Description

Technical Field

[0001] This application relates to the technical field of metal plating detection, and in particular to a device for detecting the wear resistance of the coating of a metal plating. Background Art

[0002] Since wear is a common phenomenon in the industrial field and daily life, and the main reasons for this phenomenon are physical, mainly including particle wear, adhesive wear, fatigue wear and corrosive wear, which is an important cause of energy loss. In mechanical equipment, in order to improve the wear resistance of components, electroplating is often carried out on the surface of metal components, and after electroplating, it is often necessary to detect the wear resistance of the metal plating.

[0003] Common wear resistance detection devices include a vertically arranged frame and a standard part that is arranged on the frame in a lifting and rotating manner. The frame is provided with a lifting part for driving the standard part to lift and a power source for driving rotation. The frame is also provided with a mounting disk, and the mounting disk is internally provided with a cavity for storing and fixing the sample to be detected, and a torque sensor is arranged on the standard part.

[0004] In view of the above related technologies, when performing wear resistance detection, first, technicians cut the plating to be detected into the size of a standard test block and place the plating to be detected on the mounting disk. Then, the power source is used to lower the standard part to a position where it is in contact with the surface of the plating to be detected. The power source drives the standard part to rotate, so that the standard part is in contact with the surface of the plating to be detected and rotates along the rotation direction perpendicular to the contact surface. Then, relevant technicians calculate the wear resistance of the metal plating through the initial reading of the torque sensor and the reading when the plating to be detected rotates. However, in actual situations, there are two forms of sliding wear and rolling wear during the use of metal plating. The above-mentioned equipment can only perform single wear detection, and the obtained wear resistance of the metal plating is inaccurate. Moreover, at least two sets of equipment are required for sliding wear and rolling wear detection, which increases the detection cost and reduces the detection efficiency. Summary of the Invention

[0005] In order to facilitate the simultaneous detection of sliding wear and rolling wear of metal plating, reduce the detection cost and improve the detection efficiency at the same time, this application provides a device for detecting the wear resistance of the coating of a metal plating.

[0006] A device for detecting the wear resistance of the coating of a metal plating provided by this application adopts the following technical solutions: A metal-plated part coating wear resistance detection device, including a frame and a sliding wear detection component and a rolling wear detection component which are arranged on the frame in a lifting manner. There are also two groups of clamping blocks arranged oppositely on the frame. The two groups of clamping blocks are arranged oppositely, and clamping grooves are formed on the clamping blocks. The plated part is movably clamped in the clamping grooves, and the two groups of clamping blocks movably clamp the plated part; The sliding wear detection component includes a first mounting rod which is lifted and rotated on the frame and a sliding detection roller which is rotated on the mounting rod. The end side of the sliding detection roller is attached to the surface of the plated part. The rotation axis of the sliding detection roller is consistent with the height direction of the frame. A torque sensor is arranged on the sliding detection roller, and a first rotation motor for driving the first mounting rod to rotate is arranged on the frame; The rolling wear detection component includes a second mounting rod which is lifted and rotated on the frame and a rolling detection roller which is rotated on the second mounting rod. The circumferential surface of the rolling detection roller is movably attached to the surface of the plated part. The rotation axis of the rolling detection roller is perpendicular to the height direction of the frame. A torque sensor is also arranged on the rolling detection roller, and a second rotation motor for driving the second mounting rod to rotate is arranged on the frame; The first mounting rod and the second mounting rod are arranged oppositely, and a switching component for lifting and adjusting the first mounting rod and the second mounting rod according to the detection requirements of the plated part is also arranged on the frame; When it is necessary to perform sliding wear detection and rolling wear detection simultaneously, the switching component drives the first mounting rod and the second mounting rod to approach synchronously so that the sliding detection roller is attached to the surface of the plated part and the rolling detection roller is attached to the other surface of the plated part for detection; When it is necessary to perform sliding wear detection / sliding molding detection, the switching component drives the first mounting rod and the second mounting rod to approach synchronously so that the sliding detection roller is attached to the surface of the plated part and the rolling detection roller is attached to the other surface of the plated part for alternative detection.

[0007] By adopting the above technical scheme, when detecting the wear resistance of the plated part, first, the technician places the plated part to be detected into the clamping grooves of the two clamping blocks, clamps the plated part through the two clamping blocks, and then controls the lifting of the sliding wear detection component or the rolling wear detection component to detect the wear of the surface of the plated part.

