Description

Technical Field

[0001] This utility model belongs to the field of testing equipment technology, and in particular relates to a device for testing the corrosion resistance of metal products. Background Technology

[0002] Metal products are widely used and loved for their unique advantages in daily life and work, such as metal knives and metal trays. However, due to the variable and humid nature of the environment, metal products are prone to rusting or corrosion, affecting their usability. Therefore, corrosion resistance testing is necessary during the production of metal products to assess their corrosion resistance and facilitate improvements. However, this corrosion resistance testing is mostly done manually, which is inefficient and cannot adequately meet the production needs of enterprises.

[0003] To address this, Chinese Patent CN206431027U discloses a metal product corrosion resistance testing device, comprising a workbench, a housing, a support plate, a motor, a first rotating rod, a first sector gear, a bracket, a first slide rail, a first slider, a first rack, and a moving plate. The housing is placed at the top center of the workbench, and a support plate is welded to the left side of the top of the workbench. A support plate is welded to the lower left side of the support plate, and a motor is connected to the upper part of the support plate via bolts. In use, the operator removes the fixing piece from the pin, then removes the pin from the small hole, places the metal product body between the left and right clamping plates, and then moves the clamping plates to clamp the metal product body. After clamping, the operator inserts the pin into the small hole and then inserts the fixing piece into the left side of the pin, thereby fixing the metal product body. The motor rotates, causing the metal product body to move up and down continuously, allowing it to continuously contact the acid or alkali solution, thus achieving the purpose of testing the acidity or alkalinity of the metal product body.

[0004] However, the above-mentioned device requires the pins and clamps to be fixed and operated repeatedly in sequence to inspect multiple workpieces one by one. The unloading operation after inspection is also carried out in the same way, which is time-consuming and labor-intensive, affecting the continuity of inspection work and thus affecting the efficiency of inspection work. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a metal product corrosion resistance testing device. It features automated lifting and lowering of the positioning frame, replacing manual adjustment; batch clamping of workpieces without individual fixing; and automatic release of the adjusting clamps during unloading. This avoids the tedious repetitive manual operations of traditional methods, saving time and effort, ensuring continuous testing, and effectively improving work efficiency. It solves the problems of existing technologies that require sequential fixing and repeated operation of pins and clamps to test multiple workpieces individually, followed by the same unloading operation after testing, which is time-consuming, labor-intensive, and affects the continuity of testing work, thus impacting efficiency.

[0006] This utility model is implemented as follows: a metal product corrosion resistance testing device includes a support base, a test liquid storage tank installed at the bottom inner side of the support base, a positioning frame located directly above the test liquid storage tank, a lead screw rotatably mounted on the inner side wall of the support base, a lifting plate threaded onto the lead screw, the end of the lifting plate being fixedly connected to the outer wall of the positioning frame, a threaded rod connected to the positioning frame via a bearing, an adjusting clamp threaded onto the threaded rod, the adjusting clamp sliding along the inside of the positioning frame, the adjusting clamp being used to clamp and fix several workpieces within the positioning frame, a bottom support plate located below the positioning frame, the left side of the bottom support plate sliding back and forth along the inner side of the support base.

[0007] In a preferred embodiment of this utility model, the inner sidewall of the support base is provided with a guide groove, the upper and lower ends of the lead screw are connected to the guide groove through bearings, the lifting plate slides up and down along the guide groove, a motor is fixedly installed inside the support base, the output end of the motor is fixedly connected to the lower end of the lead screw, and a drive wheel is sleeved and fixedly attached to the upper end of the lead screw.

[0008] This design facilitates the rotation of the lead screw, and the guide groove guides the movement of the lifting plate. This, in turn, allows the lifting plate to move the positioning frame up and down, making it easier to move the workpiece in the positioning frame into the testing liquid storage tank for testing.

[0009] In a preferred embodiment of this invention, a vertical rotating rod is connected to the inner top of the support base via a bearing. A first bevel gear and a driven wheel are fixedly sleeved on the vertical rotating rod. The driven wheel and the driving wheel are connected by a transmission belt. A support plate is fixedly connected to the right end of the inner top of the support base. A horizontal rotating rod is connected to the support plate via a bearing. A second bevel gear and a gear post are fixedly sleeved on the horizontal rotating rod. The second bevel gear and the first bevel gear are meshed together.

[0010] With this configuration, the driven wheel and the vertical rotating rod can be easily rotated by the driving wheel and the transmission belt, which in turn causes the first bevel gear to rotate. The first bevel gear drives the horizontal rotating rod to rotate through the second bevel gear, which in turn causes the gear column to rotate.

[0011] As a preferred embodiment of this utility model, a gear ring is sleeved and fixed at the outer end of the threaded rod, and the gear ring and the gear column are meshed together when the material is unloaded.

