Abstract
Description
Technical Field
[0001] This application relates to the field of automotive parts testing technology, specifically to a force measuring mechanism for an automotive plastic lever. Background Technology
[0002] Automotive plastic levers are plastic control components installed inside a car (usually located on either side of the steering wheel or in the center console area) to control various vehicle functions, such as lights, wipers, turn signals, cruise control, and gear shifting. They convert operational actions into electrical signals through mechanical or electronic means, thereby triggering the corresponding functions. Because automotive plastic levers are frequently subjected to tensile and bending forces during use, tensile and bending force testing must be performed on them after production to ensure their strength.
[0003] Currently, all automotive plastic levers are tested manually. This involves workers first fixing the lever in a specialized fixture, then using two different force-measuring tools to test its pull-out and bending forces. After testing, the levers must be manually removed and sorted according to the results. This cumbersome process leads to low efficiency. Furthermore, it's difficult to maintain a consistent grip angle and operating speed for the force-measuring tools during manual testing, resulting in significant errors and low accuracy. In addition, prolonged continuous work leads to high labor intensity and labor costs, necessitating a solution. Summary of the Invention

The first feed end 2131 of the first discharge chute 213 is located at the rear lower part of the pull bar 27.
[0021] A force measuring mechanism for a car plastic lever further includes a feeding device 3 located on the top of a base plate 1 and behind a detection body 2. The feeding device 3 includes a base frame 31 fixed on the base plate 1, a U-shaped storage block 33 fixed on the top of the base frame 31, a blocking cylinder 38 fixed on the top of the base frame 31 and located to the left of the U-shaped storage block 33, and an L-shaped stop block 39 fixed on the telescopic end of the blocking cylinder 38. The telescopic end of the blocking cylinder 38 is arranged laterally to the right, and the rear right outer wall of the L-shaped stop block 39 cooperates with the left opening of the U-shaped storage block 33.
[0022] The feeding device 3 also includes a top frame 32 fixed to the top of the base frame 31, a shifting cylinder 34 fixed inside the top frame 32, a positioning block 310 and a transfer cylinder 35 fixed to the telescopic end of the shifting cylinder 34 to achieve forward and backward translational movement through the shifting cylinder 34 and respectively arranged in front and behind, and a transition rod 36 and an anti-deviation rod 37 that slide along the front and back direction and are laterally inserted and connected in the positioning block 310 and respectively arranged in front and behind. The telescopic end of the transfer cylinder 35 is arranged laterally forward and fixed to the rear end of the transition rod 36 and the anti-deviation rod 37. The front outer wall of the positioning block 310 cooperates with the right rear outer wall of the L-shaped stop block 39.
[0023] The feeding device 3 also includes a feeding guide rail 311 that is horizontally fixed on the base plate 1 and located to the right of the U-shaped storage block 33. The left end opening of the feeding guide rail 311 cooperates with the right side opening of the U-shaped storage block 33.
[0024] The detection body 2 also includes a material dispensing cylinder 214 fixed inside the base frame 31 and a second discharge chute 215 fixed at the telescopic end of the material dispensing cylinder 214 at an inclination relative to the horizontal plane. The second feed end 2151 of the second discharge chute 215 is located in front of the pulling bar 27 and is higher than the first feed end 2131 of the first discharge chute 213.
[0025] The rear outer wall of the positioning block 23 has vertically distributed guide grooves 231. Two vertically arranged and symmetrically distributed limiting strips 216 are fixed between the rear outer walls of the positioning block 23 and the guide block 26. The positioning rod 25 slides in the front-back direction and is laterally inserted into the bottom of the guide groove 231.
[0026] A vertically installed protective plate 217 is also fixed on the outer walls of both the left and right sides of the guide block 26.
[0027] A first stepped notch 3101 is formed on the upper edge of the front outer wall of the alignment block 310, and a second stepped notch 391 is formed on the upper edge of the right rear outer wall of the L-shaped stop block 39, which cooperates with the first stepped notch 3101.
[0028] Working principle: Using a vibratory feeder or manually, a certain number of plastic levers 4 are placed vertically onto the feed guide rail 311 through the opening at the right end of the feed guide rail 311, with the head of each plastic lever 4 positioned above the feed guide rail 311, so that the tail 41 of the plastic lever 4 is inserted into the feed guide rail 311. A through hole 42 is formed between the outer walls of the front and rear sides of the head of the plastic lever 4, and a first waist-shaped hole 44 and a second waist-shaped hole 43 are formed in the tail 41 of the plastic lever 4, which are respectively arranged vertically.
[0029] When the first plastic lever 4 leaves the left end opening of the feed guide rail 311, its tail 41 will enter the interior of the U-shaped storage block 33 through the right opening of the U-shaped storage block 33 and continue to move to the left under the push of the subsequent plastic lever 4. The head of the plastic lever 4 is located above the top opening of the U-shaped storage block 33.
[0030] Next, the telescopic end of the blocking cylinder 38 in the drive feeding device 3 extends outward to drive the L-shaped blocking block 39 to move to the right until the right outer wall of the L-shaped blocking block 39 is blocked by the left outer wall of the U-shaped storage block 33. At the same time, the telescopic end of the drive displacement cylinder 34 extends outward to drive the alignment block 310 and the transfer cylinder 35 to move forward until the front outer wall of the alignment block 310 is a certain distance away from the right rear outer wall of the L-shaped blocking block 39. When the first plastic lever 4 leaves the left opening of the U-shaped storage block 33, its tail 41 is located between the front outer wall of the alignment block 310 and the right rear outer wall of the L-shaped blocking block 39, and its head is located between the first stepped notch 3101 and the second stepped notch 391 to prevent the plastic lever 4 from falling.
