Description

Technical Field

[0001] This invention relates to the field of drilling technology, and in particular to a grooved wire clamp, a positioning drilling device for production, and a method of use thereof. Background Technology

[0002] In power line construction, parallel groove clamps are used to connect and secure cables. However, existing parallel groove clamps are prone to loosening between the two upper clamps when holding cables, affecting the stability of the cable connection. Simultaneously, exposed bolts are susceptible to corrosion along with the nut rings, leading to difficulties in later disassembly. Furthermore, during the production process of parallel groove clamps, traditional equipment is inaccurate in positioning when drilling holes in the lower and upper clamps, resulting in deviations in drilling positions and affecting product quality. Moreover, the debris generated during drilling is difficult to collect, potentially impacting the working environment and personnel. Summary of the Invention

[0003] The purpose of this invention is to solve the shortcomings of existing parallel groove clamps, such as easy loosening, easy corrosion of bolts, inaccurate positioning of drilling equipment, and difficulty in collecting debris. This invention proposes a parallel groove clamp, its production positioning drilling equipment, and its usage method.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A parallel groove cable clamp includes a lower clamp plate and two upper clamp plates. Bolts are installed on both upper clamp plates. Two nut rings are fixed to the bottom of the lower clamp plate. The bottom ends of the two bolts pass through the lower clamp plate and are threaded to the two nut rings respectively. The clamp is used to hold the cable through the lower clamp plate and the upper clamp plates.

[0006] Both ends of the bottom of the two upper clamping plates are provided with semi-circular grooves I, and both sides of the top of the lower clamping plate are provided with semi-circular grooves II. The semi-circular grooves II and semi-circular grooves I cooperate to limit and clamp the cable. The inner walls of the semi-circular grooves II and I are fixed with multiple arc-shaped strips I to increase the friction between the semi-circular grooves II and I and the cable.

[0007] It also includes a snap-fit ​​structure set in the two upper clamps, which is used to ensure the stability between the two upper clamps when the two upper clamps cooperate with the lower clamp to clamp the cable. The snap-fit ​​structure includes an arc-shaped strip II and a cavity, and the arc-shaped strip II is fixed to one end of one of the upper clamps, and the cavity is set inside the other upper clamp.

[0008] In one possible design, the snap-fit ​​structure further includes a lifting platform slidably connected to the cavity. Multiple sliding rods are fixed to both sides of the bottom of the lifting platform. The bottom ends of the multiple sliding rods extend slidably into corresponding semi-circular grooves I. A ball is fixed to the bottom end of each of the multiple sliding rods. Two trapezoidal sliders are slidably connected to the top inner wall of the cavity. One end of each trapezoidal slider extends to one side of an upper clamping plate and is fixed with a snap-fit ​​strip, which cooperates with an arc-shaped strip II to complete the snap-fit ​​between the two upper clamping plates. Two fixed bases are fixed to the top inner wall of the cavity. One side of each fixed base is fixed with a tension spring via a spring seat. One end of each tension spring is fixedly connected to one end of a corresponding trapezoidal slider via a spring seat, for driving the trapezoidal slider to move and reset into the cavity. A guide wheel is rotatably provided on the top side of the lifting platform, and the guide wheel cooperates with the inclined surface of the trapezoidal slider to push the trapezoidal slider outward when the lifting platform moves upward.

[0009] When the cable is clamped on another upper clamping plate, the ball abuts against the cable and pushes the slide bar and the lifting platform to move up. The guide wheel on one side of the lifting platform cooperates with the inclined surface of the trapezoidal slider to drive the trapezoidal slider to move outward. The buckle strip at one end of the trapezoidal slider cooperates with the arc strip II on one side of the adjacent upper clamping plate to complete the positioning between the two adjacent upper clamping plates and ensure the stability of the two upper clamping plates.

[0010] In one possible design, a protective bellows is fixed to the bottom of the nut ring, and a disc is fixed to the bottom end of the protective bellows. The bottom end of the bolt abuts against the top of the disc, which is used to protect the bolt extending below the lower clamping plate and prevent corrosion between the bolt and the nut ring.

[0011] In one possible design, the top of the upper clamping plate is provided with an isolation plate, and the bottom end of the bolt passes through the isolation plate to increase the pressure applied by the bolt to the upper clamping plate when the bolt moves downward. The outer wall of the bolt is fitted with a rubber washer and a rubber liner, with the rubber washer located above the upper clamping plate and the rubber liner located between the lower clamping plate and the upper clamping plate. The top of the lower clamping plate is fixed with two guide shafts, and the top ends of the two guide shafts slide into the corresponding upper clamping plate to constrain the downward movement of the upper clamping plate when the bolt moves the upper clamping plate downward.

