[0036] The technical solution of the present utility model will be further described below in conjunction with the drawings and through specific implementation modes.

[0037] As Figures 2 - 4As shown in the figure, this embodiment provides a detection device for a nozzle. The nozzle includes a nozzle seat 1 and a tip 2 disposed within the nozzle seat 1. A preset installation gap is provided between the circumferential direction of the tip 2 and the nozzle seat 1. The detection device for this nozzle includes a detection seat 100, a magnification assembly 200, and a reference plate 300. The detection seat 100 is provided with a fixture assembly 110 for fixing the nozzle seat 1. The magnification assembly 200 includes a connector 210 and a magnification pointer 220. The magnification pointer 220 is disposed at one end of the connector 210. The other end of the connector 210 is connected to the tip 2 and is spaced apart from the nozzle seat 1. The reference plate 300 is disposed on the detection seat 100 and is located at the end of the magnification pointer 220 away from the connector 210. The reference plate 300 is used to measure the displacement of the magnification pointer 220 in at least two planes.

[0038] By providing the detection seat 100, it is used to integrate the magnification assembly 200 and the reference plate 300. At the same time, the fixture assembly 110 on the detection seat 100 is used to fix the nozzle seat 1 of the nozzle. The magnification assembly 200 is used to magnify the preset installation gap for the inspector to observe. One end of the connector 210 is used to connect the tip 2 and is spaced apart from the nozzle seat 1, so that when the connector 210 is shaken, the tip 2 will shake relative to the nozzle seat 1. Since the other end of the connector 210 is provided with a magnification pointer 220, the magnification pointer 220 can magnify the shake of the tip 2 relative to the nozzle seat 1. The inspector can judge whether the preset installation gap meets the requirements by observing the magnification pointer 220 with a larger shake amount. In addition, a reference plate 300 is also provided on the detection seat 100 at the end of the magnification pointer 220 away from the connector 210, which is used to provide a reference for the shake amount of the magnification pointer 220. At the same time, the reference plate 300 can measure the displacement of the magnification pointer 220 in at least two planes, that is, the detection device can detect the preset installation gap at different angles, improving the reliability of the detection result.

[0039] Exemplarily, at least two reference plates 300 are provided. The base plates are disposed on the detection seat 100 through columns, and at least two reference plates 300 are disposed at the end of the magnification pointer 220 away from the connector 210, and adjacent two reference plates 300 are disposed at an angle. It can be understood that a protractor is provided on each reference plate 300 to display the shake angle of the magnification pointer 220 in this plane.

[0040] Optionally, the reference plate 300 is provided in a horn shape and is disposed to surround the end of the magnification pointer 220 away from the connector 210. The horn-shaped reference plate 300 can provide a reference for the shake of the magnification pointer 220 within 360°, making the detection structure of the nozzle more accurate. It is worth noting that the horn-shaped reference plate 300 can reflect the shake angle of the magnification pointer 220 through the gap with the magnification pointer 220, thereby assisting the inspector to judge whether the preset installation gap meets the requirements.

[0041] Specifically, as Figure 3 shown, the connector 210 includes a base 211 and a connecting sleeve 212. The magnifying pointer 220 is disposed at one end of the base 211. A plurality of connecting posts are provided at the other end of the base 211. The tip 2 can be placed between the plurality of connecting posts. The connecting sleeve 212 is threadedly connected to the outside of the plurality of connecting posts. When installing the nozzle and the connector 210, the tip 2 of the nozzle is inserted into the plurality of connecting posts, and then the connecting sleeve 212 is screwed to make the plurality of connecting posts approach each other to fix the tip 2. It should be noted that after the nozzle is fixed, the end of the connecting sleeve 212 away from the base 211 is spaced from the nozzle seat 1, which facilitates interference between the connecting sleeve 212 and the nozzle seat 1 during subsequent detection of shaking.

[0042] Furthermore, an installation hole is provided at the end of the base 211 away from the connecting sleeve 212. The magnifying pointer 220 is detachably disposed in the installation hole. The detachably disposed magnifying pointer 220 facilitates storage when the detection device is not in use. At the same time, different-diameter magnifying pointers 220 can be replaced. The smaller the diameter of the magnifying pointer 220, the higher the detection accuracy, which improves the versatility of the detection device.

[0043] Optionally, a set screw hole 213 is provided through the side wall of the installation hole. The set screw can be placed in the set screw hole 213 and abuts against the magnifying pointer 220 to connect the magnifying pointer 220 and the base 211. Preferably, a placement groove 120 is provided on the detection base 100. The placement groove 120 is used to place the magnifying pointer 220 that is not connected to the base 211.

[0044] In other embodiments, the magnifying pointer 220 is also provided to be integrally provided with the connector 210, which reduces the operation process and improves the detection efficiency.

[0045] As an alternative solution of the detection device, as Figure 4 shown, the fixture assembly 110 includes a fixture base 111 and a locking member. A clamping groove 112 is provided on the fixture base 111, and the inner diameter of the clamping groove 112 is adjustable. When installing the nozzle, the nozzle seat 1 is placed in the clamping groove 112, and then the locking member is adjusted so that the inner diameter of the clamping groove 112 is reduced to fit the nozzle seat 1 to clamp the nozzle seat 1.

[0046] In this embodiment, two clamping arms 113 are provided at intervals on the fixture base 111. Grooves 114 are provided on the sides of the clamping arms 113 close to each other. The two grooves 114 form the clamping groove 112. The locking member adjusts the distance between the two clamping arms 113 to adjust the inner diameter of the clamping groove 112. At the same time, the locking member fixes the relative movement of the two clamping arms 113 to stably clamp the nozzle seat 1 by the two clamping arms 113.

[0047] Specifically, the locking member includes a locking bolt. Among the two clamping arms 113, one is provided with a locking through hole, and the other is provided with a locking threaded hole. The locking bolt can pass through the locking through hole and be threadedly connected to the locking threaded hole. After the nozzle is placed in the clamping groove 112, the locking bolt is screwed to make the two clamping arms 113 approach each other and clamp the nozzle seat 1. The locking bolt can also be locked while being adjusted, with a simpler structure and more convenient operation. Preferably, a handle can also be provided on the locking bolt to further facilitate the operation of the operator.

[0048] The use process of the above detection device is as follows: First, install the magnifying pointer 220 on the seat body 211 and fix it with a setscrew; insert the tip 2 into the seat body 211, leaving a gap, and screw the connecting sleeve 212 to connect the tip 2 and the seat body 211, so that the nozzle seat 1 and the connecting sleeve 212 are spaced apart; place the nozzle seat 1 in the clamping groove 112 and lock it with the locking member; push the connecting head 210 and observe the movement of the magnifying pointer 220 to further determine whether the preset installation gap meets the requirements.

[0049] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present invention.
