Description
Technical Field
The utility model belongs to bearing holder detection area especially relates to utensil is examined to tapered roller bearing holder tip protrusion volume.
Background
The bearing is an important part in the modern mechanical equipment, and the main function of the bearing is to support a mechanical rotating body, reduce the friction coefficient in the movement process of the mechanical rotating body and ensure the rotation precision of the mechanical rotating body.
The bearing works under the conditions of high temperature and high speed, has high requirements on the aspects of precision, rotating speed, vibration noise and the like, and the protruding amount and the recessed amount of the bearing must be accurately measured to meet the requirements.
The protrusion amount refers to the distance of the end face of the inner ring protruding out of the end face of the outer ring at the same end face under the action of the expected load of the bearing.
SUMMERY OF THE UTILITY MODEL
The utility model provides an utensil is examined to tapered roller bearing holder tip protrusion volume selects the holder that surpasss tip protrusion volume maximum value fast, and it is convenient, reliable to detect, the utility model discloses a following technical scheme realizes: the method comprises the following steps: the novel retainer comprises a base, two side plates and a top plate, wherein the two side plates are installed on the base, the top plate is installed at the other ends of the two side plates, the lower surface of the top plate is parallel to the upper surface of the base, the upper surface of the base is an inclined surface, the middle part of the upper surface of the base is a step with the inclined surface, and the depth of the step is the maximum value of the small-end protruding amount of the retainer.
Preferably, the inclined surface of the upper surface of the base inclines towards the discharge hole along the feed inlet, and the inclination angle is 30-45 degrees.
Preferably, the width of the step is not more than the diameter of the inner ring at the small end of the cage.
Preferably, the opposite side surfaces of the two side plates are vertical surfaces, the side plates are fixed on the side surface of the base through bolts, and the distance between the two side plates is larger than the outer diameter of the large end of the retainer.
Preferably, the top plate is fixed at the upper ends of the two side plates through bolts, and the distance between the top plate and the base is equal to the maximum value of the distance from the small end to the large end of the retainer.
The utility model has the advantages that: the checking fixture is used for detecting the small-end protrusion of the retainer, the maximum allowable protrusion of the small end is used as the depth of a step of the mold, the detection surface of the step is made into an inclined plane, so that a product to be detected can freely fall, the product to be detected is placed into the feed inlet during detection, if the product can pass through the checking fixture, the product is qualified, and on the contrary, the product to be detected is unqualified if the checking fixture does not pass through the product to be detected, and the checking efficiency is high.
Drawings
FIG. 1 is a schematic structural diagram of the present patent application;
FIG. 2 is a cross-sectional view A-A of FIG. 1;
in the figure, 1, a base; 2. a side plate; 3. a top plate; 4. a step; 5. and (5) products to be detected.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, the present invention includes: the holder comprises a base, two side plates and a top plate, wherein the two side plates are arranged on the base, the top plate is arranged at the other ends of the two side plates, the lower surface of the top plate is parallel to the upper surface of the base, and the base, the two side plates and the top plate form a channel for the holder to pass through; the upper surface of the base is an inclined surface, the lower surface of the top plate is always parallel to the upper surface of the base, and the inclined surface can ensure that the retainer can freely slide out of the channel; the middle part of the upper surface of the base is provided with a step with an inclined surface, the depth of the step of the inner ring at the small end of the retainer is the maximum value of the protrusion amount of the small end of the retainer, and when the protrusion amount exceeds the maximum value, the inner ring at the small end of the retainer cannot contact the inclined surface of the step and cannot slide out along the inclined surface.
Preferably, the inclined plane of the upper surface of the base inclines towards the discharge hole along the feed inlet, the inclination angle is 30-45 degrees, and the retainer slides out from the feed inlet towards the discharge hole.
Preferably, the width of the step is not more than the diameter of the inner ring at the small end of the cage.
Preferably, the opposite side surfaces of the two side plates are vertical surfaces, the side plates are fixed on the side surface of the base through bolts, and the distance between the two side plates is larger than the outer diameter of the large end of the retainer, so that the retainer is prevented from being clamped in the channel.
Preferably, the top plate is fixed at the upper ends of the two side plates through bolts, and the distance between the top plate and the base is equal to the maximum value of the distance from the small end to the large end of the retainer, so that the retainer can be guaranteed to slide out.
The checking fixture is used for detecting the small-end protrusion of the retainer, the maximum allowable protrusion of the small end is used as the depth of the step, the detection surface of the step is made into an inclined plane, so that a product to be detected can freely fall, the product to be detected is placed into the feed inlet during detection, if the product can pass through the checking fixture, the product is qualified, and on the contrary, the product to be detected is unqualified if the checking fixture does not pass through the product to be detected, and the checking efficiency is high, convenient and reliable.
Finally, it should be noted that: the above embodiments are only used for illustrating but not limiting the technical solutions of the present invention, and although the present invention is described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that: modifications and equivalents may be made thereto without departing from the spirit and scope of the invention, and the appended claims are intended to cover such modifications and equivalents as fall within the spirit and scope of the invention.
