The following embodiments are only used to illustrate the technical solutions of the present application more clearly, so they are only examples and cannot be used to limit the protection scope of the present application. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0030] In view of the problems existing in the prior art in the background art, the embodiments of the present application provide an automatic on-line inner diameter detection tooling for double-row tapered bearings, as Figures 1 to 2 Figure 1 schematically shows a structural diagram of an automatic on-line inner diameter detection tooling for double-row tapered bearings in an embodiment of the present application. The automatic on-line inner diameter detection tooling for double-row tapered bearings includes: a frame 1, a conveyor structure 2 arranged on the tabletop of the frame 1, an inner diameter detection mechanism 3 arranged above the conveyor structure 2, and a control unit 4 connected to the conveyor structure 2 and the inner diameter detection mechanism 3; the conveyor structure 2 includes a conveyor belt 21 and a horizontal clamping mechanism 22 arranged on one side of the conveyor belt 21; the inner diameter detection mechanism 3 includes a first positioning mechanism 31 arranged on the frame 1, a first measurement point 32 arranged on the first positioning mechanism 31, a second positioning mechanism 33 arranged on the conveyor belt 21, a second measurement point 34 arranged on the second positioning mechanism 33, a first swing cylinder 35 connected to the first positioning mechanism 31, and a second swing cylinder connected to the second positioning mechanism 33.

[0031] Specifically, the operation process of the automatic on-line inner diameter detection tooling for double-row tapered bearings in this embodiment is as follows:

[0032] (1) Use the conveyor belt 21 to transfer the double-row tapered roller bearings to be measured to the specified position, and then clamp the double-row tapered roller bearings to be measured through the horizontal clamping mechanism 22 arranged on one side of the conveyor belt 21, and transfer them to the detection position at the center of the conveyor belt 21;

[0033] (2) Control the first positioning mechanism 31 to descend to the inner ring of the double-row tapered roller bearings to be measured through the control unit 4, so that the first measurement point 32 contacts the inner ring surface of the double-row tapered roller bearings to be measured; at the same time, control the second positioning mechanism 33 to rise to the inner ring of the double-row tapered roller bearings to be measured, so that the second measurement point 34 contacts the inner ring surface of the double-row tapered roller bearings to be measured;

[0034] (3) Control the first measurement point 32 and the second measurement point 34 to rotate within the inner ring of the double-row tapered roller bearings to be measured respectively through the first swing cylinder 35 and the second swing cylinder, and measure the inner diameter of the double-row tapered roller bearings to be measured;

[0035] (4) After the measurement is completed, control the first positioning mechanism 31 and the second positioning mechanism 33 to return to the original position through the control unit 4, and then control the horizontal clamping mechanism 22 to clamp the double-row tapered roller bearings to be measured and transfer them to the conveyor belt 21 again;

[0036] (5) The control unit 4 judges whether the inner diameter size is qualified based on the measurement data of the first measurement point 32 and the second measurement point 34, and outputs the detection result.

[0037] Optionally, in order to prevent the double-row tapered roller bearings to be measured from shifting during transportation, limit bars can be set on both sides of the conveyor belt 21.

[0038] To ensure the stability of the frame 1, continue to refer to Figure 1 , in one implementation, support legs 6 are provided at the bottom of the frame 1.

[0039] To ensure that the double-row tapered roller bearings to be measured are transferred to the specified position of the conveyor belt 21, in one implementation, the conveying structure 2 further includes: positioning columns 23 vertically arranged at the groove of the conveyor belt 21.

[0040] Specifically, in this embodiment, the conveyor belt 21 adopts a roller conveyor belt. Furthermore, without affecting the normal operation of the conveyor belt 21, the positioning columns 23 are arranged in the gap between two rollers, achieving the effect of limiting the conveying position of the double-row tapered roller bearings to be measured.

[0041] On the basis of the above embodiments, continue to refer to Figure 2, in one implementation, the first positioning mechanism 31 includes a first inner ring positioning mechanism 311 and an end face positioning mechanism 312 mounted on the upper part of the first inner ring positioning mechanism 311; the end face positioning mechanism 312 includes bearings 313 evenly distributed along the circumference of the first inner ring positioning mechanism 311; the first inner ring positioning mechanism 311 is shaped to match the double-row tapered bearing to be measured, and the first measurement point 32 is provided on the side wall of the first inner ring positioning mechanism 311.

[0042] Specifically, after the double-row tapered bearing to be measured reaches the detection position, lower the first positioning mechanism so that each bearing 313 in the end face positioning mechanism 312 contacts the upper end face of the double-row tapered bearing to be measured, and drive the first inner ring positioning mechanism 311 to descend into the inner ring of the double-row tapered bearing to be measured, so that the first measurement point 32 contacts the inner wall of the double-row tapered bearing to be measured.

