Abstract
The invention discloses a clamping fixture for a tube body. The clamping fixture comprises an engine base, a handle, a pull rod and a clamping jaw, wherein the pull rod is vertically connected with the engine base in a sliding mode; the clamping jaw has a horizontal movement free degree; the handle is connected with the pull rod by a thread; two sides of the upper end of the pull rod are connected with the clamping jaw by an inclined surface which needs to be in slide contact; and a pin shaft radially arranged on the pull rod is connected with a strip hole on the clamping jaw in a sliding mode. The clamping device has a simple structure, is convenient to operate, and can clamp and loosen a workpiece by only needing to twist the handle.
Description
Technical field
The invention belongs to mechanical field, be specifically related to a kind of body clamping device.
Background technology
Clamping device is that the workpiece of having good positioning is fixed on the setting element in whole process reliably, and the mechanism that changes of occurrence positions not.When clamping work pieces, do not allow to destroy the location of workpiece, and enough rigidity should be arranged, guarantee necessary clamping force, but should not damage the workpiece machined surface or make workpiece produce distortion, thereby guarantee machining accuracy.Because the outer surface of most of workpiece need to be processed, and for the ease of the processing of lathe to workpiece, need to have the clamping device that clamps from inside workpiece to fix workpiece, because workpiece is various, need to design different clamping devices to different workpieces.
Summary of the invention
The technical problem to be solved in the present invention provides the body clamping device that a kind of vertical direction simple in structure compresses.
In order to solve the problems of the technologies described above, the invention provides a kind of body clamping device, comprise support, handle, the pull bar that be slidingly connected vertical with support and the jaw with the free degree of moving horizontally, handle is connected with pull rod screw, both sides, pull bar upper end are connected with the inclined-plane of jaw by sliding-contact, and the bearing pin that radially is provided with on the pull bar and the cylindrical void on the jaw are slidingly connected.
During clamping work pieces, workpiece is inserted in the cavity that makes the jaw balance be positioned at workpiece downwards along jaw, because the relative position between handle and the jaw does not change, and be threaded between handle and the pull bar, turning handle moves down pull bar, since the inclined-plane of pull bar can be big up and small down pyramidal structure, thereby extruding jaw in inclined-plane outwards launched the cavity of workpiece pressing when pull bar moved down, and realized the clamping to workpiece; Because what jaw adopted is metal material, has certain elastic-restoring force after the distortion, when oppositely turning handle, pull bar moves up, and jaw draws under the effect of elastic-restoring force, and removal is to the clamping action power of workpiece cavity.The clamping device of such scheme is simple in structure, easy to operate, only need turn handle and just can realize the clamping of workpiece and unclamp.The bearing pin that radially is provided with on the pull bar and the cylindrical void on the jaw are slidingly connected and can prevent the pull bar rotation.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of the embodiment of the invention.
The specific embodiment
As shown in Figure 1, the invention provides a kind of body clamping device, the pull bar 4 that comprises support 5, is fixed on the jaw 3 on the support 5 and is slidingly connected with jaw 3, the swelling end 1 tapered structure of described pull bar 4, the drive end handle 6 that has been threaded; Be provided with between jaw 3 and the pull bar 4 and prevent in relative rotation bearing pin 2.The both sides of jaw epimere are respectively inclined-plane and seal face, and the jaw stage casing is the stretch section that deforms, and the jaw hypomere is connected with support.
During clamping work pieces 7, workpiece 7 is inserted in the cavity that makes jaw 3 balances be positioned at workpiece 1 downwards along jaw 3, because the relative position between handle 6 and the jaw 3 does not change, and be threaded between handle 6 and the pull bar 4, turning handle 6 moves down pull bar 4, because the pyramidal structure that the swelling end 1 of pull bar 4 is big up and small down, thereby pull bar 4 moves down the cavitys that swelling end 1 extruding jaw 3 outwards launches workpiece pressings 1, realizes the clamping to workpiece 1; Because what jaw 3 adopted is metal material, has certain restoring force, when oppositely turning handle 6, move up at the effect lower link 4 of restoring force, jaw 3 draws in, and removal is to the clamping action power of workpiece 1 cavity.The clamping device of such scheme is simple in structure, easy to operate, only need turn handle 6 and just can realize the clamping of workpiece 1 and unclamp.
Above-described only is preferred embodiment of the present invention, should be understood that for a person skilled in the art, under the prerequisite that does not break away from structure of the present invention, can also make some distortion and improvement, these can not affect effect of the invention process and practical applicability.
