Abstract
The invention discloses a welding table of an auxiliary frame of an electric car, and relates to the technical field of electric car manufacturing. The welding table comprises a lower frame and an upper frame, wherein the lower frame is composed of longitudinal beams and transverse beams, and the upper frame is stacked above the lower frame and composed of longitudinal beams and transverse beams. The lower frame is at least provided with two supporting devices ejecting the upper frame. One ends of the supporting devices are hinged to the transverse beams of the lower frame, and the other ends of the supporting devices are hinged to the upper transverse beam of the upper frame. The two sides of the lower frame are provided with two or more pairs of upper hinge bases and lower hinge bases, the two sides of the upper frame are provided with two or more pairs of upper hinge bases and lower hinge bases, and the upper hinge bases and the lower hinge bases are hinged through movable pins. The left side and the right side of the upper frame are each provided with two or more fastening devices. The welding table can solve the problems that a current electric car auxiliary frame is low in welding efficiency, and the welding quality is not effectively guaranteed.
Description
Technical field
The present invention relates to electric automobile manufacturing technology field, especially a kind of welding stand for the welding of electric automobile subframe.
Background technology
Electric automobile frame is generally divided into main car frame and subframe, and subframe is vitals lorry compartment and main car frame coupled together, and subframe welding is mostly carry out on jig, subframe jig is generally one flat plate, this flat board is welded with some assembly welding fixture or location-plates, after subframe assembly welding, subframe need overturn when carrying out welding to each bar weld seam by welder, simultaneously for reducing the welding deformation of subframe, also need with some plain clamps, subframe to be fixed temporarily, so, some welding positions are not easy welding, welder is also required to be fixed joint vehicle frame increases much unnecessary work, thus welding efficiency is decreased, simultaneously, welding quality also can not be guaranteed.
Summary of the invention
The object of this invention is to provide a kind of electric automobile subframe welding bench, it can solve, and current electric automobile subframe welding efficiency is low, welding quality can not get the problem that effectively ensures.
In order to solve the problem, the technical solution used in the present invention is:
This electric automobile subframe welding bench, comprise the lower floor's frame be made up of longitudinal and cross beam and the upper bed rack be made up of longeron, crossbeam be stacked on described lower floor frame, described lower floor frame is at least provided with the bracing or strutting arrangement of upper bed rack described in two jack-up, the crossbeam of described bracing or strutting arrangement one end and described lower floor frame is hinged, and the upper strata crossbeam of its other end and described upper bed rack is hinged; The both sides of described lower floor frame and described upper bed rack are respectively arranged with two to above upper free bearing, lower free bearing, and it is hinged that described upper free bearing and lower free bearing pass through removable pin; The left and right sides of described upper bed rack is respectively equipped with the fastener of more than two.
In above technical scheme, further scheme can be: described fastener comprises securing bracket and is arranged on the fastening bolt of described securing bracket one end, the other end of described securing bracket by upper free bearing and described upper bed rack hinged, described upper free bearing is also provided with locking pin.
Further: described bracing or strutting arrangement is cylinder or oil cylinder.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, welding stand is divided into upper and lower two parts by the present invention, is connected between them by movable free bearing, the below of welding stand is provided with overturning oil cylinder, can makes upper strata weld holder arbitrary overturn in the lateral direction; 2, the present invention is fixed with locking device on upper strata welding stand, can be fixed on by subframe easily on welding stand, greatly reduce welding deformation; 3, the present invention can improve welding efficiency and the welding quality of subframe.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is top view of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
This electric automobile subframe welding bench, as shown in Figure 1 and 2, comprise lower floor's frame 7 of being made up of longitudinal and cross beam and be stacked on upper bed rack 3 on lower floor's frame 7, that be made up of longeron, crossbeam, lower floor's frame 7 is provided with the bracing or strutting arrangement 9 of two jack-up upper bed racks 3, in the present embodiment, bracing or strutting arrangement 9 is cylinders, is arranged on the center line of lower floor's frame 7, wherein the cylinder barrel end of cylinder and the crossbeam of lower floor's frame 7 hinged, the upper strata crossbeam 11 of its tailpiece of the piston rod and upper bed rack 3 is hinged; The both sides of lower floor's frame 7 and upper bed rack 3 are respectively arranged with two to upper free bearing 5, lower free bearing 6, and it is hinged that upper free bearing 5 and lower free bearing 6 pass through removable pin 12; The left and right sides of upper bed rack 3 is respectively equipped with the fastener of more than two, in the present embodiment, fastener is each three around, fastener comprises the securing bracket 1 of bending shape and is arranged on the fastening bolt 2 of securing bracket 1 one end, fastening bolt 2 passes from the screwed hole of securing bracket 1, and stretch out from another side, the other end of securing bracket 1 is hinged with upper bed rack 3 by upper free bearing 4, and upper free bearing 4 is also provided with locking pin 13, and locking pin 13 is through the through hole being arranged on upper free bearing 4 and securing bracket 1.
During use, electric automobile subframe is placed on the upper end of upper bed rack 3, is pulled above upper bed rack 3 by securing bracket 1, then locking pin 13 is passed the through hole of upper free bearing 4 and securing bracket 1, rotates firm bolt 2 and makes its lower end withstand subframe to be welded; In welding process, if need to rotate subframe to be welded, only the removable pin 12 of side need be extracted, start cylinder, such upper bed rack 3 is just propped up.
