Description

Technical Field

[0001] This invention relates to the field of disc spring detection technology, and more specifically, to a disc spring overpressure detection device. Background Technology

[0002] Disc springs are high-strength springs capable of generating enormous elastic force with minimal deformation, and are used in many applications and mechanical equipment. The performance of a disc spring significantly impacts its application effectiveness. Disc springs are primarily conical in shape and can be used individually, in series, or in parallel. They withstand axial static or dynamic loads at their upper inner edge and lower outer edge, deforming upon compression until they are flattened, thus storing energy as a live load.

[0003] Currently, disc springs on the market often have the following technical problems when undergoing overpressure testing:

[0004] Existing disc spring overpressure detection devices often use general-purpose force-applying machinery and related length measuring tools to test disc springs during overpressure testing. This results in the disc spring lacking certain bottom and circumferential positioning and clamping components during the overpressure testing process. Consequently, the disc spring under test will wobble circumferentially due to its own elastic force during the overpressure test, increasing the detection error and reducing the overall data detection effect. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide an overpressure detection device for disc springs that can perform initial clamping and positioning at the bottom and circumferential clamping and positioning, thereby preventing circumferential back-and-forth and left-and-right swaying of the disc springs during subsequent overpressure detection due to their own elasticity. This reduces detection errors during the overpressure detection process and improves the overall data detection effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An overpressure detection device for disc springs includes a detection assembly, a positioning assembly rotatably fitted at the top of the detection assembly, the detection assembly including a detection element and a pressing element fixed on the detection element, and the positioning assembly including a ring element rotatably mounted on the detection element, a positioning element inserted into the top of the ring element, and a sliding element slidably fitted on the detection element.

[0008] The testing component includes a workbench, on the top of which are fixed two symmetrical first arc-shaped plates, and on the top of each of the two first arc-shaped plates are fixed an arc-shaped ring that is rotatably connected to the ring component.

[0009] The pressing component includes a first connecting flange fixed to the detection component, a pressure sensor fixed to the bottom of the first connecting flange, an extension plate fixed to the side of the first connecting flange, an extension rod fixed to the bottom of the extension plate, a sliding ball that slides with the positioning component fixed to the bottom of the extension rod, and a pressing plate fixed to the bottom of the pressure sensor.

[0010] The present invention is further configured such that: the ring component includes two symmetrically arranged semi-circular rings, each of the two semi-circular rings has a semi-circular groove on its inner wall that rotatably engages with the arc-shaped ring, and each of the two semi-circular rings has a connecting lug fixed at its end, and the two connecting lugs are fixedly connected by bolts.

[0011] The present invention is further configured such that: two connecting columns are fixed on the top of the workbench, and threaded columns are fixed on the top of both connecting columns.

[0012] Both of the semicircular rings have a plug rod fixed to their tops.

[0013] The positioning component includes a plug-in ring, and the top of the plug-in ring has two symmetrical plug-in holes, which are respectively plugged into two plug-in rods.

[0014] The invention is further configured such that: a positioning cylinder is fixed to the inner wall of the insertion ring; an annular inclined platform that slides with a sliding ball is fixed to the top of the positioning cylinder; an annular plate is fixed to the inner wall of the positioning cylinder; a plurality of grooves are formed on the inner wall of the annular plate; a plurality of U-shaped plates are fixed to the inner wall of the positioning cylinder above the annular plate; an I-shaped slider is slidably fitted to the inner wall of the U-shaped plate; a lower extension rod is fixed to the bottom of the I-shaped slider; a contact ball is fixed to the bottom of the lower extension rod; the contact ball slides with the grooves and the annular plate in sequence; and an elastic spring is fixed between the I-shaped slider and the U-shaped plate.

[0015] An extension plate is fixed to the side of the I-shaped slider, and a clamping plate is fixed to the side of the extension plate.

[0016] The present invention is further configured such that: two symmetrical arc-shaped springs are fixed on the outer wall of the positioning cylinder, and each of the ends of the two arc-shaped springs is fixed with a sleeve sleeve that fits into the side of the connecting column.

[0017] The top of the positioning cylinder has a downward-extending annular semi-groove.

