[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Embodiment 1

[0024] In the prior art, the shear tester can only test a single device. This means that when multiple different types of devices need to be tested, the operator must first remove the device in the fixture before replacing it with another device for testing. As a result, the tester must be shut down when replacing the device, causing the test work to be interrupted. Therefore, this operation method leads to low work efficiency.

[0025] Therefore, in order to solve the problem that the existing tester can only test a single device, and when multiple devices need to be tested, the device can only be taken out frequently, and the test work will be interrupted when the device is replaced, resulting in reduced work efficiency, and realize the function of saving the taking steps and improving the test efficiency, the utility model discloses a welding strength and shear strength tester, referring to Figure 1-Figure 2 , comprising a test platform 1 and a measuring module 2 fixed in parallel to the top of the test platform 1, a driving member is arranged inside the test platform 1, and a disc-shaped base 3 is arranged on the side of the test platform 1 facing the measuring module 2, and a rotating shaft 7 is arranged at the bottom of the base 3, and the rotating shaft 7 is connected to the driving member, and a plurality of cylindrical mounting seats 4 distributed along the edge of the base 3 are arranged on the top of the base 3, and a fixing fixture 5 is penetrated inside the mounting seat 4;

[0026] In this embodiment, the driving member can select a driving motor, which drives the rotating shaft 7 through the driving motor, so that the base 3 can make a circular rotation with the fixed fixture 5 on the mounting seat 4. Through the above structure, the operator can place several devices to be tested in several fixed fixtures 5 respectively. Then, when the test of the device in one of the fixed fixtures 5 is completed, the driving member is turned on to rotate the base 3, so as to move the next device to be tested to the bottom of the measuring module 2. At the same time, the operator can take out the tested device and replace it with another device to be tested, so that the tester can replace the test device without stopping, thereby improving the test efficiency.

[0027] In this embodiment, in order to further improve the installation efficiency of the device, an opening is provided at the top of the mounting seat 4, and a connecting column 12 corresponding to the opening is provided on the side of the fixing fixture 5 facing the mounting seat 4. The operator can pre-fix the device on the fixing fixture 5 that is not connected to the mounting seat 4. Then, when the base 3 rotates the tested device out from under the measuring module 2, the operator can directly remove the device together with the fixing fixture 5 from under the mounting seat 4, and then insert the fixing fixture 5 with the device to be tested into the mounting seat 3.

[0028] In the above embodiment, the connecting column 12 is cylindrical, the opening of the mounting seat 4 is circular, and corresponding threads are provided on the surface of the connecting column 12 and the inner wall of the opening, but the present invention is not limited thereto.

[0029] In this embodiment, the measuring module 2 includes a hydraulic cylinder, a lifting rod and a pressure sensor, wherein the lifting rod and the hydraulic cylinder are interconnected, and the pressure sensor and the hydraulic cylinder are interconnected. The measuring module 2 is provided with a push knife 6 on the side facing the base 3, and the push knife 6 is distributed in parallel above any mounting seat 4 fixed on the top of the base 3, and the push knife 6 is connected to the lifting rod. Through the above structure, the push knife 6 can be pressed down from the measuring module 2 to the corresponding fixed fixture 5, so as to apply shear force to the device in the fixed fixture 5, and then the pressure sensor can determine the shear force currently borne by the device by sensing the pressure of the hydraulic cylinder.

[0030] In the above embodiment, a wireless communication module is provided inside the measuring module 2, and the pressure sensor is connected to the external display device through the wireless communication module.

[0031] Working principle: through the setting of the rotating shaft 7 and multiple mounting seats 4, the base 3 can be driven by the rotating shaft 7 to move the fixing fixtures 5 fixed on the multiple mounting seats 4 on the top of the base 3 to the bottom of the push knife 6 in sequence, so that the push knife 6 can cut multiple devices in sequence. Secondly, the operator can replace the cut device or the fixing fixture 5 while the push knife 6 is cutting, so that the device can be replaced without stopping the tester, thereby improving the detection efficiency of the tester.

