Description

Technical Field

[0001] This invention relates to the field of nameplate mounting drilling devices, specifically to a double drilling device for mounting nameplates and a method for adjusting the drilling spacing. Background Technology

[0002] Composite insulators are key components of modern power transmission and transformation systems. Their safe operation depends on clear, durable, and traceable identification. Corrosion-resistant metal nameplates are usually installed on the fittings at both ends of the insulator. The nameplates are fixed to the peripheral side of the fittings at the end of the insulator by double-hole riveting.

[0003] The traditional method for drilling holes on the periphery of insulator fittings involves manual drilling with an electric drill or marking the holes manually before drilling. The hole spacing (the size of the central angle between the two holes) varies depending on the size and specification of the insulator. This traditional method is inefficient and difficult to match the pace of mass production. Manual positioning can easily lead to out-of-tolerance hole spacing, making it impossible to accurately position the hole spacing, affecting the flatness and firmness of the installation, and resulting in poor quality consistency. Uneven force can easily produce burrs, deformation, and damage to the nameplate. In addition, it is labor-intensive, and when manually operating the electric drill for non-radial drilling, it is easy to deviate, posing a safety hazard. Summary of the Invention

[0008] Furthermore, the telescopic assembly includes a pneumatic cylinder or a hydraulic cylinder.

[0009] Furthermore, the mounting plate is provided with an arc-shaped guide groove and a slider coupled and slidably disposed in the arc-shaped guide groove. The slider is disposed at the bottom of the drilling mechanism, and the arc-shaped guide groove is coaxial with the workpiece to be drilled.

[0010] Furthermore, the slider has a T-shaped structure, with its top end coupled and sliding in an arc-shaped guide groove and its bottom end located on the bottom surface of the mounting plate, for bolting the drilling mechanism to fix the drilling mechanism on the mounting plate.

[0012] Furthermore, the bottom of the punching mechanism is threaded with an adjustment knob that passes through the slider.

[0013] Furthermore, the arc-shaped guide groove includes an inner arc-shaped guide groove and an outer arc-shaped guide groove that are coaxial. A slider is slidably provided in both the inner and outer arc-shaped guide grooves, and the bottom end of the drilling mechanism is connected to the sliders in multiple arc-shaped guide grooves.

[0014] Furthermore, the mounting plate is provided with an arc-shaped protractor scale line, and the protractor scale line and the arc-shaped guide path are concentric; the drilling mechanism slidably mounted on the mounting plate is provided with an angle pointer that matches the protractor scale line for reading.

[0015] Furthermore, a drilling mechanism is fixedly installed, and the reading of the angle scale line corresponding to the drilling end of the drilling mechanism is zero degrees.

[0016] Furthermore, the drilling mechanism described herein is equipped with a toggle handle.

[0017] Furthermore, one drilling mechanism is fixedly mounted on the mounting plate, and another drilling mechanism is slidably mounted on the mounting plate along the arc-shaped guide path; the mounting plate is provided with a central shaft coaxial with the arc-shaped guide groove, and a slip ring is rotatably sleeved on the central shaft, with the slip ring fixedly connected to the drilling mechanism.

[0019] Furthermore, the central shaft is disposed on the bottom plate; the clamping mechanism includes a radially movable clamp for clamping the workpiece to be drilled on a set axis; the lower end side wall of the central shaft is provided with a slag discharge port.

[0020] Furthermore, the inner diameter of the central shaft is greater than twice the distance between the central shaft axis and the drilled end; the slag discharge port is connected to a negative pressure suction device.