[0018] The sliding component includes a semi-circular sliding plate that slides inside the annular semi-groove. A semi-circular contact pressure plate that slides with a sliding ball is fixed at the top of the semi-circular sliding plate. The diameter of the sliding ball is smaller than the diameter of the annular semi-groove. The side of the semi-circular contact pressure plate is chamfered. Several return springs are fixed to the bottom of the semi-circular sliding plate and the annular semi-groove.

[0019] The present invention is further configured such that: an inwardly extending groove is provided on the side of the worktable, two symmetrical moving blocks are slidably fitted inside the extension groove, a guide rod is fixed inside the extension groove and slidably fitted through the two moving blocks, a U-shaped clamping plate is fixed at the top of the two moving blocks below the clamping plate, and a first pin is fixed at the bottom of the two moving blocks inside the worktable.

[0020] The inner wall of the workbench is fixed with a U-shaped base plate below the first pin. The U-shaped base plate is slidably fitted with a sliding rail. Two symmetrical second pins are fixed at the top of the sliding rail. A rotating arm is rotatably fitted between the second pins and the first pin.

[0021] The present invention is further configured such that: a threaded rod extending into the interior of a U-shaped base plate is rotatably fitted through an outer side of the worktable; the threaded rod is rotatably connected to a sliding rail; a first limiting ring that fits against the outer side of the worktable is fixed to the periphery of the threaded rod; and a second limiting ring that fits against the inner wall of the U-shaped base plate is fixed to the periphery of the threaded rod.

[0022] The present invention is further configured such that: two symmetrical positioning columns are fixed on the top of the workbench, a top plate is inserted between the two positioning columns, and two symmetrical insertion positioning cylinders are connected to the top of the top plate, and the two insertion positioning cylinders are respectively inserted and fixed to the two positioning columns.

[0023] The top of the top plate has a through hole, and a telescopic cylinder is fixed to the top plate. The telescopic end of the telescopic cylinder is located below the top plate and is fixed to a second connecting flange that is connected and fixed to the first connecting flange.

[0024] The advantages of this invention are: 1. This invention uses the sliding engagement of the sliding ball on the inclined surface of the annular inclined platform to drive the entire positioning assembly to rotate circumferentially inside the detection assembly. This causes several contact balls to slide from the inner wall of the groove to the inner wall of the annular plate, driving several clamping plates to make synchronous radial linear movements inside the annular plate. This allows for the initial clamping and positioning of the bottom disc spring and the overpressure detection of the disc spring after circumferential clamping and positioning. This avoids the disc spring from swaying back and forth and left and right due to its own elasticity during the subsequent overpressure detection, reducing detection errors in the overpressure detection process and improving the data detection effect in the entire detection process.

[0025] 2. This invention rotates the threaded rod, causing the threaded sliding rail connected to it to move away from one side of the worktable inside the U-shaped base plate. This, in turn, causes the rotating arm, which is rotated between the second and first pins, to expand away from each other synchronously. This causes the two moving blocks to move away from each other linearly inside the extension groove. Ultimately, this causes the two U-shaped clamps fixed to the top of the two moving blocks to gradually approach the bottom end of the disc spring to be tested. This provides initial clamping and positioning of the disc spring to be tested, preventing the bottom end of the disc spring to be tested from shaking or shifting during the overpressure test, thereby improving the overpressure test effect of the disc spring to be tested.

[0042] Example 1, please refer to Figure 1-12 The present invention provides the following technical solutions:

[0043] A device for detecting overpressure of a disc spring, specifically comprising a detection assembly 1, a positioning assembly 2 rotatably fitted at the top of the detection assembly 1, the detection assembly 1 including a detection element 3 and a pressing element 4 fixed on the detection element 3, the positioning assembly 2 including a ring element 5 rotatably mounted on the detection element, a positioning element 6 inserted at the top of the ring element 5, and a sliding element 7 slidably fitted on the detection element 3; the detection element 3 including a worktable 301, two symmetrical first arc-shaped plates 302 fixed at the top of the worktable 301, and an arc-shaped ring 303 rotatably mounted on the top of each of the two first arc-shaped plates 302; the pressing element 4 including a first connecting flange 401 fixed on the detection element 3, a pressure sensor 402 fixed at the bottom of the first connecting flange 401, an extension plate 403 fixed on the side of the first connecting flange 401, an extension rod 404 fixed at the bottom of the extension plate 403, a sliding ball 405 slidably fitted with the positioning element 6 fixed at the bottom of the extension rod 404, and a pressing plate 406 fixed at the bottom of the pressure sensor 402;

