Description

Technical Field

[0001] The present invention relates to the technical field of gasket detection, and in particular to a tool and method for detecting the compressive performance of a rubber plastic gasket. Background Art

[0002] Rubber plastic gaskets have the properties of acid and alkali resistance, cold and heat resistance, and aging resistance. They can be directly cut into sealing gaskets of various shapes and are widely used in the pharmaceutical, electronic, chemical, antistatic, flame retardant, food and other industries. Rubber plastic gaskets can be manufactured by molding or punched by vulcanized rubber sheets. They can be widely used in various mechanical equipment to play the role of gasket, seal, buffer, etc. Rubber plastic gaskets are formed by processing rubber, plastic, and nanomaterials.

[0003] Publication number CN216208128U discloses a tool for testing the compressive performance of aramid oil-resistant rubber gaskets, comprising a base, a pressure detection head provided on the top of the base, a vertical plate provided on one side of the pressure detection head, a pressure gauge connected to the other side of the pressure detection head, the bottom end of the vertical plate and the pressure gauge are both fixed to the top of the base, and a tray provided on the top of the pressure detection head. The above application installs the aramid oil-resistant rubber gasket in the clamping mechanism of the tray, adjusts the expansion distance of the arc pressure plate by rotating the adjustment rod according to the part of the gasket to be tested, so that the arc pressure plate corresponds to the testing part of the gasket, and then pushes the arc pressure plate by the electric push rod to squeeze the gasket, so as to be suitable for the compressive performance testing of different parts of the gasket, avoids the problem that the pressure is relatively uniform when the gasket is subjected to the pressure test as a whole, and it is difficult to reflect the local compressive performance of the gasket, thereby improving the accuracy of the gasket compressive performance testing.

[0004] Although the above-mentioned application and the prior art can improve the accuracy of the gasket compression resistance test, when the above-mentioned application and the prior art perform compression resistance test on the rubber plastic gasket, since the rubber plastic gasket needs to be squeezed with the test head, the rubber plastic gasket will be adsorbed on the bottom of the test head, thereby affecting the recovery of the rubber plastic gasket. In order to prevent the rubber plastic gasket from being adsorbed on the bottom of the test head, a lubricant is usually sprayed on the bottom of the test head. Since the test head needs to squeeze the rubber plastic gasket, the pores of the rubber plastic gasket will expand during the squeezing process, and the lubricant will enter the interior of the rubber plastic gasket, thereby affecting the subsequent normal use. In order to prevent the lubricant from entering the interior, it is usually necessary to block the bottom. When a new rubber plastic gasket is tested, the blocking object needs to be replaced. This process will consume a lot of time, thereby affecting the compression resistance test efficiency of the rubber plastic gasket. Therefore, the present invention proposes a compression resistance test tool and method based on rubber plastic gaskets. Summary of the Invention

[0005] (1) Technical problems solved

[0006] In response to the shortcomings of the prior art, the present invention provides a tool and method for testing the compressive performance of rubber plastic gaskets, which has the advantages of preventing adhesion, avoiding intrusion and facilitating replacement. It solves the problem that when the rubber plastic gasket is subjected to compression testing in the above-mentioned application and the prior art, the rubber plastic gasket needs to be squeezed with the detection head, so the rubber plastic gasket will be adsorbed on the bottom of the detection head, thereby affecting the recovery of the rubber plastic gasket. In order to prevent the rubber plastic gasket from being adsorbed on the bottom of the detection head, a lubricant is usually sprayed on the bottom of the detection head. Since the detection head needs to squeeze the rubber plastic gasket, the pores of the rubber plastic gasket will expand during the squeezing process, and the lubricant will enter the interior of the rubber plastic gasket, thereby affecting subsequent normal use. In order to prevent the lubricant from entering its interior, it is usually necessary to block its bottom. When a new rubber plastic gasket is tested, the blocking object needs to be replaced, and this process consumes a lot of time, thereby affecting the efficiency of the compression testing of the rubber plastic gasket.

