The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the finding registration device that a kind of restricted clearance uses, comprise cylinder 1, locating dowel pin 2, actuator 3, bracing frame 4, described cylinder 1 is connected with support frame as described above 4, described cylinder 1 is connected with described actuator 3, and described locating dowel pin 2 is fixed on the described actuator 3, and the fixing device of described finding also comprises sliding damper 5; Described sliding damper 5 is along moving with the direction of described cylinder 1 motion vertical; Support frame as described above 4 is provided with the knock hole that described locating dowel pin 2 energy levels are inserted.This cylinder 1 is the compact cylinder, does whole registration device little as far as possible.The above actuator 3 of one termination of described cylinder 1, in the promotion stroke of described cylinder 1, this actuator 3 promotes described locating dowel pin 2 motions under the application force of cylinder, when described locating dowel pin 2 during near support frame as described above 4, locating dowel pin inserts the knock hole on the accurate support frame as described above 4, this knock hole then is the knock hole of finding, and soldered finding is because which is provided with the hole, then be suspended on the described locating dowel pin 2 by this hole, the tip of described locating dowel pin 2 is near described sliding damper 5, described sliding damper 5 props up described locating dowel pin 2, prevents that locating dowel pin 2 from producing skew.
Support frame as described above 4 is provided with the part non-breathing zone; Described knock hole is located in the described part non-breathing zone; Described part non-breathing zone is provided with magnetic part.Described magnetic part is a magnet, by the effect of magnetic force, finding is fixed on the described locating dowel pin 2, keeps finding not produce skew, and in order to obtain better effect, selects the size of magnetic patch according to the force request of finding.
The finding registration device that described restricted clearance uses also comprises slide shaft 6; Described sliding damper 5 of described slide shaft 6 break-through and support frame as described above 4.Described slide shaft 6 is provided with spring 7; Described spring 7 is on described slide shaft 6.Described sliding damper 5 is provided with and described slide shaft 6 axially parallels and vertical horizontal part and vertical component effect, and described vertical component effect is provided with breach; Described horizontal part is provided with perforation; Described slide shaft 6 inserts described perforation.
Support frame as described above 4 is provided with vertical with described slide shaft 6 direction of slips outstanding barrier portion 8; Described outstanding barrier portion 8 is located at the middle limit portion of support frame as described above 4 respectively; Described outstanding barrier portion 8 is provided with the through hole of symmetry; Described slide shaft 6 inserts in the described through hole.Described spring 7 cooperates with described sliding damper 5 extruding; Described spring 7 is the self-righting compression spring of no external force effect; The end of described spring 7 props up the side of described sliding damper 5; And the compressive force of compression spring need carry out roughly calculating according to the size of part, and then obtains the parameters size of spring, and the spring housing that will be complementary is on described slide shaft 6 afterwards.
The end of described slide shaft 6 is provided with connecting element; Described connecting element is fixed described slide shaft 6.The end of described slide shaft 6 is provided with the hole; Described connecting element is by the fixing described slide shaft 6 in described hole.When the end of described slide shaft 6 is provided with through hole, can insert in the described through hole by a screw rod, thereby fixing described slide shaft 6 guarantees that described slide shaft can not move; Described spring 7 then can move on described slide shaft.
Be provided with the gap between the vertical component effect of described sliding damper 5 and the support frame as described above 4 or be in contact with one another; Being shaped as of described sliding damper 5 is Z-shaped; The vertical component effect of described sliding damper 5 can be in contact with one another with bracing frame 4, also can leave the slit.According to the difference of finding, can change different bracing frames, and finding is fixed in the non-breathing zone of bracing frame, this non-breathing zone can be a district that falls in, also can be with support frame as described above 4 on same plane.
Because the finding of many mounting brackets and so on is arranged on the vehicle body, and very difficult assurance can not appear near the conveying space; Mounting bracket generally is to be welded on the large-scale part simultaneously, by the nut bore on the support other part is installed then, in order to guarantee to need from locating dowel pin, to take out after mounting bracket welds, and, adopt cylinder to drive the interference of locating dowel pin motion can not causing locating dowel pin and part according to the different selected different bracing frames of finding rule.
The work specific as follows of this registration device: cylinder 1 beginning stroke, locating dowel pin 2 is pushed ahead, after cylinder 1 stroke used up, this locating dowel pin 2 reached the position (the perforating branch support reaches a correct position) that needs.Promote 1 sliding damper 5 along slide shaft 6 to the right compression spring 7 with external force this moment, be installed in finding in the non-breathing zone of bracing frame 4 this moment, after installing finding, decontrol described sliding damper 5, this moment, described spring advanced described sliding damper 5 left to left movement because external force discharges, reach not motion state before, this moment, described sliding damper 5 propped up described locating dowel pin 2.After welding finishes, this cylinder 1 withdrawal stroke, this returns original position.
Because magnet is installed in above the bracing frame 4, at the back side of finding, the magnetic force of magnet makes finding be close to this bracing frame 4, thereby limits the degree of freedom of this finding at directions X.Under no external force effect, the compressive force of spring 7 extruding sliding damper 5 makes sliding damper 5 be close to the left end of slide shaft 6.Prevent that finding from the dislocation of directions X taking place under external force, thereby guarantee the accuracy rate of location.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
