Abstract
The utility model relates to a machining fixture for adjusting the positioning eccentric distance of an eccentric shaft part. The machining fixture comprises a base, a sliding seat, a screw rod and a clamping block. The front end face of the base is connected with the sliding seat through a guide rail pair, the sliding seat linearly moves along the guide rail pair on the base through the adjustable screw rod, and the front end of the sliding seat is provided with the clamping blocks. A positioning block is arranged on the base located on the side face of the sliding seat, the positioning block is provided with a measuring bar, and a measuring meter is arranged on the side face, corresponding to the upper end of the positioning block, of the sliding seat. According to the machining fixture, the visible measuring meter with higher accuracy is arranged on the adjusting link, the measuring bar is combined to be used, and the relevant problems are better solved. The machining fixture is convenient to operate, saves adjusting time and improves efficiency and accuracy of the cylindrical grinding of an eccentric shaft neck of the eccentric shaft part.
Description
Technical field
The utility model relates to a kind of machining fixture, especially a kind of machining fixture that can fine adjustment eccentric shaft part location eccentricity distance.
Background technology
The machining fixture of existing eccentric adjustment axle part eccentric throw, general not tool for mounting has the visual measuring instrument of degree of precision, often cause trace to regulate inconvenience, it is not high that eccentric throw is adjusted precision, especially in recent years, the eccentric throw of the eccentric shaft parts such as engine crankshaft requires dimensional accuracy more and more higher, and original machining fixture has been difficult to meet its requirement.
Summary of the invention
For overcoming the deficiencies in the prior art part, the utility model provides a kind of machining fixture and using method thereof that can fine adjustment eccentric shaft part location eccentricity distance, and it has simple and reasonable, easy to operate, precision high.
The utility model is achieved through the following technical solutions:
A kind of machining fixture of eccentric adjustment axle part location eccentricity distance, comprise base, slide, screw mandrel, fixture block, be characterized in: on base front end face, connect slide by guideway, and slide is by regulating screw mandrel along the guideway rectilinear movement on base, slide front end is provided with fixture block.
The described base that is positioned at slide side is equipped with locating piece, places length bar on locating piece, and measuring instrument is equipped with in slide side and corresponding section, locating piece upper end.
The beneficial effects of the utility model are:
The utility model by installing the visual measuring instrument with degree of precision on adjustment link, and the use of combined standard length bar, has solved relevant issues preferably.This utility model is easy to operate, has saved the adjustment time, has improved the efficiency and precision of eccentric shaft part rotor journal Excircle machining.This device, for machining tool, is installed on the rotary main shaft of frame end to end of lathe, in the time of machined eccentric shaft part rotor journal, uses, and frame axis of rotation is consistent end to end to make rotor journal axis one, is convenient to revolution processing.
Brief description of the drawings
Fig. 1 is that axle of the present utility model is surveyed view.
Detailed description of the invention
Below in conjunction with accompanying drawing and example, the utility model is described in further detail.
As shown in Figure 1, the machining fixture of eccentric adjustment axle part location eccentricity distance of the present utility model, comprises base 1, locating piece 2, length bar 3, measuring instrument 4, slide 5, screw mandrel 6, fixture block 7.
On base 1 front end face, connect slide 5 by guideway, and slide 5 by screw mandrel 6 along the adjustable connection of guideway straight line on base 1, slide 5 front ends are provided with fixture block 7.The base 1 that is positioned at slide 5 sides is equipped with locating piece 2, places standard length bar 3 on locating piece 2, and measuring instrument 4 is equipped with in slide 5 sides and locating piece 2 corresponding sections, upper end.Grip device uses measuring instrument 4 and length bar 3, the distance that can accurately observe eccentric shaft part installing hole axis and axis of rotation, then by fine setting screw mandrel 6, make it consistent with the eccentric throw of eccentric shaft part.
This grip device is generally installed on the rotary main shaft of the frame end to end axle head of lathe, eccentric shaft part 8 is clamped by fixture block 7, be arranged in slide 5 holes with higher position precision, slide 5 is by regulating screw mandrel 6 to do rectilinear motion along base 1 upper rail pair, to reach rational offset or dish.Use measuring instrument 4 and length bar 3, can accurately observe the distance between 4 times contacts of measuring instrument and locating piece 2, it is the distance of eccentric shaft part 8 installing hole axis and axis of rotation, again by fine setting screw mandrel 6, make it consistent with the eccentric throw of eccentric shaft part 8, now, rotor journal axis overlaps with axis of rotation.Then pass through screw lock, the position relationship between fixing slide carriage 5 and base 1.
The utility model increases the visual measuring instrument with degree of precision on adjustment link, in conjunction with the use of length bar, has solved preferably relevant issues.Have easy to operately, saved the features such as adjustment time, the clamping precision while also having improved eccentric shaft part rotor journal Excircle machining, and then improve mach efficiency and precision.
