Description

Technical Field

[0001] The present invention belongs to the technical field of cable processing, and specifically relates to a stranding device for processing an electronic expansion valve connecting cable. Background Art

[0002] The stranding of an electronic expansion valve connecting cable is a high-performance cable design used in an electronic expansion valve system to ensure stable signal transmission and control. This stranded cable usually consists of multiple pairs of wires. After fine processing, the wires are wound together through a stranding process to reduce interference and noise in signal transmission, improve the anti-interference ability and transmission efficiency of the cable. Each pair of wires undergoes strict insulation treatment to ensure safe use in harsh environments. The electronic expansion valve controls the temperature of an air conditioner or refrigeration system by adjusting the refrigerant flow rate, and the quality of the cable directly affects the stability and performance of the system. Through a reasonable structural design, the stranded cable enhances the stability and durability of signal transmission, enabling it to operate reliably for a long time in environments such as high temperature, humidity, or vibration.

[0003] During the stranding process of the cable, generally multiple strands of wires are stranded into one strand. It is generally composed of a stranding device. Conventional stranding devices mainly include a wire guiding device, a wire gathering device, and a stranding device. When in use, multiple wires are guided through the wire guiding device and enter the interior of the wire gathering device for wire gathering, and finally are stranded through the stranding device. When this stranding device strands multiple strands of cables, it is limited by the shape of the wire guiding device, so it can only guide a specified number of wires. When stranding wires with different numbers, different specifications of wire guiding devices need to be replaced. At the same time, it cannot effectively guide wires with different thicknesses, and the processing efficiency is low.

[0004] Moreover, after the guiding and wire gathering are completed, multiple wires will enter the interior of the stranding device. However, the size of the stranding holes in the stranding device is fixed, and it can only effectively limit and complete the stranding of wires with a specified number and a specified diameter. When facing wires with different specifications, effective stranding cannot be carried out, and improvement is urgently needed. Summary of the Invention

[0005] The purpose of the present invention is to provide a stranding device for processing an electronic expansion valve connecting cable to solve the problems raised in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solution: A pair twisting device for processing an electronic expansion valve connecting cable, comprising a power box and bases installed on both sides of the bottom end of the power box. A plurality of guiding components are movably installed on the front surface of the power box in a wavy shape. A gear set is built in the power box to synchronously rotate the plurality of guiding components. The number of the guiding components is not less than five. An adjusting component is installed on the back surface of the power box, and the upper and lower ends of the adjusting component are connected to the plurality of guiding components. A wire collecting component is fixedly installed at the right end of the power box, and a pair twisting component is fixedly installed at the right end of the wire collecting component; The adjusting component acts on the plurality of guiding components to realize synchronous adjustment of the plurality of guiding components. The rear end of the adjusting component is communicated with an external air pump. When external high-pressure air is input, the adjusting component completes the adjustment and outputs hydraulic oil to act on the pair twisting component to complete synchronous adjustment of the pair twisting component.

[0007] Before cable pair twisting, traction devices can be installed on both sides of the device respectively. The traction device on the left is used to traction multiple wires into the device, while the traction device on the right is used to traction the pair-twisted wires. After connecting the adjusting component and the external air pump, the preparation before pair twisting is completed.

[0008] As a further technical solution of the present invention, the guiding component includes a guiding roller. A middle fixed disk is fixedly sleeved in the middle of the guiding roller. Side fixed disks are fixedly installed at both the front and rear ends of the guiding roller. Movable limiting disks are provided between the middle fixed disk and the side fixed disks. The movable limiting disks are movably clamped with the guiding roller through clamping slots.

[0009] As a further technical solution of the present invention, annular grooves are formed in the middle of the movable limiting disks. Annular limiting members are movably sleeved on the outer sides of the annular grooves. The movable limiting disks rotate relative to the annular limiting members. Extension frames are installed at the tops of the annular limiting members.

[0010] As a further technical solution of the present invention, first fixed seats are installed at the tops of the extension frames. Connecting rods are movably connected to the ends of the first fixed seats away from the extension frames through rotating shafts. Second fixed seats are movably connected to the ends of the connecting rods away from the first fixed seats through rotating shafts. The guiding component further includes a guiding plate. Both sides of the bottom end of the guiding plate are connected to the tops of the two second fixed seats. The rear end of the guiding plate is connected to the adjusting component.