[0008] Since conventional metal plating parts are used as instrument housings or connecting components, when used as instrument housings, they are often subject to more rolling wear; when used as connecting components, they are subject to more sliding wear; and at the connecting components of some precision instruments, cooling oil or lubricating oil is often required for cooling or lubrication, and the presence of cooling oil and lubricating oil will cause both rolling wear and sliding wear on the connecting components. Therefore, for different usage conditions and scenarios, it is necessary to detect sliding wear and rolling wear.

[0009] It should be noted here that first, standard parts (two types with and without plating) need to be placed in the clamping grooves of the clamping blocks. By judging the standard readings based on the readings of the torque sensors on the sliding detection roller and the rolling detection roller, the readings of the plated and non-plated parts in the standard state can be obtained. Thus, during the test, the wear resistance of the plating part can be judged according to the readings of the torque sensors and the number of turns of the sliding detection roller / rolling detection roller.

[0010] When detecting the wear resistance of the plating part, it is necessary to select according to its actual usage scenario, and detect the sliding wear and rolling wear on the same surface or detect the sliding wear and rolling wear on two surfaces respectively.

[0011] When detecting the rolling wear on one surface of the plating part and the sliding wear on the other surface, at this time, the switching part is used to make the first mounting rod and the second mounting rod approach each other, so that the sliding detection roller is in contact with the surface of the plating part, and the rolling detection roller is in contact with the other surface of the plating part. The sliding detection roller and the rolling detection roller rotate simultaneously. By reading the readings of the torque sensors on the sliding detection roller and the rolling detection roller and corresponding the number of turns of the sliding detection roller and the rolling detection roller, the wear resistance of the plating part can be obtained.

[0012] At the same time, in some actual application scenarios, the plating part will have both sliding wear and rolling wear. Therefore, it is necessary to judge the wear resistance of the plating part in such an application scenario. When detecting the sliding wear and rolling wear of the plating part, at this time, the switching part drives the first mounting rod and the second mounting rod to rise or fall synchronously. When the first mounting rod and the second mounting rod fall synchronously, at this time, the sliding friction roller is in contact with the surface of the plating part, so as to realize the sliding friction detection. When the first mounting rod and the second mounting rod rise synchronously, at this time, the clamping block drives the plating part to flip until the rolling friction roller is in contact with the surface of the plating part, realizing the detection of the same surface of the plating part. By alternately performing such detection methods in turn, the wear resistance of the plating part in the actual application scenario can be simulated.

[0013] Optionally, the switching member includes a first sliding rack connected to the first mounting rod, a second sliding rack connected to the second mounting rod, and a sliding gear that meshes with the first sliding rack and the second sliding rack movably. The first sliding rack and the second sliding rack are respectively located on opposite sides of the sliding gear.

[0014] By adopting the above technical solution, when it is necessary to detect both sides of the plated part simultaneously, at this time, the sliding gear meshes with both the first sliding rack and the second sliding rack. When the rolling friction roller descends, it drives the first sliding rack to descend. At this time, the first sliding rack drives the meshing sliding gear to rotate, thereby driving the second sliding rack to rise, and then driving the sliding friction roller to fit against the bottom side of the plated part, so as to detect the wear resistance of both sides of the plated part simultaneously and improve the wear resistance detection efficiency of the plated part.

[0015] And when only single-sided rolling wear detection or single-sided sliding wear detection is required, by arranging the rolling detection roller and the sliding wear detection roller relatively, when performing single-sided rolling wear detection, the sliding detection roller provides continuous pressing against the plated part. When performing single-sided sliding wear detection, the rolling detection roller also provides continuous pressing against the plated part, thereby improving the accuracy of single-sided rolling wear detection and sliding wear detection separately and reducing the problem of wear resistance detection accuracy caused by the deformation of the plated part.

[0016] Optionally, the switching member further includes a first adjusting rack connected to the first mounting rod and a second adjusting rack connected to the second mounting rod. The clamping block is rotatably arranged on the frame. An adjusting gear is provided at the rotating shaft of the clamping block. The adjusting gear meshes with the first adjusting rack and the second adjusting rack movably. The first adjusting rack and the second adjusting rack move up and down synchronously. The frame is further provided with an adjusting member for selectively moving up and down the first adjusting rack and the first sliding rack.

