Description

Technical Field

[0001] The present invention relates to the technical field of metrological technical instruments, and particularly relates to an on-line time measuring instrument for a clock mechanism. Background Art

[0002] A clock mechanism is a mechanism for setting time and is commonly used in time fuzes. A time fuze refers to a fuze that acts according to the set time after the ammunition is launched, thrown, or laid, and is also called a timing fuze. Time fuzes are widely used in various timed detonating ammunitions such as airburst, skip burst, explosion after penetrating the target, and explosion deep inside the target (such as defensive works, etc.). In order to ensure the smooth use, it is necessary to test the clock mechanisms of the fuzes designed in production.

[0003] After retrieval

[0004] An on-line time measuring instrument for a fuze clock mechanism, with the publication number of CN104536280A. The clock mechanism is placed in the working station of the main body. Using the original positioning holes at the bottom of the clock mechanism, insert the positioning rods on the bottom plate to position it, and press the clock mechanism tightly with a compression spring. At this time, the clock mechanism is installed and ready for inspection. When measuring the clock mechanism, push the handle to push the electrode to the starting position of the clock mechanism, then insert a pin into the jack on the release and firing assembly of the clock mechanism, and turn the release and firing assembly of the clock mechanism clockwise to the starting position as well, and clamp the electrode to connect the No. III and No. II circuits of the digital stopwatch. At this time, press the reset key "0" on the digital stopwatch to make the timing indication value on the digital stopwatch be 0. When the pin is pulled out, the release and firing assembly in the clock mechanism immediately starts counterclockwise, releases the electrode, and under the action of the return spring, the slider returns to the position of the limit screw along the slider guide plate. At the same time, the No. II and No. III circuits of the digital stopwatch are disconnected, and the digital stopwatch starts timing synchronously until the release and firing assembly of the clock mechanism moves to the stop position, the No. III and No. II circuits of the digital stopwatch are connected, and the digital stopwatch stops timing synchronously. Read the delay time of the clock mechanism from the digital stopwatch:

[0005] However, the prior art has the following deficiencies in use:

[0006] First, the electrode on the clock mechanism needs to be manually toggled to the starting position before testing. Therefore, as the number of experiments increases, it needs to be toggled by personnel multiple times. Therefore, when the number of clock mechanisms in the experiment is large, the workload of personnel toggling will also increase.

[0007] Secondly, when the release and firing component on the clock mechanism starts immediately in the counterclockwise direction, the power it relies on is its own reaction force, while the power source for the electrode reset is the pulling force of the spring on its surface. Therefore, during the detection process, it is easy to have a problem of inconsistency between the speed generated by the pulling force of the spring and the moving speed of the release and firing component itself, which will also affect the accuracy of the measurement results. Summary of the Invention

[0008] The purpose of the present invention is to provide an on-line time measuring instrument for a clock mechanism to solve the problems raised in the prior art.

[0009] To achieve the above object, the present invention adopts the following technical solutions: An on-line time measuring instrument for a clock mechanism includes an experimental table, a clock mechanism, a dial rod, and a digital electronic stopwatch. On both sides of the experimental table top, there are respectively fixedly connected a clamping mechanism for clamping the clock mechanism and a support mechanism for installing the dial rod and the digital electronic stopwatch. The clamping mechanism is used to clamp clock mechanisms of different sizes, and the support mechanism is used to drive the dial rod to insert into the jack on the release and firing component inside the clock mechanism and drive the release and firing component to rotate to the starting position.

[0010] Preferably: The clamping mechanism includes a fixed frame fixed on one side of the experimental table top.

On one side of the hollow swing arm, there is an embedded rotating connection with a block located inside the intermediate frame and hinged with the sliding card strip by a connecting rod, and on the side outside the intermediate frame, there is a fixed connection with a swinging arm. The swinging edge of the swinging arm is rotatably connected with one side of the clamping arm. At the position of the intermediate frame at the same height as the sliding card strip and at the top edge of the fixed frame away from the experimental table, guide blocks are fixedly connected.