[0012] With this setup, after inspection, when unloading, the lifting plate moves the positioning frame, adjusting clamp, threaded rod, and gear ring upwards until the gear ring reaches the meshing connection with the gear column. The gear column drives the gear ring to rotate, causing the threaded rod to rotate, which in turn moves the adjusting clamp along the threaded rod and releases the workpiece. Multiple workpieces are released simultaneously. The receiving box can then be used to catch the released workpieces. At this point, the lifting plate disengages from the threaded section of the screw and stops moving. This device eliminates the need for workers to individually release each workpiece, thus completing the batch workpiece release operation. This significantly shortens the unloading time, avoids the tediousness and time-consuming nature of manual operation, effectively ensures the continuity of inspection work, and further improves inspection efficiency.

[0013] In a preferred embodiment of this invention, clamping blocks are fixedly connected to the opposite surfaces of the adjusting clamping plate and the positioning frame, and sponge pads are fixedly connected to the end faces of the clamping blocks, so that the workpiece is clamped and fixed between the corresponding clamping blocks.

[0014] This setting facilitates the clamping and fixing of multiple workpieces, making it convenient to use.

[0015] As a preferred embodiment of this utility model, the inner sidewall of the support base is fixedly connected to two corresponding slide rails, the guide groove is located between the slide rails, the bottom support plate slides along the inside of the slide rails, the bottom of the bottom support plate is fixedly connected to a limiting slider, the bottom of the slide rails is provided with a limiting slide path, and the limiting slider slides along the limiting slide path.

[0016] With this setup, the slide rail provides a stable front and rear sliding track for the base plate. When loading, it facilitates stable support for the bottom of the workpiece. When unloading, it facilitates sliding away from the bottom of the positioning frame, allowing the workpiece to move up and down for inspection.

[0017] In a preferred embodiment of this invention, a baffle is fixedly connected to the guide groove, the lead screw passes through the baffle, and the lifting plate and the baffle are fixedly connected by a spring, the spring being sleeved on the lead screw.

[0018] This feature allows for the flexible extension and retraction of the lifting platform, improving the stability of the lifting operation.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: it realizes the automatic lifting and lowering of the positioning frame, replacing manual adjustment. With the threaded rod and adjusting clamp on the positioning frame, workpieces can be clamped in batches without the need for individual fixing, greatly reducing manual operation. Moreover, when unloading, the adjusting clamp can automatically release the workpieces in batches, avoiding the tediousness of traditional manual repeated operation, saving time and effort, ensuring the continuity of inspection, and thus effectively improving work efficiency.

[0026] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0027] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] refer to Figures 1 to 5As shown in the figure, an embodiment of the present invention provides a metal product corrosion resistance testing device, including a support base 1, a test liquid storage tank 10 installed at the bottom of the support base 1, a positioning frame 4 provided directly above the test liquid storage tank 10, a lead screw 2 rotatably installed on the inner side wall of the support base 1, a lifting plate 3 threadedly connected to the lead screw 2, the end of the lifting plate 3 being fixedly connected to the outer wall of the positioning frame 4, a threaded rod 5 connected to the positioning frame 4 via a bearing, an adjusting clamp 501 threadedly connected to the threaded rod 5, the adjusting clamp 501 sliding along the inside of the positioning frame 4, the adjusting clamp 501 being used to clamp and fix several workpieces inside the positioning frame 4, a bottom support plate 8 provided below the positioning frame 4, the left side of the bottom support plate 8 sliding back and forth along the inner side of the support base 1.

[0029] Specifically, the inner wall of the support base 1 is provided with a guide groove 101, the upper and lower ends of the lead screw 2 are connected to the guide groove 101 through bearings, the lifting plate 3 slides up and down along the guide groove 101, a motor 201 is fixedly installed inside the support base 1, the output end of the motor 201 is fixedly connected to the lower end of the lead screw 2, and a drive wheel 203 is sleeved and fixed at the upper end of the lead screw 2.

[0030] The above scheme facilitates the rotation of the lead screw 2, and the guide groove 101 guides the movement of the lifting plate 3, which in turn facilitates the lifting plate 3 to drive the positioning frame 4 to move up and down, so as to facilitate the workpiece in the positioning frame 4 to enter the detection liquid storage tank 10 for detection.

[0031] Specifically, a vertical rotating rod 6 is connected to the inner top of the support base 1 via a bearing. A first bevel gear 601 and a driven wheel 602 are sleeved and fixed on the vertical rotating rod 6. The driven wheel 602 and the driving wheel 203 are connected by a transmission belt 204. A support plate 102 is fixedly connected to the right end of the inner top of the support base 1. A horizontal rotating rod 7 is connected to the support plate 102 via a bearing. A second bevel gear 701 and a gear column 702 are sleeved and fixed on the horizontal rotating rod 7. The second bevel gear 701 and the first bevel gear 601 are meshed together.

