[0017] Beneficial effects of the present invention:

[0018] 1. The present invention can lower the rubber seals on the multiple placement rods below through the setting of the material discharge assembly, and the setting of the multiple placement rods can continuously test the elasticity of batches of rubber seals. Through the conical setting of the upper layer of the placement rod, the rubber seal can be accurately dropped onto the placement rod after being placed on the placement rod. Through the setting of the pulling plate, the rubber seal sleeved on the placement rod can be circumferentially stretched from the inside to the outside, thereby testing the elasticity inside the rubber seal. Through the setting of the clamping plate, the upper and lower edges of the rubber seal can be clamped and fixed. The clamping plate is an existing clamping device, which will not be described in detail here. The rotation of the rotating ring can pull the clamped rubber seal radially outward. At the same time, after the clamping plate clamps the upper and lower ends of the rubber seal, the upper and lower clamping plates are separated from each other, and the rubber seal can be stretched axially, thereby satisfying the requirements of pulling and testing the elasticity of the rubber seal while also satisfying the requirements of radial and circumferential stretching of the rubber seal, thereby testing the elasticity of the rubber seal.

[0019] 2. The present invention can heat the rubber seal sleeved on the outside of the placement rod through the provision of a hot air blower, thereby simulating the temperature of the rubber seal when actually used on the engine, and further more realistically detecting the heat resistance of the rubber seal, and the electric slider is opened to drive the regulating wheel to rotate, and when the regulating wheel rotates, the middle wheel is driven to rotate, and when the middle wheel rotates, multiple arc plates below are driven to rotate, and the arc plates are rotated so that the air holes on the placement rod and the arc plates are staggered, thereby regulating the temperature of the rubber sealing ring when heated.

[0020] 3. The present invention clamps the upper and lower edges of the rubber seal by opening the clamping plates, and then the electric slider is opened to drive the center wheel to rotate. When the center wheel rotates, the tooth plates on both sides are driven to move away from each other. At this time, the two clamping plates connected to the tooth plates move away from each other synchronously, and then the upper and lower parts of the rubber seal are axially stretched. After stretching, the clamping of the rubber seal is cancelled, and its elasticity is detected by observing whether the rubber seal is restored.

[0021] 4. The present invention drives the placement rod to change position when the rotating seat rotates. At this time, the placement rod without the rubber seal is rotated to the bottom of the unloading assembly. When the rotating seat rotates, the extrusion wheel is driven to rotate synchronously by the driving and belt settings. When the extrusion wheel rotates, it intermittently squeezes the moving rod. After the extrusion wheel cancels the squeezing of the moving rod, the lifting plate drives the annular plate to move downward. When the annular plate moves downward and is in place, the placement rod that has rotated is already on the same axis as the lowering cylinder. Then the electric slider is opened to drive the unloading rod to rotate. When the unloading rod rotates, it drives the two unloading plates to rotate synchronously, and finally the rubber seal in the lowering cylinder is lowered onto the placement rod, thereby facilitating the subsequent stretching operation of the rubber seal.

[0022] 5. The present invention opens an electric slider to drive multiple side panels closer to each other until the upper and lower rectangular boxes on the side panels move into the vertical grooves, and then opens the two-way push rod to retract. When the two-way push rod retracts, it pulls the upper and lower rotating frames to rotate closer to each other. The upper and lower rotating frames rotate closer to each other, and the fixing rod drives the card out of the rectangular box. The card moved out is placed in the card slot, thereby fixing the pulling plate. Then the electric slider opens to drive the multiple side panels away from each other, and the multiple pulling plates pull outward on the inner wall of the rubber sealing ring, thereby realizing the radial tensile test of the rubber sealing ring.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0035] The invention discloses an engine rubber seal detection device, which detects the rubber seal, specifically stretches the inside and edge of the engine rubber seal to observe the resetting condition of the seal and detect its elasticity.

