The specific embodiment
Below in conjunction with accompanying drawing, a specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention is not subjected to the restriction of the specific embodiment.
As shown in Figure 1 to Figure 3, adjustable auxiliary support apparatus for the workpiece blank face of the present invention, the auxiliary support bar 2 and the inserted link 7 that comprise clamp base 1, be perpendicular to one another and arrange, offer mutual perforation and vertical through hole on the clamp base 1 respectively, two through holes are respectively applied to the dovetail groove 71 of ccontaining auxiliary support bar 2 and inserted link 7 one ends.Dovetail groove 71 is located at the position that the end (among Fig. 1 left side) of inserted link 7 contacts with auxiliary support bar 2, and the inclination angle of dovetail groove bottom surface and horizontal plane is 8 ° ± 15 ', as shown in Figure 3.Auxiliary support bar 2 is dovetail structure 21 with the contact site of dovetail groove 71, and this dovetail structure 21 can be slided relatively with dovetail groove 71 adaptive connections and both.Certainly, dovetail groove herein also can adopt the tip chute of other form, and by the effect of tip chute, the movement of the horizontal direction of inserted link 7 can be converted into the movement on the vertical direction of auxiliary support bar; When auxiliary support bar 2 moves to the Support Position that needs in vertical direction, inserted link 7 can be locked in a certain particular location in the horizontal direction by the self-locking device that is positioned on the inserted link, thus the upright position of locking auxiliary support bar 2.
Below self-locking device is described in detail: this self-locking device comprises that the buting iron 4 of fixedlying connected with clamp base (adopts bolt 5 fixing in the embodiment of the invention, certainly also can adopt other fixedly connected mode), buting iron 4 is established the buting iron through hole in the corresponding position of inserted link, inserted link 7 is located in the buting iron through hole in dovetail groove 71 relative sides (being right side among Fig. 1), first nut, 8, the first nuts 8 that inserted link 7 outsides (being buting iron right side among Fig. 1), protrusion buting iron 4 one ends are established for fine setting are threaded with inserted link 7 employings; Inserted link inboard (be among Fig. 1 buting iron left side) suit one spring 9, spring 9 right-hand members are connected to second nut, 11, the second nuts of buting iron left side, spring 9 left ends establishing for the regulating spring compression stress 11 and are threaded with inserted link 7 employings.When avoiding rotating second nut 11 spring 9 follow rotation, between second nut 11 and spring 9, establish packing ring 10.
For ease of auxiliary support bar and inserted link dovetail groove are installed, be respectively equipped with in the mutual perforation on aforementioned clamp base and the vertical through hole for first pilot bushing 3 that auxiliary support bar is installed and for second pilot bushing 12 that the inserted link dovetail groove is installed.
Move for ease of the right direction of inserted link 7 along continuous straight runs in Fig. 1, establish handle 6 in the outermost end (being right-hand end among Fig. 1) that inserted link 7 protrudes buting iron one end, handle 6 adopts with inserted link 7 and is threaded.
Describe the course of work and the operation principle of the adjustable auxiliary support apparatus of the present invention below in detail:
The aiding support bar contacts with workpiece blank face (not shown) and is used for supporting this workpiece blank face, is connected with inserted link 7 by the dovetail groove horizontal by 8 ° of oblique angles.The effect of spring 9 is that inserted link 7 is resetted fast.Second nut 11 is used for adjusting spring force, and packing ring 10 is used for preventing that spring from following the nut rotation.Buting iron 4 is used for the other end, while block first nut 8 of restraining spring.By rotating first nut, 8 fine-tuning inserted links 7 position in the horizontal direction, thereby adjust the vertical direction position of aiding support bar 2 indirectly.Pulling handle 6 can make inserted link 7 fast moving in the horizontal direction, also makes aiding support bar 2 mobile in vertical direction simultaneously.
As shown in Figure 1, when the pulling force that applies to handle 6 to the right, inserted link 7 and then moves right, and 9 springs 9 are compressed because being connected between buting iron and the packing ring.Because inserted link 7 and aiding support bar 2 are to be connected by the oat tail groove structure that tilts, when inserted link 7 moved right, auxiliary support bar 2 slided relatively along dovetail groove, so but aiding support bar 2 in the vertical directions move down.At this moment keep handle 6 pulling force to the right constant, the workpiece of preparing clamping hung put in place, namely aiding support bar 2 above, but contact with it.Then, remove the pulling force of handle 6, inserted link 7 is moved to the left fast.8 ° of dovetail groove inclined-planes of inserted link 7 just make aiding support bar 2 move up, and when aiding support bar 2 tops contacted with workpiece, workpiece can produce a downward reaction force to cramp bar.At this moment, first nut 8 is screwed towards buting iron 4 directions, make first nut contact buting iron, avoid inserted link to be moved to the left like this, then second nut 11 is screwed towards spring 9 directions, be in compressive state fully until spring 9, because spring is connected to the buting iron left side, avoid inserted link to move right like this, so far, inserted link 7,2 self-lockings simultaneously of aiding support bar, spring 9 keeps complete compressive state.After inserted link 7, aiding support bar 2 formed self-locking, auxiliary support bar 2 had namely maintained static, and when clamping next one workpiece, its black skin can guarantee just in time to contact with the top of auxiliary support bar, realizes continuous productive process like this.
Adjustable auxiliary support apparatus for the workpiece blank face of the present invention utilizes 8 ° of dovetail groove inclined-planes of inserted link 7 and dovetail structure and the aiding support bar 2 on the inclined-plane to link mutually, and reach the purpose of self-locking by self-locking device, be implemented on the workpiece blank face fast, accurately, the function of aiding support workpiece reliably.
More than disclosed only be a specific embodiment of the present invention, still, the present invention is not limited thereto, any those skilled in the art can think variation all should fall into protection scope of the present invention.
