Move to the left; when the driving rod 11 extends out of the driving member 10 as shown in FIGS. 1 and 3, the first transmission gear 20 is driven to rotate counterclockwise as shown in FIGS. 1 and 3, so that The transmission shaft 30 and the second transmission gear 40 also rotate counterclockwise as shown in FIGS. 1 and 3, and the rack 50 is pushed by the second transmission gear 40 to the right as shown in FIG. Party mobile. Because the second transmission gear 40 and the first transmission gear 20 can rotate at the same angular velocity, and the number of the second gear teeth 41 of the second transmission gear 40 is more than that of the first transmission gear 20 The number of teeth 21 is such that the drive rod 11 only needs to be provided with the tooth portion 111 with the length L1, and the drive rod 11 can be driven with the length L2 through the first transmission gear 20, the transmission shaft 30 and the second transmission gear 40 The rack 50 has a length L2 greater than the length L1 of the tooth 111. Therefore, the short-stroke driving member 10 of the present invention can drive the rack 50 with a length L2 greater than the length L1 of the tooth portion 111.

As shown in Figure 4, one side of the tool change door assembly 60 is a tool magazine, and the other side is a processing area. The tool change door assembly 60 includes a door frame 61, a tool change door 62, a fixed frame 63, and a A transmission gear box 64, a transmission shaft cover 65 and a second transmission gear box 66. The tool change door 62 is movably coupled to the door frame 61 relative to the door frame 61, and the rack 50 is coupled to the top surface of the tool change door 62. The fixed frame 63 is installed on the door At the top of the frame 61, the driving member 10 is coupled to the outer side of the fixing frame 63, and the driving rod 11 extends into the fixing frame 63. The first transmission gear box 64 is coupled to the outer side of the fixing frame 63 away from the driving member 10, the first transmission gear 20 is disposed in the first transmission gear box 64, and the driving rod 11 extends into the first transmission gear The box 64 meshes with a plurality of first gear teeth 21 of the first transmission gear 20. The transmission shaft cover 65 is combined with the fixing frame 63 on the outer side surface of the first transmission gear box 64 and is arranged adjacent to the first transmission gear box 64. The transmission shaft 30 is provided on the transmission shaft cover 65 Inside. The second transmission gear box 66 is arranged adjacent to the transmission shaft cover 65 and is located above the knife change door 62, the second transmission gear 40 is arranged in the second transmission gear box 66, and the second transmission The gear 40 partially extends into the top end of the door frame 61 and meshes with the rack 50.

When the present invention is used in conjunction with the tool change door assembly 60, and the tool change door 62 is to be opened to connect the tool magazine with the processing area, as shown in FIGS. 4 and 5, the drive member 10 is activated to make the drive rod 11 Retract the driving member 10 to drive the second transmission gear 40 to rotate in the clockwise direction as shown in FIGS. 4 and 5, and drive the rack 50 to move to the left as shown in FIG. 5, the rack 50 drives the tool change door 62 to move to the left, so as to open the tool change door 62; when you want to close the tool change door 62 so that the tool change door 62 separates the tool magazine and the processing area, as shown in Figures 6 and 7 As shown, the driving member 10 is activated, the driving rod 11 extends out of the driving member 10, and extends out of the first transmission gear box 64, thereby driving the second transmission gear 40 counterclockwise as shown in FIGS. 6 and 7 Rotating in the direction and driving the rack 50 to move to the right as shown in FIG. 7, the rack 50 drives the tool change door 62 to move to the right, thereby closing the tool change door 62.

With the above-mentioned technical means, the present invention adds the first transmission gear 20, the transmission shaft 30, the second transmission gear 40 and the rack 50 between the drive member 10 and the tool change door 62, and the The number of the second gear teeth 41 of the second transmission gear 40 is more than the number of the first gear teeth 21 of the first transmission gear 20, and then the second transmission gear 40 is coaxial with the first transmission gear 20 It rotates with the same angular velocity. Therefore, even if the length L1 of the tooth portion 111 of the driving rod 11 is less than the length L2 of the rack 50, the tool change gate 62 can still be driven to move the same stroke as the length L2 of the rack 50, So this new model It is sufficient to use a pneumatic cylinder with a short stroke as the driving member 10. The driving part 10 of the present invention is matched with the transmission gears 40 and 20 with different numbers of gear teeth 41 and 21. Therefore, a pneumatic cylinder with a short stroke can be used as the driving part 10 to drive the tool change gate 62 with a longer moving stroke. Compared with the existing tool change door drive device, it saves space and cost.