[0044] Furthermore, the ring component 5 includes two symmetrically arranged semi-circular rings 501. The inner walls of each semi-circular ring 501 are provided with semi-circular grooves 502 that rotatably engage with the arc-shaped ring 303. Connecting ear plates 503 are fixed to the ends of each semi-circular ring 501, and the two connecting ear plates 503 are fixedly connected by bolts. Two connecting pillars 304 are fixed to the top of the worktable 301, and threaded pillars 305 are fixed to the top of each connecting pillar 304. Insertion rods 504 are fixed to the top of each semi-circular ring 501. The positioning component 6 includes an insertion ring 601. Two symmetrical insertion holes 602 are provided through the top of the insertion ring 601, and the two insertion holes 602 respectively engage with the two insertion rods 504. A positioning cylinder 603 is fixed to the inner wall of the insertion ring 601, and an annular inclined platform 604 that slidably engages with the sliding ball 405 is fixed to the top of the positioning cylinder 603. The inclined plane has an angle of 15°-30° to ensure that the sliding ball 405 can effectively drive the positioning component 2 to rotate circumferentially when sliding along the inclined plane, while avoiding jamming due to excessive angle. An annular plate 605 is fixed to the inner wall of the positioning cylinder 603. Several grooves 606 are opened on the inner wall of the annular plate 605. Several U-shaped plates 607 are fixed to the inner wall of the positioning cylinder 603 above the annular plate 605. An I-shaped slider 608 is slidably fitted on the inner wall of the U-shaped plate 607. A lower extension rod 609 is fixed to the bottom of the I-shaped slider 608. A contact ball 610 is fixed to the bottom of the lower extension rod 609. The contact ball 610 slides in sequence with the grooves 606 and the annular plate 605. An elastic spring 611 is fixed between the I-shaped slider 608 and the U-shaped plate 607. An extension horizontal plate 612 is fixed to the side of the I-shaped slider 608. A clamping plate 613 is fixed to the side of the extension horizontal plate 612.

[0045] The specific application of this embodiment is as follows: This device needs to perform overpressure testing on the disc spring to be tested. First, the bottom of the disc spring to be tested is positioned and clamped, so that the disc spring to be tested is placed at the top center position of the worktable 301. Then, the lower pressing member 4 is driven to move downward, so that the sliding ball 405 in the lower pressing member 4 begins to slide from the high position of the annular inclined platform 604 to the low position of the annular inclined platform 604, thereby driving the entire positioning assembly 2 to rotate circumferentially between the two arc rings 303 (before the circumferential rotation, the semi-circular grooves 502 respectively opened on the inner wall of the two semi-circular rings 501 are rotated with the two arc rings 303, and then the connecting ear plates 503 on the two arc rings 303 are connected by external bolts). The ring 5 is rotatably connected to the two arc-shaped rings 303. Then, the two insertion holes 602 through the top of the insertion ring 601 are respectively inserted into the circumferential surfaces of the two insertion rods 504. The positioning component 6 is then connected and fixed via a threaded connection between the external nut and the insertion rod 504. This allows the entire positioning assembly 2 to be rotatably connected to the inner top of the detection assembly 1 (for later overpressure testing of the disc spring to be tested). The annular plate 605 fixed to the inner wall of the positioning cylinder 603 and the grooves 606 on the inner wall of the annular plate 605 slide against the contact balls 610, ultimately causing the contact balls 610 to slide from the inner wall of the grooves 606 to the annular plate 603. The inner wall of 05 causes the elastic spring 611, which is connected and fixed between the I-shaped slider 608 and the U-shaped plate 607, to be stretched. This causes the I-shaped sliders 608 to slowly slide in a straight line away from the inner wall of the U-shaped plates 607. This eventually causes the clamping plates 613 to move radially in a straight line synchronously inside the annular plate 605 until the inner wall of the clamping plates 613 is in contact with the peripheral side of the disc spring to be tested. Then, the sliding ball 405 in the pressing member 4 begins to slide from the low position of the annular inclined platform 604 into the top of the sliding member 7, thereby pressing the sliding member 7 downward. At this time, since the sliding member 7 is slidably fitted on the testing member 3, the sliding ball 405 in the pressing member 4... 05 During the subsequent descent, the entire positioning assembly 2 stops circumferentially between the two arc-shaped rings 303. Several clamping plates 613 stop synchronously in radial linear motion within the annular plate 605 (when the clamping plates 613 stop synchronously in radial linear motion within the annular plate 605, the inner walls of the clamping plates 613 are in contact with the circumferential surface of the disc spring to be tested). This allows for initial clamping and positioning of the bottom and overpressure detection of the disc spring after circumferential clamping and positioning. The detection data during the overpressure detection process is transmitted to the display screen in the controller via the pressure sensor 402 (during the transmission of data from the pressure sensor 402 to the display screen in the controller, both the pressure sensor 402 and the controller are existing technologies).The specific data transmission process and installation connection method between the two are not elaborated here, and the final result is displayed in numerical form. Throughout the process, the circumferential positioning and clamping action is completed during the overpressure detection process, preventing circumferential back-and-forth and left-and-right swaying caused by the spring's own elasticity during subsequent overpressure testing. This reduces detection errors during the overpressure detection process and improves the overall data detection effect.

