Description

Technical Field

[0001] This utility model relates to the technical field of spring hardness testing equipment, specifically a testing platform for hot-rolled heavy-duty suspension springs. Background Technology

[0002] Hot-rolled heavy-duty suspension springs are important components used to support and cushion heavy vehicles or machinery. They are usually made of high-strength steel through a hot-rolling process. During the production process, in order to ensure that the quality and performance of the springs meet the design requirements, especially to maintain stability and reliability under heavy loads and complex working conditions, it is crucial to perform hardness testing.

[0003] Publication No. CN217006804U discloses a hardness testing device for suspension spring production. This device involves an operator loosening a second set screw, placing the lower part of the Leeb hardness tester's probe inside a cylinder, and then tightening the second set screw to secure the probe and prevent it from slipping during testing. The operator then loosens a first set screw, opens the Leeb hardness tester, and holds a square guide rod, moving it until the lower end of the probe contacts the outermost edge of the spring, allowing the tester to measure the spring's hardness. However, this patent has the following problems in practical use:

[0004] The device works by having the operator hold and move a square guide rod until the lower end of the Leeb hardness tester's testing rod contacts the outermost part of the spring, allowing the Leeb hardness tester to measure the spring's hardness. However, this device can only test the top of the spring, and the spring's hardness characteristics may vary at different locations. In particular, if there is inhomogeneity in the material or process during the spring's manufacturing process, testing only the top may not accurately reflect the overall hardness of the spring, thus reducing the accuracy and reliability of the test and causing inconvenience to the operator.

[0005] A testing platform for hot-rolled heavy-duty suspension springs is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a testing platform for hot-rolled heavy-duty suspension springs, which solves the problem mentioned in the background art. Currently, the method involves an operator holding a square guide rod and moving it so that the lower end of the Leeb hardness tester's testing rod contacts the outermost part of the spring, allowing the Leeb hardness tester to test the spring's hardness. However, this device can only test the top of the spring, and the hardness characteristics of the spring may vary at different locations. In particular, if there is inhomogeneity in the material or process during the manufacturing process of the spring, testing only the top may not accurately reflect the overall hardness of the spring, thus reducing the accuracy and reliability of the test.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a testing platform for hot-rolled heavy-duty suspension springs, comprising a base, wherein a fixing plate is detachably connected to one side of the top of the base; an adjustment mechanism is provided on the top of the base, and a fixing component is provided on one side of the fixing plate;

[0008] The adjustment mechanism includes symmetrically arranged grooves on the top of the base, with a screw rotatably connected between the grooves and the base. A threaded block is threaded onto the outside of the screw, and a support plate is fixedly mounted on the top of the threaded block. A sprocket is fixedly connected to one end of the screw, and a chain is meshed between the sprockets. An annular plate is fixedly mounted on the top of the support plate, with insertion holes on its outer surface. A slide block is slidably connected to the outer surface of the annular plate, with a hole block fixedly connected to one end of the slide block. A fixing knob is threaded onto one side of the hole block. A limit box is fixedly mounted on the top of the slide block, and a slide rod is slidably connected inside the limit box. A sliding plate is fixedly connected to the bottom of the slide rod, and an insertion rod is fixedly connected to the bottom of the sliding plate. The bottom of the insertion rod is inserted into the insertion hole, and a telescopic spring is sleeved on the outside of the slide rod.

[0009] Preferably, the fixing assembly includes a support column fixedly installed on one side of the fixing plate, and a fixing box is symmetrically fixedly connected to the upper interior of the fixing plate. Sliding grooves are symmetrically opened on both sides of the support column. A rotating rod is rotatably connected between the sliding grooves, the support column, the fixing plate, and the fixing box. Bidirectional helical teeth are symmetrically welded to the outer ends of the rotating rod. A moving block is symmetrically threaded onto the outer side of the bidirectional helical teeth. A connecting rod is rotatably connected to one side of the moving block. A pressing plate is rotatably connected to the end of the connecting rod away from the support column. An arc-shaped plate is fixedly installed on the side of the pressing plate away from the support column. An arc-shaped rubber pad is fixedly installed on the outer side of the arc-shaped plate. A driving rod is rotatably connected between the fixing plate and the fixing box. A forward and reverse motor is fixedly connected to the top of the driving rod. A first conical tooth is symmetrically fixedly installed on the outer side of the driving rod, and a second conical tooth is fixedly installed on the end of the rotating rod near the fixing box.

