Description

Technical Field

[0001] This utility model relates to the field of plasma spraying technology for sealing strips, specifically to a clamping gun device for plasma spraying of sealing strips. Background Technology

[0002] Plasma spraying of sealing strips refers to the application of plasma spraying technology to create a coating with special properties (such as wear resistance, corrosion resistance, low friction, and abrasion resistance) on the sealing surface of sealing strips. Its core objective is to significantly improve the overall performance of the sealing strips without altering the base material, thereby meeting the requirements of use under extreme operating conditions (such as high temperature, high speed, and corrosive environments).

[0003] In the plasma spraying process, the sealing strip surface needs to be pretreated with a plasma gun before the paint is applied using a paint spray gun. Existing spray gun fixtures use a universal joint to adjust the spray gun angle, which is difficult to adjust, results in poor angle consistency between production batches, requires highly skilled spraying personnel, and is not conducive to mass production. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a clamping device for plasma spraying of sealing strips. It has good structural rigidity and is not easily deformed. The adjustment and clamping operation is simple. After fixing the adjusted angle, only the plasma gun and spray gun need to be installed for the next batch of production, which reduces the scrap caused by each adjustment and ensures the consistency of spraying between batches.

[0005] The purpose of this utility model is achieved as follows: A plasma spray gun clamping device for sealing strips includes a guide block, a first arc-shaped slide rail, a second arc-shaped slide rail, and a gun clamping assembly. The guide block connects the first and second arc-shaped slide rails, which are arranged one in front of the other. Each arc-shaped section of the first and second arc-shaped slide rails is provided with a gun clamping assembly, which faces the guide block. The gun clamping assembly includes a straight slide block, a gun clamping block, a locking block, and a locking screw. The locking block is slidably disposed within the straight slide block. Each arc-shaped section of the arc-shaped slide rail has an arc-shaped groove corresponding to the locking screw. The locking screw passes through the arc-shaped groove and the straight slide block and is screwed onto the locking block. The end of the straight slide block is connected to the gun clamping block, which is used to clamp a plasma gun or a paint spray gun.

[0006] Preferably, the front side of the guide block is connected to a slidable first arc slide rail, and the rear side is fixedly connected to a second arc slide rail. The bottom of the guide block is provided with a snap-on base, and the top of the guide block is provided with a sealing strip conforming block for guiding and fixing the sealing strip.

[0007] Preferably, the horizontal section at the bottom of the first arc slide rail is slidably disposed with the guide block and locked in place by a locking screw. The guide block is provided with a sliding groove corresponding to the horizontal section, and the horizontal section is provided with a horizontal limiting groove corresponding to the locking screw. The locking screw passes through the horizontal limiting groove and is fixedly connected to the guide block.

[0008] Preferably, the locking block is embedded in the straight groove of the straight groove block, and the straight groove block is provided with a straight through groove corresponding to the locking screw rod to facilitate the passage of the locking screw rod.

[0009] Preferably, a sleeve is provided between the corresponding arc slide rail and the linear slide block, and the sleeve is fitted onto the locking screw rod.

[0010] The beneficial effects of this utility model are: This invention adjusts the angle of the gun clamping assembly using corresponding arc-shaped slide rails. With the combined action of the first and second arc-shaped slide rails, the gun clamping assembly can be adjusted within a range of 0-180°, ensuring that plasma gun operation or paint spraying can evenly cover the surface to be sprayed on the sealing strip. The distance between the gun clamping block and the spraying surface is adjusted using a straight sliding block. The adjustment and clamping operation is simple. After fixing the adjusted angle, only the plasma gun and spray gun need to be installed for the next batch of production. This reduces the skill requirements for workers and is easy to operate, shortening the debugging time and ensuring the consistency of spraying between batches. Multiple plasma guns or paint spray guns can be installed at one time, greatly improving the efficiency of plasma spraying. Attached Figure Description

When the distance between the plasma and the sprayed surface is appropriate and the plasma is evenly covered on the sprayed surface, tighten the locking screw. Make a misalignment mark at the adjustment position with a paint pen, and then the product can be cured for production. Example 2

[0021] See Figure 4 and Figure 5 This utility model relates to a plasma spraying gun clamping device for sealing strips, comprising a snap-fit ​​base 1, a guide block 1, a first arc slide rail 2, a second arc slide rail 3, and a gun clamping assembly. The first arc slide rail 2 and the second arc slide rail 3 are arranged front and rear. The guide block 1 connects the first arc slide rail 2 and the second arc slide rail 3. The front side of the guide block 1 is connected to the slidable first arc slide rail 2, and the rear side is fixedly connected to the second arc slide rail 3.

The sleeve 10 is fitted onto the locking screw rod 8.

[0025] When this device is used for coating on a spray surface, the sealing strip is hung on the sealing strip conformal block at the top of the guide block. The angle position of the clamping gun assembly is adjusted (coarse adjustment) through the corresponding arc slide rail. With the cooperation of the first and second arc slide rails, the clamping gun assembly can be adjusted within the range of 0-180°, so that the coating gun can evenly cover the surface to be sprayed on the sealing strip. Then, the distance between the clamping gun block and the spray surface is adjusted through the straight slide block (fine adjustment). After the air pressure is turned on, the atomization effect of the spray gun is observed. After adjustment, the atomization of the spray gun can evenly cover the working surface at the appropriate distance. Mark the product after spraying. After drying and curing in a high-temperature oven, samples are taken at the end of the production line to test the coating thickness and firmness. After the spraying is qualified, the locking screw is tightened, and the misalignment mark is made with a paint pen. Then, production can be cured.

[0026] This device has multiple nozzles spaced at the front and back. For surfaces requiring a certain coating thickness, if one nozzle is insufficient to coat the surface, two nozzles need to be used at intervals.