[0012] A positioning drilling device is used to drill holes in the lower and upper clamping plates of the above-mentioned parallel groove clamp. It includes a base plate, a movable worktable is slidably provided on the top of the base plate for supporting the workpiece to be drilled, a support plate is fixed on one side of the top of the base plate, and a drill chuck is provided on one side of the support plate for drilling the workpiece.

[0013] A movable structure, set on a base plate, is used to enable the drill chuck to drill holes at different positions on the workpiece. The movable structure includes a slide groove set on the top of the base plate and a lead screw rotatably connected in the slide groove.

[0014] A positioning drilling structure is set above the movable worktable to automatically position the workpiece before drilling. The positioning drilling structure includes two positioning rollers, and the outer diameter of the positioning rollers matches the inner diameter of the semi-circular groove II.

[0015] In one possible design, the moving structure further includes a nut slider slidably connected in a groove, the nut slider being threadedly connected to a lead screw, the nut slider being fixed to the bottom of the moving worktable, the top of the moving worktable being provided with a discharge groove corresponding to the position of the drill chuck, for making way for the drill bit and collecting debris when the drill chuck passes through the drill bit to drill a hole, and a T-shaped guide block being fixed on one side of the top of the moving worktable, and a T-shaped electromagnet being fixedly embedded on one side of the T-shaped guide block for magnetically attracting the workpiece;

[0016] When the T-shaped electromagnet is energized, the lower clamping plate is attracted to one side of the T-shaped guide block. The screw rotates and drives the moving worktable to move linearly through the nut slider, moving the lower clamping plate to the bottom of the drill chuck for drilling.

[0017] In one possible design, the positioning drilling structure further includes a vertical slot on one side of the support plate, a threaded rod rotatably connected longitudinally within the vertical slot, a sliding seat slidably connected to the threaded rod within the vertical slot, an upper slide plate fixed to one side of the sliding seat, a drill chuck rotatably connected to the bottom of the upper slide plate, multiple guide rods slidably passing through the upper slide plate, the bottom ends of the multiple guide rods being fixed to the same lower slide plate, multiple elastic springs abutting against the upper and lower slide plates via spring seats, and the elastic springs being sleeved on the outer walls of the guide rods, two positioning rollers rotatably connected to the bottom of the lower slide plate via bases, and the two positioning rollers being located on both sides of the drill chuck, and a circular hole provided in the lower slide plate for clearance of the drill bit clamped in the drill chuck;

[0018] The rotation of the threaded rod causes the sliding seat to move downwards, which in turn causes the upper and lower sliding plates to move downwards as a whole. The two positioning rollers at the bottom of the lower sliding plate extend into the two semi-circular grooves I. Since the outer diameter of the positioning rollers matches the inner diameter of the semi-circular grooves I, the positioning rollers position the lower clamping plate, so that the drill chuck is located at the center line of the lower clamping plate. As the upper and lower sliding plates move downwards, the upper sliding plate compresses the elastic spring, and the positioning rollers clamp the lower clamping plate under the action of the elastic spring. The upper sliding plate also causes the drill chuck to move downwards, drilling a hole in the lower clamping plate.

[0019] In one possible design, protective corrugated strips I are fixed on both sides of the nut slider. The two protective corrugated strips I, with their ends facing away from each other, are fixedly connected to the inner walls of the two sides of the slide groove, respectively. The width of the protective corrugated strips I matches the width of the slide groove and is used to protect the lead screw. Corrugated tubes I are fixed on the top and bottom inner walls of the vertical groove. The two corrugated tubes I, with their ends facing each other, are fixedly connected to the top and bottom of the sliding seat, respectively. The corrugated tubes I are sleeved on the outer wall of the threaded rod and are used to protect the threaded rod. Corrugated tubes II are fixed between the upper and lower sliding plates, and the drill chuck, elastic spring, and guide rod are all located inside the corrugated tubes II and are used to protect the drill chuck, elastic spring, and guide rod.

