[0065] Figure 1 The structure of the test equipment for the cartridge case primer in the present application is shown in the figure Figure 1 , Figure 2 The structure of the test equipment for the cartridge case primer in the present application is shown in the figure Figure 2 , for example Figure 1 and Figure 2As shown, the device comprises a rotating mechanism 10, a feeding mechanism 20 and a firing mechanism 30, wherein the rotating mechanism 10 has a rotating disc 101 and a driving structure (not shown in the figure), a plurality of positioning structures 102 for carrying and positioning the cartridge case with primer are arranged along the circumferential direction of the rotating disc 101, and the driving structure is connected with the rotating disc 101 for driving the rotating disc 101 to rotate so that the plurality of positioning structures 102 rotate around the center of the rotating disc 101. For example, the driving structure can drive the rotating disc 101 to rotate counterclockwise.

[0066] In an implementation, the positioning structure 102 can be a positioning hole, the inner wall of which can be provided with a limiting structure, or the upper diameter of the positioning hole is larger than the lower diameter, so as to prevent the cartridge case from falling when the cartridge case is loaded into the positioning structure 102.

[0067] The feeding mechanism 20 is arranged on one side of the rotating mechanism 10, and is used for loading the cartridge case with primer into the positioning structure 102 when at least one positioning structure 102 rotates to a first position corresponding to the feeding mechanism 20.

[0068] The firing mechanism 30 is arranged on one side of the rotating mechanism 10, and is used for striking the primer of the cartridge case in the positioning structure 102 to obtain the test data of the primer of the cartridge case when at least one positioning structure 102 rotates to a second position corresponding to the firing mechanism 30.

[0069] The cartridge case primer testing device provided by the present application can not only greatly save the labor cost, but also improve the test efficiency of the cartridge case primer.

[0070] As shown in the figure, Figure 1 The feeding mechanism 20 in the present application can comprise a carrying structure 201 and a loading structure 202: wherein the carrying structure 201 is used for carrying the cartridge case with primer and making the cartridge case orderly pass through a feeding opening and fall into the loading structure 202; the first end of the loading structure 202 is connected with the feeding opening of the carrying structure 201, and the second end is located above the rotating disc 101, and is used for loading the cartridge case into the positioning structure 102 when the positioning structure 102 rotates to a first position corresponding to the loading structure 202.

[0071] Here, the specific composition of the carrying structure 201 is not limited, and can be a centrifugal disc (such as Figure 1The vibration hopper can also be the centrifugal disc and the vibration hopper. By taking the centrifugal disc and the vibration hopper as the bearing structure, the loaded shell can be vibrated to achieve the effect of sorting the shells, so that the shell blockage caused by a large number of shells entering the material inlet can be avoided, and the shell loading efficiency and the test efficiency can be further improved.

[0072] In the present application, the test device further comprises a detection mechanism 40 arranged on one side of the rotating mechanism 10, used for detecting the loading depth of the primer in the shell in the positioning structure 102 when at least one of the positioning structures 102 rotates to the third position corresponding to the detection mechanism 40. The loading depth of the primer hit by the firing mechanism meets the target condition.

[0073] Here, the detection mechanism 40 can detect the loading depth of the primer in the shell in the positioning structure 102 by a contact method (such as infrared detection and laser detection); or by a non-contact method (such as probe detection).

[0074] When the detection mechanism 40 detects the loading depth of the primer by a contact method, the detection mechanism 40 can include a first movement module 401 and a displacement sensor 402, wherein the first movement module 401 is connected with the displacement sensor 402, used for driving the displacement sensor 402 to move to adjust the distance between the displacement sensor 402 and the primer in the positioning structure 102 when at least one of the positioning structures 102 rotates to the third position corresponding to the displacement sensor 402; and the displacement sensor 402 is arranged on the first movement module 401, used for detecting the loading depth of the primer in the shell in the positioning structure 102.

[0075] In one implementation, the first movement module 401 can be a chain movement or a lead screw movement. The first movement module 401 can include a slide rail, a motor, a first probe and a second probe. The first probe and the second probe are arranged adjacent to each other on the slide rail and are driven by the motor to move up and down on the slide rail, thereby driving the first probe and the second probe to move up and down. The displacement sensor is arranged at the free end of the first probe and the second probe. When the free end of the first probe contacts the shell, the first probe stops moving. When the free end of the second probe contacts the primer in the shell, the second probe stops moving. Since the depth of the shell is known, the loading depth of the primer in the shell can be obtained by calculating the distance between the free end of the first probe and the free end of the second probe.

