Description
Technical field
The utility model relates to a kind of spanner, relates in particular to the spanner that a kind of fixedly screw tap is used.
Background technology
In auto manufacturing, on some vehicle body punching parts, often can be used for follow-up general assembly Assembly part by welded nut at present.When nut and Plate Welding, occasional occurs that the hole decentraction on nut bore and steel plate even hides the situation in hole; When postorder carries out gas shielded arc welding welding, some splashes that produce in welding process can be bonded on the screw thread of nut.Both of these case all can cause bolt to be not easy to throw into nut, thereby affects the Assembly of the parts of general assembly.So generally need to carry out manual tapping to nut bore with screw tap, to guarantee bolt, throw nut into.
In prior art, generally in screw tap rear end, perpendicular to screw tap, axially weld an iron staff, the handle that rotates screw tap during as manual tapping is used.Because the nut bore of different size needs the screw tap of corresponding different size, the iron staff and each screw tap will be burn-on like this, before using like this, to first once weld, use comparatively inconvenience, and because iron staff is fixedly connected with screw tap, can not secondary utilization, will cause the waste of screw tap and iron staff, improved production cost.Therefore need a kind of can adaptation and the fixing spanner of the screw tap of different size.
Utility model content
The iron staff of the corresponding welding of a screw tap that the utility model exists in order to overcome prior art, causes production cost waste, and uses the comparatively deficiency of inconvenience, provide a kind of can adapt to and fixedly different size screw tap, use spanner comparatively easily.To achieve these goals, the utility model is by the following technical solutions:
The spanner that a kind of fixedly screw tap is used, comprise left handle in a tubular form, right handles, contiguous block, compact heap, described contiguous block is strip, its upper and lower both ends of the surface are plane, contiguous block is provided with square hole between upper and lower end face, contiguous block right-hand member is provided with the manhole that is through to square hole perpendicular to square hole opening direction, described through hole internal diameter is greater than right handles cross section external diameter, contiguous block right-hand member via openings place axially extends outwardly and is installed with right sleeve pipe along through hole, contiguous block left end corresponding position is installed with the left sleeve pipe being symmetric with right sleeve pipe, left handle, right handles respectively with left sleeve pipe, right casing threads connects, it is block that described compact heap is, compact heap right-hand member and right handles left end removably connect, compact heap and square hole matched in clearance.
The utility model, in order to overcome an iron staff of the corresponding welding of screw tap of prior art, is used the comparatively deficiency of inconvenience.Compact heap slides in contiguous block square hole, and for being fixed screw tap with square hole, left handle, right handles are connected and are used for forming spanner with the left sleeve pipe of contiguous block, right casing threads respectively, rotary spanner while facilitating tapping.During use, first compact heap is put into the square hole of contiguous block, right handles is stretched into right sleeve pipe and be threaded with it, again right handles is screwed in to contiguous block and its left end is entered in square hole, right handles left end is connected with compact heap, the stiff end of the screw tap that will use is again placed between the square hole left end of compact heap left end and contiguous block, continuation screws in contiguous block by right handles, right handles drives compact heap to draw close to square hole left end, thereby screw tap is fixed in contiguous block, again left handle is inserted in the left sleeve pipe of contiguous block opposite side, forms windeisen.When needs are changed screw tap, only right handles need to be screwed out to contiguous block, right handles drives compact heap to move right like this, can take out screw tap, after replacing, as long as adjust right handles, can drive compact heap that different screw taps are fixed in contiguous block, very easy to use, therefore realized the purpose of this utility model.
As preferably, described right handles left end is installed with connector, described connector comprises two circular braces that be arranged in parallel, between brace, be vertically installed with joint pin, described compact heap right side is inwardly provided with connecting hole, described connecting hole internal diameter and brace external diameter are suitable, and compact heap also comprises connecting pin, and compact heap is provided with pin hole.Compact heap can removably connect by connecting pin with connector like this, simultaneously in right handles, rotates and adjusts compact heap between square hole left end during distance, and compact heap can not follow right handles to rotate together, comparatively laborsaving, and use more for convenience.
As preferably, described pin hole is perpendicular to the upper and lower end face of compact heap, the formed column cavity of pin hole middle part overlaps with connecting hole, and when the connector of right handles stretches into the connecting hole of compact heap, connecting pin links together compact heap and right handles through pin hole.While guaranteeing that like this connecting pin can enter compact heap connecting hole at the connector of right handles, be stuck between connector two braces, bonding strength is better like this, is difficult for when right handles is rotated, and compact heap and connector depart from, and uses more for convenience.
As preferably, described square hole extends left and is provided with delthyrium, and the base length in described delthyrium cross section is identical with square hole width, and drift angle is between 30 degree to 60 degree.The setting of delthyrium is convenient to the foursquare stiff end of screw tap to snap in the drift angle of delthyrium, makes the constant intensity of screw tap better, is more easy to use.
As preferably, described compact heap left end is provided with triangular prism shape projection integratedly, and described convex cross section and delthyrium cross sectional shape are suitable.The projection of compact heap left end and delthyrium cross section are suitable, like this compact heap and square hole left end coordinate distance less, be convenient to solve the problem when using the less screw tap of some sizes, be more easy to use.
As preferably, described compact heap projection left end is axially arranged with draw-in groove along it, and described draw-in groove cross section is triangle, and draw-in groove cross section drift angle is identical with delthyrium cross section drift angle angle.The setting of draw-in groove is convenient to match with delthyrium, and its two ends of the foursquare stiff end of screw tap are snapped into respectively in draw-in groove and delthyrium, has further increased the constant intensity of screw tap, makes mounted screw tap more be easy to use.
As preferably, forward and backward of described contiguous block is arc surface.Because the forward and backward face of spanner is the place of wearing and tearing the most easily to occur in producing, be therefore made as arc surface, reduce wear on the one hand, another convenient safety that has also increased operating personnel, is not easy to be scratched by the corner of spanner.
As preferably, before described contiguous block and between left and right, after and left and right between intersection be equipped with fillet.The deterioration that is arranged so that spanner of fillet further reduces, and makes operating personnel safer simultaneously, can not scratched by the corner of spanner.
As preferably, described left handle, right handles outwardly one end are respectively equipped with anti-skidding lines.The spanner use that is arranged so that of anti-skidding lines is difficult for skidding, and is more easy to use.
As preferably, described left handle, right handles are hollow shape.Left handle, the right handles of hollow shape have reduced production cost, make instrument more light simultaneously.
The utility model has the advantage of: can adapt to and fixing different size screw tap, use more for convenience.