[0031] Next, the telescopic end of the drive transfer cylinder 35 extends outward to drive the adapter rod 36 and the anti-deviation rod 37 to move forward, thereby inserting the front ends of the adapter rod 36 and the anti-deviation rod 37 into the through hole 42 and the first waist-shaped hole 44, respectively. Then, the telescopic end of the drive stop cylinder 38 retracts inward to drive the L-shaped stop block 39 to move to the left until the distance between the right outer wall of the L-shaped stop block 39 and the left outer wall of the U-shaped storage block 33 is greater than the left and right widths of the head and tail 41 of the plastic lever 4.
[0032] Next, the telescopic end of the shift cylinder 34 is driven to extend outward, causing the alignment block 310 and the transfer cylinder 35 to move forward. Then, with the help of the adapter rod 36 and the anti-deviation rod 37, the plastic lever 4 moves forward until the front outer wall of the tail 41 of the plastic lever 4 is attached to the rear outer wall of the pull bar 27 in the execution unit of the detection body 2. At this time, the traction block 271 is inserted into the second waist-shaped hole 43. Then, the telescopic end of the positioning cylinder 24 in the positioning unit is driven to extend outward, causing the positioning rod 25 to move backward, so that the rear end of the positioning rod 25 is gradually inserted into the through hole 42. At the same time, the telescopic end of the shift cylinder 34 is driven to retract inward, so that the adapter rod 36 and the anti-deviation rod 37 move backward in the same way, so that the front ends of the adapter rod 36 and the anti-deviation rod 37 gradually leave the through hole 42 and the first waist-shaped hole 44, respectively, thereby transferring and fixing the plastic lever 4 onto the positioning rod 25.
[0033] Next, the telescopic end of the thrust cylinder 211 in the actuator unit is first driven to retract inward so as to drive the push bar 210 forward with the help of the second strain block 212 until the rear end of the push bar 210 is completely separated from the pull bar 27. Then, the telescopic end of the pull cylinder 28 in the actuator unit is driven to retract inward so as to drive the pull bar 27 downward with the help of the first strain block 29. Then, the lower outer wall of the traction block 271 and the lower inner wall of the first waist-shaped hole 44 apply a downward pulling force to the tail 41 of the plastic lever 4. The first strain block 29 is connected to the detection equipment through the wire. The first strain block 29 will monitor the magnitude of the pulling force on the tail 41 in real time during the above process and send the pulling force value to the detection equipment. When the pulling force value reaches the set value and the tail 41 has not broken, it indicates that the tensile strength of the plastic lever 4 is qualified (existing technology).
[0034] If the tensile strength of the plastic lever 4 is qualified, the telescopic end of the pulling cylinder 28 is first driven to extend outward to move the pulling strip 27 upward and reset in the same way, thus putting the plastic lever 4 in an unloaded state; then the telescopic end of the thrust cylinder 211 is driven to extend outward to move the push strip 210 backward with the help of the second strain block 212, so that the rear end of the push strip 210 gradually extends to the rear outside of the pulling strip 27 and gradually approaches the end of the tail 41 of the plastic lever 4. When the push strip 210 is driven to move backward, the rear end of the push strip 210... A backward force is applied to the end of the tail 41 of the plastic lever 4. Since the rear end of the positioning rod 25 is always inserted into the through hole 42, the head of the plastic lever 4 remains stationary. The second strain gauge 212 is connected to the detection device via an electric wire. The second strain gauge 212 will monitor the bending force on the tail 41 in real time during the above process and send the bending force value to the detection device. When the bending force value reaches the set value and the tail 41 has not broken, it indicates that the bending resistance of the plastic lever 4 is qualified (existing technology).
[0035] If either the tensile strength or bending strength of the plastic lever 4 fails the test, the telescopic end of the drive positioning cylinder 24 will retract inward to move the positioning rod 25 forward, thereby causing the rear end of the positioning rod 25 to gradually leave the through hole 42. When the rear end of the positioning rod 25 completely leaves the through hole 42, the fixed connection between the plastic lever 4 and the pull bar 27 will disappear. The plastic lever 4 will fall due to its own weight, causing the upper inner wall of the second waist-shaped hole 43 to slide along the guide slope 272. As a result, the plastic lever 4 will move backward while falling, and finally fall into the first feed end 2131 of the first discharge chute 213. Then, it will be automatically output outward along the slope of the first discharge chute 213 and through the first discharge end 2132 of the first discharge chute 213.
[0036] If the tensile and bending strength of the plastic lever 4 are both tested and qualified, the telescopic end of the drive dispensing cylinder 214 will extend outward to drive the second discharge chute 215 forward and gradually approach the pull bar 27. Then, the telescopic end of the drive positioning cylinder 24 will retract inward in the same way to drive the positioning rod 25 forward until the rear end of the positioning rod 25 is completely away from the through hole 42. The plastic lever 4 will fall into the second feed end 2151 of the second discharge chute 215 and then automatically output outward along the slope of the second discharge chute 215 and through the second discharge end 2152 of the second discharge chute 215, without falling into the first feed end 2131 of the first discharge chute 213.
[0037] This invention can automatically complete the positioning of automotive plastic levers and the sequential detection of pull-out and bending forces without manual operation. After the detection is completed, it can automatically classify and output the automotive plastic levers based on the detection results. It can also automatically feed and transfer the automotive plastic levers with the help of the feeding device 3, thereby greatly simplifying the operation steps and effectively improving work efficiency. At the same time, it can effectively ensure that the angle and speed of the force applied to the plastic lever 4 during detection are uniform, thereby reducing detection errors and improving detection accuracy. In addition, it also reduces labor intensity and lowers labor costs.
[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
