Abstract

The utility model relates to a computerized numerical control (CNC) camshaft milling machine, in particular to an aligning device for a CNC camshaft milling machine workpiece. The device is characterized in that the aligning device comprises a positioning body (4) fixed on a worktable (5); the positioning body (4) is connected with one end of a bending plate (2) through a pin shaft (3); and an adjusting screw (1) which is matched with a part to be processed is fixed at the other end of the bending plate (2). The aligning device comprises a bracket, the bending plate, the adjusting screw and the like; before the utility model is processed, the position of the aligning device only needs to be adjusted; and during the following processing, the workpiece is only rotated, the datum mark of the workpiece can be tangential to the tip part of the adjusting screw. The utility model has the advantage of simple and convenient operation.

Description

CNC-camshaft milling machine workpiece alignment device

Technical field

The utility model relates to CNC-camshaft milling machine, especially CNC-camshaft milling machine workpiece alignment device.

Background technology

CNC-camshaft milling machine is applicable to all kinds of automobile brake camshafts of processing, has high rigidity, the characteristics that cutting power is big.Lathe has three main shafts, and special fixture is housed on the workbench, and workpiece can be finished the Milling Process of cam external form automatically and continuously behind a clamping, be a kind of highly-efficient processing mode, can be used for the production of extensive batch machining camshaft.

Cam is a black skin at its profile to be processed of first being processed, if the deviation of setting in the direction of cam and the system will occur too greatly that some places cut too dark and situation that some places are not also cut.

The utility model content

The purpose of this utility model provides a kind of simple in structure, and is easy to use, and has the CNC-camshaft milling machine workpiece alignment device of high orientation precision.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of CNC-camshaft milling machine workpiece alignment device, its special feature is, comprises the positioning body that is fixed on the workbench, this positioning body is connected with an end of a bent plate by bearing pin, is fixed with the adjustment screw that cooperates with part to be processed on the other end of this bent plate.

Wherein adjusting between screw and the bent plate is that bolt is connected.

Wherein the cross section of bent plate is " L " type.

The utility model is made up of support, bent plate, adjustment screw etc., processes preceding only the need and adjusts the position of looking for device, and processing after this only needs rotational workpieces, and tangent the getting final product in tip that allows workpiece datum mark and adjustment screw operated very simple and convenient.

Description of drawings

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is a structural representation of the present utility model.

The specific embodiment

Come the utility model is described in further detail below in conjunction with accompanying drawing:

As shown in Figure 1, 2, cam is a black skin at its profile to be processed of first being processed, if the deviation of setting in the direction of cam and the system is too big, will occur that some places cut too dark and situation that some places are not also cut, workpiece alignment device of the present utility model has well solved this problem.

After using this device that workpiece is carried out centering, by clamping button, workpiece is clamped, and this moment, the bent plate 2 with alignment device overturn 180 °, pressed the loop start button, and processing is formally carried out.

Adjustment screw 1 end of alignment device is through special thermal treatment, and is superpower wear-resistant, and reusable up to ten thousand times, and possess very high precision stability, the user is hardly with being that this part of replacing is worried.

Claims
