Improved assembly structure of chuck jaw drive column

The assembly structure of the clip chuck driving column of the present invention is improved, and is a structurally improved design for improving the assembly of the jaws and the pulling column when the chuck is rotated.

Generally, the hydraulic chuck structure for machining the workpiece is generally matched with the oil pressure pipeline, and the valve plate component assembled in the hollow hollow hydraulic chamber is controlled, and the column is locked by the valve plate member, so that the control jaw block is made. The tension is shifted to achieve the operation of clamping the workpiece by the chuck, wherein the locking structure design of the pull column and the valve plate member of the relevant jaw is substantially set as shown in the fifth and sixth figures, that is, sliding The moving valve plate member (30) has the same number of clamping jaws on the circular plate surface, and the column hole (31) for the pull column (40) is locked in the recessed class slot edge. The backing ring (32) and the locking screw ring member (33) are configured to lock the pull rod (40) at one end of the screw head (41), and then lock and assemble, and to prevent the pull column (40) from locking the group, When the rotation is controlled, the slot (43) for the insertion of the fixed tip (42) is set on the locking end face of the pull column (40), and the pull column (40) is inserted into the valve during assembly. After the one end of the plate member (30) is attached, the fixing tip (42) is inserted and positioned in the opposite hole of the valve plate according to the preset slot (43), and is oriented and locked, which is convenient for the valve plate member (30). ) The other side plate is fixedly combined with the anti-leakage ring (32) and the spiral ring member (33) to achieve the fixed assembly of the pull column (40), and the inclined convex rail (44) and the clip through the pull column (40) The relative inclination of the side of the claw bottom slider is inserted into the insertion groove, and the valve plate member (30) is hydraulically controlled to slide, so that the pull column (40) is outwardly extended and displaced according to the convex rail ( 44) The tilting guide jaws are locked to the slider, and then moved inwardly to achieve the opposite outward displacement operation of the control jaw; when it is displaced inward with the valve plate member (30), the convex rail is compliant ( 44) The inclined direction naturally encloses the slider in the inwardly-clamped shape, and the belt is formed to form a contraction displacement of the jaws, thus achieving the clamping operation control of the entire chuck; and the entire pull column (40) Mainly according to the locking end, it is directly placed in the slot of the class hole (31), and the corresponding locking hole is matched with the locking group of the locking screw ring member (33); it is usually required to facilitate the locking group and prevent looseness. The positioning of the insertion of the fixed tip (42) on one side is determined. However, since the surface actually worn is small, the diameter of the fixed tip (42) which is based on the slot is usually extremely thin, forming the actual locking support strength. Insufficient, very easy to break As a result, the tension of the pull column (40) is unstable, and only the pull column (40) is locked, so as to ensure the clamping and the safety of the entire jaw, so the locking structure of the pull column (40) is actually It has always been the industry's active pursuit of improvement. How to develop a set of easy-to-lock locks and to achieve the anti-rotation of the pull-tab (40) locking structure, in fact, has been actively researched and improved by the industry and users. .

In view of the above-mentioned hydraulic chuck structure, the creator is extremely aware of the fact that the jaw member is prone to looseness and the use of the clamp is not correct. Over the years, in the research and development experience of the chuck structure, after careful research and improvement of the design, the development of the assembly structure of the collet jaw drive transmission column has been developed, and the pull column and the valve plate piece in the jaw linkage structure of the chuck are clamped. The locking step slot hole is set to have a side surface insertion and positioning structure, so that the assembly of the column is not turned to the lock, and then the locking operation is performed, so that the entire pull column can be safely controlled and operated. The stable assembly effect effectively overcomes the conventional clamping operation caused by the clamping and clamping pressure, and the use of the clamping instability is lacking.

The purpose of this creation is to lock the valve plate member into the concave stepped slot of the pull column, and set the concave step groove to a rectangular shape or a square shape, and insert the insertion end with the insertion end of the top end of the pull column. The safety orientation insert assembly of the pull column is achieved, and the anti-leak lock group positioning of the lock nut is ensured to ensure the fixing and safety of the pull column lock group, and the pull column moves up and down with the valve plate member, and the control clamp clamp is continuously controlled. The stable safety and reliability during the operation, further ensuring the safety and speed of the chuck structure processing and the pinch control, and the practical purpose of improving the processing quality of the chuck.
