Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a tool head mechanism for CNC lathes. Background Technology

[0002] CNC lathes are widely used mechanical devices in modern manufacturing. The cutter head is a very important key component. It mainly serves as a carrier to hold cutting tools. During the machining process, the cutter head and cutting tools work together to process the product through the drive of the drive components.

[0003] Due to the increasing complexity of the processing technology for products in the current technology, the number of cutting tools required is often two or more. Currently, the combination of the cutter head and the cutting tools is often achieved through a separately set tool holder. Simply put, a mounting port is opened on the side wall of the cutter head, the tool holder is assembled and fixed in the mounting port with screws, and then the cutting tools are assembled and fixed on the cutter head with screws.

[0004] However, it still has many inconveniences in actual operation. As mentioned above, multiple cutting tools are required during processing, and different tools need to be frequently disassembled and assembled during the processing, which is extremely inconvenient. Secondly, according to the working method, cutting tools can also be divided into powered tools and non-powered tools. For non-powered tools, they can be fixed in the manner described above. However, non-powered tools need to be supported by a tool holder and connected to the drive component to achieve transmission. Therefore, multiple machine tools are required to complete the processing of the workpiece. Operators need to frequently transfer the product to be processed between two machine tools, which is not conducive to controlling processing costs and also causes a sluggish processing efficiency. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a tool turret mechanism for CNC lathes. The technical problem this invention aims to solve is: how to reduce processing costs while ensuring processing efficiency.

[0006] The objective of this utility model can be achieved through the following technical solution: A tool turret mechanism for a CNC lathe, comprising a turret body and a plurality of tools, characterized in that the turret body is a regular polygon, and a connection port for connecting the lathe and accommodating a drive component is provided on the side of the turret body. The tools include a plurality of tools, including tool one, a plurality of tools three, and a tool two capable of being driven to rotate by the drive component. Tool one and tool two are detachably connected to the outer wall of the turret body, and tool one and tool two are arranged opposite to each other in the circumferential direction of the turret body. The plurality of tools three are divided into two groups, and the number of tools three in each group is equal. Both groups of tools three are detachably connected to the outer wall of the turret body, one group of tools three is located on one side of tools one and tools two, and the other group of tools three is located on the other side of tools one and tools two.

[0007] The tool turret mechanism disclosed in this application includes a turret body, tool one, tool two, and several tool threes divided into two groups. As prior art, tool one and several tool threes are non-powered tools, while tool two is a powered tool. Compared to the prior art, this application improves the structure of the turret body by adopting a regular polygonal turret body structure. The turret body is mounted on a lathe via a connection port on its side. Tool one, tool two, and several tool threes are detachably connected to the outer wall of the turret body, and the aforementioned tools are spaced apart along the circumference of the outer wall of the turret body. During subsequent machining, the turret body can be driven vertically or horizontally by the lathe, thereby enabling machining of the product surface using tool one, tool two, or any one of tool threes. To address different machining needs in the prior art, the turret body can be rotated adaptively by driving the lathe, thereby achieving the purpose of rotating and adjusting the position of each tool. The rotation of the turret body enables rapid tool changing, eliminating the need for frequent manual disassembly and replacement of different types of tools while the lathe is stopped. Based on this, this application also integrates a second tool, which is a type of powered tool, onto the disc body. It is driven by a drive unit integrated within the disc body's connection port, thus enabling the disc body structure to perform both powered tool (i.e., tool two) and non-powered tool (i.e., tool one and several tools three) machining functions. During machining, the required machining effect can be achieved by relying on the rotation of the disc body, eliminating the need for two machine tools to complete the machining of the product. This effectively ensures machining efficiency while reducing machining costs. It should be further emphasized that the arrangement of tool one, tool two, and several tools three in this application is not random or irregular. Based on the disc body's structure, a single number of tools (i.e., tool one and tool two) are mounted on the outer wall of the disc body and are circumferentially opposite each other. While ensuring that tool one and tool two do not interfere with each other, these two tools can also serve as a distinguishing reference for the positions of the remaining tools three. The tools three are divided into two equal groups and arranged circumferentially on both sides of tool one and tool two along the outer wall of the disc body, maximizing the disc body's load-bearing capacity and machining feasibility.

