Description

Technical Field

[0001] The present invention relates to the technical field of dial indicator detection equipment, and particularly to a multifunctional internal diameter dial indicator calibration device. Background Technique

[0002] The head of an internal diameter dial indicator is a combination of an internal measuring lever-type measuring frame and a dial indicator, which is a measuring instrument that converts the linear displacement of the measuring head into the angular displacement of the pointer, and measures or inspects the inner diameter, deep hole diameter and shape accuracy of parts by the comparative measurement method.

[0003] Traditional internal diameter dial indicator detection usually manually detects the heads one by one. The operator needs to place each dial indicator head on the detection equipment, take it off after the detection, and then perform the next one. This method not only consumes a large amount of manpower and time, but also easily causes fatigue and affects work efficiency. Manual operation is easily affected by human factors, such as the technical level and fatigue degree of the operator, which will all lead to measurement errors. Due to manual operation, the detection may lack a strict standardized process. Especially among different operators, the measured data may be different. Manual detection one by one requires a large amount of manpower, has a high labor intensity, and low detection efficiency. Summary of the Invention

[0015] The present invention provides a multifunctional internal diameter dial indicator calibration device, which has the following beneficial effects:

[0016] 1. The present invention has efficient batch detection capabilities: One of the key technologies in the design of this device is its ability to perform batch detection of the dial indicators' heads. Through precise mechanical transmission and linkage systems, the device can process multiple dial indicator heads at once, rather than detecting them one by one, thus greatly improving the detection efficiency. The linkage mechanism, output belt, and sliding components of the device work together to ensure precise operation and efficient processes during batch operations. The design of the device tightly integrates various functional modules (such as output belts, linkage sliders, feeding components, lifting tooth key platforms, etc.) to form an efficient and stable working system. The compact design not only saves space but also improves the reliability and operational stability of the device.

[0017] 2. The present invention has precise automated control effects: The device utilizes the rotational torque provided by the output motor and conducts and links it through a series of pulley brackets, belts, linkages, and sliders, enabling each component to be precisely synchronized, ensuring the precise docking and vertical movement between the measuring probe of the dial indicator head and the lifting tooth key platform. This automated precise control not only improves the stability of detection but also ensures the reliability and repeatability of the device. During the operation of the device, the linkage lifting component will move up and down along with the movement of the track. When a fault or abnormal operation occurs, the device can automatically stop feeding or conduct fault diagnosis through the set protection mechanism, avoiding greater problems caused by excessive wear or misalignment of the device. This intelligent protection design improves the durability and long-term stability of the device.

[0018] 3. The present invention has automated feeding and discharging functions: The feeding and discharging system of the device is one of its key features. The feeding hopper sends the dial indicator heads into the system and pushes the heads to the working position through the feeding component and auxiliary guide rails. After the detection is completed, the device pushes the detected heads to the discharging track through the linkage system. In this way, the device can achieve automatic feeding, detection, and discharging operations during operation, reducing manual intervention, improving the operation efficiency, and ensuring the continuity of the operation process. The device is designed with curved guide rails, straight rails, and adjustment components.

[0019] 4. The present invention has precise measurement and status detection capabilities: The device can precisely detect the operating status of the dial indicator head through the tooth key structure and surface concavities and convexities of the lifting tooth key platform. The measuring probe of the dial indicator head precisely bounces during the detection process as the lifting tooth key platform moves up and down, thus being able to reflect the working status of the head in real-time. This design improves the detection accuracy and can precisely detect minor errors or faults in the dial indicator head, meeting the high-precision detection requirements. Description of the Drawings

[0032] Please refer to the attached Figure 1 - attached Figure 5 , the embodiment of the present invention provides a multifunctional internal diameter dial indicator calibration device, including an operating table 1 and a linkage table 4. A straight rail 2 is arranged on the top of the operating table 1. The linkage table 4 is located above the operating table 1. A linkage slider 3 is fixedly connected to the side wall of the linkage table 4 in the direction relative to the operating table 1.

Suspension arms 7 are fixedly connected to both sides of the operating table 1, and the suspension arms 7 are symmetric with each other. A feeding hopper 10 is fixedly connected to the side wall of the operating pool 5 at the position of a primary opening. A jacking tooth key platform 8 is fixedly connected to the top of one side suspension arm 7. An introduction ramp 9 is arranged on the side of the jacking tooth key platform 8 facing the operating pool 5. A pulley frame 11 is fixedly connected to the top of the operating table 1 between the straight rails 2. Output pulleys 12 are rotatably connected to both ends of the pulley frame 11. The output pulleys 12 are connected by an output belt 13. A linkage member 17 is fixedly connected to the outer surface of the linkage slider 3.

