[0040] In order to solve the problem of low measurement accuracy and slow measurement speed in manual measurement of the deformation amount of the sliding table of the electric actuator in the prior art, the utility model embodiment provides an electric actuator sliding table deformation amount automatic measuring device, which uses the thrust mode of the electric actuator to generate a specified thrust on the sliding table of the electric actuator to be measured, detects the displacement of the sliding table through the sensors located on both sides of the sliding table, and determines the deformation amount of the sliding table based on the displacement of both sides of the sliding table. The measurement accuracy is high, the measurement speed is fast, and the degree of automation is high.
[0041] The utility model embodiment provides an electric actuator sliding table deformation amount automatic measuring device, the structure is as shown in Figure 1 、 Figure 2 、 Figure 3 As shown in the drawings, wherein, Figure 1 is the perspective structural schematic diagram of the device, Figure 2 is the front view of the device, Figure 3It is a side view of the device, specifically comprising:
[0042] The rack 1, the positioning assembly and the measuring assembly mounted on the rack 1;
[0043] The positioning assembly comprises a slide rail 201 and a baffle 202 fixed on the rack 1, and a mounting plate 203 arranged on the slide rail 201, the mounting plate 203 being used for placing the electric actuator 6 to be measured, and the baffle 202 being used for limiting the slide table 601 of the electric actuator 6 to be measured;
[0044] The measuring assembly comprises a mounting frame 301 perpendicular to the direction of the slide rail 201, a second electric actuator 302 horizontally fixed on the mounting frame 301, a first electric actuator 303 vertically fixed on the second electric actuator 302, and a sensor assembly arranged below the first electric actuator 303; the sensor assembly is used for detecting the displacement of the slide table 601 of the electric actuator 6 to be measured on both sides under the preset pushing force of the first electric actuator 303, as shown in Figure 4 It can be seen from the figure that the displacement sensors are respectively arranged on both sides of the slide table 601.
[0045] In the positioning assembly, the electric actuator 6 to be measured on the mounting plate 203 moves on the slide rail 201 towards the measuring assembly, and under the action of the baffle 202, the slide table 601 of the electric actuator 6 to be measured moves to the lower side of the measuring assembly to stop, so that the measuring assembly can measure the displacement of the slide table 601.
[0046] In the measuring assembly, under the action of the second electric actuator 302, the first electric actuator 303 is driven to move to one side above the slide table 601 of the electric actuator 6 to be measured to exert a preset pushing force, and then the sensor assembly detects the displacement of the slide table 601 under the pushing force. Alternatively, the first electric actuator 303 does not have a slide table. The first electric actuator 303 is fixed on the slide table of the second electric actuator 302 through a pin. The first electric actuator 303 uses a preset torque output mode to make the piston rod 3031 generate a specified force to exert a pushing force on the slide table.
[0047] The device further comprises a pneumatic cylinder 4 fixed on the baffle 202, a rubber block 5 arranged below the pneumatic cylinder 4, and the pneumatic cylinder 4 being used for pressing the electric actuator 6 to be measured downward when the slide table 601 of the electric actuator 6 to be measured is positioned below the first electric actuator 303; the rubber block 5 is used for buffering the force of the pneumatic cylinder 4, and reducing the friction and abrasion of the pneumatic cylinder 4 to the electric actuator 6 to be measured.
[0048] In some optional embodiments, the mounting plate 203 of the positioning assembly is provided with a mounting groove 2031 for mounting the electric actuator 6 to be measured. Optionally, the distance between the baffle 202 of the positioning assembly and the piston rod 3031 of the first electric actuator 303 of the measuring assembly is half the length of the slide table 601 of the electric actuator 6 to be measured, so that the slide table 601 of the electric actuator 6 to be measured is located directly below the first electric actuator 303, so that the positioning of the slide table 601 is more accurate and it is more convenient for the first electric actuator 303 to control the distance required when the first electric actuator 303 controls the slide table 601 to move to the side above the slide table 601 to apply force.
