Description

Technical Field

[0001] The present invention relates to the technical field of wire-wound resistor processing, and in particular to an auxiliary winding tool for a wire-wound resistor. Background Art

[0002] A wirewound resistor is a resistor element manufactured through a precision wire winding process. Its core structure consists of high-purity resistance wire wound on an insulating frame. The resistor core is usually made of insulating materials such as ceramic or glass fiber to ensure the electrical insulation performance of the resistance wire after winding. The resistance wire is generally made of nickel-chromium alloy or other alloys. Such materials have good resistance characteristics and stability. The end connector is used to connect the resistance wire to ensure the reliability of the electrical connection. The impregnating paint can be used to protect the resistance wire as needed to prevent it from moisture or erosion by the external environment.

[0003] Wirewound resistors, with their high precision and excellent stability, are widely used in various electronic devices. The winding process is a critical step in the production of wirewound resistors. The quality of this winding directly impacts a series of important performance indicators, such as the resistor's resistance accuracy and temperature coefficient. Therefore, to improve the winding quality of the resistor wire and ensure the stability and reliability of the quality, specially designed auxiliary winding tooling is often used in actual production.

[0004] However, most current auxiliary winding fixtures for wirewound resistors lack effective wire compression, resulting in loosely distributed resistor wire during winding, affecting overall resistance accuracy. Furthermore, during installation of the resistor core, the positioning accuracy and mechanical stability are insufficient, leading to assembly deviations or loose fixation. Summary of the Invention

[0005] To this end, the present invention provides an auxiliary winding tool for a wound resistor to solve the existing problem that the tool does not have a good resistance wire pressing function and has insufficient support for its positioning accuracy and mechanical stability when installing the resistor core body.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0010] A positioning rod is fixedly installed inside the left side of the fixed base plate, and a transmission block is slidably installed on the outside of the positioning rod. Transmission components are provided on the left and right sides of the transmission block to drive the transmission block to move. A clamping component is provided on the outer side of the upper end of the transmission block.

[0011] Furthermore, a first damping spring is arranged at an equal angle inside the right end of the connecting rod, and a limiting block is fixedly installed on the outside of the first damping spring, and the limiting block extends from one end away from the first damping spring to the inside of the fixed component.

[0012] Furthermore, the fixing assembly includes a mounting plate, a clamping block, a fixing ear and an electric telescopic rod. The mounting plate is installed inside the left side of the protective cover, and a mounting rod that rotates inside the protective cover is provided on the outer side of the lower end of the mounting plate. A clamping block is installed on the left side of the upper end of the mounting plate through a bearing, and there is a gap for movement between the outer side and the inner side of the protrusion on the left side of the clamping block and the resistor core body and the connecting rod respectively.

[0013] Furthermore, a fixing ear is fixedly provided on the middle part of the right side of the mounting plate, and an electric telescopic rod is installed on the inner side of the fixing ear through a rotating shaft, and the lower end of the electric telescopic rod is rotatably installed in the protective cover.

[0014] Furthermore, the support assembly includes a support frame, a mounting bar, an electromagnet and a magnetic block. The support frame is slidably installed on the upper end of the partition, and a mounting bar is fixedly installed on the outer side of the upper end of the support frame. The mounting bar plays a role in installing the ball.

[0015] Furthermore, the lower end of the support frame extends into the partition, a magnetic block is fixedly installed on the outer side of the lower end of the support frame, and a first damping spring also located in the partition is installed on the other side of the lower end of the support frame, an electromagnet located outside the magnetic block is installed inside the partition, and a switch button electrically connected to the electromagnet is provided on the outer surface of the partition.

[0016] Furthermore, the transmission assembly includes a connecting plate, a tooth block and a gear. The two groups of connecting plates are fixedly installed on the left and right sides of the transmission block and are slidingly connected to the fixed base plate. Multiple groups of tooth blocks are fixed to the upper right end of the connecting plate.

[0017] Furthermore, the upper end of the gear block is meshedly connected with a gear located in the protective cover, and the gear is fixedly mounted on the outer side of the mounting rod.

