Description
Technical field
The utility model relates to a kind of welding tooling of handpiece of scraper conveyer frame.
Background technology
The headstock of drag conveyor comprises the front and back connecting plate be welded and fixed between left side plate of the spaced left side plate in left and right and time interval.Headstock is to be placed on by front and back connecting plate between left side plate and to be fixedly clamped by left side plate by fixture when welding, simultaneously, in left side plate, between the connecting plate of front and back, also place one piece of gripper shoe deform by the chucking power effect of fixture to avoid left side plate, again this gripper shoe is taken out after left side plate and front and back connecting plate spot welding are fixed.But in welding process left side plate can because of welding produce heat and deform, cause gripper shoe tightly to be clamped by left side plate and be difficult to take out, gripper shoe can only be pounded out with sledgehammer by workman, not only wastes time and energy, and easily causes gripper shoe to be pounded distortion and cannot continue to use.
Utility model content
The purpose of this utility model is: provide a kind of headstock spot welding mould, to solve in the current bonding machine headstock process problem of taking out gripper shoe and wasting time and energy.
The technical solution of the utility model is: a kind of headstock spot welding mould, comprise spaced two pairs of support bar group up and down, two support bars in often pair of support bar group are articulated and connected respectively by hinge axis, the Stop structure that mutual block coordinates when this two support bar is in same straight line is provided with between two support bars in often pair of support bar group, each support bar in often pair of support bar group is provided with back-up block for being supported on headstock left side plate inwall away from its hinge the tip of the axis respectively by hinge, the distance that in these two pairs of support bar group, each support bar supports end face by its hinge axis to respective support block is equal, the spacing between corresponding headstock side plate is greater than by its hinge axis to the Distance geometry of respective support block end face between two support bars be hinged, pair of parallel setting is hingedly connected with respectively between two support bars up and down and the relative connecting rod of length at homonymy between these two pairs of support bar group, the hinge axis of the pair of support rods group above being positioned at is connected with pressing handle.
Described connecting rod is connected between hinge axis corresponding to each support bar and bearing pin.
The support end face of described each back-up block is respectively equipped with anti-slop serrations.
Headstock spot welding mould of the present utility model forms two parallelogram sturcutres by two pairs of support bar group being articulated and connected and the connecting rod be connected between two support bar group, during use, two support bar group are supported on the inwall of headstock left side plate by the back-up block that each support bar end is installed, namely by two pairs of support bar group, left side plate is strutted by pressing handle, thus the gripper shoe be placed on when can take out welding easily between headstock left side plate, this headstock spot welding mould structure is simple, easy to use, efficiently solve the defect that prior art exists.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model headstock spot welding mould specific embodiment.
Detailed description of the invention
The specific embodiment of headstock spot welding mould of the present utility model as shown in Figure 1, this frock comprises spaced by a pair upper support bar 10 up and down, 11 composition upper support bar groups 1 and by a pair lower support bar 20, the lower support bar group 2 of 21 compositions, two upper support bars 10 in upper support bar group 1, one end of 11 is articulated and connected by upper hinge axle 12, two lower support bars 20 in lower support bar group 2, one end of 21 is articulated and connected by lower hinge axis 22, at two upper support bars 10, 11 away from the end of upper hinge axle 12 and two lower support bars 20, 21 descend the end of hinge axis 22 to be all provided with for being supported on the corresponding left side plate 100 of headstock by the corresponding hinge arranged away from it, back-up block 7 on 200 inner surfaces.Two upper support bars 10,11 of upper support bar group 1 to support by its upper hinge axle 12 distance that the distance of end face and two lower support bars 20,21 in lower support bar group 2 support end face by its lower hinge axis 22 to corresponding back-up block 7 to corresponding back-up block 7 equal, and two upper support bars 10,11 support by its upper hinge axle 12 to corresponding back-up block 7 Distance geometry that the Distance geometry of end face and two lower support bars 20,21 support end face by its lower hinge axis 22 to corresponding back-up block 7 is all greater than spacing between headstock left side plate 100,200.
Between upper support bar group 1 and lower support bar group 2, left connecting rod 3 is connected with between the upper support bar 10 and the bearing pin of lower support bar 20 of phase the same side, right connecting rod 4 is connected with between the upper support bar 11 and the bearing pin of lower support bar 21 of opposite side, simultaneously, intermediate connecting rod 5 is connected with between the upper hinge axle 12 and the lower hinge axis 22 of lower support bar group 2 of upper support bar group 1, left connecting rod 3, the length of right connecting rod 4 and intermediate connecting rod 5 is equal, thus between upper support bar group 1 and lower support bar group 2, surround two parallel-crank mechanisms, the hinge axis 12 of upper support bar group 1 is fixed with pressing handle 6, this pressing handle 6 is wholely set with intermediate connecting rod 5.The Stop structure that mutual block coordinates when two support bars with group are in same straight line is also respectively equipped with between two upper support bars 10,11 of upper support bar group 1 and between two lower support bars 20,21 of lower support bar group 2, in the present embodiment, this Stop structure is the upper block 13 being separately positioned on upper support bar 10 and the lower block 23 be fixed on lower support bar 20.Upper block 13 coordinates with the upper surface block of upper support bar 11 when two upper support bars 10,11 turn to and are in straight line position, lower block 23 coordinates with the upper surface block of lower support bar 21 when two lower support bars 20,21 turn to and are in same linear position, thus can avoid losing supporting role when using this welding tooling because rotation overdoes.
When the left side plate of headstock and after before and after it, connecting plate (depending on not going out in figure) is welded and fixed, this headstock spot welding mould is positioned between the left side plate of headstock, each back-up block is supported end face respectively by it to be supported on the inner surface of corresponding left side plate, then firmly pressing handle is promoted downwards, thus by upper and lower two support bar group, the left side plate of headstock is backed down, be positioned over the gripper shoe between left side plate before easily taking out welding.