The top end of the linkage sliding column 16 is slidably connected inside the linkage sliding groove 15. By starting the output motor 14, the generated rotational torque is output to the output pulley 12 installed through the pulley frame 11. The rotation of a single group of output pulleys 12 simultaneously transmits the torque to the output pulley 12 installed in the other direction of the pulley frame 11 through the output belt 13. The output belt 13 itself also operates simultaneously. The linkage member 17 fixed to the outer surface of the output belt 13 also displaces along with the operation of the output belt 13 following the outer shape structure of the output belt 13. After the linkage member 17 completes the operation of one belt side of the output belt 13, it enters the other belt surface of the output belt 13. The linkage sliding column 16 installed on its top also reciprocally slides inside the linkage sliding groove 15 arranged on the linkage table 4. At the same time, the linkage table 4 linearly moves left and right along the linkage slider 3 on the two straight rails 2 arranged on the top of the operating table 1 until it moves to one end and the other end of the output belt 13.

[0033] Please refer to the attached Figure 1 - attached Figure 5, on the inner side walls of the operation pool 5, there is a T-shaped material placing rail 18 fixedly connected between the two side openings at the same time. The two input ports on both sides of the T-shaped material placing rail 18 are aligned with the two side openings of the operation pool 5. A guiding groove 19 is provided between the operation pool 5 and the T-shaped material placing rail 18. At the same time, an extending groove 20 is provided on the bottom wall of the T-shaped material placing rail 18. At the top of the linkage platform 4, there is a transmission crank component 21 located in front of the operation pool 5 at the same time to provide continuous feeding and output for the T-shaped material placing rail 18. The transmission crank component 21 includes a transmission gear 211. The transmission gear 211 is rotatably connected to the top of the linkage platform 4 and is located between the linkage platform 4 and the operation pool 5. A first transmission rod 212 is fixedly connected to the top center of the transmission gear 211. One end of the first transmission rod 212 away from the center of the linkage platform 4 is rotatably connected to a second transmission rod 213. A fixed clamping part 22 is fixedly connected to the side wall of the linkage platform 4 relative to the direction of the introduction ramp 9. A suspension rod 23 is fixedly connected to the bottom of the fixed clamping part 22. A curved guide rail 24 is fixedly connected to the top of the operation table 1. The curved guide rail 24 surrounds the outside of the output belt 13. A linkage lifting component 25 is provided inside the curved guide rail 24. An internal guiding groove 26 is provided inside the linkage lifting component 25. The internal guiding groove 26 is provided with openings on both the top and the side. At the same time, a support frame 27 is slidably connected to the position of one end of the straight track 2 at the top of the curved guide rail 24. The support frame 27 is of a gantry structure. The gantry feet of the support frame 27 are all slidably connected to the top wall of the curved guide rail 24. The two sides of the curved guide rail 24 have 180-degree bending parts. A straight rack 28 is fixedly connected to the top end of the support frame 27. One end of the support frame 27 extending into the curved guide rail 24 is fixedly connected to a jacking component 29. The jacking component 29 cooperates with the straight rack 28 to enable the support frame 27 to jack up the straight rack 28 and rise. The bottom of the feeding hopper 10 is fixedly connected to an auxiliary guide rail 30. The bottom of the inner side wall of the feeding hopper 10 is fixedly connected to a T-shaped feeding rail 31. The bottom of the auxiliary guide rail 30 is fixedly connected to an auxiliary rail 32. The auxiliary rail 32 penetrates through the side wall of the operation pool 5 and extends into the operation pool 5 and is located between the operation pool 5 and the linkage platform 4 at the same time. The T-shaped feeding rail 31 is aligned with the input port of the T-shaped material placing rail 18. A pushing component 33 is provided at the lower part of the feeding hopper 10. A through groove 34 is provided in the middle of the T-shaped feeding rail 31. The operation pool 5 fixed to the top of the linkage platform 4 also moves along with the displacement of the linkage platform 4. At the same time, the feeding hopper 10 storing the dial indicator head also moves along with the displacement of the operation pool 5. When the linkage platform 4 moves, the linkage lifting component 25 installed and fixed through the fixed clamping part 22 and the suspension rod 23 slides along the internal guiding groove 26 inside the curved guide rail 24 on the top of the operation table 1. The external shape of the curved guide rail 24 is the same as that of the output belt 13, so that the linkage lifting component 25 can slide and displace along the track of the curved guide rail 24. The straight rack 28 can contact and engage with the transmission gear 211 included in the transmission crank component 21 at this height. After the transmission gear 211 displaced to the position of the straight rack 28 contacts the straight rack 28, it pushes the transmission gear 211 to rotate in a tooth-key meshing relationship.The drive rod 212 fixed to the axis of the drive gear 211 also rotates accordingly. The outer end of the drive rod 212 simultaneously drives one end of the drive rod 213 to perform a centrifugal rotational motion. The pusher assembly 33 installed and docked at the other end of the drive rod 213 also operates simultaneously inside the auxiliary guide rail 30 and the auxiliary rail 32 provided at the bottom of the feeding hopper 10, and makes the measuring probe at the bottom of the dial indicator head displace along the guiding ramp 9 provided on the side wall of the lifting tooth key platform 8 to the lifting tooth key platform 8 fixed at the top of the suspension arm 7, and passes through the extension slot 20 provided at the bottom of the T-shaped material placement rail 18 and then touches the upper surface of the lifting tooth key platform 8. When the equipment drives the operation pool 5 and the linkage table 4 to perform reciprocating displacement, the lifting tooth key platform 8 passes through the guiding slot 19 provided between the operation pool 5 and the T-shaped material placement rail 18, and forms a relative reciprocating motion state with the T-shaped material placement rail 18 and the dial indicator head inside the T-shaped material placement rail 18 in a static state. The measuring probe at the bottom of the dial indicator head also displaces on the surface teeth of the lifting tooth key platform 8 at the same time, making the measuring probe form an up-and-down motion state, so as to drive the pointer of the dial indicator head to start jumping and measuring following the measuring probe, and use the concave-convex form of the surface of the lifting tooth key platform 8 to detect the operating condition of the dial indicator head. When the linkage lifting assembly 25 enters the bending part of the curved guide rail 24 and the slideway on the other side of the curved guide rail 24, the guiding inclined block 252 disengages from the contact rod 291, so that the lifting assembly 29 drives the support frame 27 and the linear rack 28 to fall due to gravity, the linear rack 28 disengages from the height of the drive curved rod assembly 21, and the reciprocatingly displaced drive curved rod assembly 21 stops operating, thus stopping the feeding until the next group of dial indicator heads are pushed in, and at the same time pushing out the previously processed dial indicator heads, so as to achieve the operation ability of automatic feeding and discharging while detecting the operation of a batch of dial indicator heads.,

