Description

Technical Field

[0001] The utility model relates to the technical field of fatigue detection, in particular to an elastic body detection device. Background Art

[0002] Elastomers refer to parts or materials with high elasticity. They can deform under the action of force and return to their original shape when the force is removed. They mainly include springs, rubber and metal shrapnel, among which rubber parts include rubber rollers. Wear life is one of the main performance indicators of elastomers represented by rubber. After the production and manufacturing of elastomers, it is generally necessary to carry out random inspections of wear life. In order to facilitate the rapid, convenient and effective inspection of elastomers, it is necessary to specially design a device suitable for elastomer fatigue detection.

[0003] In order to facilitate the increase or decrease of the counterweight that applies downward force, some existing detection devices use a water tank filled with water as a counterweight mechanism. However, the counterweight water tank often lacks a mechanism that can suppress the shaking of the water inside. As a result, when the water tank is not fully loaded, the water inside will experience violent inertial (up and down) shaking following the detection movement, causing the downward pressure load applied to the elastic body to fluctuate greatly, making it difficult to maintain balance, thereby affecting the stability and accuracy of the detection operation. Utility Model Content

[0004] In view of this, the utility model provides an elastomeric detection device to solve the problem that most counterweight water tanks lack a mechanism that can suppress the shaking of the water inside, resulting in the counterweight water shaking violently (up and down) due to inertia following the detection movement when the water tank is not fully loaded, affecting the stability and accuracy of the detection operation.

[0005] The technical solution proposed by the utility model is: an elastic body detection device, specifically comprising a base, a holding frame and a counterweight water tank; a holding frame is slidably installed on the top of the base, and a counterweight water tank is supported and installed on the top of the holding frame;

[0006] A baffle is slidably installed inside the counterweight water tank, and a rubber sealing ring is inlaid on the periphery of the baffle, and the baffle is used to block and limit the ups and downs and shaking of the water inside the counterweight water tank; a positioning frame is welded to the middle position of the top of the counterweight water tank, and a threaded push rod is screwed through the middle position of the positioning frame, and the bottom of the threaded push rod is rotatably connected to the baffle; a water valve is installed at the bottom position of the rear side wall of the counterweight water tank, and a water valve is also installed on the top of the baffle, the water valve on the upper side is used for water intake, and the water valve on the bottom side is used for water discharge.

[0007] Furthermore, two rectangular sliding frames are symmetrically welded on the retaining frame, and a horizontally arranged bearing plate is welded on the top of the retaining frame, and the counterweight water tank is detachably fixedly connected to the bearing plate.

[0008] Furthermore, a track frame with a U-shaped structure is welded symmetrically on the top of the base, and two rectangular sliding frames are slidably matched with the top longitudinal support parts of the two track frames.

[0009] Furthermore, two vertical mounting plates are slidably mounted on the bottom side of the retaining frame in a left-right symmetrical manner, and the rubber roller to be detected is rotatably mounted between the bottom side parts of the two vertical mounting plates.

[0010] Furthermore, a vertical threaded shaft is rotatably mounted in the middle of the bottom side of the retaining frame, a threaded ring is screwed onto the vertical threaded shaft, and two inclined pull rods are rotatably connected between the threaded ring and two vertical mounting plates.

[0011] Furthermore, two mounting plates are welded symmetrically on the bottom sides of the two vertical mounting plates, and two blocks arranged opposite to each other are installed on the bottom sides of the two mounting plates by screw locking. A ball is embedded and installed at the head end of the two blocks, and the two balls are in contact with the two ends of the rubber roller shaft.

[0012] Furthermore, mounting rings are welded above the top ends of the rear sides of the two track frames, in which a detection motor is installed by screw locking, a rotating wheel is mounted on the top end of the rotating shaft of the detection motor, a connecting rod is rotatably connected to the circumferential outer ring of the rotating wheel, and the tail end of the connecting rod is rotatably connected to the retaining frame.

[0013] The utility model provides an elastic body detection device, which has the following beneficial effects:

[0014] When the utility model is in use, when adjusting the load, it is only necessary to increase or decrease the water volume inside the counterweight water tank through two water valves. Compared with the existing technology that uses a solid counterweight block as the load-bearing load, the trouble of actually lifting and disassembling the solid counterweight block when adjusting the load can be eliminated, and the operation and use are convenient.