[0008] In the aforementioned tool turret mechanism for a CNC lathe, a mounting base is fixed to the outer wall of the turret body. The mounting base has a mounting opening on its outer wall facing the side of the turret body. A cutting tool is embedded in the mounting opening and protrudes from the side of the turret body. A bolt is screwed to the end of the mounting base, passing through the shank of the cutting tool to ensure the tool is positioned within the mounting base. Regarding the installation of the cutting tool, due to the machining requirements, a mounting base serving as an assembly medium is fixed to the outer wall of the turret body. The shank of the cutting tool is inserted into the mounting opening on the side wall of the mounting base, and a bolt is screwed into a threaded hole on its upper end face, allowing the bolt to pass through the shank of the cutting tool, thereby fixing the cutting tool and ensuring the feasibility and secure connection of its installation.

[0009] In the aforementioned tool turret mechanism for CNC lathes, a connecting seat is provided on the outer wall of the turret body. A rotating shaft, arranged radially along the turret body and driven to rotate by a driving component, is rotatably connected within the connecting seat. A through-shaft hole is provided on the outer wall of the turret body, extending radially along the turret body and penetrating the inner wall of the connecting port. The second cutting tool is detachably connected to the outer end of the rotating shaft, and the inner end of the rotating shaft extends into the connecting port through the through-shaft hole. As a power cutting tool, the second cutting tool needs to be driven by a driving component installed within the turret body. To ensure power transmission, this application uses a connecting seat with an internally rotatably connected rotating shaft installed on the turret body as the assembly medium for the second cutting tool. Simultaneously, a through-shaft hole is provided on the outer wall of the turret body for the inner end of the rotating shaft to pass through. This achieves the connection and transmission between the inner end of the rotating shaft and the driving end of the driving component, while the second cutting tool can be directly assembled to the outer end of the rotating shaft.

[0010] In the above-mentioned tool turret mechanism for CNC lathe, a number of assembly ports are provided on the outer side wall of the turret body. The assembly ports are all opened along the radial direction of the turret body. The assembly ports are divided into two groups. One group of assembly ports is located on one side of the mounting base and the connecting base, and the other group of assembly ports is located on the other side of the mounting base and the connecting base. The two groups of cutting tools are embedded in the two groups of assembly ports in a one-to-one correspondence. A number of locking holes are provided on one side of the turret body. The locking holes are provided through the hole wall of each assembly port in a one-to-one correspondence. A bolt is screwed into each locking hole. The bolt passes through the cutting tool and positions the cutting tool in the assembly port (12). Based on the aforementioned scheme, the installation of several cutting tools 3 in this application specifically involves first opening an equal number of assembly ports on the outer wall of the disc body, inserting the tool holders of the cutting tools 3 into the assembly ports to achieve the pre-positioning of each cutting tool 3, and simultaneously locking and positioning each cutting tool 3 by screwing bolts 2 into the locking holes opened on the side of the disc body, with the bolts 2 passing through the corresponding tool holders of the cutting tools 3. Compared to cutting tools 1 and 2, since the installation orientation of each cutting tool 3 is arranged radially along the disc body and no driving component is required to drive it, the assembly of cutting tools 3 in this application differs from that of cutting tools 1 and 2, directly eliminating the redundant base structure, thereby reducing the space occupied by the cutting tools 3 on the outer wall of the disc body, and thus maximizing the number of cutting tools 3 that can be assembled on the disc body.

[0011] In the aforementioned tool turret mechanism for a CNC lathe, the turret body is a regular dodecagon, and the first tool, the second tool, and several third tools are arranged correspondingly to several outer side walls of the turret body. This arrangement utilizes the structure of the outer wall of the turret body itself, with its twelve outer side walls, to achieve partitioned installation of each tool, ensuring effective control over the spacing between the tools.

[0012] Compared with existing technologies, the tool turret mechanism for CNC lathes has the following advantages:

[0013] The main carrier is a regular polygonal disc structure. Tool 1, Tool 2 and several Tool 3 are all assembled on the outer wall of the disc. Tool 1 and Tool 2 are opposite each other along the circumference of the disc, and the several Tool 3 are divided into two groups and arranged on both sides of Tool 1 and Tool 2. The disc is directly connected to the machine tool through the connection port. The machine tool can drive the disc to rotate, thereby quickly switching between different tools, effectively ensuring processing efficiency while reducing the processing cost.