[0013] Preferably, the support mechanism includes a support frame fixed on the other side of the experimental table top. An electric push rod is also fixed to one side of the support frame, and a rotating frame is rotatably connected to one side of the support frame through the electric push rod. The rotating frame is arranged in a U shape, and a transmission shaft fixedly connected to the telescopic end of the electric push rod is fixedly installed through the inner wall of the rotating frame near the support frame. A gear rotatably connected to the inner wall of the other side of the rotating frame is fixedly connected to one end of the transmission shaft. A rack frame meshed with the gear is inserted into the inner wall of the other side of the rotating frame, and a dial rod is inserted into one side of the outer wall of the other side of the rotating frame. An insertion bar is inserted at the center line position of the gear. One end of the insertion bar extends outward and is fixedly connected to an insertion cylinder sleeved on the dial rod and inserted into the hole wall of the jack on the release and firing assembly of the clock mechanism.

[0014] Preferably, a sliding seat is inserted through a spring rod along the horizontal direction at the top edge of the outer wall of the other side of the rotating frame. An inclined pull rod and a support rod are rotatably connected to the side surface of the sliding seat and the top edge of the outer wall of the other side of the rotating frame respectively. One side of the swinging edge of the support rod is hinged to the swinging edge of the inclined pull rod, and a traction plate is hinged between the other side of the swinging edge and the dial rod. A spring rod is also installed at the end of the other side of the rotating frame, and an inclined block misaligned with the rack frame is inserted into the inner side wall through the spring rod. A fixed shaft slidably connected to the inclined surface of the inclined block is fixedly connected to the other side of the sliding seat.

[0015] Preferably, the bottom edge of the inclined block extends outward and a steering arm and an adjusting arm are rotatably connected to the bottom edge position of the rack frame respectively. A fulcrum shaft for serving as the fulcrum of the steering arm is fixedly connected to the side of the rack frame. The planes where the steering arm and the adjusting arm rotate are arranged in parallel, and a steering rod is rotatably connected to the swinging end of the steering arm. A connecting seat is hinged to the swinging edges of the steering rod and the adjusting arm at the same time. The connecting seat slides along the length direction of the rack frame or swings within the plane parallel to the plane where the adjusting arm rotates.

[0016] Preferably, a motor is inserted into the inner wall on the other side of the rotating frame. The main shaft of the motor is fixedly connected to an L-shaped plate. An extension frame bar is also fixedly connected to the side on the other side of the rotating frame. The frame part of the extension frame bar is arranged parallel to the side surface of the rotating frame, and a sliding block is clamped inside the inner wall. A collar is rotatably connected to the side surface of the sliding block. An electric telescopic rod is arranged through the collar, the telescopic end of which penetrates through the bottom surface of the L-shaped plate and is fixedly connected to the surface of the connecting seat. An electric telescopic rod is also installed on the rotating frame and is used to drive the motor to slide.

[0017] Preferably, a clamping plate is fixedly connected to the side of the rack frame away from the bogie. The digital electric stopwatch is provided with two positive electrodes in parallel. The two positive electrodes are respectively used to be arranged at the release and firing assembly in the clock mechanism and at the clamping plate. And a negative electrode matched with the positive electrode is electrically connected to the digital electric stopwatch at the clamping plate.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] In the present invention, by arranging a bogie, the bogie and the release and firing assembly on the clock mechanism rotate simultaneously. And through the lifting of the inclined block and the cooperation with the elastic force of the spring rod connected to the sliding block, the inclined pull rod drives the support rod to swing. Under the traction of the traction plate, the shift lever will be pulled away from the clock mechanism or moved closer to the clock mechanism, that is, the shift lever automatically enters and exits the jack on the release and firing assembly of the clock mechanism.

[0020] In the present invention, by arranging a clamping mechanism, the spring can be used to ensure that the top pressing plate and the clamping arm clamp the clock mechanism, which is convenient for quickly preventing the clock mechanism. Moreover, the set rope body can make the clamping arm rotate and open synchronously when the top pressing plate rotates and opens, releasing the clamping of the clock mechanism. And by adjusting the distance between the side pressing plate and the clamping arm, clock mechanisms with different widths can be clamped.

