Description
Technical field
The utility model is related to the detecting tool fields of cam, and in particular to a kind of oscillating follower cylindrical lip cam
On-line checking frock.
Background technology
Cam refers to revolution or the sliding part of machinery, and movement is passed to against the idler wheel of its edge movement or in groove face
The shank of upper free movement or it withstood forces from such idler wheel and shank.Cam mechanism is usually by cam, driven member
With the higher pair mechanism of three component compositions of rack.Cam usually makees continuous constant velocity rotation, and driven member designs according to requirements to be made
It obtains the movement of certain rule, and cam mechanism can realize complicated movement needs, is widely used in various automations and semi-automatic
Change in mechanical device.By shape, cam is generally divided into disc cam, translating cam, cylindrical cam, by the forms of motion of driven member
Classification, translating follower and oscillating follower.
Oscillating follower cylindrical lip cam is in process and after the completion of processed finished products, since the work of swing rod is special
Point so that flange dimension is all different in each position.Therefore, it is a problem to the measurement of flange dimension, general measure
Method and cubing can not be completed to measure.Even if measuring flange dimension by dedicated detection device, after a measurement, if it find that
Its is unqualified, it is difficult to which cam is loaded on lathe carries out secondary operation.
Utility model content
The purpose of this utility model is to provide a kind of on-line checking frock of oscillating follower cylindrical lip cam, to solve
Oscillating follower cylindrical lip cam measures the technical issues of difficult in process and after processed finished products.
To achieve the above object, the on-line checking frock of the utility model oscillating follower cylindrical lip cam is using as follows
Technical solution：The on-line checking frock of oscillating follower cylindrical lip cam including swing rod, is equipped with rotating shaft on the upside of swing rod, returns
Shaft is used to be sequentially connected with machine tool chief axis, and rotating shaft axis is equipped with a pair of of roller, roller difference along the vertical direction, on swing rod
It is installed by corresponding Roller Shaft, along the vertical direction, roller is located at below swing rod the axis of Roller Shaft, rotating shaft and Roller Shaft
Installation site is spaced along the longitudinal direction, and the center of rotation of two rollers is on the circular arc using the center of rotating shaft as the center of circle, two rollings
Gap between son forms the test card slot being adapted to flange dimension to be detected.
Further, the roller and Roller Shaft rolling assembling.
Further, the curve size fit of the outer diameter of the roller and cam to be detected.
Further, the swing rod is the platy structure of rectangle.
Further, two Roller Shafts are located on two angles of swing rod respectively.
The beneficial effects of the utility model：Cam is held by a chuck in processing with mandrel clamping, mandrel one end, the other end
With top to top.After machining, the rotating shaft of detecting tool is mounted on machine tool chief axis, cam curve is examined online
It surveys, cam need not dismantle.Machine tool chief axis moves to setting coordinate position along XY horizontal planes, and machine tool chief axis is slowly declined along Z-direction,
Roller is made to drop to real work depth location, two rollers are slowly caught at flange, and clearance gauge can be coordinated to determine between two rollers
Whether gap is suitable.Then slow rotary index head, swing rod, roller are swung with the rotation of cam at this time, if roller is slided with flange
Dynamic smooth, without dead point, then the processing dimension of the cam meets design, requirement.If the size of certain of flange
It is unqualified, after being detected, finishing can be processed directly on lathe, realizes on-line checking, to ensure cam product ruler
It is very little.Solve detection difficult under line, and if after detecting it is unqualified will also again upper machine tooling the problem of.The utility model
Line detecting tool is simple in structure, practical, at low cost.
Description of the drawings
Fig. 1 is that the stereochemical structure of the on-line checking frock embodiment of the utility model oscillating follower cylindrical lip cam is shown
It is intended to；
Fig. 2 is the top view of the on-line checking frock embodiment of the utility model oscillating follower cylindrical lip cam.
Corresponding title is respectively marked in figure：1st, chuck, 2, mandrel, 3, top, 4, cam, 5, flange, 6, rotating shaft, 7, rolling

Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, 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 embodiment in the utility model, those of ordinary skill in the art's all other embodiments obtained all belong to
In the scope of the utility model protection.
The embodiment of the on-line checking frock of the utility model oscillating follower cylindrical lip cam：As Figure 1-Figure 2,
Including swing rod 9,9 upside of swing rod is equipped with rotating shaft 6, and rotating shaft 6 is used to be sequentially connected with machine tool chief axis.6 axis of rotating shaft is along upper
Lower direction, swing rod 9 are equipped with to install the mounting hole of rotating shaft 6.A pair of of roller 8 is installed, roller 8 passes through respectively on swing rod
Corresponding Roller Shaft 7 is installed, and along the vertical direction, roller 8 is located at 9 lower section of swing rod to the axis of Roller Shaft 8.Swing rod 9 is the plate of rectangle
Shape structure.Two Roller Shafts 7 are respectively on two angles of swing rod 9.The installation site of rotating shaft 6 and Roller Shaft is along the longitudinal direction
Interval, the center of rotation of two rollers 8 is on the circular arc using the center of rotating shaft as the center of circle, arc radius R.Between two rollers
Gap forms the test card slot being adapted to flange dimension to be detected.Roller and Roller Shaft rolling assembling.Radius R, roller outer diameter,
Curve size fit of the gap of two rollers with cam to be detected.
The on-line checking frock of the utility model, when in use：Cam 4 is in processing with 2 clamping of mandrel.2 one end of mandrel
It is clamped by chuck 1, top 3 pairs tops of the other end.After machining, detecting tool is mounted on machine tool chief axis, it is bent to cam
Line carries out on-line checking, and cam need not dismantle.Specific detecting step, as shown in Fig. 2, 1), after detecting tool installs, machine
Bed main shaft moves to X, and Y-coordinate position, X, Y-coordinate position is that the swing rod designed according to cam design drawing fixes centre of gyration position
