Abstract

The invention discloses a simple elastic collet chuck which solves the problem in the existing collet chucks of being complex in structure. The collet chuck comprises a cylinder and a collet chuck body. An expanding sleeve is arranged at one end of the cylinder, the inner wall of the expanding sleeve is conical, the collet chuck body is attached to the inner wall of the expanding sleeve, sliding grooves are formed in the inner wall of the expanding sleeve and the outer wall of the collet chuck body, guiding pins are arranged in the two sliding grooves, the end portion of the collet chuck body is connected with one end of a cylinder piston, the other end of the cylinder piston rod is connected with a collet chuck pull rod, and a clamping adjusting nut is arranged on the collet chuck pull rod. The simple elastic collet chuck is simple in structure and convenient to operate.

Description

Simple elastic collet chuck
Technical field
The present invention relates to Machining Technology, be specifically related to a kind of Simple elastic collet chuck.
Background technology
collet chuck be by the tool holder of minor diameter in the device of spindle end, be mainly used in automatic lathe.Existing collet chuck general structure is complicated, cannot realize Quick-clamped and unclamp action, and inefficiency, especially in small batch workpiece processing and inapplicable.
Summary of the invention
The invention provides a kind of Simple elastic collet chuck, the baroque problem existing to solve existing collet chuck.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
Simple elastic collet chuck, comprise cylinder and collet chuck, one end at described cylinder is provided with expansion sleeve, the inwall of described expansion sleeve is taper, and described collet chuck laminating is arranged on the inwall of described expansion sleeve, on the inwall of expansion sleeve and the outer wall of collet chuck, is equipped with chute, in two chutes, be provided with pilot pin, the end of described collet chuck is connected with described cylinder piston rod one end, and the cylinder piston rod other end is connected with a collet chuck pull bar, on described collet chuck pull bar, is provided with clamping adjusting nut.
Beneficial effect of the present invention: when cylinder piston rod is during away from expansion sleeve one end motion, because the inwall of expansion sleeve is taper, and collet chuck laminating is arranged on the inwall of expansion sleeve, therefore in this process, collet chuck is by contraction clip clamping tool, and cylinder counter motion is back off tool.Clamping force is regulated by the clamping adjusting nut being arranged on collet chuck pull bar.Pilot pin in two chutes can effectively prevent that cylinder piston rod from driving collet chuck to rotate and affecting the clamping effect of collet chuck in when motion.The present invention is simple in structure, easy to operate.
Accompanying drawing explanation
Fig. 1 is the structural representation of Simple elastic collet chuck embodiment of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Simple elastic collet chuck as shown in Figure 1, comprise cylinder 1, collet chuck 2, expansion sleeve 3, cylinder piston rod 4, collet chuck pull bar 5, clamp adjusting nut 6, back-moving spring 7 and workpiece 8, one end at described cylinder arranges expansion sleeve, the inwall of described expansion sleeve is taper, described collet chuck laminating is arranged on the inwall of described expansion sleeve, on the inwall of expansion sleeve and the outer wall of collet chuck, be equipped with chute, in two chutes, be provided with pilot pin, the end of described collet chuck is connected with described cylinder piston rod one end, the cylinder piston rod other end is connected with a collet chuck pull bar, on described collet chuck pull bar, clamping adjusting nut is set, between clamping adjusting nut and cylinder piston, back-moving spring is set.
