Description

Technical Field

[0001] This utility model relates to the field of fastening fixture technology, and in particular to a fastening fixture for mounting a horizontal vibration table. Background Technology

[0002] In the reliability horizontal axial vibration test, the horizontal vibration table mounting fixture is a key tool for fixing the test prototype to the vibration platform. Its main function is to ensure that the prototype will not collide with or fall off the platform due to vibration during the test, thereby protecting the safety of the vibration table and sensors.

[0003] However, existing fixing methods usually rely on direct bolt fixing. For larger test specimens, due to the long bolts, insufficient tightening is easily encountered during vibration, causing the specimen to fall off and damage the vibration table or test sensor, which threatens the accuracy and safety of the experiment. In addition, each time the test specimen is replaced, it is necessary to reposition and manually adjust the fixing nuts and crossbars. This process is time-consuming and labor-intensive, greatly reducing the testing efficiency.

[0004] Therefore, to solve the above problems, we propose a horizontal vibration table mounting and fastening fixture. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies, improve the reliability and convenience of fixing devices, and enhance testing efficiency and accuracy.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] The main body of the adjustment bracket is a vertical arm, and the vertical arm has screw grooves on both ends;

[0009] The fixed crossbar has T-shaped grooves extending through both ends along its narrow side in the length direction;

[0010] The adjusting fastening assembly includes a through-hole threaded rod, a nut, and an inner threaded fastener. The through-hole threaded rod is located in the screw groove, the nut is sleeved on the through-hole threaded rod and located on the rear end face of the vertical arm, and the inner threaded fastener is sleeved on the through-hole threaded rod and located on the front end face of the vertical arm.

[0011] Furthermore, there are two adjustment brackets, and the bottom of each adjustment bracket is provided with a mounting base. The mounting base is provided with a threaded through hole, and the mounting base is fixed to the horizontal vibration platform by bolts connecting to the threaded through hole.

[0012] Furthermore, the fixed crossbar is horizontal with the horizontal vibration platform, and the fixed crossbar is arranged vertically at one end face of the two vertical arms.

[0013] Furthermore, the diameter of the screw groove matches the diameter of the threaded rod through the hole.

[0014] Furthermore, an anti-slip pad is provided on the inner side of the nut, and the anti-slip pad is sleeved on the outer periphery of the threaded rod through the hole, located between the nut and the vertical arm.

[0015] Furthermore, the T-slot is larger than the inner threaded fastener, and the distance between the inner threaded fastener and the vertical arm matches the baffle portion on the outer side of the T-slot.

[0016] The horizontal vibration table mounting and fastening fixture proposed in this utility model significantly improves the reliability, safety, and operational efficiency of vibration testing through its innovative structural design, and has the following outstanding advantages:

[0017] 1. Enhance fixed reliability and avoid test accidents.

[0018] The design employs a connection structure with a double-adjustable bracket and a T-slot crossbar, along with an anti-slip pad design, to effectively solve the problem of long screw vibration loosening, prevent the prototype from being thrown off, and protect the vibration table and sensor safety.

[0033] Example 1

[0034] like Figure 1-3 As shown, this utility model provides a technical solution: a horizontal vibration table mounting and fastening fixture. The fastening fixture is designed to provide a stable and reliable mounting and fixing method for the prototype under test on the horizontal vibration table, so as to ensure that the prototype will not be displaced or loosened during the vibration test, thereby ensuring the accuracy and reliability of the test data.

[0035] The fixed fixture mainly includes an adjusting bracket 1 and a fixed crossbar 2. The adjusting bracket 1 and the fixed crossbar 2 are connected and fixed by adjusting fastening components 3. The adjusting bracket 1 serves as the main support and adjustment body of the entire fixture. Its main body is designed as a vertical arm 11. The vertical arm 11 is made of high-strength metal material, such as stainless steel or aluminum alloy. The vertical arm 11 has screw grooves 12 on both ends. The screw grooves 12 need to be machined to be relatively smooth to reduce the friction of the threaded rod 31 during the sliding process, while ensuring that the threaded rod 31 can move smoothly in the screw grooves 12, so as to realize the flexible adjustment of the fixture height.

[0036] The fixed crossbar 2 is a component used to directly fix the sample to be tested. T-slots 21 are provided at both ends along its narrow side in the length direction. The T-slots 21 not only provide space for the installation and sliding of the inner threaded fastener 33, but also effectively prevent the inner threaded fastener 33 from detaching from the fixed crossbar 2 in the horizontal direction, thereby enhancing the overall structural stability of the fixture.