[0034] Please refer to the attached Figure 1 and attached Figure 4 At both ends of the in-line rail 2, anti-collision pads 6 are fixedly connected to avoid direct impact on the linkage table 4. At the bottom of the workbench 1, an output motor 14 is fixedly connected, and the bottom end of the rotating shaft of the output belt pulley 12 is fixedly connected to the top motor end of the output motor 14.

[0035] Please refer to the attached Figure 3 - attached Figure 8, the linkage lifting assembly 25 includes a guiding platform 251 which is slidably connected in the built-in guiding groove 26. A guiding inclined block 252 is arranged inside the guiding platform 251. A bearing bracket 253 is fixedly connected to the side wall of the guiding platform 251. The inner ring part of the bearing bracket 253 is fixedly connected to the bottom end of the hanging rod 23. The guiding platform 251 included in the linkage lifting assembly 25 slides along the built-in guiding groove 26 arranged inside the curved guide rail 24. When encountering the bending part of the curved guide rail 24, the bearing bracket 253 fixed to the side of the guiding platform 251 will rotate on the hanging rod 23, enabling the guiding platform 251 to perform a turning slide. When the linkage lifting assembly 25 follows the linkage table 4 to move to the support frame 27 at the end position of the straight track 2, the linkage lifting assembly 25 directly contacts the jacking assembly 29 located at the bottom end of the support frame 27 and inside the curved guide rail 24 at the same time.

