Description

Technical Field

[0001] This utility model relates to the field of broken wire removal tools, specifically to a spiral broken wire remover. Background Technology

[0002] Broken wires frequently occur during industrial production and equipment maintenance, especially in large filters and other equipment. Bolts, lead screws, and other components break due to long-term use, uneven stress, or corrosion, leaving broken wires inside the equipment, which seriously affects the normal operation of the equipment and subsequent maintenance work.

[0003] Currently, existing technologies, such as the Chinese invention patent application number CN201810656569.1, disclose a broken wire removal device. This device can conveniently and quickly remove broken wires from workpieces while avoiding damage to the workpiece threads. However, this device has significant drawbacks: manually rotating to remove the broken wire is not only laborious and inefficient, but also makes it difficult to precisely control the removal force, easily leading to wire breakage or damage to the device's base. Furthermore, the device lacks a displacement adjustment mechanism, making it unable to quickly and accurately align the broken wire when its location is complex, greatly limiting its application scenarios.

[0004] Meanwhile, other traditional methods for removing broken wires, such as using manual tools (chisels, punches, etc.) to remove the broken wire through hammering or chiseling, are not only difficult to operate and require a high level of skill from the operator, but also prone to causing secondary damage to the equipment during the hammering process, affecting its service life. Some methods use chemical agents to dissolve the broken wire, but this method is time-consuming, and the chemicals may corrode other parts of the equipment, presenting significant limitations. As equipment structures become increasingly complex, the requirements for the precision, efficiency, and safety of broken wire removal are constantly increasing. Existing broken wire removal tools are no longer sufficient to meet practical needs. Therefore, developing a highly efficient, precise, and easy-to-operate spiral-type broken wire extractor is of significant practical importance. Utility Model Content

[0005] The purpose of this invention is to provide a spiral-type broken wire extractor to solve the problems mentioned in the background art, such as the manual rotation method for extracting broken wires being not only laborious and inefficient, but also difficult to precisely control the extraction force, which can easily lead to wire breakage or damage to the equipment base.

[0006] To achieve the above objectives, this utility model provides a spiral-type broken wire extractor, comprising two broken wire extraction components. Each component is screwed into the drilled end of a broken wire, and then pulled outwards to extract the broken wire. The broken wire extraction components are driven by a Y-axis linear slide for Y-axis displacement adjustment, used to align the extracted wire extraction components with the broken wire. The Y-axis linear slide is driven by an X-axis linear slide for X-axis displacement adjustment, enabling the broken wire extraction components to pull outwards. The X-axis linear slides are symmetrically installed at both ends of the housing of the Y-axis linear slide. One end of the X-axis linear slide is equipped with a clamping component to clamp and fix the housing of a large filter.

[0007] This setup features two broken wire removal components driven by X-axis and Y-axis linear slides, allowing for precise displacement adjustment in both dimensions. The linear slides drive the broken wire removal components to pull the broken wire outward, which is more labor-saving and provides stable force application compared to traditional manual operation, thus reducing the operator's workload.

[0008] Preferably, the broken wire removal assembly includes a housing, the inner wall of which is provided with an internal thread, a threaded rod is connected to the internal thread of the housing, a connector is installed at the bottom end of the threaded rod, and a spiral cutter head is detachably installed at the bottom of the connector head, the spiral cutter head being used to rotate and screw into the end of the broken wire.

[0009] Preferably, a rotating rod is mounted on the top of the threaded rod, and a handle is mounted on the top of the rotating rod.

[0010] These two features include an internal thread on the inner wall of the housing that connects to the threaded rod. Combined with the rotating rod and handle at the top, the operator can easily rotate the threaded rod by rotating the handle, thereby causing the helical head to rotate and screw into the broken wire end.

[0011] Preferably, a vibration motor is installed on the slide of the Y-axis linear slide, a vibration plate is installed at the output end of the vibration motor, and the outer shell of the broken wire removal assembly is welded and fixed to the vibration plate.