[0021] In the present invention, by arranging a rack frame and a gear, the rack frame rotates the release and firing assembly of the clock mechanism to the starting position, and the release and firing assembly of the clock mechanism drives the rack frame to reset. It is ensured that the reset power of the rack frame comes from the rotation and reset of the release and firing assembly of the clock mechanism, that is, the moving speed of the rack frame is equal to the moving speed of the release and firing assembly of the clock mechanism, preventing different moving speeds from affecting the measurement results.

[0022] In the present invention, by providing an insertion cylinder and an insertion bar, when the lever moves to extract and release the clock mechanism to release the jack on the firing component, the contact between the insertion cylinder and the jack of the clock mechanism releasing the firing component is utilized to ensure that when the clock mechanism releases the firing component and rotates to the stop position, the rotating frame can be smoothly rotated through the connection between the insertion cylinder and the insertion bar. Moreover, when the clock mechanism releases the firing component and rotates to the stop position, the lever is aligned with the position of the jack on the clock mechanism releasing the firing component, facilitating the lever to enter the jack of the clock mechanism releasing the firing component again.

Detailed implementation manner

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1 - 10 , the present invention provides a technical solution:

[0037] An on-line time measuring instrument for a clock mechanism includes a test bench 1, a clock mechanism 2, a poking rod 32, and a digital electronic stopwatch 3. The clock mechanism 2 and the digital electronic stopwatch 3 are both prior arts, and their usage methods and operation methods refer to an on-line time measuring instrument for a fuse clock mechanism with a publication number of CN104536280A:

[0038] On both sides of the tabletop of the test bench 1, a clamping mechanism for clamping the clock mechanism 2 and a support mechanism for installing the poking rod 32 and the digital electronic stopwatch 3 are respectively fixedly connected. The clamping mechanism is used to clamp clock mechanisms 2 of different sizes, and the support mechanism is used to drive the poking rod 32 to insert into the jack of the release and firing assembly in the clock mechanism 2 and drive the release and firing assembly to rotate to the starting position.

[0039] Embodiment 1: The clamping mechanism includes a fixed frame 5 fixed on one side of the tabletop of the test bench 1. The top of the fixed frame 5 is rotatably connected with a top pressing plate 8, and the two sides of the frame body at the same height are rotatably connected with clamping arms 9. The swinging side of the top pressing plate 8 away from the test bench 1 is rotatably connected with an electric push rod 4 to the top edge of one side of the test bench 1. The clamping mechanism further includes a linkage mechanism provided on the fixed frame 5, such as Figure 1The top pressing plate 8 and the two clamping arms 9 shown are in the clamping state of the clock mechanism 2. When removing the clock mechanism 2, only by retracting the electric push rod 4 in this solution, the top pressing plate 8 can be rotated and swung away from the upper surface of the clock mechanism 2 with the rotation point of the fixed frame 5 as the fulcrum. Under the action of the linkage mechanism of the linkage mechanism, the two clamping arms 9 are simultaneously rotated and swung away from the side of the clock mechanism 2.

[0040] The specific structure of the linkage mechanism is as follows:

[0041] The linkage mechanism includes an intermediate frame 15 provided on the fixed frame 5. Inside the intermediate frame 15, a sliding strip 21 is inserted on one side at the same height as the clamping arm 9, and convex shafts 18 are fixedly connected by embedding on both sides of the other side. A hollow swing arm 17 is sleeved on the convex shaft 18. The hollow swing arm 17 can be rotated and swung by using the provided convex shaft 18. On one side of the hollow swing arm 17, a block 23 is rotatably connected by embedding and is located inside the intermediate frame 15 and is hinged to the sliding strip 21 by a connecting rod 22. On the other side outside the intermediate frame 15, a swing arm 10 is fixedly connected. As Figure 4 shown, the provided block 23 is slidably connected to the hollow part on the side surface of the hollow swing arm 17. Therefore, when the sliding strip 21 is subjected to an external force and moves away from the clock mechanism 2, under the rotational connection action of the connecting rod 22 with the sliding strip 21 and the block 23, the block 23 will be driven to move away from the clock mechanism 2, that is, the block 23 will slide along the hollow part on the surface of the hollow swing arm 17, and at the same time of sliding, the hollow swing arm 17 and the swing arm 10 fixed to the hollow swing arm 17 will be rotated and swung. The swinging side of the swing arm 10 is rotatably connected to one side of the clamping arm 9. As Figure 4 shown, one side of the clamping arm 9 is provided with a hollow, and the swing arm 10 is slidably located inside the hollow of the clamping arm 9. Therefore, when the swing arm 10 is rotated and swung, the clamping arm 9 will be forced to rotate and swing:

