Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire ring clamping technology, and in particular to a wire ring clamping and measuring structure. Background Technology
[0002] In tire manufacturing, the bead wire, a key component supporting the tire structure, directly affects the dimensional accuracy of its inner circumference and radius, impacting subsequent production and final product quality. Traditionally, bead wire measurement relies heavily on manual measurement, with sampling and retesting during production. This method is not only time-consuming and labor-intensive, but the sampling frequency directly impacts production efficiency and product quality: too high a sampling frequency reduces efficiency, while too low a frequency makes it difficult to guarantee product quality. Utility Model Content
[0003] The purpose of this invention is to provide a wire coil clamping and measuring structure that integrates a clamping device and a measuring device, enabling rapid clamping and accurate measurement of the wire coil, thereby improving production efficiency.
[0004] To achieve the above objectives, this utility model provides a wire coil clamping and measuring structure, including a clamping device and a measuring device; the clamping device includes a chuck, the front of which has multiple radially sliding jaws for clamping the wire coil and a driving structure for driving the jaws to slide accordingly; the driving structure is equipped with a force sensor for monitoring the clamping force; the measuring device includes a linear displacement sensor mounted on the chuck, which is used to detect the displacement of the jaws.
[0005] With the above structure, the steel wire ring is quickly clamped by the clamping device, and the clamping force is ensured by the force sensor, thereby avoiding damage to the steel wire ring and preventing inaccurate measurement due to insufficient clamping force. Then, the displacement of the jaws is measured by the linear displacement sensor, and the actual radius of the steel wire ring is calculated, thereby achieving accurate measurement and improving production efficiency.
[0006] Preferably, the measuring device also includes an alarm device, which is connected to the linear displacement sensor. When the measured size of the wire coil exceeds the preset range, the alarm device will issue a warning to remind the operator to take action.
[0007] Preferably, the linear displacement sensor is a pull rod displacement sensor, with its base fixed to the chuck and the pull rod fixed to the gripper; the extension and retraction direction of the pull rod is consistent with the sliding direction of the gripper. This design allows for precise measurement of the gripper's displacement, thereby calculating the diameter of the wire coil and achieving accurate measurement.
[0008] Preferably, the displacement sensor is fixed to the chuck by a bracket. The bracket has an oblong hole aligned with the sliding direction of the gripper, and the chuck has a threaded hole corresponding to the oblong hole. The threaded hole and the oblong hole are locked together by bolts. This design facilitates the installation and adjustment of the linear displacement sensor.
[0009] Preferably, the outer side of the pull rod is equipped with a dustproof tube. The dustproof tube is an elastic tube, with one end fixed to the outside of the cylinder base and the other end fixed to the gripper. The dustproof tube reduces the influence of dust and debris on the linear displacement sensor. At the same time, the dustproof tube is an elastic tube structure, which will not affect the extension and retraction of the pull rod, thus not affecting the measurement accuracy.
[0010] Preferably, the chuck is provided with multiple guide grooves; the guide grooves extend radially outward from the center of the chuck, and a slider is slidably installed in each guide groove, with the grippers fixed on the slider. This structure ensures the stability of the gripper operation and guarantees the position of the grippers.
[0011] Preferably, a turntable is rotatably mounted at the center of the chuck, and a drive structure drives the turntable to rotate; the slider is evenly hinged to the turntable via connecting rods. This structure allows multiple grippers to operate simultaneously, achieving rapid clamping.
[0012] Preferably, the drive structure is a stepper motor, and the output shaft of the stepper motor is connected to the central shaft of the turntable. By controlling the rotation angle and speed of the stepper motor, the movement of the gripper can be precisely controlled.
[0013] Preferably, the driving structure is a telescopic mechanism, and the output shaft of the telescopic mechanism is fixed on any of the sliders. By controlling the sliding of any one of the sliders through the telescopic mechanism, the rotation of the turntable is achieved, thereby controlling the sliding of the other sliders.
[0014] Preferably, the grippers are arc-shaped plate structures, which are supported on the inner wall of the wire ring by an internal expansion clamping method. This internal expansion structure prevents deformation of the wire ring.
[0015] After adopting the above technical solution, the beneficial effects of this utility model are:
[0016] This utility model provides a wire ring clamping and measuring structure that solves the technical problems of low sampling efficiency and inaccurate measurement in the wire ring production process of the prior art. This utility model integrates a clamping device and a measuring device, which can realize the rapid clamping and accurate measurement of the wire ring, thereby improving production efficiency. Attached Figure Description
[0017] Figure 1 This is a schematic diagram of a wire ring clamping and measuring structure according to the present invention;
[0018] Figure 2 yes Figure 1 The front view;
[0019] Figure 3 yes Figure 1 Rear view.
