Abstract
The invention relates to a clamp which is mainly used for matching with strengthening equipment (a cold rolling R machine of a fastener) for the corner surface of the fastener. The clamp comprises a three-jaw chuck 1, a height adjuster 2, an angle adjuster 3 and a roller 4, wherein the angle adjuster 3 is fixed on the height adjuster 2 and consists of an angle adjuster substrate 31, a roller support 32, an elastic pretightening piece, a hinge 35, a hinge shaft 36, an angle adjustment bolt 37, a crank mechanism 38 and a roller shaft 39. The clamp is suitable for parts of various specifications and is easy to operate, rolling force is easy to control, the double image of the parts is reduced, and the yield of the parts is improved.
Description
Technical field
The present invention relates to a kind of anchor clamps of machining, relate generally to the anchor clamps that securing member corner process equipment uses.
Background technology
The quality of securing member corner strengthening effect; Can conform to quality requirements; Except closely related with the size that is applied to the power on the securing member, roll extrusion time; The most important thing is whether jig Design reasonable, anchor clamps directly determined to be easy to workpiece adjust to after the roll extrusion position that needs, the roll extrusion whether surface quality (as should there not being ghost image), the roll extrusion angle of part correct, whether operator's clamping parts convenient etc.
Existing fixtures, three rollers points of contact with the workpiece surface is formed, whether in the horizontal plane, is to rely on roller bracket jig manufacturing process to ensure that, and can not be adjusted (stent is fixed, no height adjustment of the mechanical structure); roller axial center plane and the horizontal angle is fixed (stent as a whole, a good stent manufacturing, the structure is fixed, so the angle can not be changed nature), to a different angle, need to replace the different specifications of the stent, it is necessary specifications of the stent; clamp bracket is placed freely in the chuck jaws, the (radial direction along the chuck to move freely), the operator's part to take place, the bracket locations often change, resulting in an inconsistent state workpiece; fixture clamping force without pre operator usually requires both hands to take place the workpiece; most critical is that bracket can rotate freely up and down (because there is no hinge mechanism), so (workpiece squeezed pressure deformation should have) along the radial rollers automatically tighten (automatic feed) function (weak), mainly rely on the force stent deformation and gravity changes produced, allowing the automatic tightening along the wheel radial amplitude range small (because the original holder jig requires both a high strength to support the great rolling force, but also requires a certain amount of deformation holder to generate an automatic feed function, the manufacturing process is difficult to ensure), and difficult to control (due to primary clamp bracket deformation of the force determined by the manufacturing process, while the center of gravity often occurs due to the position change holder to randomly change).
Summary of the invention
The objective of the invention is to the weak point that exists in the above-mentioned prior art; But provide a kind of roller height separately free adjustment, roller shaft to the angle free adjustment of median plane and horizontal plane; Adopt a cover support; But just can adapt to needs, the processing work of various angles the diameter free adjustment, have preparatory clamping force; Be easy to pick and place workpiece, and can singlehanded pick and place the anchor clamps of workpiece.
In order to achieve the above object; The present invention includes scroll chuck, height arm control, angle adjuster and roller; Be fixed with height arm control on the claw of scroll chuck, be fixed with angle demodulator on the height adjuster, roller is installed on the roller shaft of angle demodulator front end.
Angle adjuster by angle adjuster substrate, rolling wheel support, stand spring, hinge, hinge axis, angle adjustment bolt, crank mechanism constitute, roller shaft forms; Rolling wheel support is connected with the angle adjuster substrate through hinge; Crank mechanism is installed on the rolling wheel support rear end; The angle adjustment bolt is installed on the crank mechanism; The lower end is by the angle adjuster base plate supports; The elasticity preload piece is housed on the hinge axis, and front end has the roller shaft that is connected with roller.
The elasticity preload piece can be torsion spring, spring or flexure strip.Stand spring makes rolling wheel support have the downward pretightning force of roller end; Through adjusting angle adjustment bolt; Can freely adjust the angle of roller shaft to median plane and horizontal plane; And can easily roller and rolling wheel support be lifted with hand; Be convenient to load and unload part; And because the existence of angle adjuster upper hinge; Roller shaft can freely change to the angle of median plane and horizontal plane; After the clamping radius of scroll chuck is set up; Roller can radially not move forward and backward along scroll chuck, has guaranteed that the clamping position of each part is constant.In the processing parts process; When part receives securing member outer corner surface strengthening device main shaft power vertically downward; After the contact-making surface of part and roller is extruded distortion; The part height slightly reduces; Because the clamping constant radius of scroll chuck is constant; Because of the existence of angle adjuster upper hinge, roller shaft diminishes to the angle of median plane and horizontal plane slightly, thereby the present invention who makes has auto-feed function flexibly.
Scroll chuck is a standard chuck structure, and during work, the chuck base plate is fixed on the workbench with pressing plate, regulates the part of scroll chuck applicable to clamping different-diameter size.
The present invention has following beneficial effect than prior art.
The present invention can replace prior art one sleeve clamp and need the plurality of specifications support.Because angle adjuster can freely be adjusted the angle of roller shaft to median plane and horizontal plane, to adapt to the needs of processing different size part.
The present invention adopts the angle adjuster with hinge arrangement as rolling wheel support; Realize the auto-feed of roller radial direction; Replacing prior art relies on the stress deformation of support and the change of support center of gravity to produce; Making increases much along the roller amplitude range of tightening up automatically radially, and is easy to be subjected to the control of roll extrusion power.
Structure of the present invention; The operator lifts roller and rolling wheel support with hand easily; Be convenient to one hand and pick and place part; (because the pretightning force that stand spring produces; When the operator puts down roller and rolling wheel support; They can automatically restore to the clamped state of part); And because the existence of angle adjuster upper hinge; Roller shaft can freely change to the angle of median plane and horizontal plane; After the clamping radius of scroll chuck is set up; Roller can radially not move forward and backward along scroll chuck, has guaranteed that the clamping position of each part is constant.
The present invention can regulate the height of each claw separately, is easy to make the contact point of three rollers and workpiece on short transverse, to be in same plane, has guaranteed that institute's processing parts can not scrap because of producing ghost image (being commonly called as double-edged eyelid).
Structure of the present invention, because of roller height height, roller shaft to the diameter of the angle of median plane and horizontal plane, clamping parts scalable all, so reduced requirement to the anchor clamps machining accuracy.
