[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] This utility model provides, for example Figure 1-5 The high-speed electric spindle with an angled head shown includes an electric spindle body 1. The output end of the electric spindle body 1 is movably connected to a rotating rod 3 via a universal coupling 2. A fixed ring 4 is fixedly connected to the periphery of the electric spindle body 1. A support ring 15 is fixedly installed on one side of the fixed ring 4. The support ring 15 is located on the periphery of the universal coupling 2. A rotating ring 5 is rotatably installed on the outer side of the support ring 15. Two arc-shaped frames 6 are fixedly connected to one side of the rotating ring 5. A first sliding sleeve 11 and a second sliding sleeve 12 are slidably connected to the outer sides of the two arc-shaped frames 6, respectively. A bushing 13 is fixedly installed between the first sliding sleeve 11 and the second sliding sleeve 12. The rotating rod 3 is located inside the bushing 13 and is rotatably connected to the bushing 13. A scale line 10 is engraved on the front side of the arc-shaped frame 6 inside the second sliding sleeve 12. A pointer 17 corresponding to the scale line 10 is fixedly installed on the inner side of the second sliding sleeve 12.

[0023] The outer periphery of the retaining ring 4 is threaded with multiple first bolts 7, and the retaining ring 4 is fixed to the electric spindle body 1 by the multiple first bolts 7;

[0024] Multiple support frames 8 are fixedly installed on the inner side of the fixed ring 4. One end of each support frame 8 extends to the inner side of the rotating ring 5 and is fixedly connected to the support ring 15.

[0025] The outer periphery of the rotating ring 5 is threaded with multiple second bolts 9, and the rotating ring 5 and the support ring 15 are fixed together by the multiple second bolts 9;

[0026] A guide groove 14 is provided on the inner side of the fixed ring 4, and the guide groove 14 corresponds to the electric spindle body 1;

[0027] The inner side of the second sliding sleeve 12 is provided with a fixing groove 16, and the pointer 17 is fixedly connected to the inner side of the fixing groove 16.

[0028] The rear side of the first sliding sleeve 11 is threaded with a third bolt 18, and the first sliding sleeve 11 is fixed to an arc-shaped frame 6 by the third bolt 18.

[0029] The working principle of the high-speed electric spindle with angled head based on the embodiment is as follows: by fitting the fixing ring 4 on the outside of the universal coupling 2, the rotating rod 3 passes through the bushing 13, and the guide groove 14 guides the electric spindle body 1, the fixing ring 4 can be fitted around the outside of the electric spindle body 1. By rotating the first bolt 7, the first bolt 7 is used to press the outside of the electric spindle body 1, which can fix the fixing ring 4 and the electric spindle body 1. The bushing 13 can support the rotating rod 3 to rotate, which can facilitate the installation and disassembly of the fixing ring 4 and the electric spindle body 1. The support frame 8 can support and fix the support ring 15, so that the center position of the support ring 15 coincides with the axis of the universal coupling 2.

[0030] By driving the first sliding sleeve 11 and the second sliding sleeve 12 to slide along the outer side of the two arc-shaped frames 6, the bushing 13 can be driven to rotate up and down along the axis of the universal coupling 2, and the rotating rod 3 can be driven to rotate up and down simultaneously, which makes it easy to adjust the angle of the rotating rod 3. The fixed groove 16 makes it easy to observe the value of the pointer 17 pointing to the scale line 10. The rotation angle of the bushing 13 can be quickly adjusted and controlled according to the needs, and the rotation angle of the rotating rod 3 can be adjusted and controlled simultaneously. By rotating the third bolt 18, the third bolt 18 is used to press an arc-shaped frame 6, which can fix the first sliding sleeve 11 and the arc-shaped frame 6, and simultaneously fix the bushing 13.

[0031] By driving the rotating ring 5 to rotate along the support ring 15, the arc frame 6 can be driven to rotate synchronously, causing the arc frame 6 to drive the bushing 13 to rotate. This allows the rotating rod 3 to be flipped in any direction and at any angle, and the flipping direction and angle of the rotating rod 3 can be easily adjusted and controlled. By rotating the second bolt 9, the support ring 15 can be pressed by the second bolt 9, thus fixing the rotating ring 5 and the support ring 15 together.

[0032] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
