[0031] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0032] A typical implementation of the present utility model is as follows Figure 1 and Figure 2 As shown, a multi-station drilling machine includes a frame 1, a loading and unloading mechanism, a drilling mechanism and a dust collection mechanism, wherein the loading and unloading mechanism and the drilling mechanism are both arranged on the top of the frame 1.

[0033] The loading and unloading mechanism includes a loading mechanism and a unloading mechanism 8, which are arranged opposite to each other, wherein the loading mechanism includes a material platform 2, and a material lifting platform 3 is arranged on one side of the material platform 2. The height of the material platform 2 is higher than the height of the material lifting platform 3, and a plurality of material slide rails 4 are arranged between the material platform 2 and the material lifting platform 3. One end of the material slide rail 4 is connected to the material platform 2, and the other end is arranged to be tilted downward so that the end of the material slide rail 4 is located directly above the material lifting platform 3. After the material moves to the edge of one side of the material platform 2, it slides along the material slide rail 4 and finally falls onto the material lifting platform 3, thereby realizing material loading.

[0034] The material lifting platform 3 is an "L"-shaped structure, including a vertical plate and a horizontal plate. The vertical plate and the horizontal plate are vertically arranged. The vertical plate is arranged on the side of the horizontal plate away from the material platform 2. The material slides along the material slide rail 4 and falls onto the horizontal plate. The vertical plate prevents the material from sliding off the horizontal plate.

[0035] Lifting mechanisms 5 are provided at both ends of the material lifting platform 3. Both ends of the material lifting platform 3 are connected to the lifting mechanisms 5. The height of the material lifting platform 3 is controlled by the lifting mechanisms 5, so that materials of different specifications can be drilled.

[0036] Specifically, Figure 3 As shown, the lifting mechanism 5 includes a fixed frame 51, which is a "]"-shaped structure. A screw rod 52 is arranged on the fixed frame 51. Both ends of the screw rod 52 are rotatably connected to the fixed frame 51. A sliding block 53 is rotatably connected to the screw rod 52. Guide rods 54 are slidably connected to both sides of the sliding block 53. Both ends of the guide rod 54 are fixedly connected to the fixed frame 51. The top of the screw rod 52 passes through the fixed frame 51 and is fixedly connected to a hand wheel 55. By rotating the hand wheel 55, the sliding block 53 is driven up and down by the screw rod 52. The sliding block 53 is fixedly connected to the end of the material lifting platform 3, so that the lifting mechanism 5 is used to drive the material lifting platform 3 to move up and down.

[0038] The feeding mechanism also includes a material fixing mechanism 6, and a plurality of material fixing mechanisms 6 are provided. The plurality of material fixing mechanisms 6 are all arranged below the material platform 2 and are arranged opposite to the material lifting platform 3. A first sliding mechanism 7 is arranged below the material platform 2, and the first sliding mechanism 7 is fixed on the frame 1. The plurality of material fixing mechanisms 6 are all fixed on the first sliding mechanism 7, so that the material fixing mechanism 6 can slide on the frame 1.

[0039] Specifically, Figure 4 and Figure 5 As shown, the first sliding mechanism 7 includes a first slide rail 71, two first slide rails 71 are provided, the two first slide rails 71 are arranged in parallel, and multiple first sliders 72 are slidably connected to the first slide rail 71.

[0040] When preparing to drill a hole in the material, the first cylinder 61 drives the first push block 62 to move. Since the first cylinder 61 is arranged opposite to the material lifting platform 3, the first push block 62 can contact the side of the material after the telescopic end of the first cylinder 61 is extended, so that the material is clamped by using multiple first push blocks 62 and the vertical plates on the material lifting platform 3 to prevent the material from moving during drilling.

[0041] like Figure 6As shown, the unloading mechanism 8 includes multiple second cylinders 81, the telescopic ends of the multiple second cylinders 81 are fixedly connected with second push blocks 82, the bottoms of the multiple second cylinders 81 are connected to the second sliding mechanism 9 through a second connecting plate 83, and the second sliding mechanism 9 is arranged on the side of the material lifting platform 3 away from the first sliding mechanism 7, and the second sliding mechanism 9 is arranged parallel to the first sliding mechanism 7.

The size of the through hole 31 is larger than the size of the second push block 82, so that the second push block 82 can pass through the through hole 31. When unloading, the first push block 62 retracts following the first cylinder 61, and the second push block 82 extends following the second cylinder 81. The second push block 82 passes through the through hole 31 and contacts the side of the material, thereby pushing the material off the material lifting platform 3 and onto the finished product rack 10 located below the rack 1.

[0044] The drilling mechanism includes a plurality of vertical drilling mechanisms 11 and a plurality of horizontal drilling mechanisms 12. The plurality of vertical drilling mechanisms 11 are all fixed on the second sliding mechanism 9 so that the vertical drilling mechanisms 11 can slide on the frame 1.

A first drilling rig 115 is arranged on the slide 113, and the first drilling rig 115 is located directly above the material lifting platform 3. The first drilling rig 115 follows the slide 113 to perform the lifting movement, so as to drill holes in the material fixed on the material lifting platform 3.

[0045] like Figure 8As shown, multiple horizontal drilling mechanisms 12 are fixedly connected to the first sliding mechanism 7, and the first sliding mechanism 7 is used to make the multiple horizontal drilling mechanisms 12 slide on the frame 1. The horizontal drilling mechanism 12 includes a second drilling rig 121 and a linear module 122. The second drilling rig 121 is fixed on the slide 113 of the linear module 122. The movement of the second drilling rig 121 is achieved by the linear module 122. The bottom of the linear module 122 is fixed to the first slide rail 72 through a second support plate 123, thereby realizing the sliding connection between the horizontal drilling mechanism 12 and the first slide rail 71. The second drilling rig 121 is set opposite to the material lifting platform 3, and the linear module 122 drives the second drilling rig 121 to perform telescopic movement, thereby drilling the side wall of the material placed on the material lifting platform 3.

[0047] In addition, side panels are provided on both sides and the rear side of the bottom of the material platform 2. Exhaust ports 14 are provided on the side panels on both sides of the material platform 2. The exhaust ports 14 on both sides are connected to the vacuum cleaner through pipes, so that the bottom of the material platform 2 acts as a dust collecting hood.

[0048] In addition, a purge hole 15 is provided at one end of the material lifting platform 3, and a second dust collecting hood 16 is provided at the other end. The purge hole 15 is connected to the compressed air pipeline, and the second dust collecting hood 16 is connected to the dust collector through the pipeline. After the workpiece is processed, the compressed air solenoid valve is opened, and the compressed air enters the product cavity through the purge hole 15.