[0017] By adopting the above technical solution, when it is necessary to perform rolling wear detection and sliding wear detection on the same side of the plated part, at this time, the adjusting gear meshes with both the first adjusting rack and the second adjusting rack. When the first mounting rod descends, the first adjusting rack descends driven by the first mounting rod. The first adjusting rack and the second adjusting rack descend synchronously, so that when the sliding detection roller fits against the surface of the plated part, the rolling detection roller separates from the surface of the plated part.

[0018] After the sliding wear detection is completed, when the first adjusting rack and the second adjusting rack rise synchronously, at this time, the sliding detection roller separates from the surface of the plated part, and the rolling detection roller fits against the surface of the plated part.

[0019] And by setting the adjusting member, the adjusting gear meshes with the first adjusting rack and the second adjusting rack, and the sliding gear meshes with the first sliding rack and the second sliding rack alternatively, so as to realize the switching between sliding wear detection and rolling wear detection.

[0020] Optionally, the adjusting member includes a connecting shaft slidably arranged on the frame. The adjusting gear and the sliding gear are both arranged on the connecting shaft. A connecting block is further arranged on the connecting shaft. A clamping groove is formed on the connecting block. One ends of the first adjusting rack and the second adjusting rack close to each other are both movably clamped with the clamping groove. When the connecting shaft slides to make the adjusting gear mesh with the first adjusting rack, the connecting block is clamped with both the first adjusting rack and the second adjusting rack.

[0021] By adopting the above technical solution, when it is necessary to adjust to detect the rolling wear and sliding wear on the same surface of the plating part, at this time, the technician pulls the connecting shaft to drive the adjusting gear and the sliding gear to slide, so that the sliding gear is separated from the first sliding rack and the second sliding rack. At this time, the connecting block arranged on the connecting shaft is clamped with the first adjusting rack and the second adjusting rack, so as to realize the connection between the first adjusting rack and the second adjusting rack, and at the same time realize the meshing of the adjusting gear with the first adjusting rack and the second adjusting rack, and further realize the synchronous lifting of the sliding detection roller and the rolling detection roller, and further realize the wear resistance detection on the same surface of the plating part.

[0022] Optionally, coating holes are formed on the inner side walls of the clamping grooves of the clamping blocks. A plurality of coating holes are formed, and the plurality of coating holes are all arranged towards the center of the surface of the plating part. A liquid storage tank communicated with the coating holes is arranged on the frame. An environmental liquid simulating the use working condition of the plating part is stored in the liquid storage tank. When the clamping block is turned over, an extruding member for making the environmental liquid flow out of the coating holes is further arranged on the frame.

[0023] By adopting the above technical solution, since when the plating part is used as a connecting component, the problems of rolling wear and sliding wear often occur under the action of lubricating oil or cooling oil. Therefore, when detecting the rolling wear and sliding wear on the same surface, in order to more accurately obtain the wear resistance of the plating part, at this time, when the clamping block is turned over, the liquid storage tank is set to spray the environmental liquid on the surface of the plating part through a plurality of coating holes, so as to more accurately simulate the use working condition during the rolling wear detection, and thus obtain the wear resistance of the plating part when it is used under the working condition of a connecting part.

[0024] Optionally, the clamping block is hollowly arranged, and the cavity inside the clamping block is communicated with the liquid storage tank. The extrusion member includes a sliding plate slidably arranged inside the clamping block. An adjusting screw rod is arranged on the frame, and the adjusting screw rod is threadedly matched with the sliding plate. A flow hole is formed in the sliding plate, and a first blocking plate is rotatably arranged at the coating hole, and a second blocking plate is arranged at the flow hole; when the sliding plate slides towards the coating hole, the first blocking plate opens the coating hole, and the second blocking plate closes the flow hole; When the sliding plate slides away from the coating hole, the second blocking plate opens the flow hole, and the first blocking plate closes the coating hole.

[0025] By adopting the above technical solution, when performing sliding wear detection and rolling wear detection on the same surface of the plating part, at this time, during the flipping process of the clamping block, the clamping block drives the sliding plate to rotate. Since the adjusting screw rod is arranged on the frame, the sliding plate slides inside the clamping block under the action of the screw rod. During the sliding process of the sliding plate, the first blocking plate and the second blocking plate rotate respectively. During the rising process of the sliding detection roller, at this time, the clamping block rotates, and the sliding plate slides towards the coating hole, so as to squeeze the environmental liquid inside the clamping block out of the coating hole. During the descending process of the sliding detection roller, at this time, the clamping block rotates, and the sliding plate slides away from the coating hole, so as to squeeze the environmental liquid in the liquid storage tank into the clamping block for the next extrusion.

