The anti-skid device of automatic pouring machine
Technical field
The utility model belongs to the Casting Equipment field, particularly a kind of anti-skid device of automatic pouring machine.
Background technology
On foundry production line, automatic pouring machine need be followed manufacturing line sand mold is carried out automatic casting.In order to realize the motion of automatic pouring machine, it is installed on the travelling car usually.When cast finished parking, travelling car can continue to front slide owing to effect of inertia.For preventing that travelling car just need be provided with anti-skidding mechanism to front slide on cating machine.At present cating machine adopts structure that wheel and rack is meshed as anti-skidding mechanism usually, but there are following several point defects in this anti-skidding mechanism: 1. because the travelling car side travel distance of cating machine is very long, needing to install the tooth bar that matches with its movable length realizes anti-skidding, therefore cause anti-skidding mechanism cost to rise, and then increased the productive costs of enterprise; 2. wheel and rack ingear structure has increased the difficulty of processing, installation and debugging to making and setting accuracy requirement height, has increased the time of manufacturing, installation and debugging, is unfavorable for increasing work efficiency.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of simple in structure, easy for installation, low cost of manufacture is provided, can guarantees effectively that cating machine accurately locatees, prevents travelling car anti-skid device to the automatic pouring machine of front slide when stopping.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of anti-skid device of automatic pouring machine, constitute by travelling car and the motor that is installed on the travelling car, one transmission shaft is installed between the both sides wheel of travelling car, motor output shaft is installed a drive sprocket, this drive sprocket is connected with driven sprocket on being packed in transmission shaft by chain, on the ground in the middle of the wheel of travelling car both sides, install a support, it is characterized in that: the coaxial anti-skidding sprocket wheel that installs in the middle part of transmission shaft, this anti-skidding sprocket wheel is meshed with rack-mount nonskid chain.
And the described motor that is installed on the travelling car is a servomotor.
Advantage of the present utility model and good effect are:
1. the anti-skid device of this automatic pouring machine adopts the mode that anti-skidding sprocket wheel is meshed with nonskid chain, can effectively prevent travelling car when stopping to front slide.Adopt the structural cost of sprocket wheel and chain engages low, therefore can greatly reduce the manufacturing cost of anti-skidding mechanism, thereby strengthen the market competitiveness of enterprise.
2. the structure of employing sprocket wheel and chain engages can also reduce the difficulty of processing, installation and debugging, reduces the time of anti-skid device manufacturing, installation and debugging, has therefore greatly improved work efficiency, has shortened work-hours.
3. chain gear suits to use on the long lane of traffic of miles of relative movement, and chain gear also is adapted at high temperature and bad working environment such as stir up a cloud of dust in use, so the chain-drive structure is particularly suitable for using in foundry production line.
4. the utility model is a kind of anti-skid device of simple in structure, the easy for installation and automatic pouring machine that uses in the mobile occasion of long distance of suiting.The structure that this anti-skid device adopts sprocket wheel to be meshed with chain has reduced manufacturing cost, has improved work efficiency, and can prevent effectively travelling car when parking to front slide.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
The anti-skid device of this automatic pouring machine is made of travelling car 2 and the motor 8 that is installed on the travelling car, and between the both sides wheel 3 of travelling car a transmission shaft 11 is installed.Motor is a servomotor, a drive sprocket 7 is installed on the output shaft of this servomotor, this drive sprocket is connected with the coaxial driven sprocket 5 that is packed on the transmission shaft of wheel with one by chain 6, and drive this driven sprocket rotation, so travelling car can carry cating machine 1 along track 4 side travels.On the ground in the middle of the wheel of the both sides of travelling car, install a support 10.
Innovative point of the present utility model is: the middle part of transmission shaft installs an anti-skidding sprocket wheel 9, and this anti-skidding sprocket wheel can rotate with transmission shaft.Be packed in a nonskid chain 12 is installed on the ground support, this anti-skidding sprocket wheel and nonskid chain engagement are installed.
Principle of work of the present utility model is:
Servomotor is received entry into service after the work order, and the drive sprocket on it drives transmission shaft by chain, driven sprocket and drives travelling car along the track side travel, the also coaxial rotation of the anti-skidding sprocket wheel that installs on the transmission shaft.Simultaneously, anti-skidding sprocket wheel and nonskid chain mesh, and roll forward along nonskid chain.When cast finishes when stopping, servomotor and transmission shaft stop operating, because inertia, travelling car also can be to front slide, but the anti-skidding sprocket wheel that is packed on the transmission shaft is meshed with nonskid chain, have stoped travelling car to front slide.
