Description

Technical Field

[0001] This utility model relates to the field of pneumatic actuator manufacturing technology, and more specifically, to a pneumatic actuator spraying fixture. Background Technology

[0002] To increase the surface corrosion resistance of the gear and rack pneumatic actuator cylinder and to enhance the color diversity of the cylinder's appearance, the outer surface of the cylinder is typically treated with epoxy resin powder coating followed by baking. However, this process presents two technical challenges that often necessitate multiple manual steps. First, during epoxy resin powder coating, all threaded holes, large holes, top holes, bottom holes, and stepped holes on the cylinder must be shielded with conical rubber plugs. If epoxy resin powder enters these holes, the thickness of the powder will affect the assembly progress of the gear and rack pneumatic actuator. Second, the baking process requires temperatures exceeding 250 degrees Celsius. Ordinary conical rubber plugs cannot withstand such high temperatures and will melt during baking, contaminating the cylinder.

[0003] According to the patent document with publication number CN210411250U, the device uses the cylinder as the basis for processing. As long as the relative position is determined, pneumatic components and special tooling can be used to efficiently mask the parts of the cylinder that do not need to be painted. The masking can be placed and removed in one go with the help of external force, reducing manpower and time. The rubber parts and the cylinder will not be baked at high temperature together, so there is no need to use high temperature resistant rubber, which reduces material costs.

[0004] However, in the aforementioned patent documents, when spraying the cylinder body, some powder will inevitably splash onto the threaded post. Over time, the threaded post will need to be replaced periodically. However, since the threaded post is installed as a single piece on the shielding plate, it is difficult to replace it quickly. At the same time, there are grooves on the side wall of the cylinder body, and dust easily accumulates in these grooves. It is impossible to clean the grooves of the cylinder body again before spraying to improve the spraying quality.

[0005] To address the aforementioned technical shortcomings, a solution is provided. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, this utility model provides a pneumatic actuator spraying fixture.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A pneumatic actuator spraying fixture includes a pneumatic actuator body and a bottom support component disposed at its bottom. Three sets of support plates are disposed on the outer side of the pneumatic actuator body. A cylinder is disposed on the side wall of the support plate near the pneumatic actuator body. The output end of the cylinder is connected to a side baffle plate through a replacement component. A dust removal component for auxiliary dust removal of the pneumatic actuator body is disposed below the cylinder.

[0009] The dust removal assembly includes a dust removal box fixedly connected to a support plate. A piston plate is slidably arranged inside the dust removal box. A transmission rod is fixedly arranged on the side wall of the piston plate. The end of the transmission rod extends movably through to the outside of the dust removal box and is fixedly arranged with a connecting plate. The top of the connecting plate is fixedly connected to a side baffle plate.

[0010] Furthermore, a vent is inserted into the side wall of the dust collector near the support plate, and an air inlet pipe and a dust removal pipe are inserted into the side wall of the dust collector near the side baffle plate. A one-way valve is provided on the outer wall of both the air inlet pipe and the dust removal pipe.

[0011] Furthermore, a horizontal pipe is fixedly installed at the output end of the dust removal pipe, and multiple sets of nozzles are fixedly installed at the output end of the horizontal pipe. The horizontal pipe is fixedly connected to the side baffle, and the output end of the nozzle is oriented towards the pneumatic actuator body.

[0012] Furthermore, the replacement component includes multiple sets of fixing holes opened above the side shield, with side threaded posts provided in the fixing holes. A T-shaped groove is also provided on the outer wall of the side shield, and an adjusting rod is rotatably arranged inside the T-shaped groove. The end of the adjusting rod extends outside the T-shaped groove and is fixedly installed with a rotating head.

[0013] Furthermore, a fixing plate is threadedly connected to the outer wall of the adjusting rod, and the fixing plate slides in conjunction with the T-shaped groove. Multiple sets of through holes are opened on the outer wall of the fixing plate, and the through holes correspond to the fixing holes.

[0014] Furthermore, a top shield is provided above the pneumatic actuator body.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model extends through the cylinder's extended end. When the piston plate moves to one side of the cylinder, the gas inside the dust collector enters the interior of the transverse tube through the dust collector pipe, and then is blown onto the side wall of the pneumatic actuator body through multiple sets of nozzles to remove dust from the grooves, thus preventing dust from adhering to the grooves of the pneumatic actuator body and affecting the coating quality of the pneumatic actuator body.

[0017] 2. This utility model controls the rotation of the rotating head to move the fixing plate to one side in the T-shaped slide groove until the fixing hole and the through hole are aligned. Then, the side threaded post is pushed outward from one side of the side baffle plate to move the side threaded post outward and complete its replacement. By moving the position of the fixing plate, the replacement of the side threaded post can be completed quickly, improving the replacement efficiency. Attached Figure Description

[0024] 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.

