DETAILED DESCRIPTION

[0032] 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.

[0033] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the present invention is a rubber sealing ring anti-deformation detection test device, comprising a base 1, a supporting side plate 2 is arranged on one side of the upper end of the base 1, and further comprising:

[0034] The feeding mechanism 3 is arranged on the supporting side plate 2 and is used to take out the rubber sealing rings stored inside one by one.

[0035] The test truncated table 4 is fixedly arranged on the base 1 , a stepped groove 41 is arranged on the upper end of the test truncated table 4 , a limiting annular groove 42 is arranged on the inner wall of the test truncated table 4 , and the test truncated table 4 is located directly below the feeding mechanism 3 .

[0036] The rotating cross 5 is rotatably matched with the step groove 41. A pair of first slide grooves 51 and second slide grooves 52 are respectively provided on the upper end of the rotating cross 5 in the horizontal and vertical directions. A limiting pulley 54 is rotatably installed at the bottom of the rotating cross 5. The limiting pulley 54 is adapted to be slidably installed in the limiting slide groove. The rotating cross 5 is provided with levers 55 at both ends and locking parts 56 at the other two ends. A push-pull cylinder 6 is fixedly provided at the center of the rotating cross 5.

[0037] Specifically, the rotating cross 5 can rotate freely in the stepped groove 41, so that the tensile test angle for the rubber sealing ring can be adjusted. During the rotation process, the limiting pulley 54 will always keep sliding in the limiting slide groove to improve the rotation stability of the rotating cross 5. At the same time, after the test angle is adjusted, the locking parts 56 at both ends are used to lock and position the rotating cross 5 so that it will not rotate or shake during the test.

[0038] The test slider 7, the bottom of the test slider 7 is symmetrically slidably installed on the first slide groove 51 through the first slide seat 71, the upper end of the test slider 7 is provided with a first limit groove 72, and the top end of the output shaft of the push-pull cylinder 6 is rotatably installed with a rotating sleeve 61, the two sides of the rotating sleeve 61 are rotatably matched with one end of the connecting rod 62, and the other end of the connecting rod 62 is rotatably matched with the test slider 7.

[0039] The follower slider 8, the bottom of the follower slider 8 is symmetrically slidably installed on the second slide groove 52 through the second slide seat 81, and a second limiting groove 82 is provided at the upper end of the follower slider 8. The rubber sealing ring to be tested is accommodated in the first limiting groove 72 and the second limiting groove 82.

[0040] Among them, distance measuring sensors 53 are fixedly arranged on both sides of the upper end of the rotating cross 5. The distance measuring sensor 53 is located at one end of the second sliding groove 52 and faces the follow-up sliding block 8.

[0041] It should be noted that the first limiting groove 72 and the second limiting groove 82 in this embodiment have a certain depth, and multiple rubber sealing rings can be stacked and placed at the same time, so that the deformation resistance of a single or multiple sealing rings can be tensile tested separately.

[0042] Specifically, by setting the rotating cross 5, the test slider 7 and the follower slider 8, in the initial state, the rubber sealing ring to be tested is inserted into the first limit groove 72 and the second limit groove 82, and the push-pull cylinder 6 can drive the rotating sleeve 61 to move downward, and drive the test slider 7 to slide toward each other along the first slide groove 51 through the connecting rod 62, so as to start the tensile deformation test of the rubber sealing ring from both ends. In this process, the rubber sealing ring that begins to deform will drive the follower slider 8 to slide synchronously, and the distance sensor 53 is used to monitor the displacement distance change of the follower slider 8 during the deformation process in real time, so as to feedback and analyze the tensile strength of the rubber sealing ring. When it is necessary to adjust the tensile test angle, the rotating cross 5 can be rotated by the lever 55 until it is rotated to the preset tensile angle, so as to realize the tensile test process of the rubber sealing ring at different angles.

