Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
To make the purpose of this utility model, technical scheme and advantage clearer, clear and definite, develop simultaneously implementation referring to the drawings
The utility model is further described example.
Refering to Fig. 1, the utility model provides a kind of processing unit (plant) with position-limit mechanism, wherein, including base 40, it is described
Fuselage 10 is provided with base 40, fuselage 10, which is connected with main spindle box 20, the main spindle box 20, to be provided with drive processing head
The internal spindle bar 30 of lower motion, the internal spindle bar 30 is connected with journey stop gear, internal spindle bar 30 and stroke limit
Position mechanism is connected with electric control gear respectively, in addition to is arranged at being carried out firmly to it when processing head is down moved on base 40
Spacing fixation position-limit mechanism, internal spindle bar 30 is moved downwardly to after setting height, triggers journey stop gear, electric control gear
Control internal spindle bar is moved until triggering journey stop gear again upwards.
Further, journey stop gear includes the first electronic switch 60, the second electronic switch 61, the tune of screw rod 62, first
The adjusting nut 64 of nut 63 and second is saved, the first adjusting nut 63 and the second adjusting nut 64 coordinate with screw rod 62, internal spindle
Bar 30 drives screw rod 62, the first adjusting nut 63 and the second adjusting nut 64 to move up and down, and screw rod 62 is down moved until second
Electric control gear control internal spindle bar 30 changes direction and up moved when adjusting nut 64 touches the second electronic switch 61, it is to avoid
Processing head continues down motion and causes mismachining tolerance, improves machining accuracy, and internal spindle bar 30 changes direction and up transported
It is dynamic to stop up to the first adjusting nut 63 touches the electric control gear of the first electronic switch 60 control processing head.
If only relying on journey stop gear, because the first adjusting nut 63 and the second adjusting nut 64 and electronic switch are tactile
Touch and there is the sensitive time, and internal spindle bar is down moved there is also inertia, so existing necessarily from touching to stop
Time difference, the spacing of zero error can not be carried out to workpiece completely this results in journey stop gear.
Therefore, the utility model is also provided with hard spacing fixation position-limit mechanism, and fixed position-limit mechanism includes being connected to and added
Locating piece 50 and the positioning screw 51 being connected on base 40 on work head, internal spindle bar 30 is down moved during processing workpiece

The spacing mode of hardness, improves spacing accuracy and precision, it is to avoid the product hole portion processed is deep mixed, or even goes out
Existing scrap products.
Further, the first electronic switch 60 includes the first contact 601, and the second electronic switch 61 includes the second contact 611,
Screw rod 62 is down moved until the second adjusting nut 64 touches the electric control gear control of the second contact 611 of the second electronic switch 61
Internal spindle bar 30 changes direction and up moved, until the first adjusting nut 63 touches the first contact of the first electronic switch 60
601 electric control gears control processing head stops.
Two threaded portions are provided with distance, the screw rod 62 in order to which moving down for head of processing can be adjusted, described first adjusts
The section adjusting nut 64 of nut 63 and second is connected with two threaded portions respectively, by adjusting the second adjusting nut 64 in threaded portion
Position be that adjustable processing machine head moves down distance, for example, the second adjusting nut 64 is up twisted, the He of the second adjusting nut 64
Second contact 611 is touched later, and processing head moves down more distances, on the contrary, the second adjusting nut 64 is down twisted, second
The contact 611 of adjusting nut 64 and second is touched earlier, and processing head moves down less distance, similarly, and regulation first adjusts spiral shell
The position of mother 63 also can adjust processing head and move up distance.
Further, the distance between the first contact 601 and the second contact 611 are more than the first adjusting nut 63 and second and adjusted
Save the distance between nut 64.
The utility model is by providing a kind of processing unit (plant) with position-limit mechanism, there is provided journey stop gear, screw rod
Down motion is until the second contact electric control gear control internal spindle bar that the second adjusting nut touches the second electronic switch changes
Change direction and up move, until the first adjusting nut touches the first contact electric control gear control processing machine of the first electronic switch
Head stops, and prevents that the stroke that processing head is down advanced is excessive, causes mismachining tolerance；Meanwhile, it is also provided with progress hard spacing
Fixed position-limit mechanism, head is processed when locating piece and positioning screw are touched can not continue down, and the utility model enters to workpiece
Row double limitation is protected, spacing precision is high, stability is high, it is to avoid product the phenomenon that processing scraps occurs and occurred.
It should be appreciated that application of the present utility model is not limited to above-mentioned citing, those of ordinary skill in the art are come
Say, can according to the above description be improved or converted, all these modifications and variations should all belong to the appended power of the utility model
