Description

Technical Field

[0001] This utility model relates to the field of valve processing technology, specifically a valve outer surface spraying device. Background Technology

[0002] A valve is a device used to control the flow of fluids (such as liquids, gases, steam, etc.) in a pipeline system. It plays a vital role in many industrial fields and in pipeline transportation systems in daily life.

[0003] In valve manufacturing and subsequent maintenance and refurbishment, the spraying treatment of the valve's outer surface is a crucial process. Traditional valve spraying operations mostly rely on manual operation with handheld spray guns. This method is not only inefficient but also makes it difficult to ensure the uniformity and consistency of the spray. Because manual operation makes it difficult to precisely control parameters such as the distance and angle between the spray gun and the valve surface, as well as the spraying speed, it often results in uneven coating thickness on the valve surface, with some areas being too thick or too thin. An excessively thick coating not only wastes paint material but may also lead to problems such as peeling and cracking due to stress concentration during subsequent use; an excessively thin coating cannot provide sufficient protective performance, affecting the valve's corrosion resistance and durability. Utility Model Content

[0004] The purpose of this utility model is to provide a valve outer surface spraying device to facilitate uniform painting of the valve.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a valve outer surface spraying device, comprising a workbench and a valve, a controller being provided on the front of the workbench, a cavity being provided inside the workbench, a sliding opening being provided on the surface of the workbench, the sliding opening being connected to the cavity, a clamping assembly being provided on the top of the workbench, and a spraying assembly being provided on the top of the workbench.

[0006] Preferably, the clamping assembly includes: a driving component disposed inside the worktable; and a supporting component disposed on top of the driving component.

[0007] Preferably, the driving component includes: a motor, fixedly installed on one side of the worktable; and a guide rod, symmetrically fixedly installed inside the worktable.

[0008] Preferably, the output end of the first motor is provided with a bidirectional threaded rod, the other end of which movably passes through one side of the outer wall of the worktable, one side of the inner wall of the worktable, and extends to the other side of the inner wall of the worktable, and is rotatably connected to the worktable via a bearing. The outer wall of the bidirectional threaded rod is symmetrically threaded with a movable block one, and the outer wall of the first guide rod is symmetrically slidably fitted with a movable block two. The movable block two and the movable block one are fixedly connected by a connecting block one. The top of the movable block one movably passes through a sliding opening one and is fixedly installed with a fixed vertical plate. The outer side of one of the fixed vertical plates is fixedly installed with a second motor. The output end of the second motor is provided with a rotating shaft, and the outer wall of the rotating shaft is fixedly fitted with a gear.

[0009] Motor 1 drives the bidirectional threaded rod to rotate. Since the bidirectional threaded rod is threadedly connected to movable block 1, and movable block 2 slides along guide rod 1 and is fixedly connected to movable block 1 via connecting block 1, movable block 1 and movable block 2 can move synchronously towards or away from each other. This allows for wide applicability to various valve models and sizes requiring clamping, enhancing the device's versatility.

[0010] Preferably, the supporting component includes: a circular plate, which is movably fitted inside the fixed vertical plate; and a fixing frame, which is fixedly installed on the outside of the fixed vertical plate.

[0011] Preferably, the circular plate is rotatably connected to the fixed vertical plate via a bearing. The circular plate has two sliding openings equidistantly spaced on its surface. A telescopic rod is fixedly fitted inside the fixed frame. A gear is fixedly fitted on the outer wall of one of the telescopic rods, and the gears mesh with each other. A connecting block is fixedly installed at the telescopic end of the telescopic rod. A push rod is movably mounted on the outer wall of the connecting block. A limit plate is movably mounted at the other end of the push rod. A slider is fixedly installed on the other side of the limit plate. The other side of the slider movably passes through the sliding opening and is fixedly mounted with an arc-shaped support block. A rubber pad is fixedly installed on the outer side of the arc-shaped support block.

[0012] The rotating connection between the circular plate and the fixed vertical plate, along with the equidistant sliding openings on its surface, and the transmission design of components such as the telescopic rod inside the fixed frame, enable multiple arc-shaped support blocks to move synchronously towards the center of the valve under the drive of the second motor. This synchronous circumferential clamping action ensures that the valve is subjected to uniform force in all directions, avoiding valve deformation or insecure clamping due to uneven local force.

[0013] Preferably, the spraying assembly includes: an electric guide rail, fixedly installed on the top of the workbench; and connecting vertical plates, symmetrically fixedly installed on the top of the workbench.

[0014] Preferably, a sliding seat is slidably connected to the outer wall of the electric guide rail, a guide rod two is fixedly installed between the connecting vertical plates, a sliding block is slidably sleeved on the outer wall of the guide rod two, a support frame is fixedly installed on the top of the electric guide rail, the support frame is fixedly connected to the sliding block, a fixing block is symmetrically fixedly installed on the bottom of the support frame, a connecting box is fixedly installed on the bottom of the fixing block, a paint storage tank is fixedly installed on one side of the support frame, a paint inlet pipe is connected to the top of the paint storage tank, a paint extraction pipe is connected to one side of the paint storage tank, a paint pump is connected to the other end of the paint extraction pipe, a paint outlet pipe is connected to the output end of the paint pump, the other end of the paint outlet pipe passes through the top of the support frame and extends to the bottom of the support frame, and is connected to the connecting box, and a spray nozzle is evenly and equidistantly connected to the bottom of the connecting box.

[0015] The sliding connection between the electric guide rail and the slide block, along with the design of the guide rod and sliding block between the vertical plates, ensures that the support frame can remain stable and move along the set trajectory during movement.

[0016] This utility model provides a valve outer surface spraying device. It has the following beneficial effects:

[0017] (1) In this utility model, the valve to be painted is placed between the clamping components. When the motor is started, it drives the bidirectional threaded rod to rotate. The rotation of the bidirectional threaded rod causes the movable block one to move symmetrically along the guide rod one. At the same time, the movable block two also moves. Synchronization is maintained by the connecting block one. The movable block one drives the fixed vertical plate to move until the two fixed vertical plates clamp the two sides of the valve. When the motor is started, it drives the rotating shaft and gear to rotate. The gear meshes with the gear two, driving the telescopic rod to rotate, thereby driving the valve to rotate, so as to achieve the effect of facilitating uniform painting of the valve.

[0018] (2) By activating the telescopic rod, the telescopic rod pushes the limiting plate and the slider to move through the connecting block two and the push rod, thereby adjusting the position of the arc-shaped support block so that it is close to the inner surface of the valve. The rubber pad provides additional support and anti-slip effect, thereby clamping and fixing the valve to prevent it from falling off during the spraying process. Attached Figure Description
