Description

Technical Field

[0001] The invention relates to the field of turning of spray nozzles, in particular to a device capable of performing batch turning of spray nozzles. Background Art

[0002] The spray nozzle is a crucial component in the spraying equipment. It mainly relies on devices such as pressure pumps to make the paint obtain high pressure. When the high-pressure paint passes through the small hole of the nozzle, the cross-sectional area suddenly becomes smaller. According to the Bernoulli principle, the flow rate increases sharply, forming a high-speed jet. After leaving the nozzle, it is dispersed and atomized into fine particles under the action of air resistance and other factors, and is evenly sprayed on the surface of the object.

[0003] At present, the spray nozzles mainly include:

[0004] Fan-shaped nozzle: The spray shape is fan-shaped, the spray channel is large and smooth, which can reduce blockage. There are many types such as narrow angle and wide angle. It can produce high-impact or medium-impact spray, which is suitable for metal processing cleaning, spray coating and other fields;

[0005] Conical nozzle: It is composed of a spiral tube and a conical tip. It can form smaller droplets under high pressure. It is divided into hollow cone and solid cone. Hollow cone nozzle is suitable for occasions that require uniform coverage and do not require high coverage of the central area; solid cone nozzle can provide a more uniform spray in the entire cone area, which is suitable for work that requires comprehensive and uniform spraying.

[0006] Special nozzles: Double fan nozzles can form two fan-shaped spray effects at the same time, which can cover a larger area in one spray process and improve work efficiency. Anti-drift nozzles can reduce drift during the spray process and make the spray fall more accurately on the target area.

[0007] However, no matter what kind of nozzle is used, it generally needs to be turned to produce a specified shape during the specific production process. However, the existing turning equipment generally has a single fixture setting, so that after the turning process of the spray nozzle is completed, the fixture needs to be loosened and tightened again, the processed spray nozzle is removed, and a new blank is replaced for processing. This loosening and tightening process is extremely time-consuming, resulting in a decrease in the efficiency of loading and unloading, and it is impossible to efficiently turn and produce spray nozzles in large quantities. Therefore, a batch turning processing device for spray nozzles is proposed. Summary of the invention

[0008] In order to overcome the shortcomings of the prior art, the present invention proposes a device for batch turning of spray nozzles, which can efficiently and quickly load and unload the spray nozzles during turning, thereby facilitating large-scale batch production.

DETAILED DESCRIPTION

[0036] The following will be combined with the attached Figure 1 To Attachment Fig. 9 The technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] It should be noted that if there are directions involved in the embodiments of the present invention, they shall be based on the directions shown in the drawings, such as front and back. Figure 1 The specific Figure 1 The left side is the front, Figure 1 The right side is the back; at the same time Figure 2 As shown in the figure, the left-right direction is roughly the horizontal direction, and the up-down direction shown in the figure is the vertical direction. If a certain posture changes, the directional indication will also change accordingly.

[0038] Embodiment 1:

[0039] like Figure 1-5 As shown, the present invention discloses a batch turning processing device for spray nozzles, comprising a chassis 1, a turning module 2 is installed on one side of the chassis 1, and a gear ring 4 is rotatably installed on the chassis 1, and a support 5 is connected to the gear ring 4, and both sides of the support 5 are penetrated by a sleeve with an I-shaped cylinder 6, and one side of the I-shaped cylinder 6 is axially slidably connected with a chuck 8, and a clamping groove 10 is provided on the chuck 8, and both sides of the I-shaped cylinder 6 are slidably connected with a concave frame 14, and a clamping claw 16 is bolted on the concave frame 14, and a rotating rod 15 is rotatably connected between the chuck 8 and each concave frame 14, wherein the turning module 2 is the part of the existing lathe that includes the turning tool, and this technology is the existing technology and will not be repeated, and at the same time, the bolt installation of the clamping claw 16 and the concave frame 14 can conveniently replace different models of the clamping claw 16 in different usage scenarios, so as to facilitate the clamping processing of spray nozzles of various specifications and sizes;

