In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0028] The present invention provides an impact device, such as Figure 1 As shown, the impact device includes a frame 12, a table assembly 2, a waveform generator, a propulsion mechanism and a sensor (not shown in the figure). Among them, the waveform generator includes an X-direction waveform generator 31, a Y-direction waveform generator 32, and a Z-direction waveform generator 33. The propulsion mechanism includes an X-direction propulsion mechanism 41, a Y-direction propulsion mechanism 42, and a Z-direction propulsion mechanism 43. Specifically, the table assembly 2 is installed on the frame 12, and the table assembly 2 can selectively slide relative to the frame 12 along any direction of the X-direction, the Y-direction, and the Z-direction, and the X-direction, the Y-direction, and the Z-direction are perpendicular to each other, and the table assembly 2 can carry the test piece. The X-direction waveform generator 31 is arranged relative to the table assembly 2 along the X-direction, the Y-direction waveform generator 32 is arranged relative to the table assembly 2 along the Y-direction, and the Z-direction waveform generator 33 is arranged relative to the table assembly 2 along the Z-direction.

[0029] The X-direction propulsion mechanism 41 is arranged relative to the table assembly 2 along the X-direction and is located on the side of the table assembly 2 away from the X-direction waveform generator 31. The X-direction propulsion mechanism 41 can drive the table assembly 2 to move along the X-direction so that the table assembly 2 impacts the X-direction waveform generator 31 along the X-direction. The Y-direction propulsion mechanism 42 is arranged relative to the table assembly 2 along the Y-direction and is located on the side of the table assembly 2 away from the Y-direction waveform generator 32. The Y-direction propulsion mechanism 42 can drive the table assembly 2 to move along the Y-direction so that the table assembly 2 impacts the Y-direction waveform generator 32 along the Y-direction. The Z-direction propulsion mechanism 43 is arranged relative to the table assembly 2 along the Z-direction. The Z-direction propulsion mechanism 43 can drive at least part of the table assembly 2 to move along the Z-direction, and at least part of the table assembly 2 can impact the Z-direction waveform generator 33 along the Z-direction. The sensor is installed on the table assembly 2 for collecting and processing the impact test results.

[0030] The specific working process of the impact equipment is roughly as follows: the workpiece to be tested is placed on the table assembly 2; when it is necessary to test the impact performance of the workpiece to be tested along the X-direction, the table assembly 2 can only move along the X-direction relative to the frame 12, at this time the X-direction propulsion mechanism 41 impacts the table assembly 2, and the table assembly 2 hits the corresponding X-direction waveform generator 31 along the X-direction, thereby generating the half-sine impact pulse required for the test, and the sensor detects the half-sine impact pulse to facilitate the evaluation of the impact result, thereby realizing the test of the impact resistance of the workpiece to be tested along the X-direction.

[0031] When it is necessary to test the impact performance of the test piece along the Y direction, the table assembly 2 can only move along the Y direction relative to the frame 12. At this time, the Y-direction propulsion mechanism 42 impacts the table assembly 2, and the table assembly 2 hits the corresponding Y-direction waveform generator 32 along the Y direction, thereby generating the half-sine impact pulse required for the test. The sensor detects the half-sine impact pulse to evaluate the impact result, thereby realizing the test of the impact resistance of the test piece along the Y direction.

[0032] When it is necessary to test the impact performance of the test piece along the Z direction, at least part of the table assembly 2 can only move along the Z direction relative to the frame 12. After the Z-direction propulsion mechanism 43 lifts at least part of the table assembly 2 to reach the specified height, at least part of the table assembly 2 moves downward under the action of gravity and hits the corresponding Z-direction waveform generator 33 along the Z direction, thereby generating the half-sine shock pulse required for the test. The sensor detects the half-sine shock pulse to facilitate the evaluation of the impact result, thereby realizing the test of the impact resistance of the test piece along the Z direction.

[0033] The impact device of the present invention can realize the impact test of the workpiece to be tested along the X direction, Y direction and Z direction without turning over the impact device or clamping the workpiece to be tested multiple times. It is not only easy to operate, but also saves manpower and material resources, and avoids damage to the workpiece to be tested during the turning process.

[0034] In this embodiment, Figure 1 As shown, the frame 12 includes a base plate 121 and a plurality of pillars 122, and the plurality of pillars 122 are evenly installed on the base plate 121 for supporting the table assembly 2. The arrangement of the pillars 122 forms a certain space between the base plate 121 and the table assembly 2, so as to facilitate the installation of other parts of the impact device. Optionally, the base plate 121 is in a rectangular, circular or polygonal shape, etc., which is not limited here. Optionally, the number of pillars 122 can be four, six, eight, etc., which is not specifically limited here. In this embodiment, the base plate 121 is a rectangular parallelepiped, and the number of pillars 122 is four.

