Embodiment 1

[0048] combine Figure 5 , Figure 6 , a welding and assembling method of the side plate of the breaker in this embodiment, the side plate is bent and flattened by the flattening mechanism 4, and the welding and assembly process of the side plate is performed by the welding fixing mechanism 2. Wherein, the compacting mechanism 4 comprises a compacting cylinder 41, an upper bracket 42 and a compacting platform 45, the upper bracket 42 is supported above the compacting platform 45 by a briquetting guide rod 43, and the compacting cylinder 41 is vertically fixed on the upper bracket 42, the piston rod of the pressing cylinder 41 is connected with the pressing block body 44, the lower surface of the pressing block body 44 is flat, and the side plate 13 can be bent or flattened by using the cushion block 46 and the rectangular pressing rod 47. operate. Such as Figure 5 As shown, a rectangular pressing bar 47 is placed on the lower side of the side plate 13, the side plate 13 is...

Embodiment 2

[0054] The improvement of the method for welding and assembling the side plate of the breaking hammer in this embodiment is that a collar 24 is arranged on the outer wall of the box body 21, and the inner diameter of the collar 24 is equal to the size of the through hole 23, and is in line with that of the through hole 23. The through holes 23 are arranged coaxially. The box body 21 can be set as a hollow structure, and the collar 24 can increase the structural strength. After being installed in the positioning shaft, it can play a main supporting role, and the through hole 23 will not be deformed after long-term use. In this embodiment, the distance between the baffle plate 24 and the positioning plate 22 is 1.4 times the thickness of the side plate 13 of the hammer.

Embodiment 3

[0056] The improvement of the method for welding and assembling the side plate of the breaker in this embodiment is that a collar 24 is provided on the outer wall of the box body 21, the inner diameter of the collar 24 is smaller than the size of the through hole 23, and the collar 24 can Put it into the through hole 23 and weld it to the inner wall of the through hole 23 . In this embodiment, the positioning shaft is directly supported by the collar 24, which has high structural strength. The distance between the baffle plate 24 and the positioning plate 22 is 1.6 times of the thickness of the side plate 13 of the breaking hammer.

[0057] Further, there are four through holes 23 at each end of the box body 21 , and there are two on the upper and lower sides of the positioning plate 22 , and the positioning plate 22 is located in the area surrounded by the four through holes 23 . That is, at the same end of the side wall of the box body 21 , two through holes 23 are arranged...

Abstract

The invention discloses a crushing hammer side plate welding assembly method, and belongs to the field of crushing hammers. The machining process comprises the following steps: firstly, blanks are tailored, and side plates are bent by using a pressing mechanism; then, the side plates are welded, and are leveled and corrected by using the pressing mechanism after welding; a welding fixing mechanismcan be used for welding; the machined side plates are put in a gap between a box and a baffle plate of the welding fixing mechanism, and are fixed by using positioning shaft rods; the distance between the two side plates is adjusted; fixing rods are used for welding and positioning to connect the two side plates; lining plates and top cover plates can be welded after fixation; shaft rods are taken down after welding, and are lifted out of an outer shell; and the top cover plates and the lining plates are welded from the inner side to finish the welding assembly. The method can guarantee the flatness before assembly, fully uses self structural characteristics of the side plates for positioned welding, reduces the deformation, and improves the product quality.

Description

technical field [0001] The invention relates to the technical field of breaking hammers, in particular to a welding and assembling method for a side plate of a breaking hammer. Background technique [0002] The hydraulic hammer has become an important working tool of the hydraulic excavator. The hydraulic hammer is powered by hydrostatic pressure to drive the piston to reciprocate. When the piston strokes, it hits the drill rod at high speed, and the drill rod breaks solids such as ore and concrete. The outer casing of the hydraulic hammer is an important component of the hydraulic hammer. The welding quality of the outer casing of the hydraulic hammer will directly affect the service life and working effect of the hydraulic hammer. Although the existing welding equipment can use robots to weld the wear-resistant plate, clamping plate and main hole rib on the side plate, the positioning welding effect on the side plate of the hydraulic hammer is poor during the overall weldi...
