Example 1

Referring to fig. 1-5, the present embodiment provides a device for measuring height difference between an inner ring and an outer ring of a tapered roller bearing, including a workbench 10, fixing rods 111 are disposed on both sides of the workbench 10, a connecting rod 122 is disposed on a surface of each fixing rod 111, a first connecting block 20 is disposed at a bottom of each connecting rod 122, a first chute 211 is disposed on an inner wall of each first connecting block 20, a hydraulic rod 222 is disposed inside each first chute 211, a piston head of each hydraulic rod 222 is connected to a second connecting block 233, a rotating disk 30 is disposed at a bottom of each second connecting block 233, a second chute 311 is disposed at a bottom of each rotating disk 30, third connecting blocks 322 are disposed on both sides of the bottom of each rotating disk 30, the two third connecting blocks 322 are slidably connected to the second chute 311, third chutes 333 are disposed on inner walls of the two third connecting blocks 322, detecting rods 344 are disposed at bottoms of the two third connecting blocks 322, the two detecting rods 344 are slidably connected to the two third chutes 333, and it is convenient to detect the inner ring and the outer ring of the bearing.

The working principle is as follows: when the height difference between the inner ring and the outer ring of the bearing is detected by a user, firstly, the user places the bearing to be detected on the workbench 10, moves the bearing to the bottom of the first connecting block 20, when the bearing is positioned at the bottom of the first connecting block 20, the hydraulic rod 222 is started, the hydraulic rod 222 extends out of the piston rod, the piston rod can enable the second connecting block 233 to move downwards, the user can enable the third connecting block 322 to move in the second chute 311 according to the size of the bearing to be measured, after the third connecting block 322 moves to a specified position, the user slides the detection rod 344 to the bottom of the third chute 333, when the piston rod enables the second connecting block 233 to move downwards, the detection rod 344 firstly contacts the bearing, is acted by force, the detection rod 344 is pushed back into the third chute 333, and the height difference between the inner ring and the outer ring of the bearing can be known according to the sliding positions of the two detection rods 344 in the chutes of the two third chutes 333.

Because this device is when measuring the bearing, the sharp-pointed part of measuring rod 344 touches the bearing, can make the surface of bearing receive wearing and tearing, consequently, measuring rod 344 bottom is equipped with the rubber sleeve, when using this device to measure the bearing, the rubber sleeve can avoid measuring rod 344 direct contact bearing, avoids appearing measuring rod 344 and produces the mar with the surface of bearing.

Considering that when the bearing is measured, a user needs to adjust the angle of the motor 244 to conveniently measure the bearing, therefore, the motor 244 is arranged inside the second connecting block 233, the output shaft of the motor 244 is coaxially connected with the rotating shaft of the rotating disc 30, when the user needs to adjust the angle of the detection rod 344, the motor 244 is powered on, after the motor 244 is powered on, the output shaft of the motor 244 rotates, when the output shaft of the motor 244 rotates, the rotating disc 30 rotates to adjust the angle of the detection rod 344, and when the angle of the detection rod 344 is adjusted to a certain position, the user can conveniently measure the bearing.

In the service environment of difference, need highly adjust this device when the user, the convenience is measured the interior outer lane of bearing, therefore, workstation 10 bottom four corners department all is equipped with supporting leg 50, supporting leg 50 is inside to have seted up fifth spout 511, supporting leg 50 bottom is equipped with bracing piece 522, bracing piece 522 and fifth spout 511 sliding connection, when the user needs to adjust this device highly in the service environment of difference, follow the inside roll-off of fifth spout 511 with bracing piece 522, slide when bracing piece 522 and can drive the highly adjusting of this device, reach a certain position when bracing piece 522 and can the person of facilitating the use measure the bearing.

Considering that under different service environments, the user needs to move the device beside the bearing bin, therefore, the bottom of the supporting rod 522 is provided with the universal wheel 533, when the user needs to move the device, the user pushes the device, the universal wheel 533 can rotate, and when the universal wheel 533 rotates, the user can be assisted to move the device.

Because when measuring the bearing, the bearing probably leads to the skew because of the effect of extrusion force, thereby make and detect the error, consequently, fourth spout 40 has been seted up at workstation 10 top, the fourth spout 40 left and right sides all is equipped with fixed block 411, fixed block 411 and fourth spout 40 sliding connection, fixed block 411 top structure is semi-circular, through setting up fixed block 411 top into semi-circular, and most bearings are circular, the user removes fixed block 411 according to the size of bearing, move the assigned position when fixed block 411, fixed block 411 can carry out the centre gripping to the bearing, avoid bearing skew in the measurement, the error appears.

When the device for measuring the height difference of the inner ring and the outer ring of the tapered roller bearing in the embodiment is used specifically, the working principle is as follows: when the height difference between the inner ring and the outer ring of the bearing of the user is detected, firstly, the user places the bearing to be detected on the workbench 10, moves the bearing to the bottom of the first connecting block 20, when the bearing is positioned at the bottom of the first connecting block 20, the hydraulic rod 222 is started, the hydraulic rod 222 extends out of the piston rod, the piston rod can enable the second connecting block 233 to move downwards, the user enables the third connecting block 322 to move in the second sliding groove 311 according to the size of the bearing to be measured, after the third connecting block 322 moves to a specified position, the user slides the detecting rod 344 to the bottom of the third sliding groove 333, when the piston rod enables the second connecting block 233 to move downwards, when the user needs to adjust the angle of the detecting rod 344, the motor 244 is powered on, after the motor 244 is powered on, the output shaft of the motor 244 rotates, the rotating disc 30 rotates, the angle of the detecting rod 344 is adjusted, when the piston rod pushes the second connecting block 233, the detecting rod 344 contacts the bearing and is acted by a force, the detecting rod 344 is pushed back into the third sliding groove, and the height difference between the inner ring and the inner ring 333 is known according to the height difference between the two sliding grooves 333.

The foregoing shows and describes the basic principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only the preferred embodiments of the present invention, and is not intended to limit the present invention, and that there may be various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall within the scope of the present invention as claimed.