[0076] In the present application, the device further comprises a rejection mechanism 50 for rejecting the cartridge from the corresponding positioning structure when the loading depth of the cartridge primer meets the rejection condition.

[0077] Here, the specific structure of the rejection mechanism 50 is not limited, which can be an upper ejector cylinder arranged at the bottom of the rotating disc 101, extending into the positioning structure 102 from the bottom of the positioning structure 102 to eject the cartridge from the positioning structure 102; or a lower pressing cylinder arranged at the top of the rotating disc 101, extending into the positioning structure 102 from the top of the positioning structure 102 to eject the cartridge in the positioning structure 102; or a clamp arranged above the rotating disc 101, which ejects the cartridge in the positioning structure 102 to a preset height by the upper ejector cylinder at the bottom of the rotating disc 101, and then clamps the ejected cartridge from above the rotating disc 101 by the clamp.

[0078] Here, when the depth error between the loading depth of the cartridge primer and the preset loading depth is greater than the preset threshold, it is determined that the loading depth of the cartridge primer meets the rejection condition.

[0079] In the present application, the device further comprises a recovery mechanism 60 for recovering the cartridge after being hit when the positioning structure 102 rotates to the fourth position corresponding to the recovery mechanism 60.

[0080] Here, the recovery mechanism 60 comprises a plurality of recovery channels 601, each recovery channel 601 corresponding to a recovery pool 602, and each recovery pool 602 recovering cartridges with different firing states or properties.

[0081] Here, the inlet position of the recovery channel 601 is not limited, which can be arranged below the rotating disc 101 or above the rotating disc 101. When the inlet of the recovery channel 601 is arranged below the rotating disc 101, the inlet of the recovery channel 601 can be arranged with an opening and closing structure (not shown in the figure), which, when corresponding to the positioning structure 102, can make the cartridge in the positioning structure 102 fall into the corresponding recovery pool 602 through the corresponding recovery channel 601 by controlling the opening and closing structure of the inlet of the recovery channel 601. When the inlet of the recovery channel 601 is arranged above the rotating disc (as shown in the figure), the cartridge in the corresponding positioning structure 102 can be ejected into the inlet of the recovery channel 601 by the upper ejector cylinder arranged below the rotating disc 101, so that the ejected cartridge falls into the corresponding recovery pool 602 through the corresponding recovery channel 601. Figure 1

[0082] In the present application, the recovery mechanism 60 can further comprise a counter (not shown in the figure) connected to each of the recovery pools 602 for counting the number of cartridges in each of the recovery pools 602.

[0083] ​The test equipment of the shell primer provided by the application can greatly save labor cost and improve test efficiency, and by detecting the loading depth of the primer in the shell and removing unqualified shells, the test accuracy of the shell primer can be greatly improved.

[0084] As shown in Figure 1 and Figure 2 The firing mechanism 30 can include a second movement module 301, a firing assembly 302 and a sensor (not shown in the figure); wherein the second movement module 301 is connected with the firing assembly 302, and is used to drive the firing assembly 302 to move, so as to adjust the distance between the firing assembly 302 and the rotating disc or the positioning structure or the shell primer; the firing assembly 302 is arranged on the second movement module 301, and is used to lower the firing component 3021 from the target position in the case that the positioning structure 102 rotates to the second position corresponding to the firing assembly 302, so as to hit the shell primer in the positioning structure 102 by the firing component 3021. For example, when the sensitivity of the 9mm primer is tested, the protruding amount of the firing component is 1.45mm-1.65mm, and when the sensitivity of the 5.56mm primer is tested, the protruding amount of the firing component is 0.81mm±0.01mm.

[0085] Here, the specific implementation of the second movement module 301 is not limited, which can be realized by a servo motor driving a lead screw to move, or can be realized by a chain to move.

