Description
Technical field
The present invention relates to a kind of work piece holder.
Background technology
Along with the develop rapidly of modern industry, the mode of traditional artificial work has been difficult to the needs meeting modernization large-scale production, therefore, the use of automation equipment is got more and more, reason is the action such as fixing, processing, transfer that these automation equipments can complete all kinds of workpiece fast, wherein the fixing link of workpiece is even more important, if workpiece is fixing not firm, it will inevitably produce when bearing cutting force in process and rock, so very easily cause mismachining tolerance, therefore, these automation equipments needing can the fixture of firm fixation workpiece.
In addition, on firm fixing basis, the axis of workpiece, especially cylindrical work axis must with horizontal plane or parallel, can process accurately workpiece like this, but, existing workpiece fixed jig, complete but can not detect workpiece after workpiece is fixed axis whether with horizontal plane or parallel, so very easily cause larger mismachining tolerance.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of work piece holder can guaranteeing machining accuracy.
For solving the problems of the technologies described above, the invention provides a kind of work piece holder, comprising pedestal, described pedestal has the workpiece slot matched with workpiece end, in described workpiece slot, interval is provided with the first fore-set, the second fore-set and the 3rd fore-set;
The end face that described first fore-set, the second fore-set and the 3rd fore-set contact with workpiece is inwardly formed porose along its axis;
Be provided with flexible member in described hole, the top of described flexible member is connected with push rod, and described push rod can extend to the outside in described hole by described flexible member;
The bottom interval in each described hole be provided with positive electrode and negative electrode, the bottom of described push rod is provided with conducting block, can make described positive electrode and negative electrode conducting time in described push rod retraction hole by conducting block;
Described positive electrode and negative electrode and power supply and bulb pass through wired in series.
Described flexible member is helical spring.
The end face that described first fore-set contacts with workpiece is provided with rubber layer.
The end face that described second fore-set contacts with workpiece is provided with rubber layer.
The end face that described 3rd fore-set contacts with workpiece is provided with rubber layer.
The end face that described push rod contacts with workpiece is provided with rubber layer.
Compared with prior art, beneficial effect of the present invention is: because the present invention is after place work piece, when axis and the horizontal plane of workpiece, workpiece is in normal place, each push rod is stressed identical, push rod is pressed on the inside in hole completely, conducting block contacts with positive electrode and negative electrode, make circuit turn-on, bulb is lit, and when workpiece tilts, namely there is the angle of a non-90 degree between the axis of workpiece and horizontal plane, at this moment the stressed difference of each push rod, length in retraction inlet hole is not identical yet, therefore have some or two conducting blocks to contact with negative electrode with positive electrode, circuit is in open-circuit condition, bulb cannot be lit, after person to be operated finds this phenomenon, workpiece will be adjusted, thus avoid unnecessary mismachining tolerance, therefore the present invention can guarantee machining accuracy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is schematic diagram of the present invention.
In figure: pedestal 2, workpiece slot 4, the first fore-set 6, second fore-set the 8, three fore-set 9, hole 10, flexible member 12, push rod 14, positive electrode 16, negative electrode 18, conducting block 20.
Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly understand, below in conjunction with embodiment and accompanying drawing, the present invention is described in further details.At this, exemplary embodiment of the present invention and illustrating for explaining the present invention, but not as a limitation of the invention.
Shown in Figure 1, a kind of work piece holder of the present invention, comprise pedestal 2, the center of this pedestal 2 is provided with the workpiece slot 4 matched with workpiece end, in workpiece slot 4, interval is provided with the first fore-set 6, second fore-set 8 and the 3rd fore-set 9, the distribution in equilateral triangle of this first fore-set 6, second fore-set 8 and the 3rd fore-set 9, and the end face that contacts with workpiece of each first fore-set 6, second fore-set 8 and the 3rd fore-set 9 inwardly forms porose 10 along its axis; Be provided with preferably helical spring flexible member 12 in hole 10, the top of this flexible member 12 is connected with push rod 14, and push rod 14 can extend to the outside in hole 10 by flexible member 12; The bottom interval in each hole 10 be provided with positive electrode 16 and negative electrode 18, the bottom of push rod 14 is provided with conducting block 20 simultaneously, can positive electrode 16 and negative electrode 18 conducting by conducting block 20 when push rod 14 is retracted in hole 10; Positive electrode 16 and negative electrode 18 pass through wired in series with power supply and bulb.Designing principle of the present invention based on said structure is: in workpiece slot during non-place work piece, push rod 14 stretches out hole 10 under the effect of flexible member 12, conducting block 20 bottom push rod 14 does not contact with negative electrode 18 with spaced positive electrode 16, circuit is as described in Figure 2 in open-circuit condition bulb and is not lit, after place work piece, when axis and the horizontal plane of workpiece, workpiece is in normal place, each push rod 14 is stressed identical, push rod 14 is pressed on the inside in hole 10 completely, conducting block 20 contacts with positive electrode 16 and negative electrode 18 circuit turn-on made as shown in Figure 2, bulb is lit, and when workpiece tilts, namely there is the angle of a non-90 degree between the axis of workpiece and horizontal plane, at this moment the stressed difference of each push rod 14, length in retraction inlet hole 10 is not identical yet, therefore have some or two conducting blocks 20 to contact with negative electrode 18 with positive electrode 16, namely circuit is as shown in Figure 2 in open-circuit condition, bulb cannot be lit, after person to be operated finds this phenomenon, workpiece will be adjusted, thus avoid unnecessary mismachining tolerance, therefore the present invention can guarantee machining accuracy.