[0042] In addition: Guide blocks 20 are fixedly connected to the positions of the intermediate frame 15 at the same height as the sliding strip 21 and at the top edge of the fixed frame 5 away from the test bench 1. A rope body 19 is penetrated between the two guide blocks 20. The two ends of the rope body 19 are respectively fixed on the top edge of the fixed frame 5 and the sliding strip 21, and a rope pressing rod 28 in contact with the surface of the rope body 19 is fixedly connected to the top pressing plate 8. Two symmetrically arranged diagonal tension springs 24 are fixedly connected between the sliding strip 21 and the intermediate frame 15. As Figure 4 shown, by using the pulling force of the two springs 24 on the sliding strip 21, the sliding strip 21 is kept in the state as Figure 4 shown, that is, at this time, the clamping arm 9 is in the clamping state of the clock mechanism 2. The position of the sliding strip 21 is fixed by using the spring 24, and then the rope body 19 is in a taut state. The taut rope body 19 can keep the state as Figure 5the state, that is, ensuring that the top pressing plate 8 remains as Figure 5 shown in the figure, fixing the top surface of the clock mechanism 2. When the top pressing plate 8 drives the rope pressing rod 28 to swing downward due to the contraction of the electric push rod 4, the rope pressing rod 28 applies pressure to the tightened rope body 19 to bend it. Then, with the assistance of the two guiding blocks 20, the rope body 19 pulls the sliding catch 21 to move against the pulling force of the spring rod 24. In summary, the provided spring 24 can ensure that the top pressing plate 8 and the clamping arm 9 clamp the clock mechanism 2, facilitating the quick prevention of the clock mechanism 2. Moreover, with the provided rope body 19, when the top pressing plate 8 rotates and opens, the clamping arm 9 rotates and opens synchronously accordingly, releasing the clamping of the clock mechanism 2.

[0043] Embodiment 2: A rotating plate 13 is also rotatably connected to the opposite surfaces of the two clamping arms 9, and an angle arm 49 is rotatably connected therein. One side of the angle arm 49 is arranged in a T shape and is slidably connected to the side surface of the rotating plate 13 in an embedded manner. The other side is hinged to the clamping arm 9 by a spring rod 27. A side pressing plate 11 penetrating through the clamping arm 9 is rotatably connected to the swinging side of the rotating plate 13. A triangular frame 25 is inserted into the side surface of the clamping arm 9 in an embedded manner. An electric push rod 4 is also installed between the triangular frame 25 and the clamping arm 9, and the inclined surface part of the triangular frame 25 is slidably connected to the other side of the angle arm 49;

[0044] To clamp clock mechanisms 2 of different sizes, the electric push rod 4 in this solution is extended to move the triangular frame 25 towards the clock mechanism 2. During the movement, the inclined surface of the triangular frame 25 is used to push one side of the angle arm 49 to rotate and swing with the rotation point of the angle arm 49 and the clamping arm 9 as the fulcrum. When rotating and swinging, the spring rod 27 between it and the clamping arm 9 is elastically extended. By using the T-shaped protrusion on the other side of the angle arm 49 to slidably connect with the hollow part of the rotating plate 13, the rotating plate 13 can be driven to drive the side pressing plate 11 to move, adjusting the distance between the side pressing plate 11 and the clamping arm 9. Moreover, since the side pressing plate 11 is rotatably connected to the rotating plate 13 and penetrates through the clamping arm 9, when the rotating plate 13 rotates and swings, it is ensured that the side pressing plate 11 moves to clamp the side surface of the clock mechanism 2 in a state parallel to the side surface of the clamping arm 9.

