Detailed Description
The following describes embodiments of the present invention with reference to the drawings. Numerous details are set forth below in order to provide a thorough understanding of the present invention, but it will be apparent to those skilled in the art that the present invention may be practiced without these details.
As shown in fig. 1 to 3, a horizontal servo drilling spindle head comprises a spindle 1, and a water slinging ring 2, a waterproof end cover 3 and a shaft sleeve 4 which are sequentially sleeved outside the spindle 1 from front to back; the waterproof end cover 3 is fixedly connected with the shaft sleeve 4, and the peripheral edge of the waterproof end cover 3 is provided with a drainage groove 30; the water slinger 2 is fixedly connected with the main shaft 1, a water drainage gap 20 communicated with the water drainage groove 30 is arranged between the water slinger 2 and the waterproof end cover 3, and an inclined water drainage platform 21 is arranged on the periphery edge of the water slinger 2 for the water drainage gap 20. When a workpiece is machined, if external cooling water flows into the drainage gap 20, the drainage groove 30 can stop the flowing cooling water at the peripheral edges of the water throwing ring 2 and the waterproof end cover 3, collect and drain the cooling water onto the drainage inclined table 21 of the water throwing ring 2, and the water throwing ring 2 rotates at a high speed along with the main shaft 1, so that the cooling water on the drainage inclined table 21 can be quickly thrown out of the drainage gap 20. Therefore, the water slinging ring 2 and the waterproof end cover 3 are simple in structure and ingenious in design, cooling water can be effectively prevented from entering the interior of the spindle head, and the service life of the spindle head is prolonged.
As shown in fig. 2 and fig. 3, a tapered boss 31 is fixedly arranged at the front end of the waterproof end cover 3, and a drainage channel 30 with an acute included angle is formed between the tapered boss 31 and the waterproof end cover 3. Drainage ditch 30 that is acute angle structural design can play better drainage effect, prevents effectively that cooling water from getting into 3 insides of water ring 2 and waterproof end cover of getting rid of. In order to make the structure of the spindle head more compact and reasonable, the outer diameter of the conical boss 31 is ensured to be smaller than that of the waterproof end cover 3 during design, so that a space is reserved for arranging the drainage sloping platform 21 at the drainage groove 30 of the water slinging ring 2.
As shown in fig. 2 and 3, the water slinging ring 2 is provided with an anti-backflow groove 22 with an opening facing the drainage groove 30 at the drainage sloping platform 21, the anti-backflow groove 22 can prevent cooling water from flowing back to the water slinging ring 2 and the interior of the waterproof end cover 3, and the cooling water can be collected and drained to the drainage groove 30, so that the cooling water is ensured to be drained in time, and the waterproof effect of the spindle head is further improved. Preferably, the included angle between the two side walls of the backflow-preventing groove 22 is also an acute angle in this embodiment.
As shown in fig. 1 to 3, the spindle head further includes a waterproof cover 5, and the waterproof cover 5 is sleeved outside the waterproof end cover 3 and the water slinger 2 and is fixedly connected to the waterproof end cover 3. The waterproof cover 5 is provided to perform a preliminary waterproof function, and reduce the amount of cooling water flowing into the drain slit 20. Preferably, the waterproof cover 5 in this embodiment has a semicircular ring shape.
As shown in fig. 2, a first seal labyrinth 32 with an L-shaped cross section is arranged between the water slinger 2 and the waterproof end cover 3, and a second seal labyrinth 33 with a Z-shaped cross section is arranged between the waterproof end cover 3 and the spindle 1, so that the mechanical sealing effect of the spindle head can be effectively improved.
As shown in fig. 2, in order to further improve the sealing performance, O-ring seals 34 are disposed between the waterproof end cap 3 and the water slinger 2, and between the shaft sleeve 4 and the main shaft 1.
As shown in fig. 2 and 3, in order to facilitate the disassembly and assembly, the waterproof cover 5 and the waterproof end cover 3, the waterproof end cover 3 and the shaft sleeve 4, and the water slinger 2 and the main shaft 1 are fixedly connected by screws.
