The utility model discloses a kind of concave composite chamfering cutter, belong to machining tool design technical field, the composite chamfering cutter includes two center symmetrical cutter teeth, cutter tooth is composed of back rake face, oblique front and cylindrical arc surface, wherein: the included angle range of back rake face and vertical face is 35 ° to 50 °, the included angle range of oblique front and vertical face is 8 ° to 15 °, cylindrical arc surface is the extension of cylindrical cutter body, the top end of cutter tooth is also provided with tooth end face, the included angle range of tooth end face and horizontal plane is 3 ° to 8 °. Compared with prior art, the composite chamfering cutter carries out mirror image processing to the two blades of tool, and designs specific cutter tooth angle, and the oblique front of specific angle can effectively increase the strength of tool, facilitate chip removal, and the back rake face of specific degree can reduce the wear of cutting edge while reducing vibration;The stability and service life of tool are improved, and the overall tool can effectively reduce the vibration interference in the machining process during the machining process, to ensure the stability and consistency of machining quality.

This utility model relates to the field of metalworking cutting tool technology and discloses a composite arc-shaped end mill, including a cylindrical tool holder body and a connecting part. The connecting part is fixedly connected to the bottom inner wall of the cylindrical tool holder body. An adjustment mechanism is provided on the cylindrical tool holder body, and an auxiliary mechanism is provided on the adjustment mechanism. The adjustment mechanism includes a T-slot, which is formed on the top inner wall of the cylindrical tool holder body. A T-shaped bracket is slidably connected to the top inner wall of the T-slot, and an arc-shaped end mill is fixedly connected to the front outer wall of the T-shaped bracket. A threaded groove is formed on the top inner wall of the cylindrical tool holder body. In this utility model, through the cooperative design of the adjustment mechanism and the auxiliary mechanism, the quick disassembly and replacement of a single arc-shaped end mill is realized. When an end mill wears out, it is only necessary to pull the adjustment plate to release the limit and rotate the abutment plate to separate the clamping structure without disassembling the entire tool system.

The utility model provides intelligent household pear automatic peeling and dicing machine relates to fruit processing technical field, including equipment frame, the inside rear end position fixed mounting of equipment frame has the baffle frame, is provided with the guide frame A in the right upper position of baffle frame front end. After peeling, the turnover plate rotates right 90 degrees, the motor driver drives the rotary frame to rotate and contact the pear in left upper side, combines the driving motor and inserts the axle and drives the pear to rotate, can carry out the comprehensive horizontal cutting to the pear, makes the pear be even cut into the horizontal piece structure, the motor B driving shaft drives the progressive piece to slide back in the progressive frame, makes the rice character cylinder cutter move back and contact the pear and cut. Solveed the existing pear's peeling and dicing are implemented separately, cannot satisfy people's demand of fast access to the processed pear, and artificial cutting is difficult to guarantee that the size of each pear is even, the shape is regular, affects the problem of beautiful and taste.

The application discloses a design method of a whole type super-long time turning tool, an external circle continuous turning device and method, and relates to the technical field of special tool machining; solves the problem of local wear caused by the fixed contact point between the cutting edge and the workpiece when the traditional tool is used for continuously turning the external circle of a large long shaft workpiece; the application generates a continuous spiral renewal edge along the axis of the cylindrical tool body from the effective cutting section of the single point turning tool, and establishes a synchronous relationship among the spiral pitch, the tool rotation angular velocity and the axial compensation feed speed of the tool holder, so that the local edge section participating in the main cutting in the turning process keeps the spatial contact point with the workpiece basically localized, and the cutting edge material is continuously renewed along the spiral edge line; the application can disperse the wear and cutting heat to a longer continuous edge line without significantly changing the workpiece spindle speed and the conventional turning path, reduces the risk of local burning and collapsing of the edge, and is suitable for long time continuous external circle turning of large long shaft workpieces.
