Description

Technical Field

[0001] This utility model relates to the field of pyrotechnics testing technology, and in particular to a collision testing device and system for testing the energy storage element of an electronic detonator. Background Technology

[0002] Currently, electronic detonators are widely used in tunnel excavation, hazard removal blasting, demolition blasting, rock and ore separation, open-pit mine blasting, and other applications. The electronic control module in an electronic detonator is the detonation control part, and the stability of the electronic control module directly affects the stability of the electronic detonator. The electronic control module mainly includes a control circuit board and electronic components such as an integrated control chip, ignition element, and energy storage capacitor installed on the control circuit board.

[0003] Furthermore, in the process of manufacturing electronic detonators, in order to ensure the reliability of the electronic detonator's performance, a series of performance tests need to be carried out on the electronic detonator. Among them, testing the power loss of the energy storage capacitor on the electronic control module inside the electronic detonator after the electronic detonator is struck is one of the key test items.

[0004] Furthermore, in existing technologies, to test the power loss of the energy storage capacitor on the electronic control module inside an electronic detonator after the detonator is struck, an electronic detonator sample is mounted on a rotating frame of a collision testing device. A drive motor drives the rotating frame to rotate, causing the electronic detonator sample to rotate. When the rotational speed of the electronic detonator sample reaches the required speed, the drive motor stops driving the rotating frame, and the electronic detonator sample continues to rotate until it collides with a collision baffle to create a collision. The tester observes the voltage curve changes of the energy storage capacitor on an oscilloscope during the collision process and then analyzes the voltage of the energy storage capacitor... The voltage drop amplitude of the energy storage capacitor can be obtained by analyzing the voltage curve variation. However, the uniformity of the rotation of the rotating frame driven by the drive motor is poor, and the rotational speed of the electronic detonator sample colliding with the collision baffle is unstable, resulting in unstable collision force. The consistency of the rotational speed and collision force of the electronic detonator sample colliding with the collision baffle is poor, affecting the accuracy of the collision test results. Furthermore, for the same electronic detonator sample, when switching between different collision surfaces to collide with the collision baffle, it is difficult to ensure the consistency of the rotational speed and collision force of the electronic detonator sample colliding with the collision baffle with different collision surfaces, which also affects the accuracy of the collision test results. Therefore, there is an urgent need for a collision test device that can improve the accuracy of collision test results. Summary of the Invention

[0005] The purpose of this utility model is to overcome at least one deficiency of the prior art and provide a collision test device for testing electronic detonator energy storage components that is beneficial to improving the accuracy of collision test results. In addition, a collision test system for testing electronic detonator energy storage components is also provided.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: According to one aspect of this application, a collision testing apparatus for testing energy storage elements of electronic detonators is provided, comprising: Support frame; A rotary drive device is mounted on the support frame, and the rotary drive device is provided with a rotary drive shaft; A rotating frame is provided with a rotating connecting part in the middle of the rotating frame. The rotating connecting part is connected to the rotating drive shaft. The rotating frame can rotate around the rotation center axis of the rotating drive shaft under the drive of the rotating drive shaft connected to the rotating connecting part. After the rotating drive device stops driving, the rotating frame can continue to rotate based on the rotational inertia until it stops rotating under the action of resistance. A clamping mechanism is mounted on the rotating frame, and the clamping mechanism is provided with a clamping mounting part for mounting and clamping the electronic detonator sample; A counterweight is installed on the rotating frame. The counterweight is used to balance the total weight of the clamping mechanism and the electronic detonator sample. When the rotating frame rotates around the rotation center axis of the rotating drive shaft connected to the rotating connection part, the electronic detonator sample installed on the clamping mechanism can smoothly perform circular motion around the rotation center axis of the rotating drive shaft. After the rotating drive device stops driving, the electronic detonator sample can continue to perform circular motion with the rotating frame based on the rotational inertia until it stops under the action of resistance.

