Abstract
Description
Technical Field
[0001] This utility model relates to the field of measuring frame assembly technology, specifically a measuring frame assembly mechanism. Background Technology
[0002] The measuring stand is designed to support and secure the object being measured, ensuring its stability during measurement. This stability is crucial for ensuring the accuracy of the measurement results. Using the measuring stand, various dimensions, angles, and shape parameters of objects can be precisely measured, thus meeting the needs for quality control and accurate measurement in industrial production.
[0003] Due to dimensional errors in the machined parts and errors in manual assembly, it is difficult for the measurement center of the measuring mechanism to be located at the position to be measured during use, resulting in large measurement errors and poor measurement results. Therefore, a measuring frame assembly mechanism is proposed to address the above problems. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A measuring frame assembly mechanism of this utility model includes a lower mounting plate. A ball screw sleeve assembly is rotatably connected to the outer side of the lower mounting plate. An upper fixed plate is rotatably connected to the outer side of the ball screw sleeve assembly. A connecting block is fixedly connected to the outer side of the upper fixed plate. A stepper motor is fixedly connected to the outer side of the connecting block. A coupling is fixedly connected to the output end of the stepper motor. The coupling is fixedly connected to the lead screw of the ball screw sleeve assembly. A movable plate is rotatably connected to the outer side of the ball screw sleeve of the ball screw sleeve assembly. A support block is fixedly connected to the outer side of the movable plate. A mounting plate is fixedly connected to the outer side of the support block. A bidirectional adjustable module is fixedly connected to the outer side of the bidirectional adjustable module. A clamping block is fixedly connected to the outer side of the bidirectional adjustable module. A probe is fixedly connected to the inner side of the clamping block. A bearing is provided on the outer side of the probe. A guide post is fixedly connected to the outer side of the lower mounting plate. A sliding... The device is equipped with a linear bearing, which is fixedly connected to the moving plate. The guide post is fixedly connected to the upper fixed plate. This step involves setting up a ball screw sleeve assembly, an upper fixed plate, a connecting block, a stepper motor, a mounting plate, and a probe. In use, the lower mounting plate is first fixed to the machine, and then the bearing is fixed to the lower side of the probe. The stepper motor drives the coupling and the lead screw of the ball screw sleeve assembly to rotate. The lead screw of the ball screw sleeve assembly drives the ball screw sleeve of the ball screw sleeve assembly to move and drive the moving plate to rise and fall. Thus, the moving plate drives the probe to move down and extend into 1 / 3 of the thickness of the bearing inner hole. At this time, the stepper motor stops rotating and a value is read. Then the stepper motor continues to rotate, and when the measuring part of the probe moves down and extends into 2 / 3 of the thickness of the bearing inner hole, another value is read. In this way, the diameter and cylindricity of the bearing inner hole can be measured to determine whether they are qualified. Multiple measurements can be performed to improve the measurement accuracy of the device.
[0006] Preferably, a straight mounting plate is slidably connected to the inner side of the support block, and a guide rail is provided on the outer side of the straight mounting plate. The guide rail and the mounting plate are slidably connected. By setting the straight mounting plate and the guide rail, the straight mounting plate can also be installed on the machine during use. The sliding connection between the straight mounting plate and the support block further restricts the lifting trajectory of the support block. The sliding connection between the guide rail and the mounting plate further restricts the lifting trajectory of the mounting plate, thereby making the lifting of the probe more stable and less prone to shaking, thus improving the stability of the device.
[0007] Preferably, a first adjustment handle and a second adjustment handle are provided on the outer side of the bidirectional adjustable module. This step, by providing the first and second adjustment handles, makes it easier for the user to adjust the bidirectional adjustable module using the first and second adjustment handles, thereby improving the convenience of using the device.
[0008] The advantages of this utility model are:
[0009] 1. This utility model, by setting up a ball screw sleeve assembly, an upper fixing plate, a connecting block, a stepper motor, a mounting plate, and a probe, allows for the following steps: First, the lower mounting plate is fixed to the machine, and then the bearing is fixed to the lower side of the probe. The stepper motor drives the coupling and the lead screw of the ball screw sleeve assembly to rotate. The lead screw of the ball screw sleeve assembly drives the ball screw sleeve of the ball screw sleeve assembly to move, which in turn drives the moving plate to rise and fall. Thus, the moving plate drives the probe to move down and extend into 1 / 3 of the thickness of the bearing's inner hole. At this point, the stepper motor stops rotating, and a value is read. Then, the stepper motor continues to rotate, and when the measuring part of the probe moves down and extends into 2 / 3 of the thickness of the bearing's inner hole, another value is read. In this way, the diameter and cylindricity of the bearing's inner hole can be measured to determine whether they are within acceptable limits. Multiple measurements can be performed to improve the measurement accuracy of the device.
[0010] 2. By setting up a straight mounting plate and a guide rail, this utility model allows the straight mounting plate to be installed on the machine during use. The sliding connection between the straight mounting plate and the support block further restricts the lifting trajectory of the support block. The sliding connection between the guide rail and the mounting plate further restricts the lifting trajectory of the mounting plate, making the lifting of the probe more stable and less prone to shaking, thereby improving the stability of the device.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0019] Specific implementation examples are given below.
