Description

Technical Field

[0001] This utility model relates to the field of automotive component testing technology, and in particular to an aluminum chassis control arm testing component and a chassis parts quality inspection tool. Background Technology

[0002] During the testing of automotive parts, aluminum chassis control arms need to undergo fatigue strength testing. Common testing devices use a fixture to clamp the control arm onto a platform and apply a reciprocating load to one end through a drive device to achieve the testing effect.

[0003] However, the existing control arm has a single fixed platform. When testing the other side of the control arm is required, due to the irregular shape of the control arm, the workpiece cannot be directly flipped to adjust the workstation, often requiring the replacement of another set of fixtures. This operation method increases the inspection time and requires additional workstations. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology, which requires changing fixtures and multiple workstations, and to propose an aluminum chassis control arm detection component and chassis parts quality inspection tool.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An aluminum chassis control arm detection assembly includes a base;

[0007] A rotating base is located on the front of the base. A rotating shaft is fixedly installed at the center point of the back of the rotating base. One end of the rotating shaft passes through the back of the base and is rotatably mounted via a bearing.

[0008] A vertical fixing seat and a horizontal fixing seat are respectively fixedly installed on both sides of the front of the rotating seat. A horizontal support rod is fixedly installed on the side wall of the vertical fixing seat, and a slot is opened on the top of the horizontal fixing seat.

[0009] A vertical sliding seat and a horizontal sliding seat are slidably disposed on both sides of the front of the rotating seat. A limit groove is provided on the side wall of the vertical sliding seat. A vertical support rod is fixedly disposed at the bottom of the horizontal sliding seat. The same connecting seat is fixedly disposed between the vertical sliding seat and the horizontal sliding seat.

[0010] The back of the base has sliding holes on both sides of the center point of the rotating seat. A retaining plate is slidably disposed inside the sliding hole. One end of the retaining plate slides through the rotating seat and cooperates with the connecting seat.

[0011] A drive unit and a sleeve, wherein a steering seat is rotatably mounted on the top of the sleeve, and the drive unit is connected to the steering seat.

[0012] In one possible design, the base has a torsion ring rotatably mounted inside, the pivot is located inside the torsion ring, the outer wall of the torsion ring has two spiral and centrally symmetrical guide grooves, two retaining plates are located on both sides of the torsion ring, the side wall of the retaining plates is fixedly provided with guide blocks, the sliding hole is connected to the installation position of the torsion ring, and the guide block cooperates with the guide groove on the same side.

[0013] In one possible design, one end of the torsion ring extends to the outside of the base and is provided with a handwheel. A secondary cylinder is fixedly provided on the back of the base. The rotating shaft is located inside the secondary cylinder, and the secondary cylinder is located inside the torsion ring. A torsion spring is sleeved on the outer wall of the secondary cylinder, and the two ends of the torsion spring are respectively connected to the outer wall of the secondary cylinder and the inner wall of the torsion ring.

[0014] In one possible design, the drive component is a hydraulic cylinder, and the end of the hydraulic cylinder's telescopic shaft is fixedly connected to the steering seat.

[0015] In one possible design, the rotation point of the rotating seat is located at its center point, and the card plate is inserted to both sides of the center point of the rotating seat.

[0016] A chassis parts quality inspection tool, including the aforementioned aluminum chassis control arm inspection assembly, further includes:

[0017] The platform has a gantry frame fixedly installed on one side of its top, and a base fixedly installed on the other side of the platform's top. A movable seat is slidably installed on the crossbeam of the gantry frame. A hydraulic cylinder is installed on the side wall of the movable seat. A motor is fixedly installed on the vertical section of the gantry frame. A threaded rod is rotatably installed inside the crossbeam of the gantry frame. The movable seat is threaded onto the outer wall of the threaded rod. The output shaft of the motor is fixedly connected to the end of the threaded rod.