[0021] In another aspect, the present invention provides a method for adjusting the hole spacing of a nameplate, using a double-drilling device for mounting nameplates provided by the present invention, the adjustment method comprising: The workpiece to be drilled is clamped and fixed by the clamping mechanism, so that the height of the workpiece to be drilled is adapted to the drilling end of the drilling mechanism. The drilling mechanism slides along the arc-shaped guide path, so that the actual included angle between the drilling ends of the two drilling mechanisms on the workpiece to be drilled reaches a preset angle; including using a central shaft as a rotation axis, so that one drilling mechanism rotates around the central shaft by a sliding ring, thereby realizing that the drilling mechanism slides along the arc-shaped path on the mounting plate; When the actual included angle is consistent with the preset included angle, the fixed drilling mechanism is on the mounting plate; Use the telescopic attachment to move the electric drill and drill holes in the workpiece.

[0022] The method for adjusting the hole spacing of a nameplate according to the present invention further includes obtaining the actual included angle by reading the actual central angle through a measuring scale line matched with the angle pointer on the hole punching mechanism.

[0023] According to a method for adjusting the hole spacing of a nameplate provided by the present invention, the method of using a telescopic component to move an electric drill to drill holes in the workpiece includes, The electric drill is driven by a cylinder to move radially along the arc-shaped guide groove, so that the drill bit drills a hole in the workpiece.

[0024] The beneficial effects of this invention include: 1. The part to be drilled is clamped and fixed by the clamping mechanism. Two drilling mechanisms are mounted on the mounting plate and point towards the part to be drilled. At least one drilling mechanism is slidably mounted on the mounting plate along the arc-shaped guide path. The angle between the two drilling mechanisms on the part to be drilled is adjusted by sliding the drilling mechanism along the arc-shaped guide path. After sliding into place and fixing, the drilling spacing can be made consistent, which is convenient to adjust the drilling spacing. It is suitable for insulators of various sizes and specifications and has high versatility. The telescopic component can drive the electric drill to move back and forth to drill holes in the part to be drilled, which is convenient to use. 2. The drilling mechanism can be fixedly installed on the base plate or slidably installed on the mounting plate. The telescopic component is set on the base plate and the electric drill is installed through the mounting bracket set on its reciprocating moving end. The electric drill drills holes by radially moving the mounting bracket through the reciprocating moving end. It is convenient to use and solves the problems of uneven force, burrs, deformation and high manual labor intensity. 3. The mounting bracket has a clever structure. The electric drill can be placed through the mounting holes on the fixing block. The opening slot extends from the mounting hole to the end face of the fixing block, so that the two sides of the opening slot have a certain degree of flexibility to form a clamping part. The two clamping parts can be bolted together to reduce the diameter of the mounting hole and clamp the electric drill, which is convenient to use. 4. The slider connects to the drilling mechanism. The slider slides in the arc-shaped guide groove to guide the drilling mechanism, so that the drilling mechanism can slide accurately along the arc-shaped guide path, which is convenient to use. 5. The slider has a T-shaped structure, with the top end coupled in the arc-shaped guide groove and the bottom end located on the mounting plate. When the slider is bolted and fastened to the drilling mechanism, it can be clamped and fixed on the mounting plate in conjunction with the drilling mechanism, which is convenient for adjusting the tightness and easy to use. 6. By using the angle measuring scale line, the reading can be taken by pointing the angle pointer to the scale line of the angle measuring scale line when the drilling mechanism slides in an arc, which makes it easy to accurately adjust the drilling spacing; 7. One drilling mechanism is fixed and the other is slidable. The drilling spacing can be adjusted by moving only one drilling mechanism, which is convenient to use. After connecting the central shaft to the slip ring, it can serve as the rotation axis of the drilling mechanism, providing support force when the drilling mechanism slides along the arc-shaped guide groove. This facilitates quick and easy sliding of the drilling mechanism along the arc-shaped guide path and avoids uneven force applied to the drilling mechanism, which can cause the angular velocities of the proximal and distal ends of the drilling mechanism to be inconsistent and thus prevent jamming during sliding. 8. A clamping mechanism can be installed through the bottom plate. The central shaft is a hollow structure. With the clearance area on the mounting plate, the clamping mechanism can clamp the workpiece to be drilled and extend it above the mounting plate. 9. The central axis is set on the bottom plate, which facilitates the collection of drilling debris and discharges it through the slag discharge port; when using radial movement, the clamp can fix the workpiece to be drilled on the set axis and coaxial with the arc guide path, and automatically calibrate the position of the workpiece to be drilled. 10. The drilling spacing adjustment method provided by the present invention fully utilizes the structural characteristics of the dual drilling device provided by the present invention. After the workpiece to be drilled is clamped and fixed by the clamping mechanism, the drilling mechanism slides along the arc-shaped guide path to adjust the actual included angle between the drilling ends of the two drilling mechanisms. This method is suitable for insulators of different sizes and specifications. After the spacing is adjusted and fixed, the electric drill is moved radially by the telescopic component to drill holes, maintaining high efficiency, high quality and consistency in drilling. This method can reduce the intensity of manual labor and is convenient to use.