[0010] Preferably, a rotating seat is symmetrically fixedly installed on one side of the top of the base, and a rotating plate is rotatably connected between the rotating seats. A card seat is fixedly installed at one end of the support column, and a protrusion is fixedly connected to the top of the rotating plate. A groove is provided on one side of the card seat, and the protrusion and the groove are engaged.

[0011] Preferably, a knob rod is threadedly connected between the rotating seat and the rotating plate.

[0012] Preferably, a handle is fixedly installed at one end of the screw.

[0013] Preferably, the bottom of the forward and reverse motor is fixedly connected to the fixing plate.

[0014] Preferably, the first conical tooth and the second conical tooth are engaged in a meshing connection.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This testing platform for hot-rolled heavy-duty suspension springs is described in detail below: Through the cooperation between the sprocket and the chain, two sets of screws rotate synchronously and in the same direction. The rotation of the screws drives the movement of the threaded block, and the movement of the support plate drives the movement of the annular plate, achieving the effect of lateral adjustment. At this time, the operator places the LB model Leeb hardness tester into the internal slot of the hole block, and then tightens the fixing knob to press and fix the Leeb hardness tester. At this time, the operator slides the slide block outside the annular plate to achieve the effect of longitudinal adjustment. Then, the operator presses the button on the top of the Leeb hardness tester to achieve the effect of spring hardness testing, thereby achieving the effect of rapid adjustment and testing of springs. The rapid longitudinal and lateral adjustment method can greatly improve the flexibility of spring testing, meet the effect of multi-point spring testing, and greatly improve the accuracy of spring testing. The return of the telescopic spring is achieved through... This design allows for the insertion of the insertion rod into the insertion hole, enabling rapid adjustment and fixing of the slide block. This effectively prevents the Leeb hardness tester from deviating during spring testing, significantly improving the stability of the device. A forward and reverse motor drives the rotation of the drive rod. The rotation of the first conical tooth drives the rotation of the second conical tooth, which in turn drives the rotation of two sets of rotating rods. The rotation of the rotating rods drives the rotation of two sets of bidirectional helical teeth, which in turn moves two sets of moving blocks. The movement of the moving blocks moves the connecting rod, which in turn moves the extrusion plate. The movement of the arc-shaped plate moves the arc-shaped rubber pad, which in turn moves the two sets of arc-shaped rubber pads outward to compress and fix the inner side of the spring. The arc-shaped rubber pads deform under this compression, enabling rapid adjustment and fixing of the spring. This design can meet the testing requirements of various spring specifications, greatly improving the flexibility of the device.

[0016] 1. By rotating the screw, the operator drives the sprocket to rotate. Through the cooperation between the sprocket and the chain, two sets of screws rotate synchronously and in the same direction. The rotation of the screws causes the threaded block to move, which in turn moves the support plate. The movement of the support plate then moves the annular plate, achieving lateral adjustment. The operator then places the LB model Leeb hardness tester into the slot inside the hole block and tightens the fixing knob to compress and fix the Leeb hardness tester. The operator then slides the slide block outside the annular plate to achieve longitudinal adjustment. Finally, pressing the button on the top of the Leeb hardness tester allows for spring hardness testing. This enables rapid adjustment and testing of the spring. The rapid longitudinal and lateral adjustment greatly improves the flexibility of spring testing, allowing for multi-point spring testing and significantly enhancing the performance of the spring. The high accuracy during testing provides convenience for operators. By pulling the sliding rod inside the limit box, the rod moves the sliding plate, causing the telescopic spring to contract under the pressure of the sliding plate. Through the spring's restoring property, the insertion rod can be inserted into the insertion hole, enabling quick adjustment and fixing of the sliding block. This effectively prevents the Leeb hardness tester from deviating during spring testing, greatly improving the stability of the device. The rotating plate, moved between the two sets of rotating seats, causes the protrusion to rotate, engaging with the inner groove of the card seat. This quickly supports the support column, reducing the risk of tilting due to excessive spring weight and improving the stability of the device.

