Device and method for simultaneously machining multiple holes

Abstract

The invention relates to a device and method for simultaneously machining multiple holes. The device comprises a mechanical arm, a palm rest round plate, cutter feeding mechanisms, drilling and grinding integrated mechanisms, a drill bit and a profiling magnetic pole, wherein the palm rest round plate is fixed to the executing end of the mechanical arm, a plurality of tool feeding mechanisms are fixed to the palm rest round plate, the drilling and grinding integrated mechanisms are fixedly connected to the tool feeding mechanisms, each tool feeding mechanism comprises a round plate frame, a motor A and a four-connecting-rod mechanism, each four-connecting-rod mechanism is composed of two connecting rods and two rockers, the connecting rod 82, the connecting rod 82, the rocker 81 and the rocker 81 are sequentially hinged to form a rhombus structure, a drilling and grinding integrated mechanisms are connected to hinge points between the every tow connecting rods, the end parts of the rockers are connected to crank rocker mechanisms, one ends of the connecting rods are hinged to the rockers, the other ends of the connecting rods are hinged to one ends of cranks, and the other ends ofthe cranks are driven by the motor A to rotate. The device and method have the advantage that the device and method are suitable for drilling rough machining and grinding finish machining of holes which are regularly or irregularly distributed and have different hole diameters in the same surface.

Description

technical field [0001] The invention belongs to the field of hole processing, in particular to a device and method for simultaneously processing holes. Background technique [0002] With the continuous development of science and technology, more and more functions can be realized by the machine, and the complexity of the workpiece required is getting higher and higher. In order to save space and cost, enterprises are increasingly choosing non-standard parts as the first research and development. One option, the use of porous workpieces saves cost, saves space, and is easy to use, so porous workpieces are the most widely used in non-standard parts. [0003] However, with the wide application of porous parts, the shortage of porous workpiece processing technology in my country has also been exposed. At present, the hole processing technology for processing porous parts has relatively large shortcomings in terms of efficiency, standardization degree and hole precision. The mai...

Problems solved by technology

[0004] (1) Low drilling efficiency: With the wide application of porous parts, some processing devices and methods have appeared on the market for uniformly distributed pores, but for irregularly distributed pores on the same plane, single processing is often used The method is manually using a hand electric drill to open the hole, the efficiency of the hole is low, and the labor cost is high

[0005] (2) The standardization of holes is low: For the irregularly distributed pores on the surface of the workpiece, manual drilling is used. After drilling, there will often be inclinations, resulting in defects such as inclined holes and increased hole diameters. After processing, the easiest The accuracy of multiple holes on a workpiece is different, resulting in the inability to cooperate with each other

[0006] (3) The precision of the hole is too low, there are burrs, and it is easy to deform: In traditional processing, after drilling, the inner surface of the hole has low precision, and the machined surface of the hole has many burrs and low precision, but because the inner surface of the hole is not easy to grind, Therefore, for some holes that require high aperture precision, it is often impossible to meet its precision.

[0007] (4) It is impossible to work on a machine where the workpiece is not disassembled, and the flexibility is not enough: traditional processing methods can only be processed for workpieces in large areas or clamped on the machine tool, and for workpieces that are difficult to disassemble on some devices. often helpless
