Abstract

The utility model relates to a lathe machining fixture which comprises a base plate. A center hole, press block mounting holes and thread mounting holes respectively formed in the base plate, wherein the center hole is formed in the center of the base plate, the press block mounting holes are formed in the middle portion of the base plate and are circularly arranged around the center hole, and the thread mounting holes are formed in the end portion of the base plate and are circularly arranged around the center hole. The lathe machining fixture is suitable for various thin-walled parts, the press block mounting holes or the thread mounting holes are used for clamping a thin-walled part on the lathe machining fixture, the inner circle, the outer circle and the end face of the thin-walled part are machined, and thus the problem of workpiece deformation caused by the fact that the thin-walled part is directly clamped by a lathe claw is solved, machining precision of the parts is improved. Lightening holes in the base plate reduces the weight of the base plate, and thus the lathe machining fixture is convenient to operate and install. Compared with the traditional machining method, machining efficiency is improved, machining precision of a workpiece is guaranteed, and loss caused by workpiece deformation is reduced.

Description

The lathe clamp for machining
Technical field
The utility model belongs to the machine tooling field, is specifically related to a kind of lathe clamp for machining.
Background technology
development along with modern processing industry, reduce production costs, improving working (machining) efficiency must be following development trend, at present, the lathe processing parts, usually the way of taking is exactly to utilize the pawl dish that lathe carries to carry out clamping processing to part, but run into the part of thin wall, utilize the pawl dish directly part to be carried out clamping, due to the thin distortion that easily causes part of thin-walled material shape, it is large that mismachining tolerance becomes, can't guarantee required precision to the part that the depth of parallelism has higher requirements, the part that even processes does not reach Application standard, cause the waste on manpower and materials.
Summary of the invention
In view of this, the utility model provides a kind of lathe clamp for machining, and is simple in structure, and processing ease has solved the part deformation problem that causes in the thin wall process, has improved machining accuracy.
The utility model discloses a kind of lathe clamp for machining, comprise the chassis, have centre bore, briquetting installing hole and threaded mounting hole on described chassis, described centre bore is positioned at center chassis, described briquetting mounting hole site is in chassis middle part and around the centre bore annular array, and described threaded mounting hole is positioned at the end, chassis and around the centre bore annular array.
Further, the one side on described chassis is provided with the circular groove concentric with centre bore.
Further, have lightening hole on described chassis.
beneficial effect of the present invention is: machine processing clamp of the present utility model, be applicable to process the part of all kinds of thin walls, can utilize briquetting installing hole or threaded mounting hole on the chassis to carry out clamping to thin-walled parts, inner circle to thin-walled parts, cylindrical and end face are processed processing, thereby solved lathe pawl dish and directly the thin-walled parts clamping has been caused workpiece deformation, improved the machining accuracy of part, lightening hole on the chassis has reduced the weight on chassis, convenient operation is installed, compare with traditional diamond-making technique, improved working (machining) efficiency, guaranteed the machining accuracy of workpiece, reduced the loss that workpiece deformation brings.
Description of drawings
For the purpose, technical scheme and the advantage that make utility model is clearer, below in conjunction with accompanying drawing, the utility model is described in further detail, wherein:
Fig. 1 is front view of the present utility model;
Fig. 2 is the first embodiment schematic diagram of the present utility model;
Fig. 3 is the second embodiment schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
Fig. 1 is front view of the present utility model, as shown in the figure, a kind of lathe clamp for machining, comprise chassis 1, have centre bore 2, briquetting installing hole 3 and threaded mounting hole 4 on described chassis 1, described centre bore 2 is positioned at 1 center, chassis, and described briquetting installing hole 3 is positioned at 1 middle part, chassis and around centre bore 2 annular array, and described threaded mounting hole 4 is positioned at 1 end, chassis and around centre bore 2 annular array.
Fig. 2 is the first embodiment schematic diagram of the present utility model, as shown in the figure, part 10 is fixed on chassis 1 by briquetting 7, part 10 centers are concentric with center chassis hole 2, compress by briquetting installing hole 3 use bolts 8, the quantity of briquetting installing hole 3 can arrange corresponding quantity according to part 10, lathe pawl dish carries out clamping to chassis 1 again, the distortion that can avoid the part 10 of thin wall to produce because of the direct clamping of pawl dish, start lathe, inner circle to part 10, cylindrical and end face are processed, not only can guarantee the machining accuracy of workpiece, can also prevent the distortion of workpiece.
Fig. 3 is the second embodiment schematic diagram of the present utility model, as shown in the figure, part 10 is fixed on chassis 1, by the One On The Chassis threaded mounting hole 4, utilize 9 pairs of parts 10 of screw to compress, the quantity of threaded mounting hole 4 can arrange corresponding quantity according to part 10, lathe pawl dish carries out clamping to chassis 1 again, the distortion that can avoid the part 10 of thin wall to produce because of the direct clamping of pawl dish, start lathe, inner circle, cylindrical and end face to part 10 are processed, and not only can guarantee the machining accuracy of workpiece, can also prevent the distortion of workpiece.
Further improvement as the second embodiment, the one side on described chassis 1 is provided with the circular groove 5 concentric with centre bore 2, is convenient to when processing thin-walled flange, and the flange protruding end is embedded in circular groove 5, avoid end face of flange to add man-hour, produce distortion during because of briquetting 7 or screw 9 compression.
In the present embodiment, have lightening hole 6 on described chassis 1, alleviate the weight on chassis 1, make workman's more convenient and quicker when using chassis 1 clamping thin-walled parts 10, increase work efficiency.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although by the utility model being described with reference to preferred embodiment of the present utility model, but those of ordinary skill in the art is to be understood that, can make various changes to it in the form and details, and not depart from the spirit and scope of the present utility model that appended claims limits.
