Description

Technical Field

[0001] The utility model relates to the technical field related to transmission shaft detection, in particular to a transmission shaft detection device for heavy-duty industries. Background Art

[0002] The drive shaft is subjected to huge torque and load in heavy-duty industries (such as mining, construction, oil and gas, etc.), so its reliability and performance directly affect the operating efficiency and safety of the entire equipment. Therefore, when the drive shaft is produced, it is necessary to test the outer diameter, dynamic balance and fatigue of the drive shaft. When testing the outer diameter of the drive shaft, a measuring plate and a measuring ruler are generally used for measurement.

[0003] For example, in the Chinese patent application number 202310169922.4, a drive shaft quality inspection device and method are provided. Two hydraulic push rods are started to drive the clamp plate to move downward so that the two measuring plates on the inner side of the clamp plate clamp the drive shaft. Finally, the servo motor is started to drive the slide plate to slide from front to back, so that the measuring plate moves from front to back along the outer side of the drive shaft, so that the slide bar leaves a motion track in the sand trough. By observing the track, it can be determined whether the drive shaft is straight, and by observing the pointer, the outer diameter of the drive shaft can be read.

[0004] However, during the use of this type of detection device, since the transmission shaft is exposed to the air for a long time, an oxide layer will form on the metal surface. The oxide layer will increase the thickness of the transmission shaft surface, thereby causing the measurement result to be biased.

[0005] For this purpose, we propose a transmission shaft detection device for heavy-duty industries. Utility Model Content

[0006] The utility model aims to provide a transmission shaft detection device for heavy-duty industries, so as to solve the problem that the transmission shaft is exposed to the air for a long time, which will cause an oxide layer to form on the metal surface, and the oxide layer will increase the thickness of the transmission shaft surface, thereby causing the measurement result to be larger.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions: a heavy-duty industry transmission shaft detection device comprises a frame, a support frame is symmetrically fixed on the top of the frame, a shaft body slides in the support frame, a base is fixed on the frame, a scraping mechanism for scraping off the oxide layer on the surface of the shaft body is arranged on the base, the scraping mechanism comprises a circular shell sliding on the outer surface of the shaft body, a scraping pad is fixed on the inner wall of the circular shell, the scraping pad is abutted against the shaft body, an auxiliary mechanism for blowing air onto the surface of the shaft body is arranged on the support frame, a U-shaped frame is arranged above the shaft body, a cylinder for driving the U-shaped frame to rise and fall is installed on the top of the frame, a detection plate is arranged on the U-shaped frame, a cylinder for driving the detection plate to move is installed on the U-shaped frame, a scale bar is fixed on the inner wall of the U-shaped frame, a clamping plate is arranged on the support frame, and a cylinder for driving the clamping plate to move is installed on the support frame.

[0008] Furthermore, the scraping mechanism also includes a motor fixed to the inner wall of the base, a turntable is fixed to the output shaft end of the motor, a push head is fixed to the top of the turntable, and an arc-shaped shell is slidably disposed on the outer surface of the push head.

[0009] Furthermore, the scraping mechanism also includes an outer tube fixed to the top of the arc-shaped shell, the inner thread of the outer tube is connected to an inner rod, and the circular shell is fixed to the top of the inner rod.

[0010] Furthermore, the scraping mechanism also includes rectangular bars fixed on two side surfaces of the arc-shaped shell, a fixed cylinder is fixed on the support frame, a sliding rod is fixed to the end of the rectangular bar close to the fixed cylinder, and the sliding rod slides in the fixed cylinder.

[0011] Furthermore, the auxiliary mechanism includes a piston disk fixed to one end of the slide rod located in the fixed cylinder, the piston disk piston moves in the fixed cylinder, and the outer surface of the fixed cylinder is connected to a hose.

[0012] Furthermore, the auxiliary mechanism also includes a connecting shell connected to the outer surface of the circular shell, the other end of the hose is connected to the circular shell, and a blowing hole is opened on the side of the connecting shell close to the shaft body.

[0013] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0014] The utility model can scrape off the oxide layer on the surface of the shaft body before detecting the outer diameter of the shaft body through the setting of the scraping mechanism, so as to avoid the oxide layer increasing the thickness of the shaft body and affecting the detection accuracy. Through the setting of the auxiliary mechanism, the scraping mechanism can simultaneously blow air on the shaft body while scraping the oxide layer. The oxide layer can be blown off by the airflow, thereby improving the removal effect. BRIEF DESCRIPTION OF THE DRAWINGS
