[0002] Vertical machining centers usually have a protective cover on the outside to provide safety protection for the machining center, reduce noise, and reduce splashing of processed materials to avoid contamination of the machine tool's surrounding environment. A sliding door is provided on the protective cover to facilitate operator access.

[0003] In the prior art, commonly used double-linked door structures of vertical machining centers include a wire rope and movable pulley transmission structure, a synchronous belt and synchronous pulley transmission structure, and the like.

[0004] In the above structures: 1. The wire rope and movable pulley transmission structure has the disadvantages of high noise, heavy weight, slippage, etc. 2. Although the synchronous belt and synchronous pulley transmission structure has low noise, the synchronous belt is greatly affected by temperature, especially when the temperature is low, the synchronous belt shrinks, which makes it difficult to pull the protective door.

[0007] This solution provides a chain-sprocket double-linked door, including an active door and a driven door, the active door and the driven door are provided with sheet metal protection on the outside, and an inner track and an outer track are locked on the upper part of the sheet metal protection;

[0008] The active door is provided with an active roller, the driven door is provided with a driven roller, and both the active door and the driven door are provided with H-shaped rollers, and the active and driven doors are hung on the inner and outer tracks through the H-shaped rollers, the active rollers and the driven rollers;

[0009] A transmission sprocket is installed above the driven door, a transmission chain is connected between two groups of the transmission sprockets, the transmission chain is connected to one side of the active door, and the transmission of the transmission sprocket and the transmission chain realizes the linkage effect of the active door and the driven door.

[0010] In further explanation, one end of the transmission chain is fixed to the sheet metal protection through chain lock 1, and the other end of the transmission chain is fixed to the active door through chain lock 2.

[0011] In a preferred solution, by applying a pulling force to the active door, the linkage door can move synchronously at different speeds under the transmission of the transmission chain and the transmission sprocket.

[0012] In a further solution, the bottom of the sheet metal protection is also locked with a door track, and the bottoms of the active door and the driven door are provided with grooves, in which V-shaped rollers are installed, and the active and driven doors slide on the door track through the V-shaped rollers.

[0013] In a preferred embodiment, the active roller and the driven roller are both polyurethane rollers.

[0014] The beneficial effects achieved by the utility model using the above structure are as follows:

[0015] The sprocket and chain transmission structure has the advantages of stable structure, long service life, low maintenance cost, low noise, low friction and no slipping. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] Example 1

[0024] Please refer to Figure 1 As shown, this embodiment provides a chain-sprocket double-linked door, including an active door 1 and a driven door 2, wherein the active door 1 and the driven door 2 are provided with sheet metal protection on the outside, and an inner track 3 and an outer track 4 are locked above the sheet metal protection.

[0025] refer to Figure 1 and Figure 2 As shown, the active door 1 is provided with an active roller 5, the driven door 2 is provided with a driven roller 6, and both the active door 1 and the driven door 2 are provided with an H-type roller 7. The main and driven doors 2 are hung on the inner and outer tracks 4 through the H-type roller 7, the active roller 5 and the driven roller 6.

[0026] Furthermore, a transmission sprocket 8 is installed above the driven door 2, and a transmission chain 9 is connected between two groups of the transmission sprockets 8. The transmission chain 9 is connected to one side of the active door 1. The transmission between the transmission sprocket 8 and the transmission chain 9 realizes the linkage effect of the active door 1 and the driven door 2.

[0027] Combination Figure 1 and Figure 3 As shown, the transmission sprocket 8 is fixed on the driven door 2, and the transmission chain 9 is wound between the two sprockets. Among them, one end of the transmission chain 9 is fixed to the overall sheet metal protection through a chain lock 10, and the other end of the transmission chain 9 is fixed to the active door 1 through a chain lock 2 11.

[0028] After the entire transmission mechanism is connected, a pulling force is applied to the active door 1, and through the transmission of the transmission chain 9 and the transmission sprocket 8, the driven door 2 is linked with the active door 1. At the same time, the travel distance of the active door 1 is different from that of the driven door 2, thereby realizing the synchronous movement of the linked doors at different speeds.

[0029] It should be noted that although the embodiments of the utility model have been shown and described, for ordinary technicians in this field, without departing from the inventive purpose of the utility model, structural methods and embodiments similar to the technical scheme without creative design should all fall within the scope of protection of the utility model.
