Description
Technical field
This utility model relates to a kind of liftable integrated positioning mechanism of hydraulic control.
Background technology
Traditional vertical processing machine tool is in processing hole or in some open grade face, usually first on special plane, bore one or several hole, then go on machining center with this some holes be positioning datum come coarse-fine boring other endoporus and open a grade face, simultaneously, work in-process in the heart, realizes the location of workpiece frequently with latch or steady pin. Therefore, the processing of a workpiece needs multiple devices to complete, and the multiple clamping of workpiece is consuming time longer, and production efficiency is low; Meanwhile, workpiece adopts the error that latch positions relatively big, the serious wear of alignment pin, and the vibration adding man-hour easily causes workpiece size deviation, even produces waste product etc.
Summary of the invention
For above-mentioned prior art Problems existing, this utility model provides a kind of liftable integrated positioning mechanism of hydraulic control, by the alternately lifting between the multiple alignment pin of HYDRAULIC CONTROL SYSTEM, it is possible to achieve the quick location of diverse location endoporus on workpiece. The integrated positioning mechanism that multiple alignment pins are constituted, it is possible to the workpiece that aperture is different is positioned and is processed, its positioning precision is high, and working (machining) efficiency is high, can reduce workpiece vibration in the course of processing or deformation simultaneously.
To achieve these goals, the technical solution adopted in the utility model is: a kind of liftable integrated positioning mechanism of hydraulic control, it is characterized in that base is fixed on workbench by workbench, base, described base is provided with at least two alignment pin,
Alignment pin all includes guide, soket head cap screw, piston rod, hydraulic cylinder, elastic seal ring, screw and hydraulic cylinder, and guide is fixed on the piston rod of hydraulic cylinder, and elastic seal ring is embedded in piston rod, and hydraulic cylinder is fixing with hydraulic cylinder to be connected.
Described alignment pin is the angular alignment pin of circular cone or diamond positioning pin.
Being provided with three alignment pins on described base, respectively circular cone angular alignment pin A, the angular alignment pin B of circular cone and diamond positioning pin, diamond positioning pin coordinates location with the angular alignment pin B of circular cone angular alignment pin A and circular cone respectively.
Guide adopts soket head cap screw to be connected with piston rod.
Hydraulic cylinder and hydraulic cylinder adopt screw to be fastenedly connected.
This utility model solves workpiece on tradition machining tool and to process consuming time longer on multiple devices, the shortcomings such as efficiency is low, and error is bigger. Detent mechanism is to be respectively fixedly connected with on piston rod by two or more positioning pin sets, after clamping workpiece completes, by the alternately lifting between the multiple alignment pin of HYDRAULIC CONTROL SYSTEM, it is possible to achieve the quick location of diverse location endoporus on workpiece. The integrated positioning mechanism that multiple alignment pins are constituted, it is possible to the workpiece that aperture is different is positioned and is processed. This detent mechanism simple in construction, positioning precision is high, and working (machining) efficiency is high, can reduce workpiece vibration in the course of processing or deformation simultaneously.

Detailed description of the invention
Below in conjunction with accompanying drawing 1, the utility model is described in further detail.
As Figure 1-3, a kind of liftable integrated positioning mechanism of hydraulic control described in the utility model includes workbench 1, base 5, the angular alignment pin A3 of circular cone, the angular alignment pin B4 of circular cone, diamond positioning pin 2, three alignment pins by including guide 6, soket head cap screw 7, piston rod 8, hydraulic cylinder 9, elastic seal ring 10, screw 11 and hydraulic cylinder 12 etc. form. Wherein, base 5 is fixed on workbench 1, the angular alignment pin A3 of circular cone, the angular alignment pin B4 of circular cone, diamond positioning pin 2 is each attached on base 5, guide 6 is fixed on the piston rod 8 of hydraulic cylinder 9, and elastic seal ring 10 is embedded in piston rod 8, and hydraulic cylinder 9 and hydraulic cylinder 12 adopt screw to be fastenedly connected. Guide 6 adopts soket head cap screw to be connected with piston rod 8, and the outside dimension of guide 6 can be adjusted according to the size in hole, location. Can fixing at least 2 alignment pins on base 5, their position can adjust according to the shape of workpiece, and diamond positioning pin 2 coordinates location with circular cone angular alignment pin A3 and alignment pin B4 respectively, it is possible to the workpiece of two kinds of different pore sizes is processed.
For the angular alignment pin A3 of the circular cone in Fig. 1, the boss two ends of hydraulic jack 9 have two apertures respectively in fig. 2, after hydraulic oil enters hydraulic jack 9 from the oil duct of right hole under the control of hydraulic system, it is full of bottom oil pocket, piston rod 10 is promoted to move up under pressure, after guide 6 is raised to the endoporus of workpiece, it is possible to achieve being quickly accurately positioned workpiece, and then other hole or face on processing work, when hole machined in needs are to this location, the diamond positioning pin 2 in Fig. 1 can be first allowed to rise, after completing the location to workpiece, again through hydraulic control system, the oil pressure made in Fig. 2 in left hole is higher, now, hydraulic oil will enter hydraulic jack 9 from the oil duct of left hole and be full of top oil pocket, and then promote piston rod 10 to move down, now, the location of workpiece completes by diamond positioning pin 2, the precision positioned in the course of processing for guarantee workpiece and seriality, when this integrated positioning mechanism can guarantee that work pieces process, workpiece is positioned by the alignment pin that there is at least one rise all the time, so, before diamond positioning pin rises, circular cone angular alignment pin A and alignment pin B all can not decline.
