Description

Technical Field

[0001] The utility model relates to the technical field of machining equipment, and specifically, to a tapping and drilling integrated device. Background Art

[0002] Currently, when machining threaded holes on workpieces, a drill bit is first used to drill a hole as a bottom hole, and then a tap is used to machine an internal thread on the basis of the bottom hole. For a single workpiece, usually a drill press is used for drilling operations, and then the drill bit is replaced with a tap for tapping operations; for a large number of workpieces, usually a drill press is used for drilling operations, and then the drilled workpieces are transported to another drill press for tapping operations.

[0003] The above technical solutions have the following disadvantages: the workpieces need to be transported between multiple devices, resulting in low production efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a tapping and drilling integrated device for the above problems, which can continuously perform tapping and drilling to improve production efficiency.

[0005] To achieve the above purpose, the utility model discloses a tapping and drilling integrated device, which includes a workbench. A turntable is rotatably connected to the upper part of the workbench. A drilling equipment assembly and a tapping equipment assembly are also installed on the upper part of the workbench. A plurality of workpiece placement platforms arranged along its circumferential direction are installed on the upper part of the turntable. A pneumatic fixture is installed on the workpiece placement platform. A vertically arranged air inlet cylinder with both upper and lower ends closed is installed at the axis of the turntable. The air inlet cylinder is connected to the pneumatic fixture through a fixture control valve. The lower end of the air inlet cylinder is connected to a gas supply device through a rotary joint.

[0006] During use, in step one, a workpiece is placed on the first workpiece placement platform, and the pneumatic fixture fixes the workpiece; in step two, the turntable rotates to rotate the first workpiece placement platform to the position of the drilling equipment assembly for drilling. At the same time, a workpiece is placed on the second workpiece placement platform, and the pneumatic fixture fixes the workpiece; the turntable rotates to rotate the first workpiece placement platform to the tapping equipment assembly for tapping, and rotates the second workpiece placement platform to the position of the drilling equipment assembly for drilling. At the same time, a workpiece is placed on the third workpiece placement platform, and the pneumatic fixture fixes the workpiece. In this way, tapping and drilling can be continuously performed, and the production efficiency is high.

[0007] Preferably, an air pipe support is installed on the workbench. The air inlet cylinder is rotatably connected to the air pipe support. An air inlet pipe is connected between the rotary joint and the gas supply device, and the air inlet pipe is fixedly connected to the air pipe support.

[0008] During use, the air pipe support further limits the air inlet cylinder to ensure the stability of the rotation of the air inlet cylinder, which is beneficial for the gas supply device to supply gas to the air inlet cylinder through the rotary joint.

[0009] Preferably, an air cylinder bearing is installed between the air intake cylinder and the air pipe bracket.

[0010] During use, the air pipe bracket further limits the air intake cylinder to ensure the stability of the rotation of the air intake cylinder, which is beneficial for the air supply device to supply air to the air intake cylinder through the rotary joint.

[0011] Preferably, an exhaust cylinder is installed inside the air intake cylinder. Both the upper and lower ends of the exhaust cylinder pass through the air intake cylinder, and the exhaust cylinder is connected to the pneumatic fixture through a clamp control valve.

[0012] During use, the exhaust of the pneumatic fixture is discharged to the lower part through the exhaust cylinder, reducing the influence of the air flow on the equipment above the workbench.

[0013] Preferably, a rotary cylinder is connected to the lower part of the turntable. A gear ring is installed at the lower end of the rotary cylinder. A motor is installed on the workbench, and the output end of the motor is connected to the gear ring through a transmission gear set.

[0014] This structure is simple, with low manufacturing cost. At the same time, the control of the turntable is accurate.

[0015] Preferably, a turntable bearing is installed between the turntable and the workbench.

[0016] During use, the stability of the rotation of the turntable is ensured.

[0017] Preferably, the upper part of the workbench has a turntable seat protruding from the upper surface of the workbench. The shape of the turntable seat is annular, and the rotary cylinder passes through the turntable seat.

[0018] During use, the turntable seat is higher than the upper surface of the workbench, reducing the risk of dirt on the upper surface of the workbench entering the connection between the rotary cylinder and the workbench.

[0019] Preferably, the number of workpiece placement platforms on one turntable is at least four.

[0020] Among them, the four workpiece placement platforms respectively correspond to the first, second, third, and fourth positions of the workbench. When starting, the first position is the workpiece placement position, the second position is the drilling position, the third position is the tapping position, and the fourth position is the workpiece disassembly position.

[0021] In summary, the beneficial effects of the present utility model are as follows: During use, in step one, a workpiece is placed on the first workpiece placement platform, and the pneumatic fixture fixes the workpiece; in step two, the turntable rotates to rotate the first workpiece placement platform to the position of the drilling equipment assembly for drilling. At the same time, a workpiece is placed on the second workpiece placement platform, and the pneumatic fixture fixes the workpiece; the turntable rotates to rotate the first workpiece placement platform to the tapping equipment assembly for tapping, and rotates the second workpiece placement platform to the position of the drilling equipment assembly for drilling. At the same time, a workpiece is placed on the third workpiece placement platform, and the pneumatic fixture fixes the workpiece. By circulating in this way, tapping and drilling can be continuously carried out, and the production efficiency is high. Brief Description of the Drawings