[0043] When measuring the inner diameter of the double-row tapered bearing to be measured, the outer rings of the bearings 313 in the end face positioning mechanism 312 contact the upper end face of the double-row tapered bearing to be measured and slide relative to each other, thereby effectively restricting the movement of the double-row tapered bearing to be measured in the axial direction and improving the accuracy and stability of the detection.

[0044] Optionally, the first measurement point 32 can be measured by a contact sensor, or can be measured by a non-contact sensor such as a laser ranging sensor or an ultrasonic sensor.

[0045] Based on the above embodiments, continue to refer to Figure 1 , in one implementation, the first positioning mechanism 31 further includes a first lifting mechanism 314 connecting the frame 1 and the lifting table 5 and a second lifting mechanism 315 connecting the lifting table 5; the first lifting mechanism 314 includes a lead screw 316 and a driving motor; the second lifting mechanism 315 includes a first cylinder 317.

[0046] Specifically, in order to adapt to double-row tapered bearings to be measured with different sizes or installation heights, a height adjustment structure is added to the first positioning mechanism 31 in this embodiment. Among them, the first lifting mechanism 314 is connected between the frame 1 and the lifting table 5, and the lead screw 316 is driven to rotate by the rotational force provided by the driving motor, thereby controlling the lifting height of the lifting table 5 to preliminarily adjust the height of the detection mechanism 3. The second lifting mechanism 315 is installed on the lifting table 5 and uses the first cylinder 317 as the power device to quickly and accurately adjust the vertical positions of the first inner ring positioning mechanism 311 and the end face positioning mechanism 312. Realize fine adjustment of the height of the detection mechanism 3. The driving motor is not shown in the figure.

[0047] Based on the above embodiments, in one implementation, the second positioning mechanism 33 includes a detection table 331 disposed on the conveyor belt 21, a second inner ring positioning mechanism 332 installed at a groove of the detection table 331, and a second air cylinder connected to a lower portion of the second inner ring positioning mechanism 332; the second inner ring positioning mechanism 332 is in a shape matching with the double-row tapered bearing to be measured, and the second measurement point 34 is disposed on a side wall of the second inner ring positioning mechanism 332.

The transverse air cylinder 221 is connected to the slider and controls the movement of the slider in the linear guide through a telescopic rod, thereby driving the horizontal movement of the first manipulator 222 and the second manipulator 223. The movement principle of the longitudinal air cylinder 224 is the same as above. The longitudinal air cylinder is not shown in the figure.

[0051] The operation process includes: after placing the double-row tapered bearing to be measured on the conveyor belt 21, making the double-row tapered bearing to be measured contact with the two positioning columns 23, controlling the longitudinal air cylinder 224 to extend the first manipulator 222 and the second manipulator 223 above the conveyor belt 21, clamping the double-row tapered bearing to be measured into the first manipulator 222 and clamping the bearing that has completed the measurement process into the second manipulator 223, controlling the transverse air cylinder 221 to move the first manipulator 222 and the second manipulator 223 left and right to transport the double-row tapered bearing to be measured to the detection position, and placing the bearing that has completed the measurement process onto the conveyor belt 21, and finally retracting the first manipulator 222 and the second manipulator 223.

[0052] In order to simplify the operation of the double-row tapered bearing inner diameter automatic on-line detection tooling, the relative distance between the first manipulator 222 and the second manipulator 223 on the transverse air cylinder 221 is fixed, and this distance is the length between the positioning column 23 and the detection table 331.

[0053] Based on the previous embodiment, in one implementation, the inner diameter detection mechanism 3 further includes: a first position sensor connected to the first positioning mechanism 31 and a second position sensor connected to the second positioning mechanism 33.

[0054] Specifically, the first position sensor is used to detect whether the first measurement point 32 or the first cylinder 317 has moved to a specific position; the second position sensor is used to detect whether the second measurement point 34 or the second cylinder has moved to a specific position. In this embodiment, the operating conditions of the horizontal clamping mechanism 22 can be designed according to the data of the first position sensor and the second position sensor.

[0055] As an example, the operating conditions include: 1. The operating conditions for the left and right extension and retraction of the first manipulator 222 and the second manipulator 223 are that the first cylinder 317 and the second cylinder are retracted in place;

[0056] 2. The operating conditions for the front and back extension and retraction of the first manipulator 222 and the second manipulator 223 are that the second cylinder is retracted in place;
