Description

Technical Field

[0001] The invention belongs to the field of detection technology, and more specifically relates to an online detection device for the coaxiality of an internal spline. Background Art

[0002] The internal spline coaxiality online detection device is a device that uses the teeth of a through gauge to perform coaxiality and tooth groove accuracy detection operations on the spline structure at both ends of the spline sleeve, and can be used to complete the detection and judgment of the spline sleeve.

[0003] The patent document with patent number CN114485319A discloses an internal spline precision detection device, including a bottom plate, a cone rod fixing seat is fixedly installed on the top of the bottom plate, a socket is provided on the right side of the cone rod fixing seat, a spline detection cone rod is plugged into the inside of the socket, a limit hole is provided at the top of the spline detection cone rod and located on the inner side of the socket, a limit mechanism is provided on the top of the cone rod fixing seat, a spline detection ring is sleeved on the outer surface of the key detection cone rod, and a soft fastener is sleeved on the outer side of the spline detection ring. The present invention sets a limit mechanism, lifts the top plate upward, and can pull the limit rod out of the limit hole, insert the spline detection cone rod into the inside of the socket, insert the limit rod through the limit hole, design a fixed spline cone rod fixture, and avoid the operation of holding the cone rod; design a nylon sleeve, and the product can be easily taken out of the process by the impact of the sleeve, reducing the labor intensity of the operator and increasing work efficiency.

[0004] There are certain shortcomings in the use of traditional online detection equipment for internal spline coaxiality. Traditional spline detection devices can only detect spline sleeves with single spline structures. When there are two sets of spline structures in the spline, it is impossible to detect the spline accuracy and coaxiality. Usually, a universal display is used to detect the coaxiality of the spline at one end and the outer circle, and then the coaxiality of the spline at the other end and the outer circle is detected for indirect measurement. This detection method is greatly affected by the coaxiality of the outer circles at both ends, and is different from the actual working conditions of the product, and there is a large detection error; secondly, the traditional detection device is inefficient, so it can only detect one spline sleeve at a time, and manual material picking operations are required, which reduces its work efficiency; at the same time, the traditional detection device requires the user to manually judge the detection result. When performing batch detection operations, the detection result of the spline sleeve cannot be judged in time, and the use effect is poor. Summary of the invention

[0005] The purpose of the present invention is to provide an on-line detection device for internal spline coaxiality, which can solve the existing problems.

[0006] The problem to be solved by the present invention is:

[0007] 1. Traditional spline detection devices can only detect spline sleeves with single spline structures. When there are two sets of spline structures in the spline, it is impossible to detect the spline accuracy and coaxiality. Usually, a universal display is used to detect the coaxiality of the spline and the outer circle at one end, and then the coaxiality of the spline and the outer circle at the other end is detected for indirect measurement. This detection method is greatly affected by the coaxiality of the outer circles at both ends, and is also different from the actual working conditions of the product, resulting in large detection errors;

[0008] 2. The traditional detection device has low efficiency, so it can only detect one spline sleeve at a time, and it needs manual material removal operation, which reduces its work efficiency;

[0009] 3. The traditional detection device requires the user to manually judge the detection result. When performing batch detection operations, the detection result of the spline sleeve cannot be judged in time, and the use effect is poor.

[0010] The purpose of the present invention can be achieved through the following technical solutions:

[0011] An online detection device for the coaxiality of an internal spline comprises a first gauge, a second gauge and a box shell, wherein the second gauge is spliced ​​and installed at the lower front end position of the box shell, and the first gauge is spliced ​​and installed at the upper front end position of the box shell, an outer surface of one end of the first gauge is provided with a first through gauge tooth for docking the spline structure of one end of the spline sleeve, an outer surface of one end of the second gauge is provided with a second through gauge tooth for docking the spline structure of the other end of the spline sleeve, a docking clamp is fixedly installed at the middle position of the outer surface of one end of the first gauge, an outer diameter ferrule for matching with the docking clamp is fixedly installed at the middle position of the outer surface of one end of the second gauge, a docking slot is provided in the middle of the outer surface of the outer diameter ferrule, the first gauge and the box shell are movably connected through a lifting clamp seat, and the second gauge and the box shell are docked through a fixed base.

