Description

Technical Field

[0001] This utility model relates to a device for measuring the bore diameter of a bearing. Background Technology

[0002] During bearing production, it's crucial to ensure the bearing races have a specific bore diameter and roundness. Existing technologies offer various methods for measuring bore diameter, such as using a claw-type measuring head that senses the bore size through displacement. However, this contact-based method is ineffective for flexible bearings, as the bearing deforms when the measuring head moves, making accurate bore diameter measurement impossible. Pneumatic measuring instruments are also available for bore diameter measurement, but these are generally used in other fields. Their testing method involves placing the workpiece on the instrument and inspecting it individually, which is unsuitable for bearing production lines. Summary of the Invention

[0003] In order to overcome the above-mentioned shortcomings in the prior art, this utility model provides a hole measuring device suitable for flexible bearings.

[0006] Preferably, the pneumatic measuring head is cylindrical, with an internal air passage connecting to the air source, and an airflow nozzle on the side.

[0007] Preferably, the cleaning mechanism includes a cleaning base mounted on a transport track, the upper surface of the cleaning base being hollowed out, a water storage space inside the cleaning base, and a drain pipe connected to the lower end of the water storage space. The drying mechanism includes a drying base mounted on a transport track, the upper surface of the drying base being hollowed out, a water receiving space inside the drying base, and a drain pipe connected to the lower end of the water receiving space.

[0008] Preferably, a lifting mechanism is provided on one side of the transport track. The lifting mechanism is located between the cleaning mechanism and the drying mechanism. The lifting mechanism is equipped with a lifting head. The two ends of the lifting head are respectively provided with a columnar cleaning head and a drying head.

[0012] Figure 2 yes Figure 1 A partial structural diagram.

[0013] Figure 3 This is a schematic diagram of the cleaning head. Detailed Implementation

[0014] The utility model will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] like Figure 1 , 2 As shown in Figure 3, a flexible bearing hole measuring device includes a transport track 4 and a transport mechanism located on one side of the transport track to transport the workpiece from one station to the next. Above the transport track are sequentially arranged a cleaning mechanism, a drying mechanism, and a measuring mechanism. The workpiece needs to be rinsed and dried before measuring the hole diameter to avoid affecting the measurement accuracy.

[0016] The cleaning mechanism includes a cleaning base 9 mounted on a transport track. The upper surface of the cleaning base is hollowed out, and a water storage space is provided inside the cleaning base. The lower end of the water storage space is connected to a drain pipe. The drying mechanism includes a drying base 11 mounted on the transport track. The upper surface of the drying base is hollowed out, and a water receiving space is provided inside the drying base. The lower end of the water receiving space is connected to a drain pipe. A lifting mechanism 6 is provided on one side of the transport track, located between the cleaning mechanism and the drying mechanism. The lifting mechanism has a lifting head 7, and columnar cleaning heads 8 and drying heads 10 are respectively provided at both ends of the lifting head. The cleaning head 8 and the drying head 10 correspond to the cleaning base and the drying base, respectively. Channels are opened inside the cleaning head and the drying head. Several openings connecting the channels are opened on the sides of the cleaning head and the drying head. The cleaning head is connected to a cleaning liquid pump, and the drying head is connected to a fan.

[0017] The cleaning and drying mechanisms are structurally similar, except that the cleaning mechanism connects to the cleaning fluid to rinse the workpiece, while the drying mechanism connects to a fan to dry the workpiece. Both can work simultaneously, therefore the cleaning head and drying head are both connected to the lifting head. The cleaning head 8 sprays rinsing fluid through openings to rinse the workpiece, and the cleaning fluid enters the water storage space through the perforations, then is discharged through the drain pipe. The drying head 10 has openings to dry the workpiece, and any residual cleaning fluid blown off enters the water collection space and is discharged through the drain pipe. To avoid splashing of the cleaning fluid, such as... Figure 3 As shown, the opening 17 is located at the bottom of the head, and the bottom of the washing head and the drying head are provided with an inward stepped spray surface 16. The openings are evenly spaced on the spray surface, and the lower half of the spray surface is rounded.

[0018] In this application, the measuring mechanism mainly adopts a pneumatic measuring instrument. Its core principle is to achieve length measurement through airflow signal conversion. It is suitable for rapid detection of parameters such as inner diameter, outer diameter, thickness, and shape error, and is particularly good at high-precision measurement of deep holes, small holes, and thin-walled parts. In this application, the pneumatic measuring instrument is adapted to be suitable for the detection of flexible bearings. The measuring mechanism includes a measuring side seat 1 located on one side of the transport track. A pneumatic measuring head 3 is slidably mounted on the measuring side seat near the transport track. A semi-open clamping ring 2 is also fixed on the measuring side seat. The clamping ring matches the size of the workpiece. The transport track is open to the position of the pneumatic measuring head, and a lifting base 5 is provided at the opening. A lifting cylinder 15 is fixedly connected to the lower end of the lifting base. The clamping surface 12 of the clamping ring 2 is stepped and matches the upper end and side of the workpiece. The pneumatic measuring head is cylindrical, with an internal air passage connected to the air source, and an airflow nozzle 13 is provided on the side.

[0019] In this application, in addition to the lateral transport of the workpiece by the conveying mechanism, a bottom lifting base is also required to lift the workpiece upwards and confine it within the clamping ring. The clamping surface of the clamping ring 2 is set in a stepped shape, matching the upper end face and side face of the workpiece. That is, the vertical and lateral directions of the workpiece are limited by the clamping ring. The lifting base at the bottom makes reasonable use of the lower space. The workpiece is sent to the lifting base 5 by the conveying mechanism, and the lifting cylinder 15 operates to send the workpiece upwards to the clamping ring. The pneumatic measuring head descends to measure the aperture of the workpiece, and can measure the aperture size at multiple positions in the bearing direction. The pneumatic measuring head is cylindrical with an airflow nozzle on the side, and uses airflow signals to perform non-contact measurement of the workpiece.

[0020] This application has a reasonable structure and can realize non-contact aperture measurement.
