Technical field
The utility model relates generally to the tool-broaching mechanism in a kind of Digit Control Machine Tool main power plant, is mainly used in the milling of large and medium-sized part, bores, attacks, the Roughing and fine machining such as boring, endoporus, cylindrical, plane, step, the conical surface, sphere, groove.
Background technology
Along with electric wire industrial expansion both domestic and external, the user is increasing to the demand of electric wire manufacturing equipment, required precision to equipment is also more and more higher, if the original process equipment working ability of company is not enough, processing charges is high and process outward not only, and the process-cycle is long, has a strong impact on the raising of production efficiency, delivery cycle and the production capacity of company, makes company suffer many losses in interests and prestige.Particularly in recent years in the new high-tech product, required precision to product is higher, Φ 400/48 dish cage winch, Φ 610/6+12+18 cage winch (separated motor, the control of laying tension magnetic hysteresis) etc., the large or complex structure of capstan winch on these equipment, dimension precision requirement is high, outer processing difficulty, cycle is long, and in the market, does not meet the tool-broaching mechanism about the special-purpose large-sized gantry digital-control boring-milling machine of this type of part processing.
The utility model content
The purpose of this utility model is in order to remedy the deficiency of prior art, tool-broaching mechanism in a kind of Digit Control Machine Tool main power plant is provided, be used for finishing the milling of large and medium-sized part, bore, attack, the work termination of the Roughing and fine machining of boring, endoporus, cylindrical, plane, step, the conical surface, sphere, groove etc., whether it easy to the installation of machine tool, whether clamp whether firm and tool changing simply requires very high, it directly has influence on the positioning accuracy of cutter, is tool-broaching mechanism novel, efficient, the technological innovation type.
The utility model is achieved through the following technical solutions:
Tool-broaching mechanism in a kind of Digit Control Machine Tool main power plant, include main shaft, cylinder, butterfly spring, pull bar, upper blind rivet, the blind rivet handgrip, the blind rivet cover, the taper tool shanks of lower blind rivet is housed, it is characterized in that: have pull bar to pass in the described main shaft, described pull bar upper end is set with butterfly spring, and butterfly spring is installed in the stepped hole of main shaft upper end, the pull bar of described butterfly spring upper end is provided with fixed cover, the stepped hole of described fixed cover and main shaft upper end is slidingly matched, the lower end of described pull bar is installed with blind rivet, the bottom of described upper blind rivet is installed with blind rivet cover and the blind rivet handgrip that cooperatively interacts, described blind rivet handgrip below is provided with the taper tool shanks that lower blind rivet is housed, when described blind rivet handgrip tightens up and lower blind rivet clamp, cylinder has been set up in the top of described upper blind rivet, and with the cylinder piston rod corresponding matching.
Described blind rivet handgrip symmetry division becomes four parts, and the inner chamber of corresponding main shaft is conical cavity with it, and the deadweight because of cutter when pneumatic tool changing of described blind rivet handgrip is opened automatically.
Its principle is: main shaft is the major part of tool-broaching mechanism, special inner-cavity structure, make the pull bar, blind rivet handgrip, blind rivet cover and the cutter that are installed in the main shaft lumen orifice can finish specific action, the Latin handgrip can press down in main shaft inside and open and put forward closure, along with moving, pull bar finishes pneumatic tool changing action, and the taper hole that precision and cooperation is required high mounting cutter.Because to the high request of intensity, wearability, fatigue limit etc., so main shaft employing structural alloy steel, heat treatment mode is modifier treatment, and the end surfaces of that end of mounting cutter is carried out the nitriding processing.
Blind rivet handgrip and blind rivet cover are the key parts in addition of loading and unloading cutter, can adopt cylinder to depress, the blind rivet handgrip unclamps lower blind rivet, realize the tool changing function, also can satisfy the pulling force that utilizes butterfly spring, make and move promptly taper tool shanks and upwards tension on the blind rivet handgrip, realize the automatic tool-broaching function, the project organization that this is special has guaranteed the reliable and stable of action.
Butterfly spring is the critical piece of finishing the machine automatization broaching tool in the tool-broaching mechanism, it is by the characteristic of self, after pneumatic compression power disappears, when recovering original shape to pulling force that makes progress of pull bar, make the blind rivet handgrip firmly grasp taper tool shanks and upwards tension, automatically finish the broaching tool action.Simultaneously, it also plays the function that relaxes impact and vibration damping when pneumatic tool changing.
The utility model has the advantages that:
The utility model reasonable in design can satisfy the gentle functional requirement of moving cutter of machine automatization broaching tool, has very high positioning accuracy, improves equipment performance and reliability, has originality, advance.