[0086] The sensor is used to detect the firing state of the shell primer, so as to obtain the test data of the shell primer. The sensor can be a sound sensor, which can determine the firing state of the shell primer by detecting the sound signal generated when the shell primer is hit. For example, when the sound signal is within the range of 80-120dB, it is determined that the firing state of the shell primer is normal, and when the sound signal is not within the range of 80-120dB, it is determined that the firing state of the shell primer is abnormal.

[0087] Here, the setting position of the sensor is not limited, as long as it can detect the firing state of the shell primer after the shell primer is hit.

[0088] The application can adjust the height of the firing component through the firing mechanism, which can meet the requirement of hitting the shell primer in a single or multiple positioning structures from different heights, so as to further improve the test accuracy of the shell primer.

[0089] Here, the adjustment range of the firing mechanism to the firing component is 0mm-600mm, which can be set arbitrarily within this interval, and can be indicated by a scale ruler, and the allowable deviation is not more than ±0.10mm, and the repeat positioning accuracy is ±0.02mm.

[0090] IfFigure 1 and Figure 2 As shown, the firing mechanism 30 may further include a third motion module 303 and a reset component 304. The third motion module 303 is connected to the reset component 304, is disposed on one side of the second motion module 301, and moves in the same direction as the second motion module 301. It is used to drive the reset component 304 to move, thereby adjusting the current position of the reset component 304. The reset component 304 is disposed on the third motion module 303, located below the firing component 3021, and is used to reset the firing component 3021 under the action of the third motion module 303 after the firing component 3021 has landed.

[0091] Here, the firing component 3021 can be a firing ball or a firing pin, which can be connected to the firing assembly via magnetic attraction. When the positioning structure 102 rotates to the corresponding position of the firing component 3021, the reset component 304 can move above the positioning structure 102 under the drive of the third motion module 303, so that the cartridge case inside the positioning structure 102 is located at the center of the reset component and protrudes from the upper surface of the reset component 304, so that the firing component 3021 falls and strikes the primer of the cartridge case. After the primer of the cartridge case is struck, the firing component 3021 is located on the reset component 304. The reset component 304 can move upward under the drive of the third motion module 303 to return the firing component 3021 to the firing assembly 302, thereby realizing the reset of the firing component.

[0092] Here, the third motion module can achieve motion through a lead screw or a chain; the specific implementation of the third motion module is not limited here.

[0093] Here, the firing mechanism may also include a magnetization detection structure (not shown in the figure) to prevent the firing component from falling out if the firing component is demagnetized.

[0094] like Figure 1 As shown, the rotating mechanism 10 in this application may further include a fourth motion module 103, which is disposed below the rotating disk 101, and is used to push the cartridge case in the positioning structure 102 out of a preset height when the positioning structure 102 is rotated to the second position corresponding to the firing assembly 302.

[0095] Here, there can be multiple fourth motion modules 103, and multiple fourth motion modules 103 are arranged around the circumference of the rotating disk 101.

[0096] Here, the firing mechanism 30 can further include a clamping structure 305; the clamping structure 305 can be located above the rotating disc 101, and used to clamp and fix the ejected shell in cooperation with the fourth movement module 103 when the positioning structure 102 rotates to the second position corresponding to the firing assembly 302.

[0097] Here, the fourth movement module 103 can be an upper ejector cylinder, and the clamping structure 305 can be a clamping cylinder. Through the cooperation of the fourth movement module 103 and the clamping structure 305, the shell can be fixed, the firing accuracy of the shell primer can be improved, the shell primer can be prevented from deviating, and the situation of firing failure can be avoided.

[0098] As shown in Figure 1 The test device in the present application further includes a base 70 having a bearing surface 701 for bearing the rotating mechanism 10, the feeding mechanism 20, the firing mechanism 30, the recovery mechanism 60, the detection mechanism 40, and the rejection mechanism 50. Here, the flatness of the bearing surface 701 can be 0.03mm / 300mm.

[0099] As shown in Figure 3 The test device in the present application further includes a shell 80 having a receiving cavity (not shown in the figure), and the rotating mechanism 10, the feeding mechanism 20, the firing mechanism 30, the recovery mechanism 60, the detection mechanism 40, and the rejection mechanism 50 are all arranged in the receiving cavity; the shell 80 can protect and prevent dust from entering the rotating mechanism 10, the feeding mechanism 20, the firing mechanism 30, the recovery mechanism 60, the detection mechanism 40, and the rejection mechanism 50.

