Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] See also Figure 1-Figure 6 , the utility model provides a technical solution:

[0027] A CNC dividing tool comprises a CNC dividing head 1, a fixed base 2 is fixedly installed on the front of the CNC dividing head 1, a processing head 3 is fixedly installed on the front of the fixed base 2, a processing cavity 4 is opened on the inner side of the processing head 3, a driving seat 5 and a rotating seat 6 are rotatably connected at the upper and lower ends of the processing cavity 4, the driving seat 5 and the rotating seat 6 are opposite ends thereof are slidably connected with a connecting seat 7, two groups of connecting seats 7 are fixedly connected to the driving seat 5 and the rotating seat 6 through a quick-release assembly 8, two groups of connecting seats 7 are slidably connected with clamping blocks 9 at the opposite ends thereof, and an elbow 10 to be processed is clamped between the two groups of clamping blocks 9.

[0028] First, a mounting column 201 is fixedly connected at the center of the back side of the fixed base 2. The mounting column 201 is fixedly installed on the inner side of the CNC dividing head 1. The interior of the processing head 3 is fixedly connected to the fixed base 2 through multiple sets of mounting bolts 202. When the fixed base 2 is installed, the mounting column 201 is fixed by the CNC dividing head 1, so that the fixed base 2 is installed on the front side of the CNC dividing head 1, and the processing head 3 is fixedly installed on the front side of the fixed base 2 through multiple sets of mounting bolts 202.

[0029] Furthermore, an inspection plate 301 is installed on the front of the processing head 3, and the inspection plate 301 is fixedly connected to the processing head 3 by multiple sets of fixing bolts 302. The processing cavity 4 is located on the outside of the processing head 3 and is symmetrically provided with chip removal ports 303. A driving mechanism is installed inside the processing head 3 and at the top of the driving seat 5. The driving mechanism drives the driving seat 5 to rotate, so that after the two sets of clamps 9 clamp and fix the elbow 10 to be processed, the elbow 10 to be processed can be driven to rotate to change the processing position. When special explanation is required here, the driving mechanism is the prior art and will not be described in detail here. The inspection plate 301 can be disassembled by the fixing bolts 302, so as to facilitate the inspection of the internal driving mechanism. When the elbow 10 to be processed is processed, the CNC machine tool head can extend into the interior of the processing cavity 4, and by rotating the elbow 10 to be processed, the various joints of the elbow 10 to be processed can be processed in all directions, and the waste chips generated by the processing are discharged from the chip removal port 303 to avoid clogging of the inner side of the processing cavity 4.

[0030] Then, the quick-release assembly 8 includes a connecting sleeve 801 inserted into the driving seat 5 and the rotating seat 6, the internal thread of the connecting sleeve 801 is connected with a threaded column 802, the end of the threaded column 802 close to the connecting seat 7 is fixedly connected with a first spring 803, the end of the first spring 803 away from the connecting seat 7 is fixedly connected with a moving block 804, the end of the moving block 804 away from the first spring 803 is fixedly connected with a top column 805, an active cavity 806 is provided inside the connecting sleeve 801 and on the outside of the top column 805, a ball 807 is movably installed on the inside of the active cavity 806, when clamping and fixing the processed elbow, first insert the connecting sleeve 801 into the driving seat 5 and the rotating seat 6, then rotate the threaded column 802 to push the first spring 803, so that the moving block 804 moves accordingly, until the top column 805 pushes the ball 807 out of the inner side of the active cavity 806.

