DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides: a linear displacement sensor detection device, such as Figure 1-Figure 4 As shown, it includes a workbench 1, and two groups of positioning seats 5 are symmetrically installed on the left and right sides of the workbench 1. An electric push rod 6 is bolted to the upper part of the positioning seat 5 on one side of the workbench 1, and a motor 7 is bolted to the upper part of the positioning seat 5 on the other side of the workbench 1; a slide plate 9 is slidably installed inside the workbench 1, and a test baffle 12 is slidably installed on the upper part of the workbench 1, and the bottom end of the test baffle 12 is inserted into the limit seat 14 and movably installed.

[0023] Preferably, an inner groove 2 is opened on the upper surface of the workbench 1, and two groups of limit grooves 3 are symmetrically opened inside the inner groove 2. Two groups of slide grooves 4 are symmetrically opened on the upper end surface of the workbench 1. The inner groove 2 opened on the upper surface of the workbench 1 enables the slide plate 9 to be accommodated and slide inside the inner groove 2, so that the electric push rod 6 and the motor 7 can work better together to control the movement of the sensor position of the linear displacement sensor body 19, so as to better detect the working state of the sensor. The limit groove 3 opened inside the inner groove 2 cooperates with the rolling ball 11 at the bottom of the slide plate 9 to better limit the movement of the slide plate 9, so as to ensure the sensitivity of the sensor position movement, reduce the test error, and ensure the test accuracy.

[0024] Furthermore, a rotating sleeve rod 8 is installed at the output end of the motor 7. The center points of the electric push rod 6 and the rotating sleeve rod 8 are at the same height. The motor 7 controls the rotating sleeve rod 8 to rotate, and the rotating sleeve rod 8 drives the axis of the linear displacement sensor body 19 to rotate, thereby controlling the sensor position to move, and completing the test of the sensitivity of the linear displacement sensor body 19. At the same time, since the center heights of the electric push rod 6 and the rotating sleeve rod 8 are consistent, the electric push rod 6 can stably push the linear displacement sensor body 19 and the rotating sleeve rod 8 to complete the connection, so that the rotating sleeve rod 8 can better drive the linear displacement sensor body 19 to move.

[0025] Furthermore, an anti-skid pad 10 is embedded and installed on the upper surface of the skateboard 9, and several groups of rolling balls 11 are symmetrically and rotatably embedded and installed on the bottom of the skateboard 9. Each group of rolling balls 11 rotates inside the limit groove 3, and the lower surface of the skateboard 9 does not fit the inner wall of the inner groove 2. The linear displacement sensor body 19 is placed on the upper surface of the skateboard 9 and is anti-skid limited by the anti-skid pad 10. Since the two ends of the linear displacement sensor body 19 are respectively limited by the electric push rod 6 and the rotating sleeve rod 8, the skateboard 9 as a whole is used as a limiter for the sensor without adding an additional limit structure. The skateboard 9 does not fit the inner wall of the inner groove 2, so that the movement of the skateboard 9 is only through the rolling balls 11, which greatly reduces the friction of the skateboard 9, makes the skateboard 9 more sensitive to the movement of the linear displacement sensor body 19, and makes the test result more accurate.

[0026] It is worth mentioning that a group of punctuation marks 13 are respectively installed in the middle of both sides of the test baffle 12, and a group of positioning bolts 15 are threadedly installed on the same side of each group of limit seats 14. The ends of the positioning bolts 15 are movably pressed against the surface of the test baffle 12. The punctuation marks 13 on both sides of the test baffle 12 can better cooperate with the sensor to complete the test. After the bottom end of the test baffle 12 is inserted into the limit seat 14, it is locked and fixed by the positioning bolts 15 to change the use position of the test baffle 12, which can better make the punctuation marks 13 correspond to the sensor position, and the test of the linear displacement sensor body 19 is completed by moving the test baffle 12.

[0027] Specifically, a limit frame 16 is fixedly installed on the outside of the limit seat 14, and the limit frame 16 is slidably installed in close contact with the workbench 1. A ball bearing is rotatably embedded and installed on the lower surface of the limit frame 16 corresponding to the position of the slide groove 4. The limit frame 16 installed on the outside of the limit seat 14 is used to limit the use position of the limit seat 14, thereby ensuring the stability of the test baffle 12 during the movement and reducing the test error.

[0028] In addition, a drive box 17 is fixedly installed at the bottom end of the limit frame 16, and a moving wheel 18 is key-connected to the output end of the drive box 17. The outer arc surface of the moving wheel 18 is rotatably installed in contact with the outer surface of the workbench 1. The electric driver inside the drive box 17 controls the moving wheel 18 to rotate in contact with the surface of the workbench 1, thereby completing the movement of the test baffle 12. Under the premise of not changing the position of the linear displacement sensor body 19, the sensitive test of the linear displacement sensor body 19 is completed, thereby further improving the detection quality.

[0029] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
