Description

Tool magazine rotary unit

The invention relates to a machining center machine; in particular, it refers to a tool magazine rotating unit matched with the machine.

According to the variety of machining center machines, a variety of structural types have been derived. Taking a portal machining center as an example, it is suitable for drilling, milling, turning and other processing of large workpieces. In order to be able to cope with the aforementioned various processing types and effectively improve work efficiency, known gate-type machining center machines are often equipped with a tool magazine structure on one side in order to quickly exchange appropriate processing tools. Taking a portal-type machining center machine as shown in FIG. 1 as an example, a tool magazine 2 is provided on one side of the spindle 1. The tool magazine 2 includes a rotatable disc-shaped tool disc 2a, and a plurality of tool holders are arranged around the tool disc 2a The section 2b holds machining tools of different shapes. Please cooperate with FIG. 2 again. The cutter disc 2a of the tool magazine 2 of the known portal machining center machine is controlled and rotated by a transmission mechanism disposed below the cutter disc 2a. The transmission mechanism mainly includes a motor 3 and a reduction gear. Gear set 4, wherein the motor 3 is coupled to the side of a base 5 in an upright manner, so that the power output shaft 3a of the motor 3 can be connected to the pinion 4a with a small number of teeth in the reduction gear set 4, and the pinion 4a It then meshes with the large gear 4b with a large number of teeth, and the large gear 4b is combined with the rotating shaft 2c of the tool magazine 2 to achieve the purpose of driving.

It is true that the above-mentioned tool magazine 2 provides the spindle 1 for quick exchange of machining tools, but in practice there are still the following missing, including: 1. The motor 3 and the reduction gear set 4 are hidden in the base 5 near the cutter head 2a. It is not very convenient for inspection or maintenance personnel; 2. The small gear 4a and large gear 4b of the reduction gear set 4 are exposed, and the protection is insufficient; although a shield may be installed outside the reduction gear set 4, but still Inconvenient maintenance due to its poor installation position; 3. In order for the reduction gear set 4 to be driven by the power output shaft 3a, the motor 3 must be installed in an upright manner, but the motor 3 in an upright position easily occupies space.

In addition, FIG. 3 shows a tool magazine 6 mounted on another portal type machining center. The motor 7 and the reduction gear set 8 are hidden inside the base 9, although the reduction gear set 8 is no longer exposed and the protection is improved. Motor, but the motor 7 is still set upright to drive the reduction gear set 8, so it still occupies space. Second, the motor 7 and reduction gear set 8 hidden inside the base 9 It is still inconvenient for maintenance personnel.

In view of this, an object of the present invention is to provide a tool magazine rotating unit, which is convenient for installation and maintenance.

In order to achieve the above object, the present invention provides a tool magazine rotating unit including a base, a disc type tool magazine and a motor. The base has two opposite ends, one end of which is connected to a fixed object; the disc-type tool magazine is rotatably coupled to the other end of the base with a first axis as a center, and the periphery of the disc-type tool magazine A plurality of knife clamping units are provided; the motor is controlled to drive the disc-type tool magazine to rotate, the motor includes a casing and a power output shaft, and at least a part of the power output shaft is located in the casing, and the power output The shaft is centered on a second axis, wherein the first axis is perpendicular to the second axis.

The effect of the present invention is that changing the motor to a horizontal position can not only reduce the occupied space, but also make maintenance more convenient and easy.

In order to explain the present invention more clearly, preferred embodiments are described in detail below with reference to the drawings. Please refer to FIG. 4 to FIG. 6, which is a tool magazine rotating unit 100 of the first preferred embodiment of the present invention, which is applied to a machining center machine using a portal type machining center as an example but not limited thereto. It is to provide the spindle (not shown) of the machining center machine for quick exchange of machining tools.

The detection unit 50 is arranged in a circle. The disc tool magazine 20 is electrically connected to a controller (not shown). When a tool is detected in the clamping position 24 at a specific position, a detection signal will be sent to the controller. The controller will Stop the tool change of the spindle of the machining center.

Please refer to FIG. 7 and FIG. 8 again, the tool magazine rotating unit 200 of the second preferred embodiment of the present invention includes a base 60, a disc type tool magazine 70, a motor 80, and a reduction mechanism 90. The first embodiment is different in that the base 60 includes a base 62 and a support 64. The base 62 is firmly coupled to a fixed object. The support 64 is connected to the base 62 but has a height lower than that of the base 10 in the first embodiment. The disc magazine 70 includes a rotary base 72 and a rotary disc 74. The rotary base 72 is rotatably coupled to the support 64 of the base 60, and the rotary axis is centered on the first axis L1 perpendicular to the ground. 74 is fixed to the top end of the rotary base 72 and a plurality of knife clamping portions 76 are provided on the periphery. The motor 80 and the reduction mechanism 90 are provided on the base 62 of the base 60. The casing 82 of the motor 80 is horizontally arranged, and the power output shaft 84 is still centered on the second axis L2 and is connected to the reduction mechanism 90. The reduction mechanism 90 The rotary base 72 can be driven to rotate.

In the second preferred embodiment, the motor 80 and the reduction mechanism 90 are maintained in a flat manner, so that it does not take up too much space, and it does not affect the installation height position of the disc tool magazine 70, so it can meet the requirements of the machining center machine. Actual use requirements; In addition, the motor 80 and the reduction mechanism 90 are not hidden under the adjacent cutter head 74, so that personnel can still easily install, inspect or maintain them; further, the transmission gear of the reduction mechanism 90 is a cover The body 92 is covered to obtain a good protection effect.
