Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] See also Figure 1-2The utility model provides a ring roundness detection mechanism, comprising: a base plate 1 for placing a bearing ring, a rotating mechanism arranged above the base plate, and a roundness detection mechanism arranged below the base plate. Specifically, the roundness detection mechanism comprises a bracket plate 2, a partition plate 3 arranged on the bracket plate, a plurality of guide columns 4 penetrating the partition plate and arranged in parallel on the bracket plate, a left guide sleeve 5 and a right guide sleeve 6 sleeved on the guide columns and located on both sides of the partition plate, a left measuring slide 7 connected to one end of the left guide sleeve, a right measuring slide 8 connected to one end of the right guide sleeve, a left outer diameter measuring claw 9 arranged at the top of the left measuring slide, and a right outer diameter measuring claw arranged at the top of the right measuring slide. Claw 10, wherein the two ends of multiple groups of guide columns are connected to the two sides of the bracket plate, the left guide shaft sleeve and the right guide shaft sleeve are mounted on the guide column and the middle area is separated by a partition plate, the left measuring slide and the right measuring slide are connected by multiple groups of elastic members 11, wherein the elastic members are reset springs, and 3-4 groups can be set according to needs. Under the pulling force of the reset spring, the left measuring slide and the right measuring slide are in a state of approaching each other, a measuring limit block 12 is installed in the middle of the left measuring slide, and a roundness measuring sensor 13 is installed at the corresponding position on the right measuring slide, and the front end of the roundness measuring sensor is in contact with the measuring limit block, so as to better detect the roundness of the product.

[0016] Specifically, a spreading mechanism is provided under the bracket plate, which is used to drive the bracket plate to move upward and adjust the spacing between the left outer diameter measuring claw and the right outer diameter measuring claw to facilitate clamping the bearing ring to be tested. The spreading mechanism includes a first cylinder connecting plate 14 connected to the bracket plate, an upward pushing cylinder 15 provided on the first cylinder connecting plate, a left and right spreading cylinder 16 connected to the output end of the upward pushing cylinder, and a left shift fork 17 and a right shift fork 18 provided on the left and right spreading cylinders.

[0017] When working, the left and right shift forks installed on the left and right opening cylinders stretch the left measuring slide and the right measuring slide, driving the left outer diameter measuring claw and the right outer diameter measuring claw to separate a certain distance, and pushing the cylinder upward pushes the entire roundness detection mechanism to the specified detection position, and the middle partition plate can be accurately positioned. When the left outer diameter measuring claw and the right outer diameter measuring claw are pushed to the measuring position, the left and right opening cylinders retract and return to their original positions, and the multiple sets of reset springs installed on the left and right measuring slides can make the left and right outer diameter clamping jaws fit on the outer diameter of the bearing ring 25 to be detected. At this time, pushing the cylinder downward starts to push the rotating cylinder downward to the specified position, and the left and right spreading claws arranged on the rotating cylinder extend into the interior of the bearing ring and tighten the bearing ring. The rotating cylinder starts to drive the bearing ring to rotate 360 degrees at a uniform speed, and the left measuring slide and the right measuring slide transmit the displacement caused by the outer diameter deformation of the bearing ring during rotation to the roundness measurement sensor and the measuring limit block, which cooperate to detect the outer diameter roundness size of the bearing ring.

[0018] In order to facilitate the smooth rotation of the bearing ring in the left outer diameter measuring jaw and the right outer diameter measuring jaw, ball grooves are opened on the inner side walls of the two jaws, and balls 26 in contact with the bearing ring are placed in the ball grooves.

[0019] The beneficial effects of the utility model are: it can measure the roundness of the outer diameter of the bearing ring during the heat treatment process, and with the automatic loading and unloading structure, it can realize automatic detection and sorting of the diameter size of the bearing ring, with the advantages of low positioning requirements, high detection accuracy, fast detection speed, etc., thereby improving production efficiency.
