Description

Technical Field

[0001] The utility model relates to the technical field of plunger processing, in particular to a plunger end drilling device which is easy to process. Background Art

[0002] A plunger is a mechanical component, typically cylindrical in shape. In hydraulic systems, it's often used in devices like hydraulic cylinders and plunger pumps, transferring and converting energy through reciprocating motion. For example, in a plunger pump, the plunger's movement generates pressure, moving fluid from a low-pressure area to a high-pressure area.

[0003] During the processing of plungers, it is usually necessary to drill a hole at the end of the plunger to facilitate connection with an external connector. When drilling the end of some large plungers, due to the heavy weight of the plunger, it takes a lot of physical strength for the operator to stand the plunger upright on the drilling machine by manpower. There is also a risk of the plunger tipping over, which can easily injure the operator. Therefore, we proposed a plunger end drilling device that is easy to process to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the defects in the prior art that erecting the plunger on the drilling machine by manpower requires a large amount of physical strength of the operator, and there is also a risk of the plunger tipping over, which can easily injure the operator. The utility model provides a plunger end drilling device that is easy to process.

[0005] The utility model is achieved through the following technical solutions:

[0008] In a preferred embodiment of the present invention, a slot is provided at the outer end of the support seat, and a roller is provided in the slot. The top end of the roller is flush with the upper surface of the support seat. When the plunger is erected, the bottom end of the plunger is guided by the roller to facilitate its erection.

[0009] In a preferred embodiment of the present invention, the number of the first hydraulic cylinders on each side is more than two, and the telescopic ends of the first hydraulic cylinders on each side are fixedly connected to the same clamping seat, thereby improving the stability of the clamping seat during movement and operation.

[0010] In a preferred embodiment of the present invention, the distances between the clamping seats and the support seats on both sides are equal, and V-shaped grooves are provided on the sides of the clamping seats that are close to each other.

To facilitate the erection of the plunger, a groove is provided at the outer end of the support seat 3. A roller 31 is provided in the groove. The top end of the roller 31 is flush with the upper surface of the support seat 3. When the plunger is erected, the roller 31 guides the bottom end of the plunger to facilitate its erection.

[0020] Among them, mounting seats 4 are fixed on both sides of the support seat 3, the mounting seats 4 are fixedly connected to the drilling machine body 1, and a rotating plate 5 is installed on the outer end of the mounting seat 4, one end of the rotating plate 5 is rotatably connected to the mounting seat 4, and the rotating plate 5 rotates up and down. At the same time, a first hydraulic cylinder 6 is fixed to the outer end of the rotating plate 5, and the telescopic end of the first hydraulic cylinder 6 passes through the rotating plate 5, and a clamping seat 7 is fixed to the telescopic end of the first hydraulic cylinder 6. The number of first hydraulic cylinders 6 on each side is more than two, and the telescopic end of the first hydraulic cylinder 6 on each side is fixedly connected to the same clamping seat 7, thereby improving the stability of the clamping seat 7 when moving and working;

[0021] It is important to note that;

[0022] 1. The distances between the clamping seats 7 and the support seats 3 on both sides are equal, and a V-shaped groove 71 is provided on the side of the clamping seats 7 close to each other. The setting of the V-shaped groove 71 facilitates clamping the plunger to prevent it from moving up and down;

[0023] 2. The rotation connection of the rotating plate 5 and the center of the support base 3 are on the same straight line, so that after the rotating plate 5 is vertical, the plunger is vertical on the support base 3;
