A kind of welding screw positioner of good positioning effect
Technical field
The utility model relates to a kind of servicing unit, relates in particular a kind of welding screw positioner of the good positioning effect for Rear frame of loader.
Background technology
The rear vehicle frame of loading machine is after connection during the vehicle frame staircase, at first staircase is installed at welding screw positioning welding rear, welding screw is four generally speaking, relative position each other is generally fixing, present welding screw is to weld together to avoid relative position between the 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 because human error, the relative position of welding screw also can be variant, accurate not, be unfavorable for the later stage assembling.
The utility model content
The utility model provides a kind of welding screw positioner of good positioning effect, is used for solving the coarse problem in welding screw welding position of Rear frame of loader staircase.
For solving above-mentioned technical problem, the utility model is by the following technical solutions: a kind of welding screw positioner of good positioning effect, comprise fixed head and positioning screw, the fixed head front end face is left, right both sides all are connected with vertical location-plate, vertically the location-plate upper and lower is provided with through hole, described vertical location-plate is connected with nut in the side with the fixed head joint face, nut is over against the through hole setting, described positioning screw cooperates with nut thread and passes vertical location-plate through hole, described positioning screw also is connected with hold-down column at vertical location-plate front end face, hold-down column both sides end face is provided with vertically and cooperates screw and locating hole, and described locating hole cooperates with positioning screw positioning screw is connected with hold-down column.During use, the end of thread of welding screw is connected with the cooperation screw of hold-down column, whole positioner is positioned over desired location, the welding ends of welding screw contacts and fits tightly with rear vehicle frame face, use arc welder that it is carried out electric welding, the rotation positioning screw applies certain pressure to welding screw after the welding screw welding ends melts, hold-down column compresses double-screw bolt under positioning screw drives, finish welding, because vertically the lead to the hole site on the location-plate immobilizes, so the double-screw bolt relative position of welding can not change yet like this, precision is higher, simultaneously 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, also along axis, by assisting of positioner, the welding position precision of welding screw is higher to the double-screw bolt reinforcing for positioning screw, error is less, and easy for installation, technique is simple, and is practical; The cooperation screw of hold-down column is not communicated with each other with locating hole, cooperate the size of screw to decide according to no double-screw bolt diameter, and its integral body was pressurizeed to double-screw bolt when hold-down column compressed, than the direct employing positioning screw more uniform force application of pressurizeing, the phenomenon that double-screw bolt can not occur tilting when pressurization, good positioning effect, welding quality is high.
Middle part, described fixed head upper surface also is connected with two connecting plates, and the connecting plate front end face is connected with link plate.Link plate is directly hung on the rear vehicle frame and can weld, need not to come supporting and positioning device with 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 the connecting plate front end face.For guaranteeing vertical location-plate stress balance, avoid double-screw bolt tilt phenomenon to occur, 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 then in order conveniently to hang and take device.
Spacing between described two connecting plates is the 1/4-3/4 of fixed head length.Be to strengthen counterbalance effect, the spacing between two connecting plates should be not too small, and the excessive operation that then can have influence on positioning screw of spacing gets final product so the spacing setting between two connecting plates is the 1/4-3/4 of fixed head length.
It also comprises two balance plates, and two balance plates are positioned at the fixed head left and right sides.Balance plate is used 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 the solder side setting.
Compared with prior art, the beneficial effects of the utility model are: this positioner for the welding screw welding of the utility model design, can be used for the welding screw of different-diameter, and good positioning effect, error is less, and is practical.
