Description

Technical Field

[0001] This utility model relates to the technical field of detecting the elasticity of rubber sealing rings, and in particular to a rubber sealing ring elasticity testing device. Background Technology

[0002] A workshop produces rubber sealing ring 1 with the following structure: Figures 1-2 As shown, the rubber sealing ring 1 is circular in shape, and a central hole 2 coaxial with it is opened in the middle of the rubber sealing ring 1. This rubber sealing ring 1 is mainly used to be installed in the joint of a valve to play a sealing role.

[0003] After a batch of rubber sealing rings 1 is produced in the workshop, the process involves using a tensile testing machine to test the elasticity of each rubber sealing ring 1. After testing, workers place rubber sealing rings 1 with the required elasticity into the finished product basket, and those with the required elasticity into the waste basket. The method used by workers to test the elasticity of the rubber sealing rings 1 using a tensile testing machine is as follows:

[0004] S1. The worker takes out a rubber sealing ring 1 to be tested from the material basket;

[0005] S2. Place the lower end of the rubber sealing ring 1 into the lower clamp of the tensile testing machine, and tighten the locking screw 3 of the lower clamp. At this time, the two clamps 4 of the lower clamp will fix the lower end of the rubber sealing ring 1 in place. Figure 3 As shown, this achieves the fixation of the rubber sealing ring 1;

[0006] S3. The upper end of the rubber sealing ring 1 is clamped by the upper clamp of the tensile testing machine. Then, the piston rod of the cylinder of the tensile testing machine is controlled to retract upward. The piston rod drives the upper clamp to move upward, and the upper clamp pulls the rubber sealing ring 1 upward. The direction of pulling the rubber sealing ring 1 is as follows: Figure 3 As shown by the middle arrow; when the rubber sealing ring 1 is stretched to the set length, the display screen of the tensile testing machine shows the elasticity of the rubber sealing ring 1;

[0007] If the elasticity is within the specified range, the worker determines that the tested rubber seal 1 is a qualified product; if the elasticity is not within the specified range, the worker determines that the tested rubber seal 1 is a defective product, thus ultimately achieving the testing of the elasticity of the first rubber seal 1.

[0008] S4. The worker opens the upper and lower clamps, and then removes the qualified or unqualified products. The qualified products are placed in the finished product basket, or the unqualified products are placed in the waste basket.

[0009] S5. Workers can repeat steps S1 to S4 multiple times to test the elasticity of all rubber sealing rings 1 in the workshop.

[0010] However, although the tensile testing machine used in the workshop can test the elasticity of the rubber seal 1, the following technical defects still exist in actual operation:

[0011] I. In step S2, the worker needs to tighten the locking screw 3 of the lower clamp of the tensile testing machine in order to fix the rubber sealing ring 1 through the lower clamp. The worker needs to tighten the locking screw 3 multiple times in order to fix the rubber sealing ring 1 through the lower clamp, and then the rubber sealing ring 1 can enter the testing station. This undoubtedly increases the testing time of the elasticity of the rubber sealing ring 1, and thus reduces the efficiency of testing the elasticity of the rubber sealing ring 1.

[0012] II. Only one rubber sealing ring 1 can be tested for elasticity at a time, which takes a long time to test all the rubber sealing rings 1 in the basket, thus further reducing the efficiency of testing the elasticity of the rubber sealing rings 1.

[0013] Therefore, there is an urgent need for a testing device that can greatly improve the efficiency of detecting the elasticity of rubber seals. Utility Model Content

[0014] The purpose of this invention is to overcome the shortcomings of the prior art and provide a rubber sealing ring elasticity testing device that greatly improves the efficiency of testing rubber sealing ring elasticity.

[0015] The purpose of this utility model is achieved through the following technical solution: a rubber sealing ring elasticity testing device, which includes a gantry frame fixed on the top surface of the workbench, a vertical plate fixed on the bottom surface of the gantry frame beam, two fixed columns fixed on the left and right end faces of the vertical plate and along its height direction, a cylinder fixed on the outer end face of the fixed column, and a stepped surface formed between the cylinder and the fixed column.

