Abstract
The utility model discloses an accurate positioning device of the moveable workbench of a large- and medium- scale hydraulic press, which comprises a moveable workbench and a lower cross beam, wherein, circular holes are formed on the lower cross beam and the moveable workbench respectively; a positioning dowel with a lug boss is mounted on the lower plane surface of the moveable workbench; a positioning sleeve with a concave platform is mounted on the upper plain surface of the lower cross beam; and the positioning dowel is inserted in to the positioning sleeve when in operation. When the workbench is needed to be moved out, the moveable workbench is uplifted under the action of a lifting device to allow the positioning dowel be separated from or higher than the positioning sleeve; after an electrically controlled device shifts out the moveable workbench and replaces moulds, the moveable workbench is moved in the lower cross beam by the electrically controlled device and stops until the lower cross beam hit a hitting block; and the workbench is allowed to be in contact with the lower cross beam, and the positioning dowel is inserted into the positioning sleeve through a falling device. The positioning device adopts the positioning dowel to position a device, thereby ensuring that the moveable workbench can obtain a higher repeatedly positioning accuracy, and guaranteeing the product quality of thin plate stretching pieces.
Description
Technical field:
The utility model relates to the movable workbench of hydraulic press positioner, more specifically says so to be applied in travelling table accurate positioning device on the big-and-middle-sized hydraulic press.
Background technology:
At present known in big-and-middle-sized movable workbench of hydraulic press, what take is non-detachable locating pin structure, and this structure in use for some time, and is relatively more difficult when needing to change.
Summary of the invention:
The utility model is for avoiding above-mentioned existing in prior technology weak point, be provided at the accurate dowel device that detachably is convenient for changing in the big-and-middle-sized hydraulic press, changing alignment pin conveniently.
The technical scheme that the utility model technical solution problem is adopted is:
Big-and-middle-sized movable workbench of hydraulic press accurate positioning device, include travelling table, sill, it is characterized in that: the alignment pin that has boss is installed on the travelling table lower plane, in the middle of installing on the plane on the sill is the positioning sleeve of concave station, and the concave station in the middle of boss and the positioning sleeve is the coupling that matches.
Described large hydraulic press travelling table accurate positioning device is characterized in that alignment pin and positioning sleeve all install by screw.
Described large hydraulic press travelling table accurate positioning device is characterized in that alignment pin, positioning sleeve are installed on respectively on travelling table lower plane, the sill in the counterbore on the plane.
Described large hydraulic press travelling table accurate positioning device is characterized in that being between boss and the concave station matched in clearance.
During operate as normal, alignment pin is to insert positioning sleeve.When needing workbench to shift out, travelling table rises under the effect of lifting device, make the alignment pin disengaging and exceed positioning sleeve, shift out more mold exchange of sill by the automatically controlled workbench that makes, after replacing finishes, move into sill by the automatically controlled travelling table that makes again, after limit switch slows down, run into collision block and stop.The workbench falling device makes plane contact on workbench lower plane and the sill, alignment pin inserts positioning sleeve, because pin is very little with the fit clearance of cover, so this structure can make travelling table reach very high repetitive positioning accuracy, to guarantee the product quality of thin plate tensioning member.
Alignment pin of the present utility model and positioning sleeve are installed in travelling table and sill with trip bolt, can change the alignment pin and the positioning sleeve of damage easily and fast.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The utility model adopts dismountable accurate dowel device that is convenient for changing.Its great advantage is exactly to change the positioner of damage easily and fast, and this structure processing is simple, easy to operate.
Description of drawings:
The big-and-middle-sized movable workbench of hydraulic press accurate positioning device of Fig. 1 structure chart.
The big-and-middle-sized movable workbench of hydraulic press accurate positioning device of Fig. 2 (a) and (b) layout drawing.
Number in the figure: 1 travelling table, 2 trip bolts, 3 alignment pins, 4 sills, 5 trip bolts, 6 positioning sleeves, 7 accurate positioning device, 8 travelling tables shift out guide rail, 9, travelling table shifts out electric control gear.
Below in conjunction with accompanying drawing, and the utility model is described in further detail to pass through the specific embodiment.
The specific embodiment:
Referring to accompanying drawing 1,2.
Big-and-middle-sized movable workbench of hydraulic press accurate positioning device, include travelling table 1, sill 4, on the travelling table lower plane circular hole is arranged, with trip bolt 2 alignment pin 3 that has boss is installed in the circular hole, circular hole is also arranged on the plane on the sill 4, and installing middle with trip bolt 5 in the circular hole is the positioning sleeve 6 of concave station, and the concave station in the middle of boss and the positioning sleeve 6 is a matched in clearance.
During operate as normal, alignment pin 3 is to insert positioning sleeve 6.When needing travelling table to shift out, travelling table is risen under the effect of lifting device, make alignment pin 3 disengagings and exceed positioning sleeve 6, shifting out electric control gear by travelling table makes workbench shift out sill to enter more mold exchange of guide rail, after replacing finishes, make travelling table move into sill by electric control gear again, after the contact limit switch slows down, run into collision block and stop.
The workbench falling device makes plane contact on workbench lower plane and the sill, alignment pin inserts positioning sleeve, because pin is very little with the fit clearance of cover, so this structure can make travelling table reach very high repetitive positioning accuracy, to guarantee the product quality of thin plate tensioning member.
Alignment pin of the present utility model and positioning sleeve are installed in travelling table and sill with trip bolt, can change the alignment pin and the positioning sleeve of damage easily and fast.
Claims (4)
1, big-and-middle-sized movable workbench of hydraulic press accurate positioning device, include travelling table, sill, it is characterized in that: the alignment pin that has boss is installed on the travelling table lower plane, in the middle of installing on the plane on the sill is the positioning sleeve of concave station, and the concave station in the middle of boss and the positioning sleeve is the coupling that matches.
2, large hydraulic press travelling table accurate positioning device according to claim 1 is characterized in that alignment pin and positioning sleeve all install by screw.
3, large hydraulic press travelling table accurate positioning device according to claim 1 is characterized in that alignment pin, positioning sleeve are installed on respectively on travelling table lower plane, the sill in the counterbore on the plane.
