Abstract
Description
Technical Field
[0001] This utility model relates to the field of vacuum coating technology, specifically to an improved auxiliary tooling for vacuum coating. Background Technology
[0002] Vacuum coating is a technique that deposits materials such as metals, alloys, and compounds onto the surface of a substrate in a vacuum environment using physical or chemical methods to form a thin film with specific functions and properties. During the coating process, auxiliary tooling is required to help limit the workpiece and improve the coating effect.
[0003] However, the existing auxiliary tooling has a relatively fixed size when in use, making it inconvenient to adjust the size according to workpieces of different sizes.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an improved auxiliary tooling for vacuum coating. Utility Model Content
[0005] The purpose of this invention is to provide an improved auxiliary tooling for vacuum coating to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an improved auxiliary tooling for vacuum coating, comprising a mounting frame and an adjustment assembly. The mounting frame has an adjustment hole on its surface. The adjustment assembly for assisting in coating workpieces of different sizes is disposed inside the adjustment hole. The adjustment assembly includes a moving disk, an auxiliary frame, a connecting plate, a screw rod with both positive and negative threads, a worm gear, and a turbine. The auxiliary frame is mounted on the upper end of the moving disk, and the connecting plate is mounted on the lower end of the moving disk. The screw rod with both positive and negative threads is disposed inside the connecting plate, and the worm gear is mounted in the middle of the screw rod. The turbine gear is disposed at the lower end of the worm gear.
[0007] Furthermore, the movable disk and auxiliary frame are arranged symmetrically about the vertical central axis of the mounting frame in two sets, and the movable disk and the adjustment hole are slidably connected.
[0008] Furthermore, a vertical pole is installed at the middle of the lower end of the mounting frame, and the mounting frame and the vertical pole are vertically distributed.
[0009] Furthermore, a base plate is installed at the lower end of the upright, and a fixing hole is installed at the lower end of the base plate.
[0010] Furthermore, the end of the auxiliary frame is provided with a steering component for angular rotation, and two sets of steering components are symmetrically arranged about the vertical central axis of the mounting frame.
[0011] Furthermore, the steering assembly includes a movable hole and a steering rod, and the steering rod is disposed inside the movable hole.
[0012] Furthermore, the steering assembly also includes a connecting rod and a limiting clamp, with the connecting rod connected to the end of the steering rod and the limiting clamp connected to the outside of the connecting rod.
[0013] Furthermore, an extension plate is connected to the end of the connecting rod, and a buffer post is installed on the side of the extension plate.
[0014] This utility model provides an improved auxiliary tooling for vacuum coating, which has the following advantages:
[0015] 1. This utility model is driven by a motor-driven turbine after being fixedly connected by a positive and negative thread screw and a worm gear. After the positive and negative thread screws rotate, they drive the connecting plate and the auxiliary frame to move closer or further away, thereby adjusting the spacing of the auxiliary frame. This allows it to limit the position of coating brackets of different sizes, increasing the range of use. The adjustment hole provides space for the directional movement of the moving plate.
[0016] 2. This utility model uses a fixed hole on the base plate for fixing the bottom of the tooling, a movable hole for installing the connecting rod, and a through hole on the connecting rod to fit a screw for fixing the steering rod and the auxiliary frame. The connecting rod and the limiting clamp rotate with the rotation of the steering rod. The limiting clamp can directly clamp and limit the workpiece on both sides. The extension plate and the buffer column at the end of the auxiliary frame can limit the inner side of the bottom of the workpiece, increasing the workpiece limiting methods.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0022] like Figure 1 As shown, an improved auxiliary fixture for vacuum coating includes a mounting frame 1 and an adjustment assembly 3. The surface of the mounting frame 1 is provided with an adjustment hole 2, which provides space for the directional movement of the moving disk 301. A vertical rod 4 is installed in the middle of the lower end of the mounting frame 1, and the mounting frame 1 and the vertical rod 4 are vertically distributed. A base plate 5 is installed at the lower end of the vertical rod 4. Fixing holes 6 are installed on the base plate 5 for fixing the bottom of the fixture, and fixing holes 6 are installed at the lower end of the base plate 5.
[0023] like Figure 2 As shown, the adjustment assembly 3, used to assist in coating workpieces of different sizes, is disposed inside the adjustment hole 2. The adjustment assembly 3 includes a moving disk 301, an auxiliary frame 302, a connecting plate 303, a positive and negative thread screw 304, a worm gear 305, and a turbine 306. The auxiliary frame 302 is mounted on the upper end of the moving disk 301. Two sets of moving disks 301 and auxiliary frames 302 are symmetrically arranged about the vertical central axis of the mounting frame 1. The moving disk 301 and the adjustment hole 2 are slidably connected, and the connecting plate 303 is mounted on the lower end of the moving disk 301. The connecting plate 303 is equipped with a screw 304 with both positive and negative threads. The screw 304 and the worm gear 305 are fixedly connected and are driven by the turbine 306 driven by the motor. The worm gear 305 is installed in the middle of the screw 304. After the screw 304 rotates, it causes the connecting plate 303 and the auxiliary frame 302 to move closer or further away, thereby adjusting the spacing of the auxiliary frame 302. This allows it to limit the position of coating brackets of different sizes, increasing the range of use. The turbine 306 is installed at the lower end of the worm gear 305.
[0024] like Figure 3 As shown, the auxiliary frame 302 is equipped with a angularly rotating steering assembly 7 at its end. Two sets of steering assemblies 7 are symmetrically arranged about the vertical central axis of the mounting frame 1. Each steering assembly 7 includes a movable hole 701 and a steering rod 702. The movable hole 701 houses the steering rod 702, and the movable hole 701 is used for mounting a connecting rod 703. The steering assembly 7 also includes a connecting rod 703 and a limiting clamp 704. The end of the steering rod 702 is connected to the connecting rod 703, and a through hole in the connecting rod 703 engages with a screw for rotation. The connecting rod 702 and the auxiliary frame 302 are fixedly connected. The connecting rod 703 and the limiting clamp 704 rotate with the rotation of the steering rod 702. The external connection of the connecting rod 703 is the limiting clamp 704. The limiting clamp 704 can directly clamp and limit the workpiece on both sides. The end of the connecting rod 703 is connected to the extension plate 8, and the side of the extension plate 8 is equipped with a buffer post 9. The extension plate 8 and the buffer post 9 can limit the inner side of the bottom of the workpiece at the end of the auxiliary frame 302, increasing the workpiece limiting method.
[0025] In summary, this improved auxiliary tooling for vacuum coating is first based on... Figures 1-3The structure shown allows for workpiece positioning. When the workpiece is positioned, the motor is activated to drive the turbine 306 to rotate. The rotation of the turbine 306 drives the threaded screw 304 and the worm gear 305 to rotate. After the threaded screw 304 rotates, it causes the connecting plate 303 and the auxiliary frame 302 to move closer or further away, thereby adjusting the spacing of the auxiliary frame 302. During adjustment, the extension plate 8 and the buffer column 9 move relative to the auxiliary frame 302, allowing the extension plate 8 and the buffer column 9 to position the inner side of the workpiece bottom. The connecting rod 703 and the positioning clamp 704 can also rotate as the steering rod 702 rotates in the movable hole 701. After adjustment, the steering rod 702 and the auxiliary frame 302 are fixedly connected with bolts. At this time, the positioning clamp 704 can directly clamp and position the workpiece on both sides, thereby increasing the workpiece positioning methods and allowing it to position coating brackets of different sizes, thus increasing its application range.
