Abstract
The utility model relates to a clamp for internal grinding wing bearing seat, mainly adopting the following structure: a clamp body is provided with a supporting rack and a clamping screw; the locating block is arranged on the clamp body positioned inside the supporting rack, and one side of the clamp body is provided with a locating key; moreover, the locating block is arranged on the regulating groove body of the clamp body and both the locating block and the regulating groove body are fixed through set screw. Therefore, the utility model is characterized in a reasonable structure, convenient operation, stable clamping, being suitable for products of different specifications, no displacement during abrasive machining and high machining precision ,etc.
Description
The utility model relates to a kind of clamping tool for machine work, especially relates to a kind of aerofoil profile bearing block grinding out special fixture.
Bearing is a kind of traditional universal machine product, thereby its processing equipment still quite is subjected to people's attention to mechanical clamp.For example, someone has applied for the utility model patent of " super smart inside and outside circle anchor clamps " (patent No. 89207873.1) by name, it is a kind of anchor clamps that are applicable to bearing mill inside and outside circle, it mainly solves the axiality problem of producing high-precision bearing, to reach the requirement of producing C level or B level bearing, it comprises clamp body, retainer, needle roller, packing ring, parts such as nut are formed, according to the stationary fit principle, by the transmission of inside and outside circle clamp body and needle roller, the magnitude of interference in the stationary fit is directed into the workpiece that is rotated, reach direct clamping work pieces, improve axiality, the purpose that the product precision is improved.But this anchor clamps are only applicable to columniform bearing, are difficult to be applied to the machined of non-cylindrical bearing.
The aerofoil profile universal joint is adopted as a kind of novel product of universal joint increasingly extensively.But its bearing block has brought many inconvenience for the processing of product because of it is different.Wherein, grind at the interior circle to this bearing block and to add man-hour, owing to adopt existing plain clamp, exist production efficiency and owe high, clamp structure is comparatively complicated, heavy, and installs very conveniently, firmly, will influence the deficiencies such as quality of product often.
Goal of the invention of the present utility model is the deficiency that overcomes above-mentioned technology, provides a kind of rational in infrastructure, easy to operate, and clamping is stable, the aerofoil profile bearing block grinding out anchor clamps that accuracy is high.
Goal of the invention of the present utility model mainly is achieved by following technical proposals: be provided with bearing support and pinching screw on described clamp body; Described locating piece is arranged on the interior clamp body of bearing support, and is provided with positioning key on a side of clamp body.Usually, described bearing support can be frame type structure, can make with clamp body integral body, also can adopt welding or bolt to be connected and fixed and be integral.Described positioning key is parallel to the side plane of bearing support and is advisable.
Goal of the invention of the present utility model can also further be able to perfect by following technical proposals: described locating piece is arranged on the adjustment cell body of clamp body, and by hold-down screw with both stationary positioned.Like this, when need are changed product, only need by changing fixed block or adjusting its position, then applicable to the different product of processing.
In addition, in order further to be beneficial to of the present utility model installing and fixing, described clamp body is provided with the fixing hole perpendicular to the bearing support side plane, and is positioned at the outside of locating piece.Rear side upper surface centre between two locating pieces of described clamp body is provided with fixing backer, and the convex surface of workpiece to be processed is fixed against on the backer, and is more firm.
Therefore, the utlity model has rational in infrastructurely, easy to operate, clamping is stable, and is unshift in the Grinding Process applicable to the product of different size, characteristics such as machining accuracy height.
Accompanying drawing 1 is a kind of main TV structure schematic diagram of the present utility model;
Accompanying drawing 2 is A-A cutaway views of accompanying drawing 2;
Accompanying drawing 3 is a kind of structural representations of looking up of the present utility model.
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: clamp body 5 is provided with cell body, its both ends are provided with the bearing support 3 of frame type, both are fixed into one by hold-down screw 9, and in described cell body, be provided with two fixed blocks 4, be fixed on the clamp body 5 by hold-down screw 9 respectively, the spacing between two fixed blocks 4 and the width of processing work key body are matched; Front center at clamp body 5 cell bodies has a breach 12, so that production operation; Be provided with two fixing holes 6 in the nearly bottom of clamp body 5, thus this clamp body 5 be fixed on the machine tool chief axis ring flange; Be provided with two positioning keys 10 in a side of described clamp body 5, guarantee when anchor clamps are adjusted that all the time the centre of the concrete rear side of increment upper surface is provided with a backer 8 by hold-down screw on same benchmark, the convex surface of workpiece 11 is relied on this backer, play the role of positioning.
During production operation, the positioning key 10 that only needs to be fixed with the clamp body 5 of bearing support 3 is placed in two T-slots on the machine tool chief axis ring flange, and by bolt with its overall fixed on main shaft.Then, workpiece 11 is placed on the locating piece 4, the key body of its bottom center inserts between two locating pieces 4, and it is fixed that the clamped screw 2 in the top of workpiece 11 screws clamping.Then, like this, the grinding head of grinding machine can insert in the interior circular hole of workpiece 11 accurately and stably, when being machined to predetermined design size, unscrew pinching screw 2, take off workpiece 11, and then load onto new workpiece to be processed, and can repeat the processing of grinding out, rather convenient.
