Abstract

The utility model discloses a turning clamp for a conical thin-wall part, which relates to a turning clamp for a part and aims at solving the problems of long auxiliary time, low production efficiency, easy deformation and incapability of meeting batch production requirements in the turning work procedure of the conical thin-wall part. The clamping surface of a first clamp body is coincident with the outer conical surface of a thin-wall conical part, the clamping surface of a second clamp body is coincident with the inner conical surface of the conical thin-wall part, a positioning shaft is tightly screwed on the second clamp body, the first clamp body and the second clamp body are in parallel arrangement, one end of a mandrel is tightly screwed in a first center hole, the other end of the mandrel is tightly screwed in a second center hole, an assembly to be processed, formed by overlapping a plurality of conical thin-wall parts, is sheathed on the mandrel arranged between the first clamp body and the second clamp body, the clamping surface of the first clamp body is tightly pasted with the outer conical surface of the thin-wall conical part, and the clamping surface of the second clamp body is tightly pasted with the inner conical surface of the conical thin-wall part. The turning clamp for the conical thin-wall part is used in the turning work procedure of the conical thin-wall part.

Description

Thin-walled conical part turning anchor clamps

Technical field

The utility model relates to a kind of part turning anchor clamps, belongs 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, does not satisfy 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.

The utility model content

The purpose of this utility model be 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 provide a kind of thin-walled conical part turning anchor clamps.

The technical solution of the utility model is: thin-walled conical part turning anchor clamps comprise first clamp body, second clamp body, mandrel and locating shaft, the clamping area of described first clamp body is consistent with the male cone (strobilus masculinus) of thin-walled conical part, the clamping area of second clamp body is consistent with the inner conical surface of thin-walled conical part, have first centre bore on described first clamp body, have second centre bore on second clamp body, described locating shaft is tightened on second clamp body, described first clamp body and second clamp body are set up in parallel, one end of mandrel is tightened in first centre bore, the other end of mandrel is tightened in second centre bore, the axis of described first clamp body, the axis of mandrel, the axis of 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, 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 utility model compared with prior art has following effect: a plurality of thin-walled conical parts of clamping of anchor clamps of the present utility model, 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 utility model also has simple in structure and is 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 schematic diagram of the present utility model.

The specific embodiment

The specific embodiment one: present embodiment is described in conjunction with Fig. 1 and Fig. 2, the thin-walled conical part turning anchor clamps of present embodiment comprise first clamp body 1, second clamp body 2, mandrel 3 and locating shaft 4, the clamping area of described first clamp body 1 is consistent with the male cone (strobilus masculinus) 5-1 of thin-walled conical part 5, the clamping area of second clamp body 2 is consistent with the inner conical surface 5-2 of thin-walled conical part 5, have the first centre bore 1-1 on described first clamp body 1, have the second centre bore 2-1 on second clamp body 2, described locating shaft 4 is tightened on second clamp body 2, described first clamp body 1 and second clamp body 2 are set up in parallel, one end of mandrel 3 is tightened in the first centre bore 1-1, the other end of mandrel 3 is tightened in the second centre bore 2-1, the axis of described first clamp body 1, the axis of mandrel 3, the axis of the axis of 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, 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.

Present embodiment utilizes male cone (strobilus masculinus) 5-1, the inner conical surface 5-2 of thin-walled conical part and part centre bore 5-3 to realize the location, at first locating shaft 4 is clamped in use in the lathe chuck jaw (locating shaft 4 after installing and fixing unloads after remaining to always and batch finishing), 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, the restraint of liberty degree, again a plurality of thin-walled conical parts 5 are carried out turning with the anchor clamps clamping to lathe, described lathe model is CA6140.