[0035] In this embodiment, the table assembly 2 includes a workbench 21 and a support plate 22, the support plate 22 is used to connect to the frame 12, the workbench 21 is installed on the support plate 22, and is used to carry the test piece. Optionally, the workbench 21 is welded and formed with high-quality structural steel to ensure the structural strength of the workbench 21 and avoid damage to the workbench 21 during impact. The interior of the workbench 21 is welded in a grid shape, which can reduce the overall weight and ensure sufficient bearing capacity. In this embodiment, the sensor is arranged on the workbench 21.

[0036] In this embodiment, the impact device further includes a measurement and control component (not shown in the figure), which includes a computer, and the computer is used for the operator to operate and analyze the experimental results. Specifically, the measurement and control component is electrically connected to the sensor. When the workbench 21 impacts the X-direction waveform generator 31 along the X direction (or impacts the Y-direction waveform generator 32 along the Y direction, or impacts the Z-direction waveform generator 33 along the Z direction) and generates the half-sine impact pulse required for the impact test, the sensor collects the acceleration, impact time, impact force and other information of the impact, and outputs it to the measurement and control component, which processes and analyzes the collected results and evaluates the impact performance of the test piece.

[0037] like Figure 2 As shown, in this embodiment, the workbench 21 includes a workbench body 211, and the workpiece to be tested is fixed on the workbench body 211. The workbench 21 also includes a first elastic member, and the first elastic member includes an X-direction first elastic member 212 and a Y-direction first elastic member 213.

[0038] The first X-direction elastic member 212 is arranged on one side of the workbench body 211 along the X-direction and is arranged opposite to the X-direction propulsion mechanism 41. When the X-direction impact test is performed on the test piece, the X-direction propulsion mechanism 41 first impacts the first X-direction elastic member 212 to make the table assembly 2 move along the X-direction, and then the table assembly 2 impacts the X-direction waveform generator 31 along the X-direction, thereby generating the half-sine impact pulse required for the test. The first X-direction elastic member 212 is used to change the initial acceleration and pulse width generated by the X-direction propulsion mechanism 41 impacting the table assembly 2. Optionally, the first X-direction elastic member 212 can be a rubber pad. Changing the material or thickness of the rubber pad can change the initial acceleration and pulse width generated by the X-direction propulsion mechanism 41 impacting the table assembly 2. In this embodiment, one X-direction propulsion mechanism 41 is provided, and correspondingly, one X-direction first elastic member 212 is provided.

[0039] The first Y-direction elastic member 213 is arranged on one side of the workbench body 211 along the Y-direction and is arranged opposite to the Y-direction propulsion mechanism 42. When the workpiece to be tested is subjected to a Y-direction impact test, the Y-direction propulsion mechanism 42 first impacts the first Y-direction elastic member 213 to make the table assembly 2 move along the Y-direction, and then the table assembly 2 impacts the Y-direction waveform generator 32 along the Y-direction, thereby generating a half-sine pulse required for the test. The first Y-direction elastic member 213 is used to change the initial acceleration and pulse width generated by the Y-direction propulsion mechanism 42 impacting the table assembly 2. Optionally, the first Y-direction elastic member 213 can be a rubber pad. Changing the material or thickness of the rubber pad can change the initial acceleration and pulse width generated by the Y-direction propulsion mechanism 42 impacting the table assembly 2. In this embodiment, one Y-direction propulsion mechanism 42 is provided, and correspondingly, one Y-direction first elastic member 213 is provided.

[0040] In this embodiment, the X-direction waveform generator 31 and the Y-direction waveform generator 32 both include a second elastic member. In this embodiment, the second elastic member is a rubber pad. In some embodiments, the second elastic member is a diaphragm or a spring, etc., and the table assembly 2 can obtain the required half-sine pulse after impacting the second elastic member, which is not specifically limited here. It is understandable that the half-sine pulse generated by the impact test can be adjusted by changing the thickness and stiffness of the second elastic member.

