Abstract
The invention discloses an application method of a positioning structure for stud welding. The application method comprises the steps that (A) a threaded end of a weld stud penetrates through a through hole to be matched with a nut, and a whole positioning device is put to a required place; (B) a welding end of the weld stud is in contact with and tight attaching onto the surface of a rear frame, and electric welding is performed on the contact position of the welding end and the surface of the rear frame through an electric arc welder; (C) after the welding end of the weld stud melts, a positioning screw is rotated to apply a certain pressure on the weld stud, and welding is completed. Due to the fact that the position of the through hole in a vertical positioning plate is unchanged, the relative position of the weld stud is unchanged. The application method of the positioning structure for stud welding is simple in operation, accurate in positioning, small in error and strong in practicability.
Description
Technical field
The present invention relates to a kind of servicing unit, relate in particular a kind of using method of welding a kind of location structure of stud welding for Rear frame of loader.
Background technology
The rear vehicle frame of loading machine is after connection during vehicle frame staircase, first staircase is installed in welding screw positioning welding rear, welding screw is generally four, relative position is each other generally fixing, present welding screw is to weld together to avoid relative position between double-screw bolt to change staircase and double-screw bolt and the assembly problem that brings in when welding mostly, but so not only complex procedures is various, and waste time and energy, simultaneously due to human error, the relative position of welding screw also can be variant, accurate not, be unfavorable for later stage assembling.
Summary of the invention
The invention provides a kind of using method of location structure of stud welding, for solving welding screw welding sequence complexity, the coarse problem in position of Rear frame of loader staircase.
For solving above-mentioned technical problem, the present invention by the following technical solutions: a kind of using method of location structure of stud welding, (A) end of thread of welding screw is coordinated with nut through through hole, whole positioner is positioned over to desired location; (B) welding ends of welding screw contacts and fits tightly with rear vehicle frame face, uses arc welder to carry out electric welding to it; (C) after welding screw welding ends melts, rotation positioning screw applies certain pressure to welding screw, completes welding, because the lead to the hole site on vertical location-plate immobilizes, so the double-screw bolt relative position of welding can not change yet like this; In above-mentioned steps, the fixed head front end face left and right sides is all connected with vertical location-plate, vertically location-plate upper and lower is provided with through hole, described vertical location-plate is being connected with nut with a side of fixed head joint face, nut is over against through hole setting, and described positioning screw coordinates with nut thread and through vertical location-plate through hole.During use, positioning screw, nut, through hole and double-screw bolt all arrange with one heart, the self-position of double-screw bolt in welding process can not change yet like this, positioning screw is to double-screw bolt also along axis, and by assisting of positioner, the welding position precision of welding screw is higher, error is less, and easy for installation, technique is simple, practical.
Middle part, described fixed head upper surface is also connected with two connecting plates, and connecting plate front end face is connected with link plate.Link plate is directly hung on rear vehicle frame and can be welded, without carrying out supporting and positioning device by other supporting constructions, use simple.
Described two connecting plates are parallel to each other and be certain arranged with interval, and described link plate is L-type and link plate is horizontally set on connecting plate front end face.For guaranteeing vertical location-plate stress balance, avoid double-screw bolt to occur tilt phenomenon, so two connecting plates are parallel to each other and be certain arranged with interval, can keep like this balance of the right and left, link plate is L-type in order conveniently to hang and take device.
It also comprises two balance plates, and two balance plates are positioned at fixed head left and right sides.Balance plate is for strengthening the vertical location-plate stress balance of the right and left, balance plate is arranged on the fixed head left and right sides simultaneously, and fixed head is positioned at vertical location-plate middle part, balance plate can also guarantee the balance of vertical location-plate upper/lower terminal like this, makes four double-screw bolts can be perpendicular to solder side setting.
Compared with prior art, the invention has the beneficial effects as follows: it is this for welding a kind of using method of location structure of stud welding, simple to operate that the present invention designs, accurate positioning, error is less, practical.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is the decomposition texture schematic diagram of embodiment.
Label in figure is: 1, positioning screw; 2, nut; 3, balance plate; 4, vertical location-plate; 5, connecting plate; 6, link plate; 7, fixed head.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.Embodiments of the present invention include but not limited to the following example.
Embodiment
The using method of the location structure of a kind of stud welding as shown in Figure 1, (A) coordinates through through hole the end of thread of welding screw with nut, whole positioner is positioned over to desired location; (B) welding ends of welding screw contacts and fits tightly with rear vehicle frame face, uses arc welder to carry out electric welding to it; (C) after welding screw welding ends melts, rotation positioning screw applies certain pressure to welding screw, completes welding, because the lead to the hole site on vertical location-plate immobilizes, so the double-screw bolt relative position of welding can not change yet like this; In above-mentioned steps, the fixed head 7 front end face left and right sides are all connected with vertical location-plate 4, vertically location-plate 4 upper and lowers are provided with through hole, described vertical location-plate 4 is being connected with nut 2 with a side of fixed head 7 joint faces, nut 2 is over against through hole setting, and described positioning screw 1 is with nut 2 threaded engagement and through vertical location-plate 4 through holes.
Described fixed head 7 middle parts, upper surface are also connected with two connecting plates 5, and connecting plate 5 front end faces are connected with link plate 6.
Described two connecting plates 5 are parallel to each other and be certain arranged with interval, and described link plate 6 is L-type and link plate 6 is horizontally set on connecting plate 5 front end faces.
It also comprises that 3, two balance plates 3 of two balance plates are positioned at fixed head 7 left and right sides.
When the present invention uses, because the lead to the hole site on vertical location-plate 4 immobilizes, so the double-screw bolt relative position of welding can not change yet like this, precision is higher, positioning screw 1, nut 2, through hole and double-screw bolt all arrange with one heart simultaneously, the self-position of double-screw bolt in welding process can not change yet like this, when the 1 pair of double-screw bolt of positioning screw is afterburning also along axis, by assisting of positioner, the welding position precision of welding screw is higher, and error is less, and easy for installation, technique is simple, practical.
Be as mentioned above embodiments of the invention.The present invention is not limited to above-mentioned embodiment, and anyone should learn the structural change of making under enlightenment of the present invention, and every have identical or close technical scheme with the present invention, within all falling into protection scope of the present invention.
