Abstract
The utility model discloses a kind of oil cylinder stepped hole class cylinder barrel bottom welding toolings, belong to hydraulic cylinder tooling technical field.It solve traditional stepped hole class cylinder barrel bottom earrings hole in the prior art have ladder and length it is longer caused by location difficulty, do not allow the defect of easy to operate, poor welding quality, low efficiency, large labor intensity.Its main structure includes vertical plate, block, upper positioning core axle, lower positioning core axle and bottom plate, and the block is connect with vertical plate, and bottom plate is connect with vertical plate, and the lower positioning core axle is fixed on bottom plate, and the upper positioning core axle is slideably coupled with block.The utility model is mainly used for the welding at oil cylinder stepped hole class cylinder barrel bottom.
Description
Technical field:
The utility model belongs to hydraulic cylinder tooling technical field, specifically, more particularly to a kind of oil cylinder stepped hole class
Cylinder barrel bottom welding tooling.
Background technique:
Cylinder barrel bottom is the main component of hydraulic cylinder, plays connection guiding role.Cylinder barrel back welding connects at present, is half assembly of cylinder barrel
It welds again after the completion, bent plate is used when welding, is positioned with cylinder barrel bottom pin shaft hole, but due to stepped hole class cylinder barrel bottom earrings hole
There is ladder and length is longer causes location difficulty, do not allow easy to operate, is not only difficult to ensure welding quality, and inefficiency, very
Inconvenience, while large labor intensity, welding is just more difficult when especially batch production or workpiece size are larger.
Summary of the invention:
In order to solve traditional stepped hole class cylinder barrel bottom earrings hole in the prior art have ladder and length it is longer caused by it is fixed
Position is difficult, does not allow the shortcomings that easy to operate, poor welding quality, low efficiency, large labor intensity, and the utility model provides a kind of difference
In the oil cylinder stepped hole class cylinder barrel bottom welding tooling of the prior art, Product jointing quality is improved, and work easy to operate
Make high-efficient, reduces the labor intensity of worker.
To achieve the goals above, the utility model adopts the following technical solutions realization:
A kind of oil cylinder stepped hole class cylinder barrel bottom welding tooling, including vertical plate, block, upper positioning core axle, lower positioning core axle and
Bottom plate, the block are connect with vertical plate, and bottom plate is connect with vertical plate, and the lower positioning core axle is fixed on bottom plate, the upper positioning
Mandrel is slideably coupled with block.
Further, the side of the vertical plate is additionally provided with clamping mandrel.
Further, the clamping mandrel, upper positioning core axle and lower positioning core axle are multi-diameter shaft.
Compared with prior art, the utility model has the beneficial effects that
1, using two kinds of positioning methods, bottom positions inner hole using lower positioning core axle, and top is positioned using block and positioned
Mandrel, i.e. Dual positioning keep positioning accuracy high, solve the problems, such as that the welding geometric tolerance at stepped hole class cylinder barrel bottom is overproof, mention
High Product jointing quality, guarantees geometric tolerance after Product jointing；
2, manual hand manipulation, it is easy to operate, meet ergonomics, improves work efficiency；
3, the cylinder barrel back welding that the utility model is suitable for different product connects, and saves mould replacing time, while reducing worker
Labor intensity.
Detailed description of the invention:
Fig. 1 is the main view of the utility model；
Fig. 2 is the top view of the utility model；
Fig. 3 is the left view of the utility model；
Fig. 4 is the structural schematic diagram that the utility model is installed and used.
In figure: 1, clamping mandrel；2, vertical plate；3, screw I；4, block；5, upper positioning core axle；6, lower positioning core axle；7, bottom
Plate；8, screw II；9, workpiece；10, small axis；11, big axis.
Specific embodiment:
Below by specific embodiment and in conjunction with attached drawing, the utility model is described in further detail.
Embodiment 1:
As shown in Figure 1-3, a kind of oil cylinder stepped hole class cylinder barrel bottom welding tooling, including vertical plate 2, block 4, upper positioning core axle
5, lower positioning core axle 6 and bottom plate 7, the block 4 are fixedly connected by screw I 3 with vertical plate 2, and bottom plate 7 is by screw II 8 and stands
Plate 2 connects, and the lower positioning core axle 6 is fixed by screws on bottom plate 7, and the upper positioning core axle 5 is slideably matched with block 4
Close installation；Upper positioning core axle 5 is that slideably, workpiece 9 is adjustable in a certain range after installing, due to upper positioning core axle 5
For multi-diameter shaft, therefore following small axis 10 is placed on 9 the inside of workpiece, cooperates with workpiece 9, block 4 be machined at one circular arc just with
The outer surface of the big axis 11 of upper positioning core axle 5 is coupled；The small axis 10 and big axis 11 are structure as a whole, and it is fixed to collectively form
Position mandrel 5.
Embodiment 2:
A kind of oil cylinder stepped hole class cylinder barrel bottom welding tooling, the side of the vertical plate 2 is additionally provided with clamping mandrel 1, clamping core
Axis 1 is first passed through to be welded on vertical plate 2 again with after the hole progress transition fit on vertical plate 2.
The clamping mandrel 1, upper positioning core axle 5 and lower positioning core axle 6 are multi-diameter shaft.Other parts and 1 phase of embodiment
Together.
The working principle that the utility model is installed and used are as follows:
1, quickly mold changing: clamping mandrel 1 is clamped with chuck, adjusts frock level；(i.e. according to stepped hole class cylinder barrel bottom to be welded
Workpiece 9) pin shaft hole internal diameter chooses the upper positioning core axle 5 and lower positioning core axle 6 that match, with screw by lower positioning core axle 6
It is fixed on bottom plate 7.
2, operating procedure: stepped hole class cylinder barrel bottom finished product after processing is completed, cylinder barrel bottom is mounted on the utility model, bottom
Portion uses lower 6 positioning of bottom stepped hole of positioning core axle, and top stepped hole is positioned using upper positioning core axle 5, and will be upper fixed with block 4
Position mandrel 5 clamps, and preventing from loosening in welding process influences welding quality；After be welded after the completion of 9 clamping of workpiece；Replace product
Positioning core axle 5 and lower positioning core axle 6 are only needed to change when type, are just able to satisfy the weldering at various sizes of stepped hole class cylinder barrel bottom
It connects.
