Description

Technical Field

[0001] The utility model relates to the technical field of a wire drawing machine structure, in particular to a wire drawing machine for a multi-posture high-precision badminton racket. Background Art

[0002] After the badminton racket is produced, a wire drawing machine is needed to insert and fix the elastic wire used to hit the badminton into the badminton racket and make the elastic wire distributed in a grid. Figure 1~Figure 2 As shown, it includes a base 1, a column fixed on the base 1, and a platform 8 fixed on the top surface of the column. A main shaft 9 is rotatably mounted on the platform 8, a turntable 10 is installed on the top of the main shaft 9, and a racket-holding assembly 19 for holding a badminton racket and a chuck for clamping and fixing an elastic line are arranged on the turntable 10; a screw nut pair 12 located on the left side of the racket-holding assembly 19 is arranged on the top surface of the platform 8, a moving platform 13 is fixed on the nut 21 of the screw nut pair 12, two fixed blocks 26 are fixed on the top surface of the moving platform 13, two guide rods 27 are fixed between the two fixed blocks 26, a slider 28 is slidably installed between the two guide rods 27, a wire clamping assembly 17 is arranged on the top surface of the slider 28, a tension sensor 18 is fixedly connected between the fixed block 26 located on the left and the slider 28, and the tension sensor 18 is connected to the controller.

[0003] The method of threading the elastic wire in a badminton racket using the wire drawing machine is:

[0004] S1. A worker fixes a badminton racket 29 on the racket frame assembly 19, then inserts an elastic line into the badminton racket 29, clamps and fixes the right end of the elastic line with a clamp located on the turntable 10, and then fixes the left end of the elastic line in the clamp assembly 17;

[0005] S2, the driving motor 22 of the control screw nut pair 12 is started, the driving motor 22 drives the screw 23 to rotate, the nut 21 moves linearly to the left along the screw 23, the nut 21 drives the moving platform 13 to move to the left, the moving platform 13 drives the fixed block 26, the guide rod 27, the tension sensor 18, the slider 28 and the wire clamping assembly 17 to move to the left synchronously, the wire clamping assembly 17 pulls the elastic wire to move to the left, so as to straighten the elastic wire;

[0006] S3. When the driving motor 22 moves to the set time, the controller controls the driving motor 22 to turn off, and the nut 21 and the wire clamping assembly 17 no longer move to the left. At this time, the elastic line in the straightened state makes the wire clamping assembly 17 have a tendency to move to the right, and the wire clamping assembly 17 makes the slider 28 have a tendency to move to the right, and the slider 28 makes the tension sensor 18 have a tendency to move to the right. At this time, the tension applied to the tension sensor 18 is the tension value of the elastic line, and the tension sensor 18 transmits the tension value to the controller. The worker can check the current tension value of the elastic line on the controller. If the tension value meets the design requirements of the worker, it is determined that the elastic line is pulled qualified.

[0007] However, although this wire drawing machine can thread the elastic wire in the badminton racket, it still has the following technical defects:

[0008] I. The height of the platform 8 cannot be adjusted, which makes it inconvenient for workers with taller heights to operate; the angle of the platform 8 cannot be adjusted either, which makes it difficult to adapt to workers with different operating skills.

[0009] II. In step S3, there is friction loss between the slider 28 and the guide rod 27, which causes the tension value of the elastic line measured by the tension sensor 18 to be inaccurate, resulting in a technical defect of low precision.

[0010] Therefore, there is an urgent need for a wire drawing machine for a high-precision badminton racket with multiple postures and high precision that can adjust the platform posture. Utility Model Content

[0033] A screw nut pair 12 located on the left side of the turntable 10 is arranged on the top surface of the platform 8, a moving platform 13 is fixedly arranged on the nut 21 of the screw nut pair 12, a connecting seat 14 is fixedly arranged on the top surface of the moving platform 13, a mounting plate 16 is hingedly connected to the connecting seat 14 via a pin 15, a wire clamping assembly 17 is fixedly arranged on the top surface of the mounting plate 16, and a tension sensor 18 tilted upward to the right is fixedly arranged between the mounting plate 16 and the moving platform 13.

