Description

Technical Field

[0001] This utility model relates to the field of profile processing equipment technology, and in particular to a drilling and milling composite spindle. Background Technology

[0002] In the profile processing production process, cutting and drilling are required. Existing saw blade clamps and drill bit clamps have different designs and incompatible structures, making them unable to be directly fixed on the same spindle. Traditional profile processing equipment requires two spindles: one for mounting drill bits for milling and the other for mounting saw blades. This necessitates two spindle mechanisms, resulting in complex structures and high costs. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a drilling and milling composite spindle, which can solve the problems of complex structure and high cost in the past.

[0004] To solve the above-mentioned technical problems, this utility model discloses a drilling and milling composite spindle, including a drive motor. The output shaft of the drive motor is fixedly connected to the spindle body. The spindle body is provided with a saw blade clamp, a locking nut, and a drilling and milling cutter shank arranged sequentially along its axial direction. The saw blade clamp is sleeved on the outer periphery of the spindle body. The outer side of the end of the spindle body is provided with a first external thread, and the inner side of the locking nut is provided with a first internal thread. The locking nut is threadedly connected to the end of the spindle body so that the rear end face of the locking nut presses against the saw blade clamp. The front end face of the locking nut is detachably connected to the drilling and milling cutter shank.

[0005] The locking nut has multiple claws extending outward from its front end face. These claws are arranged at intervals along the circumference of the locking nut, and each claw has a second internal thread on its inner side.

[0006] The end of the drill and milling cutter shank facing the chuck has a second external thread, and in the assembled state, the end of the drill and milling cutter shank is threadedly connected to the chuck.

[0007] The end of the drill and milling cutter shank facing away from the chuck is equipped with a quick-connect interface for holding the drill and milling tool.

[0008] The saw blade clamp includes a rear clamp and a front clamp, both of which are fitted onto the spindle body.

[0009] The saw blade clamp also includes a limiting washer, which is located between the rear clamp and the front clamp, and is fitted onto the spindle body.

[0010] Grooves are formed between two adjacent claws.

[0011] The saw blade clamp is equipped with a bearing between itself and the drive motor, so that the saw blade clamp can rotate relative to the drive motor.

[0012] Compared with the prior art, the present invention has the following beneficial effects: by integrating the saw blade clamp and the drill and milling cutter holder onto the spindle body of the same drive motor, a single spindle can perform drilling, milling and cutting operations, replacing the previous method of setting two spindles, simplifying the equipment structure, reducing production costs, and solving the problems of complex structure and high manufacturing cost in the past.

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product, or server that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or servers.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This utility model discloses a specific embodiment of a drilling and milling composite spindle. Please see [link to embodiment]. Figures 1 to 3 The composite spindle includes a drive motor 1, and the output shaft of the drive motor 1 is fixedly connected to the spindle body (not shown). It should be noted that the drive motor 1 is a servo motor, and the output shaft of the drive motor 1 can be fixedly connected to the spindle body via auxiliary components such as gear sets and couplings. The spindle body is a commercially available standard shaft that connects to a motor.

[0021] As an improvement, the spindle body is provided with a saw blade clamp 2, a locking nut 3, and a drill and milling cutter shank 4 arranged sequentially along its axial direction. The saw blade clamp 2 is used to clamp the external saw blade body, the locking nut 3 is used to fix the saw blade clamp 2 and to connect the drill and milling cutter shank 4, which is used to install external drill bits or milling cutters.

[0022] As an improvement, the saw blade clamp 2 is fitted onto the outer periphery of the spindle body. The saw blade clamp 2 includes a rear clamp 22 and a front clamp 21, both of which are fitted onto the spindle body. This can be understood as follows: both the rear clamp 22 and the front clamp 21 have mounting holes for the spindle body to pass through. In the assembled state, the spindle body passes through the mounting holes sequentially, so that both the front clamp 21 and the rear clamp 22 are fitted onto the spindle body. Additionally, the saw blade clamp 2 includes a limiting washer 23, located between the rear clamp 22 and the front clamp 21, and fitted onto the spindle body. The thickness of the limiting washer 23 is less than the thickness of the outer saw blade. The limiting washer 23 mainly serves a protective function, preventing contact between the front clamp 21 and the rear clamp 22. In other embodiments, the limiting washer 23 can be formed on either the front clamp 21 or the rear clamp 22, depending on the actual needs.

[0023] In this embodiment, the outer side of the end of the spindle body is provided with a first external thread, and the inner side of the locking nut 3 is provided with a first internal thread. The locking nut 3 is threadedly connected to the end of the spindle body so that the rear end face of the locking nut 3 presses against the saw blade clamp 2, while the front end face of the locking nut 3 is detachably connected to the drill and milling cutter shank 4. Specifically, multiple jaws 31 extend outward from the front end face of the locking nut 3. The multiple jaws 31 are arranged at intervals along the circumference of the locking nut 3. The inner side of each jaw 31 is provided with a second internal thread, and the end of the drill and milling cutter shank 4 facing the jaws 31 is provided with a second external thread. In the assembled state, the end of the drill and milling cutter shank 4 is threadedly connected to the jaws 31. The cross-sectional shape of the jaws 31 can be one of triangle, polygon, or rectangle. This threaded connection method allows for easy assembly and disassembly of the drill and milling cutter shank 4, improving production efficiency and providing convenient and quick use.

[0024] During operation, since the locking nut 3 is fixedly connected to the spindle body and the drill and milling cutter holder 4, the rotation of the output shaft of the drive motor 1 will drive the spindle body, the saw blade clamp 2 and the drill and milling cutter holder 4 to rotate together.

[0025] To improve convenience, the end of the drill and milling cutter holder 4 facing away from the jaws 31 is provided with a quick-connect interface 41 for holding the drill and milling tool. The quick-connect interface 41 is a type of quick-connect interface used on CNC machine tools on the market, mainly used for quick tool assembly and disassembly. In addition, a groove 32 is formed between two adjacent jaws 31. The groove 32 mainly facilitates the worker's observation of the thread depth, so that the drill and milling cutter holder 4 can be visually judged to determine whether it is installed in place.

[0026] In addition, a bearing is provided between the saw blade clamp 2 and the drive motor 1 so that the saw blade clamp 2 can rotate relative to the drive motor 1.

[0027] Compared with the prior art, the composite spindle of this embodiment integrates the saw blade clamp 2 and the drill and milling cutter holder 4 on the spindle body of the same drive motor 1, so that a single spindle can perform drilling, milling and cutting operations, replacing the previous method of setting two spindles, simplifying the equipment structure, reducing production costs, and solving the problems of complex structure and high manufacturing cost in the past.

[0028] Finally, it should be noted that the drilling and milling composite spindle disclosed in this utility model embodiment is only a preferred embodiment of this utility model and is only used to illustrate the technical solution of this utility model, not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of this utility model.
