Description

Technical Field

[0001] This utility model relates to the field of plasma spraying technology, and in particular to a protective device for plasma spraying workpiece tooling. Background Technology

[0002] Plasma spraying is a technology for strengthening and modifying the surface of materials. It can give the surface of workpieces properties such as wear resistance, corrosion resistance, high temperature oxidation resistance, electrical insulation, heat insulation, radiation protection, friction reduction and sealing. In order to avoid the sides of the substrate being sprayed during the plasma spraying process, tooling is usually used to protect the sides of the workpiece.

[0003] A search revealed Chinese Patent Publication No. CN221460481U, which discloses a protective device for a plasma-sprayed workpiece tooling. The device includes a substrate with a groove on the top for placing the workpiece inside and protecting its sides. The bottom of the substrate has a through hole communicating with the groove. After spraying, a second linear motion component drives the plate to move a push rod through the through hole, thereby pushing the workpiece out of the groove for easy removal.

[0004] However, after the workpiece is placed in the groove, there is still a certain gap between the workpiece and the groove, which may affect the protective effect. Utility Model Content

[0005] The purpose of this invention is to provide a protective device for plasma-sprayed workpiece tooling in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A protective device for plasma-sprayed workpiece tooling includes a worktable, with support legs fixedly connected to the four corners of the bottom of the worktable, and mounting bases fixedly connected to both ends of the top of the worktable. A base plate is mounted in the mounting base by a fixing component. A groove is formed on the top of the base plate, and an upper mounting component is provided below the base plate. An airbag is fixedly connected to the side wall of the groove on the top of the base plate. The airbag is located at the upper end of the groove, and an air supply component is provided in the groove for inflating the airbag.

[0008] Preferably, the air supply component includes a slide plate slidably connected in the groove, the shape of the slide plate matching the shape of the groove, the slide plate being located below the airbag, and a number of evenly distributed springs being fixedly connected between the slide plate and the bottom wall of the groove. A number of ventilation chambers are opened in the wall of the substrate, one end of the ventilation chamber communicating with the chamber below the slide plate, and the other end of the ventilation chamber communicating with the airbag.

[0009] Preferably, the bottom of the substrate has several through holes, which are alternately arranged with the springs.

[0010] Preferably, the upper assembly includes several push rods that slide up and down along the through hole. The bottom of the push rod extends out of the worktable and is fixedly connected to a mounting plate. An electric push rod is fixedly connected between the mounting plate and the bottom of the worktable. When the mounting plate is in the lowest position, the top of the push rod is also located in the through hole.

[0011] Preferably, the electric push rods are evenly distributed at both ends of the mounting plate.

[0012] Preferably, the mounting base is U-shaped with the opening facing the center of the worktable, and both ends of the substrate are located inside the mounting base.

[0013] Preferably, the fixing component includes a screw threaded into the top wall of the mounting base, the bottom end of the screw extending into the mounting base and rotatably connected to a pressure plate, the pressure plate abutting against the top of the substrate.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-5 As shown, a protective device for plasma-sprayed workpiece tooling includes a worktable 1. Support legs 101 are fixedly connected to the four corners of the bottom of the worktable 1. Mounting bases 2 are fixedly connected to both ends of the top of the worktable 1. A base plate 3 is mounted in the mounting base 2 by a fixing component. The mounting base 2 is U-shaped with its opening facing the center of the worktable 1. The two ends of the base plate 3 are located in the mounting base 2. A groove is opened on the top of the base plate 3. The depth of the groove is set as needed so that after the workpiece is placed in the groove, the upper surface of the workpiece is not higher than the upper surface of the base plate 3, thus providing comprehensive protection for the workpiece. Several through holes are opened on the bottom of the base plate 3.

[0027] The fixing component includes a screw 201 threaded into the top wall of the mounting base 2. The bottom end of the screw 201 extends into the mounting base 2 and is rotatably connected to a pressure plate 202. The pressure plate 202 abuts against the top of the substrate 3. Tightening the screw 201 drives the pressure plate 202 to rotate downward to fix the substrate 3. Tightening the screw 201 drives the pressure plate 202 to rotate upward to release the substrate 3.

[0028] An airbag 301 is fixedly connected to the side wall of the groove at the top of the substrate 3. The airbag 301 is located at the upper end of the groove. An air supply component is provided in the groove for inflating the airbag 301. The air supply component includes a slide plate 302 slidably connected in the groove. The shape of the slide plate 302 matches the shape of the groove. The slide plate 302 is located below the airbag 301. Several evenly distributed springs 303 are fixedly connected between the slide plate 302 and the bottom wall of the groove. The through holes and springs 303 are staggered. Several ventilation chambers 304 are opened in the wall of the substrate 3. One end of the ventilation chamber 304 communicates with the chamber below the slide plate 302, and the other end of the ventilation chamber 304 communicates with the airbag 301.

[0029] A top assembly is provided below the substrate 3. The top assembly includes several top rods 403 that slide up and down along the through holes. The bottom of the top rods 403 extends out of the worktable 1 and is fixedly connected to the mounting plate 402. An electric push rod 401 is fixedly connected between the mounting plate 402 and the bottom of the worktable 1. The electric push rods 401 are evenly distributed at both ends of the mounting plate 402. When the mounting plate 402 is in the lowest position, the top of the top rod 403 is also located in the through hole, ensuring that the chamber below the slide plate 302 is in a sealed state, so that when the slide plate 302 moves downward, excess gas is squeezed into the airbag 301.

[0030] Working principle: During use, the workpiece to be sprayed is placed in the groove on the top of the substrate 3. The gravity of the workpiece drives the slide plate 302 to move downwards, and the gas in the chamber below the slide plate 302 is transported to the air bag 301 through the ventilation chamber 304 to inflate the air bag 301, so that the air bag 301 fills the gap between the workpiece and the substrate 3, improving the protective effect of the tooling. After the workpiece is placed, the upper surface of the workpiece is not higher than the upper surface of the substrate 3 to ensure the protective effect. After the spraying is completed, the electric push rod 401 drives the mounting plate 402 to move several push rods 403 upwards. The push rods 403 drive the slide plate 302 upwards to push the workpiece out of the groove. As the slide plate 302 moves upwards, the gas in the air bag 301 is drawn back into the groove through the ventilation chamber 304, causing the air bag 301 to deflate, making it easier to push the workpiece out. When the substrate 3 needs to be replaced, the screw 201 is rotated to separate the pressure plate 202 from the substrate 3, and then the substrate 3 is pulled out from the mounting base 2.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