[0011] When twisting four wires into one, the four wires can be placed between the upper and lower guide assemblies respectively, and the four wires can be placed between the side fixed disk and the movable limit disk and between the movable limit disk and the middle fixed disk respectively to complete the limited traction of the wires, and drive multiple guide assemblies to rotate through the power box, so that multiple wires enter the interior of the wire gathering assembly after being pulled by multiple guide assemblies and enter the interior of the wire twisting assembly after completing the wire gathering, completing the twisting process.

[0012] As a further technical solution of the present invention, the adjustment assembly includes an adjusting tube, which is connected to the rear end of the power box through a locking piece, and the upper and lower ends of the inner cavity of the adjusting tube are movably adjusted with adjusting plates, and the relatively distant ends of the two adjusting plates are fixedly installed with adjusting rods, and the relatively distant ends of the two adjusting rods pass through one end of the adjusting tube and are fixedly connected with a linkage plate, and the front end of the linkage plate is connected to the guide plate.

[0013] As a further technical solution of the present invention, a No. 1 three-way valve is provided at the rear end of the regulating tube, the rear end of the No. 1 three-way valve is connected to the external air pump, and the upper and lower ends of the No. 1 three-way valve are connected to the regulating tube near the upper and lower ends.

[0014] As a further technical solution of the present invention, the outer side surfaces of the adjusting rods are movably sleeved with adjusting springs, the upper and lower ends of the adjusting springs are respectively connected to one end of the inner cavity of the adjusting tube and one end of the adjusting plate, a drain valve is fixedly connected to one side of the middle part of the adjusting tube, the drain valve is connected to the stranded wire assembly, and hydraulic oil is filled between the two adjusting plates.

[0015] When it is necessary to guide and twist the two conductors, the external air pump can be turned on to input high-pressure air into the interior of the No. 1 three-way valve, and enter the upper and lower ends of the adjusting tube through the No. 1 three-way valve. At this time, the adjusting spring can be stretched and drive the two adjusting plates to be relatively close. At this time, the adjusting rod and the linkage plate are relatively close, and at the same time, multiple guide plates are driven to move in the direction close to the guide roller. At this time, the two connecting rods are deflected in the direction away from the middle, and thrust is applied to the two extension frames. At this time, the two extension frames are relatively far away from each other, and the two movable limit plates are driven to be relatively far away until the two movable limit plates are in contact with the side fixed plates. At this time, the wire can only pass through the gap between the two movable limit plates and the middle fixed plate. At this time, the device is suitable for the twisting process of the two conductors to complete the adaptive adjustment.

[0016] By utilizing the cooperation between the adjustment component and the guiding component, the adaptive adjustment of the guiding component can be realized through the action of the adjustment component, so that the guiding component can switch between the guiding modes of four wires and two wires. The whole switching process does not require the replacement of the guiding component, which can meet the simultaneous processing of different specifications of cables, significantly improve the practicability of the device, and improve the processing efficiency.

[0017] As a further technical solution of the present invention, the wire gathering component includes a limiting guide rail, one side of the limiting guide rail is connected to the power box, the upper and lower ends of the inner cavity of the limiting guide rail are both movably clamped with wire pressing plates, a limiting spring is installed between the limiting guide rail and the wire pressing plates, and wire gathering holes are equidistantly arranged on the front surface of the wire pressing plates.

[0018] When it is necessary to twist and pair two relatively thick wires, the guiding component can be adjusted through the adjustment component, and the distance between the movable limiting disc and the middle fixed disc is kept greater than the diameter of the wire. After the adjustment is completed, the wire can be passed through the wire gathering holes between the upper and lower wire pressing plates. At this time, the relatively thick wire can act on the upper and lower wire pressing plates, and the limiting spring can be compressed, driving the upper and lower wire pressing plates to move relatively away, and the limiting and wire gathering operations are completed through the upper and lower wire pressing plates, and the guiding process of the relatively thick wire is completed.