[0020] Please see Figure 1-5As shown, a measuring frame assembly mechanism includes a lower mounting plate 1. A ball screw sleeve assembly 2 is rotatably connected to the outer side of the lower mounting plate 1. An upper fixing plate 3 is rotatably connected to the outer side of the ball screw sleeve assembly 2. A connecting block 4 is fixedly connected to the outer side of the upper fixing plate 3. A stepper motor 5 is fixedly connected to the outer side of the connecting block 4. A coupling 6 is fixedly connected to the output end of the stepper motor 5. The coupling 6 is fixedly connected to the lead screw of the ball screw sleeve assembly 2. A movable plate 7 is rotatably connected to the side. A support block 8 is fixedly connected to the outer side of the movable plate 7. A mounting plate 9 is fixedly connected to the outer side of the support block 8. A bidirectional adjustable module 10 is fixedly connected to the outer side of the mounting plate 9. A clamping block 11 is fixedly connected to the outer side of the bidirectional adjustable module 10. A probe 12 is fixedly connected to the inner side of the clamping block 11. A bearing 13 is provided on the outer side of the probe 12. A guide post 14 is fixedly connected to the outer side of the lower mounting plate 1. A linear bearing 15 is slidably connected to the outer side of the guide post 14. The linear bearing 15 and the movable plate 7 are fixedly connected, and the guide post 14 and the upper fixed plate 3 are fixedly connected. This step involves setting up the ball screw sleeve assembly 2, the upper fixed plate 3, the connecting block 4, the stepper motor 5, the mounting plate 9, and the probe 12. In use, the lower mounting plate 1 is first fixed on the machine, and then the bearing 13 is fixed to the lower side of the probe 12. The stepper motor 5 drives the coupling 6 and the screw of the ball screw sleeve assembly 2 to rotate, and the screw of the ball screw sleeve assembly 2 drives the ball screw of the ball screw sleeve assembly 2. The stepper motor 5 stops rotating when the stepper motor 5 moves and drives the moving plate 7 to rise and fall. When the moving plate 7 drives the probe 12 to move down and extend into 1 / 3 of the thickness of the inner hole of the bearing 13, a value is read. Then the stepper motor 5 continues to rotate, and when the measuring part of the probe 12 moves down and extends into 2 / 3 of the thickness of the inner hole of the bearing 13, another value is read. In this way, the diameter and cylindricity of the inner hole of the bearing 13 can be measured to determine whether they are qualified. Multiple measurements can be performed to improve the measurement accuracy of the device.
[0021] Furthermore, such as Figure 1 and Figure 5 As shown, a straight mounting plate 16 is slidably connected to the inner side of the support block 8, and a guide rail 17 is provided on the outer side of the straight mounting plate 16. The guide rail 17 and the mounting plate 9 are slidably connected. By setting the straight mounting plate 16 and the guide rail 17, the straight mounting plate 16 can also be installed on the machine during use. The sliding connection between the straight mounting plate 16 and the support block 8 further restricts the lifting trajectory of the support block 8. The sliding connection between the guide rail 17 and the mounting plate 9 further restricts the lifting trajectory of the mounting plate 9, thereby making the lifting of the probe 12 more stable and less prone to shaking, thus improving the stability of the device.
[0022] Furthermore, such as Figure 2As shown, a first adjustment handle 18 and a second adjustment handle 19 are provided on the outer side of the bidirectional adjustable module 10. By setting the first adjustment handle 18 and the second adjustment handle 19, the user can easily adjust the bidirectional adjustable module 10 using the first adjustment handle 18 and the second adjustment handle 19, thus improving the convenience of using the device.
[0023] Working principle: In use, first fix the lower mounting plate 1 and the straight mounting plate 16 in a suitable position. Then fix the bearing 13 to the lower side of the probe 12. Then start the stepper motor 5, which drives the coupling 6 to rotate. The coupling 6 drives the screw of the ball screw sleeve assembly 2 to rotate. The screw of the ball screw sleeve assembly 2 drives the ball screw sleeve of the ball screw sleeve assembly 2 to move. The ball screw sleeve of the ball screw sleeve assembly 2 drives the moving plate 7 to move. The moving plate 7 drives the support block 8 to move. The support block 8 drives the mounting plate 12 to move. The plate 9 moves, which in turn moves the bidirectional adjustable module 10. The bidirectional adjustable module 10 then moves the clamping block 11, which in turn moves the probe 12. When the probe 12 moves down and extends to 1 / 3 of the thickness of the inner hole of the bearing 13, the stepper motor 5 stops rotating and a value is read. Then the stepper motor 5 continues to rotate, and when the measuring part of the probe 12 moves down and extends to 2 / 3 of the thickness of the inner hole of the bearing 13, another value is read. This allows us to measure whether the diameter and cylindricity of the inner hole of the bearing 13 are up to standard.
