[0002] Impact refers to the transient load a structural system is subjected to. Impact testing simulates the transportation shock, external force shock, collision shock and even explosion shock that a product may experience during its life cycle, in order to verify whether the product can work normally after the impact and obtain the product's impact resistance performance.

[0003] At present, during impact tests, it is necessary to use a fixture to clamp and fix the test piece. For example, the Chinese invention patent with publication number: CN111609983A is named: A universal vibration and impact test fixture for rotary mechanism products, including a mounting plate, an intermediate cylinder, an adapter flange and an end support assembly. The mounting plate and the intermediate cylinder are welded to increase the natural frequency of the fixture body; the adapter flange and the end face of the intermediate cylinder are connected by screws. The flange can be replaced when testing different products, and the rotating flange can change the test direction. The end support assembly consists of a connector and a support member, which is fastened to the intermediate cylinder and used to fix the end of the product during testing, thereby improving the approximation of the product to the actual use environment. By replacing the adapter flange, this device can realize vibration and impact testing of rotary mechanism products and has universality.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] In order to solve the technical problem in the prior art that the impact test fixture can only impact the specimen 400 at a fixed angle, thereby causing the fixture to be unable to adapt to the continuous change of the test angle, the present invention provides a rotating structure impact test fixture. By setting a first clamping component 200, it can not only achieve stable clamping of the specimen 400, but also utilize the detachable connection between the locking member and the first swinging body 310 to enable the specimen 400 to be rotated within a first preset angle and then fixed, so as to meet the needs of continuously changing the inclination angle of the specimen 400 and meet the needs of impact tests at different inclination angles. The structure is simple and the operation is convenient.

[0021] See also Figures 1 to 5 , Figure 1 This is a structural schematic diagram of a rotating structure impact test tool in one embodiment of the present invention. The rotating structure impact test tool includes a base 100, a first clamping assembly 200 and a first swinging assembly 300.

The first swinging assembly 300 includes a first swinging body 310 and a first locking member 320. One end of the first swinging body 310 is connected to the first clamping assembly 200, and the other end can swing within a first preset angle relative to the base 100. The first locking member 320 is connected to the base 100 and can be detachably connected to the first swinging body 310 to limit the rotation of the specimen 400 relative to the base 100.

[0022] In this device, by setting up the first clamping assembly 200, stable clamping of the specimen 400 can be achieved. At the same time, by utilizing the detachable connection between the locking member and the first swinging body 310, the specimen 400 can be rotated within a first preset angle and fixed to meet the needs of continuously changing the inclination angle of the specimen 400 to meet the needs of impact tests at different inclination angles. The structure is simple and the operation is convenient.

[0023] Furthermore, after the first clamping assembly 200 completes the clamping and installation of the specimen 400, the specimen 400 rotates relative to the base together with the first swinging body 310 to achieve continuous change in the inclination angle of the specimen 400 to meet the needs of impact tests at different inclination angles. This can solve the technical problem in the prior art that the impact test fixture can only impact the specimen 400 at a fixed angle, thereby causing the fixture to be unable to adapt to the continuous change of the test angle.

[0040] By utilizing the cooperation between the second locking member 350 and the first locking hole and the first connecting hole, the tilt angle of the test piece 400 relative to the base 100 can be continuously changed.

[0041] Furthermore, the first locking member 320 and the second locking member 350 here are both common and easy-to-purchase locking pins on the market. One end of the locking pin is inserted into the first locking hole or the second locking hole 361 and the first connecting hole or the second connecting hole 312 in sequence, which can realize the rapid locking and adjustment of the first swinging member, with a simple structure and simple operation.

The second clamping hole 510 has a clamping state for clamping the specimen 400 and an open state for releasing the specimen 400, and the axis of the second clamping hole 510 is collinear with the axis of the first clamping hole 210. The second swinging component 600 includes a second swinging body 610, one end of the second swinging body 610 is connected to the second clamping component 500, and the second clamping component 500 can rotate around the axis of the first clamping hole 210 relative to the first swinging body 310, and the other end of the second swinging body 610 is connected to the base 100 and can swing relative to the base 100 within a first preset angle.

[0051] The second arc-shaped abutting end 611 of the second swinging body 610 cooperates with the third arc-shaped groove on the second connecting seat 620 to realize the rotational connection between the second swinging body 610 and the base 100, and is used to adjust and position the sliding of the second connecting seat 620, the second swinging body 610 and the second clamping assembly 500 relative to the pad 800.

By locating the first clamping assembly 200 and the second clamping assembly 500 at different heights, the specimen 400 can be used when it is tilted.

[0061] Furthermore, the sliding connection between the fixing rod 700 and the cushion block 800 can enhance the connection strength between the cushion block 800 and the base 100 .

[0064] In order to better understand the present invention, the following Figures 1 to 5 The technical solution of the present invention is described in detail: The base 100 is provided with a first clamping assembly 200, which has a first clamping hole 210 for clamping or releasing the specimen 400. One end of a first oscillating member 310 is connected to the first clamping assembly 200, and the other end can swing relative to the base 100 within a first preset angle, so as to enable the specimen 400 to rotate relative to the base 100 by the first preset angle. A first locking member 320 is connected to the base 100 and can be detachably connected to the first oscillating member 310 to restrict the rotation of the specimen 400 relative to the base 100. Compared with the prior art, the provision of the first clamping assembly 200 can achieve stable clamping of the specimen 400. At the same time, the detachable connection between the locking member and the first oscillating member 310 allows the specimen 400 to be rotated and fixed within the first preset angle, thereby meeting the requirements of continuously changing the inclination angle of the specimen 400 and satisfying the requirements of impact tests at different inclination angles. The structure is simple and easy to operate.

[0065] The specific working process of the present invention is that when the inclination angle of the specimen 400 for the impact test is 0°, the user first adjusts the first swinging body 310 so that the plane where the axis of the first clamping hole 210 is located is parallel to the plane where the base 100 is located, and then locks the first locking piece 320 with the first connecting seat 360, and installs one end of the specimen 400 in the first clamping hole 210 and locks it, and then reasonably selects the number of pads 800 to be one, and adjusts the second swinging body 610 so that the axis of the second clamping hole 510 is colinear with the axis of the first clamping hole 210, and finally locks the third locking piece 630 with the second connecting seat 620, and installs the other end of the specimen 400 in the second clamping hole 510 and locks it. At this time, the specimen 400 is stably fixed and installed, and the user can perform the impact test.

[0066] Furthermore, when the inclination angle of the specimen 400 for the impact test is 10°, the user first adjusts the first swinging body 310 so that the angle between the plane where the axis of the first clamping hole 210 is located and the plane where the base 100 is located is 10°, then locks the first locking piece 320 with the first connecting seat 360, and installs one end of the specimen 400 in the first clamping hole 210 and locks it, then reasonably selects the number of pads 800 to be two, and adjusts the second swinging body 610 so that the axis of the second clamping hole 510 is colinear with the axis of the first clamping hole 210, finally locks the third locking piece 630 with the second connecting seat 620, and fine-tunes the position of the second connecting seat 620 relative to the second swinging seat, installs the other end of the specimen 400 in the second clamping hole 510 and locks it. At this time, the specimen 400 is stably fixed and installed, and the user can perform the impact test.

[0067] The device, through the above structure, can solve the technical problem in the prior art that the impact test fixture can only impact the test piece 400 at a fixed angle, thereby causing the fixture to be unable to adapt to continuous changes in the test angle.

[0068] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
