Description

Technical Field

[0001] This invention relates to the field of vibration testing technology, and in particular to a vibration fixture and vibration testing equipment. Background Technology

[0002] When conducting vibration tests on products, it is generally necessary to assess vibration at different levels in the X, Y, and Z directions. Most vibration testing equipment uses a one-dimensional uniaxial vibration table. To achieve the required vibration at different levels in the three directions, existing vibration fixtures typically involve adjusting the mounting orientation of the test sample or adjusting the excitation source orientation of the uniaxial vibration table. However, changing the orientation of the vibration fixture may introduce unpredictable risks of damage and malfunction to the test sample, and the changeover time is also relatively long, significantly impacting the efficiency of product vibration testing. Summary of the Invention

[0003] Therefore, it is necessary to provide a vibration fixture and vibration testing equipment to address the problem that changing the direction of the vibration fixture may bring unpredictable damage and failure to the test sample, and the change time is also relatively long, which greatly affects the vibration test efficiency of the product.

[0004] The technical solution is as follows:

[0005] On the one hand, a vibration clamp is provided, comprising:

[0006] A fixed body, wherein a first mounting part and a second mounting part are provided at intervals on one side of the fixed body;

[0007] A supporting body has a first mounting groove and a second mounting groove spaced apart on one side near the fixed body. The first mounting part is limited to the inner wall of the first mounting groove, and the second mounting part is limited to the inner wall of the second mounting groove, so that the fixed body is inclined relative to the supporting body; and

[0008] A first locking element is used to lock the fixed body and the supporting body in a tight fit.

[0009] The technical solution will be further explained below:

[0010] In one embodiment, the distance between the first mounting groove and the side of the support body away from the fixed body is a first height, and the distance between the second mounting groove and the side of the support body away from the fixed body is a second height, the second height being greater than the first height. Both the first mounting groove and the second mounting groove penetrate the support body. The two opposing inner sidewalls of the first mounting groove are set at an angle, and the two opposing inner sidewalls of the second mounting groove are set at an angle. The first mounting portion includes a first outer cylindrical surface, which is matched with the inner sidewall of the first mounting groove. The second mounting portion includes a second outer cylindrical surface, which is matched with the inner sidewall of the second mounting groove.

[0011] In one embodiment, the number of first mounting portions is at least one, and each of the first mounting portions is spaced apart along the extension direction of the first mounting groove; the number of second mounting portions is at least one, and each of the second mounting portions is spaced apart along the extension direction of the second mounting groove.

[0012] In one embodiment, the first mounting portion has a first hollow hole, and the second mounting portion has a second hollow hole.

[0013] In one embodiment, the first outer cylindrical surface is tangent to both inner sidewalls opposite to the first mounting groove, and the first outer cylindrical surface is tangent to both inner sidewalls opposite to the second mounting groove.

[0014] In one embodiment, the vibration clamp further includes an adjustment component, which is installed in the second mounting slot and engages with the second outer cylindrical surface to adjust the tilt angle of the fixed body relative to the supporting body.

[0015] In one embodiment, the adjustment assembly includes a shim, a crimping member, and a second locking member. The shim is disposed on the bottom wall of the second mounting groove, the crimping member passes through the second mounting groove and abuts against the shim, and the second locking member is used to lock the crimping member to the support body.

[0016] In one embodiment, both ends of the crimping member are provided with flange portions, the flange portions are provided with first fixing grooves, the support body is provided with second fixing grooves, the second fixing grooves penetrate the support body, the two ends of the second fixing grooves are respectively connected to the two first fixing grooves, and the second locking member is provided as a second bolt, the second bolts are provided through the second fixing grooves and the two first fixing grooves, so as to lock the two flange portions to the support body.

[0017] In one embodiment, the support body is provided with two extensions extending toward the side closer to the fixed body, each of the two extensions being provided with a third fixing groove, and the support body being provided with a fourth fixing groove that penetrates the support body. The two ends of the fourth fixing groove are respectively connected to the two third fixing grooves. The first locking member is provided as a first bolt that passes through the fourth fixing groove and the two third fixing grooves to lock the two extensions to the support body.

[0018] On the other hand, a vibration testing device is provided, including a uniaxial excitation vibration table and the vibration fixture, wherein the vibration fixture is fixed on the uniaxial excitation vibration table.