[0043] like Figure 3 As shown, a turntable 43 is rotatably installed in the center of the test truncated table 4, and annular marking scale lines 44 are arranged at equal intervals around the turntable 43 at the bottom of the test truncated table 4. Radial sliding grooves 45 are evenly arranged circumferentially at the bottom of the test truncated table 4, and sliding blocks 46 are slidably installed in the sliding grooves 45.

[0044] like Figure 4 As shown, a central axis 431 is fixedly provided at the center of the upper end of the turntable 43, a matching gear 432 is sleeved on the outer side of the central axis 431, a rotating seat 433 is provided at the top of the central axis 431, the rotating seat 433 is rotatably matched with the bottom of the rotating cross 5, and an inclined slide groove 434 is evenly penetrated circumferentially on the turntable 43, an arc-shaped pointer 461 is provided at the top of the sliding block 46, an extension plate 462 is provided at one end of the sliding block 46, a sliding pin 463 is fixedly provided at the bottom of the extension plate 462, and the sliding pin 463 is adapted to be slidably installed in the corresponding inclined slide groove 434.

[0045] like Figure 7 As shown, spur racks 83 are extended from the bottom of the two follower sliders 8, and the two spur racks 83 are centrally symmetrical about the axis of the central axis 431, and the two sides of the matching gear 432 are meshed with the spur racks 83 at the same time.

[0046] Specifically, by setting the turntable 43, when the follow-up slider 8 slides accordingly with the deformation process of the rubber sealing ring, the follow-up slider 8 will synchronously drive the spur rack 83 to perform linear displacement. The spur rack 83 will drive the matching gear 432 to rotate during the displacement process. The matching gear 432 will drive the turntable 43 to rotate through the central axis 431. When the turntable 43 rotates, it will utilize the sliding cooperation between the inclined slide groove 434 and the sliding pin 463 to drive the sliding block 46 to synchronously slide radially along the sliding groove 45, so that the arc pointer 461 indicates on the marked scale lines 44 of different diameters. The tester can intuitively and vividly obtain the tightness of the rubber sealing ring when it expands in annular direction through the reading of the marked scale lines 44, so that the transmission cooperation between the follow-up slider 8, the turntable 43 and the sliding block 46 can be used to realize two different test simulation processes of linear stretching and annular expansion of the rubber sealing ring.

[0047] like Figure 5 As shown, the locking portion 56 includes a fixed slide rod 451, and the end of the rotating cross 5 is connected to the fixed block 562 through the fixed slide rod 451. A locking clamp 564 is slidably provided on the fixed slide rod 451, and a return spring 563 is provided between one side of the locking clamp 564 and the fixed block 562.

[0048] Specifically, by providing the locking portion 56, when the angle of the rotating cross 5 needs to be adjusted, the locking clamps 564 at both ends are pressed and slid outward, at which time the reset spring 563 is squeezed and deformed, and then the rotating cross 5 is rotated by the lever 55. When the angle adjustment is completed, the locking clamps 564 are released, and at this time the locking clamps 564 will be re-clamped on both sides of the test table 4 under the action of the spring, thereby achieving the locking positioning of the rotating cross 5.

[0049] like Figure 6 As shown, a baffle 73 is provided at the top of one side of the first limiting groove 72, and both ends of the baffle 73 are rotatably connected to the test slider 7 through a torsion spring 74. A yielding groove 75 is provided on the other side of the first limiting groove 72, and the baffle 73 is limited and blocked by the yielding groove 75 and is in a horizontal closed state.

[0050] Specifically, by setting the baffle plate 73, during the loading process of the rubber sealing ring, the rubber sealing ring will push the baffle plate 73 to rotate along the yield groove 75 and cause the torsion spring 74 to deform. When the rubber sealing ring enters the first limiting groove 72 and disengages from the baffle plate 73, the baffle plate 73 will rotate in the opposite direction to the yield groove 75 under the action of the torsion spring 74 and remain horizontal, thereby closing the opening at the upper end of the first limiting groove 72 and limiting the position of the rubber sealing ring to prevent the rubber sealing ring from slipping or even breaking and bouncing up to injure people during the tensile test.

