Description

Technical Field

[0001] This utility model relates to the field of parts processing technology, specifically a drilling device suitable for processing copper product parts. Background Technology

[0002] Copper component processing is a crucial link in the manufacturing industry, widely used in electronics, electrical engineering, machinery, and construction. Copper, due to its excellent electrical and thermal conductivity, corrosion resistance, and machinability, is an ideal material for manufacturing precision components. The processing involves multiple steps, including cutting, stamping, bending, welding, and drilling, requiring strict control over dimensional accuracy, surface quality, and mechanical properties to meet the needs of various applications. Drilling is a key step in copper component processing, especially for high-precision or complex structural parts, where pre-drilling is particularly important. Pre-drilling involves drilling a guide hole with a smaller diameter and appropriate depth before the actual drilling. Its core functions are threefold: first, precise positioning, using a center punch, scribing, or drill jig to determine the hole position and prevent deviation during the actual drilling; second, guiding the drill bit, providing an initial path for the drill bit and preventing skewing or vibration caused by uneven cutting forces, especially suitable for deep hole or thin-walled parts; and third, reducing deformation, as step-by-step drilling reduces the amount of material cut per pass, minimizing heat accumulation and cutting force impact, thereby controlling the elastic or plastic deformation of the copper material.

[0003] Before drilling, copper product parts that have undergone pre-drilling require the guide hole to be vertically aligned with the drill bit of the drilling machine to ensure precise positioning during drilling. However, in existing traditional processing, guide hole positioning relies entirely on manual marking, visual alignment, or measurement with a simple ruler by workers. This not only heavily depends on skilled workers but is also prone to positioning errors due to visual fatigue or hand-eye coordination deviations. Especially for small guide holes with a diameter of less than 5mm, manual alignment errors often exceed 0.5mm, directly causing drilling misalignment and scrapping of parts. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a drilling device suitable for processing copper product accessories, which solves the problem of positioning errors caused by manual visual alignment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drilling device suitable for processing copper product accessories, including a worktable, a gantry-shaped mounting frame on the worktable, a drilling machine body installed in the middle of the top surface of the gantry-shaped mounting frame, an accessory to be processed placed directly below the drilling machine body, electric telescopic rods symmetrically arranged on the left and right sides of the worktable, the telescopic ends of the electric telescopic rods are set inward and a clamping base plate is installed at the end, left and right limiting components are arranged on the inner side of the clamping base plate, a guide hole is opened on the accessory to be processed, and a laser positioner for positioning the guide hole is installed on the left side of the drilling machine body.

[0006] Furthermore, the left and right limiting components include a limiting base, with L-shaped sliding blocks symmetrically arranged at both ends of the limiting base. The short end of the L-shaped sliding block is set downward and slidably disposed inside the limiting base. The long end of the L-shaped sliding block extends to provide a clamping block, which fits against the inner side of the limiting base. A connecting post extends from the top surface of the L-shaped sliding block. The limiting base has a sliding groove for the L-shaped sliding block and the connecting post to slide back and forth. A fixing screw is threaded to the top surface of the connecting post. A hand-tightening block is provided on the top surface of the fixing screw. A friction pad is provided on the outer side of the bottom surface of the hand-tightening block. A friction coating that cooperates with the friction pad is provided on the top surface of the limiting base.

[0007] Furthermore, the left and right limiting components are detachable structures, and the limiting base and the clamping base plate are fixedly connected by bolts.

[0008] Furthermore, positioning blocks are symmetrically arranged at both the front and rear ends of the inner side of the clamping base plate, and positioning grooves for accommodating the positioning blocks are opened on the outer side of the limiting base.

[0009] Furthermore, a clamping pad layer is provided on the inner side of the clamping block.