[0019] Through the cooperation of the adjustment component, the guiding component and the wire gathering component, the device can be adaptively adjusted for wires of different thicknesses, ensuring that relatively thick wires can also be normally guided through the device. The twisting and pairing process of different specifications of cables can be quickly realized without replacing the guiding component, significantly reducing the time for replacing accessories of the traditional device, and further improving the processing efficiency.

[0020] As a further technical solution of the present invention, the wire twisting component includes a fixed frame, the fixed frame is connected to one side of the limiting guide rail, a power disc is movably installed in the middle of the fixed frame, the power disc rotates relative to the fixed frame, a servo motor is fixedly installed on one side of the fixed frame, a driving gear is fixedly installed at the output end of the servo motor, a driven tooth ring is fixedly installed on the front surface of the power disc, the driving gear is meshed with the driven tooth ring, and the wire twisting component further includes a second three-way valve and two pressure pipes.

[0021] As a further technical solution of the present invention, the two pressure pipes are symmetrically installed at the upper and lower ends of the fixing frame close to the wire gathering assembly. One end of the second three-way valve is communicated with the flow discharge valve, and the upper and lower ends of the second three-way valve are communicated with the two pressure pipes. Piston plates are movably sleeved inside the pressure pipes. One ends of the piston plates away from the second three-way valve are fixedly installed with piston rods. One ends of the piston rods away from the piston plates penetrate through one side of the pressure pipes and are fixedly installed with pressure ball heads. The outer sides of the piston rods are movably sleeved with pressure springs. The upper and lower ends of the pressure springs are respectively connected with one end of the piston plate and one end of the pressure pipe.

[0022] When multiple wires are gathered through the wire gathering assembly, at this time, multiple wires can pass through the power disk and are squeezed and contacted inside the power disk. At this time, the servo motor is started, driving the driving gear to rotate. At this time, the driven toothed ring rotates accordingly, and the power disk rotates relative to the fixing frame, driving the wires inside to be twisted until they are twisted into one wire and then pulled out through an external traction device. And when facing the twisting of fewer wires, due to the relative approach of the two adjusting plates, at this time, the hydraulic oil located inside the adjusting pipe can be discharged through the flow discharge valve, enter the inside of the second three-way valve, and be introduced into the upper and lower pressure pipes through the upper and lower ends of the second three-way valve. At this time, the piston plates are displaced in the direction away from the second three-way valve under the action of pressure, the pressure springs are compressed accordingly, and at the same time, the piston plates and the piston rods are displaced in the direction away from the second three-way valve until the pressure ball heads contact the outer sides of the wires, completing the wire limiting process.

[0023] By utilizing the cooperation between the adjustment assembly and the wire twisting assembly, that is, after the adjustment assembly realizes the adaptive adjustment of the guiding assembly, the adaptive adjustment of the wire twisting assembly can be automatically completed, enabling the device to complete the adaptive process of cable limiting when facing fewer wires or cables with a smaller overall diameter. The whole process is automatically completed, and the twisting process of various specifications of wires can be realized, improving the versatility of the device.

[0024] The beneficial effects of the present invention are as follows: (1) By utilizing the cooperation between the adjustment assembly and the guiding assembly, the present invention can realize the adaptive adjustment of the guiding assembly through the action of the adjustment assembly, enabling the guiding assembly to switch between the guiding mode of four wires and the guiding mode of two wires. The whole switching process does not require the replacement of the guiding assembly, can meet the simultaneous processing of different specifications of cables, significantly improves the practicability of the device, and improves the processing efficiency.

[0025] (2) By utilizing the cooperation between the adjustment component and the stranding component, that is, after the adjustment component realizes the adaptive adjustment of the guiding component, the adaptive adjustment of the stranding component can be automatically completed. When the device faces cables with fewer conductors or a smaller overall diameter, the adaptive process of cable limiting can be completed, and the whole process is automatically completed. The stranding process of various specifications of conductors can be realized, improving the versatility of the device.

[0026] (3) Through the cooperation between the adjustment component, the guiding component, and the wire gathering component, the device can perform adaptive adjustments for different thicknesses of conductors, ensuring that thicker conductors can also be normally guided through the device. The stranding process of different specifications of cables can be quickly realized without replacing the guiding component, significantly reducing the time for replacing accessories in traditional devices and further improving the processing efficiency.

