Description

Technical Field

[0001] The utility model relates to the technical field of bearing detection, in particular to a detection device for bearing production. Background Art

[0002] At present, bearings are an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The bearing ring is an annular part of a radial rolling bearing with one or more raceways. The contour of the bearing ring assembly needs to be detected after processing.

[0003] The existing method for measuring the roundness of a bearing is usually to manually measure the outer diameter of the bearing using a caliper. In order to facilitate multiple measurements to ensure measurement accuracy, not only is the detection effect poor, but the detection efficiency is also reduced. Utility Model Content

[0005] The utility model is implemented by the following technical scheme: a detection device for bearing production, comprising an operating table, a servo motor is fixedly installed on one side of the operating table, and a limiting mechanism is arranged inside the operating table for fixing bearings of different models, a mounting plate is fixedly connected to one side of the operating table, and a detection mechanism is slidably connected inside the mounting plate for detecting the outer diameters of bearings of different heights.

[0006] As a further improvement of the above scheme, the limiting mechanism includes a bidirectional screw rotatably installed inside the operating table, a movable block is mirror-engaged in the middle of the bidirectional screw, a fixed plate is arranged on the top of the movable block, and a limiting plate corresponding to the bearing is arranged on one side of the fixed plate.

[0007] Through the above technical solution, the bidirectional screw is driven to rotate by the rotation of the servo motor, so that the movable block drives the fixed plate and the limit plate to slide outward at the same time, and the bearing is fixed from the inside. Bearings with different inner diameters can be fixed to prevent displacement during detection and affect the accuracy of the detection results.

[0008] As a further improvement of the above solution, a first sliding groove is provided inside the operating table, and the movable block slides inside the first sliding groove.

[0009] As a further improvement of the above solution, a first cylinder is fixedly installed on the top of the movable block, an output end of the first cylinder is fixedly connected to the fixed plate, and a second sliding groove for sliding of the first cylinder is provided on the upper surface of the operating table.

[0010] Through the above technical solution, by setting the first cylinder, the fixing plate and the limiting plate can be driven to move up and down, so that bearings of different heights can be fixed, which is practical.

[0011] As a further improvement of the above solution, the top of the fixed plate is fixedly connected to the limiting plate through a telescopic rod, and a spring that simultaneously connects the limiting plate and the fixed plate runs through the inside of the telescopic rod.

[0012] Through the above technical solution, by setting the telescopic rod and the spring, the limit plate is made to fit the inner wall of the bearing to be detected, further expanding the application range of the detection device.

[0013] As a further improvement of the above-mentioned scheme, the detection mechanism includes a third slide groove opened on the front surface of the mounting plate and a knob threadedly connected to the top of the mounting plate, the bottom of the knob is fixedly connected to a slider sliding inside the third slide groove, a second cylinder is fixedly installed on one side of the slider, the output end of the second cylinder is fixedly connected to a fixed block, and a micrometer is fixedly installed on the top of the fixed block.

[0014] Through the above technical solution, the knob is turned to drive the slider to slide in the third slide groove, and the height of the micrometer is adjusted to facilitate the use of bearings of different heights. At the same time, the use of the second cylinder enables the micrometer to be used with bearings of different outer diameters, which is practical.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The utility model drives the two-way screw connected to the servo motor to rotate through the rotation of the servo motor, so that the movable block drives the fixed plate to drive the limit plate to slide to both sides to fix the bearing. The telescopic rod and the spring are arranged so that the limit plate fits the inner wall of the bearing to be tested. The knob is turned so that the knob drives the slider to slide in the third slide groove to adjust the height between the micrometer and the bearing, and then the second cylinder is controlled to drive the micrometer to contact the outer diameter of the bearing. The design can detect bearings of different models, effectively reduce detection errors, and improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
