4results about How to "Quick tool change" patented technology

The utility model provides a kind of quick tool changing structure of galvanized sheet bar shearing machine, comprising: main body frame, the inside of the main body frame is provided with several mutually inserted tool bit structure, the tool bit structure includes the tool holder slidingly connected in the inside of main body frame, the bottom of the tool holder is fixedly connected with shear tool bit.The utility model is provided with multiple tool bit structure in the inside of main body frame, when tool bit wears and needs to be replaced, can control electric telescopic rod to make it stretch, to remove the fixation of the lowermost tool bit structure, the lowermost tool bit structure is affected by gravity and slides down, each tool bit structure in the upper loses support and slides down synchronously, then start servo motor, make baffle rotate 180 degrees, baffle is far from the bottom end of guide rod, worn tool bit structure loses support, falls from the bottom of main body frame, so as to reach the effect of quick tool changing, keep tool bit precision, improve shearing efficiency and quality, facilitate user to use.

The present application relates to a five-axis three-dimensional printing device, which comprises a bed assembly, a protection mechanism, a printing library and a moving mechanism, the bed assembly comprises a base, a rotary table and a plurality of heat insulation plates, the rotary table and the heat insulation plates are both arranged on the base; the plurality of heat insulation plates enclose a processing cavity, a rotating arm of the rotary table is arranged in the processing cavity; the protection mechanism is arranged above the processing cavity, the protection mechanism is provided with a retractable door for closing or opening the processing cavity; the printing library is arranged outside the processing cavity; the printing library is provided with a printing head; the moving mechanism is arranged outside the processing cavity, and the moving mechanism comprises a zero-point clamp for clamping the printing head; the zero-point clamp is movably arranged above the retractable door; wherein, when in a processing state, the retractable door opens the processing cavity to allow the zero-point clamp to drive the printing head into the processing cavity; when in a reloading state, the retractable door closes the processing cavity, and the printing head and the zero-point clamp are outside the processing cavity. The present application realizes high-precision printing of a small five-axis device.

The utility model discloses a quick tool changer convenient to motor part processing, including main tool body, the both ends of rotator set up blade groove, and the turning blade is fixed in the blade groove through locking screw, the cylinder of rotator bottom and the hole clearance cooperation in tool cushion and main tool body, and main tool body sets up cylinder jacks, and the cylinder of rotator bottom and cylinder jacks abut, and are locked through the bolt of main tool body outside, the below of rotator is equipped with the key, and is in touch positioning with the keyway of tool cushion plane, and the inside of main tool body includes the upper spout pipe of main tool body upper portion and the lower spout of front end, the utility model has the advantages that: reduce production cost and improve processing efficiency, the internal cooling device in main tool body sprays coolant to cutting edge through upper spout pipe and lower spout, solves the processing overheating problem, improves cutting performance, can use high pressure cooling water to wash away the chip, solves long chip problem, and the rotator with positioning key can realize quick tool changing function.

A multi-edged shallow-groove cutting tool includes a cutting tool and further includes: a tool holder with a "W"-shaped semi-open insert holder at one end; a fixing assembly including a fastening screw and an "L"-shaped pressure plate; a cutting insert mounted on the insert holder via the fixing assembly, the cutting insert comprising multiple cutting edges; multiple positioning bosses evenly distributed on the first surface of the insert holder, and at least two through screw holes on the insert holder; a positioning groove matching the positioning bosses at the bottom of the cutting insert, and a through hole corresponding to the screw holes on the cutting insert; this utility model has a novel structure, and through the double fixing of screws and "L"-shaped pressure plates, the double fixing mechanism (screw pre-tightening + pressure plate pressure) combined with a multi-level support structure, it can withstand axial cutting forces of over 500N, with insert offset ≤0.02mm.