[0017] 2. The worker places the spring onto the outside of the two sets of arc-shaped rubber pads. The worker then starts the forward and reverse motors, which rotate the drive rod. The rotation of the drive rod rotates the two sets of first conical teeth, which in turn rotate the second conical teeth. The second conical teeth rotate the two sets of rotating rods, which in turn rotate the two sets of bidirectional helical teeth. The bidirectional helical teeth then move the two sets of moving blocks. These moving blocks move in a convergent-spreading trajectory, which in turn moves the connecting rod. The rotation of the connecting rod pushes the extrusion plate, which in turn moves the arc-shaped plate. The arc-shaped plate then moves the arc-shaped rubber pads, causing them to move outwards. This outward movement of the arc-shaped rubber pads then compresses and fixes the inner side of the spring. The compressed and deformed arc-shaped rubber pads achieve rapid adjustment and fixation of the spring, and can meet the testing requirements of various spring specifications, greatly improving the flexibility of the device.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides a technical solution: a testing platform for hot-rolled heavy-duty suspension springs, including a base 1, a fixing plate 101 detachably connected to one side of the top of the base 1; an adjustment mechanism 2 is provided on the top of the base 1, and a fixing component 3 is provided on one side of the fixing plate 101.

[0026] The adjusting mechanism 2 includes symmetrically arranged grooves 201 on the top of the base 1, and a screw 202 is rotatably connected between the grooves 201 and the base 1. A threaded block 203 is threadedly connected to the outside of the screw 202, and a support plate 204 is fixedly installed on the top of the threaded block 203. A sprocket 205 is fixedly connected to the outside of one end of the screw 202, and a chain 206 is meshed between the sprockets 205. An annular plate 207 is fixedly installed on the top of the support plate 204. Furthermore, the annular plate 207 has insertion holes 208 on its exterior, and a slide block 209 is slidably connected to the exterior of the annular plate 207.

A slide plate 214 is fixedly connected to the bottom of the slide rod 213, and the bottom of the slide plate 214 is fixedly connected to... The device includes a rod 215, the bottom of which is inserted into the insertion hole 208. A telescopic spring 216 is sleeved on the outside of the slide rod 213, enabling rapid adjustment of the spring. This rapid longitudinal and transverse adjustment greatly improves the flexibility of spring testing, allowing for multi-point spring testing and significantly enhancing accuracy. It also provides convenience for operators. When the operator pulls the slide rod 213, it slides within the limit box 212. This causes the slide rod 213 to move the sliding plate 214, compressing the telescopic spring 216. Releasing the slide rod 213 allows the telescopic spring 216 to return to its original position, allowing the rod 215 to be inserted into the insertion hole 208. This enables rapid adjustment of the fixed slide 209, effectively preventing the Leeb hardness tester from shifting during spring testing. This significantly improves the stability of the device and provides convenience for operators.

A groove 221 is provided on one side of the retaining seat 219, and the protrusion 220 is engaged with the groove 221. When the operator rotates the rotating plate 218 between the two sets of rotating seats 217, the rotation of the rotating plate 218 drives the rotation of the protrusion 220. At this time, the protrusion 220 and the groove 221 are engaged. The inner grooves 221 of the card holder 219 engage to quickly support the support column 301, thereby reducing the tilting of the support column 301 caused by excessive spring weight and improving the stability of the device during use. A knob rod 222 is threadedly connected between the rotating seat 217 and the rotating plate 218. By tightening the knob rod 222, the rotating plate 218 can be threaded and fixed. A handle 223 is fixedly installed at one end of the screw 202, which facilitates the operation of the screw 202 by the operator.

[0028] The fixing component 3 includes a support column 301 fixedly installed on one side of the fixing plate 101, and a fixing box 302 symmetrically fixedly connected to the upper interior of the fixing plate 101.

