Description

Technical Field

[0001] The invention relates to the technical field of metal detonator detection, and in particular to a metal detonator shell performance detection device. Background Art

[0002] Metal detonator is an explosive device commonly used in mining, building demolition and military fields. It mainly consists of a metal shell and an internal explosive charge. When the detonator receives an appropriate excitation signal, the internal charge will burn or explode rapidly, generating enough energy to detonate the main explosive connected to it.

[0003] In order to ensure the safe use of metal detonators, generally after the production of metal detonators is completed, the performance sampling test of the metal detonator shell is also required. This test is an important step for the detonator to work safely and reliably under various environmental conditions. Among them, impact and vibration tests are important links to ensure the quality and safety of detonators. Through strict testing procedures, the risks of detonators in actual applications can be effectively reduced and the reliability and safety of use can be improved.

[0004] The existing impact and vibration testing devices for metal detonators are relatively complex. For the impact test of metal detonators, a pneumatic or hydraulic system is generally used to drive a hammer or other types of impact tools to apply a specified impact energy to the detonator. For the vibration test of the metal detonator, a vibration table is generally used for vibration. The two performance tests are combined. However, the testing process of the existing impact testing device is not comprehensive and accurate enough. It can only impact a single point position of the metal detonator. In actual transportation, the fulcrum of the metal detonator varies greatly. The change of the fulcrum will affect the performance test results of the metal detonator. In addition, the existing impact and vibration testing devices can only test a single metal detonator, and the efficiency of the performance test needs to be improved. Summary of the invention

The turning handle 5714 is limited by tightening the bolt 5712 to generate contact friction with the rubber ring on the outer wall of the rotating ring 53 to prevent the clamping seat 54 from loosening.

[0044] See also Figure 4 The opposite moving part 521 includes a bidirectional screw rod 5211 rotatably connected between the front and rear walls of the mounting seat 2, and a guide rod 5212 fixedly connected between the front and rear walls of the mounting seat 2.

[0045] During specific operation, the motor 5213 is used to control the rotation of the bidirectional screw rod 5211, and the bidirectional screw rod 5211 drives the mounting frame 52 to move forward and backward along the guide rod 5212, so as to meet the requirements of locking the ends of detonators of different lengths.

[0046] See also Figure 1 and Figure 5 The rotating component 2 51 includes a worm wheel 511 fixedly connected to the front position of the front rotating ring 53, and a worm segment 513 is meshedly connected to the lower side of the worm wheel 511.

[0049] During specific operation, when the striking rod 45 hits the detonator, as the rotation speed of the rotating seat 44 increases, the centrifugal force of the weight block 4511 on the striking rod 45 will also increase, and the weight block 4511 moves along the sliding rod 4513 toward the end of the striking rod 45 away from the central axis of the rotating seat 44. The counterweight at the end of the striking rod 45 away from the central axis of the rotating seat 44 will increase. By increasing the weight at the end of the striking rod 45, the striking force of the striking rod 45 is increased, and by disassembling and assembling weighted balls of different weights, the extreme value of the striking force can be changed.

[0050] See also Figure 2 and Figure 3 The rotating assembly 47 includes a bevel gear 471 fixedly connected to the rear end of each pin shaft 441, and the periphery of each bevel gear 471 is meshed with a bevel gear 474, and the center of each bevel gear 474 is fixedly connected to the same coupling shaft 475.

[0051] During specific operation, the motor 2 473 drives the coupling shaft 1 475 to rotate to control the rotation of each bevel gear 2 474, and the rotation of the bevel gear 2 474 drives the bevel gear 1 471 to rotate to control the rotation of the pin shaft 441, so as to control the rotation of the swivel seat 44, so as to achieve the effect of periodic rotation of the striking rod 45 to contact the detonator.

[0052] See also Figure 1 and Figure 2The reciprocating moving component 41 includes a motor 411 fixedly connected to the center of the upper end of the arch frame 22, the output end of the motor 411 rotates through the arch frame 22 and is fixedly connected to a rotating plate 416, a slide groove 415 is provided on the rotating plate 416, a slider 414 is slidably connected in the slide groove 415, the slider 414 is fixedly connected to the output end of the electric push rod 413 on one side close to the central axis of the output end of the motor 411, the electric push rod 413 is fixedly connected to the rotating plate 416, a connecting rod 417 is fixedly connected to the lower side of the slider 414, the lower end of the connecting rod 417 is fixedly connected to a limited guide wheel 418, a limited movable groove 419 is provided on the mounting rod 42, the limited guide wheel 418 is movably connected in the limited movable groove 419, and the left and right sides of the mounting rod 42 are also slidably penetrated by support rods 412, the ends of the left and right support rods 412 are fixedly connected to the vertical plates 21, and the lower ends of each vertical plate 21 are correspondingly fixedly connected to the mounting seat 2.

[0053] During specific operation, the motor 411 drives the rotating plate 416 to rotate, and the rotating plate 416 drives the connecting rod 417 to rotate around the central axis of the output end of the motor 411. The limiting guide wheel 418 on the connecting rod 417 will move along the limiting movable groove 419 to adapt to the displacement of the connecting rod 417 in the left and right directions. The displacement of the connecting rod 417 in the front and back directions will drive the mounting rod 42 to move back and forth along the straight rod, thereby driving the striking rod 45 to move back and forth in the front and back directions, thereby continuously changing the contact position of the striking rod 45 and the detonator in the front and back directions, thereby increasing the striking range on the detonator, and controlling the distance from the rotating rod to the central axis of the output end of the motor 411 through the electric push rod 413 to change the range of the front and back movement of the striking rod 45, thereby satisfying the need for more comprehensive striking of detonators of different lengths.

