Description

Bogie welding and clamping device and clamping method
Technical field
The present invention relates to welding clamping apparatus technical field, especially a kind of bogie welding and clamping device and clamping method.
Background technology
When assembly welding radial steering framework, as its weld size of important spare part of framework, upper and lower guide beam bearing must ensure that enough welding precisions are follow-up and radial direction mechanism could be installed smoothly, tradition assembling is that overhead traveling crane or manpower will be welded architecturally after upper and lower guide beam lifting, each upper and lower guide beam bearing weighs more than 100 kilogram, this makes the weld size precision of upper and lower guide beam bearing be difficult to ensure, call overhead traveling crane or manpower in tradition assembly welding process upper and lower guide beam bearing to be welded on framework and to be both difficult to ensure weld size precision, waste energy, also there is potential safety hazard.
Summary of the invention
In order to overcome existing above-mentioned deficiency, the invention provides a kind of bogie welding and clamping device and clamping method.
The technical solution adopted for the present invention to solve the technical problems is: a kind of bogie welding and clamping device, comprise base, mainboard, upper fixture, lower clamp, fastening bolt, bolt, described base is welded on bottom mainboard, mainboard side is toothed surface, toothed surface is provided with four longitudinal register grooves, mainboard toothed surface top is provided with two upper fixtures, mainboard toothed surface bottom is provided with two lower clamps, fixture is fixed in longitudinal register groove by the bolt at upper and lower two ends, and fixture is provided with fastening bolt.
According to another embodiment of the invention, comprise a kind of clamping method of bogie welding and clamping device according to claim 1 further, clamping step is:
A. according to the size of the upper and lower guide beam bearing of bogie, upper fixture and lower clamp are located its lateral dimension by four longitudinal register grooves;
B. again according to the lengthwise position of upper and lower guide beam bearing, the longitudinal size of upper fixture and lower clamp is located by toothed surface;
C. subsequently bolt is screwed;
D. upper and lower guide beam bearing is respectively charged into upper fixture and lower clamp;
E., after guaranteeing between bearing and fixture laminating completely, fastening bolt is screwed;
F. the bearing of guide beam up and down of having good positioning is moved to framework correct position by this device;
G. after base and framework are fixed, by bearing welding architecturally.
The invention has the beneficial effects as follows, structure is simple, easy to operate, and working stability is reliable, improves welding precision, ensure that the weld size precision of upper and lower guide beam bearing, improve the production efficiency of framework, meet need of production, save manpower and cost.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is perspective view of the present invention.
Fig. 2 is right view of the present invention.
In figure, 1. bases, 2. mainboard, 3. go up fixture, 4. lower clamp, 5. fastening bolt, 6. bolt, 7. longitudinal register groove, 8. toothed surface.
Detailed description of the invention
As shown in Figure 1, 2, a kind of bogie welding and clamping device, comprise base 1, mainboard 2, upper fixture 3, lower clamp 4, fastening bolt 5, bolt 6, described base 1 is welded on bottom mainboard 2, and mainboard 2 side is toothed surface 8, and toothed surface 8 is provided with four longitudinal register grooves 7, mainboard 2 toothed surface 8 top is provided with two upper fixtures 3, mainboard 2 toothed surface 8 bottom is provided with two lower clamps 4, and fixture is fixed in longitudinal register groove 7 by the bolt 6 at upper and lower two ends, and fixture is provided with fastening bolt 5.
Longitudinal register groove 7 ensures the horizontal and vertical location dimension of two fixtures, and upper lower clamp and fastening bolt 5 are by Workpiece fixing, and the function of bolt 6 is fastening upper lower clamps.Before using, according to the size of upper and lower guide beam bearing, upper lower clamp is located its lateral dimension by four longitudinal register grooves 7, again according to the lengthwise position of upper and lower guide beam bearing, longitudinal figure paper size of upper lower clamp is located by toothed surface 8, subsequently bolt 6 is screwed, after on determining, lower clamp is had good positioning, guarantee that two upper fixtures 3 or lower clamp 4 are in same level, during use, upper and lower guide beam bearing is respectively charged into upper lower clamp, after guaranteeing between strutbeam and fixture laminating completely, fastening bolt 5 is screwed, ensure between bogie bearing and fixture without relative motion, finally the bearing of guide beam up and down of having good positioning is moved to framework correct position by this device, after fixing to base 1 and framework, guarantee that the relative position of upper and lower guide beam bearing and framework meets drawing requirement, by bearing welding architecturally.
Bogie welding and clamping device after improvement, easy to operate, working stability is reliable, improves welding precision, ensure that the weld size precision of upper and lower guide beam bearing, improve the production efficiency of framework, meet need of production, save manpower and cost.