[0018] In this application, during actual use, the wheel end of the control arm body is sleeved onto the transverse support rod from the side, while the frame end is located at the top of the transverse fixed seat. Then, the sliding connecting seat is slidable, causing the vertical sliding seat and the transverse sliding seat to move. At this time, the vertical sliding seat will move to one side of the wheel end to limit it, and the limiting groove will be sleeved on the surface of the transverse support rod. The transverse sliding seat will move to the top of the frame end to limit it, and the vertical support rod passes through the mounting hole of the frame end and is inserted into the inside of the slot, thereby completing the installation of the control arm body.

[0019] By rotating the torsion ring with the handwheel, the guide groove on the surface rotates, which in turn moves the guide block along the guide groove, thereby driving the card plate to move laterally. When the card plate is inserted into the interior of the rotating seat, it will fix the rotating seat and prevent it from rotating. Conversely, it will release the fixation and flip the rotating seat. When the card plate passes through the rotating seat and fits against the side wall of the connecting seat, it will limit the connecting seat and prevent it from moving, thus fixing the main body of the control arm. Since the rotation point of the rotating seat is located at its center point, and the card plate is inserted on both sides of the center point of the rotating seat, even after the rotating seat drives the main body of the control arm to rotate 180 degrees, the card plate can still continue to be inserted into one side of the connecting seat to limit its movement.

[0020] The drive motor drives the threaded rod to rotate, thereby controlling the lateral displacement of the moving seat. This adjusts the hydraulic cylinder to move it above the other end of the control arm body, and the sleeve is tilted to a suitable angle with the end of the frame and fitted onto its end. Then, the hydraulic cylinder is driven to move the sleeve downwards and reciprocate to press the control arm body, thus conducting a fatigue test.

[0021] In this utility model, the aluminum chassis control arm detection assembly and chassis parts quality inspection tool can simultaneously limit and fix the wheel end and frame end of the control arm through a multi-directional sliding seat, thereby improving the clamping efficiency.

[0022] In this utility model, the aluminum chassis control arm detection component and chassis parts quality inspection tool can achieve the locking and releasing of the rotating seat by the lateral cooperation of the spiral guide groove on the surface of the torsion ring and the clamping plate, and at the same time limit the connecting seat, so as to fix the workpiece in both forward and reverse states.

[0023] In this invention, during use, the rotatable mounting base allows for in-situ flipping and adjustment, thereby directly achieving the effect of reverse detection. Thus, a single detection component and station of this size can achieve bidirectional detection. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] In one embodiment: Reference Figure 1 An aluminum chassis control arm detection assembly includes: a base 1, a rotating seat 2, a fixed seat, a sliding seat, etc.

[0033] refer to Figure 3 The base 1 is fixedly mounted on the detection platform 27, and a rotating shaft 13 is rotatably mounted on its front side via bearings. The rear end of the rotating shaft 13 extends to the back of the base 1, and its front end is fixedly connected to the center point of the back of the rotating seat 2. A rotatable torsion ring 19 is installed inside the base 1, located around the rotating shaft 13. One end of the torsion ring 19 extends out of the base 1 and is fixed with a handwheel for easy manual operation. Two centrally symmetrical spiral guide grooves 18 are formed on the outer wall of the torsion ring 19. Sliding holes 20 are formed on both sides of the back of the base 1 at the center point of the rotating seat 2, and a retaining plate 5 is slidably mounted in each sliding hole 20. A guide block 15 is fixed to the side wall of the retaining plate 5, and the guide block 15 passes through the sliding hole 20 and embeds into the guide groove 18 on the same side. When the handwheel is turned to rotate the torsion ring 19, the guide groove 18 pushes the guide block 15, thereby driving the retaining plate 5 to slide laterally along the sliding hole 20. An auxiliary cylinder 17 is also sleeved outside the rotating shaft 13. A torsion spring 16 is connected between the auxiliary cylinder 17 and the torsion ring 19. The torsion spring 16 can provide a reset torque.

