Description

Technical Field

[0001] The present invention relates to the technical field of inner circumference measurement of wire rings, and particularly relates to an automatic detection device and detection method for wire rings. Background Art

[0002] For the inner circumference measuring machine of a tire wire ring, when measuring the inner diameter of a tire, after the wire ring is expanded by a measuring upper ring plate and a measuring lower ring plate, the distance between the upper ring plate and the lower ring plate is increased by a cylinder and a chain mechanism, and then the distance between the upper ring plate and the lower ring plate is detected by a travel detector to obtain the inner diameter of the coil.

[0003] However, in the existing technology, first, when measuring, the wire ring needs to be manually placed within a general range for measurement. However, the maximum value of the distance during measurement is limited, and it often occurs that the actual circumference during measurement is greater than the values of the upper ring plate and the lower ring plate it is sleeved on. Therefore, it is necessary to remove the wire ring and try on it multiple times, which also has a certain impact on the measurement of the actual accuracy. Therefore, the present invention provides an automatic detection device and detection method for wire rings. Summary of the Invention

[0004] In view of the above existing problems, the present invention is proposed.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] An automatic detection device and detection method for wire rings, including a measuring machine main body. One side of the top of the measuring machine main body is provided with a measuring machine control panel. A measuring platform is provided on the inclined side of the measuring machine main body. A measuring upper ring plate and a measuring lower ring plate are installed on the surface of the measuring platform. A spacing groove is provided between the measuring upper ring plate and the measuring lower ring plate. On both sides of the bottom end of the spacing groove between the measuring upper ring plate and the measuring lower ring plate of the measuring machine main body, a wire ring taking device is installed. The wire ring taking device includes a main body shell. An activity groove is provided at the top of the main body shell. An outer ring threaded rod is installed at the bottom end of the main body shell in the activity groove. An inner ring threaded rod is installed on one side of the main body shell where the outer ring threaded rod is located. On one side of the outer ring threaded rod and the inner ring threaded rod, there is an inner ring threaded ring, and on the other side, there is an outer ring threaded ring. The inner ring threaded ring is provided with a threaded groove on the inner side of one side of the inner ring threaded rod. The inner ring threaded ring is movably connected to the outer ring threaded rod on one side of the outer ring threaded rod. The top end of the inner ring threaded ring on one side of the outer ring threaded rod is fixedly connected to an inner ring rod. The outer ring threaded ring is provided with a threaded groove on the inner side of one side of the outer ring threaded rod. The outer ring threaded ring is movably connected to the inner ring threaded rod on one side of the inner ring threaded rod. The top end of the outer ring threaded ring on one side of the outer ring threaded rod is fixedly connected to an outer ring rod.

[0007] Further, an inner ring clamping groove is formed at one end of the inner ring threaded rod located at the outer ring threaded ring. An outer ring clamping groove is formed at one end of the outer ring threaded rod located at the outer ring threaded ring. An outer ring gear rod is installed on one side of the main body housing where the outer ring clamping groove is located. An outer ring large gear is fixedly connected to the middle of the outer ring gear rod. An outer ring clamping block is fixedly connected to the outer ring gear rod near the outer ring clamping groove. The outer ring clamping block is movably clamped with the outer ring clamping groove. An inner ring gear rod is installed on one side of the main body housing where the inner ring clamping groove is located. An inner ring large gear is fixedly connected to the middle of the inner ring gear rod. An inner ring clamping block is fixedly connected to the inner ring gear rod near the inner ring clamping groove. The inner ring clamping block is movably clamped with the inner ring clamping groove.

[0008] Further, magnets are fixedly connected to both the inner ring gear rod and the outer ring gear rod on the side away from the outer ring threaded ring. An inner ring electromagnet is installed at the position of the main body housing where the inner ring gear rod is away from the outer ring threaded ring. An outer ring electromagnet is installed at the position of the main body housing where the outer ring gear rod is away from the outer ring threaded ring. A clamping motor is installed between the outer ring large gear and the inner ring large gear of the main body housing. An output gear is fixedly connected to the output shaft of the clamping motor. The clamping motor is drivingly connected to the outer ring large gear and the inner ring large gear through the output gear. When the outer ring electromagnet and the inner ring electromagnet are activated, they will eject the outer ring gear rod and the inner ring gear rod, so that the outer ring clamping block and the inner ring clamping block are clamped into the corresponding outer ring clamping groove and inner ring clamping groove.

