Abstract
Description
Technical Field
[0001] This utility model relates to the field of flange processing technology, specifically a strength testing device for processing lightweight composite flanges. Background Technology
[0002] A flange, also called a flange plate or flange, is a part used to connect shafts, pipe ends, or on equipment inlets and outlets for connecting two pieces of equipment.
[0003] A search revealed a strength testing device for flange production and processing, with publication number CN220932603U. In use, the servo motor can be activated to move the vertical rod inwards, causing the clamp to adhere to the flange surface, thus securing and fixing the flange and preventing displacement during strength testing.
[0004] However, in the aforementioned application, when clamping a thin flange, if the servo motor does not stop in time, the fixture may apply excessive clamping force, causing the flange to undergo plastic deformation or even be damaged, affecting the accuracy of subsequent tests. Utility Model Content
[0005] The purpose of this invention is to provide a strength testing device for the processing of lightweight composite flanges, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a strength testing device for processing lightweight composite flanges, comprising a workbench, wherein the surface of the workbench is provided with stabilizing components and protective components;
[0007] Linkage rod, used to drive the slide rod to move synchronously;
[0008] The slide bar is used to drive the locking block to move synchronously;
[0009] The card slot is used to cooperate with the card block to achieve limit positioning.
[0010] Preferably, the stabilizing component includes a connecting frame fixed to the bottom of the workbench. A motor is rotatably connected to the outer surface of the connecting frame, and the output shaft of the motor passes through the connecting frame. A circular plate is rotatably connected to the bottom of the workbench, and a worm gear is fixed to the bottom of the circular plate. A worm is rotatably connected to the inner side of the connecting frame, and the worm gear meshes with the worm. A movable hole is formed on the outer surface of the circular plate, and a long rod abuts against the inner wall of the movable hole. A through hole is formed on the outer surface of the workbench, and the top of the long rod passes through the through hole. A movable block is fixed to the top of the long rod and slidably connected to the top of the workbench. A slider is slidably connected to the inner wall of the movable block, and a clamping plate is fixed to the outer surface of the slider. A spring is fixed to the end of the slider away from the clamping plate, and the end of the spring away from the slider is fixed to the inner wall of the movable block. Transmission components are provided on the surfaces of the worm and the output shaft of the motor, allowing the worm and worm gear to rotate. The inner wall of the movable hole abuts against the surface of the long rod. The long rod drives the moving block to move radially within the through hole, driving the clamping plate to clamp the flange, which facilitates testing.
[0011] Preferably, the transmission component includes a groove, the output shaft of the motor extends into the groove, the output shaft of the motor passes through and is slidably connected to a first transmission plate, the output shaft of the motor passes through and is fixed to a second transmission plate, a second spring is fixed to the outer surface of the first transmission plate, the end of the second spring away from the first transmission plate is fixed to the outer surface of the second transmission plate, an abutment block is fixed to the side of the first transmission plate away from the second spring, and an abutment groove is formed on the inner wall of the groove. When the circular plate cannot rotate, the worm gear and worm stop rotating, and the abutment block slips against the abutment groove, protecting the motor from damage.
[0012] Preferably, one end of the linkage rod is hinged to the side of the clamping plate near the slider, and the end of the linkage rod away from the clamping plate is hinged to a slide rod. A stabilizing plate is fixed to the outer surface of the moving block. The side of the slide rod away from the linkage rod is slidably connected to the outer surface of the stabilizing plate. A locking block is slidably connected to the inner wall of the slide rod. A spring three is fixed to the top of the locking block, and the top of the spring three is fixed to the top of the inner wall of the slide rod. A through hole two is opened on the outer surface of the worktable. The bottom of the slide rod and the locking block penetrates the worktable. A slot is opened on the top of the circular plate. An inclined surface one is opened on the side of the locking block away from the spring three, and an inclined surface two is opened on the side of the locking block away from the inclined surface one. When the motor continues to work, the slider slides into the moving block, compressing the spring one, while the clamping plate moves closer to the stabilizing plate. At this time, the linkage rod flips, causing the slide rod and the locking block to move down synchronously. When the bottom of the locking block contacts the top of the circular plate, the locking block retracts into the slide rod and compresses the spring three. When the locking block aligns with the slot, the spring three is released, pushing the locking block into the slot. At this point, the plane of the clamping block abuts against the inner wall of the clamping slot, restricting the movement of the circular plate and preventing the clamping plate from over-clamping the flange. This avoids deformation caused by excessive clamping force due to the motor not stopping in time, ensuring test accuracy. When the motor is turned on in reverse, the circular plate reverses, causing the inner wall of the clamping slot to abut against the inclined surface of the clamping block. The clamping block retracts into the slide rod, releasing the restriction, and the clamping plate can then release the flange normally.
