Description
Technical field
The utility model relates to a kind of anchor clamps, particularly a kind of anchor clamps of processing connecting rod.
Background technology
Connecting rod is that two ends are hinged to transmit the rod member of motion and power with active and driven member respectively in the linkage.Connecting rod mostly is steel part, and it is circular or I-shaped that the cross section of its main part mostly is, and two ends are porose, and bronze bushing or needle bearing are housed in the hole, constitute hinged for packing pivot pin into.
Connecting rod is the strength member in the automobile engine, and it is connecting piston and bent axle, and its effect is that the reciprocating motion with piston changes rotatablely moving of bent axle into, and the power that acts on the piston is passed to bent axle with power output.Connecting rod except that the pressure that bears combustion chamber combustion gas generation, also will bear the inertia force of vertical and horizontal at work.
Therefore, connecting rod is worked under the stress state of a complexity.It not only had been subjected to tension and compression stress, but also the stress by bending of alternation.The main damage type of connecting rod is fatigue fracture and excessive deformation.Usually the position of fatigue fracture is three high stress areas on connecting rod.The condition of work of connecting rod requires connecting rod to have higher intensity and anti-fatigue performance; Require to have enough rigidity and toughness again.
When the processing connecting rod, generally adopt fixed flat planar anchor clamps processing connecting rod, so two ring plains of connecting rod become processing datum.So the flatness on two planes of two bars and the flatness of anchor clamps flat board have a significant impact the machining accuracy of part.But because two pitchs of holes of connecting rod are bigger, this causes the contact-making surface scope of its location datum level and base plate plane bigger, so this requires high to the flatness of bottom surface, connecting rod two hole and the flatness of anchor clamps base plate.
Summary of the invention
At the problems referred to above, the utility model provides a kind of anchor clamps of processing connecting rod, can make connecting rod be easy to the location, improves the part shape precision.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of anchor clamps of processing connecting rod, comprise clamp body and clamping device, it is characterized in that: clamp body comprises the clamp base that is connected with workbench, be located at the side plate on the clamp base, be located at the cover plate on the side plate, clamping device comprises the backing plate that is arranged on the clamp base, first slide rail that is connected with backing plate and second slide rail, be mounted slidably the first adjustment plate on first slide rail, be mounted slidably the second adjustment plate on second slide rail, first slide rail and second slide rail extend along the direction that is parallel to each other.
Further, cover plate is provided with the hold down gag that is used for spacing connecting rod.
Further, the second adjustment plate is provided with the alignment pin that is used for positioning linkage rod.
Further, first adjust plate and the second difference in height of adjusting plate be 0.03-0.06mm.
The utility model adopts above structure, has the following advantages:
1, is convenient to the location of connecting rod, can improves the part shape precision;
2, can process a plurality of connecting rods simultaneously, improve working (machining) efficiency.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
In the above accompanying drawing: 1, clamp base; 2, backing plate; 3, first slide rail; 4, side plate; 5, first adjust plate; 6, cover plate; 7, hold down gag; 8, alignment pin; 9, second adjust plate; 10, second slide rail.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby protection domain of the present utility model is made more explicit defining so that advantage of the present utility model and feature can be easier to be those skilled in the art will recognize that.
The employing honing machine is processed the disk and the face of cylinder of connecting rod in the present embodiment.Honing machine is the grinding machine that utilizes honing head honing workpiece polished surface, so that it can meet the requirements of flatness, mainly is used in the hole of honing workpiece in the manufacturing industry such as automobile, tractor, hydraulic part, bearing, aviation with emery wheel spin finishing workpiece.
A kind of anchor clamps of processing connecting rod comprise clamp body and clamping device.
Clamp body comprises the clamp base 1 that is connected with workbench, is connected the side plate 4 that is located on the clamp base 1, is located at cover plate 6 on the side plate 4 by bolt by bolt.
Clamping device comprises the backing plate 2 that is arranged on the clamp base 1, first slide rail 3 that is connected with backing plate 2 and second slide rail 10; first slide rail 3 and second slide rail 10 extend along the direction that is parallel to each other; size according to connecting rod; selection has first of differing heights difference to adjust the plate 5 and the second adjustment plate 9; first adjusts plate 5 is adjusted plate 9 than second high 0.03-0.06mm; first adjusts plate 5 can slide on first slide rail 3; second adjusts plate 9 can slide on second slide rail 10, and the track that the track that the first adjustment plate slides and the second adjustment plate slide is parallel to each other.
During parts fixation, the processed nose end of connecting rod is placed on first and adjusts on the plane of plate 5, another nose end of not processing of connecting rod is placed on second and adjusts on the plane of plate 9, when honing lever stretches in the hole, oilstone expands and when contact with connecting rod, the plane of the bottom surface in another hole that does not process of connecting rod and the second adjustment plate 9 breaks away from fully, thereby has removed unnecessary location datum level, increase the positioning accuracy of part, improved the machining accuracy of part greatly.
In order to enhance productivity, a plurality of connecting rods are processed simultaneously, the utility model also is provided with hold down gag on cover plate 6, on the second adjustment plate alignment pin 8 is set, alignment pin 8 positions a plurality of connecting rods, limits its rotation, hold down gag 6 compresses connecting rod, prevent the irregular gap of bad student between a plurality of link members, hold down gag 6 also need and connecting rod between gapped, guarantee that connecting rod can do moving horizontally among a small circle man-hour adding.
By the utilization of such novel clamp, the machining accuracy of its valve rod improves greatly, and its circularity can reach 2 μ m, and cylindricity can reach 5 μ m.
The foregoing description only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model spirit essence change or modify, and all should be encompassed within protection scope of the present invention.
