Description

Technical Field

[0001] This application relates to the field of tool changing technology, and in particular to a quick-change tool structure for a vertical milling machine. Background Technology

[0002] In the field of machining, vertical milling machines are commonly used metal cutting equipment, and rapid tool changing is crucial for improving machining efficiency and production flexibility. Traditional vertical milling machine tool mounting structures mostly use bolt fastening or wedge clamping methods. These methods have obvious drawbacks: bolt fastening requires repeated tightening with tools such as wrenches, making the operation cumbersome and the time spent on each tool change significantly affecting the machine's machining efficiency; wedge clamping structures require precise adjustment of the wedge angle and force, which is not only complex to operate but also prone to loosening after prolonged use, causing tool displacement during cutting, affecting machining accuracy, and even leading to safety accidents.

[0003] In addition, existing tool changing structures generally lack effective positioning and anti-misoperation designs. Operators may neglect to install the tool properly during tool changing or start the machine tool before it is fully locked, which poses a significant safety hazard.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

A tool mounting seat is installed at one end of the support shaft. Rotary shafts are fixed on both outer walls of the tool mounting seat. An adjusting block is rotatably installed on the outer side of the rotating shaft. An adjusting latch is fixed on the inner wall of one end of the adjusting block. One end of the adjusting latch is integrally fixed with a buckle.

[0008] Preferably, the tool mounting base has a replacement cavity inside, and positioning openings are provided on both sides of the tool mounting base.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] This application allows for quick and easy tool changing by pressing a linkage to release the locking latch and simultaneously retract the stop lever, eliminating the need for tools and significantly improving operational efficiency. After tool changing, a spring pushes the stop lever to its limit position, the locking latch resets, and the latch and anti-slip hook secure the tool pin. This double-locking structure effectively resists machining vibrations, ensuring tool stability and machining accuracy.

[0018] The following is in conjunction with the appendix Figs. 1-3 This application will be described in further detail.

[0019] This application discloses a quick-change tool structure for a vertical milling machine. (Refer to...) Figs. 1-3 The system includes a positioning block 1, a support shaft 2 mounted in the middle of the inner wall of the positioning block 1, a tool mounting seat 3 mounted at one end of the support shaft 2, a replacement cavity 4 inside the tool mounting seat 3, and positioning openings 15 on both sides of the tool mounting seat 3. The design of the positioning openings 15 and the pins allows for the adaptation to various specifications of tools, and the tool type can be switched by changing the pins of different sizes.

[0020] like Fig. 2As shown, rotating shafts 6 are fixed to the outer walls of both sides of the tool mounting base 3. Adjusting blocks 5 are rotatably mounted on the rotating shafts 6. A connecting rod 8 is fixedly connected between the two adjusting blocks 5. An adjusting latch 7 is fixed to the inner wall of one end of the adjusting block 5. A buckle 9 is integrally fixed to one end of the adjusting latch 7. An anti-slip hook block 10 is integrally provided to one end of the buckle 9. A stop block 11 is fixed to the inner wall of the anti-slip hook block 10. The transmission structure composed of rotating shafts 6, adjusting blocks 5, connecting rods 8, and other components converts the pressing action into precise locking and unlocking displacement. The mechanical structure is simple and intuitive, with high transmission efficiency and is not easily damaged. The tight connection of each component reduces the risk of failure caused by the complex structure and lowers maintenance costs and difficulty.

[0021] In this application, a retractable stop bar 13 is provided on one side of the connecting rod 8, and retraction holes 12 adapted to the stop bar 13 are provided on both outer walls of the tool mounting base 3. A spring 14 supporting the stop bar 13 is connected to the inner wall of the retraction hole 12. By pressing the connecting rod 8, the adjusting block 5 and the adjusting latch 7 are driven to move together, so that the latch 9 and the anti-slip hook block 10 quickly disengage from the positioning port 15, and simultaneously push the stop bar 13 to retract into the retraction hole 12, thereby releasing the lock on the tool mounting base 3. The entire operation requires only one pressing action, no additional tools are needed, the tool change time is greatly shortened, and the milling machine processing efficiency is improved.

[0022] The implementation principle of the tool quick-change structure of a vertical milling machine in this application embodiment is as follows:

[0023] When a tool needs to be replaced, the operator presses the connecting rod 8 towards the tool mounting seat 3. The connecting rod 8 drives the adjusting blocks 5 on both sides to rotate around the rotating shaft 6, causing the adjusting latch 7 to swing synchronously towards the tool mounting seat 3. At this time, the latch 9 at the end of the adjusting latch 7 and the anti-slip hook block 10 move away from the positioning port 15 as they swing. When the connecting rod 8 approaches the stop rod 13, it pushes the stop rod 13 to compress the spring 14 and retract it in the contraction hole 12. When the connecting rod 8 moves to the rear, the stop rod 13 loses its limiting force and can pop out to limit the front of the stop rod 13. At this time, it is convenient to replace the tool inside the replacement chamber 4. Corresponding pins are installed on both sides of the tool, so that the pins extend outside the positioning port 15.

[0024] After replacement, the spring force of the reset linkage 8 and spring 14 pushes the stop 13 out of the contraction hole 12, restricting the reverse rotation of the adjusting block 5. At the same time, the adjusting latch 7 resets under the action of elasticity or gravity, and the latch 9 and anti-slip hook block 10 re-reset and engage with the pins that fit on both sides of the tool, ensuring that the tool mounting seat 3 will not loosen or rotate during the milling machine operation, thus ensuring machining accuracy and safety.