[0007] In this embodiment, a counterweight is installed on the rotating frame to balance the total weight of the clamping mechanism and the electronic detonator sample. This facilitates adjusting the alignment of the center of gravity of the rotating body (comprising the rotating frame, clamping mechanism, electronic detonator sample, and counterweight) with the axis of rotation. This improves the alignment of the center of gravity of the rotating body with the axis of rotation, allowing the electronic detonator sample mounted on the clamping mechanism to move smoothly in a circular motion around the axis of rotation of the rotating drive shaft. This also improves the stability and uniformity of the rotating frame's rotation driven by the rotating drive shaft. Furthermore, the stability and uniformity of the rotating frame's continued rotation based on its rotational inertia after the rotating drive stops ensures that the electronic detonator sample collides with the blocking block at a stable rotational speed, resulting in a stable collision force. Additionally, the rotational speed and collision force when the electronic detonator sample collides with the blocking block can be standardized, improving the accuracy of the collision test results.

[0008] In addition, based on the above technical solution, the present invention can be further improved as follows, and can also have the following additional technical features.

[0009] According to one embodiment of this application, the collision testing apparatus for testing electronic detonator energy storage elements further includes: A blocking block is disposed on the circumferential outer side of the rotating frame; A displacement driving device is disposed on the circumferential outer side of the rotating frame and located outside the blocking block. The displacement driving device is provided with a displacement driving part, and the blocking block is connected to the displacement driving part. Under the drive of the displacement driving part, the blocking block can have a blocking position and an avoidance position relative to the electronic detonator sample mounted on the clamping mounting part. When the blocking block is in the blocking position, the blocking block extends into the path range of the electronic detonator sample during its circular motion and can block the electronic detonator sample in circular motion, causing a collision. When the blocking block is in the avoidance position, the blocking block is outside the path range of the electronic detonator sample during its circular motion.

[0010] In this embodiment, a displacement driving device is provided, which has a displacement driving part. The blocking block is connected to the displacement driving part, which makes it easy to control the blocking block to switch between the blocking position and the avoidance position through the displacement driving device, which is beneficial to the automation of collision testing.

[0011] According to one embodiment of this application, in a direction perpendicular to the rotation center axis of the rotation drive shaft, the center of gravity of the total weight of the clamping mechanism and the electronic detonator sample is axially symmetrically distributed with respect to the center of gravity of the counterweight relative to the rotation center axis, and the center of gravity of the rotating frame is on the rotation center axis.

[0012] In this embodiment, the center of gravity of the total weight of the clamping mechanism and the electronic detonator sample is symmetrically distributed with respect to the axis of rotation of the counterweight. The center of gravity of the rotating frame is on the axis of rotation, which is beneficial to make the center of gravity of the total weight of the rotating body, including the rotating frame, clamping mechanism, electronic detonator sample, and counterweight, coincide with the axis of rotation. This is beneficial to improving the stability and uniformity of the rotation of the rotating body, including the rotating frame, clamping mechanism, electronic detonator sample, and counterweight.

[0013] According to one embodiment of this application, the weight of the clamping mechanism is M1, the weight of the electronic detonator sample is M2, and the weight of the counterweight is M3, wherein M3 = M1 + M2.

[0014] In this embodiment, the weight of the clamping mechanism is M1, the weight of the electronic detonator sample is M2, and the weight of the counterweight is M3. M3 = M1 + M2, which is beneficial to achieve an axisymmetric distribution of the weight center of the total weight of the clamping mechanism and the electronic detonator sample relative to the rotation center axis of the counterweight.

[0015] According to one embodiment of this application, the counterweight is provided in multiple parts, and the multiple counterweights and the clamping mechanism are circumferentially equidistantly spaced in the circumferential direction. In the direction perpendicular to the rotation center axis of the rotary drive shaft, the weight center of the multiple counterweights is coplanar with the weight center of the total weight of the clamping mechanism and the electronic detonator sample, and the distances to the rotation center axis of the rotary drive shaft are equal.

