[0002] Bushings are used outside mechanical parts to achieve sealing, wear protection and other functions. They refer to rings that act as gaskets. Some bushings have keyways, and the bushings are installed by keying the keyways of the bushings and the keyways of the assembly parts.

[0003] After the bushing is produced, it is necessary to test whether the bushing is qualified, and the test items include coaxiality, shaft hole diameter, keyway size, etc. At present, when testing the keyway of the bushing, some manufacturers conduct the test through operators, specifically by measuring the length or width parameters with a vernier caliper. This kind of test is time-consuming, labor-intensive and inefficient. Summary of the invention

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] It should be noted that in the description of the present invention, the directions or positional relationships indicated by the terms "front", "rear", "left", "right", "up", "down", "inside", "outside", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention rather than requiring the present invention to be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. The terms "front", "rear", "left", "right", "up", and "down" used in the description of the present invention refer to the directions in the accompanying drawings, and the terms "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0031] like Figures 1 to 5 As shown, a bushing keyway detection device includes a detection mechanism 4 and a rotatably arranged connecting seat 3, the connecting seat 3 includes a shell 35, a fixed seat 31 connected in the shell 35, a positioning rod 32 is connected to the center of the top surface of the fixed seat 31, and a connected groove body 33 is provided in the axial direction of the fixed seat 31 and the positioning rod 32; the detection mechanism 4 includes a detection plate mechanism 42, a mounting seat 45 and a driving reset mechanism, the mounting seat 45 is fixed on the shell 35, the detection plate mechanism 42 includes a slider 421 slidably connected to the mounting seat 45, a detection plate 422 is connected to one side of the slider 421, and the detection plate 422 is slidably connected in the groove body 33; the driving reset mechanism is used to drive the slider 421 to move up and down, so that the detection plate 422 moves up and down in the groove body 33.

[0032] The slider in the driving reset mechanism is driven to descend, driving the detection plate to descend, and the detection mechanism as a whole is driven to rotate by rotating the connecting seat. When it rotates to the keyway of the bushing, the slider rises to insert the detection plate into the keyway to complete the detection. If the connecting seat rotates one circle and the detection plate is not inserted into the keyway, the keyway of the bushing is unqualified. The present application improves the efficiency of keyway detection by setting a rotatable connecting seat and a liftable detection plate.

[0033] Specifically, Figure 1As shown, in one embodiment of the present application, a base 1 is provided, and the shape of the base 1 can be disc-shaped, and a through hole or a screw hole is provided on the base 1 to facilitate fixing the device as a whole. A rotating cylinder 2 is connected to the base 1, and a connecting seat 3 is connected to the output end of the rotating cylinder 2. By providing the rotating cylinder 2, the rotation effect of the connecting seat 3 can be ensured.

[0034] In the present application, the rotation angle of the rotary cylinder 2 is set to 360° each time, that is, the rotary cylinder 2 stops after rotating one circle, and the rotary cylinder 2 rotates one circle again when rotating next time. This design is to cooperate with the detection of the keyway on the bushing.

[0035] Furthermore, when performing bushing inspection, the bushing can be grasped by a robot arm and inserted into the outer periphery of the positioning rod 32. The connecting seat 3 is controlled to rotate one circle to drive the inspection plate mechanism 42 to rotate one circle. If the keyway on the bushing 5 is qualified, the inspection plate 422 will be inserted into the keyway during one rotation. If the keyway on the bushing is unqualified, the inspection plate 422 will not be inserted into the keyway after one rotation.

[0036] In a further embodiment of the present application, a detection sensor is provided in the positioning rod 32, and the detection sensor can be an existing photoelectric sensor, and its purpose is to determine whether the detection plate 422 is inserted into the keyway. Specifically, the detection sensor is arranged at the top of the slot 33 of the positioning rod 32, and when the detection plate 422 moves upward and is inserted into the keyway of the bushing 5, the detection sensor will detect the existence of the detection plate 422.

[0037] In a further embodiment, the detection sensor is connected to the rotary cylinder 2 by signal. When the detection sensor detects that the detection plate 422 is inserted into the keyway of the bushing 5, a control signal is sent to control the rotary cylinder 2 to stop rotating.

[0038] In some embodiments, in order to ensure that the bushing is easily inserted into the positioning rod 32, the top end of the positioning rod 32 is designed to be a conical structure.

[0039] In the present application, the width of the portion of the detection plate 422 located outside the slot body 33 is the same as the width of the keyway of the bushing 5, and the length of the portion of the detection plate 422 located outside the slot body 33 is the same as the length of the keyway of the bushing 5. With this design, the bushing detection effect can be ensured, and the keyway detection is achieved by inserting the detection plate 422 into the keyway of the bushing.

[0040] In one embodiment, the drive reset mechanism includes a push rod 41 and a guide block 423 connected to a slider 421 and located on the opposite side of the detection plate 422. The bottom surface of the guide block 423 is connected to the mounting block 43 on the housing 35 through an elastic member. Further, the elastic member is a spring 424.

[0041] The driving reset mechanism further includes a telescopic cylinder 44 . The telescopic cylinder 44 is connected to the housing 35 via a connecting frame 34 . The output end of the telescopic cylinder 44 is connected to the push rod 41 .

[0042] During operation, the output end of the telescopic cylinder 44 is telescoped to squeeze the guide block 423, and the guide block 423 drives the slider 421 to descend, thereby driving the detection plate 422 to descend. When the guide block 423 descends, it compresses the spring 424. When the telescopic cylinder 44 is reset, the guide block 423 drives the slider 421 to rise under the action of the spring 424, thereby driving the detection plate 422 to rise.

[0043] In some embodiments, in order to ensure the effect of the push rod 41 pushing the guide block 423 to move, the extension direction of the push rod 41 is set to be perpendicular to the sliding direction of the slider 421. The connecting surface of the guide block 423 and the push rod 41 is also set to be an inclined surface.

[0044] In a certain embodiment, a limit block 425 is further provided. The limit block 425 is connected to the top of the side of the slider 421 and can be used to limit the downward movement distance of the slider 421 .

[0045] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