[0026] Optionally, a connecting block is further arranged on the frame. The connecting block is hollowly arranged, and the connecting block is movably communicated with the liquid storage tank and the clamping block. An opening and closing member is arranged on the connecting block; When the sliding detection roller and the rolling detection roller move towards each other, the opening and closing member blocks the connecting block; When the sliding detection roller and the rolling detection roller move in the same direction, the opening and closing member opens the connecting block.

[0027] By adopting the above technical solution, since during single detection, that is, when it is not necessary to perform sliding wear and rolling wear detection simultaneously, if the lubrication of the environmental liquid is added, it will instead affect the accuracy of the detection result. Therefore, the connecting hole is movably blocked by the arranged opening and closing member. During single detection, the clamping block is not communicated with the liquid storage tank, so as to reduce the leakage of the environmental liquid, save resources and improve the accuracy of the detection result at the same time.

[0028] Optionally, the opening and closing member includes a sliding block connected to the connecting shaft. An opening and closing block is also elastically slidably arranged on the connecting block. The sliding block is movably attached and pressed against the opening and closing block, and the side of the opening and closing block away from the sliding block is movably attached and pressed against the inner wall of the connecting block.

[0029] By adopting the above technical solution, when the technician needs to switch the detection state, the technician pulls the connecting shaft at this time, thereby driving the sliding block to slide. The sliding block abuts against the opening and closing block and slides, so that the opening and closing block seals or opens the inner cavity of the communicating pipe, thereby realizing the connection and sealing between the liquid storage tank and the clamping block, and thus improving the accuracy of the detection result according to the difference in the detection state.

[0030] Optionally, a first rotating motor is provided on the sliding detection roller, a second rotating motor is provided on the rolling detection roller, a controller is provided on the frame, the first rotating motor and the second rotating motor are both electrically connected to the controller, and the controller controls the rotation periods of the first rotating motor and the second rotating motor.

[0031] By adopting the above technical solution, after the theoretical values of the rolling wear and sliding wear ratios of the plating part under the use condition are judged according to the actual situation, the controller controls the rotation periods of the first rotating motor and the second rotating motor, so as to adjust different sliding wear detection and rolling wear detection periods according to the actual situation.

[0032] In summary, the present application includes at least one of the following beneficial technical effects: 1. By arranging the sliding wear detection assembly, the rolling wear detection assembly and the switching member arranged oppositely, with one device, the sliding wear and rolling wear of the plating part can be detected simultaneously, and the sliding wear detection and rolling wear detection of the same surface of the plating part can be carried out to judge the wear resistance of the plating part; 2. By arranging the sliding gear, the first sliding rack, the second sliding rack, the adjusting gear, the first adjusting rack and the second adjusting rack, when it is necessary to synchronously carry out the sliding wear detection and rolling wear detection on different surfaces of the plating part, the sliding gear meshes with the first sliding rack and the second sliding rack, and when it is necessary to carry out the sliding wear detection and rolling wear detection on the same surface of the plating part, the adjusting gear meshes with the first adjusting rack and the second adjusting rack; 3. By the rotatably arranged clamping block, when the rolling wear detection and sliding wear detection are carried out on the same surface of the plating part, when the sliding detection roller rises and falls, the clamping block rotates, so that the surface of the sliding detection roller in contact with the plating part is always the same as the surface of the rolling detection roller in contact with the plating part, thereby improving the accuracy of the wear resistance detection.

Detailed implementation manners

[0035] The following Figures 1-5 further elaborates on this application in conjunction with the attached

[0036] An embodiment of this application discloses a detection device for the wear resistance of a metal plating layer. Referring to Figure 1 , a detection device for the wear resistance of a metal plating layer includes a vertically arranged frame 1, a sliding wear detection assembly 2 and a rolling wear detection assembly 3 which are arranged on the frame 1 and are arranged in a lifting manner on the frame 1. There are also two groups of oppositely arranged clamping blocks 11 on the frame 1. The two groups of clamping blocks 11 are arranged oppositely in the horizontal direction, and the two groups of clamping blocks 11 enclose a "U" shape. A clamping groove 12 is opened on the clamping block 11. The plated part is movably clamped in the clamping groove 12. The two groups of clamping blocks 11 movably clamp the plated part, and the clamping blocks 11 remain horizontal under normal conditions.