[0049] In some optional embodiments, the sensor assembly comprises displacement sensor mounting plates respectively fixed on both sides of the piston rod 3031 of the first electric actuator 303, and displacement sensors mounted on the displacement sensor mounting plates. Specifically, the displacement sensor mounting plates comprise a first displacement sensor mounting plate 3041 fixed on one side of the piston rod 3031 of the first electric actuator 303 and a second displacement sensor mounting plate 3042 fixed on the other side of the piston rod 3031. The displacement sensors comprise a first displacement sensor 3043 mounted on the first displacement sensor mounting plate 3041 and a second displacement sensor 3044 mounted on the second displacement sensor mounting plate 3042. The displacement sensors can be linear displacement sensors for detecting the displacement of the slide table 601 of the electric actuator 6 to be measured on both sides of the slide table after one side of the slide table is subjected to a predetermined pushing force.
[0050] The device further comprises a host computer for receiving the displacement of the slide table detected by the sensor assembly after the slide table 601 of the electric actuator 6 to be measured is subjected to a predetermined pushing force, and determining the deformation of the slide table based on the displacement of the slide table. Specifically, the principle of determining the deformation of the slide table based on the displacement of the slide table is as shown in FIG. 6. When one side of the slide table 601 of the electric actuator 6 to be measured is subjected to a predetermined pushing force, the side of the slide table subjected to the pushing force will produce a downward displacement, and the displacement sensor on this side will detect the amount of downward displacement. The other side of the slide table will produce an upward displacement, and the displacement sensor on this side will detect the amount of upward displacement. Then, the deformation of the slide table is the sum of the amount of downward displacement and the amount of upward displacement. Figure 5
[0051] The working principle of the electric actuator slide table deformation automatic measurement device is as follows:
[0052] In order to more clearly describe the movement process of the device, the movement direction of the slide rail 201 is defined as the y-axis direction, the moving track of the first electric actuator 303 on the slide table 601 of the to-be-tested electric actuator 6, that is, the direction from one side of the slide table 601 to the other side is defined as the x-axis direction, and the force direction of the first electric actuator 303 to the slide table 601 of the to-be-tested electric actuator 6 is defined as the z-axis direction.
[0053] 1) The to-be-tested electric actuator 6 is placed in the mounting groove 2031 of the mounting plate 203, and the to-be-tested electric actuator 6 moves on the slide rail 201 towards the measuring assembly, so that the slide table 601 of the to-be-tested electric actuator 6 contacts the baffle 202, at this time the slide table 601 is directly below the first electric actuator 303.
[0054] 2) Under the action of the second electric actuator 302, the first electric actuator 303 moves to above the edge of one side of the slide table 601 along the X-axis direction, the piston rod 3031 starts to move downward, contacts the slide table 601, and stops moving after reaching a specified force, the slide table 601 deforms due to the force, and the side of the slide table 601 subjected to the force moves downward, and the other side moves upward, as shown in Figure 5 The displacement amount A and the displacement amount B are detected by the linear displacement sensors on both sides of the slide table 601, and then the displacement amount data is transmitted to the upper computer. The upper computer determines the deformation amount of the slide table based on the obtained displacement amount. Similarly, the first electric actuator 303 is moved to above the edge of the other side of the slide table 601 along the X-axis, and the deformation amount of the slide table when a specified force is applied to the other side can be obtained.
[0055] 3) The first electric actuator 303 is reset, and the to-be-tested electric actuator 6 is pulled out.
[0056] The device of the embodiment of the utility model, through the accurate positioning to the slide table of the to-be-tested electric actuator, after positioning, the slide table of the to-be-tested electric actuator is clamped downward by the cylinder, then the first electric actuator is used to apply a specified force to the slide table of the to-be-tested electric actuator, and the displacement sensor is used to realize the automatic detection of the displacement amount of the slide table, then the deformation amount of the slide table is determined based on the displacement amount of the slide table, the automatic measurement of the deformation amount of the slide is realized, and the efficiency and accuracy of the factory detection are improved.
