Embodiment Construction

[0020] Below in conjunction with accompanying drawing and embodiment of description, specific embodiment of the present invention is described in further detail:

[0021] refer to Figure 1 to Figure 10 The automatic expansion and breaking of a crank connecting rod and its loading and unloading device include a table 1 and a feeding device 3 installed on the table 1, an expansion device 4, a discharging device 6, and a feeding device 3. It includes a first feeding device 3a, a second feeding device 3b and a third feeding device 3c. The outlet of the first feeding device 3a is provided with a processing table that can drive the crankshaft connecting rod to slide on the table 1 2. The outlets of the second feeding device 3b and the third feeding device 3c are equipped with an assembly device 5 for assembling the broken crank connecting rod, and the side of the processing table 2 is provided to drive the processing table 2 to move to the The first horizontal moving device 2a bel...

Abstract

The invention relates to the field of automobile part manufacture, in particular to an automatic expansion breaking, loading and unloading device for a crank connecting rod. A machining platform capable of driving the crank connecting rod to slide on a table is arranged at a discharge port of a first loading device, and an assembling device used for assembling the crank connecting rod obtained after expansion breaking is arranged at discharge ports of a second loading device and a third loading device; an expansion breaking device comprises a core rod and a vertical moving device used for driving the core rod to do vertical reciprocating motion; the assembling device comprises clamping blocks capable of clamping the two sides of the large-shaft end of the crank connecting rod obtained after expansion breaking and a limiting device used for limiting the crank connecting rod obtained after expansion breaking from moving; and third horizontal moving devices used for driving the clamping blocks to oppositely move and clamping the two sides of the large-shaft end of the crank connecting rod obtained after expansion breaking are arranged on the two sides of the limiting device. Accordingto the device, continuous expansion breaking machining and automatic loading and unloading can be conducted on the crank connecting rod, the cover ends and the rod ends of the same group of crank connecting rods can be assembled together after machining is completed, and the condition that parts are mixed is avoided.

Description

technical field [0001] The invention relates to the field of auto parts manufacturing, in particular to an automatic opening and breaking of a crank connecting rod and its loading and unloading device. Background technique [0002] The shape of the crank connecting rod is relatively complex, easy to deform, poor in rigidity, high in dimensional accuracy, positional accuracy and surface quality, and it is difficult to manufacture. The quality of the connecting rod manufacturing technology directly affects the performance and economic performance of the connecting rod, as well as the survival and development of an enterprise. With the development of production technology, the traditional manufacturing technology cannot meet the current production requirements gradually. Many connecting rod manufacturers in foreign countries have proposed the "expansion technology", and the application of the connecting rod technology has brought about significant changes in the processing qual...