[0045] Embodiment 3: The support mechanism includes a support frame 26 fixed to the other side of the tabletop of the experimental table 1. An electric push rod 4 is also fixedly connected to one side of the support frame 26, and a rotating frame 6 is rotatably connected to one side of the support frame 26 through the electric push rod 4. The telescoping of the electric push rod 4 can enable the rotating frame 6 to move relative to the clock mechanism 2, and the rotatable connection method ensures that the rotating frame 6 can also rotate relative to the telescopic end of the electric push rod 4. The rotating frame 6 is arranged in a U shape, and a transmission shaft 46 fixedly connected to the telescopic end of the electric push rod 4 is fixedly installed through the inner wall of the side of the rotating frame 6 close to the support frame 26. One end of the transmission shaft 46 is fixedly connected to a gear 45 rotatably connected to the inner wall of the other side of the rotating frame 6. A rack frame 44 meshing with the gear 45 is inserted into the inner wall of the other side of the rotating frame 6. By sliding the rack frame 44 on the rotating frame 6, the meshing gear 45 drives the transmission shaft 46 to rotate, thereby enabling the transmission shaft 46 to drive the rotating frame 6 to rotate relative to the electric push rod 4 on the support frame 26. One side of the outer wall of the other side of the rotating frame 6 is used for inserting a shift lever 32, and an insertion bar 34 is inserted at the center line position of the gear 45. One end of the insertion bar 34 extends outward and is fixedly connected to an insertion cylinder 33 sleeved on the shift lever 32 and inserted into the hole wall of the jack on the release and firing assembly of the clock mechanism 2. By extending the electric push rod 4 on the support frame 26, the rotating frame 6 can drive the shift lever 32 and the insertion cylinder 33 mounted on its surface to enter the jack on the release and firing assembly of the clock mechanism 2 in the initial state, and at this time, the release and firing assembly is in the stop position. Correspondingly, the arranged insertion bar 34 is located at the center of the release and firing assembly of the clock mechanism 2. Therefore, by driving the insertion bar 34 and the shift lever 32 to rotate a certain angle by the rotating frame 6, the release and firing assembly of the clock mechanism 2 can be toggled to the starting position. When the release and firing assembly of the clock mechanism 2 starts in the counterclockwise direction, it will drive the shift lever 32 and the insertion cylinder 33 to rotate simultaneously, thereby enabling the rotating frame 6 to rotate and reset, that is, driving the gear 45 to rotate and reset, and the sliding reset of the rack frame 44 can be realized. By using the meshing connection between the gear 45 and the rack frame 44, and the conditions that the gear 45 and the release and firing assembly of the clock mechanism 2 rotate and stop simultaneously, the rack frame 44 and the release and firing assembly of the clock mechanism 2 are kept at the same moving speed, that is, the rack frame 44 enables the release and firing assembly of the clock mechanism 2 to rotate to the starting position, and the release and firing assembly of the clock mechanism 2 drives the rack frame 44 to reset, ensuring that the reset power of the rack frame 44 comes from the rotation and reset of the release and firing assembly of the clock mechanism 2, that is, ensuring that the moving speed of the rack frame 44 is equal to the moving speed of the release and firing assembly of the clock mechanism 2;

[0046] The significance of the insertion cylinder 33 provided in this solution is that when the shift lever 32 moves out to extract the timepiece mechanism 2 to release the jack on the firing component, the contact between the insertion cylinder 33 and the jack of the timepiece mechanism 2 for releasing the firing component is utilized to ensure that when the timepiece mechanism 2 rotates the firing component to the stop position, the connecting effect of the insertion cylinder 33 and the insertion strip 34 can realize the smooth rotation of the rotating frame 6. Moreover, when the timepiece mechanism 2 rotates the firing component to the stop position, the shift lever 32 is aligned with the position of the jack on the timepiece mechanism 2 for releasing the firing component.