Ring-shaped limiting members 306 are movably sleeved on the outer sides of the ring grooves 305. The movable limiting plates 304 rotate relative to the ring-shaped limiting members 306. Extension frames 307 are installed at the tops of the ring-shaped limiting members 306. First fixing seats 308 are installed at the tops of the extension frames 307. Link rods 3010 are movably connected to one ends of the first fixing seats 308 away from the extension frames 307 through rotating shafts. Link rods 3010 are movably connected to second fixing seats 309 away from the first fixing seats 308 through rotating shafts. The guiding assembly 3 further includes a guiding plate 3011. Both sides at the bottom end of the guiding plate 3011 are connected to the tops of the two second fixing seats 309. The rear end of the guiding plate 3011 is connected to an adjusting assembly 4.

[0033] When conducting stranding, when stranding four wires into one wire, the four wires can be respectively placed between the upper and lower guiding assemblies 3, and the four wires can be respectively placed between the side fixing plates 303 and the movable limiting plates 304 and between the movable limiting plates 304 and the middle fixing plate 302 to complete the limiting traction of the wires. The power box 1 is driven to rotate a plurality of guiding assemblies 3, so that the multiple wires enter the inside of the wire gathering assembly 5 after being pulled by the plurality of guiding assemblies 3 and complete wire gathering and then enter the inside of the stranding assembly 6 to complete the stranding process.

[0034] such as Figure 2 and Figure 3 as well as Figure 4As shown in the figure, the adjustment component 4 includes an adjustment pipe 401. The adjustment pipe 401 is connected to the rear end of the power box 1 through a locking member. At both the upper and lower ends of the inner cavity of the adjustment pipe 401, adjustment plates 402 are movably adjusted. At one end of each of the two adjustment plates 402 facing away from each other, an adjustment rod 403 is fixedly installed. At one end of each of the two adjustment rods 403 facing away from each other, they penetrate through one end of the adjustment pipe 401 and are fixedly connected to a linkage plate 405. The front end of the linkage plate 405 is connected to the guide plate 3011. At the rear end of the adjustment pipe 401, there is a first three-way valve 407. The rear end of the first three-way valve 407 is connected to an external air pump. The upper and lower ends of the first three-way valve 407 are connected to the positions of the adjustment pipe 401 near the upper and lower ends. The outer sides of the adjustment rods 403 are movably sleeved with adjustment springs 404. The upper and lower ends of the adjustment springs 404 are respectively connected to one end of the inner cavity of the adjustment pipe 401 and one end of the adjustment plate 402. On one side of the middle of the adjustment pipe 401, a drain valve 406 is fixedly communicated. The drain valve 406 is connected to the wire twisting assembly 6. Hydraulic oil is filled between the two adjustment plates 402.

[0035] Embodiment: When it is necessary to guide and twist two wires, the external air pump can be turned on to input high-pressure air into the interior of the first three-way valve 407 and enter the upper and lower ends of the adjustment pipe 401 through the first three-way valve 407. At this time, the adjustment springs 404 can be stretched, driving the two adjustment plates 402 to move closer to each other. At this time, the adjustment rods 403 and the linkage plate 405 move closer to each other accordingly, and at the same time drive a plurality of guide plates 3011 to displace in the direction close to the guide roller 301. At this time, the two connecting rods 3010 deflect away from the middle, and apply a thrust to the two extension frames 307. At this time, the two extension frames 307 move away from each other accordingly, driving the two movable limit disks 304 to move away from each other until the two movable limit disks 304 come into contact with the side fixed disk 303. At this time, the wire can only pass through the gap between the two movable limit disks 304 and the middle fixed disk 302. At this time, the device is suitable for the twisting process of two wires, completing the adaptive adjustment.

[0036] By utilizing the cooperation between the adjustment component 4 and the guide component 3, through the action of the adjustment component 4, the adaptive adjustment of the guide component 3 can be realized, enabling the guide component 3 to switch between the guiding mode of four wires and the guiding mode of two wires. The entire switching process does not require replacing the guide component 3, which can meet the simultaneous processing of different specifications of cables, significantly improving the practicality of the device and the processing efficiency.

