Abstract
The utility model relates to an eccentric clamp for the rotating quenching of small crank shafts, which comprises a platform and a shaft handle. The utility model is characterized in that the platform is provided with a transverse groove, and the transverse groove is provided with a pair of clamps; a screw bolt is arranged between the clamps. The central line of the transverse groove is crossed with the axis line of the shaft handle. Jaws of the clamps are in the shape of an inward isosceles right triangle, the closing jaws of the clamps are in the shape of a square, and the diagonal lines of the square are overlapped on the central line of the transverse groove. The utility model has the advantages that the utility model provides a simple clamp which rotates by using a neck shaft of a connecting rod as the central line; a semicircular heating quenching inductor can easily approach to the neck shaft of a connecting rod, and the neck shaft of a connecting rod of a crank shaft has an even profile quenching layer.
Description
Technical field
The utility model relates to a kind of anchor clamps, particularly a kind ofly is used for the eccentric fixture that small-sized bent axle is rotated quenching.
Background technology
When carrying out intermediate frequency or high-frequency quenching heat treatment process at rod journal place at present to the crankshaft type product, in order to obtain good quenched case and uniform surface hardness, preferably rod journal quenches in rotation, but rod journal is because its structural reason, be that the medullary ray of rod journal and the center of main shaft have certain distance, this distance is called eccentricity, when rotating if rotate around the alignment of shafts of a bent axle, then rod journal carries out circumferential motion around it, for small crankshaft, it is very big with the semicircle inductor block rod journal to be rotated the quenching difficulty, therefore need anchor clamps badly, it can clamp main journal makes rod journal center on self medullary ray rotation, makes the semicircle inductor block more stablely near rod journal, and to its even heating and quenching.
Summary of the invention
The purpose of this utility model is to solve in the prior art to produce difficult problem because of rod journal is in eccentric position when being rotated quenching, and a kind of eccentric fixture that small-sized bent axle is rotated quenching that is used for is provided.The utility model designs a kind of eccentric fixture that small-sized bent axle is rotated quenching that is used for, and comprises platform, footstalk, it is characterized in that: translot is arranged on platform, a pair of anchor clamps are arranged on translot, screw bolt between the anchor clamps.The medullary ray of translot and the axial line of footstalk intersect.Jaw on a pair of anchor clamps is the isosceles right triangle of indent, and the jaw after being harmonious of a pair of anchor clamps is a square, and foursquare diagonal lines intersection point coincides with the medullary ray of translot.The utility model has the advantages that provides one to be the simple and easy anchor clamps of medullary ray rotation with the rod journal, and semicircle heating quenching inductor block ratio is easier near rod journal, makes rod journal obtain the quenched case of even profiling.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing 1 is the utility model structural representation,
Accompanying drawing 2 is the utility model structure schematic top plan view,
Embodiment
Comprise platform 1, footstalk 2 among the figure, it is characterized in that: translot 3 is arranged on platform 1, a pair of anchor clamps 4 are arranged on translot 3, screw bolt 5 between the anchor clamps 4.The axial line of the medullary ray of translot 3 and footstalk 2 intersects.Jaw 6 on a pair of anchor clamps 4 is the isosceles right triangle of indent, jaw 6 after being harmonious of a pair of anchor clamps 4 is a square, foursquare intersection of diagonal coincides with the medullary ray of translot 3, and the distance at foursquare medullary ray and footstalk 2 centers is exactly the eccentricity of small crankshaft 7 (dotting among the figure).In use, small-sized bent axle 7 rod journals that will be quenched are in alignment with the axis of footstalk 2, then small-sized bent axle 7 main journals are inserted into and form a square jaw 6 after a pair of anchor clamps 4 are harmonious, tighten and screw bolt 5, jaw 6 after two anchor clamps 4 are harmonious is held the main journal of small-sized bent axle 7 tightly, at this moment, the semicircle inductor block enters the heating location of small-sized bent axle 7 rod journals, the central lines of the axial line of footstalk 2 and small-sized bent axle 7 axle journals, the eccentric fixture rotation, small-sized bent axle 7 is just around the rotation of its rod journal medullary ray, heats and quenches.