[0028] (3) Beneficial effects

[0029] Compared with the prior art, the present invention provides a tool and method for testing the compressive performance of rubber plastic gaskets, which has the following beneficial effects:

[0030] 1. The tooling and method for testing the compressive performance of the rubber plastic gasket, through the coordinated use of the pressure component and the lubricating component, starts the pressure cylinder, and the pressure cylinder drives the slide plate to move through the pressure column, so that the slide plate stretches the first pull rope through the sliding plate, and the first pull rope drives the first rotating rod to rotate through the first pay-off wheel, so that the storage wheel stretches the second pull rope, and the second pull rope drives the second rotating rod to rotate through the second pay-off wheel during the storage process, so that the second rotating rod drives the rotating rod to rotate through the transmission mechanism, and then the infusion tube gradually rotates to the bottom of the pressure block, and when the infusion tube rotates, the suction pump is started, and the suction pump transports the lubricant in the liquid tank to the liquid outlet pipe through the liquid inlet pipe, and then sprays the bottom of the pressure block through the atomizing nozzle, so that the lubricant adheres to the bottom of the pressure block, and then when the pressure block squeezes the rubber plastic gasket, the rubber plastic gasket will not stick to the bottom of the pressure block, thereby achieving the effect of preventing adhesion.

[0031] 2. The tooling and method for testing the compressive performance of rubber-plastic gaskets use a pressure component in conjunction with a protective component. When the slide plate is descending, the slide plate drives the pressure block to gradually descend, causing the bottom of the pressure block to gradually move toward the surface of the protective film. As the pressure block continues to descend, the pressure block drives the film roller to rotate through the protective film, causing the protective film to wrap the bottom of the pressure block. As the pressure block squeezes the rubber-plastic gasket, the lubricant at the bottom of the pressure block will not enter the interior of the rubber-plastic gasket because it is wrapped by the protective film, thereby achieving the effect of avoiding intrusion.

[0032] 3. The tooling and method for testing the compressive performance of rubber and plastic gaskets, through the coordinated use of a pressure component and a film changing component, when the pressure on the rubber and plastic gasket is completed, the pressure cylinder drives the slide plate to rise through the pressure column, so that the slide plate drives the telescopic rod to rise through the support block, and during the rising process of the telescopic rod, the air inside the fixed cylinder is transported to the inside of the air guide frame through the air guide pipe via the sealing plate. As the air inside the air guide frame continues to increase, the sealing plate drives the beveled tooth plate to move and the spring is stretched, and the beveled tooth plate drives the ratchet to rotate during the movement, so that the film collecting rod drives the film collecting roller to rotate, and then the film collecting roller rewinds the used protective film, and when the slide plate drops again, the one-way valve opens so that the spring is no longer stretched by the sealing plate and returns to its original state, and then the beveled tooth plate returns to its original state, and the beveled tooth plate deforms at the bottom beveled teeth when it recovers, so that the beveled tooth plate does not drive the ratchet to reverse, thereby achieving the effect of easy replacement.

[0033] Other features and advantages of the present invention will be described in the following description, and part of them will become obvious from the description, or will be understood by practicing the present invention.

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0049] In the embodiments of the present application, any device or element referred to or implied must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the embodiments of the present application. In the description of the embodiments of the present application, the meaning of "plurality" is two or more, unless otherwise specifically specified.

[0050] For specific embodiment 1, please refer to Figures 1 to 3 A compressive performance testing tool based on a rubber plastic gasket includes: a testing platform 1 and a plane detector arranged on the top of the testing platform 1.

[0051] The placement table 12 is fixedly connected to the top of the detection table 1. The two sides of the top of the detection table 1 are fixedly connected to the movable table 13. The opposite surfaces of the two movable tables 13 are fixedly connected to the support plates 131. The surface of the detection table 1 is provided with a control panel 11;

[0052] A pressure assembly 2 is provided on the top of the testing platform 1 and is used to apply pressure to the rubber plastic gasket. The pressure assembly 2 includes a pressure cylinder 21 fixedly connected to the top of the support plate 131. The output end of the pressure cylinder 21 is differentially connected to a pressure column 211. The bottom of the pressure column 211 is fixedly connected to a slide 22. The bottom of the slide 22 is fixedly connected to a pressure block 221.

