Description

Technical Field

[0001] The utility model relates to the technical field of I-shaped wheel detection, in particular to an I-shaped wheel inner hole automatic detection device. Background Art

[0002] The I-spool plays an important role in the production of steel cord. It is mainly used for winding and fixing steel wire. It ensures the orderly storage, fixation and tension adjustment of the steel wire, thereby ensuring the quality and production efficiency of the steel cord. After the I-spool is used, due to the high winding strength, high speed of the I-spool top shaft or collision during transportation, the inner hole of the I-spool may be deformed or damaged. When reused, some I-spools that are not tested cannot be installed on the top shaft of the equipment, and some have poor dynamic balance, causing winding failures. More seriously, the equipment will be damaged, posing quality risks.

[0003] Therefore, the I-spools must be inspected before they are reused. The original inspection method was manual inspection, that is, workers held a through gauge that matched the inner hole and passed it through each I-spool inner hole. If it failed to pass, it was considered unqualified and needed to be reshaped. The efficiency of manual inspection was relatively low, and manual inspection was arbitrary. It could not guarantee that the through gauge would completely penetrate the inner hole of each I-spool during the inspection process, so there was still a risk of unqualified products.

[0026] In order to better understand the technical content of the present invention, specific embodiments are described below in conjunction with the accompanying drawings.

[0027] like Figure 1 and Figure 2 As shown, the utility model provides an automatic detection device for the inner hole of an I-shaped wheel, which aims to improve the speed and accuracy of the detection of the inner hole of the I-shaped wheel to ensure that the I-shaped wheels after detection can meet the qualified use standards. The device mainly includes a workbench 10, a driver 20, a positioner and a sensor 50.

[0028] Among them, a support rod 11 made of a square tube is arranged below the workbench 10 for installing the workbench 10. The upper part of the workbench 10 has a horizontally arranged bearing surface for placing the I-shaped wheel 100, and a through hole 101 with the same diameter as the wheel hole 001 is opened on the bearing surface. The driver 20 is arranged below the workbench 10, and can drive the through gauge 30 to pass through the through hole 101 in a direction perpendicular to the bearing surface.

[0029] Furthermore, the outer diameter of the through gauge 30 is equal to the inner diameter of the wheel hole 001, and the length of the through gauge 30 is greater than or equal to the length of the wheel hole 001, so that the through gauge 30 can fit the inner wall of the wheel hole 001. When deformation occurs inside the wheel hole 001, the through gauge 30 can detect it and push the I-shaped wheel 100 upward, making it convenient for manual judgment that the I-shaped wheel 100 is a defective product.

[0030] Furthermore, the driver 20 can adopt an electric telescopic rod or a pneumatic telescopic rod, and the working stroke of the driver 20 is greater than or equal to the length of the wheel hole 001, so that the through gauge 30 can completely pass through the wheel hole 001 to determine whether there is a deformed part in the wheel hole 001.

[0031] In a specific embodiment, a staff member places the I-shaped wheel 100 on the bearing surface of the workbench 10, and aligns the wheel hole 001 of the I-shaped wheel 100 with the through hole 101 on the bearing surface, and uses the driver 20 below to drive the through gauge 30 to move upward, and inserts the through gauge 30 into the wheel hole 001 to detect whether the wheel hole 001 is regular and whether the wheel hole 001 is deformed or damaged. When the wheel hole 001 is deformed or damaged, it will hinder the movement of the through gauge 30, and the I-shaped wheel 100 will be driven by the through gauge 30 to move upward, and the I-shaped wheel 100 will be judged as a defective product. If the through gauge 30 can pass through the wheel hole 001 smoothly, the I-shaped wheel 100 is a qualified product.

[0032] When the spool 100 is placed on the bearing surface, a positioner is provided on the bearing surface to facilitate rapid alignment of the wheel hole 001 and the through hole 101 , and the positioner is used to position the spool 100 to a set position.

[0033] Furthermore, the positioner includes at least two positioning blocks 40, and the distribution positions of the positioning blocks 40 are set as follows: when the edge of the I-shaped wheel 100 contacts at least two positioning blocks 40 at the same time, the wheel hole 001 coincides with the through hole 101, wherein the positioning blocks 40 use the known radius of the I-shaped wheel 100 and the two determined points on the circumference of the I-shaped wheel 100 to determine the center position of the I-shaped wheel 100.

