Description

Technical Field

[0001] This utility model relates to the field of mechanical testing technology, and in particular to an integrated parallelism and roundness testing machine. Background Technology

[0002] In modern industrial production, the accurate detection of parameters related to cylinders is crucial. Especially in fields such as precision machinery manufacturing and high-end equipment manufacturing, parameters such as the parallelism of cylindrical parts directly affect the performance and quality of the entire equipment. A device that can efficiently and accurately detect the parallelism of cylinders plays an indispensable role in improving production efficiency and ensuring product quality. This is the important technological background of the integrated parallelism and roundness testing machine.

[0003] Currently, in the field of parallelism and roundness testing, the common approach is to use relatively simple manual auxiliary testing devices. For example, by manually using some basic measuring tools, such as calipers and rulers, multiple measurements are taken on the cylinder, and then the parallelism is estimated based on the measurement data. This method mainly relies on manual operation, and the technical principle is based on simple geometric measurement concepts. Data is observed and recorded manually, and then simple calculations and analyses are performed. However, because it is difficult to keep the position and force of each measurement completely consistent during manual operation, the deviation of the measurement data is relatively large.

[0004] However, this existing detection method has problems such as complex operation, low detection accuracy, and unstable data. Manual operation not only consumes a lot of time and energy, but also the differences in the techniques and habits of different operators can cause large fluctuations in the results of each test, making it impossible to guarantee the consistency of detection accuracy and the stability of data, and making it difficult to meet the needs of modern industrial production for high-precision detection.

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 protection scope of the present utility model.

[0018] Reference Figure 1 - Figure 7 The present invention provides an embodiment of a parallelism and roundness integrated testing machine, including a control base 1, which is the control center of the whole machine and starts the entire testing process. A fixing component is provided on the top of the control base 1, a driving component is provided on the top of the control base 1, and a pressure component is provided on the top of the control base 1. The fixing assembly includes a spring pin 15, which is positioned above the control base 1. One end of the spring pin 15 is attached to the product 18. The spring pin 15 is mounted on the support plate 7 and moves with the support plate 7 to hold the product 18 in place and assist the dial indicator 13 in detection. A spring pin movable block 17 is fixedly connected to the outer wall of the spring pin 15. The spring pin movable block 17 connects the dial indicator 13 to the support plate 7, allowing the dial indicator 13 to better fit the surface of the product 18 for detection. A limit ring 14 is fixedly connected to the outer wall of the spring pin movable block 17. The limit ring 14 is fixed to the spring pin movable block 17 by bolts 16, limiting its range of motion and ensuring the stability of the dial indicator 13's detection position. Bolts 16 are fixedly connected to the inner wall of the limit ring 14, effectively fixing the spring pin movable block 17. The support plate 7 is fixedly connected to the outer wall of the bolts 16, and the support plate 7 is connected to the connecting fork block 9. The connecting fork block 9 moves and slides on the guide post 6, carrying the spring pin 15 and the dial indicator 13. The inner wall of the support plate 7 is fixedly connected to the connecting post 10, and the outer wall of the connecting post 10 is fixedly connected to the connecting fork block 9. The inner wall of the spring pin movable block 17 is fixedly connected to the dial indicator 13, which detects the product 18. The dial indicator 13 is fixed to the support plate 7 by the spring pin movable block 17 and obtains the detection data of the product 18. A fixed upper seat 5 is set above the dial indicator 13, and a cylinder 8 is fixedly connected to the upper surface of the fixed upper seat 5. The cylinder 8 outputs thrust to push the connecting fork block 9, providing power for detecting the tooth surface diameter of the product 18. The output section of the cylinder 8 is fixedly connected to the outer wall of the connecting fork block 9. The outer wall of the support plate 7 is slidably connected to the guide post 6, which provides guidance for the sliding of the support plate 7 and ensures the straightness of the movement of the support plate 7. A limit block 12 is fixedly connected to the outer wall of the guide post 6, and a fixed base 4 is fixedly connected to the outer wall of the guide post 6.

