However, the production threshold of existing universal fixtures is low, and the quality of universal fixtures on the market varies greatly. When processing workpieces, the clamp volume is too large and the clamping force is difficult to control, resulting in unstable clamping and cumbersome operation, which affects the processing accuracy of the noise reduction ball valve core workpiece. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a numerically controlled five-axis machining tool for a marine noise reduction valve core.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

[0007] Optionally, a Φ6mm pin hole and an M5 threaded hole are provided on the vertical surface of the right-angle bent plate, and a Φ6mm pin hole and an M5 screw countersunk hole for connecting the right-angle bent plate are provided on the flange. By using M5 screws, the M5 screw countersunk holes of the flange can be inserted into the M5 threaded holes of the right-angle bent plate for fixation.

[0008] Optionally, an M21 threaded hole for connecting a quick-change support head is provided inside the flange, and the M21 threaded hole facilitates rapid replacement of a quick-change support head of a suitable size.

[0009] Optionally, an M31 reverse threaded hole matching with the locking sleeve is provided around the middle of the quick-change support head, and the thread direction of the M31 reverse threaded hole is opposite to that of the M21 threaded hole, thereby reducing the occurrence of erroneous operation.

[0010] Optionally, a plurality of M10 threaded holes are provided on the side of the locking sleeve, and a locking screw for applying force to rotate the locking sleeve is screwed into one of the M10 threaded holes, so that the locking sleeve can be easily rotated by applying force through the locking screw.

DETAILED DESCRIPTION

[0025] The utility model will now be described in further detail with reference to the accompanying drawings.

[0026] See also Figure 1-5 As shown, in this embodiment, a CNC five-axis machining tool for a marine noise reduction valve core is provided, which is installed on a rotary table 3 in a CNC five-axis machine tool 1 and fixed by a pressure plate 4 on the top of the rotary table 3. The CNC five-axis machine tool 1 is connected to a controller 2 for controlling the adjustment of the rotary table 3, including: a right-angle bent plate 5, which is fixed by pressing the pressure plate 4, and a flange 7 and a pin 6 for positioning the flange 7 are arranged on the right-angle bent plate 5. The end of the flange 7 is threadedly matched with a quick-change support head 12, and a limit block 9 is sleeved on the middle peripheral side of the quick-change support head 12, and a locking sleeve 10 is matched with the reverse thread. The limit block 9 is located between the head of the quick-change support head 12 and the locking sleeve 10, and an M41 thread is arranged on the peripheral side of the head of the quick-change support head 12, and a cross groove is opened on the head of the quick-change support head 12. The expansion force is increased by the cross groove to generate a larger contact area between the outer wall of the quick-change support head 12 and the inner hole surface of the workpiece of the noise reduction ball valve core 8.

[0027] The application of one aspect of this embodiment is as follows: the noise reduction ball valve core 8 workpiece to be processed is installed on the M41 thread of the quick-change support head 12, the pin 6 is inserted into the pin hole of the right-angle bent plate 5, and then the flange 7 is aligned with the pin 6 and inserted, and then the right-angle bent plate 5 and the flange 7 are fixedly connected with the M5 screw, the tail of the quick-change support head 12 is first inserted into the limit block 9 and then into the locking sleeve 10, and then the tail of the quick-change support head 12 is connected and fixed with the M21 thread of the flange 7. In order to prevent the noise reduction ball valve core 8 workpiece from loosening, the locking sleeve 10 and the limit block 9 are cooperated to apply a tightening force to the head of the quick-change support head 12 where the cross groove is located, so that the head of the quick-change support head 12 is deformed, so that the noise reduction ball valve core 8 workpiece has a larger and more balanced clamping force. When the noise reduction ball valve core 8 workpiece needs to be rotated 180 degrees in a symmetrical direction for processing, the M5 screw is removed, the flange 7 is rotated 180 degrees, and then aligned with the pin 6 and inserted, and then fixed with the M5 screw again.

[0028] The vertical surface of the right-angle bent plate 5 of this embodiment is provided with a Φ6mm pin hole and an M5 threaded hole, and the flange 7 is provided with a Φ6mm pin hole and an M5 screw countersunk hole for connecting the right-angle bent plate 5. By using an M5 screw, the M5 screw countersunk hole of the flange 7 can be inserted into the M5 threaded hole of the right-angle bent plate 5 for fixation. The Φ6mm pin hole of the flange 7 is aligned with the Φ6mm pin hole of the right-angle bent plate 5 and the pin 6 is inserted, so that the noise reduction ball valve core 8 workpiece can improve the accuracy of repeated positioning, thereby facilitating the positioning accuracy after rotating 180°, and also allowing the operator to reduce the time for aligning the noise reduction ball valve core 8 workpiece.

[0029] An M21 threaded hole for connecting a quick-change support head 12 is provided inside the flange 7 of this embodiment. The connecting and fixing shaft of the quick-change support head 12 can be screwed into the M21 threaded hole for fixation. Through the M21 threaded hole, when it is necessary to process noise reduction ball valve core 8 workpieces of different sizes, the quick-change support head 12 of suitable size can be quickly replaced.

[0030] An M31 reverse threaded hole matching the locking sleeve 10 is arranged around the middle of the quick-change support head 12 of the present embodiment. The M31 reverse threaded hole has a thread direction opposite to that of the M21 threaded hole. This reduces the risk of the quick-change support head 12 threadedly connected to the flange 7 being driven when the locking sleeve 10 is locked or loosened, thereby causing the processed noise reduction ball valve core 8 to be scrapped, thereby improving the processing efficiency of the CNC five-axis machine tool 1.

[0031] The locking sleeve 10 of this embodiment is provided with a plurality of M10 threaded holes on its side, and a locking screw 11 is screwed into one of the M10 threaded holes for convenient force rotation of the locking sleeve 10 . The locking screw 11 facilitates the locking sleeve 10 to support or release the limit block 9 .

[0032] The limit block 9 of this embodiment is provided with a 45° bevel on the circumferential side of one end away from the locking sleeve 10, and the head of the quick-change support head 12 is provided with a 45° bevel matched with the limit block 9. The bevel of the limit block 9 fits with the bevel of the quick-change support head 12 to tighten its head, so that the head of the quick-change support head 12 is deformed to open the M41 thread, thereby increasing its contact surface and making the clamping force greater, thereby reducing the probability of loosening and rotation of the noise reduction ball valve core 8 workpiece after clamping.

[0033] The present invention is not limited to the above-mentioned implementation modes. Anyone should be aware of the structural changes made under the inspiration of the present invention. Any technical solution that is the same or similar to the present invention falls within the protection scope of the present invention. The technology, shape, and structure that are not described in detail in the present invention are all known technologies.
