Description

Technical Field

[0001] The utility model relates to the technical field of bearing rings, in particular to a bearing ring size measuring mechanism. Background Art

[0002] Bearings are commonly used parts in mechanical transmission. Bearings are mainly composed of inner ring, outer ring, newspaper rack, ball bearings, etc. The inner ring and outer ring are made of steel pipes. In order to ensure the service life of the bearing and the ease of rotation, the dimensions of the inner and outer rings of the bearing need to be accurately controlled to ensure the roundness of the inner and outer rings of the bearing.

[0003] In order to achieve accurate and convenient measurement of the height of the bearing ring lock, the prior art will use a corresponding measuring instrument for measurement, such as a measuring instrument for the lock of an angular contact ball bearing disclosed in the China Patent Network (CN211503910U). The measuring instrument includes a base, the base has a slide rail, and the micrometer is installed on the base through the slide rail. In order to install the measured bearing ring, the base is also provided with a V-shaped block capable of supporting the measured bearing ring, and a column is provided on the side of the V-shaped block, and a pressure block is provided on the column. When measuring, the bearing ring to be measured is pressed onto the V-shaped block by the pressure block, and the micrometer is driven to make the probe of the micrometer slide over the lowest and highest points of the lock, so as to achieve the measurement of the lock height.

[0004] However, bearings are generally produced in large quantities. When using this measuring instrument, each time a bearing ring is measured, the pressure block must be operated twice to complete the clamping and removal operations. The clamping and removal operations take a certain amount of time, affecting the efficiency of measuring and detecting the size of batch bearing rings. Utility Model Content

DETAILED DESCRIPTION

[0023] The utility model embodiment provides a bearing ring size measuring mechanism, such as Figure 1-5 As shown, it includes a receiving box 1, and a plurality of through circular grooves 11 are opened on the top of the receiving box 1. The circular grooves 11 are used to place bearing rings. Grooves 12 are symmetrically opened on both sides of the inner wall of the circular groove 11. A spring 13 is fixedly installed in the groove 12. A protrusion 14 is welded at one end of the spring 13. The protrusion 14 is slidably matched with the groove 12. One end of the protrusion 14 extends out from the groove 12 and enters the circular groove 11.

[0024] A slide rail 5 is suspended on the top of the receiving box 1, and the slide rail 5 is slidably matched with a sliding seat 1 6 and a sliding seat 2 8. An electric push rod 81 is fixedly installed at the bottom of the sliding seat 2 8, and a horizontal plate 9 is fixedly installed vertically downward on the electric push rod 81. A plurality of pillars 91 are welded at the bottom of the horizontal plate 9, and the pillars 91 correspond one by one to the circular grooves 11.

[0025] A collecting tank 3 is arranged below the receiving box 1 , and a vertical connecting rod is welded on the top of the collecting tank 3 , and the upper end of the connecting rod is used to support the receiving box 1 .

[0026] A slideway 4 is placed on the left side of the receiving box 1, a crossbar 2 runs through the right side of the receiving box 1, and a push plate 7 is slidably matched at the bottom of the slideway 5.

[0027] The lower end of the push plate 7 is conical in cross section, a tooth groove 71 is provided in the center of the push plate 7, a vertical upward slide groove 61 is provided at the bottom of the sliding seat 6, the push plate 7 slides in cooperation with the slide groove 61, a motor-driven gear 62 is fixedly installed in the slide groove 61, and the gear 62 is meshed with the tooth groove 71.

[0028] The support 91 and the circular groove 11 are arranged in concentric circles, the diameter of the support 91 is 0.5 cm, and the diameter of the circular groove 11 is 1 cm.

[0029] The top of one end of the protrusion 14 extending into the circular groove 11 is a curved surface. The rotation of the gear drives the push plate 7 to move up and down. When the push plate 7 drops to the lowest point, the lower end of the push plate 7 contacts the top of the receiving box 1.

[0030] Working principle: Multiple bearing rings are laid flat on the receiving box, and the sliding seat 6 drives the push plate 7 to move from right to left. During this process, the bearing rings fall into the circular groove 11, and the excess bearing rings are swept into the slideway 4 by the push plate 7. The bearing rings that fall into the circular groove 11 are received by the protrusion 14.

[0031] Then the sliding seat 2 8 moves to cover the circular groove 11 with the horizontal plate 9, and the pillar 91 is arranged concentrically with the circular groove 11. Then, the electric push rod 81 extends to extend the pillar 91 into the circular groove 11.

[0032] If the inner diameter of the bearing ring is smaller than the support 91 , the bearing ring is considered to be of a partially standard size. At this time, the support 91 squeezes the bearing ring, and the protrusion 14 is pressed into the groove 12 , causing the bearing ring to fall out of the circular groove 11 and into the collecting groove 3 .

[0033] If the bearing ring is of standard size, the support post 91 passes through the bearing ring.

[0034] After the bearing rings are screened, the receiving box 1 is pushed to move along the cross bar 2, and the receiving box 1 is turned over to pour out the qualified bearing rings.

[0035] In summary, the bearing ring size measuring mechanism is composed of a receiving box 1, 5 slide rails, 6 sliding seat 1, 7 push plates, 8 sliding seat 2, 81 electric push rods, 9 horizontal plates, and 91 pillars. A circular groove 11 is provided on the receiving box 1, and a convex block 14 is slidably fitted in the circular groove 11. The bearing ring falling into the circular groove 11 is received by the convex block 14. The bearing ring is screened by the cooperation of the pillar 91, the circular groove 11, and the convex block 14, and unqualified bearing rings are squeezed out of the circular groove 11, thereby reducing unnecessary operating steps, and multiple bearing rings can be detected at one time, further accelerating the efficiency of size detection.