[0020] In one possible design, an auger is rotatably connected inside the discharge trough to discharge the debris collected in the discharge trough to the outside. A baffle plate is slidably connected to the top of the movable worktable. A protective corrugated strip II is fixed to the side of the baffle plate away from the T-shaped guide block. The end of the protective corrugated strip II away from the baffle plate is fixed to the top of the movable worktable. A magnetic strip is fixedly embedded on the side of the baffle plate away from the protective corrugated strip II to magnetically attract the baffle plate to one side of the workpiece.

[0021] When the drill chuck is drilling, the debris generated falls into the discharge chute. The auger rotates to discharge the debris. The baffle plate is attracted to one side of the lower and upper clamping plates by the magnetic attraction of the magnetic strip, which prevents the auger from being exposed to the outside and causing injury to the workers. The movement of the baffle plate can also scrape away the debris on the moving worktable.

[0022] The method of using the positioning drilling equipment in this application includes the following steps:

[0023] S1. Workpiece placement and electromagnetic adsorption: Place the lower clamping plate or the upper clamping plate on the movable worktable, with the lower clamping plate placed with the two semi-circular grooves facing upwards and the upper clamping plate placed with the two semi-circular grooves facing downwards. Then, start the electromagnet to energize it and adsorb the workpiece onto one side of the guide block.

[0024] S2. Worktable movement and positioning: The motor drives the lead screw to rotate, and the lead screw and nut slider are threaded together, which drives the moving worktable to move linearly and move the workpiece to the bottom of the drill chuck to prepare for drilling.

[0025] S3. Positioning Roller Lowering and Workpiece Clamping: The motor drives the threaded rod to rotate, which is threadedly connected to the sliding seat. This causes the sliding seat to move the upper and lower slide plates downwards as a whole. The positioning rollers at the bottom of the lower slide plate are positioned according to the type of workpiece. For the lower clamping plate, the positioning rollers extend into its semi-circular groove, and center positioning is achieved by matching the outer diameter with the inner diameter of the groove. For the upper clamping plate, the positioning rollers abut against the arc surfaces on both sides of the workpiece to achieve center positioning. At the same time, the upper slide plate compresses the elastic spring, so that the positioning rollers clamp the workpiece under the action of the elastic spring.

[0026] S4. Drill bit movement and drilling operation: The upper slide plate continues to move downward, driving the drill chuck downward to drill the workpiece;

[0027] S5. Debris Discharge and Safety Protection: During the drilling process, the generated debris falls into the discharge chute. The auger is driven by a motor to rotate and discharge the debris to one side for collection. At the same time, the baffle plate is attracted to one side of the workpiece by the magnetic strip, preventing the auger from being exposed and causing safety hazards.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] In this invention, multiple sliding rods are fixed on both sides of the bottom of the lifting platform. The bottom ends of the multiple sliding rods slide into the corresponding semi-circular groove I. One end of each of the two trapezoidal sliders is fixed with a buckle strip. A guide wheel is rotatably provided on the top of one side of the lifting platform. When the other upper clamping plate clamps the cable, the ball abuts against the cable and pushes the lifting platform upward. The guide wheel on one side of the lifting platform cooperates with the inclined surface of the trapezoidal slider to drive the trapezoidal slider to move outward. The buckle strip at one end of the trapezoidal slider cooperates with the arc strip II on one side of the adjacent upper clamping plate to complete the positioning between the two adjacent upper clamping plates and further ensure the stability of the two upper clamping plates. This increases stability when clamping two cables and avoids loosening.

[0030] In this invention, a protective bellows is fixed to the bottom of the nut ring, and a disc is fixed to the bottom end of the protective bellows. The bottom end of the bolt abuts against the top of the disc. This is used to protect the bolt extending to the bottom of the lower clamping plate, so as to prevent corrosion between the bolt and the nut ring, which would affect the separation of the lower clamping plate and the upper clamping plate later.

[0031] In this invention, the drill chuck rotates at the bottom of the upper slide plate, and multiple guide rods slide through the upper slide plate. The bottom ends of the multiple guide rods are fixed to the same lower slide plate. Multiple elastic springs abut against the upper and lower slide plates through spring seats. Both positioning rollers rotate at the bottom of the lower slide plate through the base. The sliding seat drives the upper and lower slide plates to move downward as a whole. The two positioning rollers at the bottom of the lower slide plate extend into two semi-circular grooves I, which can position the lower clamping plate so that the drill chuck is located at the center line of the lower clamping plate. As the upper and lower slide plates move downward, the positioning rollers clamp the lower clamping plate under the action of the elastic springs, and the drill chuck can drill a hole in the lower clamping plate.

