The nozzle 101 is inserted into one end of the nozzle 102, the fixing member 103 is sleeved on the nozzle 102, and the fixing member 103 is used for moving on the nozzle 102 and being fastened in place. Wherein the fixing member 103 comprises a collar and a locking mechanism. The collar is movably disposed on the nozzle 102, and the locking mechanism may be a fastening bolt or the like for fixedly securing the collar on the nozzle 102.
As shown in fig. 2 to 4, the present invention provides a nozzle length adjusting apparatus, which may generally include an adjusting stage 1, an end aligning unit 2, a fixing frame 3, an adjusting unit 4, and a scale 5. The adjusting table 1 is a flat plate or table structure, and the end aligning unit 2, the fixing frame 3, the adjusting unit 4 and the scale 5 are all installed on the adjusting table 1. The adjustment table 1 is provided with an alignment point. When the end portion aligning unit 2 is mounted, the testing end thereof is located above the alignment point to monitor whether the end portion of the head 101 of the nozzle 100 is located at the alignment point (or located above the alignment point, i.e., the projected point of the end portion of the head 101 is located at the alignment point). The fixing frame 3 is mounted on the adjusting table 1 through a first moving platform, so that the fixing frame 3 can move on the adjusting table 1. The holder 3 is used to hold and fix the nozzle 100. After the nozzle 100 is fixedly clamped on the fixed frame 3, the position of the fixed frame 3 on the adjusting table 1 can be adjusted through the first moving platform, so that the position of the nozzle 100 is adjusted, the end part of the spray head 101 of the nozzle 100 is adjusted, and the end part of the spray head 101 is positioned at the alignment point or above the alignment point. The fixing frame 3 is provided with a fixing plate 31. The nozzle 100 can be clamped and fixed by the fixing plate 31 and the fastening bolt. The adjusting unit 4 is mounted on the adjusting table 1 through a second moving platform. The adjustment unit 4 is provided with a snap-in portion 41. The engaging portion 41 has a convex portion protruding from the surface of the adjusting unit 4, and the convex portion can engage with the fixing member 103 of the nozzle 100 and be interlocked with the fixing member 103, that is, the fixing member 103 moves synchronously with the adjusting unit 4. So that the fixing member 103 is moved in the axial direction of the nozzle 102 of the nozzle 100 by the catching portion 41 when the position of the adjusting unit 4 is moved by the second moving platform. One end (i.e., the 0-scale line) of the scale 5 is aligned with the alignment point, and the other end extends toward the click portion 41. After the nozzle 100 is fixed to the holder 3, the longitudinal direction of the nozzle 100 is parallel to the direction of the scale 5.
When in use, the nozzle 100 is firstly fixed on the fixing frame 3, and the fixing part 103 of the nozzle 100 is positioned on the adjusting unit 4; then, the position of the fixing frame 3 is adjusted through the movable platform, so that the position of the end part of one end of the spray head 101 is adjusted; in the adjusting process, the end part aligning unit 2 is used for monitoring whether the end part of one end of the spray head 101 is positioned at an aligning point in real time; when the end part of one end of the nozzle 101 is aligned with the alignment point, the position of the adjusting unit 4 is adjusted by the movable platform until the scale corresponding to the clamping portion 41 is required to be long, and the fixing member 103 is screwed down. By the nozzle length adjusting device, the length of the manufactured nozzle 100 (namely the length L from the end part of the spray head 101 to the fixing part 103) is consistent, so that the nozzle can be used without re-adjustment after being directly installed on equipment, and the problems of poor precision and complex operation of re-adjustment after installation are solved.
Specifically, as shown in fig. 2-4, in one particular embodiment, the end alignment unit 2 includes a calibration plate 21 and a calibration device 22. The calibration plate 21 is fixedly mounted on the adjustment table 1 with the alignment point located in the center of the calibration plate 21. The calibration unit of the calibration device 22 is mounted above the calibration plate 21. The user can clearly observe whether the end of the spray head 101 is located at the alignment point through the calibration means 22.
The calibration plate 21 is provided with XY-axis coordinates perpendicular to each other, and the alignment point is an XY-axis intersection (i.e., origin of coordinates). Optionally, the calibration device 22 is a camera. Preferably, the camera is a CCD camera. The CCD camera has the advantages of wide application and low cost. Whether one end of the nozzle 101 is located at the alignment point can be conveniently monitored by the camera and recorded in real time. The lens of the camera is located right above the intersection point of the XY axes, and one end of the head 101 of the camera monitoring nozzle 100 through photographing is located at a position on the calibration plate 21. When the end point of the one end of the nozzle 101 is located at the alignment point (or directly above the alignment point), the end point of the one end of the nozzle 101 can be observed to coincide with the alignment point through the image taken by the camera.
In a preferred embodiment, a display terminal (not shown) is also included. The display terminal is in signal connection with the calibration device 22 to receive the monitoring signal of the calibration device 22, and displays the position of one end of the nozzle 101 of the nozzle 100 on the calibration plate 21 in real time. As shown in fig. 6, the display condition of the end position of the nozzle 101 is displayed through the display terminal, and the monitoring process can be conveniently amplified and displayed through the display terminal, and recorded, so as to facilitate the adjustment and alignment.
