Description

Cam orientation fixture

Technical field

The utility model relates to a kind of cam orientation fixture, relate more specifically to a kind of used in the cam cutting process Cam orientation fixture.

Background technique

Traditionally, cam cutting process is divided into two parts: heat treatment and turning, and is set by material frame to connect heat treatment Standby and turning equipment.During being moved to turning equipment by Equipment for Heating Processing, needs cam orientation and be placed on material frame. It such as cannot accurately place, will lead to equipment downtime, product abandonment.Salient point detection generally is carried out come to convex to cam using sensor Wheel is positioned.However, the external molded line due to every kind of cam is different, is positioned merely, caused in production process using sensor Product abandonment rate is high, causes to waste.Thus, cam orientation needs further improvement during cam cutting.

Utility model content

Therefore, the utility model aim is to provide a kind of cam orientation fixture, and the cam orientation fixture is fixed by sensor Position and fixture positioning, ensure that more accurate cam orientation.

In order to realize foregoing purpose, the cam orientation fixture that the utility model is proposed includes:

First fixture is used to clamp the basic circle of cam；

Second fixture is used to clamp the peach tip of cam；

Sensor is used to carry out salient point detection to cam；And

Relatively-movable first and second fixed station, the first fixture are mounted on the first fixed station, and the second fixture It is mounted on the second fixed station with sensor.

One embodiment according to the present utility model further includes driving device, and the first fixed station and second is driven to fix Platform relative movement.

One embodiment according to the present utility model, the first fixture has two point form idler wheel, to contact the basic circle of cam.

One embodiment according to the present utility model, wherein the second fixture has the push plate with inclined surface, convex to contact The peach tip of wheel.

Compared with prior art, the utility model has the advantage that

1, it is positioned by sensor positioning and fixture, ensure that more accurate cam orientation, avoid due to using merely The problem of sensor positions and causes product abandonment rate height in production process and waste.

2, the cam with different cam profiles can be positioned.

Detailed description of the invention

By reading the following detailed description of the preferred embodiment, various other advantages and benefits are common for this field Technical staff will become clear.The drawings are only for the purpose of illustrating a preferred embodiment, and is not considered as practical to this Novel limitation.And throughout the drawings, identical component is presented with like reference characters.In the accompanying drawings:

Fig. 1 is the cross-sectional view of the cam orientation fixture of the utility model.

Fig. 2 is the top view of the cam orientation fixture of the utility model.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

As shown in Figure 1, showing the cam orientation fixture of the utility model.By the attached drawing as it can be seen that cam orientation fixture packet Include the peach tip fixture 3 of the peach tip for the basic circle fixture 2 of the basic circle of positioning cam 1 and for positioning cam 1.Basic circle fixture 2 is pacified On the first fixed station 4, peach tip fixture 3 is mounted on the second fixed station 5.First fixed station 4 and the second fixed station 5 are by drive Dynamic cylinder 6 drives, so that the first fixed station 4 and the second fixed station 5 can relatively move.

As shown in Fig. 2, basic circle fixture 2 contacts the basic circle of cam 1 using two point form idler wheel 7, and peach tip fixture 3 includes band There is the push plate 8 of inclined surface to contact the peach tip of cam 1, is positioned so as to different cam profiles.

As depicted in figs. 1 and 2, sensor 9 is arranged on the second fixed station 5, to carry out salient point detection to cam 1.

The course of work of the cam orientation fixture is as follows:

1, cam 1 is placed in support shaft 10, carries out salient point detection with sensor 9, cam is once positioned.

2, after once position to cam, driving cylinder 6 drives the first fixed station 4 and the relative movement of the second fixed station 5, Clamp basic circle fixture 2 to the basic circle of cam 1, peach tip fixture 3 clamps the peach tip of cam 1, thus to cam reality Existing secondary positioning.

The cam orientation fixture of the utility model is able to achieve following functions:

1, it is positioned using purely mechanic contact, magnetic influence will not be generated to cam inside, will not have shadow to the result of heat treatment It rings, ensure that the precision of heat treatment.

2, it is accurately located according to the shape of cam and characteristic.After carrying out coarse positioning by sensor, then to cam Basic circle and peach tip position carry out secondary positioning, make it guarantee thus to complete to be accurately positioned, and be transferred to down in fixed angle One station.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