[0046] Example 2, please refer to Figure 1-12This second embodiment is an improvement on the first embodiment as follows: Specifically, two symmetrical arc-shaped springs 614 are fixed to the outer wall of the positioning cylinder 603, and each of the ends of the two arc-shaped springs 614 is fixed with a sleeve 615 that fits into the circumferential side of the connecting column 304; the top of the positioning cylinder 603 is provided with a downwardly extending annular semi-groove 616; the sliding member 7 includes a semi-circular sliding plate 701 that slides into the annular semi-groove 616, and a semi-circular contact pressure plate 702 that slides into the top of the semi-circular sliding plate 701 and fits into the sliding ball 405. The diameter of the sliding ball 405 is smaller than the inner diameter of the annular semi-groove 616, and the side of the semi-circular contact pressure plate 702 is... The worktable 301 has a chamfered design, and several return springs 703 are fixed to the bottom of the semi-circular slide plate 701 and the annular semi-groove 616. An inwardly extending groove 306 is provided on the side of the worktable 301. Two symmetrical moving blocks 307 are slidably fitted inside the groove 306. A guide rod 323, which slides through and engages with the two moving blocks 307, is fixed inside the groove 306. A U-shaped clamping plate 308 is fixed to the top of each moving block 307 below the clamping plate 613. A first pin 309 is fixed to the bottom of each moving block 307 inside the worktable 301. A U-shaped base plate 3 is fixed to the inner wall of the worktable 301 below the first pin 309. 10. A sliding rail 311 is slidably fitted inside the U-shaped base plate 310. Two symmetrical second pins 312 are fixed to the top of the sliding rail 311. A rotating arm 313 is rotatably fitted between the second pins 312 and the first pin 309. A threaded rod 314 extending into the U-shaped base plate 310 is rotatably fitted through one outer side of the worktable 301. (The threaded rod 314 adopts a self-locking trapezoidal thread to prevent the sliding rail 311 from being accidentally displaced during the inspection process.) The threaded rod 314 is rotatably connected to the sliding rail 311 by threads. A first limiting ring 315 is fixed to the circumferential side of the threaded rod 314 and fits against one outer side of the worktable 301. A second limiting ring 316 is fixed to the side of the threaded rod 314 and fits against the inner wall of the U-shaped base plate 310; two symmetrical positioning posts 317 are fixed to the top of the workbench 301, and a top plate 318 is inserted between the two positioning posts 317. Two symmetrical insertion positioning cylinders 319 are connected to the top of the top plate 318, and the two insertion positioning cylinders 319 are respectively inserted and fixed to the two positioning posts 317; a through hole 320 is opened through the top of the top plate 318, and a telescopic cylinder 321 is fixed to the top plate 318. The telescopic end of the telescopic cylinder 321 is located below the top plate 318 and a second connecting flange 322 is fixed to the first connecting flange 401.

