Description

Technical Field

[0001] This utility model relates to the field of mechanical bearing size measurement technology, and in particular to a mechanical bearing size measurement device. Background Technology

[0002] In the field of mechanical manufacturing, mechanical bearings are key basic components. Their dimensional accuracy directly affects the operational stability, service life and overall performance of equipment. Therefore, the rapid and accurate measurement of parameters such as the inner and outer diameters and width of bearings has always been an important requirement in the production and quality inspection process. With the development of automated testing technology, some semi-automatic or fully automatic measuring equipment has appeared on the market. However, most of them still have insufficient adaptability. For example, the clamps mostly use rigid contact, which cannot be compatible with the quick replacement of bearings of different specifications. During the clamping process, there is a lack of real-time monitoring of the contact force, which may still cause bearing damage due to loss of force control. Therefore, traditional measurement methods are no longer sufficient to meet the comprehensive needs of efficient measurement. There is an urgent need for a mechanical bearing size measurement device to address the shortcomings of existing technologies and adapt to the quality inspection requirements of large-scale production of precision bearings. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mechanical bearing dimension measuring device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A mechanical bearing dimension measuring device includes a mounting base. A mechanical bearing body is placed on a placement seat fixed to the top outer wall of the mounting base. A slide body is fixed to the top outer wall of the mounting base. Two sets of sliders are movably connected to the inner wall of the slide body. A clamping plate component installed on the top outer wall of the slider includes a mounting plate, a clamping plate, and a pressure sensor. The mounting plate is fixed to the top outer wall of the slider. The pressure sensor is fixed between the mounting plate and the clamping plate. A mounting shell is fixed to the clamping plate. A ball is movably connected inside the mounting shell.

[0005] As a further embodiment of this utility model: a bidirectional threaded rod is movably connected between the inner walls on both sides of the slide body, and a servo motor is fixed on one outer wall of the slide body. The output end of the servo motor and one end of the bidirectional threaded rod are connected by a coupling.

[0006] As a further improvement of this utility model: the bidirectional threaded rod and the side of the slider are threaded together.

[0007] As a further improvement of this utility model, a controller is installed on the top outer wall of the mounting base.

[0008] As a further improvement of this invention, the controller, pressure sensor, and servo motor are electrically connected.

[0009] As a further embodiment of this utility model: the measuring components installed on the outer walls of both sides of the placement seat include measuring plates and T-shaped rods. The T-shaped rods are fixed to the side walls of the placement seat, and the measuring plates are movably connected to the outer walls of the T-shaped rods. A scale is fixed on one side of the outer wall of one of the measuring plates, and a digital display mechanism is installed on the other measuring plate.

[0010] As a further improvement of this invention, the scale and another measuring plate are movably connected.

[0011] As a further embodiment of this utility model: a spring is sleeved on the outer wall of the T-shaped rod, and the two ends of the spring are respectively fixed to the outer wall of one side of the measuring plate and the inner wall of one side of the T-shaped rod.

[0012] Compared with the prior art, the present invention provides a mechanical bearing dimension measuring device, which has the following advantages: 1. The clamping force between the ball and the mechanical bearing body is monitored in real time by a pressure sensor, and the rotation of the bidirectional threaded rod is controlled by the controller in conjunction with the servo motor to ensure that the clamping force is always within the safe threshold and to avoid damage to the bearing surface due to excessive clamping.

[0013] 2. The spring of the measuring component pushes the measuring plate to automatically fit against the side of the bearing body. Combined with the scale and the digital display mechanism based on the principle of capacitive or optical grating, the mechanical displacement can be directly converted into a high-precision digital reading. At the same time, the bearing body rotates around the rolling ball, which is convenient for measuring the diameter at different positions of the circumference, improving the comprehensiveness and accuracy of the measurement.

[0014] 3. The servo motor drives the bidirectional threaded rod to achieve automatic synchronous clamping of the clamping plate, and the movable connection of the ball bearing allows the bearing to rotate and slide smoothly, reducing manual adjustment steps.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] A mechanical bearing dimension measuring device, such as Figures 1 to 4 As shown, the device includes a mounting base 1, a placement seat 6 fixed to the top outer wall of the mounting base 1 by screws, a mechanical bearing body 3 for dimensional measurement placed on the placement seat 6, a slide body 7 fixed to the top outer wall of the mounting base 1 by screws, a bidirectional threaded rod 4 rotatably connected between the inner walls of the two sides of the slide body 7, a servo motor 9 fixed to one side outer wall of the slide body 7 by screws, the output end of the servo motor 9 and one end of the bidirectional threaded rod 4 connected by a coupling, two sets of sliders 17 slidably connected to the inner wall of the slide body 7, the bidirectional threaded rod 4 and the sides of the sliders 17 being threadedly connected, a clamping plate is installed on the top outer wall of the sliders 17, a mounting shell 14 is fixed to the clamping plate by screws, and a ball bearing 16 is movably connected inside the mounting shell 14. When measuring the dimensions of the mechanical bearing body 3, the mechanical bearing body 3 is first placed on top of the placement seat 6. The servo motor 9 drives the bidirectional threaded rod 4 to rotate. The bidirectional threaded rod 4 is provided with positive and negative threads. When the bidirectional threaded rod 4 rotates, the two sliders 17 can move relative to each other under the guidance of the slide body 7, so that the distance between the two clamping plates gradually decreases. When the ball 16 movably connected in the mounting shell 14 installed on the clamping plate moves to fit against the outer circumference of the mechanical bearing body 3, it laterally limits the mechanical bearing body 3. At the same time, due to the movable connection between the ball 16 and the mounting shell 14, the mechanical bearing body 3 can rotate along the outer spherical wall of the ball 16 while being laterally limited, and can also slide up and down along the outer spherical wall of the ball 16. In this embodiment, the number of mounting shells 14 and balls 16 installed on each clamping plate is preferably two sets.