[0032] During use: the operator can put several devices to be tested into the clamping grooves of the corresponding fixed fixture 5 in turn, and then start the driving part so that the rotating shaft 7 can rotate the base 3, so as to rotate any fixed fixture 5 to the bottom of the push knife 6, and then start the hydraulic cylinder so that the lifting rod can press the push knife 6 down to the fixed fixture 5 and contact the device to be tested. With the continuous pressure of the hydraulic cylinder, the push knife 6 can shear the device. At the same time, the pressure sensor can feed back the pressure value applied by the hydraulic cylinder to the external display, so as to achieve the purpose of testing the shear resistance of the device. Then, when the test is completed, the driving part is turned on again, so that the base 3 can rotate the next fixed fixture 5 to the bottom of the push knife 6, and then repeat the above operation. In this process, the operator can take out the connecting column 12 from the inside of the mounting seat 4 to directly replace the fixed fixture 5 and the device.

[0033] Embodiment 2

[0034] In order to prevent the device fixed in the fixing fixture 5 from loosening, avoid the problem of position deviation during the shearing process, and improve the fixing effect of the device, refer to Figure 3-Figure 4 On the basis of the first embodiment, it further includes a clamping plate 8, through which the device is clamped in the fixing fixture 5. Specifically, threaded holes are provided on any two parallel inner walls of the clamping groove, and a screw 10 is movably passed through the inside of the threaded hole, wherein one side of the screw 10 located inside the clamping groove is movably connected to the clamping plate 8, and the other side of the screw 10 is fixedly connected to the rotating rod 9.

[0035] In this embodiment, after the operator places the device into the clamping groove, the rotating rods 9 on both sides of the fixing fixture 5 can be rotated at the same time so that the screw 10 can push the clamping plate 8 toward the device, thereby achieving the effect of tightening the device and further improving the fixing effect of the device.

[0036] In the above embodiment, by providing the screw rod 10 and the rotating rod 9 , the clamping plate 8 can clamp components of different sizes, further improving the versatility of the fixing fixture 5 .

[0037] In the above embodiment, preferably, a clamping groove is provided on the side of the fixing fixture 5 facing the measuring module 2, and a plurality of strip-shaped supporting protrusions 11 are provided at the bottom of the clamping groove. The supporting protrusions 11 can increase the friction between the device and the inside of the clamping groove, further avoiding the device from sliding during the shearing process.

[0038] In this embodiment, a sleeve rod 13 is provided on the side of the clamping plate 8 facing the screw rod 10, and the screw rod 10 is movably inserted into the sleeve rod 13 and fits with the clamping plate 8. Through the above structure, when the screw rod 10 moves toward the device, it will continuously push the clamping plate 8, so that the clamping plate 8 can be smoothly and tightly attached to the side of the device.

[0039] In this embodiment, a traction block 14 is provided at one end of the screw rod 10 that passes through the sleeve rod 13, and the traction block 14 is longer than the inner diameter of the through hole where the sleeve rod 13 and the screw rod 10 are inserted. Through the above structure, when the device needs to be removed, the screw rod 10 can be moved in the opposite direction of the device, and then the traction block 14 will be blocked in the through hole of the sleeve rod 13, so as to pull the clamping plate 8 back to its original position.

[0040] Working principle: through the setting of the clamping plate 8, the screw 10 and the rotating rod 9, the rotating rod 9 can drive the screw 10 to rotate in the screw hole on the inner wall of the clamping groove, so that the screw 10 can push the clamping plate 8 toward the device or detach from the device, so that the device can be fixedly clamped in the fixing fixture 5. Secondly, through the setting of the supporting protrusion 11, the friction between the device and the fixing fixture 5 is increased, which further avoids the sliding of the device and improves the test accuracy.

[0041] During use: In the initial state, the clamping plate 8 is movably fitted on the inner wall of the clamping groove. Then, when the device is placed in the clamping groove, the operator can simultaneously rotate the rotating rods 9 on both sides of the fixing fixture 5, so that the screw 10 can drive the clamping plate 8 to move and fit to both sides of the device, and then stop rotating the rotating rod 8 so that the screw 10 can be fixed in the current position, thereby clamping the device in the fixing fixture 5.

[0042] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