[0040] A card frame 17 is connected inside the chassis 1, and slides 18 are slidably connected to both sides of the card frame 17. A baffle 20 for contacting the chuck 8 is connected to one slide 18, a rack 31 is connected to the slide 18, and a transmission gear 19 meshing with the rack 31 is rotatably connected to the card frame 17. A driving component 1 is provided on the other slide 18, and the driving component 1 is used to drive the chuck 8 corresponding to the other slide 18 to rotate by cooperating with the card slot 10. A driving component 2 is provided on the chassis 1, and the driving component 2 is used to drive the gear ring 4 to rotate.

[0041] A guide slide bar 7 is connected to the I-shaped cylinder 6, and a chuck 8 is slidably sleeved on the outer side of the guide slide bar 7. A spring 9 is sleeved on the outer side of the guide slide bar 7 between the chuck 8 and the I-shaped cylinder 6. The guide slide bar 7 enables the chuck 8 to slide stably on one side of the I-shaped cylinder 6, and the setting of the spring 9 enables the chuck 8 to slide toward the side of the I-shaped cylinder 6 without the action of external force.

[0042] The front and rear sides of the I-shaped cylinder 6 are connected with guide rails 12 in an array, and a sliding frame 13 is sleeved on the outer side of the guide rails 12. The two ends of the concave frame 14 are bolted to the sliding frames 13 on the front and rear sides of the I-shaped cylinder 6 respectively. One end of the rotating rod 15 is rotatably connected to the chuck 8, and the other end is rotatably connected to the sliding frame 13. The arrangement of the guide rails 12 and the sliding frame 13 can stabilize the sliding of the concave frame 14. At the same time, the concave frame 14 is also mounted on the sliding frame 13 by bolts. In this way, when the model of some spray nozzles changes, the position of the concave frame 14 on the sliding frame 13 can be adjusted by removing the bolts. When this adjustment cannot meet the use needs, the claws 16 can also be replaced, which greatly improves the versatility of the device.

[0043] The slides 18 on both sides of the card frame 17 are respectively located at the two ends of the card frame 17 away from each other, and the racks 31 are connected at both ends of each card frame 17. Both sides of the card frame 17 are rotatably connected with the transmission gears 19. The transmission gears 19 are located between the racks 31 on the card frames 17 on both sides and are meshed with the racks 31 on both sides. In this way, when the slide 18 on one side slides, the slide 18 on the other side will slide in the opposite direction under the meshing connection between the racks 31 and the transmission gears 19.

[0044] The front end of the chassis 1 is provided with a second circular hole 28, in which the chuck 8 and the baffle 20 both slide and pass, and the setting of the second circular hole 28 facilitates the baffle 20 to be adjusted to a state flush with the front side of the chassis 1 or to be retracted into the chassis 1. When retracted into the chassis 1, the corresponding chuck 8 will move forward under the action of the spring 9 because there is no limit on the baffle 20, and drive each slide frame 13, the concave frame 14 and the claw 16 to move away from each other, so as to facilitate the unloading of the completed spray nozzle blank and the reloading of the spray nozzle blank, and will not affect the turning of the spray nozzle blank clamped on the other side of the I-shaped cylinder 6, which can save the time of unloading and loading, and is convenient for large-scale and efficient production. The design of the right sides cooperating with each other and operating independently, in specific processing and production, the I-shaped cylinders 6 on both sides can also adjust the position of the concave frame 14 on the slide frame 13 or replace different claws 16, and simultaneously alternately mass-produce spray nozzles of two specifications and sizes.

[0045] A side of the chuck 8 close to the chassis 1 is rotatably connected to a plurality of balls 11 in an array, and the balls 11 are rollingly connected to the surface of the chassis 1 or the surface of the baffle 20. The arrangement of the balls 11 can transform the sliding movement of the chuck 8 on the baffle 20 or the chassis 1 into rolling movement, thereby reducing wear and improving durability.