[0032] In this invention, an auger is rotatably connected inside the discharge trough, and a baffle plate is slidably connected to the top of the movable workbench. A protective corrugated belt II is fixed to one side of the baffle plate, and one end of the protective corrugated belt II is fixed to the top of the movable workbench. A magnetic strip is fixedly embedded on one side of the baffle plate. During the drilling process, the generated debris falls into the discharge trough. Then, the auger is driven by a motor to rotate, and the auger discharges the debris in the discharge trough to one side for easy collection later. In addition, when the lower or upper clamping plate is placed on the movable workbench for positioning and drilling, the baffle plate is attracted to one side of the lower or upper clamping plate by the magnetic attraction of the magnetic strip. Therefore, it is convenient for the auger to discharge debris later, and it can also prevent the auger from being exposed to the outside and causing injury to the workers.

[0033] In this invention, the snap-fit ​​structure in the parallel groove clamp makes the two upper clamping plates more stable and prevents them from loosening when clamping cables; the protective corrugated pipe and disc prevent the bolts and nuts from rusting and facilitate disassembly later; in the positioning drilling equipment, the positioning roller can accurately position the lower clamping plate so that the drill chuck can drill in the correct position; the auger can discharge drilling debris in time and facilitate collection; the baffle plate is attracted to one side of the workpiece under the action of the magnetic strip, which not only facilitates the discharge of debris, but also prevents the auger from being exposed and causing injury, and can also scrape debris off the worktable, ensuring the safety of the working environment and personnel.

[0046] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0047] In one embodiment: Refer to Figures 1-5 A type of parallel groove clamp includes components such as a lower clamping plate 1, two upper clamping plates 2, bolts 5, nut rings 21, snap-fit ​​structure, protective corrugated pipe 22, isolation plate 3, rubber gaskets 4, rubber pads 6, and guide shaft 7.

[0048] Reference Figures 1-3The lower clamp 1 has a "mountain" shaped structure, with symmetrical semi-circular grooves II8 on both sides of its top. Multiple arc-shaped strips I9 are evenly distributed on the inner wall of each semi-circular groove II8. The curvature of each arc-shaped strip I9 matches the curvature of the semi-circular groove II8, and the height of each arc-shaped strip I9 is ​​2-5mm, the width is 1-3mm, and the spacing between adjacent arc-shaped strips I9 is ​​3-8mm. These arc-shaped strips I9 increase the friction between the semi-circular groove II8 and the cable, preventing the cable from sliding within the cable clamp. Two nut rings 21 are fixed to the bottom of the lower clamp 1. The inner diameter of the nut rings 21 matches the outer diameter of the bolts 5. A protective corrugated tube 22, made of rubber, is fixed to the bottom of the nut rings 21, and a disc is fixed to its bottom end. The protective corrugated tube 22 protects the bolts 5 extending below the lower clamp 1, preventing corrosion between the bolts 5 and the nut rings 21, which would affect the subsequent separation of the lower clamp 1 and the upper clamp 2. Two guide shafts 7 are also fixed to the top of the lower clamping plate 1. The guide shafts 7 are cylindrical, and their height is determined according to the thickness of the upper clamping plate 2 and the installation requirements. The top ends of the two guide shafts 7 slide into the corresponding upper clamping plate 2. They are used to constrain the downward movement of the upper clamping plate 2 when the bolt 5 drives the upper clamping plate 2 to move downward, so as to ensure the stability and accuracy of the downward movement of the upper clamping plate 2.

[0049] Reference Figures 2-4 Both upper clamping plates 2 are semi-circular structures. Each upper clamping plate 2 has a bolt 5 passing through it. The bolt 5 is made of high-strength steel, and its length is determined according to the overall dimensions of the cable clamp. The bottom end of the bolt 5 passes through the lower clamping plate 1 and is threadedly connected to two nut rings 21. Rotating the bolt 5 adjusts the distance between the upper clamping plate 2 and the lower clamping plate 1, thus clamping the cable. Both ends of the bottom of the upper clamping plate 2 have semi-circular grooves I10, which cooperate with semi-circular grooves II8 to limit and clamp the cable. The inner wall of the semi-circular grooves I10 also has multiple evenly distributed arc-shaped strips I9, with the same specifications as the arc-shaped strips I9 in the semi-circular grooves II8. The top of the upper clamping plate 2 has an isolation plate 3, which is a rectangular flat plate made of insulating material such as rubber or plastic. The bottom end of the bolt 5 passes through the isolation plate 3. The isolation plate 3 increases the pressure exerted by the bolt 5 on the upper clamping plate 2 when the bolt 5 moves downward, improving the clamping effect on the cable. The outer wall of the bolt 5 is fitted with a rubber washer 4 and a rubber gasket 6. The rubber washer 4 is located above the upper clamping plate 2, and the rubber gasket 6 is located between the lower clamping plate 1 and the upper clamping plate 2. Both the rubber washer 4 and the rubber gasket 6 are made of rubber. They can play a role in buffering and sealing, preventing rainwater, dust and other substances from entering the inside of the parallel groove clamp, while reducing the friction between the bolt 5 and the upper clamping plate 2 and the lower clamping plate 1, thus extending the service life of the device.

