Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile, more specifically, the utility model relates to a kind of automobile steering wheel skeleton detection tooling. BACKGROUND

[0002] Automobile steering wheel skeleton detection tooling is the key equipment to guarantee the quality and performance of steering wheel. It covers two types of general and special, such as general tooling, go-stop gauge, which can detect size precision and other conventional indicators. In special tooling, there are devices based on sensors and three-dimensional scanners that can accurately obtain data and analyze defects. The steering wheel skeleton bending detection machine also belongs to special tooling, which simulates bending conditions to monitor parameters to evaluate quality and ensure compliance with safety standards.

[0003] The steering wheel skeleton bending detection machine mainly consists of a loading device, a fixing device, and a measurement control system. The loading device can apply different forces to bend the skeleton, and the fixing device ensures the stability of the skeleton. The measurement control system can accurately measure and control the loading process. During operation, the skeleton is first fixed, and the loading device applies force according to the set program to bend the skeleton. The measurement control system monitors the deformation and stress of the skeleton in real time, and determines whether the skeleton meets the bending performance standards based on these data, thereby completing the detection.

[0004] In the prior art, some automobile steering wheel skeleton detection tooling usually uses rigid contact for clamping when clamping the steering wheel skeleton, and is still fixed by traditional bolts during clamping. The rigid contact tooling cannot adapt to the actual shape of the skeleton, which may cause loose clamping or excessive local stress. Loose clamping may cause the skeleton to shake during detection, affecting the detection accuracy. Excessive local stress may further exacerbate the deformation of the skeleton, even causing damage to the skeleton, affecting product quality and subsequent performance. In addition, the use of bolts requires machining corresponding bolt holes on the steering wheel skeleton and the detection tooling, and then tightening the bolts to achieve fixation. This process is relatively cumbersome, increasing the assembly time and labor cost. Especially in batch detection, frequent bolt installation and removal can reduce detection efficiency and affect production progress. UTILITY MODEL CONTENTS

[0005] To overcome the above-mentioned defects of the prior art, the utility model provides an automobile steering wheel skeleton detection tooling to solve the problem of using rigid contact for clamping when clamping the steering wheel skeleton in the prior art, and still fixing by traditional bolts during clamping.

[0008] The locking assembly comprises a pressing plate, the outer side of the pressing plate is slidably connected to the inner wall of the fixed block, the inner wall of the pressing plate is fixedly connected with a pull column, the outer side of the pull column is sleeved with a spring two, the outer side of the pull column is movably connected with a clamping block, the outer side of the clamping block is fixedly connected with a movable block, the inner wall of the movable block is fixedly connected with a clamping pin, and the outer side of the clamping pin is movably connected with two connecting blocks.

[0009] One end of the two connecting blocks away from the clamping pin is fixedly connected to the inner wall of the fixed block, and the outer side of the movable block is in contact with the outer side of the fixed block.

[0010] The outer side of the top block is slidably connected to the inner wall of the fixed block, and one end of the spring one away from the sliding plate is fixedly connected to the inner wall of the fixed block.

[0011] The outer side of the snap ring is in contact with the inner wall of the fixed block, and one end of the rubber strip away from the fixed block is in contact with the outer side of the snap ring.

[0012] The outer side of the pull column is slidably connected to the inner wall of the movable block, and the outer side of the spring two is fixedly connected to the outer side of the pressing plate.

[0013] One end of the pressing plate away from the spring two is fixedly connected to the inner wall of the movable block, and one end of the clamping block away from the movable block is movably connected to the inner wall of the fixed block.

[0014] Compared with the prior art, the utility model has the advantages that:

[0015] In the above scheme, the steering wheel skeleton is fixed on the fixed column in the support, the movable block is opened, the air cylinder is started to move downward, the snap ring contacts the steering wheel skeleton, and then the movable block is closed. The fixed block is driven downward by the air cylinder, the snap ring is acted on by the steering wheel skeleton, and the spring one is extruded by the sliding plate; the sliding plate is pressed and circulates between compression and potential energy release, ensuring that the snap ring continuously adheres to the steering wheel skeleton, and pushing the snap ring to extrude the rubber strip between the snap ring and the fixed block when being compressed, the rubber strip avoids rigid contact of components, prevents the sliding plate from excessively extruding the spring one, and the two snap rings cooperate with each other to tightly fix the steering wheel skeleton, reduces the safety hidden danger, and prolongs the service life of the equipment.

