Description

A fixture for a spraying device Technical Field

[0001] This utility model relates to the fields of machining and automation control, specifically a fixing fixture for a spraying device. Background Technology

[0002] In the fields of machining and automation control, spraying devices are widely used in surface processes such as spraying, sandblasting, and chemical treatment. Traditional spraying devices usually adopt a fixed structure, with the spray gun directly installed on the equipment, which lacks flexibility and is easily affected by equipment vibration during operation, resulting in unstable spraying quality.

[0003] The existing spraying device is cumbersome to maintain and adjust after it is fixed, usually requiring complete disassembly, which increases downtime and maintenance costs. During the spraying process, the flow state of the sprayed medium cannot be effectively intervened, and the length of the spray gun is fixed, which cannot be flexibly adjusted according to work requirements, resulting in a limited range of applications. Therefore, we need to propose a fixing fixture for the spraying device. Summary of the Invention

[0004] The purpose of this utility model is to provide a fixing fixture for a spraying device, which improves the stability during operation by changing the fixing method of the spraying device and the environment in which the spray gun is located. At the same time, it changes the working method that requires overall disassembly for maintenance, and the length of the spray gun can be changed according to the working requirements, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fixing fixture for a spraying device includes a protective pipe, a connecting support, a connecting pipe, a connector, a nozzle, and a joint; the connecting support is disposed on the outer wall of the protective pipe, the connecting pipe is inserted into the inside of the protective pipe, and one end of the connecting pipe is connected to the nozzle, the nozzle is located inside the protective pipe, the joint is installed at the other end of the connecting pipe for connecting to compressed air, and the bottom of the joint is connected to a spraying medium pipe for supplying spraying medium.

[0007] Preferably, the connecting support includes a flange and a boss tube. The boss tube is welded to one side of the flange. One end of the protective tube passes through the boss tube and extends to one side of the flange. A first locking screw for limiting the position of the protective tube is threaded on the top of the boss tube. The bottom of the first locking screw abuts against the outer wall of the protective tube.

[0008] Preferably, the flange has a protrusion on the side away from the boss tube, and both the flange and the boss tube are made of stainless steel.

[0009] Preferably, the connector includes a tapered sleeve, an abutment ring, and a locking nut. The tapered sleeve and the abutment ring are both sleeved on the outer wall of the connecting pipe. The outer wall of the tapered sleeve abuts against the inside of one end of the protective pipe. One end of the abutment ring is inserted into the inside of the tapered sleeve, and one side of the abutment ring abuts against the end of the protective pipe. The locking nut is threaded onto the outer wall of the connecting pipe, and one side of the locking nut abuts against one side of the abutment ring.

[0010] Preferably, the outer wall of the connecting pipe is provided with an external thread adapted to the locking nut, and the locking nut is threadedly connected to the external thread.

[0011] Preferably, both the tapered sleeve and the abutment ring are made of elastic rubber material.

[0012] Preferably, a support ring is fixedly installed on the inner wall of the end of the protective tube away from the connector, and one end of the connecting tube passes through the support ring and is fixedly installed with the nozzle.

[0013] Preferably, a protective medium tube for supplying an external protective medium is installed at the bottom of one end of the protective tube, and a second locking screw for auxiliary contact with the connecting tube is threaded on one side of the protective medium tube.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The connecting support of this utility model adopts a structure of flange and boss tube welded together. The protective tube passes through the boss tube and extends to one side of the flange. The protective tube is limited by the first locking screw at the top of the boss tube. This design makes the connection between the protective tube and the connecting support stable, effectively preventing the protective tube from shaking or shifting during operation, ensuring the stability of the overall structure of the spray device. At the same time, by adjusting the first locking screw, the position of the protective tube and its internal nozzle can be adjusted to meet different installation requirements and applicable ranges, and it is also convenient to quickly disassemble and replace related parts.

[0016] 2. Both the tapered sleeve and the abutment ring are made of elastic rubber. The locking nut applies force to the abutment ring, which in turn applies force to the tapered sleeve. This cooperation effectively fills the gap between the connecting pipe and the protective pipe, preventing leakage of compressed air and spray medium, and ensuring the normal operation of the spraying device. The connecting support limits the protective pipe, and the connecting piece tightly connects the connecting pipe and the protective pipe, forming a double seal. This further improves the sealing performance of the spraying device and reduces the risk of media leakage. This fixture also functions as an external connection point for compressed air, spray medium, and protective medium. Compressed air is connected via a connector, the spray medium pipe supplies the spray medium, and the protective medium pipe supplies the protective medium, meeting the needs of the spraying device in different working scenarios and achieving the integration of multiple functions.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4. This utility model provides a technical solution:

[0024] A fixing fixture for a spraying device includes a protective pipe 1, a connecting support 2, a connecting pipe 3, a connecting member 4, a nozzle 5, and a connector 6. The connecting support 2 is disposed on the outer wall of the protective pipe 1. The connecting pipe 3 is inserted into the inside of the protective pipe 1, and one end of the connecting pipe 3 is connected to the nozzle 5. The nozzle 5 is located inside the protective pipe 1. The connector 6 is installed at the other end of the connecting pipe 3 for connecting to compressed air. The bottom of the connector 6 is connected to a spraying medium pipe 10 for supplying spraying medium (such as paint, abrasive, or chemical agent). Each component can be disassembled and installed independently for easy maintenance and replacement. The protective pipe 1 provides rigid support to reduce the vibration of the nozzle 5 during operation.

