Description

Technical Field

[0001] This utility model belongs to the technical field of pneumatic thread twisting and straightening machines, specifically relating to a pneumatic thread twisting and straightening machine. Background Technology

[0002] In the production process of low-voltage wiring harnesses for new energy applications, twisting the twisted-pair wires (the part where the two colored wires are twisted together) is a crucial step. The purpose is to separate the twisted pairs into two individual, straight wires. This has numerous advantages: firstly, it ensures that each wire is in optimal condition, effectively reducing signal attenuation and distortion caused by twisting or irregular arrangement, greatly improving the stability and speed of data transmission; secondly, it facilitates subsequent wiring work, and a clear and orderly wiring layout significantly reduces the time and difficulty required for troubleshooting, greatly improving work efficiency.

[0003] Currently, existing wire twisting and straightening machines primarily rely on manual handling, where one end of the wire bundle is held by hand while the other end is inserted into the machine. However, this manual method of securing the wire bundle has significant drawbacks. During machine operation, the wire bundle can move due to the machine's movement, and if the operator is even slightly negligent, the bundle is highly likely to slip from their hand. If this happens, it will not only interrupt the normal twisting process but may also damage the already twisted portion of the wire bundle, severely impacting production progress. Utility Model Content

[0004] The purpose of this invention is to provide a pneumatic yarn twisting and straightening machine, aiming to solve the problem that existing yarn twisting and straightening machines rely mainly on manual handling of one end of the yarn bundle while inserting the other end into the machine. However, this manual method of securing the yarn bundle has significant drawbacks. During machine operation, the yarn bundle may move due to the machine's movement, and if the operator is slightly negligent, the yarn bundle is very likely to slip from their hand. If this happens, it will not only interrupt the normal yarn twisting process but may also damage the already twisted portion of the yarn bundle, seriously affecting production progress.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic yarn twisting and straightening machine, comprising a support base, a slide rail connected to the top surface of the support base, a rubber plate platform slidably connected to the surface of the slide rail, a first cylinder connected to the top surface of the support base, the telescopic end of the first cylinder being connected to the rubber plate platform, a second cylinder mounted and connected to the top surface of the support base, a pneumatic switch provided on one side of the support base, a fixing block provided on the top surface of the support base, two symmetrical first guide rods connected inside the fixing block, a connecting sleeve sleeved on the surface of the first guide rods, a clamping block connected to the top end of the connecting sleeve, a servo motor installed at the bottom end inside the fixing block, a gear fixedly connected to the output shaft of the servo motor, and a toothed plate connected to the bottom end of the connecting sleeve.

[0006] In a preferred embodiment of the pneumatic yarn twisting and straightening machine of this utility model, the clamping block and the connecting sleeve are connected in an "I" shape.

[0007] In a preferred embodiment of the pneumatic yarn twisting and straightening machine of this utility model, the clamping block can form a linear reciprocating motion with the fixed block through the connecting sleeve and the first guide rod.

[0008] In a preferred embodiment of the pneumatic yarn twisting and straightening machine of this utility model, the toothed plate and the gear mesh with each other, and the connecting sleeve can be linked with the gear through the toothed plate to form a gear linkage.

[0009] As a preferred embodiment of the pneumatic yarn twisting and straightening machine of this utility model, the bottom end of the fixed block is connected to a "T"-shaped slider, the top surface of the support base is provided with a groove adapted to the slider, a second guide rod is assembled inside the groove, and a spring is sleeved on the surface of the second guide rod.

[0010] In a preferred embodiment of the pneumatic yarn twisting and straightening machine of this utility model, the slider and the slide groove are connected, the fixed block can be slidably connected to the support base through the slider and the slide groove, and the slider can be elastically telescopically connected to the second guide rod through a spring.

[0011] In a preferred embodiment of the pneumatic yarn twisting and straightening machine of this utility model, a positioning block is connected to the side wall of the fixing block, and a pressing bolt is connected through the surface of the positioning block. The fixing block can be detachably and fixedly connected to the support base through the pressing bolt and the positioning block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Through the coordinated operation of the toothed plate, gears, servo motor, clamping block, connecting sleeve, and first guide rod, one end of the wire harness is fixed. This avoids the problem of the wire harness easily slipping out of the hand when manually held. If the wire harness slips out when manually held, it not only immediately interrupts the normal twisting process but also potentially causes bending, scratching, and other damage to the already twisted portion of the wire harness, severely impacting production progress and increasing the defect rate and production costs. Furthermore, the linkage between the second guide rod, spring, slider, and groove further enhances production stability. When the twisting machine is operating, the fixed block is connected to the slider, which is placed in the groove and can move along the second guide rod. During the twisting process, if the wire harness is subjected to tension, the slider can slide within the groove, simultaneously compressing the spring. The elastic buffering effect of the spring prevents the fixed block from remaining rigidly fixed, preventing the wire harness from breaking due to excessive pulling during twisting, ensuring the integrity and stability of the wire harness during the twisting process, and improving overall product quality and production efficiency.

Detailed Implementation

[0020] 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.

[0021] Please see Figures 1-4 This utility model provides the following technical solution: a pneumatic yarn twisting and straightening machine, including a support base 1, a slide rail 2 connected to the top surface of the support base 1, a rubber plate platform 3 slidably connected to the surface of the slide rail 2, a first cylinder 4 connected to the top surface of the support base 1, the telescopic end of the first cylinder 4 connected to the rubber plate platform 3, a second cylinder 5 mounted and connected to the top surface of the support base 1, a pneumatic switch 6 provided on one side of the support base 1, a fixing block 7 provided on the top surface of the support base 1, two symmetrical first guide rods 8 connected inside the fixing block 7, a connecting sleeve 9 sleeved on the surface of the first guide rods 8, a clamping block 10 connected to the top of the connecting sleeve 9, a servo motor 11 installed at the bottom inside the fixing block 7, a gear 12 fixedly connected to the output shaft of the servo motor 11, and a toothed plate 13 connected to the bottom of the connecting sleeve 9.