[0025] The present invention relates to a dual-drilling device, which clamps and fixes the workpiece to be drilled on a set axis through a clamping mechanism. Two drilling mechanisms point to the workpiece to be drilled, and at least one drilling mechanism is slidably mounted on a mounting plate along an arc-shaped guide path around the set axis. The distance (central angle) between the drilling ends of the two drilling mechanisms can be adjusted by sliding along the arc-shaped guide path, which can accurately position the drilling and is convenient to use.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0031] This invention relates to a double-drilling device for installing nameplates. Drilling can be performed after adjusting the hole spacing on the arc-shaped part 3 to be drilled. The part 3 is clamped and fixed by a clamping mechanism 2. Two drilling mechanisms 4 are mounted on a mounting plate 1 pointing towards the part 3. At least one drilling mechanism 4 is slidably mounted on the mounting plate 1 along an arc-shaped guide path. Sliding the drilling mechanism 4 along the arc-shaped guide path adjusts the included angle between the two drilling mechanisms 4 on the part 3. After sliding and fixing in place, the drilling spacing is consistent, facilitating adjustment of the drilling spacing. It is suitable for insulators of various sizes and specifications, exhibiting high versatility. The telescopic component 43 can drive the electric drill 44 to reciprocate and drill holes on the part to be drilled. It is convenient to use and solves the problem of inconvenient positioning during manual drilling.

[0032] Example 1 A double-drilling device for mounting nameplates, specifically, such as... Figure 1-6 As shown, the device includes a mounting plate 1, a clamping mechanism 2, and a drilling mechanism 4. The clamping mechanism 2 is used to clamp and fix the part 3 to be drilled (such as an insulator) with an arc-shaped side surface, and clamps and fixes the part 3 to be drilled on a set axis. Two drilling mechanisms 4 are mounted on the mounting plate 1, with the drilling end of the drilling mechanism 4 pointing towards the part 3 to be drilled. At least one drilling mechanism 4 is slidably mounted on the mounting plate 1 along an arc-shaped guide path, and is used to adjust the angle between the drilling mechanism 4 and the other drilling mechanism 4 on the part 3 to be drilled. This can be understood as swinging around the part 3 to be drilled. The arc-shaped guide path is coaxial with the part 3 to be drilled. The drilling mechanism 4 includes a telescopic component 43 and an electric drill 44 located at the reciprocating end of the telescopic component 43. The telescopic component 43 is used to drive the electric drill 44 to reciprocate in the direction of approaching and moving away from the part 3 to be drilled, thereby adjusting the horizontal position of the drilling end relative to the part 3 to be drilled, thereby drilling a hole on the circumferential side surface of the part 3 to be drilled.

