The square box is arranged on one end of a frock platform through the locating pin. The square box is equipped with the fastening shaft, the fastening nut and the fastening cover board, which are connected in turn. One side of the square box is equipped with the height regulating seat. The other end of the frock platform is equipped with the second cardiac support. The first cardiac support is arranged on the frock platform between the height regulating seat and the second cardiac support. The square box, the height regulating seat, the first cardiac support and the second cardiac support are connected to the frock platform. The utility model is characterized in that first, with simple and fast performances, the utility model is easy to be operated and is convenient for daily repair and maintenance. Second, the problems of a driving wheel and the rail chain partial wear are solved perfectly. Third, the labor intensity and the economic cost are lowered. Forth, the utility model is beneficial for the batch production developed by the excavator production enterprises.
Description
Technical field
The utility model relates to a kind of track frame welding tooling, particularly a kind of general welding fixture for track frame of excavator.
Background technology
At present, under the existing at home manufacturing technology background, welding to the excavator track frame all need be carried out on welding tooling, common welding tooling parts are formed and general frock similar, the steel plateelements different by thickness are welded into clamping device, and this presss from both sides northern device and is fixed on the platform, screw bolt on the device, adjust the back-out length of bolt and come dieback crawler belt beam, realize that the location clamps; When the weld motor seat, also be that it is placed on the device of special axle rank, axle rank device is to fix with platform, be to form by steel plateelement and steel pipe assembly welding, the axle that cooperates with the motor installed surface in the axle rank device can be realized flexible the adjustment by the handwheel rotation that is welded into one with axle, the motor seat is used the locked location of bolt when flexible during to suitable position.At this moment, whole spot welding is shaped.Yet common frock is placed on respectively in the different frocks and welds often with left and right sides track frame workpiece, and stuck phenomenon also often appears in handwheel when rotated.The CD-ROM drive motor center line and the motor mount plate center line goodness of fit also are difficult to control, and common frock is that the crawler belt beam both sides outline plate symmetry application of force is clamped, but not general frock the heart is clamped automatically so just is difficult to the size and the tolerance of control crawler belt beam and motor seat.These common frocks not only occupy big quantity space, manufacturing and maintaining are also very loaded down with trivial details, operator's labour intensity is also high, the such parts of the employed frock platform of different frocks all need design iterations, manufacturing, drop into a large amount of financial cost, owing to use unskilled labor to put into the row welding, also can not get all the time solving for driving wheel and rail chain eccentric wear problem, hindered the batch process of enterprise greatly.
Summary of the invention
The purpose of this utility model is that a kind of convenient to use, general welding fixture for track frame of excavator of reducing labour intensity and production cost, being convenient to maintain will be provided.
The purpose of this utility model is achieved in that this general Welder is equipped with square chest, fastener shaft, clamp nut, fastening cover plate, height adjustment seat, shop bolt, first pair of heart supporting seat and second pair of heart supporting seat, square chest is installed in an end of frock platform by shop bolt, on square chest, there are fastener shaft, clamp nut and fastening cover plate also to be connected successively, side at square chest has the height adjustment seat, the other end at the frock platform has second pair of heart supporting seat, on the frock platform between the height adjustment seat and the second pair of heart supporting seat first pair of heart supporting seat is arranged; Square chest, height adjustment seat, first pair of heart supporting seat, second pair of heart supporting seat all are connected on the frock platform.
Beneficial effect: owing to adopt such scheme, the motor seat of track frame is placed on the locating slot of square chest; Again the crawler belt beam is placed on the first pair of heart supporting seat and the second pair of heart supporting seat, adjust the height adjustment seat, it is vertical with the frock flat surface to make the motor seat reach solder side, at this moment, fix clamp nut and fastening cover plate on the square chest, make motor seat positioning and locking, the crawler belt beam is in the special shape of first pair of heart supporting seat and second pair of heart supporting seat with in self under the acting in conjunction of gravity, realize accurately location, convenient to use, reduce labour intensity and production cost, be convenient to maintenance, reached the purpose of this utility model.Advantage: 1, be convenient to manipulate, simple and fast also is convenient to the regular maintenance and the maintenance of frock; 2, solve driving wheel and rail chain eccentric wear problem well; 3, reduce labour intensity and financial cost; 4, help the batch process that excavator manufacturing enterprise carries out.

The specific embodiment
Embodiment 1: this general Welder is equipped with square chest 1, fastener shaft 2, clamp nut 3, fastening cover plate 4, height adjustment seat 5, shop bolt, first pair of heart supporting seat 6, second pair of heart supporting seat 7, motor seat 8, crawler belt beam 9 and frock platform 10, square chest 1 is installed in an end of frock platform 10 by shop bolt, fastener shaft 2 is arranged on square chest, clamp nut 3 also is connected successively with fastening cover plate 4, side at square chest has height adjustment seat 5, the other end at frock platform 10 has second pair of heart supporting seat 7, on the frock platform between the height adjustment seat 5 and the second pair of heart supporting seat 7 first pair of heart supporting seat 6 is arranged; Square chest, height adjustment seat, first pair of heart supporting seat, second pair of heart supporting seat all are connected on the frock platform.
Square chest 1 is a symmetrical structure, when the crawler belt beam workpiece of the different left and right sides of welding, as long as the direction of corresponding transposing fastener shaft and fastening cover plate.Wherein, the fastening of motor seat realize by fastener shaft, along y to bulk by the special axle rank control on the square chest; By the acting in conjunction of self gravitation and height adjustment seat 5, the location of realizing the motor seat.The crawler belt beam at z to realizing by self gravitation and the first pair of heart supporting seat 6, second pair of heart supporting seat 7, and, the free degree control that the symmetrical structure of the first pair of heart supporting seat 6, second pair of heart supporting seat 7 is realized the crawler belt beam with clamp.It mainly is the goodness of fit of control square chest, two supporting seat center lines and platform center line that the symmetry of form and position tolerance requires, to guarantee the dimensional requirement of track frame after welding.
This frock is placed to motor seat 8 on the locating slot of square chest earlier in use; Again crawler belt beam 9 is placed on the first pair of heart supporting seat and the second pair of heart supporting seat.Adjust the height adjustment seat, it is vertical with flat surface to make the motor seat reach solder side, at this moment, fixes the clamp nut on the square chest, makes motor seat 8 positioning and lockings.The crawler belt beam reaches accurate location to first pair of heart supporting seat of the heart and the second pair of special shape of heart supporting seat with in self under the acting in conjunction of gravity.Next, just can spot welding moulding.Leave standstill cooling a period of time through full weld, beat the internal stress that discharges storage, change next process over to, ball blast, spraying is rolled off the production line.