[0016] In this embodiment, the multiple counterweights and clamping mechanism are circumferentially spaced at equal intervals. The center of gravity of the multiple counterweights is coplanar with the center of gravity of the total weight of the clamping mechanism and the electronic detonator sample, and their distances from the rotation center axis of the rotary drive shaft are equal. This is beneficial because the center of gravity of the total weight of the rotating body, including the rotating frame, clamping mechanism, electronic detonator sample, and multiple counterweights, coincides with the rotation center axis, thereby improving the stability and uniformity of the rotation of the rotating body. Furthermore, the presence of multiple counterweights further improves the uniformity of the weight distribution of the rotating body.

[0017] According to one embodiment of this application, the collision testing apparatus for testing electronic detonator energy storage elements further includes: A pressure sensor is installed on the blocking block, and the pressure sensor is used to collect the pressure generated when the blocking block collides with the electronic detonator sample that is moving in a circular motion.

[0018] In this embodiment, a pressure sensor is installed on the blocking block, which facilitates the collection of pressure generated when the blocking block collides with the circularly moving electronic detonator sample. This is beneficial for real-time collection of the collision force generated when the blocking block collides with the circularly moving electronic detonator sample during the test process, and also facilitates the unification and monitoring of the collision force.

[0019] According to one embodiment of this application, the clamping mechanism includes: An angle adjustment drive device is installed on the rotating frame. The angle adjustment drive device is provided with an angle adjustment drive part. The clamping mounting part is installed on the angle adjustment drive part. The clamping mounting part can rotate circumferentially under the drive of the angle adjustment drive part to adjust the angle, so that the electronic detonator sample installed on the clamping mounting part rotates with the rotation of the clamping mounting part and the angle is adjusted.

[0020] In this embodiment, the angle adjustment drive device is provided with an angle adjustment drive unit, and the clamping mounting unit is installed on the angle adjustment drive unit. During the testing of the electronic detonator sample, when it is necessary to adjust the installation angle of the electronic detonator sample, the angle adjustment drive unit can drive the clamping mounting unit to rotate circumferentially to adjust the angle installed on the clamping mounting unit. This facilitates the adjustment of the angle of the electronic detonator sample, thereby enabling the switching of different collision surfaces with the blocking block. It also helps to automate the angle adjustment and improves the accuracy of adjusting the collision surface of the electronic detonator sample with the blocking block.

[0021] According to one embodiment of this application, the collision testing apparatus for testing electronic detonator energy storage elements further includes: An angle adjustment control unit is provided, wherein the angle adjustment drive device is electrically connected to the angle adjustment control unit, and the angle adjustment control unit is used to control the angle by which the angle adjustment drive unit drives the clamping mounting part to rotate circumferentially.

[0022] In this embodiment, the angle adjustment drive device is electrically connected to the angle adjustment control unit. During the testing of the electronic detonator sample, when it is necessary to adjust the installation angle of the electronic detonator sample, the angle adjustment control unit can control the angle adjustment drive device to drive the clamping mounting part to rotate circumferentially. This allows the electronic detonator sample mounted on the clamping mounting part to rotate with the rotation of the clamping mounting part and adjust the angle. This enables the switching of different collision surfaces of the electronic detonator sample with the blocking block, facilitates the automation of angle adjustment, and improves the accuracy of adjusting the collision surface of the electronic detonator sample with the blocking block.

[0023] According to one embodiment of this application, the collision testing apparatus for testing electronic detonator energy storage elements further includes: A conductive contact sliding connector is sleeved on the outer periphery of the rotary drive shaft and located between the support frame and the rotary frame. One end of the connecting lead connected to the electronic detonator sample near the conductive contact sliding connector is conductively connected to the rotating conductive ring of the conductive contact sliding connector.

[0024] In this embodiment, a conductive contact sliding connector is provided. The end of the connecting lead connected to the electronic detonator sample is conductively connected to the rotating conductive ring of the conductive contact sliding connector. When using the connecting lead to connect the electronic detonator sample, it is beneficial to avoid the connecting lead from becoming tangled during the rotation of the rotating frame.

