[0035] Example

[0036] like Figure 1-5 As shown, this embodiment provides a height detection mechanism, including: a base 1, a positioning device 2 arranged on the base 1, a detection device 3 arranged directly above the base 1, and a control console 4 for feeding back the height size of the workpiece to be detected. After the positioning device 2 moves the workpiece to the specified position, the detection device 3 starts working and feeds back the detection result to the control console 4. This process is simple to operate and easy to use, and can quickly and accurately detect the specific height of the workpiece to be detected, with high precision and time and labor saving, that is, no manual detection is required, which not only reduces the waste of manpower, but also ensures the accuracy of the detection result and high work efficiency. Moreover, the height detection mechanism can be preferably installed on an automated production line to detect large quantities of workpieces, thereby realizing large-scale production of workpieces and ensuring the yield rate.

[0037] Among them, the positioning device 2 includes: a limit component 21 arranged on one side of the base 1 and a positioning component 22 respectively arranged on two adjacent sides of the limit component 21. Preferably, the limit component 21 is arranged on the left side of the base 1, and the two positioning components 22 are respectively arranged on the upper and lower sides of the base 1, so as to limit and fix the workpiece to be inspected from three directions to avoid the workpiece from shifting during the inspection process, resulting in inaccurate inspection results or failure to detect, thereby ensuring the stability of the workpiece and further ensuring the accuracy of the inspection results.

[0038] At the same time, the limit assembly 21 includes: a first driving member 211 arranged under the base 1 and a limit plate 212 arranged at the output end of the first driving member 211, and the limit plate 212 passes through the base 1, and is powered by the first driving member 211 to drive the limit plate 212 to move up and down reciprocatingly. The initial state of the limit plate 212 is that its upper surface is flush with the upper surface of the positioning seat, which is convenient for removing the workpiece. When the workpiece needs to be inspected, the limit plate 212 moves up to block the movement of the workpiece. After the workpiece inspection is completed, the limit plate 212 begins to reset to the initial state, and the position of the limit plate 212 on the base 1 can be determined according to the external size of the workpiece, which plays a role in preliminary positioning.

[0039] In this embodiment, the positioning assembly 22 includes: a second driving member 221 arranged on the base 1 and a baffle 222 arranged at the output end of the second driving member 221. The second driving member 221 provides power to drive the baffle 222 to move back and forth. The baffle 222 is used to limit the position of the workpiece to avoid the workpiece from being offset, resulting in inaccurate detection results.

[0040] In this embodiment, the detection device 3 includes: a bracket 31 vertically arranged on the base 1, a third driving member 32 arranged on the bracket 31, a detection component 33 fixedly connected to the output end of the third driving member 32, and a sensor 34 arranged between the detection component 33 and the bracket 31, and the sensor 34 is connected to the console 4. The detection component 33 moves down and presses to detect the height of the workpiece. At this time, the sensor 34 starts to work and feeds back the signal to the console 4. The whole process does not require manual operation, avoiding errors caused by manual operation, and making the detection result more accurate and precise.

[0041] In this embodiment, the detection component 33 includes: a detection mold 331 adapted to the workpiece to be detected, a pressing piece 332 arranged above the detection mold 331, and an elastic piece 333 arranged between the detection mold 331 and the pressing piece 332. The pressing piece 332 can press the detection mold 331 down onto the workpiece under the action of the elastic piece 333, so that there is no gap between the detection mold 331 and the workpiece, which can effectively avoid the situation where the detection mold 331 is not fully in place due to the appearance of a gap between the detection mold 331 and the workpiece, resulting in inaccurate detection results. The elastic piece 333 can preferably be a spring, which can not only ensure elasticity but also can be quickly installed.

[0042] In this embodiment, the pressing member 332 is fixedly connected to the third driving member 32 by a connecting block 321. The connecting block 321 increases the force-bearing area of ​​the pressing member 332, which can ensure that the pressing member 332 does not shake during movement, making it more stable, thereby ensuring the stability of the detection mold 331 during movement, and preventing position deviation, thereby smoothly aligning the workpiece for detection operations. The pressing member 332 can avoid direct contact with the third driving member 32, reducing the wear of the pressing member 332, eliminating the need for frequent replacement, and extending its service life, thereby ensuring the service life of the detection mold 331.

[0043] In this embodiment, a pushing device 5 is provided on the opposite side of the positioning device 2, and the workpiece to be inspected is moved to the designated position on the base 1 by the pushing device, thereby reducing manual operation and making the position of the workpiece very accurate, avoiding position errors caused by manual placement, thereby ensuring the accuracy of the inspection result. When inspecting the workpiece, the pushing device 5 does not reset, and automatically resets after the inspection is completed, thereby further ensuring the stability of the workpiece.

[0044] In this embodiment, the pushing device 5 includes: a fourth driving member 51 arranged on the opposite side of the limiting assembly 21 and a push plate 52 arranged at the output end of the fourth driving member 51. The fourth driving member 51 provides power to drive the push plate 52 to move horizontally back and forth, which is simple to operate and easy to use.

[0045] Of course, the shapes of the push plate 52, the baffle plate 222 and the limit plate 212 are all compatible with the shape of the workpiece to be detected, that is, their shapes can be determined according to the actual shape of the workpiece. The workpiece of this embodiment is preferably cylindrical, then the limit plate 212 can be preferably straight or figure eight, and the baffle plate 222 and the push plate 52 can be preferably figure eight, so that the workpiece can be more stable and firm, and will not deviate, thereby ensuring the accuracy of the detection result.

[0046] In addition, the first driving member 211, the second driving member 221, the third driving member 32 and the fourth driving member 51 can all be preferably cylinder driven, because the cylinder is easy to control, very easy to adjust, fast in response, can ensure work efficiency, and the pressure level required by the cylinder drive is low, which can well ensure the safety of use. Its working medium is air, which will not pollute the environment and has low cost.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