[0036] Please refer to the appendix Figure 3 - appendix Figure 9 , the jacking assembly 29 includes a contact rod 291 which is fixedly connected to the bottom end of the support frame 27. The contact rod 291 is arranged in the built-in guiding groove 26. A contact inclined path 292 is arranged on one side of the contact rod 291. The height of the contact rod 291 is lower than the groove depth of the built-in guiding groove 26. The slope structure of the guiding inclined block 252 fixed inside the guiding platform 251 contacts the structure of the contact inclined path 292 arranged at the end of the contact rod 291. The contact rod 291 is integrally lifted inside the built-in guiding groove 26. At the same time, the support frame 27 and the straight rack 28 fixed to the top of the contact rod 291 are integrally lifted, so that the straight rack 28 rises to the height of the transmission curved rod assembly 21 arranged inside the linkage table 4.

[0037] Please refer to the appendix Figure 9 - appendix Figure 10, the material pushing component 33 includes a linkage sliding rod 331. The linkage sliding rod 331 is slidably connected to the lower part of the auxiliary guide rail 30. One end of the bottom of the linkage sliding rod 331 close to the operation pool 5 is rotatably connected to the outer end of the second transmission rod 213. One side of the top of the linkage sliding rod 331 away from the operation pool 5 is fixedly connected with a touch rod 332. The touch rod 332 is slidably connected to the inside of the through groove 34 and the auxiliary guide rail 30, and extends into the T-shaped feeding rail 31 through the through groove 34. The top end of the touch rod 332 is fixedly connected with a material pushing plate 334. The material pushing plate 334 is slidably connected to the side wall of the T-shaped feeding rail 31. A reset spring 333 is fixedly connected to the side wall of the touch rod 332. The reset spring 333 is arranged between the T-shaped feeding rail 31 and the auxiliary guide rail 30. When the linkage sliding rod 331 included in the material pushing component 33 moves centrifugally at one end of the second transmission rod 213, it starts to displace along the auxiliary rail 32 towards the inside of the operation pool 5. The touch rod 332 installed on the top of the linkage sliding rod 331 also displaces along the auxiliary guide rail 30 at the same time and pushes the reset spring 333 arranged between the auxiliary guide rail 30 and the T-shaped feeding rail 31 to compress. And the linkage sliding rod 331 also extends into the T-shaped feeding rail 31 through the through groove 34 arranged at the bottom of the T-shaped feeding rail 31. The dial indicator heads temporarily stored in the feeding hopper 10 fall along the hopper-shaped structure of the feeding hopper 10, so that the bottommost dial indicator head falls onto the T-shaped feeding rail 31. And the material pushing plate 334 arranged at the top end of the touch rod 332 slides inside the T-shaped feeding rail 31 and pushes the whole dial indicator head into the T-shaped placing rail 18.