[0046] Embodiment 2:

[0047] like Figure 1-9 As shown, the present invention discloses a device for batch turning of spray nozzles. Compared with the first embodiment, the present embodiment discloses the structure of a driving component.

[0048] The driving assembly 1 includes a motor 1 21, a sleeve 22, a disc 23, and the motor 1 21 is connected to the slide 18. The output end of the motor 1 21 is connected to the sleeve 22. The disc 23 is slidably sleeved in the sleeve 22. A spring 25 is connected between one end of the disc 23 and the inner wall of the sleeve 22, and a key 24 is connected to the other end. The key 24 passes through the sleeve 22 and extends outside the sleeve 22, and cooperates with the corresponding card slot 10. A telescopic member 26 is connected between the motor 1 21 and the inner wall of the chassis 1, so that the telescopic member can be used to The extension of 26 drives the slide plate 18 and the motor 1 21 card key 24 on this side to move forward. The card key 24 may be misaligned with the card slot 10 at first. At this time, the card key 24 is partially compressed into the sleeve 22. Driven by the motor 1 21, when the card key 24 and the card slot 10 are aligned, the two are engaged with each other under the elastic force of the spring 25. At this time, the operation of the motor 1 21 can drive the chuck 8, the I-shaped cylinder 6, the claw 16 and the spray nozzle blank clamped on the claw 16 to rotate, and cooperate with the turning module 2 to perform turning processing;

[0049] At the same time in the above process, due to the cooperation between the rack 31 and the transmission gear 19, the slide plate 18 on the other side will drive the baffle 20 to move backward, eliminating the interference between the baffle 20 and the chuck 8 on the other side, and then the processed spray nozzle blank clamped in the I-shaped cylinder 6 on the other side can be removed and replaced with a new one for processing.

[0050] An opening is provided at one end of the sleeve 22 to cooperate with the key 24. The key 24 slides through the opening and cooperates with the opening to limit the position. A circular hole 27 is provided on the chassis 1. The key 24 and the sleeve 22 slide in the circular hole 27. The diameter of the circular hole 27 is smaller than the diameter of the chuck 8. The design of the opening can prevent the key 24 and the sleeve 22 from rotating relative to each other, and the design of the circular hole 27 facilitates the passage of the key 24 and the sleeve 22. At the same time, the diameter of the circular hole 27 is smaller than the diameter of the chuck 8. Therefore, the chuck 8 on the I-shaped cylinder 6 in the turning state can stably contact the front side of the chassis 1, thereby realizing the clamping of the sprayed blank by the claws 16.

[0051] A support plate 3 is installed on the chassis 1, and the card frame 17 and the telescopic member 26 are both installed on the support plate 3, which facilitates the installation of related structural equipment.

[0052] Embodiment three:

[0053] like Figure 1-9 As shown, the present invention discloses a device for batch turning of spray nozzles. Compared with the second embodiment, this embodiment discloses the structure of the second driving component.

[0054] The driving component 2 includes a motor 29 and a driving gear 30. The motor 29 is installed on the chassis 1. The driving gear 30 is connected to the output end of the motor 29 and is meshed with the gear ring 4. The operation of the motor 29 can drive the gear ring 4 to rotate, and drive the support 5 to rotate to adjust the position of the I-shaped cylinder 6 on both sides, so as to ensure that the spray nozzle clamped in the I-shaped cylinder 6 on the side corresponding to the turning module 2 can be efficiently in a turning processing state, while the other side can be loaded and unloaded, which greatly improves the efficiency of the turning processing of the spray nozzle and is suitable for large-scale processing and production.

[0055] According to the disclosure and teaching of the above description, those skilled in the art to which the present invention belongs may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the present invention.
