Besides, the lathe cutting machining clamp does not produce vibration easily, improves the machining accuracy, and solves the technical problem that the thin and long workpiece is not high in cutting machining accuracy in the prior art.

Description

A kind of lathe grinding clamp for machining

Technical field

The present invention relates to a kind of frock clamp, especially relate to a kind of clamp for cutting for Cutting Process.

Background technology

At present, the processing to slender piece on the lathe is the hilted broadsword cutting, and slender piece is in working angles, it is subjected to radial cutting force to affect flexible distortion, and produces vibration easily, and machining accuracy is not high, operation easier is large, and is high to operator's technology and experience requirement, is difficult to improve the product quality of workpiece.

The utility model content

In order to overcome existing deficiency to the slender piece Machining Technology for Cutting.The utility model proposes a kind of clamp for cutting for Cutting Process, be intended to solve in the prior art to the not high technical problem of slender piece machining precision.

In order to solve the problems of the technologies described above, the technical scheme of the clamp for cutting that the utility model provides is as follows: a kind of lathe grinding clamp for machining has the clamping fixture seat that the bottom cooperates with guide ways on lathe bed; The pipe spreader that is fixedly connected with described clamping fixture seat; The outer ring cooperates clutch shaft bearing and the second bearing that is installed on described pipe spreader both ends; Cooperate the hollow rotating shaft that is installed in described clutch shaft bearing and the second bearing inner race; The ring flange that is fixedly connected with described hollow rotating shaft one end; With the self-centering chuck that described ring flange removably connects, after described clamping fixture seat cooperates on the guide rail that is installed in the body of lathe bed, the chuck concentric of described self-centering chuck and lathe.

Further, the lathe grinding clamp for machining also has the first end cap and the second end cap that is detachably connected on described pipe spreader two ends.

Further, the self-centering chuck of lathe grinding clamp for machining is three-jaw or four paws self-centering chuck.

Further, the lathe grinding clamp for machining also has the hold-down nut that stops hollow rotating shaft to slide in described clutch shaft bearing and the second bearing.

Above-mentioned improvement project can be implemented alone or in combination in the situation of not conflicting.

Self-centering chuck utilizes screw, and the screw by on the disk body seam end face is fastened on chuck on the flange, spanner is inserted in arbitrary gear square hole, and during rotating spanner, pinion drives parcel and rotates, by the rotation of parcel end-face helical, the drive claw becomes simultaneously into or disperses.But the claw radial concentric of self-centering chuck moves and makes the workpiece self-centering, and its structure belongs to known technology in the lathe technical field.

The utility model has following beneficial effect: during work, the lathe grinding clamp for machining is installed on the guide ways on lathe bed, after slender piece passes from the hollow rotating shaft of clamp for cutting, one end grips with the chuck of lathe, self-centering chuck with clamp for cutting grips again, can carry out machining to slender piece, because the chuck of lathe and the self-centering chuck of clamp for cutting are on the same axle center, add the man-hour slender piece and have two fixing points, when being affected by radial cutting force, it is difficult for flexural deformation, and be difficult for producing vibration, improved machining accuracy, thereby solved in the prior art the not high technical problem of slender piece machining precision.

Description of drawings

Accompanying drawing is used to provide further understanding of the present utility model, consists of the application's a part, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not consist of improper restriction of the present utility model.In the accompanying drawings:

Fig. 1 is the structural representation of embodiment clamp for cutting;

Fig. 2 is that the embodiment clamp for cutting uses view.

The specific embodiment

Clamp for cutting has clamping fixture seat 10 as shown in Figure 1, the bottom of clamping fixture seat 10 is provided with groove, cooperate with V-way and the rectangular guideway of the body of lathe bed, accurate location when being convenient to install, pipe spreader 5 is fixedly connected with the top of described clamping fixture seat 10, the both ends of pipe spreader 5 have bearing block, the outer ring of clutch shaft bearing 4 and the second bearing 6 cooperates respectively in the bearing block that is installed in described pipe spreader 5 both ends, hollow rotating shaft 7 cooperations are installed in the inner ring of described clutch shaft bearing 4 and the second bearing 6, ring flange 2 is fixedly connected with the first end of described hollow rotating shaft 7, the first end cap 3 and the second end cap 9 removably are connected to the two ends of described pipe spreader 5 by bolt, three-jaw self-centering chuck 1 and described ring flange 2 removably are fixed together by bolt, after clamping fixture seat 10 cooperates on the V-way that is installed in the body of lathe bed and the rectangular guideway, the chuck concentric of described three-jaw self-centering chuck 1 and lathe.

In other embodiments, self-centering chuck can be four paws self-centering chuck etc.

In other embodiments, can not have the first end cap 3 and the second end cap 9.

In other embodiments, also have to be connected on the hollow rotating shaft 7 and stop hollow rotating shaft 7 at the hold-down nut 8 of described clutch shaft bearing 4 and the 6 interior slips of the second bearing.

As shown in Figure 2, during work, clamp for cutting is installed on lathe 11 bed ways, after slender piece 13 passes from the hollow rotating shaft 7 of clamp for cutting, one end grips with the chuck 12 of lathe 11, self-centering chuck 1 with clamp for cutting grips again, can carry out machining to slender piece 13, because the chuck 12 of lathe 11 self-centering chuck 1 with clamp for cutting is on the same axle center, add the man-hour slender piece and 13 have two fixing points, when being affected by radial cutting force, it is difficult for flexural deformation, and be difficult for producing vibration, improved machining accuracy, thereby solved in the prior art the not high technical problem of slender piece machining precision.

The above only is preferred embodiment of the present utility model, and limits never in any form the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit and principle that the utility model claims disclose, the modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
