Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, and in particular to a PVD coating equipment for metal parts. Background Technology

[0002] PVD coating equipment for metal parts involves the continuous development and application of physical vapor deposition (PVD) technology, particularly for improving the surface properties of metal parts. Originating in the mid-20th century, PVD technology has seen increasing industrial demand, especially in aerospace, automotive, and electronics industries, leading to a growing need for high-performance, high-durability metal parts. PVD coating technology not only effectively improves the mechanical properties and corrosion resistance of metal parts but also offers environmental advantages, thus finding widespread application in various fields.

[0003] In existing technologies, most lifting mechanisms in traditional PVD coating devices for metal parts adopt a single-drive structure. However, single-drive structures are prone to speed fluctuations when the load changes, resulting in problems such as overspeeding under light loads and jamming under heavy loads. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a PVD coating device for metal parts.

[0005] This utility model is achieved by the following technical solution: a PVD coating device for metal parts, including a coating device housing, a lifting component is provided inside the coating device housing, and a connecting component is provided outside the coating device housing.

[0006] The lifting assembly includes a coating tank, which is located at the bottom of the inner wall of the coating device housing. A drive motor is fixedly connected to the inner wall of the coating device housing. A motor rotating rod is fixedly connected to the output end of the drive motor. A drive gear is fixedly connected to the outer wall of the motor rotating rod. A support shaft is rotatably connected to the outer wall of the motor rotating rod. A driven limit gear is meshed with the outer wall of the drive gear. A bidirectional threaded rod is fixedly connected to the inner wall of the driven limit gear. A T-shaped groove is formed at the top of the inner wall of the coating device housing. A T-shaped slider is slidably connected to the inner wall of the T-shaped groove. A rotating rod is rotatably connected, and a driving link is rotatably connected to the outer wall of the rotating rod. A central rod is rotatably connected to the inner wall of the end of the driving link away from the rotating rod. A second driving link is rotatably connected to the outer wall of the central rod. A second T-shaped slider is rotatably connected to the inner wall of the end of the second driving link away from the central rod. The inner wall of the second T-shaped slider is threaded to the outer wall of the bidirectional threaded rod. A lifting block is rotatably connected to the outer wall of the central rod. A parts coating box is fixedly connected to the bottom of the lifting block. A guide T-shaped groove is opened on the inner wall of the coating device housing, and a guide T-shaped slider is slidably connected to the inner wall of the guide T-shaped groove.

[0007] As a further improvement to the above solution, the bottom of the support shaft is fixedly connected to the inner wall of the coating device housing, the outer wall of the bidirectional threaded rod is rotatably connected to the inner wall of the coating device housing, the inner wall of the T-shaped slider is threadedly connected to the outer wall of the bidirectional threaded rod, the outer wall of the T-shaped slider is slidably connected to the inner wall of the T-shaped groove, and the end of the guide T-shaped slider away from the guide T-shaped groove is fixedly connected to the surface of the lifting block.

[0008] As a further improvement to the above solution, two coating tanks are provided, two rotating rods are provided, the two rotating rods are symmetrically arranged with the central rod as the center, the symmetrically arranged central rod is rotatably connected to the inner wall of the second T-shaped slider, and two guide T-shaped sliders are provided, the two guide T-shaped sliders are symmetrically arranged with the central rod as the center.

[0009] Through the above technical solution, the drive motor is operated, and the output end of the drive motor rotates the motor rotating rod. The motor rotating rod is supported by the support shaft while rotating. The motor rotating rod rotates the drive gear, and the drive gear meshes with the driven limit gear. The driven limit gear rotates the bidirectional threaded rod, thereby causing the T-shaped slider and the second T-shaped slider to move inward simultaneously along the inner wall of the T-shaped groove and the outer wall of the bidirectional threaded rod.

[0010] As a further improvement to the above solution, the connecting component includes a connecting protrusion, which is fixedly connected to the surface of the coating device housing, and a connecting limiting groove is provided on the top of the connecting protrusion.

[0011] As a further improvement to the above solution, a limiting groove is provided on the left side of the outer shell of the coating device, a connecting slider is slidably connected to the inner wall of the limiting groove, and a limiting plate is fixedly connected to the outer wall.

[0012] As a further improvement to the above solution, two connecting sliders are provided, which are symmetrically arranged with the motor rotating rod as the center, and two limiting plates are provided.

[0013] As a further improvement to the above solution, a limiting spring is fixedly connected to the top of the limiting plate, the top of the limiting spring is fixedly connected to the inner wall of the coating device housing, the outer wall of the connecting slider is slidably connected to the inner wall of the coating device housing, the top of the connecting slider penetrates through the inner wall of the coating device housing and extends therethrough, and an operating ring is fixedly connected to the top of the connecting slider.