[0041] Specifically, Figure 2As shown, the X-direction waveform generator 31 includes an X-direction second elastic member 311, which is arranged relative to the table assembly 2 along the X direction to ensure that the table assembly 2 can generate the half-sine pulse required for the test after colliding with the X-direction waveform generator 31. In this embodiment, two X-direction second elastic members 311 are provided. In other embodiments, one, three, four or more X-direction second elastic members 311 can be provided, which is not specifically limited here, and the half-sine pulse of the impact test can be obtained. The Y-direction waveform generator 32 includes a Y-direction second elastic member 321, which is arranged relative to the table assembly 2 along the Y direction to ensure that the table assembly 2 can generate the half-sine pulse required for the test after colliding with the Y-direction waveform generator 32. In this embodiment, one Y-direction second elastic member 321 is provided, and in other embodiments, two, three, four or more Y-direction second elastic members 321 can be provided, which is not specifically limited here, and the half-sine pulse of the impact test can be obtained.

[0042] like Figure 2 As shown, in order to ensure that the workbench 21 accurately collides along the X-direction, the workbench 21 also includes an X-direction response head 214, which is arranged on the side of the workbench body 211 facing the X-direction waveform generator 31, and a slot is arranged on the end surface of the X-direction response head 214 facing the X-direction waveform generator 31. The X-direction waveform generator 31 also includes an X-direction correction member 312, which is plugged into the X-direction second elastic member 311, and the end of the X-direction correction member 312 protrudes from the end surface of the X-direction second elastic member 311 toward the workbench 21. In the process of the workbench 21 colliding with the X-direction waveform generator 31 along the X-direction, the X-direction correction member 312 is first inserted into the slot of the X-direction response head 214, thereby guiding the collision direction of the workbench 21, and then the X-direction response head 214 collides with the X-direction second elastic member 311, ensuring the accuracy of the collision direction, thereby ensuring the reliability of the test results. In this embodiment, the number of the X-direction response heads 214 is consistent with the number of the X-direction waveform generators 31 and corresponds one to one.

[0043] In order to ensure that the workbench 21 accurately collides along the Y direction, the workbench 21 further includes a Y-direction response head 215, which is arranged on the side of the workbench body 211 facing the Y-direction waveform generator 32, and a slot is arranged on the end surface of the Y-direction response head 215 facing the Y-direction waveform generator 32. The Y-direction waveform generator 32 further includes a Y-direction correction member 322, which is plugged into the Y-direction second elastic member 321, and the end of the Y-direction correction member 322 protrudes from the end surface of the Y-direction second elastic member 321 toward the workbench 21. In the process of the workbench 21 colliding with the Y-direction waveform generator 32 along the Y direction, the Y-direction correction member 322 is first inserted into the slot of the Y-direction response head 215, thereby guiding the collision direction of the workbench 21, and then the Y-direction response head 215 collides with the Y-direction second elastic member 321, ensuring the accuracy of the collision direction, thereby ensuring the reliability of the test results. In this embodiment, the number of the Y-direction response heads 215 is consistent with the number of the Y-direction waveform generators 32 and corresponds one to one.

[0044] like Figure 3 As shown, in order to prevent the table assembly 2 from being disturbed in the Y direction during the X-direction impact test, and to prevent the table assembly 2 from being disturbed in the X direction during the Y-direction impact test, the impact device further includes an X-direction guide assembly 51 and a Y-direction guide assembly 52. ​​The X-direction guide assembly 51 is mounted on the frame 12, the Y-direction guide assembly 52 is connected to the X-direction guide assembly 51, and can slide along the X-direction guide assembly 51 or lock with the X-direction guide assembly 51, and the table assembly 2 is connected to the Y-direction guide assembly 52, and can slide along the Y-direction guide assembly 52 or lock with the Y-direction guide assembly 52. ​​When the X-direction impact test is performed, the table assembly 2 is locked with the Y-direction guide assembly 52, and the Y-direction guide assembly 52 is unlocked with the X-direction guide assembly 51, so that the table assembly 2 can only slide along the X direction; when the Y-direction impact test is performed, the table assembly 2 is unlocked with the Y-direction guide assembly 52, and the X-direction guide assembly 51 is locked with the Y-direction guide assembly 52, so that the table assembly 2 can only slide along the Y direction.

[0045] In order to realize the connection between the X-direction guide assembly 51 and the Y-direction guide assembly 52, and the connection between the Y-direction guide assembly 52 and the table assembly 2, as shown in FIG. Figure 3 and Figure 4 As shown, the impact device further includes a first connecting component 511 and a second connecting component 521. The first connecting component 511 is sleeved on the X-direction guide component 51, and the Y-direction guide component 52 is connected to the first connecting component 511. The first connecting component 511 can slide along the X-direction guide component 51 or lock with the X-direction guide component 51. The second connecting component 521 is sleeved on the Y-direction guide component 52, and the table component 2 is connected to the second connecting component 521. The second connecting component 521 can slide along the Y-direction guide component 52 or lock with the Y-direction guide component 52.

