Description
Technical field
The present invention relates to parts machining field, be specially a kind of clamping tooling for pipe.
Background technology
Along with the development of modern mechanical processing industry, to quality, the improving constantly of required precision of cutting, to production cost of enhancing productivity, reduce, there is the requirement of automatic cutting system of high-intelligentization also in lifting.
In existing processing and manufacturing, mostly adopt the scroll chuck be made up of chuck body, movable jaw and claw driving mechanism to clamp flexible, structure is comparatively complicated, and the maintenance also more complicated to scroll chuck.
Summary of the invention
The present invention is in order to solve in existing processing and manufacturing, and the problem of the complicated structure of the scroll chuck adopted when being fixed pipe, the object of the present invention is to provide a kind of structure simply for the clamping tooling of pipe.
The invention provides base case is: for the clamping tooling of pipe, comprise pedestal, control stick group and annular brake shoe group, wherein, described pedestal is provided with loose slot, the bottom of described loose slot is provided with movable span, described control stick group is hinged in described movable span, described control stick group comprises the first control stick and the second control stick, the bottom of described first control stick and the bottom of described second control stick are connected with flexible member, described annular brake shoe group comprises the first annular brake shoe and the second annular brake shoe, the top of described first control stick is connected with described first annular brake shoe, the top of described second control stick is connected with described second annular brake shoe.
The operation principle of base case: when needs are fixed pipe time, active force is applied to the bottom of control stick group, make the bottom of the first control stick and the bottom move toward one another of the second control stick, due to control stick group and loose slot hinged, the top of the first control stick and the top move toward one another of the second control stick, namely the distance between the first control stick and the second control stick reduces, now, pipe to be fixed is placed on pedestal, after making the top of control stick group stretch into the inside of pipe, after removing out the active force to the applying of control stick group, flexible member is no longer after forced compression, start to recover deformation thus the control stick group force connected two ends, make the first control stick and the second control stick from motion, distance between first control stick and the second control stick increases, drive the first annular brake shoe and the second annular brake shoe from motion, thus the inwall of pipe is clamped, and then pipe is fixed on pedestal.
The beneficial effect of base case is: compare in existing processing and manufacturing and adopt baroque scroll chuck to clamp pipe, annular brake shoe group is driven to be fixed pipe in pipe inside to manipulation group force when utilizing the deformation of flexible member self-recovery, easy and simple to handle, structure is simple.
Preferred version one: based on scheme preferred, described flexible member is spring; Beneficial effect: adopt spring as after flexible member, saved the production cost of frock.
Preferred version two: preferably one preferred, described annular brake shoe group surface is provided with frictional layer; Beneficial effect: after the surface of annular brake shoe group arranges frictional layer, increases the friction of annular brake shoe group and round tube inner wall, thus makes the fixed effect of pipe better.
Preferred version three: preferably two preferred, the bottom of described control stick group is provided with rubber layer; Beneficial effect: by arranging rubber layer to the bottom of control stick group, utilize the elasticity of rubber self, makes the effect when gripping the bottom of manipulation group more comfortable.
Excellent alternative four: preferably three preferred, the hinged place of described control stick group and described movable span is provided with bearing; Beneficial effect: by after hinged place arranges bearing, reducing the wearing and tearing of control stick group when rotating, extending the service life of control stick group.
Accompanying drawing explanation
Fig. 1 is the sectional view of the present invention for the clamping tooling embodiment of pipe.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: pedestal 100, loose slot 102, movable span 103, first control stick 201, second control stick 203, the annular brake shoe 209 of spring the 205, first annular brake shoe 207, second, pipe 300.
The clamping tooling for pipe as shown in Figure 1, comprise pedestal 100, control stick group and annular brake shoe group, pedestal 100 is provided with loose slot 102, the bottom of loose slot 102 is provided with movable span 103, control stick group is hinged in movable span 103, the hinged place of control stick group and movable span 103 is provided with bearing, control stick group comprises the first control stick 201 and the second control stick 203, the bottom of the first control stick 201 and the bottom of the second control stick 203 are connected with spring 205, the bottom of control stick group is provided with rubber layer, annular brake shoe group surface is provided with frictional layer, annular brake shoe group comprises the first annular brake shoe 207 and the second annular brake shoe 209, the top of the first control stick 201 is connected with the first annular brake shoe 207, the top of the second control stick 203 is connected with the second annular brake shoe 209.
When needs are fixed pipe 300 time, active force is applied to the bottom of control stick group, make the bottom of the first control stick 201 and the bottom move toward one another of the second control stick 203, due to control stick group and loose slot 102 hinged, the top of the first control stick 201 and the top move toward one another of the second control stick 203, namely the distance between the first control stick 201 and the second control stick 203 reduces, now, pipe 300 to be fixed is placed on pedestal 100, after making the top of control stick group stretch into the inside of pipe 300, after removing out the active force to the applying of control stick group, flexible member is no longer after forced compression, start to recover deformation thus the control stick group force connected two ends, make the first control stick 201 and the second control stick 203 from motion, distance between first control stick 201 and the second control stick 203 increases, drive the first annular brake shoe 207 and the second annular brake shoe 209 from motion, thus the inwall of pipe 300 is clamped, and then pipe 300 is fixed on pedestal 100, compare in existing processing and manufacturing and adopt baroque scroll chuck to clamp pipe 300, annular brake shoe group is driven to be fixed pipe 300 in pipe 300 inside to manipulation group force when utilizing the deformation of flexible member self-recovery, easy and simple to handle, structure is simple, adopt spring 205 as after flexible member, save the production cost of frock, after the surface of annular brake shoe group arranges frictional layer, increase the friction of annular brake shoe group and pipe 300 inwall, thus make the fixed effect of pipe 300 better, by arranging rubber layer to the bottom of control stick group, utilizing the elasticity of rubber self, making the effect when gripping the bottom of manipulation group more comfortable, by after hinged place arranges bearing, reducing the wearing and tearing of control stick group when rotating, extending the service life of control stick group.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite not departing from structure of the present invention; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