[0032] Using the above scheme, the driving wheel 203 and the transmission belt 204 can easily drive the driven wheel 602 and the vertical rotating rod 6 to rotate, which in turn causes the first bevel gear 601 to rotate. The first bevel gear 601 drives the horizontal rotating rod 7 to rotate through the second bevel gear 701, which in turn causes the gear column 702 to rotate.

[0033] Specifically, a gear ring 502 is sleeved and fixed at the outer end of the threaded rod 5. When the material is unloaded, the gear ring 502 and the gear column 702 are meshed and connected.

[0034] Using the above scheme, after the inspection is completed, when unloading, the lifting plate 3 drives the positioning frame 4, adjusting clamp 501, threaded rod 5, and gear ring 502 to move upward until the gear ring 502 reaches the meshing connection with the gear column 702. The gear column 702 drives the gear ring 502 to rotate, causing the threaded rod 5 to rotate, which in turn drives the adjusting clamp 501 to move along the threaded rod 5 and release the workpiece. Multiple workpieces are released simultaneously. The hand can hold the receiving box to catch the dropped and released workpieces. At this time, the lifting plate 3 disengages from the threaded section of the screw 2 and stops moving. This device does not require the operator to release the workpieces one by one, which can complete the release operation of batch workpieces, greatly shortening the unloading time, avoiding the tediousness and time-consuming nature of manual operation, effectively ensuring the continuity of the inspection work, and thus further improving the inspection efficiency.

[0035] Specifically, clamping blocks 401 are fixedly connected to the opposite surfaces of the adjusting clamping plate 501 and the positioning frame 4, and sponge pads 402 are fixedly connected to the end faces of the clamping blocks 401. The workpiece is clamped and fixed between the corresponding clamping blocks 401.

[0036] The above solution facilitates the clamping and fixing of multiple workpieces and is easy to use.

[0037] Specifically, the inner wall of the support base 1 is fixedly connected to two corresponding slide rails 9, the guide groove 101 is located between the slide rails 9, the bottom support plate 8 slides along the inside of the slide rail 9, the bottom of the bottom support plate 8 is fixedly connected to a limiting slider 801, the bottom of the slide rail 9 is provided with a limiting slide channel 901, and the limiting slider 801 slides along the limiting slide channel 901.

[0038] Using the above scheme, the slide rail 9 provides a stable front and rear sliding track for the bottom support plate 8. When loading, it is convenient to provide stable support for the bottom of the workpiece. When unloading, it is convenient to slide and pull away from the bottom of the positioning frame 4, so that the workpiece can move up and down for inspection.

[0039] Specifically, a baffle 202 is fixedly connected to the guide groove 101, the lead screw 2 passes through the baffle 202, and the lifting plate 3 and the baffle 202 are fixedly connected by a spring 301, which is sleeved on the lead screw 2.

[0040] The above scheme facilitates the elastic extension and retraction of the lifting plate 3, improving the stability of the lifting operation.

[0041] The working principle of this utility model:

[0042] In use, add an appropriate amount of acid or alkali to the test solution storage tank 10. First, pull the bottom plate 8 forward to move it directly below the positioning frame 4. The bottom plate 8 is positioned between the two sliding rods. Then, insert each workpiece from above the positioning frame 4. The upper part of the workpiece is placed between the clamping blocks 401, the lower part of the workpiece extends out of the positioning frame 4, and the bottom of the workpiece abuts against the bottom plate 8, thus pre-positioning several workpieces. Then, manually rotate the threaded rod 5 to move the adjusting clamp 501 to synchronously clamp and fix the workpieces. Then, start the motor 201 to drive the lead screw 2 to rotate, causing the positioning frame 4 to move up and down, so that the workpieces are continuously immersed in the acid or alkali solution, thus testing the workpieces. Corrosion resistance testing is performed, and the degree of corrosion on the workpiece is observed after a period of time. When unloading, the lifting plate 3 drives the positioning frame 4, threaded rod 5, and gear ring 502 to move upward until the gear ring 502 reaches the meshing connection with the gear column 702, causing the threaded rod 5 to rotate. This then drives the adjusting clamp 501 to move in the opposite direction and release the workpiece. The hand can hold the receiving box to catch the dropped and released workpiece. At this time, the lifting plate 3 disengages from the threaded section of the screw 2 and stops moving. This device greatly shortens the unloading time, avoids the tediousness and time-consuming nature of manual operation, effectively ensures the continuity of the testing work, and thus further improves the testing efficiency.