[0009] Further, a lifting groove is formed on the side of the outer ring rod close to the inner ring rod. A cap is fixedly connected to the top of the outer ring rod. A lifting block is movably clamped in the lifting groove of the outer ring rod. A rotating groove is formed between the top of the outer ring rod and the cap. A pulley is installed in the rotating groove. A lifting motor is fixedly installed at the top of the outer ring threaded ring on one side of the inner ring threaded rod. A winding shaft is fixedly connected to the output shaft of the lifting motor. Pulling rope grooves are formed on both sides of the top of the outer ring rod where the rotating groove is located. One end of a pulling rope is fixedly connected to the top of the lifting groove. The other end of the pulling rope passes through the pulling rope groove away from the lifting groove and is fixedly connected to the winding shaft of the lifting motor.

[0010] Further, the inner ring rods and the outer ring rods on both sides of the upper measuring ring plate are made of conductive metal materials. After the inner ring rods are electrically connected, the power switch of the inner ring electromagnet is controlled. After the outer ring rods are electrically connected, the power switch of the outer ring electromagnet is controlled. When adjacent outer ring rods and inner ring rods are electrically connected, the power switch of the lifting motor is turned on.

[0011] Further, a closing switch for the inner ring rod and the outer ring rod is provided at the control panel of the measuring machine. When the outer ring rod and the outer ring rod, the inner ring rod and the outer ring rod, and the inner ring rod and the inner ring rod are all in a power-off state, the return operation will be controlled until the inner ring rod and the outer ring rod are in an open state. Touch switches are installed at both ends of the inner side of the slot of the movable slot. The outer ring electromagnet is controlled to cut off power at the outer ring rod, and the inner ring electromagnet is controlled to cut off power at the inner ring rod.

[0012] An automatic detection method for bead wires includes the following steps:

[0013] S1. When in use, first keep the inner ring rod and the outer ring rod in an open state. At this time, measure the inner circumference of the bead wire. Then, put the tire bead wire on a rough position. At this time, the machine controls the upper measuring ring plate and the lower measuring ring plate to stretch the distance between the spacing slots. The inner circumference of the bead wire is the sum of the semi-circular rings of the upper measuring ring plate and the lower measuring ring plate plus twice the distance between the spacing slots. When measuring, if the inner circumference diameters of the upper measuring ring plate and the lower measuring ring plate at the position where the bead wire is placed differ greatly, the closing switch of the inner ring rod and the outer ring rod is activated.

[0014] S2. When the closing switch is turned on, the outer ring electromagnet and the inner ring electromagnet are activated, generating magnetic force and then repulsive force, which causes the inner ring catch to be inserted into the inner ring slot and the outer ring catch to be inserted into the outer ring slot. At this time, the clamping motor starts to rotate, causing the inner ring large gear and the outer ring large gear to rotate, and the outer ring rod and the inner ring rod on the same main body shell start to approach each other. When two of the outer ring rods or two of the inner ring rods first touch the bead wire, a closed circuit is formed, causing the corresponding outer ring electromagnet or inner ring electromagnet to cut off power, so that the outer ring gear rod or the inner ring gear rod is disengaged from the clamped state, and the outer ring threaded rod or the inner ring threaded rod stops rotating.

[0015] S3. After one of them stops rotating, the other continues to rotate until a closed loop is formed between the outer ring rod and the inner ring rod. At this time, the lifting motor is energized, and the winding shaft of the lifting motor rotates. When the winding shaft rotates, the tension rope inside the outer ring rod is pulled. As the tension rope is pulled, the lifting block at the bottom of the outer ring rod is pulled to move towards the top of the outer ring rod, pulling the bead wire upward until it reaches the maximum pulling range. At this time, the bead wire taking operation is completed. After taking out the bead wire;

[0016] S4. At this time, it is in a power-off state. The inner ring electromagnet and the outer ring electromagnet push the inner ring clamping block and the outer ring clamping block into the corresponding outer ring card slots and inner ring card slots. At this time, the clamping motor performs a return operation, thereby pulling back the outer ring rod and the inner ring rod. When the outer ring rod contacts the side of the maximum distance between the two ends of the movable slot, the pressing switch is triggered. At this time, the outer ring electromagnet is powered off. When the inner ring rod contacts the side of the maximum distance between the two ends of the movable slot, the pressing switch is triggered. At this time, the inner ring electromagnet is powered off, thus returning to the initial state. At this time, the measurement operation continues.

