Embodiment Construction

[0026] The following is attached Figure 1-Figure 9 The features and principles of the present invention are described in detail, and the examples given are only used to explain the present invention, not to limit the protection scope of the present invention.

[0027] Such as figure 1 As shown, the invention includes a base 1, two side plates 2, a cover plate 3, two positioning blocks 4, a floating pressing mechanism 5, a positioning pin 8 and a radial pressing mechanism 6. The bottoms of the two side plates 2 are fixedly welded on the base 1; the cover plate 1 is fixedly connected to the top of the two side plates 2 by screws, and the two side plates and the cover plate form a "door" shape. A floating compression cylinder 53 is installed in the "gate" structure, which makes full use of the space of the structure and has a compact structure. Moreover, the cover plate 1 and the side plate 2 also play a protective role, preventing the iron filings and other sundries generated...

Abstract

The invention discloses a full automatic tooling clamp for semi-crankshaft finish machining. The tooling clamp is characterized by comprising a base, two side plates, a cover plate, two locating blocks, a floating pressing mechanism, a locating pin and a radial pressing mechanism, wherein the bottom parts of the two side plates are fixedly welded on the base, the cover plate is fixedly connected with the top parts of the two side plates through screws, and an n shape is formed by the two side blocks and the cover plate; the top of the cover plate is transversely and fixedly provided with the two locking blocks, the top surfaces of the two locking blocks are located in a same horizontal plane, a locating pin mounting hole and a crankshaft journal mounting hole which vertically penetrate through the cover plate are formed between the two locating blocks of the cover plate and the locating pin is arranged in the locating pin mounting hole; the cover plate is longitudinally provided with the radial pressing mechanism, and the floating pressing mechanism is arranged above the locating block. The full automatic unmanned processing can be realized; furthermore, each link can be detected, including the feeding and discharging in-place detection of a manipulator, work-piece clamping and loosening detection, work-piece clamping in-place request processing or discharging detection and the like.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to the finishing process of the front and rear semi-crankshaft full-automatic production lines, and cooperates with a manipulator to complete the full-automatic machining of the end face milling of the crankshaft pin hole and the fine boring process of the pin hole. Background technique [0002] The labor cost in our country is increasing year by year. At the same time, due to the development of science and technology and the improvement of automation technology, the cost of automation is getting lower and lower than that of labor. [0003] Now the processing of the front and rear half crankshafts mainly includes loading and unloading of the machine tool, positioning of the workpiece, and workpiece clamping, and these processes are all used in the existing half crankshaft machining process due to the particularity of the half crankshaft structure. Completed manually or...