A rotating rod 304 is rotatably connected between the sliding grooves 303, the support column 301, the fixing plate 101, and the fixing box 302. Bidirectional helical teeth 305 are symmetrically welded to the outer ends of the rotating rod 304, and a moving block 306 is symmetrically threaded onto the outer side of the bidirectional helical teeth 305. A connecting rod 307 is rotatably connected to one side of the moving block 306, and a pressing plate 308 is rotatably connected to the end of the connecting rod 307 away from the support column 301. An arc-shaped plate is fixedly installed on the side of the pressing plate 308 away from the support column 301. 309, and an arc-shaped rubber pad 310 is fixedly installed on the outside of the arc plate 309, and a drive rod 311 is rotatably connected between the fixed plate 101 and the fixed box 302, and a forward and reverse motor 312 is fixedly connected to the top of the drive rod 311, and the bottom of the forward and reverse motor 312 is fixedly connected to the fixed plate 101. A first conical tooth 313 is symmetrically fixedly installed on the outside of the drive rod 311, and a second conical tooth 314 is fixedly installed on the end of the rotating rod 304 near the fixed box 302. The first conical tooth 313 and the second conical tooth 314 are meshed and connected, thereby achieving the effect of quickly adjusting and fixing the spring, and meeting the detection effect of springs of various specifications, greatly improving the flexibility of the device and bringing convenience to the staff when using it.

[0029] Working principle: Before using this testing platform for hot-rolled heavy-duty suspension springs, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5As shown, the operator rotates screw 202, which drives sprocket 205 to rotate. Through the cooperation between sprocket 205 and chain 206, the two sets of screws 202 rotate synchronously and in the same direction. The rotation of screw 202 drives the movement of threaded block 203, which in turn drives the movement of support plate 204. The movement of support plate 204 then drives the movement of annular plate 207, achieving the effect of lateral adjustment. At this time, the operator places the LB210 Leeb hardness tester in the internal groove of hole block 210 and then tightens the fixing knob 211. The Leeb hardness tester is pressed and fixed. The operator slides the slide block 209 outside the annular plate 207 to achieve longitudinal adjustment. Then, the operator presses the button on the top of the Leeb hardness tester to test the spring hardness, enabling rapid adjustment of the spring. This rapid longitudinal and transverse adjustment greatly improves the flexibility of spring testing, allowing for multi-point spring testing and significantly improving accuracy. It also provides convenience for the operator. The operator pulls the slide rod 213, which slides inside the limit box 212. This causes the slide plate 214 to move, compressing the telescopic spring 216. Releasing the slide rod 213 allows the telescopic spring 216 to return to its original position, enabling the insertion rod 215 to engage with the insertion hole 208. This allows for rapid adjustment and fixing of the slide block 209, effectively preventing the Leeb hardness tester from shifting during spring testing and greatly improving the stability of the device. It also provides convenience for the operator. The operator then rotates the plate 2... 18 rotates between two sets of rotating seats 217. At this time, the rotation of the rotating plate 218 drives the rotation of the protrusion 220. The protrusion 220 is engaged with the inner groove 221 of the card seat 219, thereby achieving the effect of quickly supporting the support column 301. This reduces the phenomenon of the support column 301 tilting due to excessive spring weight, and improves the stability of the device during use. The rotating plate 218 can be fixed by threading by the operator tightening the knob rod 222. The design of the handle 223 makes it easy for the operator to operate the screw 202.

[0030] The worker places the springs around the two sets of arc-shaped rubber pads 310. Then, the worker starts the forward and reverse motor 312, which drives the drive rod 311 to rotate. The rotation of the drive rod 311 drives the rotation of the two sets of first conical teeth 313, which in turn drives the rotation of the second conical teeth 314. The rotation of the second conical teeth 314 drives the rotation of the two sets of rotating rods 304, which in turn drives the rotation of the two sets of bidirectional helical teeth 305. The rotation of the bidirectional helical teeth 305 drives the movement of the two sets of moving blocks 306. At this time, the two sets of moving blocks 306 move along a convergence and unfolding trajectory. The movement of the moving blocks 306... The movement of the connecting rod 307 drives the movement of the connecting rod 307, which in turn drives the movement of the extrusion plate 308. The movement of the extrusion plate 308 drives the movement of the arc plate 309, which in turn drives the movement of the arc rubber pad 310. At this time, the two sets of arc rubber pads 310 move outward, thereby using the outward movement of the two sets of arc rubber pads 310 to compress and fix the inner side of the spring. At this time, the arc rubber pad 310 is deformed by compression, thereby achieving the effect of quickly adjusting and fixing the spring, and meeting the testing effect of springs of various specifications. This greatly improves the flexibility of the device and brings convenience to the staff during use.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