[0018] Furthermore, the clamping assembly includes an adjustment plate, a first mounting frame, a second damping spring, a second mounting frame and a roller. The adjustment plate is rotatably mounted on the outer side of the upper end of the transmission block through a hinge shaft, and the upper end of the adjustment plate is rotatably mounted with the first mounting frame through a hinge shaft. A second damping spring is provided inside the first mounting frame, and the outer side of the upper end of the second damping spring is connected to the second mounting frame. A roller located directly below the resistor core body is rotatably mounted inside the upper end of the second mounting frame.

[0019] Furthermore, fixed side panels are fixedly installed on both sides of the first mounting frame, and a limit plate is fixedly installed on the outer side of the lower end of the fixed side panel, a limit stand is slidably installed on the outer side of the lower end of the limit plate, and the limit stand is fixedly installed on the outer side of the upper end of the fixed base plate.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] 1. A second damping spring is provided inside the first mounting frame, and the outer side of the upper end of the second damping spring is connected to the second mounting frame. A roller located directly below the resistor core body is rotatably installed inside the upper end of the second mounting frame. As the first mounting frame moves to the uppermost position, the roller can contact the lower end of the resistor core body, and the second damping spring can generate an upward force on the second mounting frame and the roller. When the resistor core body is wound, the roller can press the resistor wire to prevent the resistor wire from being loosely distributed during the winding process, thereby improving the overall winding effect.

[0022] 2. A mounting bar is fixedly installed on the outer side of the upper end of the support frame. The mounting bar plays a role in installing the balls, so that multiple groups of balls can contact the two sides of the lower end of the resistor core body respectively, so as to support the resistor core body. At the same time, the clamping block can contact the right end of the resistor core body under the drive of the mounting plate, so that the clamping block can apply a leftward force to the resistor core body, thereby improving the stability of the installation of the resistor core body and facilitating the better rotation of the resistor core body, solving the problem of insufficient support for the positioning accuracy and mechanical stability of the resistor core body, which easily leads to assembly deviation or loose fixation;

[0023] 3. The outer end of the fixed side panel is located directly below the switch button. When the first mounting frame moves to the top, the fixed side panel presses the switch button, causing the switch button to turn off the power supply assembly installed in the partition, eliminating the electromagnetic field around the electromagnet. At this time, the electromagnet and the magnetic block are magnetically disconnected, causing the first damping spring, which was originally in an elongated state, to contract and drive the support frame to move away from the resistor core body, thereby facilitating the movement of the mounting bar and the ball, releasing the connection between the ball and the resistor core body, and preventing the mounting bar and the ball from affecting the winding work of the resistor core body.

[0036] The present application will be further described below in detail through specific embodiments in conjunction with the accompanying drawings.

[0037] like Figures 1 to 9 As shown, an auxiliary winding tool for a wire-wound resistor in an embodiment of the present invention includes: an auxiliary winding tool for a wire-wound resistor, including a mounting frame 1, a drive motor 4, a partition 15 and a positioning rod 3, a fixed base plate 2 is fixedly mounted on the lower end of the mounting frame 1, and a protective cover 9 is fixedly connected to the right side of the upper end of the fixed base plate 2;

[0038] Among them, a driving motor 4 is installed on the left side of the mounting frame 1, and the output end of the driving motor 4 is connected to a transmission rod 5. A connecting rod 6 connected to the fixed component is fixedly installed on the outside of the transmission rod 5, and a resistor core body 12 is provided on the outside of the connecting rod 6, which is convenient for installing the driving motor 4 through the mounting frame 1, so that the driving motor 4 can drive the resistor core body 12 to rotate through the transmission rod 5 and the connecting rod 6 when working, thereby facilitating the winding work of the resistor core body 12.

[0039] Partitions 15 are provided on the outer sides of the front and rear ends of the fixed base plate 2, and a support assembly located below the resistor core body 12 is installed on the outer side of the upper end of the partition 15. Balls 18 are embedded in the upper end of the support assembly at equal intervals.

