Description

Technical Field

[0001] This application relates to the field of automotive parts testing technology, and in particular to a testing device for automotive power steering plate sealing. Background Technology

[0002] The brake booster plate is a key component of the automotive braking system. Typically, the brake booster plate has multiple studs, each with external threads on its outer wall. The precision of these external threads directly affects assembly accuracy and braking safety. Therefore, it is necessary to check whether the dimensions of the external threads on the studs are within the specified tolerances to ensure they meet the requirements.

[0003] Currently, the inspection of the go / no-go gauges on the external threads of the studs on the end caps mainly relies on manual labor, resulting in low inspection efficiency. Limited by the operators' inspection capabilities, the quality of inspection cannot be guaranteed, leading to poor product consistency.

[0004] The existing technical solutions mentioned above have the following drawbacks: they rely on manual inspection of the go / no-go gauges on the external threads of the studs on the sealing plate, resulting in low inspection efficiency, unreliable inspection quality, and poor product consistency. Summary of the Invention

[0005] To improve testing efficiency, ensure testing quality, and enhance product consistency, this application provides a testing device for automotive power steering plate sealing.

[0006] This application provides a testing device for automotive power steering plate sealing surfaces, which adopts the following technical solution: A testing device for automotive power steering system sealing plates includes: frame; The transfer mechanism, mounted on the frame, is used to move the sealing plate in position. The feeding mechanism, mounted on the frame, is used to supply sealing plates to the transfer mechanism; The unloading mechanism, mounted on the frame, is used to detach the sealing plate from the transfer mechanism; The go gauge inspection mechanism, mounted on the frame, is used to perform go gauge inspection on the external threads of the studs on the end cap. The no-go gauge testing mechanism, mounted on the frame, is used to perform no-go gauge testing on the external threads of the studs on the sealing plate.

[0007] By adopting the above technical solution, the frame provides support. The transfer mechanism moves the sealing plate. The feeding mechanism supplies the sealing plate to be inspected to the transfer mechanism. The unloading mechanism removes the inspected sealing plate from the transfer mechanism. The go gauge inspection mechanism checks the external threads of the studs on the sealing plate located on the transfer mechanism. The no-go gauge inspection mechanism checks the external threads of the studs on the sealing plate located on the transfer mechanism. In this way, it can replace or assist manual inspection of the go and no-go gauges on the external threads of the studs on the sealing plate, effectively improving inspection efficiency, ensuring inspection quality, and resulting in better product consistency.

[0008] This application is further configured such that: there are multiple go gauge inspection mechanisms arranged along the circumference of the transfer mechanism, each used to perform go gauge inspection on the external threads of the corresponding studs on the sealing plate; There are multiple no-go gauge inspection mechanisms, which are alternately set along the circumference of the transfer mechanism with multiple go gauge inspection mechanisms, and are used to perform no-go gauge inspection on the external threads of the corresponding studs on the sealing plate.

[0009] By adopting the above technical solution, as the same sealing plate rotates with the transfer mechanism, multiple go gauge inspection mechanisms sequentially perform go gauge inspection on the external threads of multiple studs on the same sealing plate. Multiple no-go gauge inspection mechanisms sequentially perform no-go gauge inspection on the external threads of multiple studs on the same sealing plate, ensuring the inspection process is carried out in an orderly manner and guaranteeing both inspection efficiency and quality.

The first limiting rod is fixed on the first bracket and located below the first lifting seat; The first detection sensor, fixed on the first bracket, is used to detect the downward movement of the first lifting seat.

[0011] By adopting the above technical solution, the first linear actuator drives the first lifting seat to move downwards, thereby driving the first drive shaft, the first detection ring gauge, and the first rotary actuator to move downwards. Simultaneously, the first rotary actuator drives the first drive shaft to rotate, thereby driving the first flexible coupling and the first detection ring gauge to rotate. When the stud on the sealing plate can be fully screwed into the first detection ring gauge, it proves that the stud meets the go-ahead gauge requirements. When the stud on the sealing plate cannot be fully screwed into the first detection ring gauge, it proves that the stud does not meet the go-ahead gauge requirements. The first detection sensor is used to detect the downward movement of the first lifting seat to determine whether the stud on the sealing plate is fully screwed into the first detection ring gauge. Overall, this improves the go-ahead gauge inspection efficiency, ensures the go-ahead gauge inspection level, and results in better product consistency.