[0053] The lubricating component 3 is provided on the surface of the slide plate 22 and is used to spray lubricant on the bottom of the pressure block 221 to prevent the rubber plastic gasket from being adhered to the bottom of the pressure block 221 after being squeezed;

[0054] The protective component 4 is provided inside the movable platform 13 and is used to prevent the lubricant sprayed on the bottom of the pressure block 221 from directly contacting the rubber plastic gasket, thereby causing damage to the rubber plastic gasket;

[0055] The membrane replacement component 5 is arranged inside the movable platform 13 and is used to replace the protective component 4 after use, thereby preventing the protective component 4 from being damaged and affecting subsequent use;

[0056] It should be noted that a limiting mechanism is provided on the surface of the placement platform 12. The limiting mechanism includes a storage tube fixedly connected to the interior of the placement platform 12. An elastic member is fixedly connected to the interior of the storage tube, and an extension tube is slidably connected to the interior of the storage tube. The extension tube is located on the top of the placement platform 12. The rubber plastic gasket to be tested can be placed on the surface of the extension tube.

[0057] When a compression test is required for a rubber plastic gasket, the rubber plastic gasket to be tested is placed in the center of the top of the placement table 12, and then the pressure cylinder 21 is started through the control panel 11. The pressure cylinder 21 drives the slide 22 to move through the pressure column 211, so that the slide 22 drives the pressure block 221 to move toward the position of the placement table 12, and then the pressure block 221 squeezes the rubber plastic gasket. After the squeezing is completed, the pressure block 221 is restored to its initial state through the control panel 11, and then the recovery of the squeezed rubber plastic gasket is observed through the plane detector, and the plane detector transmits the observed situation to the inside of the control panel 11;

[0058] For specific embodiment 2, please refer to Figures 1 to 3 According to the compressive performance testing tool based on rubber plastic gasket provided in the first embodiment, this embodiment provides a further technical solution:

[0059] The lubrication assembly 3 includes a liquid tank 31 fixedly connected to the top of the slide 22 and a suction pump 32 fixedly connected to the top of the slide 22. The suction end of the suction pump 32 is fixedly connected to the liquid tank 31 through a liquid inlet pipe 321. The output end of the suction pump 32 is fixedly connected to a liquid outlet pipe 322. A section of the liquid outlet pipe 322 away from the suction pump 32 is fixedly connected to a liquid infusion pipe 323. The top of the liquid infusion pipe 323 is fixedly connected to a plurality of atomizing nozzles 324. The lubrication assembly 3 also includes a sliding plate 33 fixedly connected to one side of the slide 22 and a first rotating rod 34 rotatably connected to the inside of one of the moving platforms 13. The surface of the first rotating rod 34 is fixedly connected to a first pay-off wheel 341 and a storage wheel 343. The surface of the first pay-off wheel 341 is fixedly connected to A first pull rope 342 is connected, and one end of the first pull rope 342 away from the first pay-off wheel 341 is fixedly connected to the top of the sliding plate 33. The lubrication assembly 3 also includes a protective shell 36 fixedly connected to the top of the slide plate 22 and a guide rod 35 rotatably connected to the bottom of the support plate 131. The interior of the protective shell 36 is rotatably connected to a rotating rod 361, and the bottom of the rotating rod 361 is fixedly connected to the top of the infusion tube 323. The interior of the protective shell 36 is rotatably connected to a second rotating rod 362, and the surface of the second rotating rod 362 is fixedly connected to the second pay-off wheel 363. The surface of the second pay-off wheel 363 is fixedly connected to a second pull rope 364, and the end of the second pull rope 364 away from the second pay-off wheel 363 is fixedly connected to the surface of the storage wheel 343;

[0060] It should be noted that the control panel 11 is electrically connected to the plane detector, the pressure cylinder 21 and the suction pump 32. The opening and closing of the plane detector, the pressure cylinder 21 and the suction pump 32 are controlled by the control commands inside the control panel 11. A solenoid valve is provided inside the atomizing nozzle 324, and a light sensor is provided on the surface of the solenoid valve. When the light sensor detects that the atomizing spray nozzle 324 is located at the bottom of the pressure block 221, the solenoid valve opens, thereby causing the atomizing nozzle 324 to spray the lubricant. The transmission mechanism 365 includes a driven bevel gear fixedly connected to the top of the rotating rod 361 and a driving bevel gear fixedly connected to one end of the second rotating rod 362. The driving bevel gear and the driven bevel gear are meshed for transmission.

