[0002] In the field of automobile maintenance and spare part replacement, removing the air curtain buckle of an automobile is a common and important operation. Traditionally, maintenance personnel mainly rely on ordinary circlip pliers to complete this task. However, ordinary circlip pliers are not optimized for the removal of automobile air curtain buckles in terms of design, so there are many inconveniences and limitations in the actual operation process.

[0003] Firstly, the shape and structure of ordinary circlip pliers do not match the shape of the automobile air curtain buckle, resulting in more time and effort required for adjustment and adaptation when removing the buckle. This not only reduces work efficiency but also may cause damage to the buckle or automobile parts due to improper operation. Secondly, due to the lack of a professional bending design, it is difficult for ordinary circlip pliers to meet the precise requirements in terms of force application and angle control, and it is difficult to meet the strict standards of precision and reliability in automobile maintenance. In addition, the inconvenience of traditional circlip pliers when removing the air curtain buckle may also increase the work intensity of maintenance personnel, and long-term use is likely to cause occupational fatigue and operation errors.

[0044] The following details the embodiments of the present invention. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0045] Please refer to Figures 1 to 5 , in the first aspect, the present invention provides a method for bending the tip of an air intake curtain buckle pliers for an automobile, including the following steps:

[0046] S1 Fix a common circlip pliers on the bending tool;

[0047] S11 Place the circlip pliers in the fixture mechanism of the fixing device so that the pliers body of the circlip pliers is in close contact with the inner wall of the fixture mechanism;

[0048] Specifically, the fixing device of the bending tooling adopts a mechanical fixture mechanism. The inner wall of the fixture mechanism is designed with a groove that matches the outer shape of the circlip pliers, ensuring uniform force during the clamping process of the circlip pliers and preventing sliding. The clamping bolt is made of high-strength alloy steel, which can provide sufficient clamping force and has good wear resistance and fatigue resistance. Align the body of the circlip pliers with the groove of the fixture mechanism and place it in, so that the body of the circlip pliers fits closely with the inner wall of the fixture mechanism.

[0049] S12 Tighten the clamping bolt to make the fixture mechanism apply a clamping force to the circlip pliers, ensuring that the circlip pliers will not displace during the bending process;

[0050] Specifically, use a wrench to tighten the clamping bolt and apply a clamping force according to the preset torque value to ensure that the circlip pliers will not displace during the bending process.

[0051] S13 Use the positioning block to finely adjust the position of the circlip pliers so that its front end is at the center of the working area of the bending tooling.

[0052] Specifically, use the positioning block to finely adjust the position of the circlip pliers. The positioning block can accurately adjust the position of the circlip pliers in three-dimensional space through a precise thread adjustment mechanism, so that its front end is accurately at the center of the working area of the bending tooling.

[0053] S2 Adjust the bending angle setting of the bending tooling according to the angle required for the automotive air intake curtain buckle;

[0054] S21 Obtain relevant technical materials or design drawings according to the bending angle required for the automotive air intake curtain buckle to determine the angle value;

[0055] Specifically, according to the angle required for the automotive air intake curtain buckle, consult relevant technical materials or design drawings to determine the accurate angle value.

[0056] S22 Drive the bending tooling to adjust the angle by rotating the angle adjustment handwheel.

[0057] Specifically, input this angle value into the PLC controller. The controller drives the motor of the angle adjustment handwheel to drive the handwheel to rotate automatically, thereby driving the mechanical structure inside the bending tooling to adjust the angle. During the adjustment process, the angle sensor monitors the current angle in real time and feeds the data back to the PLC controller. When the preset angle is reached, the controller automatically stops the rotation of the handwheel to complete the angle adjustment process. This angle adjustment device uses a high-resolution angle sensor that can accurately measure angle changes, and its measurement accuracy can reach ±0.01°. At the same time, the PLC controller adopts a PID algorithm, which can effectively reduce the error accumulation and overshoot phenomenon during the angle adjustment process and ensure the accuracy of the bending angle.

[0058] S3 bends the front end of the circlip pliers through a bending tooling to form a bent tip;

[0059] S31 Place the front end of the circlip pliers on the bending die of the bending tooling;

[0060] Specifically, place the front end of the circlip pliers on the bending die of the bending tooling to ensure that the front end of the circlip pliers fits perfectly with the circular arc groove of the lower die.

