Description

Technical Field

[0001] The invention belongs to the technical field of bundle twisting machines, in particular to a copper conductor bundle twisting machine. Background Art

[0002] The copper conductor bundle twisting machine is a mechanical equipment specially used for twisting copper conductors. It is widely used in the fields of wire and cable manufacturing, electrical equipment manufacturing, etc. Through bundle twisting, multiple thin copper conductor wires can be tightly twisted together to form an integral wire bundle. This method can increase the total cross-sectional area of ​​the wire, thereby reducing resistance and improving conductivity.

[0003] The patent with announcement number CN209843385U discloses a copper alloy wire harness twisting machine, which relates to the field of metal wire processing equipment, including a wire harness retracting device, a wire harness guiding device and a wire harness twisting device; the wire harness retracting device includes a motor, a turntable and a wire harness disk; the output shaft end of the motor is connected to a gear; the outer surface of the turntable is surrounded by an external gear; the wire harness disk is connected to the turntable through a rotating shaft; the wire harness guiding device includes a guide tube; a pressure sensor is fixedly arranged in the middle of the inner wall of the upper end of the guide tube; the end of the pressure sensor is electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the motor. By setting a wire harness guide tube and setting a pressure sensor in the center of the wire harness guide tube; by comparing the pressure value when the wire harness is tightened with the standard value, and then controlling the rotation direction of the motor output shaft through the controller, the wire harness is automatically retracted or released, and the tension required for the wire harness twisting is ensured.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] The wire harness is twisted by fixing both ends of the wire harness and then driving the wire harness to release and rotate at the same time. After the twisting is completed, the wire harness is removed. However, when the number of wire harness groups to be twisted is large, workers are required to frequently manually remove the twisted wire harnesses, which not only increases the labor intensity of the workers, but also the removed wire harnesses may be placed on the base in a relatively messy state, which may easily cause multiple groups of wire harnesses to be entangled with each other, which is not conducive to the subsequent unified transportation of the wire harnesses. In addition, in some cases, after all the wire harnesses are twisted, workers are required to check the twisting quality of each group of wire harnesses to determine whether they are qualified. Unqualified wire harnesses need to be twisted again. When the wire harnesses are placed around in a messy manner, it is not conducive to the staff to check the twisting quality of the wire harnesses, and confusion is easy to occur. When the workers manually organize the wire harnesses, the labor intensity will be increased, and the subsequent bundle twisting work will be affected. Especially for some shorter wire harnesses, the twisting time is shorter, which also increases the frequency of workers removing and arranging the wire harnesses.

[0006] To this end, the present invention provides a copper conductor bundle twisting machine. Summary of the invention

[0020] 1. The copper conductor bundle twisting machine described in the present invention utilizes an anti-winding placement mechanism. Whenever a group of copper wires is twisted, the terminal blocks will fall onto the placement seat for placement, eliminating the need for workers to manually remove each group of twisted copper wires, reducing the labor intensity of workers, and each group of copper wires is placed separately without being entangled with each other, which is convenient for subsequent unified transportation. In addition, after a certain amount of terminal blocks are placed on the placement seat, the adjustment rod can be driven to slide on the slide bar three to move from the terminal block to the end of the copper wire. During this process, the support plate lifts the copper wire. When the support plate is at the end position of the copper wire, the copper wire is in a straight state. At this time, the twisting quality of the copper wire can be observed again, which can avoid the situation where the twisting quality is difficult to observe due to the bending of the copper wire. At the same time, it also has a combing effect on the copper wire, further avoiding The entanglement of copper wires is avoided, and since multiple groups of copper wires are uniformly placed straight and in a uniform orientation, it is also convenient to compare the copper wires during quality inspection, thereby improving inspection efficiency, making it easy to find unqualified copper wires and twist them again, thereby avoiding the unqualified copper wires from being put into subsequent use. Moreover, whenever a terminal is about to fall onto the placement seat, the pressing rod is driven to press the terminal tightly, and during quality inspection, multiple placement seats are driven to rotate. When the placement seats rotate, the copper wires will also rotate accordingly, and the copper wires are supported by the support plate, so the copper wires will rotate on the support plate. At this time, workers do not need to move their sights frequently to observe various positions of the copper wires, thereby making it easier to inspect the twisting quality of the copper wires, avoiding visual fatigue caused by frequent movement of the sights, and further improving inspection efficiency.