Simultaneously, the second rotary actuator drives the second drive shaft to rotate, thereby rotating the second flexible coupling and the second detection ring gauge. When the stud on the sealing plate cannot be screwed into the second detection ring gauge, it proves that the stud meets the no-go gauge requirement. When the stud on the sealing plate can be screwed into the second detection ring gauge, it proves that the stud does not meet the no-go gauge requirement. The second detection sensor is used to detect the downward movement of the second lifting seat to determine whether the stud on the sealing plate is screwed into the second detection ring gauge. Overall, this improves the efficiency of no-go gauge detection, ensures the level of no-go gauge detection, and results in better product consistency.

[0023] 2. As the same sealing plate rotates with the transfer mechanism, multiple go gauge inspection mechanisms sequentially inspect the external threads of multiple studs on the same sealing plate using go gauges. Multiple no-go gauge inspection mechanisms sequentially inspect the external threads of multiple studs on the same sealing plate using no-go gauges, ensuring an orderly inspection process and guaranteeing both inspection efficiency and quality.

[0024] 3. A first linear actuator drives a first lifting seat downwards, thereby moving a first drive shaft, a first detection ring gauge, and a first rotary actuator downwards. Simultaneously, the first rotary actuator drives the first drive shaft to rotate, thereby rotating a first flexible coupling and a first detection ring gauge. When the stud on the sealing plate can be fully screwed into the first detection ring gauge, it proves that the stud meets the go-ahead gauge requirements. When the stud on the sealing plate cannot be fully screwed into the first detection ring gauge, it proves that the stud does not meet the go-ahead gauge requirements. A first detection sensor is used to detect the downward movement of the first lifting seat to determine whether the stud on the sealing plate is fully screwed into the first detection ring gauge.

The first drive assembly 124 is mounted on the frame 110 and connected to the rotary seat 121. It drives the rotary seat 121 to rotate, thereby moving multiple first carriers 122 and multiple sealing plates 200 to different positions. Overall, this effectively improves space utilization and ensures efficient position transfer. One of the seventh linear actuators 125 is located below the loading station of the rotary seat 121 and can be activated to open the first clamping assembly 123 on the first carrier 122 at the loading station, so that the loading mechanism 130 can transfer the sealing plate 200 onto the first carrier 122 at the loading station. Another seventh linear actuator 125 is located below one of the unloading stations of the rotary seat 121 and can be activated to open the first clamping assembly 123 on the first carrier 122 at the corresponding unloading station, so that one of the unloading mechanisms 140 can disengage the sealing plate 200 from the corresponding first carrier 122. Another seventh linear actuator 125 is located below another unloading station of the rotary seat 121 and is capable of actuating to drive the first clamping assembly 123 on the first carrier 122 at the corresponding unloading station to open, so that another unloading mechanism 140 can disengage the sealing plate 200 from the corresponding first carrier 122.

[0044] Preferably, the first drive assembly 124 includes a third rotary driver 1241 and a reduction gearbox 1242. The third rotary driver 1241 is fixed to the frame 110. The reduction gearbox 1242 is fixed to the frame 110, with its input shaft fixedly connected to the output end of the third rotary driver 1241 and its output shaft fixedly connected to the middle of the bottom end of the rotary base 121. The third rotary driver 1241 drives the rotary base 121 to rotate via the reduction gearbox 1242.

[0045] Preferably, the third rotary driver 1241 is a servo motor or a stepper motor, etc.

[0046] Preferably, each seventh linear actuator 125 is a cylinder, hydraulic cylinder, or electric actuator, etc.

