Description

Technical Field

[0001] This utility model belongs to the technical field of drilling auxiliary devices, and specifically relates to a drilling auxiliary device for insulating components. Background Technology

[0002] In the field of electrical equipment and electronic component manufacturing, insulating components are one of the key parts, widely used for electrical insulation, short circuit prevention, and stabilizing the installation of electronic components. Because insulating components are typically made of materials such as ceramics, glass fiber, and epoxy resin, which are relatively brittle and prone to cracking or precision deviations during processing, high requirements are placed on their drilling processes.

[0003] Currently, when drilling holes in insulating components, manual fixing or ordinary clamps are commonly used for positioning. However, due to the diverse shapes of insulating components, especially for irregularly shaped workpieces such as ellipsoids and spheres, traditional fixing methods have the following problems:

[0004] 1. Unstable positioning: Manual fixing or traditional fixtures cannot ensure that the workpiece remains stable during drilling, especially when the drill bit is in contact with the workpiece, which can easily cause shaking, resulting in drilling offset or increased dimensional error.

[0005] 2. Uneven stress on the workpiece: Because the ends of the ellipsoidal workpiece are relatively curved, conventional clamping methods are difficult to apply force evenly, which may lead to uneven stress on the workpiece surface, thereby causing cracks or damage.

[0006] 3. Inconvenient operation: Some fixtures have problems such as complicated adjustment and low clamping efficiency when clamping workpieces, which increases the difficulty of operation and reduces production efficiency.

[0007] 4. Insufficient safety: If the workpiece is not securely fixed during the drilling process, it may slip due to the high-speed rotation of the drill bit, which will not only affect the drilling quality but may also pose a safety hazard. Utility Model Content

It can stably clamp elliptical spherical insulating parts and effectively prevent the workpiece from shaking during the drilling process, thereby improving drilling accuracy, reducing damage rate and improving overall processing efficiency.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] An auxiliary device for drilling insulating components includes a support mechanism; the support mechanism includes a base plate, a vertical plate is fixedly connected to the top of one end of the base plate, a second horizontal plate and a first horizontal plate are fixedly connected to the side of the vertical plate from top to bottom, and a positioning tube is fixedly connected to the upper end of the base plate.

[0011] An extrusion component is movably connected to the positioning tube;

[0012] The extrusion component includes a guide post located inside the positioning tube, a spring being provided at the bottom of the guide post, and a connecting seat being fixedly connected to the top of the guide post;

[0013] Positioning blocks are provided on the upper end face of the connecting seat and the lower end face of the second horizontal plate;

[0014] During drilling, the workpiece to be drilled is located between the two positioning blocks.

[0015] Furthermore, one end of the positioning block is provided with a groove, the cross-sectional shape of which is an isosceles trapezoid; and an insertion hole is provided through the bottom of the groove.

[0016] Furthermore, a second through hole is provided above one end of the second horizontal plate;

[0024] Furthermore, a positioning seat is fixedly connected to the upper end face of the base plate, and the bottom end of the spring is sleeved on the positioning seat.

[0025] Furthermore, the upper end face of the base plate is symmetrically provided with fixing holes.

[0026] Compared with the prior art, the beneficial effects of this utility model are:

[0027] This utility model provides an auxiliary device for drilling insulating parts, which can effectively solve the problems of unstable positioning, uneven force, complex operation and insufficient safety of ellipsoidal workpieces during drilling in the prior art, improve drilling accuracy and processing efficiency, and reduce workpiece damage rate.

[0028] This invention utilizes a support mechanism, combining a base plate, uprights, and horizontal plates to form a stable support frame. The base plate is made of stainless steel, while the uprights and horizontal plates are made of high-strength metal and are fixed together with screws to ensure the overall structural stability. The fixing holes on the base plate allow for screw installation, ensuring the device is securely fixed to the drilling table and preventing movement or shaking during drilling, thus improving overall processing stability.

