[0032] The utility model is described in detail below with reference to the accompanying drawings.
[0033] like Figure 1-3As shown, a mechanical structure capable of automatically adjusting height includes a working plate 1, a height adjustment platform 45 is arranged below the working plate 1, the working plate 1 is equipped with a first driving seat 12 capable of longitudinal elastic movement, the first driving seat 12 is equipped with a second driving seat 26 capable of longitudinal movement, the second driving seat 26 is equipped with a processing head 4; the first driving seat 12 is equipped with a lower detection block 31, the second driving seat 26 is equipped with an upper detection block 34 coaxially and longitudinally aligned with the lower detection block 31, and the upper detection block 34 and the lower detection block 31 are elastically contacted and signal-connected.
[0034] When the first drive seat 12 descends, the second drive seat 26 descends at the same time, and the processing head 4 installed on the second drive seat 26 will move longitudinally and approach the height platform 45 at the same time. The upper detection block 34 and the lower detection block 31 are separated from each other at the moment after the processing head 4 contacts the height platform 45, and the connection between the upper detection block 34 and the lower detection block 31 is disconnected, and a disconnection signal is sent; when a different processing head 4 is replaced, it is necessary to contact the height platform 45 again by referring to the same method to determine the height of the new processing head 4; there is no need to re-debug, and the portability efficiency is greatly improved.
[0035] Preferably, the upper detection block 34 and the lower detection block 31 are respectively conductive metal blocks. When the upper detection block 34 and the lower detection block 31 are in contact, they are in conductive contact and can output a power-on signal. When the upper detection block 34 and the lower detection block 31 are separated, they can output a power-off signal.
[0036] Specifically, the working plate 1 is installed with a top fixing member 23, the first driving seat 12 is installed with a bottom fixing member 24, and a tension spring 25 is installed between the top fixing member 23 and the bottom fixing member 24. The elastic driving force of the tension spring 25 can drive the lower detection block 31 installed on the first driving seat 12 to maintain elastic contact with the upper detection block 34 installed on the second driving seat 26.
[0037] At the moment after the processing head 4 contacts the platform 45, the first drive seat 12 will continue to press down. At this time, the lower detection block 31 installed on the first drive seat 12 is separated from the upper detection block 34 installed on the second drive seat 26, and the connection between the upper detection block 34 and the lower detection block 31 is disconnected, and a disconnection signal is sent; then, under the elastic drive of the tension spring 25, the first drive seat 12 will rebound, so that the upper detection block 34 and the lower detection block 31 maintain elastic contact.
[0038] The working plate 1 is provided with a longitudinal driving member 11 for driving the first driving seat 12 to move longitudinally. The longitudinal driving member 11 includes a driving shaft 13 that can rotate laterally. The driving shaft 13 is installed with a motor connecting block 14. The motor connecting block 14 can make a circular swinging motion. The first driving seat 12 is provided with a movable connecting groove 18 that is movably connected to the motor connecting block 14. When the driving shaft 13 rotates, the motor connecting block 14 installed on the driving shaft 13 swings accordingly and makes a circular trajectory motion. It is connected to the first driving seat 12 through the movable connecting groove 18, so that the first driving seat 12 can move up and down accordingly.
[0039] Furthermore, the motor connecting block 14 is provided with an eccentric hole 15, a rolling bearing 16 is installed in the eccentric hole 15, a top connecting seat 17 is installed on the top of the first driving seat 12, and the top connecting seat 17 is laterally provided with the movable connecting groove 18; the driving shaft 13 is rotated by the drive of the servo motor 19, and the rolling bearing 16 installed in the eccentric hole 15 will move in a circular trajectory, and the movable connecting groove 18 formed on the top connecting seat 17 can allow the rolling bearing 16 to move, thereby maintaining the longitudinal movement stability of the first driving seat 12.
[0040] Preferably, the working plate 1 is provided with a first guide rail 2 for the longitudinal movement of the first driving seat 12, the first guide rail 2 includes a longitudinally arranged first guide rail 21, the first guide rail 21 is slidably mounted with a first sliding seat 22, the first sliding seat 22 is connected to the first driving seat 12, when the first driving seat 12 moves longitudinally, the first sliding seat 22 connected to the first driving seat 12 moves longitudinally along the first guide rail 21, thereby ensuring the longitudinal movement stability of the first driving seat 12.
[0041] The first drive seat 12 is provided with a first mounting structure 3 for mounting a lower detection block 31, the first mounting structure 3 includes an L-shaped block 32, the lower detection block 31 is longitudinally penetrated in the transverse part of the L-shaped block 32, and a limiting rod 35 is installed in the longitudinal part of the L-shaped block 32; the second drive seat 26 is provided with a second mounting structure 30 for mounting an upper detection block 34, the second mounting structure 30 includes a mounting seat 33, the upper detection block 34 is installed at the bottom of the mounting seat 33, the lower detection block 31 is fixedly installed on the transverse part of the L-shaped block 32, and the upper detection block 34 is installed at the bottom of the mounting seat 33, and can be fine-tuned to ensure the coaxiality of the upper detection block 34 and the lower detection block 31.
[0042] In addition, the mounting seat 33 is installed with a limit seat 37, and the limit seat 37 is formed with a limit hole 38 coaxially aligned with the limit rod 35, and the limit rod 35 is embedded with a limit ring 36 that cooperates with the limit hole 38 stopper; when the processing head 4 is in contact with the high platform 45, the lower detection block 31 is separated from the upper detection block 34, and the limit rod 35 will slide axially along the limit hole 38 of the limit seat 37. When the distance between the lower detection block 31 and the upper detection block 34 is too large, the limit ring 36 of the limit rod 35 will cooperate with the limit hole 38 stopper to prevent the lower detection block 31 from being separated from the upper detection block 34 by too large a distance.
[0043] The first drive seat 12 is longitudinally arranged with multiple second guide rails 27, and the back of the second drive seat 26 is formed with a guide sliding groove 28 that slides with the second guide rail 27. When the first drive seat 12 moves longitudinally, the second drive seat 26 will continue to descend at an instant after the processing head 4 contacts the height platform 45, and the second drive seat 26 will move longitudinally along the second guide rail 27 through the guide sliding groove 28 to ensure the longitudinal movement stability of the second drive seat 26.
[0044] The second driving seat 26 is installed with a transversely arranged processing seat 41, and the processing seat 41 is formed with a mounting hole 42. The processing head 4 includes a syringe 43 and a Luer connector 44 installed at the bottom of the syringe 43.