[0025] According to another aspect of this application, a collision testing system for testing electronic detonator energy storage elements is provided, comprising: The aforementioned collision testing device for testing energy storage components of electronic detonators; A collision control unit is provided, wherein the rotary drive device is electrically connected to the collision control unit, and the collision control unit is used to control the start, stop, rotational drive direction, and rotational drive speed of the rotary drive device. A charging control unit is provided, wherein the electronic detonator sample is electrically connected to the charging control unit, and the charging control unit is used to control the charging and stopping of charging of the electronic detonator sample.

[0026] The collision testing system for testing electronic detonator energy storage components in this embodiment includes the aforementioned collision testing device for testing electronic detonator energy storage components. The rotation drive device is electrically connected to the collision control unit, which facilitates the control of the rotation drive device's start, stop, rotation direction, and rotation speed via the collision control unit. Furthermore, the electronic detonator sample is electrically connected to the charging control unit, which facilitates the charging and stopping control of the electronic detonator sample via the charging control unit. This improves the automation of the collision test, reduces human intervention, and helps avoid reducing the accuracy of test results due to human error.

[0027] According to one embodiment of this application, the collision test system for testing electronic detonator energy storage elements further includes: An oscilloscope is disposed on the outside of the rotating frame. The oscilloscope is electrically connected to the electronic detonator sample. The oscilloscope is used to acquire the voltage of the energy storage element disposed in the electronic detonator sample. The oscilloscope is also used to display a voltage curve that reflects the voltage of the energy storage element disposed in the electronic detonator sample.

[0028] In this embodiment, an oscilloscope is provided and electrically connected to the electronic detonator sample. This facilitates the acquisition of the voltage of the energy storage element installed in the electronic detonator sample through the oscilloscope, and also facilitates the display of a voltage curve that reflects the voltage of the energy storage element installed in the electronic detonator sample through the oscilloscope.

[0029] According to one embodiment of this application, the collision test system for testing electronic detonator energy storage elements further includes: A voltage curve monitoring and processing unit is included, with the oscilloscope electrically connected to it. Before the electronic detonator sample collides with the blocking block, the voltage curve monitoring and processing unit monitors the charging voltage curve of the energy storage element during the charging phase, and also monitors the voltage holding voltage curve of the energy storage element during the voltage holding phase. If either the charging voltage curve or the voltage holding voltage curve is abnormal, the test is terminated and a notification is issued; if both the charging voltage curve and the voltage holding voltage curve are normal, the test continues. During the collision between the electronic detonator sample with a first rotational speed and the blocking block, the voltage curve monitoring and processing unit captures the instant T of the collision. The voltage curve image is captured, and the maximum voltage drop amplitude at the moment of impact T is calculated based on the captured voltage curve image. After the electronic detonator sample collides with the blocking block, the voltage curve monitoring and processing unit captures the voltage curve image from the moment of impact T to the first collision duration T+T1, and calculates the maximum voltage drop amplitude from the moment of impact T to the first collision duration T+T1 based on the captured voltage curve image. The voltage drop rate from the moment of impact T to the first collision duration T+T1 is calculated based on the obtained maximum voltage drop amplitude and the calculation time corresponding to the maximum voltage drop amplitude. The voltage curve image contains the voltage curve. The shock response spectrum analysis unit is used to obtain the shock response spectrum based on the collision data of the electronic detonator sample colliding with the blocking block and the set single-degree-of-freedom system parameters. The shock response spectrum is used to analyze the shock resistance performance of the energy storage element.

