Abstract
The utility model relates to a shell eccentric machining tool which comprises a rear fixing board, a front fixing board and a three-claw chuck. The rear fixing board is arranged on a main shaft of a lathe. The front fixing board is fixedly arranged on the rear fixing board. The three-claw chuck is fixedly arranged on the front fixing board. Two locating holes corresponding in position are formed in the front fixing board. A locating pin penetrates through one locating hole so that the front fixing board can be fixed. The front fixing board is located through the two locating holes, the use rate of a common lathe is fully considered, the use rate of a machining center is reduced, production cost is reduced, and according to the similar triangle principle, control over the eccentric distance and other sizes of a product can be guaranteed through tool displacement in the machining process.
Description
Technical field
The utility model relates to a kind of processing tool, is specifically related to a kind of housing eccentric processing frock.
Background technology
In the process of machine tooling, often run into columniform housing, and the diameter of enclosure interior is different, the method for conventionally processing this workpiece is, first processes the part that diameter is large, after machining, takes off product, changes after frock retightens, then processes.In said method, the process of replacement of products frock trouble, dismounting inconvenience, wastes man-hour, and operating efficiency is very low.
Utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, and a kind of housing eccentric processing frock of dismantling product, increasing work efficiency of not needing is provided.
In order to solve above technical problem, the utility model provides a kind of housing eccentric processing frock, comprise rear fixed plate, front shoe and scroll chuck, described rear fixed plate is arranged on the main shaft of lathe, described front shoe is fixedly installed on described rear fixed plate, and described scroll chuck is fixedly installed on described front shoe, wherein, two locating holes that position is corresponding are set on described front shoe, and described front shoe passes one of them locating hole by alignment pin and fixes.
Being further defined to of technical solutions of the utility model, the cross section of described locating hole is circular, the distance of center circle between two locating holes on same plane is 3.5mm.
Further, described front shoe is identical with the size shape of described rear fixed plate.
Further, described scroll chuck is fixedly installed on the center of described front shoe.
The beneficial effects of the utility model are: a kind of housing eccentric processing frock that the utility model provides, utilize two locating holes that front shoe is positioned, take into full account the utilization rate of engine lathe, reduce the utilization rate of machining center, reduce production costs, by similar triangular form principle, utilize frock in process to be shifted to guarantee the control of product eccentric throw and the control of each other sizes.
Accompanying drawing explanation
Structural representation when Fig. 1 is the large footpath of housing eccentric processing fixture vehicle of the present utility model;
Structural representation when Fig. 2 is housing eccentric processing fixture vehicle path of the present utility model.
The specific embodiment
embodiment 1
A kind of housing eccentric processing frock that the present embodiment provides, comprises rear fixed plate 1, front shoe 2 and scroll chuck 3.
Rear fixed plate 1 is arranged on the main shaft of lathe, and front shoe 2 is fixedly installed on rear fixed plate 1, and front shoe 2 is identical with the size shape of rear fixed plate 1, is circle in the present embodiment.
Scroll chuck 3 is fixedly installed on described front shoe 2, and in the present embodiment, scroll chuck 3 is fixedly installed on the center of front shoe 2, and the effect of scroll chuck 3 is that housing to be processed 4 is fixed on front shoe.
Two locating holes 5 that position is corresponding are set on front shoe 2, and front shoe 2 is fixing through one of them locating hole 5 by alignment pin 6.In the present embodiment, the cross section of locating hole 5 is circular, and the distance of center circle between two locating holes 5 on same plane is 3.5mm, is convenient to process the housing of 3.5mm eccentric throw.
During the large footpath of the frock processing housing providing when the present embodiment, alignment pin 6, through the locating hole 5 in outside, as shown in Figure 1, is processed the large footpath of housing 4; During the path of the frock processing housing providing when the present embodiment, alignment pin 6, through the locating hole 5 of inner side, as shown in Figure 2, is processed the path of housing 4.
The present embodiment utilizes two locating holes that front shoe is positioned, take into full account the utilization rate of engine lathe, reduce the utilization rate of machining center, reduce production costs, by similar triangular form principle, utilize frock in process to be shifted to guarantee the control of product eccentric throw and the control of each other sizes.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
