Embodiment 1

[0056] combine figure 2 , the anti-deformation car-grinding method of the inner cavity of the cylinder in this embodiment, the cylinder body 6 is fixed by the cylinder body fixing mechanism during machine tool processing, and the grinding support device is used for auxiliary support during the grinding process. combine Figure 15 , the specific processing process is:

[0057] 1) Process the outer surface of the middle cylinder body blank to the required size, then fix the middle cylinder body blank on the boring machine table, initially drill the piston hole 61; then adjust the angle, and process the oil inlet hole 63 to the required size.

[0058] 2) Hoist the middle cylinder body into the cylinder body fixing mechanism, place it on the bottom surface reference block 43, and make the inner end of the middle cylinder body stick to the end surface reference block 23, and pre-tighten the middle cylinder body through the fastening bolt 37. The side sticks to the side wall refe...

Embodiment 2

[0088] The basic structure of the cylinder fixing mechanism in this embodiment is the same as that in Embodiment 1, the difference is that four end face reference blocks 23 are arranged on the connection plate 21, and the distance between the end face reference blocks 23 and the axis of the rotating shaft 12 is the same , the end face reference blocks 23 are equally spaced along the circumferential direction, that is, the central angle between two adjacent end face reference blocks 23 is 90°.

[0089] The upper surface of the supporting plate 41 is provided with a bottom reference block 43, such as figure 2 As shown in , the bottom reference block 43 is arranged in two rows along the length direction of the pallet, and the position of the bottom reference block 43 and the position of the pressure plate 33 correspond up and down. When the pressing force is applied by the pressure plate 33, the bottom of the middle cylinder is Supported by the reference block 43, the point of a...

Embodiment 3

[0095] The basic structure of the cylinder fixing mechanism in this embodiment is the same as that of Embodiment 2, the difference is that: Figure 5 , in the present embodiment, a reinforcement bolt 24, a first rib 34 and a second rib 38 are arranged between the side wall baffle 31 and the connection plate 21, and the second rib 38 is perpendicular to the side wall baffle 31; the first rib The plate 34 is connected to the surface where the screw rod 32 is located on the side wall baffle plate 31 . The first rib 34 and the second rib 38 fix the side wall baffle from different directions, and the height of the second rib 38 from the supporting plate 41 is greater than the height of the axis of the piston hole relative to the supporting plate 41, which is closer to the overall structure The central position, the support strength is higher.

[0096] In order to reduce the overall weight, the side wall baffle 31 is provided with a first lightening hole 39, such as Image 6 As sh...

Abstract

The invention discloses an anti-deformation turning and grinding machining method for a cylinder block inner cavity and belongs to the field of machining of breaking hammers. The machining method comprises the steps of drilling a piston hole and an oil inlet hole on a boring machine; conducting positioning and fixing through a middle cylinder block fixing mechanism to guarantee the fit degree of a cylinder block and a datum plane; conducting static balance adjustment to make preparation for machining; machining the piston hole, a valve hole and step holes in sequence; machining an oil inlet and an oil outlet with a special tool on a lathe tool shaft lever; and finally conducting grinding machining on the piston hole of the cylinder block inner cylinder under auxiliary supporting of a grinding supporting device. According to the method, auxiliary fixing is conducted on the middle cylinder block through multiple devices so that turning and grinding errors of the middle cylinder block can be reduced, the machining precision can be effectively improved, and the use performance of the middle cylinder block can be improved. Accordingly, the machining 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 deformation-resistant turning and grinding processing method for a cylinder inner cavity. 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...