[0030] In this embodiment, a voltage curve monitoring and processing unit is provided to facilitate the monitoring of the charging voltage curve of the energy storage element during the charging phase, as well as the monitoring of the voltage holding voltage curve during the voltage holding phase. Furthermore, the voltage curve monitoring and processing unit can capture voltage curve images and calculate the voltage drop amplitude and voltage drop rate based on the captured voltage curve images. Furthermore, this embodiment includes an impact response spectrum analysis unit, which facilitates the acquisition of the impact response spectrum based on the collision data of the electronic detonator sample colliding with the blocking block and the set single-degree-of-freedom system parameters. This allows for the analysis of the impact resistance performance of the energy storage element using the obtained impact response spectrum. Attached Figure Description

[0034] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0036] One aspect of this application provides a collision testing device for testing energy storage elements in electronic detonators, such as... Figures 1 to 7 As shown, it includes: Support frame 1; A rotary drive device is mounted on the support frame 1, and a rotary drive shaft 20 is provided on the rotary drive device; The rotating frame 3 has a rotating connection part in the middle, which is connected to the rotating drive shaft 20. The rotating frame 3 can rotate around the rotation center axis of the rotating drive shaft 20 under the drive of the rotating drive shaft 20 connected to the rotating connection part. After the rotating drive device stops driving, the rotating frame 3 can continue to rotate based on the rotational inertia until it stops rotating under the action of resistance. The clamping mechanism 4 is mounted on the rotating frame 3. The clamping mechanism 4 is provided with a clamping mounting part for mounting and clamping the electronic detonator sample 8. The counterweight 5 is installed on the rotating frame 3. The counterweight 5 is used to balance the total weight of the clamping mechanism 4 and the electronic detonator sample 8. When the rotating frame 3 rotates around the rotation center axis of the rotating drive shaft 20 connected to the rotating connection part, the electronic detonator sample 8 installed on the clamping mechanism 4 can smoothly make circular motion around the rotation center axis of the rotating drive shaft 20. After the rotating drive device stops driving, the electronic detonator sample 8 can continue to make circular motion with the rotating frame 3 based on the rotational inertia until it stops making circular motion under the action of resistance.

[0037] In this embodiment, as Figures 1 to 7 As shown, in this embodiment, a counterweight 5 is installed on the rotating frame 3 to balance the total weight of the clamping mechanism 4 and the electronic detonator sample 8. This facilitates adjusting the alignment of the center of gravity of the rotating body (comprising the rotating frame 3, clamping mechanism 4, electronic detonator sample 8, and counterweight 5) with the axis of rotation. This improves the alignment of the center of gravity of the rotating body with the axis of rotation, thereby facilitating the rotation of the electronic detonator sample 8 mounted on the clamping mechanism 4. The smooth circular motion of the rotation center axis of the drive shaft 20 is beneficial to improving the stability and uniformity of the rotational motion of the drive shaft 20 driving the rotating frame 3. Furthermore, after the rotational drive device stops, the stability and uniformity of the rotating frame 3 continuing to rotate based on the inertia of the rotational motion are beneficial to the electronic detonator sample 8 colliding with the blocking block 61 at a stable rotational speed, thereby facilitating the acquisition of a stable collision force. It can also unify the rotational speed and collision force when the electronic detonator sample 8 collides with the blocking block 61, improving the accuracy of the collision test results.

[0038] In this embodiment, as Figure 1 and Figure 2 As shown, the support frame 1 in this embodiment includes a support base 10, a front support frame 11, and a rear support frame 12. The support base 10 has a cuboid structure. A rotational clearance space is formed between the front support frame 11 and the rear support frame 12. The front support frame 11 includes two inclined support beams and a horizontal support beam. The lower ends of the two inclined support beams are fixedly connected to the upper front side of the support base 10, and the horizontal support beam is horizontally connected above the two inclined support beams. The rear support frame 12 includes two inclined support beams and a horizontal support beam. The lower ends of the two inclined support beams are fixedly connected to the upper rear side of the support base 10, and the horizontal support beam is horizontally connected above the two inclined support beams. The horizontal support beams are at the same height as the horizontal support beams.

[0039] Furthermore, such as Figure 1 and Figure 2 As shown, the rotary drive device in this embodiment is specifically a rotary drive motor 2, which is mounted on the upper side of the rear support frame 12 via a fixed base. The rotary drive motor 2 is provided with a rotary drive shaft 20, which is specifically a stepped shaft that extends forward. Furthermore, the front end of the rotary drive shaft 20 is rotatably supported by a bearing seat 13 mounted above the front support frame 11, and the rear end of the rotary drive shaft 20 is rotatably supported by a bearing seat 13 mounted above the rear support frame 12.

