[0026] Example 1

[0027] Reference Figure 1-4The first embodiment of this utility model provides an automatic pendulum impact testing machine. The test component 1 includes an impact testing machine 101 and a mounting base 102. The lower end of the impact testing machine 101 is fixedly connected to the upper end of the mounting base 102. An adjustment mechanism 2 is provided on the impact testing machine 101, and a limit mechanism 4 is provided on the mounting base 102. The test component 1 is used to perform impact testing operations, the adjustment mechanism 2 is used to adjust the impact force of the test, and the limit mechanism 4 is used to fix the test object.

[0028] Specifically, by setting an adjustment mechanism 2 on the impact testing machine 101 and a limiting mechanism 4 on the mounting base 102, the problems of inconvenient operation and poor adaptability of existing impact testing equipment when adjusting the impact force and fixing the test object are solved. This structure can flexibly adjust the position of the hammer head 203 to adjust the impact force according to different test requirements. At the same time, the limiting mechanism 4 stably clamps the test objects of different sizes to prevent impact errors caused by object displacement during the test, thereby improving the test accuracy and the applicability of the equipment.

[0029] Furthermore, the impact testing machine 101 is used to test the object to be tested, and the impact force of the test is adjusted by the adjustment mechanism 2. The limiting mechanism 4 is used to limit different test objects.

[0030] Example 2

[0031] The second embodiment of this utility model provides an automatic pendulum impact testing machine 101. The adjusting mechanism 2 includes a mounting block 201, a swing arm 202, a hammer head 203, limiting holes 204, and a fixing pin 205. The inner wall of the mounting block 201 is slidably connected to the surface of the swing arm 202, and the upper end of the swing arm 202 is fixedly connected to the inner wall of the hammer head 203. A plurality of limiting holes 204 are provided on the surface of the swing arm 202, and the inner wall of the limiting holes 204 contacts the surface of the fixing pin 205. An auxiliary mechanism 3 is provided on the adjusting mechanism 2, and the auxiliary mechanism 3 includes a mating pin 3. 01. Elastic block 302 and fixing hole 303, the surface of mating pin 301 is fixedly connected to the rear end of elastic block 302, fixing hole 303 is opened on the surface of fixing pin 205, the surface of mounting block 201 is rotatably connected to the surface of impact testing machine 101, the inner wall of mounting block 201 is slidably connected to the surface of fixing pin 205 through a sliding groove, the surface of mating pin 301 is slidably connected to the inner wall of mounting block 201 through a sliding groove, the front end surface of elastic block 302 is fixedly connected to the surface of mounting block 201, and the surface of mating pin 301 is in contact with the inner wall of fixing hole 303.

[0032] Specifically, by setting up an adjustment mechanism 2 consisting of a mounting block 201, a swing arm 202, a hammer head 203, a limiting hole 204, a fixing pin 205, and an auxiliary mechanism 3, the problems of complex operation, inaccurate positioning, and easy loosening when adjusting the height of the hammer head 203 in traditional impact testing equipment are solved. This structure achieves flexible adjustment of the position of the hammer head 203 through a sliding connection, and uses the fixing pin 205 and the limiting hole 204 to achieve initial positioning. Then, the mating pin 301 is inserted into the fixing hole 303 of the fixing pin 205 to complete the secondary locking, thereby effectively improving the adjustment accuracy and structural stability, avoiding impact deviation caused by loose parts during the test, and improving the reliability of the test results and operational safety.

[0033] Furthermore, firstly, the object to be tested is placed on the upper end of the mounting base 102, and the positions of the swing arm 202 and the hammer head 203 are adjusted. To achieve this adjustment, the mating pin 301 inside the mounting block 201 is first pulled out from the fixing hole 303 on the fixing pin 205, and then the fixing pin 205 is pulled out from the limiting hole 204 on the swing arm 202. At this time, the swing arm 202 can slide in the inner wall of the mounting block 201, while driving the hammer head 203 fixed at its upper end to move together. When the hammer head 203 is adjusted to the appropriate position, the test is repeated. Insert the fixing pin 205 into the corresponding limiting hole 204 to ensure the stability of the swing arm 202. After the initial fixing of the hammer head 203 is completed, in order to further enhance the stability of the structure, the mating pin 301 needs to be inserted again into the fixing hole 303 in the fixing pin 205 to lock the position of the fixing pin 205, thereby further stabilizing the overall structure of the swing arm 202 and the hammer head 203. This step can effectively prevent the impact position shift or test error caused by loose parts in the subsequent test process, and ensure the safety and accuracy of the entire adjustment process.

