Description

Technical Field

[0001] This utility model belongs to the field of workpiece inspection technology, and in particular relates to a workpiece height and parallelism detection mechanism. Background Technology

[0002] Bearings are indispensable components in modern machinery. Their main functions are to support rotating parts, reduce friction during movement, and ensure rotational accuracy. With the rapid development of modern industry, the precision requirements for bearings in various machines are becoming increasingly stringent. Bearing height and parallelism, as important indicators affecting bearing precision, directly relate to bearing performance and the overall operational efficiency of the machinery.

[0003] Traditional methods for inspecting the height and parallelism of bearing inner rings often involve manual measurement using tools such as calipers and micrometers. This approach is not only time-consuming and labor-intensive, resulting in low production efficiency, but it is also susceptible to human error, leading to significant measurement errors. Clearly, it suffers from both low inspection efficiency and poor accuracy. Utility Model Content

[0004] The purpose of this invention is to provide a workpiece height and parallelism detection mechanism to solve the problems of low detection efficiency and poor detection accuracy in conventional manual detection methods in the prior art.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A workpiece height and parallelism detection mechanism includes a detection frame and at least one set of detection parts, wherein:

[0007] The inspection frame is provided with at least one inspection station, and each inspection station is provided with an inspection platform. Each inspection station corresponds to a set of inspection parts. The inspection platform is configured to horizontally support the workpiece to be inspected. The inspection part includes an inspection drive, a lifting frame, an inspection pressure rod, and an inspection assembly. The lifting frame is vertically mounted on the inspection frame and located directly above the inspection platform. The fixed end of the inspection drive is mounted on the inspection frame, and the driving end of the inspection drive is connected to the lifting frame. The inspection drive is configured to drive the lifting frame to a high position or a low position.

[0008] The detection assembly is mounted on the detection frame and located above the lifting frame when it is in a high position. The detection assembly includes a displacement sensor with the detection end facing downwards. The length of the detection pressure rod is greater than the diameter of the workpiece. The detection pressure rod is configured to detect the flatness of the workpiece. The detection pressure rod is mounted at the bottom of the lifting frame. The detection drive unit drives the detection pressure rod to descend to a low position through the lifting frame, so that the two ends of the detection pressure rod along its own length press against the detection surface of the workpiece to be detected, thereby cooperating with the displacement sensor to detect the height and flatness of the workpiece to be detected.

[0009] Furthermore, the detection unit is provided in two sets, and the detection frame is provided with two detection stations. The extension directions of the two detection pressure rods of the two sets of detection units are perpendicular.

[0010] Furthermore, the testing frame is also equipped with a calibration component, which includes a calibration platform and a calibration drive. The calibration platform is configured to carry a standard workpiece. The fixed end of the calibration drive is mounted on the testing frame, and the driving end of the calibration drive is connected to the calibration platform. The calibration drive is configured to drive the calibration platform closer to or further away from the testing station. The calibration drive drives the calibration platform to move to the testing station. The testing pressure rod presses against the testing surface of the standard workpiece at both ends along its own length to calibrate the standard workpiece before testing the workpiece to be tested.

[0011] Furthermore, the lifting frame includes a lifting block and a connecting block. The top of the connecting block is installed on the driving end of the detection drive component. A track groove is formed in the middle of the connecting block. A track wheel is installed on the side of the lifting block facing the connecting block. The track wheel is adapted to the track groove and is installed in the track groove.

[0012] Furthermore, a sliding pair is provided between the lifting block and the detection frame. The sliding pair includes a linear guide rail and a slider. The linear guide rail extends along the height direction and is laid on the detection frame. The slider is fixed on the lifting block and slidably sleeved on the linear guide rail.

[0013] Furthermore, the detection drive is detachably mounted on the detection frame via a mounting plate. The fixed end of the detection drive is mounted on the side of the mounting plate facing the detection station. The side of the mounting plate away from the detection station is adjustablely mounted on the detection frame. The detection frame has a first adjustment scale along the height direction, and the mounting plate has a second adjustment scale adapted to the first adjustment scale.

[0014] Furthermore, the detection pressure rod is mounted on the bottom of the lifting block via a clamping assembly. The clamping assembly includes two spaced-apart clamping blocks. The first ends of the two clamping blocks are mounted on the lifting block, and a clamping area for clamping the detection pressure rod is formed between the second ends of the two clamping blocks. The middle portions of the two clamping blocks are detachably connected via a mounting member.

[0015] Furthermore, the displacement sensor is fixedly connected to the detection frame via a connecting plate, which is an "L"-shaped connecting plate. The first end of the "L"-shaped connecting plate is detachably mounted on the detection frame, and the displacement sensor is mounted on the second end of the "L"-shaped connecting plate.

[0016] Furthermore, the calibration component also includes a limiting plate, the top of which is mounted on the side of the calibration platform away from the testing station, and the bottom of which extends outwards. The limiting plate is configured to limit the travel of the calibration platform when it moves.

[0017] Furthermore, the top end of the clamping assembly is fixedly connected to the bottom of the lifting block via a connecting shaft.

[0018] Compared with existing technologies, the advantages of the workpiece height and parallelism detection mechanism are as follows:

[0019] 1) By cooperating with the detection drive unit, the lifting frame, the detection pressure rod and the displacement sensor, the detection drive unit drives the detection pressure rod to descend to the low position through the lifting frame, so that the two ends of the detection pressure rod along its own length press against the detection surface of the workpiece to be detected. Then, in conjunction with the displacement sensor, the height and flatness of the workpiece to be detected are detected. The detection method is not only convenient and easy to implement, but also has high detection efficiency and high detection accuracy.

[0020] 2) By setting up two sets of detection units, two workpieces can be detected at the same time. At the same time, the extension direction of the two detection pressure rods of the two sets of detection units is set to be perpendicular, which further improves the detection efficiency and detection accuracy.

[0021] 3) By setting up a calibration component, the standard workpiece can be calibrated before the workpiece to be inspected, thereby further improving the inspection accuracy. Attached Figure Description
