Abstract
The utility model discloses a circular rod clamping jig which comprises a machine seat, a tension sleeve in sliding connection with the machine seat, and a rocker arm hinged with the machine seat. The circular rod clamping jig is characterized in that a handle pushing the rocker arm to rotate is connected on the machine seat through threads, a hole containing a driven end of the rocker arm is formed in the redial direction of the tension sleeve, a restoration spring is connected between the tension sleeve and the machine seat, matched taper inclined faces are arranged on the outer wall of the tension sleeve and a working platform on the machine seat, and the inner wall of the tension sleeve is a movable clamping face used for fixing a workpiece. According to the circular rod clamping jig, a simple mechanical structure is used for clamping the workpiece with a cylindrical part, and therefore lathe machining is convenient; operation is simple; and clamping and loosening can be realized as long as the handle is screwed manually.
Description
Technical field
The utility model belongs to mechanical field, is specifically related to a kind of round bar 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 be processed, and for the ease of the processing of lathe to workpiece, need have the clamping device that clamps from workpiece inside to fix workpiece, because workpiece is various, need design different clamping devices to different workpieces.
The utility model content
The technical problems to be solved in the utility model provides a kind of round bar clamping device that the workpiece that has column part is clamped.
In order to solve the problems of the technologies described above, the utility model provides a kind of round bar clamping device, and the swelling cover and the rocking arm hinged with support that comprise support, are slidingly connected with support is characterized in that: being threaded on the support promotes the handle that rocking arm rotates; The footpath of swelling cover upwards is provided with the hole of ccontaining rocking arm driven end; Be connected with back-moving spring between swelling cover and the support; Outer wall and the workbench on the support of swelling cover are provided with the tapered slope that is complementary, and the inwall of swelling cover is the movable clamping area for fixation workpiece.
Described swelling cover is provided with the tubular body of the radius variable of axially open for tube wall.When carrying out clamping work pieces, turning handle impels rocking arm to rotate; the driven end of rocking arm rotates the whole swelling cover of pulling to lower slider; because the column part of workpiece is positioned at the cavity of swelling cover; and pinching end and the workbench on the support of swelling cover are provided with the tapered slope that is complementary; because the tapered slope on the support is fixing; make the pinching end of swelling cover in the center line gathering to the swelling cover in the process of lower slider of swelling cover; thus the column part of clamping work pieces plays the effect of clamping work pieces.When unclamping workpiece, oppositely turn handle, rocking arm rotates round about, swelling is enclosed within the effect of elastic-restoring force of back-moving spring and upwards slides, because the swelling cover is made by metal material, has certain restoring force, the pinching end of swelling cover outwards launches, and unclamps the clamping to the workpiece column part.
The utility model has been realized the workpiece that has column part is clamped by simple frame for movement, is convenient to machine tooling, and is simple to operate, only need turn handle and just can realize the work that clamps and unclamp.
As the further restriction of technical solutions of the utility model, for when the swelling cover unclamps, the restoring force of swelling cover does not exceed default scope, reduces the active force that applies when clamping simultaneously, and the stage casing of swelling cover is provided with stretch section.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
As shown in Figure 1, the utility model provides a kind of round bar clamping device, comprises support 3, is used for the swelling cover 4 of workpiece pressing 1, the rocking arm 6 hinged with support 3, the nut 7 that the drive end 61 that promotes rocking arm 6 of being threaded on the support 3 makes it to rotate; Swelling cover 4 is provided with the hole 10 of ccontaining rocking arm driven end 9; Be connected with stage clip 5 between the drive end of swelling cover 4 and the support 3; The pinching end 2 of swelling cover 4 is provided with the tapered slope that is complementary with the workbench on the support 3, and the pinching end 2 of swelling cover 4 also is provided with cavity.
When carrying out clamping work pieces 1, turning nut 7 impels rocking arm 6 to rotate; the driven end 9 of rocking arm 6 rotates the whole swelling cover 4 of pulling to lower slider; because the column part a of workpiece 1 is positioned at the cavity of swelling cover 4; and the pinching end 2 of swelling cover 4 is provided with the tapered slope that is complementary with workbench on the support 3; because the tapered slope on the support 3 is fixing; make the pinching end 2 of swelling cover 4 draw at swelling cover 4 center line to swelling cover 4 in the process of lower slider; thus the column part a of clamping work pieces 1 plays the effect of clamping work pieces 1.When unclamping workpiece 1, oppositely turn nut 7; rocking arm 6 rotates round about; swelling cover 4 upwards slides under the effect of the elastic-restoring force of stage clip 5; because swelling cover 4 is made by metal material; have certain restoring force, the pinching end 2 of swelling cover 4 outwards launches, and unclamps the clamping to workpiece column part a.
For when swelling cover 4 unclamps, the restoring force of swelling cover 4 does not exceed default scope, reduces the active force that applies when clamping simultaneously, and the stage casing of pinching end 2 is provided with stretch section 21 on the swelling cover 4.
For clamped workpiece 1 is positioned, support 3 is provided with alignment pin 11.
Above-described only is preferred embodiment of the present utility model, should be understood that for a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement, these can not influence effect and practical applicability that the utility model is implemented.
Claims (2)
1. round bar clamping device, the swelling cover that comprise support, is slidingly connected with support and the rocking arm hinged with support, it is characterized in that: being threaded on the support promotes the handle that rocking arm rotates; The footpath of swelling cover upwards is provided with the hole of ccontaining rocking arm driven end; Be connected with back-moving spring between swelling cover and the support; Outer wall and the workbench on the support of swelling cover are provided with the tapered slope that is complementary, and the inwall of swelling cover is the movable clamping area for fixation workpiece.
