Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail:
As shown in Figures 1 to 6, this utility model includes 2 living first ring gears 1 and living first support 4 of 3,1 central shaft of the second ring gear 2,2 and the parts such as living first bracket base 5 of 7,2, the second support and the second bracket base 6, first described ring gear the 1, second ring gear 3 be one with pore area step in a section and end face uniform the annulus pipe nipple of 4 concave tooth, the width of concave tooth is somewhat big (width of concave tooth is somewhat than the big 0.3mm of arculae width of centralizer) than the arculae width of centralizer.The length of the concave tooth distance from bottom endoporus step of first ring gear the 1, second ring gear 3 is consistent with the length of centralizer spring band end face distance arculae end face.Central shaft 2 is the long barrier part with a location block plate.First bracket base 5 and the second bracket base 6 are one to have certain thickness square iron plate.First support 4 and the second support 7 are that one " ten " font iron plate (preferably has the shape of V-arrangement self-centering function, such as cross, V-type, cross is easy to make simply, with a block plate gas cutting across just energy molding, V-arrangement needs to weld one flat plate below, semicircle can also, but do not possess self-centering function, need both radius consistent guarantee central shafts not roll.) the first support 4 and the second support 7 distribution weld together with the first bracket base 5 and the second bracket base 6.The support welded together can be stood, and two welding supports (being welded by support and bracket base) are used for supporting central shaft 2.The tooth of the first ring gear 1 and the second ring gear 3 is to being inserted on central shaft 2.
During use, first 2 welding supports are ajusted, place suitable distance.Being inserted on central shaft 2 by first ring gear 1, the block plate without increment face with central shaft 2 contacts.Spring band is also inserted on central shaft 2, reach in the first ring gear 1 always, contact with the endoporus step of the first ring gear 1 that (at ring gear endoporus minor diameter, diameter is less than the external diameter of spring band, internal diameter equal to spring band, but it is greater than the diameter (big about 0.3mm) of central shaft, diameter at ring gear endoporus major diameter is greater than the external diameter (big about 0.3mm) of spring band) another spring band is put in the second ring gear 3, contact with the endoporus step of the second ring gear 3, being inserted in the most together on central shaft 2, tooth is placed by the first ring gear 1 and the second ring gear 3 tooth.To be placed horizontally on 2 welding supports with the central shaft 2 of the first ring gear 1 and the second ring gear 3 and spring band.Take a piece of arcuate tab, the two ends of arcuate tab are respectively embedded in the tooth of the first ring gear 1 and the second ring gear 3, then compress the second ring gear 3, make the two ends of arcuate tab completely attach to at the bottom of the tooth of the first ring gear 1 and the second ring gear 3 respectively, the two ends of arcuate tab are blocked by concave tooth, it is ensured that point-blank.Now start at the end of the second ring gear 3, start welding, arcuate tab and spring band are welded together, weld at the end of the first ring gear 1 the most again, arcuate tab and spring band are welded together.3 arcuate tab of residue it are soldered in the same way after being soldered first arcuate tab.After the welding of all arcuate tab, central shaft 2 is lifted, with block plate end upward, the other end down, now, centralizer after welding and the first ring gear 1 and the second ring gear 3 will Automatic-falling, complete the welding of a centralizer.
This frock is capable of arcuate tab radial and axial being accurately positioned on spring band, it is to avoid artificial line, has saved cost of labor, and simple to operation, efficiency is greatly improved, be a kind of more satisfactory welding tooling.
This utility model is according to the structure of elastic centralizer, devise the length of the interior step distance section of 2 ring gears, and the degree of depth of concave tooth (degree of depth of concave tooth is less than or equal to the length of arcuate tab and spring band non-solder, such as, drawing requirement non-solder part not can exceed that 20mm, the actual deep 15mm of concave tooth) and width, can just meet design requirement after being allowed to welding；According to the internal diameter size of centralizer spring band, the excircle dimension diameter of the central shaft (< diameter, little 0.3mm at the internal diameter of spring band=ring gear minor diameter) devising central shaft 2 enables spring band slidably and radially not jump on central shaft 2；According to the outside dimension of centralizer spring band, devise the internal diameter size of 2 ring gears, enable spring band easily to enter ring gear and radially not jump；Central shaft 2 can be gone up the most freely rotatable at welding support (being welded by support and bracket base) and can take off, convenient welding and postwelding pickup；A block plate is designed, centralizer assembly axial jump when this block plate is possible to prevent to weld on central shaft 2.
The first ring gear and the material of the second ring gear in this utility model are aluminum, and remaining parts and elastic centralizer are all steel, because ring gear is aluminum component (aluminum is the most solderable), so when being welded near ring gear, ring gear will not be welded in together.
Support and bracket base are all to be formed by steel plate gas cutting, and cost is the lowest.This device can save the crossed process before centralizer weldering, not only saves human cost, and welding precision is high, and centralizer quality is guaranteed.This device makes welding process convenient and swift, and efficiency is greatly improved, and has broad application prospects.
Technique scheme is a kind of embodiment of the present utility model, for those skilled in the art, on the basis of the utility model discloses principle, it is easy to make various types of improvement or deformation, it is not limited solely to the structure described by the above-mentioned specific embodiment of this utility model, the most previously described the most preferred, and the most restrictive meaning.
