It plays a central role in machining operations, particularly in lathes, milling machines, and drilling machines. The main functions of the spindle box are to transmit power, control the spindle's rotational speed, and provide a stable working platform for the workpiece or tool. The spindle box primarily consists of the spindle, gear transmission system, bearing system, motor, gear shift mechanism, lubrication system, and cooling system. The spindle is the most important component within the spindle box, directly driving the workpiece or tool's rotation. The cross-spindle head is a spindle assembly with a unique structure. It is widely used in multi-axis machining equipment, particularly in milling-turn machining centers, for complex machining operations. Its spindle structure consists of a vertical spindle and a horizontal spindle, respectively, capable of driving the tool or workpiece for vertical and horizontal rotational machining operations. Its unique design allows the spindle to rotate in different directions, accommodating multi-angle machining needs.

[0003] However, the existing cross spindle head is usually fixedly installed inside the box, and its installation, disassembly, maintenance and use flexibility are limited, making it inconvenient for operators to adaptively adjust the spindle box according to actual production conditions, and some split spindle heads have insufficient connection strength.

[0027] See also Figures 1 to 2The present invention discloses a detachable spindle box 10, which includes a box body 100, a first shaft body 200, and a second shaft body 300. The first shaft body 200 and the second shaft body 300 are both installed inside the box body 100; wherein the box body 100 is provided with a first installation cavity 110 and a second installation cavity 120 extending perpendicularly to each other. Correspondingly, the first shaft body 200 is embedded and installed inside the first installation cavity 110, and the second shaft body 300 is embedded and installed inside the second installation cavity 120, so that the first shaft body 200 and the second shaft body 300 are arranged perpendicular to each other, thereby forming a cross spindle box structure. Specifically, the first shaft body 200 and the first installation cavity 110 are detachably connected; the second shaft body 300 and the second installation cavity 120 are detachably connected. In a traditional cross-shaped spindle box, the main bodies of the two spindles arranged perpendicular to each other are usually fixedly connected to the box body 100 in an integrally formed manner. However, the first axis 200 and the second axis 300 of the utility model can be independently installed, disassembled, repaired and replaced according to the actual use of the equipment, thereby greatly improving the convenience and flexibility of use of the detachable spindle box 10 of the utility model.

[0028] Furthermore, the first shaft 200 includes a first mounting portion 210 and two first connecting portions 220, which are respectively provided at both ends of the first mounting portion 210 to realize the main shaft connection drive function; when the first shaft 200 is installed in the first mounting cavity 110, the first mounting portion 210 is accommodated in the first mounting cavity 110, thereby realizing a detachable connection between the first shaft 200 and the first mounting cavity 110. Specifically, the first mounting cavity 110 is configured as a cylindrical structure, and correspondingly, the first mounting portion 210 is configured as a columnar structure, and the inner wall surface of the first mounting portion 210 corresponds to the side surface of the first mounting portion 210, thereby ensuring the installation stability of the first shaft 200 between the first mounting cavity 110.

[0029] Furthermore, the second shaft body 300 includes a second mounting portion 310 and two second connecting portions 320, which are respectively provided at both ends of the second mounting portion 310 to realize the main shaft connection drive function; when the second shaft body 300 is installed in the second mounting cavity 120, the second mounting portion 310 is accommodated in the second mounting cavity 120, thereby realizing a detachable connection between the second shaft body 300 and the second mounting cavity 120. Specifically, the second mounting cavity 120 is configured as a cylindrical structure, and correspondingly, the second mounting portion 310 is configured as a columnar structure. The inner wall surface of the second mounting portion 310 corresponds to the side surface of the second mounting portion 310, thereby ensuring the installation stability of the second shaft body 300 between the second mounting cavity 120.

[0030] Furthermore, the first shaft 200 includes two first covers 230, which are respectively mounted on both ends of the first mounting portion 210. When the first mounting portion 210 is inserted into the first mounting cavity 110, the two first covers 230 cooperate to connect to the end surfaces of the first mounting cavity 110, thereby sealing the first mounting cavity 110 and ensuring the independence of the interior of the first mounting cavity 110. Specifically, one of the first covers 230 is provided with a first air pipe connector 240, which is connected to the interior of the first mounting cavity 110 through the corresponding first cover 230, so that the first mounting cavity 110 can be connected to an external air source. In one embodiment, one of the first covers 230 and the first shaft 200 are fixedly connected by integral molding, thereby strengthening the connection strength between the first cover 230 and the first shaft 200, thereby improving the connection strength between the first cover 230 and the first shaft 200 and the housing 100.

[0031] Furthermore, the second shaft 300 includes two second covers 330, which are respectively mounted on both ends of the second mounting portion 310. When the second mounting portion 310 is inserted into the second mounting cavity 120, the two second covers 330 are connected to the end surfaces of the second mounting cavity 120, thereby sealing the second mounting cavity 120 and ensuring the independence of the interior of the second mounting cavity 120. Specifically, one of the second covers 330 is provided with a second air pipe connector 340, which is connected to the interior of the second mounting cavity 120 through the corresponding second cover 330, so that the second mounting cavity 120 can be connected to an external air source.

[0032] Furthermore, each first cover 230 also includes two first limiting members 250, which respectively cooperate with the two ends of the corresponding first cover 230 and are connected to the box body 100. Therefore, the two first limiting members 250 can further limit the connection stability between the corresponding first cover 230 and the box body 100, and reduce the damage to the wall of the box body 100 caused by the torsion between the two.

[0033] Furthermore, each second cover 330 also includes two second limiting members 350, which respectively cooperate with the two ends of the corresponding second cover 330 and are connected to the box body 100. Therefore, the two second limiting members 350 can further limit the connection stability between the corresponding second cover 330 and the box body 100, and reduce the damage to the wall of the box body 100 caused by the torsion between the two.

[0034] In summary, the detachable spindle box disclosed in the present invention is installed in the first mounting cavity by means of a first shaft body, and the second shaft body is installed in the second mounting cavity by means of a second shaft body, so that the first shaft body and the second shaft body are arranged perpendicular to each other, thereby forming a cross spindle box structure. A detachable connection is adopted between the first shaft body and the first mounting cavity; a detachable connection is adopted between the second shaft body and the second mounting cavity. In a traditional cross-type spindle box, the main bodies of the two spindles arranged perpendicular to each other are usually fixedly connected to the box body in an integrally formed manner, while the first shaft body and the second shaft body of the present invention can be independently installed, disassembled, repaired and replaced according to the actual use of the equipment, thereby greatly improving the convenience and flexibility of use of the detachable spindle box of the present invention.
