Problems solved by technology

When turning, the axis of the small end is eccentric to the axis of the lathe, the cutting force is large, turning is difficult, the efficiency is low, and only the end face can be processed but not the inner hole.
Use soft claws to clamp the outer circle of the small end in the inner hole of the car, and reversely turn the inner hole of the small end with an inner hole cutter. It is difficult to measure the inner hole
Moreover, the clamping contact area is small, and the insufficient rigidity of the workpiece is easy to cause vibration and low production efficiency.

Embodiment Construction

[0011] The present invention is described below in conjunction with accompanying drawing.

[0012] attached figure 1 , 2 It is a kind of special fixture device described in the present invention, comprises chuck 2, and described chuck 2 is arranged on lathe main shaft 1, and described chuck 2 is provided with positioning collet 3; Described locating collet 3 is provided with There is a tapered positioning mandrel 6; a tapered sleeve 5 is set on the tapered positioning mandrel 6; the tapered sleeve 5 is arranged on the lathe spindle 1.

[0013] Due to the application of the above-mentioned technical solution, the present invention has the following advantages compared with the prior art:

[0014] A special fixture device of the present invention changes the original eccentric turning into coaxial turning, reduces the turning area and difficulty, and has high positioning accuracy, large turning force, easy clamping and dismounting of the workpiece, simple and fast operation, a...

Abstract

The invention discloses a special clamp device which comprises a chuck arranged on a lathe spindle. The special clamp device is characterized in that a positioning jacket is arranged in the chuck, a conical positioning mandrel is arranged in the positioning jacket, and a conical sleeve is sleeved on the conical positioning mandrel and arranged on the lathe spindle. Previous eccentric turning is changed into coaxial turning, so that turning area and difficulty are reduced; and the special clamp device is high in positioning accuracy, large in turning force, easy to realize clamping and demounting of workpieces and simple and quick in operation, and production efficiency is improved.

Description

technical field [0001] The invention relates to a clamp device, in particular to a clamp device used for turning a right-angled trapezoidal conical tube. Background technique [0002] At present, when turning the right-angled trapezoidal conical tube, when processing the large end face, the method of mandrel one clamping one top is used, which requires the axial clamping force of the end top seat. Due to the unevenness of the small end face of the part, it forms a point with the end face of the jaw. Contact, under the action of cutting force, it is easy to cause the workpiece to loosen and slip, so that the verticality between the side busbar and the large end surface is poor, and the turning large end is eccentric turning, and the length processing volume is large. The small end face of the turning is based on the large end face, and the outer surface of the eccentric cone of the workpiece is axially pressed with a nut. When turning, the axis of the small end is eccentric ...
