Example 1

[0028] In order to solve the technical problems in the background technology, the following ceramic ignition needle needle extension length measuring device is provided:

[0029] Combine Figures 1-6As shown, the ceramic ignition needle needle extension length measuring device provided by the present invention includes a base 1, a mounting cover 2 is fixedly installed on the top of the base 1, a loading seat 5 is rotatably installed on the top of the mounting cover 2, a loading assembly 3 installed and connected to the loading seat 5 is assembled inside the mounting cover 2, placement holes 51 are evenly distributed on the top of the loading seat 5, a unloading assembly 8 is fixedly installed on the outside of the loading seat 5, a column 4 is fixedly installed on one side of the top of the base 1, a docking assembly 6 is fixedly installed on the front of the column 4, and a measuring assembly 7 corresponding to the docking assembly 6 is assembled on the top of the column 4;

[0030] During this period, the orderly corresponding placement of the ignition needles is achieved through the placement holes 51, and the loading assembly 3 in the installation cover 2 can drive the loading seat 5 to rotate and lift, so that the ignition needle to be measured can be placed and loaded, and the ignition needle is sent to the detection state by lifting, and the personnel can insert and place the ignition needle to ensure the convenience of the overall operation. The unloading assembly 8 can not only ensure the detection operation of the ignition needle, but also can quickly unload after the detection is completed. Through the mutual cooperation between the docking assembly 6 and the measuring assembly 7, the device can not only be adjusted in real time according to the actual size of the ignition needle, but also realize the separation between the needle head and the needle body. At the same time, the elongation of the ignition needle needle head can be measured by mutual docking using infrared rays.

[0031] The docking assembly 6 includes a first docking plate 61, a second docking plate 62, a mounting seat 63, a threaded adjustment knob 64, and an infrared receiver 65. The mounting seat 63 is fixedly installed on the front of the column 4, and the infrared receiver 65 is embedded in the top of the mounting seat 63. The front of the mounting seat 63 is provided with a mounting port 631. The inside of the mounting port 631 is docked with the first docking plate 61 and the second docking plate 62 through the threaded adjustment knob 64. The first docking plate 61 and the second docking plate 62 are provided with corresponding needle docking ports 611; the measuring assembly 7 includes a second cylinder 71, a contact detection component 72, an infrared Transmitter 75, a second cylinder 71 is docked and installed on the top of the column 4, and a resistance detection component 72 is docked and installed on the output end of the second cylinder 71, and the resistance detection component 72 corresponds to the first docking plate 61 and the second docking plate 62. An infrared transmitter 75 corresponding to the infrared receiver 65 is embedded in the bottom of the resistance detection component 72; the unloading assembly 8 includes a third cylinder 81, a mounting bracket 82, and a material blocking plug plate 83. The mounting bracket 82 is fixedly installed on the bottom of the outer side of the loading seat 5, and the third cylinder 81 is fixedly installed on the mounting bracket 82.

The personnel first adjusts the first docking plate 61 and the second docking plate 62 relative to each other through the threaded adjustment knob 64, so as to adjust the distance between the needle docking interface 611 in real time to ensure that the measured needle can be normally inserted. As the ignition needle is lifted up, the ignition needle will pass through the needle docking interface 611, and the separation between the needle body and the needle is achieved through the first docking plate 61 and the second docking plate 62. Then the second cylinder 71 drives the contact detection component 72 to move downward. The contact detection component 72 is pressed down to the top of the ignition needle.

At this time, the ignition needle can be unloaded from the bottom of the placement hole 51. Example 2

[0033] like Figure 1 and Figure 6 As shown, based on the above embodiment, this embodiment further provides the following content:

[0034] In this embodiment, the loading assembly 3 includes a motor 31, a support plate 32, and a first cylinder 33. Two groups of first cylinders 33 are fixedly installed inside the mounting cover 2.

The motor 31 is fixedly installed on the top of the support plate 32, and the output end of the motor 31 is installed and connected to the loading seat 5.

[0035] When the ignition needle is placed in the placement hole 51, the person can start the motor 31, and the output shaft of the motor 31 drives the loading seat 5 to rotate, prompting the loading seat 5 to switch to the working position;

[0036] Then start the first cylinder 33, the first cylinder 33 will push the support plate 32, prompting the loading seat 5 to be lifted, prompting the needle head of the ignition needle in the loading seat 5 to penetrate the docking plate and enter the measuring state.

[0037] In this embodiment, the measuring component 7 also includes a connecting block 73 and a guide rod 74. An installation chamber 41 is provided on the back of the column 4. The output end of the second cylinder 71 extends into the installation chamber 41, and the output end is docked with the connecting block 73. A guide rod 74 passing through the connecting block 73 is docked with the installation chamber 41. A guide port 42 connected to the installation chamber 41 is provided on the front of the column 4. The connecting block 73 extends out of the guide port 42 and is installed and connected to the contact detection component 72.

[0038] When measuring, the operator can start the second cylinder 71, and the second cylinder 71 pushes the connecting block 73, which drives the contact-type detection component 72 to descend.

[0039] The connecting block 73 completes the conduction of the resistance type detection component 72 through the guide opening 42 , and completes the stable pushing of the resistance type detection component 72 in cooperation with the guide rod 74 , prompting the resistance type detection component 72 to be pressed downward.

[0042] By combining the above contents, the rubber pad 725 and the mounting plate 726 at the bottom of the mounting cavity 721 are pressed down, and the rubber pad 725 will first hit the needle. After being under pressure, the limit joint 724 on the mounting plate 726 will be pushed up in the mounting tube 722. At that time, the lower electrical contact 727 on the limit joint 724 is completed and docked with the upper electrical contact 728. The infrared receiver 65 and the infrared transmitter 75 are powered on and started to perform infrared ranging operations to achieve the measurement of the elongation of the needle. The infrared emission and infrared reception are set based on the infrared ranging sensor LDM301.

[0043] After the pressure is lost, the lower electrical contact 727 and the upper electrical contact 728 are separated under the force of the spring 729 .

[0044] In this embodiment, the first docking plate 61 and the second docking plate 62 are staggered with each other, and the thread adjustment knob 64 has opposing threads.

[0045] Before taking measurements, personnel first make real-time adjustments based on the actual size of the needle. By offsetting the first docking plate 61 and the second docking plate 62, the mounting opening 631 between the first docking plate 61 and the second docking plate 62 can be adjusted to ensure the penetration of the needle and to block the needle body. The first docking plate 61 and the second docking plate 62 are adjusted by rotating the threaded adjustment knob 64 to promote relative movement between the first docking plate 61 and the second docking plate 62.

[0047] The plug interface and the placement hole 51 correspond to each other;

[0048] The blocking plate 83 can complete the plugging and blocking of the placement hole 51 under external force, and the measuring needle can then be placed in the placement hole 51 to prevent it from falling. When the blocking plate 83 is separated from the placement hole 51, the needle body falls.
