Abstract
The utility model relates to a fixture for turning on lathes, in particular to a fixture for turning of large-diameter thin-walled parts. The fixture comprises a circular body. The front end face of the body is provided with a circular workpiece holding cavity. The body is divided into a plurality of mutually isolated sector parts by a plurality of radial cut slots. The rear end face of each sector part is provided with connecting holes to be connected with one jaw of a machine chuck. The fixture has the advantages that before turning a thin-walled hollow tube, the parts of the body are fitted to the jaws of the machine chuck respectively, the workpiece is tightly held with the inner periphery of the circular workpiece holding cavity, and the parts of the workpiece evenly bear clamping force; accordingly, deformation of the large-diameter thin-walled workpiece is reduced, and machining quality of the workpiece is improved.
Description
Technical field
The utility model relates to a kind of lathe workpiece machining clamp, particularly a kind of workpiece machining clamp of large diameter thin wall part.
Background technology
During existing machined is produced, often to process the thin-wall hollow pipe that diameter is larger, and while adopting scroll chuck on conventional lathe or chuck to clamp, because its diameter is large, wall thickness is thinner, and the point of application of the chucking power of chuck is inhomogeneous, thereby easily producing clamping deformation, this has reduced the crudy of workpiece.Therefore, need a kind of device to reduce the distortion of workpiece when being clamped by chuck, improve crudy.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of distortion can reduce the large diameter thin wall part and clamped by chuck the time is provided, and improves the workpiece machining clamp of the large diameter thin wall part of Vehicle Processing quality.
The technical solution of the utility model is:
A kind of workpiece machining clamp of large diameter thin wall part, comprise and the body of a ring-type have annular workpiece placing chamber on the body front end face; By several, the groove that cuts off radially is divided into a plurality of fan-shaped part be separated from each other to body, on the rear end face of each fan-shaped part, be provided with can with a connecting hole that claw is connected of machine chuck.
The described groove that cuts off can arrange three, and it is divided into three fan-shaped parts to body, can be used in conjunction with scroll chuck.
The described groove that cuts off also can arrange four, and it is divided into four fan-shaped parts to body, can be used in conjunction with chuck.
The utility model has the advantages that: when the car thin-wall hollow pipe, the various piece of body of the present utility model is assembled together with each claw of lathe chuck respectively, utilize the inner periphery clamping work pieces of annular workpieces placing chamber, the clamping force of workpiece each several part is uniformly distributed, thereby reduced the distortion of large diameter thin wall workpiece, improved the crudy of workpiece.
The accompanying drawing explanation
Fig. 1 is front end face structural representation of the present utility model;
Fig. 2 is rear end face structural representation of the present utility model;
Fig. 3 be the utility model while being connected with claw side sectional structure schematic diagram.
The specific embodiment
As shown in the figure, the utility model comprises the body 1 of a ring-type, has annular workpiece placing chamber 2 on the body front end face; By several, the groove 3 that cuts off radially is divided into a plurality of fan-shaped part be separated from each other to body, is provided with the connecting hole 4 that can be connected with a claw 5 of machine chuck on the rear end face of each fan-shaped part.
When the utility model embodiment and scroll chuck are used in conjunction with, the described groove 3 that cuts off can arrange three (as shown in the figure), and it is divided into three fan-shaped parts to body, three claws of corresponding chuck.
When the utility model embodiment and chuck are used in conjunction with, the described groove 3 that cuts off can arrange four, and it is divided into four fan-shaped parts to body, four claws of corresponding chuck.
