[0002] This invention relates to a method for testing the winding tension, belonging to the field of magnetic winding auxiliary technology. Background Technology

[0003] When winding wire, the tension of the inclined rubber wheel on the winding machine must be specific. Most existing technologies test the straight line of the winding held by the inclined rubber wheel. However, the winding held by the inclined rubber wheel is usually wound on the storage ring. The straight line test will have some error. There is currently no specific tension testing instrument to accurately test the tension of the winding on the storage ring. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a winding tension testing device that can accurately measure the winding tension on the wire storage ring.

[0005] Another objective of this invention is to provide a method for testing the tensile strength of a winding.

[0006] This invention is achieved through the following technical solution:

[0007] A winding tensile testing device is characterized by comprising an adjustable mounting base and a force gauge mounted on the base, wherein a simulated force-bearing component is connected to the force gauge.

[0008] The winding tension testing device described above is characterized in that the simulated force-bearing component and the force gauge are connected by a connector.

[0009] The winding tension testing device described above is characterized in that the simulated force component includes a connecting arm and a tension block connected to the force gauge.

[0010] The winding tensile testing device described above is characterized in that the tensile block simulates a portion of the peripheral wall of a magnetic ring, the force direction of the tensile block is inclined to the direction of the force measured by the force gauge, and the resultant force direction of the tensile block is consistent with the direction of the force measured by the force gauge.

[0011] The winding tensile testing device described above is characterized in that the base is adjustablely fixed to the relative position of the winding to be tested via a connecting block.

[0012] The winding tensile testing device described above is characterized in that the base is provided with a limiting member to prevent the force gauge from shifting.

[0015] a. Connect a simulated force-bearing component to the force-bearing end of the force gauge;

[0016] b. Fix the force gauge so that the direction of the tensile force on the simulated force-bearing component is consistent with the direction of the force on the actual force-bearing component;

[0017] c. By winding the wire onto the simulated stress-bearing component as in actual operation, the tensile force on the simulated stress-bearing component can be tested.

[0018] The simulated force-bearing component includes a connecting arm aligned with the force direction of the force gauge, and a tension block is connected to the free end of the connecting arm.

[0022] Figure 1 This is one of the three-dimensional structural schematic diagrams of the present invention;

[0023] Figure 2 This is a schematic diagram of the exploded structure of the present invention;

[0024] Figure 3 This is the second schematic diagram of the three-dimensional structure of the present invention. Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings:

[0026] like Figure 1-3 As shown, a winding tensile testing device includes an adjustable base 1 and a force gauge 2 mounted on the base 1. A simulated force-bearing component 3 is connected to the force gauge 2. The simulated force-bearing component 3 is connected to the force gauge 2 via a connector 4.

[0027] The simulated force-bearing component 3 includes a connecting arm 31 connecting to the force gauge 2 and a tension block 32. In the magnetic ring winding tension test, the tension block 32 simulates part of the magnetic ring's peripheral wall and is inclined axially to the connecting arm 31. The connecting arm 31 is a U-shaped arm, forming a hollow frame with the tension block 32, allowing the winding wire to pass through and wind around the tension block 32. The resultant force direction of the tension block 32 is consistent with the force direction of the force gauge 2.

[0028] Preferably, the tension block 32 and the connecting arm 31 are tenoned and snapped together, which makes it easy to replace different tension blocks 32 for different magnetic rings, making the invention more widely applicable. It also facilitates replacement of damaged parts without replacing the whole machine and increasing testing costs.

[0029] Preferably, the base 1 is adjustablely fixed relative to the winding to be tested by the connecting block 5. The connecting block 5 includes a mounting block 51 connected to the base 1, and a screw 53 and bolt 52 fixed to the machine tool. The mounting position of the base 1 can be adjusted by tightening or loosening the bolt 52, thereby adjusting the position of the simulated force-bearing member 3 relative to the winding.

[0030] Preferably, the base 1 is provided with limiting members 11 to prevent the force gauge 2 from shifting. The limiting members 11 are divided into three parts, which restrict the displacement of the force gauge 2 from three directions. The simulated force-bearing member 3 passes through the limiting members 11 and connects to the force gauge 2. The installation position of the force gauge 2 on the base 1 is adjustable, and its adjustment direction intersects with the installation adjustment direction of the base 1. Further, the base 1 is provided with two slotted holes 12, and the force gauge 2 can be adjusted away from or towards the base 1 in its unrestricted direction, that is, the simulated force-bearing member 3 can move forward or backward, thereby realizing fine adjustment of the position of the simulated force-bearing member 3.

[0031] This invention is preferably applicable to disc winding machines. The simulated force-bearing component 3 is placed on the wire storage ring at the position where the magnetic ring is inserted to simulate magnetic winding and test the winding tension.

[0032] This invention discloses a method for testing the tensile strength of a winding, characterized by comprising the following steps:

[0033] a. Connect a simulated force-bearing component to the force-bearing end of the force gauge;

[0034] b. Fix the force gauge so that the direction of the tensile force on the simulated force-bearing component is consistent with the direction of the force on the actual force-bearing component;

[0035] c. By winding the wire onto the simulated stress-bearing component as in actual operation, the tensile force on the simulated stress-bearing component can be tested.

[0036] In the testing method, the simulated force-bearing component 3 includes a connecting arm 31 aligned with the force direction of the force gauge 2, and a tension block 32 is connected to the free end of the connecting arm 31. When testing the tension of the winding on the magnetic ring, the tension block 32 simulates part of the peripheral wall of the magnetic ring. The force direction of the tension block 32 is inclined to the direction tested by the force gauge 2, and the resultant force direction of the tension block 32 is aligned with the direction tested by the force gauge 2.

[0037] When testing the winding tension of the magnetic ring on the storage ring of the disc magnetic winding machine, the force gauge 2 is installed on the base 1, and the base 1 is then installed on the working plate of the disc magnetic winding machine where the storage ring is placed. The bolt 52 is adjusted to adjust the relative position of the base 1 and the winding, and the installation position of the force gauge 2 is adjusted to adjust the position of the tension block 32 so that it is in the position when the magnetic ring is wound on the storage ring. Then the winding begins on the tension block 32, and the winding tension is tested. If the tension is appropriate, the testing device is removed, and winding can begin. If the tension is inappropriate, the tension of the winding is adjusted, and the tension is tested again until it is appropriate.
