Description

Technical Field

[0001] This invention belongs to the field of gunpowder and explosives technology, and relates to electrical testing, specifically to a fixed mounting tray and system for measuring the resistance of an electric ignition device. Background Technology

[0002] With the advancement of modern industrial technology, technologies such as human-machine isolation, remote control, production process automation, visual control, and remote data acquisition and analysis have become essential, and this is also the future trend of pharmaceutical product production. In existing resistance testing processes for electric igniters, the lack of a dedicated mounting device means that the igniter must be manually fixed and powered on for testing. This manual method is prone to accidents during the power-on testing process. Therefore, existing technologies have the drawback of lacking dedicated fixed equipment for measuring the resistance of electric igniters, failing to meet the requirements of automated operation, and increasing the risk of worker injuries. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a fixed mounting tray for measuring the resistance of electric igniters, thereby solving the technical problem that the lack of dedicated fixed equipment in the process of measuring the resistance of electric igniters in the existing technology makes it easy for workers to have personal injury accidents.

[0004] Another objective of this invention is to provide an electric ignition resistance measurement system that solves the technical problem that the existing electric ignition resistance measurement process cannot achieve automated power-on resistance testing.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0010] The head of a conductor is fixedly installed on the outer side of the clamping lower arm. The head of the conductor is electrically connected to the conductive plate through a flexible conductive element. The conductor is installed on the outer side of the clamping lower arm and passes through the fixing seat and the disassembly seat in sequence. The tail end of the conductor is electrically connected to the conductive contact plate set at the bottom of the mounting countersunk hole. A detachable electrode connector is installed in the mounting countersunk hole. The bottom of the electrode connector can make close contact with the conductive contact plate to achieve electrical connection.

[0045] Example 1:

[0046] This embodiment provides a fixed mounting tray, such as Figure 1 As shown, the device includes a disc body 201, which has one or more parallel-arranged mounting slots 202 for electric ignition devices to be tested. The disc body 201 also has parallel-arranged wire mounting slots 203, with each mounting slot 202 having two corresponding wire mounting slots 203. A fixing device 204 for the electric ignition device to be tested is installed in the mounting slot 202, and a wire fixing device 205 is installed in the wire mounting slot 203.

[0047] like Figure 2 As shown, the electric ignition fixture fixing device 204 to be tested includes a fixing buffer 20401 installed at the bottom of the electric ignition fixture mounting groove 202 to be tested, and the fixing buffer 20401 has an electric ignition fixture mounting cavity 20402 to be tested; the edge of the electric ignition fixture mounting groove 20401 to be tested is foldably fitted with the tail end of a clamping cover 20403.

[0048] like Figure 3 As shown, the wire fixing device 205 includes two wire clamps 20501. Each wire clamp 20501 includes an upper clamping arm 20502 and a lower clamping arm 20503 that are mounted together by a torsion spring. A conductive plate 20504 is fixedly installed on the inner side of the head of the lower clamping arm 20503. The inner sides of the heads of the upper clamping arm 20502 and the lower clamping arm 20503 are closed together to clamp the wire 6. The conductive plate 20504 can contact the wire 6 to conduct electricity.

[0049] like Figure 3As shown, the tail of the clamping lower arm 20503 is fixedly installed at the head end of the fixing seat 20505. The fixing seat 20505 is fixedly installed at the bottom of the wire mounting groove 203. The top of the tail of the fixing seat 20505 is detachably installed with a disassembly seat 20506. The disassembly seat 20506 has a mounting countersunk hole 20507.

[0050] like Figure 3 As shown, the head of a conductor 20512 is fixedly installed on the outer side of the head of the clamping lower arm 20503. The head of the conductor 20512 is electrically connected to the conductive plate 20504 through a flexible conductive element 20508. The conductor 20512 is installed on the outer side of the clamping lower arm 20503. The conductor 20512 passes through the fixing seat 20505 and the disassembly seat 20506 in sequence. The tail end of the conductor 20512 is electrically connected to the conductive contact plate 20509 located at the bottom of the mounting countersunk hole 20507. A detachable electrode connector 206 is installed in the mounting countersunk hole 20507. The bottom of the electrode connector 206 can make close contact with the conductive contact plate 20509 to achieve electrical connection.

[0051] As a preferred embodiment of this invention, such as Figure 2 As shown, the depth of the mounting groove 202 for the electric ignition device to be tested is greater than the depth of the wire mounting groove 203. In this embodiment, preferably, as... Figure 1 As shown, the disc body 201 has 12 parallel electric ignition device mounting slots 202 and 24 parallel wire mounting slots 203.

