Description

Technical Field

[0001] The present invention belongs to the technical field of testing fixtures, and more specifically, relates to a fast clip fixture. Background Art

[0002] Railway rails are components that support locomotives and guide the direction of train travel. The rails are fixed to the sleepers on the roadbed by elastic fasteners, and the elastic fasteners are mainly fast spring clip fasteners. The spring clips bend and twist after installation, generating a clamping pressure on the rails, which effectively ensures a reliable connection between the rails in the long term, maintains the smoothness of the track as much as possible, prevents the rails from moving longitudinally and transversely relative to the sleepers, ensures the normal track gauge, and thus ensures the safety of rail vehicles.

[0003] The existing fast clip fatigue test and buckle pressure tooling uses different tooling to install the test clip, and usually adopts casting or integral welding followed by machining slots to receive the clip, which has the problems of heavy weight and obstruction of the experimenter's observation of the dynamic changes of the clip. Due to the excessive emphasis on easy loading and unloading, especially for Figure 5 The fast clip series shown in the figure is designed for structure, but the adaptability of tooling is not strong and the testing cost is increased.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a fast spring clip tool is provided to achieve the purpose of having more practical value. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a fast spring clip tool to solve Figure 5 The fast spring clip series test tooling shown is heavy, obstructing the experimenter's observation of the dynamic changes of the spring clip during the test, and the tooling has poor adaptability, which increases the test cost.

[0006] The purpose and effect of the fast clip tooling of the present invention are achieved by the following specific technical means:

[0007] A fast spring clip tooling includes a tooling body, which is composed of a pad, a top plate and two vertical plates. The pad and the top plate are connected by two parallel vertical plates to form an "II" shape. A first inclined block is provided on the pad located on the outside of the two vertical plates, and a second inclined block is provided on the bottom of the top plate located on the outside of the two vertical plates. The inclined surfaces of the first inclined block and the second inclined block are oriented in corresponding directions, and the first inclined block can slide on the outside of the vertical plates. An adjustment mechanism for adjusting the position of the first inclined block is provided on the pad.

[0008] Furthermore, the adjustment structure includes a fixing bolt, a side seat is provided at the end of the pad, the fixing bolt passes through the side seat and abuts against the first inclined block, and the fixing bolt is threadedly connected to the side seat.

[0009] Furthermore, the second oblique block is detachably connected to the top plate, and mounting bolts are provided on the top plate, and the mounting bolts pass through the top plate and are connected to the second oblique block.

[0010] Furthermore, the length of the top plate is smaller than the length of the backing plate, so that the front side of the backing plate extends out a portion that is not blocked by the top plate in the vertical direction.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] Through the "Ⅱ"-shaped one-piece tooling body design, the two sides of the fast clip are clamped between the first and second bevel blocks, with the bend against the bottom of the top plate. The test pressure block presses down from above on the nose of the fast clip in the middle, fully simulating the stress direction at each contact point when the fast clip is buckled on the railway rail. The test results are more accurate and better meet actual usage requirements. The tooling body design also has higher structural strength, less material, and is lightweight. Only two bevel blocks need to be replaced to adapt to different types of fast clip tests, making it easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Example 1:

[0024] As attached Figure 1 To the attached Figure 5 As shown:

[0025] The present invention provides a fast spring clip fixture, including a fixture body, which is composed of a pad 2, a top plate 7 and two vertical plates 6. The pad 2 and the top plate 7 are connected by two parallel vertical plates 6 to form a "Ⅱ" shape, which increases the structural strength of the fixture body. During the test, the pad 2 is installed on the bearing plate 1 of the test equipment, so that the fast spring clip 10 corresponds to the pressure block tested above. The pad 2 is provided with a first oblique block 4 on the outside of the two vertical plates 6, and the bottom of the top plate 7 is provided with a second oblique block 8 on the outside of the two vertical plates 6. The oblique surfaces of the first oblique block 4 and the second oblique block 8 are oriented in the corresponding directions. Figure 1 As shown, the first oblique block 4 can slide forward and backward on the outside of the vertical plate 6, and an adjustment mechanism for adjusting the position of the first oblique block 4 is provided on the pad 2;

[0026] When the cam 11 is in the closed position, the cam 12 is in the closed position, and the cam 13 is in the closed position, so that the cam 13 is in the closed position, and the cam 13 is in the closed position, so that the cam 13 is in the closed position, and the cam 13 is in the closed position, so that the cam 13 is in the closed position, and the cam 13 is in the closed position, so that the cam 13 is in the closed position, and the cam 13 is in the closed position, so that the cam 13 is in the closed position, and the cam 13 is in the closed position, so that the cam 13 is in the closed position, Figure 4 As shown, the pressing block presses the fast clip 10 downward, simulating the fast clip being fastened to the railway rail. The stress direction at each contact point is consistent with the actual stress on the rail, making the test more accurate. At the same time, the dynamic changes of the fast clip 10 can be observed more clearly, and the main structure of the tooling is more stable during the test.

[0027] The inclined surfaces of the first inclined block 4 and the second inclined block 8 respectively contact the upper and lower surfaces of the toe section of the fast clip 10. Then, the contact between the lower surface of the top plate 7 and the upper surface of the tail section of the fast clip 10 and the pressure of the fastening bolt 5 form a three-point "clamping" posture for the fast clip 10, so that the fast clip can be accurately positioned and fixed after installation.

[0028] Among them, the second oblique block 8 is detachably connected to the top plate 7, and a mounting bolt 9 is provided on the top plate 7. The mounting bolt 9 passes through the top plate 7 and is connected to the second oblique block 8. Through the setting of the mounting bolt 9, the second oblique block 8 is easy to replace, and the corresponding second oblique block 8 can be replaced according to different models of fast spring bars 10.

[0029] The length of the top plate 7 is smaller than that of the backing plate 2 , so that the front side of the backing plate 2 extends out a portion that is not blocked by the top plate 7 in the vertical direction.

[0030] Example 2: The difference between this example and Example 1 is that a sliding groove corresponding to the first inclined block 4 is provided on the pad 2, and the first inclined block 4 is slidably clamped in the sliding groove, and the first inclined block 4 is pushed to slide by the tightening bolt 5, so that the first inclined block 4 is close to the second inclined block 8.

[0031] Embodiment 3: The difference between this embodiment and embodiment 1 is that the end of the fastening bolt 5 is rotatably connected to the first inclined block 4. By rotating the fastening bolt 5 to drive the first inclined block 4 to slide back and forth, bidirectional control can be achieved.

[0032] When using:

[0033] After the fixture body is mounted on the load plate 1 of the test equipment platform and the test equipment is activated, the pressure block of the test head on the test equipment presses against the upper surface of the nose portion of the fast clip 10 in the middle, performing an up and down reciprocating motion according to a preset test program. The instrument configured with the test equipment records the corresponding clip deformation-force curve, which can be used to test the fatigue performance and buckle force of the fast clip 10.

[0034] The embodiments of the present invention are presented for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described in order to better illustrate the principles of the invention and its practical application and to enable those skilled in the art to understand the invention and design various embodiments with various modifications as suited for specific applications.