[0029] This invention features a positioning tube on a support mechanism, within which a pressing component is movably connected, allowing the pressing component to move smoothly along the axial direction of a guide column. A spring at the bottom of the guide column provides stable rebound force. When the handle presses the pressure arm, the pressing component moves downward, increasing the distance between the positioning blocks and facilitating workpiece placement. Upon releasing the handle, the positioning blocks automatically return to their original positions under the spring's action, ensuring even clamping of the workpiece. This structure avoids workpiece breakage caused by uneven force distribution in traditional clamps and also improves operational convenience.

[0030] This invention features an isosceles trapezoidal groove on the positioning block, with an insertion hole at the bottom of the groove. This allows an elliptical spherical workpiece to fit more closely to the groove shape, ensuring stable clamping at both ends of the workpiece and preventing wobbling during drilling. The size of the insertion hole matches the drill bit, allowing it to smoothly enter the groove and complete the drilling, guaranteeing precise drilling position, improving drilling quality, and reducing the error rate.

[0031] This invention features a rotating lower clamping component on a vertical plate. The lower clamping component comprises a lever arm, a first positioning pin, and a pin groove, ensuring good stability during rotation. The lever arm connects to the first positioning pin via a pin hole and inserts into a second positioning pin on the connecting seat, enabling stable downward pressure. The rubber-coated handle enhances grip comfort and improves operational safety. Operators can quickly clamp the workpiece with a light press of the handle, simplifying the operation and improving processing efficiency.

[0032] This invention utilizes a threaded groove on the top of the connecting seat and a threaded post fixedly connected to the positioning block, ensuring the positioning block is stably fixed on the connecting seat and maintaining a stable clamping force on the workpiece, while also improving the durability of the device. The bottom end of the spring is fitted inside the positioning seat on the base plate, providing precise rebound force after being subjected to force, ensuring the positioning block maintains appropriate clamping pressure and preventing the workpiece from shifting or falling off due to insufficient clamping force, thus improving drilling accuracy.

[0033] This invention provides a drilling auxiliary device with stable structure, reliable clamping, and convenient operation. It can effectively improve the drilling accuracy of elliptical spherical insulating parts, reduce errors caused by unstable clamping, improve overall processing efficiency, reduce workpiece breakage rate, and enhance production safety.

[0046] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0047] Example 1:

[0048] See Figure 1-5An auxiliary device for drilling insulating components includes a support mechanism 1. The support mechanism 1 includes a base plate 11, which is made of 10mm thick stainless steel to ensure structural stability and corrosion resistance. A vertical plate 13 is fixedly connected to one end of the base plate 11. The vertical plate 13 is made of high-strength aluminum alloy and is fixed to the base plate 11 by welding to ensure sufficient strength and rigidity, thereby providing stable support during drilling. A second horizontal plate 15 and a first horizontal plate 14 are fixedly connected to the side of the vertical plate 13 from top to bottom. Both the second horizontal plate 15 and the first horizontal plate 14 are made of carbon steel and are fixedly connected to the vertical plate 13 by screws to ensure the overall strength of the support structure and improve vibration resistance. A positioning tube 12 is fixedly connected to the upper end face of the base plate 11. The positioning tube 12 is made of wear-resistant alloy steel and is precision machined to ensure its fitting accuracy with the extrusion part 2, thereby effectively limiting the shaking of the extrusion part 2 during drilling and improving processing accuracy.

[0049] An extrusion component 2 is movably connected to the positioning tube 12. The extrusion component 2 includes a guide post 21 located inside the positioning tube 12. The guide post 21 is made of high-strength stainless steel and is polished to reduce friction and improve guiding accuracy, thereby ensuring that the extrusion component 2 moves smoothly inside the positioning tube 12. A spring 22 is provided at the bottom of the guide post 21. The spring 22 is made of 65Mn spring steel and has good elasticity and fatigue strength. It can provide stable rebound force during use to ensure that the ellipsoidal spherical workpiece always maintains a stable clamping force between the positioning blocks 3. A connecting seat 23 is fixedly connected to the top of the guide post 21. The connecting seat 23 is made of aluminum alloy and is formed by precision milling to ensure a tight fit between it and the guide post 21, thereby improving the overall stability and service life.