[0019] In the vibration fixture and vibration testing equipment described in the above embodiments, the support body is fixed on a uniaxial excitation vibration table, allowing the uniaxial excitation vibration table to apply vibration excitation along the normal direction of the side of the support body closest to the fixed body. Simultaneously, the test sample is fixed on the side of the fixed body away from the support body. Because the fixed body is inclined relative to the support body, when the uniaxial excitation vibration table applies vibration excitation to the support body, the test sample on the fixed body can generate vibration responses in three different directions, achieving the required vibration magnitudes in three different directions. Compared to current vibration fixtures, this application, by fixing the test sample to a fixed body inclined relative to the support body, achieves simultaneous vibration response in three directions with a single fixation and application of vibration excitation in one direction. This reduces the need for changing or adjusting the direction of the vibration fixture, reduces the time required for changing the direction of the vibration fixture, shortens the vibration testing cycle, improves the efficiency of the vibration testing, and also reduces the risk of damage and failure of the test sample.

[0027] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0028] like Figure 1 As shown, in one embodiment, a vibration clamp 10 is provided, including a fixed body 100, a support body 200, and a first locking member (not shown). The fixed body 100 has a first mounting portion 110 and a second mounting portion 120 spaced apart on one side; the support body 200 has a first mounting groove 210 and a second mounting groove 220 spaced apart on the side near the fixed body 100. The first mounting portion 110 is fitted with the inner wall of the first mounting groove 210, and the second mounting portion 120 is fitted with the inner wall of the second mounting groove 220, causing the fixed body 100 to be inclined relative to the support body 200; the first locking member is used to lock the fixed body 100 and the support body 200 together.

[0029] In the vibration fixture 10 described above, the support body 200 is fixed to a single-axis excitation vibration table, allowing the table to apply vibration excitation along the normal direction of the side of the support body 200 closest to the fixed body 100. Simultaneously, the test sample is fixed to the side of the fixed body 100 away from the support body 200. Because the fixed body 100 is inclined relative to the support body 200, when the single-axis excitation vibration table applies vibration excitation to the support body 200, the test sample on the fixed body 100 can generate vibration responses in three different directions, achieving the required vibration magnitudes in three different directions. Compared to current vibration fixtures, this application, by fixing the test sample to the fixed body 100 inclined relative to the support body 200, achieves simultaneous vibration response in three directions with a single fixation and vibration excitation applied in one direction. This reduces the need for direction changes and adjustments of the vibration fixture 10, reduces the time required for direction changes, shortens the vibration test cycle, improves the efficiency of the vibration test, and also reduces the risk of damage and failure of the test sample.

[0030] The fixed body 100 can be a fixed plate, a fixed frame, or other fixed structure. The supporting body 200 can be a supporting plate, a supporting base, or other supporting structure. Specifically, in this embodiment, the supporting body 200 is set as a supporting plate, and the fixed body 100 is set as a fixed plate. Both the supporting plate and the fixed plate are made of aluminum alloy.

[0031] The fixed body 100 is inclined relative to the support body 200, which can be achieved by at least one of the following design methods: different dimensions of the first mounting part 110 and the second mounting part 120; different heights of the first mounting part 110 relative to the fixed body 100 and the second mounting part 120 relative to the fixed body 100; different dimensions of the first mounting groove 210 and the second mounting groove 220; and different heights of the side of the first mounting groove 210 away from the fixed body 100 relative to the support body 200 and the side of the second mounting groove 220 away from the fixed body 100 relative to the support body 200. Specifically, in this embodiment, the inclined setting of the fixed body 100 relative to the support body 200 means that the side of the fixed body 100 used to mount the test sample (i.e., the side of the fixed body 100 away from the support body 200) is inclined relative to the side of the support body 200 used to fit against the uniaxial excitation vibration table (i.e., the side of the support body 200 away from the fixed body 100).

[0032] like Figure 2 and Figure 3As shown, further, the distance between the first mounting groove 210 and the side of the support body 200 away from the fixed body 100 is the first height, and the distance between the second mounting groove 220 and the side of the support body 200 away from the fixed body 100 is the second height. The second height is greater than the first height. Both the first mounting groove 210 and the second mounting groove 220 penetrate the support body 200. The two inner sidewalls of the first mounting groove 210 and the two inner sidewalls of the second mounting groove 220 are set at an angle. The first mounting part 110 includes a first outer cylindrical surface 111, which is matched with the inner sidewall of the first mounting groove 210. The second mounting part 120 includes a second outer cylindrical surface 121, which is matched with the inner sidewall of the second mounting groove 220. Thus, by limiting the fit between the first outer cylindrical surface 111 and the inner wall of the first mounting groove 210, and limiting the fit between the second outer cylindrical surface 121 and the inner wall of the second mounting groove 220, on the one hand, the positioning accuracy and centering of the test sample are improved, and the positional deviation of the test sample is reduced; on the other hand, the types and specifications of vibration fixtures 10 can be greatly reduced, the versatility of vibration fixtures 10 is improved, and the fixture management and manufacturing costs of vibration-related tests are also greatly reduced.

