Description

Technical Field

[0001] This utility model belongs to the field of tool carrier technology, and in particular relates to a drilling and milling tool carrier structure applied to PVD hard coating. Background Technology

[0002] Physical vapor deposition (PVD) technology, as a core process in modern cutting tool manufacturing, significantly improves the hardness, wear resistance, and high-temperature oxidation resistance of cutting tools by depositing hard coatings (such as TiN and TiAlN) on the tool surface, thereby meeting the needs of high-speed cutting and machining of difficult-to-machine materials. In the PVD coating process, the tool carrier, as a key component supporting and fixing the tool, directly affects the coating uniformity, production efficiency, and product stability through its structural design.

[0003] Traditional tool carriers typically employ a fixed structure, making it difficult to adapt to rapid changes between different tool types. Furthermore, they are prone to material deformation or failure under high-temperature environments, leading to a decline in coating quality. In addition, existing carriers often rely on single revolution or rotation, making it difficult to achieve omnidirectional coating at complex spatial angles. This is particularly problematic when handling irregularly shaped workpieces such as drilling, milling, and turning tools, where uneven coating thickness and edge effects are particularly pronounced. With the manufacturing industry's ever-increasing demands on tool performance, developing a new type of tool carrier that combines high flexibility, high-temperature resistance, and multi-dimensional motion capabilities has become a key breakthrough direction for improving the efficiency and quality of PVD coatings.

[0004] To address these issues, we provide a drilling and milling tool carrier structure for PVD hard coating, which solves the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a drilling and milling tool carrier structure for PVD hard coating. By combining the secondary self-rotating assembly and the placement assembly, it solves the problems of existing tool carriers lacking high flexibility, high temperature resistance, and multi-dimensional movement capabilities.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a milling and drilling tool carrier structure for PVD hard coating, comprising a secondary self-rotating assembly. A placement component is fixedly connected to the top of the secondary self-rotating assembly. The secondary self-rotating assembly includes a connecting base plate, countersunk bolts A, B, and C. A limiting plate is fitted onto the top of the connecting base plate, a fixing plate is placed on top of the limiting plate, and a support plate is placed on top of the fixing plate.

A pin is fixedly connected to the top of the support plate, and a pin is fixedly connected to one side of the top of the limiting plate. The assembly includes a mounting post with a mounting groove on its surface. A high-temperature resistant elastic ring is inserted into the inner cavity of the mounting groove.

[0029] Example 2

[0030] Please see Figure 1-5Based on Embodiment 1, the top of the connecting base plate 11 is provided with a stepped design, and the limiting plate 15 is sleeved on the step. Limiting holes are formed on the surface of the limiting plate 15, and a baffle plate 111 is fixedly connected to the top of the limiting plate 15. A countersunk hole for mounting a countersunk bolt A12 is formed at the bottom of the connecting base plate 11. A through hole for the countersunk bolt A12 is formed at the top of the fixing plate 16. A threaded hole B for the countersunk bolt A12 and a mounting hole for the countersunk bolt C14 are formed on the surface of the support plate 17. The top of the placement plate 22 is provided with a placement groove, and a key block 27 is placed on the top of the placement groove.

The tool sleeve 24 can be replaced according to production needs. The top of the placement plate 22 is provided with a threaded hole C. The top of the support column 21 is threadedly connected to the inner cavity of the threaded hole C.

[0031] Specifically: The stepped design at the top of the connecting base plate 11 provides a precise installation position for the limiting plate 15, allowing it to be accurately fitted onto the step, enhancing structural stability and assembly accuracy. This contributes to improving the reliability of the entire carrier structure during the PVD coating process. The limiting holes on the surface of the limiting plate 15 can be used for further positioning and fixing, improving structural stability. The top-fixed shielding plate 111 prevents misalignment of the high-temperature elastic lever 110, protecting the normal operation of the structure and improving coating quality. The countersunk hole at the bottom of the connecting base plate 11, the through hole at the top of the fixing plate 16, and the threaded hole B and mounting hole on the surface of the support plate 17 provide accurate installation positions for the countersunk bolts A12 and C14, ensuring a stable connection between components while facilitating assembly and disassembly, improving maintenance efficiency. The placement groove and key block 27 at the top of the placement tray 22 are fixed by countersunk bolts D28, which can be used in this equipment. The installation and fixation of the placement disk 22 prevents displacement during rotation, improving its stability and ensuring the uniformity of the coating. The bent part of the high-temperature resistant elastic lever 110 contacts the gear 25, which can drive the gear 25 to rotate during the movement of the carrier, realizing the secondary rotation of the tool 26, increasing the movement dimension of the tool 26, and helping to improve the uniformity of the coating. The pin hole at the bottom of the gear 25 cooperates with the pin 18 to ensure the stability of the gear 25's rotation. The tool sleeve 24 can be replaced according to production needs, enabling the carrier to adapt to the PVD coating requirements of different types of tools 26, improving the carrier's versatility and flexibility, reducing downtime caused by tool 26 replacement, and improving production efficiency. The threaded hole C on the top of the placement disk 22 is threaded to the top of the support column 21. This connection method facilitates the installation and disassembly of the support column 21 and the placement disk 22, while ensuring a stable connection between the two, which helps to improve the stability of the entire placement assembly 2.

[0032] The working principle of this utility model is as follows: The device is installed with the rotating support body, and the limiting plate 15 is installed with the rotating support body through the limiting hole, so that the device can follow the rotating support body to revolve. The placement disk 22 is driven by the rotating support body to rotate. When the entire carrier rotates, the high temperature resistant elastic lever 110 in the secondary rotation lever assembly 1 contacts the gear 25 in the placement assembly 2, pushing the gear 25 to rotate around the pin 18, so that the tool sleeve 24 and the tool 26 placed therein can achieve secondary rotation. This multi-dimensional movement mode allows the tool 26 to receive coating deposition in all directions during the PVD coating process, effectively solving the problem that traditional carriers are difficult to achieve all-round coating in complex spatial angles, and improving the uniformity and quality of coating.