[0040] Among them, the support assembly includes a support frame 16, a mounting bar 17, an electromagnet 19 and a magnetic block 20. The support frame 16 is slidably installed on the upper end of the partition 15, and a mounting bar 17 is fixedly installed on the outer side of the upper end of the support frame 16. The mounting bar 17 plays an installation role for the ball 18, so that multiple groups of balls 18 can respectively contact the two sides of the lower end of the resistor core body 12, thereby supporting the resistor core body 12, thereby ensuring the smooth effect of the resistor core body 12 during installation and movement.

[0041] A fixing assembly is installed on the inner side of the protective cover 9, and the fixing assembly includes a mounting plate 10, a clamping block 11, a fixing ear 13 and an electric telescopic rod 14. The mounting plate 10 is installed on the left inner side of the protective cover 9, and a mounting rod 26 that rotates inside the protective cover 9 is provided on the outer side of the lower end of the mounting plate 10. A clamping block 11 is installed on the left side of the upper end of the mounting plate 10 through a bearing, and the outer and inner sides of the left protrusion of the clamping block 11 respectively have gaps for movement with the resistor core body 12 and the connecting rod 6 to avoid the resistor core body 12 and the connecting rod 6 from affecting and blocking them when the mounting plate 10 rotates and moves.

[0042] The mounting rod 26 serves to mount the mounting plate 10, facilitating the rotation of the clamping block 11, thereby facilitating the installation and removal of the resistor core body 12. Furthermore, the clamping block 11 contacts the right end of the resistor core body 12, facilitating the application of a leftward force to the resistor core body 12 through the clamping block 11, thereby improving the stability of the installation of the resistor core body 12 and facilitating better rotation of the resistor core body 12. This solves the problem of insufficient support for the positioning accuracy and mechanical stability of the resistor core body 12, which can easily lead to assembly deviation or loose fixation.

[0043] At the same time, a fixing ear 13 is fixedly provided on the middle part of the right side of the mounting plate 10, and an electric telescopic rod 14 is installed on the inner side of the fixing ear 13 through a rotating shaft. The lower end of the electric telescopic rod 14 is rotatably installed in the protective cover 9, which facilitates the rotation of the mounting plate 10 by the extension and contraction of the electric telescopic rod 14, so that the electric telescopic rod 14 can better drive the mounting plate 10 through the fixing ear 13.

[0044] A first damping spring 7 is provided at an equal angle inside the right end of the connecting rod 6, and a limit block 8 is fixedly installed on the outside of the first damping spring 7. The limit block 8 extends from one end of the first damping spring 7 to the inside of the fixed component.

[0045] When the mounting plate 10 contacts the right side of the resistor core body 12, the protrusion on the left side of the clamping block 11 extends to the outside of the connecting rod 6. At this time, the protrusion squeezes the limit block 8, generating a force for it to approach the connecting rod 6, compressing the first damping spring 7, and generating a force for the limit block 8 to approach the protrusion, so that the limit block 8 is tightly connected to the protrusion, making it convenient for the connecting rod 6 to drive the clamping block 11 to rotate synchronously when rotating, thereby facilitating better driving the resistor core body 12 to rotate.

[0046] A positioning rod 3 is fixedly installed inside the left side of the fixed base plate 2, and a transmission block 23 is slidably installed outside the positioning rod 3. Transmission components are provided on both sides of the transmission block 23 to drive the transmission block 23 to move.

[0047] Among them, the transmission assembly includes a connecting plate 24, a tooth block 25 and a gear 27. Two sets of connecting plates 24 are fixedly installed on the left and right sides of the transmission block 23 and are slidably connected to the fixed base plate 2. Multiple sets of tooth blocks 25 are fixed to the upper right end of the connecting plate 24.

