Abstract
The invention discloses a powerful extraction tool. The tool comprises clamping jaws, a supporting head, an adjusting screw cap, a pulling rod and a pulling collision block, wherein the clamping jaws are connected to the supporting head through cylindrical pins; the adjusting screw cap is screwed on the supporting head; the supporting head is screwed on the pulling rod; and the pulling rod is sleeved with the pulling collision block. According to the tool, the opening angle between the two clamping jaws is adjusted through screwing of the adjusting screw cap, the clamping jaws extend into a sleeve and are clamped, then the pulling collision block hits against the pulling rod, and then the sleeve can be pulled out. The sleeve is not required to be pulled out and replaced after electric welding, the time and the labor can be saved, and the working efficiency can be improved.
Description
Technical field
the present invention relates to Installing machine tool maintenance tool, particularly a kind of powerful pull-off instrument.
Background technology
at present, the guide pin bushing on lathe, lining, drill holder etc. need to be changed or need to change with after wearing and tearing for a long time in the time that processing is defective.And guide pin bushing, lining class are under the long term of iron filings, cutting fluid etc., on lathe, are difficult to split out replacing.Conventionally the practice is that weldering screw is putting, then extracts by drawbench, complicated operation, and spended time is of a specified duration, and heat when weldering screw can make the temperature distortion of lathe endoporus, and the cover of extracting can not re-use, poor effect.
Summary of the invention
the object of the present invention is to provide a kind of can fast dismantling the instrument of cover, simple to operate, operating efficiency is high, overcome electric welding in the past and pull out the shortcoming of cover complicated operation, length consuming time.
technical solution of the present invention is such, a kind of powerful pull-off instrument, comprise claw, regulate blind nut, straight pin, supporting member, drawing bar and drawing collision block, it is characterized in that claw comprises that two are connected on supporting member by straight pin, regulate blind nut to connect by M36 × 2 screw thread and supporting member, supporting member and drawing bar adopt M12 thread connection, and drawing collision block is enclosed within on drawing bar.
claw can rotate around straight pin, and the opening angle between two claws is adjustable, thereby blocks the cover end face of different-diameter.
claw rear portion is inclined-plane, and regulating blind nut internal upper part is the conical surface, contacts with claw inclined-plane, regulates the opening angle between adjustable two claws of blind nut, and maintain this angle by left-handed dextrorotation, makes claw block the cover that will pull out always.
drawing collision block is enclosed within on drawing bar, can be on drawing bar free vibration, the impulsive force drawing of clashing into drawing bar by collision block goes out cover.
supporting member, drawing bar, drawing collision block cylindrical have annular knurl.
there is barb claw termination.
Barb and the latch spoon of termination have oblique angle.
Drawing collision block is equipped with capstan handle.
regulating the bottom of blind nut (3) endoporus is M36X2 screw thread, and regulating the top of blind nut (3) endoporus is taper.
Claw (1) sole piece is bottom dog, and the interior outside of bottom dog is inclined-plane, and there is screw at drawing bar (5) center, top, and supporting member (4) bottom bar is screw rod.
advantage of the present invention is simple in structure, easy to manufacture, easy to use, and operating efficiency is high.Can be used for splitting out the lining, guide pin bushing, drill holder of various different-diameters etc., be applicable to the lathe containing cover class.

in Fig. 1～Fig. 6, claw (1), straight pin (2), regulates blind nut (3), supporting member (4), drawing bar (5), drawing collision block (6).
The specific embodiment
below in conjunction with accompanying drawing, the invention will be further described.
Embodiment 1, with reference to accompanying drawing 1 to accompanying drawing 6, two claws (1) are connected with supporting member (4) by straight pin (2), claw (1) can rotate around straight pin (2), and the angle of opening between two claws (1) regulates blind nut (3) to regulate by left-handed dextrorotation.When use, first will regulate blind nut (3) to back-out, two claws (1) are close to, then two claws (1) are put in lining, put in the degree of depth and should be greater than liner sleeve length, then tighten and regulate blind nut (3), make two claws (1) open clamping bush end face, then left hand is held up drawing bar (5), and the right hand uses drawing collision block (6) to clash into back and forth, lining can be extracted.Easy and simple to handle, operating efficiency is high, and labour intensity is low, does not damage lathe.Comprise by claw, straight pin, adjusting blind nut, supporting member, drawing bar, drawing collision block and forming, structure is that two claws (1) are connected in support (4) by straight pin (2), regulate blind nut (3) to be connected with supporting member (4) by fine thread, screwing and unscrewing adjusting blind nut (3) is the opening angle between adjustable two claws (1), and supporting member (4) adopts and is threaded with drawing bar (5).It is upper that drawing collision block (6) is enclosed within drawing bar (5), adopts matched in clearance with drawing bar 5.
embodiment 2, a kind of powerful pull-off instrument, comprise claw, regulate blind nut, straight pin, supporting member, drawing bar and drawing collision block, it is characterized in that claw comprises that two are connected on supporting member by straight pin, regulate blind nut to connect by M36 × 2 screw thread and supporting member, supporting member and drawing bar adopt M12 thread connection, and drawing collision block is enclosed within on drawing bar.Claw can rotate around straight pin, and the opening angle between two claws is adjustable, thereby blocks the cover end face of different-diameter.Claw rear portion is inclined-plane, and regulating blind nut internal upper part is the conical surface, contacts with claw inclined-plane, regulates the opening angle between adjustable two claws of blind nut, and maintain this angle by left-handed dextrorotation, makes claw block the cover that will pull out always.Drawing collision block is enclosed within on drawing bar, can be on drawing bar free vibration, the impulsive force drawing of clashing into drawing bar by collision block goes out cover.Supporting member, drawing bar, drawing collision block cylindrical have annular knurl.There is barb claw (1) termination.Barb and the latch spoon of termination have oblique angle.Drawing collision block (6) is equipped with capstan handle.