[0033] In one implementation, such as Figure 3 and Figure 5As shown, the drilling mechanism 4 includes a base plate 41, a mounting bracket 42, an electric drill 44, and a telescopic assembly 43. The base plate is fixedly mounted on the mounting plate 41 or slidably mounted on the mounting plate 1 along an arc-shaped guide path. The telescopic assembly 43 is mounted on the mounting plate 41. The mounting bracket 42 is located at the reciprocating moving end of the telescopic assembly 43. The electric drill 44 is mounted on the mounting bracket 42 and points towards the part 3 to be drilled. The telescopic assembly 43 is used to drive the mounting bracket 42 to slide in the direction of approaching and moving away from the part 3 to be drilled, so that the electric drill 44 drills a hole in the part 3 to be drilled, ensuring radial drilling. The drilling mechanism 4 can be fixedly installed or slidably installed on the mounting plate 1 via the base plate 41. The mounting bracket 42 is radially slidably installed on the floor along the arc-shaped guide path to install the electric drill 44. The telescopic component 43 is installed on the base plate 41 and the electric drill 44 is installed via the mounting bracket 42 located at its reciprocating moving end. The electric drill 44 drills holes by radially moving the mounting bracket 42 at the reciprocating moving end. It is convenient to use and solves the problems of uneven force application, easy generation of burrs and deformation, and high manual labor intensity.

[0034] The drilling mechanism 4 includes a mounting bracket 42, such as Figure 4-6 As shown, the mounting bracket 42 includes a fixing block 421. The fixing block 421 has a mounting hole 422 and an opening groove 423 communicating with the mounting hole 422. The opening groove 423 extends from the mounting hole 422 out of the end face of the fixing block 421, positioning the fixing block 421 on both sides of the opening groove 423 to form two clamping parts 424. The two clamping parts 424 are used to clamp and fix the electric drill 44 in the mounting hole 422 when bolted. The mounting hole 422 is axially oriented towards the part 3 to be drilled. After the electric drill 44 is installed, the drill bit of the electric drill 44 points towards the part 3 to be drilled. The mounting bracket 42 has an ingenious structure. The electric drill 44 can be placed through the mounting hole 422 on the fixing block 421. The opening groove 423 extends from the mounting hole 422 to the end face of the fixing block 421, giving the two sides of the opening groove 423 a certain degree of flexibility to form the clamping parts 424. Bolting the two clamping parts 424 can reduce the diameter of the mounting hole 422 to clamp the electric drill 44, making it convenient to use.

[0035] In one implementation, such as Figure 3 As shown, the reciprocating moving end of the telescopic component 43 is fixedly connected to the mounting bracket 42, and the fixed end of the telescopic component 43 is fixed to the base plate 41. The telescopic component 43 includes a cylinder or a hydraulic cylinder, and the telescopic component 43 is preferably a rodless cylinder. The drive block of the rodless cylinder is fixedly connected to the mounting bracket 42, and the fixing rod of the rodless cylinder is fixed to the base plate 41. The rodless cylinder is connected to an air source through an air pipe. By adjusting the pressure of the air source, the mounting bracket 42 is driven to move, thereby driving the electric drill 44 on the mounting bracket 42 to move radially to drill holes.

[0036] In one implementation, such as Figure 2 and 4As shown, the mounting plate 1 is provided with an arc-shaped guide groove 11 and a slider 47. The arc-shaped direction of the arc-shaped guide groove 11 is the aforementioned arc-shaped guide path. The arc-shaped guide groove 11 is coaxial with the workpiece 3 to be drilled. The slider 47 is coupled and slidably disposed within the arc-shaped guide groove 11 and connected to the bottom of the drilling mechanism 4. The slider 47 is connected to the drilling mechanism 4, and the guide mechanism provides guidance for the sliding of the drilling mechanism 4 by sliding the slider 47 within the arc-shaped guide groove 11, so that the drilling mechanism 4 can slide accurately along the arc-shaped guide path, which is convenient to use.

