Description

Technical Field

[0001] This utility model relates to the field of metal parts processing technology, specifically a fixing device for metal parts spraying. Background Technology

[0002] In the metal parts spraying process, the uniformity of the spray, the consistency of the thickness, and the flatness of the surface directly determine the product quality, which all depend on the stable fixing of the metal parts. Only by ensuring that the metal parts are firmly fixed can spraying deviations be avoided and the spraying process be executed accurately.

[0003] Existing metal coating fixtures suffer from significant deficiencies in versatility. Most fixtures have rudimentary adjustment structures, allowing only limited angle adjustments, and the adjustment process often relies on manual operation, which is cumbersome and time-consuming. For example, some fixtures use fixed-gap clamping slots or jigs, which cannot securely hold smaller metal parts, causing them to wobble during coating. Conversely, they are unsuitable for larger metal parts, greatly limiting their applicability. This lack of versatility not only reduces the efficiency of metal coating but also severely impacts product quality stability. Companies must frequently replace or modify fixtures when coating different sizes of metal parts, significantly hindering the efficient development of the metal coating industry and failing to meet current demands.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a fixing device for spraying metal parts, including a base 1, a rotating component 2, and a pressing component 3. The rotating component 2 is disposed on the top of the base 1, and the pressing component 3 is disposed on the top of the base 1.

[0021] The rotating assembly 2 consists of a cylinder 201, a rotating shaft 202, a disc 203, a first pulley 204, a motor 205, a second pulley 206, and a belt 207. The cylinder 201 is fixedly mounted on the top of the base 1. The rotating shaft 202 is rotatably mounted inside the cylinder 201. The disc 203 is fixedly mounted on the top of the rotating shaft 202. The bottom of the disc 203 has an annular protrusion, and the top of the cylinder 201 has an annular groove that matches the annular protrusion. This arrangement facilitates the rotation of the disc 203 on the top of the cylinder 201. The first pulley 204 is fixedly mounted on the surface of the rotating shaft 202, and the motor 205 is fixedly mounted on the top of the base 1. The second pulley 206... 206 is fixedly installed on the output shaft of motor 205. Belt 207 is sleeved on the surface of second pulley 206. First pulley 204, second pulley 206, and belt 207 are connected by transmission. When motor 205 is started, the power output by motor 205 is transmitted to the second pulley 206 connected to it, causing it to start rotating. First pulley 204 and second pulley 206 are connected by transmission through belt 207. Under the friction of belt 207, first pulley 204 also rotates. Since first pulley 204 is fixedly connected to shaft 202, the rotation of first pulley 204 will drive shaft 202 to rotate synchronously.

[0022] The pressing assembly 3 consists of a first fixed box 301, a threaded rod 302, a threaded sleeve 303, a second fixed box 304, a sliding rod 305, a sliding sleeve 306, a connecting plate 307, a shaft 308, and a pressing plate 309. The first fixed box 301 is fixedly installed on the top of the base 1. The threaded rod 302 is rotatably installed inside the first fixed box 301. A handle is fixedly installed on the top of the threaded rod 302, which can drive the threaded rod 302 to rotate. The threaded sleeve 303 is threadedly installed on the surface of the threaded rod 302. The second fixed box 304 is fixedly installed on the top of the base 1. The sliding rod 305 is fixedly installed inside the second fixed box 304. The sliding sleeve 306 is slidably installed on the surface of the sliding rod 305. The connecting plate 307 is fixedly installed... Mounted on the side of the sliding sleeve 306, the connecting plate 307 and the threaded sleeve 303 are fixedly connected. By rotating the threaded rod 302, the threaded sleeve 303 can drive the connecting plate 307 to move. At the same time, the guide unit composed of the sliding rod 305 and the sliding sleeve 306 plays a key role. The sliding sleeve 306 is sleeved on the sliding rod 305 and can slide along it. This guide unit effectively restricts the movement direction of the connecting plate 307, ensuring that it can only move smoothly up and down in the vertical direction, avoiding deviation or shaking. The shaft 308 is rotatably mounted inside the connecting plate 307, and the lower pressure plate 309 is fixedly mounted on the bottom of the shaft 308. The bottom of the lower pressure plate 309 is provided with a rubber pad, which can increase the friction between the lower pressure plate 309 and the metal parts.

[0023] In use, the metal part is placed on top of the disc 203. The threaded rod 302 is rotated by the handle. Under the action of the threaded sleeve 303, the sliding rod 305, and the sliding sleeve 306, the connecting plate 307 can move downward, so that the lower pressure plate 309 presses down and fixes the metal parts of different sizes. When the motor 205 is started, the power output of the motor 205 will be transmitted to the second pulley 206 connected to it, so that it starts to rotate. The first pulley 204 and the second pulley 206 are connected by a belt 207. Under the action of the friction of the belt 207, the first pulley 204 also rotates. Since the first pulley 204 is fixedly connected to the rotating shaft 202, the rotation of the first pulley 204 will drive the rotating shaft 202 to rotate synchronously. Since the shaft 308 is rotatably installed inside the connecting plate 307 and the lower pressure plate 309 is fixedly installed at the bottom of the shaft 308, the disc 203 can drive the metal part to rotate, which facilitates the spraying operation of the metal part.