[0031] Furthermore, a rubber sealing ring 808 is provided on the outside of the connecting sleeve 801, and a rotating handle 809 is fixedly connected to one end of the threaded column 802 located on the outside of the connecting sleeve 801. A card slot 810 adapted to the ball 807 is provided inside the connecting seat 7. When the connecting sleeve 801 is inserted into the inside of the driving seat 5 and the rotating seat 6, the sealing performance of the connecting sleeve 801 can be improved by the rubber sealing ring 808. When the threaded column 802 is rotated, the rotating handle 809 is twisted to perform the rotating operation, and when the ball After 807 is pushed out from the inner side of the rear movable cavity 806, the ball 807 is inserted into the slot 810, thereby fixing the connecting sleeve 801, and then quickly fixing the connecting seat 7. When it is necessary to process elbows 10 of different shapes and specifications, it is only necessary to gently rotate the threaded column 802 to make the ball 807 retract into the inner side of the movable cavity 806 to release the fixation of the connecting seat 7, thereby facilitating the replacement of the clamping block 9 according to the different elbows 10 to be processed, further improving the applicability of the tooling.

[0032] Secondly, the two groups of clamping blocks 9 are slidably connected to the connecting seat 7 through the telescopic column 901. One end of the telescopic column 901 located inside the connecting seat 7 is fixedly connected to the second spring 902. The connection between the telescopic column 901 and the second spring 902 is fixedly connected to the limiting block 903. When processing the elbow 10 to be processed, it is only necessary to press the two groups of clamping blocks 9 separately to compress the second spring 902 toward the inner side of the connecting seat 7. Under the connection of the telescopic column 901, the two groups of clamping blocks 9 are separated. Then, the elbow 10 to be processed is placed between the two groups of clamping blocks 9 and the clamping blocks 9 are released. Under the reset of the second spring 902, the elbow 10 to be processed is clamped and fixed by the two groups of clamping blocks 9, thereby greatly improving the clamping speed of the elbow 10 to be processed and further improving the convenience of operation.

[0033] Finally, the bottom of the two groups of clamping blocks 9 are slidably connected to the connecting seat 7 through multiple groups of sliding rods 904. The inner sides of the two groups of clamping blocks 9 are provided with positioning clamping grooves adapted for the elbow 10 to be processed. When the clamping blocks 9 move, the multiple groups of sliding rods 904 cooperate to slide, so that the clamping blocks 9 can move stably to ensure the stability of the clamping. When the elbow 10 to be processed is clamped and fixed between the two groups of clamping blocks 9, the elbow 10 to be processed is located in the positioning clamping groove and fits in, thereby ensuring the stability of the processing process.

[0034] In this embodiment, the implementation scenario is specifically as follows: the mounting column 201 is fixed by the CNC dividing head 1, so that the fixed base 2 is installed on the front side of the CNC dividing head 1, and the processing head 3 is fixedly installed on the front side of the fixed base 2 by multiple sets of mounting bolts 202, and then the two sets of clamping blocks 9 are pressed respectively, so that the second spring 902 is compressed toward the inner side of the connecting seat 7, and the two sets of clamping blocks 9 are separated under the connection of the telescopic column 901, and then the elbow 10 to be processed is placed between the two sets of clamping blocks 9 and then the clamping blocks 9 are released, and the elbow 10 to be processed is clamped and fixed by the two sets of clamping blocks 9 under the reset of the second spring 902, thereby greatly improving the clamping speed of the elbow 10 to be processed, and when the elbow 10 to be processed is clamped and fixed, the rolling ball 807 is clamped into the slot 810, thereby fixing the connecting sleeve 801, and then quickly fixing the connecting seat 7. When processing the elbow 10 to be processed, the CNC machine tool cutter head can extend into the processing cavity 4, and rotate by driving the driving seat 5. The elbow 10 to be processed is rotated under the connection of the rotating seat 6, so that the various joints of the elbow 10 to be processed can be processed in all directions. When it is necessary to process elbows 10 to be processed of different shapes and specifications, it is only necessary to gently rotate the threaded column 802 outward to make the ball 807 retract into the inner side of the active cavity 806 to release the fixation of the connecting seat 7, thereby facilitating the replacement of the clamping block 9 according to the different elbows 10 to be processed, further improving the applicability of the tooling, and the entire operation process is simple and convenient. Compared with the existing CNC dividing head 1 processing elbow method, the utility model can improve the clamping speed of the processed elbow through design, improve the convenience of operation, and at the same time improve the applicability of the tooling.