[0050] Reference Figure 2 , Figure 4 and Figure 5The snap-fit ​​structure is installed inside the two upper clamping plates 2 to ensure stability between the two upper clamping plates 2 when they cooperate with the lower clamping plate 1 to clamp the cable. The snap-fit ​​structure includes an arc-shaped strip II 11, a cavity 12, a lifting platform 13, a slide rod 14, a ball 15, a trapezoidal slider 16, a fixed base 17, a tension spring 18, a snap-fit ​​strip 19, and a guide wheel 20. The arc-shaped strip II 11 is fixed to one end of one of the upper clamping plates 2. The cavity 12 is located inside the other upper clamping plate 2 and is rectangular in shape. Its dimensions are determined according to the installation requirements of the internal parts. The lifting platform 13 slides inside the cavity 12. Multiple slide rods 14 are fixed on both sides of the bottom of the lifting platform 13. The slide rods 14 are cylindrical, and the bottom ends of the multiple slide rods 14 slide into the corresponding semi-circular grooves I 10. A ball 15 is fixed to the bottom end of each of the multiple slide rods 14. Two trapezoidal sliders 16 are slidably connected to the top inner wall of cavity 12. The slope angle of the trapezoidal sliders 16 is 30°-60°. One end of each trapezoidal slider 16 extends to one side of the upper clamping plate 2 and is fixed with a snap-fit ​​strip 19. The shape of the snap-fit ​​strip 19 matches the arc-shaped strip II 11 to complete the snap-fit ​​between the two upper clamping plates 2. Two fixed bases 17 are fixed to the top inner wall of cavity 12. One side of each fixed base 17 is fixed with a tension spring 18 through a spring seat. The tension spring 18 is made of carbon spring steel wire with a wire diameter of 0.5-1.5mm, an outer diameter of 3-8mm, a free length of 10-20mm, and an initial tension of 2-8N. One end of each tension spring 18 is fixedly connected to one end of the corresponding trapezoidal slider 16 through a spring seat to drive the trapezoidal slider 16 to move and reset into cavity 12. A guide wheel 20 is rotatably provided on the top side of the lifting platform 13. The diameter of the guide wheel 20 is 5-10mm, and the cavity 12 cooperates with the inclined surface of the trapezoidal slider 16. It is used to push the trapezoidal slider 16 outward when the lifting platform 13 moves upward, so as to complete the clamping between two adjacent upper clamping plates 2.

[0051] A method of using a parallel groove clamp: Place two cables in the corresponding semi-circular grooves II8, then first tighten the bolt 5 in one of the upper clamping plates 2. The bolt 5 is threadedly connected to the nut ring 21, which drives the corresponding upper clamping plate 2 to move down. Through the two semi-circular grooves I10 at the bottom of the upper clamping plate 2, it cooperates with the semi-circular grooves II8 to complete the clamping operation of the two cables.

[0052] Tighten the bolt 5 inside the other upper clamping plate 2 to clamp the two cables again. When the other upper clamping plate 2 clamps the cables, the ball 15 abuts against the cables and pushes the slide bar 14 and the lifting platform 13 to move upward. The guide wheel 20 on one side of the lifting platform 13 cooperates with the inclined surface of the trapezoidal slider 16 to drive the trapezoidal slider 16 to move outward. The buckle strip 19 at one end of the trapezoidal slider 16 cooperates with the arc strip II 11 on one side of the adjacent upper clamping plate 2 to complete the positioning between the two adjacent upper clamping plates 2 and further ensure the stability of the two upper clamping plates 2. This increases the stability when clamping the two cables and avoids loosening. In addition, the movement of the baffle plate 45 can also scrape off the debris on the moving worktable 24.

