Preferably, the second linear displacement device 2 includes a second fixed frame 14, a second servo motor 19, a second screw rod 18, a second nut 16 and a second slider 17 limited to move in the Y-axis direction.

[0036] Preferably, the support frame 20 is a U-shaped frame, the cement board is placed on the top of the support frame 20, and partially protrudes from the top of the support frame 20 for cutting by the cutting device 22.

[0037] The support bracket 20 is located below the first sliding block 9 .

[0038] When the first linear displacement device drives the cutting device 22 to move to the first position and the second position at both ends of the reciprocating motion stroke, the controller controls the second linear displacement device 2 to drive the cement board forward a set distance for cutting by the cutting device 22 . The first position and the second position at both ends of the reciprocating motion stroke are the first linear displacement device driving the cutting device 22 to reciprocate left and right linear movement between the first position and the second position, that is, when the first linear displacement device drives the cutting device 22 to move left to the first position, the controller controls the second linear displacement device 2 to drive the cement board to move forward a set distance, so that the part of the cement board that has not been cut is opposite to the blade of the cutting device 22, and then the controller controls the first linear displacement device to drive the cutting device 22 to move in the opposite direction to the right to cut the cement board. When the cutting device 22 moves right to the second position, the controller controls the second linear displacement device 2 to drive the cement board to move forward a set distance again, so that the part of the cement board that has not been cut is opposite to the blade of the cutting device 22, and then the controller controls the first linear displacement device to drive the cutting device 22 to move in the opposite direction to the left to cut the cement board, so as to realize the reciprocating linear movement of the cutting device 22, and the cutting device 22 can cut the cement board during the reciprocating movement to achieve the test effect.

[0039] The first linear displacement device drives the cutting device 22 to move reciprocatingly in a linear manner to cut the object 21 to be cut, thereby simulating the cutting operation of the manual handheld cutting device 22, and cooperating with the second linear displacement device 2 to feed the material, so as to realize automatic testing of the durability of the cutting device 22. The mechanized operation can perform continuous operation, shorten the test time, improve the test efficiency, save labor, and avoid the manual handheld cutting device 22 from tilting the cutting direction or slipping the cutting position due to fatigue, etc., and can also reduce the risk of injury to workers during cutting testing.

[0040] The interval time for the second linear displacement device 2 to drive the cement board to be fed can be set according to the time it takes the first linear displacement device to drive the cutting device 22 to move from the first position to the second position. For example, if the time it takes the cutting device 22 to move from the first position to the second position is 30s, the second linear displacement device 2 can be set to drive the cement board to be fed forward once every 30s.

[0041] Figure 1 , Figure 2As shown, for example, in the present patent, preferably, a sensor 10 is provided corresponding to the first position and the second position, and the sensor 10 is electrically connected to the controller. When the cutting device 22 moves to one side to the first position or the second position, the sensor 10 transmits a signal to the controller, and the controller controls the second linear displacement device 2 to drive the cement board to move forward a set distance, and the controller controls the first linear displacement device to drive the cutting device 22 to move in the opposite direction. Two sensors 10 are arranged at both ends of the first fixed frame 6 for sensing the first slider 9. When the first slider 9 drives the cutting device 22 to move to the left so that the cutting device 22 moves to the first position on the left, the first slider 9 triggers the sensor 10 on the left, so that the sensor 10 transmits a signal to the controller, and the controller controls the second linear displacement device 2 to drive the cement board to move forward a set distance, and the controller changes the moving direction of the first slider 9 by controlling the rotation direction of the first servo motor 5, so that the first slider 9 drives the cutting device 22 to move to the right. When the first slider 9 drives the cutting device 22 to move to the right so that the cutting device 22 moves to the second position on the right, the first slider 9 triggers the sensor 10 on the right, so that the sensor 10 transmits a signal to the controller, and the controller controls the second linear displacement device 2 to drive the cement board to move forward a set distance, and the controller controls the rotation direction of the first servo motor 5 to change the moving direction of the first slider 9, so that the first slider 9 drives the cutting device 22 to move to the left.