[0012] Preferably, a speed controller is connected between the vibratory motor and the external power supply. The speed controller is used to adjust the vibration frequency of the vibratory motor so as to select an appropriate vibration intensity to assist in removing the broken wires of different materials and specifications.

[0013] These two components, including the vibrating motor and its connected speed controller, allow for adjustment of the motor's vibration frequency based on the material and specifications of the broken wire. During wire removal, the vibrating motor, via a vibrating plate, drives the wire removal assembly to vibrate, assisting the spiral cutter head in loosening the broken wire and effectively reducing damage to the broken wire and the equipment base during the removal process.

[0014] Preferably, the outer wall of the threaded rod is provided with scale lines, and the value of the scale lines protruding from the outer shell can intuitively display the screwing depth of the threaded rod inside the outer shell.

[0015] The scale lines on the outer wall of the threaded rod visually display the depth to which the threaded rod is screwed into the housing. By observing the values ​​protruding from the housing, operators can monitor the depth to which the screw head has screwed into the broken thread in real time, thus better controlling the process of removing the broken thread.

[0016] Preferably, the clamping component includes a connecting plate with a threaded hole in the middle and a clamping screw threadedly connected thereto. A pressure plate is installed at one end of the clamping screw, and the clamping screw drives the pressure plate to clamp and fix the outer wall of the large filter housing by screwing.

[0017] Preferably, the pressure plate has an anti-slip rubber layer on the side facing the large filter housing. The surface of the anti-slip rubber layer has multiple evenly distributed strip grooves to increase the friction between the pressure plate and the housing and prevent the clamping components from sliding during use.

[0018] These two settings use a tightening screw to press and fix the outer wall of the large filter housing to the pressure plate. This ensures the stability and safety of the broken wire removal operation; it also avoids direct hard contact between the pressure plate and the housing, preventing scratches on the housing surface, further protecting the equipment and extending its service life.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] In this spiral-type broken wire extractor, the broken wire extraction component is equipped with a rotatable threaded rod and handle. Combined with the spiral head cutter, it can easily screw into the broken wire end. Compared to traditional manual tapping or welding methods, this operation is more labor-saving and efficient. Simultaneously, the X-axis and Y-axis linear slides allow for precise displacement adjustment of the broken wire extraction component in two dimensions, enabling quick and accurate alignment of the broken wire at different locations. This significantly improves the efficiency and success rate of broken wire extraction, overcoming the shortcomings of existing devices that struggle to align broken wires in complex locations.

[0021] The design of the vibratory motor and its speed controller allows for adjustment of the vibration frequency based on the material and specifications of the broken wire. Vibration-assisted wire removal effectively reduces damage to the broken wire and the equipment substrate during the removal process, preventing wire breakage or equipment damage due to improper force control. Furthermore, the clamping plate of the clamping component features an anti-slip rubber layer and grooved strips, ensuring stable fixation while preventing scratches on the surface of the large filter housing, further protecting the equipment substrate.

[0022] The detachable design of the spiral cutter head in the broken wire removal assembly allows for the replacement of appropriate cutters according to different specifications of broken wires, improving the device's versatility. The scale lines on the outer wall of the threaded rod facilitate intuitive control of the screw-in depth by the operator, enabling better control of the broken wire removal process and adapting to various working conditions. Compared to existing technologies, this spiral broken wire extractor significantly improves the accuracy, efficiency, and safety of broken wire removal, effectively meeting the higher requirements for broken wire removal in modern industrial equipment maintenance.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides a spiral-type broken wire extractor, such as... Figure 1 As shown, it includes two broken wire removal components 3. The broken wire removal component 3 is used to screw into the drilled hole of the broken wire end, and then pulls the broken wire out by pulling it outward. The broken wire removal component 3 is driven by the Y-axis linear slide 2 to adjust the Y-axis displacement, which is used to adjust the position of the broken wire removal component 3 to align with the broken wire. The Y-axis linear slide 2 is driven by the X-axis linear slide 1 to adjust the X-axis displacement, so as to pull the broken wire removal component 3 outward. The X-axis linear slide 1 is symmetrically installed at both ends of the housing of the Y-axis linear slide 2. One end of the X-axis linear slide 1 is equipped with a clamping component to clamp and fix the housing of the large filter.

