[0002] A gearbox is a mechanical device that reduces input speed and increases output torque through transmission mechanisms such as gears and worm gears. It has functions such as power transmission, speed regulation, and load bearing, and is widely used in industrial equipment, robots, automobiles and other fields.

[0003] As the external structure of the gearbox, the gearbox housing needs to house internal components such as gears and bearings, and provide sealing, support, and heat dissipation functions. To meet the functional, maintenance, and safety requirements of the gearbox, the gearbox housing often needs multiple openings, such as mounting / fixing holes and sensor / electrical interface holes. Currently, drilling machines are commonly used to drill and tap the gearbox housing, which is time-consuming and labor-intensive, affecting not only processing efficiency but also requiring multiple clamping and positioning operations, thus impacting machining accuracy.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1 , 2 As shown, this utility model discloses a multi-axis drilling and tapping device, including a base 100, a feed module 200, a positioning module 300, a multi-axis machining module 400, and a cooling system 600.

[0027] The feed module 200 includes an X-axis linear module 210 and a Y-axis linear module 220. The positioning module 300 is fixedly mounted on the slider of the Y-axis linear module 220 and can perform horizontal reciprocating linear motion along the Y-axis. The Y-axis linear module 220 is fixedly mounted on the slider of the X-axis linear module 210 and can perform horizontal reciprocating linear motion along the X-axis. The X-axis linear module 210 is fixedly mounted on the upper surface of the base 100.

[0028] The positioning module 300 is driven by the X-axis linear module 210 and the Y-axis linear module 220, enabling precise displacement between the positioning module 300 and the workpiece 700. This moves the workpiece 700 to the corresponding multi-axis machining module 400 for processing, and adjusts the feed rate accordingly to ensure machining accuracy and stability. Both the X-axis linear module 210 and the Y-axis linear module 220 are dustproof linear modules to prevent debris generated during drilling and tapping from causing module jamming, vibration, or even damage, thus maintaining smooth feed motion. Furthermore, a cable chain 230 connects the X-axis linear module 210 and the machine base 100 to protect the equipment's wiring.

[0029] like Figure 3 , 4 As shown, the positioning module 300 includes a support platform 310, a positioning seat 320, and a pressing device 330. The support platform 310 is fixedly mounted on the slide of the Y-axis linear module 220 to support the workpiece 700. The positioning seat 320 is fixedly mounted on the support platform 310 and can abut against the side wall of the workpiece 700 to achieve positioning of the workpiece 700. At the same time, it assists the pressing device 330 in fixing the workpiece 700. The pressing device 330 is fixedly mounted on the support platform 310 to press and fix the workpiece 700.

[0030] The positioning seats 320 are provided in two or more locations, with at least two positioning seats 320 horizontally abutting against the side wall of the workpiece 700 in different directions. Together with the pressing device 330, they can constrain the workpiece 700 in multiple directions, making the clamping more stable and the positioning accuracy higher, which can provide a foundation for subsequent precision machining. Moreover, the clamping operation is convenient and can quickly adapt to workpieces 700 of different shapes and sizes, and is compatible with irregular or non-standard workpieces 700.

[0031] The positioning seat 320 comprises two parts: a positioning bolt 321 and an L-shaped seat body 322. Its overall size is small, requiring minimal space. The seat body 322 is fixed to the support platform 310, and the positioning bolt 321 is horizontally inserted into the seat body 322, with its end face facing the workpiece 700 to abut against it. By adjusting the degree of screwing in the positioning bolt 321, its end position can be changed accordingly, altering the positioning point and adapting to workpieces 700 of different shapes and sizes, thus improving the equipment's compatibility.

[0032] The pressing device 330, which plays a major fixing role, preferably adopts a rotary pressing cylinder, which can rotate and press the workpiece 700 to fix it. It is suitable for equipment with compact space and can avoid the workpiece 700 when picking up or putting down the workpiece 700, which is convenient for operation.

[0033] like Figure 5As shown, the multi-axis machining module 400 includes a servo motor 410 and a multi-axis actuator 420. The servo motor 410 is driven and connected to the multi-axis actuator 420. A drill bit 422 and / or a tap 423 are mounted on the output shaft 421 of the multi-axis actuator 420. The drill bit 422 and the tap 423 are installed and arranged according to actual machining requirements and processes. To facilitate feeding, an extension frame 500 is fixedly installed on the upper surface of the machine base 100. The multi-axis machining module 400 is fixedly mounted on the extension frame 500, so that the position and height of the output shaft 421 correspond to the workpiece 700. Under the precise transfer of the feed module 200, the multi-axis machining module 400 can perform multi-axis linkage machining, quickly and accurately performing drilling and tapping operations.

[0034] At least two multi-axis machining modules 400 are provided, with at least one multi-axis machining module 400 having its output shaft 421 arranged along the X-axis and at least one multi-axis machining module 400 having its output shaft 421 arranged along the Y-axis. These modules can work in conjunction with the feed module 200 to achieve multi-directional machining, improving machining efficiency and reducing the number of clamping operations during machining, thus reducing machining errors caused by multiple clamping and positioning. In this embodiment, the riser 500 is semi-enclosed around the feed module 200, and the multi-axis machining modules 400 are correspondingly divided into three groups and arranged around the three sides of the feed module 200, enabling three-directional machining of the workpiece 700.

[0035] The cooling system 600 includes a liquid inlet module (not shown), multiple liquid outlet pipes (not shown), and multiple solenoid control valves 610. The liquid inlet module includes a storage tank for coolant, a liquid pump providing power for liquid transport, and liquid inlet pipes for transmitting coolant. This module draws coolant and delivers it to each of the liquid outlet pipes. Solenoid control valves 610 are correspondingly installed on each liquid outlet pipe to control its opening and closing. Each liquid outlet pipe has a fluid distributor 620 connected to its output end. The fluid distributors 620 are correspondingly installed with the multi-spindle spindle 420, and their outlets are positioned above the corresponding drill bits 422 and taps 423.

[0036] By controlling the opening and closing of each electromagnetic control valve 610, the corresponding liquid outlet pipeline and fluid distributor 620 can be opened or closed, and the coolant can be guided to the multi-axis machining module 400 for processing, so as to cool, lubricate and remove chips from the corresponding drill bit 422 and tap 423.

[0037] In the cooling system 600, the electromagnetic control valve 610 adopts a volumetric hydraulic control solenoid valve, which has higher sealing performance and reliability, and stronger anti-contamination ability. The fluid distributor 620 includes a distribution pipe 621 and multiple outlet branch pipes 622. The distribution pipe 621 connects the outlet pipe and the outlet branch pipes 622. The outlet branch pipes 622 are arranged side by side, and the outlet of the outlet branch pipe 622 is located above the drill bit 422 and tap 423 mounted on each output shaft 421, which can guide the coolant to fully flush the drill bit 422 and tap 423.

[0038] In summary, this multi-axis drilling and tapping equipment has many advantages, such as high processing efficiency, good compatibility, and precise drilling and tapping capabilities.

[0039] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims are within the scope of protection of the present invention.
