Description

Technical Field

[0001] This utility model relates to the field of air curtain clip pliers, and in particular to an automotive air curtain clip pliers and a tip bending tool. Background Technology

[0002] In the field of automotive repair and parts replacement, removing airbag clips is a common and important operation. Traditionally, repair personnel have relied primarily on standard snap ring pliers to accomplish this task. However, standard snap ring pliers are not specifically designed for removing airbag clips, resulting in numerous inconveniences and limitations in practical operation.

[0003] First, the shape and structure of ordinary snap ring pliers do not match the shape of car air curtain clips, which means that more time and effort are needed to adjust and adapt when removing the clips. This not only reduces work efficiency, but may also damage the clips or car parts due to improper operation.

[0004] Currently, existing bending fixtures require fixing both legs of the ordinary snap ring pliers separately when processing them, resulting in low fixing efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a car air intake curtain clip pliers and a tip bending tool, which aims to solve the problem of low efficiency of traditional fixing methods.

[0006] To achieve the above objectives, in a first aspect, this utility model provides a tooling for bending the tip of automotive air intake curtain clip pliers, including a worktable and a clamping mechanism, wherein the clamping mechanism includes a rotating assembly, a bidirectional screw, two sleeves, two connecting rods, two clamping plates, and two abutting plates;

[0007] The rotating assembly is installed on one side of the worktable. The bidirectional screw is rotatably connected to the worktable and connected to the rotating assembly. The two sleeves are threadedly connected to the bidirectional screw and are located around the bidirectional screw. The two connecting rods are fixedly connected to the two sleeves and are located on one side of the two sleeves. The two clamping plates are fixedly connected to the two connecting rods and are located on the two connecting rods. The two abutting plates are fixedly connected to the worktable and are located on the worktable.

[0008] The rotating assembly includes a turntable, a worm gear, and a worm wheel. The turntable is rotatably connected to the worktable and is located on one side of the worktable.

[0009] The clamping mechanism further includes a guide rail and two guide blocks. The guide rail is fixedly connected to the worktable and located inside the worktable. The two guide blocks are slidably connected to the guide rail and are located between the two sleeves and the guide rail.

[0010] The clamping mechanism further includes a locking block and a return spring. The locking block is slidably connected to the worktable and is located on one side of the worktable. The return spring is fixedly connected to the locking block and the worktable, and is located between the worktable and the locking block.

[0011] Secondly, a car air intake curtain clip clamp is prepared using the tip bending tool of the car air intake curtain clip clamp described in the first aspect, comprising a clamp body and two curved tips, wherein the two curved tips are located at the front end of the clamp body and are symmetrical to each other.

[0012] Thirdly, a method for bending the tip of automotive curtain air pleats, using the tip bending fixture for automotive curtain air pleats described in the first aspect, includes the following steps:

[0013] Secure the ordinary snap ring pliers to the bending fixture;

[0014] Adjust the bending angle setting of the bending fixture according to the required angle of the car air intake curtain buckle;

[0015] The front end of the snap ring pliers is bent using a bending fixture to form a curved tip;

[0016] The angle of the bent snap ring clamps is corrected and the surface is treated to obtain the air curtain snap clamps.

[0017] The step of "fixing ordinary snap ring pliers onto a bending fixture" includes the following steps:

[0018] Place the snap ring pliers in the clamp of the fixing device, so that the pliers are tightly fitted against the inner wall of the clamp;

[0019] By tightening the clamping bolts, the clamp applies a clamping force to the snap ring pliers, ensuring that the snap ring pliers will not shift during bending.

[0020] Use the positioning block to fine-tune the position of the snap ring pliers so that its front end is in the center of the working area of ​​the bending fixture.

[0021] The step of "adjusting the bending angle setting of the bending fixture according to the required angle of the car air intake curtain clip" includes the following steps:

[0022] Obtain relevant technical data or design drawings based on the required bending angle of the car air intake curtain clip, and determine the angle value;

[0023] The bending fixture can be adjusted by rotating the angle adjustment handwheel.