[0021] 2. The copper conductor bundle twisting machine described in the present invention further ensures the stability of the second clamping plate when clamping the copper conductor by providing an anti-slip texture on one side of the second clamping plate, thereby avoiding the situation where the twisting effect is affected by the deviation of the copper conductor.

[0041] A worm gear 19 is fixedly connected to one end of the placement seat 28, and the worm gear 19 is rotatably set on the mounting plate 15. A rotating shaft 20 is rotatably set at both ends of one side of the mounting plate 15. A plurality of worm teeth 31 are sleeved and fixedly connected to the rotating shaft 20.

A motor 26 is fixedly connected to one end of the upper side of the mounting plate 15, and the output end of the motor 26 is fixedly connected to one end of the rotating shaft 20.

[0042] One side of the support plate 12 is slidably connected to two slide rods 2 17 , one end of the slide rod 2 17 is fixedly connected to a rack 18 , and one side of the support plate 12 is fixedly connected to an electric push rod 2 16 , the piston end of the electric push rod 2 16 is fixedly connected to one end of the rack 18 .

[0043] A gear 29 is sleeved and fixedly connected to the rear end of the clamping shaft 37, and a torsion spring 30 is sleeved on the front end of the clamping shaft 37.

A plurality of notches are provided on the mounting plate 15, and the rack 18 can pass through the notches, and the tooth blocks on the rack 18 are meshed with the gear 29.

[0044] Specifically, when the existing bundle twisting machine is in use, the two ends of the wire harness are fixed, and then the wire harness is driven to release and rotate at the same time to achieve the bundle twisting of the wire harness. After the twisting is completed, the wire harness is removed. However, when the number of wire harness groups to be twisted is large, workers are required to frequently manually remove the twisted wire harnesses, which not only increases the labor intensity of the workers, but also the removed wire harnesses may be placed on the base in a relatively messy state, and multiple groups of wire harnesses are prone to entanglement with each other, which is not conducive to the subsequent unified transportation of the wire harnesses. In addition, in some cases, after all the wire harnesses are twisted, workers are required to check the twisting quality of each group of wire harnesses to determine whether they are qualified. Unqualified wire harnesses need to be twisted again. When the wire harnesses are placed in a messy manner around, it is not conducive to the staff to check the twisting quality of the wire harnesses, and confusion is prone to occur. When the workers manually organize the wire harnesses, the labor intensity will also be increased, and the subsequent bundle twisting work will be affected. Especially for some shorter wire harnesses, the twisting time is shorter, and the frequency of workers removing and arranging the wire harnesses is correspondingly increased;

[0045] Therefore, when this embodiment is used, it is used for the situation that multiple copper wires are fixed on one connecting terminal together. After the twisting is completed, the connecting terminal can be connected to other devices, such as cables, circuit boards or electrical components. The connecting terminal is placed between two clamping plates 14, and then the motor 4 11 is used to drive the two-way threaded rod 12 to rotate, so that the two clamping plates 14 are close to each other to clamp the connecting terminal. Then, the end of the copper wire away from the connecting terminal is placed between two clamping plates 2 33, and the motor 6 32 drives the two-way threaded rod 2 34 to rotate, so that the two clamping plates 2 33 are driven to approach each other to clamp the end of the copper wire. Then, the motor 13 and the electric push rod 15 are started at the same time. The motor 13 drives the turntable 13 to rotate to rotate the connecting terminal. At the same time, the electric push rod 15 drives the turntable 2 36 to approach the turntable 13. In this process, the copper wires are twisted together. When twisting is completed, the clamping plate 14 and the clamping plate 2 33 are driven to move away from the terminal and the copper wire, and the clamping plate 14 is driven to rotate 90 degrees so that the terminal can fall off, and the terminal falls on the placement seat 28, which is received by the placement seat 28. Similarly, the copper wire also falls off from the clamping plate 2 33. At this time, the worker can fix the next group of copper wires and carry out the twisting work. Moreover, every time a terminal falls on the placement seat 28, the motor 3 10 drives the threaded rod 1 9 to rotate, so that the mounting plate 15 slides, so that the placement seats 28 at different positions are under the clamping plate 1 14, and then repeat the above operation to realize the placement of multiple groups of twisted terminal blocks, thereby eliminating the process of workers manually removing each group of twisted copper wires, reducing the labor intensity of workers, and each group of copper wires is placed separately, so that they will not be entangled with each other, which is convenient for subsequent unified transportation.