[0037] The guiding mechanism includes an arc-shaped guide groove 11 and a slider 47, such as Figure 4-5 As shown, slider 47 has a T-shaped structure (inverted). The top end of slider 47 is coupled and slides in the arc-shaped guide groove 11, and the bottom end is located on the bottom surface of the mounting plate 1. It is used to bolt the drilling mechanism 4 and fix the drilling mechanism 4 on the mounting plate 1. Slider 47 can be fixedly connected to the bottom of the drilling mechanism 4. Slider 47 is bolted to the mounting plate 1 using a bolt (the screwing part of the bolt abuts against the bottom surface of the mounting plate 1). Slider 47 can also be vertically adjustable and connected to the bottom of the drilling mechanism 4. For example, if the bolt passes through slider 47 and is screwed to the bottom surface of the drilling mechanism 4, slider 47 is located in the arc-shaped guide groove 11. When the bolt is tightened, the drilling mechanism 4 can be connected to slider 47 and fixed on the mounting plate 1.

[0038] Based on the fact that slider 47 has a T-shaped structure, such as Figure 4-5 As shown, the cross-section of the arc-shaped guide groove 11 is a T-shaped structure, and the T-shaped slider 47 is coupled and slides within the arc-shaped guide groove 11; the bottom of the drilling mechanism 4 is threadedly connected to an adjustment knob that passes through the slider 47. Using the adjustment knob as a bolt is convenient for manual tightening or loosening and sliding movement of the mechanism, making it easy to use.

[0039] In one implementation, such as Figure 2 As shown, the arc-shaped guide groove 11 includes a coaxial inner arc-shaped guide groove and an outer arc-shaped guide groove. A slider 47 is slidably provided in both the inner and outer arc-shaped guide grooves along its own arc direction. The bottom end of the punching mechanism 4 is connected to the sliders 47 in multiple arc-shaped guide grooves 11. Preferably, two concentric arc-shaped guide grooves 11 with different radii are located at the proximal end and distal end of the punching mechanism 4, respectively, to provide guidance for the arc-shaped sliding of the punching mechanism 4.

[0040] In one implementation, such as Figure 1-2As shown, the mounting plate 1 has an arc-shaped protractor scale line 5, which includes multiple radial graduation lines arranged along the arc-shaped path. The protractor scale line 5 is concentric with the arc-shaped guide path (i.e., the center of the scale line is on a set axial direction). The drilling mechanism 4, which is slidably mounted on the mounting plate 1, has an angle pointer 45 that matches the protractor scale line 5 for reading. In one specific embodiment, the protractor scale line 5 is located outside the arc-shaped guide groove 11, and the angle pointer 45 is radially positioned to point towards the protractor scale line 5. When the drilling mechanism 4 slides in an arc shape, the reading can be obtained by pointing to the graduations on the protractor scale line 5 through the angle pointer 45, which facilitates precise adjustment of the drilling spacing.

[0041] Based on the arc-shaped protractor scale line 5 on the mounting plate 1, a drilling mechanism 4 is fixedly mounted on the mounting plate 1 and the reading of the drilling end of the drilling mechanism 4 corresponding to the protractor scale line 5 is zero degrees (the fixed drilling mechanism 4 may also be equipped with an angle pointer 45 pointing to zero degrees). Another drilling mechanism 4 is slidably mounted on the mounting plate 1 along the arc-shaped guide path. When it is necessary to adjust the drilling spacing, one drilling mechanism 4 is slid along the arc-shaped guide groove 11, and the actual central angle of the drilling ends of the two drilling mechanisms 4 on the workpiece 3 to be drilled is determined by reading the angle pointer 45.

[0042] In a preferred embodiment, such as Figure 1-3 As shown, a punching mechanism 4 (sliding on the mounting plate 1) is provided with a toggle handle 46. The toggle handle 46 is preferably located at the distal end of the punching mechanism 4, so as to facilitate the punching mechanism 4 to slide around the central axis 6 along the arc-shaped guide groove 11.

