具体实施方式detailed description
本发明已经应用在Z9型机主起落架接头衬套更换。如图1和图2所示，本发明的一种拆除衬套的工具，其特征在于，包括扳手1、套筒2、螺杆3，其中，扳手1为一块带有螺纹开口的平板，套筒2为底部带孔的杯形件，为扳手1提供支撑，为衬套4在取出过程中提供行程空间，螺杆3通过螺纹与扳手1连接，操作时旋转扳手1，驱动螺杆3沿衬套轴向运动，将衬套4从耳片5的安装孔中拉出。根据图3，具体拆除步骤如下所示：The present invention has been applied to the replacement of the main landing gear joint bushing of the Z9 type machine. As shown in Figures 1 and 2, a tool for removing a bushing of the present invention is characterized in that it includes a wrench 1, a sleeve 2, and a screw rod 3, wherein the wrench 1 is a flat plate with a threaded opening, and the sleeve 2 is a cup-shaped piece with a hole at the bottom, which provides support for the wrench 1 and provides travel space for the bushing 4 during the removal process. The screw rod 3 is connected with the wrench 1 through threads, and the wrench 1 is rotated during operation to drive the screw rod 3 along the bushing axis. Pull the bushing 4 out of the mounting hole of the lug 5. According to Figure 3, the specific removal steps are as follows:
第一步、将螺杆3插入起落架接头衬套4孔内；The first step is to insert the screw 3 into the hole 4 of the landing gear joint bushing;
第二步、将套筒螺杆3插入螺杆3，并与耳片5贴合；The second step is to insert the sleeve screw 3 into the screw 3 and attach it to the lug 5;
第三步、将扳手1与螺杆3螺接；The third step is to screw the wrench 1 and the screw rod 3;
第四步、缓慢匀速的旋转扳手1，驱动螺杆3沿孔轴方向移动，螺杆3带动衬套4一起运动，衬套4逐渐与耳片5分离，继续旋转扳手1，直至衬套4与耳片5完全脱离。Step 4: Rotate the wrench 1 at a slow and uniform speed to drive the screw 3 to move along the hole axis. The screw 3 drives the bushing 4 to move together. The bushing 4 is gradually separated from the lug 5. Continue to rotate the wrench 1 until the bushing 4 is in contact with the lug. Sheet 5 is completely detached.