[0015] In addition, the baffle is used to block and limit the ups and downs and shaking of the water inside the counterweight water tank. Compared with the existing technology, it can prevent the water inside the tank from shaking violently due to inertia (up and down) following the detection movement when the water tank is not fully loaded. The impact changes the bearing load applied to the elastomer, so that the bearing load remains balanced, which is beneficial to ensure the stability and accuracy of the detection operation.

[0016] In addition, the two blocks are used to limit the rubber roller to a position between the two vertical mounting plates, and the two blocks are in indirect contact with the rubber roller shaft through the two rolling balls, which can reduce the mutual wear between the two blocks and the rubber roller shaft.

[0033] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the described embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Example 1, please refer to Figures 1 to 6 :

[0035] The present embodiment proposes an elastic body detection device, including a base 1, a holding frame 3 and a counterweight water tank 4; a holding frame 3 is slidably installed on the top of the base 1, and a counterweight water tank 4 is supported and installed on the top of the holding frame 3. The counterweight water tank 4 applies a downward bearing load to the rubber roller 6 during the detection process through the gravity generated by the water in the counterweight water tank 4, simulating the load-bearing of the rubber roller 6 in the actual use state. When adjusting the load, it is only necessary to increase or decrease the amount of water in the counterweight water tank 4 through two water valves 404. Compared with the existing technology that uses a physical counterweight block as the load-bearing load, the trouble of lifting and disassembling the physical counterweight block when adjusting the load can be eliminated, and the operation and use are convenient;

[0036] Among them, a baffle 402 is slidably installed inside the counterweight water tank 4, and a rubber sealing ring is embedded and installed on the periphery of the baffle 402. The baffle 402 is used to block and limit the ups and downs of the water inside the counterweight water tank 4. Compared with the existing technology, it can prevent the water inside the water tank from being violently inertially (up and down) shaking with the detection movement when it is not fully loaded, and the impact changes the load applied to the elastic body, so that the load is balanced, which is conducive to ensuring the stability and accuracy of the detection operation; a positioning frame 4 is welded at the middle position of the top of the counterweight water tank 4 01, a threaded propulsion rod 403 is screwed through the middle position of the positioning frame 401, and the bottom of the threaded propulsion rod 403 is rotatably connected to the baffle 402; a water valve 404 is installed at the bottom position of the rear side wall of the counterweight water tank 4, and a water valve 404 is also installed on the top of the baffle 402. The upper water valve 404 is used for water intake, and the bottom water valve 404 is used for water discharge. The threaded propulsion rod 403 is used for forward and reverse rotation to drive the baffle 402 to slide up and down inside the counterweight water tank 4, which is suitable for the rise and fall of the water level inside the counterweight water tank 4.

[0037] Specifically,

[0038] The retaining frame 3 is a rectangular structure, and two rectangular sliding frames 302 are symmetrically welded on the left and right vertical support rods. A horizontally arranged bearing plate 301 is welded on the top of the retaining frame 3, and the counterweight water tank 4 is detachably fixedly connected to the bearing plate 301.

[0039] Specifically,

[0040] The top of the base 1 is symmetrically welded with a track frame 101 of a U-shaped structure, and two rectangular sliding frames 302 are correspondingly slidably matched with the top longitudinal support parts of the two track frames 101.

[0041] Specifically,

[0042] Two vertical mounting plates 5 are slidably mounted on the bottom side of the retaining frame 3 in a bilaterally symmetrical manner, and a rubber roller 6 to be detected is rotatably mounted between the bottom sides of the two vertical mounting plates 5 .

