Description
Technical field
The present invention relates to a kind of pull-up, especially a kind of rod member pull-up belongs to the machine tool technical field.
Background technology
In mechanical device, need carry out interference fit with the miscellaneous part of mechanical device by rod member usually and be connected, need dismantle when device and adjust or maintenance, or sustain damage when needing to change when rod member, often rod member need be extracted from mechanical device part.At present, generally adopt special-purpose pulling tool to extract rod member, but this special-purpose pulling tool need be equipped with corresponding electric utility, floor space is big, and complex structure can't use in the narrow and small place in field and space that lacks electric utility.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, take up room little, be fit to the rod member pulling tool that use in the narrow and small place in field and space.
The present invention is achieved by the following technical programs:
A kind of rod member pull-up comprises clamping device, drawing mechanism, and described clamping device comprises sleeve, retaining mechanism, and sleeve one end has the axial elastic trough that communicates with end face; Retaining mechanism is arranged on sleeve one end, comprise the clamp, clamping screw, the locking nut that are arranged on the sleeve both sides, sleeve one end is enclosed within on the rod member outer end, and clamp is sleeved on the sleeve, by clamping screw, locking nut rod member is fixedlyed connected with sleeve one end; Described drawing mechanism comprises that slide block, slide bar, slide bar outer end are provided with thrust block, and slide bar is inner fixedlys connected with the sleeve other end, and slide block set is contained on the slide bar, is connected slidably with slide block, and the slide block both sides are respectively equipped with handle.
Purpose of the present invention can also further realize by following technical measures.
Aforesaid rod member pull-up, wherein said retaining mechanism comprises mounting blocks, is symmetricly set on several holding screws of mounting blocks both sides, described mounting blocks is sleeved on sleeve one end, during locking, several holding screw one ends pass respectively on the outer peripheral face that mounting blocks is resisted against sleeve axial elastic trough both sides.
The present invention is simple in structure, only needs manual operation, need not to use electric utility, and it is little to take up room.When needs are extracted rod member, clamp the rod member outer end by clamp mechanism earlier, then drawing mechanism is fixedlyed connected with clamp mechanism, hold the handle of slide block both sides, slide block is reciprocatingly slided before and after slide bar fast, and the thrust block of bump slide bar outer end is until extracting rod member.The present invention is easy to operation, is fit to the narrow and small place in field and space of no electric utility.
Advantage of the present invention and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention one;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the structural representation of the embodiment of the invention two.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
Embodiment one
As shown in Figure 1 and Figure 2, present embodiment comprises clamping device 1, drawing mechanism 2, and clamping device 1 comprises sleeve 11, retaining mechanism 12, and sleeve 11 1 ends have the axial elastic trough 111 that communicates with end face.Retaining mechanism 12 is arranged on sleeve 11 1 ends, comprise the clamp 121, clamping screw 122, the locking nut 123 that are arranged on the sleeve both sides, sleeve 11 1 ends are enclosed within on rod member 3 outer ends, clamp 121 is sleeved on the sleeve 11, by two clamping screws 122, two locking nuts 123 rod member 3 is fixedlyed connected with sleeve 11 1 ends, be provided with the arc groove that can contain sleeve 11 outer peripheral faces in the clamp 121.Drawing mechanism 2 comprises that slide block 21, slide bar 22, slide bar 22 outer ends are provided with the thrust block 23 of diameter greater than slide bar 22, the inner connecting axle 112 with sleeve 11 other ends of slide bar 22 is fixedlyed connected by screw thread, slide block 21 is sleeved on the slide bar 22, can slide along slide bar 22 front and back.Slide block 21 both sides are respectively equipped with the handle 24 that is threaded with slide block 21.
When needs are extracted rod member 3, earlier sleeve 11 1 ends are packed into rod member 3 outer ends, tighten clamping screw 122, locking nut 123 again, make the arc groove of clamp 121 tightly clamp the axial elastic trough 111 of sleeve 11, make it that strain take place and clamp rod member 3.Connecting axle 112 with sleeve 11 1 ends is screwed in the slide bar 22 then, and slide bar 22, sleeve 11, retaining mechanism 12 are linked into an integrated entity with rod member 3.Hold the handle 24 of slide block 21 both sides,, slide block 21 is reciprocatingly slided fast along slide bar 22 front and back, the thrust block 23 of bump slide bar 22 outer ends makes rod member 3 constantly be subjected to greater impact power, until extracting.
Embodiment two
As shown in Figure 3, present embodiment and embodiment one structure, principle are identical, difference is that retaining mechanism 12 comprises mounting blocks 12-1, is symmetricly set on 4 holding screw 12-2 of mounting blocks 12-1 both sides, holding screw 12-2 screws on mounting blocks 12-1, and mounting blocks 12-1 is sleeved on sleeve 11 1 ends.Tighten holding screw 12-2, make the one end pass mounting blocks 12-1, tightly be resisted against on the sleeve groove 111 both sides outer peripheral faces, thereby mounting blocks 12-1, sleeve 11 are linked into an integrated entity with rod member 3, can extract the operation of rod member 4.
In addition to the implementation, the present invention can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of requirement of the present invention.
