New description: [New technical field] This creation is related to the processing spindle group. In more detail, it refers to a processing spindle group with an electrical conduction device. The electrical connection between the main shaft seat and the electrical components can be achieved, and the rotary mandrel and the tool holder are not subject to tool change or rotation. [Prior Art] ^ A conventional machining spindle set as shown in the first drawing, which mainly comprises: a main_axis 1, the main shaft 1 includes a - spindle seat 2 and - can be placed on the main Rotating mandrel 3 within 2. The end of the rotating mandrel 3 is concavely provided with a taper hole 4. A broach assembly 5 is provided in the tapered bore 4. And at least one knife handle 6 movably secured within the tapered bore 4. The knife handle member 6 is provided with a broach shaft 7 which can be movably coupled with the broach assembly 5, and a stalk portion 8 which can be attached to the horn-like taper section 8, _ with the job rotation, 3 is fitted with the rotation shaft 5 The other end is coupled to a motor ' to rotate the rotary spindle 3 and the handle member 6 for the _plus 4 action. Since the tool holder 6 can be quickly replaced with the tool magazine to meet the needs of the machining process, the machining spindle set is widely used in various automatic machining machines. However, the processing is performed by simply using the tool holder 6 itself to have a tool hardness higher than that of the workpiece. However, the hardness of the workpiece is too high, which may cause the blade member 6 to quickly wear and damage. And such as high-hardness and fragile materials such as broken glass, it is easier to produce cracks in the processing area. Therefore, a conventional technique disclosed in the "Ultraphone Processing Machine" of No. 49 of the Republic of China Patent No. 49 is equipped with a machining head (knife handle member) at the tip end of the spindle, and the machining head is provided with a tool for generating super The ultrasonic vibrator for sonic vibration, by cutting and grinding the tool with high-frequency vibration of the tool, can greatly reduce the wear caused by the tool for the machining of high-hardness workpieces, and can prevent the fragile workpiece from being exhausted. . However, the technique disclosed therein is to provide a verification joint at the main shaft of the outer periphery of the processing head, and the electric rotary joint is used to introduce the power into the processed ultrasonic vibrator. In this way, in addition to the fact that the electrical rotary joint easily affects the tool change operation of the machining head, since the electric rotary joint is exposed outside the spindle seat, if the user improperly controls, the accident of collision damage is more likely to occur. Another conventional technique, such as the Republic of China Patent No. M400930, "Electrical Conduction Device for Ultrasonic Spindles", is an electrical transfer device for an ultrasonic spindle. The utility model is characterized in that the broach shaft of the knife handle member and the jaw seat of the pull 77 assembly are respectively provided with an electric hard head, and the clamp claw seat and the connected claw shaft are respectively provided with a power supply lead group to be connected to the main shaft. The other end of the power supply. This allows the power supply to be conducted to the ultrasonic oscillator in the tool holder. This way, the electrical conduction device is placed in the spindle. p ‘ avoids the problem of affecting tool change and collision. However, when the spindle group is changed, the cutter wheel will move the claw seat to push the top and hit the broach shaft to facilitate the exit of the knife handle. In addition, the power connector is easily damaged by the collision. Furthermore, the position of the power connector and the power cord set is 'the position of the central water outlet circuit of the cutting fluid of the spindle group, which may cause the problem that the main wheel set cannot be installed with the central water outlet loop, and the practicality is lacking. In addition, in order to accurately control the wear or change of the tool during the machining process, as disclosed in the second (No. 1961 "Tool machine spindle structure that can monitor the working state immediately", there is an internal detecting device in the tool holder to measure the machining process. The various tool working parameters are transmitted from the wireless transmission module in the internal detecting device to the external device, so as to accurately and instantly perform the operation of the tool_. However, if each tool holder is set to detect and The wireless transmission function _ part detection device, in addition to causing a significant increase in manufacturing costs, because the main shaft, the tool holder and the machine are all made of metal 'is easy to produce wireless signal shielding effect. Therefore, a low cost, electrical signal transmission effect is required. Electrical transmission device. [New content] Comprehensively open the shortcomings of the prior art, generally including the conventional electrical conduction device, except for the structural appearance (4) the tool change action of the knife blade, the collision damage and the existing spindle group structure and Wei and other defects.

The main purpose is that, by the above-mentioned electrical conduction device, when the blade holder is fixed to the taper hole (10), the material contact is in contact with the miscellaneous conductive member, so that the spindle seat and the electric milk 7L are electrically connected together. It does not hinder the rotation of the shaft and the tool holder. The secondary purpose of this creation is that the electrical conduction device is a built-in structural design, except that it does not interfere with the tool change action, and its structure is more It does not affect the structure and function of the existing spindle group, and still retains the well-known design of the central water outlet. The other secondary purpose of the creation is that the electrical conduction device is a wired structure design. 'The wireless transmission module can be transmitted to the outside without using a wireless transmission module. The device can effectively reduce the transmission cost of the signal, and the effect of the Wei-Xi fresh is reduced. The advantages of rhyme.
