[0027] As Figure 3As shown in the figure, a connecting component of a horizontal machining center spindle head. The reinforcement connecting component 3 is used to reinforce and seal the connection. The anti-rotation slot 302 forms an engaging structure with the first anti-rotation block 303 and the second anti-rotation block 304, and the anti-rotation slot 302 is arranged at equal intervals on the inner wall of the first fixing clamp 301. There are two sealing rubber rings 305 symmetrically arranged about the vertical central axis of the first fixing clamp 301, and the material of the sealing rubber ring 305 is set as rubber material. The first fixing clamp 301 and the second fixing clamp 308 form a detachable structure through the second fixing bolts 306 and the fixing nuts 307, and there are two second fixing bolts 306 symmetrically arranged about the vertical central axis of the first fixing clamp 301. On the basis of flange connection, a clamp connection is also provided, which is convenient for further enhancing the stability of the connection between the spindle head and the horizontal machining center. And an anti-rotation slot 302 is arranged on the inner wall of the clamp, and corresponding first anti-rotation block 303 and second anti-rotation block 304 are arranged on the outer wall of the flange, so that they can engage and limit each other, which is convenient for further enhancing the stability of fixation and preventing the clamp from rotating outside the flange. And sealing rubber rings 305 are arranged at the connection positions of the clamp with the spindle head body 1 and the spindle head connection 5, which is convenient for sealing the connection and preventing waste such as metal chips and coolant generated during the machining process from invading the gap of the connection and affecting the stability of the connection.

[0028] As Figure 4 shown in the figure, a connecting component of a horizontal machining center spindle head. The flange connecting component 2 includes a first connecting flange 201. The first connecting flange 201 is internally threadedly connected with a first fixing bolt 202, and an insertion column 203 is fixedly connected to the side of the first connecting flange 201. And the outer part of the insertion column 203 is snap-connected with a second connecting flange 204. The first connecting flange 201 and the second connecting flange 204 form a thread-detachable structure through the first fixing bolt 202, and the first fixing bolts 202 are arranged at equal angles about the central axis of the second connecting flange 204. By continuously screwing in the first fixing bolts 202, the first connecting flange 201 and the second connecting flange 204 can be tightened, so that the two are firmly fixed together, and then the spindle head body 1 and the spindle head connection 5 can be firmly fixed together, which is convenient for ensuring the transmission accuracy and then ensuring the machining accuracy. At the same time, an insertion column 203 is provided, which can facilitate the guiding and limiting of the first connecting flange 201 and the second connecting flange 204, and prevent the flange from shifting during the process of screwing the first fixing bolts 202.

[0029] As Figure 5As shown, a connecting component for the spindle head of a horizontal machining center. The spindle head connecting and positioning component 4 includes an insertion block 401.

[0030] Working principle: When the spindle head needs to be installed at the connection of the horizontal machining center, first align the positioning slot 404 with the positioning block 402 and insert it. At the same time, the insertion block 401 also inserts into the insertion slot 403. At this time, the connection surfaces of the first connection flange 201 and the second connection flange 204 just stick together, and the insertion posts 203 on the side of the first connection flange 201 will align and insert into the holes inside the second connection flange 204. Then use tools to screw the first fixing bolt 202 into the screw hole inside the first connection flange 201, and screw its end into the inside of the second connection flange 204 and tighten it, so as to connect and fix the second connection flange 204 and the first connection flange 201 together. Thus, the spindle head body 1 and the spindle head connection 5 can be connected and fixed together by using the two flanges.

[0031] Then clamp the first fixing clamp 301 above the first connection flange 201 and the second connection flange 204. At the same time, make the first anti-rotation block 303 and the second anti-rotation block 304 snap into the anti-rotation slot 302. Then align and clamp the second fixing clamp 308 below the two flanges, so that the two fixing clamps just form a circle and clamp outside the flanges. Then screw the second fixing bolt 306 into the ends of the first fixing clamp 301 and the second fixing clamp 308 in turn to fix the two of them, and screw on the fixing nut 307 for further tightening and fixing. At the same time, the sealing rubber ring 305 on the inner wall of the clamp will tightly stick to the outer wall of the spindle head body 1 and the spindle head connection 5 to seal the space inside the two clamps.