[0037] Such as Figure 1 and Figure 2 as well as Figure 6As shown, the wire gathering assembly 5 includes a limiting guide rail 501. One side of the limiting guide rail 501 is connected to the power box 1. Pressing plates 502 are movably clamped at both the upper and lower ends of the inner cavity of the limiting guide rail 501. A limiting spring 503 is installed between the limiting guide rail 501 and the pressing plates 502. Wire gathering holes 504 are equidistantly formed on the front surface of the pressing plates 502.

[0038] When it is necessary to twist and pair two relatively thick wires, the guiding assembly 3 can be adjusted through the adjusting assembly 4, and the distance between the movable limiting disc 304 and the middle fixed disc 302 is kept greater than the diameter of the wire. After the adjustment is completed, the wire can be passed through the wire gathering holes 504 between the upper and lower pressing plates 502. At this time, the relatively thick wire can exert a force on the upper and lower pressing plates 502. At this time, the limiting spring 503 can be compressed, driving the upper and lower pressing plates 502 to move relatively away from each other, and the limiting and wire gathering operations are completed through the upper and lower pressing plates 502, completing the guiding process of the relatively thick wire.

[0039] Through the cooperative action among the adjusting assembly 4, the guiding assembly 3, and the wire gathering assembly 5, the device can be adaptively adjusted for wires of different thicknesses, ensuring that relatively thick wires can also be normally guided through the device. Without replacing the guiding assembly 3, the twisting and pairing process of cables of different specifications can be quickly achieved, significantly reducing the time for replacing accessories in traditional devices and further improving the processing efficiency.

[0040] Such as Figure 7 and Figure 8 as well as Figure 9 and Figure 10As shown in the figure, the stranded wire assembly 6 includes a fixing frame 601. The fixing frame 601 is connected to one side of the limit guide rail 501. A power disk 602 is movably installed in the middle of the fixing frame 601. The power disk 602 rotates relative to the fixing frame 601. A servo motor 603 is fixedly installed on one side of the fixing frame 601. A driving gear 604 is fixedly installed at the output end of the servo motor 603. A driven gear ring 605 is fixedly installed on the front surface of the power disk 602. The driving gear 604 is meshed and connected with the driven gear ring 605. The stranded wire assembly 6 further includes a second three-way valve 606 and two pressure pipes 607. The two pressure pipes 607 are symmetrically installed at the upper and lower ends of the fixing frame 601 close to the wire gathering assembly 5. One end of the second three-way valve 606 is communicated with the drain valve 406. The upper and lower ends of the second three-way valve 606 are communicated with the two pressure pipes 607. Piston plates 608 are movably sleeved inside the pressure pipes 607. One ends of the piston plates 608 far away from the second three-way valve 606 are fixedly installed with piston rods 609. One ends of the piston rods 609 far away from the piston plates 608 penetrate through one side of the pressure pipes 607 and are fixedly installed with pressure ball heads 6011. The outer sides of the piston rods 609 are movably sleeved with pressure springs 6010. The upper and lower ends of the pressure springs 6010 are respectively connected with one end of the piston plates 608 and one end of the pressure pipes 607.

[0041] Embodiment: When multiple wires are gathered through the wire gathering assembly 5, at this time, multiple wires can pass through the power disk 602 and are squeezed and contacted inside the power disk 602. At this time, the servo motor 603 is started accordingly, driving the driving gear 604 to rotate. At this time, the driven gear ring 605 rotates accordingly, and the power disk 602 rotates relative to the fixing frame 601, driving the internal wires to be stranded. After being stranded into a single wire, it is pulled out through an external traction device. And when facing the stranding of fewer wires, due to the relative approach of the two adjusting plates 402, at this time, the hydraulic oil located inside the adjusting pipe 401 can be exported through the drain valve 406, enter the inside of the second three-way valve 606, and be introduced into the upper and lower two pressure pipes 607 through the upper and lower ends of the second three-way valve 606. At this time, the piston plates 608 are displaced in the direction away from the second three-way valve 606 under the action of pressure, the pressure springs 6010 are compressed accordingly, and at the same time, the piston plates 608 and the piston rods 609 are displaced in the direction away from the second three-way valve 606 until the pressure ball heads 6011 contact the outer side surface of the wire, completing the limiting process of the wire.