[0016] In the above scheme, by setting the locking assembly, by pulling the pull column, the pull column drives the pressing plate to exert pressure on itself, spring two shrinks, and the space for the pull column to completely enter the fixed block is released.

[0023] In order to make the technical problems, technical schemes and advantages to be solved by the utility model more clear, specific embodiments will be described in detail below with reference to the drawings.

[0024] As shown in the accompanying Figure 1 to the accompanying Figure 4 The embodiment of the utility model provides a kind of automobile steering wheel skeleton detection tool, including

[0025] The bracket 1 provides a base platform for the structure of the whole detection tooling and is an important guarantee for the stable work of the whole tooling. The bracket 1 is fixedly connected with two air cylinders 2 outside. The air cylinders 2 serve as a power source and can provide power support. Through the extension and retraction action, the air cylinders 2 can realize the fixation of the steering wheel skeleton and realize the up-and-down reciprocating movement after fixation to test the bending degree of the steering wheel skeleton. The driving end of each air cylinder 2 is fixedly connected with a fixed block 3. The fixed block 3 can transmit the power of the air cylinder 2 and plays a role of connecting and transmitting power. The inner wall of the fixed block 3 is slidably connected with a sliding plate 4. The sliding plate 4 can slide flexibly on the inner wall of the fixed block 3. It can move according to the actual situation to realize the close fitting of the steering wheel skeleton. The outer part of the sliding plate 4 is fixedly connected with a top block 5. The top block 5 plays a role of transmitting the force of the sliding plate 4 and transmits the force of the sliding plate 4 to the clamping ring 7, so as to fix the steering wheel skeleton. The end of the sliding plate 4 away from the top block 5 is fixedly connected with a spring 6. The spring 6 plays a role of buffering and adjusting in the whole tooling. When the clamping ring 7 contacts the steering wheel skeleton, the spring 6 will be compressed and released potential energy according to the pressure, so that the clamping ring 7 can better fit the steering wheel skeleton. The end of the top block 5 away from the sliding plate 4 is fixedly connected with a clamping ring 7. The clamping ring 7 is directly in contact with and fixed to the steering wheel skeleton. Through the interaction with the steering wheel skeleton, the clamping ring 7 realizes the fixation of the steering wheel skeleton. The inner wall of the fixed block 3 is fixedly connected with two rubber strips 8. The rubber strips 8 are arranged between the clamping ring 7 and the fixed block 3. When the clamping ring 7 moves under pressure, the rubber strips 8 will be squeezed. The existence of the rubber strips 8 avoids the rigid contact between the components and prevents the sliding plate 4 from excessively pressing the spring 6, thereby playing a role of protecting the components and stabilizing the fixation. The inner wall of the fixed block 3 is slidably connected with a locking assembly for locking the subsequent components. The locking assembly plays a role of locking the clamping ring 7 after it fits the steering wheel skeleton, so as to ensure the stability of the steering wheel skeleton during the detection process and prevent loosening.

[0026] The locking assembly comprises a pressing plate 9, which is an important component in the locking assembly and plays a key role in the locking process. It can be moved under the driving of the pull column 10, thereby realizing the control of the components. The outer wall of the pressing plate 9 is slidingly connected to the inner wall of the fixed block 3, which enables the pressing plate 9 to slide flexibly inside the fixed block 3 and provides space. The inner wall of the pressing plate 9 is fixedly connected with the pull column 10, which is used to control the movement of the pressing plate 9. By pulling or loosening the pull column 10, the operation of the pressing plate 9 is realized, thereby controlling the working state of the locking assembly. The outer part of the pull column 10 is sleeved with a spring 11, which plays a role in buffering and resetting during the operation of the pull column 10. When the pull column 10 is pulled or loosened, the spring 11 will correspondingly contract or stretch to ensure that the pull column 10 can be operated smoothly. The outer part of the pull column 10 is movably connected with a clamping block 12, which plays a key locking role in the locking assembly. When the movable block 13 drives the clamping block 12 into the inside of the fixed block 3, the clamping block 12 will be clamped with the inner wall of the fixed block 3, realizing the locking of the steering wheel skeleton. The outer part of the clamping block 12 is fixedly connected with a movable block 13, which is used to control the movement of the clamping block 12. By operating the movable block 13, the clamping block 12 is driven to move accordingly, thereby realizing the functions of locking and unlocking. The inner wall of the movable block 13 is fixedly connected with a clamping pin 14, which plays a role in connecting the movable block 13 and the connecting block 15, enabling the movable block 13 to rotate around the clamping pin 14, thereby realizing its operation function. The outer part of the clamping pin 14 is movably connected with two connecting blocks 15, which are fixedly connected to the inner wall of the fixed block 3. Their movable connection with the clamping pin 14 provides support and connection for the rotation of the movable block 13, ensuring that the movable block 13 can be operated smoothly.