[0061] S32 Start the power system of the bending tooling to make the upper die move downward and apply pressure to the front end of the circlip pliers;

[0062] Specifically, start the power system of the bending tooling. The power system adopts an efficient hydraulic drive system, which can provide stable and powerful power output. The hydraulic system drives the upper die to move downward, and the circular arc pressing head of the upper die gradually presses against the front end of the circlip pliers. Under the action of pressure, the front end of the circlip pliers gradually undergoes bending deformation.

[0063] S33 When the upper die descends to the set position and the front end of the circlip pliers reaches the required bending angle, the power system stops working and maintains the pressure;

[0064] Specifically, when the upper die descends to the set position and the front end of the circlip pliers reaches the required bending angle, the hydraulic system stops working and maintains the pressure for a period of time to ensure the stability of the bending shape.

[0065] S34 After releasing the pressure and the upper die rises, take out the bent circlip pliers to complete one bending operation.

[0066] Specifically, release the pressure, and the upper die automatically rises to the initial position under the action of the hydraulic system. Take out the bent circlip pliers to complete one bending operation. During the bending process, the bending tooling is equipped with a pressure sensor and a displacement sensor, which can monitor the bending force and the displacement of the upper die in real time. These sensors transmit the data to the PLC controller, and the controller intelligently monitors and controls the bending process according to the preset bending parameters (bending force, displacement amount, time, etc.). If an abnormal situation occurs during the bending process, such as excessive bending force or displacement amount exceeding the allowable range, the controller will automatically stop the bending operation and issue an alarm to prompt the operator to check and adjust, effectively avoiding the problems of circlip pliers damage or unqualified bending quality caused by improper operation.

[0067] S4 performs angle correction and surface treatment on the bent circlip pliers to obtain an air intake curtain buckle pliers.

[0068] S41 Place the circlip pliers on the reference surface of the measuring tool;

[0069] Specifically, place the circlip pliers on the reference surface of the measuring tool. The measuring tool uses a high-precision marble platform, which has good flatness and stability.

[0070] S42 Use an angle measuring tool to measure the angle of the bent tip of the circlip pliers after bending.

[0071] Specifically, use a laser measuring device to measure the angle of the bent tip of the circlip pliers after bending. The laser measuring device can quickly and accurately obtain the angle information of the bent tip and transmit the data to the PLC controller. The PLC controller automatically calculates the amount of fine adjustment required based on the deviation between the measurement result and the preset angle, and controls the bending tooling to perform automatic fine adjustment. By performing a small-scale bending operation again, the angle of the bent tip is adjusted until the precise angle requirement is met.

[0072] S43 Perform surface treatment on the inspected circlip pliers to obtain an air intake curtain buckle pliers.

[0073] Specifically, the surface treatment includes two steps: deburring and rust prevention treatment. Deburring uses a combination of ultrasonic cleaning technology and precision sandpaper grinding. Ultrasonic cleaning can effectively remove the oil and impurities on the surface of the circlip pliers, and precision sandpaper grinding can remove the burrs and sharp edges in the bending area, improving the use safety. Rust prevention treatment uses an environmentally friendly rust prevention coating, which has good adhesion and corrosion resistance and can effectively prevent the circlip pliers from rusting during use and storage. Before applying the rust prevention coating, the surface of the circlip pliers is first cleaned and dried to ensure that the coating can evenly adhere to the surface of the circlip pliers and form a dense protective film.

[0074] Please refer to Figure 6 For the second aspect, an air intake curtain buckle pliers for an automobile is prepared by using the method for bending the tip of the air intake curtain buckle pliers for an automobile described in the first aspect, and includes a pliers body and two bent tips. The two bent tips are located at the front end of the pliers body and are symmetrical to each other.

[0075] In this embodiment, the symmetrical design enables the buckle pliers to apply force evenly when taking the air intake curtain buckle, avoiding the situation of buckle damage or inability to take it off due to uneven force. The shape and size of the bent tip are precisely calculated and optimized, and can perfectly match the shape of the air intake curtain buckle of the automobile, improving the success rate and efficiency of taking the buckle.