[0030] Two broken wire removal components 3 are driven by X-axis linear slides 1 and Y-axis linear slides 2, allowing for precise displacement adjustment in two dimensions. This enables the broken wire removal components 3 to quickly and accurately align with broken wires in different positions, whether in complex spatial locations or with varying spacing, efficiently completing position adjustment and significantly improving the efficiency and success rate of broken wire removal. This effectively overcomes the shortcomings of existing devices that struggle to align broken wires in complex positions. Simultaneously, driving the broken wire removal components 3 outwards via linear slides is more labor-saving and provides stable force application compared to traditional manual operation, reducing the operator's workload.

[0031] In this embodiment, as Figure 3 As shown, the broken wire removal assembly 3 includes a housing 31, the inner wall of the housing 31 is provided with an internal thread, the internal thread of the housing 31 is connected to a threaded rod 32, the bottom end of the threaded rod 32 is installed with a connector 33, and a spiral head cutter 34 is detachably installed at the bottom of the connector 33. The spiral head cutter 34 is used to rotate and screw into the end of the broken wire.

[0032] Specifically, such as Figure 3 As shown, a rotating rod 35 is mounted on the top of the threaded rod 32, and a handle is mounted on the top of the rotating rod 35.

[0033] In the broken wire removal assembly 3, the internal thread on the inner wall of the outer shell 31 is threadedly connected to the threaded rod 32. Combined with the rotating rod 35 and handle at the top, the operator can easily rotate the threaded rod 32 by rotating the handle, thereby causing the spiral head cutter head 34 to rotate and screw into the broken wire end. This structural design is simple and convenient to operate. Compared to traditional methods of manually hammering or welding to remove broken wires, it is not only less strenuous but also allows for more precise control of the screwing force and depth, avoiding unnecessary damage to the broken wire and equipment. Furthermore, the spiral head cutter head 34 is detachably mounted on the connector 33, allowing for the replacement of appropriate cutter heads according to different specifications of broken wires, greatly improving the versatility of the device and enabling it to adapt to various broken wire removal needs under different working conditions.

[0034] Furthermore, such as Figure 2 , Figure 3 As shown, a vibration motor 4 is installed on the slide of the Y-axis linear slide 2, and a vibration plate is installed at the output end of the vibration motor 4. The outer shell 31 of the broken wire removal assembly 3 is welded and fixed to the vibration plate.

[0035] Furthermore, a speed controller is connected between the vibration motor 4 and the external power supply. The speed controller is used to adjust the vibration frequency of the vibration motor 4 so as to select the appropriate vibration intensity to assist in removing the broken wires for different materials and specifications.

[0036] The vibration motor 4 and its connected speed controller mounted on the Y-axis linear slide 2 can adjust the vibration frequency of the vibration motor 4 according to the different materials and specifications of the broken wire. When removing the broken wire, the vibration motor 4 drives the housing 31 of the broken wire removal assembly 3 to vibrate via a vibrating plate, assisting the spiral cutter head 34 in loosening the broken wire, effectively reducing damage to the broken wire and the equipment base during removal. Especially for broken wires that are difficult to remove due to corrosion, jamming, or other reasons, adjusting the appropriate vibration intensity can reduce the difficulty of removal, avoid wire breakage or equipment damage due to improper control of the removal force, and improve the success rate of broken wire removal and equipment protection.

[0037] Furthermore, such as Figure 2 As shown, the outer wall of the threaded rod 32 is provided with scale lines 5. The value of the scale lines 5 that are exposed in the outer shell 31 can be used to visually display the screwing depth of the threaded rod 32 in the outer shell 31.

[0038] The scale line 5 on the outer wall of the threaded rod 32 can visually display the screwing depth of the threaded rod 32 inside the housing 31. By observing the value of the scale line 5 protruding from the housing 31, the operator can monitor the depth of the screw head 34 into the broken wire in real time, thereby better controlling the broken wire removal process. This helps to avoid damage to the equipment due to excessive screwing or ineffective removal of the broken wire due to insufficient screwing, further improving the accuracy and reliability of broken wire removal.

