Abstract
The utility model relates to a kind of machining auxiliary implement.For ensureing the blind hole depth uniformity of processing on workpiece by the gross, the utility model provides a kind of keyhole degree of depth stop collar, comprise a cylindricality body, body internal diameter is consistent with the external diameter of drill bit for machining, it is characterized in that: an end face of described body is provided with the chip area caved inward, body endoporus runs through at the bottom of flute, at the bottom of flute rear portion cover body wall on be provided with screwed hole, be provided with trip bolt in screwed hole.This stop collar applicability is strong, effectively can raise labour efficiency, shorten the process-cycle, ensure process the uniformity of blind hole depth.
Description
Technical field
The utility model relates to a kind of machining auxiliary implement, specifically refers to a kind of keyhole degree of depth stop collar.
Background technology
Often need the blind hole getting out certain depth on workpiece when carrying out machining at present, the degree of depth of blind hole processing or estimate control by processor, or lean on the scale on drilling machine to control.Estimate control by processor and obviously can not meet by the gross that workpiece is to the conforming requirement of blind hole depth, simultaneously in process, blind hole is often drilled to through hole by the carelessness due to processor causes whole workpiece to be scrapped.Although and adopt the scale on drilling machine to carry out controlling to make the error amount of blind hole depth diminish, for the degree of depth have strict demand blind hole processing for, its error amount can not meet processing request.
Summary of the invention
For ensureing the blind hole depth uniformity of processing on workpiece by the gross, the utility model provides a kind of keyhole degree of depth stop collar.
For realizing above-mentioned technical purpose, the technical scheme that the utility model adopted is: keyhole degree of depth stop collar, comprise a cylindricality body, body internal diameter is consistent with the external diameter of drill bit for machining, it is characterized in that: an end face of described body is provided with the chip area caved inward, body endoporus runs through at the bottom of flute, at the bottom of flute rear portion cover body wall on be provided with screwed hole, be provided with trip bolt in screwed hole.
Described chip area, its degree of depth is greater than the width of thread on drill bit.
Described chip area, its width of rebate is greater than slot bottom width.
Described chip area, its slot bottom width is greater than the width of thread on drill bit.
The beneficial effects of the utility model: structure is simple, low cost of manufacture, easy to operate, repair and replacement are simple, flexibly, this stop collar applicability is strong, effectively can raise labour efficiency, shorten the process-cycle, ensure process the uniformity of blind hole depth.
Accompanying drawing explanation
Accompanying drawing 1 is perspective view of the present utility model.
Accompanying drawing 2 is side view of the present utility model.
Accompanying drawing 3 is the structural representation after the utility model is combined with drill bit.
Accompanying drawing illustrates: 1, body, 2, chip area, and at the bottom of 2-1, flute, 3, body endoporus, 4, trip bolt, 5, drill bit.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in accompanying drawing 1, accompanying drawing 2, keyhole degree of depth stop collar, comprise a cylindricality body 1, an end face of body 1 is provided with the chip area 2 caved inward, body endoporus 3 runs through 2-1 at the bottom of flute, at the bottom of flute rear portion cover body wall on be provided with screwed hole (invisible in accompanying drawing), be provided with trip bolt 4 in screwed hole.
As shown in Figure 3, during use, body 1 is enclosed within drill bit 5, according to the depth requirements of institute's drilling blind hole, adjust body 1 front end and drill bit 5 front end relative position, then trip bolt 4 is tightened and make body 1 and drill bit 5 strong bonded, after body 1 front end contacts with surface of the work, during drilling, limit going deep into further thus the working depth of blind hole being controlled of drill bit 5.
Known shown in 3 with reference to the accompanying drawings, body 1 is when making, and its diameter of bore requires consistent with the external diameter of drill bit for machining.
Because drill bit 5 is when holing, the material bits that workpiece gets out are discharged along the screw thread on drill bit, this material bits width is general consistent with the width of screw thread, when processing chip area 2 thus on body 1, require that the width of thread that the width of the degree of depth of chip area and bottom land 2-1 is greater than on drill bit is discharged smoothly to make material consider to be worth doing.
Be the smooth degree increasing excretion further, as shown in accompanying drawing 1 and accompanying drawing 2, the width of rebate of chip area 2 is greater than the width of bottom land 2-1 simultaneously, and whole chip area 2 is outwards opened in " eight " type.
By the application of this stop collar in actual production, the uniformity of the blind hole depth processed significantly improves, and depth error, generally between 0.02-0.03mm, has obvious reduction relative to traditional manufacturing tolerance value, effectively improves the crudy of blind hole.