[0048] The upper end of the tooth block 25 is meshedly connected to a gear 27 located within the protective cover 9, and the gear 27 is fixedly mounted on the outside of the mounting rod 26. When the resistor core body 12 is manually placed on the two sets of mounting bars 17 and contacts the ball bearings 18, the mounting plate 10 and the mounting rod 26 are driven by the electric telescopic rod 14 to rotate counterclockwise, thereby applying pressure to the right side of the resistor core body 12. At this time, the mounting rod 26 can drive the gear 27 to rotate synchronously, thereby meshing the gear 27 with the tooth block 25, and driving the connecting plate 24 and the transmission block 23 to move synchronously to the right outside the positioning rod 3 and inside the fixed base plate 2, thereby facilitating the subsequent upward movement of the pressing assembly.

[0049] A clamping assembly is provided on the outer side of the upper end of the transmission block 23, and the clamping assembly includes an adjustment plate 28, a first mounting frame 29, a second damping spring 30, a second mounting frame 31 and a roller 32. The adjustment plate 28 is rotatably mounted on the outer side of the upper end of the transmission block 23 through a hinge shaft, and the upper end of the adjustment plate 28 is rotatably mounted with the first mounting frame 29 through a hinge shaft.

[0050] When the transmission block 23 moves, the upper and lower ends of the adjustment plate 28 can rotate with the first installation frame 29 and the transmission block 23 through the hinge axis respectively. At this time, the inclination angle of the adjustment plate 28 changes, thereby facilitating the change of the height of the first installation frame 29.

[0051] Fixed side panels 35 are fixedly mounted on both sides of the first mounting frame 29. A limit plate 33 is fixedly mounted on the outer side of the lower end of the fixed side panel 35. A limit stand 34 is slidably mounted on the outer side of the lower end of the limit plate 33. The limit stand 34 is fixedly mounted on the outer side of the upper end of the fixed base plate 2. When the inclination angle of the adjustment plate 28 changes, it can drive the limit plate 33 to slide within the limit stand 34, so that the limit plate 33 and the limit stand 34 can limit the first mounting frame 29, thereby improving its movement stability.

[0052] At the same time, a second damping spring 30 is provided inside the first mounting frame 29, and the outer side of the upper end of the second damping spring 30 is connected to the second mounting frame 31, and a roller 32 located directly below the resistor core body 12 is rotatably installed inside the upper end of the second mounting frame 31. As the first mounting frame 29 moves to the top, the roller 32 can contact the lower end of the resistor core body 12, and the second damping spring 30 can generate an upward force on the second mounting frame 31 and the roller 32. When the resistor core body 12 is wound, the roller 32 can press the resistor wire to avoid the resistor wire being loosely distributed during the winding process, thereby facilitating the improvement of the overall winding effect.

[0053] The lower end of the support frame 16 extends into the partition 15, and a magnetic block 20 is fixedly installed on the outer side of the lower end of the support frame 16, and a first damping spring 7 also located in the partition 15 is installed on the other side of the lower end of the support frame 16. An electromagnet 19 located outside the magnetic block 20 is installed inside the partition 15, and a switch button 21 electrically connected to the electromagnet 19 is provided on the outer surface of the partition 15.

[0054] A power supply assembly connected to an electromagnet 19 is located within the partition 15. When in normal operation, the power supply assembly provides electrical energy to the electromagnet 19. Current passes through the coil of the electromagnet 19, generating a magnetic field within the electromagnet 19 according to the principle of electromagnetic induction, thereby facilitating a stable magnetic connection between the electromagnet 19 and the magnetic block 20. Furthermore, a pull-out plate 22 is located directly below the power supply assembly, located on the outside of the partition 15. This allows for easy installation and maintenance of the power supply assembly by removing the pull-out plate 22. Heat dissipation holes are also provided throughout the pull-out plate 22 to facilitate heat dissipation.

[0055] Among them, the outer end of the fixed side panel 35 is located directly below the switch button 21. When the first mounting frame 29 moves to the top, the fixed side panel 35 presses the switch button 21, so that the switch button 21 turns off the power supply component installed in the partition 15, and the electromagnetic field around the electromagnet 19 disappears. At this time, the electromagnet 19 and the magnetic block 20 are released from the magnetic connection, so that the first damping spring 7, which was originally in an elongated state, shrinks and drives the support frame 16 to move away from the resistor core body 12, thereby facilitating the movement of the mounting bar 17 and the ball 18, releasing the connection between the ball 18 and the resistor core body 12, and preventing the mounting bar 17 and the ball 18 from affecting the winding work of the resistor core body 12.