[0016] A lifting cylinder is fixedly mounted on the bottom surface of the workbench. The piston rod of the lifting cylinder extends upward through the workbench, and a lifting plate is fixedly mounted on the extended end. The lifting plate is located directly below the vertical plate. A horizontally arranged double-acting cylinder is fixedly mounted on the top surface of the lifting plate. An upwardly extending connecting plate is fixedly mounted on each of the two piston rods of the double-acting cylinder. The two connecting plates are located on the left and right sides of the vertical plate, respectively. Two elastic force detectors are fixedly mounted on the inner end face of each connecting plate. The two elastic force detectors are respectively opposed to the two cylinders on the left and right, and the bends of the elastic force detectors face downward.

[0017] Multiple support legs, which are fixed to the ground, are fixed on the bottom surface of the workbench.

[0018] The diameter of the fixed column is larger than the diameter of the cylinder, and the fixed column is coaxial with the cylinder.

[0019] A flange seat is fixed to the top of the vertical plate, and the flange seat is fixed to the crossbeam of the gantry frame by screws.

[0020] The elasticity detection device also includes a controller, which is electrically connected to the lifting cylinder and the double-acting cylinder via signal lines.

[0038] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description:

[0039] like Figures 4-9 As shown, a rubber sealing ring elasticity testing device includes a gantry frame 6 fixed to the top surface of a workbench 5. A vertical plate 7 is fixed to the bottom surface of the crossbeam of the gantry frame 6. Two fixed columns 8 are fixed to the left and right end faces of the vertical plate 7 along its height direction. A cylinder 9 is fixed to the outer end face of the fixed column 8. The diameter of the fixed column 8 is larger than the diameter of the cylinder 9, and the fixed column 8 and the cylinder 9 are coaxial. A stepped surface 10 is formed between the cylinder 9 and the fixed column 8. Multiple support legs supporting the ground are fixed to the bottom surface of the workbench 5.

[0040] A lifting cylinder 11 is fixedly mounted on the bottom surface of the workbench 5. The piston rod of the lifting cylinder 11 extends upward through the workbench 5, and a lifting plate 12 is fixedly mounted on the extended end. The lifting plate 12 is located directly below the vertical plate 7. A horizontally arranged double-acting cylinder 13 is fixedly mounted on the top surface of the lifting plate 12. An upwardly extending connecting plate 14 is fixedly mounted on each of the two piston rods of the double-acting cylinder 13. The two connecting plates 14 are located on the left and right sides of the vertical plate 7, respectively. Two elastic force detectors 15 are fixedly mounted on the inner end face of each connecting plate 14. The two elastic force detectors 15 are respectively opposed to the two cylinders 9 on the left and right sides, and the bends 16 of the elastic force detectors 15 face downward.

[0041] A flange seat 17 is fixed to the top of the upright plate 7, and the flange seat 17 is fixed to the crossbeam of the gantry frame 6 by screws. The elasticity detection device also includes a controller, which is electrically connected to the lifting cylinder 11 and the double-acting cylinder 13 via signal lines. The worker can control the piston rod of the lifting cylinder 11 to extend or retract upwards through the controller. At the same time, the worker can also control the two piston rods of the double-acting cylinder 13 to extend outwards or retract inwards, thereby facilitating the worker's operation.

[0042] The method by which workers use this testing device to test the elasticity of rubber seal 1 is as follows:

[0043] S1. The four rubber sealing rings 1 are brought into the testing station. The specific operating steps are as follows:

[0044] S11, The worker took out four such... Figures 1-2The rubber sealing rings 1 to be tested are shown. Two of the rubber sealing rings 1 are fitted onto the two cylinders 9 on the left side, and the rubber sealing rings 1 are placed against the stepped surface between the cylinder 9 and the fixed column 8, so that the two rubber sealing rings 1 enter the testing station. Figure 10 As shown, at this time, the center holes 2 of the two rubber sealing rings 1 on the left are respectively opposite to the elbows 16 of the two elasticity testers 15 on the left;

[0045] S12. The worker puts the other two rubber sealing rings 1 on the two cylinders 9 on the right side and puts the rubber sealing rings 1 against the step surface between the cylinder 9 and the fixed column 8, so that the two rubber sealing rings 1 enter the testing station. At this time, the center hole 2 of the two rubber sealing rings 1 on the right side is opposite to the elbow 16 of the two elasticity testers 15 on the right side.

