Description

Technical Field

[0001] This utility model relates to the field of bearing manufacturing technology, and in particular to a device for measuring the outer ring height of a bearing used in a universal joint. Background Technology

[0002] For bearings used in universal joints, the assembly process in their manufacturing requires the height of the formed bearing outer ring as a reference. There are two heights here: one is the total height of the outer ring, and the other is the step height of the open end of the outer ring. Therefore, before entering the next process, these two heights of the bearing outer ring should be accurately measured to reject outer rings that do not meet the height requirements.

[0003] In the current production process, the measurement of these two heights of the bearing outer ring is basically done manually by inspectors using micrometers. Each height is measured separately, which is not only inefficient and difficult to guarantee in terms of measurement accuracy, but also requires a lot of work. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the prior art, this utility model provides a bearing outer ring height measuring device for universal joints that can effectively ensure measurement accuracy and improve work efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a bearing outer ring height measuring device for universal joints, including a testing platform. The testing platform is provided with a right-angle channel for the outer ring of the bearing to be tested to move. A testing area is provided in the horizontal section of the right-angle channel. A lifting plate is provided above the testing area. A first dial indicator for measuring the total height of the bearing outer ring and a second dial indicator for measuring the step height of the open end of the bearing outer ring are installed on the lifting plate. A push plate is provided on the outer side of the vertical section of the right-angle channel to push the bearing outer ring to be tested to the testing area. A rotating wheel is provided on the rear side of the testing area. When measuring, the rotating wheel moves forward and rubs against the outer circumferential surface of the bearing outer ring to drive the bearing outer ring to rotate. When the measurement is completed, it moves backward and moves away from the outer circumferential surface of the bearing outer ring. A limiting post is provided on the front side of the testing area to contact the outer circumferential surface of the bearing outer ring during testing.

[0006] Specifically, a fixed plate is provided above the lifting plate, and three triangularly distributed sliding columns are fixedly connected between the fixed plate and the testing platform. The lifting plate slides in conjunction with the sliding columns, and a lifting cylinder with a piston rod fixedly connected to the lifting plate is installed on the fixed plate.

[0007] Furthermore, notches are provided on both the front and rear sides of the horizontal section of the right-angle material channel, and limit posts are fixed at the left and right ends of the notch on the front side of the horizontal section of the right-angle material channel, and the rotating wheel is located at the notch on the rear side of the horizontal section of the right-angle material channel.

[0008] Furthermore, the bottom surface of the testing platform is fixed with two slide rails distributed on the left and right. A motor base is slidably mounted on the slide rails. A motor that drives the rotating wheel is mounted on the motor base. A vertical plate with the same width as the motor base is fixed on the bottom surface of the testing platform in front of the motor base. Tension springs that pull the motor base to move during testing are respectively connected between the two sides of the vertical plate and the two sides of the motor base. A push cylinder that pushes the motor base backward after testing is completed is installed on the vertical plate.

[0009] Furthermore, a pusher cylinder is installed on the detection platform outside the vertical section of the right-angle material channel. The piston rod of the pusher cylinder is connected to a pusher plate, which pushes the pusher plate through the vertical section of the right-angle material channel to move the outer ring of the bearing to the detection area.

[0010] Preferably, the push plate end face has an arc-shaped surface that matches the outer peripheral surface of the bearing outer ring.

[0011] The beneficial effects of this utility model are: by using a lifting plate to drive the first and second dial indicators to rise and fall synchronously, and by using the friction of the rotating wheel to drive the outer ring of the bearing to rotate, the total height of the outer ring of the bearing and the step height located in the detection area are measured, which effectively ensures the measurement accuracy and improves the measurement efficiency.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0019] like Figures 1-4 The device shown is a bearing outer ring height measuring device for universal joints, including a rectangular testing platform 1. The testing platform is provided with a right-angle channel 2 formed by baffles. The right-angle channel 2 includes a vertical section and a horizontal section. The vertical section is located on the side of the testing platform 1, and the horizontal section is located on the rear side of the testing platform 1. The bearing outer ring 10 to be tested moves from the opening of the vertical section into the right-angle channel 2.