[0053] Reference Figures 6-10 The positioning drilling equipment relates to the field of drilling technology and is used to drill holes in the lower clamping plate 1 and upper clamping plate 2 of the above-mentioned grooved wire clamp. It mainly includes components such as a base plate 23, a movable worktable 24, a support plate 32, a drill chuck 43, a movable structure, and a positioning drilling structure.

[0054] Reference Figure 6 and Figure 9 The base plate 23 is a rectangular flat plate structure, with a movable worktable 24 slidingly mounted on its top. The movable worktable 24 is used to support the workpiece to be drilled. A support plate 32 is welded to one side of the top of the base plate 23. The support plate 32 is a rectangular column structure, and its height is determined according to the drilling requirements. A drill chuck 43 is provided on one side of the support plate 32. The drill chuck 43 adopts an existing standard drill chuck structure and is used to drill holes in the workpiece.

[0055] Reference Figure 10The movable structure is mounted on the base plate 23 and is used to enable the drill chuck 43 to drill holes at different positions on the workpiece. The movable structure includes a slide groove 25 on the top of the base plate 23, a lead screw 26 rotating within the slide groove 25, and a nut slider 27 sliding within the slide groove 25. The slide groove 25 is a rectangular groove, the width and depth of which are determined according to the dimensions of the nut slider 27. The lead screw 26 is cylindrical, its length determined according to the length of the slide groove 25. One end of the lead screw 26 is rotatably connected to the inner wall of one end of the slide groove 25 via a bearing, and the other end extends to the outside of the base plate 23 and is connected to a drive motor. The drive motor is a servo motor, and its power is determined according to the load requirements of the drilling equipment. The nut slider 27 is a rectangular block structure with a threaded hole inside that matches the lead screw 26. The nut slider 27 is threadedly connected to the lead screw 26 and is fixed to the bottom of the movable worktable 24. The top of the movable worktable 24 is equipped with a discharge groove 31, which is a semi-circular groove and corresponds to the position of the drill chuck 43. This groove allows for clearance of the drill bit held in the drill chuck 43 and collects debris as the drill chuck 43 passes through it during drilling. A T-shaped guide block 29 is fixed to one side of the top of the movable worktable 24. The cross-section of the T-shaped guide block 29 is T-shaped, and its dimensions are determined according to the positioning requirements of the workpiece. It is used for positioning the workpiece. A T-shaped electromagnet 30 is fixedly embedded on one side of the T-shaped guide block 29. The attraction force of the T-shaped electromagnet 30 is determined according to the weight of the workpiece and the positioning requirements. It is used for magnetic attraction of the workpiece.

[0056] In actual operation, the T-shaped electromagnet 30 is first energized, generating magnetic force that attracts the lower clamping plate 1 to one side of the T-shaped guide block 29, achieving initial positioning of the lower clamping plate 1. Then, the drive motor is started, which drives the lead screw 26 to rotate. Since the nut slider 27 is threadedly engaged with the lead screw 26 and is fixed to the bottom of the movable worktable 24, the rotation of the lead screw 26 will drive the nut slider 27 to move linearly along the slide groove 25, thereby driving the movable worktable 24 to move linearly, moving the lower clamping plate 1 below the drill chuck 43, preparing for subsequent drilling.

