Abstract
Provided is a positioning device for a workbench. The upper surface of a machine tool horizontal carriage is a swallowtail boss. The cylinder body portion of a grip oil cylinder is arranged in the boss of the horizontal carriage. A piston rod extends out of a cabinet. The front end of the piston rod is provided with a T-shaped block. The T-shaped block can slide in a T-shaped groove of the workbench. The workbench is pushed so that the T-shaped groove on the bottom surface is installed in the T-shaped block. When the grip oil cylinder clamps, the T-shaped block arranged on the front end of the piston rod moves downward to clamp the T-shaped groove, that is, the workbench is clamped downward. At the moment, the slopes on two sides of the workbench completely contact with the slopes on two sides of the horizontal carriage, so the workbench is fixed without moving on left-right directions. The front end of the horizontal carriage is provided with a spacing switch. When the workbench moves to touch the spacing switch, a signal is generated to the control system of the machine tool, and the workbench stops moving forward, and the workbench is fixed on front-rear directions. Thus, the workbench is fixed without moving on six directions of front, back, left, right, up, and down, and an objective of positioning is achieved.
Description
Technical field
The present invention relates to the positioner of a kind of workbench, specifically the pinpoint device of a kind of workbench realizing lathe.
Background technology
Development along with machine industry, in order to realize the cutting way multifunction of lathe, require Installing machine tool and use multiple adnexa, adnexa is installed on the table, the purpose of switch adjunct is reached by switch operating platform, need just to carry out machining with base location then adnexa fast and safely after workbench switching, need for this to provide a set of reliable positioner.nullThe positioner that current workbench uses，Clamping cylinder is installed in the base，Piston rod extends outside the base，The front end of piston rod is provided with cylindrical piece，The periphery of cylindrical piece is provided with an arc groove，A circle steel ball it is arranged with in groove，Steel ball slightly protrudes periphery，The bottom surface of workbench cavity is provided with a groove，Its groove two sides are respectively arranged with protruding equilateral triangle corner angle，The wedge angle of triangle is relative，Before workbench and base are about to position，Article two, the hypotenuse of triangle corner angle catches steel ball，The hypotenuse of three arms of angle contacts with steel ball，Now have been filled with hydraulic oil in hydraulic jack，Piston is in raised configuration，The cylindrical piece of piston rod and front end thereof is similarly in raised configuration，Steel ball is in free state in arc groove，When the hydraulic oil in oil cylinder flows out，After oil cylinder loosens，The piston rod of its front end declines，Pull cylindrical piece that piston rod front end installs and steel ball to decline simultaneously，Steel ball moves along hypotenuse until cylindrical piece is by steel ball and inclined-plane tension，Now workbench is positioned.This structure is high to the requirement on machining accuracy of part, not easily processes, and steel ball anti-pressure ability is poor, broken, and therefore this positioner is easily damaged, poor stability, and the life-span is short.
Summary of the invention
It is an object of the invention to, for the deficiencies in the prior art, provide the positioner of a kind of workbench for lathe, to ensure to realize between workbench energy and cross slide positioning accurately and reliably.
The present invention solves that the upper surface of the technical scheme is that lathe cross slide of its technical problem is swallow-tail form boss, the left and right sides of boss are inclined-plane, and namely the bottom surface of workbench is the dovetail face cooperated with the upper surface of cross slide.The cylinder body of clamping cylinder is placed in the boss of cross slide, piston rod stretches out outside casing, piston rod front end is provided with T-shaped piece, going to the bottom of workbench is provided with T-slot, the T-shaped piece of T-slot gone to the bottom with workbench of piston rod front end matches, T-shaped piece can be moved in the T-slot of workbench, clamping cylinder is connected with hydraulic system, open hydraulic system and can control the lifting of clamping cylinder, clamping cylinder declines, the piston rod of its front end drives the T-shaped piece of tension adnexa workbench that declines, workbench is pressed on cross slide, adnexa workbench is clamped, on, lower direction is maintained static, the bottom surface of workbench and the upper surface of cross slide are dovetail face, left and right sides are that inclined-plane coordinates, when the clamped block of workbench is clamped on cross slide, both inclined-planes match, the left and right sides is maintained static.The end of cross slide is provided with limit switch, limit switch is connected with machine tool control system, after workbench moves forward to and touches limit switch, it is signaled to the control system of lathe, workbench stops moving forward, former and later two directions can position, and such front, back, left, right, up, down six direction is all positioned, and reaches the purpose of table positions.
The positioner of the workbench described in the present invention, parts are few, simple in construction, functional reliability high, deficiency and the defect of table positions mode in prior art can be made up, comprehensive reliable location can be carried out, it is possible to require the occasion of location suitable in various lathes.
Accompanying drawing explanation
Fig. 1 is the positioning device structure figure of the workbench described in the present invention.
Detailed description of the invention
With reference to accompanying drawing, will be described in detail specific embodiments of the present invention.In FIG, the upper surface of lathe cross slide 5 is dove-tail form boss, the two sides of boss are inclined-plane 6, both sides are each provided with two row clamping oil cylinders around, the cylinder part of clamping cylinder 3 is arranged in the boss of cross slide 5, piston portion stretches out outside casing and its head is provided with T-shaped piece 2, and T-shaped piece 2 T-slot gone to the bottom with workbench 1 matches, it is possible to move in T-slot.When workbench 1 is moved forward by promotion, T-shaped piece 2 of piston rod front end is moved in the T-slot that workbench 1 is gone to the bottom, after workbench 1 touches the limit switch 4 being arranged on cross slide 5 end (front end or rear end), limit switch 4 sends the signal of " putting in place " to machine tool numerical control system, workbench 1 is made to stop mobile, now fore-and-aft direction is positioned, after workbench stopping is mobile, clamping cylinder 2 starts action, piston rod moves down, drive its head T-shaped piece 2 moves until straining downwardly together, workbench 1 above-below direction is clamped, it is that dove-tail form inclined-plane coordinates because the left and right directions of workbench 1 is with cross slide 5 upper surface, therefore left and right both direction is maintained static, so, before, after, left, right four direction is all maintained static, reach the purpose of table positions.
The positioner of the workbench described in the present invention, the cylinder body of its clamping cylinder 3 can also be placed in adnexa workbench 1, and the piston rod front end of its clamping cylinder 3 is provided with T-shaped piece 2, becomes to be slidably matched in the T-shaped piece 2 described T-slot being arranged on cross slide 1.