[0010] Furthermore, the top surface of the limiting base has distance markings on the outside of the friction coating.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The precise alignment of the laser positioner with the guide hole replaces traditional manual visual alignment or mechanical scribing, avoiding visual errors or operational deviations caused by manual operation. The electric telescopic rod and left / right limit components enable precise positional adjustment of the workpiece in both left / right and front / back directions. The detachable left / right limit components allow for replacement with appropriate components based on the shape or size of the copper parts, eliminating the need to replace the entire equipment and reducing tooling costs for multi-variety production. The positioning block and positioning groove ensure quick alignment when replacing limit components, reducing assembly time. The clamping pad disperses clamping force through elastic deformation, preventing damage to the copper surface. Distance scales provide intuitive numerical references for adjusting the front / back position of the L-shaped sliding block, allowing operators to quickly determine the position without additional measuring tools.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] like Figures 1 to 3 As shown, a drilling device suitable for processing copper product accessories includes a workbench 1, a gantry-type mounting frame 2 on the workbench 1, a drilling machine body 3 mounted in the middle of the top surface of the gantry-type mounting frame 2, a part to be processed 4 placed directly below the drilling machine body 3, electric telescopic rods 5 symmetrically arranged on the left and right sides of the workbench 1, the telescopic ends of the electric telescopic rods 5 are set inward and the ends are equipped with clamping base plates 501, left and right limiting components 6 are arranged inside the clamping base plates 501, a guide hole 401 is opened on the part to be processed 4, and a laser positioner 7 for positioning the guide hole 401 is installed on the left side of the drilling machine body 3.

[0016] like Figure 1 As shown, the main improvement of this utility model lies in solving the problem of positioning error caused by manual visual alignment, such as... Figures 1 to 3As shown, this utility model discloses a drilling device suitable for processing copper product accessories. Before starting processing, a suitable left and right limiting components 6 are selected according to the shape of the accessory 4 to be processed. During installation, the positioning block 502 and the positioning groove 610 are aligned to ensure that the limiting base 601 is not offset and that the baseline of the distance scale 612 is consistent with the positioning baseline of the clamping base plate 501, laying a precision foundation for subsequent adjustments. Then, according to the size of the accessory 4 to be processed and the position of the guide hole 401, the distance scale 612 on the top surface of the limiting base 601 is observed. The L-shaped sliding block 602 is manually pushed to move back and forth along the sliding groove 605, driving the clamping block 603 to adjust synchronously until the distance scale 612 shows that the position of the clamping block 603 matches the side limiting requirements of the accessory. After adjustment, turn the hand-tightening block 607 clockwise to tighten the fixing screw 606 downwards along the connecting column 604. This causes the friction pad 608 on the bottom of the hand-tightening block 607 to press tightly against the friction coating 609 of the limiting base 601, locking the L-shaped sliding block 602 through friction to prevent displacement during processing. This completes the adjustment of the left and right limiting components 6. Then, place the workpiece 4 to be processed between the clamping blocks 603 and control the electric telescopic rod 5. Its telescopic end pushes the clamping base plate 501 inwards, causing the left and right limiting components 6 to move synchronously towards the workpiece 4 until the clamping pads 611 of the clamping blocks 603 on both sides are tightly against the sides of the workpiece 4. Next, turn on the laser positioner 7 and extend and retract the electric telescopic rod 5 back and forth to observe whether the laser spot is accurately projected onto the center of the guide hole 401. After vertical alignment, control the electric telescopic rod 5 to move a fixed distance to the right. The fixed distance is equivalent to the horizontal projection distance between the drill bit position of the drilling machine body 3 and the laser positioner 7. At this time, control the drilling machine body 3 to start working, and the drilling work can be completed.

[0017] like Figures 1 to 3 As shown, the left and right limiting components 6 include a limiting base 601. L-shaped sliding blocks 602 are symmetrically arranged at the front and rear ends of the limiting base 601. The short ends of the L-shaped sliding blocks 602 are set downward and slidably disposed inside the limiting base 601. A clamping block 603 extends from the long end of the L-shaped sliding blocks 602 and fits against the inner side of the limiting base 601. A connecting post 604 extends from the top surface of the L-shaped sliding blocks 602. The limiting base 601 has a sliding groove 605 for the L-shaped sliding blocks 602 and the connecting post 604 to slide back and forth. A fixing screw 606 is threadedly connected to the top surface of the connecting post 604. A hand-tightening block 607 is provided on the top surface of the fixing screw 606. A friction pad 608 is provided on the outer side of the bottom surface of the hand-tightening block 607. A friction coating 609 that cooperates with the friction pad 608 is provided on the top surface of the limiting base 601.