[0020] In the figure, 1 is the clamping device, 11 is the chuck, 111 is the guide groove, 12 is the gripper, 13 is the turntable, 14 is the connecting rod, 15 is the slider, 2 is the measuring device, 21 is the linear displacement sensor, 22 is the bracket, and 23 is the dustproof tube. Detailed Implementation
[0021] The present invention will be further described below with reference to the accompanying drawings.
[0022] The orientations mentioned in this specification are based on the orientation of the wire ring clamping and measuring structure of this utility model when it is working normally. They do not limit the orientation during storage and transportation, and only represent relative positional relationships, not absolute positional relationships.
[0023] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, a wire coil clamping and measuring structure includes a clamping device 1 and a measuring device 2.
[0024] The clamping device 1 includes a chuck 11. The front of the chuck 11 has multiple radially slidable jaws 12 for clamping the wire coil, and a driving structure for driving the jaws 12 to slide accordingly. In this embodiment, four jaws 12 are provided, but in actual applications, three or five can be provided. The chuck 11 is provided with multiple guide grooves 111, which extend radially outward from the center of the chuck 11. A slider 15 is slidably installed in each guide groove 111, and the jaws 12 are fixed to the slider 15. The multiple jaws 12 are evenly arranged around the chuck 11 and form a circular structure. Thus, when the driving structure drives the slider 15 to slide within the guide groove 111, the jaws 12 can move radially towards or away from the center of the chuck 11, ensuring the positional accuracy and precision of the jaws 12.
[0025] The gripper 12 is preferably an arc-shaped plate structure, which is supported on the inner wall of the wire ring by an inward expansion clamping method. This structure can better adapt to the shape of the wire ring, improve the accuracy of clamping and measurement, and avoid damage to the wire ring. At the same time, the drive structure is equipped with a force sensor to monitor the clamping force; ensuring that the wire ring is firmly clamped and will not be damaged due to excessive clamping force.
[0026] The measuring device 2 includes a linear displacement sensor 21 mounted on the chuck 11, which is used to detect the displacement of the gripper 12. By measuring the displacement of the gripper 12, the size of the wire coil can be indirectly calculated, thus achieving accurate measurement.
[0027] Specifically, the measuring device 2 may also include an alarm device, which is connected to the linear displacement sensor 21. When the measured size of the wire coil exceeds the preset range, the alarm device will issue a warning to remind the operator to take action.
[0028] The linear displacement sensor 21 can be a photoelectric displacement sensor, an electromagnetic displacement sensor, etc. In this embodiment, it is preferably a pull rod displacement sensor, with its base fixed on the chuck 11 and the pull rod fixed on the gripper 12. The extension and retraction direction of the pull rod is consistent with the sliding direction of the gripper 12, ensuring that the sensor can accurately detect the displacement of the gripper 12.
[0029] To facilitate the installation and adjustment of the linear displacement sensor 21, the sensor is fixed to the chuck 11 via a bracket 22. The bracket 22 has an oblong hole aligned with the sliding direction of the gripper 12, and the chuck 11 has a corresponding threaded hole. The bracket 22 is secured to the chuck 11 by tightening bolts. This design not only facilitates sensor installation and adjustment but also improves measurement accuracy.
[0030] To prevent dust and debris from affecting the linear displacement sensor 21, this invention also includes a dustproof tube 23 covering the outside of the pull rod. The dustproof tube 23 is an elastic tube, preferably a corrugated tube in this embodiment, with one end fixed to the outside of the cylinder base and the other end fixed to the gripper 12. When the gripper 12 moves, the dustproof tube 23 can extend and retract accordingly, effectively preventing dust and debris from entering the sensor. Furthermore, the dustproof tube 23 is an elastic tube structure, which does not affect the extension and retraction of the pull rod, thus not affecting the measurement accuracy.
[0031] Furthermore, a turntable 13 is rotatably mounted at the center of the chuck 11, and a drive structure drives the turntable 13 to rotate. Sliders 15 are evenly hinged to the turntable 13 via connecting rods 14. When the turntable 13 rotates, the connecting rods 14 drive the sliders 15 to slide within the guide grooves 111, thereby achieving synchronous movement of the grippers 12. This design is not only compact but also enables synchronous gripping of the grippers 12 and allows for precise displacement of each gripper 12.
[0032] The driving structure can be a stepper motor or a telescopic mechanism. In one embodiment, the driving structure is a stepper motor, with its output shaft connected to the central shaft of the turntable 13. By controlling the rotation angle and speed of the stepper motor, the movement of the gripper 12 can be precisely controlled. In another embodiment, the driving structure is a telescopic mechanism, with its output shaft fixed to any slider 15. Through the telescopic movement of the mechanism, the slider 15 can slide within the guide groove 111, thereby rotating the turntable 13 and causing other sliders 15 to slide within the guide groove 111, thus realizing the movement of the gripper 12. Both driving methods can achieve precise control of the gripper 12, improving measurement accuracy.
[0033] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
