Abstract
The invention discloses a turning tool for machining an inner hole of a thin-wall part. The turning tool for machining the inner hole of the thin-wall part is characterized by comprising a connecting disk and a press plate, the axis of the connecting disk and the axis of a locating disk are arranged on the same straight line, the right portion of the connecting disk is fixedly connected with the left portion of the locating disk, and a locating spigot is formed in the right end of a center hole of the locating disk; and two to four air cylinders are arranged between the connecting disk and the locating disk in the circumferential direction, piston rods of the air cylinders are parallel to the axis of the locating disk, and cylinder bodies of the air cylinders are fixedly connected with the outer wall of the locating disk; the number of the press plate is one, a lathe tool receding hole is formed in the center of the press plate, and connecting screws are fixedly connected with the right ends of the piston rods of the corresponding air cylinders after penetrating through threaded installing holes formed in the press plate. According to the turning tool for machining the inner hole of the thin-wall part, due to the facts that locating is carried out on the outer circle surface of the thin-wall part, and the end face of the thin-wall part is tightly pressed through the air cylinders and the press plate, the side wall of the thin-wall part cannot bear radial force, deformation, in the radial direction, of the thin-wall part is avoided, and then the roundness of the inner hole of the thin-wall part is ensured.
Description
Technical field
The invention belongs to frock clamp field, specifically, relate in particular to a kind of automobile-used frock for processing thin-walled endoporus.
Background technology
In mechanical engineering field, thin-wall part (being the workpiece G in Fig. 1) is a kind of utilization parts widely, and the endoporus of thin-wall part usually needs to carry out turning processing.At present, generally by conventional scroll chuck, clamp the periphery of thin-wall part, then use the endoporus of processing thin-walled of lathe tool.
The defect of existing processing mode is: due to the thinner thickness of thin-wall part, easily produce distortion, thereby make the circularity of thin-wall part endoporus be difficult to be guaranteed after scroll chuck clamping, be badly in need of solving above-mentioned technical barrier for this reason.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of automobile-used frock for processing thin-walled endoporus, and wish guarantees the circularity of thin-wall part endoporus.
Technical scheme of the present invention is as follows: a kind of automobile-used frock for processing thin-walled endoporus, it is characterized in that: comprise terminal pad (1) and pressing plate (4), wherein the axial line of terminal pad (1) and positioning disk (2) is on same straight line, the right part of this terminal pad and positioning disk (2) left part is fixed, and the right-hand member of positioning disk (2) centre bore is provided with positioning spigot; Between described terminal pad (1) and positioning disk (2) along being circumferentially with 2-4 cylinder (3), the axis parallel of the piston rod of this cylinder and positioning disk (2), and the cylinder body of cylinder (3) and positioning disk (2) outer wall are fixed; The number of described pressing plate (4) is one, and the center of this pressing plate has a lathe tool resigning hole (4a), and attachment screw (5) passes after the threaded mounting hole (4b) on this pressing plate, fixes respectively with the piston rod right-hand member of corresponding described cylinder (3).
During clamping workpiece (G), first workpiece (G) is positioned to the positioning spigot place of described terminal pad (2) centre bore right-hand member, then loads onto described pressing plate (4), next starts described cylinder (3), and pressing plate (4) is compressed workpiece (G), so that the endoporus of lathe tool turner (G).
Adopt above technical scheme, the present invention positions the periphery of thin-wall part, and by cylinder and pressing plate, the end face of thin-wall part is compressed, so just make the sidewall of thin-wall part not bear power radially, thereby prevent that thin-wall part from producing distortion diametrically, and then the circularity of assurance thin-wall part endoporus, so just overcome well the defect of traditional processing mode, and this automobile clamper is simple in structure, easy to implement, easy to operate, be specially adapted to the endoporus of processing thin-walled.
As optimal design, the number of described cylinder (3) is three, these cylinders (3) being circumferentially evenly arranged along described positioning disk (2).
Adopt above structure, the number of described cylinder (3) is moderate, and not only thrust is reliable, even, and because selecting too much cylinder (3), does not increase the cost of this fixture.
In this case, described threaded mounting hole (4b) be shaped as " 8 " font, the aperture of one of them hole section is greater than the aperture of another hole section, the diameter of described attachment screw (5) head is between the aperture of two hole sections of threaded mounting hole (4b).
Adopt above structure, we just can carry out pressing plate (4) described in dismounting by attachment screw (5) is mobile between two hole sections of threaded mounting hole (4b), convenient to operation, laborsaving.
As preferably, the circumferential uniform bolt through-hole (1a) that has in edge on the round plate on described terminal pad (1) left side, the axis parallel of the axial line of this bolt through-hole and terminal pad (1), the bolt facilitating like this by being located in bolt through-hole (1a) is fixedly connected with the ring flange of lathe.
Beneficial effect: the present invention positions the periphery of thin-wall part, and by cylinder and pressing plate, the end face of thin-wall part is compressed, so just make the sidewall of thin-wall part not bear power radially, thereby prevent that thin-wall part from producing distortion diametrically, and then guarantee the circularity of thin-wall part endoporus, so just overcome well the defect of traditional processing mode, and this automobile clamper is simple in structure, easy to implement, easy to operate, be specially adapted to the endoporus of processing thin-walled.
