Abstract
The invention discloses a round rod clamping fixture, comprising a machine seat, an expansion sleeve and a rocker arm, wherein the expansion sleeve is connected with the machine seat in a sliding way; and the rocker arm is connected with the machine seat in a hinging way. The round rod clamping fixture is characterized in that a handle for pushing the rocker arm to rotate is connected onto the machine seat in a thread way; a hole for the accommodation of a driven end of the rocker arm is arranged in the radial direction of the expansion sleeve; a reset spring is connected between the expansion sleeve and the machine seat; tapered inclined planes matched with each other are arranged on the outer wall of the expansion sleeve and a working platform on the machine seat respectively; and the inner wall of the expansion sleeve is an active clamping face for the fixation of a workpiece. Through a simple mechanical structure, the round rod clamping fixture realizes clamping on the workpiece with a columnar part; in addition, the processing of a machine tool is facilitated; the operation is simple; and as long as the handle is screwed, the operations of clamping and loosening can be realized.
Description
Technical field
The invention belongs to mechanical field, be 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 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 a kind of round bar clamping device that workpiece with column part is clamped.
In order to solve the problems of the technologies described above, the invention provides a kind of round bar clamping device, the expansion sleeve that comprise support, is slidingly connected with support and the rocking arm hinged with support is characterized in that: being threaded on the support promotes the handle that rocking arm rotates; The footpath of expansion sleeve upwards is provided with the hole of accommodating rocking arm driven end; Be connected with back-moving spring between expansion sleeve and the support; Outer wall and the workbench on the support of expansion sleeve are provided with the tapered slope that is complementary, and the inwall of expansion sleeve is the movable clamping face for fixation workpiece.
Described expansion sleeve is the tubular body that tube wall is provided with the radius variable of axially open.When carrying out clamping work pieces, turning handle impels rocking arm to rotate; the driven end of rocking arm rotates the whole expansion sleeve down sliding of pulling; because the column part of workpiece is positioned at the cavity of expansion sleeve; and the pinching end of expansion sleeve is provided with the tapered slope that is complementary with the workbench on the support; because the tapered slope on the support is fixing; so that the pinching end of expansion sleeve in the process of expansion sleeve down sliding to the center line gathering of expansion sleeve; thereby 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, expansion sleeve is upward sliding under the effect of the elastic-restoring force of back-moving spring, because expansion sleeve is made by metal material, has certain restoring force, the pinching end of expansion sleeve outwards launches, and unclamps the clamping to the workpiece column part.
The present invention has realized the workpiece with 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 solution of the present invention, for when expansion sleeve unclamps, the restoring force of expansion sleeve does not exceed default scope, reduces simultaneously the active force that applies when clamping, and the stage casing of expansion sleeve is provided with stretch section.
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 round bar clamping device, comprise support 3, be used for the expansion sleeve 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; Expansion sleeve 4 is provided with the hole 10 of accommodating rocking arm driven end 9; Be connected with stage clip 5 between the drive end of expansion sleeve 4 and the support 3; The pinching end 2 of expansion sleeve 4 is provided with the tapered slope that is complementary with the workbench on the support 3, and the pinching end 2 of expansion sleeve 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 whole expansion sleeve 4 down slidings of pulling; because the column part a of workpiece 1 is positioned at the cavity of expansion sleeve 4; and the pinching end 2 of expansion sleeve 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; so that the pinching end 2 of expansion sleeve 4 center line to expansion sleeve 4 in the process of expansion sleeve 4 down slidings draws in; 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; expansion sleeve 4 is upward sliding under the effect of the elastic-restoring force of stage clip 5; because expansion sleeve 4 is made by metal material; have certain restoring force, the pinching end 2 of expansion sleeve 4 outwards launches, and unclamps the clamping to workpiece column part a.
For when expansion sleeve 4 unclamps, the restoring force of expansion sleeve 4 does not exceed default scope, reduces simultaneously the active force that applies when clamping, and the stage casing of pinching end 2 is provided with stretch section 21 on the expansion sleeve 4.
For clamped workpiece 1 is positioned, support 3 is provided with alignment pin 11.
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.
