Description

Technical Field

[0001] This utility model belongs to the field of lathe accessories technology, and more specifically, it relates to a milling head structure for a turning-milling composite machine tool. Background Technology

[0002] Traditional lathes and milling machines are mainly rotary cutting machines. For some irregular structures, multiple machines need to work together. Currently, lathes that integrate multiple machines use milling-turning composite machines. These machines achieve multi-axis synchronous motion through a CNC system. They combine the control of the turning spindle and the milling cutter head. With more milling heads, the need to replace the cutter heads becomes more frequent. However, the installation of ordinary three-jaw chuck milling heads cannot meet the needs of rapid replacement of multiple cutter heads. Moreover, when multiple milling cutter heads work together in different positions on a component, the waste chips generated can easily splash into the gaps of other milling cutter heads.

[0003] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a milling head structure for a turning-milling composite machine tool, in order to achieve a more practical value. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a milling head structure for a milling and turning composite machine tool. This solves the problem that the installation of ordinary three-jaw chuck milling heads cannot meet the requirements for rapid replacement of multiple cutting heads, and that during the collaboration of multiple milling cutting heads in different positions on a single component, the generated chips easily splash into the gaps of other milling cutting heads.

[0005] The purpose and effect of this utility model's milling head structure for a milling and turning composite machine tool are achieved through the following specific technical means:

[0006] A milling head structure for a milling and turning machine tool includes an end head body and an outer cover. The end head body has multiple chucks slidably disposed at its front end, with the tops of the chucks inclined. The outer cover is slidably disposed on the end head body and is connected to a telescopic mechanism via multiple connecting rods. A guide sleeve is installed on the inner wall of the outer cover, and the inclined surface of the inner wall of the guide sleeve abuts against the top surfaces of the multiple chucks. A retaining ring is installed at the front end of the outer cover.

[0007] Furthermore, the front side of the end body is provided with multiple sliding grooves, which are distributed in a circular pattern. A slider is integrally provided on the claw, and the slider is slidably engaged in the sliding groove. A spring is provided between the bottom of the sliding groove and the slider.

[0008] Furthermore, the front opening of the outer cover is recessed to form a stepped inner step, the retaining ring is engaged in the inner step, and multiple positioning elements are provided between the inner step and the retaining ring.

[0009] Furthermore, the positioning element includes a plurality of positioning tubes disposed on the inner step, the positioning tubes passing through the retaining ring, and the ends of the positioning tubes being fastened with a locking buckle that restricts the retaining ring.

[0010] Furthermore, the guide sleeve fits against the inner wall of the outer cover, and the guide sleeve is connected to the outer cover by multiple bolts.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The design of the outer cover being fastened to the front end of the end body avoids the direct exposure of multiple jaws, reducing the amount of waste entering the gaps between the jaws. At the same time, moving the outer cover causes multiple jaws to close and clamp the cutter head, which is suitable for quick replacement of multiple milling heads. Furthermore, the retaining ring extends into the cutter head, and during the milling process, waste can be blocked by the retaining ring. Attached Figure Description

[0021] Example:

[0022] As attached Figure 1 To be continued Figure 3 As shown:

[0023] This utility model provides a milling head structure for a turning and milling composite machine tool, including an end head body 1 and an outer cover 2. Multiple jaws 4 are slidably arranged at the front end of the end head body 1. The top of the jaws 4 is inclined, and the multiple jaws 4 surround to form a circle. The center of the multiple jaws 4 forms a space for clamping the cutting head.

[0024] The outer cover 2 is slidably mounted on the end body 1, and the outer cover 2 is connected to the telescopic mechanism through multiple connecting rods 3. The telescopic mechanism is a telescopic mechanism inside the machine tool, such as a cylinder, which is existing technology and will not be described. A guide inner sleeve 8 is installed on the inner wall of the outer cover 2. The inclined surface of the inner wall of the guide inner sleeve 8 abuts against the top surface of multiple jaws 4. When the outer cover 2 moves towards the end body 1, the guide inner sleeve 8 will push the multiple jaws 4, causing the multiple jaws 4 to move closer to each other, thereby clamping and fixing the tool head.

[0025] The inner guide sleeve 8 fits against the inner wall of the outer cover 2, and the inner guide sleeve 8 is connected to the outer cover 2 by multiple bolts 7. The inner guide sleeve 8 is replaceable, lubricated, and reduces wear on the claws 4.

[0026] The front side of the end body 1 has multiple sliding grooves 9, which are distributed in a circle. A slider 401 is integrally provided on the claw 4. The slider 401 is slidably locked in the sliding groove 9. A spring 10 is provided between the bottom of the sliding groove 9 and the slider 401. When the outer cover 2 moves inward, it guides the inner sleeve 8 to drive the multiple claws 4 to close and clamp the cutter head. When the outer cover 2 moves outward away from the end body 1, the spring 10 can drive the multiple claws 4 to spread out, thereby releasing the clamping of the cutter head, making the replacement of the cutter head faster and more convenient.

[0027] During the installation of the cutter head, a retaining ring 5 is installed at the front end of the outer cover 2. In this embodiment, the retaining ring 5 is made of rubber and has a deformable function. The front opening of the outer cover 2 is recessed to form a stepped inner step 201. The retaining ring 5 is locked in the inner step 201. Multiple positioning elements 6 are provided between the inner step 201 and the retaining ring 5, including a positioning tube 601. The positioning tube 601 passes through the retaining ring 5. The end of the positioning tube 601 is fastened with a lock 602 that restricts the retaining ring 5. The retaining ring 5 can be positioned by the positioning tube 601. At the same time, the lock 602 is fastened on the positioning tube 601 to block the retaining ring 5, so that the retaining ring 5 is tightly attached to the inner step 201.

[0028] The outer diameter of the latch 602 is larger than that of the positioning tube 601, which can cover the retaining ring 5 and limit its movement. The elastic torque extending from the inside of the latch 602 can be inserted into the positioning tube 601 to lock it.

[0029] During the milling process, the chips can be blocked by the retaining ring 5. The inner diameter of the retaining ring 5 can be set to be smaller than the diameter of the cutter head. After the cutter head passes through the retaining ring 5, the retaining ring 5 deforms and becomes concave. During the process of the outer cover 2 moving and clamping the cutter head, the concave center of the retaining ring 5 slowly recovers and may even bulge out, tightly wrapping around the periphery of the cutter head and blocking the chips.

[0030] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