[0050] Positioning blocks 3 are provided on the upper end face of the connecting seat 23 and the lower end face of the second horizontal plate 15. The positioning blocks 3 are made of high-hardness alloy steel and have an anti-slip coating on the surface to improve the clamping force on the ellipsoidal workpiece and prevent the workpiece from shifting or being damaged due to uneven force during drilling. When drilling, the workpiece to be drilled is located between the two positioning blocks 3. The workpiece is stably fixed by the rebound action of the spring 22 to prevent the workpiece from shaking during drilling and to improve processing accuracy and safety.

[0051] See Figure 4The positioning block 3 has a groove 31 at one end. The cross-sectional shape of the groove 31 is an isosceles trapezoid. The trapezoidal groove design can enhance the fit of the ellipsoidal workpiece and make the workpiece more evenly stressed when clamped, thereby reducing processing errors. An insertion hole 33 is provided through the bottom of the groove 31. The diameter of the insertion hole 33 matches the diameter of the drill bit of the drilling machine, ensuring that the drill bit can be smoothly inserted and perform high-precision drilling. The inner wall of the insertion hole 33 is smoothed to reduce the frictional resistance of the drill bit during drilling, thereby improving drilling efficiency and accuracy.

[0052] See Figure 2-4 A second through hole 151 is provided above one end of the second horizontal plate 15. The axis of the second through hole 151 is in the same straight line as the axis of the drill bit to ensure that the drill bit can enter the insertion hole 33 vertically, thereby improving the accuracy and consistency of drilling. A threaded groove 231 is provided on the top of the connecting seat 23. The threaded groove 231 is used to cooperate with the fixing structure of the positioning block 3, so that the positioning block 3 can be firmly fixed on the connecting seat 23 and provide stable support force. A threaded post 32 is fixedly connected to the other end of the positioning block 3. The threaded post 32 is made of high-strength stainless steel and is treated with rust prevention to enhance durability and wear resistance.

[0053] See Figure 1-5 A lower pressure member 4 is rotatably connected to the upright plate 13. The lower pressure member 4 includes a lever arm 41 rotatably connected to the outside of the upright plate 13. The lever arm 41 is made of carbon steel and undergoes a heat treatment process to increase its durability and strength. A first positioning post 131 is fixedly connected to the outer side of the upright plate 13. The first positioning post 131 is made of hard alloy steel and is fixed to the upright plate 13 with bolts to ensure stability and impact resistance. One end of the lever arm 41 has a pin hole 412 that is fitted onto the first positioning post 131. The size of the pin hole 412 is closely matched with that of the first positioning post 131 to reduce the fitting clearance and improve the stability of the rotatable connection. Both sides of the receiving seat 23 are fixedly connected with second positioning posts 232. The second positioning posts 232 are made of carbon steel and are galvanized to prevent rust and oxidation, ensuring long-term reliability. The side of the lever arm 41 is provided with a pin groove 411 through which the second positioning posts 232 are inserted, so that the lever arm 41 can rotate stably and drive the extruder 2 to press down when the handle 42 is pressed, so as to realize the function of quickly clamping the workpiece. One end of the two lever arms 41 is connected to a handle 42. The handle 42 adopts a rubber-coated structure to provide a good grip and increase the anti-slip effect, ensuring that the operator can operate more comfortably and safely.

[0054] See Figure 2-4A first through hole 141 is provided above one end of the first horizontal plate 14. The inner diameter of the first through hole 141 matches the outer dimensions of the positioning block 3 to ensure that the positioning block 3 can be smoothly inserted and firmly fixed on the top of the connecting seat 23, thereby improving the stability and processing accuracy of the overall structure.

[0055] See Figure 2-3 A positioning seat 112 is fixedly connected to the upper end face of the base plate 11. The positioning seat 112 is made of aluminum alloy and is fixed to the base plate 11 by threaded connection to provide stable support for the spring 22 and prevent the spring 22 from shifting position due to long-term use. The bottom end of the spring 22 is sleeved on the positioning seat 112 so that it can rebound stably along the axial direction of the guide post 21 after being subjected to force, thereby improving the clamping effect of the workpiece.