[0013] Preferably, the movable hole is arc-shaped, and when it rotates with the circular plate, it causes the long rod and the moving block to move radially synchronously through contact.
[0014] Preferably, both the contact block and the contact groove are hemispherical, which allows them to slip when the worm gear cannot rotate, thus preventing damage to the motor.
[0015] Compared with the prior art, this utility model provides a strength testing device for the processing of lightweight composite flanges, which has the following beneficial effects:
[0016] 1. This strength testing device for lightweight composite flange processing, through the set protective components, when the clamping plate clamps the flange, the motor continues to work, the clamping plate moves closer to the stabilizing plate, at this time the connecting rod flips, driving the sliding rod and the locking block to move down synchronously, and the locking block is pushed into the locking groove by the spring. At this time, the plane of the locking block abuts against the inner wall of the locking groove, limiting the circular plate and preventing the clamping plate from over-clamping the flange, avoiding deformation caused by excessive clamping force due to the motor not stopping in time, and ensuring the accuracy of the test.
[0017] 2. This strength testing device for lightweight composite flange processing utilizes a stabilizing component. When the motor rotates forward, the surface of the contact block contacts the inner wall of the contact groove, driving the worm and worm wheel to rotate synchronously. At this time, the inner wall of the movable hole contacts the surface of the long rod, causing the long rod to drive the moving block to move radially within the through hole, driving the clamping plate to clamp the flange for subsequent testing. When the circular plate cannot rotate, the worm wheel and worm stop rotating, and the contact block slips against the contact groove. Spring 2 causes the transmission plate 1 to reciprocate, thus protecting the motor from damage and preventing burnout. Attached Figure Description

[0026] like Figures 1-7As shown, this utility model provides a technical solution: a strength testing device for processing lightweight composite flanges, including a workbench 1, the surface of which is provided with a stabilizing component 2 and a protective component 3; a connecting rod 30, a sliding rod 31, a locking block 32, a spring 33, a slot 34, a through hole 35, an inclined surface 36, an inclined surface 37, and a stabilizing plate 38.
[0027] One end of the linkage rod 30 is hinged to the side of the clamping plate 201 near the slider 28, and the other end of the linkage rod 30 away from the clamping plate 201 is hinged to the slide rod 31. The outer surface of the moving block 27 is fixed with a stabilizing plate 38. The side of the slide rod 31 away from the linkage rod 30 is slidably connected to the outer surface of the stabilizing plate 38. The inner wall of the slide rod 31 is slidably connected with a locking block 32. The top of the locking block 32 is fixed with a spring 33. The top of the spring 33 is fixed to the top of the inner wall of the slide rod 31. The outer surface of the worktable 1 has a through hole 2 35. The bottom of the slide rod 31 and the locking block 32 penetrate the worktable 1. The top of the circular plate 24 has a slot 34. The side of the locking block 32 away from the spring 33 has an inclined surface 1 36. The side of the locking block 32 away from the inclined surface 1 36 has an inclined surface 2 37. When the motor 22 works continuously, the slider 28 moves into the moving block 27, compressing the spring 1 200. At the same time, the clamping plate 201 moves closer to the stabilizing plate 38. At this time, the linkage 30 flips, causing the slide bar 31 and the locking block 32 to move down synchronously. When the bottom of the locking block 32 contacts the top of the circular plate 24, the locking block 32 retracts into the slide bar 31 and compresses the spring 33. When the locking block 32 is aligned with the slot 34, the spring 33 is released, pushing the locking block 32 into the slot 34. At this time, the plane of the locking block 32 abuts against the inner wall of the slot 34, restricting the movement of the circular plate 24, thereby preventing the clamping plate 201 from over-clamping the flange and avoiding flange deformation caused by excessive clamping force due to the motor 22 not stopping in time, ensuring the accuracy of subsequent tests. When the motor 22 is turned on to reverse, the circular plate 24 reverses. At this time, the inner wall of the slot 34 abuts against the inclined surface 36 and the inclined surface 37, allowing the locking block 32 to enter the slide bar 31 without affecting the normal reverse rotation of the circular plate 24, thus allowing the clamping plate 201 to release the flange normally.
