Abstract
The invention relates to a processing method for welding supports on an irregular plate. The method comprises the following steps of: (1) bending the irregular plate to form a required shape; (2) mounting a template on a side face of the irregular plate; (2) respectively penetrating more than two positioning pins which are arranged on the template in connecting holes of the supports, and positioning the supports, wherein each support is an eccentric wheel; (4) rotating the supports along the respective positioning pin, so that edges of the supports are connected with the irregular plate; and (5) welding the supports and the irregular plate, and removing the template. The supports have an eccentric wheel structure and are positioned by the positioning pins, so that the supports can rotate along the central axis of the connecting holes under positioning of the positioning pins; and therefore, the distance between the connecting holes on the supports and the irregular plate can be changed, the structure is reasonable, the welding distance between the supports and the irregular plate can be rapidly and accurately controlled, the operation is convenient, and the production efficiency can be improved.
Description
Technical field
The present invention relates to a kind of bearing is welded on to the processing method on sketch plate, belong to the Machining Technology field.
Background technology
Sketch plate is generally used for the protection to main frame, and sketch plate is with sheet material bending or stamping, process at sketch plate exists mismachining tolerance, and it is improper to deposit process in transportation, also can make the shape of sketch plate change and irregularity, but usually can be fixed with a plurality of bearings on sketch plate, the connector be connected with sketch plate is to be arranged on each bearing by a plurality of securing members, therefore when the bearing on sketch plate has positioning requirements, tend to because of the sketch plate error is large or distortion after, when bearing is welded on sketch plate, because the distance between bearing and sketch plate changes, the welding position of bearing is changed, and cause welding inconvenient, reduce welding efficiency.
Excavator, scraper, push or the machineries such as smooth soil and sandstone, be widely used in construction, water conservancy construction, road construction etc., this type of machinery mostly drives some executive item work by motor.But this type of machine work environment is poor, for motor can be worked, usually can adopt a motor containment vessel to be protected motor, as shown in Figure 1, the motor containment vessel is the sketch plate 1 be shaped with a thicker steel plate bending, be welded with four bearings 2 for being connected with cover plate on motor containment vessel inwall, each bearing 2 is provided with screwed hole, when cover plate is fitted in the side of motor containment vessel, being screwed in cover plate by bolt 5 is connected on bearing 2, and prevent the loosening of bolt 5 by the packing ring 4 that is enclosed within bolt 5, make can keep less spacing between cover plate and motor containment vessel, prevent that earth from entering in motor.
See shown in Fig. 1,2, existing bearing 2 adopts square structure, arranges on bearing 2 and uses the screwed hole be connected with bolt 5, and bearing 2 has groove to increase the welding fastness at the weldment position, bearing 2 is welded on motor containment vessel inwall.During welding, by alignment pin, each bearing is positioned, because the distance between the screwed hole on bearing and sketch plate is a definite value, under normal circumstances, bearing can be welded on sketch plate.But the motor containment vessel scale error of bending technique is larger, especially improper in placement and transportation, the motor containment vessel can produce distortion again after bearing external pressure, while when needs, bearing being welded on motor containment vessel inwall or outer wall, between bearing after motor containment vessel after distortion makes to locate and motor containment vessel, distance also changes, when the screwed hole of bearing and the hypertelorism between the motor containment vessel, both can't be welded; And, when the screwed hole of bearing and the hypotelorism between the motor containment vessel, make again bearing and motor containment vessel produce and interfere, can not weld, not only increase the difficulty of bearing welding, and have a strong impact on welding production efficiency.
Summary of the invention
The purpose of this invention is to provide and a kind of bearing is welded on to the processing method on sketch plate, rational in infrastructure, and can quick and precisely control bearing and sketch plate welding distance, and easy to operate, can enhance productivity.
The present invention is that the technical scheme achieved the above object is: a kind of bearing is welded on to the processing method on sketch plate, it is characterized in that: carry out according to the following steps,
(1), at first sketch plate is bent into to required form;
(2), template is arranged on to the side of sketch plate;
, two above alignment pins that will be arranged on template are through respectively in the connecting hole of each bearing, and each bearing is positioned, and each bearing is eccentric wheel;
, by each bearing along alignment pin rotation separately, the edge of each bearing and sketch plate are joined;
(5), by each bearing and sketch plate welding, form removal.
Wherein: described eccentric wheel is circular wheel or oval wheel or cam, and the connecting hole on bearing is through hole or screwed hole.
Described template is provided with plural locating hole, and alignment pin is fixed on locating hole, or alignment pin is inserted on the locating hole of template.
Described template is provided with plural deck, and end face and the outer wall of deck and sketch plate join, or the end face of deck and sketch plate and inside and outside wall join.
Bearing of the present invention adopts eccentric wheel structure, and eccentric wheel is provided with connecting hole, when being welded on sketch plate by bearing, can be through in the connecting hole of bearing by the alignment pin be arranged on template, by each alignment pin, each bearing is positioned, because bearing can rotate by the central axis along its connecting hole under the location of alignment pin, thereby can change connecting hole on bearing and the distance between sketch plate, thereby solve due to sketch plate because of mismachining tolerance or distortion after, the distance between the connecting hole on each bearing and sketch plate does not wait and the problem that can not be welded.The present invention can conveniently adjust its welding position by eccentric bearing, even if after the sketch plate distortion, also can make the edge of each bearing all can join with sketch plate, both guaranteed that installing hole and the connecting hole on bearing on cover plate kept same axis, at bolt, can be easily installed in the connecting hole of bearing through the installing hole on cover plate, make cover plate can be attached to the end face of sketch plate, reach instructions for use, and can conveniently regulate the distance between each bearing and sketch plate again, adjust welding position, seat structure of the present invention is reasonable, and can quick and precisely control bearing and sketch plate welding position, by each bearing, can be welded on sketch plate, can increase substantially production efficiency.Bearing of the present invention adopts eccentric wheel structure, and adjustable is strong, can adapt to the bearing that is welded with positioning requirements on plane, curved surface, composite surface position.
