â–¡ Li Lanying, Wang Jintao, Duan Hongzhen, motorcycle engine, and the engine compartment of the scooter type, but the machining accuracy of the box is required. In the professional engine manufacturer, the equipment is mostly processed. . The machine tool has two pins for positioning and pneumatic clamping. It seems that during the machining process, the plastic deformation of the box is insufficient due to the rigidity of the load, which makes the dimensional accuracy difficult to guarantee. In order to overcome the rigidity and foot of the box and to meet the requirements of mass production, our factory has set up a kind of self-locking pneumatic auxiliary support to increase the rigidity of the box and reduce the plastic deformation of the box during machining. It has been proved by practical application that the effect is ideal. It is introduced as follows.
When it is out, the dip, the rod is moved, and the floating pin 9 rises under the elastic force of the spring 1, and its effective stroke is about 5, and the pulling rod 4 is synchronously shifted to the right with the piston rod, resulting in the action of the wedge 6 in the spring 2. Next, the frictional force is also tightly contacted with the swaying é’”9 while moving to the right, and the self-locking angle of the wedge is 68, so that the floating pin 9 can be self-locked to prevent the floating pin 9 from being pressed and lowered during machining. Due to the combined action of the springs 210, the floating pin 9 can be automatically adjusted at any height within the range of the lift 5 to form a self-locking, which is safe and reliable. Since the speed control valve is installed on the cylinder, the movement of the piston rod and the wedge 6 is ensured to be slow, so that the floating pin 9 is also slowly raised. It does not form a large impact on the workpiece that has been clamped, so it is safe and reliable; when the cylinder contracts, the piston rod moves to the left, but when it is not in contact with the floating pin 9, the pull rod 4 pulls the push rod first. 3 Move left so that the floating pin 9 is separated from the wedge 6 first, after which the piston rod is moved to the left and the floating pin 9 is lowered until the floating pin 9 is lowered to the lowest point. Thus, the floating é’” 91 pieces are separated.
7. Anti-dust bushing seal 9. Floating pin 1 spring The advantage of this auxiliary bearing is that the automatic adjustment range is large, and the self-locking can be formed at any height within the range of the lift pin 9 lift 5.
Wide range of applications, internal threads on the floating pin 9, can be connected to different posts, suitable for workpieces of different heights.
It is versatile and can be applied to many machined tooling, such as milling and other tooling, so it can be promoted as a general-purpose part in production.
The flexibility is large, the power of the floating pin 9 rises and the power of the wedge 6 self-locking are all the springs are not cylinders, so it does not form a large impact force on the workpiece, and is safe and reliable.
The two questions that should be paid attention to in the design are to deal with the sequential relationship of the piston wedge wedge motion. Prevent the cylinder from moving to the left, the floating pin 9 and the wedge 6 are involved, so that the cylinder can not be moved to the left to prevent the dust from falling into it, and the dust seal should be added.
