Background technology
Workpiece grabbing mechanism is widely used in the field of machining, when transmitting roughly workpiece, can use conveyer belt and transmitting; When needs transmit comparatively accurately to workpiece, workpiece grabbing mechanism will be used.
Existing workpiece grabbing mechanism is two jaws be hinged, the bare terminal end of jaw is used for holding workpiece, the control end of jaw is used for exerting a force, although it is relatively simple for structure to adopt said structure to carry out holding workpiece, but there is following problem when clamping the workpiece of circular arc: because the curvature of the workpiece of circular arc is different, adopt same jaw to clamp the workpiece of different curvature, jaw can not be fitted preferably with workpiece, makes clamping effect not good.
Summary of the invention
The invention provides a kind of clamping device for clamping arc-shaped work, to solve the problem that a jaw can not be fitted preferably with the arc-shaped work of different curvature.
In order to solve the problems of the technologies described above, the invention provides following technical scheme: a kind of clamping device for clamping arc-shaped work, comprise base and two jaws for holding workpiece, two jaws are towards workpiece, also comprise control lever and two drive rods, control lever is slidably connected on base, two drive rod one end are connected with the inner side of two jaws respectively, the other end is all connected with control lever, described two jaws are divided into the first jaw and the second jaw, first jaw is provided with limited block, flexure strip and slide bar, first jaw has through hole, one end of slide bar is through through hole, the other end is connected with flexure strip, the quantity of limited block is two, two limited blocks are all positioned at the inner side of the first jaw, the length of flexure strip is greater than the distance between two limited blocks, flexure strip is slidably connected on two limited blocks, second jaw is provided with chuck, chuck is between two limited blocks.
Principle of the present invention is: push lever, the angle between drive rod and jaw is made to be tending towards 90 degree, the bare terminal end of two jaws can open, arc-shaped work correspondence is put into the flexure strip place between two jaws, pull control lever, two jaws can close up gradually, the one side of workpiece can offset with flexure strip, another side and the chuck of workpiece offset, flexure strip can be located 2 of contacting with two limited blocks to form the different segmental arc of curvature, two limited blocks determine the width of flexure strip in specific location, slide bar is used for sliding up and down with adjustable elastic sheet, to adapt to the arc-shaped work of different curvature.Chuck on second jaw, between two limited blocks, is convenient to by workpiece pre-tightening in the space that surrounds at two limited blocks, and because slide bar is also between two limited blocks, therefore chuck is convenient to drive flexure strip to slide up and down with adjustable elastic sheet.
Compared with prior art, the invention has the advantages that: when workpiece be in hold out against state time, flexure strip on first jaw can regulate according to the shape of arc-shaped work, chuck on second jaw is convenient to the upper-lower position regulating slide bar, flexure strip and chuck are fitted with workpiece preferably, the first jaw and the second jaw can be made to clamp the arc-shaped work of different curvature preferably.
Further, also comprise stage clip, one end of stage clip is connected on the first jaw, and the other end is connected with slide bar, makes flexure strip under the effect of stage clip elastic force, pushes against with workpiece.
Further, limited block has chute, flexure strip is slidably connected in chute, and flexure strip can slide in chute, ensure that the directed movement of flexure strip.
Further, the quantity of described chuck is at least two, and the power at chuck place balances mutually, prevents workpiece to produce eccentric moment.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:
Fig. 1 is that the present invention is for clamping the structural representation of the clamping device embodiment of arc-shaped work.
Detailed description of the invention
Reference numeral in Figure of description comprises: base 1, control lever 2, drive rod 3, first jaw 4, second jaw 5, limited block 6, flexure strip 7, chuck 8, stage clip 9, slide bar 10.
As shown in Figure 1, a kind of clamping device for clamping arc-shaped work in the present embodiment, comprise base 1, control lever 2, stage clip 9, two drive rod 3 and two jaws for holding workpiece, two jaws are towards workpiece.Control lever 2 is slidably connected on base 1, and two drive rod 3 one end are connected with the inner side of two jaws respectively, and the other end is all connected with control lever 2.Described two jaws are divided into the first jaw 4 and the second jaw 5.First jaw 4 is provided with limited block 6, flexure strip 7 and slide bar 10, first jaw 4 has through hole, one end of slide bar 10 is through through hole, the other end is connected with flexure strip 7, the quantity of limited block 6 is two, and two limited blocks 6 are all positioned at the inner side of the first jaw 4, and the length of flexure strip 7 is greater than the distance between two limited blocks 6, limited block 6 has chute, and flexure strip 7 is slidably connected in chute.One end of stage clip 9 is connected on the first jaw 4, and the other end is connected with slide bar 10.Second jaw 5 is provided with two chucks 8, and chuck 8 is between two limited blocks 6.
When carrying out piece-holder, first push lever 2, makes it control drive rod 3 and first jaw 4 and the second jaw 5 is opened, and at this moment, near workpiece, workpiece is between corresponding first jaw 4 and the second jaw 5.Pull control lever 2 again, two jaws can close up gradually, lower surface and the chuck 8 of workpiece offset, make it near flexure strip 7, finally can push against with flexure strip 7, flexure strip 7 can be located to form the different segmental arc of curvature at 2 that contact with two limited blocks 6, and two limited blocks 6 determine the width of flexure strip 7 in specific location, slide bar 10 is used for sliding up and down with adjustable elastic sheet 7, to adapt to the arc-shaped work of different curvature.
One end of stage clip 9 is connected on the first jaw 4, and the other end is connected with slide bar 10, makes flexure strip 7 under the effect of stage clip 9 elastic force, pushes against with workpiece.Flexure strip 7 is slidably connected in chute, and flexure strip 7 can slide in chute, ensure that the directed movement of flexure strip 7.The quantity of chuck 8 is at least two, and the power at chuck 8 place balances mutually, prevents workpiece to produce eccentric moment.Chuck 8 on second jaw 5, between two limited blocks 6, is convenient to by workpiece pre-tightening in the space that surrounds at two limited blocks 6, and because slide bar 10 is also between two limited blocks 6, therefore chuck 8 is convenient to drive flexure strip 7 to slide up and down with adjustable elastic sheet 7.
For a person skilled in the art, under the prerequisite not departing from structure of the present invention, can also make some distortion and improvement, 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.