[0012] As a further technical solution of the present invention, a lifting platform is movably installed on the upper part of the fixed base, and the fixed base and the lifting platform are movably connected by two second hydraulic rods. A second plug rod is provided at the other end of the second gauge. The user inserts the second plug rod of the second gauge into the slot of the fixed base to complete the installation operation of the second gauge. The user installs the spline sleeve to be tested on the upper part of the second gauge, so that the second through gauge teeth and the spline structure at one end of the spline sleeve are butted against each other to detect the quality of the spline. The user starts the first hydraulic rod, so that the first hydraulic rod drives the first gauge downward, so that the first through gauge teeth of the first gauge are inserted into the spline structure at the other end of the spline sleeve, and at the same time, the butt joint groove and the butt joint head are butt jointed with each other to detect the coaxiality of the spline structure at both ends of the spline sleeve.

[0013] As a further technical solution of the present invention, a rubber sleeve for docking with the second insertion rod is fixedly installed on the inner side of the fixed base, and a plurality of groups of slots for docking with the spline sleeves are provided on the upper part of the lifting platform. After a plurality of spline sleeves complete the spline detection operation, the user can start the second hydraulic rod so that the second hydraulic rod drives the lifting platform to move up, thereby ejecting the spline sleeves for batch detection and completing the material removal operation of the spline sleeves.

[0014] As a further technical solution of the present invention, a first insertion rod is provided at the other end of the first gauge, and a prompt plate used in conjunction with the first gauge is movably installed on the side of the lifting base. When the first gauge moves downward, the user can judge the coaxiality and tooth groove accuracy of the spline sleeve according to the state of the prompt plate.

[0015] As a further technical solution of the present invention, a limit card plate is fixedly installed at the middle position of one side of the prompt plate, and a docking groove used for matching the limit card plate is provided on the side of the lifting card seat. A spring is fixedly installed on the outer surface of the upper end of the limit card plate, and a fixed sleeve is provided on the upper end of the spring. The limit card plate and the lifting card seat are elastically connected by a spring. The two color cards are red and green respectively. In the normal state of the first inspection fixture, the color card color displayed on the prompt plate on the lifting card seat is green. When the user starts the first hydraulic rod, the first hydraulic rod drives the lifting card seat to move downward, so that the lifting card seat drives the first inspection fixture to dock with the spline sleeve. If there is an error in the coaxiality or tooth groove accuracy of the splines at both ends of the spline sleeve, the first through gauge tooth corresponding to the first inspection fixture cannot be inserted into the spline sleeve normally, so that when the lifting card seat moves downward, the corresponding first inspection fixture pushes the prompt plate upward through the first insertion rod, thereby adjusting the color card position of the prompt plate, so that the color card color displayed on the prompt plate on the lifting card seat is red, thereby prompting the operator that the spline sleeve at this location has quality defects.

[0016] As a further technical solution of the present invention, the outer surface of the lower end of the limit card plate is provided with a fixed sleeve for docking with the first insertion rod, and the outer surface of the side of the prompt plate is provided with two color cards. The fixed sleeve plays a docking and fixing role in the installation of the first insertion rod, and the user can quickly judge the detection result of the spline sleeve by moving the position of the two color cards.

[0017] As a further technical solution of the present invention, material collecting boxes are fixedly installed on the outer surfaces of both sides of the box shell, and the outer surfaces of both sides of the box shell are provided with lifting grooves used in conjunction with the first hydraulic rod. Two sets of material collecting boxes can be used to separate and store defective spline sleeves and qualified spline sleeves respectively.

[0018] As a further technical solution of the present invention, an inspection cover is movably installed at the front end of the box shell, and a side-screw upper cover is movably installed at the upper end of the box shell. By opening the inspection cover and the side-screw upper cover, the lifting base and the fixed base can be inspected and replaced.

[0019] Beneficial effects of the present invention:

