Abstract
The utility model discloses a kind of rocker arm shaft positioning fixture, solving fine tuning structure complexity that existing rocker arm shaft fixture exists, be not easy to the problem of operation.Rocker arm shaft positioning fixture, comprise grip block and pressing plate, the middle part of described grip block is the first V-arrangement holding tank, the cell wall both sides that are positioned at holding tank in grip block are respectively equipped with the first screw rod and the second screw rod, grip block is all stretched out in one end of two screw rods, the first axle sleeve has been threaded on the first screw rod, the second axle sleeve has been threaded on the second screw rod, two axle sleeves all with the both ends empty set of pressing plate, the end of the first axle sleeve is stretched out pressing plate and is connected with one handle, and the end of the second axle sleeve is stretched out pressing plate and fixed by nut.This fixture just can be realized the fine setting of rocker arm shaft clamping position by simple nut, axle sleeve and screw-rod structure.
Description
Technical field
The utility model relates to Machining Technology, is specifically related to a kind of rocker arm shaft positioning fixture.
Background technology
fixture is widely used in the manufacture processing of workpiece, and considers the demand of the processing and manufacturing cost that as far as possible reduces workpiece, and General Requirements clamp structure is simple, convenient operation.At present, rocker arm shaft is added to man-hour, in order to ensure machining accuracy, in the time of clamping position, conventionally need to finely tune the clamping degree of rocker arm shaft, and the fine tuning structure of existing rocker arm shaft fixture is often comparatively complicated, is not easy to operation.
Utility model content
The utility model provides a kind of rocker arm shaft positioning fixture, solving fine tuning structure complexity that existing rocker arm shaft fixture exists, be not easy to the problem of operation.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
Rocker arm shaft positioning fixture, comprise grip block and pressing plate, the middle part of described grip block is the first V-arrangement holding tank, the cell wall both sides that are positioned at holding tank in grip block are respectively equipped with the first screw rod and the second screw rod, grip block is all stretched out in one end of two screw rods, the first axle sleeve has been threaded on the first screw rod, the second axle sleeve has been threaded on the second screw rod, two axle sleeves all with the both ends empty set of pressing plate, the end of the first axle sleeve is stretched out pressing plate and is connected with one handle, and the end of the second axle sleeve is stretched out pressing plate and fixed by nut.
This fixture operation principle is as follows: the first axle sleeve is connected with screw flight, turning handle, the first axle sleeve is moved to grip block direction, because the two ends of pressing plate are respectively with the first axle sleeve and the second axle sleeve empty set, handle is positioned at a pressing plate side of grip block dorsad, therefore, handle will promote pressing plate to grip block direction rapid movement, until pressing plate contacts holding workpiece with workpiece, now can be as required, make the nut on the second axle sleeve unclamp a segment distance, or after fastening nut, make the second axle sleeve on the second screw rod, readvance segment apart from the clamping dynamics of finely tuning workpiece, thereby make workpiece location more accurate, machining accuracy is higher.
Further, a side that is positioned at workpiece at described pressing plate is provided with the second V-arrangement holding tank.The second V-arrangement holding tank coordinates holding workpiece with the first V-arrangement holding tank, increases the clamping position face of workpiece, can improve the stability of rocker arm shaft clamping.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model rocker arm shaft positioning fixture embodiment.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Rocker arm shaft positioning fixture as shown in Figure 1, comprise grip block 1, pressing plate 2, the first screw rod 3, the second screw rod 4, the first axle sleeve 5, the second axle sleeve 6, handle, nut 8 and the second V-arrangement holding tank 9, the middle part of grip block 1 is the first V-arrangement holding tank, the cell wall both sides that are positioned at holding tank in grip block 1 arrange respectively the first screw rod 3 and the second screw rod 4, grip block 1 is all stretched out in one end of two screw rods, the first axle sleeve 5 is threaded on the first screw rod 3, the second axle sleeve 6 is threaded on the second screw rod 4, two axle sleeves all with the both ends empty set of pressing plate 2, the end of the first axle sleeve 5 is stretched out pressing plate 2 and is connected with handle 7, it is fixing by nut 8 that pressing plate 2 is stretched out in the end of the second axle sleeve 6, a side that is positioned at workpiece at pressing plate 2 arranges the second V-arrangement holding tank 9.
This fixture operation principle is as follows: the first axle sleeve is connected with screw flight, turning handle, the first axle sleeve is moved to grip block direction, because the two ends of pressing plate are respectively with the first axle sleeve and the second axle sleeve empty set, handle is positioned at a pressing plate side of grip block dorsad, therefore, handle will promote pressing plate to grip block direction rapid movement, until pressing plate contacts holding workpiece with workpiece, now can be as required, make the nut on the second axle sleeve unclamp a segment distance, or after fastening nut, make the second axle sleeve on the second screw rod, readvance segment apart from the clamping dynamics of finely tuning workpiece.