[0046] like Figure 3As shown, in this embodiment, the X-direction guide assembly 51 is a guide rod, and is installed at the upper end of the pillar 122 of the frame 12 through a fixed seat 512. Optionally, two X-direction guide assemblies 51 are arranged in parallel, and four fixed seats 512 are arranged correspondingly at the four ends of the two X-direction guide assemblies 51, and the four fixed seats 512 are respectively fixedly connected to the four pillars 122. Two first connecting assemblies 511 are arranged on each X-direction guide assembly 51. The Y-direction guide assembly 52 is a guide rod, and two Y-direction guide assemblies 52 are arranged in parallel, and the two ends of each Y-direction guide assembly 52 are respectively fixedly connected to two first connecting assemblies 511 located on different X-direction guide assemblies 51 through guide sleeves 522. Two second connecting assemblies 521 are arranged on each Y-direction guide assembly 52, and the four second connecting assemblies 521 are all connected to the table assembly 2 to ensure that the table assembly 2 can slide smoothly along the Y direction. Optionally, the number of Y-direction guide assemblies 52 is not unique, and it is sufficient to achieve smooth sliding of the table assembly 2, and no specific limitation is made here.

[0047] like Figure 4 As shown, the first connecting assembly 511 includes a first guide sleeve 5111 and a first brake member 5112. The first guide sleeve 5111 is sleeved on the X-direction guide assembly 51 and fixedly connected to the Y-direction guide assembly 52. ​​The output end of the first brake member 5112 extends radially along the X-direction guide assembly 51 and can move relative to the first guide sleeve 5111. The first brake member 5112 is electrically connected to the measurement and control assembly, and the measurement and control assembly can control the output end of the first brake member 5112 to move radially along the first guide sleeve 5111. The second connecting assembly 521 includes a second guide sleeve 5211 and a second brake member 5212. The second guide sleeve 5211 is sleeved on the Y-direction guide assembly 52. ​​The output end of the second brake member 5212 extends radially along the Y-direction guide assembly 52 and can move relative to the second guide sleeve 5211. The second brake member 5212 is electrically connected to the measurement and control assembly, and the measurement and control assembly can control the output end of the second brake member 5212 to move radially along the second guide sleeve 5211.

[0048] When performing an X-direction impact test, the measurement and control component controls the output end of the second brake 5212 to move radially along the second guide sleeve 5211, and abuts to lock the Y-direction guide assembly 52, so that the second guide sleeve 5211 cannot slide on the Y-direction guide assembly 52, and only the first guide sleeve 5111 slides on the X-direction guide assembly 51, thereby allowing the table assembly 2 to move only along the X-direction.

[0049] When performing a Y-direction impact test, the measurement and control component controls the output end of the first brake 5112 to move radially along the first guide sleeve 5111, and abuts to lock the X-direction guide assembly 51, so that the first guide sleeve 5111 cannot slide on the X-direction guide assembly 51, and only the second guide sleeve 5211 slides on the Y-direction guide assembly 52, thereby allowing the table assembly 2 to move only along the Y-direction.

[0050] Optionally, the first brake member 5112 may be a cylinder, the cylinder body of which is connected to the first guide sleeve 5111, and the piston of which can abut against the X-direction guide assembly 51 to lock the X-direction guide assembly 51. The second brake member 5212 may also be a cylinder, the cylinder body of which is connected to the second guide sleeve 5211, and the piston of which can abut against the Y-direction guide assembly 52 to lock the Y-direction guide assembly 52.

[0051] like Figure 3 As shown, the upper surface of the second guide sleeve 5211 is the mounting surface, the support plate 22 is mounted on the mounting surface, and the workbench 21 is fixedly connected to the support plate 22 so that the table assembly 2 as a whole can slide or lock along the X-direction guide assembly 51 or the Y-direction guide assembly 52.

[0052] After the table assembly 2 collides with the X-direction waveform generator 31 or the Y-direction waveform generator 32, it will rebound, and then may collide with the propulsion mechanism, and after colliding with the propulsion mechanism, it will rebound and collide with the X-direction waveform generator 31 or the Y-direction waveform generator 32 again. In order to avoid this situation, when performing the X-direction impact test, after the table assembly 2 collides with the X-direction waveform generator 31 and rebounds, the output end of the first brake member 5112 can move in time along the radial direction of the first guide sleeve 5111 and abut against the X-direction guide assembly 51 to lock the X-direction guide assembly 51, thereby preventing the table assembly 2 from colliding with the X-direction propulsion mechanism 41 and a secondary collision with the X-direction waveform generator 31. When conducting the Y-direction impact test, after the table assembly 2 collides with the Y-direction waveform generator 32 and rebounds, the output end of the second brake member 5212 can promptly move radially along the second guide sleeve 5211 and abut against the Y-direction guide assembly 52 to lock the Y-direction guide assembly 52, thereby preventing the table assembly 2 from colliding with the Y-direction propulsion mechanism 42 and a secondary collision with the Y-direction waveform generator 32.