[0042] Preferably, the sensor 10 is a proximity switch, a micro switch or a Hall switch.

[0043] In addition, the cutting device 22 is mounted on the first linear displacement device and is powered by the testing apparatus.

[0044] Figure 1 , Figure 2 , Figure 8 As shown, a feed sensor 11 is provided at the terminal position of the forward feeding of the object 21 to be cut, and the feed sensor 11 is electrically connected to the controller. When the object 21 to be cut moves forward to the terminal position, the feed sensor 11 transmits a signal to the controller, and the controller controls the first linear displacement device and the cutting device 22 to stop working, and the controller controls the second linear displacement device 2 to drive the object 21 to be cut back to the starting position of the feeding. When the object 21 to be cut moves to the terminal position, it means that the cement board has been cut by the cutting device 22, and a new cement board needs to be replaced for the cutting device 22 to cut.

[0045] Figure 1 , Figure 2 , Figure 7As shown, a first alarm is fixed on the frame 1, and a material return sensor 13 is correspondingly provided at the starting position. The first alarm and the material return sensor 13 are both electrically connected to the controller. When the object 21 to be cut returns to the starting position, the material return sensor 13 transmits a signal to the controller, and the controller controls the second linear displacement device 2 to stop working, and the controller controls the first alarm to sound an alarm to remind the workers to replace the new cement board.

[0046] Preferably, the first alarm is a light alarm, which flashes a light to sound an alarm; or the first alarm is a sound alarm, which buzzes to sound an alarm; or the first alarm includes a light alarm and a sound alarm.

[0047] Preferably, the feed sensor 11 and the return sensor 13 are respectively arranged at the two ends of the second fixed frame 14 for sensing the second slider 17. When the second slider 17 drives the supporting frame 20 and the cement board to move forward for feeding, and moves the cement board to the front end position, the second slider 17 triggers the front feed sensor 11, so that the feed sensor 11 transmits a signal to the controller, and the controller controls the first linear displacement device and the cutting device 22 to stop working, and the controller controls the second linear displacement device 2 to drive the cement board to retreat backward to the starting position of feeding. When the second slider 17 drives the supporting frame 20 and the cement board to move backward and retreat so that the cement board moves to the rear starting position, the second slider 17 triggers the rear return sensor 13, so that the return sensor 13 transmits a signal to the controller, and the controller controls the second linear displacement device 2 to stop working, and the worker replaces the cement board moved to the starting position to prepare for the next feeding test.

[0048] Preferably, the feed sensor 11 and the return sensor 13 are proximity switches or micro switches or Hall switches.

[0049] In addition, the frame 1 is also provided with a second alarm and a detection module for detecting the current / voltage change of the cutting device 22. The second alarm and the detection module are both electrically connected to the controller. When the cutting device 22 burns or stops during the cutting test, the detection module detects the current / voltage change and transmits a signal to the controller. The controller controls the test equipment to stop, and the controller controls the second alarm to sound an alarm. Since the power supply current of the cutting device 22 changes when it burns or stops, in simple terms, it is a short circuit. The time when the cutting device 22 burns or stops can be accurately obtained by detecting the current / voltage of the cutting device 22, and a shutdown command can be accurately issued, so that the obtained data is more accurate. The detection module is an existing conventional module.

[0050] It is also possible to manually observe whether the cutting device 22 burns out or stops during the cutting test. A damping sensor can also be set on the first linear displacement device to determine whether the cutting device 22 burns out or stops by whether the movement of the first slider 9 is blocked during the test.

[0051] Preferably, the second alarm is a light alarm, which flashes a light to sound an alarm; or the second alarm is a sound alarm, which buzzes to sound an alarm; or the second alarm includes a light alarm and a sound alarm.

[0052] In addition, a timing module is provided on the frame 1, and the timing module is electrically connected to the controller. The timing module is used to record the time when the cutting device 22 is turned on and the cutting operation is performed. When the cutting device 22 burns in or stops during the test, the timing module stops timing, and the recorded time is used for comparison to understand the durability of the tested cutting device 22. The timing module is an existing conventional module.