[0043] In some implementations, such as Figure 1 As shown, one punching mechanism 4 is fixed to the mounting plate 1 (which can be bolted to the mounting plate 1 via the base plate 41), and another punching mechanism 4 is slidably mounted on the mounting plate 1 along an arc-shaped guide path. The mounting plate 1 has a central shaft 6 coaxial with the arc-shaped guide groove 11, meaning the center of the arc-shaped guide groove 11 is on the axis of the central shaft 6. A slip ring 61 is rotatably fitted around the central shaft 6, and the slip ring 61 can be rotatably mounted outside the central shaft 6 via a bearing. The slip ring 61 is fixedly connected to the punching mechanism 4. When the punching mechanism 4 slides along the arc-shaped guide path, the slip ring 61 rotates around the central shaft 6, providing a supporting rotating shaft for the arc-shaped sliding of the punching mechanism 4. After the slip ring 61 is fitted onto the central shaft 6, it can serve as the rotating shaft of the punching mechanism 4, providing support for the punching mechanism 4 as it slides along the arc-shaped guide groove 11. This facilitates quick and easy sliding of the punching mechanism 4 along the arc-shaped guide path and avoids uneven force applied to the punching mechanism 4, which could cause the proximal and distal ends of the punching mechanism 4 to have different angular velocities, resulting in jamming during sliding.

[0044] In a preferred embodiment, a bearing can be sleeved on the outside of the central shaft 6, with the outer ring of the bearing serving as a slip ring 61 to reduce the frictional force between the slip ring 61 and the central shaft 6 during rotation. In a specific embodiment, the central shaft 6 is a hollow stepped shaft structure, with the bearing sleeved on the central shaft 6, and the bottom surface of the inner ring of the bearing resting on the shoulder (stepped surface) of the stepped shaft.

[0045] Based on the fact that the mounting plate 1 has a central shaft 6, such as Figure 1 and 5 As shown, the dual-drilling device of the present invention also includes a bottom plate 7 spaced below the mounting plate 1. The bottom plate 7 can be connected to the mounting plate 1 through multiple supports. The central shaft 6 has a hollow structure, and the clamping mechanism 2 is fixed on the bottom plate 7 and located inside the central shaft 6. The mounting plate 1 is provided with a clearance area 12 for the clamping mechanism 2 to clamp the workpiece 3 to be drilled, so that the clamping mechanism 2 can clamp the workpiece 3 to be drilled and extend it above the mounting plate 1, where it can be drilled by the drilling mechanism 4. The clamping mechanism 2 can be installed through the bottom plate 7. The central shaft 6 has a hollow structure, which, in conjunction with the clearance area 12 on the mounting plate 1, allows the clamping mechanism 2 to clamp the workpiece 3 to be drilled and extend it above the mounting plate 1.

[0046] Based on the fact that the central axis 6 is a hollow structure, such as Figure 1 and 5 As shown, the central shaft 6 is mounted on the bottom plate 7; the lower side wall of the central shaft 6 is provided with a slag discharge port 62; the clamping mechanism 2 includes a radially movable clamp for clamping the part to be drilled 3 on a set axis. The central shaft 6 is mounted on the bottom plate 7 to facilitate the collection of drilling slag and discharge it through the slag discharge port 62, preventing slag from scattering and affecting the rotation of the slip ring 61 relative to the central shaft 6; when using radial movement, the clamp can fix the part to be drilled 3 on the set axis and coaxial with the center of the arc-shaped guide path, automatically calibrating the position of the part to be drilled 3.

[0047] In a further embodiment, the inner diameter of the central shaft 6 is more than twice the distance between the central shaft 6 axis and the drilling end (drill bit) when drilling; the slag discharge port 62 is connected to a negative pressure suction device to improve the collection effect of slag, and the negative pressure suction device can be set on the bottom plate 7.

