具体实施方式detailed description
下面结合附图对本实用新型进行详细的说明。Below in conjunction with accompanying drawing, the utility model is described in detail.
参见图1至图11,一种侧向钻铣机床,包括床身1,所述床身1的侧面设置有用于装夹工件的旋转台装置2;所述床身1装设有纵向移动装置3,所述纵向移动装置3连接有立柱4,所述立柱4滑动连接有第一托板41和用于驱动第一托板41升降的第一驱动机构42,所述第一托板41活动连接有用于加工旋转台装置2上的工件的旋转切削装置5。本钻铣机床的工作原理是:当需要加工时,先将工件直接装夹于旋转台装置2,纵向移动装置3带动立柱4进行移动,同时,所述第一驱动机构42可以进一步驱动第一托板41进行向上或向下位移,从而使旋转切削装置5从相应的下刀位进行加工,加工内容包括:铣削表面、镗孔、攻丝及钻孔等,所述旋转切削装置5即可对工件的当前侧面进行加工,当完成当前侧面加工后,旋转台装置2旋转一定的角度,使另一加工面与旋转切削装置5对应,进而继续加工,依次最终可实现360度的侧面直接加工,这样,只需要一次装夹工件即可,明显提高了加工效率,同时,由于该旋转台装置2只对工件作旋转动作,所以,可以承载较大重量的工件加工;这种工件装夹于侧面的方式,相对传统机床来说,可以使工件的高度不受加工主轴的限制,本机床的加工行程更大。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.
如图4所示,所述纵向移动装置3包括第二托板31及用于驱动第二托板31纵向移动的第六驱动机构32,所述第二托板31采用线性导轨或矩形方轨与床身1滑动连接,所述第六驱动机构32采用伺服电机与丝杆方式,利用丝杆与第二托板31螺接,从而实现精确的纵向移动。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.
所述第一驱动机构42的作用是使第一托板41沿着立柱4上行或下行,第一驱动机构42的最佳方案是采用伺服电机与丝杆方式,利用丝杆与第一托板41螺接,从而实现精确的升降控制。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.
通常,在机加工中,往往还需要进行倾斜加工,例如:倾斜平面、倾斜导孔等,这类加工,在装夹工件时,显得更加麻烦,往往需要多个夹具或治具来辅助装夹才能使加工面对应加工主轴。在本技术方案中,利用旋转切削装置5即能较佳的解决装夹的难题,具体地,参见图4至图10,所述旋转切削装置5包括旋转托板51、方滑枕52、第二驱动机构53、第三驱动机构54和与方滑枕52滑动连接的主轴切削机构55,所述方滑枕52与旋转托板51连接,所述第二驱动机构53驱动旋转托板51旋转,所述第三驱动机构54与方滑枕52连接并驱动主轴切削机构55滑动。工作时,第二驱动机构53驱动旋转托板51进行转动,所述第一托板41设置有第一光栅角度传感器412,第一光栅角度传感器412感应旋转托板51的转动角度,当旋转托板51转动到所需倾斜角度时,主轴切削机构55即可对工件进行倾斜加工,而所述主轴切削机构55在工作时,由第三驱动机构54驱动沿方滑枕52进行移动,例如:当主轴切削机构55在铣削平面加工时,第三驱动机构54即驱动主轴切削机构55移动至方滑枕52的最左端,当主轴切削机构55在进行钻孔时,主轴切削机构55可移动在方滑枕52的中部或右端。本装置较好的解决了倾斜表面的各种加工处理,省去了辅助装夹的麻烦。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.
当然,在进行镗孔或攻丝时,主轴切削机构55需要反复的进退,作为较佳的方案,所述方滑枕52与旋转托板51滑动连接,所述旋转切削装置5还包括第四驱动机构56,所述第四驱动机构56驱动方滑枕52滑动。利用本方案,在镗孔或攻丝时,由第四驱动机构56带动整个方滑枕52作进退动作,从而减轻主轴切削机构55承受反复进退驱动的冲击。Of course, when boring or tapping, the main shaft cutting mechanism 55 needs to repeatedly advance and retreat. 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.
上述第三驱动机构54、第四驱动机构56均可直接采用伺服电机与丝杆的结构,在此不再进行一一赘述。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.
