Description

Technical Field

[0001] The present application relates to the technical field of component detection, and in particular to a stainless steel composite plate detection device. Background Art

[0002] Stainless steel composite plates are commonly used components in the fields of automobiles, construction, etc. During production, stainless steel composite plates need to be tested for strength using stainless steel composite plate testing equipment.

[0003] Existing stainless steel composite plate testing devices generally include a frame, a clamping frame, a pressure plate device and a curvature measuring instrument. The clamping frame and the pressure plate device are fixedly connected to the frame. The user can clamp one end of the plate to be tested with the clamping frame, and then apply a certain pressure to the other end of the plate through the pressure plate device. Finally, the yield strength of the plate is measured by the curvature measuring instrument, and whether the plate is a qualified product is determined based on the test results.

[0004] However, since the distance between the pressure plate device and the clamping frame is fixed, the pressure plate device has a single force application point on the plate, so that the curvature measuring instrument can only detect the bending strength at the center of the plate, while the yield strength of the rest of the plate cannot be detected well, resulting in a blind spot in the detection of the stainless steel composite plate detection device.

[0005] In view of this, it is necessary to provide a stainless steel composite plate detection device. Summary of the invention

[0006] In order to solve the problem that the existing stainless steel composite plate detection device can only detect the bending strength at the center of the plate and has a blind spot in the detection, the present application provides a stainless steel composite plate detection device.

[0007] The present application provides a stainless steel composite plate detection device, which adopts the following technical solution: comprising a frame and a fixing plate assembly, a pressing plate assembly and a detection assembly arranged on the frame, wherein the fixing plate assembly is provided with a receiving channel for inserting the plate; The pressing plate assembly includes a pressing plate unit and a driving unit, wherein the pressing plate unit is slidably connected to the frame and can apply force to a side of the plate surface away from the accommodating channel, and the driving unit is transmission-connected to the pressing plate unit and can drive the pressing plate unit to move along the passage direction of the accommodating channel, and when the pressing plate unit approaches the accommodating channel, the pressing plate unit can abut against and push the plate to move along the accommodating channel; The detection assembly is capable of detecting the bending strength of a portion of the plate material located between the accommodating channel and the pressure plate unit.

[0008] By adopting the above technical solution, the user can first insert one end of the plate to be tested into the accommodating channel, and then start the driving unit to drive the pressure plate unit to move to a position abutting the other end of the plate, and then start the pressure plate unit to apply upward or downward pressure to the side of the plate surface away from the accommodating channel, so that the part of the plate located at the port on one side of the accommodating channel close to the pressure plate unit is bent under force, so that the user can detect the bending strength of the part through the detection component; after the detection, the user can first start the driving unit to drive the pressure plate unit to push the plate to move a distance along the accommodating channel, and then start the pressure plate unit and the detection unit to continue to detect the part of the plate that is now located on the port on one side of the accommodating channel close to the pressure plate unit. By repeating this step, the user can complete the detection of various parts of the plate to be tested, which is convenient for the user to fully understand the bending performance of various parts of the stainless steel composite plate, and there will be no blind spots in detection.

[0009] Specifically, the pressure plate units are provided on both sides of the accommodating channel, the two pressure plate units correspond one-to-one to the two ports of the accommodating channel, and the two pressure plate units are both transmission-connected to the driving unit, and the driving unit can drive any one of the two pressure plate units to approach the corresponding port on the accommodating channel and push the plate so that the plate passes through the accommodating channel and approaches the other of the two pressure plate units.

[0010] By adopting the above technical solution, after inserting one end of the plate to be inspected into the accommodating channel, the user can first use one of the two pressure plate units adjacent to the other end of the plate to cooperate with the detection component to detect the part of the plate extending out of the accommodating channel; after the detection of this part is completed, the part of the plate originally located outside the accommodating channel will be pushed into the accommodating channel, and the part of the plate originally located in the accommodating channel will extend out of the accommodating channel and approach another unused pressure plate unit, so that the user can detect the remaining, undetected part of the plate by cooperating with the pressure plate unit and the detection component, so that the user can complete the detection of each part of the plate to be inspected, ensuring that there is no detection blind spot.