[0037] The adjusting fastening assembly 3 is a key component connecting the adjusting bracket 1 and the fixed crossbar 2. It includes a through-hole threaded rod 31, a nut 32, and an inner threaded fastener 33. The through-hole threaded rod 31 is located in the screw groove 12, and its diameter matches the width of the screw groove 12 to ensure that the through-hole threaded rod 31 can slide stably in the groove without excessive shaking. The nut 32 is sleeved on the through-hole threaded rod 31 and is located on the rear end face of the vertical arm 11. By rotating the nut 32, pressure can be applied to tightly fix the adjusting bracket 1 and the fixed crossbar 2 together. The inner threaded fastener 33 is sleeved on the through-hole threaded rod 31 and is located on the front end face of the vertical arm 11. Its shape is adapted to the T-slot 21, so that it can be smoothly embedded in the T-slot 21 and achieve sliding adjustment.

[0038] Example 2

[0039] like Figure 1-3 As shown, in this embodiment, there are two adjusting brackets 1. This double bracket design can provide more balanced support force and ensure that the fixed crossbar 2 remains stable during horizontal vibration. The bottom of the adjusting bracket 1 is provided with a mounting base 13, and the mounting base 13 is provided with a threaded through hole 14. The mounting base 13 is fixed to the horizontal vibration platform by bolts to the threaded through hole 14. The shape and size of the mounting base 13 are designed according to the installation interface of the horizontal vibration platform to ensure that it can fit tightly with the platform and provide a reliable fixing effect. The mounting base 13 and the adjusting bracket 1 are connected by welding or bolts.

[0040] The fixed crossbar 2 is kept horizontal with the horizontal vibration platform. The fixed crossbar 2 is arranged vertically at one end of the two vertical arms 11 to form a stable frame structure, which effectively resists the lateral force generated by horizontal vibration.

[0041] The diameter of the screw groove 12 is precisely calculated and designed to match the through-hole threaded rod 31, which ensures that the through-hole threaded rod 31 can slide freely in the groove and prevents it from generating excessive displacement during vibration, thus ensuring the adjustment accuracy and stability of the fixture.

[0042] An anti-slip pad 34 is provided on the inner side of the nut 32. The anti-slip pad 34 is sleeved around the threaded rod 31 through the hole and is located between the nut 32 and the vertical arm 11. The anti-slip pad 34 is made of rubber or silicone and has good elasticity and friction. It can effectively prevent the nut 32 from loosening during vibration and enhance the fixing effect of the fixture. At the same time, the anti-slip pad 34 can also play a buffering role, reducing the friction and wear between the nut 32 and the vertical arm 11 and extending the service life of the fixture.

[0043] The T-slot 21 is larger than the inner threaded fastener 33. This design provides sufficient space for the inner threaded fastener 33 to slide within the T-slot 21, while ensuring that the inner threaded fastener 33 can move within the slot to adjust the width of the fixture. The distance between the inner threaded fastener 33 and the vertical arm 11 matches the baffle portion on the outer side of the T-slot 21. This precise matching design ensures that the inner threaded fastener 33 will not interfere with the T-slot 21 during sliding, while also ensuring a firm and reliable connection between the fixed crossbar 2 and the adjusting bracket 1.

[0044] Workflow: When using a horizontal vibration table to set up and fasten fixtures;

[0045] First, use bolts to fix a vertical component to the platform, parallel to the vibration direction of the horizontal vibration table, through the two screw holes at the bottom;

[0046] Pass the threaded rod 31 through the screw groove 12 of the vertical arm 11 of the vertical fixing assembly, and screw on the inner threaded fixing piece 33.

[0047] Then insert the inner threaded fastener 33 into one end of the fixed crossbar 2, and put the anti-slip pad 34 on the outside of the vertical arm 11 and tighten the nut 32 to fix it.

[0048] The other end of the fixed crossbar 2, like the first end, passes through the through-hole threaded rod 31, and is screwed on with the inner threaded fastener 33, anti-slip pad 34 and nut 32 to connect to another vertical fixing component;

[0049] The vertical fixing component connected to the other end of the fixed crossbar 2 is fixed to the right side of the platform by bolts through the two screw holes at the bottom.

[0050] By adjusting the nuts 32 that are fixed at both ends of the fixed horizontal bar 2 to the screw grooves 12 of the vertical fixed component 11, the vertical height of the fixture can be adjusted in the grooves of the vertical fixed component 11.

[0051] The left and right width of the fixture can be adjusted by sliding the inner threaded fastener 33 in the T-slot 21 of the fixed crossbar 2.

[0052] Place the sample to be tested under the fixed crossbar 2, tighten the fixing nuts 32 at both ends, and compact the sample;

[0053] Finally, the test data recording on the horizontal vibration table was completed.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