[0019] Specifically, the start control unit 1, acting as the central control unit of the entire machine, initiates the entire testing process. The fixed components begin to operate, cylinder 8 starts, and outputs thrust to push the connecting fork block 9. The connecting fork block 9 drives the support plate 7 to slide on the guide post 6. The guide post 6 ensures the straightness of the support plate 7's movement, while the limit block 12 limits its stroke. During the movement of the support plate 7, the spring pin 15 installed on the support plate 7 moves accordingly and abuts against the product 18, achieving product 18 positioning and assisting the dial indicator 13 in detection. The spring pin 15 connects the dial indicator 13 to the support plate 7 through the spring pin movable block 17, allowing the dial indicator 13 to better fit the surface of the product 18. The limit ring 14 cooperates with the bolt 16 to further fix the spring pin movable block 17, ensuring the stability of the dial indicator 13's detection position, thereby accurately obtaining the product 18's detection data. This solves the problems of complex operation, low detection accuracy, and unstable data in the existing technology, achieving the effect of improving the automation level of detection and convenient operation. Through the close cooperation of various components, the detection efficiency and accuracy are improved.

[0020] Reference Figure 1 - Figure 7The drive assembly includes a roller 19, which is positioned above the control base 1. A rotating support roller 20 is fixedly connected to the inner wall of the roller 19. The rotating support roller 20 connects a synchronous pulley 28 and a linear bearing 27 to the roller 19, transmitting rotational power. The linear bearing 27 is fixedly connected to the outer wall of the rotating support roller 20 and is mounted on the rotating support roller 20, rotating with it to provide stable support and guidance for the roller 19, ensuring smooth rotation. A fixed platform 11 is rotatably connected to the outer wall of the rotating support roller 20. The fixed platform 11 is used to place the product 18 to be tested and provides stable support for the device. A track 29 is located below the fixed platform 11. The synchronous pulley 28 is fixedly connected to the outer wall of the rotating support roller 20, and the synchronous pulley 28 is driven by the track 29. The product 18 rotates downwards, and the linear bearing 27 and roller 19 rotate synchronously through the rotating support roller 20. A motor 31 is fixedly connected to the upper surface of the fixed platform 11. The motor 31 provides power to the synchronous pulley 30, driving the product 18 to rotate and detect its outer diameter. The output end of the motor 31 is fixedly connected to the synchronous pulley 30. The synchronous pulley 30 receives power from the motor 31 and rotates to drive the track 29, transmitting power to the synchronous pulley 28. Both the synchronous pulley 28 and the synchronous pulley 30 are engaged with the track 29. The track 29 connects the synchronous pulley 30 and the synchronous pulley 28, relying on friction to drive the synchronous pulley 28 to rotate, thus achieving power transmission. A dial indicator 21 is installed above the fixed platform 11. The dial indicator 21 is fixed to the product 18 through the fixing module 22. When product 18 rotates, its outer diameter is detected, and the data is transmitted to display 2. A fixing module 22 is fixedly connected to the outer wall of dial indicator 21, which fixes dial indicator 21 to ensure good contact between dial indicator 21 and product 18 when product 18 rotates, ensuring accurate outer diameter detection. The pressure assembly includes a sliding module 32, which is set above control base 1. A fixing bracket 3 is slidably connected to the inner wall of sliding module 32. The fixing bracket 3 has a groove inside for sliding module 32 to slide, and also fixes cylinder 26 to ensure stable operation of cylinder 26 and smooth sliding of sliding module 32. Cylinder 26 is fixedly connected to the outer wall of fixing bracket 3. Cylinder 26 and cylinder 8 start simultaneously, and their thrust pushes sliding module 32 to slide on fixing bracket 3. To achieve the fixing operation of product 18, the output end of cylinder 26 is fixedly connected to the outer wall of sliding module 32. Sliding module 32 slides along the slide groove of fixed bracket 3 under the push of cylinder 26, causing the moving pressure block 25 and shock-absorbing module 33 to move. The shock-absorbing module 33 is slidably connected to the outer wall of sliding module 32. The shock-absorbing module 33 and moving pressure block 25 are connected by a shock-absorbing spring 34, which buffers the pressure when moving pressure block 25 fixes product 18, protecting product 18. One end of shock-absorbing spring 34 is fixedly connected to the inner wall of shock-absorbing module 33, connecting moving pressure block 25 and shock-absorbing module 33. The spring 34 uses elasticity to buffer the impact force when fixing product 18. The other end of shock-absorbing spring 34 is fixedly connected to moving pressure block 25, which moves with sliding module 32.The support column 24 and roller 23 apply pressure to the product 18, fixing it in place. The support column 24 is fixedly connected to the outer wall of the movable pressure block 25, driven by the movable pressure block 25. The roller 23 assists in fixing the product 18, enhancing stability. Roller 23 is rotatably connected to the outer wall of the support column 24, mounted on the support column 24 and rotating. It rotates with the product 18, reducing rotational resistance. A display 2 is fixedly connected to the outer wall of the control base 1. The display 2 receives and displays the tooth surface diameter and outer diameter data of the product 18 detected by dial indicator 13 and dial indicator 21, facilitating operator reading. An alarm light 35 is fixedly connected to the upper surface of the control base 1. The surface is fixedly connected to the lower surface of the fixed base 4. The inner wall of product 18 is rotatably connected to the outer wall of roller 23. The inner wall of product 18 is attached to one end of dial indicator 21. The inner wall of product 18 is rotatably connected to the outer wall of roller 19. Roller 19 contacts product 18 and rotates to drive product 18 to rotate, providing conditions for dial indicator 21 to detect the outer diameter. The outer wall of the fixed platform 11 is fixedly connected to the upper surface of the fixed base 4. The lower surface of the outer wall of product 18 is attached to the upper surface of the fixed platform 11. The outer wall of guide post 6 is fixedly connected to the inner wall of the fixed upper seat 5. The lower surface of support plate 7 is attached to the outer wall of limit block 12. The outer wall of the fixed platform 11 is fixedly connected to the outer wall of fixed module 22. The upper surface of control seat 1 is fixedly connected to the outer wall of fixed bracket 3.