[0053] like Figure 1 and Figure 2 As shown, the impact device also includes an X-direction return component 44, which can restore the table assembly 2 to its initial position. Specifically, the initial position in the X-direction refers to the position of the table assembly 2 before being hit by the X-direction propulsion mechanism 41. At this position, a specified gap is left between the workbench 21 and the X-direction propulsion mechanism 41, and a specified gap is left between the workbench 21 and the X-direction waveform generator 31.

[0054] Furthermore, the impact device further includes an X-direction photoelectric sensor, and the X-direction return assembly 44 and the X-direction photoelectric sensor are both electrically connected to the measurement and control assembly, and the X-direction photoelectric sensor is used to detect the position of the workbench 21. By setting the X-direction photoelectric sensor, it is convenient for the measurement and control assembly to accurately know the position of the workbench 21, and then determine whether the workbench 21 is in the initial position, and the measurement and control assembly drives the X-direction return assembly 44 to act based on the judgment. Optionally, the position information of the workbench 21 can be displayed in real time on the computer, so that the operator can determine whether the table assembly 2 is returned to the position, and then proceed to the next step.

[0055] The impact device also includes a Y-direction return component 45, which can restore the table assembly 2 to its initial position. Specifically, the Y-direction initial position refers to the position of the table assembly 2 before being hit by the Y-direction propulsion mechanism 42. At this position, a specified gap is left between the workbench 21 and the Y-direction propulsion mechanism 42, and a specified gap is left between the workbench 21 and the Y-direction waveform generator 32.

[0056] Furthermore, the impact device further includes a Y-direction photoelectric sensor, and the Y-direction return assembly 45 and the Y-direction photoelectric sensor are both electrically connected to the measurement and control assembly, and the Y-direction photoelectric sensor is used to detect the position of the workbench 21. By setting the Y-direction photoelectric sensor, it is convenient for the measurement and control assembly to accurately know the position of the workbench 21, and then determine whether the workbench 21 is in the initial position. The measurement and control assembly drives the Y-direction return assembly 45 to move based on the judgment. Optionally, the position information of the workbench 21 can be displayed in real time on the computer, so that the operator can determine whether the table assembly 2 is returned to the position, and then proceed to the next step.

[0057] In order to ensure that at least part of the table assembly 2 is not disturbed in the X and Y directions when performing the Z-direction impact test, and not disturbed in the Z direction when performing the X and Y-direction impact tests, as Figure 2 As shown, the workbench 21 can be locked on the support plate 22 or unlocked from the support plate 22. Specifically, when performing X-direction and Y-direction tests, the workbench 21 is locked with the support plate 22; when performing Z-direction tests, the workbench 21 is unlocked from the support plate 22, and the Z-direction propulsion mechanism 43 drives the workbench 21 to move relative to the support plate 22. Optionally, the workbench 21 can be locked on the support plate 22 by threaded connection, latch connection, or other fastener connection.

[0058] like Figure 5As shown, the support plate 22 is provided with an avoidance notch 221, and the workbench 21 also includes a Z-direction response head 216, which is connected to the lower side of the workbench body 211 and can extend from the avoidance notch 221 to the lower side of the support plate 22 to impact the Z-direction waveform generator 33. The impact device also includes a Z-direction guide assembly 53 and a Z-direction support assembly 13, wherein the Z-direction guide assembly 53 is connected to the lower side of the workbench 21 and can drive the workbench 21 to slide or lock along the Z-direction relative to the support plate 22. The Z-direction support assembly 13 is arranged below the avoidance notch 221, and the Z-direction waveform generator 33 is installed on the Z-direction support assembly 13 to be arranged opposite to the Z-direction response head 216. Optionally, the connection method between the workbench 21 and the Z-direction guide assembly 53 can be a threaded connection, a latch connection or other fastener connection.