[0052] As a preferred embodiment of this invention, such as Figure 2 As shown, the clamping cover 20403 includes a cover body 2040301, and a clamping buffer 2040302 is provided on the inner wall of the cover body 2040301. The clamping buffer 2040302 has a conical stepped structure, which ensures the connection area between it and the cover body 2040301, improves the connection strength, and the top of the cone clamps the electric igniter 5 to be tested, increasing the size, increasing the deformation, increasing the clamping force, and improving the installation stability of the electric igniter 5 to be tested.

[0053] As a preferred embodiment of this invention, such as Figure 2 As shown, a buffer clamping member 20510 is provided on the inner side of the head of the clamping upper arm 20502, and a support buffer member 20511 is provided between the inner side of the head of the clamping lower arm 20503 and the conductive plate 20504. The wire 6 is clamped between the buffer clamping member 20510 and the conductive plate 20504.

[0054] As a preferred embodiment of this invention, such as Figure 1As shown, the two sides of the head end of the clamping cap 20403 can be snapped onto both sides of the mounting slot 202 of the electric ignition device to be tested. The snapping of the clamping cap 20403 can further fix the electric ignition device 5 to be tested, ensuring its stability.

[0055] Example 2:

[0056] This embodiment provides an electrode device, such as... Figure 4 As shown, the electrode device 4 includes an electrode connecting frame 401, an electrode adjustment mechanism 402 is mounted on the electrode connecting frame 401, and a resistance measuring electrode 403 is mounted on the electrode adjustment mechanism 402.

[0057] like Figure 5 As shown, the electrode adjustment mechanism 402 includes an upper adjustment unit 40201 and a lower adjustment unit 40202; the upper adjustment unit 40201 and the lower adjustment unit 40202 are supported and connected by a compression buffer spring 40203. The lower end of the lower adjustment unit 40202 is connected to a resistance measuring electrode 403. The resistance measuring electrode 403 is connected to the adjustment rod 4020104 of the upper adjustment unit 40201 by a flexible electrical conductive component 404, so that the resistance measuring electrode 403 is electrically connected to the adjustment head 4020107 of the upper adjustment unit 40201.

[0058] like Figure 5 As shown, the electrode mounting bracket 401 has a through electrode mounting countersunk hole 40104 vertically formed on the support plate 40101. The bottom of the electrode mounting countersunk hole 40104 has an electrode extension hole 40105 that extends through the bottom of the support plate 40101. The upper adjustment unit 40201, the lower adjustment unit 40202, the compression buffer spring 40203, and the resistance measuring electrode 403 are installed in the electrode mounting countersunk hole 40104. The top end of the upper adjustment unit 40201 extends to the top of the electrode mounting countersunk hole 40104, and the bottom end of the resistance measuring electrode 403 extends to the bottom of the electrode mounting countersunk hole 40104 through the electrode extension hole 40105.

[0059] In this embodiment, the design of the conductive connection between the adjusting rod 4020104 and the adjusting head 4020107 and the resistance measuring electrode 403 can meet the requirements of live measurement of the equipment and avoid too many connected parts, which would affect the accuracy of the measurement.

[0060] In this embodiment, the electrode adjustment mechanism 402 is raised and lowered and slid by the electrode connecting frame 401, so as to realize the automated and batch measurement of the resistance of multiple electric ignition devices 5 to be tested at one time, thereby improving the degree of automation and reducing the dependence on measurement personnel.

[0061] In this embodiment, the initial force of the compression buffer spring 40203 can be adjusted differently by adjusting the upper adjustment unit 40201 to meet different compression requirements.

[0062] The above-described structural design in this embodiment ensures that during automated measurement, damage to the resistance measuring electrode 403 is avoided due to installation errors of the electric igniter 5 to be tested, or even defects such as inability to measure due to improper installation.

[0063] As a preferred embodiment of this invention, such as Figure 5 As shown, the electrode connection frame 401 includes a horizontally arranged support plate 40101; the support plate 40101 is fixed to one side of a vertically arranged fixing plate 40102; a plurality of horizontally arranged connecting plates 40103 are fixedly connected to the other side of the fixing plate 40102, and the connecting plates 40103 are vertically provided with connecting holes 40106.

