Description

Technical Field

[0001] The utility model relates to the field of retaining ring strength detection, in particular to a retaining ring compression strength test tool. Background Art

[0002] The compressive strength test tooling of retaining rings originates from the requirements for the quality and reliability of mechanical parts. In the field of mechanical engineering, retaining rings are a common component used to fix bearings or other mechanical elements to play a role in positioning and preventing axial movement. Due to the importance of retaining rings in mechanical assembly, their quality and strength are crucial and directly related to the performance and safety of mechanical equipment. In order to ensure that the quality of retaining rings meets the requirements, compressive strength tests are required to evaluate their stability and reliability when under pressure. The compressive strength test tooling is a tool used to support and load retaining rings and simulate the pressure on retaining rings during the test. Its design and manufacture are of great significance.

[0003] After searching, it was found that a test fixture for a steel wire retaining ring for a shaft is disclosed in the announcement number: CN208109364U, which includes a base, and the sleeve and the mandrel are coaxially arranged on the base, and the two can move relative to each other along the axis. The mandrel includes multiple working sections, and a contraction section for shrinking the steel wire retaining ring for the shaft is provided between adjacent working sections. The sleeve and the mandrel are coaxially arranged on the base, and the two can move relative to each other along the axis. The mandrel and the sleeve always remain coaxial during movement, and no manual adjustment is required, thereby improving the reliability of the test. The original single working section on the mandrel is extended into multiple working sections, and the length of each working section is not less than the length required by the test, thereby increasing the sliding distance of the steel wire retaining ring for the shaft on the mandrel, and a contraction section for shrinking the steel wire retaining ring for the shaft is provided between each working section. During the test, the shaft wire retaining ring can be expanded and contracted multiple times with one clamping, which reduces the number of clamping times. The test fixture in this application is reliable for testing retaining rings of specific sizes, but when testing retaining rings of different sizes, the corresponding equipment needs to be replaced, and its applicability is low.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0023] Specifically, when using the retaining ring compressive strength test tool, first place the steel ring to be tested on the cushion block 10 and directly below the support shell 3, then start the motor 4 according to the size of the retaining ring, and then the motor 4 drives the two tooth plates 6 to move, and then the two tooth plates 6 respectively drive the corresponding pressure blocks 7 to move, so that the two pressure blocks 7 are respectively aligned with the retaining rings, and after alignment, start the cylinder 2. At this time, the cylinder 2 pushes the support shell 3 until the pressure block 7 presses and fixes the retaining ring, and then start the cylinder 2 8. The cylinder 2 8 drives the stop rod 9 to limit the position of the retaining ring to prevent the displacement of the retaining ring due to pressure during the experiment, which leads to inaccurate experimental results and the need to repeat the experiment. The structure can indirectly drive the pressure block 7 to move through the motor 4, so that retaining rings of different sizes can be pressed and fixed.

[0024] Reference Figure 1 - Figure 3 The protection component includes a hinge 13 and an explosion-proof glass door 14, one end of the hinge 13 is fixedly connected to one side of the outer wall of the explosion-proof glass door 14, and the other end of the hinge 13 is fixedly connected to one side of the outer wall of the housing 1;

[0025] Specifically, when using the retaining ring compression strength test tool for conducting experiments, closing the explosion-proof glass door 14 can prevent excessive pressure during the retaining ring compression strength test, causing the retaining ring to collapse and fly, thereby causing harm to the staff. The explosion-proof glass door 14 in this structure has higher impact resistance and safety. Even if it is impacted by external force, the glass will not form sharp fragments after breaking, reducing the risk of personal injury.

[0026] Reference Figure 1 - Figure 3A handle 15 is fixedly connected to one side of the outer wall of the explosion-proof glass door 14, a motor 2 16 is fixedly connected inside the shell 1, a positive and negative threaded rod 17 is fixedly connected to the output end of the motor 2 16, a slider 18 is threadedly connected to the outer wall of the positive and negative threaded rod 17, a transmission rod 19 is rotatably connected to the bottom of the slider 18, a connecting plate 20 is rotatably connected to the bottom of the transmission rod 19, a square array of wheels 21 is fixedly connected to the bottom of the connecting plate 20, a connecting block 22 is fixedly connected to the top of the connecting plate 20, a sliding column 23 is fixedly connected inside the shell 1, and the outer wall of the sliding column 23 is slidably connected to the inside of the connecting block 22, a slide groove 24 is opened inside the shell 1, and both sides of the outer wall of the connecting block 22 are slidably connected to the inside of the slide groove 24;

[0027] Specifically, when the retaining ring compressive strength test fixture needs to be moved, first start the motor 2 16, the motor 2 16 drives the positive and negative screws 17 to rotate, and then the positive and negative screws 17 drive the slider 18 to move, and then through the transmission rod 19, drive the connecting plate 20 to descend until the wheel 21 touches the ground, and then push the retaining ring compressive strength test fixture. When the device is moved, it can be moved without the aid of additional tools, and it is very convenient to move.

[0028] Working principle: When using the retaining ring compression strength test fixture, first place the test retaining ring on the pad 10, just below the support shell 3, then start the motor 4, the motor 4 drives the gear 5 to rotate, and then drives the two tooth plates 6 to move to the two sides of the support shell 3 respectively, until the pressure block 7 is located just above the retaining ring, and then start the cylinder 2, the cylinder 2 pushes the support shell 3 down, until the pressure block 7 presses the retaining ring, then start the cylinder 2 8, the cylinder 2 8 pushes the stop rod 9 to limit and fix the retaining ring to prevent movement, at this time, the cylinder three 11 can be started to push the pressure block two 12, and the compression strength test of the retaining ring can be carried out. When it is necessary to move the equipment, first start the motor 2 16, and then the motor 2 16 drives the forward and reverse screw rods 17 to rotate. At this time, the rotation of the forward and reverse screw rods 17 drives the slider 18 to move, and then the connecting plate 20 is pushed down through the transmission rod 19, thereby driving the wheel 21 to descend. After the descent is completed, the retaining ring compression strength test fixture can be moved.