[0042] By utilizing the cooperation between the adjustment component 4 and the twisted wire component 6, that is, after the adaptive adjustment of the guide component 3 is achieved through the adjustment component 4, the adaptive adjustment of the twisted wire component 6 can be automatically completed, so that when the device faces a small number of wires or a cable with a smaller overall diameter, the adaptive process of the cable limit can be completed. The whole process is completed automatically, and the twisting process of wires of various specifications can be realized, thereby improving the versatility of the device.

[0043] Working principle and usage process: Before twisting the cables, traction devices can be installed on both sides of the device, wherein the traction device on the left is used to pull multiple wires into the device, and the traction device on the right is used to pull the wires after twisting. After connecting the adjustment component 4 with the external air pump, the preparation before twisting is completed; When twisting a pair, if four wires are twisted into one, the four wires can be placed between the upper and lower guide components 3 respectively, and the four wires can be placed between the side fixed disk 303 and the movable limit disk 304 and between the movable limit disk 304 and the middle fixed disk 302 respectively, to complete the limited traction of the wires, and drive the multiple guide components 3 to rotate through the power box 1, so that the multiple wires enter the interior of the wire collection component 5 after being pulled by the multiple guide components 3 and enter the interior of the wire twisting component 6 after completing the wire collection, completing the twisting process; When it is necessary to guide and twist the two conductors, the external air pump can be turned on to input high-pressure air into the interior of the No. 1 three-way valve 407, and enter the upper and lower ends of the regulating tube 401 through the No. 1 three-way valve 407. At this time, the regulating spring 404 can be stretched and drive the two adjusting plates 402 to be relatively close to each other. At this time, the adjusting rod 403 and the linkage plate 405 are relatively close to each other, and at the same time, the multiple guide plates 3011 are driven to move in the direction close to the guide roller 301. At this time, the two connecting rods 3010 are deflected in the direction away from the middle, and thrust is applied to the two extension frames 307. At this time, the two extension frames 307 are relatively far away from each other, and the two movable limit plates 304 are driven to be relatively far away until the two movable limit plates 304 are in contact with the side fixed plates 303. At this time, the wire can only pass through the gap between the two movable limit plates 304 and the middle fixed plate 302. At this time, the device is suitable for the twisting process of the two conductors to complete the adaptive adjustment; When it is necessary to twist two thicker wires, the guide assembly 3 can be adjusted by adjusting the assembly 4, and the spacing between the movable limit plate 304 and the middle fixed plate 302 can be kept larger than the diameter of the wire. After the adjustment is completed, the wire can be passed through the wire collection hole 504 between the upper and lower wire pressing plates 502. At this time, the thicker wire can exert force on the upper and lower wire pressing plates 502. At this time, the limit spring 503 can be compressed and drive the upper and lower wire pressing plates 502 to move relatively away from each other, and the upper and lower wire pressing plates 502 complete the limit and wire collection operations, completing the guiding process of the thicker wire; After multiple wires are gathered by the wire gathering component 5, multiple wires can then pass through the power disk 602 and make extrusion contact inside the power disk 602. At this time, the servo motor 603 is started accordingly and drives the driving gear 604 to rotate. At this time, the driven gear ring 605 rotates accordingly, and the power disk 602 rotates relative to the fixed frame 601 and drives the wires inside to be twisted. After being twisted into a single wire, it is pulled out through an external traction device; And when facing the twisting of fewer wires, due to the relative approach of the two adjusting plates 402, the hydraulic oil located inside the adjusting pipe 401 can be discharged through the flow discharge valve 406 at this time, and enters the inside of the second three-way valve 606, and is introduced into the upper and lower two pressurizing pipes 607 through the upper and lower ends of the second three-way valve 606. At this time, the piston plate 608 is displaced in the direction away from the second three-way valve 606 under the action of pressure, and the pressurizing spring 6010 is compressed accordingly. At the same time, it drives the piston plate 608 and the piston rod 609 to be displaced in the direction away from the second three-way valve 606 until the pressurizing ball head 6011 contacts the outer side of the wire, completing the wire limiting process.