[0011] Furthermore, the pressure plate unit includes a sliding frame and an abutment plate, a telescopic cylinder and a crimping piece arranged on the sliding frame. A sliding groove is opened on the frame along the passing direction of the accommodating channel. The sliding frame can be slidably arranged in the sliding groove. The abutment plate can abut against the plate placed in the accommodating channel. The crimping piece is arranged between the abutment plate and the accommodating channel. The telescopic cylinder is transmission-connected to the crimping piece and can drive the crimping piece to approach and abut against the plate.

[0012] By adopting the above technical solution, the telescopic cylinder can drive the crimping piece to abut against the plate and apply upward or downward pressure to the plate; the abutting plate can abut against the end of the plate and push the plate to move.

[0013] Furthermore, the pressure plate unit includes two telescopic cylinders, which are arranged opposite to each other up and down. A crimping piece is provided on the piston rod of each telescopic cylinder, and a pressure plate gap is formed between the two crimping pieces. One end of the plate can pass through the pressure plate gap and abut against the abutment piece.

[0014] By adopting the above technical solution, the user can use two telescopic cylinders to alternately apply upward and downward pressure to the plate, so that the plate forms a wave-like deformation after multiple bending measurements, and then the end of the plate pressed by the pressure plate unit will not be unable to pass through the accommodating channel smoothly due to a large deformation upward or downward relative to the other end of the plate.

[0015] Furthermore, the abutment member is an abutment roller, and the roller surface of the abutment roller can abut against the plate surface of the plate.

[0016] By adopting the above technical solution, the design of the abutting roller makes the abutment between the crimping unit and the plate surface smaller, so that the user can measure the distance between the force point of the plate and the port of the accommodating channel.

[0017] Further, the fixing plate assembly includes two fixing rod groups and a plurality of limiting roller groups arranged between the two fixing rod groups, each fixing rod group includes two fixing rods arranged opposite to each other up and down, and a fixed gap is formed between the two fixing rods, and each fixing rod is arranged in a horizontal direction and fixedly connected to the frame; Each limiting roller group includes a first limiting roller, a second limiting roller and a limiting member. The first limiting roller and the second limiting roller are arranged opposite to each other up and down and a limiting gap is formed between the roller surfaces of the two. The rotating shafts of the first limiting roller and the second limiting roller can be slidably connected to the frame in a vertical direction. The limiting member is transmission-connected to the first limiting roller and the second limiting roller and can fix the distance between the first limiting roller and the second limiting roller unchanged. The two fixed gaps and each limiting gap are combined to form the accommodating channel.

[0018] By adopting the above technical solution, when the part of the plate with wavy deformation due to multiple bending measurements passes through the fixed gap, each limiting roller group will move up or down along the surface of the plate, so that the accommodating channel can spontaneously adapt to the shape of the plate to ensure that the inner wall of the accommodating channel can fully fit the plate, thereby facilitating the plate to be inspected by the second crimping unit.

[0019] Further, the limiting member includes a first piston rod and a second piston rod, a first buffer chamber and a second buffer chamber are provided inside the frame, and a limiting groove is provided on the frame in a vertical direction, one end of the rotating shaft of the first limiting roller extends into the limiting groove, a first connecting hole leading to the first buffer chamber is provided on the top wall of the limiting groove, a piston end of the first piston rod is provided in the first buffer chamber and divides the first buffer chamber into a first rod chamber and a first rodless chamber, and a rod body of the first piston rod extends into the limiting groove through the first connecting hole and is connected to the rotating shaft of the first limiting roller; One end of the rotating shaft of the second limiting roller extends into the limiting groove, a second connecting hole leading to the second buffer chamber is opened on the bottom wall of the limiting groove, the piston end of the second piston rod is arranged in the second buffer chamber and divides the second buffer chamber into a second rod chamber and a second rodless chamber, the rod body of the second piston rod passes through the second connecting hole and extends into the limiting groove and is connected to the rotating shaft of the second limiting roller; A liquid through hole leading to the second rodless chamber is formed on the inner wall of the first rodless chamber, and the first rodless chamber, the second rodless chamber and the liquid through hole are all filled with a pressure transmission medium.

[0020] By adopting the above-mentioned technical scheme, when the first limiting roller moves upward along the wavy plate, it will drive the first piston rod to move upward, and then the first piston rod will squeeze the pressure-transmitting medium in the first rodless chamber and drive the second piston rod and the second limiting roller to move upward synchronously, so that the limiting gap between the first limiting roller and the second limiting roller remains unchanged; when the second limiting roller moves downward along the wavy plate, it will drive the second piston rod to move downward, and then the second piston rod will squeeze the pressure-transmitting medium in the second rodless chamber and drive the first piston rod and the first limiting roller to move upward synchronously, so that the limiting gap between the first limiting roller and the second limiting roller remains unchanged.