[0047] On the top edge of the outer wall on the other side of the rotating frame 6, a sliding seat 14 is also inserted horizontally through a spring rod 27. A diagonal pull rod 38 and a support rod 37 are respectively rotatably connected to the side surface of the sliding seat 14 and the top edge of the outer wall on the other side of the rotating frame 6. One side of the swinging edge of the support rod 37 is hinged to the swinging edge of the diagonal pull rod 38, and on the other side of the swinging edge, a traction plate 36 is hinged between the support rod 37 and the shift lever 32. At the end on the other side of the rotating frame 6, a spring rod 27 is also installed, and an inclined block 42 misaligned with the rack frame 44 is inserted through the spring rod 27 on the inner side wall. On the other side of the sliding seat 14, a fixed shaft 12 fixedly connected to the inclined block 42 and sliding on the inclined surface of the inclined block 42 is provided:

[0048] The significance of this solution is to control the smooth extraction of the shift lever 32 after the timepiece mechanism 2 rotates the firing component to the starting position. The specific method is as follows: By using the contact between the fixed shaft 12 and the inclined surface of the inclined block 42, when the inclined block 42 moves towards the rotating frame 6 against the pulling force of the spring rod 27 at the top edge position, it will force the fixed shaft 12 to drive the sliding seat 14 to move away from the timepiece mechanism 2 against the elastic force of the spring rod 27. During the movement, by using the rotation of the diagonal pull rod 38 and the support rod 37, the support rod 37 is realized to swing away from the timepiece mechanism 2. When the support rod 37 swings away from the timepiece mechanism 2, under the traction of the traction plate 36, the shift lever 32 will be pulled away from the timepiece mechanism 2, that is, the shift lever 32 is disengaged from the jack on the timepiece mechanism 2 for releasing the firing component.

[0049] The bottom edge of the inclined block 42 extends outwards and is respectively rotatably connected to a steering arm 41 and an adjusting arm 30 at the bottom edge position of the rack frame 44. A fulcrum shaft 16 for serving as the fulcrum of the steering arm 41 is fixedly connected to the side of the rack frame 44. The planes where the steering arm 41 and the adjusting arm 30 rotate are arranged in parallel, and a steering rod 40 is also rotatably connected to the swinging end of the steering arm 41. A connecting seat 31 is simultaneously hinged to the swinging edges of the steering rod 40 and the adjusting arm 30. The connecting seat 31 slides along the length direction of the rack frame 44 or swings within the plane parallel to the plane where the adjusting arm 30 rotates;

[0050] As Figure 9As shown in the figure, the present invention can choose to drive the rack frame 44 to lift by installing an electric telescopic rod 7 on the other side of the rotating frame 6, so as to realize the rotation of the gear 45 engaged and connected. In addition, at the connection between the steering arm 41 and the inclined block 42 of this solution, it can be achieved that the steering arm 41 remains perpendicular to the extended part of the inclined block 42 without external force by installing a volute spring. The significance of setting this solution is as follows: As Figure 9 In the state shown in the figure, the set steering arm 30 is parallel to the rack frame 44. Therefore, when the connecting seat 31 descends at this time, the rack frame 44 will be driven to descend under the driving action of the steering arm 30, and the rotation of the gear 45 can be realized. When the steering arm 30 descends, by using the rotational connections of the steering rod 40 with the steering arm 41 and the connecting seat 31, and the rotational connection of the steering arm 41 with the downward extended part of the inclined block 42, the steering rod 40 and the steering arm 41 will rotate and swing away from the fulcrum shaft 16 against the elastic force of the volute spring, that is, to ensure that the inclined block 42 will not change. On the contrary, when the connecting seat 31 swings towards the fulcrum shaft 16 within a certain angle range, it will drive the steering arm 30 to rotate and swing relative to the rack frame 44, and the steering rod 40 will push the swing point of the steering arm 41 upward. However, due to the limiting effect of the fulcrum shaft 16, the steering arm 41 will rotate with the fulcrum shaft 16 as the fulcrum, that is, drive the inclined block 42 to descend by the other side of the steering arm 41:

[0051] Additional explanation, Figure 9 In the state shown in the figure, the dial rod 32 is inserted into the jack for releasing the firing assembly of the clock mechanism 2, but it is the starting position when the clock mechanism 2 releases the firing assembly without rotating, and there is no acting force between the steering arm 41 and the fulcrum shaft 16 at this time. Therefore, after driving the rack frame 44 to descend through the steering arm 30 to realize the rotation of the gear 45, and then realizing the rotation of the clock mechanism 2 to the starting position of the releasing firing assembly, there is a certain distance between the set steering arm 41 and the fulcrum shaft 16. In addition, the electric telescopic rod 7 used to drive the rack frame 44 to descend is a telescopic rod without self-locking function, that is, after the clock mechanism 2 releases the firing assembly and rotates to the starting position, the electric telescopic rod 7 used to drive the rack frame 44 to descend is powered off. Therefore, after the dial rod 32 disengages from the jack on the clock mechanism 2 for releasing the firing assembly, there will be no additional acting force interference when the clock mechanism 2 releases the firing assembly and drives the rack frame 44 to rise and reset.

