Abstract

The invention provides a clamp for turning a thin-wall conical part, and relates to a clamp for turning a part. With the adoption of the clamp provided by the invention, the problems that assisting time is multiple, production efficiency is low, deformation is easy to generate, and a requirement of scale production cannot be met can be solved. The clamp is characterized in that the clamping face of a first clamp body is consistent to the outer conical face of the thin-wall conical part; the clamping face of a second clamp body is consistent to the inner conical face of the thin-wall conical part; a positioning shaft is tightly screwed on the second clamp body; the first clamp body and the second clamp body are arranged in parallel; one end of a core shaft is tightly screwed in a first center hole, and the other end of the core shaft is tightly screwed in a second center hole; a to-be-machined assembly which is formed by overlapping a plurality of thin-wall conical parts is sleeved on the core shaft between the first clamp body and the second clamp body; the clamping face of the first clamp body is tightly adhered to the outer conical face of the thin-wall conical part; and the clamping face of the second clamp body is tightly adhered to the inner conical face of the thin-wall conical part. The clamp provided by the invention is used for the process of turning the thin-wall conical part.

Description

Thin-walled conical part turning anchor clamps

Technical field

The present invention relates to a kind of part turning anchor clamps, belong to the Machining Technology field.

Background technology

Thin-walled conical part (as shown in Figure 1) turning operation is in implementation process, if single-piece work, the process of clamping is more frequent; Non-cutting times such as tool setting, measurement, adjustment are many, and production efficiency is low, satisfied not batch production requirement; And because this thin-walled conical part wall thickness has only 5mm; Very easily produce distortion during clamping, size changes after unloading clip appears in regular meeting, causes size to exceed the problem of deviation.

Summary of the invention

The objective of the invention is for solve the non-cutting time that exists in the thin-walled conical part turning operation many, production efficiency is low, yielding and can't satisfy the problem of batch production requirements, and then a kind of thin-walled conical part turning anchor clamps are provided.

Technical scheme of the present invention is: thin-walled conical part turning anchor clamps comprise first clamp body, second clamp body, mandrel and locating shaft; The male cone (strobilus masculinus) of the clamping area of said first clamp body and thin-walled conical part is consistent; The inner conical surface of the clamping area of second clamp body and thin-walled conical part is consistent, has first centre bore on said first clamp body, has second centre bore on second clamp body; Said locating shaft is tightened on second clamp body; Said first clamp body and second clamp body are set up in parallel, and an end of mandrel is tightened in first centre bore, and the other end of mandrel is tightened in second centre bore; The axis of the axis of said first clamp body, the axis of mandrel, second clamp body and the axis of locating shaft are on same straight line; A plurality of thin-walled conical parts are stacked together and constitute assembly to be processed, and assembly to be processed is sleeved on the mandrel, and assembly to be processed is between first clamp body and second clamp body; The male cone (strobilus masculinus) of the clamping area of first clamp body and thin-walled conical part is close to, and the inner conical surface of the clamping area of second clamp body and thin-walled conical part is close to.

The present invention compared with prior art has following effect: a plurality of thin-walled conical parts of clamping of anchor clamps of the present invention, satisfied batch production requirement; Anchor clamps carry out conformal to the thin-walled conical part simultaneously, have guaranteed that better product quality, production efficiency have improved 12 times, have alleviated working strength of workers.In addition, the present invention also have simple in structure be convenient to the advantage of clamping.

Description of drawings

Fig. 1 is the structural representation of thin-walled conical part, and Fig. 2 is an overall structure sketch map of the present invention.

The specific embodiment

The specific embodiment one: combine Fig. 1 and Fig. 2 that this embodiment is described; The thin-walled conical part turning anchor clamps of this embodiment comprise first clamp body 1, second clamp body 2, mandrel 3 and locating shaft 4; The male cone (strobilus masculinus) 5-1 of the clamping area of said first clamp body 1 and thin-walled conical part 5 is consistent; The inner conical surface 5-2 of the clamping area of second clamp body 2 and thin-walled conical part 5 is consistent, has the first centre bore 1-1 on said first clamp body 1, has the second centre bore 2-1 on second clamp body 2; Said locating shaft 4 is tightened on second clamp body 2; Said first clamp body 1 and second clamp body 2 are set up in parallel, and an end of mandrel 3 is tightened in the first centre bore 1-1, and the other end of mandrel 3 is tightened in the second centre bore 2-1; The axis of the axis of the axis of the axis of said first clamp body 1, mandrel 3, second clamp body 2 and locating shaft 4 is on same straight line; A plurality of thin-walled conical parts 5 are stacked together and constitute assembly to be processed, and assembly to be processed is sleeved on the mandrel 3, and assembly to be processed is between first clamp body 1 and second clamp body 2; The male cone (strobilus masculinus) 5-1 of the clamping area of first clamp body 1 and thin-walled conical part 5 is close to, and the inner conical surface 5-2 of the clamping area of second clamp body and thin-walled conical part 5 is close to.

This embodiment utilizes male cone (strobilus masculinus) 5-1, inner conical surface 5-2 and the part centre bore 5-3 of thin-walled conical part to realize the location; At first with locating shaft 4 be clamped in use (locating shaft 4 after installing and fixing unloads after remaining to batch completion always) in the lathe chuck jaw; Beat the table centering, circle is beated and is not more than 0.01; Then second clamp body 2 is screwed with locating shaft 4; One end of mandrel 3 is tightened in the second centre bore 2-1 of second clamp body 2; To become assembly to be processed to be sleeved on the mandrel 3, automatic capturing between each thin-walled conical part 5, restraint of liberty degree; A plurality of thin-walled conical parts 5 are cut to the enterprising driving of lathe with the anchor clamps clamping, said lathe model is CA6140 again.

The specific embodiment two: combine Fig. 1 that this embodiment is described, first clamp body 1 of this embodiment is steel first clamp body, and second clamp body 2 is steel second clamp body.Other composition is identical with the specific embodiment one with annexation.