[0056] See Figure 2 A fixing hole 111 is symmetrically and through the upper end face of the base plate 11. The diameter of the fixing hole 111 is 10mm and it matches the material of the base plate 11 so that high-strength screws can be used for fastening during installation, ensuring that the support mechanism 1 can be firmly fixed on the drilling table, thereby improving the overall safety and processing stability of the device.

[0057] Example 2: Improvement of the stability of the support mechanism

[0058] In this embodiment, the support mechanism includes a base plate 11, a vertical plate 13, a first horizontal plate 14, and a second horizontal plate 15, all made of 304 stainless steel plate with a thickness of 10mm to improve its strength and corrosion resistance. The base plate 11 is 300mm long and 200mm wide to ensure sufficient support area. The upper end of the base plate 11 has symmetrical through holes 111 with a diameter of 10mm, which are fixed with M8 high-strength alloy steel screws to ensure that the device can be firmly installed on the drilling table and thus avoid displacement during drilling. The vertical plate 13 is fixed to one end of the base plate 11 by welding and the overall rigidity is enhanced by angle support bars to ensure stable support during drilling.

[0059] Comparative Cases:

[0060] Without this improved solution, traditional drilling devices are fixed only by ordinary metal clamps, lacking a stable support structure. This results in significant vibration during drilling, making the workpiece prone to slight displacement and affecting machining accuracy. In addition, the support frame is relatively thin and is prone to deformation during continuous use, reducing the device's lifespan. In contrast, the support mechanism in this embodiment provides a more stable support effect and effectively reduces drilling errors, improving machining accuracy.

[0061] Example 3: Improvement of the workpiece clamping mechanism

[0062] In this embodiment, the extrusion component 2 is movably connected inside the positioning tube 12. The extrusion component 2 includes a guide post 21, a spring 22, and a connecting seat 23. The guide post 21 is made of high-strength 40Cr alloy steel and is hardened to achieve a hardness of HRC50 or higher to ensure sufficient wear resistance and impact resistance. The diameter of the guide post 21 is set to 12mm, and the gap between it and the inner diameter of the positioning tube 12 is controlled within 0.05mm to ensure that the guide post 21 moves smoothly inside the positioning tube 12 without shaking. The spring 22 is made of 65Mn spring steel, with a spring diameter of 8mm and a rebound force of 15N to ensure that it can quickly return to its original position and firmly clamp the workpiece after the handle 42 is released. The connecting seat 23 is made of aluminum alloy and is precision machined by CNC to form a tight fit with the guide post 21, improving the stability and durability of the clamping mechanism.

[0063] Comparative Cases:

[0064] In traditional clamping methods, manual clamps are typically used to fix the workpiece. However, this method is prone to uneven clamping force during drilling, causing slight displacement of the workpiece and affecting drilling accuracy. In addition, due to the unstable manual clamping force, the spring is prone to losing elasticity after long-term use, resulting in a decrease in clamping effect. In contrast, this embodiment optimizes the cooperation design of the guide post 21 and the spring 22, enabling the workpiece to maintain a stable clamping state at all times, improving drilling accuracy and reducing the workpiece damage rate.

[0065] Example 4: Drilling Accuracy Improvement Scheme

[0066] In this embodiment, the structure of the positioning block 3 has been optimized. The positioning block 3 is made of high-hardness GCr15 bearing steel with a hardness of HRC58 or higher, and an anti-slip coating is added to the surface to improve the clamping force on the workpiece. One end of the positioning block 3 is provided with an isosceles trapezoidal groove 31. The width of the groove 31 is set to 20mm and the depth is set to 8mm, so as to better fit the elliptical spherical workpiece and make the workpiece be subjected to uniform force during clamping, thereby improving the stability of drilling. The bottom of the groove 31 is provided with an insertion hole 33. The diameter of the insertion hole 33 is set to 6mm, which is consistent with the diameter of the drill bit, and is precision machined by CNC to ensure that the drill bit can be smoothly inserted and ensure the accuracy of the drilling position.