[0054] See also Figure 3 The left and right sides of the striking rod 45 are also fixedly connected with a second spring 46 , and one end of the second spring 46 away from the striking rod 45 is fixedly connected to the annular wall of the rotating seat 44 .

[0055] During specific operation, two sets of springs 46 are used to elastically support the striking rod 45. After the striking rod 45 contacts the detonator, the spring 46 on one side will retract to make the striking rod 45 tilted, so that the striking rod 45 can pass over the detonator, avoiding the problem of hard contact and interference between the striking rod 45 and the detonator, making it difficult to continue to rotate. After the striking rod 45 passes over the detonator, the springs 46 on both sides restore the striking rod 45 to its original position.

[0056] See also Fig. 9 The abutment seat 54 is a hollow structure, and a plurality of abutment blocks 541 are equidistantly slidably penetrate the side wall of the abutment seat 54 close to the detonator. The movable range of the abutment blocks 541 does not exceed the abutment seat 54, and a plurality of balls 542 are filled between each abutment block 541 and the inner side of the side wall of the abutment seat 54 away from the detonator.

[0057] During specific operation, after the tightening seat 54 contacts the detonator, the resisting block 541 in the middle position will contact the detonator first, and the continued tightening action of the tightening seat 54 will squeeze the ball 542 in the middle position to flow to both sides until all the resisting blocks 541 contact the detonator, and all the resisting blocks 541 and the ball 542 are in a squeezed state, so that each resisting block 541 can fit and contact the detonator, thereby satisfying the fitting and pressing of detonators of different diameters, ensuring sufficient pressing area, and improving the pressing friction effect. After replacing detonators of different diameters, if the diameter is smaller than the previous one, the resisting block 541 in the middle position is also limited to contact, and the subsequent resisting blocks 541 on the side will contact and adapt to the fit. If the diameter is larger than the previous one, the resisting block 541 on the side will contact the detonator first, and continue to apply force. The rollers 542 on the side will be driven to flow to the middle, squeezing out the resisting block 541 in the middle position, until all the resisting blocks 541 are adaptively fitted to the detonator.

[0058] When in use: S1: Place the whole device in the safe house, and then perform the performance test of the detonator. During the test, first, the motor 5213 is used to control the two-way screw rod 5211 to rotate, and the two-way screw rod 5211 drives the mounting frame 52 to move forward and backward along the guide rod 5212, so that the rotating ring 53 can correspond to the end position of the detonator. Then, the handle 5714 is used to control the pin rod 5713 to drive the driving gear 5711 to rotate, and the driving gear 5711 drives the gear ring 5715 to rotate, and the gear ring 5715 controls the annular plate 57 The inclined groove 56 on the annular plate 57 drives the connecting pin 551 to control the movable rod 55 to move radially, and the movable rod 55 drives the tightening seat 54 to tighten the detonator. After the tightening seat 54 contacts the detonator, the middle position of the block 541 will first contact the detonator, and the tightening action of the tightening seat 54 will squeeze the ball 542 in the middle position to flow to both sides until all the blocks 541 contact the detonator. All the blocks 541 and the ball 542 are in a squeezed state, so that each block 541 can fit and contact the detonator.

[0059] S2: After the detonator is locked, start motor 1 411, motor 2 473 and motor 3 512, and the motor 1 411 drives the rotating plate 416 to rotate, and the rotating plate 416 drives the connecting rod 417 to rotate around the central axis of the output end of the motor 1 411. The limiting guide wheel 418 on the connecting rod 417 will move along the limiting movable groove 419 to adapt to the displacement of the connecting rod 417 in the left and right directions. The displacement of the connecting rod 417 in the front and back directions will drive the mounting rod 42 to move back and forth along the straight rod, thereby driving the striking rod 45 to move back and forth in the front and back directions, thereby continuously changing the contact position between the striking rod 45 and the detonator in the front and back directions. When testing detonators of different lengths, the electric push rod 413 is used to control the distance from the rotating rod to the central axis of the output end of the motor 1 411, thereby changing the range of the front and back movement of the striking rod 45.

[0060] S3: While S2 is being carried out, the motor 2 473 drives the coupling shaft 1 475 to rotate and control the rotation of each bevel gear 2 474, and the rotation of the bevel gear 2 474 drives the bevel gear 1 471 to rotate and control the rotation of the pin shaft 441, so as to control the rotation of the rotating seat 44, and the rotating seat 44 drives the striking rod 45 to periodically strike the detonator, and at the same time, the motor 3 512 drives the coupling shaft 2 514 to rotate and control each worm segment 513 to drive each worm wheel 511 to rotate, and the rotation of the worm wheel 511 drives the swivel 53 to rotate on the mounting seat 2, and the swivel 53 drives the locked detonator to rotate, so as to change the circumferential force point of the detonator, and at the same time, the vibration of the vibration motor 32 drives the mounting seat 2 to vibrate, and the spring seat 31 adapts to the vibration of the mounting seat 2 to provide elastic support, and the vibration of the mounting seat 2 drives the detonator to vibrate.

[0061] S4: When the striking force needs to be changed, the speed of the rotating seat 44 is accelerated by increasing the speed of the motor 2 473, and the centrifugal force of the weight block 4511 on the striking rod 45 will also increase, so that the weight block 4511 will move along the sliding rod 4513 toward the end of the striking rod 45 away from the central axis of the rotating seat 44, and the counterweight at the end of the striking rod 45 away from the central axis of the rotating seat 44 will be increased. By increasing the weight at the end of the striking rod 45, the striking force of the striking rod 45 is increased, and by disassembling and assembling weighted balls of different weights, the extreme value of the striking force can be changed.

[0062] S5: After the test is completed, the detonator shell is deformed and the internal structure is loose to determine whether the detonator's impact resistance and vibration resistance meet the requirements.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
