Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a gate tilting and swinging test tooling. Background Technology

[0002] When a gate tilts and swings, it is subjected to a combination of static and dynamic forces, which may damage its internal structure. The static force is mainly the component of gravity, while the dynamic force is mainly inertial force. To conduct quality inspection of the gate, it is necessary to simulate the working conditions as much as possible and perform tilting and swinging tests on it.

[0003] When the gate is placed on the test bench during the test, it is prone to displacement. It needs to be clamped and fixed with tooling to prevent the gate from falling off the test bench and causing safety hazards. However, there is currently no dedicated tooling, and the tooling design has high requirements, such as rigidity and stability. Utility Model Content

[0027] Please see Figures 1 to 5 As shown, this embodiment provides a gate tilting and swinging test fixture. The gate 3 is cylindrical. The gate tilting and swinging test fixture includes a fixture frame 1. The gate 3 is placed vertically on the fixture frame 1. The bottom of the fixture frame 1 is provided with a plurality of bottom corner mounting plates 2, which are fixed to the test bench.

[0028] The tooling frame 1 includes a first longitudinal bar 11, a second longitudinal bar 12, a first transverse bar 13, a second transverse bar 14, and a detachable diagonal brace. The two first longitudinal bars 11 are arranged in parallel and spaced apart, and the lower circumferential surface of the gate 3 is supported by the two first longitudinal bars 11. The two second longitudinal bars 12 are arranged in parallel and spaced apart, and the upper circumferential surface of the gate 3 is limited by the two second longitudinal bars 12. The two first transverse bars 13 are arranged in parallel and spaced apart, and the lower surfaces on both sides of the gate 3 are limited by the two first transverse bars 13. The second transverse bar 14 cooperates with the diagonal brace to limit the upper surfaces on both sides of the gate 3.

[0029] Thus, the gate 3 is supported and limited by the tooling rack 1 and stabilized on the test bench to meet the test requirements; the tooling rack 1 has a simple and reliable structure, can effectively balance the tilting and swaying forces, and has good rigidity and stability.

[0030] In at least one embodiment, the tooling rack 1 further includes a bottom frame 15, and the bottom frame 15 is welded to the first longitudinal baffle 11, the second longitudinal baffle 12, the first transverse baffle 13, and the second transverse baffle 14 through a plurality of support pipes 16 to construct a plurality of triangular frame structures.

[0031] Among them, by building a triangular frame structure with the support pipes 16, the stability of the structure can be ensured most simply.

[0032] Furthermore, the diagonal brace includes a first diagonal brace pipe 17 and a second diagonal brace pipe 18, and the first diagonal brace pipe 17 and the second diagonal brace pipe 18 are combined in an "inverted V" shape.

One end of the second diagonal brace pipe 18 is bolted to the middle of the first diagonal brace pipe 17, and the other end of the second diagonal brace pipe 18 is bolted to the support pipe 16 connecting the other second longitudinal baffle 12.

[0033] Among them, the diagonal brace in an "inverted V" shape and with detachable connections facilitates the loading and unloading of the gate 3 and ensures the stability of the gate 3 during loading, preventing the gate 3 from swaying back and forth.

The bottom angle mounting plate 2 is provided with reinforcing ribs 21 welded to at least one side of the bottom frame 15, and the bottom angle mounting plate 2 is provided with a plurality of kidney-shaped holes 22 for installing bolts.

[0036] Optionally, the tooling rack 1 is built by a plurality of rectangular pipes.

[0037] Among them, the rectangular pipes have high bending and torsional resistance, are convenient for welding and forming here, have low cost and high reliability.

[0038] In summary, the gate tilting and swaying test tooling has the following advantages:

[0039] 1) Multiple triangular frame structures are formed on the tooling rack 1, which ensures a simple structure while having good rigidity and stability and can effectively bear large tilting and swaying forces;

[0040] 2) Through the bottom angle mounting plate 2 and the reinforcing ribs 21 thereon, the stress concentration phenomenon is effectively reduced;
