Embodiment Construction
[0011] The two-way eccentric crankshaft ( figure 1 Middle 1) placed on the center hole processing guide plate ( figure 1 Middle 3) in the middle, through the connecting rod ( figure 1 Middle 2), flat pad ( figure 1 Middle 4), spring washer ( figure 1 5) and nut ( figure 1 Middle 6) connect into a whole, fix this whole on the drilling machine, and the drill bit processes the guide plate through the center hole ( figure 1 Middle 3) It can quickly and accurately locate, drill and process three center holes, and use the double top to pass the center hole to move the two-way eccentric crankshaft ( figure 1 Middle 1) The top is clamped on the ordinary lathe to complete the turning process of the two-way eccentric crankshaft.

A bi-directional eccentric crankshaft center hole processing clamp is mainly composed of a center hole processing guide plate, a connecting rod, a flat cushion, an elastic cushion and a nut and the like. A bi-directional eccentric crankshaft is placed between two center hole processing guide plates to be connected to be an integrated body by utilizing the connecting rod, the flat cushion, the elastic cushion and the nut, the integrated body is clamped on a drilling machine, and three center holes are drilled in the end face of the crankshaft by rapid and accurate positioning through the center hole processing guide plates.
Description
technical field [0001] The technology of the invention relates to a bidirectional eccentric crankshaft processing fixture, which can conveniently, quickly and accurately process the center hole of the bidirectional eccentric crankshaft, and process the bidirectional eccentric crankshaft with double tops. Background technique [0002] With the development of modern technology, textile machinery has developed greatly. In textile machinery, there is a lifting system that uses a two-way eccentric crankshaft. For a two-way eccentric crankshaft, the symmetry of the two-way eccentric axis to the main shaft axis must be ensured. Generally, it is difficult to meet the processing accuracy, size and technical requirements for lathe processing. Of course, there are not only bidirectional eccentric crankshafts in textile machinery, but also many bidirectional eccentric crankshafts in other machinery. To this end, a series of technical researches have been carried out, and the center hol...
