Problems solved by technology

[0006] The patented solution seems to be able to process two parallel holes, and it can basically be realized for small medium cylinders, but for large medium cylinders, its cross-section is 0.25m 2 , the length can reach 1m, it is difficult to achieve the effect of reducing the amount of eccentricity if the weight is only used to balance its gravity
On the other hand, for large medium cylinders, the fixing mechanism needs to have sufficient strength, and the accuracy of dim

Example Embodiment

[0045] Example 1

[0046] Combine figure 2 In this embodiment, a method for processing the inner cavity of a piston in a cylinder body uses a cylinder fixing mechanism to process the inner cavity of the piston. The cylinder fixing mechanism is connected to the support plate 11 on the turning shaft 12 of the lathe, and the cylinder is fixed The mechanism includes a connecting plate 21, a side wall baffle 31 and a pallet 41 that are vertically fixed to each other, that is, the side wall baffle 31 and the pallet 41 are both perpendicular to the connecting plate 21 and fixedly connected to the connecting plate 21, such as figure 2 As shown in the figure, the supporting plate 41 is horizontally arranged, the side wall baffle 31 is vertically arranged, and the lower end of the side wall baffle 31 is fixedly connected to the supporting plate 41. The middle section of the supporting plate 41 passes through the axis of the rotating shaft 12, and two side wall baffles 31 are symmetrically...

Example Embodiment

[0050] Example 2

[0051] The basic structure of the cylinder fixing mechanism in this embodiment is the same as that of the first embodiment. The difference is that four end face reference blocks 23 are provided on the connecting disk 21, and the end face reference blocks 23 are at the same distance from the axis of the rotating shaft 12 , The end face reference blocks 23 are distributed at equal intervals along the circumferential direction, that is, the central angle between two adjacent end face reference blocks 23 is 90°.

[0052] A bottom reference block 43 is provided on the upper surface of the pallet 41, such as figure 2 As shown in the figure, the bottom reference block 43 is arranged in two rows along the length of the pallet, and the position of the bottom reference block 43 corresponds to the position of the pressure plate 33 up and down. When the pressure plate 33 is used to apply a pressing force, the lower part of the middle cylinder is covered by the bottom surface...

Example Embodiment

[0057] Example 3

[0058] The basic structure of the cylinder fixing mechanism in this embodiment is the same as that in embodiment 2, and the difference is: Figure 5 In this embodiment, a reinforcing bolt 24, a first rib 34 and a second rib 38 are provided between the side wall baffle 31 and the connecting plate 21, and the second rib 38 is perpendicular to the side wall baffle 31; The plate 34 is connected to the side where the screw 32 on the side wall baffle 31 is located. The first rib 34 and the second rib 38 fix the side wall baffle from different directions. The height of the second rib 38 from the supporting plate 41 is greater than the height of the piston hole axis relative to the supporting plate 41, which is closer to the overall structure The support strength is higher in the central position of the machine.

[0059] In order to reduce the overall weight, the side wall baffle 31 is provided with a first weight reduction hole 39, such as Image 6 As shown, the first ...

Abstract

The invention discloses a method for processing a piston inner cavity of a middle cylinder and belongs to the field of quartering hammer processing. The method comprises the steps as follows: firstly, a piston hole and an oil inflow hole are drilled on a boring machine; then, a middle cylinder fixing mechanism is used for location and fixing to guarantee that the middle cylinder is attached to the datum plane; next, static balance debugging is performed for processing; the piston hole is processed firstly, a valve hole and a step surface hole are then processed, and the oil inflow hole and an oil outflow hole are processed with a special tool on a lathe tool shaft bar. The piston inner cavity of the middle cylinder is processed in cooperation with a high-strength cylinder fixing mechanism, the weight of the middle cylinder can be balanced, and the processing precision is high; by means of the processed oil holes, the performance of the middle cylinder can be further improve, and accordingly, the processing quality is greatly improved.

Description

technical field [0001] The invention relates to the technical field of breaking hammer processing, and more specifically, relates to a processing method for a piston inner cavity of a middle cylinder body. Background technique [0002] Breaking hammer is a kind of hydraulic energy as power to drive the piston inside the upper cylinder of the hydraulic cylinder to reciprocate, and hammer the drill rod through the piston to transmit energy to the drill rod, and the energy on the drill rod is then It is an important construction machinery that is absorbed by the hit object and crushed by the hit object. It is mainly used for crushing, demolition, and excavation of hard layers in construction. It is usually installed on excavators, loaders or power stations. It has the advantages of strong impact, convenient use, good maneuverability and high efficiency. With the development of hydraulic technology, hydraulic breakers are more and more widely used in all walks of life in societ...