[0059] like Figure 5 As shown, in this embodiment, the Z-direction waveform generator 33 includes a Z-direction second elastic member 331, and the Z-direction second elastic member 331 is arranged along the Z direction relative to the Z-direction response head 216 to ensure that the workbench 21 can generate the half-sine pulse required for the test after the Z-direction waveform generator 33 collides with the workbench 21. In this embodiment, one Z-direction second elastic member 331 is provided. In other embodiments, two, three, four or more Z-direction second elastic members 331 may be provided, which is not specifically limited here, as long as the half-sine pulse of the impact test can be obtained.

[0060] In order to ensure that the workbench 21 strikes accurately along the Z direction, a slot is provided on the end face of the Z-direction response head 216 facing the Z-direction waveform generator 33. The Z-direction waveform generator 33 also includes a Z-direction correction member (not shown in the figure), which is plugged into the Z-direction second elastic member 331, and the end of the Z-direction correction member protrudes from the Z-direction second elastic member 331 toward the end face of the workbench 21. In the process of the workbench 21 striking the Z-direction waveform generator 33 along the Z direction, the Z-direction correction member is first inserted into the slot of the Z-direction response head 216, thereby guiding the striking direction of the workbench 21, and then the Z-direction response head 216 strikes the Z-direction second elastic member 331 again, ensuring the striking direction is accurate, thereby ensuring the reliability of the test results.

[0061] The measurement and control component is electrically connected to the Z-direction guide component 53 for controlling the locking and unlocking of the Z-direction guide component 53 relative to the support plate 22 ; the measurement and control component is electrically connected to the Z-direction propulsion mechanism 43 for controlling the height of the Z-direction propulsion mechanism 43 to lift the workbench 21 .

[0062] like Figure 5As shown, the working process of the Z-direction impact test is roughly as follows: the Z-direction guide component 53 is unlocked relative to the support plate 22; the measurement and control component controls the output end of the Z-direction propulsion mechanism 43 to extend upward into the avoidance gap 221 to contact the workbench 21, and the Z-direction propulsion mechanism 43 pushes the workbench 21 upward to a specified height; the Z-direction guide component 53 is locked relative to the support plate 22, thereby locking the height of the workbench 21; the measurement and control component controls the output end of the Z-direction propulsion mechanism 43 to drop to the lowest position (i.e., lower than the position of the Z-direction waveform generator 33) for avoidance; the Z-direction guide component 53 is unlocked relative to the support plate 22, and the workbench 21 falls along the Z-direction together with the Z-direction guide component 53 under the action of its own gravity, and the Z-direction response head 216 hits the Z-direction waveform generator 33 to obtain the half-sine pulse required for the impact test.

[0063] In order to ensure that the Z-direction guide assembly 53 can be locked or unlocked with the support plate 22 at an appropriate time, as shown in FIG. Figure 5 As shown, the impact device further includes a third connecting assembly 531, which is mounted on the support plate 22 and connected to the lower side of the support plate 22. The Z-direction guide assembly 53 is slidably matched with the third connecting assembly 531, and the third connecting assembly 531 can selectively lock or unlock the Z-direction guide assembly 53. In this embodiment, four Z-direction guide assemblies 53 are provided, and correspondingly, four third connecting assemblies 531 are provided. Optionally, the number of Z-direction guide assemblies 53 is not unique, and is not specifically limited here.

[0064] In this embodiment, the Z-direction guide assembly 53 is a guide rod, one end of which is fixedly connected to the workbench body 211. The third connecting assembly 531 includes a third guide sleeve 5311 and a third brake member 5312. The third guide sleeve 5311 is sleeved on the Z-direction guide assembly 53 and connected to the support plate 22.

[0065] The output end of the third brake member 5312 extends radially along the Z-direction guide assembly 53 and can move relative to the third guide sleeve 5311. The output end of the third brake member 5312 is electrically connected to the measurement and control assembly, and the measurement and control assembly can control the output end of the third brake member 5312 to move radially along the third guide sleeve 5311. Optionally, the third brake member 5312 can be a cylinder, the cylinder body of the cylinder is connected to the third guide sleeve 5311, and the piston of the cylinder can abut against the Z-direction guide assembly 53 to lock the Z-direction guide assembly 53. In some embodiments, the third brake member 5312 can also be a hydraulic cylinder, and the piston of the hydraulic cylinder can abut against the Z-direction guide assembly 53 to lock the Z-direction guide assembly 53. Optionally, the guide rod can be connected to the workbench body 211 by threaded connection, pin connection or other fastener connection, and the third guide sleeve 5311 can be connected to the support plate 22 by threaded connection, pin connection or other fastener connection.

