Description

Technical Field

[0001] The invention relates to the technical field of drilling equipment, in particular to a multi-axis drilling and tapping tool for parts processing. Background Art

[0002] Drilling and tapping are common processing techniques for mechanical parts, and are a means of processing threaded holes. During processing, it is necessary to first use a drilling machine to drill holes in the mechanical parts, and then use tapping equipment to tap after drilling is completed. Therefore, two different sets of equipment are needed to complete the drilling and tapping processes. In order to solve this problem, the authorization announcement CN 211465455U proposes a tapping device for non-standard mechanical parts processing, including a supporting mechanism, a lifting mechanism, a processing mechanism, and an auxiliary mechanism. The lifting mechanism is provided on one side above the supporting mechanism, and the auxiliary mechanism is provided on one side of the lifting mechanism. The device can complete the positioning, drilling, and tapping tasks in sequence when the non-standard parts are clamped only once, which can not only improve production efficiency but also improve processing accuracy.

[0003] However, the above device still has certain defects in use. Although the device can complete drilling and tapping in one clamping, manual clamping and unloading are still required during processing, which is very time-consuming. At the same time, when in use, if there are multiple drilling positions on the same part, the existing technology can only be clamped by moving the fixture or readjusting the part position, which is very troublesome and difficult to apply to working conditions where multiple holes need to be drilled on the same part.

[0031] The profiling mechanism 6 includes several sliding rods 63, and several of the sliding rods 63 are fixedly connected in the hollow block 11 side by side.

[0035] A collecting box 3 is provided below the mounting opening 13 near one end of the tap 910 ; the collecting box 3 is used to collect the processed parts.

[0036] The working principle of the present invention is: when working, the position of the positioning column 61 is first adjusted according to the shape of the part, so that the positioning column 61 forms the outline of the part to position the part. When processing, the staff places the part in the outline formed by the positioning column 61, and then the hollow block 11 is sent to the bottom of the drill bit 907 under the intermittent conveyance of the synchronous conveyor belt 4. Then the positioning mechanism 8 positions the hollow block 11, and at the same time the fixing mechanism 7 fixes the part. Then the second servo motor 904 drives the drill bit 907 to rotate, and at the same time the third screw module 903 drives the second servo motor 904 to descend to realize drilling of the part. When it is necessary to drill holes in different positions of the part, the first screw module 901 can drive the second servo motor 904 to move on the X-axis, and the set second screw module 908 can drive the second servo motor 904 to move on the Y-axis, thereby realizing the adjustment of the position of the second servo motor 904 and realizing drilling of different positions of the part. After the drilling is completed, the positioning mechanism 8 and the fixing mechanism 7 are reset, and then the hollow block 11 moves to the position below the tap 910 under the intermittent conveyance of the synchronous conveyor belt 4. After reaching the position, the positioning mechanism 8 and the fixing mechanism 7 are activated again, and then the corresponding second servo motor 904 is started to drive the tap 910 to rotate. At the same time, the corresponding third screw module 903 pushes the second servo motor 904 downward at a set speed according to the speed of the second servo motor 904, so that the drilled hole can be tapped. Similarly, the tap 910 can also be moved in the X-axis and Y-axis directions under the drive of the corresponding first screw module 901 and the second screw module 908, so as to realize tapping of holes at different positions on the part. After the tapping is completed, the positioning mechanism 8 and the fixing mechanism 7 are reset, and then the hollow block 11 moves to the lower end belt surface under the intermittent conveyance of the synchronous conveyor belt 4, and then the part falls into the collection box 3 under the action of gravity, thereby completing the drilling and tapping of the part.

For the electronic control method and control program of each electronic control component, personnel in this technical field can implement simple programming according to actual processing requirements, which will not be elaborated here.
