A kind of workpiece go-cart of drying room case
Technical field
The present invention relates to a kind of fluorine and mould the workpiece transport in the workpiece sintering drying room case, relate in particular to a kind of workpiece go-cart of drying room case.
Background technology
Fluorine is moulded the workpiece sintering typing and generally all in the drying room case, is carried out; Because the temperature in the drying room case could be moulded the workpiece sintering typing with the fluorine of making about will be up to 400 ℃; To use the workpiece go-cart so fluorine is moulded the conveying of workpiece; Workpiece go-cart commonly used now adopts iron tyre in the 15# rail, to roll more, is moved back and forth back and forth by motor deceleration case traction go-cart.Such workpiece go-cart; Its iron tyre can't use lubricating oil because of the high temperature of baking oven; Can only dry friction on rail, thus the iron tyre that makes go-cart can the great frictional force of generation in moving, and can make iron tyre kill on rail and can not roll in the course of time; Cause at last producing and stop breaking, reduced production efficiency.
Summary of the invention
The invention provides a kind of workpiece go-cart of drying room case, continual and steady when it carries fluorine to mould workpiece, can not kill.In order to realize the foregoing invention purpose, the present invention has adopted following technological means:
A kind of workpiece go-cart of drying room case comprises the workpiece go-cart that can move around in orbit; Said track top is provided with the track notch of V-type; Said workpiece go-cart bottom is provided with the go-cart notch of V-type; Said track notch is mid-to have ball, and said go-cart notch is buckled on the ball.
Beneficial effect of the present invention is: the mode that adopts ball to roll moves around the workpiece go-cart on rail, greatly reduced frictional force, has avoided fully killing the damp production that on rail, causes because of the workpiece go-cart.
Description of drawings
Fig. 1 is the structural representation of the workpiece go-cart of a kind of drying room case of the present invention;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the preferred implementation of the workpiece go-cart of a kind of drying room case of the present invention is made detailed description:
As depicted in figs. 1 and 2, the workpiece go-cart of this drying room case mainly is made up of track 3 and the workpiece go-cart 1 that on track 3, moves around; Track 3 is two parallel rail, and the top of every one steel rail is V-shaped, and the V-type opening forms track notch 31 up, and the track notch 31 of V-type is built-in with the ball 2 of several steel; The bottom of workpiece go-cart 1 is installed with two go-cart notches 11 through welding, and go-cart notch 11 is also V-shaped, and the V-type opening down; Two go-cart notch 11 parallel settings; Itself and line space and track 3 and line space equate that go-cart notch 11 is buckled in the top of ball 2, ball 2 contacts with 31 2 of the maintenances of track notch; Ball 2 also keeps contact at 2 with go-cart notch 11, thereby makes workpiece go-cart 1 and track 3 be slidingly matched.
In the time of the workpiece go-cart work of this drying room case, motor deceleration case traction workpiece go-cart 1 moves it, under the effect of ball 2; Workpiece go-cart 1 can move around on track 3; Contact because ball 2 keeps at 2 with track notch 31, ball 2 also keeps contact at 2 with go-cart notch 11, so ball 2 and track 3 or all very little with the frictional force of workpiece go-cart 1; Basically do not need the lubricated of lubricating oil; Motor just can draw workpiece go-cart 1 very easily, makes its natural flexibly transportation fluorine mould workpiece, and effect is very good.