[0051] like Figure 8As shown, the feeding mechanism 3 includes a mounting bracket 31 and a feeding cylinder 32. The feeding cylinder 32 is fixedly arranged on the supporting side plate 2. The output end of the feeding cylinder 32 is fixedly connected to one side of the mounting bracket 31. The mounting bracket 31 is provided with a receiving groove 311 for stacking rubber sealing rings. A shell 312 is provided at the four corners of the bottom of the mounting bracket 31. A feeding dial 33 is rotatably installed inside the shell 312. The feeding dial 33 extends into the receiving groove 311. A motor 34 is fixedly arranged on the outside of the shell 312. The output end of the motor 34 is connected to the feeding dial 33.

[0052] Specifically, by setting the feeding mechanism 3, in a stationary state, the feeding plate 33 extends horizontally into the accommodating groove 311, playing a blocking and limiting role to prevent the rubber sealing ring from falling from the bottom; when the rubber sealing ring needs to be replaced, the feeding cylinder 32 drives the mounting bracket 31 to move downward until the bottom end of the mounting bracket 31 is close to the rotating cross 5. At this time, the motor 34 will drive the feeding plate 33 to rotate, and the feeding plate 33 will be inserted into the gap between two adjacent rubber sealing rings during the rotation process, and as the rotation process progresses, the rubber sealing ring below will be pushed and moved downward into the first limiting groove 72 and the second limiting groove 82, thereby realizing automatic feeding of the rubber sealing ring, which is beneficial to improving the testing efficiency.

[0053] The working principle of the present invention is as follows: Figure 1-Figure 8As shown, in the initial state, the rubber sealing ring to be tested is inserted into the first limiting groove 72 and the second limiting groove 82, and the push-pull cylinder 6 can drive the rotating sleeve 61 to move downward, and drive the test slider 7 to slide toward each other along the first sliding groove 51 through the connecting rod 62, so as to start the tensile deformation test of the rubber sealing ring from both ends. In this process, the rubber sealing ring that begins to deform will drive the follower slider 8 to slide synchronously, and the distance sensor 53 is used to monitor the displacement distance change of the follower slider 8 during the deformation process in real time, so as to feedback and analyze the tensile strength of the rubber sealing ring. When the tensile test angle needs to be adjusted, the rotating cross 5 can be rotated by the lever 55 until it rotates to the preset tensile angle, so as to realize the tensile test process of the rubber sealing ring at different angles. When the follow-up slider 8 slides accordingly with the deformation process of the rubber sealing ring, the follow-up slider 8 will synchronously drive the spur rack 83 to perform linear displacement. During the displacement process, the spur rack 83 will drive the matching gear 432 to rotate. The matching gear 432 will drive the turntable 43 to rotate through the central axis 431. When the turntable 43 rotates, it will utilize the sliding cooperation between the inclined slide groove 434 and the sliding pin 463 to drive the sliding block 46 to synchronously slide radially along the sliding groove 45, so that the arc pointer 461 indicates on the marked scale lines 44 of different diameters. The tester can intuitively and vividly obtain the tightness of the rubber sealing ring when it expands in annular direction through the reading of the marked scale lines 44, so that the transmission cooperation between the follow-up slider 8, the turntable 43 and the sliding block 46 can be used to realize two different test simulation processes of linear stretching and annular expansion of the rubber sealing ring. When the rubber sealing ring needs to be replaced, the loading cylinder 32 drives the mounting bracket 31 to move downward until the bottom end of the mounting bracket 31 is close to the rotating cross 5. At this time, the motor 34 will drive the loading plate 33 to rotate. During the rotation process, the loading plate 33 will be inserted into the gap between two adjacent rubber sealing rings, and along with the rotation process, the lower rubber sealing ring will be pushed downward into the first limiting groove 72 and the second limiting groove 82, thereby realizing automatic loading of the rubber sealing ring.

[0054] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