[0047] Preferably, such as Figure 8 and Figure 9 As shown, each first clamping assembly 123 includes a pressure block 1231, two pressing blocks 1232, two first transmission rods 1233, a transmission block 1234, a transmission ball 1235, a second transmission rod 1236, two guide rods 1237, and two return springs 1238. The pressure block 1231 is fixed to the first carrier 122, with a clearance hole formed in the middle, and its top surface is used to support the sealing plate 200. The two pressing blocks 1232 are both disposed in the clearance hole, with one end rotatably connected to each other, and the other end respectively able to press against the inner wall of the pressure groove 220 of the sealing plate 200. The two first transmission rods 1233 are respectively inclined, with their top ends rotatably connected to the bottom ends of the two pressure blocks 1231 one-to-one. The transmission block 1234 is disposed below the pressure block 1231 and can move up and down. A transmission ball 1235 is mounted on a transmission block 1234 and is rotatably connected to the bottom ends of two first transmission rods 1233. The axis of the second transmission rod 1236 is vertically oriented, with its top end fixedly connected to the transmission ball 1235 and its bottom end capable of abutting against the output shaft of the seventh linear actuator 125. The axes of two guide rods 1237 are also vertically oriented, with their top ends fixedly connected to pressure blocks 1231 and their bottom ends forming anti-detachment blocks to prevent the transmission block 1234 from falling off the guide rod 1237. Two return springs 1238 are correspondingly sleeved on the guide rods 1237, with their top ends abutting against pressure blocks 1231 and their bottom ends abutting against transmission blocks 1234. The output of the seventh linear actuator 125 drives the second transmission rod 1236 to move upward, thereby moving the transmission ball 1235 and the transmission block 1234 upward. This, in turn, drives the two pressing blocks 1232 to rotate via the two first transmission rods 1233, causing the two pressing blocks 1232 to disengage from the inner wall of the pressure groove 220, thus releasing the restriction on the sealing plate 200. During this process, the two return springs 1238 are gradually compressed. When the output of the seventh linear actuator 125 disengages from the second transmission rod 1236, the force of the two return springs 1238 restoring their deformation drives the transmission block 1234, the transmission ball 1235, and the second transmission rod 1236 downward. This, in turn, drives the two pressing blocks 1232 to rotate via the two first transmission rods 1233, causing the two pressing blocks 1232 to press against the inner wall of the pressure groove 220 of the sealing plate 200, thus restricting the sealing plate 200 onto the first carrier 122.

[0048] Reference Figure 3 , Figure 10 , Figure 11 and Figure 12In one embodiment, the feeding mechanism 130 includes a second carrier 131, a second drive assembly 132, a third bracket 133, a first movable seat 134, a third drive assembly 135, a third linear actuator 136, a third lifting seat 137, a second clamping assembly 138, and a third detection sensor 139. The second carrier 131 is movably mounted on the frame 110 and has multiple bearing holes 1311 for bearing the sealing plate 200. The second drive assembly 132 is mounted on the frame 110 and connected to the second carrier 131, for driving the second carrier 131 to move. The third bracket 133 is mounted on the frame 110. The first movable seat 134 is movably mounted on the third bracket 133, and its direction of movement is perpendicular to the direction of movement of the second carrier 131. The third drive assembly 135 is mounted on the third bracket 133 and connected to the first movable seat 134, for driving the first movable seat 134 to move. The third linear actuator 136 is mounted on the first movable seat 134 and moves with the first movable seat 134. The third lifting seat 137 is connected to the output end of the third linear actuator 136. The third linear actuator 136 drives the third lifting seat 137 to move up and down. The second clamping assembly 138 is mounted on the third lifting seat 137 and moves with the third lifting seat 137, used to clamp or release the sealing plate 200. The third detection sensor 139 is mounted on the third lifting seat 137, used to detect whether the sealing plate 200 has disengaged from the second clamping assembly 138, and to detect whether the sealing plate 200 is present in the bearing hole 1311 on the second carrier 131.

[0049] The loading process and principle are as follows: Multiple sealing plates 200 are manually placed one by one into the bearing holes 1311 of the second carrier 131. Then, the second drive assembly 132 drives the second carrier 131 to move laterally, thereby moving the multiple sealing plates 200 laterally. When the second carrier 131 reaches one side of the rotating seat 121, the third linear actuator 136 drives the third lifting seat 137 to move downward, thereby moving the second clamping assembly 138 downward. Then, the second clamping assembly 138 actuates, clamping one of the sealing plates 200 on the second carrier 131. Then, the third linear actuator 136 drives the third lifting seat 137 to move upward, thereby moving the second clamping assembly 138 upward. Next, the third drive assembly 135 drives the first moving seat 134 to move longitudinally, thereby moving the third linear actuator 136, the third lifting seat 137, the second clamping assembly 138, and the sealing plate 200 longitudinally. When the sealing plate 200 reaches above the first carrier 122 at the loading station of the rotary seat 121, the third linear actuator 136 drives the third lifting seat 137 to move downward, thereby causing the second clamping assembly 138 to move downward. Then, the second clamping assembly 138 actuates, releasing the sealing plate 200 so that it reaches the top surface of the first carrier 122. Next, the third linear actuator 136 drives the third lifting seat 137 to move upward, thereby causing the second clamping assembly 138 to move upward. Overall, this effectively improves loading efficiency, thus helping to ensure testing efficiency.

