[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0020] A fixture for electric spindle machining, such as Figure 1-4 As shown, it includes a base plate 1 and mounting frames 5 arranged at both ends of the base plate 1, and positioning shafts 3 are rotatably inserted at both ends of the two mounting frames 5. The main shaft body 2 is clamped between the multiple positioning shafts 3, and a knob bolt 14 is provided on the mounting frame 5 to abut against the positioning shaft 3. A turntable 11 is fixed to the side wall of one of the positioning shafts 3, and fixing frames 16 are provided on both sides of the top surface of the base plate 1. The mounting frame 5 is slidably inserted in the fixing frame 16, and the side wall of the fixing frame 16 is installed with a hydraulic rod 6 for driving the mounting frame 5.

[0021] Support frames 4 are provided on both sides of the top surface of the base plate 1, and the fixing frame 16 is fastened and inserted in the support frame 4. The bottom end of the support frame 4 is provided with a fastening seat 8, and the top of the fastening seat 8 is provided with a plurality of screws 7 threadedly inserted in the base plate 1. A baffle 12 is installed on one end of the positioning shaft 3, and a rubber anti-slip pad 9 is embedded and fixed on the other end of the positioning shaft 3. A telescopic groove 18 is provided on the side wall of the fixing frame 16, and the mounting frame 5 is slidably inserted in the telescopic groove 18, and a push rod 17 connected to the hydraulic rod 6 is fixed on the side wall of the mounting frame 5. The hydraulic rod 6 drives the mounting frame 5 and the positioning shaft 3 to move synchronously through the push rod 17, and clamps the main shaft body 2 during the movement. Since the positioning shaft 3 is rotatably installed in the mounting frame 5 through the bearing 15, the positioning shaft 3 is rotated by the turntable 11 to drive the main shaft body 2 to rotate synchronously.

[0022] Furthermore, a bearing 15 connected to the positioning shaft 3 is embedded in the mounting frame 5, and a protrusion 13 is provided on the outer wall of the mounting frame 5. A plurality of grooves 10 are provided on the outer wall of the positioning shaft 3. The knob bolt 14 is threadedly inserted into the protrusion 13, and the bottom end of the knob bolt 14 abuts against the groove 10. The knob bolt 14 at the top of the protrusion 13 is tightened to abut against the inner wall of the groove 10, so that the positioning shaft 3 maintains axial positioning. At the same time, the rubber anti-slip pad 9 on the positioning shaft 3 increases the friction between the main shaft body 2, so that the axially fixed positioning shaft 3 clamps the main shaft body 2.

[0023] The working principle of the present utility model is as follows: when in use, the main shaft body 2 is placed between multiple positioning shafts 3, the hydraulic rod 6 is started to make the push rod 17 drive the mounting frame 5 and the positioning shaft 3 to move synchronously, and the main shaft body 2 is clamped and fixed during the movement. Since the positioning shaft 3 is rotatably installed in the mounting frame 5 through the bearing 15, the positioning shaft 3 is rotated by the turntable 11 to drive the main shaft body 2 to rotate synchronously, thereby improving the convenience of adjusting different angles of the main shaft body 2. After adjusting the angle of the main shaft body 2, the knob bolt 14 at the top of the protrusion 13 is tightened to make it abut against the inner wall of the groove 10, so that the positioning shaft 3 maintains axial positioning. At the same time, the rubber anti-slip pad 9 on the positioning shaft 3 increases the friction between the main shaft body 2, so that the axially fixed positioning shaft 3 clamps the main shaft body 2, thereby improving the stability of the main shaft body 2 after fixation.
