[0019] The utility model provides a flatness detection device.

[0020] See also Figure 1In one embodiment of the present invention, the flatness detection device includes a base plate 10, a pressing assembly 20 and a feeler gauge assembly 30. The pressing assembly 20 is arranged on the base plate 10 and is used to press the workpiece 40 to be tested onto the base plate 10; the feeler gauge assembly 30 is rotatably arranged on the base plate 10. When the pressing assembly 20 presses the workpiece 40 to be tested onto the base plate 10, the feeler gauge assembly 30 is rotated so that the feeler gauge assembly 30 passes between the base plate 10 and the workpiece 40.

[0021] The surface of the bottom plate 10 is a standard plane and is used to place a test object 40. In this embodiment, the test object is the lower bracket of the atomizer, which has at least three threaded posts 41. When the lower bracket is placed on the bottom plate 10, the bottom surface of the threaded posts 41 is in contact with the surface of the bottom plate 10.

[0022] One end of the clamping assembly 20 is fixed to the edge of the base plate 10, and the lower bracket is placed in the middle of the base plate 10 to ensure stable placement of the lower bracket. The other end of the clamping assembly 20 is rotated toward the middle of the base plate 10 until it abuts against the lower bracket, thereby pressing the lower bracket between the clamping assembly 20 and the base plate 10.

[0023] After the lower bracket is tightened, under normal conditions, the bottom surface of the threaded post 41 will completely mate with the surface of the base plate 10, leaving no gap. In this embodiment, to verify the function of the lower bracket, the feeler gauge assembly 30 is rotated until it is positioned between the lower bracket and the base plate 10. It will be appreciated that since there is no gap between the lower bracket and the base plate 10, the feeler gauge assembly 30 cannot be rotated between the test piece 40 and the base plate 10. Therefore, if the feeler gauge assembly 30 cannot be rotated between the test piece 40 and the base plate 10, the lower bracket is functioning properly. Otherwise, the lower bracket is abnormal.

[0024] It should be noted that before testing, the position of the feeler gauge assembly 30 is adjusted in advance according to the shape and size of the lower bracket, so that when the lower bracket is placed on the base plate 10, the threaded column 41 is exactly within the rotation path range of the feeler gauge assembly 30, ensuring that the feeler gauge assembly 30 can perform measurements stably.

[0025] The present invention utilizes the clamping assembly 20 to compress and secure the bracket to the base plate 10. The feeler gauge assembly 30 is rotated between the base plate 10 and the bracket to determine whether the bracket's flatness meets the required standards. This simple and effective testing process improves testing efficiency to meet mass production requirements.

[0026] In one embodiment, the pressing assembly 20 includes a pressing rod 21 and a rotating member 22 , wherein one end of the pressing rod 21 is connected to the rotating member 22 , and the other end of the pressing rod 21 rotates toward one side of the base plate 10 to press the test piece 40 onto the base plate 10 .

[0027] The rotating member 22 is fixed to the edge of the bottom plate 10, and one end of the pressure rod 21 is hinged to the rotating member 22, so that the other end of the pressure rod 21 rotates around the hinge position, and the rotation axis of the pressure rod 21 is parallel to the surface of the bottom plate 10. Figure 1 and Figure 2 The rotating member 22 is fixed to the bottom of the base plate 10. When the workpiece 40 needs to be inspected, the pressure rod 21 is controlled to rotate clockwise so that the pressure rod 21 is pressed against the workpiece 40. When the inspection of the workpiece 40 is completed, the pressure rod 21 is controlled to rotate counterclockwise so that the pressure rod 21 is released from the workpiece 40.

[0028] The rotating member 22 specifically comprises a mounting plate 221 and two connecting plates 222. The mounting plate 221 is arranged parallel to the base plate 10 and fixed to the base plate 10 on both sides by screws. The two connecting plates 222 are arranged perpendicular to the base plate 10 and parallel to each other. This creates a mounting gap between the two connecting plates 222, into which the pressure rod 21 extends. The pin 23 passes through the left connecting plate 222, the pressure rod 21, and the right connecting plate 222 in sequence, allowing the pressure rod 21 to rotate about the pin 23.

[0029] In this embodiment, the mounting plate 221 and the two connecting plates 222 are integrally formed to improve the connection strength of the rotating member 22 and enhance the stability and reliability of the pressure rod 21 during testing.

[0030] In one embodiment, the pressure rod 21 is provided with an escape groove 211, and the shape of the escape groove 211 is adapted to the shape of the test piece 40. Figure 1 and Figure 2 The piece to be tested 40 is rod-shaped, and the position where it abuts the pressure rod 21 is the side wall of the cylinder. The avoidance groove 211 on the pressure rod 21 is correspondingly set to be an arc shape. When the pressure rod 21 is pressed tightly on the lower bracket, the lower bracket is accommodated in the avoidance groove 211, thereby achieving a positioning effect for the lower bracket and preventing the position of the lower bracket from being offset after being pressed.

[0031] It should be noted that a plurality of pressure rods 21 with avoidance grooves 211 of different shapes can be configured, and the pressure rod 21 and the rotating part 22 are detachably connected, so that when dealing with test pieces 40 of different models and shapes, the pressure rod 21 with the avoidance groove 211 corresponding to its shape can be replaced, thereby improving the compatibility of the equipment.

[0032] In one embodiment, the feeler gauge assembly 30 includes a standard ruler 31 and a hinge 32. The standard ruler 31 is set on the base plate 10, and the surface of the standard ruler 31 is in contact with the surface of the base plate 10; the hinge 32 is set at one end of the standard ruler 31 so that the other end of the standard ruler 31 rotates around the hinge 32 as the center.

[0033] The standard ruler 31 is a thickness gauge, and its thickness can be adjusted according to the production requirements of the test piece 40. After the test piece 40 is pressed against the base plate 10, the standard ruler 31 is rotated so that it passes between the lower bracket threaded column 41 and the base plate 10. If the test piece 40 is of acceptable quality, the standard ruler 31 will not be able to enter between the test piece 40 and the base plate 10. If the test piece 40 is of abnormal quality, the standard ruler 31 can be rotated between the test piece 40 and the base plate 10. The inspector can determine whether the test piece 40 is qualified by observing whether the standard ruler 31 can enter between the test piece 40 and the base plate 10.

[0034] Please refer to Figure 3 In this embodiment, the test piece 40 is provided with three threaded posts 41. Correspondingly, three test areas are provided on the base plate 10, with each threaded post 41 corresponding to a test area. A feeler gauge assembly 30 is positioned within each test area, meaning each feeler gauge assembly 30 is positioned at the edge of a threaded post 41. The standard ruler 31 has a certain length; ensuring that the threaded post 41 is within the corresponding rotational path of the standard ruler 31 is sufficient.

[0035] The standard ruler 31 is flat and is placed on the surface of the base plate 10. One end of the standard ruler 31 is hinged by a screw, so that the standard ruler 31 can rotate around the screw connection position.

[0036] In one embodiment, the base plate 10 is provided with a plurality of threaded holes 11, which are used to connect with threaded posts 41 on the test piece 40. The number of threaded holes 11 is the same as the number of threaded posts 41, and the positions are arranged in a one-to-one correspondence. During testing, each threaded post 41 is associated with a threaded hole 11. Screws are screwed into the threaded holes 11 and threaded posts 41 to achieve positioning of the test piece 40.

[0037] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