[0057] Reference Figures 6-9The positioning drilling structure is positioned above the movable worktable 24 to automatically position the workpiece before drilling. The positioning drilling structure includes a vertical slot 33 on one side of the support plate 32, a threaded rod 34 rotatably connected to the vertical slot 33, a sliding seat 35 slidably connected to the vertical slot 33 and threadedly connected to the threaded rod 34, an upper slide plate 37 fixed to one side of the sliding seat 35, a drill chuck 43 rotating at the bottom of the upper slide plate 37, multiple guide rods 38 sliding through the upper slide plate 37, a single lower slide plate 40 fixed to the bottom of the multiple guide rods 38, multiple elastic springs 39 abutting between the upper slide plate 37 and the lower slide plate 40, and two positioning rollers 42 rotating at the bottom of the lower slide plate 40 via a base. The vertical slot 33 is a rectangular groove, the width and depth of which are determined according to the dimensions of the sliding seat 35. The threaded rod 34 is cylindrical, and its length is determined according to the length of the vertical slot 33. One end of the threaded rod 34 is rotatably connected to the top inner wall of the vertical slot 33 via a bearing, and the other end extends to the outside of the support plate 32 and is connected to a drive motor, which is also a servo motor. The sliding seat 35 is a rectangular block structure with threaded holes inside that are compatible with the threaded rod 34. The upper slide plate 37 and the lower slide plate 40 are both rectangular flat plate structures, and the guide rod 38 is cylindrical. The elastic springs 39 are made of carbon spring steel wire with a wire diameter of 0.8-1.8 mm and an outer diameter of 5-12 mm. Multiple elastic springs 39 are evenly distributed between the upper slide plate 37 and the lower slide plate 40. The outer diameter of the two positioning rollers 42 matches the inner diameter of the semi-circular groove I10, with a diameter of 10-20 mm, and the two positioning rollers 42 are located on both sides of the drill chuck 43. The lower slide plate 40 has a round hole with a diameter 2-5mm larger than the diameter of the drill bit clamped by the drill chuck 43, which is used to make way for the drill bit clamped by the drill chuck 43.

[0058] During the drilling positioning process, the drive motor on the support plate 32 is activated, which drives the threaded rod 34 to rotate. Since the sliding seat 35 is threadedly connected to the threaded rod 34, the rotation of the threaded rod 34 will cause the sliding seat 35 to move downward along the vertical slot 33. The sliding seat 35 will cause the upper slide plate 37 and the lower slide plate 40 to move downward as a whole. The two positioning rollers 42 at the bottom of the lower slide plate 40 extend into the two semi-circular grooves I10. Since the outer diameter of the positioning rollers 42 matches the inner diameter of the semi-circular grooves I10, the lower clamping plate 1 can be positioned when the positioning rollers 42 extend into the semi-circular grooves I10, so that the drill chuck 43 is located at the center line of the lower clamping plate 1. As the upper slide plate 37 and the lower slide plate 40 continue to move downward, the upper slide plate 37 compresses the elastic spring 39, and the elastic spring 39 undergoes elastic deformation. At the same time, the positioning rollers 42 clamp the lower clamping plate 1 under the action of the elastic spring 39, ensuring the stability of the lower clamping plate 1 during the drilling process. Furthermore, the upper slide plate 37 drives the drill chuck 43 to move downward. When the drill bit clamped by the drill chuck 43 contacts the lower clamping plate 1, drilling can be performed on the lower clamping plate 1.

[0059] Reference Figures 8-10 To protect components such as the lead screw 26, threaded rod 34, drill chuck 43, elastic spring 39, and guide rod 38, this equipment is also equipped with corresponding protective devices. Protective corrugated strips I 28 are fixed to both sides of the nut slider 27. The two protective corrugated strips I 28, with their opposite sides fixedly connected to the opposite inner walls of the slide groove 25, have a width matching the width of the slide groove 25. Made of rubber, they prevent debris and dust from entering the slide groove 25, thus protecting the lead screw 26. Corrugated tubes I 36 are fixed to the top and bottom inner walls of the vertical slot 33. The two corrugated tubes I 36, with their adjacent ends fixedly connected to the top and bottom of the sliding seat 35, respectively. The corrugated tubes I 36 are fitted onto the outer wall of the threaded rod 34. Also made of rubber, the corrugated tubes I 36 protect the threaded rod 34, preventing debris and dust from adhering to it and affecting its normal rotation. A bellows II 41 is fixed between the upper slide plate 37 and the lower slide plate 40, and the drill chuck 43, elastic spring 39 and guide rod 38 are all located inside the bellows II 41. The bellows II 41 is made of rubber, which can protect the drill chuck 43, elastic spring 39 and guide rod 38, and prevent debris and dust from entering between the upper slide plate 37 and the lower slide plate 40 and affecting the normal operation of the equipment.