[0043] Specifically,

[0044] A vertical threaded shaft 303 is rotatably installed in the middle position of the bottom side of the retaining frame 3, and a threaded ring 304 is screwed onto the vertical threaded shaft 303. Two inclined pull rods are rotatably connected between the threaded ring 304 and the two vertical mounting plates 5. The two pull rods, the two vertical mounting plates 5 and the threaded ring 304 are connected together to form two crank slider mechanisms. Through these two mechanisms, the threaded ring 304 that slides up and down can push and drive the two vertical mounting plates 5 to slide left and right toward each other, and be combined and pulled together with the rotating shaft sleeve of the rubber roller 6 to be disassembled and assembled, and the vertical threaded shaft 303 is used for forward and reverse rotation to drive the threaded ring 304 to slide up and down, thereby providing driving force for disassembly and assembly of the rubber roller 6.

[0045] Specifically,

[0046] Two mounting plates 501 are welded symmetrically on the bottom sides of the two vertical mounting plates 5. Two blocks 502 arranged opposite to each other are installed on the bottom sides of the two mounting plates 501 by screw locking. A ball is inlaid and installed at the head end of each block 502. The two balls are in contact with the two ends of the rotating shaft of the rubber roller 6. The two blocks 502 are used to block and limit the rubber roller 6 between the two vertical mounting plates 5, and the two blocks 502 are in indirect contact with the rotating shaft of the rubber roller 6 through the two balls. The two balls can reduce the mutual wear between the two blocks 502 and the rotating shaft of the rubber roller 6.

[0047] Based on the first embodiment, the second embodiment:

[0048] A mounting ring 102 is welded on the top of the rear side of the two track frames 101, and a detection motor 2 is installed in the mounting ring 102 by screw locking. A rotating wheel 201 is mounted on the top of the rotating shaft of the detection motor 2. A connecting rod 202 is rotatably connected to the circumferential outer ring of the rotating wheel 201, and the tail end of the connecting rod 202 is rotatably connected to the retaining frame 3. The rotating wheel 201, the connecting rod 202 and the retaining frame 3 are connected together to form a crank slider mechanism. Through this mechanism, the detection motor 2 can be rotated to push and drive the retaining frame 3 and the rubber roller 6 to slide back and forth along the two track frames 101, so as to implement rolling wear resistance detection on the rubber roller 6.

[0049] Working principle: The weighted water tank 4 applies a downward bearing load to the rubber roller 6 during the detection process through the gravity generated by the water inside it, simulating the load-bearing of the rubber roller 6 under real use. When adjusting the load-bearing, it is only necessary to increase or decrease the amount of water inside the weighted water tank 4 through two water valves 404. The baffle 402 is used to block and limit the ups and downs of the water inside the weighted water tank 4, to prevent the water inside the water tank from shaking violently (up and down) due to inertia when the water tank is not fully loaded following the detection movement, and to change the load applied to the elastic body by impact, so that the load-bearing load is kept balanced. The threaded propulsion rod 403 is used for forward and reverse rotation propulsion to drive the baffle 402 to slide up and down inside the weighted water tank 4, which is suitable for the rise and fall of the water level inside the weighted water tank 4.

[0050] The rubber roller 6 to be tested is rotatably installed between the bottom parts of the two vertical mounting plates 5. The two pull rods, the two vertical mounting plates 5 and the threaded ring 304 are connected together to form two crank slider mechanisms. Through these two mechanisms, the threaded ring 304 that slides up and down can push and drive the two vertical mounting plates 5 to slide left and right toward each other, and the rotating shaft sleeve of the rubber roller 6 is inserted and separated by pulling and pulling to disassemble and assemble the rubber roller 6. The vertical threaded shaft 303 is used to rotate forward and reverse to drive the threaded ring 304 to slide up and down, providing a disassembly and assembly driving force for the rubber roller 6. The two stoppers 502 are used to block and limit the rubber roller 6 between the two vertical mounting plates 5.

[0051] The rotating wheel 201, the connecting rod 202 and the holding frame 3 are connected together to form a crank slider mechanism, through which the detection motor 2 can rotate and push to drive the holding frame 3 and the rubber roller 6 to slide back and forth along the two track frames 101, and perform rolling wear resistance detection on the rubber roller 6;

[0052] After the detection operation begins, the time for which the rubber roller 6 is pushed and continuously rolled is recorded. When the standard test time length is reached, the wear and tear of the rubber roller 6 is checked. If the wear and tear is within the standard value, it means that the wear resistance life is qualified, otherwise it is unqualified.