[0036] like Figure 1-Figure 8As shown in the figure, it includes a bottom plate 1. In the middle of the upper end face of the bottom plate 1, a rotating seat 10 is rotatably installed through a motor. An annularly arranged rotating seat 10 is fixedly installed on the outer edge of the upper part of the rotating seat 10. In the middle section of the rotating seat 10, a placing rod 2 is rotatably installed through an electric slider. When the seal is being detected, it is sleeved outside the placing rod 2. Vertical grooves 21 are annularly formed on the outer edge of the placing rod 2. On both the upper and lower sides of the vertical grooves 21, there are L-shaped plates 22 fixedly connected to the inner cavity of the placing rod 2. A pulling plate 23 is placed in the vertical grooves 21. Springs are commonly connected between the pulling plate 23 and the upper and lower L-shaped plates 22. On one side of the bottom plate 1, a T-shaped frame 31 is fixedly installed. In the middle of the T-shaped frame 31, a lifting plate 32 is slidably installed. On the upper end of the lifting plate 32, an annular plate 33 is fixedly installed. A rotating wheel is rotatably installed at the lower part of the lifting plate 32. A picking component is arranged at the rear side of the lifting plate 32. On the upper end face of the annular plate 33, a rotating ring 330 is rotatably installed through an electric slider. A through groove is annularly formed in the middle. A feeding component is arranged above the annular plate 33. A vertical plate 332 is slidably installed in the through groove. Moving grooves 333 are symmetrically formed in the upper and lower parts of the middle of the vertical plate 332. A clamping plate 336 arranged in a U-shaped manner is slidably installed in the moving grooves 333.

[0037] A pressure sensor (model: PT124G-116) is arranged outside the placing rod 2. Through the setting of the pressure sensor, the pressure of the rubber seal after tensile testing can be detected. By observing the pressure values of the rubber seal before and after stretching, the elasticity of the seal can be accurately detected.

[0038] Through the setting of the feeding component, rubber seals can be placed on multiple placing rods 2 below. The setting of multiple placing rods 2 can perform continuous elasticity detection on a batch of rubber seals. Through the conical setting of the upper part of the placing rod 2, after the rubber seal is placed on the placing rod 2, it can accurately fall onto the placing rod 2. Through the setting of the pulling plate 23, the rubber seal sleeved on the placing rod 2 can be circumferentially stretched from the inside to the outside, thereby detecting the internal elasticity of the rubber seal. Through the setting of the clamping plate 336, the upper and lower edges of the rubber seal can be clamped and fixed. The clamping plate 336 is an existing clamping device and will not be elaborated here. When the rotating ring 330 rotates, the clamped rubber seal can be radially pulled outward. At the same time, after the upper and lower clamping plates 336 clamp the rubber seal, the upper and lower clamping plates 336 move away from each other, and the rubber seal can be axially stretched, so as to meet the requirement of stretching the rubber seal in both radial and circumferential ways while detecting its elasticity by pulling, and then detecting the elasticity of the rubber seal. After the detected rubber seal rotates to below the picking component along with the placing rod 2, the rubber seal can be taken off the placing rod 2 by the suction cup in the picking component.

[0039] A hot air blower 24 is fixedly installed in the middle of the inner cavity of the placement rod 2, and slots 230 are provided on the upper and lower sides of the pulling plate 23. A middle wheel 25 rotatably connected to the L-shaped plate 22 is provided at the upper part of the inner cavity of the placement rod 2. A through groove is provided on one side of the middle wheel 25, and a regulating wheel 252 is rotatably installed in the through groove through an electric slider. The regulating wheel 252 is meshed with the middle wheel 25, and a circumferentially arranged arc plate 251 is fixedly installed on the lower end surface of the middle wheel 25. The arc plate 251 is located between every two pulling plates 23, and corresponding air holes are provided on the placement rod 2 and the arc plate 251.

[0040] By setting the hot air blower 24, the rubber seal sleeved on the outside of the placement rod 2 can be heated, thereby simulating the temperature of the rubber seal when actually used on the engine, and then more realistically testing the heat resistance of the rubber seal, and the electric slider is opened to drive the regulating wheel 252 to rotate, and when the regulating wheel 252 rotates, it drives the middle wheel 25 to rotate, and when the middle wheel 25 rotates, it drives the multiple arc plates 251 below to rotate, and the arc plates 251 rotate so that the air holes on the placement rod 2 and the arc plates 251 are staggered, thereby regulating the temperature of the rubber sealing ring when it is heated.