[0034] Example 3

[0035] The second embodiment of this utility model provides an automatic pendulum impact testing machine 101. The limiting mechanism 4 includes a servo motor 401, a drive screw 402, a mating screw sleeve 403, an anti-slip plate 404, a support plate 405, and a protective plate 406. The output end of the servo motor 401 is fixedly connected to the upper end of the drive screw 402. The surface of the drive screw 402 is threadedly connected to the inner wall of the mating screw sleeve 403. The surface of the mating screw sleeve 403 is fixedly connected to the surface of the anti-slip plate 404. The lower end of the drive screw 402 is rotatably connected to the inner wall of the support plate 405. The left side of the mounting base 102 is fixedly connected to the lower end of the protective plate 406. The surface of the servo motor 401 is fixedly connected to the upper end of the support plate 405. The surface of the anti-slip plate 404 is slidably connected to the inner wall of the impact testing machine 101 through a sliding groove. The lower end of the mounting base 102 is fixedly connected to the surface of the support plate 405.

[0036] Specifically, the automatic pendulum impact testing machine 101 provided by this utility model solves the problem of the impact point shifting due to insecure fixing of the object under test during the impact test by setting a limiting mechanism 4 composed of a servo motor 401, an active screw 402, a matching screw sleeve 403, and an anti-slip plate 404.

[0037] Furthermore, after the hammer head 203 and swing arm 202 system are adjusted, the next step is to fix the object to be tested. The servo motor 401 on the mounting base 102 is started, and the active screw 402 is driven to rotate through its output end. The mating screw sleeve 403 on the surface of the active screw 402 moves downward under the action of thread transmission, driving the anti-slip plate 404 to descend synchronously until it contacts the upper surface of the object and applies appropriate pressure, thereby achieving reliable clamping of the object to be tested. This can effectively avoid the impact point deviation caused by the displacement of the object during the test. After clamping is completed, the impact test operation can begin.

[0038] Working principle:

[0039] Before conducting the impact test, the equipment needs to be adjusted according to the size of the object to be tested and the test requirements. First, place the object to be tested on the upper end of the mounting base 102 and adjust the positions of the swing arm 202 and the hammer 203. To achieve this adjustment, first pull the mating pin 301 inside the mounting block 201 out of the fixing hole 303 on the fixing pin 205, and then pull the fixing pin 205 out of the limiting hole 204 on the swing arm 202. At this time, the swing arm 202 can slide in the inner wall of the mounting block 201, and at the same time drive the hammer 203 fixed at its upper end to move together. After the hammer 203 is adjusted to the appropriate position, re-insert the fixing pin 205 into the corresponding limiting hole 204 to ensure the stability of the swing arm 202. After completing the initial fixation of the hammer 203 position, in order to further enhance the stability of the structure, the mating pin 301 needs to be reinserted into the fixing pin 205. The fixing pin 205 is locked in the fixing hole 303 to further stabilize the overall structure of the swing arm 202 and the hammer head 203. This step can effectively prevent the impact position displacement or test error caused by the loosening of parts during subsequent tests, and ensure the safety and accuracy of the entire adjustment process. After the hammer head 203 and the swing arm 202 system are adjusted, the next step is to fix the object to be tested. The servo motor 401 on the mounting base 102 is started, and the active screw 402 is driven to rotate through its output end. The mating screw sleeve 403 on the surface of the active screw 402 moves downward under the action of thread transmission, driving the anti-slip plate 404 to descend synchronously until it contacts the upper surface of the object and applies appropriate pressure, thereby achieving reliable clamping of the object to be tested. This can effectively avoid the impact point deviation caused by the displacement of the object during the test. After clamping is completed, the impact test operation can be started.

[0040] In summary, by using the cooperation of the locking pin and the fixing pin, and the synergistic effect of the servo motor driving the active screw and the anti-slip plate, the precise adjustment of the hammer position and the stable fixation of the test object are achieved, thereby effectively ensuring the accuracy of the impact position and the reliability of the test results during the impact test.