[0046] As can be seen from step S1, the worker only needs to put the rubber sealing ring 1 on the cylinder 9 and place the rubber sealing ring 1 against the step surface between the cylinder 9 and the fixed column 8 to allow the rubber sealing ring 1 to quickly enter the testing station. Compared with the testing method using a tensile testing machine in the workshop, the worker does not need to tighten the locking screw 3 of the lower clamp of the tensile testing machine to fix the rubber sealing ring 1 before it can enter the testing station. This undoubtedly shortens the testing time of the elasticity of the rubber sealing ring 1 and thus greatly improves the efficiency of testing the elasticity of the rubber sealing ring 1.

[0047] S2. The two piston rods of the double-acting cylinder 13 retract, causing the connecting plate 14 connected to it to move towards the vertical plate 7. The connecting plate 14 then causes the elastic force detector 15 connected to it to move synchronously. When the two piston rods of the double-acting cylinder 13 are fully retracted, the bends 16 of the two elastic force detectors 15 on the left side respectively enter the center holes 2 of the two rubber sealing rings 1 on the left side. Figure 11 As shown, at the same time, the elbows 16 of the two elasticity testers 15 on the right side are respectively inserted into the center holes 2 of the two rubber sealing rings 1 on the right side;

[0048] S3. The piston rod of the lifting cylinder 11 retracts downward, causing the lifting plate 12 to move downward. The lifting plate 12 then causes the double-acting cylinder 13 and the two connecting plates 14 to move downward. The connecting plates 14 cause the elasticity detector 15 fixed on them to move downward. The elasticity detector 15 causes the elbow 16 on it to move downward synchronously. The elbow 16 pulls the lower end of the rubber sealing ring 1 downward in the following direction: Figure 12 As shown by the middle arrow; when the piston rod of the lifting cylinder 11 retracts to the set distance, the controller controls the lifting cylinder 11 to close. At this time, the four rubber sealing rings 1 are just in a stretched state, and the elasticity value of the corresponding rubber sealing ring 1 is displayed on the elasticity detector 15.

[0049] If the elasticity value is within the specified range, the worker determines that the tested rubber seal 1 is a qualified product; if the elasticity value is not within the specified range, the worker determines that the tested rubber seal 1 is a defective product, thus completing the elasticity test of four rubber seals 1 in one go.

[0050] S4. After the inspection is completed, the worker controls the piston rod of the lifting cylinder 11 to extend upward, and then controls the two piston rods of the double-acting cylinder 13 to extend outward. The piston rods drive the connecting plate 14 to move away from the vertical plate 7, and the connecting plate 14 drives the elasticity detector 15 to move outward synchronously. When the two piston rods of the double-acting cylinder 13 are fully extended, each elasticity detector 15 is reset. The worker removes the defective and qualified products from the cylinder 9, and puts the defective products into the waste basket or the qualified products into the finished product basket.

[0051] S5. Workers can repeat steps S1 to S4 multiple times to test the elasticity of all rubber sealing rings 1 in the workshop.

[0052] As can be seen from steps S1 to S5, the worker only needs to first put the four rubber sealing rings 1 to be tested onto the four cylinders 9 respectively, and then through the linkage of the lifting cylinder 11 and the double-acting cylinder 13, the elasticity of all four rubber sealing rings 1 can be tested at once. Compared with the tensile testing machine in the workshop, which can only test one rubber sealing ring 1 at a time, this method enables all rubber sealing rings 1 in the basket to be tested in a short time, thereby greatly improving the efficiency of testing rubber sealing rings 1.

[0053] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