[0024] The step of "bending the front end of the snap ring pliers to form a bent tip using a bending fixture" includes the following steps:

[0025] Place the front end of the snap ring pliers onto the bending die of the bending fixture;

[0026] Start the power system of the bending fixture to move the upper die downward and apply pressure to the front end of the snap ring clamp;

[0027] When the upper die descends to the set position, and the front end of the snap ring clamp reaches the required bending angle, the power system stops working and maintains pressure;

[0028] After the pressure is released and the upper die rises, remove the bent snap ring clamp to complete one bending operation.

[0029] The step of "performing angle correction and surface treatment on the bent snap ring pliers to obtain the air curtain snap pliers" includes the following steps:

[0030] Place the snap ring pliers on the reference surface of the measuring tool;

[0046] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0047] Please see Figures 7 to 9Thirdly, a tooling for bending the tip of automotive air intake curtain clip pliers, used in the method for bending the tip of automotive air intake curtain clip pliers described in the first aspect, includes a workbench 101 and a clamping mechanism, the clamping mechanism including a rotating assembly, a bidirectional screw 102, two sleeves 103, two connecting rods 104, two clamping plates 105 and two abutting plates 106.

[0048] The rotating assembly is installed on one side of the worktable 101. The bidirectional screw 102 is rotatably connected to the worktable 101 and connected to the rotating assembly. The two sleeves 103 are threadedly connected to the bidirectional screw 102 and are located around the bidirectional screw 102. The two connecting rods 104 are fixedly connected to the two sleeves 103 and are located on one side of the two sleeves 103. The two clamping plates 105 are fixedly connected to the two connecting rods 104 and are located on the two connecting rods 104. The two supporting plates 106 are fixedly connected to the worktable 101 and are located on the worktable 101.

[0049] When it is necessary to clamp the ordinary snap ring pliers, place the ordinary snap ring pliers on the two supporting plates 106 and the two clamping plates 105 brackets, 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 closer to the supporting plates 106 until the two clamping plates 105 clamp the ordinary snap ring pliers, thus completing the fixation of the ordinary snap ring pliers, thereby solving the problem of low efficiency of traditional fixation methods.

[0050] The rotating assembly includes a turntable 107, a worm gear 108, and a worm wheel 109. The turntable 107 is rotatably connected to the worktable 101 and is located on one side of the worktable 101. The worm gear 108 is fixedly connected to the turntable 107 and rotatably connected to the worktable 101. The worm wheel 109 is fixedly connected to the bidirectional screw 102, meshes with the worm gear 108, and is rotatably connected to the worktable 101.

[0051] Rotating the turntable 107 can drive the worm gear 108 to rotate, the rotation of the worm gear 108 can drive the worm wheel 109 to rotate, and the rotation of the worm wheel 109 can drive the bidirectional screw 102 to rotate.

[0052] The clamping mechanism further includes a guide rail 110 and two guide blocks 111. The guide rail 110 is fixedly connected to the worktable 101 and located within the worktable 101. The two guide blocks 111 are 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 the installation conditions for the two guide blocks 111, which can guide and limit the two sleeves 103.

[0053] The clamping mechanism further includes a locking block 112 and a return spring 113. The locking block 112 is slidably connected to the worktable 101 and located on one side of the worktable 101. The return spring 113 is fixedly connected to the locking block 112 and the worktable 101, and is located between the worktable 101 and the locking block 112. The turntable 107 has multiple locking holes. The locking block 112, in conjunction with the corresponding locking hole, can limit the turntable 107. The return force of the return spring 113 can spring the locking block 112 into the corresponding locking hole.

[0054] When clamping a standard snap ring pliers, place the pliers on the two support plates 106 and the two clamping plates 105 brackets. After removing the locking block 112 from the turntable 107, rotate the turntable 107. The turntable 107 drives the worm gear 108 to rotate, which in turn drives the worm wheel 109 to rotate. The worm wheel 109 drives the bidirectional screw 102 to rotate, which in turn 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 closer to the support plates 106 until the two clamping plates 105 clamp the standard snap ring pliers. This completes the fixing of the standard snap ring pliers, solving the problem of low efficiency in traditional fixing methods.

[0055] Please see Figure 6 Secondly, a car air curtain clip clamping pliers, using the car air curtain clip clamping tip bending method tooling described in the first aspect, includes a clamp body and two bent tips, the two bent tips being located at the front end of the clamp body and symmetrical to each other.

