Description
Technical Field
The invention relates to a pneumatic actuator spraying tool, in particular to a simple spraying tool for improving the spraying efficiency of a gear rack pneumatic actuator cylinder body, and belongs to the technical field of spraying.
Background
The actuating mechanism and the adjusting mechanism of the pneumatic actuator are unified and integrated, and the actuating mechanism comprises a film type actuating mechanism, a piston type actuating mechanism, a shifting fork type actuating mechanism and a gear rack type actuating mechanism. The piston type stroke is long, and the piston type hydraulic pump is suitable for occasions requiring larger thrust; the thin film type stroke is smaller, and only the valve rod can be directly driven. The shifting fork type pneumatic actuator has the characteristics of large torque, small space, more accordant torque curve of the valve and the like, but is not attractive; are commonly used on high torque valves. The rack and pinion type pneumatic actuator has the advantages of simple structure, stable and reliable action, safety, explosion prevention and the like, and is widely applied to production processes with higher safety requirements, such as power plants, chemical industry, oil refining and the like.
In order to increase the corrosion resistance of the surface of the gear rack pneumatic actuator cylinder body and also to increase the color diversity of the appearance of the cylinder body, the outer surface of the cylinder body is usually treated by adopting a process of baking and forming after spraying epoxy resin powder. However, there are two technical difficulties in the implementation of this process, such that it often requires multiple manual treatments to accomplish this.
First, in the epoxy powder spraying process, all screw holes, macropores, top holes, bottom holes and step holes on the cylinder body need to be shielded, and if epoxy powder enters the holes, the assembly progress can be influenced by the thickness of the powder in the subsequent assembly process of the rack and pinion pneumatic actuator. Since the epoxy resin powder is sprayed by electrostatic spraying, insulating materials such as non-conductive nylon, POM, ABS and the like cannot be used, and if the insulating materials are used, the epoxy resin powder cannot be adsorbed at the position nearby the threaded hole and the like around the shielding position, and the epoxy resin powder does not exist in the holes to be shielded, but the periphery of the hole is exposed and whitened due to electrostatic effect, so that the appearance of the cylinder body is influenced. It is therefore common practice to plug the threaded holes with a conical rubber plug of suitable size, while the remainder is masked with an aluminium finish of the size of the hole to be masked, but only by means of manual operations during the placement and removal of these. Particularly, the conical rubber plug for shielding has the defect that a large amount of time and labor are consumed in the placing process because the number of threads on the cylinder body is not small.
Second, in the subsequent baking and forming process, the temperature required by baking and forming is higher than 250 ℃, and the common conical rubber plug cannot bear such high temperature and can be melted in the baking process to pollute the cylinder body. Therefore, in the process, only high-temperature-resistant conical rubber plugs with higher cost can be selected, and after baking and forming, almost considerable manpower and time are required to be spent on placing the conical rubber plugs, and the conical rubber plugs are taken down, so that the efficiency is low in the spraying process of the epoxy resin powder, and the yield is affected.

The fixture mainly comprises a spraying shielding base 1, a spraying shielding hanging plate 2 and a cylinder body side shielding structure 3.
The spraying shielding base 1 is a fixing piece, a bottom big hole positioning column 11 and a thread shielding column 12 are arranged on the spraying shielding base, a straight opening is designed at the top end of the bottom big hole positioning column 11 to ensure complete shielding of a big hole of a cylinder body, a step extending from a plane of the straight opening is used as a positioning plane of the cylinder body, and a step extending from the plane of the straight opening is used as a positioning plane of the ground of the pneumatic actuator body 5. The height of the bottom macroporous positioning column 11 considers the working condition of the electrostatic powder spraying gun, designs a certain height, and ensures that enough space is reserved between the pneumatic actuator body 5 and the spraying shielding base 1 for spraying operation. Because the top end of the thread shielding column 12 is also required to be inlaid with a conical rubber plug 13 made of normal temperature materials, the height of the thread shielding column 12 is slightly lower than that of the bottom macroporous positioning column 11, and finally the thread hole is shielded by the conical rubber plug 13.

The three side plates in the cylinder side shielding structure 3 are shielded by the top hole, the bottom hole, the step hole, and the screw holes of the three faces in the same manner as the spray shielding base 1 and the spray shielding hanger plate 2. Because the three shielding plates are laterally installed, each side plate is connected with one straight travel cylinder, and the thrust of the straight travel cylinder is utilized to support the opposite side shielding plates. Because the gas paths of the straight travel cylinders of the three side shielding plates are the same gas path, the effect of synchronous air inlet and synchronous support is realized.
When the invention works, the pneumatic actuator body 5 is placed on the spraying shielding base 1, and the left straight-travel cylinder 32, the right straight-travel cylinder 34 and the air source interface surface straight-travel cylinder 36 which are connected with the left end surface shielding plate 31, the right end surface shielding plate 33 and the air source interface surface shielding plate 35 are used for simultaneously introducing air, so that three surfaces of the cylinder body are shielded on the three side shielding plates; after the spraying shielding hanging plate 2 is fixed on the pneumatic actuator body 5 through the screw 22, an operator can perform electrostatic spraying of epoxy resin powder on the cylinder body.
After the spraying is finished, the three side shielding plates are connected with the air cylinder to perform reversing air inlet simultaneously, the three side shielding plates are far away from the air cylinder, and an operator transfers the air cylinder to a baking production line through the hanging hooks 23 on the spraying shielding hanging plate 2.
After the baking process is finished, the 4 screws 22 connected with the cylinder body on the spraying shielding hanging plate 2 are disassembled, the spraying shielding hanging plate 2 is taken away, and the pneumatic actuator body 5 with the sprayed epoxy resin powder is completed.
