Abstract
The utility model discloses a welding fixture of a lifting arm and a sector, comprising a bottom plate, wherein the bottom plate is provided with a reference block, an adjusting block and a sector positioning block, wherein the reference block is jointed with one side of the adjusting block; the other side of the adjusting block is jointed with one side of the sector positioning block; and the other side of the sector positioning block is an arc-shaped structure matched with the outer tooth edge of the sector. By adopting the structure, the welding fixture has the following advantages: 1. being capable of compensating the defect of weld assembly error caused by thermal expansion of the welding fixture; 2. reducing the dependence on the position precision of the circle and pitch circle where the sector positioning holes are positioned; and 3. having simple structure and convenient use.
Description
Technical field
The utility model relates to the electric elevator technical field, the welding tooling of particularly a kind of lifting arm and tooth fan.
Background technology
At present, the welding tooling of the lifting arm of common electric glass lifter and tooth fan as shown in Figure 4.The tooth fan is installed on the base plate 1 of this frock after welding with lifting arm, and the two ends of tooth fan are respectively equipped with the locating hole that varies in size, and it is fixing with the tooth fan that corresponding alignment pin passes two locating holes, and the tooth fan mainly relies on two alignment pins to be fixed on the base plate 1.Simultaneously,, cause the size of corresponding two alignment pins also different, can recognize the locating hole at tooth fan two ends so easily, prevent to make mistakes because two locating holes vary in size.The tooth fan of this welding tooling can not be transferred for fixing, and welding tooling thermal expansion originally can occur and cause that the alignment pin and the centre of gyration are apart from bigger than normal after being transmitted to welding heat for a long time.Simultaneously because the tooth fan is stamping parts; exist the situation of the error of decentraction to occur between the circle at two locating hole places and pitch circle through regular meeting; when this situation occurring, abnormal sound even stuck situation will appear in the gear pair that weldment and motor gear are formed in running.Therefore, developing the adjustable welding tooling in a kind of position, can compensate the weldment defect error that occurs owing to the welding tooling thermal expansion, reduce the dependence to the positional precision of the circle at tooth fan locating hole place and pitch circle, is the problem that prior art need solve.
The utility model content
The utility model provides the welding tooling of a kind of lifting arm and tooth fan, to reach by self adjustable and then compensation because the purpose of the weldment defect error that the welding tooling thermal expansion occurs.
For solving the problems of the technologies described above, the technical solution of the utility model is: the welding tooling of a kind of lifting arm and tooth fan, comprise base plate, described base plate is provided with reference block, adjusts piece and tooth fan locating piece, described reference block is fitted with a side of adjusting piece, adjust the opposite side of piece and a side of tooth fan locating piece and fit the arcuate structure that the opposite side of described tooth fan locating piece matches for the peripheral skirt with the tooth fan.
The upper surface of described reference block is provided with and covers reference block, adjusts the pressing plate of piece and tooth fan locating piece.
One end of the covering tooth fan locating piece of described pressing plate is provided with and the identical arcuate structure of tooth fan locating piece.
Also be provided with two eccentric lock bearings up pulley on the described base plate.
Described adjustment piece is the rectangular strip structure.
Described reference block is " L " template body, and it is fixed on the base plate by screw.
The utility model adopts said structure, has the following advantages: 1,, can compensate the weldment defect error that occurs owing to the welding tooling thermal expansion; 2, reduce dependence to the positional precision of the circle at tooth fan locating hole place and pitch circle; 3, simple in structure, easy to use.

In Fig. 1～Fig. 4,1, base plate; 2, reference block; 3, adjust piece; 4, tooth fan locating piece; 5, eccentric lock bearing up pulley; 6, pressing plate.
The specific embodiment
Welding tooling as Fig. 1～a kind of lifting arm shown in Figure 3 and tooth fan comprises base plate 1, and base plate 1 is provided with reference block 2, adjusts piece 3 and tooth fan locating piece 4.Reference block 2 is " L " template body, and it is fixed on the base plate 1 by screw.Adjusting piece 3 is the rectangular strip structure, and the thickness of adjusting piece 3 is 13mm to 13.3mm, is one every 0.1mm and adjusts class.Reference block 2 is fitted with a side of adjusting piece 3, adjusts the opposite side of piece 3 and a side of tooth fan locating piece 4 and fits the arcuate structure that the opposite side of tooth fan locating piece 4 matches for the peripheral skirt with the tooth fan.The upper surface of reference block 2 is provided with and covers reference block 2, adjusts the pressing plate 6 of piece 3 and tooth fan locating piece 4, and an end of the covering tooth fan locating piece 4 of pressing plate 6 is provided with the arcuate structure identical with tooth fan locating piece 4.Pressing plate 6 is pressed on reference block 2, adjustment piece 3 and the tooth fan locating piece 4 by bolt they is fixed.When being contained on this frock after tooth fan and the lifting arm welding, the peripheral skirt of tooth fan matches with the arcuate structure that tooth is fanned locating piece 4.The perforation at the two ends of tooth fan does not make improvements, and varying in size of two perforation is identification for convenience, prevents to make mistakes.1 also is provided with two eccentric lock bearings up pulley 5 on the base plate, and the two ends of tooth fan are approaching with two eccentric lock bearings up pulley 5 respectively.Endeavour eccentric lock bearing up pulley 5 and can finely tune by pushing away the position of tooth fan.When this welding tooling expanded by heating the weldment precision occurs and departs from the trend of given range, can change one grade of adjustment piece 3 according to detecting feedback result, to guarantee the qualification rate of weldment, its process is: unclamp bolt earlier and take off the pressing plate 6 that compresses tooth fan locating piece 4, Figure 2 shows that the structural representation of this frock after pressing plate 6 takes off, then extract the adjustment piece 3 of adjusting piece 3 and being replaced with another grade size out, push-tight eccentric lock bearing up pulley 5, make tooth fan, tooth fan locating piece 4 and adjustment piece 3 fit tightly and fix, press pressing plate 6 at last again.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