[0041] A plurality of circumferentially arranged push-pull plates 331 are rotatably installed on the inner side of the rotating ring 330, and the push-pull plates 331 are hinged to the tops of the corresponding vertical plates 332 at one end away from the rotating ring 330. A center wheel 334 is rotatably installed in the middle part of the side away from the plurality of vertical plates 332 through an electric slider, and tooth plates 335 slidably connected to the vertical plates 332 are meshed on both sides of the center wheel 334, and the tooth plates 335 on both sides are fixedly connected to the upper and lower clamping plates 336 respectively.

[0042] When the rubber seal is subjected to axial stretching test, the upper and lower edges of the rubber seal are clamped by opening the clamping plate 336, and then the electric slider is opened to drive the center wheel 334 to rotate. When the center wheel 334 rotates, it drives the tooth plates 335 on both sides to move away from each other. At this time, the two clamping plates 336 connected to the tooth plates 335 move away from each other synchronously, and then the upper and lower parts of the rubber seal are axially stretched. After stretching, the clamping of the rubber seal is cancelled, and its elasticity is tested by observing whether the rubber seal is restored.

[0043] The unloading assembly includes a support frame 34, which is fixedly mounted on the upper end surface of the annular plate 33. A lowering cylinder 341 is fixedly mounted in the middle of the support frame 34. A fixing ring 342 is fixedly mounted on the outer ring of the lowering cylinder 341. A unloading rod 343 is rotatably mounted on one side of the fixing ring 342 through an electric slider. Two staggered unloading plates 344 are fixedly mounted on the lower part of the unloading rod 343. One side of the two unloading plates 344 is provided with a through groove opened on the lowering cylinder 341. When the two unloading plates 344 rotate, they are staggered in sequence in the through groove.

[0044] The motor is turned on to drive the rotating seat 10 to rotate. When the rotating seat 10 rotates, it drives the placement rod 2 to change position. At this time, the placement rod 2 without the rubber seal is rotated to the bottom of the unloading assembly. When the rotating seat 10 rotates, it drives the extrusion wheel 14 to rotate synchronously through the driving and belt settings. When the extrusion wheel 14 rotates, it intermittently squeezes the moving rod 311. After the extrusion wheel 14 cancels the squeezing of the moving rod 311, the lifting plate 32 drives the annular plate 33 to move downward. When the annular plate 33 moves downward and is in place, the placement rod 2 that has rotated at this time is already on the same axis as the lowering cylinder 341. Then the electric slider is turned on to drive the unloading rod 343 to rotate. When the unloading rod 343 rotates, it simultaneously drives the two unloading plates 344 to rotate, and finally the rubber seal in the lowering cylinder 341 is lowered onto the placement rod 2, thereby facilitating the subsequent stretching operation of the rubber seal.

[0045] The picking assembly includes an outer plate 35 which is arranged in an arc shape and fixedly connected to the lifting plate 32 . A picking tube 36 is fixedly installed on one side of the outer plate 35 away from the lifting plate 32 . A suction cup is circumferentially arranged in the inner cavity of the picking tube 36 .

[0046] When the rubber seal after elasticity detection rotates to the bottom of the picking assembly along with the placement rod 2, the suction cup in the picking tube 36 opens, and the rubber seal on the placement rod 2 is adsorbed and removed, and finally falls into the collection box 11 for storage.

[0047] A hydraulic rod 41 is fixedly installed on one side of the upper end surface of the base plate 1, and a double-ring plate 42 is fixedly installed on the telescopic end of the hydraulic rod 41. A ring-shaped side plate 43 is slidably installed on the lower end surface of the double-ring plate 42 through an electric slider. A symmetrically arranged sliding rod 44 is slidably installed in the middle of the side plate 43, and a rectangular box 45 is fixedly installed on one end of the sliding rod 44. A spring is sleeved on the outside of the sliding rod 44.

