Abstract
The shell turning clamp comprises a disc chuck fixed on a machine tool connecting disc, the end face of the disc chuck is a small end face positioning face of a power take-off shell, a hook-shaped pressing plate is transversely installed at the front end of the disc chuck, and the end of the hook-shaped pressing plate is clamped and connected with the large end face of the power take-off shell. The shell turning clamp adopts a press-fitting mode, takes the end face of a workpiece as a reference surface for positioning, and tightly presses the other end face, so that the original clamping of chuck claws is changed, the clamping deformation is avoided, the error caused by the deformation of an inner hole due to overlarge clamping force is eliminated, and the machining size of the shell and the roundness precision of the inner hole are ensured.
Description
Technical Field
The utility model relates to the technical field of clamps, in particular to a clamp for machining a power takeoff shell.
Background
Along with the increase of infrastructure investment, the power takeoff product demand of fitting in the engine also increases thereupon, and the casing is the important subassembly of power takeoff assembly, and the casing is the casting piece, and its structural feature is that the wall is thin, the outer circular shape is irregular, and the hole size is bigger than a bit, adopts traditional chuck jaw clamping mode to carry out lathe work, causes the centre gripping to warp easily, and the size and the hole circularity precision of processing out are poor, can not satisfy the drawing requirement to influence assembly precision and performance.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems of the traditional power takeoff shell machining mold, the utility model provides a power takeoff shell machining clamp.
The technical scheme adopted by the utility model for realizing the purpose is as follows: the shell turning clamp comprises a faceplate 2 fixed on a machine tool connecting plate 1, a faceplate end face 11 of the faceplate 2 is a small end face positioning face of a power takeoff shell 9, a hook-shaped pressing plate 7 is transversely installed at the front end of the faceplate 2, and the end part of the hook-shaped pressing plate 7 is tightly clamped and connected with the large end face of the power takeoff shell 9.
A groove is transversely formed in the hook-shaped pressing plate 7, the hook-shaped pressing plate 7 is fixed on the faceplate 2 through a pressing plate screw 8 penetrating through the groove, and a spring 6 is arranged in the groove and positioned on the outer side of the pressing plate screw 8.
And a positioning block screw 5 is longitudinally arranged in the middle of the faceplate 2, and an auxiliary positioning block 4 is arranged between the front end of the positioning block screw 5 and the power takeoff shell 9.
The shell turning clamp adopts a press-fitting mode, positions the end face of a workpiece by taking the end face as a reference surface, and compresses the other end face, so that the original chuck jaw clamping is changed, the clamping deformation is avoided, the error caused by the deformation of an inner hole due to overlarge clamping force is eliminated, and the shell machining size and the roundness precision of the inner hole are ensured.
Drawings
FIG. 1 is a front sectional view of the housing turning jig of the present invention.
In the figure: 1. the machine tool comprises a machine tool connecting disc, 2, a faceplate, 3, a faceplate fixing screw, 4, an auxiliary positioning block, 5, a positioning block screw, 6, a spring, 7, a hook-shaped pressing plate, 8, a pressing plate screw, 9, a power takeoff shell, 10, a machine tool spindle end face, 11 and a faceplate end face.
Detailed Description
The power takeoff shell turning clamp structure is shown in figure 1 and comprises a faceplate 2 fixed on a machine tool connecting plate 1, wherein a faceplate end face 11 of the faceplate 2 is a small end face positioning face of a power takeoff shell 9, a hook-shaped pressing plate 7 is transversely installed at the front end of the faceplate 2, the end part of the hook-shaped pressing plate 7 is tightly clamped and connected with a large end face of the power takeoff shell 9, a groove is transversely formed in the hook-shaped pressing plate 7, the hook-shaped pressing plate 7 is fixed on the faceplate 2 through a pressing plate screw 8 penetrating through the groove, and a spring 6 is arranged in the groove and positioned on the outer side of the pressing plate screw 8. A positioning block screw 5 is longitudinally arranged in the middle of the faceplate 2, and an auxiliary positioning block 4 is arranged between the front end of the positioning block screw 5 and the power takeoff shell 9.
The faceplate 2 is connected with a machine tool connecting plate 1 through a faceplate fixing screw 3, the auxiliary positioning block 4 is positioned in an auxiliary way through a positioning block screw 5, and the hook-shaped pressing plate 7 is pressed on the end face of the shell through a pressing plate screw 8. The end face of a workpiece is used as a reference surface for positioning, the other end face of the workpiece is pressed tightly, the end face of the shell is attached to the end face 11 of the faceplate, the auxiliary positioning block 4 fastens the shell through the screwing screw 5, and then the end face of the hook-shaped pressing plate 7 is pressed tightly with the large face of the end of the shell 9 through the pressing plate screw 8. When the positioning device is used, the small end face of the shell 9 is positioned, the screw 5 is screwed down to enable the auxiliary positioning block 4 to be positioned in an auxiliary mode, the hook-shaped pressing plate 7 is pressed against the large end face of the shell 9 to machine an inner hole, and the requirement for machining accuracy can be met completely.
