Abstract
Description
Technical Field
[0001] This invention relates to the field of instrument panel tube beam inspection technology, and more particularly to an instrument panel tube beam end clamping device. Background Technology
[0002] Traditional testing methods for inspecting the opening accuracy of instrument panel tube beam assemblies have certain drawbacks. Typically, when placing the instrument panel tube beam assembly on the testing equipment, only one end of the tube beam is clamped. This single-sided clamping method makes the tube beam highly susceptible to uneven stress during testing, leading to instability such as twisting, shifting, or wobbling. For example, if the other end of the tube beam is not fixed during precise measurements, it may shift due to slight impacts from the measuring head or its own unstable center of gravity, resulting in inaccurate test results that fail to reflect the actual opening accuracy of the tube beam. Furthermore, this instability can affect the normal operation of the testing equipment, increasing the risk of collisions between the equipment and the tube beam, reducing testing efficiency, and potentially damaging the testing equipment or the tube beam assembly itself.
[0003] Meanwhile, when faced with complex inspection requirements that necessitate multi-angle and multi-directional testing of opening accuracy, single-sided clamping is insufficient. This is because the pipe beam assembly cannot maintain a stable and consistent state under different inspection angles and positions, resulting in a cumbersome inspection process and difficulty in guaranteeing accuracy, thus limiting further optimization and improvement of the inspection technology. Summary of the Invention
[0004] The purpose of this invention is to provide a clamping device for the end of an instrument panel tube beam, which aims to solve the problem that the existing single-sided clamping method is prone to causing instability of the tube beam and affecting the accuracy of beam tube detection when detecting the opening accuracy of the instrument panel tube beam assembly.
[0005] To achieve the above objectives, the present invention provides an instrument panel tube beam end clamping device, including a base and a clamping mechanism. The clamping mechanism includes a mounting bracket, a lower clamping plate, a drive assembly, a screw, a sleeve, a movable frame, an upper clamping plate, and a fixing assembly.

[0012] This invention discloses an instrument panel tube beam end clamping device. The base provides installation conditions for the clamping mechanism. When clamping the instrument panel tube beam, the instrument panel tube beam is placed between the lower clamping plate and the upper clamping plate. The driving assembly is rotated, which drives the screw to rotate. The screw drives the sleeve to move, and the sleeve moves the moving frame. The mounting frame moves the upper clamping plate closer to the lower clamping plate until the lower clamping plate contacts and clamps the instrument panel tube beam.

[0021] In this embodiment, the base 1 provides the installation conditions for the clamping mechanism. When it is necessary to clamp the instrument panel tube beam, the instrument panel tube beam is placed between the lower clamping plate 3 and the upper clamping plate 7. The drive assembly is rotated, and the drive assembly drives the screw 4 to rotate. The screw 4 drives the sleeve 5 to move, and the movement of the sleeve 5 drives the movement frame 6 to move. The mounting frame 2 drives the upper clamping plate 7 to move closer to the lower clamping plate 3 until the lower clamping plate 3 contacts the instrument panel tube beam and clamps it. Then, the fixing assembly is moved to the middle of the instrument panel tube beam. By fixing the middle of the instrument panel tube beam with the fixing assembly, the instrument panel tube beam can be prevented from loosening during inspection. This solves the problem that the existing single-sided clamping method easily leads to tube beam instability and affects the beam tube inspection accuracy when inspecting the opening accuracy of the instrument panel tube beam assembly.
[0022] Furthermore, the drive assembly includes a turntable 8, a worm gear 9, and a worm wheel 10. The turntable 8 is rotatably connected to the base 1 and located on one side of the base 1.

[0025] In this embodiment, the turntable 8 has multiple locking holes. The locking block 11 can limit the turntable 8 by cooperating with the corresponding locking hole. The locking block 11 can be pushed into the corresponding locking hole by the rebound force of the reset spring 12. The pull rod 13 can be pulled to the side away from the turntable 8 by the pull rod 13.
[0026] Furthermore, the clamping mechanism also includes a guide rail 14 and a guide block 15. The guide rail 14 is fixedly connected to the mounting frame 2 and located inside the mounting frame 2. The guide block 15 is slidably connected to the guide rail 14 and fixedly connected to the sleeve 5, and located between the guide rail 14 and the sleeve 5.
[0027] In this embodiment, the guide rail 14 provides installation conditions for the guide block 15. The guide block 15 can guide and limit the sleeve 5, thereby improving the stability of the sleeve 5 when it moves.
[0028] Furthermore, the fixing assembly includes a sliding member, a support base 16, a limiting member, a sliding rod 17, a second return spring 18, and a supporting plate 19.

[0029] In this embodiment, the sliding member can drive the support seat 16 to move, and the support seat 16 can support the lower side of the instrument panel beam. The limiting member can limit the sliding member to prevent the sliding seat from shifting. The slide rod 17 can drive the abutment plate 19 to move, adjusting the distance between the abutment plate 19 and the support seat 16. The abutment plate 19, in conjunction with the support seat 16, can clamp and limit the instrument panel beam. The return spring 18 can reset the slide rod 17.
[0030] Furthermore, the sliding component includes a slide rail 23, a slide plate 24, and a connecting frame 25. The slide rail 23 is fixedly connected to the base 1 and is located on the base 1.

The base 1 has multiple fixing holes, and the fixing frame 21, in conjunction with the corresponding fixing holes, can limit the connecting frame 25 and prevent it from shifting. The rebound force of the limiting spring 22 can spring the fixing frame 21 into the corresponding fixing hole.
[0034] When clamping the instrument panel beam is required, the instrument panel beam is placed between the lower clamping plate 3 and the upper clamping plate 7. The locking block 11 is pulled away from the turntable 8 by the pull rod 13. The turntable 8 is rotated, which drives the worm gear 9 to rotate. The worm gear 9 drives the worm wheel 10 to rotate. The worm wheel 10 drives the screw 4 to rotate. The screw 4 drives the sleeve 5 to move. The movement of the sleeve 5 drives the moving frame 6 to move. The mounting bracket 2 drives the upper clamping plate 7 to move closer to the lower clamping plate 3 until the lower clamping plate 3 contacts the instrument panel beam and clamps it. Pull the abutment plate 19 until it moves to a preset position. Then, move the fixing frame 21 away from the base 1 via the moving rod 20, push the connecting frame 25 to the preset position, release the abutment plate 19, and reset the pull rod 13 by the rebound force of the limiting spring 22. By limiting the middle part of the instrument panel tube beam with the abutment plate 19 and the support seat 16, the instrument panel tube beam can be prevented from loosening during inspection. This solves the problem that the existing single-sided clamping method is prone to causing tube beam instability and affecting the beam tube inspection accuracy when inspecting the opening accuracy of the instrument panel tube beam assembly.
