Description

Technical Field

[0001] The utility model relates to the technical field of machining equipment, in particular to a full-automatic multi-position multi-hole drilling and tapping integrated machine. Background Art

[0002] In industrial production, it is often necessary to drill holes in workpieces, especially some workpieces that need to be drilled and tapped at the same time. At present, production is mainly based on manual work, that is, operators use drilling machines and tapping machines, assisted by simple clamps to complete the processing of drilling step holes, chamfering step holes, drilling two threaded bottom holes, and tapping two screw threads. At the same time, in order to perform the two processes of drilling and tapping, it is necessary to first use a drilling machine to drill holes, and then use a tapping machine to tap. Therefore, the workpiece needs to flow through these two processing procedures, and the workpiece transfer operation needs to be performed, which makes the drilling and tapping operations of the workpiece more time-consuming and inefficient.

[0003] Based on manual work, there are the following problems: 1. High labor intensity; when the order volume is large, workers need to work overtime and the working hours are long. Because of the constant movement of hands and feet, workers are often exhausted. 2. There is a certain degree of danger in the work; because the work is done manually, there will be close contact between the workers' hands and mold tools or deep into the mold, and safety accidents may occur when the workers are tired. 3. Quality is difficult to guarantee; due to manual operation, the quality is controlled by human beings, and workers are often rotated. New workers do not fully understand the quality requirements, which will cause certain quality deviations. 4. Even if high-precision machine tools used in CNC numerical control processing are used for processing, although the quality can be guaranteed, the workers' labor intensity is still very high because workers are also used to operate the loading and unloading work.

[0063] The fully automatic multi-position multi-hole drilling and tapping machine provided in this embodiment specifically works as follows:

[0064] The fully automatic multi-position multi-hole drilling and tapping machine places the cut guide rail base 9 into multiple material channels 11 of the material preparation rack group 1, and drives the screw rod 15 through the servo power to slide the guide rail base 9 in the material channel 11 into the loading station 2 of the machine in sequence.

[0065] The loading position 52 is grasped by the clamp and the guide rail base 9 is transported to the position where the corresponding air gripper of the material transfer group 5 can grasp it. The material transfer group 5 moves linearly along the transport guide rail 51 through the cylinder, and grasps the guide rail base 9 on the clamp through the first air gripper 53 and the second air gripper 54, and transfers the guide rail base 9 on the loading station 2 to the next station.

[0066] The guide rail base 9 is grabbed by the pneumatic claw of the material transfer group 5 from the loading station 2 to the step hole drilling station 31, and the step drill 311 is driven by the double servo power head to rotate and feed, and withdraws after the step hole requirement is met.

[0067] The guide rail base 9 is continuously transferred by the material transfer group 5 to the next reverse chamfering station 32. The reverse chamfering station 32 is powered by a special drilling machine head, and the reverse edge of the processed step hole is chamfered by a chamfering drill 321. It should be noted that when the guide rail base 9 is grasped by the first air gripper 53 and the second air gripper 54 in the material transfer group 5 and the material is loaded to the next station, when the first air gripper 53 and the second air gripper 54 do not grasp, the guide rail base 9 is clamped on the tooling 71 with the I-shaped limit table 72 on the tooling 71 and the process clamping group 7 to wait for the grasping of the air gripper.

[0068] The guide rail base 9 is continuously transferred by the material transfer group 5 to the next step hole detection station 33. The step hole detection station 33 uses the principle of photoelectric reflection to detect whether the step hole is drilled through by the reflection photoelectric switch 331. This detection can detect whether the step hole is penetrated and whether the step drill 311 head is broken. The reflection photoelectric switch 331 is fixed on the process clamping group 7 corresponding to the step hole detection station 33. Specifically, the reflection photoelectric switch 331 is fixed on the clamping member 74, and the reflection photoelectric switch 331 is aligned with the hole center of the step hole.

[0069] The guide rail base 9 is continuously transferred by the material transfer group 5 to the next threaded hole drilling station 41. At the threaded hole drilling station 41, the clamping cylinder 73 on the process clamping group 7 drives the clamping member 74 to clamp the guide rail base 9 onto the tooling 71 of the station, and a special drilling power head is used to provide power to drive the two-axis device to use a drill bit to drill two threaded bottom holes. The two-axis device controls the spacing between the two holes, and the depth adjustment of the power head controls the depth of the hole.

[0070] The guide rail base 9 is continuously transferred by the material transfer group 5 to the next drilling inspection station 42. At the drilling inspection station 42, the pressing cylinder 73 on the process pressing group 7 drives the pressing member 74 to press the guide rail base 9 onto the tooling 71 of the station, and the cylinder drives two hollow round rods 423 to be inserted into the thread bottom hole to detect whether the thread bottom hole reaches the depth required by the drawing. At the same time, the hollow round rods 423 blow high-pressure air into the hole to blow out the debris in the hole, so as to facilitate the next tapping process.

[0071] The guide rail base 9 is continuously transferred by the material transfer group 5 to the next tapping station 43. At the tapping station 43, the clamping cylinder 73 on the process clamping group 7 drives the clamping member 74 to clamp the guide rail base 9 onto the tooling 71 of the station, and a dedicated servo tapping power head is used to provide power to drive the two-axis device to perform thread tapping. The two-axis device controls the hole spacing, and the tapping depth is controlled by the depth adjustment of the power head.

[0072] The guide rail base 9 is continuously transferred by the material transfer group 5 to the next tapping detection station 44. At the tapping detection station 44, the pressing cylinder 73 on the process pressing group 7 drives the pressing member 74 to press the guide rail base 9 onto the tooling 71 of the station, and the cylinder drives two hollow round rods 423 to be inserted into the threaded hole to detect whether the tap is broken in the hole. At the same time, the hollow round rod 423 blows high-pressure air into the hole to blow out the debris in the hole.

[0073] The guide rail base 9 is continuously transferred to the next blanking station by the material transfer group 5. After the guide rail base 9 reaches the position at the blanking station, the first air gripper 53 and the second air gripper 54 are released and the material is blown down into the blanking trough 62 with high-pressure air. In this way, all the processes of drilling the step hole, chamfering the reverse side, drilling two holes, and tapping two teeth of the guide rail base 9 are completed.

[0074] While drilling step holes, chamfering the reverse side, drilling 2 holes, and tapping 2 threads, the water pump on the water tank sprays cooling water onto the tool that needs cooling and lubrication to perform cooling and lubrication work during processing. It can also cool the high temperature generated by the workpiece during processing.

[0075] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