[0050] Preferably, such as Figure 11 As shown, the second drive assembly 132 includes a drive wheel 1321, a driven wheel 1322, a transmission belt 1323, a fourth rotary driver 1324, and a follower seat 1325.

The follower seat 1325 is fixedly connected to the transmission belt 1323 and the bottom surface of the second carrier 131, respectively. The fourth rotary driver 1324 drives the drive wheel 1321 to rotate, thereby driving the transmission belt 1323 and the driven wheel 1322 to rotate, and driving the second carrier 131 to move through the follower seat 1325. The use of belt drive offers higher transmission efficiency compared to other transmission methods, ensuring efficient material feeding and thus improving the inspection cycle time.

[0051] Preferably, the bottom surface of the second carrier 131 is slidably connected to the top of the frame 110 through a slide groove and a slide rail, so that the second carrier 131 can move efficiently and smoothly.

[0054] Preferably, the third linear actuator 136 is a cylinder, hydraulic cylinder, or electric push rod, etc.

[0055] Preferably, the second clamping assembly 138 includes a plurality of pneumatic grippers. The plurality of pneumatic grippers correspond one-to-one with a plurality of studs 210 on the sealing plate 200, and are used to clamp or release the corresponding studs 210 to facilitate the position transfer of the sealing plate 200.

[0056] Preferably, the third detection sensor 139 is a diffuse photoelectric sensor, which does not require precise alignment of the beam, is relatively simple to install and debug, can detect target objects with various surface properties, has high sensitivity, and low cost.

[0057] Preferably, an extension platform is formed on one side of the frame 110 to facilitate the operator to place multiple sealing plates 200 on the second carrier 131.

[0058] Reference Figure 13 and Figure 14 In one embodiment, multiple unloading mechanisms 140 are arranged circumferentially along the transfer mechanism 120, each used to disengage the sealing plate 200 from the transfer mechanism 120. One unloading mechanism 140 is used as an unloading mechanism for qualified products, disengaging qualified sealing plates 200 from the transfer mechanism 120. Another unloading mechanism 140 is used as an unloading mechanism for unqualified products, disengaging unqualified sealing plates 200 from the transfer mechanism 120. Each unloading mechanism 140 includes a conveyor 141, a fourth support 142, a second movable seat 143, a fourth linear driver 144, a fifth linear driver 145, a fourth lifting seat 146, and a third clamping assembly 147. The conveyor 141 is mounted on the frame 110, with one end facing the rotating seat 121 of the transfer mechanism 120. The fourth support 142 is mounted on the end of the conveyor 141 near the transfer mechanism 120. The second movable seat 143 is movably mounted on the fourth support 142. A fourth linear actuator 144 is mounted on a fourth bracket 142, and its output end is connected to a second movable base 143 for driving the second movable base 143 to move. A fifth linear actuator 145 is mounted on the second movable base 143 and moves with it. A fourth lifting base 146 is connected to the output end of the fifth linear actuator 145. The fifth linear actuator 145 drives the fourth lifting base 146 to move up and down. A third clamping assembly 147 is mounted on the fourth lifting base 146 and moves with it for clamping or releasing the sealing plate 200.

