Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment technology for wire and cable production, and in particular to a core stabilizer for a wire and cable diameter measuring instrument. Background Technology

[0002] In the production process of wires and cables, online diameter measurement is a key step in controlling the accuracy of product specifications. The measurement accuracy of the diameter gauge directly determines the product quality of the wires and cables. During the transportation process, the wire core is easily affected by factors such as vibration of the conveying equipment, fluctuation of traction speed, and ambient airflow, which can easily cause radial sway and axial jitter in the X and Z axes. At the same time, problems such as wire core skew and coaxiality deviation may also occur.

[0003] In existing technologies, some diameter gauges only have a simple guide wheel structure at the front, which can only roughly limit the movement of the wire core in one direction. It cannot simultaneously eliminate the wobbling in the X-axis direction and the jitter in the Z-axis direction. The angle and coaxiality of the wire core when entering the diameter gauge are difficult to guarantee, which can easily lead to deviations in the diameter gauge's detection data and affect the product quality judgment. In addition, some stabilization devices have complex structures and poor adaptability. They cannot flexibly adjust the clamping force and limiting range according to wire cores of different diameters, and the disassembly and debugging are cumbersome, increasing production auxiliary time. At the same time, the contact between the traditional pulley structure and the wire core is hard friction, which can easily cause scratches on the surface of the wire core, affecting the appearance and insulation performance of the wire and cable. The pulley itself is also prone to wear, which can lead to a decrease in limiting accuracy and a short service life.

[0004] To address the aforementioned issues, there is an urgent need to design a core stabilizing frame that can achieve precise multi-directional positioning, strong adaptability, stable operation, and protection of the core, in order to eliminate positional deviations during core transportation, ensure the measurement accuracy of the diameter gauge, and improve the stability of wire and cable production. Summary of the Invention

[0005] The technical problem to be solved by this invention is that existing wire core stabilization devices have poor limiting effect, low adaptability, are prone to damaging the wire core, and are cumbersome to disassemble and debug.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: a wire core stabilizing frame for a wire and cable diameter measuring instrument, comprising a support column, a mounting base, two sets of spring-pressurized movable pulley assemblies, a fixed pulley assembly, a U-shaped guide wheel, a height adjustment mechanism, and a horizontal fine-tuning mechanism; the bottom end of the support column is provided with a fixed base, the height adjustment mechanism is located between the support column and the mounting base for adjusting the vertical height of the mounting base, and the horizontal fine-tuning mechanism is located on the mounting base for fine-tuning the horizontal position of the movable pulley assembly and the fixed pulley assembly; both the inlet and outlet ends of the mounting base are provided with U-shaped guide wheels for limiting the swaying amplitude of the wire core in the X-axis direction; the two sets of spring-pressurized movable pulley assemblies and the fixed pulley assembly are arranged sequentially along the wire core conveying direction and installed on the horizontal fine-tuning mechanism, the spring-pressurized movable pulley assembly is provided with a spring pressure mechanism for counteracting the jittering of the wire core in the Z-axis direction.

[0007] The height adjustment mechanism includes a lifting sleeve, a lifting screw, and a locking bolt. The lifting sleeve is fixedly sleeved on the top of the support column. The bottom end of the lifting screw is threadedly connected to the lifting sleeve, and the top end is fixedly connected to the bottom end of the mounting base. The locking bolt passes through the side wall of the lifting sleeve and abuts against the lifting screw.

[0008] The horizontal fine-tuning mechanism includes a horizontal slide rail, a sliding seat, and a positioning bolt. The horizontal slide rail is fixedly mounted on the mounting seat along the length of the mounting seat. The sliding seat is slidably connected to the horizontal slide rail. Both sets of the spring-loaded movable pulley assemblies and the fixed pulley assemblies are fixed on the sliding seat. The positioning bolt passes through the side wall of the sliding seat and abuts against the horizontal slide rail.