[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0023] like Figure 1 , Figure 2 as well as Figure 5 As shown, the tool turret mechanism for CNC lathes includes a turret body 1, a first tool 2, a second tool 3, and several third tools 4. The turret body 1 is a regular polygon, specifically a regular dodecagon. There is one first tool 2 and one second tool 3. There are ten third tools 4. The ten third tools 4 have the same tool holder structure, but the tool tips of the ten third tools 4 are different.

[0024] like Figure 5 As shown, a connection port 14 is provided inside the disc body 1. The connection port 14 is provided through both sides of the disc body 1 and is specifically used to be mounted on the drive mechanism of the machine tool. As a prior art, the machine tool can drive the disc body 1 to move forward, backward, left and right in the horizontal direction and drive the disc body 1 to move up and down in the vertical direction through the drive mechanism. The machine tool can also drive the disc body 1 to rotate circumferentially through the drive mechanism.

[0025] Combination Figure 3 and Figure 6The disc body 1 is provided with a mounting base 5, which is specifically fastened to one side of the outer wall of the disc body 1 by fasteners. A mounting opening 51 is provided on the outer wall of the side of the mounting base 5 facing the disc body 1. The handle of the tool 2 is installed in the mounting opening 51 by insertion. A threaded hole is provided on the top of the mounting base 5, which penetrates the inner wall of the mounting opening 51. The worker can then insert a bolt 52 into the threaded hole. While the bolt 52 is screwed into the threaded hole, the bolt 52 passes through the hole at the handle of the tool 2, thereby positioning the tool 2 and ensuring the stability of the tool 2 mounted on the mounting base 5.

[0026] Combination Figure 7 A connecting seat 6 is also provided on the disc body 1. The connecting seat 6 is fixed to one of the outer side walls of the disc body 1 and is arranged opposite to the mounting seat 5 along the circumference of the disc body 1. A through-shaft hole 11 is opened on the outer side wall of the disc body 1, and the through-shaft hole 11 extends to the inner wall of the connecting port 14. The connecting seat 6 specifically includes an outer seat body and a rotating shaft 61 rotatably connected in the seat body. The second tool 3 is fixed to the groove opened at the outer end of the rotating shaft 61 by means of threads. The inner end of the rotating shaft 61 extends into the connecting port 14 through the through-shaft hole 11. 4. It is worth mentioning that the connection port 14 of the disc body 1 disclosed in this embodiment serves not only to connect the machine tool, but also to house the drive component inside. This structure can be implemented using existing technology, which will not be elaborated on in this embodiment. The inner end of the rotating shaft 61 is connected to the drive component housed in the connection port 14, thereby driving the tool 3. Furthermore, due to the connection between the inner end of the rotating shaft 61 and the drive component, the rotating shaft 61, together with its external seat, can be positioned on the outer wall of the disc body 1.

[0027] Combination Figure 4 Assembly ports 12 are provided on the remaining ten outer side walls of the disc body 1. Ten locking holes 13 are provided on the side of the disc body 1 corresponding to each assembly port 12. Each locking hole 13 penetrates the inner wall of the assembly port 12. During assembly, taking a tool 3 4 as an example, its handle is inserted into the assembly port 12. Then, bolt 2 7 is inserted into the corresponding locking hole 13. The bolt 2 7 is screwed into the locking hole 13 and passes through the handle of the tool 3 4, thereby fixing the tool 3 4.

[0028] During processing, the machine tool drives the disk 1 to move to the designated position, and the product to be processed is processed by tool 1, tool 2, or any tool 3 or 4. When tool changing is required, the machine tool drives the disk 1 to rotate, thereby rotating to the corresponding tool. This eliminates the need for frequent manual tool changing by workers, making operation more convenient. At the same time, it also eliminates the need for frequent machine stops and workers to transport products between two machine tools, resulting in lower costs.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0030] Although this document frequently uses terms such as disc body 1, through-shaft hole 11, assembly port 12, locking hole 13, connection port 14, tool one 2, tool two 3, tool three 4, mounting base 5, mounting port 51, bolt one 52, connection base 6, rotating shaft 61, and bolt two 7, the possibility of using other terms is not excluded.