详见图5,作为第二驱动机构53的较佳方案之一:所述旋转托板51的一端设置有活动螺套511,所述第二驱动机构53包括第二伺服马达531和与第二伺服马达531连接的驱动螺杆532,所述驱动螺杆532与活动螺套511螺接。工作时,利用第二伺服马达531带动驱动螺杆532,由于活动螺套511与旋转托板51连接,所以,驱动螺杆532将旋转托板51的一端实现提升或下降,这样,旋转托板51即可实现角度旋转,对应的方滑枕52、主轴切削机构55均实现相应的角度旋转。See Fig. 5 for details, as one of the preferred solutions of the second driving mechanism 53: one end of the rotating pallet 51 is provided with a movable screw sleeve 511, and the second driving mechanism 53 includes a second servo motor 531 and a second The drive screw 532 connected to the servo motor 531 is screwed to the movable screw sleeve 511 . 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.
详见图9,作为第二驱动机构53的较佳方案之二:所述旋转托板51设置有蜗轮512,所述第二驱动机构53包括第二伺服马达531和与第二伺服马达531连接的驱动蜗杆533,所述驱动蜗杆533与蜗轮512啮合。工作时,利用第二伺服马达531带动驱动蜗杆533,由于驱动蜗杆533与蜗轮512啮合,所以,驱动蜗杆533将旋转托板51直接实现角度旋转,对应的方滑枕52、主轴切削机构55均实现相应的角度旋转。See Fig. 9 for details, as the second preferred solution of the second driving mechanism 53: the rotating pallet 51 is provided with a worm gear 512, and the second driving mechanism 53 includes a second servo motor 531 and is connected to the second servo motor 531 The driving worm 533 is engaged with the worm wheel 512 . 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.
对于本机床的进一步改进,所述第一托板41设置有旋转导槽411,所述旋转托板51设置有与旋转导槽411滑动连接的导向块;所述旋转托板51连接有锁紧抵接机构6,所述第一托板41与旋转托板51之间还设置有供锁紧抵接机构6抵接的弧形板65。旋转托板51在旋转时,沿着旋转导槽411进行旋转,当旋转到位后,锁紧抵接机构6将旋转托板51当前的位置锁定,确保加工位置的准确性。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 . When the rotating pallet 51 rotates, it rotates along the rotating guide groove 411 . When the rotation is in place, the locking abutment mechanism 6 locks the current position of the rotating pallet 51 to ensure the accuracy of the processing position.
详见图3,具体地说,所述锁紧抵接机构6包括固定座61、液压缸62、抵接斜块63和楔块64,所述固定座61与旋转托板51固定连接,所述液压缸62与固定座61连接,所述楔块64设置于液压缸62的活塞轴,所述抵接斜块63与固定座61连接并与楔块64活动配合。该限制抵接机构的工作原理是这样的:当旋转托板51旋转到位后,液压缸62伸出,楔块64伸出,楔块64的一侧与抵接斜块63相抵,楔块64的另一侧与弧形板65抵接,即实现旋转托板51当前的位置锁定;当旋转托板51需要转动时,液压缸62收缩,使抵接头与弧形板65和抵接斜块63分离,解除锁定,这样,旋转托板51即可进行旋转,结构简单,控制方便。3 for details, specifically, the locking abutting mechanism 6 includes a fixed seat 61, a hydraulic cylinder 62, an abutting inclined block 63 and a wedge 64, and the fixed seat 61 is fixedly connected with the rotating pallet 51, so The hydraulic cylinder 62 is connected with the fixed seat 61 , the wedge 64 is arranged on the piston shaft of the hydraulic cylinder 62 , and the abutting inclined block 63 is connected with the fixed seat 61 and movably cooperates with the wedge 64 . The working principle of the limiting abutment mechanism is as follows: when the rotating pallet 51 is rotated in place, the hydraulic cylinder 62 stretches out, the wedge 64 stretches out, one side of the wedge 64 is against the abutting inclined block 63, and the wedge 64 The other side of the rotating pallet abuts against the arc-shaped plate 65, which realizes the current position locking of the rotating pallet 51; when the rotating pallet 51 needs to rotate, the hydraulic cylinder 62 shrinks, so that the abutting head and the arc-shaped plate 65 and the abutting inclined block 63 separates, unlocks, and like this, rotating supporting plate 51 can rotate, simple in structure, easy to control.
