Line motor.
To achieve the goals above, the technical solution adopted in the utility model is as follows：
A kind of linear motor protective device, using channel steel as holder, channel steel is laterally located, in the top trepanning installation of channel steel
Axis is used in combination nut I to fix axis, passes through axis, axle sleeve shock mount and backing plate, backing plate to be mounted on spring upper end, lead guide bearing
It is equipped with the counterbore that coordinate with backing plate to the lower end of bearing, the top of the plain bearing of polyurethane ball bearing or outsourcing polyurethane is pacified
Loading nut II, nut II screw in axis, guide bearing are fixed on axis by nut II, spring and backing plate, and the following of channel steel is led to
It crosses screw to fix, the outer surface of the guide bearing is equipped with cushioned material layer.
As optimal technical scheme, the guide bearing is polyurethane ball bearing or the poly- ammonia of plain ball bearing outsourcing
Ester.
Further include sliding block, bottom plate, sliding micro machine as optimal technical scheme, the following of channel steel is fixed by screws in
On sliding block, sliding slot is opened up in bottom plate, sliding block is mounted in sliding slot, and sliding block is fixedly connected with the output shaft of sliding micro machine, is slided
Micro machine is fixed on bottom plate.
As optimal technical scheme, pressure sensor is installed on the axis, the connection sliding of pressure sensor connection signal is micro-
Motor.
More specifically, linear motor protective device shares bottom plate, the both ends respectively installation two of linear motor with linear motor
Linear motor protective device, the spacing of two straight line protective devices are matched with the air gap of linear motor.
When linear motor is run, motor plate can ceaselessly pass through linear motor, under the action of protective device, if electric
Machine plate will hit linear motor, and the polyurethane bearing being mounted on an axle can start to rotate under the drive of motor plate, and will be electric
Machine plate is kept off in the central channel of linear motor.Polyurethane bearing will not also scratch motor plate simultaneously.
The utility model has the advantages that following：
1. delicate structure, easy to install and use, the height of guide bearing is easy to adjust；
2. installation dimension is adjustable, the spacing of guide bearing is easy to adjust, can be big according to the pressure suffered by guide bearing
Small automatic adjustment spacing is suitable for the linear motor of different model；
3. safeguard function is strong, the outer surface of guide bearing is equipped with cushioned material layer, and noise is small.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