[0048] In a specific plan, such as Figure 1As shown, mounting plates 1 are spaced apart on the bottom plate 7. Mounting plates 1 have clearance areas 12. A hollow central shaft 6 is fixed to the bottom plate 7. A clamping mechanism 2 is located on the bottom plate 7 within the central shaft 6, used to clamp the workpiece 3 to be drilled on a set axis, ensuring the drilling portion is higher than the mounting plate 1. Mounting plates 1 have an arc-shaped protractor scale line 5 centered on the set axis. The drilling ends of the two drilling mechanisms 4 point towards the axis of the central shaft 6 (the workpiece 3 to be drilled). One drilling mechanism 4 is fixed to the mounting plate 1, its drill bit pointing to zero degrees marked as the protractor scale line 5. Mounting plates 1 have an arc-shaped guide groove 11 centered on the set axis. A slider 47 is slidably coupled to the arc-shaped guide groove 11. The slider 47 is connected to the bottom end of another drilling mechanism 4, and the bottom end of this drilling mechanism 4 is threadedly connected to an adjustment knob passing through the slider 47. This drilling machine... The mechanism 4 is equipped with an angle pointer 45 that matches the reading of the protractor scale line 5; the drilling mechanism 4 is connected to a slip ring 61 sleeved on the central shaft 6, the central shaft 6 serves as the rotation axis of the drilling mechanism 4, and the slip ring 61 rotates around the central shaft 6 when the drilling mechanism 4 slides along the arc-shaped guide groove 11; the distal end of the drilling mechanism 4 is equipped with a toggle handle 46; the drilling mechanism 4 includes a base plate 41, a cylinder, a mounting bracket 42 on the drive block of the cylinder, and an electric drill 44 on the mounting bracket 42; the mounting bracket 42 includes a fixing block 421 and a radial mounting hole 422 and an opening groove 423 on the fixing block 421, the opening groove 423 connects to the mounting hole 422 and extends out of the end face of the fixing block 421, so that the fixing block 421 is located on both sides of the opening groove 423 to form a clamping part, and the electric drill 44 is clamped by bolting the two clamping parts to reduce the inner diameter of the mounting hole 422.

[0049] Example 2 like Figure 7 As shown, in this embodiment, two drilling mechanisms 4 are slidably provided on the mounting plate 1.

When the part to be drilled 3 is clamped and fixed, it is located on the set axis, and the center of the arc-shaped guide path is on the set axis, so that the part to be drilled 3 is coaxial with the arc-shaped guide path. S2. Slide the drilling mechanism 4 along the arc-shaped guide path until the actual included angle between the drilling ends of the two drilling mechanisms 4 on the workpiece 3 to be drilled is consistent with the preset included angle; including using the central shaft 6 as the rotation axis, so that one drilling mechanism 4 rotates around the central shaft 6 through the slip ring 61, thereby realizing that the drilling mechanism 4 slides along the arc-shaped path on the mounting plate 1; the central shaft 6 provides radial support force to maintain the smoothness of sliding and prevent the slider 47 connected to the drilling mechanism 4 from getting stuck in the arc-shaped guide groove 11; When the actual included angle is consistent with the preset included angle, the fixed drilling mechanism 4 is fixed on the mounting plate 1, which can achieve the consistency of the spacing of batch drilling. S4. Use the telescopic component 43 to move the electric drill 44 to drill holes in the part 3 to be drilled, including using a screwdriver to pass through the slider 47 to bolt the drilling mechanism 4 to fix the drilling mechanism 4. The method for adjusting the hole spacing of a nameplate according to the present invention further includes, S5. The actual included angle is obtained by reading the actual central angle through the angle pointer 45 on the punching mechanism 4 and matching the angle measuring scale line 5. According to the method for adjusting the hole spacing of a nameplate provided by the present invention, in step S4, the method of using the telescopic component 43 to radially move the electric drill 44 to drill holes in the part 3 to be drilled includes, S41. Use a cylinder to push the drilling mechanism 4 to move radially along the arc-shaped guide path, so that the drill bit of the electric drill 44 drills a hole in the workpiece 3 to be drilled.
