Description
Technical field
The utility model relates to a kind of weld jig, particularly a kind of for weld jig during automobile element manufacturing.
Background technology
In auto parts and components, often need to connect different parts with welding, be combined into parts, but this welding does not generally have special bonding machine, but adopt manual welding.Such as, the rectangular attached part B that welding one is little on a large body element A, as shown in Figure 1.Common way is first placed in body element by manual for add-on parts, and then spot weld operation personnel push down plate part on the other hand, and another hand carries out welding operation.The shortcoming of this way is: add-on parts small-sized, is located to be clamped in body element very difficult, and the relative position dimensional accuracy of add-on parts and body element does not reach product technology quality requirement.In addition, in welding process, labour intensity is higher, the operating experience of the workman that places one's entire reliance upon, and welding production efficiency is not high.
Summary of the invention
Not high in order to overcome existing product size precision of depositing after welding during the add-on parts at the right angle that welding one is little in a large body element, the shortcoming that defect rate is high, the utility model provides a kind of dimensional accuracy that can improve the rear product of welding, improves the welding pre-determined bit fixture of yield rate.
A kind of welding pre-determined bit fixture, the frame of this fixture has horizontal operation table top, and horizontal operation table top is provided with body element clamping and positioning in the agent localization mechanism of work top and the pre-locating mechanism of assigned address accessory part being positioned body element;
Pre-locating mechanism comprises clamp body, the elevating mechanism driving clamp body to move up and down and the support being positioned at the clamp body left and right sides, clamp body has the cavity volume of Set and Positioning add-on parts, first wall of cavity volume or the second wall are as the positioning reference plane of add-on parts, first wall is relative with the second wall, and the weld part of add-on parts exposes to cavity volume; 3rd wall of cavity volume and the 4th wall are as the clamping portion of add-on parts; When elevating mechanism makes clamp body be in primary importance, add-on parts is in specifies welding position; When elevating mechanism makes clamp body be in the second place, clamp body is away from the clamping position of body element.The clamping position of body element refers to body element and is clamped position when being positioned on work top, residing for body element.
Further, be provided with jacking block in clamp body, jacking block forms the 4th wall, add-on parts by clamping time, add-on parts to push against the 3rd wall in cavity volume by jacking block; Jacking block connects jacking force mechanism.
Further, jacking force mechanism is primarily of spring and baffle plate composition, and baffle plate and clamp body are fixed, and spring is located between jacking block and baffle plate.
Further, jacking force mechanism has the guide rod group of guiding jacking block rectilinear motion, and guide rod and the jacking block of guide rod group are fixed, and the other end passes baffle plate and the pilot hole corresponding with on baffle plate coordinates; Part guide rod is socketed described spring.Certainly, also each guide rod can put spring.
Further, clamp body offers through hole along short transverse, and the left side wall of through hole and right side wall are respectively as the first wall of cavity volume and the second wall, and the rear surface of clamp body offers the groove being communicated with through hole, baffle plate and clamp body are fixed and close described groove, and jacking block and spring are all installed in described groove; The top of through hole is provided with the block of its upper end open closed; The lower surface of block and the upper surface matched in clearance of jacking block.
Further, there is chamfering the lower end of jacking block.The existence of chamfering enables add-on parts enter between jacking block and the 3rd wall.
Body element in use, is first fixed on work top by the utility model, and the cavity volume of clamp body is just to body element needing the position of welding add-on parts.The vertical arm of the add-on parts at right angle inserted between jacking block and the 3rd wall, now spring is compressed, and under the restoring force effect of spring, jacking block pushes against add-on parts again.Starting elevating mechanism makes clamp body move to primary importance, and now accessory part arrives assigned address, add-on parts can be welded in body element.After spot welding completes, elevating mechanism resets, and the power of spring is less than the adhesive force after welding, and clamp body departs from add-on parts and resets to the second place.Take off the finished product after welding, prepare to weld next time.
The utility model utilizes clamp body to clamp the add-on parts of small size, by determining that the relative position of clamp body and body element reaches the object of the relative position determining add-on parts and body element; Set and Positioning is reliable, and the position dimension of add-on parts and body element is easily regulated.During welding, clamp body location add-on parts, is convenient to welding operation.The utility model has the dimensional accuracy that can improve the rear product of welding, improves the advantage of yield rate.The add-on parts that the utility model solves small size is difficult to the difficulty of locating.
