Abstract
The utility model discloses a tension pulley detecting device, which solves the problems that during the production process of the prior tension pulley, the quality of the tension pulley is checked only by the work experience of the operators, so that the stability and the service life of the tension pulley cannot be effectively ensured during the work process. The tension pulley detecting device comprises a work platform, and is characterized in that the work platform is provided with a male die which is matched with a trapezoid hole on the tension pulley, and the work platform is provided with an upright post which is matched with a fixed hole on the tension pulley, and the relative position between the upright post and the male die corresponds to that between the fixed hole and the trapezoid hole on the tension pulley.
Description
Technical field
The utility model relates to a kind of pick-up unit that stretching pulley is detected of can be used for.
Background technology
Stretching pulley is to be used for a kind of parts that the tensioning degree of driving-belt is controlled, and it is to be assemblied on the body of engine, and its wheel face is resisted against on the outside surface of driving-belt.The structure of stretching pulley comprises bearing, lasso and fixed mount, and lasso is arranged in the inner ring of bearing, and fixed mount and lasso link together by the mode of punch riveting.The bearing inner race center position is provided with a mounting hole, after stretching pulley is assemblied on the body, this mounting hole is socketed in the limited post set on the body with gap, the outer end of fixed mount is provided with fixed orifice, the bearing that rivets together with support with this hole be the center, to be socketed in limited post set on the body with mounting hole be the radius swing, just can adjust the degree that compresses of stretching pulley and driving-belt, also be tensile force.Because stretching pulley is to be formed by above-mentioned each separate component-assembled, working method in conjunction with stretching pulley, have certain requirement for the relative rigging position between each parts of forming stretching pulley, otherwise can have influence on the serviceable life of stretching pulley and the adjustment of stretching pulley.And present in the production and assembling process of stretching pulley, the pick-up unit of stretching pulley quality does not appear being used to detect.Quality examination for stretching pulley just utilizes operative employee's working experience to determine, the working experience difference between the different operating worker is bigger, and the quality of production that this can not control stretching pulley well also is prone to batch character amount problem of product.
Summary of the invention
The utility model technical issues that need to address are: a kind of stretching pulley pick-up unit is provided, and it can carry out quality testing to the stretching pulley in the production run, is convenient to the quality of stretching pulley is controlled.
For solving described problem, the technical solution of the utility model: a kind of stretching pulley pick-up unit, comprise worktable, it is characterized in that, be provided with on the worktable be used for stretching pulley on the punch that matches of mounting hole, be provided with on the worktable be used for stretching pulley on the column that matches of fixed orifice, relative position between described column and the punch and the fixed orifice on the stretching pulley and the relative position between the mounting hole are corresponding.The correlation parameter of the relative position relation of described punch and column and the stretching pulley of a standard is corresponding, when stretching pulley is detected, mounting hole on the stretching pulley inner ring is socketed on the punch, fixed orifice on the fixed mount is socketed on the column, thereby can determine the relative position between the fixed orifice on mounting hole and the fixed mount, and then can determine the relative position relation between fixed mount and the lasso.
As preferably, described worktable is provided with discoid boss, and described punch and column all are arranged on the boss.Described punch can be determined shape and position according to the division center on the bearing inner race, and punch and column all are arranged on the boss, is convenient to tensioning is detected.
As preferably, described punch is waist shape.The punch of waist shape be convenient to inner ring on mounting hole match so that whether detect this mounting hole qualified.
As preferably, described worktable is provided with some columniform gauges, and the external diameter of each gauge is different.These gauges are used to detect fixed orifice on the fixed mount whether in the error range that allows.
As preferably, described worktable is provided with support, is provided with indicating gauge on support.This indicating gauge is used to detect bearing height overall on the stretching pulley after assembling, assembles the groove position of high equal altitudes, the every height that detects fixed mount, detection lasso seal groove, detects parameters such as the lasso height and the degree of depth
Compared with prior art, the beneficial effects of the utility model are embodied in:
Utilize this stretching pulley pick-up unit to detect to fixed mount on the stretching pulley and the relative position between the lasso, and whether the shape of mounting hole met the requirements differentiate, be convenient to produce qualified stretching pulley, guaranteed the stability and the serviceable life of stretching pulley work.
Description of drawings
Fig. 1 is the front view of this stretching pulley pick-up unit.
Fig. 2 is the vertical view of this stretching pulley pick-up unit.
Embodiment
Below in conjunction with Fig. 1, Fig. 2 the utility model stretching pulley pick-up unit is described further.
The structure of the utility model stretching pulley pick-up unit comprises worktable 1, is provided with discoid boss 2 on worktable 1, and boss 2 is provided with outstanding punch 10, and punch 10 is waist shape, also is provided with columniform column 5 on boss 2.
The structure of described stretching pulley 4 comprises bearing, lasso, fixed mount 6, and lasso is pressed in the inner ring of bearing, and the bearing inner race center position is provided with mounting hole, and fixed mount 6 is riveted together with lasso, is provided with fixed orifice 9 in the outer end of fixed mount 6.
Relative position between the fixed orifice 9 on the relative position between above-mentioned punch 10 and the column 5 and the stretching pulley of a standard on mounting hole and the fixed mount 6 is corresponding.
Also be provided with four columniform gauges 3 on worktable 1 vertically, the external diameter of these four gauges 3 has nothing in common with each other.These four gauges 3 are divided into two groups, and every group of gauge is two.The external diameter of a gauge is more smaller than the diameter of the fixed orifice 9 on a certain specification stretching pulley in every group, and the external diameter of another root gauge is than the slightly larger in diameter of described fixed orifice 9.By make on the stretching pulley 4 fixed orifice 9 respectively with one group in two gauges 3 carry out socket, whether the diameter that promptly can draw the fixed orifice 9 on a certain stretching pulley 4 meets dimensional requirement.
Also be provided with support 8 on the worktable 1, on support 8, be provided with indicating gauge 7.This indicating gauge 7 can be used for detecting the parameters such as groove position, detection lasso height and the degree of depth of punching press rear bearing height overall, the high equal altitudes class of assembling, the every height that detects fixed mount, detection lasso seal groove.