[0014] With the above technical solution, when it is necessary to connect multiple coating device housings, the connecting protrusion of the coating device housing with the same structure is installed into the limiting groove opened in another coating device housing, and then the operating ring is pulled upward to drive the connecting slider.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a drive motor to rotate a motor rotating rod at its output end. This rotating rod is supported by a support shaft. The motor rotating rod rotates a drive gear, which meshes with a driven limit gear. The driven limit gear rotates a bidirectional threaded rod, causing T-shaped sliders and T-shaped slider two to move inwards simultaneously along the inner wall of the T-shaped groove and the outer wall of the bidirectional threaded rod. This, in turn, causes the T-shaped sliders and T-shaped slider two to drive symmetrically arranged rotating rods, which in turn drive a drive connecting rod and a second drive connecting rod to push a central rod inwards. Under the weight of the lifting block and the push of the drive connecting rod and the second drive connecting rod, the central rod moves downwards. Finally, the central rod drives the lifting block, which in turn drives the guide T-shaped slider to slide downwards along the guide T-shaped groove. Simultaneously, the lifting block drives the part coating box to slide into the coating tank. This dual-drive balancing structure ensures consistent contact depth between the part and the coating solution, improving the uniformity of the coating thickness.

[0016] This invention allows for the connection of multiple coating device housings when they need to be connected. The process involves inserting a connecting protrusion into a limiting groove in another coating device housing with the same structure. Then, by pulling an operating ring upwards, the operating ring moves a connecting slider, which in turn compresses a limiting plate and a limiting spring, thus fully inserting the connecting protrusion into the limiting groove. Once the connecting protrusion is fully inside the limiting groove, the connecting slider aligns with it. Releasing the operating ring allows the connecting slider to move downwards under the pressure of the limiting spring, locking it into the connecting limiting groove at the top of the connecting protrusion. This allows multiple coating device housings to be connected, and through modular splicing, they can be flexibly combined into a linear configuration. The shorter distance between adjacent housings after assembly saves space. Attached Figure Description

[0022] The bottom of the support shaft 205 is fixedly connected to the inner wall of the coating device housing 1. The outer wall of the bidirectional threaded rod 207 is rotatably connected to the inner wall of the coating device housing 1. The inner wall of the T-shaped slider 209 is threadedly connected to the outer wall of the bidirectional threaded rod 207. The outer wall of the T-shaped slider 214 is slidably connected to the inner wall of the T-shaped groove 208. The end of the guide T-shaped slider 218 away from the guide T-shaped groove 217 is fixedly connected to the surface of the lifting block 215.

[0023] There are two coating tanks 201 and two rotating rods 210. The two rotating rods 210 are symmetrically arranged with the central rod 212 as the center. The symmetrically arranged central rod 212 is rotatably connected to the inner wall of the T-shaped slider 214. There are two guide T-shaped sliders 218.

[0024] The connecting component 3 includes a connecting protrusion 301, which is fixedly connected to the surface of the coating device housing 1. A connecting limiting groove 302 is provided on the top of the connecting protrusion 301.

[0025] A limiting groove 303 is provided on the left side of the outer shell 1 of the coating device. A connecting slider 304 is slidably connected to the inner wall of the limiting groove 303, and a limiting plate 305 is fixedly connected to the outer wall.

The top of the connecting slider 304 penetrates the inner wall of the coating device housing 1 and extends therethrough. An operating ring 307 is fixedly connected to the top of the connecting slider 304.

[0028] The implementation principle of the PVD coating device for metal parts in this embodiment is as follows: The drive motor 202 is operated, and the output end of the drive motor 202 rotates the motor rotating rod 203. Simultaneously, the motor rotating rod 203 is supported by the support shaft 205. The motor rotating rod 203 rotates the drive gear 204, which meshes with the driven limiting gear 206. The driven limiting gear 206 rotates the bidirectional threaded rod 207, thereby causing the T-shaped slider 209 and T-shaped slider 214 to move inwards simultaneously along the inner wall of the T-shaped groove 208 and the outer wall of the bidirectional threaded rod 207. This, in turn, causes the T-shaped slider 209 and T-shaped slider 214 to move inwards simultaneously. The second slider 214 drives the symmetrically arranged rotating rod 210, which in turn drives the driving connecting rod 211 and the second driving connecting rod 213 to push the central rod 212 inward. This causes the central rod 212 to move downward under the weight of the lifting block 215 and the push of the driving connecting rods 211 and 213. Ultimately, the central rod 212 drives the lifting block 215, which in turn drives the guide T. The slider 218 slides downward along the guide T-shaped groove 217, while the lifting block 215 drives the part coating box 216 to slide into the coating tank 201. This dual-drive balance structure ensures consistent contact depth between the parts and the coating solution, improving the uniformity of the coating thickness. When multiple coating device housings 1 need to be connected, the connecting protrusion 301 of a coating device housing 1 with the same structure is installed into the limiting groove 303 of another coating device housing 1. Then, by pulling the operating ring 307 upward, the operating ring 307 drives the connecting slider 304, which in turn drives the limiting plate 305 to compress the limiting spring upward. Spring 306 is used to fully install the connecting protrusion 301 into the limiting groove 303. When the connecting protrusion 301 is fully inside the limiting groove 303, the connecting slider 304 will be aligned with the connecting limiting groove 302. Then, by releasing the operating ring 307, the connecting slider 304 moves downward under the push of the limiting plate 305 by the limiting spring 306, so that the connecting slider 304 is engaged in the connecting limiting groove 302 opened at the top of the connecting protrusion 301. This allows multiple coating device housings 1 to be connected together. Through modular splicing, they can be flexibly combined into a linear type. After combination, the distance between adjacent housings is shorter, saving the equipment's floor space.

[0029] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