[0076] Please refer to Figures 7 to 9 For the third aspect, a bending tooling for the tip of an air intake curtain buckle pliers for an automobile is used for the method for bending the tip of the air intake curtain buckle pliers for an automobile described in the first aspect, and includes a workbench 101 and a fixture mechanism. The fixture mechanism includes a rotating assembly, a bidirectional screw 102, two sleeves 103, two connecting rods 104, two clamping plates 105 and two abutting plates 106;

[0077] The rotating assembly is installed on one side of the workbench 101. The bidirectional screw 102 is rotatably connected to the workbench 101 and is connected to the rotating assembly. The two sleeves 103 are respectively threadedly connected to the bidirectional screw 102 and are located around the bidirectional screw 102. The two connecting rods 104 are respectively fixedly connected to the two sleeves 103 and are respectively located on one side of the two sleeves 103. The two clamping plates 105 are respectively fixedly connected to the two connecting rods 104 and are respectively located on the two connecting rods 104. The two abutting plates 106 are respectively fixedly connected to the workbench 101 and are respectively located on the workbench 101.

[0078] When it is necessary to clamp an ordinary circlip pliers, place the ordinary circlip pliers between the two abutting plates 106 and the two clamping plates 105, and rotate the rotating assembly. The rotating assembly drives the bidirectional screw 102 to rotate. The bidirectional screw 102 drives the two sleeves 103 to move away from each other. The two sleeves 103 drive the two clamping plates 105 on the two connecting rods 104 to move towards the side close to the abutting plates 106 until the two clamping plates 105 clamp the ordinary circlip pliers, and thus the fixation of the ordinary circlip pliers can be completed, solving the problem of low efficiency of the traditional fixing method.

[0079] The rotating assembly includes a turntable 107, a worm 108 and a worm gear 109. The turntable 107 is rotatably connected to the workbench 101 and is located on one side of the workbench 101. The worm 108 is fixedly connected to the turntable 107 and is rotatably connected to the workbench 101. The worm gear 109 is fixedly connected to the bidirectional screw 102, meshes with the worm 108, and is rotatably connected to the workbench 101.

[0080] Rotating the turntable 107 can drive the worm 108 to rotate. The rotation of the worm 108 can drive the worm gear 109 to rotate. The rotation of the worm gear 109 can drive the bidirectional screw 102 to rotate.

[0081] The fixture mechanism further includes a guide rail 110 and two guide blocks 111. The guide rail 110 is fixedly connected to the workbench 101 and is located inside the workbench 101. The two guide blocks 111 are respectively slidably connected to the guide rail 110 and are respectively located between the two sleeves 103 and the guide rail 110. The guide rail 110 provides an installation condition for the two guide blocks 111, and the two guide blocks 111 can guide and limit the two sleeves 103.

[0082] The fixture mechanism further includes a clamping block 112 and a return spring 113. The clamping block 112 is slidably connected to the workbench 101 and is located on one side of the workbench 101. The return spring 113 is fixedly connected to the clamping block 112, and is fixedly connected to the workbench 101 and is located between the workbench 101 and the clamping block 112. The turntable 107 has a plurality of clamping holes, and the clamping block 112 can cooperate with the corresponding clamping holes to limit the turntable 107, and the return spring 113 can spring the clamping block 112 into the corresponding clamping hole by its resilience.

[0083] When it is necessary to clamp an ordinary circlip pliers, place the ordinary circlip pliers between the two abutting plates 106 and the two clamping plates 105. After moving the clamping block 112 out of the turntable 107, rotate the turntable 107. The turntable 107 drives the worm 108 to rotate, the worm 108 drives the worm gear 109 to rotate, the worm gear 109 drives the bidirectional screw 102 to rotate, the bidirectional screw 102 drives the two sleeves 103 to move away from each other, and the two sleeves 103 drive the two clamping plates 105 on the two connecting rods 104 to move toward the side close to the abutting plate 106 until the two clamping plates 105 clamp the ordinary circlip pliers, thus completing the fixation of the ordinary circlip pliers, and solving the problem of low efficiency of the traditional fixing method.

[0084] Beneficial effects:

[0085] First, the present invention effectively improves work efficiency: By bending the ordinary circlip pliers into a shape suitable for taking the airbag buckle, the maintenance personnel can complete the taking of the buckle in a shorter time, without repeatedly adjusting the tool or trying different methods, thus significantly improving the efficiency of the maintenance work, reducing the maintenance time, and improving customer satisfaction.

[0086] Second, the present invention enhances the operation convenience: The bent tip at the front end of the bent circlip pliers matches the shape of the airbag buckle of the car, making it easier and more accurate to take the buckle.