[0020] 1. By setting the first inspection tool and the second inspection tool, when the internal spline coaxiality online inspection device performs inspection operation on the spline sleeve of the double spline structure, the user can install the first inspection tool and the second inspection tool on the upper and lower parts of the housing shell respectively, and improve the through gauge structure on the first inspection tool and the second inspection tool, add a docking card head to the first through gauge tooth end of the first inspection tool, and add a docking card slot to the second through gauge tooth end of the second inspection tool, and the docking card slot and the docking card head adopt a card connection docking method. When the coaxiality of the spline sleeve is inspected, the first through gauge tooth of the first inspection tool and the second through gauge tooth of the second inspection tool are respectively inserted into the different sizes of the two ends of the spline sleeve. In a small spline hole, if the docking clamp of the first through gauge tooth on the first gauge can be smoothly inserted into the docking groove of the second through gauge tooth on the second gauge, it means that the coaxiality of the spline holes of different sizes at both ends of the spline sleeve is good. If the docking clamp of the first through gauge tooth on the first gauge cannot be inserted into the docking groove of the second through gauge tooth on the second gauge, it means that the coaxiality of the spline holes of different sizes at both ends of the spline sleeve is poor. Local improvements are made on the basis of the spline through gauge teeth. The precise cooperation of the docking groove and the docking clamp is used to realize the online detection of the coaxiality of the two internal splines. The structure is simple and the production is convenient, so it can be applied to the detection operation of the two internal splines, and its use effect is improved.

[0021] 2. By setting a lifting card seat and a fixed base, when the internal spline coaxiality online detection device is used, the lifting card seat and the fixed base are used to form a lifting type multi-group detection structure. The lifting card seat and the fixed base can be inserted and installed with multiple sets of first inspection tools and second inspection tools by setting multiple sets of fixed sleeves and rubber sleeves. When performing the inspection operation of multiple spline sleeves, the user installs the spline sleeve to be inspected on the upper part of the second inspection tool, so that the second through gauge teeth and the spline structure at one end of the spline sleeve are connected with each other to detect the spline quality. The user starts the first hydraulic rod, so that the first hydraulic rod drives the first The inspection fixture moves downward, and the first through-gauge tooth of the first inspection fixture is inserted into the spline structure at the other end of the spline sleeve. At the same time, the docking slot and the docking clamp head are docked with each other to detect the coaxiality of the spline structures at both ends of the spline sleeve, thereby completing the inspection operation of multiple groups of spline sleeves at the same time. At the same time, the user can start the second hydraulic rod to drive the lifting platform to move up, thereby ejecting the spline sleeves inspected in batches, and completing the material removal operation of the spline sleeves. By utilizing the setting of the lifting card seat and the fixed base, the spline sleeve inspection operation can be carried out in batches, and at the same time, it has an ejection type material removal structure to improve its use effect.

[0022] 3. By setting a reminder plate and a limit card plate, when the internal spline coaxiality online detection device is used, the two color cards are red and green respectively. When the first inspection tool is in a normal state, the reminder plate is in a reset initial state through a spring. At this time, the color card color displayed on the reminder plate on the lifting card seat is green. When the user starts the first hydraulic rod, the first hydraulic rod drives the lifting card seat to move downward, so that the lifting card seat drives the first inspection tool to dock with the spline sleeve. If the coaxiality or tooth groove accuracy of the splines at both ends of the spline sleeve has a large error, the first through gauge tooth corresponding to the first inspection tool cannot be normally inserted into the spline sleeve, thereby causing When the lifting card seat moves downward, the corresponding first inspection fixture pushes the prompt plate upward through the first insertion rod, thereby adjusting the color card position of the prompt plate, so that the color card color displayed on the prompt plate on the lifting card seat is red, thereby prompting the operator that the spline sleeve at this location has quality defects; if the coaxiality or tooth groove accuracy of the splines at both ends of the spline sleeve is qualified, the first inspection fixture normally docks with the spline sleeve, so that the color of the color card displayed on the corresponding prompt plate on the lifting card seat remains green, and the spline sleeve is qualified in the inspection, so that the user can quickly judge the inspection result of the spline sleeve, thereby improving the working efficiency of the online inspection equipment for the coaxiality of the internal spline.

[0032] A lifting platform 2 is movably installed on the upper part of the fixed base 24, and the fixed base 24 and the lifting platform 2 are movably connected by two second hydraulic rods 23. A second plug rod 16 is provided at the other end of the second gauge 8. The user inserts the second plug rod 16 of the second gauge 8 into the slot of the fixed base 24 to complete the installation operation of the second gauge 8. The user installs the spline sleeve 14 to be tested on the upper part of the second gauge 8, so that the second through-gauge teeth 9 and the spline structure at one end of the spline sleeve 14 are butted against each other to detect the quality of the spline. The user starts the first hydraulic rod 4, so that the first hydraulic rod 4 drives the first gauge 7 to move downward, so that the first through-gauge teeth 13 of the first gauge 7 are inserted into the spline structure at the other end of the spline sleeve 14, and at the same time, the docking slot 10 and the docking clamp head 11 are butted against each other to detect the coaxiality of the spline structure at both ends of the spline sleeve 14.