[0040] Furthermore, such as Figure 1 and Figure 2 As shown, the rotating frame 3 in this embodiment includes support arms 30 and connecting arms 31. Four support arms 30 are provided in this embodiment. The first end of each support arm 30 is positioned close to the rotating drive shaft 20, and a shaft hole 35 is provided on the first end of each support arm 30. They are stacked and sleeved around the outer periphery of the rotating drive shaft 20 in the front-to-back direction and arranged at equal intervals in the circumferential direction. The first end of each support arm 30 is locked and fixed to the middle of the rotating drive shaft 20 by two locking limit discs 33. Multiple bolts are used to lock the two locking limit discs 33 together, thus locking and fixing the first ends of the four support arms 30. The second end of each support arm 30 is positioned away from the rotating drive shaft 20, and a bolt through hole 1 is provided on the second end of each support arm 30. In this embodiment, four support arms 30 are provided, and bolt through holes 2 are provided at both ends of each support arm 30. The support arms 30 are fixedly connected between the second ends of two adjacent support arms 30 by bolts and nuts, with the bolts passing through the bolt through holes 1 and 2 that are directly opposite each other.

[0041] Furthermore, such as Figure 3 and Figure 4As shown, in order to improve the reliability of the support arm 30 mounted on the rotary drive shaft 20, a pin groove 351 is provided on the outside of the shaft hole 35 at the second end of the support arm 30. The pin groove 351 is connected to the shaft hole 35, so that the pin can be inserted into the pin groove 351 at the second end of the multiple support arms 30 to improve the reliability of the support arm 30 mounted on the rotary drive shaft 20.

[0042] Furthermore, such as Figure 3 and Figure 4 As shown, in this embodiment, the support arm 30 and the connecting arm 31 are arranged radially in the front-back direction. When there is a gap between the support arm 30 and the connecting arm 31, a washer 34 is installed at the position of the gap, and the washer 34 occupies the gap between the support arm 30 and the connecting arm 31.

[0043] In this embodiment, as Figures 1 to 4 As shown, in this embodiment, the outer radial end of the rotating frame 3 is equipped with an mounting plate 32. In this embodiment, there are four mounting plates 32. The four mounting plates 32 are respectively fixed to the bolts passing through the bolt through holes one and two that are directly opposite each other by nuts. The four mounting plates 32 are installed in the radial direction.

[0044] In this embodiment, as Figures 1 to 4 As shown, in this embodiment, the counterweight 5 is mounted on the mounting plate 32 via a mounting support 2 50. The mounting support 2 50 has an L-shaped structure and is fixedly mounted on the mounting plate 32 by bolts. In this embodiment, the counterweight 5 is fixedly mounted on the mounting support 2 50 by bolts. It should be noted that the weight of the counterweight 5 can be adjusted according to the total weight of the clamping mechanism 4 and the electronic detonator sample 8, which is beneficial to improving the stability and uniformity of the rotation of the rotating frame 3 driven by the rotating drive shaft 20.

[0045] Furthermore, the rotary drive device in this embodiment can also be other rotary drive devices, and there can be various ways to install the rotary drive device on the support frame 1; in addition, there can be various structures for the support frame 1 and the rotary frame 3 in this embodiment, as long as it is convenient to drive the rotary frame 3 to rotate and facilitates the smooth circular motion of the electronic detonator sample 8 installed on the clamping mechanism 4 around the rotation center axis of the rotary drive shaft 20.

