Embodiment

[0031] like figure 1 and figure 2 As shown, the present invention provides a device specially used for processing non-circular holes through transformation of ordinary lathes. Using waste ordinary lathes, the device is fixed on the guide rail of the lathe through the pressing block 12, the fixing screw 13, and the base 14. The sheet group 11 adjusts the center of the central shaft transmission shaft 6 to be coaxial with the center of the lathe main shaft, and then connects the lathe main shaft and the central shaft transmission shaft 6 through the cross shaft and the coupling, as the power input of the device, and the device passes through the gear box part 2. The tool rest part 1 transmits the input power for machining.

[0032] like image 3 As shown, in the gear box part 2, the power and torque are transmitted from the central shaft 2-19 to the large gear 2-18, and the large gear 2-18 is fixed on the central shaft by the flat key 2-10 and the shaft end retaining ring 2-3...

Abstract

The invention relates to the technical field of mechanical processing, in particular to a device specially used for processing non-circular holes by using an ordinary lathe through modification. The device uses the main shaft of the lathe as the power input, and its speed can be adjusted by the speed regulating mechanism of the lathe itself. The power of the device comes from the main shaft of the ordinary lathe, and the power and torque are transmitted through the combination of the gear box and the tool holder of the device. Drive the three cutter heads in the tool holder combination to rotate synchronously to cut the workpiece, so that the tool can obtain the shape of the non-circular hole required by the part after one cut; during the cutting process, the coolant nozzle of the lathe is passed through The pipeline is connected to the device to cool the workpiece and cutting tool and take away the metal chips. The invention can obtain the shape of the internal non-circular hole of the parts to be processed through one processing, greatly reducing the difficulty of workers' operation, labor intensity and production cost, and at the same time improving production efficiency and product quality.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a device specially used for processing non-circular holes by using an ordinary lathe through modification. Background technique [0002] Ordinary lathes are equipment in which the workpiece rotates and the tool is fixed for processing. Boring is a machining process that uses the tool to rotate and the workpiece to be fixed, thereby boring the workpiece. [0003] Existing more commonly used machine tools for machining holes by boring mainly include drilling machines, boring machines and machining centers. [0004] Among them, the drilling machine mainly drives tools such as drill bits or taps by the spindle to perform drilling, reaming, reaming and tapping. The tool clamping method is mainly the friction fit between the inner cone surface of the Morse taper hole of the spindle and the outer cone surface of the tool Morse taper. For the processing of non-circular ho...
