Description
Technical field
The utility model relates to a kind of servicing unit, relates to a kind of positioner for vehicle frame welding screw welding behind the loading machine in particular.
Background technology
The back vehicle frame of loading machine is after connection during the vehicle frame staircase, at first staircase is installed at welding rear, welding screw location, welding screw is four generally speaking, relative position each other is generally fixing, present welding screw the time is to weld to avoid relative position between the double-screw bolt to change together staircase and double-screw bolt and the assembly problem that brings in 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 inadequately, be unfavorable for the later stage assembling.
The utility model content
The utility model provides a kind of positioner for the welding screw welding, for welding screw welding sequence complexity, the coarse problem in position of vehicle frame staircase behind the solution loading machine.
For solving above-mentioned technical problem, the utility model is by the following technical solutions: a kind of positioner for the welding screw welding, comprise fixed head and positioning screw, the fixed head front end face left and right sides all is 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, and nut is over against the through hole setting, and described positioning screw cooperates with nut thread and passes vertical location-plate through hole.During use, the end of thread of welding screw is passed through hole to be cooperated with nut, whole positioner is positioned over desired location, the welding ends of welding screw contacts and fits tightly with back 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, finish welding, owing to the lead to the hole site on the vertical location-plate immobilizes, so the double-screw bolt relative position of welding can not change yet like this, precision is higher, the while positioning screw, nut, through hole and double-screw bolt all arrange with one heart, and the self-position of double-screw bolt in welding process can not change yet like this, positioning screw to double-screw bolt also along axis, by assisting of positioner, the welding position precision of welding screw is higher, and error is less, and easy for installation, technology is simple, and is practical.
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 vehicle frame of back and can weld, need not to use other supporting constructions to come supporting and positioning device, use simple.
Described two connecting plates are parallel to each other and be determining deviation arrangement, and described link plate is the 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 a determining deviation and arrange, can keep the balance of the right and left like this, link plate is the L type and then hangs for convenience and get 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 between two connecting plates is set at the 1/4-3/4 of fixed head length.
It also comprises two balance plates, and two balance plates are positioned at fixed head left and right sides face.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, and simple to operate, accurate positioning, error is less, and is practical.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is decomposition texture schematic diagram of the present utility model.
Label among the 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 utility model is further described.Embodiment of the present utility model includes but not limited to the following example.
Embodiment
A kind of positioner for the welding screw welding as shown in Figure 1, comprise fixed head 7 and positioning screw 1, the fixed head 7 front end face left and right sides all are connected with vertical location-plate 4, vertically location-plate 4 upper and lowers are provided with through hole, described vertical location-plate 4 is connected with nut 2 in the side with fixed head 7 joint faces, nut 2 is over against the through hole setting, and described positioning screw 1 is with nut 2 threaded engagement and pass vertical location-plate 4 through holes.
Middle part, described fixed head 7 upper surfaces also is 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 a determining deviation and arrange, and described link plate 6 is the L type and link plate 6 is horizontally set on connecting plate 5 front end faces.