[0056] In this embodiment, the symmetrical design allows the clip pliers to apply force evenly when removing the air curtain clip, avoiding damage or failure to remove the clip due to uneven force. The shape and size of the curved tip have been precisely calculated and optimized to perfectly match the shape of the car's air curtain clip, improving the success rate and efficiency of clip removal.

[0057] Please see Figures 1 to 5Thirdly, a method for bending the tip of automotive curtain air intake clip pliers, using the tip bending fixture for automotive curtain air intake clip pliers described in the first aspect, includes the following steps:

[0058] S1 secures a standard snap ring clamp to a bending fixture;

[0059] S11 places the snap ring clamp in the clamping mechanism of the fixing device, so that the clamp body of the snap ring clamp fits tightly against the inner wall of the clamping mechanism;

[0060] Specifically, the bending fixture's fixing device employs a mechanical clamping mechanism. The inner wall of this mechanism is designed with grooves that match the shape of the snap ring pliers, ensuring even force distribution and preventing slippage during clamping. The clamping bolts are made of high-strength alloy steel, providing sufficient clamping force while also exhibiting good wear resistance and fatigue resistance. The snap ring pliers are inserted by aligning their jaws with the grooves in the clamping mechanism, ensuring a tight fit between the jaws and the inner wall of the mechanism.

[0061] S12 tightens the clamping bolts to apply clamping force to the snap ring clamps, ensuring that the snap ring clamps do not shift during bending.

[0062] Specifically, use a wrench to tighten the clamping bolts and apply clamping force according to the preset torque value to ensure that the snap ring pliers do not shift during bending.

[0063] S13 uses a positioning block to fine-tune the position of the snap ring pliers, so that its front end is in the center of the working area of ​​the bending fixture.

[0064] Specifically, the position of the snap ring pliers is finely adjusted using a positioning block. The positioning block, through a precision threaded adjustment mechanism, can accurately adjust the position of the snap ring pliers in three-dimensional space, ensuring that its front end is precisely centered in the working area of ​​the bending fixture.

[0065] S2 adjusts the bending angle setting of the bending fixture according to the required angle of the car air intake curtain buckle;

[0066] S21 obtains relevant technical data or design drawings based on the bending angle required for the car air intake curtain buckle, and determines the angle value;

[0067] Specifically, based on the required angle of the car's air intake curtain clip, consult relevant technical documents or design drawings to determine the accurate angle value.

[0068] S22 uses a rotating angle adjustment handwheel to drive the bending fixture to adjust its angle.

[0069] Specifically, the angle value is input into the PLC controller, which drives the motor of the angle adjustment handwheel, causing the handwheel to rotate automatically. This, in turn, drives the internal mechanical structure of the bending fixture 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, completing the angle adjustment process. This angle adjustment device uses a high-resolution angle sensor, which can accurately measure angle changes with a measurement accuracy of ±0.01°. Simultaneously, the PLC controller employs a PID algorithm, which effectively reduces error accumulation and overshoot during the angle adjustment process, ensuring the accuracy of the bending angle.

[0070] S3 uses a bending fixture to bend the front end of the snap ring pliers to form a bent tip;

[0071] S31 places the front end of the snap ring pliers onto the bending die of the bending fixture;

[0072] Specifically, place the front end of the snap ring pliers onto the bending die of the bending fixture, ensuring that the front end of the snap ring pliers is fully engaged with the arc-shaped groove of the lower die.

[0073] S32 starts the power system of the bending fixture, causing the upper die to move downward and apply pressure to the front end of the snap ring clamp;

[0074] Specifically, the power system of the bending fixture is activated. The power system adopts a high-efficiency hydraulic drive system, which can provide stable and powerful power output. The hydraulic system drives the upper die to move downward, and the arc-shaped pressure head of the upper die gradually presses against the front end of the snap ring clamp. Under the pressure, the front end of the snap ring clamp gradually bends and deforms.

[0075] When the upper die descends to the set position and the front end of the snap ring clamp reaches the required bending angle, the power system stops working and maintains pressure.

[0076] Specifically, when the upper die descends to the set position and the front end of the snap ring clamp reaches the required bending angle, the hydraulic system stops working and maintains pressure for a period of time to ensure the stability of the bent shape.