[0052] On the inner wall of the other side of the rotating frame 6, a motor 47 is inserted. The main shaft of the motor 47 is fixedly connected with an L-shaped plate 48. On the other side of the rotating frame 6, an extension frame strip 35 is also fixedly connected. The frame part of the extension frame strip 35 is arranged parallel to the side surface of the rotating frame 6, and a sliding block 39 is clamped on the inner wall. A collar 43 is rotatably connected to the side surface of the sliding block 39. An electric telescopic rod 7 with a telescopic end passing through the bottom surface of the L-shaped plate 48 and the telescopic end fixedly connected to the surface of the connecting seat 31 is arranged through the collar 43. An electric telescopic rod 7 is also installed on the rotating frame 6 and is used to drive the motor 47 to slide:

[0053] The significance of setting up this scheme is that: in actual use, the auxiliary effect of the L-shaped plate 48 on the main shaft of the motor 47 is used to achieve the stability of the position of the electric telescopic rod 7 in the collar 43. When in use, the electric telescopic rod 7 installed on the rotating frame 6 is contracted to realize the motor 47 to drive the L-shaped plate 48 to descend, and the interference between the L-shaped plate 48 and the connecting seat 31 is used to realize the connecting seat 31 drives the adjustment arm 30 and the rack frame 44 to descend. In addition, the significance of setting up the motor 47 is that the L-shaped plate 48 is driven to rotate by the motor 47 to rotate, so that the L-shaped plate 48 can drive the electric telescopic rod 7 at the corresponding position and the connecting seat 31 connected thereto to rotate and swing in the direction of the fulcrum shaft 16, and the extended frame bar 35 can ensure that the position of the sliding block 39 is relatively The electric telescopic rod 7 of the embodiment of the present invention is stable, and the position of the sleeve 43 is stabilized by stabilizing the position of the sliding block 39, thereby achieving the position stability of the cylinder body of the electric telescopic rod 7 in the scheme, and when the electric telescopic rod 7 of the scheme rotates, the sleeve 43 is connected with the sliding block 39 by rotation, and the sliding block 39 is connected with the extension frame bar 35 by sliding. At the same time, the sleeve 43 rotates relative to the sliding block 39 and slides on the cylinder body of the electric telescopic rod 7. At the same time, the sliding block 39 slides in the extension frame bar 35. In addition, the electric telescopic rod 7 in the sleeve 43 is extended, and when the connecting seat 31 drives the electric telescopic rod 7 at the corresponding position to extend and moves relative to the sleeve 43, the electric telescopic rod 7 on the connecting seat 31 is prevented from being separated from the sleeve 43.