[0046] It should be noted that the electronic detonator sample 8 in this embodiment is based on an electronic detonator product used for blasting. It is obtained by imitating and producing an electronic detonator product used for blasting. The electronic detonator sample 8 does not have an explosive function. The structure, shape and weight of the electronic detonator sample 8 are the same as those of the electronic detonator product. The basic explosive material filled in the electronic detonator sample 8 is replaced by a filler that does not have an explosive function. Furthermore, after the rotary drive device stops driving, the circular motion of the electronic detonator sample 8 is specifically a variable speed circular motion. The rotational speed of the electronic detonator sample 8 at the moment the rotary drive device stops driving is the second rotational speed. The electronic detonator sample 8 collides with the blocking block 61 at a stable first rotational speed. The first rotational speed is less than the second rotational speed. The specific speeds of the first and second rotational speeds can be set as needed.

[0047] Furthermore, in this embodiment, the rotation speed of the electronic detonator sample 8 is monitored by a speed sensor. There are various ways to arrange the speed sensor to monitor the rotation speed of the electronic detonator sample 8, and existing technologies in the field can be referenced, which will not be elaborated here. In addition, the rotation speed of the electronic detonator sample 8 can also be controlled by setting the start and stop time of the rotation drive device, so that the electronic detonator sample 8 collides with the blocking block 61 at a stable first rotation speed.

[0048] One embodiment of this application, such as Figure 1 and Figure 2 As shown, the impact testing apparatus for testing electronic detonator energy storage elements also includes: The blocking block 61 is located on the outer circumferential side of the rotating frame 3; A displacement driving device is located on the circumferential outer side of the rotating frame 3 and outside the blocking block 61. The displacement driving device is provided with a displacement driving part, and the blocking block 61 is connected to the displacement driving part. Under the drive of the displacement driving part, the blocking block 61 can have a blocking position and a avoidance position relative to the electronic detonator sample 8 mounted on the clamping mounting part. When the blocking block 61 is in the blocking position, the blocking block 61 extends into the path range of the electronic detonator sample 8 during its circular motion and can block the electronic detonator sample 8 during its circular motion, causing a collision. When the blocking block 61 is in the avoidance position, the blocking block 61 is outside the path range of the electronic detonator sample 8 during its circular motion.

[0049] In this embodiment, as Figure 1 and Figure 2As shown, in this embodiment, a displacement driving device is provided, and a displacement driving part is provided on the displacement driving device. The blocking block 61 is connected to the displacement driving part, which makes it easy to control the blocking block 61 to switch between the blocking position and the avoidance position through the displacement driving device, which is beneficial to realizing the automation of collision testing.

[0050] In this embodiment, as Figure 1 and Figure 2 As shown, the displacement driving device in this embodiment includes a vertical displacement driving cylinder 6 and a horizontal displacement driving cylinder 7. The horizontal displacement driving cylinder 7 includes a cylinder body, a horizontal movable seat, and a horizontal driving rod. The cylinder body is fixedly connected to the support base 10, and the horizontal movable seat is connected to the horizontal driving rod. Specifically, a mounting support plate 14 and a mounting support plate 2 15 are horizontally mounted on the support base 10. The cylinder body is fixedly mounted on the mounting support plate 14 and the mounting support plate 2 15 through a connecting support.

[0051] Furthermore, such as Figure 1 and Figure 2 As shown, the vertical displacement driving cylinder 6 includes a cylinder body 2, a vertical movable seat 60, and a vertical driving rod. The cylinder body 2 is mounted on the horizontal movable seat of the horizontal displacement driving cylinder 7. The vertical displacement driving cylinder 6 can adjust its position in the horizontal direction under the drive of the horizontal displacement driving cylinder 7. The vertical movable seat 60 is connected to the vertical driving rod. In this embodiment, the blocking block 61 is mounted on the vertical movable seat 60. Furthermore, the specific structure of the horizontal displacement driving cylinder 7 and the vertical displacement driving cylinder 6 in this embodiment can refer to the push cylinder in the prior art.

The clearance through groove 472 on the elastic clamping block 47 installed in the mounting and receiving groove 431 is connected to the mounting through groove 432. Multiple elastic deformation protrusions 471 are provided on the side of the elastic clamping block 47 facing the elastic clamping block 48.
