Abstract

This invention relates to the field of stress testing technology for new energy vehicle parts, specifically a connecting rod internal stress testing device for new energy vehicles. It mainly includes a body with a slide rail installed on its inner wall, a movable sleeve slidably installed on the outer wall of the slide rail, and a support plate installed on the top surface of the movable sleeve. It also includes: a fixing mechanism located inside the body; a blowing mechanism located inside the body, comprising a fixed box fixedly installed on the side of a support frame; and a rotating mechanism located inside the body. When the connecting rod is clamped and fixed by a clamping plate, the connecting rod pushes the push block and support bar to move. The support bar drives the piston plate to move, and the piston plate pushes the gas inside the fixed box to be discharged from a one-way valve and a hose to an air outlet pipe. The gas is then sprayed from multiple nozzles through the air outlet pipe to blow away particles from the surface of the connecting rod. This prevents the detector from being affected by particles during connecting rod testing, thereby improving the accuracy of connecting rod internal stress detection in new energy vehicles.

Description

Technical Field

[0001] This invention relates to the field of stress testing technology for new energy vehicle parts, specifically to a device for testing the internal stress of connecting rods in new energy vehicles. Background Technology

[0002] New energy vehicles utilize unconventional vehicle fuels or novel onboard power systems, combined with advanced power control and drive technologies, resulting in a type of vehicle with advanced technical principles and novel technologies and structures. This encompasses various types, including pure electric vehicles, hybrid electric vehicles, range-extended electric vehicles, fuel cell electric vehicles, and hydrogen engine vehicles. The connecting rod, a core component of hybrid electric vehicles and a key part of the engine or motor transmission system, directly affects the performance, lifespan, and safety of the entire vehicle due to its internal stress state. Given the high-speed, high-efficiency, and high-reliability development requirements of new energy vehicles, connecting rod internal stress testing is particularly important.

[0003] When testing the internal stress of connecting rods in new energy vehicles, the connecting rod is fixed directly by the testing equipment, and the internal stress at a single point on the surface of the connecting rod is detected by the detector. During the production process, impurity particles remaining on the surface of the connecting rod can block the detector, causing abnormal test results and thus affecting the accuracy of the internal stress test of the connecting rod.

A fixing strip is fixedly installed on the side of the support frame. An air outlet pipe is set above the fixing strip. Multiple nozzles are fixedly installed through the outer wall of the air outlet pipe. A support strip is slidably installed through the side of the fixed box.

[0009] The rotating mechanism is located inside the machine body. The rotating mechanism includes a rotating bar that is fixedly installed on the outer wall of the air outlet duct, a cylinder that is fixedly installed on the side of the rotating bar, and a connecting plate that is fixedly installed on the side of the support bar.

[0010] Preferably, the top surface of the support plate has two T-shaped grooves, and T-shaped blocks are slidably installed on the inner walls of the two T-shaped grooves. The top surfaces of the two T-shaped blocks are respectively fixedly connected to the bottom surfaces of the two support frames.

[0011] Preferably, the bottom surface of the support plate has a groove, the inner wall of the groove is fixedly installed with a motor, the lower end of the motor is fixedly installed with a rotating plate, and the bottom surface of the rotating plate has two arc-shaped grooves.

[0012] Preferably, an adjusting rod is fixedly installed on the bottom surface of each of the two T-shaped blocks, and a through groove is opened through the bottom of the T-shaped groove. The outer wall of the adjusting rod is slidably connected to the inner wall of the through groove and the inner wall of the arc groove.

[0013] Preferably, a piston plate is slidably installed on the inner wall of the fixing box, and the side of the piston plate is fixedly connected to one end of the support bar. A placement groove is opened on the inner wall of the clamping plate, and a push block is slidably installed on the inner wall of the placement groove. One end of the support bar slides through the outer wall of the clamping plate and is fixedly connected to the side of the push block.

[0014] Preferably, the side of the piston plate is elastically connected to the inner wall of one side of the fixed box through an elastic element, and a connecting sleeve is fixedly installed on the top surface of the fixing strip. The inner wall of the connecting sleeve is rotatably connected to the outer wall of one end of the air outlet pipe through a bearing seat.

[0015] Preferably, an air inlet pipe is fixedly installed through the side of the fixed box, and a one-way valve is installed on the air inlet pipe. A flexible hose is connected to the side of the fixed box through a second one-way valve, and one end of the flexible hose is connected to the air outlet pipe.

[0016] Preferably, a T-shaped groove is provided on the side of the fixing strip, a T-shaped block is slidably installed on the inner wall of the T-shaped groove, and a connecting strip is fixedly installed on the side of the T-shaped block.

[0017] Preferably, the T-shaped block has adjustment grooves on both sides, and the inner wall of the adjustment groove is slidably connected to the outer wall of the cylinder.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] When the connecting rod is clamped and fixed by the clamping plate two, the connecting rod pushes the push block and the support bar to move. The support bar drives the piston plate to move. The piston plate pushes the gas inside the fixing box to be discharged from the one-way valve two and the hose to the air outlet pipe. The gas is sprayed out from multiple nozzles through the air outlet pipe to blow away the particles on the surface of the connecting rod. This ensures that the detector will not be affected by the particles when detecting the connecting rod, thereby improving the accuracy of the detection of internal stress of the connecting rod in new energy vehicles.

