Description
Technical field
The invention belongs to excavator field, be specifically related to universal jointing device for crawler frame on small-type excavators.
background technologythe welding of crawler type crawler of excavator shelf structure part, assembly welding form, and in actual production process, all can be produced certain distortion after welding by welding tool, and there is certain residual stress in inside.Welding stress and distortion directly affects the shape and size of welding, when being out of shape serious, even can produce local laceration phenomenon; In addition, distortion also causes certain difficulty to integrally-built processing, and needs to increase cost that is correcting deformed and machining, in common welding tooling design, often design frock respectively by left and right, these frocks not only occupy large quantity space, manufacture and safeguard also very loaded down with trivial details.
summary of the invention
In order to solve prior art Problems existing, the invention provides universal jointing device for crawler frame on small-type excavators.There is structure simple, the not easily feature of eccentric wear.
Object of the present invention carrys out specific implementation by the following technical programs:
Universal jointing device for crawler frame on small-type excavators, comprise square chest 1, fastener shaft 2, clamp nut 3, fastening cover plate 4, height adjustment seat 5, to heart supporting seat 1, to heart supporting seat 27, square chest 1 symmetrically structure, square chest side is fixed with fastener shaft by clamp nut, fastening cover plate is provided with between clamp nut and fastener shaft, square chest adjacent fastener axle place is provided with height adjustment seat, and height adjustment seat side is provided with to heart supporting seat one with to heart supporting seat two.
Further, it is two to heart supporting seat one quantity.
Further, HRC50-55 is to heart supporting seat one with to the quenching hardness of heart supporting seat two.
Compared with prior art, the present invention has following beneficial effect:
Welding tooling of the present invention, convenient to use, reduce frock manufacturing cost, be convenient to frock maintenance and management, and well solve driving wheel and rail chain eccentric wear problem.
