The housing 300 can limit the movement of the left slider 610 and the right slider 620 in the up and down directions, so that the left slider 610 and the right slider 620 can only slide in the horizontal direction.
[0044] In combination with the above embodiments, the use principle and working process of the embodiments of the present invention are as follows:
[0045] In the initial state, the left slider 610 and the right slider 620 of the slider structure 400 are in contact, so that the first threaded half hole 616 on the left slider 610 and the second threaded half hole 622 on the right slider 620 are matched to form a threaded hole, and the switching assembly is in the first working state. At this time, the driving motor 100 is turned on to make the threaded hole of the slider structure 400 match the threaded portion 710 on the rotating rod 700, so that the threaded transmission of the slider structure 400 and the rotating rod 700 can be realized. In this working state, the processing speed is slow and the precision is high. When it is necessary to increase the moving speed of the slider structure 400, the driving motor 100 is stopped, and then the first motor 410 is controlled to be turned on and the second motor 420 is turned off, so that the driving shaft 520 of the first motor 410 rotates to drive the left sliding member 530 to rotate. The rotation of the left sliding member 530 can make the left sliding member 530 and the right sliding member 550 move oppositely, so that the left sliding member 530 moves to the left and the right sliding member 550 moves to the right, thereby realizing the disengagement of the first threaded half hole 616 and the second threaded half hole 622 from the threaded portion 710. The leftward movement of the left sliding member 530 drives the driving plate 510 to move leftward, and the sliding plate 513 on the driving plate 510 first pushes the left sliding block 610 to move leftward; the right sliding member 550 moves rightward, driving the annular protrusion 560 and the right sliding block 620 to move rightward synchronously, so that the limiting plate 617 on the left sliding block 610 gradually no longer blocks the annular protrusion 560; when the left sliding block 610 and the right sliding block 620 move to be stopped by the base 200, the left sliding block 610 and the right sliding block 620 no longer move horizontally, and the annular protrusion 560 is located above the rotating rod 700 at this time, and the driving motor 100 is started to make the rack portion 720 of the rotating rod 700 face upward; at this time, the driving plate 510 will continue to move leftward, driving the sliding plate 513 thereon to slide along the inclined groove 611 on the left sliding block 610, so that the driving plate 510 slides to the left side while When the left slider 530 moves downward, the driving plate 510 moves downward, driving the left slider 530 and the first motor 410 to move downward along the left slider 610. The left slider 530 moves downward and synchronously drives the right slider 550 and the second motor 420 to move downward along the right slider 620. When the driving plate 510 moves downward to a position where its lower end is stopped by the limit groove 618, the driving plate 510 stops moving downward. At this time, the annular protrusion 560 on the right slider no longer moves downward, and the rotating teeth on the annular protrusion 560 just mesh with the rack portion 720. Finally, the first motor 410 and the second motor 420 are synchronously driven to make the left slider 530 and the right slider 550 rotate synchronously in the same direction, so that the rotating teeth are gear-driven on the rack portion 720, thereby realizing the gear-driven transmission of the slider structure 400 as a whole on the rotating rod 700. This has a fast moving speed and high processing efficiency.
[0046] The industrial machine tool guide rail of the present invention allows the operator to timely adjust the working state of the switching component according to the processing requirements of the machine being processed, thereby improving the overall processing efficiency and precision. For example, the operator can first switch to the gear transmission mode, quickly move the slider structure 400 to the vicinity of the specified position, and then switch to the thread transmission mode for fine adjustment, which can ensure both processing efficiency and processing precision.
[0047] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0048] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
