Description

Ultrasonic assisted machining sensing and transmission system

The present invention relates to an ultrasonic assisted machining system, and more particularly to an ultrasonic assisted machining sensing and transmission system.

The general ultrasonic auxiliary processing machine is based on the characteristics of the piezoelectric material for high-frequency vibration, wherein the piezoelectric material requires the conduction of electric power, and thus the conductive design is inevitably involved. Basically, the conductive method uses a brush or a wire to transmit power to the piezoelectric material, such as the ultrasonic auxiliary processing machine of CN 102989653A, which is electrically conductive by the contact of the brush and the conductive ring, but must be encountered. The problem of rotational wear of brushes and conductive parts; for example, the ultrasonic assisted processing machine of US 20110155407A1, which has multiple sets of gears and wire structures inside, which may cause internal components of wires and processing machines during the rotating process. Wreaking and posing a danger.

In addition, in order to provide processing accuracy, the ultrasonic auxiliary processing machine also establishes a feedback mechanism of the electronic signal to provide higher tool processing accuracy, such as sensing the current or potential difference transmitted to the piezoelectric material by coil induction. This is used as a feedback signal to adjust the predetermined current, but this method is susceptible to interference from external power supply noise (such as mains, motor current, and current driving the vibrator). There are other influencing factors in practice. This includes the difference in the weight of the driving load, the difference in the resonant mode, etc., so that the sensed current cannot be analyzed in a simple linear manner.

Therefore, in order to solve the above problems, it is necessary to improve the structural design and the processing feedback mechanism of the ultrasonic auxiliary machining machine rotating and simultaneously vibrating.

The primary object of the present invention is to provide an ultrasonic assisted machining sensing and transmission system.

To achieve the above primary object, the ultrasonic assisted machining sensing and transmission system of the present invention is combined with a motor, an amplitude amplifying member and a tool, wherein the ultrasonic assisted machining sensing and transmission system comprises: at least one sensing member At least one vibrating member; a connecting member for connecting the at least one sensing member, the at least one vibrating member and the amplitude amplifying member; and a transmitting member coupled to the amplitude amplifying member and the cutter, wherein the transmitting member The device further includes a fixed ring, a plurality of rotating carriers, and a rotating ring, wherein the plurality of rotating carriers are disposed between the rotating ring and the fixing ring; and by the above configuration, the vibration of the at least one vibrating member can pass through the The transmission member is transmitted to the tool and is measured by the at least one sensing member.

According to an embodiment of the invention, the inner diameter of the retaining ring and the inner diameter of the rotating ring are substantially the same.

According to an embodiment of the invention, the plurality of rotating carriers are a plurality of balls.

In order to enable the reviewing committee to better understand the technical contents of the present invention, the preferred embodiments are described below.

Referring to FIG. 1 and FIG. 2 of the present invention together, the ultrasonic assisted machining sensing and transmission system 1 of the present invention includes a mechanism common to general ultrasonic assisted machining such as the vibrating member 20, the amplitude amplifying member 30, the cutter 60, and the motor 70. In addition, the present invention further includes a sensing member 10, a connecting member 40, and a transmission member 50. According to the present embodiment, the vibrating member 20 and the sensing member 10 are all piezoelectric materials, and deformation can be generated by conduction, and applying a pressure thereto to deform can also generate a potential difference. The present invention relies on the complex vibrating member 20 to generate ultrasonic vibration by the inverse piezoelectric effect, thereby performing ultrasonic processing; and the sensing member 10 of the present case senses the vibration of the vibrating member 20 to generate a small amount of current by using a positive piezoelectric effect, and A voltage detecting controller (not shown) is electrically connected to measure whether the vibration output frequency and amplitude of the vibrating member 20 are in line with expectations. Because it is directly mechanically sensed, its feedback signal is less affected by external environmental factors, and signal analysis will result in more accurate results. Among them, the way in which the voltage detection controller is used to receive power feedback is a conventional technique, which is not the focus of this case, and therefore will not be described again. It should be noted that the vibrating member 20 and the sensing member 10 are not necessarily located in the system, and can be adjusted according to installation requirements. For example, when the system is mounted on the processing machine, the vibrating member 20 can be located under the sensing member 10, or The sensing member 10 is located below the vibrating member 20.

According to the embodiment, the connecting member 40 is a male threaded sleeve, and the member having the matching female thread includes the amplitude amplifying member 30, the locking ring 81, the insulating ring 82, the nut 83, and the vibrating member 20 and the sense. The measuring member 10 is a hollow piezoelectric ring (not threaded), and the connecting member 40 can be connected in series as shown in FIG. 1 and fix the amplitude amplifying member 30, the vibrating member 20, the locking ring 81, the vibrating member 20, the insulating ring 82, The sensing member 10 and the nut 83 are provided. The amplitude amplifying member 30 is used in the ultrasonic assisted processing to enhance the amplitude and achieve the vibration effect required for processing; the locking ring 81 has a large disc shape and is additionally connected to the outer casing of the system (not shown) to prevent processing. The processing fluid is splashed; the insulating ring 82 is used to isolate the vibrating member 20 having the power receiving transmission and the sensing member 10; the nut 83 is engaged with the connecting member 40 to lock the sensing system. There are many connection methods in the above series, such as the unevenness of the components, but this is not the focus of this case, so it will not be described again.

As shown in FIG. 2, the transmission member 50 includes a fixing ring 51, a rotating carrier 52, and a rotating ring 53. The fixing ring 51 is connected to the amplitude amplifying member 30 and can be screwed (not shown). , or other suitable connection method. The rotating carrier 52 is interposed between the rotating ring 53 and the fixing ring 51. The rotating ring 53 is used to connect the cutter 60, and can be screwed (not shown), or other suitable connection manner. The retaining ring 51 and the rotating ring 53 are substantially annular pieces of the same inner and outer diameter and size for receiving the rotating carrier 52.

Wherein, the cutter 60 is connected to the rotating ring 53 of the transmission member 50, and the end thereof is also locked with a motor 70 of a processing machine, thereby being rotated by the motor 70 for processing, and the transmission member 50 can longitudinally generate the vibrating member 20. The displacement is effectively transmitted to the ultrasonic assisted processing rotary tool, and the sensing system does not rotate, so there is no need to consider the winding problem that the transmission wire may have during the rotation process, or the piezoelectric piece needs to be brushed with the brush. The problem of wear caused by contact. The fastening method of the motor and the cutter is a conventional technique, and will not be described herein.

According to the embodiment, the rotating carrier 52 is a plurality of balls for riding the fixing ring 51 and the rotating ring 53. When the rotating ring 53 is rotated along with the cutter 60, the balls are also driven to roll at a high speed, but the rotating carrier 52 is rotated. The structure is not limited to this, and it can also be a needle roller. It should be noted that although the transmission member 50 is actually a common ball bearing, the idea of using a ball bearing to transmit ultrasonic vibration is not a structure used in a general ultrasonic auxiliary processing machine.

The above is merely an embodiment and is not limited to the embodiment. For example, those who do not depart from the basic structure of the present invention should be bound by the scope of the patent, and the scope of the patent application shall prevail.
