[0028] The following is combined with Figure 1 ~Attached Figure 4 The embodiments of the present utility model are described in detail.
[0029] The embodiment of the utility model provides an end hole processing device for a piston rod. The end hole processing device includes: a transport mechanism 1 for transporting the piston rod in sequence along the material taking area, the drilling area, the punching area, and the material discharging area, a drilling mechanism 2 arranged in the drilling area, and a punching mechanism 3 arranged in the punching area. The drilling mechanism 2 includes: a first positioning unit for positioning the piston rod, a tool 4 for drilling a positioning hole on the end face of the piston rod, a motor 5 for driving the tool 4 to rotate, and a first walking unit for driving the tool 4 to move. It should be understood that when both ends of the piston rod need to be processed with end holes, the tool 4 is respectively set at both ends of the piston rod; when the piston rod only needs to be processed with an end hole at one end, the tool 4 is only set at one end of the piston rod. The punching mechanism 3 includes: a second positioning unit for positioning the piston rod, a punch 6 for punching a hole on the end face of the piston rod, and a second walking unit for driving the punch 6 to move. It should be understood that when both ends of the piston rod need to be processed with end holes, punches 6 are respectively provided at both ends of the piston rod; when only one end of the piston rod needs to be processed with an end hole, only one end of the piston rod is provided with a punch 6. The transfer mechanism 1 includes: a pick-and-place unit 7 for picking up and placing the piston rod, and a third walking unit for driving the pick-and-place unit 7 to move.
[0030] The specific implementation method of the utility model is described below: the transfer mechanism 1 transfers the piston rod from the material taking area to the drilling mechanism 2 in the drilling area; the first positioning unit positions the piston rod; the first walking unit drives the tool 4 to move in the front-to-back direction, and the motor 5 drives the tool 4 to rotate, so that the positioning hole can be preliminarily drilled on the end face of the piston rod. The transfer mechanism 1 transfers the piston rod from the drilling area to the punching area; the second positioning unit positions the piston rod; the second walking unit drives the punch 6 to move in the front-to-back direction, so that the positioning hole can be further punched into the required end hole. Finally, the transfer mechanism 1 transfers the piston rod from the punching area to the discharge area. The end hole processing device is usually used in conjunction with upstream and downstream conveying devices. The upstream conveying device will send the upstream piston rod to the material taking area, and the downstream conveying device will send the piston rod in the discharge area to the downstream. The utility model firstly drills a positioning hole on the end face of the piston rod by a tool 4, and then punches a hole on the basis of the positioning hole to process the required end hole; in this way, not only the processing accuracy of the end hole can be improved, but also the collapse and concavity of the end face of the piston rod near the end hole can be avoided, thereby improving the processing quality of the end hole.

It should be understood that the fifth power source 15 is preferably a hydraulic cylinder. The fifth power source 15 drives the first clamping member 8 to move toward the second clamping member 9, so that the first clamping member 8 cooperates with the second clamping member 9 to clamp the piston rod, thereby completing the positioning of the piston rod. The top of the first support member 10 has a first limiting groove that limits the piston rod.
[0032] Further, the knife hole diameter of the first abutting member 8 is adapted to the end diameter of the piston rod. It should be understood that the knife hole diameter of the first abutting member 8 is the same as the end diameter of the piston rod, or slightly larger than the end diameter of the piston rod, and smaller than the diameter of the main part of the piston rod.

It should be understood that when the punch 6 is provided at only one end of the piston rod; the punch 6 will cooperate with the positioning pieces 16 distributed at both ends of the piston rod opposite to it to form a tight contact with the piston rod to achieve positioning; the positioning piece 16 located at the same end of the piston rod as the punch 6 is located between the punch 6 and the piston rod, and will limit the piston rod when the punch 6 exits the end hole of the piston rod. When the punch 6 is provided at both ends of the piston rod, the two positioning pieces 16 are located between the two punches 6 to limit the piston rod when the punch 6 exits the end hole of the piston rod. The top of the second support piece 17 has a second limiting groove that limits the piston rod.

In this way, the pick-and-place unit 7 can transfer multiple piston rods from the material picking area to each drilling mechanism 2, transfer multiple piston rods from each drilling mechanism 2 to each punching mechanism 3, and transfer multiple piston rods from each punching mechanism 3 to the material discharge area at one time.