[0039] Furthermore, such as Figure 2 As shown, the clamping component includes a connecting plate 11, a threaded hole in the middle of the connecting plate 11, and a clamping screw 12 is threadedly connected thereto. A pressure plate 13 is installed at one end of the clamping screw 12. The clamping screw 12 drives the pressure plate 13 to clamp and fix the outer wall of the large filter housing by screwing.

[0040] Furthermore, the surface of the pressure plate 13 facing the large filter housing is provided with an anti-slip rubber layer. The surface of the anti-slip rubber layer has multiple evenly distributed strip grooves to increase the friction between the pressure plate 13 and the housing and prevent the clamping components from sliding during use.

[0041] In the clamping component, the clamping screw 12 drives the pressure plate 13 to press and fix the outer wall of the large filter housing. The anti-slip rubber layer and strip groove on the side of the pressure plate 13 facing the housing increase the friction between the pressure plate 13 and the housing. During the clamping process, it can ensure a stable fixation, prevent the extractor from sliding during operation, and ensure the stability and safety of the broken wire removal operation; it can also avoid the pressure plate 13 directly contacting the housing and causing scratches on the housing surface, further protecting the equipment base and extending the service life of the equipment.

[0042] When using the spiral broken wire extractor of this utility model, first place the spiral broken wire extractor next to the large filter from which the broken wire needs to be removed, and use the clamping component at one end of the X-axis linear slide 1 to fix the housing of the large filter. In specific operation, tighten the clamping screw 12, which moves the pressure plate 13 towards the outer wall of the housing. The anti-slip rubber layer and strip groove on the pressure plate 13 fit tightly against the housing, increasing the friction and firmly clamping the housing to prevent the extractor from sliding during subsequent operations.

[0043] The X-axis linear slide 1 and the Y-axis linear slide 2 work together to adjust the displacement of the broken wire removal assembly 3. Based on the position of the broken wire on the filter housing, the X-axis linear slide 1 is controlled to move the broken wire removal assembly 3 in the X direction, and the Y-axis linear slide 2 is controlled to move it in the Y direction, thereby quickly and accurately aligning the broken wire removal assembly 3 with the drilled end of the broken wire.

[0044] The operator grasps the handle at the top of the rotating rod 35 in the broken wire removal assembly 3 and rotates it clockwise, causing the rotating rod 35 and the threaded rod 32 to rotate. Since the threaded rod 32 is threadedly connected to the inner wall of the housing 31, the threaded rod 32 moves downwards while rotating, causing the helical head cutter 34 at the bottom of the connector 33 to rotate and screw into the drilled hole at the end of the broken wire. During this process, the operator can observe the value of the scale line 5 on the outer wall of the threaded rod 32 protruding from the housing 31 to monitor the screwing depth of the helical head cutter 34 in real time, ensuring appropriate screwing force and depth to avoid damaging the broken wire and the equipment.

[0045] Based on the material and specifications of the broken wire, adjust the speed controller connecting the vibration motor 4 to the external power supply to set a suitable vibration frequency. Turn on the vibration motor 4, which drives the housing 31 of the broken wire removal assembly 3 to vibrate through the vibration plate. The vibration is transmitted to the spiral head cutter head 34, which helps to loosen the broken wire that is difficult to remove due to rust, jamming, or other reasons, thus reducing the difficulty of removing the broken wire.

[0046] After the spiral cutter head 34 is firmly screwed into the broken wire and the broken wire is loosened, the X-axis linear slide 1 drives the Y-axis linear slide 2 and the broken wire removal assembly 3 to pull outward along the X-axis, thus removing the broken wire from the equipment and completing the broken wire removal operation.

[0047] Finally, it should be noted that the electronic components in the X-axis linear slide 1, Y-axis linear slide 2, etc. of this embodiment are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires. The specific connection method should refer to the working order between each electrical component in the above working principle to complete the electrical connection. All of these are technologies known in the art.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
