Description

Technical Field

[0001] This utility model relates to the field of tool magazine technology, specifically a double-disc, hood-shaped tool magazine. Background Technology

[0002] A tool magazine is a device that provides the necessary tool storage and changing capabilities for automated machining processes. Its automatic tool changing mechanism and ability to store multiple tools have revolutionized traditional, human-intensive production methods. Controlled by computer programs, it can fulfill various machining requirements, such as milling, drilling, boring, and tapping, significantly shortening machining time and reducing production costs—this is the most significant characteristic of a tool magazine system.

[0003] Currently, existing bamboo-shaped tool magazines have tool holders evenly distributed around the tool disc, and their number is limited. If the capacity of the tool magazine is increased, the diameter of the tool disc needs to be enlarged, which not only requires more equipment space, but also takes more time when changing tools as the stroke is longer.

[0004] Therefore, we propose to design a double-blade, hat-shaped tool magazine. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0007] A double-blade tool magazine includes a linear motor. The drive end of the linear motor is fixedly connected to a mounting top cover. A first motor is fixedly connected to the center of the top of the mounting top cover. The drive shaft of the first motor passes through the mounting top cover and is fixedly connected to a first tool disc. A second motor is fixedly connected to one side of the top of the first tool disc. The drive shaft of the second motor passes through the first tool disc and is fixedly connected to a second tool disc. A protective cover is fixedly connected to the bottom of the mounting top cover. A tool changing port is provided on one side of both the mounting top cover and the protective cover. Tool holders are provided around the first and second tool discs.

[0008] The tool holder includes two clamping arms, each with a rotating shaft fixedly connected through its middle. A spring is fixedly connected between the two clamping arms, and a positioning strip is embedded inside the end of each clamping arm away from the spring.

[0009] As a preferred embodiment of the double-blade hooded tool magazine of this utility model, the protective cover corresponds to the external position of the second blade disc, and the distances between the first blade disc and the second blade disc and the inner wall of the mounting top cover and the inner wall of the protective cover are equal, which facilitates the protection of the tool holders on the blade discs. This not only prevents them from being impacted by external forces, but also prevents the tools from being centrifugally ejected and causing injury to the workers.

[0010] As a preferred embodiment of the double-blade mortise and tenon blade magazine described in this utility model, the twelve blade holders are arranged in a ring and are evenly distributed. The device uses a double blade mortise and tenon arrangement with alternating heights, which can accommodate up to twenty-four blades, doubling the number of blades compared to traditional blade magazines.

[0011] As a preferred embodiment of the double-blade cup holder described in this utility model, the inner wall of the clamping arm is arc-shaped, and a sliding groove is provided at the center of the inner wall of the clamping arm. The positioning strip is slidably connected to the sliding groove, which facilitates the replacement of the positioning strip with positioning strips of different sizes and specifications to suit different tools.

[0012] In a preferred embodiment of the double-blade cup holder described in this utility model, the first and second blades are staggered, and the second blade can rotate at the bottom of the first blade to facilitate the retrieval of tools from the second blade.

[0013] As a preferred embodiment of the double-blade mortise and tenon blade magazine described in this utility model, both the mounting top cover and the protective cover are made of high-strength glass, which facilitates the operator's intuitive control of the blades.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model utilizes the cooperation between the first cutter head, the second cutter head, and the protective cover. By employing a double-layered, staggered, distributed cutter head, the equipment occupies less space than a traditional conical cutter head, but doubles the tool capacity, greatly improving the tool load-bearing capacity. Simultaneously, when switching tools, both motors work together, facilitating rapid switching of the waiting tool to the tool changing port and ensuring tool changing efficiency.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] Please see Figure 1-3 This utility model provides a double-blade cup holder, including a linear motor 1, a mounting top cover 2 fixedly connected to the drive end of the linear motor 1, a first motor 3 fixedly connected to the center of the top of the mounting top cover 2, a drive shaft of the first motor 3 passing through the mounting top cover 2 and fixedly connected to a first blade disc 4, a second motor 5 fixedly connected to one side of the top of the first blade disc 4, a drive shaft of the second motor 5 passing through the first blade disc 4 and fixedly connected to a second blade disc 6, and a protective cover 8 fixedly connected to the bottom of the mounting top cover 2.

[0025] The first cutter head 4 and the second cutter head 6 are staggered. The second cutter head 6 can rotate at the bottom of the first cutter head 4, making it easy to take out the cutting tool from the second cutter head 6.

[0026] In this embodiment, the protective cover 8 corresponds to the external position of the second cutter head 6. The distances between the first cutter head 4 and the second cutter head 6 and the inner wall of the mounting top cover 2 and the inner wall of the protective cover 8 are equal, which facilitates the protection of the cutter holder 7 on the cutter head. This not only prevents it from being impacted by external forces, but also prevents the cutter from centrifugally detaching and causing injury to the workers.

[0027] Both the top cover 2 and the protective cover 8 have a tool changing port 9 on one side, and the first tool disc 4 and the second tool disc 6 are both provided with tool holders 7 around their sides.

[0028] In this embodiment, there are twelve tool holders 7, which are evenly distributed in a ring. The device uses a double tool disc with alternating heights, which can accommodate up to twenty-four tools, doubling the number of tools compared to traditional tool discs.

[0029] In this embodiment, both the top cover 2 and the protective cover 8 are made of high-strength glass, which makes it easy for staff to intuitively control the knife.

[0030] The tool holder 7 includes two clamping arms 701. A rotating shaft 702 is fixedly connected through the middle of each clamping arm 701. A spring 703 is fixedly connected between the two clamping arms 701. A positioning strip 704 is embedded in the end of the clamping arm 701 away from the spring 703.

[0031] The inner wall of the clamping arm 701 is arc-shaped, and a groove 10 is provided at the center of the inner wall of the clamping arm 701. The positioning strip 704 is slidably connected to the groove 10, which facilitates the replacement of the positioning strip 704 with positioning strips 704 of different sizes and specifications that are suitable for different cutting tools.

[0032] When in use, first connect the linear motor 1 to the external power supply to facilitate the movement of the cutting tool and tool head to the underside of the tool head of the external lathe equipment for easy tool changing.

[0033] When the first motor 3 and the second motor 5 are connected to an external power source, the first motor 3 can drive the first tool disc 4 to rotate, and the second motor 5 can drive the second tool disc 6 to rotate, thereby adjusting the tool position.

[0034] When changing the tool in the first tool turret 4, simply switch the corresponding tool holder 7 in the first tool turret 4 to the tool changing port 9 to change the tool.

[0035] When changing the tool in the second tool turret 6, the position of the second motor 5 must first be as close as possible to the tool changing chute 9. Only then can the tool to be replaced in the second tool turret 6 protrude outwards from the first tool turret 4, allowing it to be selected and replaced by the lathe. Simultaneously, the first motor 3 drives the first tool turret 4 to rotate, while the second motor 5 drives the second tool turret 6 to rotate. The two motors work synchronously, facilitating the rapid rotation of the tool to be replaced to the tool changing chute 9.

[0036] In this device, the first motor 3 and the second motor 5 are both servo motors, and the drive shafts can rotate in both directions. The coordinated operation between the first motor 3 and the second motor 5 can be achieved through external PLC programming, which is existing technology and will not be described in detail here.

[0037] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
