Abstract
The utility model is that a kind of sclerometer adds off-load lifting bi-directional drive mechanism, comprise frame (1) and be arranged on the lifting shaft (3) in frame (1), one side of frame (1) is provided with motor (2), and a side of described lifting shaft (3) offers bar shaped tooth (4); The motor shaft of described motor (2) is connected with the gear (5) being meshed with described bar shaped tooth (4).By motor driven gear rotating, drive tooth bar and lifting shaft lifting, by the unidirectional drive of cam mechanism, change into bi-directional drive.Structure is compacter, and lifting shaft lifting transfer process is more steady, has not only improved the accuracy of hardness detection and the stability of rotation degree of Displaying Meter pointer, and has obviously reduced equipment work noise.
Description
Technical field
The utility model relates to a kind of sclerometer and adds off-load lift drive mechanism.
Background technology
Existing sclerometer adds that off-load lift drive mechanism comprises motor and by motor-driven cam mechanism, cam mechanism single direction rotation drives lifting shaft lifting, when lifting shaft arrives the flex point at peak place, the moment that namely lifting shaft falls after rise from peak, add unloading mechanism and tend to occur moment impact, the accuracy that hardness detects can be affected on the one hand, the shake of Displaying Meter pointer can be caused on the other hand.
Utility model content
The utility model aims to provide a kind of sclerometer and adds off-load lifting bi-directional drive mechanism, by change, adds off-load lifting type of drive, realizes the two-way smooth drive to lifting shaft.
The technical solution of the utility model is as follows:
Sclerometer adds an off-load lifting bi-directional drive mechanism, comprises frame and is arranged on the lifting shaft in frame, and a side of frame is provided with motor, it is characterized in that: a side of described lifting shaft offers bar shaped tooth; The motor shaft of described motor is connected with the gear being meshed with described bar shaped tooth.
On lifting shaft, be installed with optoelectronic switch baffle plate; At two diverse locations up and down of frame, be installed with respectively one and coordinate the optoelectronic switch that limits lifting shaft bound position with described optoelectronic switch baffle plate.
The utlity model has following characteristics: by motor driven gear rotating, drive tooth bar and lifting shaft lifting, by the unidirectional drive of cam mechanism, change into bi-directional drive.The utility model structure is compacter, and lifting shaft lifting transfer process is more steady, has not only improved the accuracy of hardness detection and the stability of rotation degree of Displaying Meter pointer, and has obviously reduced equipment work noise.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model (one), in order to show one-piece construction of the present utility model and principle of work.
Fig. 2 is structural representation of the present utility model (two), in order to show lifting shaft stroke positioning mechanism of the present utility model.
embodiment
Below in conjunction with drawings and Examples, further illustrate the utility model.
As shown in Figure 1, the utility model comprises frame 1 and is arranged on the lifting shaft 3 in frame 1 by orienting sleeve 6, and a side of frame 1 is provided with motor 2.
One side of described lifting shaft 3 offers bar shaped tooth 4 makes lifting shaft simultaneously as tooth bar.The motor shaft of described motor 2 is connected with the gear 5 being meshed with described bar shaped tooth 4.Described gear 5 is arranged in frame 1 by bearing.Motor 1 rotating, moves axially by pinion and rack bi-directional drive lifting shaft 3, realizes the elevating movement that sclerometer adds off-load unit.
As Fig. 2, on lifting shaft 3, be installed with optoelectronic switch baffle plate 7, the root of this optoelectronic switch baffle plate 7 is positioned at the opposite side of bar shaped tooth 4.And at two diverse locations up and down of frame 1, be installed with respectively one and coordinate the optoelectronic switch 8 that limits lifting shaft bound position with described optoelectronic switch baffle plate 7.In actual fabrication, optoelectronic switch 8 is provided with cannelure, and in a side of cannelure, optocoupler is installed, and optoelectronic switch baffle plate 7 makes progress or runs down to while setting bound position and runs in upper and lower cannelure and block optocoupler or lower optocoupler.When the optocoupler of optoelectronic switch 8 is blocked, send at once signal control motor 2 and change rotation direction.
Claims (2)
