Description
Technical field:
The utility model relates to field of machining, are a kind of clamping works for the hole tapping of micro parts fine thread
Tool.
Background technique:
In pincers worker tapping, for Small Holes tapping, difficulty of processing itself is with regard to larger, and on micro parts
It is even more extremely difficult for Small Holes.Since design of part is small, and without available tooling, operator in tapping,
Can only a hand-held part, a hand-held screw tap processed, and be there is a problem of that part can not be held steady and is held jail, leads to screw tap and bottom outlet
Can not good centering, easily cause tap deflection, screw tap fracture and other issues influences rear end assembly, and tapping low efficiency,
Large labor intensity, it is difficult to adapt to the production requirement of mass.
Summary of the invention
The utility model is directed to the deficiency of existing processing method, provides a kind of for the hole tapping of micro parts fine thread
Clamping tool, existing problems, it is tiny to be substantially improved micro parts when can effectively avoid original processing method hand-held
The quality and efficiency of threaded hole.
The technical solution adopted in the utility model is a kind of clamping tool for the hole tapping of micro parts fine thread,
It is characterised by comprising: opening mould 1, screw 2 and nut 3, the opening mould 1 is axial to have waist typed through hole 6, and top is opened
There is narrow slot 8, several Set and Positioning holes 4 is evenly equipped with along 8 direction of narrow slot, outside the structure and part in the Set and Positioning hole 4
Shape structure is consistent, is laterally step surface a9 and step surface b 10 wide at the top and narrow at the bottom, uniformly distributed several perforation unthreaded holes on step surface a 9
11, the screw 2 is soket head cap screw, passes through and penetrates through unthreaded hole 11 on the opening mould 1, matches with the nut 3.
Optimal 2 type of screw is soket head cap screw.
The quantity in the Set and Positioning hole 4 is determined by the distance between 1 length of opening mould and adjacent Set and Positioning hole 4.
The quantity of the perforation unthreaded hole 11 is determined by the length of opening mould 1.
8 direction of narrow slot is evenly equipped with unthreaded hole a 5 and unthreaded hole b 7, unthreaded hole a 5, unthreaded hole b 7 and 4 three hole of Set and Positioning hole
Coaxially.
Compared with original processing method, the utility model is convenient for mounting and clamping, easy to operate, when effectively eliminating hand-held part tapping
Existing free molecular flow keeps whole process stable, reliable, and existing quality risk, is obviously improved during evasive action
The processing quality of part detains screw thread by borrowing tapping machine pre-tapped 2 to 3, makes tapping process become more easily to operate, while one
Secondary processing more than one piece realizes processed in batches, significantly the times such as shortening clamping, adjustment, greatly improves processing efficiency.

Specific embodiment
It for better implementation the utility model, elaborates, asks to the utility model with reference to the accompanying drawings of the specification
Refering to Figure of description 1~5.
A kind of clamping tool for the hole tapping of micro parts fine thread, comprising: opening mould 1, screw 2 and nut
3。
The opening mould 1 is axial to have waist typed through hole 6, and top is provided with narrow slot 8, is evenly equipped with along 8 direction of narrow slot
Several Set and Positioning holes 4, unthreaded hole a 5 and unthreaded hole b 7, and three holes are coaxial, the structure and External Shape knot in the Set and Positioning hole 4
Structure is consistent, and quantity is determined by the distance between 1 length of opening mould and adjacent Set and Positioning hole 4, is laterally platform wide at the top and narrow at the bottom
Terrace a 9 and step surface b 10, along axial uniformly distributed several perforation unthreaded holes 11, the number of the perforation unthreaded hole 11 on step surface a 9
Amount is determined that the screw 2 is soket head cap screw by the length of opening mould 1, is passed through and is penetrated through unthreaded hole 11 on the opening mould 1,
It is matched with the nut 3.
During clamping tool designs and produces, according to External Shape structure size, the structure in Set and Positioning hole 4 is determined
Size determines the cross sectional dimensions for the mould 1 that is open, the size of waist typed through hole 6 and narrow slot 8 according to the size in Set and Positioning hole 4
Size determines the axial dimension of opening mould 1 according to the spacing between the quantity and adjacent parts that need to once process part, according to opening
The height of the axial dimension of mouthful mould 1, cross sectional dimensions and step surface a 9 determines size, quantity and the spacing of perforation unthreaded hole 11,
The specification and quantity of screw 2, nut 3 are determined according to the size and number of perforation unthreaded hole 11.Unthreaded hole a 5 and unthreaded hole b 7 and clamping
Location hole 4 is coaxial, and when part easy to disassemble ejects it from below.
In clamping tool use process, opening mould 1 is placed horizontally in small-sized vice jaw, and is applied centainly
Pretightning force (guarantee mould not in vice jaw easily play), part is put into one by one in each Set and Positioning hole 4, it is ensured that
Each part pressing is adjacent to, and tightens vice, is made mould opening tightening, is kept each parts fixation firm, vice is placed in small-sized tapping machine
On, 2~3 are successively drawn on each part and buckles screw thread, after the completion removes opening mould 1 from vice, it will with screw 2 and nut 3
Mould opening tightening, again that parts fixation is firm, a hand-held screw tap, one holds the clamping tool, detains screw thread in aperture 2~3
Under guidance, the processing of each part complete thread is completed, after processing is completed, unclamps nut 2, passes through hole 5 and hole 7 with elongate rod, it will
Part ejects from below.
Embodiment one
By taking small magnetic conduction cap as an example, part maximum outside diameter 3.8mm, maximum gauge only 1.4mm, and Central of the parts have it is straight at one
Diameter is the fine thread of S0.6mm, length 0.8mm.Since the design of part is small, and screw thread is fine thread, and operator is in hand
When holding part and screw tap tapping, part can not be held steady and hold jail, cause screw tap and bottom outlet can not good centering, easily cause spiral shell
Line attacks deflection, screw tap fracture and other issues.It is using this clamping tool, then convenient for mounting and clamping, it is easy to operate, it can be achieved that adding in groups
Work, and can on small-sized tapping machine pre- tapping, significantly improve the quality and efficiency of micro parts Small Holes tapping.
