Description

A kind of polishing clamp of ratchet wrench head

Technical field

Technical field of hardware is the utility model is related to, specially a kind of polishing clamp of ratchet wrench head.

Background technology

Spanner is a kind of conventional installation and extracting tool.Bolt, screw, nut and other spiral shells are twisted using lever principle Line tightly holds the opening of bolt or nut or the hand tools of trepanning firmware.Spanner is generally formed with clamp holder in the one or both ends of shank Portion applies external force shank and applies external force, and the opening or sets of holes of bolt or nut are held with regard to that can twist bolt or nut.Along spiral shell during use Line direction of rotation applies external force in shank, with regard to that can twist bolt or nut.

A kind of existing ratchet spanner, is also monkey wrench, and its structure is as shown in figure 1, including spanner handle 30 and driving end 31, both are be hinged.Using such a spanner, it can rotate backward, it is not necessary to adjust spanner rotational angle after exiting the fastener of effect Again it is caught in, it functions as ratchet spanner, widely applicable.

The outline 311 of driving end 31 is multi-section circular arc formula structure, and its Internal periphery 312 is the polygon structure to connect.In life During production, during the driving end 31 of such a spanner is processed, hook typically uses carbon structure steel making, and first forging and stamping are rolled Hook embryo shape is made, then by metal cutting process such as milling, polishings, is finally heat-treated.

And at present to more than the polishing grinding of driving end 31 using manual progress, particularly in the foreign steamer to driving end 31 The sanding and polishing of exterior feature 311, because surface is multi-section circular arc formula structure, the not only low production efficiency, and easily causing in polishing Waste product is processed, misoperation is also easier to cause injury, potential safety hazard be present.Thus, the outline 311 of urgent need driving end 31 Polishing grinding device, it is while efficient in the convenient mounting and clamping of polishing grinding, processing in order to ensure, it is also desirable to suitable fixture.

Utility model content

The purpose of this utility model is to be directed to problem above, there is provided a kind of polishing clamp of ratchet wrench head, for coordinating Polishing machine polishes, and its convenient mounting and clamping, processing are efficient.

To realize object above, the technical solution adopted in the utility model is：A kind of polishing clamp of ratchet wrench head, bag Include axis（32）, the axis（32）Section is and driving end（31）Internal periphery（312）The polygonized structure being engaged；The card Axle（32）On be provided with it is multiple by demarcation strip（33）The workpiece position being separated（38）, the demarcation strip（33）Along axis（32）Axle To being uniformly arranged；Axis（32）Both ends of the surface are provided with the square shaft being connected with transmission device（36）；The workpiece position（38）Middle setting There is dismountable driving end mould（34）.

Further, the driving end mould（34）The 5-8 station in interval is uniformly arranged.

Further, driving end mould（34）With axis（32）Connected using sunk screw；Changed after convenient abrasion.

Further, the axis（32）Workpiece position（38）Surface is provided with anti-slip veins.

Further, the demarcation strip（33）For rectangle, and rectangle corner is no more than driving end（31）Outline （311）.

The beneficial effects of the utility model：The utility model provides a kind of polishing clamp of ratchet wrench head, for Polishing machine polishing is closed, its convenient mounting and clamping, processing are efficient；Meanwhile the driving end mould consistent with driving end standard component is provided with, have Effect prevents transition of polishing.
