Description
Technical field
The utility model relates to a kind of clamping device, and more particularly, it relates to a kind of convenient clamping device extracting gag.
Background technology
On lathe guide rail in lathe, by the time workbench is adjusted to after suitable position, usually can utilizes gag; workbench and guide rail are fixed; prevent equipment from occurring vibrations when running, tilting, the wearing and tearing of machine can be decreased, saved the replacing of fund and machine part.
At present, lathe on market all utilizes screw rod to be clamped by gag, but in practical operation, after gag is filled in, when machining, there will be certain vibrations, generally be inclined-plane state due to gag, after the time of one end, can there is stronger conflict with screw rod in gag, when back-outing, being very easy to the flat recess of screw rod end or cross recess to twist use up, there is very inconvenient situation in the processing so just for machinery.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of clamping device utilizing handle and ratchet to be unscrewed by screw rod comparatively easily.
For achieving the above object, the utility model provides following technical scheme: a kind of convenient clamping device extracting gag, comprise screw rod, described screw flight end is arranged on Lathe bench, described screw rod is provided with the baffle plate for gag of conflicting, described screw rod is fixed with ratchet away from the end of Lathe bench, described ratchet is arranged with described screw rod is concentric, described ratchet is provided with the runner assembly with described ratchet clamping, described runner assembly comprises shell, described casing is on described screw rod, described shell is provided with the fixture block with ratchet clamping on described ratchet, spring is provided with between described fixture block and described shell, described shell is fixed with handle, described shell and described handle are integrated setting.
The utility model is set to further: the ratchet on described ratchet is unidirectional ratchet.
The utility model is set to further: described ratchet is provided with flat recess or cross recess away from the side of screw rod.
The utility model is set to further: be provided with bearing between described shell and described screw rod, and described shell is fixedly connected with the outer ring of bearing, and described screw rod is fixedly connected with described bearing inner race.
Compared with prior art, the utility model has the advantage of, when installation gag, first gag is placed between the guide rail of lathe and workbench, utilize screwdriver, screw rod is screwed into screw rod, baffle plate and gag are conflicted, gag can be sticked between gap space, can ask and Lathe bench and guide rail can be fixed up; By the time machine work complete after, when needing travelling table position, turning handle, pawl wheel can be driven, the rotation of ratchet drives the rotation of screw rod, thus makes it possible to oppositely back-out, and constantly swings up and down handle, the arm of force utilizing handle longer makes originally very tight bolt be unscrewed from screw very easily, more slowly screws down and just can; Unidirectional ratchet on ratchet, only stirred toward the direction of turning on by ratchet for fixture block, utilize spring, fixture block can effectively reset, and handle in swing more by a small margin, can meet the feature of bolt installing/dismounting narrow space.
Accompanying drawing explanation

Fig. 4 is convenient the second local structural graph extracting the clamp embodiment of gag of the utility model.
Reference numeral: 1, screw rod; 2, baffle plate; 3, ratchet; 31, flat recess; 4, shell; 41, handle; 42, bearing; 43, fixture block; 44, spring; 5, workbench; 6, guide rail; 7, gag.
Detailed description of the invention
Referring to figs. 1 through Fig. 4, the convenient clamp embodiment extracting gag of the utility model is described further.
A kind of convenient clamping device extracting gag 7, comprise screw rod 1, the end of thread of described screw rod 1 is arranged on Lathe bench 5, described screw rod 1 is provided with the baffle plate 2 for gag 7 of conflicting, end away from Lathe bench 5 is fixed with ratchet 3 to described screw rod 1, described ratchet 3 is arranged with described screw rod 1 is concentric, described ratchet 3 is provided with the runner assembly with the clamping of described ratchet 3, described runner assembly comprises shell 4, described shell 4 is enclosed within described screw rod 1, described shell 4 is provided with the fixture block 43 with ratchet clamping on described ratchet 3, spring 44 is provided with between described fixture block 43 and described shell 4, described shell 4 is fixed with handle 41, described shell 4 is integrated setting with described handle 41.
The clamping device of described convenient extraction gag 7 is mounted in the clamping gag 7 on lathe, turn screw rod 1, gag 7 fixedly can be filled in inside the space between workbench 5 and guide rail 6, entirety is fixed up, reduce vibrations, also by loosening screw rod 1, gag 7 is taken off; Both, for what generally use in factory, for being with bevelled gag 7, can block by described gag 7 preferably.
Preferably, because shell 4 is thinner, so the same with the position that handle 41 is installed, as shown in Figure 4, spring 44 is positioned at handle 41 place with the fixture block 43 of a part to the present embodiment.
By adopting technique scheme, ratchet 3, spring 44 is utilized to coordinate with fixture block 43, make unidirectional being rotated by ratchet 3 of handle 41 energy, so just, can be smoothly very convenient when back-outing, usually in the process used, generally screw rod 1 can not be screwed down, if handle 41 plurality of pendulums dynamic several times gag 7 is unscrewed just passable; Spring 44 also plays and can, by fixture block 43 being squeezed on ratchet 3 tightly, ratchet 3 can be stuck, thus realizes handle 41 and drive shell 4 to rotate, and utilizes ratchet 3 to drive screw rod 1 to rotate.
Ratchet on described ratchet 3 is unidirectional ratchet.
By adopting technique scheme, unidirectional ratchet ensure that and can rotate backward handle 41, and fixture block 43 can coordinate spring 44 to complete reset.
Described ratchet 3 is provided with flat recess 31 or cross recess away from the side of screw rod 1, and what represent in the present embodiment accompanying drawing is flat recess 31.
By adopting technique scheme, flat recess 31 or cross recess are the lines of spiral more on market, screwdriver can be coordinated, drive screw 1 rotates, when twisting inside, it is not very large for having an effect due to needs, so only utilize screwdriver to drive flat recess 31 or cross recess just can be more quick and convenient by screw rod 1 screwin, need not bother very much.
Be provided with bearing 42 between described shell 4 and described screw rod 1, described shell 4 is fixedly connected with the outer ring of bearing 42, and described screw rod 1 is fixedly connected with described bearing 42 inner ring.
By adopting technique scheme, bearing 42 1 can ensure that shell 4 is enclosed within screw rod 1, also can ensure that shell 4 in the cofree movement of screw rod 1, can make shell 4 can not link with screw rod 1, maintain the normal operation of whole mechanism along with handle 41.