[0009] The U-shaped guide wheel has a U-shaped groove wall made of arc-shaped wear-resistant rubber layer. The U-shaped guide wheel is rotatably connected to the mounting base through a rotating shaft, and a rolling bearing is provided at the connection end between the rotating shaft and the U-shaped guide wheel. Several anti-slip grooves are formed on the surface of the arc-shaped wear-resistant rubber layer.

[0010] The spring-pressurized movable pulley assembly also includes a movable pulley bracket, a movable pulley, and a pulley height adjustment component. The spring pressing mechanism is mounted on the movable pulley bracket, and the pulley height adjustment component is located on the movable pulley bracket. A vertical sliding groove is provided on the side wall of the movable pulley bracket, and the rotating shaft of the movable pulley can slide up and down along the vertical sliding groove.

[0011] The spring compression mechanism includes a return spring, a pressure adjusting component, and a pressure sensor. The pressure sensor is located at the connection end between the return spring and the movable pulley bracket. The pressure adjusting component is an electrically controlled adjusting screw, which is adapted to the return spring and is used to adjust the compression of the return spring. Lateral compression springs with their bottoms in contact with the upper end of the movable pulley bracket are also provided on both sides of the inner top surface of the mounting base.

[0012] The fixed pulley assembly includes a fixed pulley bracket and a fixed pulley. Both the movable pulley and the fixed pulley have arc-shaped limiting grooves on their wheel surfaces, and the inner wall of the arc-shaped limiting grooves is covered with an antistatic and wear-resistant coating. The antistatic and wear-resistant coating is a polytetrafluoroethylene antistatic coating with a thickness of 0.3-0.5 mm.

[0013] The side wall of the support column is equipped with a control panel. The support column is a hollow column made of aluminum alloy with a wire channel inside. The pressure sensor is electrically connected to the control panel through the wire in the wire channel. The surface of the control panel is equipped with a pressure display screen and an adjustment knob.

[0014] The fixed base is a square metal base with several mounting holes on its surface. Expansion bolts are fitted into the mounting holes. The mounting base is a hollow frame structure with a dustproof cover in the hollow area.

[0015] The dust cover is made of transparent acrylic material, and has wire holes on both sides that are adapted to the wire core. The dust cover is detachably connected to the mounting base by a buckle.

