Description
Technical Field
[0001] The utility model relates to the technical field of detecting the torsion angle of continuous wires during transportation, in particular to a synchronous wheel wire torsion detection device. Background Art
[0002] A wire outer surface grinder is a device that can continuously grind the outer surface of a wire to remove surface defects of the wire during the continuous online conveying process. Usually, a wire outer surface grinder is provided with multiple grinding wheels that rotate at high speed along the wire conveying direction, and usually multiple grinding wheels are arranged in pairs in the wire conveying direction. Such a wire outer surface grinder is usually suitable for processing relatively static wires that are continuously conveyed and have no self-twist. In this way, the grinding position of each pair of grinding wheels is usually a fixed position on the circumference of the wire. If the continuous wire is twisted due to its own stress during the conveying process, the grinding position of each pair of grinding wheels will deflect as the wire twists, which causes the grinding wheel to gradually deviate from the preset grinding position during the grinding process. In order to solve this problem, it is necessary to measure the amount of torsion generated by the continuous wire during the conveying process, and then correct the grinding position of the grinding wheel according to the torsion to make the wire outer surface grinder adapt to various wire grinding conditions. Therefore, it has become an inevitable trend for technical personnel in this field to develop a synchronous wheel wire torsion detection device that can measure the torsion of the wire during the continuous conveying of the wire.

[0026] like Figure 1 , Figure 2 and Figure 3As shown, this embodiment provides a synchronous wheel wire torsion detection device capable of detecting the torsion angle generated by the continuous wire during transportation. The continuous wire is fixed into a straight line by setting two sets of stabilizing rollers, and the synchronous wheel assembly provided with a clamping wheel and a speed measuring wheel is pressed on the continuous wire. A rotary encoder is set at the coaxial end of the speed measuring wheel to measure the rotation speed of the speed measuring wheel to indirectly calculate the torsion amount of the continuous wire. This technical solution is simple, convenient, low-cost, and conducive to practice. Its specific structure in a specific embodiment may include a first stabilizing roller group wd1 and a second stabilizing roller group wd2 arranged in pairs and spaced a certain distance from each other for fixing the continuous wire xc, and the continuous wire xc passes through the first stabilizing roller group wd1 and the second stabilizing roller group wd2 and maintains a straight line between the two. The first stabilizing roller group wd1 and the second stabilizing roller group wd2 are arranged in parallel and are both arranged on the base dd below them. A symmetrical sliding frame h and a sliding detection device j are also provided along the conveying direction of the continuous wire xc, wherein the symmetrical sliding frame h is provided with two sliding rods hg arranged in parallel to each other, the two sliding rods hg arranged in parallel to each other are arranged on both sides of the continuous wire xc and the two sliding rods hg arranged in parallel to each other are parallel to the conveying direction of the continuous wire xc. The two sliding rods hg are respectively mounted on four brackets and fixed on the base dd through the four brackets.
[0027] Among them, the sliding detection device j is also provided with a sliding detection frame jz and a synchronous wheel assembly tb. The sliding detection frame jz is arranged in a U shape and the two sides of its upper end are respectively provided with sliding holes that can slide with the sliding rod hg. The sliding detection frame jz is installed on the symmetrical sliding frame h through the sliding cooperation between the sliding rod hg and the sliding hole and can slide on the symmetrical sliding frame h in parallel to the conveying direction of the continuous wire xc.
[0028] The synchronous wheel assembly tb is mounted inside the U-shaped sliding detection frame jz. The synchronous wheel assembly tb is also provided with a clamping wheel yj and a speed measuring wheel cs, both of which can rotate freely. The clamping wheel yj and the speed measuring wheel cs are respectively arranged on both sides of the continuous wire xc, and their rotation center lines are parallel to the conveying direction of the continuous wire xc. An encoder bb and a transmission shaft cd are also provided, which are connected to each other. The speed measuring wheel cs is coaxially fixed with the transmission shaft cd. When the speed measuring wheel cs rotates, the transmission shaft cd can transmit the torque to the encoder bb, and the encoder bb can rotate synchronously with the transmission shaft cd to measure and calculate the rotation speed of the speed measuring wheel cs.
[0029] Wherein, a pressure wheel device yp is provided below the synchronous wheel assembly tb, and the pressure wheel yj and the speed measuring wheel cs are respectively connected to the pressure wheel device yp and can press or separate from the continuous wire xc under the action of the pressure wheel device yp.