[0046] Furthermore, after the terminal block falls onto the placement seat 28, its copper wire portion may be bent due to the drooping, which is not conducive to observing the twisting quality of the copper wire. Therefore, after a certain amount of terminal blocks are placed on the placement seat 28, the motor 5 21 is used to drive the threaded rod 22 to rotate, so that the adjusting rod 24 slides on the sliding rod 3 23 to move from the terminal block to the end of the copper wire. In this process, the support plate 25 holds up the copper wire. When the support plate 25 is at the end of the copper wire, the copper wire is in a straight state. At this time, the twisting quality of the copper wire is observed again, which can avoid the situation that the twisting quality is difficult to observe due to the bending of the copper wire. At the same time, it also plays a combing role on the copper wire, further avoiding the entanglement of the copper wires. Moreover, since multiple groups of copper wires are uniformly placed straight and in a uniform orientation, it is also convenient to compare the copper wires with each other during quality inspection, thereby improving the inspection efficiency, making it easy to find unqualified copper wires, and twist the unqualified copper wires again, thereby avoiding the unqualified copper wires from being put into subsequent use.

[0047] When workers inspect the quality of the twisted copper wires, in order to inspect more comprehensively, they need to observe all directions of the copper wires. When the copper wires are placed on the support plate 25, the workers need to frequently move their sight lines to achieve a full-scale inspection, which is troublesome and easily causes visual fatigue. Therefore, in order to avoid this problem, whenever a terminal is about to fall onto the placement seat 28, the electric push rod 16 drives the rack 18 to move, so that the rack 18 passes through the notch on the mounting plate 15 and meshes with the gear 29, so that the gear 29 and the clamping shaft 37 rotate, and the torsion spring 30 is deformed. At this time, the end of the lower pressure rod 27 is away from the placement seat 28, and the terminal can fall into the placement seat 28 smoothly. Then the rack 18 is reset, and the lower pressure rod 27 can press the terminal under the action of the torsion spring 30. During the quality inspection, the motor 26 can be used to drive the rotating shaft 20 to rotate, so that the multiple groups of worm teeth 31 on the rotating shaft 20 drive the multiple worm wheels 19 to rotate simultaneously, so that the placement seat 28 rotates. When the placement seat 28 rotates, the copper wire will also rotate accordingly, and the copper wire is supported by the support plate 25. Therefore, the copper wire will rotate on the support plate 25. At this time, the worker does not need to move his line of sight frequently to observe the various positions of the copper wire, which makes it easier to inspect the twisting quality of the copper wire, avoids visual fatigue caused by frequent movement of the line of sight, and further improves the inspection efficiency.

[0048] In this embodiment, Figure 8 As shown, one side of the second clamping plate 33 is provided with an anti-slip texture 35 .

[0049] Specifically, by providing an anti-slip texture 35 on one side of the second clamping plate 33, the stability of the second clamping plate 33 when clamping the copper wire is further ensured, thereby avoiding the situation where the twisting effect is affected by the deviation of the copper wire.