[0016] The beneficial effects of this invention are: (1) The present invention achieves precise positioning of the wire core by setting U-shaped guide wheels with arc-shaped wear-resistant rubber layers at the inlet and outlet ends of the mounting base. Combined with the moving pulley assembly with spring pressure mechanism, the wire core vibration is counteracted. The double positioning structure effectively eliminates radial sway of the wire core, ensures the coaxiality and angle consistency of the wire core when it enters the diameter measuring instrument, avoids the diameter measurement error caused by the tilt of the wire core, and significantly improves the measurement accuracy. (2) The spring pressing mechanism of the present invention is equipped with a pressure sensor and a control panel, which can detect and display the pressure value applied to the wire core in real time. With the help of the pressure adjusting screw type pressure adjusting component, the compression amount of the reset spring can be accurately adjusted. At the same time, the moving pulley assembly is equipped with a pulley height adjusting component, which can adapt to the pressing and limiting requirements of wire cores of different diameters and specifications, and the adaptability of the device is greatly improved. (3) The present invention sets an arc-shaped wear-resistant rubber layer on the U-shaped guide wheel and attaches an anti-static wear-resistant coating in the limiting groove of the moving pulley and the fixed pulley. This not only reduces the hard friction between the wire core and the device and avoids scratching the surface of the wire core, but also prevents static electricity from affecting the insulation performance of the wire core. At the same time, it improves the wear resistance of the pulley and the guide wheel and extends the service life of the device. (4) The present invention is equipped with a height adjustment mechanism and a horizontal fine adjustment mechanism, which can adjust the vertical height of the mounting base and the horizontal position of the pulley assembly respectively, so as to achieve precise alignment between the device and the diameter measuring instrument, and facilitate disassembly and assembly and debugging, thereby reducing production auxiliary time; the bottom of the support column is equipped with a fixed base with expansion bolts to ensure the stability of the device during operation and avoid the impact of device vibration on the stability of the wire core. (5) The mounting base of the present invention is equipped with a transparent acrylic dust cover, which can effectively block dust and debris in the production environment from entering the device, prevent dust from adhering to the pulley and wire core surface and affecting the limit and measurement accuracy. The dust cover is detachable, which facilitates the cleaning and maintenance of the device. The support column adopts an aluminum alloy hollow structure, which reduces the overall weight of the device and can also build the wiring inside, ensuring that the device looks clean and the wiring is not easily damaged.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] like Figure 1-3 The diagram shows a wire core stabilizer for a wire and cable diameter gauge, comprising a support column 1, a mounting base 2, a spring-loaded movable pulley assembly 3, a fixed pulley assembly 4, a U-shaped guide wheel 5, a height adjustment mechanism 6, and a horizontal fine-tuning mechanism 7. A fixed base 8 is welded to the bottom of the support column 1. The height adjustment mechanism 6 is assembled between the support column 1 and the mounting base 2, used to flexibly adjust the vertical height of the mounting base 2 to accommodate diameter gauge inlets of different installation heights. The horizontal fine-tuning mechanism 7 is fixedly located within the hollow area of ​​the mounting base 2, used for fine-tuning the connection between the movable pulley assembly 3 and the fixed pulley assembly 4. The horizontal position of the pulley assembly 4 ensures precise alignment between the device and the diameter measuring instrument. U-shaped guide wheels 5, symmetrically mounted on the inlet and outlet ends of the mounting base 2, limit the swaying amplitude of the wire core in the X-axis direction, ensuring smooth horizontal transport of the wire core. Two sets of spring-pressurized moving pulley assemblies 3 and fixed pulley assemblies 4 are arranged sequentially along the wire core transport direction and fixed to the horizontal fine-tuning mechanism 7. The spring-pressurized moving pulley assembly 3 is equipped with a spring pressure mechanism 9, which applies stable pressure perpendicular to the Z-axis to the wire core, counteracting Z-axis jitter during wire core transport.

[0025] The height adjustment mechanism 6 includes a lifting sleeve 61, a lifting screw 62, and a locking bolt 63. The lifting sleeve 61 is fixedly sleeved on the top of the support column 1 by welding. The bottom end of the lifting screw 62 is threadedly connected to the internal thread of the inner wall of the lifting sleeve 61, and the top end of the lifting screw 62 is fixedly connected to the bottom end of the mounting base 2 by a flange. The locking bolt 63 is threaded through the side wall of the lifting sleeve 61 and abuts against the outer wall of the lifting screw 62. In actual adjustment, the lifting screw 62 is rotated, and the threaded engagement drives the mounting base 2 to move up and down vertically. After the height of the mounting base 2 is aligned with the inlet of the diameter gauge, the locking bolt 63 is tightened. The clamping force between the locking bolt 63 and the lifting screw 62 locks the position of the lifting screw 62, ensuring the stability of the height of the mounting base 2.

[0026] The horizontal fine-tuning mechanism 7 includes a horizontal slide rail 71, a sliding seat 72, and a positioning bolt 73. The horizontal slide rail 71 is fixed to the hollow area of ​​the mounting base 2 along its length by bolts. The sliding seat 72 is slidably connected to the horizontal slide rail 71. Both sets of spring-loaded movable pulley assemblies 3 and fixed pulley assemblies 4 are fixed to the top surface of the sliding seat 72. The positioning bolt 73 is threaded through the side wall of the sliding seat 72 and abuts against the outer wall of the horizontal slide rail 71. When adjusting the horizontal position, the sliding seat 72 is pushed to slide left and right along the horizontal slide rail 71, causing the pulley assemblies to move synchronously. After the center line of the pulley assembly coincides with the center line of the diameter gauge's inlet, the positioning bolt 73 is tightened to lock the horizontal position of the sliding seat 72, ensuring the coaxiality of the wire core conveying.

