Milling machine straight knot spindle quick disassembly mechanism

The creation of the milling machine directly to the spindle quick disassembly mechanism is mainly applied to the quick disassembly and assembly technology of the milling machine direct knot spindle.

According to the traditional method of belt drive milling machine spindle, because of the problems of vibration, noise and poor transmission efficiency, it is easy to rotate at high speed. As the machining precision is greatly improved, the rotation speed of the milling machine spindle is also getting faster and faster. The way of the belt-driven milling machine spindle has been replaced by the requirements of the times. The spindle of the milling machine is directly connected to the motor spindle through the coupling, the so-called straight-joint spindle.

The previous patent approval notice, application number: No. 090222335, Bulletin No.: No. 509127, "Parallel shrapnel mechanism for spindle loose broach", is a kind of straight-through spindle; mainly in: the spindle The main body has an axial receiving hole, a first receiving groove, and a second receiving groove. The mandrel has a spindle body that can be inserted into the receiving hole, and a mandrel is located at the end of the spindle body. a resisting member, a latch radially inserted between the first and second receiving slots and passing through the spindle body, and a cutter ring disposed on the latch, the spring mechanism having a first tandem And a second array of shrapnel sets, the first inline shrapnel set is disposed on the mandrel, and is received in the first receiving groove, the front end surface of which is abutted at the first a bottom wall of the accommodating groove, the other end surface abuts against the mandrel body, and the second in-line elastic piece set is also disposed on the mandrel body, and is accommodated in the second accommodating groove, one of the The end surface is abutted in one of the second receiving slots On the groove wall, the other end face abuts against the resisting member at the end of the mandrel body; however, when the elastic assembly of the shrapnel group needs to be replaced with a new shrapnel set, or the components are worn and need to be repaired, the manufacturer must rely on the manufacturer. Professionals can disassemble the components one by one, and then replace and repair each component. Local equipment maintenance personnel can not be installed, so it is necessary to return the entire spindle to the manufacturer for repair, which is time-consuming and labor-intensive, which in vain causes the entire working line to stop, affecting work efficiency, and the existing defects and problems that need to be solved.

The creator is currently engaged in the manufacture and design of related products, accumulated many years of practical experience and experience, and actively engaged in the spirit of innovation and improvement for the existing problems and lack of milling machines used in traditional milling machines, and completed a quick disassembly mechanism for a milling machine. .

The technical means applied by the new problem solving and the function of the prior art are as follows: a rotatable main shaft is arranged in the body, and a pull rod assembly is arranged inside the main shaft, and an actuating groove is arranged on the upper side of the main shaft for combining one dozen a knife ring, the knife ring is provided with a joint portion corresponding to the movement groove, so that the joint portion of the knife ring can be slipped in the movement groove, and a plurality of screw holes are arranged around the upper end portion of the spindle for locking a coupling member, the circumferential surface of the coupling member is corresponding to the screw hole of the main shaft, and a plurality of perforations are provided for the screw to be locked in the screw hole, and the coupling member is directly connected through the coupling On the motor spindle. When the elastic component is elastic and fatigued, it is necessary to replace the new elastic component, or the components are worn and need to be repaired. Only after removing several screws on the coupling member, the lever assembly can be quickly taken out and replaced with a new one. The assembly is very simple and convenient to operate. It is not necessary to send the whole spindle back to the manufacturer for repair. The local equipment maintenance personnel can disassemble, repair and replace the parts by themselves, which can achieve the effect of quick replacement and improve the efficiency. For its main purpose.
