Abstract
Description
Technical Field
[0001] This utility model relates to the field of machining technology, and more specifically, to a power tool holder input shaft transmission connection structure. Background Technology
[0002] Traditional radial and axial power tool holders use rigid connections for their input shafts. This type of transmission requires extremely high coaxiality between the input shaft of the power tool holder and the power output shaft of the power turret on the machine tool. Otherwise, the bearings of both can be easily damaged. Currently, the highest coaxial accuracy that can be achieved is 0.01~0.02mm. This is barely usable on low-speed power turrets, but the bearing life is generally not very long. When the power tool holder is installed on a high-speed power turret with a speed exceeding 10,000 rpm, the bearings of both the power tool holder and the turret will be damaged quickly. Utility Model Content
[0003] This utility model provides a power tool holder input shaft transmission connection structure, which aims to improve the technical problem that the existing connection between the power tool holder input shaft and the power tool turret output shaft is a rigid connection, which easily leads to the circumference damage of the power tool holder and the tool turret due to the high-speed rotation of the tool turret.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a power tool holder input shaft transmission connection structure, including a tool holder body, the tool holder body including a first input shaft, a flexible coupling being sleeved on one end of the first input shaft extending out of the tool holder body, and a second input shaft being installed on the other end of the flexible coupling.
[0005] Furthermore, the flexible coupling is a diaphragm coupling, with the first input shaft inserted and installed at one end of the diaphragm coupling, and the second input shaft inserted and installed at the other end of the diaphragm coupling.
[0006] Furthermore, let the length of the second input shaft be X, where 46mm ≤ X ≤ 50mm.
[0007] Furthermore, let the length of the first input shaft extending out of the tool holder body be Y, where 13mm≤Y≤15mm.
[0008] Furthermore, one end of the second input shaft is cylindrical, and the other end is flat.
[0009] Compared with the prior art, the beneficial effects of this utility model are: This utility model discloses a power tool holder input shaft transmission connection structure. The structure is simple and ingeniously designed, including a tool holder body. The tool holder body includes a first input shaft. A flexible coupling is fitted onto one end of the first input shaft extending from the tool holder body. A second input shaft is installed at the other end of the flexible coupling. In use, the second input shaft is inserted into the tool turret. The tool turret drives the rotation of the second input shaft, which in turn drives the rotation of the first input shaft through the flexible coupling. After disconnecting the power tool holder input shaft, a set of flexible couplings is installed. The flexible couplings solve the problem of coaxiality deviation, thereby avoiding damage to the internal bearings of both the high-speed rotating tool turret and the power tool holder, and improving the service life of the power tool holder and the tool turret.

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0014] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0015] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0016] Example Reference Figure 1-2 As shown, this utility model discloses a power tool holder input shaft transmission connection structure, including a tool holder body 10. The tool holder body 10 includes a first input shaft 101. A flexible coupling 102 is sleeved on one end of the first input shaft 101 extending out of the tool holder body 10, and a second input shaft 103 is installed on the other end of the flexible coupling 102. Specifically, during installation, the second input shaft 103 is inserted into and installed on the tool turret. The rotation of the tool turret drives the rotation of the first input shaft 101 of the power tool holder through the second input shaft 103 and then through the intermediate flexible coupling 102, thus completing the power transmission. Compared with the traditional rigid connection transmission method, the flexible coupling 102 solves the problem of coaxiality deviation and avoids damage to the bearings inside the power tool holder and tool turret caused by coaxiality deviation.
[0017] In this embodiment, the flexible coupling 102 is a diaphragm coupling. The first input shaft 101 is inserted and installed at one end of the diaphragm coupling, and the second input shaft 103 is inserted and installed at the other end of the diaphragm coupling. The diaphragm coupling essentially uses the deformation of an elastic metal diaphragm to transmit power, automatically correct shaft system deviations, and effectively avoid damage to the internal bearings of the power turret and power tool holder caused by coaxiality deviation.
[0018] Reference Figure 1-2As shown, let the length of the second input shaft 103 be X, 46mm≤X≤50mm. The second input shaft 103 is used for insertion and installation on the tool turret. In this embodiment, the length of the second input shaft 103 is preferably 48mm, because the second input shaft 103 bears a large torque, which would cause deformation and breakage due to the large torque. If it is too small, the flexible coupling 102102 cannot be installed. Further, let the length of the first input shaft 101 extending out of the tool holder body 10 be Y, 13mm≤Y≤15mm. In this embodiment, the length of the first input shaft 101 extending out of the tool holder body is preferably 14mm. The first input shaft 101 must meet the installation requirements of the flexible coupling 102 but cannot be too long. If it is too short, the flexible coupling 102102 will not be installed securely; if it is too long, the torque will be too large and it will break easily.
[0019] Reference Figure 1-2 As shown, the second input shaft 103 has a cylindrical shape at one end and a flat shape at the other end. The cylindrical end is used to connect to the flexible coupling 102 and is adapted to the flexible coupling 102; the flat end is used to connect to the turret and is adapted to the structure of the turret.
[0020] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
