[0025] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0026] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] See also Figures 1 to 5 , which is a dual-tool magazine machining center of an embodiment of the utility model, includes a base 10, an optical machine 20 installed on one side of the base 10, a flip assembly 30 installed on two opposite sides of the optical machine 20, and a tool magazine 40 respectively connected to each flip assembly 30.

[0029] The optical machine 20 includes a column 21 installed on one side of the base 10 , a spindle box 22 slidably connected to the column 21 , and a spindle 23 rotatably installed on the spindle box 22 ; the spindle box 22 and the spindle 23 are located between the two tool magazines 40 .

[0030] The flip assembly 30 includes a rotary cylinder 31 installed on one side of the column 21, a turntable 32 coaxially connected to the rotor of the rotary cylinder 31, a stopper 33 connected to one side of the outer periphery of the turntable 32, a crossbeam 34 fixedly installed on one side of the turntable 32, and limit columns 35 adjustably installed on opposite ends of the crossbeam 34; the limit columns 35 are located on opposite sides of the turntable 32, and the limit columns 35 are used to abut the stopper 33 to limit the rotation range of the turntable 32.

[0031] Specifically, the opposite ends of the crossbeam 34 are respectively provided with internal threaded holes (not shown), and the limiting column 35 is a screw rod, and the limiting column 35 is screwed with the internal threaded hole so that the position of the limiting column 35 can be fine-tuned as needed. Considering that the machining center generates heat during operation, this heat may cause the spindle 23 to deform or deviate. By adjusting the screwing depth of the limiting column 35 on the crossbeam 34, that is, changing the protrusion of the limiting column 35, the working position of the tool magazine 40 can be fine-tuned to ensure that the tool magazine 40 can always be accurately matched and docked with the spindle 23.

[0032] In this embodiment, the flip assembly 30 further includes a reinforcing column 36 installed on a side of each limiting column 35 close to the turntable 32. The reinforcing column 36 is used to abut the stopper 33 to prevent excessive contact between the stopper 33 and the limiting column 35. If the stopper 33 directly contacts the limiting column 35 and applies excessive pressure, the connection between the limiting column 35 and the internal threaded hole may become loose, thereby affecting the stability and accuracy of the entire flip assembly 30. By adding the reinforcing column 36, a reinforcing support can be formed between the stopper 33 and the limiting column 35, effectively avoiding excessive contact, thereby ensuring the normal operation and long-term use of the flip assembly 30.

[0033] like Figure 2 and Figure 3 As shown, a plurality of assembly holes 320 are evenly spaced along the circumference of the turntable 32 , and the assembly holes 320 are used for correspondingly connecting to the tool magazine 40 .

[0034] The tool magazine 40 includes a bracket 41 connected to the turntable 32 and a tool magazine body 42 connected to the bracket 41; the tool magazine body 42 is used to correspond to the spindle 22 to achieve tool changing operation. Figure 4 As shown, the bracket 41 is evenly spaced with a plurality of through holes 410, and the through holes 410 correspond to the assembly holes 320 one by one. Bolts are passed through the through holes 410 and then screwed into the inside of the assembly holes 320, so that the bracket 41 and the turntable 32 can be matched and connected, so that the rotary cylinder 31 can drive the tool magazine body 42 to flip, as shown in FIG. Figure 5 As shown, after the tool magazine 40 is turned 180 degrees, the spindle box 22 and the spindle 23 are exposed for easy maintenance.

[0035] The above-mentioned dual-tool magazine machining center has a simple structure and is easy to use. Flipping assemblies 30 are respectively installed on the opposite sides of the optical machine 20. The rotary cylinder 31 is used to drive the tool magazine body 42 to flip to expose the spindle box 22 and the spindle 23, which is convenient for inspection and maintenance of the spindle 23, effectively improving the inspection efficiency and avoiding affecting the normal use of the machining center.
