2. BACKGROUND 背景
A. These clips and blocks are used to hold bolts and studs to band clamps to give support to brackets and other supports, to hold electrical conduits and hydraulic tubes along large cylindrical members of landing gear and other airplane components.
这些卡子和块用于将螺栓和螺柱固定在卡箍上，以支撑支架和其他支撑物，并沿起落架和其他飞机部件的大型圆柱构件固定电线导管和液压管。
B. These procedures will help prevent broken clips during service.
这些程序有助于防止使用期间卡子断裂。
3. MATERIALS AND EQUIPMENT 材料和设备
A. Fixture block — Locally made (See Figure 1)
固定块——当地制造（见图1）
B. Shim stock — 0.050 inch thick, 0.650 inch wide
垫片——厚0.050英寸，宽0.650英寸
C. Clips — BACC15AN or equivalent, as used in actual installation
卡子——BACC15AN或同等产品，实际安装中使用
D. Blocks — BACB19F or equivalent, as used in actual installation
块——BACB19F或同等产品，实际安装中使用
E. Bolts or studs — As used in actual installation
螺栓或螺柱——实际安装中使用
F. Clamp — As used in actual installation
卡箍——实际安装中使用
4. PROCEDURE 程序
A. Get or make a fixture block with a vertical hole in it to fit the bolt or stud (Figure 1).
获取或制作一个带有垂直孔的固定块，以适合螺栓或螺柱（图1）。
B. Method 1 — Standard clip position (Figure 2)
方法1——标准卡子位置（图2）
(1) Turn the clip to put its tabs up.
转动卡子，使其卡舌朝上。
(2) Put the block on the bolt with the channel toward the bolt head.
将固定块放在螺栓上，槽口朝向螺栓头。
(3) Slide this unit into the clip from the side.
从侧面将此组件滑入卡子。
(4) Slide the band of the clamp between the block and the clip.
将卡箍的带子滑入块和卡箍之间。
(5) Slide the piece of shim stock between the band and the clip. This will make a gap in the stackup, to let the finished clip slide easily on the band.
将垫片滑入带子和卡子之间。这会在叠层中形成间隙，使完成的卡箍能够轻松地在带子上滑动。
(6) Put this assembly on the work surface with the bolt shank up.
将此组件放在工作台上，螺栓柄朝上。
(7) Carefully pre-bend the clip tabs to approximately 45 to 60 degrees from vertical, to make it easier for the fixture block to bend the tabs down.
小心地将卡舌预弯至与垂直方向成大约45至60度，以便夹具块更容易将卡舌向下弯曲。
(8) Put the fixture block down on the assembled parts with the bolt shank into the hole in the fixture block.
将夹具块放在组装好的零件上，将螺栓柄插入夹具块的孔中。
(9) With a hammer, lightly tap on the fixture block until the clip tabs are bent down over the block, and nearly touch in the middle.
用锤子轻轻敲击夹具块，直到卡舌向下弯曲，几乎与夹具块中间接触。
(10) Remove the fixture block and, with pliers, carefully squeeze the clip tabs down, to start them towards the flush position.
取下固定块，用钳子小心地将卡舌向下挤压，使其开始向齐平位置移动。
(11) Pull out the piece of shim stock.
拉出垫片。
(12) With pliers, carefully squeeze the clip tabs until they touch in the middle and are flush with each other. Do not let the clip tabs overlap each other.
用钳子小心挤压卡舌，直到它们在中间接触并相互齐平。不要让卡舌相互重叠。
(13) Do this procedure again as necessary to install the remaining clips, blocks and bolts on the clamp.
如有必要，重复此步骤，将剩余的卡子、块和螺栓安装到卡箍上。
C. Method 2 — Optional clip position (Figure 3)
方法 2——可选卡子位置（图 3）
(1) Turn the clip to put its tabs up.
转动卡子，使其卡舌朝上。
(2) Slide the block, channel side up, into the clip from the side, then put the bolt down through the clip and block until the bolt head is down against the bottom of the channel in the block.
将块从侧面滑入卡子，槽口朝上，然后将螺栓穿过卡子和块，直到螺栓头抵住块中槽的底部。
(3) Put this assembly on top of the fixture block, with the bolt shank down into the hole in the fixture block.
将此组件放在夹具块顶部，螺栓柄向下插入夹具块的孔中。
(4) Slide the band of the clamp under the tabs of the clip and down on top of the bolt head and adjacent block surfaces.
将卡箍带滑到夹子的卡舌下方，并滑到螺栓头和相邻的块表面上方。
(5) Slide the piece of shim stock under the tabs of the clip and on top of the band of the clamp. This will make a gap in the stackup, to let the finished clip slide easily on the band.
将垫片滑入卡子的卡舌下方，并放在卡箍的带子上方。这样会在叠层中留出空隙，使完成的卡子能够轻松地在带子上滑动。
(6) With a hammer, carefully bend each tab of the clip down over the shim stock until the tabs almost touch in the middle.
用锤子小心地将卡子的每个卡舌向下弯曲，使其覆盖在垫片上，直到卡舌几乎碰到中间。
(7) With pliers, carefully squeeze the clip tabs down, to start them towards the flush position.
用钳子小心地将卡箍的卡舌向下压，使其开始向齐平位置移动。
(8) Pull out the piece of shim stock.
拉出垫片。
(9) With pliers, squeeze the clip tabs until they touch in the middle and are flush with each other. Do not let the clip tabs overlap each other.
用钳子挤压卡舌，直到它们在中间接触并相互齐平。不要让卡舌相互重叠。
(10) Do this procedure again as necessary to install the remaining clips, blocks and bolts on the clamp.
根据需要重复此步骤，将剩余的卡子、块和螺栓安装在卡箍上。