[0047] The specific application of this embodiment two is as follows: Before performing overpressure testing on the disc spring, the bottom end of the disc spring to be tested is placed inside the two U-shaped clamps 308 for preliminary positioning and clamping. After the preliminary positioning and clamping is completed, the threaded rod 314 is rotated, which drives the sliding rail 311 connected to it to move away from one outer side of the worktable 301 inside the U-shaped base plate 310. This drives the rotating arm 313, which is rotated between the second pin 312 and the first pin 309, to expand synchronously away from each other. This drives the two moving blocks 307 to make linear movements away from each other inside the extension groove 306, and finally makes the two U-shaped clamps 308 fixed at the top of the two moving blocks 307 gradually approach the bottom end of the disc spring to be tested. This performs preliminary clamping and positioning on the disc spring to be tested, preventing the bottom end of the disc spring to be tested from shaking or shifting during the overpressure testing, thereby improving the overpressure testing effect of the disc spring to be tested.

[0048] When this device performs overpressure testing on the disc spring after clamping and positioning, as the telescopic cylinder 321 descends, the second connecting flange 322 fixed to the telescopic end of the telescopic cylinder 321 moves downward synchronously, causing the sliding ball 405 to gradually slide from the high position of the annular inclined platform 604 to the low position of the annular inclined platform 604 (during the process of the sliding ball 405 gradually sliding from the high position of the annular inclined platform 604 to the low position of the annular inclined platform 604, the entire positioning assembly 2 rotates circumferentially inside the detection assembly 1 to perform circumferential clamping and positioning of the disc spring to be tested, preventing circumferential shaking of the disc spring during overpressure testing), and finally slides from the low position of the annular inclined platform 604 past the chamfered part on the side of the semicircular contact pressure plate 702 to the top of the semicircular contact pressure plate 702 (the sliding ball 405 slides from the high position of the annular inclined platform 604 to the low position of the annular inclined platform 604). After sliding to the top of the semicircular contact pressure plate 702, the semicircular contact pressure plate 702 moves downward under the squeezing force of the sliding ball 405. At this time, the circumferential rotation process of the entire positioning component 2 inside the detection component 1 stops, the circumferential positioning and clamping process of the disc spring to be tested ends, and it will not affect the continued downward overpressure process of the telescopic cylinder 321. Then the telescopic cylinder 321 continues to descend and gradually generates a downward pressure on the top of the semicircular contact pressure plate 702, thereby compressing the several reset springs 703 connected and fixed between the semicircular slide plate 701 and the annular semi-groove 616, driving the semicircular slide plate 701 to slowly move downward inside the annular semi-groove 616, thereby performing overpressure detection on the disc spring to be tested, so that the detection data during the overpressure detection process is transmitted to the display panel in the controller through the pressure sensor 402, thereby completing the overpressure detection process of the disc spring to be tested after positioning and fixing.

[0049] As the sliding ball 405 gradually slides from the inclined plane of the annular inclined plane 604 to its lowest point, the positioning component 2 rotates circumferentially inside the detection component 1. At this time, the arc-shaped spring 614, fixedly connected between the positioning cylinder 603 and the sleeve cylinder 615, is stretched synchronously until the disc spring to be tested completes the overpressure detection. Then, the telescopic cylinder 321 begins to retract, causing the sliding ball 405 to gradually slide from the top of the semi-circular contact plate 702 to the lower position of the inclined plane of the annular inclined plane 604. In subsequent processes, the telescopic cylinder... Cylinder 321 continues to contract, and sliding ball 405 begins to slide from the lower position of the inclined plane 604 to the higher position of the inclined plane 604. It is fixedly connected between positioning cylinder 603 and sleeve 615, and the stretched arc spring 614 begins to reset. At this time, under the reaction force of arc spring 614, positioning component 2 rotates in the opposite direction inside positioning component 2, thereby performing a circumferential positioning clamping release operation on the disc spring to be tested, so as to continuously perform overpressure testing on other disc springs to be tested.
