Description

A kind of weld jig

Technical field

The utility model belongs to the welding processing equipment field, especially relates to a kind of weld jig that is applicable to the power transmission and distribution switchgear assembly.

Background technology

In the existing welding processing process, there is not the auxiliary welding of reliable positioning equipment, can only be to carry out measurement and positioning earlier, weld then, especially when allocated transmission complete equipment processing cabinet beam part, can only lean on rough method to determine the position of workpiece, Han Jie workpiece error is big like this, efficient is low, the positional precision error is bigger, is difficult to improve the product retaining.

Summary of the invention

The purpose of this utility model is to improve the deficiency of prior art and a kind of reliable, clamping workpiece convenience, novelty simple in structure, simple operation, weld jig applied widely of locating is provided.

The utility model is to realize like this, a kind of weld jig, form by base plate, being characterized in that a end at base plate is provided with is fixed with mounting angle plate, base plate is provided with can be along the mobile bent plate of base plate running fix, the facade of mounting angle plate and mobile bent plate is relative, be connected the location swivel nut by loose pin on the facade of mounting angle plate and mobile bent plate, on base plate, be interval with vee-block, dog screw is housed on the vee-block, have the T-slot that T type nut is installed on the base plate of the other mobile bent plate side of vee-block, the plane of structure of mobile bent plate is provided with handle set, and handle set is respectively by a straight pin and handle, screw rod connects, screw rod can cooperate fixing with T type nut, vee-block is other to be provided with an end and to be fixed on double threaded screw on the base plate, and the other end is provided with the pressing plate that can cover the vee-block opening, is with spring on the double threaded screw.

In order further to realize the purpose of this utility model, can be to be provided with rest pad in the inboard of two arms of vee-block, back-up block by the bolt activity orientation on vee-block.

Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model is equipped with alignment pin on mounting angle plate and mobile bent plate, the location swivel nut is that the location benchmark is contained on the alignment pin with the endoporus, realize radial location, the alignment pin end thread connects location swivel nut internal thread, rotating loose pin just can be fastened on the location swivel nut on the facade of mounting angle plate and mobile bent plate, realize the axial location of location swivel nut, like this, just realized the location of swivel nut in anchor clamps, location; Vee-block is housed on base plate, outer surface with workpiece serves as that the location benchmark is contained on the vee-block, to realize the location of workpiece, with the pressing plates workpiece on vee-block, on base plate, have T-slot, the T-slot nut is arranged in the groove, turning handle just can drive handle set by straight pin and by straight pin drive screw rod mobile bent plate is fixed on the base plate, as long as mobile bent plate is contained in the corresponding groove, facade just can obtain different length position locations by the dog screw on the last vee-block, makes mobile bent plate stationary positioned; Rest pad is housed on the vee-block, is used for adjusting the rigging error of processing composition error and causing, to obtain optimum size and to obtain stable location benchmark.
