Description

Technical Field

[0001] The utility model relates to the technical field of wire diameter measurement, in particular to a device for measuring the diameter of special-shaped wires. Background Art

[0002] As the size requirements for pipe and wire products become increasingly higher, diameter gauges, as a non-contact, real-time outer diameter detection device, are increasingly being used in the production of pipe and wire products. They can be used for product quality monitoring, data analysis, and feedback control of the production process, playing a very important role in improving product quality and reducing costs.

[0003] Laser diameter gauge is an instrument that uses laser to measure the diameter of workpieces or materials. It is now widely used in industrial production. Laser diameter gauge can be used to measure the diameter information of various rolled materials online. It can measure the maximum diameter, minimum diameter, average diameter, and other information online.

[0004] In the prior art, there is a Chinese patent with application number 202220089230.X, authorization announcement number CN216815358U, and name "A wire outer diameter measuring fixture". The above patent discloses a wire outer diameter measuring fixture, including a base, a detection device and a fixing device. The detection device and the fixing device are both arranged on the base. The detection device includes a laser diameter gauge and a track. The laser diameter gauge moves along the track direction, and the detection device is used to detect the outer diameter of the wire; the fixing device is used to fix the wire so that the wire remains parallel to the moving direction of the laser diameter gauge and allows the wire to pass through the detection port of the laser diameter gauge.

[0005] The aforementioned patent solves the problem of severe manual diameter measurement errors by combining a detection device with a fixing device. However, it is well known that during the production and processing of wires, a large amount of dust and impurities may remain on the surface of the wire. In existing technologies, such as the aforementioned patent, the wire dimensions are directly measured using a laser diameter gauge. However, impurities retained on the wire surface can cause large errors in the wire diameter measurement process, affecting the accuracy of the wire diameter measurement. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-7 The utility model provides a technical solution: a device for measuring the diameter of a special-shaped wire, comprising a device body 1, a wire body 2 passing through the interior of the device body 1, and a cleaning member for cleaning the wire body 2 is provided on one side of the device body 1; the cleaning member comprises two mounting frames 8 connected to both sides of the device body 1 for sliding toward each other, each mounting frame 8 is provided with a cleaning plate 15, and a driving unit for driving the two mounting frames 8 to slide toward each other is provided on the device body 1; and a diameter measuring mechanism is provided on the side of the device body 1 away from the cleaning member.

[0029] Specifically, the device for measuring the diameter of a special-shaped wire includes a device body 1, and a wire body 2 is passed through the inside of the device body 1. As is known, the wire body 2 is in motion. A cleaning member for cleaning the wire body 2 is provided on one side of the device body 1. When the cleaning member abuts against the wire body 2, the cleaning member will clean the wire body 2 as the wire moves. The cleaning member includes two mounting frames 8 that are connected to the two sides of the device body 1 for sliding toward each other. A cleaning plate 15 is provided inside each mounting frame 8, and a driving unit for driving the two mounting frames 8 to slide toward each other is provided on the device body 1. A diameter measuring mechanism is provided on the side of the device body 1 away from the cleaning member, which facilitates the diameter measuring operation of the cleaned wire body 2 through the diameter measuring mechanism. Therefore, during use, after the two mounting frames 8 are driven by the driving unit to slide toward each other to a predetermined position, the cleaning plate 15 will abut against the wire body 2. The distance of the cleaning plate 15 can be adjusted according to different wires, thereby further improving the practicality of the entire diameter measuring device. Afterwards, the cleaning plate 15 cleans the wire body 2 in operation, thereby removing impurities and foreign matter on the surface of the wire, thereby improving the accuracy of subsequent diameter measuring mechanisms during measurement operations, reducing measurement errors, and meeting work needs.

[0030] Specifically, a mold with concave and convex measuring blocks that fit the shaped wire is typically prefabricated. When measuring the diameter, simply matching the concave and convex blocks together yields the top and bottom thickness of the shaped wire. The left and right width of the shaped wire is typically measured by placing auxiliary blocks on either side of the wire in close contact.

