The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0042] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.
[0043] Please see Figure 1 and Figure 2This embodiment provides a stress relief device 200 for a new vehicle off-line. The stress relief device 200 can be installed on a test bench 100 with a receiving cavity 110. It should be understood that the test bench 100 can be an additionally constructed test bench structure, or the receiving cavity 110 can be designed at the test site, and then the stress relief device 200 is fixedly installed within the receiving cavity 110. Figure 2 For ease of description, direction A in the diagram is defined as the vertical direction. For the newly produced target vehicle 300, in order to release the stress of the target vehicle 300, the target vehicle 300 can be moved above the stress release device 200. According to the wheelbase, track width and stress release requirements of different vehicle models, the positions of the four vibration actuators of the stress release device 200, as well as the vibration frequency, amplitude and vibration time length that the vibration actuators need to provide, are controlled and adjusted by electronic devices. At this time, the vehicle will vibrate up and down along direction A in the diagram to release stress.
[0044] It should be noted that the transfer of the target vehicle 300 to the stress relief device 200 can actually be achieved using existing technology. For example, the target vehicle 300 can be pre-lifted and transferred to a preset position using a lifting device, and then lowered to place the target vehicle 300 on the stress relief device 200. Of course, other methods can also be used, and specific settings can be selectively configured according to actual needs.
[0045] Of course, a support steel plate can also be installed in the cavity 110 of the stress relief device 200. For example, when stress relief is required for a certain vehicle model, corresponding through holes can be pre-drilled in the support plate to facilitate the lifting and lowering of the four vibration actuators of the stress relief device 200. The target vehicle 300 is driven to the corresponding position by the support steel plate, and then the stress relief device 200 is activated to relieve stress on the target vehicle 300.
[0046] Please see Figures 3 to 5For ease of description, direction B in the diagram is defined as the first direction, and direction C as the second direction. The first and second directions are perpendicular to each other. The stress relief device 100 for new vehicle production line includes a base 210, a first support seat 220, and a vibration actuator 230. A first slide rail 211 along the first direction is provided on the surface of the base 210. Two first slide rails 211 can be arranged in parallel at intervals. The first slide rails 211 are fixedly connected to the base 210. Two first support seats 220 are slidably connected to the first slide rails 211 along the second direction. Specifically, a slider adapted to the first slide rail 211 is provided on the bottom surface of the first support seat 220. A second slide rail 221 along the second direction is provided on the surface of each first support seat 220. Four vibration actuators 230 are provided. Every two vibration actuators 230 are slidably connected to each second slide rail 221. The vibration actuators 230 are used to support the vehicle after production line and provide the vehicle with a vertically adjustable vibration force.
[0047] In some embodiments, a first motor 212 is fixedly installed on the surface of a base 210 between two first slide rails 211. The output shaft of the first motor 212 is fixedly connected to a first lead screw 213 arranged along a first direction. The first lead screw 213 is respectively connected to two first support seats 220 for transmission. The other end of the first lead screw 213 is rotatably connected to a first support block 214. The first support block 214 is fixedly arranged on the surface of the base 210. Specifically, the two first support seats 220 are provided with threaded sleeves that cooperate with the first lead screw 213. When the first lead screw 213 rotates, it controls the two first support seats 220 to move in opposite directions along the first direction.
[0048] Combination Figure 4 For the first lead screw 213, the surface of the first lead screw 213 is provided with a first threaded section 2131 and a second threaded section 2132 with opposite thread directions. A lead screw nut for use with the first lead screw 213 is provided in the first support seat 220. In this way, when the first lead screw 213 rotates, it drives the two first support seats 220 to move in opposite directions along the first direction. The first lead screw 213 is set between the two first slide rails 211 to facilitate the balance of the two first support seats 220 during adjustment.
[0049] In some embodiments, the surface of the first support base 220 is provided with two parallel second slide rails 221 arranged at intervals along the second direction. Two vibration actuators 230 are slidably connected to the second slide rails 221 through sliders provided on the bottom surface. A second motor 222 is provided on one end surface of the first support base 220. The output shaft of the second motor 222 is fixedly connected to a second lead screw 224. The second lead screw 224 is respectively connected to the two second support bases 231 for transmission, and its other end is rotatably connected to a second support block 223 provided on the surface of the first support base 220. The provision of the second support block 223 makes the transmission process more stable.
[0050] It should be understood that, similar to the first lead screw 213, the surface of the second lead screw 224 is also provided with threaded sections with opposite thread directions. The threaded sections with different helical directions are connected to different vibration actuators 230. The vibration actuator 230 is also provided with a lead screw nut that is matched with the second lead screw 224. When the second lead screw 224 rotates, it drives the two vibration actuators 230 to move in opposite or opposite directions respectively.
[0051] In some embodiments, combined with Figure 5 The vibration actuator 230 includes a second support 231, a hydraulic actuator 232, and a tray 233. The second support 231 is slidably connected to the first slide rail 211. The hydraulic actuator 232 is disposed on the top surface of the second support 231. The tray 233 is disposed at the power output end of the hydraulic actuator 232.
[0052] It should be noted that the specifications of the hydraulic actuator 232 can be selected according to actual needs. Anti-slip texture 2331 can be provided on the top surface of the tray 233. A side guard structure 234 and a front guard structure 251 are provided on the top surface of the tray 233. The side guard structure 234 is provided on the top surface of the tray 233 along the first direction. The front guard structure 251 is provided on the top surface of the tray 233 along the second direction, and together with the side guard structure 234, they form a semi-enclosed area for limiting and fixing the vehicle wheels.
[0053] Optionally, the side guard structure 234 and the front windshield structure 251 can be triangular prisms. Multiple first rubber blocks 2341 can be provided on the surface of the side guard structure 234, and a second rubber block 2351 that fully covers the surface of the front windshield structure 251 can be provided. In this way, while limiting and fixing the target vehicle 300, the tires of the target vehicle 300 can also be better protected.
[0054] It should be noted that the two vibration actuators 230 on the same first support 220 are mirror images of each other, that is, the side guard structures 234 on both sides are opposite each other. The two vibration actuators 230 on the same side of different first support 220 are mirror images of each other. In this way, the four vibration actuators 230 can respectively limit and fix the front and rear wheels of the target vehicle 300 on the side and the front and rear ends, thus ensuring the stability of the target vehicle 300 during stress release.
[0055] In the above embodiment, the new vehicle off-line stress relief device 200, through the setting of vibration actuators 230, can support the four wheels of the vehicle respectively. By controlling the hydraulic actuators 232 of the vibration actuators 230, it can provide stable different vibration frequencies, amplitudes and vibration durations for different vehicle models, avoiding human influence and ensuring the consistency of vehicle stress relief. Through the setting of the first slide rail 211, the first motor 212 and the first lead screw 213, the distance between the two first support seats 220 can be adjusted. Through the setting of the second slide rail 221, the second motor 222 and the second lead screw 223, the distance between the two second support seats 231 can be adjusted. In this way, the new vehicle off-line stress relief device of this application can be adapted to stress relief of vehicle models with different wheelbases and track widths.