[0061] When it is necessary to prevent the rubber plastic gasket from adhering to the bottom of the pressure block 221 after being squeezed, the pressure cylinder 21 drives the slide plate 22 to move through the pressure column 211, so that the slide plate 22 stretches the first pull rope 342 through the sliding plate 33, and the first pull rope 342 drives the first rotating rod 34 to move through the first pay-off wheel 341, so that the storage wheel 343 stretches the second pull rope 364. During the storage process, the second pull rope 364 drives the second rotating rod 362 to rotate through the second pay-off wheel 363, so that the second rotating rod 362 drives the rotating rod 361 to rotate through the transmission mechanism 365, and the rotating rod 361 drives the infusion tube 323 to rotate, so that the infusion tube 323 gradually rotates to the bottom of the pressure block 221 When the infusion tube 323 rotates, the suction pump 32 is started, and the suction pump 32 delivers the lubricant inside the liquid tank 31 to the liquid outlet pipe 322 through the liquid inlet pipe 321, and then sprays the lubricant on the bottom of the pressure block 221 through the atomizing nozzle 324, so that the lubricant adheres to the bottom of the pressure block 221, and then when the pressure block 221 squeezes the rubber plastic gasket, the rubber plastic gasket will not stick to the bottom of the pressure block 221, thereby preventing the pressure block 221 from driving the rubber plastic gasket to rise when the pressure block 221 rises, so that the plane detector can better observe the recovery of the rubber plastic gasket, thereby making the compression test result of the rubber plastic gasket more accurate;

[0062] For specific example three, please refer to Figures 1 to 3 According to the compressive performance testing tool based on rubber plastic gasket provided in the second embodiment, this embodiment provides a further technical solution:

[0063] The protective assembly 4 includes a roller rod 41 rotatably connected to the inside of one of the movable platforms 13, a film roller 411 is fixedly connected to the surface of the roller rod 41, a protective film 412 is provided on the surface of the film roller 411, and the protective film 412 is located on the top of the placement platform 12. The protective assembly 4 also includes a drive shell 42 fixedly connected to the inside of the other movable platform 13, a film collection rod 421 is rotatably connected to the inside of the drive shell 42, a film collection roller 422 is fixedly connected to the surface of the film collection rod 421, and an end of the protective film 412 away from the film roller 411 is fixedly connected to the surface of the film collection roller 422;

[0064] When it is necessary to prevent the lubricant at the bottom of the pressure block 221 from penetrating into the interior of the rubber plastic gasket, when the slide plate 22 is in the process of descending, the slide plate 22 drives the pressure block 221 to gradually descend, so that the bottom of the pressure block 221 gradually moves toward the surface of the protective film 412. As the pressure block 221 continues to descend, the pressure block 221 drives the film roller 411 to rotate through the protective film 412, so that the protective film 412 wraps the bottom of the pressure block 221. As the pressure block 221 squeezes the rubber plastic gasket, the lubricant at the bottom of the pressure block 221 will not enter the interior of the rubber plastic gasket due to being wrapped by the protective film 412. Due to the dual use of the protective film 412 and the lubricant, the pressure block 221 can be separated from the protective film 412 first during the rising process, and the protective film 412 will not hinder the recovery of the rubber plastic gasket, thereby making the result of the pressure resistance test more accurate.

