[0003] To ensure the strength of the machined parts, a vibration test is required before assembly. Before conducting the vibration test, a vibration test fixture needs to be made to fix the parts to be tested on the vibration test bench. Utility Model Content

[0004] To address the aforementioned problems, this application provides a vibration clamp.

[0005] The vibration clamp provided in this application adopts the following technical solution:

[0006] A vibration fixture includes a mounting plate fixedly connected to the worktable of a vibration table via a connector. A support plate is provided on the mounting plate, and a baffle is provided circumferentially on the support plate. The baffle and the support plate enclose a receiving space for accommodating a part to be tested.

[0007] Furthermore, a plug is fixedly connected to the side wall of the baffle facing the opening, and the plug corresponds to the insertion hole on the part to be tested.

[0008] Furthermore, the mounting plate is provided with two sets of crossbeams, the top walls of the two sets of crossbeams are fixedly connected to the support plate, and there is a gap between the support plate and the mounting plate.

[0009] Furthermore, the limiting assembly includes a screw, a locking device, a connecting plate, and a limiting block. A hinge seat is provided at the bottom of the support plate. One end of the screw is rotatably connected to the hinge seat. The locking device is mounted on the screw and has a tapered groove. The center line of the tapered groove is collinear with the center line of the screw. The connecting plate is fixedly connected to the end wall of the part to be tested near the opening. A limiting block is provided at the bottom of the connecting plate. The angle between the extension direction of the limiting block and the extension direction of the connecting plate is acute. The limiting block is inserted into the tapered groove, and the side wall of the limiting block fits against the groove wall of the tapered groove.

[0010] Furthermore, the limiting components are provided in multiple sets, and the multiple sets of limiting components are evenly distributed along the direction perpendicular to the opening.

[0011] Furthermore, the baffle is provided with several through holes.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] The precise positioning of the part under test is achieved through the receiving space formed by the support plate and the baffle and the insertion rod-hole matching structure, reducing the error of manual adjustment. Multiple sets of limiting components are evenly distributed along the vertical direction of the opening to form multi-point constraints, which effectively suppresses the lateral displacement of the part during vibration and helps to improve the reliability of test data.

[0014] When limiting different parts to be tested, first insert the insert rod into the insertion hole of the part to be tested, then rotate the screw and tighten the locking device. The locking device moves towards the direction of the screw rotation axis, so that the limiting block is inserted into the conical groove. At this time, the side wall of the limiting block and the groove wall of the conical groove are in contact, thus realizing the limiting of the part to be tested.

[0015] The combination of the insertion rod and the limiting component meets the vibration testing requirements of the fixture for parts of different shapes and specifications, and has high versatility. Attached Figure Description

Detailed Implementation

[0021] The following is in conjunction with the appendix Figure 2-4 This application will be described in further detail.

[0022] This application discloses a vibration clamp.

[0023] Reference Figure 2A vibration fixture includes a mounting plate 3 fixedly connected to the worktable of a vibration table via a connector. A support plate 4 is provided on the mounting plate 3, and a baffle 5 is provided circumferentially on the support plate 4. The baffle 5 and the support plate 4 enclose a receiving space 9 for accommodating a part to be tested 1. An opening 10 is provided on the baffle 5, and a rod 11 is fixedly connected to the side wall of the baffle 5 facing the opening 10. In this embodiment, two rods 11 are provided, and each rod 11 corresponds one-to-one with two insertion holes 2 on the part to be tested 1. A limiting component 6 for limiting the position of the part to be tested 1 is provided on the support plate 4. Multiple sets of limiting components 6 are provided, and these sets are evenly distributed along a direction perpendicular to the opening 10.

[0024] The precise positioning of the part to be tested 1 is achieved through the accommodating space 9 formed by the support plate 4 and the baffle 5, and the cooperation structure of the insertion rod 11 and the insertion hole 2, reducing the error of manual adjustment. Multiple sets of limiting components 6 are evenly distributed along the vertical direction of the opening 10 to form multi-point constraints, which effectively suppresses the lateral displacement of the part during vibration and helps to improve the reliability of test data.

[0025] Reference Figure 2-4 The mounting plate 3 is provided with two sets of crossbeams 12. The top walls of the two sets of crossbeams 12 are fixedly connected to the support plate 4. There is a gap 13 between the support plate 4 and the mounting plate 3. The limiting component 6 includes a screw 61, a locking device 62, a connecting plate 63 and a limiting block 64. The bottom of the support plate 4 is provided with a hinge seat 7. One end of the screw 61 is rotatably connected to the hinge seat 7. The locking device 62 is assembled on the screw 61. A conical groove 8 is opened on the locking device 62. The center line of the conical groove 8 is collinear with the center line of the screw 61. The connecting plate 63 is fixedly connected to the end wall of the part to be tested 1 near the opening 10. A limiting block 64 is provided at the bottom of the connecting plate 63. The angle between the limiting block 64 and the extension direction of the connecting plate 63 is an acute angle. The limiting block 64 is inserted into the conical groove 8. The side wall of the limiting block 64 is in contact with the groove wall of the conical groove 8.

[0026] When limiting different test parts 1, first insert the insertion rod 11 into the insertion hole 2 of the test part 1, then rotate the screw 61 and tighten the locking device 62. The locking device 62 moves towards the direction of rotation of the screw 61, so that the limiting block 64 is inserted into the conical groove 8. At this time, the side wall of the limiting block 64 and the groove wall of the conical groove 8 are in contact, thus realizing the limiting of the test part 1. The combination of the insertion rod 11 and the limiting component 6 meets the vibration testing requirements of the fixture for test parts 1 of different shapes and specifications, and has high versatility.

[0027] Reference Figure 3 The baffle 5 is provided with several through holes 15 to reduce the weight of the vibration clamp.

[0028] The implementation principle of a vibration fixture according to an embodiment of this application is as follows: When limiting different test parts 1, first insert the insertion rod 11 into the insertion hole 2 of the test part 1, then rotate the screw 61 and tighten the locking device 62. The locking device 62 moves towards the direction close to the rotation axis of the screw 61, so that the limiting block 64 is inserted into the conical groove 8. At this time, the side wall of the limiting block 64 and the groove wall of the conical groove 8 are in contact, thus realizing the limiting of the test part 1. The combination of the insertion rod 11 and the limiting component 6 meets the vibration testing requirements of the fixture for test parts 1 of different shapes and specifications, and has high versatility.