[0054] Embodiment 4: A clamping plate 29 is fixedly connected to one side of the rack frame 44 away from the rotating frame 6. The digital electric stopwatch 3 is provided with two positive electrodes in parallel. The two positive electrodes are respectively used to be provided at the release and firing assembly in the clock mechanism 2 and the clamping plate 29. The digital electric stopwatch 3 is also electrically connected to a negative electrode matching the positive electrode at the clamping plate 29. The two positive electrodes of the digital electric stopwatch 3 are respectively installed at the clamping plate 29 and the starting position of the release and firing assembly in the clock mechanism 2. When actually used, Figure 1 , Figure 10 and Figure 9As shown, at this time, the release and firing component in the clock mechanism 2 is in the stop position, and the release and firing component in the clock mechanism 2 is not in contact with the corresponding positive electrode. However, the positive electrode on the clamping plate 29 is in contact with the corresponding negative electrode. That is, at this time, the digital electric stopwatch 3 is in the circuit-on state. But during the process of the rack frame 44 sliding and the release and firing component in the clock mechanism 2 rotating to the starting position, the positive electrode and the negative electrode on the clamping plate 29 are not in contact. After the release and firing component in the clock mechanism 2 rotates to the starting position, the release and firing component in the clock mechanism 2 clamps the positive electrode at the corresponding position to realize the circuit connection of the digital electric stopwatch 3. That is, it is ensured that the two positive electrodes are not connected simultaneously. By moving the inclined block 42, the sliding seat 14 is moved to make the toggle lever 32 disengage from the jack of the release and firing component of the clock mechanism 2, that is, to realize the release and firing component of the clock mechanism 2 rotating and swinging towards the stop position. At the moment when the release and firing component in the clock mechanism 2 rotates and resets, the positive electrode at the release and firing component in the clock mechanism 2 is powered off, the circuit is not connected, and the digital electric stopwatch 3 starts timing synchronously until the release and firing component of the clock mechanism 2 moves to the stop position. After the release and firing component in the clock mechanism 2 rotates to the stop position, the clamping plate 29 rises and resets so that the positive electrode at this place is in contact with the negative electrode at the corresponding position, realizing the circuit connection of the digital electric stopwatch 3, and the digital electric stopwatch 3 stops timing synchronously. The delay time of the clock mechanism is read from the digital electric stopwatch 3.

[0055] Usage method and working principle of this device: Install the clock mechanism 2 on the experimental bench 1 and clamp and fix it using the clamping mechanism. Combine the two positive electrodes and two negative electrodes of the digital electric stopwatch 3 and install them respectively at the starting positions of the release and firing assembly in the clamping plate 29 and the clock mechanism 2. One set of positive and negative electrodes is installed at the starting position of the release and firing assembly of the clock mechanism 2 and on the release and firing assembly itself respectively, and the other set of positive and negative electrodes is installed at the positions corresponding to the clamping plate 29 on the clamping plate 29 and the rotating frame 6. Use the electric push rod 4 on the support frame 26 to extend and push the rotating frame 6 towards the clock mechanism 2 until the dial rod 32 is inserted into the jack of the release and firing assembly in the clock mechanism 2 and the insert bar 34 is located at the center of rotation of the release and firing assembly in the clock mechanism 2. Use the electric telescopic rod 7 installed on the rotating frame 6 to extend to cause the rack frame 44 to descend, enabling the gear 45 to drive the transmission shaft 46 and the rotating frame 6 to rotate, and further enabling the dial rod 32 and the insert bar 34 to drive the release and firing assembly in the clock mechanism 2 to rotate to the starting position. After rotating to the starting position, the release and firing assembly in the clock mechanism 2 clamps the positive electrode at the corresponding position, and the positive electrode on the clamping plate 29 is connected as the rack frame 44 moves. Then, rotate the connecting seat 31 towards the fulcrum shaft 16 until the steering arm 41 rotates to contact the fulcrum shaft 16. Continuously rotate the connecting seat 31, and the steering arm 41 will rotate with the fulcrum shaft 16 as the fulcrum, that is, drive the inclined block 42 to descend through the other side of the steering arm 41, and further enable the sliding block 39 to move to make the dial rod 32 disengage from the jack of the release and firing assembly in the clock mechanism 2, thus enabling the release and firing assembly in the clock mechanism 2 to drive the insert cylinder 33, the insert bar 34, the rotating frame 6, and the gear 45 to rotate and reset, and further enabling the rack frame 44 to rise and reset. And at the same time when the release and firing assembly in the clock mechanism 2 rotates to the stop position, the positive electrode of the clamping plate 29 is connected. The specific calculation method is as follows: At the moment when the release and firing assembly in the clock mechanism 2 rotates and resets, the positive electrode at the release and firing assembly in the clock mechanism 2 is powered off, the circuit is not connected, and the digital electric stopwatch 3 starts timing synchronously until the release and firing assembly of the clock mechanism 2 moves to the stop position. After the release and firing assembly in the clock mechanism 2 rotates to the stop position, the clamping plate 29 rises and resets until the positive electrode at this position contacts the negative electrode at the corresponding position, enabling the circuit of the digital electric stopwatch 3 to be connected, and the digital electric stopwatch 3 stops timing synchronously. Read the delay time of the clock mechanism from the digital electric stopwatch 3.