[0033] The included angle between the two opposing inner walls of the first mounting groove 210 and the two opposing inner walls of the second mounting groove 220 can be flexibly adjusted according to actual usage needs. Specifically, in this embodiment, the two opposing inner walls of the first mounting groove 210 and the two opposing inner walls of the second mounting groove 220 are vertically arranged. This allows for vibration of test samples of various sizes in different directions without removing the test samples.

[0034] Specifically, in this embodiment, the first outer cylindrical surface 111 is tangent to the two inner sidewalls opposite to the first mounting groove 210, and the second outer cylindrical surface 121 is tangent to the two inner sidewalls opposite to the second mounting groove 220. For example... Figure 2 and Figure 3 As shown, optionally, the number of first mounting portions 110 is at least one, and each first mounting portion 110 is spaced apart along the extension direction of the first mounting groove 210; the number of second mounting portions 120 is at least one, and each second mounting portion 120 is spaced apart along the extension direction of the second mounting groove 220. Thus, by increasing the number of first mounting portions 110 and second mounting portions 120, the contact area between the support body 200 and the fixed body 100 is increased, ensuring that the vibration excitation on the uniaxial excitation vibration table can be transmitted to the test sample through the support body 200, the first mounting portions 110, the second mounting portions 120, and the fixed body 100, thereby improving the reliability of the vibration fixture 10.

[0035] The number of the first mounting portion 110 and the second mounting portion 120 can be flexibly adjusted according to the size of the test sample mounted on the fixed body 100. That is, the larger the size of the side of the fixed body 100 used to mount the test sample, the more first mounting portions 110 and second mounting portions 120 there are. Specifically, in this embodiment, there are two first mounting portions 110 and two mounting portions 120. In addition, in order to reduce weight, when there are at least two first mounting portions 110 and two mounting portions 120, they are spaced apart from each other.

[0036] like Figure 3 As shown, optionally, the first mounting portion 110 is provided with a first hollow hole 112, and the second mounting portion 120 is provided with a second hollow hole 122. Thus, both the first mounting portion 110 and the second mounting portion 120 are hollow structures, reducing the weight of the vibration clamp 10 and improving its convenience. Specifically, in this embodiment, the first mounting groove 210, the second mounting groove 220, the first hollow hole 112, and the second hollow hole 122 all extend in the same direction.

[0037] like Figure 1 As shown, in one embodiment, the vibration fixture 10 further includes an adjustment component 300, which is installed in the second mounting groove 220. The adjustment component 300 is in a limiting engagement with the second outer cylindrical surface 121 to adjust the tilt angle of the fixed body 100 relative to the support body 200. Thus, the adjustment component 300 can adjust the position of the second mounting part 120 relative to the second mounting groove 220, while the position of the first mounting part 110 relative to the first mounting groove 210 remains fixed. This makes the tilt angle of the fixed body 100 relative to the support body 200 adjustable, thereby meeting the vibration test requirements of different test samples and improving the practicality of the vibration fixture 10.

[0038] In other embodiments, the adjustment component 300 may also be correspondingly disposed at the first mounting groove 210, and the adjustment component 300 shall be limited and engaged with the first outer cylindrical surface 111 to adjust the tilt angle of the fixed body 100 relative to the supporting body 200. Alternatively, adjustment components 300 may be provided at both the first mounting groove 210 and the second mounting groove 220, and the two adjustment components 300 shall be correspondingly limited and engaged with the first outer cylindrical surface 111 and the second outer cylindrical surface 121 respectively to adjust the tilt angle of the fixed body 100 relative to the supporting body 200.

[0039] like Figure 1As shown, the adjustment assembly 300 further includes a shim 310, a crimping member 320, and a second locking member (not shown). The shim 310 is disposed on the bottom wall of the second mounting groove 220. The crimping member 320 passes through the second mounting groove 220 and abuts against the shim 310. The second locking member is used to lock the crimping member 320 to the support body 200. In this way, by changing the number or size of the shims 310, the tilt angle of the fixed body 100 relative to the support body 200 can be adjusted, thereby meeting the vibration test requirements of different test samples, improving the flexibility and versatility of the vibration fixture 10, and reducing the variety of specifications of the vibration fixture 10, thereby reducing manufacturing and management costs.