[0027] The U-shaped guide wheel 5 has an arc-shaped wear-resistant rubber layer bonded to its U-shaped groove wall. This arc-shaped wear-resistant rubber layer is made of nitrile rubber, and its surface has several uniformly distributed annular anti-slip grooves. The depth of the anti-slip grooves is 0.5-1mm, and the width is 1-1.5mm. The U-shaped guide wheel 5 is connected to the mounting base 2 via a lateral bracket. A rolling bearing is embedded at the connection end between the lateral bracket and the U-shaped guide wheel 5. The rolling bearing is a sealed deep groove ball bearing, effectively reducing the rotational resistance of the U-shaped guide wheel 5 and ensuring that the U-shaped guide wheel 5 rotates synchronously with the wire core during core feeding. The arc-shaped wear-resistant rubber layer not only avoids hard friction between the wire core and the U-shaped guide wheel 5, preventing scratches on the wire core surface, but also increases the contact friction with the wire core. Combined with the anti-slip grooves, this further restricts the swaying of the wire core in the X-axis direction, improving the stability of the wire core feeding.

[0028] The spring-loaded movable pulley assembly 3 further includes a movable pulley bracket 31, a movable pulley 32, and a pulley height adjustment component 33. The movable pulley bracket 31 is an inverted U-shaped metal bracket, fixed to the top surface of the sliding seat 72 by bolts. The spring pressure mechanism 9 is assembled on the inner side of the top of the movable pulley bracket 31. The pulley height adjustment component 33 is an adjustment bolt, threaded through the top of the movable pulley bracket 31. Vertical grooves 34 are provided on both side walls of the movable pulley bracket 31. The rotating shaft end of the movable pulley 32 passes through the vertical groove 34 and is threadedly connected to the bottom end of the pulley height adjustment component 33. The rotating shaft end of the movable pulley 32 can slide up and down along the vertical groove 34. Rotating the pulley height adjustment component 33 can drive the movable pulley 32 to move up and down along the vertical groove 34, realizing the adjustment of the vertical height of the movable pulley 32, adapting to the limiting requirements of wire cores of different diameters, and ensuring a tight fit between the movable pulley 32 and the wire core.

[0029] The spring pressure mechanism 9 includes a return spring 91, a pressure adjusting component 92, and a pressure sensor 93. The top end of the return spring 91 is fixedly connected to the inner side of the top end of the movable pulley bracket 31, and the bottom end is fixedly connected to the top end of the rotating shaft of the movable pulley 32. The pressure sensor 93 is located at the connection end between the return spring 91 and the movable pulley bracket 31. The pressure sensor 93 is a miniature pressure sensor. The pressure adjusting component 92 is an electrically controlled adjusting screw. The electrically controlled adjusting screw is driven by a motor at the top to rotate the hollow screw sleeved on its bottom drive shaft, thereby controlling the lifting and lowering of the hollow screw, and thus adjusting the compression of the return spring 91 axially fixed to the outside of the central control screw. Meanwhile, lateral compression springs are also installed on both sides of the inner top surface of the mounting base 2 through spring fixing seats. The bottom end of the lateral compression spring contacts the outer side of the upper end of the movable pulley bracket 31, applying horizontal compression force to the movable pulley bracket 31 to prevent the movable pulley bracket 31 from shifting horizontally during operation, further improving the stability of the movable pulley assembly 3 and ensuring the pressure limiting effect on the Z-axis direction of the core wire.

[0030] In actual use, rotating the pressure adjusting component 92 changes the compression of the return spring 91 by squeezing it, thereby adjusting the pressure applied by the return spring 91 to the rotating shaft of the movable pulley 32. This pressure is transmitted to the wire core through the movable pulley 32, achieving precise adjustment of the pressure in the Z-axis direction of the wire core. The pressure sensor 93 can detect the pressure value of the return spring 91 in real time and transmit the pressure signal to the control panel, so that the staff can keep track of the pressure application in real time, adapt to the clamping requirements of wire cores of different diameters and materials, and avoid damage to the wire core due to excessive pressure or failure to counteract Z-axis vibration due to insufficient pressure.