[0021] When the support bar moves, it drives the connecting plate to move. The inclined groove on the connecting plate drives the fixed column and the connecting bar to move. The connecting bar drives the T-block II to move. The adjustment groove on the T-block II drives the cylinder and the rotating bar to rotate at a certain angle, which in turn drives the air outlet pipe and the nozzle to rotate at a certain angle. The nozzle thoroughly removes particles from the surface of the connecting rod, further ensuring the accuracy and quality of the test.

[0022] By turning on the motor, the rotating plate is rotated at a certain angle. The two arc-shaped grooves on the rotating plate drive the two adjusting rods and T-block 1 to move. The two T-block 1 drive the two support frames to move. The two support frames drive clamping plates 1 and 2 to clamp and fix the connecting rod, making it less likely for the connecting rod to deviate or move during detection, thereby improving the accuracy of the detection.

[0046] The blowing mechanism 3 is located inside the body 1. The blowing mechanism 3 includes a fixed box 301 fixedly installed on the side of the support frame 203. A fixing strip 311 is fixedly installed on the other side of the support frame 203. An air outlet pipe 313 is provided above the fixing strip 311. Multiple nozzles 314 are fixedly installed through the outer wall of the air outlet pipe 313. The support strip 303 is slidably installed through the side of the fixed box 301.

[0047] Specifically, such as Figures 1-8 As shown, a piston plate 302 is slidably installed on the inner wall of the fixed box 301. The side of the piston plate 302 is fixedly connected to one end of the support bar 303. A placement groove 305 is opened on the inner wall of the clamping plate 205.

[0048] In this embodiment: When the connecting rod is clamped by the clamping plate 205, the connecting rod squeezes the push block 304 through the push block 304. The movement of the push block 304 drives the support bar 303 and the piston plate 302 to move.

[0049] Specifically, such as Figures 1-8 As shown, the side of the piston plate 302 is elastically connected to the inner wall of one side of the fixed box 301 through the elastic element 306. The top surface of the fixing strip 311 is fixedly installed with a connecting sleeve 312. The inner wall of the connecting sleeve 312 is rotatably connected to the outer wall of one end of the air outlet pipe 313 through the bearing seat.

[0050] In this embodiment: the elastic element 306 applies elastic force to the piston plate 302, and the inner wall of the connecting sleeve 312 is rotatably connected to the outer wall of one end of the air outlet pipe 313 through the bearing seat, so that the air outlet pipe 313 can rotate at a certain angle.

A hose 310 is connected to the side of the fixed box 301 through a one-way valve 309. One end of the hose 310 is connected to the air outlet pipe 313.

[0052] In this embodiment, by setting one-way valve 308 and one-way valve 309, the fixed box 301 can only take in air from the air inlet pipe 307 and take out air from the hose 310.

[0053] Rotating mechanism 4 is located inside the body 1. Rotating mechanism 4 includes a rotating bar 403 fixedly installed on the outer wall of the air outlet duct 313, a cylinder 404 fixedly installed on the side of the rotating bar 403, and a connecting plate 408 fixedly installed on the side of the support bar 303.

[0055] In this embodiment: the T-shaped groove 401 is used to limit the movement of the T-shaped block 402, so that the T-shaped block 402 and the connecting strip 406 can move more stably.

[0056] Specifically, such as Figures 1-8 As shown, the side of the T-shaped block 402 is provided with an adjustment groove 405, and the inner wall of the adjustment groove 405 is slidably connected to the outer wall of the cylinder 404.

[0060] Specifically, the solution is as follows: The connecting rod is placed on the arc-shaped plate 206. The motor 210 is turned on, causing the rotating plate 211 to rotate at a certain angle. The two arc-shaped grooves 212 on the rotating plate 211 drive the two adjusting rods 208 and T-block 1 202 to move. The two T-blocks 1 202 drive the two support frames 203 to move. The two support frames 203 drive the clamping plate 1 204 and clamping plate 205 to clamp and fix the connecting rod. When clamping plate 205 clamps and fixes the connecting rod, the connecting rod pushes the push block 304 and support bar 303 to move. The support bar 303 drives the piston plate 302 to move. The piston plate 302 pushes the gas inside the fixed box 301 to be discharged from the one-way valve 2 309 and hose 310 to the air outlet 313. The air outlet 313 sprays particles from multiple nozzles 314 to remove them from the surface of the connecting rod. When the support bar 303 moves, it drives the connecting plate 408 to move. The inclined groove 409 on the connecting plate 408 drives the fixed column 407 and the connecting bar 406 to move. The connecting bar 406 drives the T-block 402 to move. The adjusting groove 405 on the T-block 402 drives the cylinder 404 and the rotating bar 403 to rotate at a certain angle, which in turn drives the air outlet 313 and the nozzles 314 to rotate at a certain angle. The nozzles 314 thoroughly remove the particles from the surface of the connecting rod. The moving assembly 104 is activated to move the electric push rod 105 and the detector 106 to a suitable position. The electric push rod 105 is activated to drive the detector 106 to detect the connecting rod.