[0050] Working principle: the connection terminal is placed between two clamping plates 14, and then the motor 4 11 is used to drive the two-way threaded rod 12 to rotate, so that the two clamping plates 14 are brought close to each other to clamp the connection terminal, and then the end of the copper wire away from the connection terminal is placed between the two clamping plates 2 33, and the motor 6 32 drives the two-way threaded rod 2 34 to rotate, so as to drive the two clamping plates 2 33 to approach each other to clamp the end of the copper wire. By providing an anti-slip texture 35 on one side of the clamping plate 2 33, the stability of the clamping plate 2 33 when clamping the copper wire is further guaranteed, and the situation that the twisting effect is affected by the deviation of the copper wire is avoided; then the motor 13 and the electric push rod 15 are started at the same time, and the motor 13 drives the turntable 13 Rotate to rotate the connecting terminal. At the same time, the electric push rod 15 drives the turntable 2 36 to approach the turntable 13. In this process, the copper wires are twisted together. When the twisting is completed, the clamping plate 14 and the clamping plate 2 33 are driven away from the terminal and the copper wire, and the clamping plate 14 is driven to rotate 90 degrees so that the terminal can fall, and the terminal falls onto the placement seat 28, which is received by the placement seat 28. Similarly, the copper wire also falls off from the clamping plate 2 33. At this time, the worker can fix the next group of copper wires and perform the twisting work. Moreover, every time a terminal falls onto the placement seat 28, the motor 3 10 drives the threaded rod 1 9 to rotate, so that the mounting plate 15 slides, so that the placement seats 28 at different positions The copper wires of the plurality of groups of the plurality of terminals are placed under the clamping plate 14, and then the above operation is repeated to realize the placement of the plurality of groups of the twisted copper wires, thereby eliminating the need for workers to manually remove each group of the twisted copper wires, reducing the labor intensity of the workers, and each group of the copper wires is placed separately, so that they will not be entangled with each other, which is convenient for subsequent unified transportation; and, since the copper wire parts of the terminals may be bent due to the drooping after falling onto the placement seat 28, it is not conducive to observing the twisting quality of the copper wires. Therefore, after a certain amount of the terminals are placed on the placement seat 28, the motor 5 21 is used to drive the threaded rod 22 to rotate, so that the adjusting rod 24 slides on the sliding rod 3 23, so as to adjust the terminals from the wiring seat 28. The copper wire is moved to the end of the copper wire. During this process, the support plate 25 holds up the copper wire. When the support plate 25 is at the end of the copper wire, the copper wire is in a straight state. At this time, the twisting quality of the copper wire can be observed again, which can avoid the situation that the twisting quality is difficult to observe due to the bending of the copper wire. At the same time, it also plays a combing role on the copper wire, further avoiding the entanglement of the copper wires with each other. Moreover, since multiple groups of copper wires are uniformly placed straight and in a uniform orientation, it is also convenient to compare the copper wires with each other during quality inspection, thereby improving the inspection efficiency, making it easy to find unqualified copper wires, and twist the unqualified copper wires again, thereby avoiding the unqualified copper wires from being put into subsequent use.When workers inspect the quality of the twisted copper wires, in order to inspect more comprehensively, they need to observe all directions of the copper wires. When the copper wires are placed on the support plate 25, the workers need to frequently move their sight lines to achieve a full-scale inspection, which is troublesome and easily causes visual fatigue. Therefore, in order to avoid this problem, whenever a terminal is about to fall onto the placement seat 28, the electric push rod 16 drives the rack 18 to move, so that the rack 18 passes through the notch on the mounting plate 15 and meshes with the gear 29, so that the gear 29 and the clamping shaft 37 rotate, and the torsion spring 30 is deformed. At this time, the end of the lower pressure rod 27 is away from the placement seat 28, and the terminal can fall into the placement seat 28 smoothly. Then the rack 18 is reset, and the lower pressing rod 27 can press the terminal under the action of the torsion spring 30. During the quality inspection, the motor 26 can be used to drive the rotating shaft 20 to rotate, so that the multiple groups of worm teeth 31 on the rotating shaft 20 drive the multiple worm wheels 19 to rotate simultaneously, so that the placement seat 28 rotates. When the placement seat 28 rotates, the copper wire will also rotate accordingly, and the copper wire is supported by the support plate 25, so the copper wire will rotate on the support plate 25. At this time, the worker does not need to move his sight frequently to observe the various positions of the copper wire, which makes it easier to inspect the twisting quality of the copper wire, avoids visual fatigue caused by frequent movement of the sight, and further improves the inspection efficiency. ;
