Embodiment Construction

[0035] The present invention will be further described below in conjunction with accompanying drawing.

[0036] like figure 1 As shown, an online measuring machine for bearing assembly clearance includes a top plate 1, a body 8, a worktable lifting and rotating mechanism, a clamping workbench, a constant pressure measuring mechanism and a controller. The workbench lifting and rotating mechanism includes a lifting guide column 17, a lifting platform 18, a lifting drive assembly, a rotating drive assembly 16 and a lifting frame 21. Lifting frame 21 is fixed on the fuselage 8 . The four corners of lifting platform 18 are all fixed with vertically arranged lifting guide posts 17 . Four guide sleeves fixed on the fuselage 8 and four lifting guide posts 17 constitute sliding pairs respectively. The lifting drive assembly includes a lifting nut, a lifting screw mandrel 19 and a lifting motor 20 . The vertically arranged lifting screw mandrel 19 is supported on the lifting frame 2...

Abstract

The invention discloses a bearing assembly clearance on-line measuring machine and a clearance measuring method thereof. When the inner and outer rings of the bearing are assembled, the clearance canbe inconsistent or even exceed the tolerance range. The bearing assembly clearance on-line measuring machine disclosed by the invention comprises a machine body, a worktable lifting and rotating mechanism, a clamping worktable and a constant pressure measuring mechanism. The clamping worktable includes a V-shaped positioning clamping block, a clamping driving assembly, and a worktable. The constant pressure measuring mechanism includes a pressure detector, a traverse driving mechanism, a mounting block, a guide rail, a measuring slider, a scale grating, and a grating reading head. The pressuredetector includes a measuring rod seat, a pressure sensor, and a measuring rod. Two pressure sensors are arranged in a pressure detecting groove of the mounting block at intervals. The measuring rodpasses through the measuring rod seat and the top end is located between the two pressure sensors. According to the invention, by designing the constant pressure measuring mechanism and a workpiece positioning and clamping device, the online measurement problem of the clearance in the automatic assembly line of the rolling bearing can be solved.

Description

technical field [0001] The invention belongs to the technical field of intelligent manufacturing, and in particular relates to an automatic device for on-line measurement of rolling bearing assembly clearance and a clearance measurement method thereof. The measured data is used as an important index for evaluating the assembly quality of rolling bearings. Background technique [0002] Bearings are important mechanical basic components, and their performance and quality determine the performance and quality of machinery and equipment to a certain extent. my country is the largest manufacturer and consumer of various types of bearings, but there is a big gap compared with foreign technology and quality levels. At present, in the bearing manufacturing process, turning and grinding automatic lines have been widely used. The automatic assembly line is mostly completed manually due to many processes and complicated actions. Because the quality of bearing assembly has a great inf...