[0034] refer to Figure 2On the front sides of the rotating base 2, vertical fixing seats 3 and horizontal fixing seats 6 are fixed by bolts or welding, respectively. A horizontal support rod 7 for supporting the wheel end of the control arm 4 is fixed to the side wall of the vertical fixing seat 3. A slot 8 is provided at the top of the horizontal fixing seat 6. On the front sides of the rotating base 2, corresponding to the two fixing seats, vertical sliding seats 9 and horizontal sliding seats 11 are slidably arranged via slide rails, and the two are fixedly connected as one unit by a connecting seat 14. A limit groove 10 is provided on the side wall of the vertical sliding seat 9. A vertical support rod 12 is fixed to the bottom of the horizontal sliding seat 11.

[0035] refer to Figure 3 For the test area, the top of the sleeve 23 is rotatably equipped with a steering seat 22, which is rotatably connected to the end of the telescopic shaft of the hydraulic cylinder 21, so that the sleeve 23 can adapt to the tilt angle.

[0036] Specifically, the wheel end of the aluminum control arm body 4 is fitted onto the transverse support rod 7, while one of its frame ends is placed on top of the transverse fixing seat 6. Then, the sliding connecting seat 14 moves the vertical sliding seat 9 and the transverse sliding seat 11 together. The vertical sliding seat 9 moves to the side of the wheel end, and its limiting groove 10 fits onto the surface of the transverse support rod 7, achieving lateral limiting of the wheel end. Simultaneously, the transverse sliding seat 11 moves above the frame end, and its bottom vertical support rod 12 inserts downwards into the mounting hole at the frame end, and finally into the slot 8, thus completing the initial clamping of the control arm body 4.

[0037] By controlling the rotation of the torsion ring 19, the two locking plates 5 can be driven to move towards the center of the rotating seat 2 through the cooperation of the guide groove 18 and the guide block 15. When the locking plates 5 are inserted into the rotating seat 2, the rotating seat 2 can be locked to prevent it from rotating. If the locking plates 5 further penetrate the rotating seat 2 and fit against the side wall of the connecting seat 14, the connecting seat 14 can be locked at the same time to prevent it from sliding, thereby achieving the fastening of the control arm.

[0038] The sleeve 23 is tilted to a suitable angle and fitted onto the end of the frame. Then, the hydraulic cylinder 21 is activated, causing the sleeve 23 to reciprocate and press the control arm, performing a bending fatigue test. After the test, the control arm's quality can be assessed by observation. If it is necessary to flip the control arm to inspect the other side and perform a reverse test, simply turn the handwheel in the opposite direction to disengage the locking plate 5 from the rotating seat 2, allowing the rotating seat to be manually flipped 180 degrees. Since the locking plate 5 is located on both sides of the center point of the rotating seat, it can be reinserted after flipping and will limit the connection seat 14, ensuring the stability of the workpiece after flipping. Furthermore, during flipping, the operator can manually stabilize the connection seat 14 to ensure balance. Figure 1 and Figure 5 These represent the states before and after the flip, respectively.

[0039] This application can be used in the field of automotive parts testing, or in other fields applicable to this application.

[0040] In another embodiment: Reference Figure 6 A chassis parts inspection tool includes the aforementioned aluminum chassis control arm inspection assembly, applied to the field of automotive parts inspection. It also includes a platform 27 and a gantry 24 fixed to one side of the top, with a base 1 mounted on the other side of the platform 27. A threaded rod driven by a motor 25 is rotatably installed within the crossbeam of the gantry 24. A movable seat 26 slides on the crossbeam of the gantry 24 while being threaded onto the threaded rod, thus moving laterally under the drive of the motor 25, thereby positioning the hydraulic cylinder 21.

[0041] When fatigue testing is required, start motor 25 and adjust hydraulic cylinder 21 to be directly above the other end of the control arm frame to match the position of the control arm body 4 after it is flipped.

[0042] However, as is well known to those skilled in the art, the working principles and wiring methods of the motor 25 and the hydraulic cylinder 21 are conventional means or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0043] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