[0037] The sliding wear detection assembly 2 includes a first mounting rod 21 that is vertically lifted and rotatably arranged on the frame 1 and a sliding detection roller 22 that is rotatably arranged on the mounting rod. The sliding direction of the first mounting rod 21 is consistent with the height direction of the frame 1. The end side of the sliding detection roller 22 is in contact with the surface of the plated part. The rotation axis of the sliding detection roller 22 is consistent with the height direction of the frame 1. A torque sensor 23 is provided on the sliding detection roller 22, and a first rotation motor 24 for driving the first mounting rod 21 to rotate is provided on the frame 1.

[0038] The rolling wear detection assembly 3 includes a second mounting rod 31 that is vertically lifted and rotatably arranged on the frame 1 and a rolling detection roller 32 that is rotatably arranged on the second mounting rod 31. A first bevel gear 33 is coaxially provided on the second mounting rod 31, and a second bevel gear 34 is coaxially provided on the rolling detection roller 32. The first bevel gear 33 meshes with the second bevel gear 34. The circumferential surface of the rolling detection roller 32 is in movable contact with the surface of the plated part. The rotation axis of the rolling detection roller 32 is perpendicular to the height direction of the frame 1. A torque sensor 23 is also provided on the rolling detection roller 32, and a second rotation motor 35 for driving the second mounting rod 31 to rotate is provided on the frame 1.

[0039] The first mounting rod 21 and the second mounting rod 31 are arranged opposite to each other, and the sliding detection roller 22 is located directly above the rolling detection roller 32. A switching member 4 for lifting and adjusting the first mounting rod 21 and the second mounting rod 31 according to the detection requirements of the plated part is further provided on the frame 1.

[0040] Since conventional metal plated parts are used as instrument shells or connecting components, when used as instrument shells, they are often subject to more rolling wear; when used as connecting components, they are subject to more sliding wear; and at the connecting parts of some precision instruments, cooling oil or lubricating oil is often required for cooling or lubrication, and the presence of cooling oil and lubricating oil will cause both rolling wear and sliding wear to occur simultaneously at the connecting parts. Therefore, for different usage conditions and usage scenarios, it is necessary to detect sliding wear and rolling wear.

[0041] First, standard parts (two types with and without plating) need to be placed in the clamping groove 12 of the clamping block 11. The standard readings are obtained by judging the readings of the torque sensors 23 on the sliding detection roller 22 and the rolling detection roller 32, and the readings of the plated and non-plated parts in the standard state are obtained. Thus, during the test, the wear resistance of the plated part is judged according to the readings of the torque sensor 23 and the number of rotations of the sliding detection roller 22 / rolling detection roller 32.

[0042] When performing rolling wear detection on one side of the plated part and sliding wear detection on the other side of the plated part, at this time, the first mounting rod 21 and the second mounting rod 31 are brought closer by the switching member 4, so that the sliding detection roller 22 is in contact with the surface of the plated part, and the rolling detection roller 32 is in contact with the other surface of the plated part. The sliding detection roller 22 and the rolling detection roller 32 rotate simultaneously. By reading the readings of the torque sensors 23 on the sliding detection roller 22 and the rolling detection roller 32, and corresponding the number of rotations of the sliding detection roller 22 and the rolling detection roller 32, the wear resistance of the plated part is obtained.

[0043] Referring to Figure 1 and Figure 2 When performing sliding wear detection on one side of the plated part and rolling wear detection on the other side, the switching member 4 includes a first sliding rack 41 fixedly connected to the first mounting rod 21, a second sliding rack 42 connected to the second mounting rod 31, and a sliding gear 43 that meshes with the first sliding rack 41 and the second sliding rack 42. The sliding directions of the first sliding rack 41 and the second sliding rack 42 are both consistent with the height direction of the frame 1. The first sliding rack 41 and the second sliding rack 42 are respectively located on opposite sides of the sliding gear 43, and the rotation axis of the sliding gear 43 is horizontal.

[0044] When it is necessary to perform sliding wear detection on one side of the plated part and rolling wear detection on the other side, the sliding gear 43 meshes with both the first sliding rack 41 and the second sliding rack 42. At this time, when the rolling friction roller descends, it drives the first sliding rack 41 to descend. At this time, the first sliding rack 41 drives the meshing sliding gear 43 to rotate, thereby driving the second sliding rack 42 to rise, so as to drive the sliding friction roller to be in contact with the bottom side of the plated part, so as to perform wear resistance detection on both sides of the plated part at the same time, and improve the wear resistance detection efficiency of the plated part.