[0048] A clamp 451 is installed in the middle of the rectangular box 45 for sliding up and down. Rectangular openings are symmetrically opened on the sides of the upper and lower rectangular boxes 45 that are close to each other. Through slots are opened on the rectangular box 45 on the front and back sides of the clamp 451. A fixing rod 452 that passes through the through slot is fixedly installed in the middle of the clamp 451. A two-way push rod 47 fixedly connected to the side plate 43 is provided between the upper and lower rectangular boxes 45. A rotating frame 46 symmetrically installed up and down is rotatably installed on the side plate 43. The rotating frame 46 is sleeved on the outside of the fixing rod 452, and the telescopic rods of the two-way push rod 47 are fixedly connected to the upper and lower rotating frames 46 respectively.

[0049] When the rubber seal is subjected to radial tensile testing, the electric slider is opened to drive the multiple side plates 43 closer to each other until the upper and lower rectangular boxes 45 on the side plates 43 move into the vertical groove 21, and then the two-way push rod 47 is opened to retract. When the two-way push rod 47 retracts, it pulls the upper and lower rotating frames 46 to rotate closer to each other. The upper and lower rotating frames 46 rotate closer to each other, and at this time, the fixing rod 452 drives the card 451 to move out of the rectangular box 45. At this time, the moved card 451 is placed in the card groove 230, thereby fixing the pulling plate 23, and then the electric slider is opened to drive the multiple side plates 43 away from each other. At this time, the multiple pulling plates 23 are pulled outward on the inner wall of the rubber sealing ring, thereby realizing the radial tensile test of the rubber sealing ring. When the bidirectional push rod 47 is pushed upward, the upper and lower rotating frames 46 rotate away from each other. At this time, the upper and lower rotating frames 46 place the clamp 451 into the rectangular box 45 through the fixing rod 452, thereby canceling the fixation of the pulling plate 23. The pulling plate 23 moves into the vertical groove 21 under the action of the spring, canceling the stretching of the rubber sealing ring. At this time, the rubber sealing ring loses the stretching force. At this time, observing whether the rubber sealing ring is reset can detect its elasticity.

[0050] A collecting box 11 is provided in an annular manner outside the rotating seat 10 . The collecting box 11 is located between two extension plates 12 . The collecting box 11 is detachably connected to the rotating seat 10 .

[0051] A rotating rod 13 rotatably connected to the base plate 1 is provided on one side of the rotating seat 10. Pulleys are fixedly installed on the rotating seat 10 and the rotating rod 13, and a belt is provided between the pulleys. An extrusion wheel 14 is fixedly installed in the middle of the rotating rod 13. An extrusion frame 310 is slidably installed in the inner cavity of the T-frame 31. A moving rod 311 is fixedly installed on one side of the extrusion frame 310. The moving rod 311 penetrates and slides in the T-frame 31. A rotating wheel is rotatably installed on the end of the moving rod 311 away from the extrusion frame 310, and the rotating wheel is always in contact with the extrusion wheel 14.

[0052] When the card 451 is placed in the card slot 230, the electric slider opens and drives the multiple side plates 43 to move away from each other. At this time, the pulling plate 23 follows the movement of the side plate 43, and then can stretch the inner side of the seal outward, so as to detect the elasticity of the inner wall of the seal. After the clamping plate 336 clamps the outer edge of the end of the seal, the multiple vertical plates 332 move away from each other to realize the tensile test of the outer edge of the end of the seal.

[0053] When the present invention is in use, first, the material discharging assembly lowers the rubber seals on the multiple placement rods 2 below. The arrangement of the multiple placement rods 2 can continuously test the elasticity of batches of rubber seals. By setting the conical layer of the placement rod 2, the rubber seals can be accurately dropped onto the placement rod 2 after being placed on the placement rod 2. By setting the pulling plate 23, the rubber seals sleeved on the placement rod 2 can be stretched circumferentially from the inside to the outside, thereby testing the elasticity inside the rubber seals. By setting the clamping plate 336, the upper and lower edges of the rubber seals can be clamped and fixed. The clamping plate 336 is an existing clamping plate. The device will not be described in detail here. The rotation of the rotating ring 330 can pull the clamped rubber seal radially outward. At the same time, after the clamping plates 336 clamp the upper and lower ends of the rubber seal, the upper and lower clamping plates 336 are separated from each other, and the rubber seal can be stretched axially, thereby satisfying the requirements of pulling and testing the elasticity of the rubber seal, and also satisfying the requirements of radial and circumferential stretching of the rubber seal, thereby testing the elasticity of the rubber seal. After the rubber seal is tested, it rotates to the bottom of the pick-up assembly along with the placement rod 2, and the rubber seal can be removed from the placement rod 2 by the suction cup in the pick-up assembly.