[0021] Furthermore, the limiter also includes a first elastic member and a second elastic member, wherein the first elastic member is disposed in the first rodless chamber and can apply an upward force to the first piston rod; The second elastic member is disposed in the second rodless chamber and is capable of applying an upward force to the second piston rod.

[0022] By adopting the above technical solution, the first elastic member can cooperate with the second elastic member to apply an upward force to the first piston rod and the second piston rod and the first limiting roller and the second limiting roller, so that the elastic force of the elastic member can be used to offset the self-weight of the first piston rod and the second piston rod and the first limiting roller and the second limiting roller, making it convenient for the first limiting roller and the second limiting roller to slide up and down along the wavy part of the plate.

[0023] Furthermore, each of the first limiting rollers and the second limiting rollers has a roller surface wrapped with a buffer member, and the buffer member can abut against the plate surface of the plate.

[0024] By adopting the above technical solution, the buffer member can form a buffer between the roller surfaces of the first limiting roller and the second limiting roller and the plate, thereby protecting the plate surface so that the plate is not easily crushed.

[0025] Furthermore, the detection component includes a slide rail and a curvature measuring instrument. The slide rail is arranged on the frame along the passage direction of the accommodating channel. The curvature measuring instrument is arranged on the slide rail and can slide back and forth along the slide rail between two ports of the accommodating channel.

[0026] By adopting the above technical solution, the user can measure the curvature of the plate at the port by sliding the curvature measuring instrument along the slide rail to the port of the accommodating channel.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. It comprises a frame and a fixing plate assembly, a pressing plate assembly and a detection assembly arranged on the frame, wherein the fixing plate assembly is provided with a receiving channel for inserting a plate; the pressing plate assembly comprises a pressing plate unit and a driving unit, wherein the pressing plate unit is slidably connected to the frame and can apply force to a side of the plate surface away from the receiving channel, the driving unit is transmission-connected to the pressing plate unit and can drive the pressing plate unit to move along the passing direction of the receiving channel, and when the pressing plate unit approaches the receiving channel, the pressing plate unit can abut against and push the plate to move along the receiving channel; the detection assembly can detect the bending strength of the portion of the plate located between the receiving channel and the pressing plate unit, so that the user can first insert one end of the plate to be detected into the receiving channel, and then start the driving unit to drive the pressing plate unit to move to abut against the other end of the plate. The pressure plate unit is then started to apply upward or downward pressure to the side of the plate surface away from the accommodating channel, so that the portion of the plate located on the accommodating channel near the port on one side of the pressure plate unit is bent under force, so that the user can detect the bending strength of the portion through the detection component; after the detection, the user can first start the driving unit to drive the pressure plate unit to push the plate to move a distance along the accommodating channel, and then start the pressure plate unit and the detection unit to continue to detect the portion of the plate that is now located on the accommodating channel near the port on one side of the pressure plate unit. By repeating this step, the user can complete the detection of various parts of the plate to be detected, which is convenient for the user to fully understand the bending performance of various parts of the stainless steel composite plate, and there will be no detection blind spots; 2. A pressure plate unit is provided on both sides of the accommodating channel, and the two pressure plate units correspond to the two ports of the accommodating channel one by one, and the two pressure plate units are both connected to the driving unit in transmission.

The curvature measuring instrument 42 is arranged on the slide rail 41 and can slide back and forth between the two ports of the accommodating channel along the slide rail 41.