[0053] Working principle of the test equipment: Step 1, place the cement board to be cut by the cutting device 22 on the support frame 20, and fix the cutting device 22 to be tested on the first slide block 9;

[0054] Step 2: Connect the cutting device 22 to be tested to the testing equipment through a power line, so that the testing equipment provides power to the cutting device 22;

[0055] Step 3, start the test equipment, and the cutting device 22 under test automatically starts up;

[0056] Step 4: the first slider 9 drives the cutting device 22 to move leftward, so that the cutting device 22 cuts the cement board to the left;

[0057] Step 5: When the cutting device 22 moves to the left to the first position, the first slider 9 triggers the sensor 10 on the left, and the sensor 10 transmits a signal to the controller, and the controller controls the first linear displacement device to stop working, so that the cutting device 22 stops at the first position. At the same time, the controller controls the second slider 17 to drive the support frame 20 and the cement board to move forward a set distance, so that the uncut cement board part moves forward to a position opposite to the cutting device 22;

[0058] Step 6: After the cement board moves forward by a set distance, the controller controls the first slider 9 to drive the cutting device 22 to run in the reverse direction, so that the cutting device 22 moves to the right to cut the cement board;

[0059] Step 7: When the cutting device 22 moves rightward to the second position, the first slider 9 triggers the sensor 10 on the right side, and the sensor 10 transmits a signal to the controller, and the controller controls the first linear displacement device to stop working, so that the cutting device 22 stops at the second position. At the same time, the controller controls the second slider 17 to drive the support frame 20 and the cement board to move forward a set distance, so that the uncut cement board part moves forward to a position opposite to the cutting device 22;

[0060] Step 8: After the cement board moves forward by a set distance, the controller controls the first slider 9 to drive the cutting device 22 to run in the reverse direction, so that the cutting device 22 moves to the left to cut the cement board;

[0061] Step nine, the testing device repeats the actions of the above steps four to eight until the cement board is driven by the second slider 17 to move forward to the end position, at which time the cement board has been completely cut by the cutting device 22, and the second slider 17 triggers the feed sensor 11, and the feed sensor 11 transmits a signal to the controller, and the controller controls the cutting device 22 and the first linear displacement device to stop working, and at the same time the controller controls the second slider 17 to drive the cement board to retreat backward;

[0062] Step 10: When the cement board retreats to the starting position, the second slider 17 triggers the material return sensor 13, and the material return sensor 13 transmits a signal to the controller, and the controller controls the second linear displacement device 2 to stop working, so that the cement board stops at the starting position, and the first alarm sounds an alarm to remind the replacement of the cement board;

[0063] Step eleven, after the cement board is replaced, the actions of the above steps four to ten are repeated to allow the cutting device 22 to continuously cut. When the detection module detects a change in the current / voltage of the cutting device 22, it is determined that the cutting device 22 is burned out or stopped. The detection module transmits a signal to the controller, and the controller controls the test equipment to shut down, and issues an alarm through the second alarm to indicate the end of the test.

[0064] Figure 1 As shown, in addition, a data display module is also provided on the frame 1, and the input end of the data display module is electrically connected to the output end of the controller. Preferably, the data display module is a control panel 4, and the data collected by the controller is displayed on the screen of the control panel 4, such as the current and voltage of the cutting device 22 and the time recorded by the timing module, so that information can be obtained more intuitively, and the test equipment can be set and controlled through the buttons on the control panel 4.

[0065] In addition, the controller includes a segmented speed setting submodule, which is used to set the speed of different segments when the first linear displacement device drives the cutting device 22 to reciprocate in a linear motion, simulating the speed inconsistency phenomenon during manual operation to achieve the closest test effect to reality. For example, the segmented speed setting submodule is used to set the first servo motor 5 of different segments to output different speeds when the cutting device 22 reciprocates in a linear motion. Controlling the motor speed through the controller is an existing structure, and reference can be made to the motor speed controller.

[0066] Figure 1 As shown, the above-mentioned controller and each module can be integrated in a control box 3.
