Description

Technical Field

[0002] The horizontal machining center is one of the most commonly used CNC machine tools. The horizontal machining center mainly controls the basic movement of the machine tool through the CNC system and servo drive device. The main feature of its structure is that the spindle is set horizontally. An automatic exchange workbench is set on the horizontal machining center to form a flexible manufacturing unit, which realizes automatic exchange of workpieces, that is, another workpiece can be loaded and unloaded while processing.

[0032] During specific use, through the arrangement of the first slide groove 21, the second slide groove 22, the first slider 23, the second slider 24 and the screw 25, when a sudden power outage causes the machine body 1 to stop operating, the screw 25 is rotated to drive the first slider 23 to move downward on the inner wall of the first slide groove 21 while driving the workbench 2 and the second slider 24 to move downward, thereby separating the workpiece from the tool and thus avoiding the situation where the machine body 1 operates too fast and collides with the workpiece when power is received, thereby colliding with the tool and damaging the tool, thereby facilitating the separation of the tool from the workpiece and facilitating the re-operation of the machine body 1.

[0039] Working principle: In use, most of the existing horizontal machining centers use pneumatic clamping or claw clamping.

This is inconvenient to use. If the pressure value of the pneumatic clamping is not set accurately, it will also cause damage to the workpiece during the clamping process, thereby increasing the cost of use and inconvenience. When the workpiece needs to be processed, the workpiece is placed in the limit groove 6 and then limited once, and the first push plate 13 and the second push plate 14 are pushed to drive the two to move in the opposite direction, thereby driving the first arc clamping block 10 and the second arc clamping block 11 to rotate in the opposite direction on the outer surface of the fixed rod 12, thereby clamping the workpiece for a second time and passing The setting of the serrations 18 can improve the friction and stability of clamping, and then the limit rod 16 is screwed into the first through hole 15 and the second through hole 17, so as to limit and fix the position of the first push plate 13 and the second push plate 14, and then the mechanical clamping method can avoid the workpiece from falling due to a sudden power outage outside, thereby avoiding the situation of hitting the tool, and the clamping stability is good and the workpiece is prevented from loosening and hitting the tool. It is easy to use and clamp. When the power is suddenly cut off and the machine body 1 does not operate, the screw 25 is rotated to drive the first slider 23 to move downward on the inner wall of the first slide groove 21, and at the same time drive the workbench 2 and the second slider 24 to move downward, thereby separating the workpiece from the tool, thereby avoiding the situation that the machine body 1 operates too fast and collides with the workpiece when power is received, thereby colliding with the tool and damaging the tool, thereby facilitating the separation of the tool from the workpiece and facilitating the re-operation of the machine body 1.