[0064] As a preferred embodiment of this invention, such as Figure 5 As shown, the upper adjustment unit 40201 includes a support body 4020101 vertically installed on the upper part of the electrode mounting countersunk hole 40104. The upper part of the support body 4020101 extends to the top of the electrode mounting countersunk hole 40104. The top of the support body 4020101 is coaxially and vertically provided with an upper adjustment thread countersunk hole 4020102. The bottom of the upper adjustment thread countersunk hole 4020102 is coaxially and vertically provided with an adjustment rod cavity 4020103 that passes through the support body 4020101. The inner diameter of the upper adjustment thread countersunk hole 4020102 is larger than the inner diameter of the adjustment rod cavity 4020103.

[0065] like Figure 5 As shown, an adjusting rod 4020104 is installed inside the adjusting rod cavity 4020103. An upper sliding head 4020105 is installed on the end of the adjusting rod 4020104 that extends out of the bottom end of the adjusting rod 4020103. The upper sliding head 4020105 is located inside the electrode mounting countersunk hole 40104. The end of the adjusting rod 4020104 that extends out of the top end of the adjusting rod cavity 4020103 is fixedly connected to the bottom end of the external thread step 4020106. An adjusting head 4020107 is integrally provided on the top of the external thread step 4020106. The external thread step 4020106 and the upper adjusting thread countersunk hole 4020102 are installed through threaded engagement. Rotating the adjusting head 4020107 adjusts the extension amount of the adjusting rod 4020104.

[0066] The upper adjustment unit 40201 in this embodiment is designed to adjust the initial clamping force of the clamping buffer spring 40203, so as to meet the different rebound force requirements of the resistance measuring electrode 403 under different usage requirements.

[0067] In this embodiment, the upper end of the upper adjustment unit 40201 is connected to the port of an external resistance meter for measuring resistance values. Furthermore, the adjustment head 4020107 is also connected to the port of an external resistance meter for measuring resistance values.

[0068] In this embodiment, the upper adjustment unit 40201 is used to adjust the clamping force and to facilitate connection with an external resistance meter.

[0069] In this embodiment, the lower end of the adjusting rod 4020104 is interference-fitted into the fixing hole of the upper sliding head 4020105.

[0070] As a preferred embodiment of this invention, such as Figure 5 As shown, the lower adjustment unit 40202 includes a lower sliding head 4020201 installed in the electrode mounting countersunk hole 40104. The lower sliding head 4020201 can move up and down in the electrode mounting countersunk hole 40104. The top of the lower sliding head 4020201 is provided with a mounting limiting square countersunk hole 4020202. A telescopic square head 4020203 is embedded in the mounting limiting square countersunk hole 4020202. The telescopic square head 4020203 can move vertically and telescopically in the mounting limiting square countersunk hole 4020202, and the telescopic square head 4020203 can drive the lower sliding head 4020201 to rotate.

[0071] like Figure 5 As shown, the bottom of the mounting limiting square countersunk hole 4020202 is coaxially provided with an electrode telescopic hole 4020204 that passes through the sliding head 4020201. The bottom of the telescopic square head 4020203 is equipped with the top end of the resistance measuring electrode 403. The bottom end of the resistance measuring electrode 403 extends out through the electrode telescopic hole 4020204 and the electrode extension hole 40105 to the bottom of the support plate 40101.

[0072] In this embodiment, the lower adjustment unit 40202 is used to adjust the extension of the resistance measuring electrode 403, and can also provide sufficient buffer margin for the resistance measuring electrode 403 during the measurement process to avoid damage to the resistance measuring electrode 403.

[0073] As a preferred embodiment of this invention, such as Figure 5 As shown, the telescopic square head 4020203 is a regular hexagonal prism or regular octagonal prism structure. This structural design facilitates the rotation of the sliding head 4020201 driven by the telescopic square head 4020203, allowing adjustment of the position of the sliding head 4020201 within the electrode mounting countersunk hole 40104, thereby adjusting the initial extension distance of the resistance measuring electrode 403. It also ensures that during the buffering telescopic process, the telescopic square head 4020203 smoothly enters the mounting limiting countersunk hole 4020202 of the sliding head 4020201.

[0074] As a preferred embodiment of this invention, such as Figure 5 As shown, the top end of the compression buffer spring 40203 is connected to the bottom end of the upper sliding head 4020105, and the bottom end of the compression buffer spring 40203 is connected to the top end of the telescopic square head 4020203. The compression buffer spring 40203 provides a clamping force to the resistance measuring electrode 403, while also allowing for a certain buffering margin.

