Abstract
The utility model provides a quick clamping-interchanging type grinding fixture of a wedge-shaped workpiece, belongs to machining work fixtures, and relates to a machining fixture of a grinding machine. The fixture comprises a bottom plate, a locking pressing bar, sliding pressing bars, guide rails, guide rail anti-disengaging blocks, a clamping claw, a hinge pin and a locking handle. The bottom plate of the fixture is a sheet cuboid made of cast iron or low-carbon steel, and the size of the bottom plate is set according to needs and does not exceed the geometric size of an electromagnetic sucker; flatness of an upper large surface and flatness of a lower large surface of the bottom plate are guaranteed through ground finishing, and perpendicularity of a bottom surface and parallelism of two sides of the bottom plate are guaranteed through the two sides of the bottom plate; the locking pressing bar is fixed through bolts at the right end of the bottom plate, one side of the far left sliding pressing bar is clamped by the clamping claw, and the clamping claw impacts the far left sliding pressing bar because of rotation of an eccentric hand wheel; the bearing guide rails are installed on the two sides of the bottom plate and between the locking pressing bar and the clamping claw, so the fact that bearings at the two ends of the sliding pressing bars are installed in the bearing guide rails is guaranteed, and the guide rail anti-disengaging blocks are arranged at the two ends of the bearing guide rails. The quick clamping-interchanging type grinding fixture of the wedge-shaped workpiece has interchangeability, time for workpiece installation carried out by the fixture is greatly shortened, and production efficiency is improved.
Description
Technical field
The utility model belongs to machining tool clamp; The fixture that relates to a kind of grinding machine processing.
Background technology
The tradition grinding machine is all to adopt magnechuck to hold part directly to process, and to the requirement of part: at first material must be held by magnetic, such as steel, iron etc.; Next adopt magnechuck to hold part directly to add man-hour can not area too small, area too small can not across between the magnechuck magnetic coil apart from length, magnetic force just effect less than on part, thereby can not hold part, processing can't be carried out.
The material that can not be held for other is as copper, stainless steel, quartz etc., on grinding machine, process also must take special method to carry out clamping to fix.Existing solution adopts vacuum to inhale the way that fixture replaces mostly, and this kind of way cost is high, also needs to use pumping plant, has increased working space.
When need between the too small magnechuck magnetic coil of working (finishing) area apart from length and side and the little workpiece 7 of carving the type piece of bottom surface off plumb the time, adopt vacuum fixture because the too little area that does not become vacuum fixture absorption in bottom surface, have potential safety hazard in processing, so above way also can't resolve the clamping problem.
The utility model provides at the little clamping device of carving the type part of grinding machine processing, has met processing request, can guarantee safety again.
The utility model content
Carve type workpiece Quick-clamped interchangeable clamp, comprise base plate, stop press strip, slip press strip, bearing guide, guide rail anti-drop block, compress pawl, bearing pin, set lever; Described clamp bottom board is cast iron or the tabular cuboid of mild steel, and the base plate size is set as required but is no more than the physical dimension of magnechuck; Upper and lower large of base plate guarantees flatness through grinding, and the base plate both sides guarantee and the perpendicularity of bottom surface and the depth of parallelism between the two; Base plate right-hand member bolt fixed stop press strip, the clamped pawl in Far Left slip press strip right side is pushed down, and clamp jaw is subject to eccentric hand wheel rotating effect to compress the slip press strip; Between stop press strip, clamp jaw, bearing guide is installed in the base plate both sides, guarantees that slip press strip bearings at both ends is arranged in bearing guide, and the bearing guide two ends are provided with the guide rail anti-drop block.
During use, magnechuck is opened power generation magnetic, holds described clamp bottom board, in the effect lower clamp suction tightly of magnetic force on magnechuck.Described fixture has interchangeability, when grinding, can workpiece 7 be installed on another described fixture, and grinding can be changed another described fixture after completing like this, and its set-up time shortens short greatly, and production efficiency improves.

The specific embodiment
As shown in Figure 1,
The utility model comprises: base plate 10, stop press strip 12, slip press strip 8, bearing guide 6, guide rail anti-drop block 4, compression pawl 3, bearing pin 2, set lever 1 etc.
Carve the described base plate of type workpiece Quick-clamped interchangeable clamp 10 for cast iron or the tabular cuboid of mild steel, base plate 10 up and down large guarantee flatness through grinding, base plate 10 both sides guarantee and the perpendicularity of bottom surface and the depth of parallelism between the two; Base plate 10 right-hand member bolt fixed stop press strips 12, guarantee that it carves the profile bus vertical with base plate 10 both sides; The Far Left slip press strip 5 clamped pawls 3 in right side are pushed down, thereby clamp jaw 3 is subject to eccentric handwheel 1 rotary action to compress slip press strip 5, compresses and carve type workpiece 7 being attached on base plate plane tightly; Between stop press strip 8, clamp jaw 3, bearing guide 6 is installed in base plate 10 both sides, guarantee that bearing guide 6 trajectories are parallel to the large face of base plate 10, the bearings at both ends 9 that simultaneously guarantees slip press strip 8 is arranged on after bearing guide 6 can planar slide on base plate, and bearing guide 6 two ends are provided with guide rail anti-drop block 4.
As Fig. 2, shown in Fig. 3, carve type workpiece Quick-clamped interchangeable clamp described slip press strip 8 two sides and workpiece 7 side couplings, workpiece 7 is fixing between slip press strip 8, slip press strip 8 height are lower than workpiece 7 height, the workpiece discharge areas 13 of workpiece 7 between slip press strip 8 be discharge in turn one by one, after neat workpiece 7 discharge by the slip press strip on the left side compression of sliding to the right, leftmost slip press strip 5 is pushed down the rear clamp jaw 3 of workpiece 7 along the close base plate of bearing pin 2, rotate eccentric handle, clamp jaw 3 is by eccentric handwheel 1 rotary action workpiece pressing 7, workpiece 7 is pressed in Plane Installation on base plate 10.
While unclamping workpiece 7, to the rightabout of workpiece pressing 7, rotate eccentric handle, the clamp jaw 3 of described fixture can rotate 90 degree along the bearing pin 2 eccentric handle thickness that outwards slides, and strengthens the sliding distance of slip press strip, has increased the space that workpiece 7 is installed.
During use, if workpiece 7 can not be held by magnetic action, open the power generation magnetic of magnechuck, hold base plate 10 bottom surfaces of described fixture, clamp clamps workpiece 7 completes grinding smoothly; If workpiece 7 can be held by magnetic action, open the power generation magnetic of magnechuck, hold described fixture while workpiece 7 and be attracted on firmly plane on chassis, increased clamping force during grinding, process more safe and reliable.
Carve type workpiece Quick-clamped interchangeable clamp and there is interchangeability, when grinding, workpiece 7 can be installed on another fixture, grinding is processed clean by magnechuck and base plate lower plane after completing like this, change another described fixture, its installation workpiece time shortens short greatly, and production efficiency improves.