[0066] During the Z-direction impact test and when the Z-direction propulsion mechanism 43 lifts the workbench 21 to a specified height, the measurement and control component controls the output end of the third brake member 5312 to move radially along the third guide sleeve 5311, and abuts against to lock the Z-direction guide assembly 53, so that the height of the Z-direction guide assembly 53 is locked, that is, the height of the workbench 21 is locked; when the Z-direction propulsion mechanism 43 drops to the lowest point, the measurement and control component controls the output end of the third brake member 5312 to release the abutment against the Z-direction guide assembly 53, and the workbench 21 is impacted by its own gravity along the Z-direction against the Z-direction waveform generator 33.

[0067] In some embodiments, the Z-direction propulsion mechanism 43 includes a propulsion cylinder, and the height of the workbench 21 can be changed by changing the extension length of the piston rod of the propulsion cylinder. In this embodiment, the Z-direction propulsion mechanism 43 includes a linear motor (not shown) and a lifting member 431. The linear motor can drive the lifting member 431 to move in the vertical direction and lift the workbench 21. The specific propulsion method of the Z-direction propulsion mechanism 43 is not limited here. The Z-direction propulsion mechanism 43 is electrically connected to the measurement and control component. The operation of the measurement and control component can control the lifting height of the workbench 21, and the height status of the workbench 21 can be displayed in real time in the measurement and control component.

[0068] Alternatively, if Figure 1-Figure 2 As shown, a support assembly propulsion mechanism 54 is also provided on the bottom plate 121 of the frame 12, and the support assembly propulsion mechanism 54 is connected to the Z-direction support assembly 13, and is used to drive the Z-direction support assembly 13 to move in the horizontal direction. The measurement and control component is electrically connected to the support assembly propulsion mechanism 54, and controls the movement of the support assembly propulsion mechanism 54 to drive the Z-direction support assembly 13 to slide to one side of the bottom plate 121 along the X direction, so as to facilitate the operator to assemble or replace the Z-direction waveform generator 33.

[0069] In some embodiments, the X-axis propulsion mechanism 41 and the Y-axis propulsion mechanism 42 both include a cylinder assembly 411, which is mounted on the frame 12, and the output end of the cylinder assembly 411 is arranged opposite to the table assembly 2. The output end of the cylinder assembly 411 can quickly impact the table assembly 2 to move, so that the table assembly 2 hits the waveform generator. Specifically, the cylinder assembly 411 includes a first cylinder body 4111 and a piston rod 4112, the piston rod 4112 can reciprocate in the first cylinder body 4111, and is arranged opposite to the table assembly 2, and the first cylinder body 4111 is provided with a connecting hole 4113, which is used to communicate with an external air source to push the piston rod 4112 to hit the workbench 21.

[0070] For the impact test in the X-direction and the Y-direction, in addition to adjusting the semi-sine pulse generated by the impact test by changing the thickness and stiffness of the second elastic member, the semi-sine pulse can also be adjusted by adjusting the impact force of the X-direction propulsion mechanism 41 and the Y-direction propulsion mechanism 42 on the table assembly 2.

[0071] In this regard, Figure 6 As shown, the X-axis propulsion mechanism 41 and the Y-axis propulsion mechanism 42 both include a quick-release assembly 412, and the quick-release assembly 412 includes a second cylinder body 4121 and a quick-release valve 4122. The second cylinder body 4121 is connected to the first cylinder body 4111 and can be connected to the first cylinder body 4111 through a connecting hole 4113. The quick-release valve 4122 can selectively block or open the connecting hole 4113, and the second cylinder body 4121 is connected to an external high-pressure gas source.

[0072] The actual working process of the X-axis propulsion mechanism 41 is roughly as follows: the measurement and control component controls the quick release valve 4122 to block the connecting hole 4113; the gas storage tank 4124 is opened to input high-pressure gas into the second cylinder 4121 through the air inlet pipe 4125, and when the internal pressure of the second cylinder 4121 reaches the specified pressure, the pressure is maintained; when it is necessary to impact the workbench 21, the measurement and control component controls the quick release valve 4122 to open, and under the action of the high-pressure gas in the second cylinder 4121, the piston rod 4112 can quickly obtain the initial speed and impact the table assembly 2; after the work is completed, the high-pressure gas in the first cylinder 4111 is discharged, and the piston rod 4112 is automatically retracted for the next impact test.