[0038] Working principle: This device is mainly used for batch detection of the operating status of the dial gauge head of an internal diameter dial gauge. First, the dial gauge heads for key display detection of the internal diameter dial gauge are batch-placed inside the feeding hopper 10. By turning on the output motor 14, the rotational torque generated is output to the output pulley 12 installed through the pulley bracket 11. The rotation of a single set of output pulleys 12 simultaneously transmits the torque to the output pulley 12 installed on the other side of the pulley bracket 11 through the output belt 13. The output belt 13 also operates simultaneously. The linkage member 17 fixed on the outer surface of the output belt 13 also displaces along the outer shape of the output belt 13 following the operation of the output belt 13. After the linkage member 17 completes the operation of one side of the output belt 13, it enters the surface of the other side of the output belt 13. The linkage slide column 16 installed on its top also reciprocally slides inside the linkage chute 15 provided on the linkage table 4. At the same time, the linkage table 4 linearly moves left and right along the two straight tracks 2 provided on the top of the operation table 1 by the linkage slider 3 until it displaces to one end and the other end of the output belt 13. The operation pool 5 fixed on the top of the linkage table 4 also moves following the displacement of the linkage table 4. At the same time, the feeding hopper 10 that temporarily stores the dial gauge heads also moves following the displacement of the operation pool 5. When the linkage table 4 moves, the linkage lifting assembly 25 installed and fixed through the fixed clamp 22 and the hanging rod 23 slides along the built-in guiding groove 2619 inside the curved guide rail 24 on the top of the operation table 1. The external shape of the curved guide rail 24 is the same as that of the output belt 13, enabling the linkage lifting assembly 25 to slide and displace along the track of the curved guide rail 24. The guiding platform 251 included in the linkage lifting assembly 25 slides along the built-in guiding groove 2619 provided inside the curved guide rail 24. When encountering the bending part of the curved guide rail 24, the bearing bracket 253 fixed on the side of the guiding platform 251 rotates on the hanging rod 23, enabling the guiding platform 251 to make a turning slide. When the linkage lifting assembly 25 follows the linkage table 4 and displaces to the support frame 27 at the end of the straight track 2, the linkage lifting assembly 25 directly contacts the jacking assembly 29 located at the bottom of the support frame 27 and inside the curved guide rail 24. The slope structure of the guiding inclined block 252 fixed inside the guiding platform 251 contacts the contact inclined track 292 structure provided at the end of the contact rod 291. The contact rod 291 is integrally lifted inside the built-in guiding groove 2619. At the same time, the support frame 27 and the linear rack 28 fixed on the top of the contact rod 291 are integrally lifted, causing the linear rack 28 to rise to the height of the transmission curved rod assembly 21 provided inside the linkage table 4. At this height, the linear rack 28 can contact and mesh with the transmission gear 211 included in the transmission curved rod assembly 21. After the transmission gear 211 displaced to the position of the linear rack 28 contacts the linear rack 28, it pushes the transmission gear 211 to rotate in a tooth-key meshing relationship. The transmission rod one 212 fixed to the axis of the transmission gear 211 also rotates accordingly. The outer end of the transmission rod one 212 simultaneously drives one end of the transmission rod two 213 to perform a centrifugal rotational movement.On the other hand, the pusher assembly 33 installed and docked at the other end of the transmission rod two 213 also operates inside the auxiliary guide rail 30 and the auxiliary rail 32 provided at the bottom of the feed hopper 10 at the same time. Under the centrifugal movement of one end of the transmission rod two 213, the linkage slide rod 331 included in the pusher assembly 33 starts to displace along the auxiliary rail 32 towards the inside of the working pool 5. The touch rod 332 installed on the top of the linkage slide rod 331 also displaces along the auxiliary guide rail 30 at the same time and pushes the reset spring 333 provided between the auxiliary guide rail 30 and the T-shaped feed rail 31 to compress. The linkage slide rod 331 also extends into the T-shaped feed rail 31 through the through groove 34 provided at the bottom of the T-shaped feed rail 31. The dial indicator heads temporarily stored inside the feed hopper 10 fall along the hopper-shaped structure of the feed hopper 10, so that the bottommost dial indicator head falls onto the T-shaped feed rail 31. The pusher plate 334 provided at the top of the touch rod 332 slides inside the T-shaped feed rail 31, pushing the whole dial indicator head into the T-shaped placement rail 18, and making the measuring probe at the bottom of the dial indicator head displace along the guiding ramp 9 provided on the side wall of the lifting tooth key platform 8 to the lifting tooth key platform 8 fixed on the top of the suspension arm 7, and passing through the extension groove 20 provided at the bottom of the T-shaped placement rail 18 and then touching the upper surface of the lifting tooth key platform 8. When the equipment drives the working pool 5 and the linkage platform 4 to perform reciprocating displacement, the lifting tooth key platform 8 passes through the guiding groove 19 provided between the working pool 5 and the T-shaped placement rail 18, and forms a relative reciprocating motion state with the T-shaped placement rail 18 and the dial indicator head inside the T-shaped placement rail 18 in a static state. The measuring probe at the bottom of the dial indicator head also displaces on the surface teeth of the lifting tooth key platform 8 at the same time, making the measuring probe move up and down, so as to drive the pointer of the dial indicator head to start jumping and measuring. Using the concave and convex form on the surface of the lifting tooth key platform 8, the running condition of the dial indicator head is detected. When the linkage lifting assembly 25 enters the bending part of the curved guide rail 24 and the slideway on the other side of the curved guide rail 24, the guiding inclined block 252 disengages from the contact rod 291, so that the lifting assembly 29 drives the support frame 27 and the linear rack 28 to fall due to gravity. The linear rack 28 disengages from the height of the transmission curved rod assembly 21, and the reciprocatingly displaced transmission curved rod assembly 21 stops operating, thus stopping the feeding until the next group of dial indicator heads are pushed in, and at the same time pushing out the previously processed dial indicator heads, so as to achieve the operation ability of automatic feeding and discharging while batch detecting the running of the dial indicator heads.