[0100] Here, the shell 80 can have a door structure, and the opening and closing of the door structure can facilitate the observation of the components or mechanisms in the receiving cavity, and facilitate the loading and use of the shell.

[0101] Here, the shell 80 can further be provided with a data processing mechanism 801 for adjusting the related parameters used in the test of the shell primer. For example, the data processing mechanism 801 can be a computer.

[0102] Here, the test device can further include an output interface 90 for outputting the test data of the shell primer.

[0103] Here, the output interface 90 can be connected with the data processing mechanism 801 or the printing mechanism 802. The output interface 90 can be a display screen, a loudspeaker, or a touch screen of the data processing mechanism, etc. It can also be a display screen of the printing mechanism 802.

[0104] Here, the shell 80 can also be provided with a recycling window 803 corresponding to the position of the recycling pool 602, for taking out the shell sample after being hit from the recycling pool 602 through the recycling window 803.

[0105] Here, the shell can also be provided with a system interface 804 for system regulation and maintenance.

[0106] In this application, the test device also includes a purification interface 100 for connecting with a smoke purifier (not shown in the figure), for purifying the primer smoke generated by the shell through the smoke purifier.

[0107] Here, the setting position of the purification interface 100 is not limited, which can be set on the base 70 or on the shell 80, as long as it can realize the purification of the smoke generated by the shell primer. In this way, the pollution of smoke to the mechanisms and components in the device can be reduced, and the service life of the device can be improved.

[0108] Through the test device for shell primer provided in this application, the firing state of the shell primer can be accurately identified as normal (such as firing) or abnormal (such as misfire), the test accuracy and test efficiency of the shell primer are improved, and the labor cost is greatly reduced.

[0109] Figure 4 The flowchart for the control method in this application is shown, the method is applied to the test device for shell primer described above, and the method includes:

[0110] Step 4001, based on the preset parameter, the current position of the firing assembly is adjusted by the firing mechanism of the test device, so that the firing assembly is located at the target position corresponding to the preset parameter;

[0111] Here, the preset parameter can be set according to the input interface on the test device, which includes but is not limited to voice input interface, touch panel, physical button, etc. By different preset parameters, the firing assembly can be adjusted to different heights, so as to realize the test purpose of the shell primer from different heights.

[0112] Step 4002, if the shell loaded on the test device meets the target condition, the rotating mechanism of the test device is controlled to rotate, so that the shell is rotated to the corresponding position of the firing assembly under the driving of the rotating mechanism;

[0113] Here, the test device can detect the loading depth of the cartridge primer in the cartridge, obtain the loading depth of the cartridge primer, compare the loading depth with the preset depth, and if the comparison result represents that the depth error between the loading depth and the preset depth is greater than or equal to the error threshold, it is determined that the loading depth of the cartridge primer does not meet the target condition, and the cartridge primer that does not meet the target condition is rejected and is not counted as a test sample. If the comparison result represents that the depth error between the loading depth and the preset depth is less than the error threshold, it is determined that the loading depth of the cartridge primer meets the target condition, and the next secondary process of the cartridge primer is performed.

[0114] In another implementation, the test device can also detect whether a cartridge is loaded in the positioning structure of the rotating mechanism when the positioning structure is rotated to the corresponding position of the firing assembly, and if it is detected that the cartridge is loaded in the positioning structure, it is determined that the cartridge meets the target condition.

[0115] Step 4003, controlling the firing assembly to hit the cartridge primer from the target position to obtain test data of the cartridge primer.

[0117] For example, when the sound signal is within the range of 80-120 dB, it is determined that the state information of the cartridge primer is normal firing, and when the sound signal is outside the range of 80-120 dB, it is determined that the state information of the cartridge primer is abnormal firing.

[0118] In this application, the test device can also store the test data of the cartridge primer, so that the staff can view the data at any time and perform data analysis, and can also classify and store the cartridges that have been hit for transportation and use.

[0119] In this application, the test device can also receive a data acquisition instruction for the cartridge primer, and based on the data acquisition instruction, the test data for the cartridge primer can be output.