[0045] A controller 13 is also provided on the frame 1. The controller 13 is electrically connected to the first rotation motor 24 and the second rotation motor 35. The controller 13 controls the rotation periods of the first rotation motor 24 and the second rotation motor 35. After judging the theoretical values of the rolling wear and sliding wear ratios of the plated part under the working conditions according to the actual situation, the controller 13 controls the rotation periods of the first rotation motor 24 and the second rotation motor 35, so as to adjust different sliding wear detection and rolling wear detection periods according to the actual situation.

[0046] In some actual application scenarios, the plated part will have both sliding wear and rolling wear at the same time. Therefore, it is necessary to judge the wear resistance of the plated part in such application scenarios. Therefore, referring to Figure 2, the switching member 4 includes a first adjusting rack 44 connected to the first mounting rod 21 and a second adjusting rack 45 connected to the second mounting rod 31. The clamping block 11 is rotatably arranged on the frame 1. An adjusting gear 46 is provided at the rotating shaft of the clamping block 11. The adjusting gear 46 is movably engaged with the first adjusting rack 44 and the second adjusting rack 45. The first adjusting rack 44 and the second adjusting rack 45 move up and down synchronously.

[0047] Thus, when performing rolling wear detection and sliding wear detection on the same surface of the plated part, at this time, the adjusting gear 46 is engaged with the first adjusting rack 44 and the second adjusting rack 45. Thus, when the sliding detection roller 22 descends, it drives the rolling detection roller 32 to descend, and when the sliding detection roller 22 ascends, it drives the rolling detection roller 32 to ascend. During the ascending and descending processes, the clamping block 11 rotates synchronously, so as to realize the wear resistance detection of the same surface of the plated part.

[0048] In order to realize the switching between the two detection states, an adjusting member 47 is further provided on the frame 1. Refer to Figure 2 , the adjusting member 47 includes a connecting shaft 471 slidably arranged on the frame 1. A connecting gear 474 is provided on the connecting shaft 471. The sliding gears 43 are all arranged on the connecting shaft 471. The connecting gear 474 is movably engaged with the first adjusting rack 44, the second adjusting rack 45 and the adjusting gear 46. A connecting block 472 is further slidably arranged on the connecting shaft 471. A clamping groove 473 is formed on the connecting block 472. One ends of the first adjusting rack 44 and the second adjusting rack 45 close to each other are movably clamped with the corresponding clamping grooves 473. The adjusting gear 46 is movably engaged with the connecting gear 474, and the connecting gear 474 and the connecting block 472 are always engaged.

[0049] When it is necessary to adjust to perform rolling wear and sliding wear detection on the same surface of the plated part, at this time, the technician pulls the connecting shaft 471 to drive the adjusting gear 46 and the sliding gear 43 to slide, so that the sliding gear 43 is separated from the first sliding rack 41 and the second sliding rack 42. At this time, the connecting block 472 arranged on the connecting shaft 471 is clamped with the first adjusting rack 44 and the second adjusting rack 45, so as to realize the connection of the first adjusting rack 44 and the second adjusting rack 45, and at the same time realize the engagement of the adjusting gear 46 with the first adjusting rack 44 and the second adjusting rack 45, and further realize the synchronous lifting of the sliding detection roller 22 and the rolling detection roller 32, and further realize the wear resistance detection of the same surface of the plated part.

[0050] At the same time, since when the plated part is used as a connecting component, the problems of rolling wear and sliding wear often occur simultaneously under the action of lubricating oil or cooling oil. Therefore, when performing rolling wear and sliding wear detection on the same surface, in order to more accurately obtain the wear resistance of the plated part, it is often necessary to simulate the actual use conditions of the plated part. Therefore, refer to Figure 3 andFigure 4 The clamping block 11 is hollowly arranged, and the cavity inside the clamping block 11 is communicated with the liquid storage tank 5. Coating holes 51 are formed on the inner side walls of the clamping block 11 in the clamping grooves 12. A plurality of coating holes 51 are formed, and the plurality of coating holes 51 are all arranged towards the center of the surface of the workpiece to be plated. A liquid storage tank 5 communicated with the coating holes 51 is arranged on the machine frame 1. An environmental liquid simulating the working conditions of the workpiece to be plated is stored in the liquid storage tank 5. The environmental liquid can be any one of water, coolant, lubricating oil, and lithium grease, and is selected according to the requirements of the reagent workpiece to be plated.