[0065] For specific example 4, please refer to Figures 1 to 3 According to the compressive performance testing tool based on rubber plastic gasket provided in the third embodiment, this embodiment provides a further technical solution:

[0066] The membrane changing assembly 5 includes a support block 51 fixedly connected to one end of the slide 22, a telescopic rod 511 fixedly connected to the top of the support block 51, a sealing disk 512 fixedly connected to the top of the telescopic rod 511, and a fixed cylinder 52 fixedly connected to the inside of the movable platform 13. A one-way valve 521 is provided on the surface of the fixed cylinder 52, and an air guide tube 522 is fixedly connected to the surface of the fixed cylinder 52. The sealing disk 512 is slidably connected to the inside of the fixed cylinder 52. The membrane changing assembly 5 also includes a fixed cylinder 52 fixedly connected to the drive The air guide frame 53 inside the dynamic housing 42 and the ratchet 54 fixedly connected to the surface of the film collecting rod 421, the end of the air guide tube 522 away from the fixed cylinder 52 is fixedly connected to the air guide frame 53, the interior of the air guide frame 53 is fixedly connected to a spring 531, the interior of the air guide frame 53 is slidably connected to a sealing plate 532, one end of the sealing plate 532 is fixedly connected to one end of the spring 531, and the end of the sealing plate 532 away from the spring 531 is fixedly connected to a beveled tooth plate 533, which meshes with the ratchet 54 for transmission;

[0067] It should be noted that the bevel teeth at the bottom of the bevel plate 533 and the ratchet 54 are both made of plastic. When the bevel plate 533 is housed within the gas cylinder 53, the bevel teeth at the bottom of the bevel plate 533 may deform, thereby preventing the bevel plate 533 from driving the ratchet 54 to reverse.

[0068] When the protective film 412 needs to be replaced after use, after the pressure on the rubber plastic gasket is completed, the pressure cylinder 21 drives the slide plate 22 to rise through the pressure column 211, so that the slide plate 22 drives the telescopic rod 511 to rise through the support block 51. During the rising process, the telescopic rod 511 transmits the air inside the fixed cylinder 52 through the air guide pipe 522 to the inside of the air guide frame 53 through the sealing plate 512. As the air inside the air guide frame 53 continues to increase, the sealing plate 532 drives the bevel gear plate 533 to move and causes the spring 531 to stretch, and the bevel gear plate 53 During the movement, the ratchet 54 is driven to rotate, causing the film-collecting rod 421 to drive the film-collecting roller 422 to rotate, thereby causing the film-collecting roller 422 to reel in the used protective film 412. When the slide plate 22 descends again, the one-way valve 521 opens, so that the spring 531 is no longer stretched by the sealing plate 532 and returns to its original state, thereby causing the beveled tooth plate 533 to return to its original state. When the beveled tooth plate 533 returns to its original state, the beveled teeth at the bottom of the beveled tooth plate 533 are deformed, thereby preventing the beveled tooth plate 533 from driving the ratchet 54 to reverse, and thus preventing the film-collecting roller 422 from driving the protective film 412 to reverse.

[0069] Specific embodiment 5, the present invention also provides a method for testing the compressive performance of a rubber plastic gasket, the method for testing the compressive performance of a rubber plastic gasket specifically comprising the following steps:

[0070] Step 1: Place the rubber plastic gasket to be tested on top of the placement table 12 so that the rubber plastic gasket is located in the middle of the placement table 12;

[0071] Step 2: When the rubber plastic gasket needs to be inspected, the pressure component 2 is started to make the pressure block 221 squeeze the top of the rubber plastic gasket. After the squeezing is completed, the pressure component 2 is restored to its initial state, and the restored state of the rubber plastic gasket is observed by a plane detector;

[0072] Step 3: During the descent of the pressure block 221, the pressure assembly 2 drives the lubricating assembly 3 to spray lubricant onto the bottom of the pressure block 221 to prevent the rubber plastic gasket from being squeezed and adhering to the bottom of the pressure block 221.

[0073] Step 4: As the pressure block 221 continues to descend, the pressure block 221 drives the protective component 4, so that the protective component 4 protects the bottom of the pressure block 221 to prevent the lubricant from contaminating the rubber plastic gasket;

[0074] Step 5: When the pressure component 2 returns to its initial state, the pressure component 2 drives the membrane replacement component 5 so that the membrane replacement component 5 replaces the protective component 4, thereby avoiding affecting subsequent normal detection due to damage to the protective component 4.

