Abstract

The utility model relates to the technical field of production of a motor, in particular to a vehicle drilling and machining fixture for an end cover of the motor. The fixture is particularly suitable for machining large-sized thin-wall box bodies and comprises the end cover, an upper assembly and a lower assembly connected with the upper assembly by a locating column, wherein the end cover is arranged on a boss of the lower assembly, fastening bolts leaning against the inner wall of the end cover are arranged on end surface bosses which are symmetrically distributed on the upper end surface of the upper assembly, a compaction support pressing the bottom surface of the end cover is arranged on the lower end surface of the upper assembly along the circumferential direction, and a lower end boss of the lower assembly is provided with an adjusting screw used for adjusting the height of the end cover along the circumferential direction. The fixture can meet the clamping, adjusting and centering needs in the procedures of turning the excircle and the end surface and drilling holes on the end surface; meanwhile , deformation in the machining process is decreased.

Description

The end cap clamp for machining
Technical field
The utility model relates to the motor production technical field, particularly a kind of wagon drill clamp for machining that is used for electric motor end cap.
Background technology
Domestic locomotive necessary electromotor end cap generally all is a disk-like accessory, its processing, clamping generally are to clamp and adjust workpiece by the common claw of lathe, use the pressing plate workpiece pressing, with the circle seam centre of location, its end face is a plane of orientation, adopts the turn-over finish turning, or tightens endoporus with expander and carry out a cutter car, operation is loaded down with trivial details, processes yielding.
For large thin-wall casing class end cap, the master of the GE locomotive necessary electromotor lid of making a start for example, its inner chamber has comprised the auxiliary generator accessory, integrates all functions of support and end cap, and its design feature has determined its clamping, has regulated all very difficulty.The characteristics of this large thin-wall casing class end cap are: its exterior contour does not have and press-fits a little; Its small bore end has boss and the hanger that exceeds, and the small end place is the conical surface.So just cause the difficulty of processing technology: during the big end operation of wagon drill (particularly turner preface), make the common claw of lathe can't clamp and adjust workpiece owing to being subjected to limitation in height; Small bore end is non-machined surface, and big nose end does not have support, and wall is thin, the rigidity extreme difference, and the processing mutability finally causes the installation way of common disk class part and process program not to be suitable on the large thin-wall casing class part.
The utility model content
The purpose of this utility model is, provides a kind of easy to setup and adjust workpiece, reduce the end cap clamp for machining of machining deformation, and this anchor clamps are particularly useful on the large thin-wall casing class part.
A kind of end cap clamp for machining, comprise end cap, top assembly and the lower component that is connected with the top assembly by reference column, end cap is arranged on the boss of lower component, the end face boss that assembly upper surface, described top is symmetrically distributed is provided with the tight fixed bolt that holds out against the end cap inwall, the lower surface is along circumferentially being provided with the support that compresses that compresses the end cap bottom surface, and the boss upper edge, lower end of described lower component circumferentially is provided with the adjustment screw of regulating the end cap height.
The lower end edge of described end cap circumferentially is provided with the soft four paws of increasing that is installed on the interchangeable chuck.
On the lug of described end cap one side limited block is installed.
Middle part, assembly upper surface, described top is along circumferentially being symmetrically arranged with four housing screws.
Described compressing supported symmetrical distribution, and its quantity is to be no less than four even number.
The described adjustment screw of rising is symmetrically distributed, and its quantity is to be no less than four even number.
Owing to adopted technique scheme, the beneficial effects of the utility model are:
1. use and compress support, can make the end cap inner bottom surface clamped.
2. the use tight fixed bolt can prevent end cap inwall machining deformation.
3. use adjustment screw can be regulated the height of end cap.
4. the use limited block can limit end cap along circumferentially rotating.
5. install on the interchangeable chuck and increase soft four paws, can find the center of circle of end cap in the end cap outside.
Description of drawings
Fig. 1 is the utility model structural representation.
Reference numeral: the 1st, top assembly, 1-1 are the end face boss, the 2nd, lower component, 2-1 is a reference column, 2-2 is a boss, the 3rd, bolt, the 4th, compress support, the 5th, tight fixed bolt, the 6th, end cap, the 7th, limited block, the 8th, adjustment screw, the 9th, increase soft four paws.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of end cap clamp for machining, comprise end cap 6, top assembly 1 and the lower component 2 that is connected with top assembly 1 by reference column 2-1, the end face boss 1-1 that assembly 1 upper surface in top is symmetrically distributed is provided with eight tight fixed bolts 5 that hold out against the end cap inwall, produces distortion man-hour in order to prevent that the end cap inwall from adding; The lower surface compresses and supports 4 along circumferentially being provided with eight of compressing the end cap bottom surface; The boss 2-2 upper edge, lower end of lower component 2 circumferentially is provided with four adjustment screw 8 that can regulate end cap 6 height.
Process is as follows: earlier lower component 2 is positioned on the workbench, looks for round reference column 2-1, compress lower component 2 by bolt 3.End cap 6 is arranged on the end face boss 1-1 of lower component 2, regulate adjustment screw 8,, then the interporal lacuna of lower component 2 by reference column 2-1 and top assembly 1 center is connected to adjust the height of end cap 6, rotation top assembly 1 compresses with four bolts 3 then to correct position.Lower end edge at end cap 6 circumferentially is provided with four soft four paws of increasing that are installed on the interchangeable chuck, look for circle in order to the center of circle of externally regulating end cap, limited block 7 is installed on the lug of end cap 6 one sides, and limited block 7 is threaded with end cap 6, the circumferential movement of restriction end cap.So both guarantee the needs of clamping adjusting centering in the big end cylindrical of product (end cap 6) turning, end face and the lead plug end-face hole operation, also reduced the distortion in the process greatly.
Employed in the present embodiment compresses and supports 4, adjustment screw 8 and the quantity of increasing soft four paws 9 are to be no less than 4 even number, and purpose is in order to make firmly equilibrium or assurance level.
