[0033] In the embodiment of the application, as shown in Figures 2-4 The positioning mechanism includes a driving gear 9 rotatably connected to the inner cavity bottom of the installation groove 16 through a rotating shaft 8, the other end of the rotating shaft 8 extends to the below of the mounting base 2 and is fixedly connected with the hand turntable 7, a plurality of driven gears 10 are meshingly connected to the outer surface of the driving gear 9, a concentric shaft 11 is fixedly connected to the inside of the driven gear 10, the bottom of the concentric shaft 11 is rotatably connected with the inner cavity bottom of the installation groove 16, an adjusting gear 12 is fixedly connected to the top of the concentric shaft 11, a positioning toothed plate 13 is meshingly connected to one side of the adjusting gear 12, and one end of the positioning toothed plate 13 extends to the inside of the positioning groove 6.

[0034] Through the above technical scheme, the installation base 2 and the electric main shaft body 3 can be quickly fixed by the positioning mechanism, thereby greatly facilitating the installation and disassembly of the electric main shaft body 3 by the operator, and greatly improving the assembly efficiency of the device for the electric main shaft body 3.

[0035] In the embodiment of the application, as shown in Figure 5 The locking mechanism 14 includes a groove formed on the bottom of the mounting base 2, a locking base 141 is fixedly connected to the inner cavity bottom of the groove, a return spring 142 is fixedly connected to the inside of the locking base 141, the other end of the return spring 142 is fixedly connected with a locking rod 143, and the side of the locking rod 143 away from the return spring 142 extends to the outside of the hand turntable 7 through the locking hole 15.

[0036] By adopting the technical scheme, the hand rotating disc 7 can be locked by the locking mechanism 14, so that the hand rotating disc 7 can be prevented from rotating after installation, and the installation stability of the device is greatly improved.

[0037] In the embodiments of the present application, as shown in Figures 4-5 The locking base 141 is located inside the installation base 2 and does not contact the hand rotating disc 7.

[0038] By adopting the technical scheme, since the locking base 141 is located inside the groove at the bottom of the installation base 2 and does not contact the hand rotating disc 7, when the locking rod 143 is retracted into the locking base 141, the hand rotating disc 7 is in an unlocked state, and when the locking rod 143 is extended from the locking hole 15, the hand rotating disc is in a self-locking state.

[0039] In the embodiments of the present application, as shown in Figure 4 The outer surface of the hand rotating disc 7 is fixedly connected with an anti-skid sleeve.

[0042] By adopting the technical scheme, the two locking holes 15 can more conveniently perform self-locking treatment on the hand rotating disc 7.

[0043] In use, the operator can first weld the fixing frame 1 on the machining table, and then insert the clamping block 5 at the bottom of the electric spindle body 3 into the clamping groove 4 of the mounting base 2, and then press the locking rod 143 to retract it into the locking base 141 by compressing the reset spring 142. Since the locking base 141 is located in the groove at the bottom of the mounting base 2 and does not contact the hand wheel 7, the hand wheel 7 is in an unlocked state at this time. Then the operator rotates the hand wheel 7 clockwise, so that the hand wheel 7 can drive the driving gear 9 to rotate through the rotating shaft 8. When the driving gear 9 rotates, it will drive the driven gear 10 to rotate through the meshing mode. When the driven gear 10 rotates, it will drive the adjusting gear 12 to rotate through the concentric shaft 11, so that the adjusting gear 12 can drive the positioning tooth plate 13 to insert into the positioning groove 6 in the clamping block 5 through the meshing mode. In this way, the mounting base 2 and the electric spindle body 3 can be quickly fixed, thereby greatly facilitating the operator to install and disassemble the electric spindle body 3, and greatly improving the assembly efficiency of the electric spindle body 3. When the positioning tooth plate 13 is completely inserted into the positioning groove 6, the hand wheel 7 is rotated by one hundred and eighty degrees. At this time, the other locking hole 15 of the hand wheel 7 is just moved to the position of the locking rod 143. At this time, the locking rod 143 will be quickly ejected from the locking hole 15 under the elasticity of the reset spring 142, so as to quickly self-lock the hand wheel 7, thereby effectively avoiding the hand wheel 7 from rotating after installation, and greatly improving the installation stability of the device.