[0020] A detection area 3 is provided at the right end of the horizontal section of the right-angle material channel 2 where it connects with the vertical section. A push plate 7 is provided outside the right side baffle of the vertical section of the right-angle material channel 2. The end of the push plate 7 is an arc-shaped surface that matches the outer circumferential surface of the bearing outer ring 10, so as to better push the bearing outer ring 10 to move towards the detection area 3. A rectangular hole with clearance fit to the push plate is provided on the right side baffle of the vertical section of the right-angle material channel 2. A cylinder plate is fixed on the right end face of the detection table 1. A push cylinder 20 is installed on the cylinder plate. The piston rod of the push cylinder 20 is fixed to the right end of the push plate 7. The push cylinder 20 pushes the push plate 7 through the rectangular hole on the right side baffle of the vertical section of the right-angle material channel 2, thereby pushing the bearing outer ring 10 to the detection area 3.

[0021] A lifting plate 4 is provided above the detection area 3, and a fixed plate 11 is provided above the lifting plate 4. Three triangularly distributed sliding columns 12 are fixed between the fixed plate 11 and the detection table 1. The lifting plate 4 and the sliding columns 12 are slidably engaged. A lifting cylinder 13 with a piston rod fixed to the lifting plate 4 is installed on the fixed plate 11.

[0022] Two dial indicators are installed on the lifting plate 4. One is a first dial indicator 5 for measuring the total height of the outer ring 10 of the bearing, and the other is a second dial indicator 6 for measuring the height of the step at the open end of the outer ring 10 of the bearing. The measuring pointers of the first dial indicator 5 and the second dial indicator 6 both pass through the lifting plate 4 and point to the detection area 3.

[0023] The right-angle material channel 2 has notches on both the front and rear sides of the horizontal section, which correspond to the position of the detection area 3. Limiting posts 9 are fixed at the left and right ends of the notch on the front side of the horizontal section of the right-angle material channel 2, and a rotating wheel 8 is provided at the notch on the rear side of the horizontal section of the right-angle material channel 2.

[0024] The bottom surface of the testing platform 1 is fixed with two slide rails 14 distributed on the left and right. A motor base 15 is slidably mounted on the slide rails 14. A motor 16 that drives the rotating wheel 8 to rotate is mounted on the motor base 15. A vertical plate 17 with the same width as the motor base 15 is fixed on the bottom surface of the testing platform 1 in front of the motor base 15. Tension springs 18 that pull the motor base 15 to move during testing are respectively connected between the two sides of the vertical plate 17 and the two sides of the motor base 15. A push cylinder 19 that pushes the motor base 15 to move backward after testing is completed is mounted on the vertical plate 17.

[0025] During measurement, the outer ring 10 of the bearing enters along the vertical section of the right-angle material channel 2. At this time, the push cylinder 19 pushes the motor base 15 backward, causing the rotating wheel 8 to move away from the detection area 3. When the outer ring 10 of the bearing moves to the connection between the vertical and horizontal sections of the right-angle material channel 2, the push cylinder 20 is activated, pushing the push plate 7 through the rectangular hole on the right side baffle of the vertical section of the right-angle material channel 2, pushing the outer ring 10 of the bearing to the detection area 3. Then, the push cylinder 19 is depressurized, and under the action of the tension spring 18, the motor base 15 moves forward, causing the rotating wheel 8 to fit against the outer ring 10 of the bearing. On the outer circumferential surface of the rear side of bearing outer ring 10, and simultaneously on the outer circumferential surface of the front side of bearing outer ring 10, contact the limiting post 9. The starting motor 16 drives the rotating wheel 8 to rotate, and the rotating wheel 8, through friction, drives the bearing outer ring 10 to rotate. The lifting cylinder 13 actuates, pushing the lifting plate 4 downwards along the sliding column 12. The lifting plate 4 drives the first dial indicator 5 and the second dial indicator 6 to move downwards simultaneously. The pointer of the first dial indicator 5 completes the measurement of the total height of the bearing outer ring 10, and the pointer of the second dial indicator 6 completes the measurement of the step height at the open end of the bearing outer ring 10. After measurement, the lifting cylinder 13 drives the lifting plate 4 upwards, and the first dial indicator 5 and the second dial indicator 6 rise and reset simultaneously. Then, the push cylinder 19 actuates again to push the rotating wheel 8 out of the detection area 3, waiting for subsequent bearing outer rings 10 to enter the detection area 3. This process is repeated to complete the measurement of the total height and step height of all bearing outer rings 10.

[0026] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