[0027] The ends of the two connecting blocks 15 away from the clamping pin 14 are fixedly connected to the inner wall of the fixed block 3. This connection mode ensures the stability of the connecting block 15, thereby enabling the movable block 13 to rotate stably around the clamping pin 14. The outer part of the movable block 13 is in contact with the outer part of the fixed block 3. This design makes the movable block 13 more stable during operation, and also facilitates its operation.

[0028] The outer part of the top block 5 is slidingly connected to the inner wall of the fixed block 3. The sliding connection of the top block 5 inside the fixed block 3 enables it to move with the sliding plate 4, thereby accurately transmitting the force of the sliding plate 4 to the clamping ring 7. The end of the spring 6 away from the sliding plate 4 is fixedly connected to the inner wall of the fixed block 3. This connection mode ensures that the spring 6 can work stably. When the sliding plate 4 is subjected to pressure, the spring 6 can be compressed and released potential energy accordingly.

[0029] The outer part of the clamping ring 7 is in contact with the inner wall of the fixed block 3, which makes the clamping ring 7 keep stable in the fixed block 3 and facilitates the contact and fixation with the steering wheel framework. The end of the rubber strip 8 away from the fixed block 3 is in contact with the outer part of the clamping ring 7, and when the clamping ring 7 is moved under pressure, the rubber strip 8 is squeezed, thereby playing a buffering and protection role.

[0030] The outer part of the pull column 10 is slidingly connected to the inner wall of the movable block 13, which makes the pull column 10 move flexibly in the movable block 13, thereby facilitating the control of the pressing plate 9. The outer part of the second spring 11 is fixedly connected to the outer part of the pressing plate 9, which ensures that the second spring 11 can work stably and can be contracted or stretched accordingly when the pull column 10 is pulled or loosened.

[0031] The end of the pressing plate 9 away from the second spring 11 is fixedly connected to the inner wall of the movable block 13, which makes the pressing plate 9 move with the movable block 13, thereby realizing the control of the clamping block 12. The end of the clamping block 12 away from the movable block 13 is movably connected to the inner wall of the fixed block 3, and when the movable block 13 drives the clamping block 12 into the fixed block 3, the clamping block 12 is clamped with the inner wall of the fixed block 3, realizing locking and ensuring that loosening occurs during work;

[0033] Firstly, the steering wheel framework is fixed on the fixed column in the support 1, and then the movable block 13 is punched, at this time, the cylinder 2 is started to move downward, at this time, the clamping ring 7 first contacts the steering wheel framework, and then the movable block 13 is closed, and because the cylinder 2 drives the fixed block 3 to move downward, the clamping ring 7 is squeezed by the slide plate 4 under the influence of the steering wheel framework, and the slide plate 4 is compressed and continuously releases potential energy, so that the clamping ring 7 continues to contact the steering wheel framework, and under the influence of the compression of the slide plate 4, the clamping ring 7 moves, at this time, the clamping ring 7 contacts the rubber strip 8 and is squeezed, and because the rubber strip 8 is between the clamping ring 7 and the fixed block 3, the rigid contact between the components and the excessive pressure of the slide plate 4 on the first spring 6 are avoided, and through the mutual squeezing of the two clamping rings 7, the steering wheel framework is tightly contacted and stably fixed, the safety hidden danger is reduced, and the service life of the equipment is improved.

[0034] In the process of closing the movable block 13, the pull column 10 is pulled, the pull column 10 drives the pressing plate 9 to exert pressure on the pull column 10, and the spring two 11 is retracted to provide enough space for the pull column 10 to completely enter the inside of the fixed block 3, then after complete closing, the movable block 13 drives the clamping block 12 to stay in the inside of the fixed block 3, the pull column 10 is released, at this time, under the action of the spring two 11, the pull column 10 is driven to clamp and fix the clamping block 12, so that the clamping ring 7 is close to the steering wheel skeleton and realizes the bending test of the steering wheel skeleton, and the bending test of the steering wheel skeleton is more stable, and the steering wheel skeleton is quickly fixed and disassembled.
