[0002] Angle heads are important accessories for CNC machine tools, used to expand the machining range of the machine tool and realize machining tasks at multiple angles and directions. The quick-locking structure of the angle head is one of its core functions, which directly affects machining efficiency, accuracy and ease of operation. Angle heads enable machine tools to perform milling, drilling and other operations at different angles, and are suitable for machining complex parts. By quickly changing angle heads, machine tools can adapt to a variety of machining tasks and reduce equipment investment.

[0003] In the prior art, Chinese Utility Model Application No. CN202223019913.7 discloses a high-precision angle head for CNC machine tools, including an angle head body. A first connecting block is connected to the upper left side of the angle head body, and a second connecting block is connected to the upper right side of the angle head body. A first electric push rod is connected to the upper end of the first connecting block, and a second electric push rod is connected to the upper end of the second connecting block. The upper ends of both the first and second electric push rods are connected to a mounting block. This utility model, by setting up a mounting block, a first electric push rod, a second electric push rod, a first connecting block, a second connecting block, a left support plate, a right support plate, and a limiting ring, utilizes the mutual cooperation between these components to adjust the working height between the angle head body and the machine tool spindle, expanding the application range, enhancing flexibility, and making the angle head body more stable during operation, thus improving machining accuracy.

[0004] In the existing technology, machine tool angle heads are usually locked using a retaining ring or a single T-block. However, the retaining ring locking method is inconvenient to disassemble and assemble, reducing the efficiency of changing angle heads. At the same time, the contact area between the retaining ring and the angle head is small, and the stability of locking the angle head needs to be further improved. Therefore, we need to propose a quick locking structure for machine tool angle heads. Utility Model Content

[0005] The purpose of this utility model is to provide a quick locking structure for a machine tool angle head, which uses symmetrically arranged T-shaped blocks to lock the angle head body, improving the convenience of disassembling and assembling the angle head body while improving the stability of the angle head body during installation, thereby improving the stability of the angle head body during use and improving the quality of parts production, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-locking structure for a machine tool angle head, comprising a rotating ring, an annular groove on the lower surface of the rotating ring, two sets of T-shaped blocks installed in the annular groove, the lower ends of the two sets of T-shaped blocks being threadedly connected to multiple sets of screws, the lower ends of the multiple sets of screws being through-hole angle head bodies, the lower ends of the multiple sets of screws being sequentially provided with washers and nuts from top to bottom, the angle head body being disposed between the washers and the T-shaped blocks, and the multiple sets of screws being arranged at equal angles.

[0007] Preferably, an angle head handle is provided above the rotating ring and located in the annular groove, with the lower end of the angle head handle passing through the annular groove and installed on the upper end of the angle head body.

[0008] Preferably, one end of the upper surface of the rotating ring is provided with a mounting hole, and a positioning pin for positioning the rotating ring is provided in the mounting hole. Two sets of grooves are symmetrically provided on the upper end of the positioning pin.

[0009] Preferably, the annular groove has a convex cross-section, the T-shaped long block has an L-shaped cross-section, and the lower end of the T-shaped long block has a screw hole for installing multiple sets of screws, and the screw hole is filled with thread-locking adhesive.

[0010] Preferably, the outer side of the angle head body is provided with an annular scale, and the upper end of the angle head body is provided with a through hole for multiple sets of screws to pass through.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention primarily utilizes the cooperation between a rotating ring, annular groove, T-shaped blocks, screws, and nuts. The screws facilitate the limiting of the angle head body, allowing multiple sets of nuts to fix the angle head body onto multiple sets of screws, thus improving the stability of the angle head body installation. By loosening the nuts and rotating the angle head body 360 degrees, the angle of the angle head body can be adjusted according to the actual processing angle direction, making disassembly and assembly convenient. Furthermore, the use of two sets of T-shaped blocks increases the contact area with the angle head body, improving the stability of the angle head body during the part processing.

Then, screw the multiple sets of screws 4 into the multiple sets of screw holes and abut against the bottom of the annular groove 9, thereby improving the positioning effect of the T-shaped long blocks 3. The angle head body 5 is connected to the multiple sets of screws 4 through the through hole, and a washer 6 is first fitted on the multiple sets of screws 4. The washer 6 is then locked with a nut 7, thereby improving the stability of the angle head body 5 installation. The angle head tool holder 1 passes through the annular groove 9 and is connected to the angle head body 5. The angle head tool holder 1 is easily installed on the machine tool spindle using a positioning pin 8. When it is necessary to replace or adjust the angle of the angle head body 5, loosen the multiple sets of nuts 7, and the angle head body 5 can be rotated 360 degrees. The angle of the angle head body 5 can be adjusted according to the actual machining angle direction.