[0059] The unloading process and principle are as follows: First, the fourth linear actuator 144 drives the second moving seat 143 to move, thereby driving the fifth linear actuator 145, the fourth lifting seat 146, and the third clamping assembly 147 to move. When the third clamping assembly 147 reaches above the first carrier 122 at the unloading station of the rotary seat 121, the fifth linear actuator 145 drives the fourth lifting seat 146 to move downward, thereby driving the third clamping assembly 147 to move downward. Then, the third clamping assembly 147 actuates, clamping the sealing plate 200 on the first carrier 122 at the unloading station. Next, the fifth linear actuator 145 drives the fourth lifting seat 146 to move upward, thereby driving the third clamping assembly 147 and the sealing plate 200 to move upward. Then, the fourth linear actuator 144 drives the second moving seat 143 to move, thereby driving the fifth linear actuator 145, the fourth lifting seat 146, the third clamping assembly 147, and the sealing plate 200 to move. When the sealing plate 200 reaches directly above the conveyor 141, the third clamping assembly 147 releases the sealing plate 200, causing it to fall onto the conveyor 141, where it is then transported. Overall, this effectively improves the material feeding efficiency, thereby helping to ensure the testing cycle time.

[0060] Preferably, each feeding mechanism 140 further includes an isolation cover 148. The isolation cover 148 is positioned above the conveyor 141 and serves as an isolation device.

[0061] Preferably, the fourth linear actuator 144 and the fifth linear actuator 145 are cylinders, hydraulic cylinders, or electric push rods, etc.

[0062] Preferably, the third clamping assembly 147 includes a plurality of pneumatic grippers. The plurality of pneumatic grippers correspond one-to-one with a plurality of studs 210 on the sealing plate 200, and are used to clamp or release the corresponding studs 210 to facilitate the position transfer of the sealing plate 200.

[0063] Reference Figure 13 In one embodiment, the automotive power steering plate inspection device further includes a marking mechanism 170 and multiple storage mechanisms 180. The marking mechanism 170 is mounted on the frame 110 and located between two of the unloading mechanisms 140, and can mark the studs 210 on the plate 200 of the moving mechanism. Before defective products leave the transfer mechanism 120, the marking mechanism 170 can replace manual marking of the defective studs 210 on the plate 200, facilitating subsequent tracing of the cause of the defect. The multiple storage mechanisms 180 are arranged one-to-one with the multiple unloading mechanisms 140 below the end of the conveyor 141 away from the transfer mechanism 120, and are used to store qualified / defective products respectively.

[0064] Reference Figure 13 and Figure 15In one embodiment, the marking mechanism 170 includes a fifth support 171, a plurality of sixth linear actuators 172, a plurality of fifth lifting seats 173, and a plurality of marking pens 174. The fifth support 171 is mounted on the frame 110 and provides support. The plurality of sixth linear actuators 172 are respectively mounted on the fifth support 171. The plurality of fifth lifting seats 173 are fixedly connected to the output ends of the plurality of sixth linear actuators 172 in a one-to-one correspondence. The plurality of marking pens 174 are mounted on the fifth lifting seats 173 in a one-to-one correspondence. When one or more studs 210 on the same sealing plate 200 are detected to be defective, the sixth linear actuator 172 drives the corresponding fifth lifting seat 173 to move downwards, thereby causing the corresponding marking pen 174 to move downwards to mark the corresponding defective stud 210. This replaces manual marking of defective studs 210 on the sealing plate 200, improving marking efficiency.

[0065] Preferably, each sixth linear actuator 172 is a cylinder, hydraulic cylinder, or electric actuator, etc.

[0066] Reference Figure 13 and Figure 16 In one embodiment, each storage mechanism 180 includes a third carrier 181 and a storage bin 182. The storage bin 182 is mounted on the third carrier 181 and is used to store qualified / unqualified products. The third carrier 181 is movable to move the storage bin 182, facilitating the relocation of each storage mechanism 180.

[0067] The implementation principle of this embodiment is as follows: The frame 110 provides support. The transfer mechanism 120 is used to move the sealing plate 200. The feeding mechanism 130 supplies the sealing plate 200 to be inspected to the transfer mechanism 120. The unloading mechanism 140 removes the inspected sealing plate 200 from the transfer mechanism 120. The go gauge inspection mechanism 150 performs go gauge inspection on the external thread of the stud 210 of the sealing plate 200 located on the transfer mechanism 120. The no-go gauge inspection mechanism 160 performs no-go gauge inspection on the external thread of the stud 210 of the sealing plate 200 located on the transfer mechanism 120. In this way, the go and no-go gauge inspection of the external thread of the stud 210 on the sealing plate 200 can be replaced or assisted by manual inspection, effectively improving inspection efficiency, ensuring inspection level, and resulting in better product consistency.

[0068] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