[0031] In the embodiment provided by the present invention, a mounting groove 10 is provided on the mounting frame 8, and the cleaning plate 15 is installed in the mounting groove 10 through the connecting frame 12 and the mounting block 11, thereby improving the stability of the cleaning plate 15 during installation.

[0032] In another embodiment provided by the present invention, the connecting frame 12 is slidably connected to the mounting block 11, and a spring is provided between the mounting block 11 and the connecting frame 12. The elastic force of the spring drives the cleaning plate 15 to contact the wire body 2. At this time, when the cleaning plate 15 is worn, the spring has an automatic compensation effect, thereby improving the cleaning efficiency and greatly enhancing the practicality of the diameter measuring device.

[0033] In the embodiment provided by the present invention, a fastener is provided between the mounting block 11 and the device body 1. When the cleaning plate 15 abuts against the wire body 2, the fastener secures the mounting block 11 within the mounting groove 10, thereby improving the stability of the cleaning plate 15 during installation. When the cleaning plate 15 is worn to the point of being unusable, the fastener unlocks the cleaning plate 15, facilitating replacement of the cleaning plate 15.

[0034] In the embodiment provided by the present invention, the fastener comprises a trigger lever 13 fixedly connected to the connecting frame 12. The device body 1 is provided with an inclined guide slot 14, within which the trigger lever 13 slides. Therefore, after the trigger lever 13 slides into the guide slot 14, it drives the connecting frame 12 and the mounting block 11 into contact with the mounting slot 10, securing the cleaning plate 15. Once the trigger lever 13 slides out of the guide slot 14, it no longer exerts a horizontal force on the mounting block 11, allowing easy removal of the mounting block 11 from the mounting slot 10, greatly facilitating replacement of the cleaning plate 15.

[0035] In the embodiment provided by the present invention, the driving unit includes a bidirectional screw 17 rotatably connected to the device body 1, and a driving block 9 is provided on the bottom of each mounting frame 8. The two driving blocks 9 are respectively threadedly connected to the two ends of the bidirectional screw 17; the device body 1 is also provided with a driving part for driving the bidirectional screw 17 to rotate. Therefore, when in use, the bidirectional screw 17 is driven to rotate by the driving part, and the two driving blocks 9 are driven to slide by the mounting block 11, so that the cleaning plate 15 can be slid to a predetermined state through the mounting frame 8, which improves the use effect.

[0036] In the embodiment provided by the present invention, the driving part is a handle, which is threadedly connected to the bidirectional screw rod 17, thereby saving costs. At the same time, the bidirectional screw rod 17 has a self-locking function, which can fix the state of the cleaning plate 15.

[0037] In another embodiment provided by the present invention, the driving part is a servo motor, and the servo motor is coaxially connected to the bidirectional screw rod 17 through a reducer to improve work efficiency.

[0038] In the embodiment provided by the present invention, a cleaning block 16 is further provided inside the cleaning plate 15 , and the cleaning block 16 is adapted to the wire body 2 , thereby further improving the cleaning efficiency of the wire body 2 .

[0039] In the embodiment provided by the present invention, the diameter measuring mechanism includes a supporting frame 4 arranged inside the device body 1, and connecting rods 5 are slidably connected on both sides of the supporting frame 4. Auxiliary blocks 3 are provided on each connecting rod 5, and the two auxiliary blocks 3 are respectively abutted against the two sides of the wire body 2, and a grating sensor component 7 is provided between the two connecting rods 5, and a tension spring 6 is provided between the two connecting rods 5. Specifically, the grating sensor component 7 refers to a sensor that uses the principle of grating fringe strips to measure displacement. The grating is a dense and evenly spaced parallel grid line on a long strip of optical glass, and the grid line density is 10 to 100 lines / mm. The grid stripes formed by the grating have an optical magnification effect and an error averaging effect, thereby improving the measurement accuracy. By measuring the distance between the two connecting rods 5 through the grating sensor component 7, the wire body 2 can be measured.

[0040] It should be noted that the electrical equipment involved in this application can be powered by batteries or external power supply.
