Abstract
The utility model relates to a drilling cover die, in particular to a die for conducting drilling operation on the steel structure workpieces under the on-site construction conditions. The die is used for drilling holes for large-scale steel structure workpieces and non-standard equipment; and the die adopts the technical scheme that a template with a periphery being 30 mm larger than a workpiece is manufactured according to the size of shape and position of holes on the workpiece, a plurality of guide sleeves are embedded on the template and in the positions corresponding to the holes on the workpiece, a nut connected with a positioning bolt through threads is connected with the edge of the template by welding, the workpiece to be drilled with holes is positioned on the lower side of the template and in contact with the positioning bolt, the positions of the holes on the workpiece are guaranteed by adjusting the positioning bolt, and a pressure plate is positioned on the template and connected with a working table of a drilling machine through a pressure bolt; the diameter of an inner hole of the cover die is 0.15-0.2 mm larger than the aperture of the workpiece; and a drill bit is accurately positioned through the guide sleeve during the drilling process, so as to effectively ensure the drilling precision and improve the working efficiency.
Description
Technical field
The utility model relates to a kind of boring cover die, particularly at the scene under the execution conditions, steel knot workpiece is carried out the mould of bore operation.
Background technology
At present under the condition that unit in charge of construction makes at the scene, the boring majority of big shaped steel knot workpiece and non-standard equipment is taked on-the-spot line, is beaten the simple process of dotting punch, boring, often can not guarantee construction quality, cause do over again and also efficient low.
Summary of the invention
In order to overcome the above problems, the utility model provides a kind of easy to operate boring cover die.
The utility model is made of template, guide pin bushing, bolt, pressing plate and hold-down bolt, it is characterized in that: a plurality of guide pin bushings are embedded on the same template, the guide pin bushing diameter of bore is greater than 0.15～0.2 millimeter in workpiece aperture, connect with the nut and the weldering of template limit of bolt spiral marking connection, workpiece is positioned at the template downside and contacts with bolt, and pressing plate is positioned at above the template and connects by hold-down bolt and Drilling machines bench.Guide pin bushing adopts No. 45 steel or the 40Cr steel is made and through Quenching Treatment.
The technical scheme that its technical problem that solves the utility model adopts is: the morpheme size of pressing hole on the workpiece is made all around greater than the about 30 millimeters template of workpiece, a plurality of guide pin bushings are embedded in position corresponding with workpiece hole on the template, connect with the nut and the weldering of template limit of bolt spiral marking connection, the workpiece of desire boring is positioned at the template downside and contacts with bolt, by adjusting the position that bolt guarantees hole on the workpiece, pressing plate is positioned at above the template and connects by hold-down bolt and Drilling machines bench.The cover die diameter of bore is greater than 0.15～0.2 millimeter in workpiece aperture.Drill bit is accurately located by guide pin bushing during boring, thereby effectively guarantees borehole accuracy, improve work efficiency.
The beneficial effects of the utility model are, the workpiece many to the quantity in same specification and hole, as steel crane beam keep plate and steel roof truss connecting plate etc. Workpiece boring, can effectively guarantee borehole accuracy, improve work efficiency, guarantee the pitch-row deviation≤0.1mm of boring, position degree deviation≤0.1mm guarantees the interchangeability of part processing, and can overcome the problem of construction equipment deficiency under the condition of field fabrication fully.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural front view of the present utility model.
Fig. 2 is a structure vertical view of the present utility model.
Fig. 3 is expanded application figure of the present utility model.
The specific embodiment
From Fig. 1 and Fig. 2 as can be seen, the utility model is made of template 1, guide pin bushing 2, pressing plate 3, hold-down bolt 4, bolt 5.Guide pin bushing 2 is embedded on the same template 1, the guide pin bushing diameter of bore is greater than 0.15～0.2 millimeter in workpiece aperture, connect with the nut of bolt 5 spiral marking connections and the limit weldering of template 1, workpiece 6 is positioned at the template downside and contacts 5 with bolt, and pressing plate 3 is positioned at above the template 1 and connects by hold-down bolt 4 and Drilling machines bench 7.
During use workpiece 6 is placed on the Drilling machines bench 7, it is consistent with the workpiece hole center again the bolt on the template 15 to be required to adjust to the guide pin bushing center according to the workpiece drawing; Be placed on template 1 on the workpiece 6 and the edge of workpiece is contacted with bolt 5, template 1 and workpiece 6 are pressed on the Drilling machines bench 7, drill bit is inserted guide pin bushing 2 just can accurately hole workpiece with pressing plate 3 and hold-down bolt 4.
Fig. 3 is that expansion of the present utility model is used.When the hole count of workpiece 6 is many and pitch-row is identical and be that bars such as crane girder upper flange are holed.On workpiece, get out first group of hole, insert alignment pin 8 in the hole of on guide pin bushing 2 and workpiece 6, having bored again, just can get out next group hole with template.Roller rack 9 is moving and aim at and design for the ease of the string of part 5.
Claims (2)
1. boring cover die, comprise template, guide pin bushing, bolt, pressing plate and hold-down bolt, it is characterized in that: a plurality of guide pin bushings are embedded on the same template, the guide pin bushing diameter of bore is greater than 0.15～0.2 millimeter in workpiece aperture, connect with the nut and the weldering of template limit of bolt spiral marking connection, workpiece is positioned at the template downside and contacts with bolt, and pressing plate is positioned at above the template and connects by hold-down bolt and Drilling machines bench.
