Description

Technical Field

[0001] The invention relates to the technical field of ultrasonic cutting, and in particular to an ultrasonic tool holder mechanism for a six-axis integral 3D ultrasonic machine tool. Background Art

[0002] The ultrasonic toolholder structure is a device that drives the cutting tool for processing through the principle of ultrasonic vibration. It is usually composed of a transducer, a toolholder body and a cutting tool. The transducer converts electrical energy into high-frequency ultrasonic vibrations and transmits it to the cutting tool through the toolholder. The ultrasonic toolholder can significantly improve cutting efficiency, reduce tool wear, and improve the quality of the processed surface, especially when processing hard and brittle materials or precision processing. In addition, the ultrasonic toolholder can also reduce the thermal impact during processing, reduce cutting force, and improve the processing accuracy of the workpiece. This technology is widely used in precision machining, medical device manufacturing and other fields.

[0003] When the ultrasonic toolholder is installed on the ultrasonic spindle, in order to power the transducer of the ultrasonic toolholder, some ultrasonic machine tools are powered by slip rings. The slip ring power supply method uses physical contact to transfer electrical energy through the contact between the brush and the slip ring, which can achieve high-power stable transmission. It is particularly suitable for applications that require higher energy input, such as the transducer and amplitude transformer system in the ultrasonic toolholder. In order to reduce the physical wear between the slip ring and the brush, lubricating oil is usually provided inside the slip ring. However, the speed of lubricating oil replacement in the prior art is extremely slow. The removal of the brush increases the operation steps and maintenance time, significantly reduces the maintenance efficiency, and prolongs the equipment downtime. Secondly, the contact accuracy between the slip ring and the brush may decrease during the removal and displacement of the brush, thereby affecting the stability of the power supply. In addition, the removal of the brush is likely to damage or affect the sealing of the slip ring sealing structure, thereby increasing the risk of lubricating oil leakage and contamination, and further reducing the lubrication effect and protection ability inside the slip ring. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the speed of lubricating oil replacement in the prior art is extremely slow, and the removal of the brush increases the operation steps and maintenance time, significantly reduces the maintenance efficiency, and prolongs the equipment downtime. Secondly, the contact accuracy between the slip ring and the brush may decrease during the removal and displacement of the brush, thereby affecting the stability of the power supply.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. The present invention is provided with a top ring box, a bottom ring box, a top horizontal brush and a bottom horizontal brush at the top of the driving spindle. The top ring box, the bottom ring box, the top horizontal brush and the bottom horizontal brush constitute an annular power supply component of the tool handle body. The inner cavities of the bottom ring box and the top ring box are used to store lubricating liquid. One end of the top horizontal brush and the bottom horizontal brush are in contact with the inner wall of the bottom ring box and the top ring box. A lubricating liquid quick replacement component is provided inside the bottom ring box and the top ring box. The lubricating liquid quick replacement component can quickly squeeze out the lubricating liquid stored in the bottom ring box and the top ring box, and introduce new lubricating oil into the bottom ring box and the top ring box.

[0018] 2. The present invention provides a transverse movement assembly near the lubricating liquid quick replacement assembly, and the transverse movement assembly of a purely mechanical structure is linked with the lubricating liquid quick replacement assembly. When the lubricating liquid quick replacement assembly gradually discharges the old lubricating liquid, it cleverly drives the top transverse brush and the bottom transverse brush to retract into the driving spindle through the transverse movement assembly, making room for the first ring piece and the second ring piece, which are one of the core components of the lubricating liquid quick replacement assembly, to move in the vertical direction, thereby effectively avoiding direct contact and potential wear between the brush and the first ring piece and the second ring piece. The purely mechanical structure design of the transverse movement assembly does not require an additional electronic control system, and has stable operation and a low failure rate. At the same time, it can accurately cooperate with the lubricating liquid replacement process, making room for the first ring piece and the second ring piece to move in the vertical direction, thereby avoiding tedious disassembly work.

[0019] 3. A vertical column is fixedly provided between the first ring plate and the second ring plate of the present invention, and a labor-saving release component is provided on one side of the vertical column. The labor-saving release component allows the user to quickly squeeze out the lubricating liquid stored in the bottom ring box and the top ring box with less force, and introduce new lubricating oil into the bottom ring box and the top ring box, which significantly reduces the force applied by the user, so that the old lubricating liquid in the bottom ring box and the top ring box can be quickly squeezed out, and the new lubricating liquid can be smoothly introduced at the same time, thereby improving the replacement efficiency. This design avoids the problem of traditional operations requiring greater force or complex equipment assistance, and reduces the difficulty of manual operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The specific implementation steps and principles of the present invention are as follows:

[0046] The common pipe 12 commonly set up by the two oil supply pipes 13 is connected to an external lubricating oil storage container, and the common pipe 12 commonly set up by the two oil outlet pipes 14 is connected to an external lubricating oil recovery container. When the handle body 2 is installed to the bottom of the driving spindle 18, the fixing sleeve 17 is lifted up manually, and the head of the rivet 5 of the handle body 2 is inserted into the bottom of the inner cavity of the driving spindle 18, and the fixing sleeve 17 is lowered. Due to the existence of the conical cavity 171, the fixing sleeve 17 will drive multiple holding balls 181 to be stuck into the bottom of the rivet 5 of the handle body 2. At this time, the first metal wire 100 contacts the first connecting ring 191, and the second metal Wire 101 contacts the second connecting column 192, and the transducer 8 is powered by the first metal wire 100, the second metal wire 101, the first folded column 21, the second folded column 23, the top horizontal brush 24, the bottom horizontal brush 26, the bottom ring box 16, the top ring box 15, the first wiring 151, and the second wiring 161. At this time, the bottom horizontal brush 26 contacts the inner wall of the bottom ring box 16, and the top horizontal brush 24 contacts the inner wall of the top ring box 15. At this time, the second ring piece 282 and the first ring piece 281 are at the bottom of the inner cavity of the top ring box 15 and the bottom ring box 16, and the driving column 29 is at the top of the inclined groove 284.

[0047] When the lubricating fluid inside the top ring box 15 and the bottom ring box 16 needs to be replaced, the driving main shaft 18 is rotated to drive the driving column 29 to move to the side of the inclined groove 284 on the side of the vertical column 28, and the labor-saving pry bar 33 is repeatedly inserted between the multiple auxiliary shoulders 30 by manpower, and then the labor-saving pry bar 33 is pried to drive the vertical column 28 to move upward. During this period, the second ring piece 282 and the first ring piece 281 move upward along the bottom of the inner cavity of the top ring box 15 and the bottom ring box 16, and the waste oil is discharged through the oil outlet one-way valve 141, and the driving column 29 moves from the inclined groove 284 to the inside of the vertical groove 283, and the top horizontal brush 24 and the bottom horizontal brush 26 retract into the inner cavity of the driving main shaft 18.

[0048] When new lubricating oil needs to be squeezed into the top ring box 15 and the bottom ring box 16, the above steps drive the vertical column 28 to move downward, the first ring plate 281 and the second ring plate 282 extract lubricating liquid through the oil inlet one-way valve 131, and the driving column 29 moves from the vertical groove 283 to the inclined groove 284, and the top horizontal brush 24 and the bottom horizontal brush 26 extend from the inside of the driving main shaft 18 again.
