Description

Technical Field

[0001] The utility model relates to the technical field of dispensing nozzle processing, in particular to a dispensing nozzle glue outlet processing fixture and a dispensing nozzle processing device. Background Art

[0002] Glue dispensing nozzles are primarily used in dispensing machines, which precisely dispense and apply glue to crafts. Dispensing nozzles are small, typically with an outer diameter of 4mm. High machining precision is required, especially for the concentricity between the center dispensing port and the outer diameter, which in some cases must be within 0.01mm. Therefore, machining dispensing nozzles requires extremely high fixture precision.

[0003] The conventional clamping method is to use a vise. However, in actual use, it was found that because the two clamping parts of the vise are in line contact with the dispensing nozzle, the dispensing nozzle easily tilts within the jaws during clamping, making it difficult to ensure vertical clamping. Inconsistent clamping force each time also leads to different product positions, resulting in excessive concentricity between the dispensing nozzle's outlet and the outer circle. Furthermore, the vise clamping method also suffers from low processing efficiency. Utility Model Content

Multiple positioning grooves 11 can be provided on the base 1, and each positioning groove 11 can accommodate one glue-dispensing nozzle 4. This design facilitates the simultaneous processing of multiple glue-dispensing nozzles 4 and is conducive to improving processing efficiency.

[0027] The positioning groove 11 has a first positioning surface 111 and a second positioning surface 112. The first positioning surface 111 and the second positioning surface 112 are arranged in a V shape, and both the first positioning surface 111 and the second positioning surface 112 are used to contact the outer peripheral surface of the glue-dispensing nozzle 4 to position the glue-dispensing nozzle 4 in a direction perpendicular to the axial direction of the glue-dispensing nozzle 4. Specifically, the first positioning surface 111 and the second positioning surface 112 can be flat surfaces and form the groove walls of the positioning groove 11.

[0028] Please refer to Figure 3 , The pushing device 2 includes a main body 21 and a push rod 22. The main body 21 is fixed to the base 1, and the push rod 22 can move relative to the main body 21 and has a first position and a second position. Specifically, a chamber can be provided in the main body 21 of the pushing device 2, and the push rod 22 is slidably assembled in the chamber. The driving method of the pushing device 2 can be electric, such as an electric telescopic rod, or hydraulic drive, such as a micro oil cylinder. When the push rod 22 of the pushing device 2 extends, the push rod 22 is in the first position; when the push rod 22 retracts, the push rod 22 is in the second position.

[0029] In the first position, the push rod 22 abuts against the glue-dispensing nozzle 4 and makes the glue-dispensing nozzle 4 abut against the first positioning surface 111 and the second positioning surface 112 to achieve the positioning and clamping of the glue-dispensing nozzle 4. The first positioning surface 111 and the second positioning surface 112 can be pre-processed vertical surfaces, which can position the glue-dispensing nozzle 4 and make the glue-dispensing nozzle 4 in a vertical state. At the same time, due to the existence of the pushing device 2, the glue-dispensing nozzle 4 will not tilt away from the positioning surface. In the second position, the push rod 22 of the pushing device 2 is separated from the glue-dispensing nozzle 4, which is convenient for replacing a new glue-dispensing nozzle 4 for processing and is conducive to improving processing efficiency.

[0032] In some embodiments, please refer to Figure 2 and Figure 3 , a pushing portion 221 is provided at one end of the push rod 22 away from the main body 21. In the first position, there is a point contact between the pushing portion 221 and the outer peripheral surface of the dispensing nozzle 4. If the pushing portion 221 is set as a flat surface, in order to achieve the vertical positioning of the dispensing nozzle 4, it is necessary to ensure that the flat surface of the pushing portion 221 has good parallelism with the positioning surface, which requires high machining and assembly accuracy for the pushing device 2. By adopting the point contact method, the machining and assembly accuracy requirements for the pushing device 2 can be reduced.