[0025] Example 1: As Figure 1-5 As shown, the pneumatic actuator spraying fixture proposed in this embodiment includes a pneumatic actuator body 1 and a bottom support 2 disposed at its bottom. Three sets of support plates 4 are disposed on the outer side of the pneumatic actuator body 1. A cylinder 5 is fixedly disposed on the side wall of the support plate 4 near the pneumatic actuator body 1. The output end of the cylinder 5 is connected to a side baffle plate 10 through a replacement component. A dust removal component for auxiliary dust removal of the pneumatic actuator body 1 is disposed below the cylinder 5.

[0026] like Figure 1-3 As shown, the dust removal assembly includes a dust removal box 61 fixedly connected to the support plate 4. A piston plate 68 is slidably arranged inside the dust removal box 61. A transmission rod 66 is fixedly arranged on the side wall of the piston plate 68. The end of the transmission rod 66 extends movably through to the outside of the dust removal box 61 and is fixedly arranged with a connecting plate 65. The top of the connecting plate 65 is fixedly connected to the side baffle plate 10.

[0027] like Figure 1-3 As shown, a ventilation hole is inserted on the side wall of the dust collector 61 near the support plate 4. An air inlet pipe 62 and a dust removal pipe 63 are inserted on the side wall of the dust collector 61 near the side baffle plate 10. A one-way valve is provided on the outer wall of both the air inlet pipe 62 and the dust removal pipe 63. A horizontal pipe 64 is fixedly installed at the output end of the dust removal pipe 63. Multiple sets of nozzles are fixedly installed at the output end of the horizontal pipe 64. The horizontal pipe 64 is fixedly connected to the side baffle plate 10, and the output end of the nozzle is set towards the pneumatic actuator body 1.

[0028] It should be explained here that when the cylinder body is fixed by the side baffle plate 10, the extended end of the cylinder 5 extends. When the piston plate 68 moves to one side of the cylinder body, the gas inside the dust collector 61 enters the interior of the transverse pipe 64 through the dust collector pipe 63, and then blows onto the side wall of the pneumatic actuator body 1 through multiple sets of nozzles to remove dust from the grooves, so as to prevent dust from sticking to the grooves of the pneumatic actuator body 1 and thus affecting the coating quality of the pneumatic actuator body 1.

[0029] Gas enters the interior of the dust collector 61 through the air inlet pipe 62. When the piston plate 68 moves to one side of the support plate 4, the gas enters.

[0030] Example 2: Figure 1 , 4 As shown in Figure 5, the pneumatic actuator spraying fixture proposed in this embodiment is an improvement on the embodiment 1. The replacement component includes multiple sets of fixing holes 95 opened above the side baffle plate 10. The fixing holes 95 are provided with side threaded columns to cover the holes on the side wall of the pneumatic actuator body 1. The cross-sections of the fixing holes 95 and the side threaded columns are T-shaped and interlock with each other. The outer wall of the side baffle plate 10 is also provided with a T-shaped slide groove 94. An adjusting rod 93 is rotatably arranged inside the T-shaped slide groove 94. The end of the adjusting rod 93 extends to the outside of the T-shaped slide groove 94 and is fixedly installed with a rotating head.

[0031] like Figure 1 , 4 As shown in Figure 5, a fixing plate 91 is threadedly connected to the outer wall of the adjusting rod 93, and the fixing plate 91 slides in conjunction with the T-shaped slide groove 94. Multiple sets of through holes 92 are opened on the outer wall of the fixing plate 91, and the through holes 92 correspond to the fixing holes 95. Rubber pads are provided on the side wall of the fixing plate 91 opposite to the side threaded column.

[0032] It should be added that when replacing the side threaded post: by controlling the rotation of the rotating head, the fixing plate 91 moves to one side in the T-shaped slide 94 until the fixing hole 95 and the through hole 92 are aligned. Then, the side threaded post is pushed outward from one side of the side baffle plate 10 to move it outward and complete its replacement. By moving the position of the fixing plate 91, the replacement of the side threaded post can be completed quickly, which improves the replacement efficiency.

[0033] like Figure 1 As shown, a top shield 3 is provided above the pneumatic actuator body 1. It should be explained that the bottom support 2 is mainly composed of a bottom support column and a bottom threaded shield column, which serves to shield and support the bottom holes; the top shield 3 is mainly composed of a top drilled positioning column and screws, which serves to shield and connect the top holes. At the same time, the device can be transferred through the top shield 3 for subsequent drying treatment, etc.
