Abstract
Description
Technical Field
[0001] This utility model relates to the field of machining technology, and in particular to a rotatable tool holder. Background Technology
[0002] As a key piece of equipment specifically designed for storing punch press cutting tools, the core function of the tool holder is to provide proper storage space for the tools, ensuring that various tools can be arranged neatly and orderly. This greatly facilitates daily tool management and quick retrieval. During the design phase, the tool holder fully considers the specific dimensions and quantity of punch press cutting tools, striving for precise fit and ensuring the stability and rationality of tool storage. Some tool holders are even equipped with a rotating function, ingeniously catering to the diverse needs of actual processing scenarios. Operators can quickly and efficiently retrieve tools according to different processing tasks during operation. Precise positioning and selection of suitable cutting tools can significantly improve work efficiency. However, the current common method of placing cutting tools has drawbacks. Punch press cutting tools are often placed directly on the tool holder. When the tool holder is rotated, the internal cutting tools inevitably shake, causing the cutting edge to frequently collide with the internal structure of the tool holder. This inevitably leads to wear on the cutting edge, and the originally sharp cutting tip gradually becomes dull. Especially for precision punch press cutting tools, this will trigger a chain reaction in subsequent stamping processes, directly weakening the stamping effect, greatly reducing product quality, and failing to accurately meet high-standard processing requirements.

[0025] 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.
[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0028] Example 1
[0029] Reference Figures 2-6 This is the first embodiment of the present invention. This embodiment provides a rotatable tool holder, which includes a fixing component 200, a moving component 300, and a main body component 100. The three components work together to place the tool in the tool holder and fix it, thus avoiding collision between the blade and the internal structure of the tool holder.
[0030] The fixing component 200 includes a fixing member 201, which includes a placement ring 201a, a fixing ring 201b, a support rod 201c, and a hinge rod 201d. The fixing ring 201b is disposed on one side of the placement ring 201a. The support rod 201c is hinged to the outside of the fixing ring 201b. The hinge rod 201d is fixed to the bottom of the support rod 201c.
[0031] After the punch cutter is placed in the placement ring 201a, pressing the cutter downwards moves the hinge rod 201d. The movement of the hinge rod 201d moves the support rod 201c, which in turn moves the fixing ring 201b. The fixing ring 201b moves until it contacts one side of the cutter, thus fixing the cutter. A return torsion spring is fixed to one side of the fixing ring 201b and is fixed to the inner wall of the support rod 201c. When the fixing ring 201b contacts the cutter, it moves, applying a torsional force to the return torsion spring. When the fixing ring 201b separates from the cutter and releases its restraint, the force of the return torsion spring returns the fixing ring 201b to its original position for the next use.
[0032] The movable component 300 is disposed within the placement ring 201a and includes a movable part 301, comprising a movable disk 301a, a slider 301b, a limiting block 301c, and a limiting plate 301d. The movable disk 301a is located within the placement ring 201a, the slider 301b is fixed to one side of the movable disk 301a, the limiting block 301c is located to one side of the slider 301b, and the limiting plate 301d is disposed to one side of the limiting block 301c.
[0033] A limiting groove corresponding to the limiting block 301c is provided on one side of the limiting plate 301d. After the tool is placed in the placement ring 201a, the tool will press against the moving disk 301a. At this time, the moving disk 301a can drive the slider 301b to move. The slider 301b will drive the limiting block 301c to move on one side of the limiting plate 301d. After the tool is placed, the limiting plate 301d can limit the limiting block 301c, thereby preventing the moving disk 301a from returning to its original position and causing the clamping of the tool to loosen.
[0034] Example 2
[0035] Reference Figures 2-6 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0036] Specifically, the fixing component 200 also includes a support member 202, which is disposed on the hinge rod 201d. A positioning strip 202a is inserted into one side of the hinge rod 201d. The positioning strip 202a is rotatably connected to the placement ring 201a through a bearing.
[0037] When the hinge rod 201d moves, it can be supported by the positioning strip 202a to prevent the hinge rod 201d from shifting during movement.
[0038] Specifically, a movable ring 202b is provided at one end of the hinge rod 201d. The movable ring 202b and the hinge rod 201d are hinged together. A positioning post 202c is inserted into the bottom of the movable ring 202b. The movable ring 202b and the positioning post 202c are movably connected.
[0039] When the movable disk 301a moves, it can move the movable ring 202b. The movement of the movable ring 202b can drive the hinge rod 201d to move, thereby fixing the tool. The positioning pin 202c is fixed to the inner wall of the placement ring 201a. The positioning pin 202c can support the movable ring 202b and prevent the movable ring 202b from shifting.
[0040] Specifically, a spring 202d is fixed to the bottom of the moving ring 202b, and the spring 202d is fixed to the inner wall of the placement ring 201a. A moving tube 202e is fixed to the top of the moving ring 202b, and the moving tube 202e is fixed to the bottom of the moving disk 301a.
[0041] When the moving disk 301a moves, it will drive the moving tube 202e to move. The movement of the moving tube 202e will drive the moving ring 202b to move. The movement of the moving ring 202b will apply a compressive force to the spring 202d. The rebound force of the spring 202d will drive the moving ring 202b back to its original position.
