Abstract
The utility model relates to a detecting device for deep groove ball bearing ring raceways. The detecting device comprises a detecting frame which is fixedly provided with a first detecting rod and slidably provided with a second detecting rod, detecting head ends of the two detecting rods extend out of the detecting frame in a suspended form, detecting heads of the two detecting rods are disposed oppositely, a sliding direction of the second detecting rod is parallel to a connecting line between the detecting heads of the two detecting rods, and the second detecting rod is provided with a detecting meter. The detecting frame is a door-shaped frame, and two side frames of the door-shaped frame are two detecting arms correspondingly. When the detecting device is utilized for detecting size of a super-huge type deep groove ball bearing ring raceway, the detecting head of the first detecting rod is a supporting point located at the position of the outer diameter corresponding to the bottom of the raceway, the detecting head of the second detecting rod is located on the bottom of the raceway, the supporting point keeps fixed, the detecting head of the second detecting rod is swayed up, down, left and right, the minimum value displayed by the detecting meter is read and compared with a standard gauge block, and reading of the minimum value is a wall thickness value of the raceway.
Description
Technical field
The utility model relates to a kind of super-huge deep groove ball bearing lasso raceway groove pick-up unit.
Background technology
The raceway groove of deep groove ball bearing lasso is a curved surface, owing to there is not special-purpose testing tool at present, therefore can't directly detect wall thickness, existing super-huge deep groove ball bearing outer ring raceway dimension detection method is that utilization outside micrometer folder steel ball is measured, but for the bigger lasso in ditch position, the crossbeam of outside micrometer can interfere and can't detect with ring face.
The utility model content
The purpose of this utility model provides a kind of deep groove ball bearing lasso raceway groove pick-up unit, to solve the measurement difficult problem of the bigger super-huge deep groove ball bearing lasso channel dimensions in ditch position.
For achieving the above object, the utility model adopts following technical scheme: deep groove ball bearing lasso raceway groove pick-up unit, this pick-up unit comprises testing stand, be fixed with first test rod on the testing stand, slidable fit has second test rod, the gauge head end of the two test rods testing stand that overhangs out, the gauge head of two test rods is oppositely arranged, and the glide direction of second test rod is parallel with the line of the gauge head of two test rods, on second test rod measuring instrument is housed.
Described testing stand has two parallel relative detection arm, described first, second test rod is straight-bar, first inspection, the second test rod correspondence vertically are installed on the relevant detection arm, second test rod slides and is installed on the relevant detection arm, the afterbody of second test rod stretches out detection arm, and described measuring instrument is installed in the tail end of second test rod.
Described testing stand is a door-shaped frame, and the both sides frame of door-shaped frame corresponds to two detection arm.
When utilizing the utility model to detect super-huge deep groove ball bearing lasso channel dimensions, the gauge head of first test rod is a fulcrum, this fulcrum is positioned at position corresponding with bottom of trench on the external diameter, the gauge head of second test rod is positioned at trench bottom, keep fulcrum motionless, the gauge head of second test rod is rocked in upper and lower, left and right, reads the shown minimum value of measuring instrument, this minimum value and standard gauge block compare, and its reading is wall thickness value.The utility model adopts door-shaped frame formula testing stand, and the rigidity of device is good, and it is more accurate to detect data.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the schematic diagram that utilizes the utility model to detect.
Embodiment
Figure 1 shows that deep groove ball bearing lasso raceway groove pick-up unit, this pick-up unit comprises testing stand 1, testing stand 1 adopts door-shaped frame, the parallel relative both sides frame of door-shaped frame is a detection arm, be fixed with first test rod 2 on one of them detection arm, slide on another detection arm and be coated with second test rod 3, this two test rod is the straight-bar perpendicular to detection arm, the gauge head end of two test rods is with in opposite directions the mode detection arm that overhangs out, the gauge head of two test rods is oppositely arranged, the afterbody of second test rod 3 stretches out detection arm, and the tail end of second test rod is equipped with measuring instrument 4.
It is as follows to utilize the utility model to detect the step of super-huge deep groove ball bearing lasso channel dimensions:
1. measure the external diameter value D of certain on the external diameter of lasso raceway groove bottom of trench position correspondence, and measurement point A, B are made marks respectively.
2. measure wall thickness value H1, H2 between A on outer raceway groove and the external diameter, the B gauge point respectively with this pick-up unit.
During detection, the gauge head of first test rod is a fulcrum, this fulcrum is positioned at position corresponding with bottom of trench on the external diameter, the gauge head of second test rod is positioned at trench bottom, keep fulcrum motionless, the gauge head of second test rod is rocked in upper and lower, left and right, reads the shown minimum value of measuring instrument, this minimum value and standard gauge block compare, and its reading is wall thickness value.
3. external diameter value D deducts the numerical value that wall thickness value H1, H2 institute value is outer raceway groove.
4. according to above method, along the circumferential direction measure many places, and will calculate gained outward maximum, the minimum value of raceway groove average, mean value is the size value of outer raceway groove.
Use super-huge deep groove ball bearing outer ring that this detection method processes and the play after the inner ring trap after testing all in acceptability limit, and this detection method is more convenient, quick.
