detailed description

Below in conjunction with accompanying drawing, the utility model is described in detail.

Referring to Fig. 1 to Fig. 11, a lateral drilling and milling machine tool includes a bed 1, the side of the bed 1 is provided with a rotary table device 2 for clamping workpieces; the bed 1 is equipped with a longitudinal movement device 3. The vertical moving device 3 is connected with a column 4, and the column 4 is slidably connected with a first supporting plate 41 and a first driving mechanism 42 for driving the first supporting plate 41 up and down, and the first supporting plate 41 is movable A rotary cutting device 5 for machining workpieces on the rotary table device 2 is connected. The working principle of this drilling and milling machine tool is: when processing is required, the workpiece is first directly clamped on the rotary table device 2, and the longitudinal moving device 3 drives the column 4 to move. At the same time, the first driving mechanism 42 can further drive the first The supporting plate 41 is displaced upward or downward, so that the rotary cutting device 5 can process from the corresponding lower tool position. The processing content includes: milling surface, boring, tapping and drilling, etc., and the rotary cutting device 5 can The current side of the workpiece is processed. After the current side processing is completed, the rotary table device 2 rotates at a certain angle, so that the other processing surface corresponds to the rotary cutting device 5, and then continues processing. Finally, 360-degree direct side processing can be realized in turn. In this way, it is only necessary to clamp the workpiece once, which obviously improves the processing efficiency. At the same time, because the rotary table device 2 only rotates the workpiece, it can carry a relatively heavy workpiece for processing; this kind of workpiece is clamped in Compared with the traditional machine tool, the side method can make the height of the workpiece not limited by the machining spindle, and the machining stroke of this machine tool is larger.

As shown in Figure 4, the longitudinal movement device 3 includes a second pallet 31 and a sixth drive mechanism 32 for driving the second pallet 31 to move longitudinally, and the second pallet 31 adopts a linear guide rail or a rectangular square rail Slidingly connected with the bed 1, the sixth driving mechanism 32 adopts a servo motor and a screw, and is screwed with the second supporting plate 31 by the screw, so as to realize precise longitudinal movement.

The function of the first driving mechanism 42 is to make the first supporting plate 41 go up or down along the column 4, and the best solution for the first driving mechanism 42 is to adopt the servo motor and the screw mandrel mode, and utilize the screw mandrel and the first supporting plate 41 screw connection, so as to achieve precise lifting control.

Usually, in machining, it is often necessary to perform inclined processing, such as: inclined plane, inclined guide hole, etc. This type of processing is more troublesome when clamping the workpiece, and often requires multiple fixtures or fixtures to assist clamping Only then can the processing surface correspond to the processing spindle. In this technical solution, the problem of clamping can be better solved by using the rotary cutting device 5. Specifically, referring to FIGS. The second driving mechanism 53, the third driving mechanism 54 and the main shaft cutting mechanism 55 slidingly connected with the square ram 52, the square ram 52 is connected with the rotating pallet 51, and the second driving mechanism 53 drives the rotating pallet 51 to rotate , the third driving mechanism 54 is connected with the square ram 52 and drives the spindle cutting mechanism 55 to slide. When working, the second driving mechanism 53 drives the rotating pallet 51 to rotate, and the first pallet 41 is provided with a first grating angle sensor 412, and the first grating angle sensor 412 senses the rotation angle of the rotating pallet 51. When the plate 51 rotates to the required angle of inclination, the spindle cutting mechanism 55 can perform tilting processing on the workpiece, and the spindle cutting mechanism 55 is driven by the third driving mechanism 54 to move along the square ram 52 when it is working, for example: When the spindle cutting mechanism 55 was processing on the milling plane, the third driving mechanism 54 promptly drove the spindle cutting mechanism 55 to move to the leftmost end of the square ram 52, and when the spindle cutting mechanism 55 was drilling, the spindle cutting mechanism 55 could move in the The middle part or the right end of square ram 52. The device preferably solves various processing of the inclined surface, and saves the trouble of auxiliary clamping.

As a better solution, the square ram 52 is slidingly connected with the rotating pallet 51, and the rotating cutting device 5 also includes a fourth The driving mechanism 56, the fourth driving mechanism 56 drives the square ram 52 to slide. With this solution, when boring or tapping, the fourth driving mechanism 56 drives the entire square ram 52 to move forward and backward, thereby reducing the impact of the spindle cutting mechanism 55 from repeatedly driving forward and backward.

Both the third driving mechanism 54 and the fourth driving mechanism 56 mentioned above can directly adopt the structure of a servo motor and a screw rod, and details will not be repeated here.

During work, utilize the second servo motor 531 to drive the driving screw 532, because the movable screw sleeve 511 is connected with the rotating pallet 51, so the driving screw 532 will realize lifting or lowering of one end of the rotating pallet 51, like this, the rotating pallet 51 is Angular rotation can be realized, and the corresponding square ram 52 and spindle cutting mechanism 55 can realize corresponding angular rotation.

When working, the second servo motor 531 is used to drive the driving worm 533. Since the driving worm 533 is meshed with the worm wheel 512, the driving worm 533 will directly rotate the rotating pallet 51 to achieve angular rotation, and the corresponding square ram 52 and the main shaft cutting mechanism 55 are all achieve the corresponding angular rotation.

For the further improvement of this machine tool, the first supporting plate 41 is provided with a rotating guide groove 411, and the rotating supporting plate 51 is provided with a guide block slidingly connected with the rotating guiding groove 411; the rotating supporting plate 51 is connected with a locking The abutment mechanism 6 is further provided with an arc-shaped plate 65 for the abutment of the locking abutment mechanism 6 between the first supporting plate 41 and the rotating supporting plate 51 .

2 for details, specifically, the first counterweight mechanism 71 includes a bracket 711, a front pulley 712, a rear pulley 713, a counterweight 714 and a counterweight rope 715, and the rotary cutting device 5 is located in front of the column 4 , the counterweight 714 is located behind the column 4, the front pulley 712 and the rear pulley 713 are connected to the bracket 711, one end of the counterweight rope 715 is connected to the rotary cutting device 5, and the counterweight rope 715 is The other end passes through the front pulley 712 and the rear pulley 713 in sequence and is connected with the counterweight 714 . As an optimum, the counterweight 714 is preferably slidably connected with the column 4, thereby improving safety and stability. The structure of the second counterweight mechanism 72 is the same as that of the first counterweight mechanism 71. When the rotating pallet 51 rotates clockwise, the rotating pallet 51 pulls the counterweight 714 of the first counterweight mechanism 71 upwards, and the second The counterweight of the counterweight mechanism 72 is downward; when the rotating pallet 51 rotates counterclockwise, the counterweight 714 of the first counterweight mechanism 71 is pulled by the rotating pallet 51 downward, and the counterweight of the second counterweight mechanism 72 Upward; under the action of two counterweights, the counterweight balance is realized to ensure the stability of processing.