[0042] Specifically, the moving component 300 also includes a movable part 302, which is disposed on the slider 301b. A groove X corresponding to the slider 301b is provided on one side of the placement ring 201a, and the slider 301b slides in the groove X.
[0043] When the slider 301b moves, it can move within the groove X, which can support the moving disk 301a and prevent the moving disk 301a from shifting during movement.
[0044] Specifically, a positioning rod 302a is fixed to the inner wall of the slide X, and a slider 301b is sleeved on the outside of the positioning rod 302a. The slider 301b and the positioning rod 302a are movably connected. A turntable 302b is fixed to one side of the limiting block 301c, and the turntable 302b and the slider 301b are hinged.
[0045] When slider 301b moves, it can move on positioning rod 302a, which supports slider 301b and prevents slider 301b from deviating during movement. When it is necessary to release the limit on moving disk 301a, the limit block 301c is moved. At this time, the limit block 301c will separate from the limit groove, thereby releasing the limit on moving disk 301a. When the limit block 301c moves, the turntable 302b can rotate. The turntable 302b supports the limit block 301c and prevents the limit block 301c from deviating during movement.
[0046] Specifically, a first torsion spring 302c is fixed to one side of the turntable 302b, and the first torsion spring 302c is fixed to the inner wall of the slider 301b.
[0047] When the turntable 302b rotates, it can apply a torsional force to the first torsion spring 302c. When the limit block 301c is released, the force of the first torsion spring 302c rotating can drive the limit block 301c to re-engage with the limit groove.
[0048] Example 3
[0049] Reference Figures 1-6 This is the third embodiment of the present invention, which is based on the first two embodiments.
[0050] Specifically, a movable plate 302d is fixed to one side of the limiting block 301c, and a pressing strip 302e is fixed to the top of the movable plate 302d.
[0051] Pressing the pressing strip 302e can move the moving plate 302d. When the moving plate 302d moves, it can drive the turntable 302b to rotate. At this time, the rotation of the turntable 302b can drive the limit block 301c to move.
[0052] Specifically, it also includes a main component 100, which is disposed on the placement ring 201a, including a placement frame 101 and a tool holder body 102. The placement frame 101 is sleeved on the outside of the placement ring 201a, and the tool holder body 102 is sleeved on the outside of the placement frame 101.
[0053] The placement rack 101 can support the placement ring 201a. Rotating the tool holder body 102 can drive the placement rack 101 to rotate, thus presenting different tools to the user for easy access.
[0054] Specifically, a base 103 is provided at the bottom of the tool holder body 102.
[0055] The base 103 is rotatably connected to the bottom of the tool holder body 102 via a bearing. The base 103 can support the tool holder body 102 and prevent the tool holder body 102 from shifting.
[0056] In use, the punch press tool is first placed in the placement ring 201a. As soon as the tool is placed in, it will squeeze the moving disk 301a. The moving disk 301a is driven by the force to move the slider 301b fixed on one side synchronously. The slider 301b slides along the groove X opened in the placement ring 201a. The positioning rod 302a in the groove X provides support for the slider 301b to ensure its smooth movement. The slider 301b then drives the limiting block 301c to move on the side of the limiting plate 301d until the limiting block 301c is inserted into the limiting groove of the limiting plate 301d, thus limiting the position of the moving disk 301a and preventing it from returning to its original position and causing the clamping of the tool to loosen.
[0057] At the same time, the downward movement of the moving disk 301a will also drive the moving tube 202e fixed at the bottom to move together. The moving tube 202e pulls the moving ring 202b connected to it. The moving ring 202b moves down along the positioning post 202c and squeezes the spring 202d. The movement of the moving ring 202b drives the hinge rod 201d to move through the hinge. The positioning strip 202a on one side of the hinge rod 201d ensures that its movement direction is stable and prevents deviation. The hinge rod 201d further drives the support rod 201c that is hinged to it, so that the fixed ring 201b moves closer to the tool side and finally contacts the tool to achieve fixation. During this process, the return torsion spring on the inner wall of the fixed ring 201b is subjected to force and torsion.
[0058] When it is necessary to release the fixation and limitation of the tool, press the pressing strip 302e on one side of the limiting block 301c. The pressing strip 302e drives the moving plate 302d to move, which in turn causes the turntable 302b to rotate. The rotation of the turntable 302b causes the limiting block 301c to separate from the limiting groove, releasing the limitation of the moving plate 301a. At the same time, the first torsion spring 302c is torn by force. After the pressing strip 302e is released, the first torsion spring 302c rotates back, causing the limiting block 301c to reset. The fixing ring 201b also returns to its original position due to the force of the reset torsion spring, making it convenient for the next use.
[0059] During the use of the tool holder, if different tools need to be selected, the tool holder body 102 can be rotated. The tool holder body 102 drives the placement ring 201a and its internal components to rotate together through the placement frame 101. The base 103 provides stable support for the tool holder body 102 through the bearing connection to prevent displacement, thereby rotating the required tool to a position that is easy to pick up. In the whole process, all components work closely together to efficiently and conveniently realize the functions of tool storage, fixing, and retrieval, ensuring smooth operation of punch press processing.
[0060] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