[0017] In the above technical solution, the technical effects and advantages provided by the present invention are as follows:

[0018] 1. The present invention realizes the precise measurement of the inner circumference of the steel wire ring and automatic wire taking through machine control and automated components such as electromagnets, greatly improving work efficiency. At the same time, in traditional operations, workers need to directly contact the steel wire ring and measuring tools, which poses certain safety hazards. Through automated operations, the direct contact between workers and the steel wire ring is reduced, lowering the accident risk.

[0019] 2. After the equipment of the present invention completes one measurement and wire taking operation, it can automatically return to the initial state to prepare for the next operation without manual intervention.

[0020] 3. Through the design of electromagnets and gears, the present invention realizes the stable clamping and stretching of the steel wire ring, and can maintain high operation stability and accuracy even when facing steel wire rings of different materials and shapes.

The inner ring rods 3041 and the outer ring rods 307 on both sides of the measuring upper ring plate 201 are made of conductive metal materials. After the inner ring rods 3041 are electrically connected, the power switch of the inner ring electromagnet 3035 is controlled. After the outer ring rods 307 are electrically connected, the power switch of the outer ring electromagnet 3025 is controlled. When adjacent outer ring rods 307 and inner ring rods 3041 are electrically connected, the power switch of the lifting motor 3051 is controlled to be turned on. A closing switch for the inner ring rod 3041 and the outer ring rod 307 is provided at the measuring machine control panel 101. When the outer ring rods 307 and the outer ring rods 307, the inner ring rods 3041 and the outer ring rods 307, and the inner ring rods 3041 and the inner ring rods 3041 are all in a power-off state, a return operation will be controlled until the inner ring rods 3041 and the outer ring rods 307 are in an open state. Touch pressure switches are installed at both ends of the inner side of the groove of the movable groove 3011. The outer ring electromagnet 3025 is controlled to be powered off at the outer ring rod 307, and the inner ring electromagnet 3035 is controlled to be powered off at the inner ring rod 3041.,

[0036] The working principle of the present invention:

[0037] When in use, first keep the inner ring rod 3041 and the outer ring rod 307 in an open state. At this time, measure the inner circumference of the bead wire. Then, place the tire bead wire at a rough position. At this time, the machine controls the measuring upper ring plate 201 and the measuring lower ring plate 202 to stretch the distance between the stretching distance grooves 2011. The inner circumference of the bead wire is the sum of the semi-circular rings of the measuring upper ring plate 201 and the measuring lower ring plate 202 plus twice the distance of the distance grooves 2011. When measuring, if there is a large difference in the inner circumference diameters of the measuring upper ring plate 201 and the measuring lower ring plate 202 at the position where the bead wire is placed, then start the closing switch of the inner ring rod 3041 and the outer ring rod 307. When the closing switch is turned on, it will cause the outer ring electromagnet 3025 and the inner ring electromagnet 3035 to start, resulting in the generation of magnetic force by the inner ring electromagnet 3035 and the outer ring electromagnet 3025, and thus generating a repulsive force, which makes the inner ring clamping block 3034 snap into the inner ring clamping groove 3031, and the outer ring clamping block 3024 snap into the outer ring clamping groove 3021. At this time, the clamping motor 306 starts to rotate, causing the inner ring large gear 3033 and the outer ring large gear 3023 to rotate, so that the outer ring rod 307 and the inner ring rod 3041 on the same main body shell 301 start to approach each other. When two of the outer ring rods 307 or two of the inner ring rods 3041 first touch the bead wire, a closed circuit is formed, causing the corresponding outer ring electromagnet 3025 or inner ring electromagnet 3035 to lose power, so that the outer ring gear rod 3022 or the inner ring gear rod 3032 is disengaged from the clamped state, and the outer ring threaded rod 302 or the inner ring threaded rod 303 stops rotating. When one of them stops rotating, the other continues to rotate until a closed loop is formed between the outer ring rod 307 and the inner ring rod 3041. At this time, the lifting motor 3051 is powered on, and the winding shaft of the lifting motor 3051 starts to rotate. When the winding shaft rotates, the pulling rope 3075 inside the outer ring rod 307 is pulled. As the pulling rope 3075 is pulled, the lifting block 3072 at the bottom end of the outer ring rod 307 is pulled and moves towards the top end of the outer ring rod 307, thus pulling the bead wire upward until it reaches the maximum pulling range. At this time, the bead wire wire-taking operation is completed. After the bead wire is taken out, at this time in the power-off state, the inner ring electromagnet 3035 and the outer ring electromagnet 3025 push the inner ring clamping block 3034 and the outer ring clamping block 3024 into the corresponding outer ring clamping groove 3021 and inner ring clamping groove 3031. At this time, the clamping motor 306 performs a return operation, pulling back the outer ring rod 307 and the inner ring rod 3041. When the outer ring rod 307 touches the side of the maximum distance at both ends of the movable groove 3011, the pressing switch is triggered, and at this time the outer ring electromagnet 3025 loses power. When the inner ring rod 3041 touches the side of the maximum distance at both ends of the movable groove 3011, the pressing switch is triggered, and at this time the inner ring electromagnet 3035 loses power, thus returning to the initial state. At this time, continue the measurement operation.

Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention.

When the outer ring rod and the outer ring rod, the inner ring rod and the outer ring rod, and the inner ring rod and the inner ring rod are all in a power-off state, a return operation will be controlled until the inner ring rod and the outer ring rod are in an open state. Touch switches are installed at both ends of the inner side of the groove of the movable groove. At the position of the outer ring rod, the power supply of the outer ring electromagnet is cut off. At the position of the inner ring rod, the power supply of the inner ring electromagnet is cut off.

5. A method for automatically detecting a bead ring, implemented in an automatic bead ring detection device according to any one of claims 1-4, characterized in that, It includes the following contents: S1. When in use, first, keep the inner ring rod and the outer ring rod in an open state. At this time, measure the inner circumference of the bead wire. At this time, put the tire bead wire on a rough position. At this time, the machine controls the measuring upper ring plate and the measuring lower ring plate to stretch the distance between the spacing grooves. The inner circumference of the bead wire is the sum of the semi-circular rings of the measuring upper ring plate and the measuring lower ring plate plus twice the spacing of the spacing grooves. When measuring, if the inner circumference diameters of the measuring upper ring plate and the measuring lower ring plate at the position where the bead wire is placed differ greatly, then start the closing switch of the inner ring rod and the outer ring rod. S2. When the closing switch is turned on, the outer ring electromagnet and the inner ring electromagnet will be activated, resulting in the generation of magnetic force and repulsive force by the inner ring electromagnet and the outer ring electromagnet. The inner ring clamping block is clamped into the inner ring clamping groove, and the outer ring clamping block is clamped into the outer ring clamping groove. At this time, the clamping motor starts to rotate, causing the inner ring large gear and the outer ring large gear to rotate, so that the outer ring rod and the inner ring rod on the same main body shell start to approach each other. When two of the outer ring rods or two of the inner ring rods first touch the bead wire, a closed circuit is formed, causing the corresponding outer ring electromagnet or inner ring electromagnet to cut off power, so that the outer ring gear rod or the inner ring gear rod is disengaged from the clamped state, and the outer threaded rod or the inner threaded rod stops rotating. S3. After one of them stops rotating, the other continues to rotate until a closed circuit is formed between the outer ring rod and the inner ring rod. At this time, the lifting motor is energized, causing the winding shaft of the lifting motor to rotate. When the winding shaft rotates, the tension rope inside the outer ring rod is pulled. As the tension rope is pulled, the lifting block at the bottom of the outer ring rod is pulled and moves towards the top of the outer ring rod, thus pulling the wire loop upward until it reaches the maximum pulling range. At this time, the wire loop wire taking operation is completed. After the wire loop is taken out; S4. At this time, in the power-off state, the inner ring electromagnet and the outer ring electromagnet push the inner ring clamping block and the outer ring clamping block into the corresponding outer ring card slot and inner ring card slot. At this time, the clamping motor performs a return operation, pulling back the outer ring rod and the inner ring rod. When the outer ring rod touches the side of the maximum distance between the two ends of the movable slot, the pressing switch is triggered. At this time, the outer ring electromagnet is powered off. When the inner ring rod touches the side of the maximum distance between the two ends of the movable slot, the pressing switch is triggered. At this time, the inner ring electromagnet is powered off, returning to the initial state. At this time, the measurement operation continues.
