Below the frame 2, the second automatic conveying line 52 is arranged at the opening in front of the access position of the clamp, and the second automatic conveying line 52 extends outward to connect with other clamp equipment. In this embodiment, for the convenience of use, the two automatic conveying lines are double-speed chain conveying lines.
由于夹具升降架2上设有货叉,为了夹具的平稳输送,第一自动输送线51上设有避空位,避空位设置在于货叉对应的位置,如附图5所示,下降到第一自动输送线51上的夹具升降架2的货叉能够嵌入到避空位中,使得货叉的高度与第一自动输送线51的高度一致。由于倍速链输送线是采用线性传动,现有的倍速链输送线一般采用的避空方法是设置多条输送线,但是本实施例则采用了另一种避空方法,在第一自动输送线51上设置传动换向机构。这个传动换向机构是一组换向链轮511,设置在第一自动输送线51在避空位的底部的输送线底座上,共设有两个换向链轮511,第一自动输送线51上的链轮512通过倍速链链圈与转向线轮511连接,两个换向链轮511之间采用倍速链链圈连接。在实际应用中,可以根据避空位的宽度,设置对应数量的换向链轮511,确保整个自动输送线的传动效率。Since there are forks on the clamp lifting frame 2, for the smooth conveyance of the clamps, the first automatic conveying line 51 is provided with a space avoidance position, and the space avoidance position is set at the position corresponding to the fork, as shown in FIG. The forks of the clamp lifting frame 2 on the automatic conveying line 51 can be embedded in the empty space, so that the height of the forks is the same as the height of the first automatic conveying line 51 . Since the double-speed chain conveying line adopts linear transmission, the existing double-speed chain conveying line generally adopts a method of avoiding air by setting up multiple conveying lines, but this embodiment adopts another air-avoiding method. In the first automatic conveying line 51 is provided with a transmission reversing mechanism. The transmission reversing mechanism is a set of reversing sprockets 511, which are arranged on the conveyor line base of the first automatic conveying line 51 at the bottom of the empty space. There are two reversing sprockets 511 in total. The first automatic conveying line 51 The upper sprocket 512 is connected to the steering pulley 511 through a double-speed chain ring, and the two reversing sprockets 511 are connected by a double-speed chain ring. In practical applications, a corresponding number of reversing sprockets 511 can be set according to the width of the void avoidance position to ensure the transmission efficiency of the entire automatic conveying line.
在本实施例中,设置在夹具存放架11最下方的夹具存放层111为第一夹具存放层1111。由于自动进出料组件5本身有一定高度,如果第一夹具存放层1111与地面齐平,当夹具升降架2下降到底部时,即使第一自动输送线51上设有和货叉配合的避空位,承载夹具的货叉形成的平面也会与第一夹具存放层1111存在高度差。为了使得放在第一夹具存放层1111上的夹具也能够顺畅的取出和存入,第一夹具存放层1111和地面之间设有留空层,留空层的高度与自动进出料组件5的高度配合,使得下降到自动进出料组件5上的夹具升降架2或者夹具升降架2上货叉的高度与第一夹具存放层1111的高度一致。In this embodiment, the clip storage layer 111 disposed at the bottom of the clip storage rack 11 is the first clip storage layer 1111 . Since the automatic feeding and discharging assembly 5 itself has a certain height, if the first clamp storage layer 1111 is flush with the ground, when the clamp lifting frame 2 descends to the bottom, even if the first automatic conveying line 51 is provided with an empty space that cooperates with the forks , the plane formed by the fork carrying the clamp will also have a height difference with the first clamp storage layer 1111 . In order to enable the clips placed on the first clip storage layer 1111 to be taken out and stored smoothly, a blank layer is provided between the first clip storage layer 1111 and the ground. The heights are matched so that the height of the forks on the clamp lifting frame 2 lowered onto the automatic feeding and discharging assembly 5 or the clamp lifting frame 2 is consistent with the height of the first clamp storage layer 1111 .
本发明的立体夹具库采用由多个夹具存放架并排连接组成的立体钢构,夹具存放架设有多层,能够储存大量的不同型号的夹具,占地面积却非常小,有效节省生产场地,降低生产用地的成本;夹具存放架之间均设有夹具升降架和自动进出料组件,不仅可以自动存取夹具,还可以直接与夹具装备设备对接,自动更换夹具,降低生产中的人力成本,安全可靠的同时,有效提升生产效率,十分适合在汽车生产线等需要采用大量夹具的大型生产线上使用。The three-dimensional clamp library of the present invention adopts a three-dimensional steel structure composed of a plurality of clamp storage racks connected side by side. The clamp storage racks are provided with multiple layers and can store a large number of different types of clamps, but the floor area is very small, which effectively saves production sites and reduces The cost of production land; there are fixture lifting racks and automatic feeding and discharging components between the fixture storage racks, which can not only automatically access fixtures, but also directly connect with fixture equipment to automatically replace fixtures, reduce labor costs in production, and ensure safety. While reliable, it can effectively improve production efficiency, and is very suitable for large-scale production lines that require a large number of fixtures such as automobile production lines.