[0020] The clamping plate includes a mounting plate 2, a clamping plate 15, and a pressure sensor 18. The mounting plate 2 is fixed to the top outer wall of the slider 17 by screws, and the pressure sensor 18 is fixed to one side outer wall of the mounting plate 2 by screws. The clamping plate 15 and the pressure sensor 18 are fixedly connected by screws. When the mechanical bearing body 3 is laterally limited, after the outer wall of the ball 16 and the outer circumferential wall of the mechanical bearing body 3 come into contact, the pressure sensor 18 is used to monitor the clamping force between the ball 16 and the mechanical bearing body 3 to ensure the safety of the mechanical bearing body 3 during the clamping process and to avoid damage caused by excessive clamping force.

[0021] A controller 8 is installed on the top outer wall of the mounting base 1; The controller 8 receives the clamping force signal between the ball 16 and the mechanical bearing body 3 fed back by the pressure sensor 18 through an electrical connection, and controls the servo motor 9 to drive the bidirectional threaded rod 4 to rotate, so that the two sliders 17 drive the clamping plate to move relative to each other until the clamping force reaches the safety threshold to complete the lateral limit.

[0022] Measuring components are installed on the outer walls of both sides of the placement base 6. The measuring components include measuring plates 5 and T-shaped rods 13. The T-shaped rods 13 are fixed to the side walls of the placement base 6 by screws. The measuring plates 5 are slidably connected to the outer walls of the T-shaped rods 13. A spring 12 is sleeved on the outer wall of the T-shaped rods 13. The two ends of the spring 12 are respectively fixed to the outer wall of one side of the measuring plate 5 and the inner wall of one side of the T-shaped rod 13. A scale 11 is fixed to the outer wall of one side of the measuring plate 5, and the scale 11 is slidably connected to the other measuring plate 5. A digital display mechanism 10 is installed on the other measuring plate 5. When the mechanical bearing body 3 is laterally limited, the elastic force of the spring 12 makes the sides of the two sets of measuring plates 5 and the sides of the mechanical bearing body 3 fit together. At the same time, the straight line where the contact point between the two measuring plates 5 and the sides of the mechanical bearing body 3 is located passes through the axis of the mechanical bearing body 3. Then, the length of the scale 11 between the two measuring plates 5 is the diameter of the mechanical bearing body 3. The diameter of the mechanical bearing body 3 can be displayed by the digital display mechanism 10. The digital display mechanism 10 is based on capacitive grating measurement technology or grating encoding principle. Through the relative displacement between the scale 11 and the movable probe, it drives the internal sensor, such as the capacitive grating or grating, to generate periodically changing electrical signals. After being processed by electronic circuits, these signals are converted into digital signals and displayed in real time, realizing high-precision digital reading of the measured dimension. Its core is to convert the mechanical displacement into electrical signals for digital processing. Its specific structure can be referenced from digital display vernier calipers. Meanwhile, to ensure the accuracy of the measurement, the operator can rotate the mechanical bearing body 3 relative to the ball 16 during the measurement process to adjust the contact position between the measuring plate 5 and the side of the mechanical bearing body 3, thereby measuring the diameter at different positions on the outer circumference of the mechanical bearing body 3.

[0023] Working principle: First, the mechanical bearing body 3 is placed on the placement seat 6. Then, the controller 8 starts the servo motor 9 to drive the bidirectional threaded rod 4 to rotate, which drives the two sliders 17 to move relative to each other along the slide body 7. This causes the mounting shell 14 and the ball 16 on the clamping plate to gradually approach and fit against the outer circumference of the bearing body 3. The pressure sensor 18 monitors the clamping force in real time and the controller 8 controls the start and stop of the motor 9 to ensure clamping safety. After the lateral limit is completed, the spring 12 in the measuring component pushes the two measuring plates 5 to fit against the side of the bearing body 3. The digital display mechanism 10 converts the distance between the two measuring plates 5 into a digital signal to display the diameter size.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