[0021] Specifically, when the parallelism and roundness integrated inspection machine is working, the control base 1 is started, and the motor 31 drives the synchronous wheel 30 to rotate. The synchronous wheel 28 rotates through the track 29. The rotation of the synchronous wheel 28 drives the roller 19 to rotate through the rotating support roller 20 and the linear bearing 27, thereby driving the product 18 to rotate. The dial indicator 21 contacts the product 18 through the fixed module 22 to detect the outer diameter. The data is transmitted to the display 2. The cylinder 26 pushes the sliding module 32 to slide in the slide groove of the fixed bracket 3, which drives the moving pressure block 25 and the shock absorption module 33. The moving pressure block 25 fixes the product 18 with the help of the support column 24 and the roller 23. The shock absorption spring 34 plays a buffering role. This solves the problems of complex operation, low accuracy and unstable data in the existing inspection, and achieves a high degree of automation and convenient operation, improving the inspection efficiency and accuracy.

[0022] Working principle: When using the parallelism and roundness integrated inspection machine, first start the control base 1, then cylinder 8 and cylinder 26 will start. After starting, place product 18 on the fixed platform 11. Then, cylinder 26 pushes the sliding module 32 to slide on the fixed bracket 3. The fixed bracket 3 not only has a sliding groove inside but also fixes cylinder 26. The sliding module 32 drives the moving pressure block 25 and the shock absorption module 33 to move. The shock absorption spring 34 is fixed between the moving pressure block 25 and the shock absorption module 33 to buffer and absorb shock. The movement of the moving pressure block 25 drives the support column 24 and roller 23 to apply pressure to fix product 18. Roller 23 rotates so that it can follow the rotation of product 18 when it rotates. Then, cylinder 8 pushes connecting fork block 9 to move. Connecting fork block 9 detects the tooth surface diameter of product 18. The detected data is displayed on display 2. The movement of connecting fork block 9 causes support plate 7 to slide on guide post 6. At the same time, the movement of support plate 7 causes spring pin 15 and dial indicator 13 to move. Spring pin 15 abuts against product 18 from above. Dial indicator 13 detects product 18. Dial indicator 13 and product 18 are fixed to support plate 7 by spring pin movable block 17. Limiting ring 14 is further fixed to spring pin movable block 17 by bolt 16. This achieves a high degree of automation in the detection process, improves detection efficiency and accuracy, and is easy to operate. It solves the problems of complex operation, low detection accuracy, and unstable data in the existing technology. In addition, the motor 31 outputs to the synchronous pulley 30, and the rotation of the synchronous pulley 30 drives the track 29 to drive the transmission. The track 29 then drives the synchronous pulley 28 to rotate. The rotation of the synchronous pulley 28 drives the linear bearing 27 and the roller 19 to rotate synchronously through the rotating support roller 20. The rotation of the roller 19 causes the product 18 to rotate. The dial indicator 21 is fixed to contact the product 18 through the fixing module 22, so that the dial indicator 21 can detect the outer diameter of the product 18 when the product 18 rotates. The data after detection is displayed on the display 2, which reduces manual intervention, improves detection efficiency, and makes operation convenient.