[0051] Referring to Figure 4 and Figure 5 , when the environmental liquid needs to be extruded, it is when the clamping block 11 is turned over. Therefore, an extrusion member 52 is also arranged on the machine frame 1. The extrusion member 52 includes a sliding plate 522 slidably arranged in the clamping block 11. An adjusting screw rod 521 is arranged on the machine frame 1. The adjusting screw rod 521 is threadedly adapted to the sliding plate 522. A circulation hole is formed on the sliding plate 522. A first blocking plate 523 is rotatably arranged at the coating hole 51. A second blocking plate 524 is arranged at the circulation hole. The rotation directions of the first blocking plate 523 and the second blocking plate 524 are the same. When the sliding detection roller 22 rises, the sliding plate 522 slides towards the coating hole 51, and the first blocking plate 523 opens the coating hole 51, and the second blocking plate 524 closes the circulation hole; when the sliding detection roller 22 descends, the sliding plate 522 slides away from the coating hole 51, the second blocking plate 524 opens the circulation hole, and the first blocking plate 523 closes the coating hole 51.

[0052] Since during a single test, that is, when the sliding wear and rolling wear tests are not carried out simultaneously, if the lubrication of the environmental liquid is added, it will instead affect the accuracy of the test results. Therefore, for the accuracy of the test results and to reduce the waste of the environmental liquid, a connecting block 532 is arranged on the machine frame 1. The connecting block 532 is hollowly arranged. The connecting block 532 is movably communicated with the liquid storage tank 5 and the clamping block 11. To reduce the waste of the environmental liquid, an opening and closing member 53 is arranged on the connecting block 532. The opening and closing member 53 includes a sliding block 531 slidably arranged on the machine frame 1. The sliding block 531 is connected to the connecting shaft 471. An opening and closing block 533 is slidably arranged on the connecting block 532. The opening and closing block 533 is elastically arranged on the connecting block 532. One end side of the opening and closing block 533 is movably attached and abutted against the sliding block 531. The other end side of the opening and closing block 533 is inserted into the connecting block 532 to movably block the connecting block 532.

[0053] The implementation principle of the coating wear resistance detection equipment for metal plated parts in the embodiments of this application is as follows: Before detecting the wear resistance of metal plated parts, first, relevant technicians place standard parts (two types with and without coatings) in the clamping grooves 12 of the clamping blocks 11, and judge the standard readings by the readings of the torque sensors 23 on the sliding detection rollers 22 and the rolling detection rollers 32, so as to obtain the readings of the parts with and without coatings under the standard state.

[0054] Immediately afterwards, relevant technicians determine whether the plated parts need to be detected on one side or both sides during the wear resistance detection according to the usage conditions of the plated parts, whether it is necessary to conduct sliding wear and rolling wear detection on one side at the same time, or to conduct sliding wear detection or rolling wear detection on both sides separately.

[0055] Then, at this time, relevant technicians place the plated parts to be detected in the clamping grooves 12 of the clamping blocks 11. When it is necessary to conduct rolling wear detection on one side of the plated parts and sliding wear detection on the other side, at this time, the technicians adjust the position of the connecting shaft 471 so that the sliding gear 43 meshes with both the first sliding rack 41 and the second sliding rack 42. At this time, when the rolling friction roller descends, it drives the first sliding rack 41 to descend. At this time, the first sliding rack 41 drives the meshing sliding gear 43 to rotate, thereby driving the second sliding rack 42 to rise, so as to drive the sliding friction roller to fit with the bottom side of the plated parts. The wear resistance of the plated parts is judged according to the change of the readings of the torque sensor 23 and the number of turns of the sliding detection roller 22 / rolling detection roller 32.

[0056] When conducting sliding wear detection and rolling wear detection on the same side of the plated parts, the technicians adjust the position of the connecting shaft 471 so that the connecting gear 474 slides to the position meshing with the adjusting gear 46. When the first mounting rod 21 descends, at this time, the first adjusting rack 44 descends under the drive of the first mounting rod 21, and the first adjusting rack 44 and the second adjusting rack 45 descend synchronously, so that when the sliding detection roller 22 fits with the surface of the plated parts, the rolling detection roller 32 separates from the surface of the plated parts.

[0057] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