[0018] Specifically, before processing begins, the limiting base 601 of the left and right limiting components 6 is fixed to the clamping base plate 501 with bolts, and the baseline of the distance scale 612 is aligned with the positioning baseline of the clamping base plate 501, laying a precision foundation for subsequent adjustments. Then, based on the dimensions of the part to be processed 4 and the position of the guide hole 401, the distance scale 612 on the top surface of the limiting base 601 is observed. The L-shaped sliding block 602 is manually pushed, moving back and forth along the sliding groove 605, causing the clamping block 603 to adjust synchronously until the distance scale 612 indicates that the position of the clamping block 603 matches the side limiting requirements of the part. After adjustment, the hand-tightening block 607 is turned clockwise, causing the fixing screw 606 to tighten downwards along the connecting column 604, so that the friction pad 608 on the bottom surface of the hand-tightening block 607 presses tightly against the friction coating 609 of the limiting base 601. This friction locks the L-shaped sliding block 602, preventing displacement during processing, thus completing the adjustment of the left and right limiting components 6.

[0019] like Figure 2 and Figure 3 As shown, the left and right limiting components 6 are detachable structures, and the limiting base 601 and the clamping base plate 501 are fixedly connected by bolts.

[0020] Specifically, by setting up detachable left and right limit components 6, the corresponding limit components can be replaced according to the shape or size of the copper fittings, without replacing the entire set of equipment, thus reducing tooling costs for multi-variety production. At the same time, when the left and right limit components 6 are worn, they can be disassembled and replaced individually, without the need to repair the entire workbench 1 or clamping base plate 501, reducing downtime and maintenance costs.

[0021] like Figure 2 and Figure 3 As shown, positioning blocks 502 are symmetrically arranged at the front and rear ends of the inner side of the clamping base plate 501, and a positioning groove 610 for accommodating the positioning blocks 502 is opened on the outer side of the limiting base 601.

[0022] Specifically, by setting a positioning block 502 on the inner side of the clamping base plate 501, and providing a corresponding positioning groove 610 on the outer side of the limiting base 601, quick alignment can be achieved when replacing the left and right limiting components 6, avoiding deviations caused by manual alignment and reducing assembly time. Furthermore, the cooperation of the positioning block 502 and the positioning groove 610 ensures that left and right limiting components 6 of the same model can still be installed in the same reference position after multiple disassemblies, ensuring consistent positioning parameters for parts processed in different batches.

[0023] like Figure 3 As shown, a clamping pad layer 611 is provided on the inner side of the clamping block 603.

[0024] Specifically, by providing a clamping pad 611 inside the clamping block 603, the friction of the pad is greater than that of the metal contact surface, which can prevent the copper fittings from slipping slightly due to rotational force or vibration during drilling, further ensuring the drilling position accuracy. At the same time, because copper is relatively soft, traditional metal clamping parts are prone to surface scratches, while the clamping pad 611 can disperse the clamping force through elastic deformation, avoiding damage to the copper surface.

[0025] like Figure 3 As shown, the top surface of the limiting base 601 has a distance scale 612 on the outside of the friction coating 609.

[0026] Specifically, by setting a distance scale 612 on the top surface of the limiting base 601, an intuitive numerical reference can be provided for adjusting the front and rear positions of the L-shaped sliding block 602, allowing operators to quickly determine the position without additional measuring tools. At the same time, the guide holes 401 of the same batch of parts are in the same position, and the adjustment parameters of the L-shaped sliding block 602 can be directly recorded through the distance scale 612, which can be reused in subsequent workpieces, reducing repeated measurements and trial and error time.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
