Description

Technical Field

[0001] The utility model relates to the technical field of bearing end surface detection, in particular to a bearing end surface height detection mechanism. Background Art

[0002] The bearing end face refers to one of the two planes of the bearing, which is usually used to contact the adjacent parts. A bearing usually has two end faces, located at the ends of the inner ring and the outer ring. Bearing end face height detection refers to measuring the vertical distance from the bearing end face to the adjacent parts. This measurement is usually used to ensure that the bearing is installed in the correct position to ensure the normal operation and performance of the mechanical system. The measurement of the bearing end face height is usually based on the measurement accuracy requirements and budget. The appropriate measurement tools (such as micrometers, block gauges, laser rangefinders, image measurement systems, etc.) are selected to obtain accurate measurement data.

[0003] However, the existing bearing end face height detection mechanism needs to fix the bearing by pressing down the positioning tool. When there is a large deviation between the center of the bearing placed on the detection table and the center of the positioning tool, the positioning tool will squeeze the bearing when pressing down, causing the bearing to be unevenly stressed as a whole and cause it to warp. It cannot ensure that the bearing end face remains horizontal or vertical, thereby affecting the detection accuracy of the measuring pen for the bearing end face height. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the utility model provides a bearing end face height detection mechanism, which can solve the problem that when the positioning tool presses down to fix the bearing, the overall force of the bearing is uneven and the bearing will warp, resulting in the bearing end face being unable to maintain a horizontal or vertical state, thereby affecting the detection accuracy of the bearing end face height by the measuring pen. The utility model can quickly locate the center of the bearing, ensure that the bearing is evenly stressed and maintains a horizontal or vertical state, avoid affecting the detection accuracy of the bearing end face height by the measuring pen, and at the same time perform integrated fixing and detection of the bearing, thereby improving the detection efficiency.

[0006] (II) Technical solution

[0007] To achieve the above object, the utility model provides the following technical solutions: a bearing end surface height detection mechanism, comprising a frame and a measuring assembly connected to the frame, wherein the lower end of the frame is fixedly connected to a base, the outer surface of the frame is sleeved with a linear bearing, the linear bearing and the measuring assembly are connected to each other, and the upper end of the measuring assembly is installed with a cylinder;

[0008] A slide groove is provided inside the base, a limit block is arranged inside the slide groove, a support plate is fixedly connected to the lower surface of the limit block, a rotating shaft is arranged inside the support plate, a gear is sleeved on the outer surface of the rotating shaft, a driving block is fixedly connected to the upper end of the rotating shaft, racks are respectively meshed and connected on both sides of the gear, a fixing rod is fixedly connected to the upper surface of the rack, and a positioning block is connected to one side of the fixing rod.

[0009] Through the above technical solution, the cylinder drives the measuring component to rise and fall, so that the positioning tooling and measuring pen connected to the measuring component can be adjusted in position. The bearing can be quickly fixed by the positioning tooling, and the bearing end face height can be detected with high precision by the measuring pen, thereby greatly improving the detection efficiency of the bearing end face height.

[0010] Furthermore, the measuring component is lifted and lowered along the frame via a linear bearing, and two linear bearings are provided.

[0011] Through the above technical solution, the use of linear bearing guidance can ensure the verticality of the movement of the positioning tooling and the measuring pen driven by the measuring component, which is beneficial to improving the accuracy of bearing end face height detection.

[0012] Furthermore, a positioning tool and a measuring pen are connected to one side of the measuring component, and the measuring pen is connected to the measuring component in a sliding manner.

[0013] Through the above technical solution, the measuring pen can slide inside the measuring component to adjust its position and contact the end face of the bearing, so as to facilitate the end face height detection of bearings of different sizes and meet various detection needs.

[0014] Furthermore, the support plate and the base are connected in a sliding manner, and the size of the support plate is smaller than that of the base.

[0015] Through the above technical solution, the support plate can be pushed and pulled to slide inside the base, making it convenient to store the support plate inside the base, thereby reducing the space occupied by the detection mechanism.

[0016] Furthermore, two racks are provided, and the racks are centrally symmetrically distributed about the center of the gear, and the racks are connected to the support plate by sliding connection.

[0017] Through the above technical solution, the rotating gear can make the two racks move in opposite directions, so as to adjust the position of the racks. The racks drive the positioning blocks connected to the fixed rods to move synchronously, which is conducive to the positioning blocks to position bearings of different sizes.

[0018] Furthermore, the sum of the heights of the rack and the fixing rod is greater than the height of the support plate, and the fixing rod is an inverted "L"-shaped structure when viewed from the front.

[0019] Through the above technical solution, it is convenient for the fixing rod to extend from the inside of the support plate so that the fixing rod is located above the support plate. The positioning block connected to the fixing rod can perform preliminary positioning of the bearing, which is convenient for quickly positioning the center of the bearing, thereby ensuring that the bearing is correctly placed and that when the positioning tool presses down the bearing to fix it, the overall force on the bearing is uniform, thereby ensuring that the end face of the bearing remains horizontal or vertical, which is conducive to ensuring the accuracy of the subsequent measuring pen's detection of the bearing end face height.

[0020] Furthermore, the positioning block is connected to the fixing rod in a fixed manner, and the positioning block has an arc-shaped structure when viewed from above.

[0021] The above technical solution facilitates the fitting of the positioning block and the curved surface of the bearing, thereby improving the stability of the initial positioning of the bearing.

[0022] Compared with the prior art, the utility model provides a bearing end surface height detection mechanism, which has the following beneficial effects:

[0023] In the utility model, the rotation of the driving gear can make the two racks move in opposite directions, and then the positioning block connected to the fixed rod can quickly position the center of the bearing, thereby ensuring that the position of the bearing is correctly placed, so that when the positioning tool presses down the bearing to fix it, the bearing is evenly stressed as a whole, and the phenomenon of the bearing tilting is avoided. By ensuring that the end face of the bearing remains in a horizontal or vertical state, it is beneficial to ensure the accuracy of the subsequent measuring pen in detecting the height of the bearing end face, and the cylinder drives the measuring component to rise and fall. While the positioning tool fixes the bearing, the measuring pen can perform high-precision detection of the height of the bearing end face, thereby greatly improving the detection efficiency of the bearing end face height.

Two racks 14 are provided. The racks 14 are centrally symmetrically distributed about the center of the gear 12. The racks 14 are connected to the support plate 10 by a sliding connection.
