Abstract
An automatic centering mechanism for electro-magnet rack and pinion comprises an upper V-shaped block and a lower V-shaped block with openings arranged correspondingly; a permanent magnet is arrangedat the bottom of the lower V-shaped block; a fixed electro-magnet is arranged correspondingly beneath the permanent magnet; the upper V-shaped block is connected with the lower V-shaped block in transmission way, and the moving directions of both are opposite; a guide bar is arranged on the lower V-shaped block; a driving rack is arranged along the moving direction on the guide bar; and a driven pinion is arranged on the upper V-shaped block in the moving direction, and a gear is engaged between the driving rack and the driven pinion. The utility model not only enables the work piece to be quickly mounted, but also can ensure the inner hole axial line of the work piece with the same axle with the rotating center of the main axle, so as to ensure the precision of the processed work piece. Moreover, the utility model has the advantages of high centering precision, quick, convenient work piece assembly and disassembly, reduced producing auxiliary conditions and improved producing efficiency; in addition, by adopting the electro-magnet rack and pinion structure, the mechanism is provided with certain functions of energy saving and environmental protection, and reduces the manufacturingcost.
Description
Technical field
The utility model relates to a kind of electromagnet rack-and-pinion self-centering unit.
Background technology
At present, processing round buss shape workpiece on the vertical boring mill, the endoporus bore hole of round buss class part generally adopts seam seat 11 location (seeing accompanying drawing 1), then by end face hold-down mechanism workpiece pressing 12.Workpiece for a kind of model, because the seam size of seam positioning seat is fixed, and the cylindrical of workpiece 12 is because the machining accuracy influence of last process, certain margin of tolerance is arranged, so be not of uniform size, when the cylindrical of workpiece 12 is worked into going up in limited time of workpiece predetermined tolerance, because gap A is little, workpiece 12 is not easy to put in the seam, if workpiece 12 processing are when the lower limit of workpiece predetermined tolerance, at this moment interporal lacuna A is big in workpiece 12 cylindricals and the seam, workpiece 12 puts in easily, but cause the interior axially bored line and the main shaft 13 pivot disalignments of work piece 12 easily,, thereby processed workpiece off-centre (endoporus axiality to foreign round is overproof) of coming out occurs as the B place among Fig. 1.
The utility model content
The utility model purpose is to provide a kind of electromagnet rack-and-pinion self-centering unit, can the Fast Installation workpiece, can guarantee that again the interior axially bored line of workpiece is coaxial with the main axis rotation center.
To achieve these goals, the utility model adopts following technical scheme: electromagnet rack-and-pinion self-centering unit, comprise last vee-block and following vee-block that opening is oppositely arranged, the bottom of following vee-block is provided with permanent magnet, the below correspondence of permanent magnet is provided with fixing electromagnet, last vee-block be in transmission connection with following vee-block by transmission connection piece and the direction of motion opposite.
Described vee-block down is provided with guide rod, and guide rod is provided with the active tooth bar along the direction of motion, and last vee-block is provided with the driven tooth bar along the direction of motion, and initiatively engagement is provided with gear between tooth bar and the driven tooth bar.
The utility model can the Fast Installation workpiece, can guarantee that again the interior axially bored line of workpiece is coaxial with the main axis rotation center, thereby guarantees the precision of the workpiece that processes, and centering precision height, workpiece loading and unloading are quick and convenient, reduce the production subsidiary conditions, enhance productivity; This mechanism adopts the electromagnet gear ﹠ rack structure in addition, has certain environmental protection and energy saving, has reduced production cost.
Description of drawings
Fig. 1 is the prior art constructions schematic diagram;
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
Embodiment: electromagnet rack-and-pinion self-centering unit as shown in Figure 2, comprise last vee-block 5 and following vee-block 4 that opening is oppositely arranged, workpiece 9 is arranged between vee-block 5 and the following vee-block 4, the bottom of following vee-block 4 is provided with permanent magnet 2, the below correspondence of permanent magnet 2 is provided with fixing electromagnet 1, last vee-block 5 be in transmission connection with following vee-block 4 by transmission connection piece and the direction of motion opposite.In the present embodiment, following vee-block 4 is provided with guide rod 3, and guide rod 3 is provided with the active tooth bar 6 along the direction of motion, and last vee-block 5 is provided with the driven tooth bar 8 along the direction of motion, and initiatively engagement is provided with gear 7 between tooth bar 6 and the driven tooth bar 8.
When the utility model uses, only need be placed on workpiece 9 on the flat board of location, in that vee-block 4 and last vee-block 5 are under promoting to motion down, workpiece is adjusted centering automatically.
The course of work is as follows: during original state, not energising of electromagnet 1, when electromagnet 1 feeds left-handed electric current, electromagnet 1 produces magnetic force, this moment the N utmost point of electromagnet 1 and the N pole-face opposite of permanent magnet 2, because polarity is identical, repel mutually, electromagnet 1 is fixed, permanent magnet 2 is forced to move inwards, permanent magnet 2 drives vee-block 4 down simultaneously, guide rod 3, initiatively tooth bar 6 travels forward, initiatively motion driven gear 7 rotations of tooth bar 6, gear 7 rotations drive driven tooth bar 8 motions again, driven tooth bar 8 promotes to go up vee-block 5 and moves inwards, vee-block 4 and last vee-block 5 motion inwards synchronously simultaneously down in this motion process, workpiece 9 is positioned, after workpiece 9 machines, electromagnet 1 feeds the dextrorotation electric current, electromagnet 1 produces magnetic force, this moment the S utmost point of electromagnet 1 and the N pole-face opposite of permanent magnet 2, because polarity is opposite, attract each other, electromagnet 1 is fixed, and permanent magnet 2 is forced outwardly motion, permanent magnet 2 drives vee-block 4 down simultaneously, guide rod 3, initiatively tooth bar 6 moves backward, initiatively motion driven gear 7 rotations of tooth bar 6, gear 7 rotations drive driven tooth bar 8 motions again, and driven tooth bar 8 promotes to go up vee-block 5 and outwards moves, vee-block 4 and last vee-block 5 outwards motion synchronously simultaneously down in this motion process, workpiece 9 is released.