[0028] The stabilizing component 2 includes a connecting frame 20, which is fixed to the bottom of the workbench 1. A motor 22 is rotatably connected to the outer surface of the connecting frame 20, and the output shaft of the motor 22 passes through the connecting frame 20. A circular plate 24 is rotatably connected to the bottom of the workbench 1, and a worm gear 23 is fixed to the bottom of the circular plate 24. A worm 21 is rotatably connected to the inner side of the connecting frame 20, and the worm gear 23 meshes with the worm 21. A movable hole 25 is opened on the outer surface of the circular plate 24, and a long rod 26 abuts against the inner wall of the movable hole 25. A through hole 202 is opened on the outer surface of the workbench 1, and the top of the long rod 26 passes through the through hole 202. A movable block 27 is fixed to the top of the long rod 26 and is slidably connected to the top of the workbench 1. A slider 28 is slidably connected to the inner wall of the movable block 27. A clamping plate 201 is fixed to the outer surface of the slider 28, and a spring 200 is fixed to the end of the slider 28 away from the clamping plate 201. One end of block 28 is fixed to the inner wall of movable block 27. The worm gear 21 and the output shaft of motor 22 are provided with transmission components 29. Transmission component 29 includes groove 290. The output shaft of motor 22 extends into groove 290. Transmission plate 291 is slidably connected through the output shaft of motor 22. Transmission plate 292 is fixed through the output shaft of motor 22. Spring 293 is fixed on the outer surface of transmission plate 291. The end of spring 293 away from transmission plate 291 is fixed on the outer surface of transmission plate 292. Abutment block 294 is fixed on the side of transmission plate 291 away from spring 293. Abutment groove 295 is provided on the inner wall of groove 290. Movable hole 25 is arc-shaped. Abutment block 294 and abutment groove 295 are both hemispherical. When motor 22 rotates forward, the surface of abutment block 294 abuts against the inner wall of abutment groove 295, driving worm gear 21 and worm wheel 23 to rotate synchronously. At this time, the inner wall of the movable hole 25 abuts against the surface of the long rod 26, causing the long rod 26 to drive the moving block 27 to move radially within the through hole 202, while simultaneously driving the clamping plate 201 to clamp the flange. When the circular plate 24 cannot rotate, the worm gear 23 and worm 21 stop rotating, and the contact block 294 slips against the contact groove 295. Through the spring 293, the transmission plate 291 reciprocates, thereby protecting the motor 22 from damage and preventing it from burning out.
[0029] When a strength test is required on the flange, the flange is placed on top of the workbench 1. The motor 22 is then turned on and rotates forward. The surface of the contact block 294 contacts the inner wall of the contact groove 295, causing the worm gear 21 and worm wheel 23 to rotate synchronously. At this time, the inner wall of the movable hole 25 contacts the surface of the long rod 26, causing the long rod 26 to move the moving block 27 radially within the through hole 202. Simultaneously, this moves the clamping plate 201, clamping the flange. The motor... Machine 22 continues to operate. At this time, slider 28 moves into moving block 27, spring 200 is compressed, and clamping plate 201 moves closer to stabilizing plate 38. At this time, connecting rod 30 flips, causing slider 31 and locking block 32 to move downwards synchronously. When the bottom of locking block 32 contacts the top of circular plate 24, locking block 32 moves into slider 31, spring 33 is compressed. When locking block 32 is parallel to locking slot 34, spring 33 is released, thus driving locking block 32 into locking slot 34. At this time, locking block 32... When the surfaces away from inclined plane 36 and inclined plane 37 come into contact with the inner wall of the slot 34, the circular plate 24 is limited. At this time, the clamping plate 201 cannot continue to clamp the flange, thus avoiding excessive clamping force caused by failure to stop the motor 22 in time, which could deform the flange and affect subsequent testing. At the same time, when the circular plate 24 cannot rotate, the worm gear 23 and worm 21 cannot continue to rotate, and the contact block 294 slips with the contact groove 295. Through the spring 293, the transmission plate 291 reciprocates. This will not affect the normal operation of motor 22, thus preventing motor 22 from burning out. At this time, normal testing can be carried out. When it is necessary to remove the flange, turn on motor 22 to reverse and turn circular plate 24 to reverse. At this time, the inner wall of slot 34 abuts against inclined surface 36 and inclined surface 37, which allows the locking block 32 to enter the slide bar 31. This will not affect the normal reverse rotation of circular plate 24, which allows clamping plate 201 to properly loosen the flange for easy removal. At this time, spring 200 is released, driving clamping plate 201 to reset for easy use next time.
[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