[0077] After the upper die recovers from the pressure release of S34, the bent snap ring clamp is removed, completing one bending operation.

[0078] Specifically, after the pressure is released, the upper die automatically returns to its initial position under the action of the hydraulic system, removing the bent snap ring clamp and completing one bending operation. During the bending process, the bending fixture is equipped with pressure and displacement sensors, which can monitor the bending force and the displacement of the upper die in real time. These sensors transmit data to the PLC controller, which intelligently monitors and controls the bending process according to preset bending parameters (bending force, displacement, and time, etc.). If any abnormality occurs during the bending process, such as excessive bending force or displacement 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 problems such as damage to the snap ring clamp or substandard bending quality caused by improper operation.

[0079] S4 performs angle correction and surface treatment on the bent snap ring pliers to obtain the air intake curtain snap pliers.

[0080] S41 places the snap ring clamp on the reference surface of the measuring tool;

[0081] Specifically, place the snap ring clamp on the reference surface of the measuring tool, which uses a high-precision marble platform with good flatness and stability.

[0082] S42 uses an angle measuring tool to measure the angle of the bent tip of the snap ring pliers after bending.

[0083] Specifically, a laser measuring device is used to measure the angle of the bent tip of the snap ring pliers. This device quickly and accurately acquires the angle information and transmits the data to the PLC controller. Based on the deviation between the measurement result and the preset angle, the PLC controller automatically calculates the required fine-tuning amount and controls the bending fixture to perform automatic fine-tuning. By performing another small bend, the angle of the bent tip is adjusted until the precise angle requirement is met.

[0084] S43 performs surface treatment on the tested snap ring clamps to obtain the air curtain snap clamps;

[0085] Specifically, the surface treatment includes two steps: deburring and rust prevention. Deburring uses a combination of ultrasonic cleaning and precision sandpaper polishing. Ultrasonic cleaning effectively removes oil and impurities from the surface of the snap ring pliers, while precision sandpaper polishing removes burrs and sharp edges from bending areas, improving safety during use. Rust prevention uses an environmentally friendly rust-preventive coating. This coating has excellent adhesion and corrosion resistance, effectively preventing the snap ring pliers from rusting during use and storage. Before applying the rust-preventive coating, the surface of the snap ring pliers is cleaned and dried to ensure the coating adheres evenly and forms a dense protective film.

[0086] Beneficial effects:

[0087] I. This utility model effectively improves work efficiency: By bending ordinary snap ring pliers into a shape suitable for the air curtain buckle, maintenance personnel can complete the removal of the buckle in a shorter time without having to adjust tools multiple times or try different methods, thereby significantly improving the efficiency of maintenance work, reducing maintenance time, and increasing customer satisfaction.

[0088] II. This utility model enhances ease of operation: The bent tip of the snap ring pliers matches the shape of the car air curtain clip, making the clip removal easier and more accurate. Maintenance personnel can more intuitively align the clip, apply force more naturally and evenly, reducing operational difficulty and physical exertion, and lowering the risk of errors due to inconvenient operation.

[0089] Third, this utility model improves repair quality: The precisely bent snap ring pliers better adapt to the structure of the air curtain clips, ensuring protection of the clips and automotive parts during clip removal. This avoids damage or deformation of the clips caused by unsuitable tools, guaranteeing the quality and reliability of repair work and extending the service life of automotive parts.

[0090] IV. Cost Reduction: This method eliminates the need for specialized and expensive tools. Simply bending existing ordinary snap ring pliers is sufficient to meet the requirements for air curtain clips. This saves auto repair businesses and individuals on tool purchase costs and reduces resource waste caused by idle tools, thus optimizing resource utilization.

[0091] V. This utility model has strong versatility: By adjusting the bending angle and shape, this bending method can adapt to different models and types of automotive air curtain clips. This allows repair personnel to use the same bent snap ring pliers to handle various repair scenarios, improving the tool's versatility and flexibility, and enhancing its practicality in actual work.

[0092] The above description is merely a preferred embodiment of the automotive air intake curtain clip pliers and tip bending tool of this utility model. Of course, it should not be construed as limiting the scope of this utility model.