[0033] A rubber sleeve 25 for docking with the second insertion rod 16 is fixedly installed on the inner side of the fixed base 24. A plurality of groups of slots for docking with the spline sleeves 14 are provided on the upper part of the lifting platform 2. After a plurality of spline sleeves 14 complete the spline detection operation, the user can start the second hydraulic rod 23 so that the second hydraulic rod 23 drives the lifting platform 2 to move upward, thereby ejecting the spline sleeves 14 for batch detection and completing the material removal operation of the spline sleeves 14.

[0034] A first insert rod 12 is provided at the other end of the first inspection fixture 7, and a prompt plate 18 used in conjunction with the first inspection fixture 7 is movably installed on the side of the lifting base 17. When the first inspection fixture 7 moves downward, the user can judge the coaxiality and tooth groove accuracy of the spline sleeve 14 according to the state of the prompt plate 18.

[0035] A limit card plate 22 is fixedly installed in the middle of one side of the prompt plate 18, and a docking groove 19 used for matching the limit card plate 22 is provided on the side of the lifting card seat 17. A spring 21 is fixedly installed on the outer surface of the upper end of the limit card plate 22, and a fixed card sleeve 20 is provided on the upper end of the spring 21. The limit card plate 22 and the lifting card seat 17 are elastically connected by the spring 21. The two color cards 27 are red and green respectively. In the normal state of the first inspection fixture 7, the color of the color card 27 displayed on the lifting card seat 17 by the prompt plate 18 is green. When the user starts the first hydraulic rod 4, the first hydraulic rod 4 drives the lifting When the lowering seat 17 moves downward, so that the lifting seat 17 drives the first inspection fixture 7 to dock with the spline sleeve 14, if there is an error in the coaxiality or tooth groove accuracy of the splines at both ends of the spline sleeve 14, the first through gauge tooth 13 of the corresponding first inspection fixture 7 cannot be normally inserted into the spline sleeve 14, so that when the lifting seat 17 moves downward, the corresponding first inspection fixture 7 pushes up the prompt plate 18 through the first insertion rod 12, thereby adjusting the position of the color card 27 of the prompt plate 18, so that the color card 27 displayed on the lifting seat 17 by the prompt plate 18 is red, thereby prompting the operator that the spline sleeve 14 at this location has quality defects.

[0036] The outer surface of the lower end of the limit card plate 22 is provided with a fixing sleeve 28 for docking with the first insertion rod 12, and the outer surface of the side of the prompt plate 18 is provided with two color cards 27. The fixing sleeve 28 plays a docking and fixing role in the installation of the first insertion rod 12. By moving the position of the two color cards 27, the user can quickly determine the detection result of the spline sleeve 14.

[0037] The outer surfaces of both sides of the box shell 1 are fixedly installed with material receiving boxes 3, and the outer surfaces of both sides of the box shell 1 are provided with lifting grooves 5 used in conjunction with the first hydraulic rod 4. Two sets of material receiving boxes 3 can be used to separate and store defective spline sleeves 14 and qualified spline sleeves 14 respectively.

[0038] An inspection cover 26 is movably mounted on the front end of the box shell 1, and a side-screw upper cover 6 is movably mounted on the upper end of the box shell 1. By opening the inspection cover 26 and the side-screw upper cover 6, the lifting base 17 and the fixed base 24 can be inspected and replaced.

