CN205289850U - Small -size axle type part quick drilling frock - Google Patents

Abstract

The utility model belongs to the field of machining, concretely relates to small -size axle type part quick drilling frock for location and clamping during drilling. Because of the assembly demand, all there are insurable spot facing work, fixing behind the mainly used component assembly on most small -size axle type part. At present, the processing of this type of part relies on the pincers worker to delimit bit line, drilling processing more basically. Its shortcoming is: it is first: all need delimit the bit line on each part, if it is big in batches, the parts machining support time overlength, the second: when the first bit insures the spot facing work, owing to drill, do not have the guide with fixed on the disc, the drill bit skids when the contact part easily, causes incline about the insurable hole of processing, the decentraction, lead to twisting the assembly part after, the unable assembly of safety catch, work efficiency also hangs down, the third: operation workman intensity of labour is big. The utility model provides a quick change clamping, swift convenience pinpoints, operates, intensity of labour is little, work efficiency is high, the operation is safe small -size axle type part quick drilling fixing mold insert frock.

Description

A kind of small shafts part Quick drilling tool

Technical field

This utility model belongs to field of machining, is specifically related to a kind of small shafts part Rapid tooling, is used for location when holing and clamping.

Background technology

Because of assembling demand, most small shafts part all there is insurance hole machined, be mainly used in fixing after part assembling. At present, the processing of this type of part, substantially rely on pincers worker to delimit bit line then Drilling operation. Its shortcoming is: first: all need on each part to delimit bit line, if batch is big, part processing is long for non-cutting time; Second: when little drill bit carries out insurance hole machined, owing to holing on disc, without guiding and fixing, drill bit is when contacting part, easily skid, cause the upper and lower deflection in insurance hole of processing, not with one heart, after causing being screwed into Assembly part, safety plug cannot assemble, and work efficiency is also low; 3rd: operator's labor intensity is big.

Utility model content

Technical problem to be solved in the utility model is: propose a kind of quick change clamping, be accurately positioned, swift and convenient to operate, labor intensity is little, work efficiency is high, the small shafts part rapid drilling positioning and clamping frock of operation safety.

The technical solution of the utility model is: a kind of small shafts part Quick drilling tool, by base, left support bar, right support bar, installs screw, rotating clamp, tightens screw and assists cushion block to form; Wherein,

Base has the stepped hole inserting axial workpiece in the middle part of upper surface, and the arranged on left and right sides in upper surface has the screwed hole installing described left support bar and right support bar, has the through hole of drill guide in front; Left support bar is integral type structure, is threaded in its lower end, and upper end is with axle journal; Right support bar includes installing screw and swivel nut, and there are screwed hole and bottom in swivel nut top with external screw thread; Rotating clamp has screwed hole at middle part, at right-hand member, there is through hole, at left end, there is open hole, tighten the screw screwed hole through rotating clamp, and connect in end and auxiliary cushion block, the through hole installing screw traverse rotating clamp right-hand member is threadeded with the swivel nut of right support bar, the rotatable axle journal snapping in left support bar of rotating clamp.

The utility model has the advantages that: quick change clamping, be accurately positioned, swift and convenient to operate, labor intensity is little, work efficiency is high, operation safety. It was verified that after employing this utility model, work efficiency improves more than five times.

Detailed description of the invention

Below this utility model is described in further details:

Referring to Fig. 1, small shafts part rapid drilling positioning and clamping frock, it is characterised in that it is tightened screw 6 by base 1, left support bar 2, right support bar 3, installation screw 4 rotating clamp 5 and assisted cushion block 7 to form. Left support bar 2, right support bar 3 are arranged on base 1, further through rotating clamp 5 with tighten screw 6 and auxiliary cushion block 7 be connected.

Using method of the present utility model is: left support bar 2 and right support bar 3 are arranged on base 1, part loads base 1, rotating clamp one end is arranged on right support bar 3, after tightening screw 6 and assisting cushion block 7 to be arranged on rotating clamp, rotating rotating clamp, the other end is buckled on left support bar 2, screw is tightened again through rotation, drive auxiliary cushion block to move, hold out against part end face, retaining element.

When insuring hole by the guide hole processing on base, both decreased the time of scribing by bench worker, and by the guiding function of guide hole, it is to avoid drill slipping and deflection, it is ensured that the perpendicularity requirement of insurance hole and axis of workpiece, it is ensured that can reach with one heart after loading Assembly part.

Batch jobs: this frock uses simple to operate, part can realize quick-clamping, is accurately positioned, labor intensity is little, work efficiency is high, the stable and reliable product quality of processing; The batch machining of part can be met.

This utility model is compared with traditional processing method, and production efficiency significantly improves, solve small shafts part can the problem of quick location drilling clamping, reduce that operator's labor intensity is big, time-consuming problem of ruling. This utility model can carry out accurately and conveniently small shafts part can quick location drilling, while ensureing positioning precision, save part non-cutting time in a large number, efficiency is high, labor intensity is low, and when batch production, effect becomes apparent from.
