The structure and working principle of the direct-action type kicker The direct-action type kicker device is mainly composed of a feeding head, a connecting sleeve, a connecting body, a piston, a cylinder block, a thrust bearing and the like (such as 1), and the lower part is combined with the connecting plate and the bracket. As one unit, it is fixed on the saddle between the front and rear tool holders (such as 2). The working principle is as follows: when the oil pump is turned on, the spindle rotates, the clamp is released, and then the robot feeds and the feeder moves vertically downwards, and when the workpiece is sent to the spring chuck position (feeding in position), the stroke switch is pressed, and the solenoid valve is obtained. Electric, kicker feed, send the workpiece into the chuck, the clamp is clamped, the delay is 0.4s, the solenoid valve is reversed, the kicker is returned to the original position, after 0.5s, the manipulator is reset, and then the modified kick-type kick 1. Feeding head 2. Thrust bearing 3. Connecting sleeve 4. Screw 5. Connecting body 6. Piston 7. Cylinder front and rear tool holders are fed at the same time, respectively chamfering and turning end face machining, while the feeder is reset . When the tool holder reaches the end point, it hits the grounding switch, and when the tool holder is quickly retracted, the stroke switch is pressed separately to release the clamp, that is, to enter the next cycle.
Electrical Control In terms of electrical control, programmable PLC software was designed to meet the process of railway roller machining. The specific situation is shown as 3.
In addition, the newly modified kicking device is based on air supply from the air compressor station as a kicking power. In order to eliminate water vapor in the air, a set of oil mist filtering device is also provided. At the same time, the hydraulic system has also been modified accordingly.
Points to note when designing the direct-action kicker: The direct-action type kicker shown in Figure 1 should pay attention to the following points: (1) Under normal circumstances, a concave groove with a depth of less than 1 mm is usually made on the cylinder head. The air holes are connected to avoid the air pressure being less when the piston is in contact with the cylinder. (2) Since the workpiece is rotated at a high speed, the length L of the feed head rod at the front end of the feeder is slightly larger than L1, and is basically maintained at a gap of 0.5 mm to ensure flexible rotation of the feeder head with the workpiece. (3) One end of the connecting rod connected to the connecting sleeve shall not be allowed to die on the screw of the feeding head, otherwise the feeding head will be tightened and cannot rotate flexibly with the workpiece.
A thrust bearing must be installed at the feed head to withstand the axial load of the feeder. At the center A of the end face of the feeding head, there should be a taper hole with a diameter of 5 to 6 mm and a depth of about 3 mm to avoid the end face protruding point left by the previous process, thereby ensuring that the feeding head is accurately fed into the workpiece.
After the implementation of the effect transformation, the CZ9206 bearing ferrule automatic lathe has been put into production for more than a year. The machine is reliable in operation, which not only expands the scope of use of the machine tool, but also exerts the performance of the CZ9206 machine tool to a greater extent, ensuring the various processes of the railway roller. The indicators met the requirements and created considerable economic benefits. Nowadays, the unit has been transformed into three units to improve production efficiency and create higher production value.