[0022] Preferably, the clamping block 10 and the connecting sleeve 9 are connected in an "I" shape.

[0023] In actual use, the clamping block 10 and the connecting sleeve 9 move, and the clamping block 10 and the connecting sleeve 9 are adapted to the fixing block 7, thereby improving the stability of the movement of the clamping block 10 and the connecting sleeve 9.

[0024] Preferably, the clamping block 10 can form a linear reciprocating motion with the fixed block 7 through the connecting sleeve 9 and the first guide rod 8.

[0025] In practical use, when the connecting sleeve 9 moves along the first guide rod 8, the connecting sleeve 9 will also drive the clamping block 10 to move. Subsequently, the clamping block 10 and the connecting sleeve 9 move stably along the fixed block 7, thereby allowing the clamping block 10 and the connecting sleeve 9 to move stably through the first guide rod 8.

[0026] Preferably, the toothed plate 13 and the gear 12 mesh with each other, and the connecting sleeve 9 can form a gear linkage with the gear 12 through the toothed plate 13.

[0027] In practical use, when the servo motor 11 is connected to the power supply and started, its output shaft drives the gear 12 to rotate. Subsequently, the gear 12 drives the toothed plate 13 to move, and the movement of the toothed plate 13 drives the connecting sleeve 9 to move. Then, the connecting sleeve 9 slides smoothly along the first guide rod 8. Following this, the clamping block 10 also moves along with the connecting sleeve 9. The clamping blocks 10, which are brought closer together, then fix one end of the wire harness. This avoids the problem of the wire harness easily slipping out of the hand when manually held. If the wire harness slips out when manually held, it will not only immediately interrupt the normal twisting process, but also is very likely to cause bending, scratching, and other damage to the already twisted part of the wire harness, thus seriously affecting the production progress and increasing the defect rate and production costs.

[0028] Preferably, the bottom end of the fixing block 7 is connected to a "T"-shaped slider 14, and the top surface of the support base 1 is provided with a groove 15 that matches the slider 14. The groove 15 is fitted with a second guide rod 16, and a spring 17 is sleeved on the surface of the second guide rod 16.

[0029] In practical use, when the fixed block 7 moves, it drives the slider 14 to move as well. Simultaneously, the slider 14 slides along the groove 15, and then moves along the second guide rod 16, compressing the spring 17. Thus, if the wire harness is subjected to tension, the slider 14 can slide within the groove 15, compressing the spring 17. The elastic buffering effect of the spring 17 prevents the fixed block 7 from remaining in a rigid fixed state, preventing the wire harness from breaking due to excessive pulling during twisting. This ensures the integrity and stability of the wire harness during the twisting process, improving overall product quality and production efficiency.

[0030] Preferably, the slider 14 and the slide groove 15 are connected, the fixed block 7 can be slidably connected to the support base 1 through the slider 14 and the slide groove 15, and the slider 14 can be elastically telescopically connected to the second guide rod 16 through the spring 17.

[0031] In practical use, when the fixing block 7 is under force, it can drive the slider 14 to slide along the slide groove 15, while the slider 14 will compress the spring 17. After the wire harness is processed by the wire straightening machine, the fixing block 7 can be easily reset by the force of the spring 17.

[0032] Preferably, the side wall of the fixing block 7 is connected to the positioning block 18, and the surface of the positioning block 18 is connected through the compression bolt 19. The fixing block 7 can be detachably and fixedly connected to the support base 1 through the compression bolt 19 and the positioning block 18.

[0033] In practical use, the fixing block 7 is connected to the positioning block 18 by the compression bolt 19, and then the compression bolt 19 passes through the positioning block 18 and connects to the support base 1, thereby compressing and tightening the fixing block 7, so that the fixing block 7 can be easily fixed when it is not in use.

[0034] Working principle: First, when the servo motor 11 is connected to the power supply and started, its output shaft drives the gear 12 to rotate. Subsequently, the gear 12 drives the gear plate 13 to move, and the movement of the gear plate 13 drives the connecting sleeve 9 to move. Then, the connecting sleeve 9 slides smoothly along the first guide rod 8. Following this, the clamping block 10 also moves along with the connecting sleeve 9. The clamping blocks 10, which are brought closer together, then fix one end of the wire harness. This avoids the problem of the wire harness easily slipping out of the hand when manually held. If the wire harness detaches during manual handling, it will not only immediately interrupt the normal twisting process, but also potentially cause bending, scratching, or other damage to the already twisted portion of the wire harness, severely impacting production progress and increasing the defect rate and production costs. Next, the other end of the wire harness to be twisted rests on the rubber platform 3. Then, the pneumatic switch 6 activates the first cylinder 4 and the second cylinder 5. The second cylinder 5 then activates, its telescopic end descending to lower the fixing plate and secure the wire harness to the rubber platform 3. The first cylinder 4 then activates, its telescopic end moving the rubber platform 3 along the slide rail 2. The movement of the rubber platform 3, in conjunction with the fixing plate, straightens the twisted pair on the rubber platform 3. During the twisting process, the clamping bolt 19 is removed first. If the wire harness is under tension, the slider 14 can slide within the groove 15, simultaneously compressing the spring 17. The elastic buffering effect of spring 17 can prevent the fixing block 7 from always being in a rigid fixed state, preventing the wire harness from being torn due to excessive pulling during twisting, ensuring the integrity and stability of the wire harness during the twisting process, and improving the overall product quality and production efficiency.

[0035] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