The telescopic fork ssc is arranged in a Y shape and is provided with two mutually symmetrical pull-and-pull rods at its first end. The two pull-and-pull rods are both rotatably connected to a telescopic rod arranged below them. The telescopic rod and the two pull-and-pull rods form a telescopic fork ssc capable of performing telescopic movements.

[0034] like Figure 4 , Figure 5 and Figure 6As shown, according to one aspect of the specific implementation of the first embodiment of the utility model, its specific working process is that first, the sliding detection device j starts to accelerate from static to the right to the same speed as the continuous wire xc, and then the telescopic cylinder ss performs a contraction action to pull the telescopic fork ssc downward, and synchronously, the clamping swing rod yjb and the speed measuring swing rod csb respectively drive the clamping wheel yj and the speed measuring wheel CS at their ends to approach each other and clamp the continuous wire xc so that the clamping wheel yj and the speed measuring wheel CS produce a synchronous rotation action with the continuous wire xc. The encoder bb indirectly obtains the torsion angle of the continuous wire xc by measuring the rotation speed of the speed measuring wheel CS. After the measurement is completed, the telescopic cylinder ss performs an extension action to push the telescopic fork ssc upward, and synchronously, the clamping swing rod yjb and the speed measuring swing rod csb respectively drive the clamping wheel yj and the speed measuring wheel CS at their ends to move away from each other and detach from the continuous wire xc. Then the sliding detection device j gradually decelerates to static, and then returns to the original starting position, and the detection process is completed.

[0036] Figure 8 It is a schematic side view of the clamping of the synchronous wheel assembly TB of the second embodiment of the utility model.
[0037] like Figure 7 and Figure 8 As shown, according to one aspect of the specific implementation of the second embodiment of the utility model, the specific technical feature that distinguishes it from the first embodiment is that the middle parts of the clamping rocker yjb and the speed measuring rocker csb are respectively hinged to the sliding detection frame jz, and the second ends of the clamping rocker yjb and the speed measuring rocker csb are respectively hinged to the telescopic cylinder ss. The pressure wheel device yp is also provided with a balancing component p, and the balancing component p is also provided with two balancing springs tp and an adjustment block tk, the two balancing springs tp are symmetrically arranged on both sides of the adjustment block tk, and the outer ends of the two balancing springs tp relative to the adjustment block tk are respectively connected to the clamping rocker yjb and the speed measuring rocker csb. The adjusting block tk is arranged on the sliding detection frame jz through the sliding pair. Through the action of the sliding pair, the adjusting block tk can move to the left or right to generate a pressure difference between the two balancing springs tp. The corresponding clamping rocker arm yjb and the speed measuring rocker arm csb will produce a swinging motion to maintain the elastic balance of the two balancing springs tp, thereby adjusting the positions of the clamping wheel yj and the speed measuring wheel cs to keep them symmetrical relative to the center of the continuous wire xc.
[0038] According to one aspect of the specific implementation of the second embodiment of the utility model, its specific working process is that first, the sliding detection device j starts to accelerate from rest to the right to the same speed as the continuous wire xc, and then the telescopic cylinder ss extends, and synchronously, the clamping swing rod yjb and the speed measuring swing rod csb respectively drive the clamping wheel yj and the speed measuring wheel CS at their ends to approach each other and clamp the continuous wire xc so that the clamping wheel yj and the speed measuring wheel CS produce synchronous rotation with the continuous wire xc. The encoder bb indirectly obtains the torsion angle of the continuous wire xc by measuring the rotation speed of the speed measuring wheel CS. After the measurement is completed, the telescopic cylinder ss retracts, and synchronously, the clamping swing rod yjb and the speed measuring swing rod csb respectively drive the clamping wheel yj and the speed measuring wheel CS at their ends to move away from each other and detach from the continuous wire xc. Then the sliding detection device j gradually decelerates to rest, and then returns to the original starting position, and the detection process is completed.
