the electric drill and improving processing quality and efficiency.

[0012] Furthermore, the upper surface of the operating table is fixedly provided with multiple support legs, and the upper end of the support legs is fixedly provided with a bearing plate. The bearing plate has a hollow cavity structure inside, and the upper surface of the bearing plate has multiple through holes that communicate with the hollow cavity structure. The through holes are used for chip removal.

[0013] The support plate is suspended above the worktable by support legs. Its interior is hollow, and its upper surface is covered with through holes. This structure makes the support plate not only a workpiece placement platform but also a screen chip removal platform. Drilling debris falls directly into the cavity below through the through holes, achieving initial and immediate chip separation and preventing debris accumulation on the worktable surface, thus avoiding any impact on the flatness of the workpiece placement.

[0014] Furthermore, the debris collection system includes multiple conduits connected to the cavity structure. A collection chamber is provided between the operating table and the base. A vacuum pump is installed inside the collection chamber to generate negative pressure inside the collection chamber. The upper end of the conduit is connected to the cavity structure of the support plate, and the lower end of the conduit is connected to the collection chamber. An observation port with transparent glass is provided on the side wall of the collection chamber. A debris collection drawer is provided at the bottom of the collection chamber. A removable filter basket is provided inside the debris collection drawer, and a handle is fixedly provided on the side wall of the debris collection drawer.

[0015] A vacuum pump serves as the power source, generating negative pressure (vacuum) within the sealed collection chamber. This negative pressure is transmitted to the cavity of the support plate via a conduit. Under the influence of this pressure difference, debris falling into the support plate is drawn in by the airflow, transported through the conduit to the collection chamber, and finally settles in the debris collection drawer. An observation port and filter basket facilitate observation and cleaning. This significantly improves the working environment, eliminating the health hazards of metal dust and flying debris to operators and preventing contamination of workshop equipment.

[0016] Furthermore, an electrical control device is fixedly installed on the upper surface of the operating table. The electrical control device is an electrical control box with an integrated PLC (Programmable Logic Controller). The electrical control device is electrically connected to the linear drive and the bench drill, the first drive motor and the second drive motor, and the vacuum pump.

[0017] The PLC-based electrical control unit acts as the brain of the entire equipment, coordinating and controlling the sequence, timing, and logic of all electric and pneumatic actuators (drive motors, linear drives, bench drills, and vacuum pumps). During operation, the operator starts the machining program via the control unit's panel. The PLC sends instructions sequentially or simultaneously according to a preset program: controlling the clamping motor for positioning and clamping, starting the vacuum pump, starting the bench drill and controlling the linear drive for drilling, retracting the drill bit and stopping the drill after drilling, controlling the clamping motor to reverse and release the workpiece, and optionally delaying the vacuum pump's stop. The entire process is automated and programmed. Integrating multiple separate actions (clamping, drilling, and chip removal) into a continuous automated process significantly reduces operational difficulty and labor intensity.

[0018] Furthermore, there are four uprights, which are fixedly installed at the four corners of the base and are arranged in a rectangular shape. There are also four cylindrical support legs, which are also arranged in a rectangular shape.

[0019] A method of using a drilling aid for electrical fittings, comprising the following steps: Place the power fitting workpiece on the support plate for rough positioning; The first and second bidirectional lead screws are controlled to rotate by an electronic control device, which drives the two first L-shaped clamping blocks and the two second L-shaped clamping blocks to approach and press against the side of the workpiece from the X and Y directions, respectively, thus completing the horizontal positioning and clamping. The linear drive and bench drill are started by the electronic control device, so that the drill bit of the bench drill moves downward while rotating, and drills a hole in the upper surface of the workpiece from the vertical direction. The vacuum pump is started by the electronic control device to create negative pressure inside the collection chamber. During the drilling operation, the debris is collected into the debris collection drawer through the guide tube. After the drilling is completed, the drill bit is raised, the linear drive is reset, and the first and second bidirectional lead screws are rotated in opposite directions to remove the power fitting workpiece.

[0020] The beneficial effects of this invention are as follows: By using two bidirectional lead screws arranged perpendicularly to each other in the same plane, two pairs of opposing L-shaped clamping blocks are driven to simultaneously and symmetrically clamp the workpiece in both the X and Y horizontal directions, achieving precise positioning and firm fixation of the workpiece in the horizontal plane. In use, the workpiece is placed on the working area (bearing plate) of the device. By driving the first and second bidirectional lead screws to rotate, the two pairs of L-shaped clamping blocks move simultaneously from two perpendicular directions towards the center of the workpiece until they are in close contact with the sides of the workpiece, thus completing the centering and clamping of the workpiece. The mechanical symmetrical drive ensures balanced clamping force, automatic centering, and high-precision drilling, avoiding minor deviations in hole position. Clamping, drilling, and debris collection can all be controlled by a central electronic control device with one button or a programmed sequence, reducing manual intervention, lowering labor intensity, and improving work efficiency and consistency. The debris collection system can suck away the debris generated during drilling through the through-holes in the bearing plate and collect it in a debris drawer, keeping the operating area clean, improving the working environment, and eliminating safety hazards.

A second L-shaped clamping block 9 is bolted to the top of each second sliding block 8, and the two second L-shaped clamping blocks 9 are arranged opposite each other.

[0027] Two bidirectional lead screws, arranged perpendicularly to each other in the same plane, drive two pairs of opposing L-shaped clamping blocks to simultaneously and symmetrically clamp the workpiece in both the X and Y horizontal directions, achieving precise positioning and secure fixation of the workpiece in the horizontal plane.