[0034] The screw-nut pair 12 includes a nut 21, a drive motor 22 fixed on the platform 8, and a die set frame, a screw rod 23 arranged horizontally is rotatably mounted on the die set frame, an output shaft of the drive motor 22 is connected to the right end of the screw rod 23, and the nut 21 is threadedly connected to the screw rod 23. The screw-nut pair 12 also includes a guide rail 24 fixed on the platform 8 and parallel to the screw rod 23, a sliding block 25 is slidably mounted on the guide rail 24, and the rear end of the moving platform 13 is fixed on the top surface of the sliding block 25.

[0035] The wire drawing machine also includes a controller, which is electrically connected to the lifting electric cylinder 2, the angle adjustment electric cylinder 11, the tension sensor 18 and the drive motor 22 via a signal line. The controller can control the extension or retraction of the piston rods of the lifting electric cylinder 2 and the angle adjustment electric cylinder 11, and can also control the start or shutdown of the drive motor 22, which facilitates the operation of the workers.

[0036] The working process of the utility model is as follows:

[0037] S1. A worker fixes a badminton racket 29 on the racket frame assembly 19, then inserts an elastic line into the badminton racket 29, clamps and fixes the right end of the elastic line with a clamp located on the turntable 10, and then fixes the left end of the elastic line in the clamp assembly 17;

[0038] S2, the driving motor 22 of the control screw nut pair 12 is started, the driving motor 22 drives the screw 23 to rotate, the nut 21 moves linearly to the left along the screw 23, the nut 21 drives the moving platform 13 to move to the left, the moving platform 13 drives the connecting seat 14, the mounting plate 16, the tension sensor 18 and the clamping assembly 17 to move to the left synchronously, the clamping assembly 17 pulls the elastic wire to move to the left, so as to straighten the elastic wire;

[0039] S3. When the driving motor 22 moves to the set time, the controller controls the driving motor 22 to turn off, and the nut 21 and the wire clamping assembly 17 no longer move to the left. At this time, the elastic line in the straightened state makes the wire clamping assembly 17 have a tendency to rotate right around the pin shaft 15, and the wire clamping assembly 17 makes the mounting plate 16 have a tendency to rotate right around the pin shaft 15, and the mounting plate 16 makes the tension sensor 18 have a tendency to rotate right. At this time, the tension applied to the tension sensor 18 is the tension value of the elastic line, and the tension sensor 18 transmits the tension value to the controller. The worker can check the current tension value of the elastic line on the controller. If the tension value meets the design requirements of the worker, the elastic line is judged to be pulled qualified.

[0040] It can be seen from step S3 that since the tension applied by the elastic line to the clamping assembly 17 is directly transmitted to the tension sensor 18, compared with Figure 1~Figure 2 The wire drawing machine shown has no friction loss in the middle, thereby ensuring that the tension of the elastic wire measured by the tension sensor 18 is accurate. Therefore, the wire drawing machine has the characteristic of higher accuracy.

[0041] S4. When a tall worker wants to use the wire drawing machine, the worker can control the piston rod of the lifting cylinder 2 to extend upward, and the piston rod drives the lifting plate 3 to move upward. The lifting plate 3 drives the hinge seat 5 and the support plate 4 to move upward synchronously, thereby driving the platform 8 to move upward, so that the wire drawing machine is suitable for tall workers to operate without the need for the worker to bend over to operate.

[0042] The piston rod of the angle-adjusting electric cylinder 11 can also be controlled to extend upward, and the piston rod causes the platform 8 and the rotating block 7 to rotate synchronously relative to the pin 15, thereby changing the angle of the platform 8 to make the wire drawing machine adaptable to workers with different operating techniques.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