[0075] Working principle: When in use, the rubber plastic gasket to be tested is placed in the center of the top of the placement table 12, and then the pressure cylinder 21 is started through the control panel 11. The pressure cylinder 21 drives the slide plate 22 to move through the pressure column 211, so that the slide plate 22 drives the pressure block 221 to move toward the position of the placement table 12. When it is necessary to prevent the rubber plastic gasket from being squeezed and attached to the bottom of the pressure block 221, the pressure cylinder 21 drives the slide plate 22 to move through the pressure column 211, so that the slide plate 22 stretches the first pull rope 342 through the sliding plate 33, and the first pull rope 342 drives the first rotating rod 34 to move through the first pay-off wheel 341, so that the storage wheel 343 stretches the second pull rope 364, and the second pull rope 364 is pulled by the second pay-off wheel 341 during the storage process. The pulley 363 drives the second rotating rod 362 to rotate, so that the second rotating rod 362 drives the rotating rod 361 to rotate through the transmission mechanism 365, and the rotating rod 361 drives the infusion tube 323 to rotate, so that the infusion tube 323 gradually rotates to the bottom of the pressure block 221. When the infusion tube 323 rotates, the suction pump 32 is started, and the suction pump 32 delivers the lubricant inside the liquid tank 31 to the liquid outlet pipe 322 through the liquid inlet pipe 321, and then sprays the bottom of the pressure block 221 through the atomizing nozzle 324, so that the lubricant adheres to the bottom of the pressure block 221, and then when the pressure block 221 squeezes the rubber plastic gasket, the rubber plastic gasket will not stick to the bottom of the pressure block 221, thereby preventing the pressure block 221 from not being able to move when the pressure block 221 rises. The rubber plastic gasket will be driven up, so that the plane detector can better observe the recovery of the rubber plastic gasket, thereby making the compression test result of the rubber plastic gasket more accurate. When it is necessary to prevent the lubricant at the bottom of the pressure block 221 from penetrating into the interior of the rubber plastic gasket, when the slide plate 22 is in the process of descending, the slide plate 22 drives the pressure block 221 to gradually descend, so that the bottom of the pressure block 221 gradually moves toward the surface of the protective film 412. As the pressure block 221 continues to descend, the pressure block 221 drives the film roller 411 to rotate through the protective film 412, so that the protective film 412 wraps the bottom of the pressure block 221, so that when the pressure block 221 squeezes the rubber plastic gasket, the lubricant at the bottom of the pressure block 221 is wrapped by the protective film The protective film 412 wraps around the rubber plastic gasket and does not enter the interior of the rubber plastic gasket. Due to the dual use of the protective film 412 and the lubricant, the pressure block 221 can be separated from the protective film 412 during the rising process. The protective film 412 will not hinder the recovery of the rubber plastic gasket, thereby making the result of the pressure resistance test more accurate. The pressure block 221 squeezes the rubber plastic gasket. After the squeezing is completed, the pressure block 221 is restored to its initial state through the control panel 11, and then the recovery of the squeezed rubber plastic gasket is observed through the plane detector. The plane detector transmits the observed situation to the interior of the control panel 11. When the used protective film 412 needs to be replaced, after the pressure on the rubber plastic gasket is completed,The pressure cylinder 21 drives the slide plate 22 upward through the pressure column 211, so that the slide plate 22 drives the telescopic rod 511 upward through the support block 51. During the upward process, the telescopic rod 511 transmits the air inside the fixed cylinder 52 through the air guide pipe 522 to the inside of the air guide frame 53 through the sealing plate 512. As the air inside the air guide frame 53 continues to increase, the sealing plate 532 drives the bevel plate 533 to move and stretch the spring 531. During the movement, the bevel plate 533 drives the ratchet 54 to rotate. The film-collecting rod 421 drives the film-collecting roller 422 to rotate, thereby causing the film-collecting roller 422 to rewind the used protective film 412. When the slide plate 22 descends again, the one-way valve 521 opens, allowing the spring 531 to return to its original state without being stretched by the sealing plate 532, thereby causing the beveled tooth plate 533 to return to its original state. When the beveled tooth plate 533 returns to its original state, the beveled teeth at the bottom of the beveled tooth plate 533 deform, thereby preventing the beveled tooth plate 533 from driving the ratchet 54 to reverse, and thus preventing the film-collecting roller 422 from driving the protective film 412 to reverse.