[0036] The use process of the stainless steel composite plate detection device described in this application is as follows: S1. The user can first insert one end of the plate 5 to be tested into the accommodating channel, and ensure that the length of the portion of the plate 5 exposed outside the accommodating channel is not less than the difference between the overall length of the plate 5 and the length of the accommodating channel, and then start the driving cylinder 321 corresponding to the end of the plate 5 outside the accommodating channel, so as to drive the sliding frame 311 connected thereto to approach the plate 5 through the driving cylinder 321, until the abutting plate 312 on the sliding frame 311 abuts against the end of the plate 5, and then slide the curvature measuring instrument 42 along the slide rail 41 to the position corresponding to the port on the accommodating channel where the plate 5 extends out; S2, first start the two telescopic cylinders 313 on the sliding frame 311 abutting against the plate 5 and located on the same side of the plate 5, so that the two telescopic cylinders 313 drive the abutting rollers 314 connected to them to apply upward or downward pressure to the plate 5, and then make the part of the plate 5 located at the end of the accommodating channel abut against the fixed rod 21 and bend under force, so that the curvature measuring instrument 42 can measure the degree of curvature of the part, and then start the previously started driving cylinder 321 to drive the sliding frame 311 to approach the accommodating channel for a distance, so that the length of the part of the plate 5 exposed outside the accommodating channel is reduced by the same distance, and then start the two telescopic cylinders 313 on the other side of the plate 5 on the sliding frame 311 abutting against the plate 5, so that the two telescopic cylinders 313 drive the abutting rollers 314 connected to them to apply a pressure opposite to the pressure previously applied to the plate 5, and measure the degree of curvature of the part of the plate 5 located at the end of the accommodating channel through the curvature measuring instrument 42; S3, repeat S2 until the end of the plate 5 originally exposed outside the accommodating channel is completely inside the accommodating channel, and the portion of the plate 5 originally inside the accommodating channel extends out of the accommodating channel and approaches another unused platen frame, and then the curvature measuring instrument 42 is slid along the slide rail 41 to the position corresponding to the end of the accommodating channel from which the plate 5 extends; S4, repeat S2, and use the unused platen frame, telescopic cylinder 313 and driving cylinder 321 in the old S2 step to complete the process until the end of the plate 5 originally exposed outside the accommodating channel completely enters the accommodating channel.

[0037] Preferably, a buffer member (not shown in the figure) can be wrapped on the roller surface of the first limiting roller 22 and the second limiting roller 24. The buffer member can be rubber, so that a buffer can be formed between the roller surface of the first limiting roller 22 and the second limiting roller 24 and the plate 5 through the rubber, and then the plate surface of the plate 5 is protected to prevent the plate 5 from being easily crushed.

[0038] The implementation principle of the stainless steel composite plate detection device described in this application is: After inserting one end of the plate 5 to be inspected into the accommodating channel, the user can first use one of the two pressure plate units 31 adjacent to the other end of the plate 5 to cooperate with the detection component 4 to inspect the portion of the plate 5 extending out of the accommodating channel; after the inspection of this portion is completed, the portion of the plate 5 originally located outside the accommodating channel will be pushed into the accommodating channel, and the portion of the plate 5 originally located in the accommodating channel will extend out of the accommodating channel and approach another unused pressure plate unit 31, so that the user can inspect the remaining, uninspected portion of the plate 5 by cooperating with the pressure plate unit 31 and the detection component 4, so that the user can complete the inspection of various portions of the plate 5 to be inspected, which is convenient for the user to fully understand the bending performance of various portions of the stainless steel composite plate 5, and there will be no blind spots in the inspection; When the plate 5 is pressed, the telescopic cylinders 313 on both sides of the plate 5 are alternately used to make the plate 5 form a wave-like deformation after being pressed and bent for multiple times, so that the end of the plate 5 pressed by the pressing plate unit 31 will not be unable to pass through the accommodating channel smoothly due to a large deformation upward or downward relative to the other end of the plate 5; When the portion of the plate 5 that has been deformed in a wavy shape due to multiple bending measurements passes through the fixed gap, when the first limiting roller 22 moves upward along the wavy plate 5, it drives the first piston rod 231 to move upward, and then the first piston rod 231 squeezes the pressure-transmitting medium in the first rodless chamber and drives the second piston rod 232 and the second limiting roller 24 to move upward synchronously, so that the limiting gap between the first limiting roller 22 and the second limiting roller 24 remains unchanged; when the second limiting roller 24 moves downward along the wavy plate 5, it drives the second piston rod 2 32 moves downward, thereby causing the second piston rod 232 to squeeze the pressure-transmitting medium in the second rodless chamber and drive the first piston rod 231 and the first limiting roller 22 to move upward synchronously, so that the limiting gap between the first limiting roller 22 and the second limiting roller 24 remains unchanged, so that each limiting roller group will move up or down along the surface of the plate 5, and then the accommodating channel can spontaneously adapt to the shape of the plate 5, so as to ensure that the inner wall of the accommodating channel can be completely fitted with the plate 5, so that the plate 5 can be easily inspected by the second crimping unit.