In other embodiments, the calibration device 22 may also be a light emitting device (e.g., laser emitter, flashlight) that emits a linear beam-shaped light beam, with the calibration device 22 being positioned directly above the alignment point. During monitoring, the light-emitting device emits a light beam toward the calibration plate 21. By observing the projected point of the end of the head 101 of the nozzle 100 on the calibration plate 21, it can be determined whether the end of the head 101 is located at the alignment point.
It should be understood that the end aligning unit 2 may be selected as needed by those skilled in the art, and is intended to conveniently monitor and judge whether the end of the head 101 is located at the aligning point, so that the 0-th scale line of the scale 5 is aligned with the end of the head 101.
The snap-in part 41 of the adjustment unit 4 is provided with a marking 42 facing the scale 5, the marking 42 pointing to the scale on the scale 5. When the fixing member 103 is snapped to the snapping portion 41, the identification portion 42 is aligned with the fixing member 103 for identifying the corresponding scale value of the fixing member 103 on the scale 5.
In a specific embodiment, the tip aligning unit 2 and the fixing frame 3 are both mounted on the adjusting table 1 by an XY moving stage 6. The structure of the XY moving stage 6 is shown in fig. 5. The XY moving stage 6 includes a moving stage body 61, an X axial moving caliper 62, and a Y axial moving caliper 63. The X-axis moving caliper 62 is used to mark the moving distance of the XY moving stage 6 along the X-axis direction, and the Y-axis moving caliper 63 is used to mark the moving distance of the XY moving stage 6 along the Y-axis direction. The XY moving stage 6 may be a manual moving stage, an electric moving stage, or the like. The electric moving platform adopts electric drive, hydraulic drive and the like. The manual moving platform can be manually moved by adopting a threaded lead screw and has the advantages of simple structure, self-locking and accurate moving stroke. The X-axis moving caliper 62 and the Y-axis moving caliper 63 of the XY moving stage 6 can accurately display the moving strokes in the X-axis direction and the Y-axis direction, and are convenient to adjust, and the accuracy of the moving calipers can be selected as required. Through the mobile platform with the mobile caliper, the moving distances of the mobile platform on the X axis and the Y axis can be known conveniently, and adjustment is facilitated.
The end aligning unit 2 is mounted on the adjusting table 1 through the XY moving stage 6, so that the position of the end aligning unit 2 can be conveniently adjusted, and the situation that the calibrating device 22 is not positioned above the center of the calibrating plate 21 is avoided.
Of course, a moving platform without a moving caliper may be used. The length of the nozzle 100 is read only in the scale of the scale.
In an alternative embodiment, the adjustment unit 4 is mounted on the adjustment table 1 by means of a linear or XY-moving table 6. Wherein, the moving direction of the linear moving platform is parallel to the length direction of the scale 5; the X direction or the Y direction in the XY moving stage 6 is parallel to the longitudinal direction of the scale 5. The structure of the XY moving stage 6 is the same as described above and will not be described here. The linear motion stage is a stage having a motion in one direction, such as only in the X direction or the Y direction. This is because the adjustment unit 4 only needs to be moved in the longitudinal direction along the scale. The linear moving platform can simplify the whole structure and reduce the cost. Preferably, the linear moving platform is also provided with a corresponding moving caliper for displaying the moving stroke in real time.
The invention also provides a nozzle length adjusting method, which adopts the nozzle length adjusting device to adjust the length from one end of the spray head 101 of the nozzle 100 to the fixing part 103, thereby manufacturing the nozzles 100 with consistent length. The specific structure of the nozzle 100 is shown in fig. 1.

fixedly mounting the nozzle 100 on the fixing frame 3;
the position of the fixing frame 3 is adjusted to enable one end of the spray head 101 of the spray nozzle 100 to be located at an alignment point;
the adjusting unit 4 is adjusted to the marking position of the scale 5 according to the length required by the nozzle 100 by clamping and fixing the clamping part 41 and the fixing part 103;
the fixing member 103 is locked and fixed. By this step, the nozzle 100 having a uniform length and meeting the requirement can be manufactured. The nozzle 100 is then installed on the device and ready for use without the need to recalibrate the length after installation.
Specifically, according to a nozzle length adjusting method of the present invention, when manufacturing the nozzle 100, after inserting the nozzle head 101 into the nozzle tube 102, the alignment point of the center of the alignment device 22 to the adjustment table 1 (or the center of the alignment plate 21) is first adjusted; then the nozzle 100 is fixed on the fixing frame 3; then adjusting the position of the fixing frame 3 to enable one end of the spray head 101 to be located at the alignment point; then adjusting the position of the adjusting unit 4 to make the scale value corresponding to the identification part 42 be the required length value of the nozzle 100; finally, the position of the fixing member 103 is kept unchanged, and the locking mechanism of the fixing member 103 is screwed down, that is, the fixing member 103 is fastened and positioned, so that the nozzle 100 with the length meeting the requirement can be manufactured. The sequential steps can realize the calibration of the length of the nozzle 100 before the nozzle is installed in the equipment, and the problems of accuracy and troublesome calibration after the nozzle is installed are avoided.
According to the nozzle length adjusting device and the adjusting method thereof provided by the invention, the length from one end of the spray head 101 of the nozzle 100 to the fixing part 103 can be adjusted and measured, so that the length of the manufactured nozzle 100 is kept consistent after the fixing part 103 is fastened and positioned, the nozzle 100 can be directly used after being installed on equipment, the length is not required to be adjusted and calibrated after being installed, and the device and the method have the advantages of high precision and convenience in operation.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