[0056] How it works

[0057] First, the mounting frame 1 is stably placed at the designated position of the winding equipment, and then the resistor core body 12 is sleeved onto the outer side of the right end of the connecting rod 6. At the same time, the lower ends of the front and rear sides of the resistor core body 12 are in contact with the ball bearings 18. The resistor core body 12 is pushed from right to left, so that the left end of the resistor core body 12 is in contact with the transmission rod 5. When the mounting plate 10 contacts the right side of the resistor core body 12, the protrusion on the left side of the clamping block 11 extends to the outside of the connecting rod 6. At this time, the protrusion squeezes the limit block 8, generating a force for it to move closer to the connecting rod 6, compressing the first damping spring 7, generating a force for the limit block 8 to move closer to the protrusion, thereby tightly connecting the limit block 8 and the protrusion, making it easier for the connecting rod 6 to drive the clamping block 11 to rotate synchronously when rotating, thereby better driving the resistor core body 12 to rotate.

[0058] The electric telescopic rod 14 is activated to extend. As the electric telescopic rod 14 extends, its ends rotate with the protective cover 9 and the fixing ears 13, respectively, and the tilt angle changes, thereby driving the mounting plate 10 and the mounting rod 26 to rotate counterclockwise until the clamping block 11 contacts the right end of the resistor body 12, thereby facilitating the clamping block 11 to apply a leftward force to the resistor body 12.

[0059] When the mounting rod 26 rotates, it can drive the gear 27 to rotate synchronously, so that the gear 27 is meshed with the tooth block 25, and drives the connecting plate 24 and the transmission block 23 to move synchronously to the right on the outside of the positioning rod 3 and the inside of the fixed base plate 2. When the transmission block 23 moves, the upper and lower ends of the adjustment plate 28 can respectively rotate with the first mounting frame 29 and the transmission block 23 through the hinge axis. At this time, the inclination angle of the adjustment plate 28 changes, which makes it convenient to drive the first mounting frame 29, the fixed side plate 35 and the limit plate 33 to move upward, and at the same time, the limit plate 33 and the limit stand 34 slide.

[0060] As the first mounting frame 29 moves to the top, the roller 32 can contact the lower end of the resistor core body 12, and the second damping spring 30 can generate an upward force on the second mounting frame 31 and the roller 32. When the resistor core body 12 is wound, the roller 32 can press the resistor wire to avoid the resistor wire being loosely distributed during the winding process, thereby improving the overall winding effect.

[0061] At the same time, when the first mounting frame 29 moves to the top, the fixed side panel 35 presses the switch button 21, causing the switch button 21 to turn off the power supply assembly installed in the partition 15, and causing the electromagnetic field around the electromagnet 19 to disappear. At this time, the electromagnet 19 and the magnetic block 20 are released from the magnetic connection, causing the first damping spring 7, which was originally in an elongated state, to shrink, and drive the support frame 16 to move away from the resistor core body 12, thereby facilitating the movement of the mounting bar 17 and the ball 18, releasing the connection between the ball 18 and the resistor core body 12, and preventing the mounting bar 17 and the ball 18 from affecting the winding work of the resistor core body 12.

[0062] Start the drive motor 4, so that the drive motor 4 drives the transmission rod 5 and the connecting rod 6 to rotate synchronously, and drives the clamping block 11 to rotate through the first damping spring 7 and the limit block 8, thereby facilitating the stable rotation of the resistor core body 12, and then the resistor core body 12 can be wound through the winding equipment.

[0063] After the winding is completed, the resistor core body 12 can be removed by following the above steps in reverse order.

[0064] The technical features of the above embodiments can be combined arbitrarily (as long as there is no contradiction in the combination of these technical features). In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.