[0034] In this way, the staff puts the I-shaped wheel 100 on the bearing surface and pushes it in the direction of the positioning block 40 until the edge of the I-shaped wheel 100 contacts the two positioning blocks 40 at the same time. The center position of the I-shaped wheel 100 can reach the set position, that is, the wheel hole 001 of the I-shaped wheel 100 coincides with the through hole 101.

[0035] In order to ensure that when the I-shaped wheel 100 reaches the set position, the driver 20 can start working and drive the through gauge 30 to pass upward into the through hole 101 for detection, a sensor 50 is also arranged on the bearing surface. The sensor 50 is used to detect whether the I-shaped wheel 100 reaches the set position. A protective shell 12 is also arranged on the upper side of the protective shell to prevent the sensor 50 from being damaged by the I-shaped wheel 100 from colliding from the top.

[0036] In some embodiments, the contact point between the positioning block 40 and the edge of the spool 100 is defined as a limit point, and the contact point between the sensor 50 and the edge of the spool 100 is defined as a sensing point. The sensing point and the limit point are distributed on a circle where the edge of the spool 100 is located. In this way, when the edge of the spool 100 contacts the two positioning blocks 40 at the same time, it will also contact the sensor 50, so that the sensor 50 detects that the spool 100 has reached the set position.

[0037] like Figure 3As shown, in a preferred embodiment, the positioner includes two positioning blocks 40 symmetrically distributed on both sides of the line connecting the center of the through hole 101 and the sensing point, and the length of the line between the two limit points is less than the length of the diameter of the I-wheel 100. In this way, the staff only needs to roughly push the I-wheel 100 toward the sensor 50. After the I-wheel 100 contacts one of the positioning blocks 40, it will move closer to the other positioning block 40 until the I-wheel 100 contacts the two positioning blocks 40 at the same time and reaches the set position, which makes it more convenient for the staff to push the I-wheel 100 to the preset position.

[0038] Optionally, the angle between the two limiting points and the line connecting the center of the circle where the through hole 101 is located is set at 60°-120°, and the positioning blocks 40 distributed within this angle range can more easily position the I-shaped wheel 100.

[0039] Furthermore, the driver 20 is configured as follows: when the sensor 50 detects that the I-shaped wheel 100 has reached the set position, the through gauge 30 is driven to pass upward into the through hole 101. It should be understood that the sensor 50 and the driver 20 are connected to the same control circuit. When the sensor 50 detects that the I-shaped wheel 100 has reached the set position, the detection signal is transmitted to the control circuit, and the control circuit controls the driver 20 to turn on, thereby realizing the inductive linkage relationship between the sensor 50 and the driver 20.

[0040] In some embodiments, the sensor 50 may be a capacitive trigger sensor, a resistive touch sensor, or a contact pressure sensor, all of which have the characteristics of fast response and high accuracy.

[0041] Since the rim of the I-shaped wheel 100 may be lifted or deformed due to collision, when the rim of the I-shaped wheel 100 is in place with the positioning block 40, the deformed part is at the sensor 50, so that the sensor 50 cannot timely recognize that the I-shaped wheel 100 is in place. Therefore, in order to avoid the above situation, the sensor 50 optionally includes at least one contact sensor distributed between any two adjacent positioning blocks 40, that is, at least three positioning blocks 40 are provided, and two sensors 50 are provided. By detecting the rim of the I-shaped wheel 100 at multiple points, the detection accuracy can be improved.

[0042] In combination with the above embodiments, a positioning block 40 for positioning the I-shaped wheel 100 and a sensor 50 for detecting whether the I-shaped wheel 100 is in place are arranged on the workbench 10, and the driver 20 can drive the through gauge 30 to detect the I-shaped wheel 100 after it is in place, thereby solving the problem of low efficiency of manual inspection. The driver 20 can move in place every time, eliminating the arbitrariness of manual work, effectively improving the accuracy of inner hole inspection of the I-shaped wheel 100, and reducing the risk of defective products flowing into the production process. In addition, the device has a compact structure, occupies a small area, and is easy to take the I-shaped wheel 100.

[0043] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. A person with ordinary knowledge in the technical field to which the present invention belongs may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the definition of the claims.