[0060] In another embodiment: Refer to Figure 11In addition, to facilitate the collection and processing of debris generated during drilling, an auger 44 is rotatably connected inside the discharge chute 31. The auger 44 is cylindrical, with spiral blades on its outer wall, and the pitch is determined according to the debris discharge requirements. One end of the auger 44 is connected to a drive motor, which drives the auger 44 to rotate. During drilling by the drill chuck 43, the generated debris falls into the discharge chute 31. Then, the drive motor is started, and the drive motor drives the auger 44 to rotate. The spiral blades on the auger 44 discharge the debris in the discharge chute 31 to one side for easy collection later. A baffle plate 45 is slidably connected to the top of the movable worktable 24. The baffle plate 45 is a rectangular flat plate structure, and its size is determined according to the size of the movable worktable 24. A protective corrugated strip II 47 is fixed to the side of the baffle plate 45 away from the T-shaped guide block 29. The end of the protective corrugated strip II 47 away from the baffle plate 45 is fixed to the top of the movable worktable 24. The protective corrugated strip II 47 is made of rubber and can seal the gap between the baffle plate 45 and the movable worktable 24 to prevent debris leakage. A magnetic strip 46 is fixedly embedded on the side of the baffle plate 45 away from the protective corrugated strip II 47. The attraction force of the magnetic strip 46 is determined according to the weight of the baffle plate 45 and the positioning requirements, and is used to magnetically attract the baffle plate 45 to one side of the workpiece. When the lower clamping plate 1 or the upper clamping plate 2 is placed on the movable worktable 24 for positioning and drilling, the baffle plate 45 is attracted to one side of the lower clamping plate 1 and the upper clamping plate 2 by the magnetic attraction of the magnetic strip 46. Therefore, when the auger 44 rotates to discharge debris later, it can prevent the auger 44 from being exposed to the outside world and causing injury to the workers. In addition, the movement of the baffle plate 45 can also scrape off the debris on the movable worktable 24 and keep the movable worktable 24 clean.

[0061] The method for using positioning drilling equipment includes the following steps:

[0062] S1. When drilling is required on the lower clamping plate 1, the lower clamping plate 1 is placed on the movable worktable 24 with the two semi-circular grooves II8 facing upwards. The T-shaped electromagnet 30 is energized, and the lower clamping plate 1 is attracted to one side of the T-shaped guide block 29. The motor drives the lead screw 26 to rotate. The lead screw 26 and the nut slider 27 are threaded together, which drives the movable worktable 24 to move linearly, moving the lower clamping plate 1 to the bottom of the drill chuck 43 for drilling.

[0063] S2. The threaded rod 34 is driven to rotate by the motor. The threaded rod 34 is threadedly connected to the sliding seat 35. The sliding seat 35 drives the upper slide plate 37 and the lower slide plate 40 to move down as a whole. The two positioning rollers 42 at the bottom of the lower slide plate 40 extend into the two semi-circular grooves I10. Since the outer diameter of the positioning rollers 42 matches the inner diameter of the semi-circular grooves I10, the lower clamping plate 1 can be positioned when the positioning rollers 42 extend into the semi-circular grooves I10, so that the drill chuck 43 is located at the center line of the lower clamping plate 1. As the upper slide plate 37 and the lower slide plate 40 move down, the upper slide plate 37 compresses the elastic spring 39. The positioning rollers 42 clamp the lower clamping plate 1 under the action of the elastic spring 39, and the upper slide plate 37 drives the drill chuck 43 to move down, so that the lower clamping plate 1 can be drilled.

[0064] S3. When drilling is required on the upper clamping plate 2, place the upper clamping plate 2 on the movable worktable 24 with the two semi-circular grooves I10 facing down. When the T-shaped electromagnet 30 is energized, the upper clamping plate 2 is attracted to one side of the T-shaped guide block 29. The motor drives the lead screw 26 to rotate. The lead screw 26 and the nut slider 27 are threaded together to drive the movable worktable 24 to move linearly and move the upper clamping plate 2 to the bottom of the drill chuck 43 for drilling.

[0065] S4. The threaded rod 34 is driven to rotate by the motor, and the two positioning rollers 42 respectively abut against the arc surfaces on both sides of the upper clamping plate 2, thereby positioning the upper clamping plate 2 so that the upper clamping plate 2 is in the center position, which facilitates the drilling chuck 43 to drill.

[0066] S5. During the drilling process of the drill chuck 43, the generated debris falls into the discharge trough 31. Then, the motor drives the auger 44 to rotate, and the auger 44 discharges the debris in the discharge trough 31 to one side for easy collection later. In addition, when the lower clamping plate 1 or the upper clamping plate 2 is placed on the movable worktable 24 for positioning and drilling, the baffle plate 45 is attracted to one side of the lower clamping plate 1 and the upper clamping plate 2 by the magnetic attraction of the magnetic strip 46. Therefore, when the auger 44 rotates to discharge debris later, it can prevent the auger 44 from being exposed to the outside and causing injury to the workers.
