In addition, the linear encoder transmits the moving distance information of the moving unit to the control unit, and the control unit adjusts the moving speed of the moving unit based on the received moving distance information.

The linear motor mounting base is provided with a sensor for sensing the moving part. When the moving part is sensed, the sensor transmits a sensing signal to the control part, and the control part adjusts the driving of the moving part based on the sensing signal .

Further, the frame portion is provided with a spray nozzle connected to the coolant tank portion and spraying the coolant toward the slide cover.

The slide cover testing apparatus according to the present invention can operate the moving section at a high speed by using the stator and the mover, thereby making it possible to perform a durability test of the high-speed slide cover.

In addition, since the moving part is coupled to the rail part arranged transversely to the frame part, the moving extension part extending from the moving body part in a state where the moving body part is installed on the linear motor guide part, Can be moved.

Also, the control unit not only controls the moving speed of the moving unit based on the moving distance information of the moving unit received from the linear motor encoder, but also allows the moving unit to move while maintaining the set speed.

When the operator operates the moving part 60 in a state where the slide cover 80 is coupled to the moving part 60, the slide cover 80 is slid as the moving part 60 moves. Specifically, when a current flows through the mover 70 installed in the moving part 60, an electromagnetic force is generated between the coil of the mover 70 and the magnet of the stator 50, 5, FIG. 6).

5 and 6, when the moving part 60 is moved to the left (reference in FIG. 5), the slide cover 80 is slid to the left (reference in FIG. 5) along the moving part 60, . Conversely, when the moving part 60 is moved to the right (reference to Fig. 6), the slide cover 80 is overlapped while being slid to the right (reference to Fig. 6) along the moving part 60. [ At this time, the cutting oil is sprayed to the slide cover 80 from the injection nozzle 400 provided in the frame part 20. [ That is, when the moving unit 60 is moved, the control unit 500 actuates the injection nozzle 400 to allow the cutting oil to be sprayed toward the slide cover 80. Therefore, not only the frictional heat generated when the slide cover 80 is moved, but also the operation of the slide cover 80 can be smoothly performed.

In addition, the cutting oil jetted by the slide cover 80 flows into the coolant chamber 11 from the slide cover 80. [ The cutting oil flowing into the cutting oil chamber 11 flows into the cutting oil tank portion 10 along the inclined surface 11a of the cutting oil chamber 11 and the cutting oil flowing into the cutting oil tank portion 10 flows into the cutting oil tank portion 10 again, To the injection nozzle 400. The cutting oil flowing from the coolant tank portion 10 into the injection nozzle 400 is sprayed onto the slide cover 80 and then flows into the coolant tank portion 10 through the coolant chamber 11, 400 can be recycled and sprayed through the injection nozzle 400. [

The linear encoder 100 mounted on the moving part 60 reads the marks of the linear scale 200 and senses the moving distance of the moving part 60. The linear encoder 100 transmits the moving distance information of the moving unit 60 to the control unit 500. The control unit 500 adjusts the moving speed of the moving unit 60 based on the received moving distance information, 60 can reciprocate at a constant speed. In addition, the operator can set the distance by step through the control unit 500 and set the moving unit 60 reciprocating according to the set distance to increase the speed step by step. Thereby, the operator can test the operation and condition of the slide cover 80 by adjusting the speed of the moving part 60 step by step.

A sensor 300 is installed on the left side of the linear motor mounting base 30 as shown in FIG. 4, and the detecting sensor 300 senses a moving part 60 reciprocating leftward (reference to FIG. 4). The sensing sensor 300 transmits a sensing signal to the controller 500, and the controller 500 calculates the number of sensing signals. If the calculated number of times of the sensed signals is equal to the set number of times, the control unit 500 controls the moving unit 60 to stop moving. If the calculated number of times of detection does not reach the preset number, the moving unit 60 is moved to the right (refer to FIG. 4). In this way, the control unit 500 can control the driving of the moving unit 60 so as to maintain the moving unit 60 or stop the moving unit 60 through the sensing sensor 300.

As described above, since the slide cover testing apparatus 1 according to the present embodiment can move at high speed through the stator 50 and the mover 70, it is possible to test the high-speed slide cover 80, The moving speed and the driving of the slide cover testing apparatus 1 can be controlled and the state and operation of the slide cover 80 can be effectively tested.