[0054] The setting of the hot air blower 24 can heat the rubber seal sleeved on the outside of the placement rod 2, thereby simulating the temperature of the rubber seal when it is actually used on the engine, and then more realistically testing the heat resistance of the rubber seal, and the electric slider is opened to drive the regulating wheel 252 to rotate, and when the regulating wheel 252 rotates, it drives the middle wheel 25 to rotate, and when the middle wheel 25 rotates, it drives the multiple arc plates 251 below to rotate, and the arc plates 251 rotate so that the air holes on the placement rod 2 and the arc plates 251 are staggered, thereby heating the rubber seal ring. The temperature of the rubber seal is regulated when it is hot. When the rubber seal is subjected to axial stretching test, the upper and lower edges of the rubber seal are clamped by opening the clamping plate 336. Then the electric slider is opened to drive the center wheel 334 to rotate. When the center wheel 334 rotates, the tooth plates 335 on both sides are driven to move away from each other. At this time, the clamping plates 336 connected to the tooth plates 335 are synchronously moved away from each other, thereby axially stretching the upper and lower parts of the rubber seal. After stretching, the clamping of the rubber seal is cancelled, and its elasticity is tested by observing whether the rubber seal is restored.

[0055] When the motor is turned on, it drives the rotating seat 10 to rotate. When the rotating seat 10 rotates, it drives the placement rod 2 to change position. At this time, the placement rod 2 without the rubber seal placed thereon rotates to the bottom of the blanking assembly. When the rotating seat 10 rotates, it drives the extrusion wheel 14 to rotate synchronously through the drive and belt settings. When the extrusion wheel 14 rotates, it intermittently squeezes the moving rod 311. After the extrusion wheel 14 cancels the squeezing of the moving rod 311, the lifting plate 32 drives the annular plate 33 to move downward. When the annular plate 33 moves downward into position, the placement rod 2 that has rotated at this time has the same axis as the lowering cylinder 341. Then the electric slider is turned on to drive the blanking rod 343 to rotate. When the blanking rod 343 rotates, it drives the two blanking plates 344 to rotate synchronously, and finally the rubber seal in the lowering cylinder 341 is lowered onto the placement rod 2, thereby facilitating the subsequent stretching operation of the rubber seal.

[0056] When the rubber seal is subjected to radial tensile testing, the electric slider is opened to drive the multiple side plates 43 closer to each other until the upper and lower rectangular boxes 45 on the side plates 43 move into the vertical groove 21, and then the two-way push rod 47 is opened to retract. When the two-way push rod 47 retracts, it pulls the upper and lower rotating frames 46 to rotate closer to each other. The upper and lower rotating frames 46 rotate closer to each other, and at this time, the fixing rod 452 drives the card 451 to move out of the rectangular box 45. At this time, the moved card 451 is placed in the card groove 230, thereby fixing the pulling plate 23, and then the electric slider is opened to drive the multiple side plates 43 away from each other. At this time, the multiple pulling plates 23 are pulled outward on the inner wall of the rubber sealing ring, thereby realizing the radial tensile test of the rubber sealing ring. When the bidirectional push rod 47 is pushed upward, the upper and lower rotating frames 46 rotate away from each other. At this time, the upper and lower rotating frames 46 place the clamp 451 into the rectangular box 45 through the fixing rod 452, thereby canceling the fixing of the pulling plate 23. The pulling plate 23 moves into the vertical groove 21 under the action of the spring, canceling the stretching of the rubber sealing ring. At this time, the rubber sealing ring loses its stretching force. At this time, observing whether the rubber sealing ring is reset can detect its elasticity;

[0057] After the elasticity test, the rubber seal rotates to the bottom of the picking assembly along with the placement rod 2, and the suction cup in the picking tube 36 opens to absorb and remove the rubber seal on the placement rod 2, and finally drops it into the collection box 11 for storage.

[0058] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
