Abstract
The utility model relates to a thin-wall workpiece processing tool which is characterized by comprising a mandril. The mandril is mainly composed of a flange connecting disc and a center sleeve. A center hole is formed in the center sleeve. A thread installation hole is formed in the center hole. A center screw rod is arranged in the thread installation hole in a matched mode. A press cover is sleeved on the center screw rod. The diameter of an outer circle of the center sleeve is identical to the inner diameter of a to-be-processed workpiece. The to-be-processed workpiece is sleeved on the center sleeve and connected with the flange connecting disc through a screw rod. In practical processing, the mandril is firstly clamped on a clamp disc of a machine tool and tool alignment and location are completed simultaneously so that the aims of one-time alignment of the thin-wall workpiece and repeated processing can be achieved. After the location of the tool, the to-be-processed workpiece is clamped and installed on the tool through the center screw rod and the screw rod so that clamping and installation of the tool is completed rapidly and outer circle cutting processing can be conducted after the clamping and the installation. The thin-wall workpiece processing tool has the advantages of being high in a finish product rate, small in labor intensity, high in work efficiency, capable of reducing production cost to a large degree and the like.
Description
Technical field
The utility model belongs to the machining technique field, particularly relates to a kind of thin wall work-piece processing tool.
Background technology
For the higher thin wall work-piece of cylindrical required precision, the general traditional handicraft that adopts is processed during machining on lathe, be first roughing, again fine finishining, and the adapted dial gauge carries out centering simultaneously, and workpiece of every processing needs again centering once to waste time and energy, and precision is not easy to be guaranteed.In addition, because the cutting face is thinner, stress surface is deformed, affect workpiece fineness, justify the required precision such as beat, cause product percent of pass lower.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, improve working (machining) efficiency, improve the thin wall work-piece processing tool of processing precision of products.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of thin wall work-piece processing tool, it is characterized in that: described this frock comprises mandrel, described mandrel mainly is made of flange terminal pad and center, be provided with centre bore in the described center, be provided with threaded mounting hole in the described centre bore, be fitted with center bolt in the described threaded mounting hole, be set with gland on the described center bolt; The outside diameter of described center is identical with the workpiece to be machined internal diameter, and described work piece is sleeved on the center, and by screw rod adpting flange terminal pad.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, namely adopt the axial grip mode to suppress workpiece to be machined in the distortion that adds the radial stress in man-hour.At first mandrel is clamped on the machine chuck man-hour in actual adding, complete frock centering of while and location, thereby realized the purpose that centering of thin wall work-piece repeats to process, after tool locating is finished, processed workpiece is installed on the frock, and by center bolt and gland with Work-sheet pressing, to prevent workpiece rotating, the ring flange of workpiece is fixed by screw rod and frock flange terminal pad, so just workpiece to be machined and mandrel can be fastened as a whole, finish the rapid-mounted of workpiece, be installed and realize external cutting processing after finishing.This kind processing mode has yield rate and improves in sum, and labour intensity is little, the advantages such as operating efficiency height, but also decrease production cost.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the workpiece to be machined structural representation.
Among the figure: 1, mandrel; 1-1, flange terminal pad; 1-2, center; 1-3, centre bore; 1-4, threaded mounting hole; 2, center bolt; 3, gland; 4, screw rod; 5, workpiece to be machined.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1 and Fig. 2, a kind of thin wall work-piece processing tool, described this frock comprises mandrel 1, described mandrel mainly is made of flange terminal pad 1-1 and center 1-2, be provided with centre bore 1-3 in the described center, be provided with threaded mounting hole 1-4 in the described centre bore, be fitted with center bolt 2 in the described threaded mounting hole 1-4, be set with gland 3 on the described center bolt 2; The outside diameter of described center 1-2 is identical with workpiece to be machined 5 internal diameters, and described work piece is sleeved on the center 1-2, and by screw rod 4 adpting flange terminal pad 1-1.
This frock using method, at first mandrel is clamped on the machine chuck man-hour in actual adding, complete frock centering of while and location, thereby realized the purpose that centering of thin wall work-piece repeats to process, after tool locating is finished, processed workpiece is installed on the frock, and by center bolt and gland with Work-sheet pressing, to prevent workpiece rotating, the ring flange of workpiece is fixed by screw rod and frock flange terminal pad, so just workpiece to be machined and mandrel can be fastened as a whole, finish the rapid-mounted of workpiece.
This kind processing mode has yield rate and improves in sum, and labour intensity is little, the advantages such as operating efficiency height, but also decrease production cost.
Although the above is described preferred embodiment of the present utility model by reference to the accompanying drawings; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away from the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the present utility model.
