Description

Technical Field

[0001] The invention relates to the technical field of detecting the torsion angle of continuous wires during transportation, and in particular to an automatic intermittent detection device for wire torsion. 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 technicians in this field to develop an automatic intermittent wire torsion detection device that can measure the torsion of the wire during the continuous conveying of the wire.

[0027] Figure 2 It is a schematic top view of an embodiment of the present invention.

[0028] like Figure 1 and Figure 2As shown, this embodiment provides a method for detecting the torsion angle of a continuous wire during transportation, by setting two sets of stabilizing rollers to fix the continuous wire into a straight line, and by fixing a rotating disk with an output shaft and an automatic chuck on the continuous wire and setting a follow-up sliding detection frame on the outside of the rotating disk, and setting an encoder and a transmission shaft on the sliding detection frame, the rotating disk is driven to rotate by the torsion of the continuous wire, and the encoder is used to identify the position of the rotating disk through the transmission of the transmission connection device to identify and read the torsion of the continuous wire. The technical solution is simple in structure and easy to operate. 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.

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 to the base dd through the four brackets.

[0031] Figure 5 It is a schematic cross-sectional view of a slide chute hc according to an embodiment of the present invention.

[0032] Figure 6 It is a cross-sectional schematic diagram of a JS embodiment of the present invention.

[0033] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the sliding detection device j is also provided with a sliding detection frame jz and a rotating disk xz, the sliding detection frame jz is installed on the symmetrical sliding frame h and can slide on the symmetrical sliding frame h in parallel to the conveying direction of the continuous wire xc. The rotating disk xz is rotationally connected to the sliding detection frame jz and is also provided with an output shaft xzs with a hole in the center for the continuous wire xc to pass through, the sliding detection frame jz is also provided with an encoder bb and a transmission shaft cd connected to each other, and the rotation center axis of the rotating disk xz is parallel to the rotation center axis of the transmission shaft cd. The output shaft xzs is also fixedly provided with an output gear xzsz arranged coaxially therewith, and the transmission shaft cd is also fixedly provided with a speed measuring gear cdz arranged coaxially therewith, and the output gear xzsz and the speed measuring gear cdz are mutually transmitted through a gear pair so that the transmission shaft cd rotates synchronously with the rotating disk xz. The encoder bb is fixedly arranged on the sliding detection frame jz and can rotate coaxially with the transmission shaft cd. The encoder bb can calculate the rotation angle of the output shaft xzs by rotating.

[0034] The rotating disk xz is also provided with an automatic chuck xzk, which can automatically clamp or release the continuous wire xc so that the rotating disk xz and the continuous wire xc are fixed or separated from each other. The automatic chuck xzk is also provided with a gripper xzkk and a bevel gear plate xzkc, and the side of the output shaft xzs is also provided with an end face d. Three grippers xzkk are arranged and evenly arranged on the end face d of the output shaft xzs. Three evenly arranged slide grooves hc are also arranged on the end face d. The gripper xzkk is also provided with a slider hk. The gripper xzkk is placed in the slide groove hc and the sliding fit between the slide groove hc and the slider hk enables the gripper xzkk to slide relative to the output shaft xzs. Among them, the extension direction of the slide groove hc is toward the rotation center of the output shaft xzs, and the sliding direction of the clamping gripper xzkk is also toward the rotation center of the output shaft xzs. When the three clamping grippers xzkk slide synchronously toward the rotation center of the output shaft xzs, they can clamp the continuous wire xc passing through the central hole of the rotating disk xz.

[0035] Among them, the bevel gear disk xzkc is coaxial with the output gear xzsz and is rotatably installed on the output shaft xzs. The bevel gear disk xzkc is also provided with a bevel groove xoc. The slider hk on the clamping gripper xzkk is also provided with a roller g. The roller g is placed in the bevel groove xoc and slides. The rotation of the bevel gear disk xzkc can drive the bevel groove xoc to rotate synchronously. The rotation of the bevel groove xoc can drive the slider hk to slide in the slide groove hc, thereby driving the clamping gripper xzkk to approach or move away from the continuous wire xc.

[0036] Among them, a sliding helical gear hdc is also provided on the transmission shaft CD. The sliding helical gear hdc is installed on the transmission shaft CD through a sliding key and can slide on the transmission shaft CD. The sliding helical gear hdc can mesh with the helical gear plate xzkc for transmission and when the sliding helical gear hdc slides on the transmission shaft CD, since the tooth shape on its outer surface is a helical tooth shape, the sliding of the sliding helical gear hdc can cause the helical gear plate xzkc to rotate relative to the output gear xzsz.

[0037] According to one aspect of the specific implementation of the embodiment of the present invention, a connector js is provided on the end face d of the output shaft xzs, and a docking shaft djz is provided at one end of the output shaft xzs and is interconnected with the connector js, and the docking shaft djz is connected to the sliding detection frame jz by rotation.

[0038] According to one aspect of the specific implementation of the embodiment of the present invention, a shift fork bbc is also provided on the sliding detection frame jz, and the shift fork bbc is inserted into the outer side of the sliding helical gear hdc. The shift fork bbc is connected to the sliding detection frame jz through an oil cylinder. The shift fork bbc is driven to move left and right through the telescopic action of the oil cylinder, and the sliding helical gear hdc can be driven to slide on the transmission shaft cd.

[0042] Fig.10 It is a schematic diagram of releasing the continuous wire xc according to an embodiment of the present invention.

[0043] like Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, according to one aspect of the specific implementation of an embodiment of the present invention, when the production line needs to detect the torsion amount of the continuous wire xc, the sliding detection device j actively or passively generates movement synchronized with the continuous wire xc, and then the oil cylinder generates a telescopic action to make the shift fork bbc shift the sliding helical gear hdc to slide on the transmission shaft cd, thereby indirectly driving the bevel gear plate xzkc to rotate relative to the output gear xzsz, thereby driving the three clamps xzkk to synchronously slide toward the rotation center of the output shaft xzs to clamp the continuous wire xc passing through the central hole of the rotating disk xz, so that the rotating disk xz generates a rotation synchronized with the continuous wire xc, and at the same time, the output gear xzsz generates a rotation synchronized with the continuous wire xc, thereby driving the speed measuring gear cdz to rotate, and finally the torsion amount of the continuous wire xc is calculated by the encoder bb. Then the oil cylinder produces the opposite telescopic action, causing the shift fork bbc to shift the sliding helical gear hdc to slide on the transmission shaft cd, indirectly driving the bevel gear plate xzkc to rotate relative to the output gear xzsz, thereby driving the three grippers xzkk to synchronously slide in the direction opposite to the rotation center of the output shaft xzs, releasing the continuous wire xc passing through the central hole of the rotating disk xz, so that the rotating disk xz is separated from the continuous wire xc, and then the sliding detection device j actively or passively produces a deceleration action and finally stops moving, and the detection process ends.

The scope of protection of the present invention is defined by its claims and covers all embodiments and obvious equivalent variations falling within its scope.