[0067] Comparative Cases:

[0068] Without this optimized design, traditional clamping devices typically use V-groove or straight clamping methods. However, for elliptical or spherical workpieces, this can lead to uneven force distribution, causing the workpiece to rotate or wobble slightly during drilling, thus affecting the drilling accuracy. In contrast, this embodiment uses an isosceles trapezoidal groove structure, which can better fit the shape of the workpiece, ensure the accuracy of the drilling position, and improve processing precision.

[0069] Example 5: Operation Ease Optimization Scheme

[0070] In this embodiment, the structural design of the pressing component 4 has been optimized. The pressing component 4 includes a lever arm 41, a first positioning post 131, a pin hole 412, a pin groove 411, and a second positioning post 232. The lever arm 41 is made of Q235 carbon steel and is powder coated to improve its corrosion resistance and service life. The length of the lever arm 41 is set to 150mm to ensure that the operator can easily apply pressure and reduce operating resistance through leverage, making the workpiece clamping process smoother. The handle 42 adopts a rubber-coated structure with a diameter of 30mm to improve grip comfort and enhance anti-slip effect.

[0071] Comparative Cases:

[0072] In traditional devices, clamping workpieces usually requires bolting or manual adjustment of multiple clamps, which is not only complicated to operate, but also prone to workpiece wobbling due to uneven clamping force. In contrast, this embodiment optimizes the lever structure, allowing the operator to quickly clamp the workpiece by simply pressing the handle 42, which improves the convenience and efficiency of operation, while reducing the labor intensity of the operator.

[0073] Example 6: Clamping Force Stability Optimization Scheme

[0074] In this embodiment, a threaded groove 231 is opened on the top of the connecting seat 23, and a threaded post 32 is fixedly connected to the other end of the positioning block 3. The threaded post 32 is made of stainless steel and is treated with anti-rust to enhance durability and wear resistance. The diameter of the threaded groove 231 is set to 8mm and is in close fit with the diameter of the threaded post 32 to ensure that the clamping structure can be locked securely and reduce the possibility of loosening after long-term use. The bottom end of the spring 22 is sleeved on the positioning seat 112 on the base plate 11. The positioning seat 112 is made of aluminum alloy and is precision machined to ensure that the spring can be stably positioned so that the clamping force is always within a reasonable range, avoiding displacement or falling off of the workpiece due to insufficient clamping force.

[0075] Comparative Cases:

[0076] Before this design was optimized, the clamping force of traditional fixtures usually relied on manual adjustment, which could easily lead to insufficient or excessive clamping force due to improper operation, causing the workpiece to slip or be damaged during drilling. In contrast, this embodiment uses the precise fit of the threaded groove and threaded post to make the clamping force more stable and ensure that it can maintain a good clamping effect after long-term use, thereby improving the overall machining accuracy and the service life of the equipment.

[0077] The working principle of this utility model is as follows:

[0078] When in use, the support mechanism 1 is installed below the drilling machine. When installing the support mechanism 1, screws are installed in the fixing hole 111. The base plate 11 is connected to the drilling table by the screws, and the axis of the drill bit of the drilling machine is aligned with the axis of the second through hole 151. This allows the drill bit to move downwards and vertically extend into the insertion hole 33 to drill the elliptical spherical workpiece located between the two positioning blocks 3.

[0079] After the support mechanism 1 is installed, hold the handle 42 and press it down. This will cause the extruder 2 to move downward. As the extruder 2 moves downward, the distance between the two positioning blocks 3 will increase. Then, place the ellipsoidal workpiece to be drilled into the groove 31. Then, release the hand that is pressing the handle 42. Under the elastic force of the spring 22, the two positioning blocks 3 will move closer to each other. As the positioning blocks 3 move closer, the ellipsoidal workpiece will be fixed between the two positioning blocks 3.

[0080] During the drilling operation, the drill bit of the drilling machine will extend from the insertion hole 33 into the groove 31 and drill a hole in the ellipsoidal workpiece. Since the two ends of the ellipsoidal workpiece are fixed in the groove 31, the ellipsoidal workpiece can be prevented from shaking during the drilling operation.

[0081] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
