Technical field
The present invention relates to a kind of clamping device, be specifically related to a kind of two ends floating clamping device.
Background technology
In the machining manufacturing industry, the locating clip clamper plays very important effect, and it guarantees that the relative lathe of workpiece, cutter etc. are in correct position all the time, guarantees uniformity and the crudy of workpiece processing.
The location of workpiece and fastening, the selection of its stress point and stress surface has determined to locate and fastening effect, traditional clamping device, more selection one or more surfaces, one or more realize that to workpiece the location clamps as stress point or stress surface, seldom adopt the method that stress surface is combined with stress point, and this method that links work at selected spots with that in entire areas realizes that to the workpiece of some special shapes it clamps effect and is even more important.
Although existing clamping device can satisfy the clamping demand of workpiece to a certain extent, but in the actual use procedure, the inventor finds that it still exists following some shortcomings: 1, the selection of stress surface or stress point is too single, easily cause the displacement of workpiece in process, be difficult to realize the accuracy of location; 2, multiple spot clamping device, traditional generally is to utilize the plural serial stage lever to realize that the multiple spot multidigit clamps, and employed mechanism is very lengthy and tedious, and structure is very not compact; 3, classify from the power resources of clamping device, generally can be divided into hydraulic pressure, pneumatic and manual three classes, multiple spot or multidigit jig generally all need larger clamping force, generally, people are often forced must to adopt hydraulic clamp, pollutes because hydraulic oil volatilizees and leaks surrounding enviroment such as causing air, ground but hydraulic drive is as easy as rolling off a log; Pneumatic Transmission also has the distinct disadvantage that himself can't overcome, because the as easy as rolling off a log leakage of gas, cause the operating pressure of pneumatic actuator system can not the very high easy like this waste that causes resource, use cost increases and continues to exert pressure to clamp makes whole cargo handling process complicated, the weak effect of loading and unloading inconvenience and self-locking.
Summary of the invention
The technical problem to be solved in the present invention provides the two ends floating clamping device of a kind of registration, simple in structure, easy to use and energy-conserving and environment-protective.
In order to solve the problems of the technologies described above, the invention provides a kind of two ends floating clamping device, include matrix, gear as drive unit, rotating shaft and handle, be provided with the guide post of tooth bar, its tooth bar and the engagement of described gear, rocking arm as transmission device, a left side that is used for the clamping work pieces upper surface, right jaw, a left side that is used for the supporting workpiece lower surface, the right support post, wherein, described rotating shaft and described gear are the integral type structure, the end of this structure shaft is taper and passes the set conical through-hole that matches with it of matrix, described handle is fixedly connected with the tapering point of rotating shaft, described guide post places matrix middle part perpendicular in the set through hole of shaft axis direction, cooperate to realize its elevating movement with described gear, the bottom driving end of guide post is fixedly connected with the middle part of described rocking arm, rotating shaft; rocking arm and guide post be the three-dimensional coordinate structure axially; described rocking arm two ends and a described left side; the bottom drive end of right support post is fixedly connected with; a described left side; the right support post all pass matrix set with the through hole guide post axially parallel; a described left side; right jaw one end is articulated in matrix, the left side of the other end and supporting workpiece lower surface; the right support post cooperates up and down realization to the clamping at workpiece two ends.
Turning handle, the rotating shaft driven gear rotates, gear cooperates with the guide post that is provided with tooth bar, realize the elevating movement of guide post, order about simultaneously rocking arm and drive left and right support column and do corresponding elevating movement, when guide post is in when upper, at this moment; rocking arm and left and right support column all are in upper, left and right support column contacts the support force that makes progress to workpiece one with workpiece, and this support force cooperates the purpose that realizes clamping work pieces with left and right jaw; When guide post is in when the next, this moment, rocking arm and left and right support column all were in the nextly, and left and right support column is away from workpiece, the support force that makes progress to workpiece disappears thereupon, and at this moment, outwarding winding is articulated in left and right jaw on the matrix, workpiece is released, can take out caught workpiece.
Adopt the two ends floating clamping device of technique scheme to have the following advantages: 1, owing to the mode that has adopted the point of application to combine with force surface to the workpiece two ends, avoided the poor problem of the single stressed steadiness that causes, therefore the setting accuracy to workpiece is high; 2, owing to adopted the rocking arm two ends to drive simultaneously left and right support column to move up and down, avoided arranging lengthy and tedious, so the present invention it is simple in structure; 3, owing to adopted manual operation to replace traditional hydraulic pressure or the power source mechanism such as pneumatic, so it is simple to operate easy to use, simultaneously also energy-conserving and environment-protective.
As preferred version, may cause wearing and tearing and improve the accuracy that workpiece is located its top when considering left and right support column and workpiece Long Term Contact, the top driven end of described left and right support column all arranges spacer pin.
As preferred version, consider that rotating shaft can exceed restriction in the process of rotating, make wheel and rack engagement degree inadequate, described rotating shaft relative with its tapering point and an end that stretches out matrix are equipped with back-up ring.
As preferred version, consider that workpiece can produce more chip in process, and chip falls into matrix inside and can cause wheel and rack normally not mesh, thereby impact clamps effect, the top of the through hole that described guide post passes is provided with cover plate.
