Description
Technical Field
The utility model discloses from the technique relates to a collet chuck device suitable for input shaft rough machining belongs to input shaft part rough machining equipment technical field.
Background
The steering gear is an important part of the automobile, and the accuracy of the steering gear structure directly influences the working performance of the steering gear. The input shaft part is used for assembling an automobile steering gear, the blank is round steel, and the rough machining process is performed after the round steel is subjected to thermal refining; as the outer surface of the round steel has burr hard points, the burr bending deformation is inevitably caused after quenching and tempering heat treatment, and certain difficulty is increased for the rough machining process of the clamped round steel. In the prior art, a three-jaw chuck is generally adopted for clamping round steel, if a jaw just touches a burr hard point on the round steel, the clamping is not firm, and if the jaw touches a part with bending deformation, the clamping is deviated, so that the subsequent process cannot be carried out; in addition, in order to avoid the problems, only manual clamping is adopted, but the labor intensity of workers is increased, and the production efficiency is reduced.
Disclosure of Invention
An object of the utility model is to the not enough of above-mentioned prior art, provide one kind and ensure the reliability of centre gripping through collet chuck, reduce staff's intensity of labour, clamping labour saving and time saving improves production efficiency greatly, the swift convenient collet chuck device who is applicable to input shaft rough machining of operation.
The utility model discloses a realize above-mentioned purpose through following technical scheme:
the utility model provides a collet chuck device suitable for input shaft rough machining, it comprises collet chuck, chuck seat, dial, main shaft, pull rod, hydro-cylinder seat, gyration hydro-cylinder and hydro-cylinder support, its characterized in that: the spindle is provided with a pull rod, one end of the pull rod is provided with a pull disc, the right side of the pull disc is provided with a chuck seat, a spring chuck is arranged in the chuck seat, and the spring chuck is fixedly connected with the spindle; an inner hole with the same diameter as the workpiece is formed in the center of the spring chuck, and a tooth groove is formed in the inner wall of the inner hole along the axial direction; elastic grooves which are divided into four equal parts are uniformly distributed in the radial direction of the inner hole; the other end of the pull rod is provided with an oil cylinder seat which is fixedly arranged on the bed body through an oil cylinder bracket, and the rear end of the oil cylinder seat is provided with a rotary oil cylinder.
Compared with the prior art, the utility model beneficial effect lie in:
the spring chuck device suitable for the rough machining of the input shaft clamps the input shaft by adopting the spring chuck, can automatically adjust centering and ensures the clamping reliability; the automatic assembling machine is quick and convenient to operate, simple in structure, high in adaptability, time-saving and labor-saving, reduces labor intensity of operators, greatly improves production efficiency, improves installation accuracy and guarantees machining quality. The problems that manual clamping is adopted in a traditional clamping method, labor intensity of workers is low, time and labor are wasted, and production efficiency is reduced are solved.