[0039] The internal spline coaxiality online detection device is provided with a first inspection tool 7 and a second inspection tool 8. When the internal spline coaxiality online detection device performs a detection operation on a spline sleeve 14 of a double spline structure, the user can install the first inspection tool 7 and the second inspection tool 8 on the upper and lower parts of a box shell 1 respectively, and improve the through gauge structure on the first inspection tool 7 and the second inspection tool 8, by adding a docking clamp 11 at the end of the first through gauge tooth 13 of the first inspection tool 7, and adding a docking slot 10 at the end of the second through gauge tooth 9 of the second inspection tool 8, and the docking slot 10 and the docking clamp 11 adopt a card-type docking method. When the coaxiality of the spline sleeve 14 is detected, the first through gauge tooth 13 of the first inspection tool 7 and the second through gauge tooth 9 of the second inspection tool 8 are respectively inserted into the spline sleeve 14. In the spline holes of different sizes at both ends of the key sleeve 14, if the docking clamp 11 of the first through-gauge tooth 13 on the first inspection fixture 7 can be smoothly inserted into the docking slot 10 of the second through-gauge tooth 9 on the second inspection fixture 8, it means that the coaxiality of the spline holes of different sizes at both ends of the spline sleeve 14 is good. If the docking clamp 11 of the first through-gauge tooth 13 on the first inspection fixture 7 cannot be inserted into the docking slot 10 of the second through-gauge tooth 9 on the second inspection fixture 8, it means that the coaxiality of the spline holes of different sizes at both ends of the spline sleeve 14 is poor. Local improvements are made on the basis of the spline through-gauge teeth. The precise matching of the docking slot 10 and the docking clamp 11 is used to realize the online detection of the coaxiality of the two internal splines. The structure is simple and the production is convenient, so that it can be applied to the detection operation of the two internal splines, and its use effect is improved.

[0040] By setting the lifting card seat 17 and the fixed base 24, when the internal spline coaxiality online detection device is used, the lifting card seat 17 and the fixed base 24 are used to form a lifting type multi-group detection structure. The lifting card seat 17 and the fixed base 24 can be inserted and installed with multiple groups of first inspection tools 7 and second inspection tools 8 by setting multiple groups of fixed sleeves 28 and rubber sleeves 25. When performing the detection operation of multiple spline sleeves 14, the user installs the spline sleeves 14 to be detected on the upper part of the second inspection tool 8, so that the second through gauge teeth 9 and the spline structure at one end of the spline sleeve 14 are connected to each other to detect the spline quality. The user starts the first hydraulic rod 4 so that the first hydraulic rod 4 drives the first inspection tool 7 to be detected. The tool 7 is moved downward, so that the first through-gauge tooth 13 of the first inspection tool 7 is inserted into the spline structure at the other end of the spline sleeve 14, and the docking card slot 10 and the docking card head 11 are docked with each other, and the coaxiality of the spline structure at both ends of the spline sleeve 14 is detected, so that the detection operation of multiple groups of spline sleeves 14 is completed at the same time. At the same time, the user can start the second hydraulic rod 23, so that the second hydraulic rod 23 drives the lifting platform 2 to move upward, so as to eject the spline sleeves 14 that are tested in batches, and complete the material collection operation of the spline sleeves 14. By using the setting of the lifting card seat 17 and the fixed base 24, the spline sleeve 14 detection operation can be carried out in batches, and at the same time, it has an ejection type material collection structure to improve its use effect;

[0041] By setting the prompt plate 18 and the limit card plate 22, when the internal spline coaxiality online detection device is used, the two color cards 27 are red and green respectively. In the normal state of the first inspection fixture 7, the prompt plate 18 is in the reset initial state through the spring 21. At this time, the color card 27 displayed by the prompt plate 18 on the lifting card seat 17 is green. When the user starts the first hydraulic rod 4, the first hydraulic rod 4 drives the lifting card seat 17 to move downward, so that the lifting card seat 17 drives the first inspection fixture 7 to dock with the spline sleeve 14. If the coaxiality or tooth groove accuracy of the splines at both ends of the spline sleeve 14 has a large error, the first through gauge tooth 13 corresponding to the first inspection fixture 7 cannot be normally inserted into the spline sleeve 14, thereby causing the lifting card seat 17 to drive the first inspection fixture 7 to dock with the spline sleeve 14. When the lowering seat 17 moves downward, the corresponding first inspection fixture 7 pushes up the prompt plate 18 through the first insertion rod 12, thereby adjusting the position of the color card 27 of the prompt plate 18, so that the color card 27 displayed by the prompt plate 18 on the lifting seat 17 is red, thereby prompting the operator that the spline sleeve 14 at this location has quality defects. If the coaxiality or tooth groove accuracy of the splines at both ends of the spline sleeve 14 is qualified, the first inspection fixture 7 normally docks with the spline sleeve 14, so that the color of the color card 27 displayed by the corresponding prompt plate 18 on the lifting seat 17 remains green, then the spline sleeve 14 is qualified in the inspection, so that the user can quickly judge the inspection result of the spline sleeve 14, thereby improving the working efficiency of the online inspection equipment for the coaxiality of the internal spline.