[0040] Specifically, in this embodiment, the two inner sidewalls opposite to the first outer cylindrical surface 111 and the first mounting groove 210 are both in a limiting fit, and the second outer cylindrical surface 121 is in a limiting fit with the crimping member 130 and the inner sidewall of the second mounting groove 220 on the side close to the first mounting groove 210.

[0041] The shim 310 can be a shim, strip, or other shim structure. The crimping member 320 can be a pressure plate, strip, or other crimping structure. Both the first and second locking members can be pins, bolts, clamps, or other locking structures.

[0042] like Figure 1 As shown, optionally, both ends of the crimping member 320 are provided with flange portions 321, and the flange portions 321 are provided with first fixing grooves 330. The support body 200 is provided with second fixing grooves 230, which penetrate through the support body 200. The two ends of the second fixing groove 230 are respectively connected to the two first fixing grooves 330. The second locking member is provided as a second bolt, which passes through the second fixing groove 230 and the two first fixing grooves 330 to lock the two flange portions 321 to the support body 200. The shim 310 is provided as a shim strip, and the crimping member 320 is provided as a pressure plate. In this way, the structure of the support plate, fixing plate, shim strip, and pressure plate is simple, easy to manufacture, and easy to install and disassemble. In addition, the vibration fixture 10 in this embodiment is highly practical and technically advanced. It can be widely used in one-dimensional single-axis vibration tables to carry out vibration tests. From design to manufacturing, everything can be realized. It can be used as a general-purpose tooling fixture for vibration testing of test samples.

[0043] Specifically, in this embodiment, the first fixing groove 330 is configured as a first elongated oval groove, and the second fixing groove 230 is configured as a second elongated oval groove. Both the first and second elongated oval grooves extend along the depth direction of the second mounting groove 220. The pad and the pressure plate are both made of aluminum alloy. This reduces the weight of the vibration fixture 10 and ensures that the specific stiffness of the vibration fixture 10 meets the test requirements.

[0044] Optionally, the support body 200 is provided with two extensions 130 extending towards the side closest to the fixed body 100. Each extension 130 has a third fixing groove 140. The support body 200 has a fourth fixing groove 240 that penetrates the support body 200. Both ends of the fourth fixing groove 240 are respectively connected to the two third fixing grooves 140. A first locking element is provided as a first bolt, which passes through the fourth fixing groove 240 and the two third fixing grooves 140 to lock the two extensions 130 into the support body 200. This improves the ease of assembly of the vibration clamp 10.

[0045] Specifically, in this embodiment, the third fixing groove 140 is configured as a third elongated oval groove, and the fourth fixing groove 240 is configured as a fourth elongated oval groove. Both the third and fourth elongated oval grooves extend along the width direction of the second mounting groove 220. Thus, when the tilt angle of the fixing body 100 relative to the supporting body 200 is adjusted to any angle value, the first bolt can pass through the fourth elongated oval groove and the two third elongated oval grooves to lock the two extensions 130 into the supporting body 200, thereby improving the reliability of the vibration clamp 10.

[0046] In one embodiment, a vibration testing device is provided, including a uniaxial excitation vibration table and a vibration clamp 10 as described in any of the above embodiments, wherein the vibration clamp 10 is fixed to the uniaxial excitation vibration table.

[0047] In the vibration testing equipment described in the above embodiments, the support body 200 is fixed on a uniaxial excitation vibration table, allowing the uniaxial excitation vibration table to apply vibration excitation to the support body 200 along the normal direction of the side of the support body 200 closest to the fixed body 100. Simultaneously, the test sample is fixed on the side of the fixed body 100 away from the support body 200. Because the fixed body 100 is inclined relative to the support body 200, when the uniaxial excitation vibration table applies a vibration excitation to the support body 200, the test sample on the fixed body 100 can generate vibration responses in three different directions, achieving the required vibration magnitudes in three different directions. Compared to the current vibration fixture 10, this application, by fixing the test sample to the fixed body 100 inclined relative to the support body 200, achieves one-time fixing, one-direction vibration excitation, and simultaneous vibration responses in three directions. This reduces the need for direction changes and adjustments with the vibration fixture 10, reduces the time required for direction changes, shortens the vibration testing cycle, improves the efficiency of the vibration testing, and also reduces the risk of damage and failure of the test sample.