[0075] As a preferred embodiment of this invention, such as Figure 5 As shown, the outer wall of the sliding head 4020201 has an adjusting external thread, and the inner wall of the electrode mounting countersunk hole 40104 has an adjusting internal thread. The sliding head 4020201 is installed inside the electrode mounting countersunk hole 40104 via the thread, and the height of the sliding head 4020201 inside the electrode mounting countersunk hole 40104 can be adjusted up and down. This structural design in this embodiment ensures that after adjusting the position of the sliding head 4020201, it is in a fixed position, meeting the requirements for use.

[0076] In this embodiment, the resistance measuring electrode 403 drives the telescopic square head 4020203 to move the sliding head 4020201 up and down along the electrode mounting countersunk hole 40104. Because the threaded connection has a self-locking function, after reaching the set position, the sliding head 4020201 is in a relatively fixed position.

[0077] As a preferred embodiment of this invention, such as Figure 5 As shown, multiple sets of electrode adjustment mechanisms 402 are arranged in parallel on the electrode connection frame 401, and each set of electrode adjustment mechanisms 402 includes two electrode adjustment mechanisms 402.

[0078] In this embodiment, since the number of electric igniters that generally need to be measured is not large, and the number of electric igniters 5 to be tested that are fixedly installed at one time is also not large, it is sufficient to use two electrode adjustment mechanisms 402 to measure the resistance of one electric igniter 5 at a time. This reduces the number of electrode adjustment mechanisms 402 and lowers the cost.

[0079] Example 3:

[0080] This embodiment provides a resistance measurement system for electric ignition devices, such as... Figure 6 As shown, it includes a support platform 1, a fixed mounting tray 2 placed on the support platform 1, an electrode three-dimensional moving frame 3 mounted on the support platform 1, an electrode device 4 mounted on the electrode three-dimensional moving frame 3, and the electrode three-dimensional moving frame 3 drives the electrode device 4 to move in three-dimensional direction.

[0081] The above-described structural design in this embodiment improves work efficiency and meets the requirement of installing and measuring multiple electric ignition devices 5 to be tested at one time.

[0082] As a preferred embodiment, the fixed mounting tray 2 adopts the fixed mounting tray given in embodiment 1, and the electric igniter 5 to be tested and the wire 6 of the electric igniter 5 to be tested are fixedly installed in the fixed mounting tray 2.

[0083] As a preferred embodiment of this invention, such as Figure 6 As shown, the electrode three-dimensional moving frame 3 includes a pair of longitudinal guide rails 301 arranged parallel to each other along the longitudinal direction. A transverse guide rail 303 is mounted on the pair of longitudinal guide rails 301 via a pair of longitudinal motion drivers 302. A vertical lifting frame 305 is mounted on the transverse guide rail 303 via a transverse motion driver 304. An electrode device 4 is mounted on the lifting rod 306 inside the vertical lifting frame 305.

[0084] As a preferred embodiment, the electrode device 4 adopts the electrode device given in Embodiment 2.

[0085] Furthermore, the connecting plate 40103 in the electrode connecting frame 401 of the electrode device 4 is fixedly connected to the lifting rod 306 in the vertical lifting frame 305 of the electrode three-dimensional moving frame 3 through the connecting hole 40106.

[0086] As a preferred embodiment of this invention, such as Figure 6 As shown, a lamp holder 7 is mounted on the top of the support platform 1. The lamp holder 7 is a rail-type lamp holder, allowing the lamps to move along the rails on the lamp holder 7. Casters are provided at the bottom of the support platform 1 for easy movement.

[0087] The usage process of the electric ignition resistance measurement system in this embodiment is as follows:

[0088] Place the fixed mounting tray 2 on the top working surface of the support platform 1, place the electric igniter 5 to be tested in the mounting cavity 20402 of the electric igniter to be tested, and press it in place with the clamping cover 20403. Connect the two wires 6 to the head of a wire clamping clamp 20501 respectively. The wires 6 are connected to the electrode connector 206 in sequence through the conductive plate 20504, the flexible conductive element 20508, the conductor 20512, and the conductive contact plate 20509 to achieve electrical conduction.

[0089] The connecting plate 40103 in the electrode connecting frame 401 of the electrode device 4 is fixedly connected to the lifting rod 306 in the vertical lifting frame 305 of the electrode three-dimensional moving frame 3 through the connecting hole 40106, so that the electrode device 4 can move in three-dimensional space under the drive of the electrode three-dimensional moving frame 3.
