The outer cover 10 has a cover top wall 11 and a cover extending from the periphery of the cover top wall 11 to the outer ring. The peripheral wall 12 has an abutting slope 121 on the inner side of the end edge of the outer peripheral wall 12.

Referring to FIGS. 1 to 5 , the springs 20 abut against the bottom wall of the chamber 911 and the outer cover 11 of the outer cover 10 to be applied by the springs 20 to the outer cover 10 . The elastic preload that is displaced toward the push position.

Referring to FIGS. 1 to 5, the inner cover body 30 has an inner cover top wall 31 and an inner cover extending integrally downward from the periphery of the inner cover top wall 31. The peripheral wall 32, the inner cover top wall 31 is located in the outer peripheral wall 12 of the outer cover body 10, and the inner cover peripheral wall 32 is fixedly locked with the main shaft 91. The inner cover peripheral wall 32 is provided with a plurality of radial equal intervals. An annularly arranged displacement hole 321 having an inner conical surface 322 is formed on the inner circumference of the inner peripheral wall 32.

Referring to FIG. 1 to FIG. 5 , the clamping blocks 40 are respectively disposed in the displacement holes 321 of the inner cover body 30 , and can be externally applied to the displacement holes 321 to perform a clamping position to a position. The reciprocating displacement between the loosening positions, the inner end of the clamping block 40 has a clamping curved surface 41 facing the inner surface of the inner peripheral wall 30 of the inner cover, and the outer end of the clamping block 40 and the top surface have a pushed inclined surface 42 A curved wedge surface 43 is formed between the arcuate surface 41 and the top surface.

Referring to FIGS. 1 to 5 , the positioning post 50 has a head portion 51 , a body portion 52 , and a neck portion 53 connected between the head portion 51 and the body portion 52 , and the neck portion 53 is outside the neck portion 53 . The diameter of the head portion 51 and the outer diameter of the body portion 52 is smaller than the outer diameter of the body portion 51. The neck portion 53 and the head portion 51 have a positioning column wedge surface 54. The body portion 52 is locked and fixed to the additional shaft 92. The outer peripheral portion of the body 52 has an outer conical surface 521.

Therefore, the above description is a description of each component of the additional shaft positioning and clamping mechanism 100 of the gantry processing machine provided by a preferred embodiment of the present invention, and the assembly manner thereof, and then the following features are described as follows:

When the additional shaft 92 is to be combined with the main shaft 91, hydraulic oil is first injected between the outer casing 10 and the inner casing 30 (as shown in Fig. 3), and the outer casing 10 is subjected to the hydraulic oil. The pressure acts to shift to the top position, so that The spring 20 is compressed by the outer cover 10 against the spring force of the spring 20. Then, the positioning post 50 is inserted into the inner peripheral wall 32 of the inner cover body 30 (as shown in FIG. 4 ), so that the positioning post 50 can pass through the outer conical surface 521 and the inner cover 30 . The conical surface 322 performs a guiding displacement to correct the positioning. When the neck portion 53 of the positioning post 50 is located at the corresponding position of the displacement hole 321 , the hydraulic oil can be discharged (as shown in FIG. 5 ), so that the outer cover 10 is again pushed by the spring 20 . When the outer cover body 10 is moved to the push-down position, the abutting inclined surface 121 of the outer cover body 10 is pushed against the pushed inclined surface 32 of the clamping block 40, so that the clamping block 40 is moved. Moving from the loose position to the clamping position, the clamping surface 41 of the clamping block 40 abuts against the neck 53 of the positioning post 50, and is abutted by the clamping wedge surface 43 of the clamping block 40. The locating column wedge surface 54 of the positioning post 50 (as shown in FIG. 5), and the outer cover body 10 covers the inner side surface of the peripheral wall 12 and blocks against the outer end of the clamping block 40, so that The clamping block 40 is fixed in position, thereby achieving the purpose of positioning and clamping the additional shaft 92 and the spindle 91.

Therefore, since the creation not only has the effect of clamping, but also can be guided and positioned by the conical surface 521 of the positioning post 50 and the conical surface 322 of the inner cover 30, the relevant position after the bonding is further improved. To be accurate. Moreover, when positioning and clamping by the present creation, it is no longer necessary to use the conventional positioning tooth structure, which not only greatly reduces the required parts, but also greatly reduces the overall volume.

In addition, since the clamping wedge surface 43 of the clamping block 40 and the positioning column inclined wedge surface 54 of the positioning post 50 abut each other, and at this time, the clamping block 40 is subjected to the outer The cover body 10 is prevented from moving, and the outer cover body 10 is pushed by the spring 20, thereby forming a self-locking state to prevent the additional shaft 92 from being disengaged from the main shaft 91 by itself.

Moreover, since the clamping block 40 and the positioning post 50 are clamped by the clamping wedge wedge surface 43 and the positioning post oblique wedge surface 54 abutting each other, the use of the oblique wedge surface can produce the most stable clamping effect. . Moreover, the stroke required for this creation is shorter, and the volume can be effectively reduced.

When the additional shaft 92 is to be separated from the main shaft 91, hydraulic oil is again injected between the outer cover 10 and the inner cover 30 (as shown in Fig. 6), at which time the outer cover 10 is subjected to the hydraulic pressure. The pressure of the oil is displaced to the upper position, so that the spring 10 is compressed by the outer casing 10 against the elastic force of the spring 20. At this time, the clamp 40 is no longer blocked by the outer cover 10, and can be stressed. Moving from the clamping position to the release position, the positioning post 50 is disengaged from the clamping of the clamping block 40, and the additional shaft 92 can be separated from the main shaft 91.

Secondly, although the outer shape of the clip is generally cylindrical in the above embodiment, the outer shape of the clip may be substantially beaded, which can achieve the same effect.

In addition, as shown in FIG. 5, the outer block and the bottom surface of the clamping block 40 further have an abutting slope 44; the outer cover body 10 has an inner side surface of the peripheral wall 12 and has a blocking slope 122 when the outer cover 10 is located. When the position is pushed down, the anti-slanting surface 122 is pushed against the abutting surface 44 to wrap the clamping block 40 at the clamping position.

Furthermore, in the above embodiment, the clamping wedge surface 43 and the positioning column inclined wedge surface 54 are circular arc inclined surfaces; the pressing inclined surface 121 and the pushed inclined surface 42 are arc inclined surfaces; the abutting inclined surface 44 and The anti-slope surface 122 is a circular arc slope.

In the above embodiment, the bottom end of the inner cover body 30 has an inner cover positioning plane 33; the bottom end of the body portion 52 of the positioning post 50 has a chassis 55 extending radially in a ring shape, and the top mask of the chassis 55 has a mask Positioning column positioning plane 551; when the positioning post 50 protrudes into the inner cover body 30, the positioning post positioning plane 551 is attached to the inner cover body positioning plane 33 of the inner cover body 30 for The secondary positioning of the inner conical surface 322 and the outer conical surface 521 is positioned outside.

The above description is only for the preferred embodiment provided by the present invention, and is not intended to limit the scope of implementation of the present invention. All of the relevant artisans in the art are equally varied according to the present creation, and should belong to the present invention. The scope of coverage.