[0025] Furthermore, the connecting support 2 includes a flange 21 and a boss tube 22. The boss tube 22 is welded to one side of the flange 21. One end of the protective tube 1 passes through the boss tube 22 and extends to one side of the flange 21. The top of the boss tube 22 is threaded with a first locking screw 23 to limit the position of the protective tube 1. The bottom of the first locking screw 23 abuts against the outer wall of the protective tube 1 to fix the position of the protective tube 1.

[0026] The first locking screw 23 can adjust the extension length of the protective tube 1 to adapt to different working conditions.

[0027] Specifically, a protrusion 24 is provided on the side of the flange 21 away from the boss tube 22, and the flange 21 and the boss tube 22 are made of stainless steel.

[0028] Stainless steel is corrosion-resistant and wear-resistant, making it suitable for harsh industrial environments and enhancing stability. The protrusion 24 on the flange 21 can increase the contact pressure with the equipment and reduce vibration transmission. When fixed, it can make the connecting support 2 and the machine form stronger compressive stress. Due to the difference in connection method and material between the connecting support 2 and the machine, the impact of machine vibration on the mechanism can be minimized. The boss tube 22 and the protrusion 24 form a guide to make the mechanism run more smoothly.

[0029] Furthermore, the connector 4 includes a tapered sleeve 41, an abutment ring tube 42, and a locking nut 43. The tapered sleeve 41 and the abutment ring tube 42 are both sleeved on the outer wall of the connecting pipe 3. The outer wall of the tapered sleeve 41 abuts against the inside of one end of the protective pipe 1. One end of the abutment ring tube 42 is inserted into the inside of the tapered sleeve 41, and one side of the abutment ring tube 42 abuts against the end of the protective pipe 1. The locking nut 43 is threaded onto the outer wall of the connecting pipe 3, and one side of the locking nut 43 abuts against one side of the abutment ring tube 42.

[0030] Specifically, the outer wall of the connecting pipe 3 is provided with an external thread that is compatible with the locking nut 43, and the locking nut 43 is threadedly connected to the external thread.

[0031] Specifically, both the tapered sleeve 41 and the abutment ring 42 are made of elastic rubber material.

[0032] The elastic rubber material can absorb vibration and prevent the threads from loosening. The tapered sleeve 41 fits tightly with the protective tube 1 to prevent media leakage.

[0033] The tapered sleeve 41 and the abutment ring tube 42 are fitted onto the connecting tube 3. The tapered sleeve 41 and the abutment ring tube 42 are subjected to superimposed forces to fix the spray gun. The abutment ring tube 42 is subjected to the force applied by the locking nut 43 and moves forward, while applying the same force to the tapered sleeve 41. The tapered sleeve 41 is blocked by the protective tube 1 and begins to apply the opposite force to the abutment ring tube 42. The abutment ring tube 42 is affected by the force applied by the tapered sleeve 41 and the locking nut 43 and its design shape. The protective tube 1 completes the fixation of the connecting tube 3.

[0034] The locking nut 43 is connected to the connecting pipe 3 by threads. The threaded connection can ensure the firmness of the connection and the service life.

[0035] Specifically, a support ring 7 is fixedly installed on the inner wall of the end of the protective tube 1 away from the connector 4, and one end of the connecting tube 3 passes through the support ring 7 and is fixedly installed with the nozzle 5.

[0036] The support ring 7 ensures that the nozzle 5 is centered, improving the uniformity of spraying.

[0037] Specifically, a protective medium tube 8 for supplying external protective medium is installed at the bottom of one end of the protective tube 1, and a second locking screw 9 for auxiliary contact with the connecting tube 3 is threaded on one side of the protective medium tube 8.

[0038] The protective medium tube 8 is used to transport the protective medium (such as inert gas or coolant). The protective medium tube 8 can be filled with gas or liquid to optimize the spraying effect (such as atomization control or cooling). The second locking screw 9 enhances the stability of the connecting tube 3 and prevents the nozzle 5 from deviating.

[0039] Working principle: When this utility model is used, the spraying medium (such as paint, abrasive or chemical agent) enters the connecting pipe 3 through the spraying medium pipe 10. Driven by compressed air connected by the connector 6, the medium is transported to the nozzle 5 along the connecting pipe 3. The protective medium (such as inert gas or coolant) enters the interior of the protective pipe 1 through the protective medium pipe 8, forming an environment surrounding the nozzle 5. The atomization effect, temperature or anti-oxidation of the sprayed medium can be adjusted. The nozzle 5 sprays the medium evenly under high pressure. The protective pipe 1 provides a stable environment and reduces external interference. The spraying medium and the protective medium can be controlled independently, which can optimize the process effect (such as fine atomization or anti-splash). The protective pipe 1 isolates external airflow disturbances and ensures accurate spray trajectory.

[0040] The connecting pipe 3 is fixed inside the protective pipe 1 by the connector 4. When the locking nut 43 is tightened, it pushes the abutting ring pipe 42 and the tapered sleeve 41 to expand, thereby achieving radial locking and sealing. After the locking nut 43 is loosened, the sliding connecting pipe 3 can be used to finely adjust the extension length of the nozzle 5. Then, it is fixed with the second locking screw 9. The flange 21 is fixed to the equipment by bolts. The boss pipe 22 and the protective pipe 1 are locked together by the first locking screw 23 to form a rigid support structure.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