[0031] The fixed pulley assembly 4 includes a fixed pulley bracket 41 and a fixed pulley 42. The fixed pulley bracket 41 is fixed to the side of the sliding seat 72 by bolts. The fixed pulley 42 is rotatably mounted on the fixed pulley bracket 41. Both the movable pulley 32 and the fixed pulley 42 have arc-shaped limiting grooves 43 on their surfaces. The arc of the arc-shaped limiting grooves 43 matches the outer circumference arc of the wire core, ensuring that the wire core is embedded in the limiting groove. The inner wall of the arc-shaped limiting grooves 43 is coated with an antistatic and wear-resistant coating by spraying. The antistatic and wear-resistant coating is a polytetrafluoroethylene (PTFE) antistatic coating with a thickness of 0.3-0.5 mm. The PTFE antistatic coating has both excellent wear resistance and antistatic properties, reducing the coefficient of friction between the wire core and the pulley, reducing wear on the wire core surface, and preventing static electricity generated during wire core transportation, thus avoiding static electricity affecting the insulation performance of the wire core and improving the service life of the movable pulley 32 and the fixed pulley 42.

[0032] The supporting column 1 is a hollow column made of aluminum alloy. The aluminum alloy material effectively reduces the overall weight of the device, facilitating its handling and installation. An internal wiring channel 11 is formed to accommodate various wiring, ensuring a neat appearance and preventing exposed wiring from external wear. A control panel 10 is bolted to the side wall of the supporting column 1. The connecting wire of the pressure sensor 93 passes through the wiring channel 11 and is electrically connected to the control panel 10. A pressure display screen 12 and an adjustment knob 13 are embedded on the surface of the control panel 10. The pressure display screen 12 displays the pressure value detected by the pressure sensor 93 in real time. The adjustment knob 13 is electrically linked to the pressure regulating component 92, allowing operators to remotely adjust the rotation of the pressure regulating component 92 via the adjustment knob 13, thus conveniently adjusting the pressure of the return spring 91 without manual operation, improving operational efficiency.

[0033] The fixed base 8 is a square metal base with four rectangularly evenly distributed mounting holes on its surface. Expansion bolts 81 are fitted into the mounting holes. During installation, the fixed base 8 is placed against the ground or production equipment frame next to the diameter gauge inlet. The expansion bolts 81 are inserted into the mounting holes and tightened. The expansion force of the expansion bolts 81 is used to firmly fix the support column 1, preventing the device from shifting due to vibration during operation and ensuring the working stability of the device.

[0034] The mounting base 2 is an aluminum alloy hollow frame structure, which reduces the weight of the mounting base 2 and facilitates the threading of the wire core and the maintenance of the device. A dustproof cover 21 is snapped into the hollow area. The dustproof cover 21 is made of transparent acrylic material. The transparent design allows the staff to observe the wire core conveying and the working status of the device in real time. There are wire holes 211 on both sides of the dustproof cover 21, which can be used to insert the wire core into the device. There are buckles on both sides of the dustproof cover 21. The inner wall of the mounting base 2 has a slot that matches the buckles. The dustproof cover 21 is detachably connected to the mounting base 2 through the cooperation of the buckles and the slots. The dust cover 21 can effectively block dust, plastic debris, and other foreign objects in the production environment from entering the device, preventing dust from adhering to the surface of pulleys, guide wheels, and wire cores, and avoiding the impact of dust on the rotation flexibility of pulleys and guide wheels and the limiting accuracy of wire cores. At the same time, the detachable design makes it convenient for staff to clean, maintain, and replace the pulleys, guide wheels, and other components inside the device.

[0035] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