[0073] It is understandable that the quick release valve 4122 is closed in the initial state, and high-pressure gas is pre-stored in the second cylinder body 4121, so that after the quick release valve 4122 is opened, the piston rod 4112 can impact the table assembly 2 more quickly. The cylinder assembly 411 is electrically connected to the measurement and control assembly. The operator can start and control the cylinder assembly 411 and the quick release assembly 412 by operating the measurement and control assembly. The measurement and control assembly can control the amount of high-pressure gas introduced, and then control the internal pressure of the second cylinder body 4121. By controlling the internal pressure of the second cylinder body 4121, the initial impact force of the piston rod 4112 can be changed, and the initial acceleration of the piston rod 4112 hitting the table assembly 2 can be further adjusted. The Y-direction propulsion mechanism 42 has the same structure as the X-direction propulsion mechanism 41, and will not be repeated here.

[0074] like Figure 6 As shown, specifically, the quick release assembly 412 also includes an inner cylinder 4123, an air storage tank 4124 and an air intake pipe 4125. The inner cylinder 4123 is disposed inside the second cylinder 4121, and has a smaller capacity and volume than the second cylinder 4121, and has the same lower end cover as the second cylinder 4121. The inner cylinder 4123 can selectively connect to the outside air or connect to a high-pressure gas tank. After the high-pressure gas is introduced into the inner cylinder 4123, the quick release valve 4122 can be driven to reciprocate in the inner cylinder 4123.

[0075] In other embodiments, the X-axis propulsion mechanism 41 and the Y-axis propulsion mechanism 42 include a cylinder assembly or a motor. The specific propulsion method is not specifically limited here. It is sufficient to adjust the impact force of the impact test to obtain the required half-sine impact pulse.

[0076] like Figure 1 As shown, in order to more accurately simulate the impact test environment, the impact equipment further includes an environmental chamber 7 and a base 6. The base 6 is constructed as a box with an upper opening, the frame 12 is installed inside the base 6, and the environmental chamber 7 is installed above the base 6 and surrounded by the base 6 to form a test cavity to avoid being affected by the outside world.

[0077] The operator can arrange corresponding structures in the test chamber to simulate different temperature, humidity, smoke and other environments. The above corresponding structures are all electrically connected to the measurement and control component, and the actual use environment of the required simulated impact test can be selected by operating the measurement and control component. Correspondingly, the environmental box 7 is also provided with corresponding detection components, which are used to detect the state information of temperature, humidity and smoke in the environmental box 7. The detection components are electrically connected to the measurement and control component so that the measurement and control component can accurately know whether the current state in the environmental box 7 has reached the state to be set.

[0078] In some embodiments, the impact device further includes a mounting bracket 11, which is connected to the base 6, and the environmental chamber 7 is suspended on the mounting bracket 11, so that the environmental chamber 7 is above the table assembly 2 and can more accurately perform impact tests under different environments.

[0079] like Figure 1 As shown, in order to ensure the reliability of the test chamber seal, the impact device further includes a flexible seal 8, which is used to seal the table assembly 2 and the environmental chamber 7. Specifically, the environmental chamber 7 is sealed and connected to the table assembly 2 through the flexible seal 8. The flexible seal 8 can be a soft rubber part, such as nitrile rubber, chloroprene rubber, silicone rubber, etc., and the specific rubber material is not specifically limited.

[0080] In this embodiment, the base 6 includes two layers of shells, which are welded by structural steel, and concrete is cast between the two layers of shells, with a total weight of 80 tons and an overall size of about 6100mm×7100mm×3500mm, thereby ensuring the reliability of the structure.

[0081] The impact equipment also includes a vibration isolation buffer. The bottom and surrounding surfaces of the base 6 are equipped with vibration isolation buffers, which can seal the impact test environment and isolate it from the outside world, ensure the rigor of the temperature test, and not be disturbed by the outside world, so that the impact test results are more accurate and have less impact on the external environment.

[0082] Since the impact test is highly destructive to the environment, the vibration isolation buffer material can be optionally made of composite vibration isolation rubber to achieve good vibration isolation and vibration absorption between the impact device and the surrounding environment. The structure, material and size of the specific base 6 are not specifically limited, as long as it can cooperate with the table assembly 2 to have a good vibration isolation effect.

[0083] In order to avoid human error during impact testing, the impact equipment also has the function of setting protection to limit the operable range of the measurement and control components. When human error occurs, the computer will give a prompt.

[0084] In order to avoid accidental entry of personnel during impact test, the impact equipment also has a safety protection function. A grating-type safety isolation fence is set outside the impact equipment. The grating-type safety isolation fence is electrically connected to the measurement and control component. When it senses that an object has passed through, the infrared rays of the grating-type safety isolation fence are intercepted and blocked. The measurement and control component can stop the impact equipment from working urgently to avoid the occurrence of safety accidents.

[0085] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
